Rating of the best tripods for indicators for 2022

The instrument stand is designed to securely fasten the indicators of measuring instruments. It consists of a massive metal base in which a magnet is placed. The set depends on the type of tripod.

Magnetic tripods and racks for indicator heads are distinguished by the presence of a table at the rack, in the form of a plate, for placing the measured parts on it. On tripods there is only a measuring head. Users often mistakenly combine the two. Magnetic tripods perform one function - measuring, but they differ in power, rigidity, and fastening strength. The article contains a rating of the best tripods for indicator heads for 2022.

Where and how is it applied

Not a single enterprise can do without a dial indicator, and the suspension system always goes in tandem with a tripod, often magnetic. Since it is the magnetic system that makes the structure heavier and makes it easier to work with the measuring arrow.

The device is used to establish relative measurements and track deviations from the desired dimensions of a given shape of parts. The indicator shows how much the received part differs from the accepted standard. And in the future it is adjusted or disposed of. Such a device helps large enterprises to significantly save the budget, on the purchase of expensive devices and time. Holders for the device must be as fixed as possible and meet the requirements of GOST for rigidity. Tripods are either voluminous and heavy, or tightly screwed to a flat surface. The magnetic base of such racks and tripods is attracted to metal and helps to avoid problems with finding a convenient place and position for the device.

Clock-type indicators are used in the manufacture of instruments and parts, mechanical engineering, metalworking, to measure deviations in the properties and quality of metals, to tune mechanisms, to determine the percentage of equipment wear. At the same time, a good tripod and stand will last a long time, with careful use. Attachments are subject to frequent change.

How to use

• The dial is set to 0 - this is the starting position (reference).
• The measuring rod is lifted with the help of the "ear" located on top of the BHI and at the same time the reference part is removed from under the indicator.
• measured the part is placed between the measuring head and the tripod base (hard metal ball).
• The measuring rod is lowered.
• Readings of the deviation of the dimensions of the part from the reference measurement on the dial are taken.

GOST

Since 1970, state quality standards for these devices have not changed, but were adjusted in 1998. The following designations are present in the Soviet quality document:

• C - magnetic stand;
• low magnetic tripods SHM - IIN and high SHM-IIB.

Parameters for CMM - IН:

• column height :250mm and above;
• rod overhang: 200 mm;
• head hole diameter: 8mm;

The parameters for the ideal of foreign products do not differ much.

The design of SHM - IIN and SHM-IIB are similar:

• magnetic base for the column;
• kernel;
• indicator connection device;
• spring-loaded hinge.

General rules for commissioning a tripod:

• the design of the product satisfies the condition: the installed indicator head is installed in all positions;
• no perceptible pitching when mounted on a first class surface plate;
• detachment force of the tripod from the surface with a roughness of 0.25 microns - 30 kg;
• allowable tripod deflection 5 m;
• displacement of the microscrew of fine installation is not more than 0.0100;
• full stroke over 3 mm.

For non-magnetic tripods, the stiffness is calculated as follows: 0.1 kg / 0.005 mm = 20 m / 1 mm.

For magnetic fixtures, flatness tolerance is not assigned. Warranty for Soviet models 18 months.

USSR, China and Germany

The tripods most in demand on the market are divided into: by price - cheap, expensive, by manufacturer - domestic and foreign. Each model in the line of this or that company differs in one way or another in characteristics.Yet each manufacturer has distinctive features. For China, this is a low price, for Germany - new technologies, for Soviet tripods - a convincing design and durability.

China

Chinese models, all as one, defines the cam mechanism. The rods put pressure on the ball, with the help of which the fixation to the bracket takes place. Such tripods are not advised to be used in professional activities, and the inhabitants give advice: they bought a Chinese tripod from AliExpress, immediately check for suitability by scrolling the ball with which the mechanism is attached to the platform. It often happens that the holder sticks, and creases and burrs are initially present on the plastic parts.

Chinese models of low prices, from 850 to 1200 rubles, are made of aluminum, with a steel ball and plastic fasteners. The manufacturer recommends that the buyer keep the device switched on to avoid demagnetization. Depending on the price and size, these tripods can withstand weight from 5 to 30 kg. Another problem is the inability to install the indicator in the right place, due to the wrong location of the screw, on almost all Chinese models. However, these products are in high demand due to their low price. And they are perfect for home use.

Germany

This manufacturing country has very expensive and mid-priced models. There is a cam mechanism and a convenient flexible base. And also, it was the manufacturers from Germany who made the perfect hydraulic tripod for the clock suspension mechanism. The product has an accurate fine adjustment, without errors. Oil is poured into the hydraulic rack, in the middle there is a holder for the indicator, which is also clamped with a screw.According to experts, this tripod is the best for accurate measurements. The price varies 15 - 22 thousand rubles.

Soviet

The main disadvantage of Soviet models is the lack of a prism required for mounting on a round or curved surface. A powerful body, a magnetic base, which helps to make clear measurements, thanks to the traction and the correct moderate tension of the rod, is also a minus - this design is overall and weighty, about 5-6 kg, when the weight of the hydraulic 2 kg. If the magnet is working, such a tripod can withstand up to 80 kg. In the event of a breakdown, the craftsmen are advised to contact a specialist; during repairs, it is not allowed to disassemble the base with a magnet, since the stand is also magnetized during production, and there is a chance of damaging the device. The monolithic Soviet design is adjusted according to GOST up to 0.0100. Has high rigidity, and a deflection of 5 microns. With strong vibration, the system finds equilibrium. The scale enters its original position. Average price: 4 - 9 thousand rubles.

The comparative table shows the indicators of four mechanisms: Chinese with a height of 335 mm; Chinese 175 mm, hydraulic (Germany) and Soviet terminal. It can be seen from the calculations that the Chinese tripod with a height of 335 mm has the highest magnet power, not a strong deflection and the lowest rigidity. From this follows the conclusion that: rigidity does not affect the measurement error and load power.

When choosing a tripod, take into account the fact that there is no suspension in the kit - a clockwork. The indicator is selected according to the price and quality of the tripod. So on a budget Taiwanese tripod, they don’t put an expensive German suspension.

Homemade tripod

This master class on making a tripod for dial indicators will help you save on the purchase of an expensive instrument. The components of a tripod are often easy to find at home or purchased for a small price. For a homemade rack you will need:

• base-holder;
• 2 shafts of 179 mm each and a diameter of 10 mm, if you buy, then SFC10, one shaft, with an M4 thread for attaching to the base;
• support for a tripod with a circumference of 8 mm;
• supports 3 pcs.

Since this invention does not involve the presence of a magnet in the base, the support must have an impressive weight to prevent pitching. The base - the holder is taken from heavy metal, not from aluminum and definitely not from wood.

Step-by-step instruction:

• a drill in the base makes a recess (hole) of 6 mm and a diameter of 10 mm, the tripod will be installed vertically, exactly in the middle;
• the bases are sawn off at the shaft holders;
• to fix the holders to each other, a hole with an M4 thread is made on the side. The recess is 0.4 mm.
• the indicator is fixed in the SK8 support with wing screws;
• after all the details are ready, you can assemble the tripod.

For the stability of the structure, on the sides of the platform on which the shaft rests, it is advisable to drill holes in order to fix the invention on the surface, if necessary. If everything is done correctly, then during measurements, the indicator needle will “jump” by a maximum of 0.01, as in conventional purchased average statistical devices.
