[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses an indexable machine clamp roughing and fine boring composite forming cutter.

[0024] Reference Figure 1-3 , a indexable machine clamp roughing and fine boring composite forming tool, comprising a handle 2 and a cutter head 1, the cutter head 1 is fixedly arranged at the lower end of the handle 2, the cutter head 1 and the handle 2 are integrally formed, and the connection strength of the cutter head 1 and the handle 2 is improved. Both sides of the inside of the cutter head 1 are provided with mounting grooves, and a blade 5 is clamped on the inner side of the mounting groove. A U-shaped rod 4 is arranged between the two blades 5, and mounting rods 7 are fixedly arranged at both ends of the U-shaped rod 4. A mounting hole is opened in the middle of the blade 5, and the mounting rod 7 is plugged into the mounting hole. The longitudinal sections of the mounting rod 7 and the mounting hole are both rectangular, and the blade 5 is prevented from rotating relative to the mounting rod 7 as much as possible, so that the blade 5 can be installed more stably. A groove is opened on one side of the mounting groove, and a fixing rod 6 is fixedly arranged on the inner side of the groove. A socket is opened at one end of the mounting rod 7, and one end of the fixing rod 6 is plugged into the socket. A positioning block 3 is fixedly arranged in the middle part of the inner side of the cutter head 1, and the middle end of the U-shaped rod 4 is slidably sleeved on the outer wall of the positioning block 3, and a cavity is opened inside the positioning block 3.

[0025] Reference Figure 1-3 A limiting mechanism for limiting the movement of the U-shaped rod 4 relative to the positioning block 3 is provided inside the cavity. The limiting mechanism includes a slider 9 and a block 11. The two sliders 9 are slidably arranged on both sides of the inside of the cavity. The two blocks 11 are fixedly arranged on the side opposite to each other of the two sliders 9. One end of the two blocks 11 extends to the outside of the cavity. The outer ends of the two blocks 11 are in conflict with the rod wall of the U-shaped rod 4. A spring 10 is fixedly arranged between the two sliders 9 to facilitate the resetting of the slider 9. A limiting rod 8 is fixedly arranged inside the cavity. One end of the two sliders 9 is movably sleeved with the corresponding limiting rod 8, so that the slider 9 can slide stably.

[0026] In the utility model, when in use, the cutter head 1 and the cutter handle 2 are integrally formed and processed, which can improve the processing efficiency of the cutter. The double-blade design can increase the service life of the cutter and reduce the defective rate. When installing the blade 5, the two blades 5 are sleeved on the corresponding mounting rods 7, and then the blades 5 are clamped in the mounting groove so that the fixing rod 6 is inserted into the jack on the side wall of the mounting rod 7. At the same time, the U-shaped rod 4 is sleeved on the outer wall of the positioning block 3. Under the elastic force of the spring 10, one end of the two clamping blocks 11 moves out of the cavity and abuts against the side of the U-shaped rod 4 away from the cutter head 1, thereby completing the installation limit of the two blades 5. The operation is convenient and time-saving and labor-saving.

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
