Abstract

The invention provides a pressure testing device of a tappet body and belongs to the field of detection devices of the tappet bodies. The pressure testing device comprises a base and a dynamometer, wherein the base is provided with a lifting device which is fixedly connected with the dynamometer; the dynamometer is provided with a testing head. The pressure testing device also comprises a fixed sleeve which can be matched with the tappet body, wherein the fixed sleeve is arranged under the testing head; when the lifting device drives the dynamometer to move downwards, the testing head presses the tappet body. The pressure testing device provided by the invention has the advantages that the performance of pressure bearing of the tappet body can be well tested, the structure is simple, the operation is simple and convenient, the testing efficiency is improved, and the price is low, so that the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of tappet body testing devices, in particular to a tappet body pressure testing device. Background technique [0002] At present, in the production process of the tappet body, the quality evaluation of the tappet body after processing generally needs to be tested, and the compression resistance of the tappet body is an important index for evaluating its quality. The existing tappet body pressure test is generally carried out by a pressure detector. Although this pressure detector has high test accuracy, its structure is relatively complicated, the operation is inconvenient, the test efficiency is not high, and the price is high, which increases the production cost. . Contents of the invention [0003] The present invention provides a tappet body pressure testing device, aiming to improve the above problems. [0004] The present invention is achieved like this: [0005] A tappet body pressure testing device, compr...
