This utility model restricts the movement position of the cutter 3 by providing the threaded sleeve hole 206 and the connecting threaded sleeve 303, and prevents the cutter 3 from moving after being fixed.

[0015] Furthermore, the bottom end of the connecting screw sleeve 303 is connected to the cutter 3, and the top threaded groove of the connecting screw sleeve 303 is threaded with a connecting screw 302. The other end of the connecting screw 302 is fixedly connected to the limiting block 301.

[0018] Working principle: This embodiment provides a grooving machine with automatic tool changing function. In use, the grooving machine body 1 with a three-axis drive structure drives the cutter head housing 2 to move, and the cutter head housing 2 drives the cutter 3 to move to perform grooving. When different grooves need to be cut, the grooving machine body 1 moves the cutter 3 to the top of the cutter holder 4. The cutter 3 is inserted into the insertion hole 401. The cylinder 203 is opened, which drives the fixed frame 204 to move downward along the slide 201. The limiting steel ball 205 moves to the groove 202. The limiting steel ball 205 can move outward and no longer limit the limiting block 301. The magnet 402 attracts the cutter 3. The cutter head shell 2 moves upward to disengage the cutter 3, completing the disassembly. Next, move the cutter head housing 2 above the cutter 3 to be replaced. The cutter head housing 2 moves downward and inserts the connecting screw sleeve 303 on the cutter 3 through the screw sleeve hole 205. During insertion, the guide protrusion 304 is guided by the guide groove 207 and the inclined surface 208 and inserted into the guide groove 209 to limit the cutter 3. The limiting block 301 pushes open the two limiting steel balls 205 and moves them into the fixed frame 204. Then, the cylinder 203 drives the fixed frame 204 to reset. The fixed frame 204 drives the limiting steel balls 205 to move upward. The limiting steel balls 205 are squeezed inward by the sliding groove 201 and move to the bottom of the limiting block 301 to limit the limiting block 301, thus completing the replacement of the cutter 3.
