Hydraulic control three-jaw chuck device with function of preventing blockage of iron chips

Abstract

The invention discloses a hydraulically controlled three-jaw chuck device with the function of preventing iron filings from clogging. It includes a disc body and claws. The disc body is provided with a ring shaft and a fan. There are also several air outlet holes on the ring shaft, and the fan and the air outlet holes are connected by conduits. There is also a hydraulic mechanism in the disc body. The hydraulic mechanism is connected to one end of the claw, and the other end of the claw is connected to the ring shaft. Connected, and the claw is located in the through hole of the ring shaft, and the claw is also provided with an anti-slip pad. The present invention adopts the hydraulic control method to realize the clamping of the claws to the workpiece, which is relatively labor-saving and time-saving, and the device can effectively prevent iron filings from entering the inside of the disc body, and can also reduce the surface temperature of the workpiece during processing, prolonging the working life of the workpiece. Tool life.

Description

technical field [0001] The invention relates to a processing tool for mechanical parts, in particular to a hydraulically controlled three-jaw chuck device with the function of preventing iron filings from clogging. Background technique [0002] At present, the three-jaw chuck is an accessory tool for clamping workpieces on machine tools such as lathes and milling machines. Its function is to fix the workpiece to be processed tightly and to position the workpiece. The workpiece is clamped manually, and most of them use a series of operations such as manual fine-tuning with the pressure plate, adjustment bolts and compression bolts, which not only increases the labor intensity of the workers, but also requires a lot of force to clamp the workpiece with the three-jaw chuck. , and often the clamping is not tight enough, it is difficult to ensure uniform clamping force, and the workpiece often produces a lot of iron filings in the process of processing, the traditional three-jaw ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the traditional three-jaw chucks are used to clamp the workpiece manually, which has the disadvantages of time-consuming and laborious in actual work, and the traditional three-jaw chucks all use gear transmission to clamp the workpiece. There is a large gap in the structure of the claw adjustment. In the process of processing, the iron filings sometimes enter the structural gap, causing the claw to be stuck. The purpose is to provide an anti-iron The hydraulically controlled three-jaw chuck device with chip blocking function solves the problem that the three-jaw chuck is easy to enter the iron filings and get stuck and the method of gear transmission clamping is laborious.
