Abstract

The invention provides a rotary part pneumatic tensioning device with a shaft positioning function. The rotary part pneumatic tensioning device comprises a main seat body, a workpiece rotating shaft, an oil cylinder end cover, a hydraulic oil rotating joint, an air pressure input and output port, a piston stop sliding block, a chuck pull rod piston, a chuck tensioning spring, a spring chuck and a chuck stop pin, wherein the workpiece rotating shaft is arranged in the main seat body; the workpiece rotating shaft is rotationally connected with the main seat body; one end of the workpiece rotating shaft is provided with the hydraulic oil rotating joint; the chuck pull rod piston is arranged in the workpiece rotating shaft; the piston stop sliding block is arranged at the position, located at one end of the chuck pull rod piston, in the workpiece rotating shaft; the output end of the hydraulic oil rotating joint penetrates through the piston stop sliding block and is led into one end of the chuck pull rod piston; the outer side of the chuck pull rod piston is sleeved with the chuck tensioning spring; the spring chuck is fixed at the end part of the chuck pull rod piston; a workpiece mounting position is arranged at the end part of the spring chuck; and the spring chuck is inserted into the chuck stop pin. According to the device, pneumatic tensioning of the rotary part is facilitated, and accurate and automatic clamping is facilitated.

Description

technical field [0001] The invention relates to the technical field of workpiece production equipment, in particular to a pneumatic tensioning device for rotary parts with shaft positioning. Background technique [0002] For the grinding of the chamfered part of the CBN drill bit blade for oil drilling, the existing devices mostly use chucks or spring chucks for manual clamping, which cannot realize automatic production. [0003] Therefore, it is urgent to design a pneumatic tensioning device for rotary parts with shaft positioning to solve the above-mentioned problems. SUMMARY OF THE INVENTION [0004] The purpose of the invention provided by the present invention is to provide a pneumatic tensioning device for rotary parts with shaft positioning, which is convenient for pneumatic tensioning of rotary parts and facilitates accurate automatic clamping. [0005] In order to achieve the above purpose, the present invention is achieved through the following technical solutio...
