Embodiment Construction

[0017] Referring to accompanying drawings 1, 2, 3 and 4, the eccentric shaft processing jig shown in the embodiment of the present invention mainly consists of a bottom plate 2, a V-shaped module 4 fixed on the bottom plate, a limiting groove 7 fixed on one side of the bottom plate, and a pressing plate 5. The pneumatic device 10 is composed of a guide rod 9 fixed on the bottom plate. The pressure plate 5 is connected with the moving parts of the pneumatic device 10 and moves up and down along the guide rod 9 . When operating, put the workpiece on the V-shaped module 4, adjust the eccentric shaft of the front section of the workpiece to face the limit groove 7 on the limit groove module, push it lightly so that it just inserts into the groove, and at the same time, the end face is close to the limit groove The end face realizes the axial positioning of the workpiece. Press the button of the pneumatic device, and the pressure head, under the action of the moving parts of the pne...

Abstract

The invention relates to an eccentric shaft machining clamp which is mainly composed of a base plate, a shaft sleeve positioning device fixed on the base plate and a pressing plate. The eccentric shaft machining clamp is characterized by further comprising a pneumatic device and a guide rod fixed on the base plate. The pressing plate is connected with a moving part of the pneumatic device and moves up and down along the guide rod. When the eccentric shaft machining clamp is operated, a workpiece is placed in the shaft sleeve positioning device on the base plate and axial positioning of the workpiece is achieved. A pneumatic device button is pressed and a pressing head presses till a workpiece rod body portion along the guide rod through the action of the moving part of the pneumatic device. Circumferential pressing and positioning of the workpiece are achieved, and the whole pressing process is easy to operate, short in time, efficient, good in universality as workpieces of the same series can be positioned and clamped through the clamp and capable of greatly meeting the production requirement.

Description

technical field [0001] The invention relates to a jig for processing an eccentric shaft, which belongs to the technical field of mechanical processing. Background technique [0002] In the prior art, the eccentric shaft processing fixture is mainly composed of a base plate, a shaft sleeve positioning device fixed on the base plate, a screw fixed on the base plate, a pressure plate, a handle, and other components. It is positioned on the shaft sleeve positioning device fixed on the bottom plate to realize the axial positioning of the workpiece, and the handle is pulled to make the pressure plate move down along the screw rod until the workpiece is pressed to realize the circumferential compression and positioning of the workpiece. The deficiencies of the existing technology: long workpiece positioning time, low work efficiency; cumbersome operation process, relatively high skill requirements for employees; complex fixture structure, relatively heavy, high manufacturing cost, ...
