High-safety lathe for workpiece machining

Abstract

The invention relates to a high-safety lathe for workpiece machining. The high-safety lathe comprises a machine tool and a feed rest, and the feed rest is movably connected to the top of the machine tool. The high-safety lathe further comprises a fixing mechanism and an anti-collision protection mechanism. The fixing mechanism comprises a machine body, a driving shaft, a clamping jaw and a shaft sleeve, the machine body is arranged at one end, away from the feed rest, of the top of the machine tool, the driving shaft is horizontally and rotatably connected to the side, close to the feed rest, of the machine body, the clamping jaw is arranged at the end, away from the machine body, of the driving shaft, the driving shaft is sleeved with the shaft sleeve, and the end, close to the machine body, of the shaft sleeve is fixedly connected with the machine body. The anti-collision protection mechanism comprises a protection cover, an induction assembly and a controller, the protection cover is arranged at the end, away from the machine body, of the shaft sleeve, the protection cover covers the peripheral side of the clamping jaw, the induction assembly is arranged on the protection cover and electrically connected with the controller, and the controller is used for controlling the feed rest to move. The high-safety lathe has the effect of improving the safety during working of the lathe.

Description

technical field [0001] The present application relates to the technical field of lathes, in particular to a high-safety lathe for workpiece processing. Background technique [0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Parts with higher precision requirements and finer surface roughness requirements generally require final processing on machine tools. In the general workpiece processing process, the workpiece is fixed by the workpiece clamping mechanism on the lathe and driven to rotate at high speed, and the tool holder drives the tool to move to complete the machining operation on the workpiece. [0003] The Chinese invention patent with the application number of 201410290242.9 discloses a lathe, which includes a vehicle body, a headstock, a tailstock and a tool rest. At the rear end of the vehicle body, the tool rest is movably arranged in the middle of the vehicle body, wherein, the front of the vehicle is provided wit...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the process of processing the workpiece, when the workpiece is processed by the high-speed rotating workpiece through the tool rest to drive the tool to move, when the staff causes the tool to feed due to misoperation or misoperation If the distance is too large, after the tool collides with the chuck, the chuck will continue to rotate at high speed, which will cause damage to the lathe. In severe cases, the tool will break and splash, threatening the safety of the workers.
