Description

Ball pin pinhole position correction and torque detection device Technical Field The utility model relates to the technical field of ball pin processing equipment, in particular to a ball pin hole position correcting and torque detecting device. Background In an automobile mechanical transmission system, a ball pin is used as a key connecting part, and the precision of the position of a pin hole directly influences the motion performance and the reliability of a transmission mechanism. In the traditional production process, the pin pull rod is easy to deviate from the pin hole axis due to stress deformation or assembly error after processing and assembly, so that the problems of motion interference, abnormal abrasion and the like are caused, in addition, the rotation torque performance of the pin assembly is one of the core indexes of quality evaluation, and accurate detection is required after assembly is completed, so that the pin assembly meets the design load requirement. The correction of the pin hole position of the ball pin in the industry mostly adopts a manual knocking or simple clamp positioning mode, and has the obvious defects that firstly, the traditional clamp lacks dynamic clamping capability and can only realize unidirectional fixation, concentric constraint is difficult to be implemented on the ball pin pull rod, secondary deformation is generated in the correction process due to uneven clamping force distribution, secondly, the correction operation and torque detection are usually carried out step by step, workpieces are required to be repeatedly disassembled and transferred to different equipment, the efficiency is low, and human errors are easy to be introduced in repeated clamping, and the measurement consistency is affected. In addition, the existing torque detection device is designed in a split type, a driving mechanism and a sensor are independently arranged, and the problems of long transmission chain and insufficient structural rigidity exist. When in detection, the angle adjustment is needed to be carried out by manual operation, and the collaborative operation of correction and detection is difficult to realize. In addition, manual locking structure is generally adopted in the clamping unit height adjustment of traditional equipment, and complex operation and positioning accuracy are limited by manual experience, can't adapt to the quick switch demand of different specification ball pin subassemblies.
