Indexing machining system for long-barrel-shaped workpiece

Abstract

The invention discloses an indexing machining system for a long-barrel-shaped workpiece. The indexing machining system comprises a lathe bed, a chuck mechanism, a positioning assembly, a horizontally-arranged indexing center, a mandrel and a tail center; an indexing driving device capable of moving transversely, a tailstock and a supporting device are arranged on the lathe bed, the indexing driving device is in driving connection with the indexing center, the tail center is fixedly arranged on the tailstock, and the indexing center is in transmission connection with the mandrel through the chuck mechanism. According to the indexing machining system for the long-barrel-shaped workpiece, radial positioning of the mandrel is completed through cooperation of the supporting device, the influence of the gravity of the mandrel and the long-barrel-shaped workpiece on indexing positioning is eliminated under the supporting effect of the supporting device, the indexing center and the tail center abut against one end of the mandrel correspondingly under cooperation of the indexing center and the tail center, the positioning deviation of the mandrel is greatly reduced, the mandrel, the indexing center and the tail center are located at the same coaxiality, axial positioning of the mandrel and the workpiece is achieved more accurately, and it is guaranteed that the machining position of a laser is accurate.

Description

technical field [0001] The invention relates to the technical field of component processing, in particular to an indexing processing system for long cylindrical workpieces. Background technique [0002] Laser processing has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, and smooth incision. Laser cutting is also used in the indexing processing of long cylindrical workpieces. During indexing processing, the long cylindrical workpiece is generally clamped by the indexing chuck and the tip of the tail. At the other end of the mandrel, the indexer on the indexing chuck divides the angle of the circumference of the long cylindrical workpiece into equal parts according to the set parameters. The indexing chuck drives the mandrel and the workpiece to rotate an angle, and the laser head performs a local inspection of the workpiece. cutting processing. The existing indexing chucks are mainly in the form of three-jaw chucks or four-...

AI Technical Summary

Problems solved by technology

The existing indexing chucks are mainly in the form of three-jaw chucks or four-jaw chucks. On the one hand, the jaws of the indexing chucks will jointly cause a certain clamping deformation on the mandrel. The mass is heavy, and they will form a vertical downward component force. After the mandrel is clamped by the indexing chuck, there will be a certain offset, which will affect the coaxiality of the mandrel, the indexing chuck and the tip of the tail. , the mandrel has a large amount of circular runout, which affects the accuracy of the machining position
