Comprehensive test device for pliers and nippers

Abstract

The invention discloses a comprehensive test device for a pair of pliers and a pair of nippers, and belongs to the technical fields of product quality detection and metering calibration testing. The device comprises a cabinet, wherein a working platform is arranged at the top of the cabinet; a pliers fixing mechanism, a pliers pressure mechanism and a pliers torsion mechanism are assembled on theworking platform; a bending-resistant test piece clamping component, a pliers rotating shaft clamping component and a pliers handle supporting component of the pliers fixing mechanism and the workingplatform are disassembled and assembled quickly, the distance between the three components can be flexibly adjusted to be adapted to tests of pliers with different types and specifications, and the three components can be mutually combined and used; and the bending-resistant test piece clamping component, the pliers rotating shaft clamping component and the pliers handle supporting component of the pliers fixing mechanism and the working platform are disassembled and assembled quickly, the distance between the three components can be flexibly adjusted to be adapted to tests of pliers with different types and specifications, and the three components can be mutually combined and used.

Description

technical field [0001] The invention belongs to the technical field of product quality inspection and measurement calibration test, and in particular relates to a comprehensive test device for twisting pliers and cutting pliers. Background technique [0002] For the test of tongs, cutters and torsion cutters, the country has formulated the standard GB / T 6291-2013 "Test methods for torsos and cutters". In this method, in addition to the surface of the pliers, the In addition to specifying test methods such as mouth gap, mouth top gap, clamping surface hardness and cutting edge hardness, it mainly stipulates the test methods of bending strength test, shear performance test and torsion test of pliers. However, there is no such standard in the standard. The specific test devices are specified uniformly. [0003] The patent literature on the pliers test mainly includes: Chinese patent application number CN201810025659.0, which discloses a hydraulic clamp fatigue test bench, and ...

AI Technical Summary

Problems solved by technology

[0002] The national standard GB / T 6291-2013 "Test methods for tongs and shears" has been formulated for the test of tongs, cutters and torsion cutters. In this method, in addition to the surface of the pliers, the In addition to specifying test methods such as mouth gap, mouth top gap, clamping surface hardness and cutting edge hardness, it mainly stipulates the test methods of bending strength test, shear performance test and torsion test of pliers. However, the standard does not specify Specific test equipment to make unified regulations

[0003] The patent literature on the pliers test mainly includes: Chinese patent application number CN201810025659.0, which discloses a hydraulic clamp fatigue test bench, and Chinese patent application number CN201510371340.X, which discloses a main body frame for a clamp test bench , Chinese Patent Application No. CN201821697434.1, which discloses a simple test bench for multi-functional detection of calipers, etc. None of the above-mentioned disclosed technical solutions is aimed at the national standard GB / T 6291-2013 "Test Methods for Clamps and Cutters" Design is required, so there is still a lack of special test and testing equipment for bending strength tests, shear performance tests and torsion tests on pliers. The quality inspection and calibration test efficiency of pliers is low, which affects work efficiency.
