Ranking of the best indicator tripods for 2020

The instrument stand is designed for firmly holding the indicators of measuring instruments. Consists of a massive metal base in which a magnet is placed. The package contents depend on the type of tripod.

Magnetic tripods and stands for indicator heads are distinguished by the presence of a plate at the counter, in the form of a plate, for placing the measured parts on it. The tripods have only a measuring head. Users often mistakenly combine the two. Magnetic tripods perform one function - measuring, but differ in power, rigidity, and fastening strength. This article has compiled a ranking of the best indicator head tripods for 2020.

Where and how it is 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 pointer.

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 later it is adjusted or disposed of. Such a device helps large enterprises to significantly save the budget, the purchase of expensive devices and time. Holders for the device should be as stationary as possible and meet the requirements of GOST for rigidity. Tripods are either bulky and heavy, or screwed tightly to a flat surface. The magnetic base of such stands and tripods is attracted to metal and helps to avoid problems with finding a convenient place and position for the device.

Dial indicators are used in the production of devices and parts, mechanical engineering, metalworking, to measure deviations in the properties and quality of metals, to adjust mechanisms, to find out the percentage of equipment wear. At the same time, a good tripod and stand will last a long time if used carefully. Attachments are subject to frequent change.

Order of use

• The dial is set at 0 - this is the initial position (reference).
• The measuring rod is lifted with the help of the "ear" located on top of the ICT 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 base of the tripod (a ball of hard metal).
• The dipstick is lowered.
• Readings are taken of the deviation of the size of the part from the reference measurement on the dial.

GOST

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

• C - magnetic stand;
• low magnetic tripods ШМ - IIН and high ШМ-IIВ.

Parameters for CMM - IIH:

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

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

The design of the ShM - IIH and ShM-IIV are similar:

• magnetic base for the column;
• kernel;
• indicator supply device;
• a hinge compressed by a spring.

General rules for putting the tripod into operation:

• the design of the product satisfies the condition: the installed indicator head is installed in all positions;
• no perceptible pitching when installed on a first class surface plate;
• force of separation of the tripod from the surface with a roughness of 0.25 microns - 30 kg;
• allowable tripod deflection 5 m;
• fine adjustment microscrew movement no more than 0.0100;
• full stroke more than 3 mm.

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

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

USSR, China and Germany

The most popular tripods on the market are divided: 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 its 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

The Chinese models, all as one, are defined by the cam mechanism. The rods press on the ball, with the help of which it is fixed to the bracket. Such tripods are not advised to be used in professional activities, but ordinary people give advice: you 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 jams, and the plastic parts initially have creases and burrs.

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 support a weight of 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, such products are in high demand due to their low price. And they are quite suitable for domestic use.

Germany

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

Soviet

The main disadvantage of Soviet models is the absence of a prism necessary for mounting on a round or curved surface. A powerful body, a magnetic base, which helps to make accurate measurements, thanks to the pull and the correct moderate tension of the rod, is also a minus - such a design is overall and weighty, about 5-6 kg when the weight of the hydraulic is 2 kg. If the magnet is working properly, such a tripod will hold up to 80 kg. In the event of a breakdown, the masters advise you to contact a specialist; during repairs, it is not allowed to disassemble the base with a magnet, since the stand is also magnetized in production, and there is a possibility of spoiling the device. Monolithic Soviet construction is adjusted according to GOST up to 0.0100. It has high rigidity and a deflection of 5 microns. With strong vibration, the system finds balance. The scale returns to 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 a Chinese tripod with a height of 335 mm has the highest magnet power, not a strong deflection and the lowest rigidity. From this it follows that: rigidity does not affect the measurement error and load power.

When choosing a tripod, the fact that there is no suspension - a clock mechanism - is taken into account. The indicator is selected according to the price and quality of the tripod. So on a budget Taiwanese tripod, do not put an expensive German suspension.

Homemade tripod

This master class on making a tripod for dial gauges will help you save on the purchase of an expensive device. Tripod components can often be found 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 fastening to the base;
• support for a tripod with a circumference of 8 mm;
• supports 3 pcs.

Since this invention does not involve a magnet in the base, the support must be heavy to prevent rolling. The base - the holder is taken from heavy metal, not from aluminum and certainly not from wood.

Step-by-step instruction:

• a drill in the base makes a recess (hole) 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. Deepening is made by 0.4 mm.
• the indicator is fixed in the SK8 support with thumbscrews;
• After all the parts are ready, you can assemble the tripod.

For the stability of the structure, on the sides of the platform on which the shaft is supported, it is advisable to drill holes in order, if necessary, to fix the invention on the surface. If everything is done correctly, then when measuring, the indicator arrow will "jump" by a maximum of 0.01, as in conventional purchased average devices.
