Problems solved by technology

[0002] In existing mechanical processing, three-jaw or four-jaw chucks are generally used when processing eccentric parts. Since the center of the workpiece does not coincide with the center of the chuck, it is difficult to clamp the workpiece, the machining accuracy is not easy to guarantee, and the qualified rate of the finished product is low, especially When the eccentricity is large, the scrap rate is higher, so the general three-jaw or four-jaw chuck is not suitable for mass production of eccentric parts

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as Figure 1-Figure 4 As shown, the present invention includes a coupling disc 1, a stop pin 2, a mandrel 3, a clamping bolt 4, a split washer 5, a nut 6, a counterweight 7 and a counterweight 8, and the mandrel 3 is embedded in the coupling disc 1. In the hollow inner cavity, it is fixed with bolts, the clamping bolt 4 is threadedly connected with the mandrel 3, and the position of the coupling disc 1 is adjusted with the split washer 5, and the stop pin 2 is installed on the coupling disc 1 to position the workpiece. 1. In the opposite direction of eccentricity, according to different workpieces, two different counterweights 7 and 8 can be installed to balance the workpiece.

[0016] When the present invention is in use, the connecting plate 1 is fixed on the connecting plate of the lathe spindle with bolts, the inner cavity of ...

Abstract

The invention discloses a device for clamping eccentric parts, which relates to the field of machinery. In the existing mechanical working, when eccentric parts are processed, the operation of clamping the eccentric parts is difficult, the working accuracy is not easy to guarantee, and the qualification rate of finished products is low, therefore, the existing eccentric-part clamp device is not suitable for batch production. The device disclosed by the invention comprises a coupling disk, a mandrel, a clamp bolt, a stop pin, a counter-weight block, an open washer and a nut, wherein the mandrel is embedded in a hollow cavity of the coupling disk, the clamp bolt is in threaded connection with the mandrel, the open washer is used for adjusting the position of the mandrel relative to the coupling disk, the nut is used for fixing the coupling disk, the counter-weight block is used for balancing workpieces, and the stop pin is used for positioning. The device disclosed by the invention is an eccentric-part clamp device with a simple structure and easily-guaranteed working accuracy, and has the advantages of wide application scope, high operating efficiency, simplicity in installation, capability of being applied in batch production, and the like.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a clamp for eccentric parts. Background technique [0002] In existing mechanical processing, three-jaw or four-jaw chucks are generally used when processing eccentric parts. Since the center of the workpiece does not coincide with the center of the chuck, it is difficult to clamp the workpiece, the machining accuracy is not easy to guarantee, and the qualified rate of the finished product is low, especially When the eccentric distance is large, the scrap rate is higher, so the general three-jaw or four-jaw chuck is not suitable for mass production of eccentric parts. Contents of the invention [0003] The purpose of the present invention is to solve various defects in the clamping of eccentric parts, and provide a device with simple structure, easy to ensure machining accuracy and simple installation suitable for mass production. For this reason, the present invention adopts the followi...
