Part clamping device

Abstract

The invention discloses a part clamping device. The part clamping device comprises a rack, a main clamping device and an auxiliary clamping device, wherein the main clamping device is arranged at the front end of the rack, and the auxiliary clamping device is correspondingly arranged at the rear end of the rack. The main clamping device comprises a main mounting frame, a mounting plate and a plurality of gear motors, wherein the mounting plate is arranged on one side of the main mounting frame, and the gear motors are fixed to the mounting plate through a mounting bracket. The output ends of all the gear motors are connected with a driving shaft through a synchronous belt transmission mechanism respectively. A hydraulic cylinder device used for driving the driving shaft to move forwards and backwards is arranged outside the driving shaft. A clamping block is arranged at the output end of the driving shaft. The auxiliary clamping device comprises an auxiliary mounting frame and a driven hollow shaft arranged on the auxiliary mounting frame. The driving shaft and the driven hollow shaft correspond to each other and are on the same axis. The part clamping device can clamp a workpiece and enable the workpiece to rotate, and therefore geometric errors caused by immobilization of the workpiece during drilling can be eliminated.

Description

technical field [0001] The invention relates to a component clamping device. Background technique [0002] When traditional parts are drilled, because the parts are fixed on the worktable, the parts cannot rotate, and only the main movement and feed movement can be performed by the drill bit. During the drilling process, it is easy to cause the eccentricity of the parts, especially when performing deep hole drilling, it is difficult to guarantee the straightness of the axis of the hole and the cylindricity of the hole, and it is difficult to meet the technical requirements. , because the drill bit is too long, it is easy to deform under the action of cutting force, resulting in too large geometric tolerance of the hole, which cannot meet the technical requirements. Contents of the invention [0003] The object of the present invention is to provide a part clamping device for the defects of the prior art. [0004] In order to achieve the above object, the present inventio...
