Description

Fixtures for repairing vernier calipers

technical field

The utility model belongs to the technical field of auxiliary measuring fixtures, in particular to a fixture for repairing a vernier caliper.

Background technique

The vernier caliper is the most commonly used measuring tool in the machinery manufacturing industry, and it has a wide range of uses. The surface roughness requirement of the vernier caliper depth measuring rod and measuring surface is Ra0.8μm. For a caliper with a depth measuring rod, when verifying the depth measuring rod, place two gauge blocks with a size of 20mm on a level 1 plate so that the gauge The measurement surface of the body is in contact with the gauge block, and the measurement surface of the measuring rod is extended to contact the flat plate, and then read on the ruler body. The error of the indicated value at this point should not exceed the specified value. Therefore, in the measurement, the accuracy of the vernier caliper is very important. For a long time, due to the large number of products that need to be measured with vernier calipers, the frequency of use of measuring tools is relatively frequent. At the same time, some employees' incorrect use has caused damage and wear of vernier calipers, which has greatly increased the amount of repairs. In the prior art, it takes 2 to 3 hours to repair a vernier caliper, which is time-consuming and labor-intensive, and it is not easy to guarantee the repair quality.

Contents of the invention

The purpose of the utility model is to overcome the above shortcomings and provide a simple structure, high precision, quick and easy fixture for repairing the vernier caliper.

The purpose of this utility model and its main technical problems are solved by adopting the following technical solutions:

The fixture for repairing the vernier caliper of the utility model includes a fixture main body, a pressing plate, and a fastening screw. The upper part of the fixture main body is equipped with a pressing plate. There is a groove, and a boss is arranged in the middle of the pressing plate, and the groove is matched with the boss.

The above fixture for repairing the vernier caliper, wherein: the groove is a rectangular groove.

The above fixture for repairing the vernier caliper, wherein: the boss is a rectangular boss.

The above-mentioned clamp for repairing the vernier caliper, wherein: there are four fastening screws.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. It can be seen from the above technical scheme that a groove is provided in the middle of the main body of the fixture, and a boss is arranged in the middle of the pressure plate. The groove and the boss cooperate to not only realize the grinding of the groove and the boss for the caliper sounding working surface, but also make the pressure plate Reliable positioning is carried out with the main body of the fixture, and at the same time, the main body of the fixture and the pressure plate are connected by fastening screws installed at the corner ends, which further ensures the reliability of positioning. In addition, the material of the main body of the fixture is the discarded thread rolling board, which can achieve the purpose of saving materials. The material of the pressing plate can be selected from the plate, and the fixing screws are selected from ordinary screws. It can be seen that the utility model not only ensures the flatness and roughness of the measuring surface, but also greatly improves the repair efficiency, reduces the labor intensity of the repair personnel, and has a simple structure and hardly increases the cost.

Detailed ways

Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the clamp for repairing the vernier caliper proposed according to the utility model will be described in detail as follows.

Referring to Fig. 1 to Fig. 3, the clamp for repairing the vernier caliper of the utility model includes a clamp main body 1, a pressure plate 2, and a fastening screw 4. The upper part of the clamp main body 1 is equipped with a pressure plate 2, and the clamp main body 1 and the pressure plate 2 are installed through the corner end. The fastening screws 4 are connected together, wherein: a groove 3 is arranged in the middle of the clamp body 1 , and a boss 5 is arranged in the middle of the pressure plate 2 , and the groove 3 is matched with the boss 5 . The groove 3 is a rectangular groove. The boss 5 is a rectangular boss. There are four fastening screws 4 .

When in use, the clamp body 1 is placed on the grinding plate, the caliper 6 is close to the groove 3 in the middle of the clamp body 1, and the pressing plate 2 is covered so that the boss 5 is in slight contact with the caliper 6 . Use fastening screws 4 to slightly fix the clamp body 1 and the pressure plate 2, adjust the position of the caliper 6 in the middle groove 3 of the clamp body 1, and make the sounding working surface of the caliper 6 and the working surface of the clamp body 1 perpendicular to the grinding plate , and flush with the grinding surface of the fixture main body 1, tighten the fastening screw 4, and then the caliper 6 can be repaired.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any modifications made to the above embodiments according to the technical essence of the present utility model do not deviate from the content of the technical solution of the present utility model.
