Abstract

The invention discloses a five-claw elastic pneumatic clamping device for a turning and grinding machine tool. The device comprises a piston body, a cylinder assembly, a clamping assembly and a compressed spring assembly, wherein a piston rod is connected to the piston body in a sliding mode; the cylinder assembly comprises a self-locking cylinder shaft, a cylinder body and a cylinder cover, the self-locking cylinder shaft, the cylinder body and the cylinder cover are all arranged inside the piston body, one end of the cylinder body is fixed to one end of the self-locking cylinder shaft, and the cylinder cover is fixed to the other end of the cylinder body; the clamping assembly comprises a special-shaped five-claw part and a V-shaped locating block, one side wall of the V-shaped locatingblock is arranged at the other end of the self-locking cylinder shaft, the special-shaped five-claw part is arranged on the other side wall of the V-shaped locating block, and the special-shaped five-claw part, the V-shaped locating block and the self-locking cylinder shaft are sequentially connected through bolts; and the compressed spring assembly comprises a compressed spring seat, a compressedspring locating sleeve and a rectangular compressed spring, the compressed spring seat is arranged opposite to the compressed spring locating sleeve, and the rectangular compressed spring is arrangedis arranged between the compressed spring seat and the compressed spring locating sleeve. The clamping device is good in structure compactness, good in clamping consistency, safe and reliable in clamping and high in adjustment precision controllability.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool manufacturing, and more specifically relates to a five-claw elastic pneumatic clamping device for a turning and grinding machine tool. Background technique [0002] At present, the internal and external profiles of the CVT transmission wheel of high-end cars and the ballway grooves are clamped once on the special machine tool for turning and grinding. The workpiece clamping device is mostly processed by three-jaw or four-jaw chucks. Due to the large processing batch, there are few clamping points. , The fixture wears quickly, which leads to large deviations in the accuracy of the processed parts. [0003] Therefore, it is an urgent problem to be solved by those skilled in the art to provide a five-jaw elastic pneumatic clamping device for turning and grinding machine tools with strong adjustment accuracy, controllability and good clamping consistency.
