Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a waste chip discharging and recycling mechanism for a numerically controlled lathe. Background Art

[0002] CNC machine tools are automated machining equipment controlled by computer programming. It can accurately control the movement and machining process of the machine tool according to the preset program, and realize various machining processes such as cutting, milling, drilling, grinding, etc. of various metal or non-metal materials. Due to its high precision, high efficiency and high flexibility, CNC machine tools have been widely used in modern manufacturing industries such as aviation, automobiles, mold manufacturing, and electronic equipment. During the metal cutting process, the tool removes the excess material layer on the workpiece, and these removed materials form waste chips. Plastic materials form waste chips under the action of shear slip, while brittle materials form waste chips due to crack expansion. If these waste chips are not cleaned up in time, they will cause pollution to the working environment and affect the health of the operators. At the same time, if the waste chips accumulate inside the machine tool for a long time, they may cause wear on the moving parts of the machine tool and affect the service life of the equipment. For this reason, we propose a waste chip discharge and recovery mechanism for CNC lathes. Utility Model Content

[0029] The moving assembly includes a hinge 14, a main shaft 15, a driven gear 16 and a driving gear 17. A hinge 14 is fixedly provided on the back side of the CNC machine tool 1 corresponding to the side of the main rack 10. The main shaft 15 is rotatably mounted on the upper end of the hinge 14.

The driven gear 16 synchronously drives the auxiliary rack 8 to slide in the CNC machine tool 1 through the rotation of the main shaft 15. The push plate 5 slides backward in the empty slot 4 through the sliding of the auxiliary rack 8. When the push plate 5 slides to fit the inner wall of one side of the empty slot 4, the processing equipment 3 is used to process the workpiece. The workpiece is cut, and the waste chips on the workpiece during the cutting process fall into the empty slot 4 on the CNC machine tool 1 by gravity.
