Washing machine cover impact test device

Abstract

The invention discloses an impact testing apparatus for upper covers of washing machines. The impact testing apparatus comprises two cylindrical guide rails, a small fixed pulley support, an upper cylindrical guide rail supporting frame, a guide protective mechanism, an impact hammer hoisting mechanism, an impact hammer body, a brake handle, a supporting frame, a front rubber impact head, a worm and gear speed reducer, a steel wire rope sheave, a lifting handle, a lower cylindrical guide rail supporting frame, a large fixed pulley support, a large fixed pulley, a traction steel wire rope, a small fixed pulley and a special gauge. An impact testing assembly with the front rubber impact head impacts an upper cover of a household electric washing machine in a free falling mode, and load is filled into the household electric washing machine from the top of the household electric washing machine. The impact testing apparatus for the upper covers of the washing machines has the advantages that impact tests can be conveniently performed on the upper covers of the washing machines, the impact testing apparatus can be operated conveniently and quickly, the accuracy and the safety of the tests for the upper covers of the washing machines can be improved, the integral cost of the tests can be lowered, and the like.

By setting the test special weight on the small permanent magnet lifter, operating the perma...

AI Technical Summary

Problems solved by technology

This kind of structure using small permanent magnetic lifter and manual lifting hoist requires special equipment such as permanent magnetic lifter and manual lifting hoist. The overall structure is heavy and the test cost is high.

This test device is not equipped with a protective mechanism, and the weight does not have a weight adjustment function. There is no special measuring tool for measuring the test height, which has disadvantages such as poor safety and accuracy.
