Bidirectional self-prove rated force measuring device

Abstract

The invention discloses a pressure testing machine, in particular, a bidirectional self-prove rated force measuring device. The bidirectional self-prove rated force measuring device comprises a rack (3); the rack is provided with a motor (2) and a transmission rod (6) which are connected with each other; the rack is provided with a fixture (7) located between the front part and rear part of the transmission rod; the transmission rod is provided with a left slider (3) and a right slider (4) which are correspondingly installed at two sides of the fixture; the left slider and the right slider are correspondingly connected with one end of a left pressure adjuster (10) and one end of a right pressure adjuster (5) respectively; and the left pressure adjuster and the right pressure adjuster are correspondingly installed on the left slider and the right slider and are both electrically connected with a microcomputer controller (1). According to the bidirectional self-prove rated force measuring device of the invention, with the left pressure adjuster and the right pressure adjuster adopted, bidirectional self-prove pressure impact tests can be performed at opposite directions, so that measurement results can be verified by each other. The bidirectional self-prove rated force measuring device has the advantages of simple structure, low workpiece loss, accurate and accurate result feedback and the like.

Description

technical field [0001] The invention relates to a testing machine, in particular to a force measuring device. Background technique [0002] The workpiece strength test is an important process after the workpiece is processed, mainly to test the qualification of the workpiece, so as to judge the feasibility of the original production plan and technology. For testing the strength of the workpiece, the existing press can only measure the maximum strength value after destroying the workpiece, so that the damage of the press to the workpiece under test makes the workpiece unable to be effectively repaired and reused after the test. For some special workpieces, such as fixed seat components, the prior art often ignores the necessity of bidirectional testing in workpiece testing, so that the accuracy of workpiece testing often has certain doubts and instability. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming...
