Rotary connection and internal wire bending test device

Abstract

The invention relates to a rotation connection and internal wire bending testing device which comprises a programmable logic controller and a motor which are installed in a casing and a fixing clamp located on the outside of the casing, installed on a motor output shaft and used for fixing a device to be tested. According to a testing requirement, the programmable logic controller is connected with the motor to control rotating speed, rotating angle and rotating times of the motor. A human-computer interface or a computer is utilized to conduct monitoring to achieve parameter selection, parameter modification and starting and stopping control of the device. The device has the advantage that control functions required by all detection terms can be achieved on only one device. By means of the device, manual operation is not required in power supply and signal transmission of the device to be tested, and the clamp can be adjusted to be applicable to fixing and testing of devices to be tested and in various shapes. Control functions apart from the standard terms can be achieved by modifying the control parameters. Therefore, the operation difficulty is reduced, test efficiency is improved, and labor intensity of testing engineers is reduced.

AI Technical Summary

Problems solved by technology

Manual testing or using a single-function mechanical electric test device has the following disadvantages: each mechanical electric test device can only meet the technical requirements of a single standard item, and has a single function; the power supply and signal transmission of the device under test need manual operation; Unable to meet the fixation of various geometric appearance appliances, thus increasing the work intensity, increasing the difficulty of operation and reducing work efficiency
