[0010] Preferably, a slot is provided at the junction of the non-return portion and the retention member.

[0011] Preferably, the outer side surface of the anti-return portion is an inclined surface;

[0012] It also includes a movable ring arranged outside the retention member, and the movable ring is slidably connected to the inclined surface of the non-return portion so that the multiple non-return portions are brought closer to the axis.

[0013] Preferably, V-shaped elastic members arranged in a circumferential array are provided between the retention member and the movable ring.

[0014] Preferably, the retaining member is slidably assembled with the knife groove.

[0015] In the above technical scheme, the utility model provides a shockproof machine clamp milling cutter for improving the tool life, which has the following beneficial effects: the machine clamp blade and the shockproof tool rod are cleverly designed to be integrated as a whole, thereby being able to greatly extend the tool life, and the tool change is also convenient, which can increase the tool life by more than 30%.

[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] like Figure 1-3As shown, a vibration-proof machine clamp milling cutter for improving tool life includes an integrally formed tool bar 1 and a tool holder 2, and a tool slot 21 arranged in a circumferential array is provided on the side of the tool holder 2. In the embodiment, the hexagonal nut locking member 4 includes a nut 41 and a retention member 42 arranged on the tool slot 21, and the outer wall of the retention member 42 is provided with an extension 43 arranged in a circumferential array, and a non-return portion 431 is provided on the extension 43. The nut 41 is threadedly assembled with the retention member 42, and the diamond blade 3 is plugged with the non-return portion 431. Then the diamond blade 3 is fixed in the blade slot 21 through the nut 41, and the retention member 42 is located in the boring hole of the diamond blade 3.

[0024] Furthermore, as the nut 41 pushes the diamond blade 3, it squeezes the retaining member 42 and the movable ring 44 fixedly installed near the inner wall of the knife groove 21 (the retaining member 42 is slidably assembled with the knife groove 21), so that the V-shaped elastic member 5 arranged in a circumferential array between the two is compressed and deformed.

[0025] Combination Figure 3 It can be seen that the movable ring 44 includes a vertical portion, which is tangent to the outer inclined surface of the non-return portion 431, thereby pushing the multiple non-return portions 431 to move closer to the axis, so that a groove 432 is provided at the junction of the non-return portion 431 and the retention member 42 to be clamped and fixed with the diamond bit 3.

[0026] Furthermore, the diamond blade particles 3 in the blade groove 21 are arranged tilted, and the minimum angle along the clockwise direction is 35°.

[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.
