Clamp for spline shaft fork lug hole boring

Abstract

The invention discloses a clamp for spline shaft fork lug hole boring, and relates to a clamp for spline shaft fork lug hole boring in the automatic machining process to solve the problems that in automatic machining, datum transformation is frequent, and the production efficiency is influenced due to excessive manual participation. In the production process, a workpiece is placed on a workpiece supporting plate, an oil cylinder moves and drives a sliding tip so that the sliding tip and a fixed tip can jointly eject the workpiece. An air cylinder works and drives a V-shaped block to move to fix the workpiece and prevent the workpiece from rotating. The fixed tip and the sliding tip are arranged in the opposite directions and are coaxial. The axes of the fixed tip and the sliding tip are perpendicular to a spindle of a machine tool. According to the clamp for spline shaft fork lug hole boring, a center hole of the workpiece serves as a positioning datum, the clamp can be used for machining of lug hole boring of spline shaft forks of various types, datum transformation and manual participation are reduced, and unnecessary machining on the workpiece due to the positioning and clamping problems is omitted.

Problems solved by technology

At present, in the process of machine tool processing of spline shaft fork, a positioning table is pre-processed on the spline shaft fork, and the positioning table on the spline shaft fork is used to cooperate with the positioning plate on the fixture to carry out boring ear hole processing. The specific operation It is to put the spline shaft fork into the positioning plate of the fixture, make the inner hole of the positioning plate cooperate with the positioning platform of the spline shaft fork, and then manually move the V-shaped block tightening device on the fixture to make it fit and tighten with the spline shaft fork, Use the jacking screw to tighten the spline shaft fork through the V-shaped block tightening device to prevent the workpiece from loosening and causing errors in the process of boring ear holes, which makes the workpiece unable to be processed continuously by the machine tool and affects the processing efficiency.

In this clamping method, the positioning table of the spline shaft fork and the inner hole of the positioning plate adopt a small clearance, and it is difficult to clamp the spline shaft fork. If the size of the positioning table is too small, the clamping will be too loose, and the position of the ear hole will It is difficult to guarantee the accuracy of the positioning table. If the size of the positioning table is too large, the spline shaft fork cannot be clamped, so the quality of the workpiece after processing cannot be satisfactory, and the parts need to be pressed and fixed manually many times during the processing process. These All will lead to a lot of time consumption, resulting in long parts processing time and affecting production efficiency

Moreover, some new types of spline shaft forks do not have pre-processing positioning tables. These workpieces cannot match the current boring lug hole fixtures and need to be processed separately, which is more time-consuming and labor-intensive.

The above problems make the processing of the spline shaft fork not suitable for automatic production lines, the processing efficiency is low, and it cannot meet the current processing requirements
