Auxiliary fixing device for Shaw hardness tester rack with adjustable size

Abstract

The invention discloses an auxiliary fixing device for a Shaw hardness tester rack with the adjustable size. The auxiliary fixing device comprises a base. A guiding groove is formed in the base. A stop block is arranged in the guiding groove. A left sliding block and a right sliding block are arranged on the two sides of the stop block. A first screw is in screw joint with the left sliding block and the right sliding block. The left sliding block is provided with a left adjusting plate, and the right sliding block is provided with a right adjusting plate. Adjusting grooves are formed in the opposite sides of the first adjusting plate and the right adjusting plate. A fixed supporting part is arranged at one end of each adjusting groove, a movable supporting part is arranged at the other end of each adjusting groove, and the movable supporting parts can move along the adjusting grooves. According to the auxiliary fixing device, measurement can be stably conducted, the measurement errors are reduced, the auxiliary fixing device is suitable for columnar components different in size, and the beneficial effects that reliability is good, and the application range is wide are achieved.

Description

Technical field [0001] The invention relates to a fixing device, in particular to an auxiliary fixing device of an adjustable Shore hardness tester stand. Background technique [0002] Many parts of a product must have a certain degree of hardness. Otherwise, the parts may be deformed or have some problems in the assembly before leaving the factory, making the product unable to leave the factory, or after leaving the factory due to a certain zero The parts are not wear-resistant and cannot be used. Therefore, the hardness test of product parts is extremely important in production. [0003] There are two main types of hardness testing: metal and non-metal. Many products need to know the hardness of their parts, such as a mold, if the hardness is not enough, it will wear out quickly; sometimes the hardness of a screw as small as a screw must be known to avoid the thread slipping; a large number of electronic products use plastic It is often necessary to measure the hardness of the...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that when using a Shore hardness tester to measure the hardness of a columnar part with a large aspect ratio, the part is not fixed, resulting in a large error in the test result. The purpose is to provide a size-adjustable Shore hardness tester. Bench auxiliary fixing device to solve the above problems
