Problems solved by technology

[0002] The piston is regarded as the core part of the oil cylinder and shock absorber. It is particularly important to check whether the dimensions of the piston meet the design requirements. The conventional measuring tool for measuring the outer diameter of the piston is a micrometer for the outer diameter. Because the piston ring on the piston of some products is Composite materials have slight elasticity.

Abstract

The invention discloses a device for measuring outer diameter, which comprises a base, and is characterized in that a stopper is provided at one end of the base, a raised rib is provided in the middle of the base, and on the base between the stopper and the rib A socket is provided, and two horizontal positioning columns are fixed on the side wall of the block. The rib plate is provided with a horizontal through hole, and a horizontal notch connected with the through hole is provided on one side of the through hole. , the ribs above and below the notch form a pair of splints, a dial gauge is installed in the through hole, the probe of the dial gauge is located on one side of the positioning column, and the two horizontal positioning columns and the probe of the dial gauge are on the circumference The upper and lower ribs are connected by bolts. The invention can eliminate the influence of personnel factors on the detection, and accurately determine whether the product to be tested is qualified.

Description

technical field [0001] The invention relates to an outer diameter measuring device, in particular to an outer diameter measuring device for a slightly elastic piston. Background technique [0002] The piston is regarded as the core part of the oil cylinder and shock absorber. It is particularly important to check whether the dimensions of the piston meet the design requirements. The conventional measuring tool for measuring the outer diameter of the piston is a micrometer for the outer diameter. Because the piston ring on the piston of some products is Composite materials have slight elasticity. When the operator measures, the amount of force will also have a certain impact on the measured data. The measured data can only reflect the outline size of a certain point under test, and it is difficult to accurately determine whether the product under test is qualified. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned sh...
