AI Technical Summary
The existing electrical conduit has poor stability on the impact testing machine, which means that the impact force of the hammer cannot be fully applied to the conduit, affecting the accuracy of the test.
A stable electrical conduit impact testing machine was designed. By setting up structures such as arc grooves, bidirectional lead screws, clamping plates and locking threaded holes, the electrical conduit can be limited and fixed. The height of the hammer can be adjusted by lifting plates and L-shaped hook plates to ensure that the impact force of the hammer is effectively applied to the conduit.
This improves the stability of electrical conduit in impact tests, ensures the effective application of the impact force of the hammer, and enhances the accuracy of test detection.
