Problems solved by technology

At present, there are also some lathe tailstocks that have been converted into power-driven tailstocks, but it is generally inconvenient to install and operate, and the drilling cannot automatically break chips; usually such devices do not have a mechanical stop mechanism, and accidents may occur if the operator is negligent.

Abstract

The invention relates to a lathe tailstock power feed unit comprising a power support mounted at the tail of a lathe body. A drive shaft is mounted on a power support. The front end of the drive shaft drives a lathe tailstock hand wheel to rotate. The drive shaft is hollow; a shaft lever capable of moving axially along the drive shaft penetrates the drive shaft; the drive shaft drives the shaft lever to rotate; the front end of the drive shaft drives the lathe tailstock hand wheel to rotate; a chip breaking clutch further provided allows chips to be broken during drilling; a stop mechanism is further provided. The lathe tailstock power feed unit has the advantages that mounting, adjusting and using are convenient, chip breaking can be achieved for machining of materials such as steel, smoothness of drilling and safety of tools and personnel are guaranteed, operational accidents caused by excessive feeding of a tailstock sleeve can be prevented.

Description

technical field [0001] The invention belongs to an ordinary lathe auxiliary device, in particular to a lathe tailstock power feeding device, a chip breaking clutch and a stop mechanism. Background technique [0002] The traditional lathe drilling operation is to install the drill bit on the front end of the tailstock sleeve of the lathe, and the operator turns the handwheel of the tailstock to make the tailstock sleeve push the drill bit forward to drill; this is a common operation method for general-purpose lathes. It is suitable for the processing of many varieties and small quantity. If the lathe processes the same number of workpieces and drills a large amount, the labor intensity of the operator will be very high, and the work efficiency will not be high. Tailstocks with self-powered power have been commonly used in some new lathe products, such as commonly used motor-driven tailstock sleeves; but such products have raised the cost and price of machine tool products, a...
