Quick keyway positioning and clamping device

Abstract

The invention discloses a quick keyway positioning and clamping device. The quick keyway positioning and clamping device is provided with a milling machine table, three T-shaped grooves are transversely arranged on the upper portion, the middle portion and the lower portion of the milling machine table respectively, a right ejection pin seat is mounted on the right side of the milling machine table via T-shaped bolts and the T-shaped grooves on the milling machine table, a claw ejection pin is arranged on the right ejection pin seat, a plurality of through holes are formed in the upper portion, the middle portion and the lower portion of a base plate and correspond to the three T-shaped grooves on the milling machine table, the T-shaped bolts penetrate the through holes of the base plate and the T-shaped grooves on the milling machine table to mount the base plate on the left side of the milling machine table, positioning blocks are arranged on the T-shaped bolt in the middle of the base plate, a left ejection pin seat is arranged on the base plate, a self-pressing telescopic ejection pin is arranged on the left ejection pin seat, and a hand wheel is arranged at the tail end of the self-pressing telescopic ejection pin. The quick keyway positioning and clamping device is simple in structure, convenient and quick to feed and discharge workpieces, high in depth of parallelism and degree of symmetry during shaft keyway processing, and the purpose for convenience, quickness and work efficiency increasing is achieved.

Description

technical field [0001] The invention relates to a shaft processing machine, in particular to a keyway fast positioning and clamping device for machining the outer circular keyway of a camshaft. Background technique [0002] At present, most of the existing keyways for shaft machining are clamped with clamps or three-jaw chucks. Using this method to process keyways for shafts is complicated for the operator, and it is difficult to adjust the parallelism of the workpiece. And symmetry, the upper and lower workpieces are inconvenient, the work efficiency is low, and it is not easy to meet the process requirements. Contents of the invention [0003] The purpose of the present invention is to improve the above disadvantages and provide a keyway fast positioning and clamping device with simple structure, convenient and fast loading and unloading, and high workpiece parallelism and symmetry when machining shaft keyways. [0004] The specific scheme of the present invention is: t...
