AI Technical Summary

Technical Problem

The clamping area of ​​traditional square pipe fittings is limited and cannot provide sufficient clamping force, which causes the pipe fittings to loosen or fall off during the test, affecting the test results and increasing the difficulty of operation.

Method used

A torque test fixture including mounting plate, side plate, fixing frame and adjustment block is designed. The position of the clamp is adjusted through the slide groove and adjustment block, and the spacing of the clamp is adjusted using the spline rod and sleeve to ensure stable clamping of the square pipe fittings.

Benefits of technology

Through this design, the position and spacing of the clamping plates can be adjusted according to the width of the square pipe fitting, which significantly improves the clamping stability of the pipe fittings and ensures the accuracy and safety of the test results.

Abstract

The utility model belongs to the technical field of torsion test fixtures, and particularly relates to a component torsion test fixture which comprises a mounting plate, a transverse sliding groove is formed in the rear portion of the top of the mounting plate, and two adjusting blocks are oppositely arranged in the sliding groove in a sliding mode. Lateral plates which are symmetrical left and right are arranged in front of each adjusting block, a transverse second positive and negative screw rod is rotationally arranged between the two lateral plates, and clamping plates are arranged on external threads on the two sides of the second positive and negative screw rod in a transmission mode respectively. According to the utility model, according to the overall width of the to-be-detected square pipe fitting, the hand rocker drives the first positive and negative screw rod to rotate, so that the left and right clamping plates on the same side are respectively located on the inner and outer side walls of the left and right side edges of one end of the square pipe fitting, and then the turntable drives the second positive and negative screw rod to rotate. And the other second positive and negative screw rod rotates at the same time through the spline rod and the sleeve, so that the distance between the two clamping plates on the same side is adjusted, the inner side wall and the outer side wall of the left side edge and the right side edge of the square pipe fitting are clamped and fixed correspondingly, and the clamping stability of the square pipe fitting is improved.
