Brake piston hardness on-line measuring instrument

Abstract

The invention discloses a brake piston hardness on-line measuring instrument. The brake piston hardness on-line measuring instrument comprises a base, a fixing rod is fixedly arranged on the end face of the top of the base, a working box used for detecting hardness is fixedly arranged on the end face of the top of the fixing rod, and a lifting block sliding groove which is provided with an upward opening and used for clamping brake pistons is formed in the end face of the top of the base. Push plate cavities which are in bilateral symmetry and are used for spraying grease are formed in the inner wall of the left side of the lifting block sliding groove. Rapid hardness detection of the brake pistons is achieved, 100% hardness detection for the pistons can be completed, the percent of pass of products is guaranteed, the detection degree of the products is increased, and the failure risk of the products is reduced. Grease is sprayed to the surface of the qualified pistons while detection is completed, and subsequent brake piston assembling is facilitated. Meanwhile, grease is not sprayed to the unqualified brake pistons, so that an operator can quickly distinguish qualified products from unqualified products, mistaken taking is avoided, and meanwhile production waste is reduced.

Description

technical field [0001] The invention relates to the related field of measuring instruments, in particular to an online measuring instrument for the hardness of a brake piston. Background technique [0002] Measuring instruments are third-party standards needed to measure certain attribute values ​​of the target. At this stage, the detection of brake pistons and the hardness of its key parameters are mostly random inspections due to the limitations of measuring instruments, and the detection degree is low. Unavoidable Defective products flow into the market, causing adverse effects. At the same time, after the completion of the test, the measuring instrument for testing the hardness of the brake piston only gives a report, and does not directly indicate which piston is qualified or unqualified. It is easy to cause workers to forget to mark and lead to qualified products and Confusion of non-conforming products. Contents of the invention [0003] The technical problem to be...
