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.

Description
