FIG. 1 is a schematic perspective view of the present utility model;
fig. 2 is a plan cross-sectional view of the present utility model.
Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
Referring to fig. 1-2, the present embodiment adopts the following technical scheme: the utility model provides a digit control machine tool trench car tooth exhibition tool bit, including exhibition tool bit body 1, cylinder rack pull rod 2, helical tooth piece 3, slider base 4 and clamp plate 5, install cylinder rack pull rod 2 in the exhibition tool bit body 1, cylinder rack pull rod 2 forms sliding connection with exhibition tool bit body 1, sliding mounting has slider base 4 on the exhibition tool bit body 1, slider base 4 and helical tooth piece 3 fastening connection, helical tooth piece 3 passes through helical tooth meshing with cylinder rack pull rod 2, helical tooth piece 3's bottom contacts with exhibition tool bit body 1, and clamp plate 5 crimping is passed through at helical tooth piece 3's top.
The expanding tool bit body 1 of the specific embodiment is fixed at the front section of a main shaft of a machine tool, the cylindrical rack pull rod 2 is connected with a pull rod penetrating through the center of the main shaft, and then the cylindrical rack pull rod 2 is connected by penetrating through the center of the main shaft through a pull rod. The working principle is as follows: the cylindrical rack pull rod 2 is pulled, the cylindrical rack pull rod 2 is meshed with the helical gear block 3 to drive the helical gear block 3 to move, and the slider base 4 is slidably mounted on the cutter head body 1, so that the cylindrical rack pull rod 2 moves to drive the helical gear block 3 and the slider base 4 to do linear reciprocating motion along the bottom surface of the cutter head body 1 and do vertical motion along the central line of the main shaft, and then the cutter mounted on the slider base 4 is driven to do transverse motion, so that transverse cutting is achieved, and machining of thread cutting and groove cutting of parts is completed.
