Pneumatic clamping type ordinary lathe

Abstract

The invention discloses a pneumatic clamping general lathe. The pneumatic clamping general lathe comprises a pneumatic spanner and a pneumatic ejecting device; the pneumatic spanner includes a pneumatic gun drill; a drill bit of the pneumatic gun drill is replaced to a cylindrical first connecting rod; the first connecting rod is connected with a second connecting rod for extending into a spanner head; an arc piece body is arranged at the extension end of the second connecting rod; an arc groove for mounting a spring is formed in the bottom of an extension hole; and when the second connecting rod extends into the spanner head and rotates to a proper position, a spring is compressed, and the arc end of the arc piece body is connected with the end surface of one end, provided with the spring, of the arc groove. The pneumatic ejecting device includes a tail base and a tip; a sleeve is embedded in the tail base; a sealing ring is arranged on the right end surface of the inner wall of the sleeve; the tip is arranged at the tail end of an output shaft of a cylinder; a spiral groove is formed in the inner wall of the sleeve, and gradually extends and expands from the right end of the sleeve to the left end; and multiple laps of grooves are formed in the surface of the output shaft. The lathe can quickly realize clamping of workpieces, and effectively controls the clamping strength of the workpieces.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a common lathe. Background technique [0002] Lathes play a pivotal role in metal cutting. Commonly used lathes are classified according to their degree of automation. There are two main types, one is CNC lathes controlled by servo system, and the other is ordinary lathes, whether it is CNC lathes or ordinary lathes , are set as figure 1 The shown spindle box a, chuck S1, machine tool guide rail b, and tailstock 1 with top system c, usually the head of the lathe is equipped with the above-mentioned chuck S1, the end of the bed is equipped with a tailstock 1, and the tailstock 1 is equipped with There is a top system c. The top c1 in the top system c is set parallel to the guide rail b of the machine tool. The top and the tailstock 1 are threadedly connected or the screw is directly used and its end is processed into a conical point as the top c1. There is a handwh...

Problems solved by technology

This method of installing and adjusting the tightness of the chuck has been used for decades. However, in the process of use, on the one hand, due to manual pulling, it is time-consuming, laborious and inefficient; on the other hand, it is also the biggest defect here. That is, the strength of pulling the chuck S1 cannot be grasped manually, which will cause the workpiece e to be over-clamped and deformed, or the axis of the clamping will be shifted, resulting in a huge error in machining accuracy
