[0026] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0027] Embodiment:

[0028] See Figures 1 - 3 , an alloy milling cutter processing device, including a carrier 1, clamping plates 2, a pressing ring 3 and spring pieces 4. Specifically, the inside of the carrier 1 is a hollow structure, and there is a tooling channel 5 penetrating from the top to the bottom of the carrier 1, and the tooling channel 5 is a circular structure.

[0029] There are several clamping plates 2, and all the clamping plates 2 are arranged inside the carrier 1 and are evenly distributed around the circumference of the tooling channel 5. Among them, one end of the clamping plate 2 is wider than the other end, so that the clamping plate 2 is a structure similar to a triangle. Each clamping plate 2 has a support rod 7 on each side. One end of the support rod 7 is fixedly arranged at the top of the carrier 1, and the wider end of the clamping plate 2 is close to the top of the carrier 1, and the smaller end of the clamping plate 2 is rotatably connected to the two support rods 7.

[0030] In addition, it is assumed that there are N clamping plates 2, N≥3, and the included angle between the surfaces of adjacent two clamping plates 2 is 360° / N. At the same time, a spring piece 4 is arranged between the support rod 7 and the clamping plate 2. The spring piece 4 is a V-shaped structure, and the spring piece 4 has the function of driving the wider end of the clamping plate 2 to move away from the tooling channel 5.

[0031] The pressing ring 3 is a ring-shaped structure, and the pressing ring 3 is movably arranged inside the carrier 1 and can move closer to or away from the top of the carrier 1 inside the carrier 1. Among them, the pressing ring 3 is sleeved outside all the clamping plates 2 and is always in sliding contact with the outer side of the clamping plates 2. Generally, the outer side of the clamping plates 2 is an arc surface, so as to avoid the wear of the inner wall of the pressing ring 3 by the sharp corners.

[0032] In this embodiment, a spring piece 4 is provided on each side of each clamping plate 2. A tooling channel 5 is arranged on the carrier 1 so that the alloy milling cutter to be clamped can be placed in the tooling channel 5. Then, the pressing ring 3 moves up and down in the carrier 1, so that by means of the pressing action of the pressing ring 3 on all the clamping plates 2, the tops of all the pressing plates move closer to or away from each other, thereby realizing the clamping or loosening of the alloy milling cutter.

[0033] This technical solution provides a new clamping tooling, which can provide various clamping tooling options for the processing device.

[0034] In one specific embodiment:

[0035] The pressing ring 3 is provided with a plurality of through holes, and a guide rod 6 is slidably matched in each through hole. The top end of the guide rod 6 is fixedly connected to the top of the carrier 1, and the bottom end of the guide rod 6 is fixedly connected to the bottom of the carrier 1.

[0036] By arranging the guide rod 6, the pressing ring 3 can be prevented from rotating in the carrier 1.

[0037] In another specific embodiment:

[0038] A cylinder 8 is rotatably arranged in the carrier 1. The cylinder 8 is a hollow cylinder and is sleeved outside the pressing ring 3. The outer peripheral surface of the pressing ring 3 has an external thread, and the inside of the cylinder 8 has an internal thread, which is matched with the external thread outside the pressing ring 3. Thus, by rotating the cylinder 8, the purpose of driving the pressing ring 3 to move on the guide rod 6 can be achieved.

[0039] In another specific embodiment:

[0040] A toothed ring is sleeved on the outer peripheral surface of the cylinder 8. Among them, a first-stage gear 9 is meshed with the toothed ring. The first-stage gear 9 is fixedly arranged on a main shaft 11. The bottom end of the main shaft 11 is rotatably connected to the bottom of the carrier 1, and the top end of the main shaft 11 passes through the top of the carrier 1. And a connection hole is arranged at the top end of the main shaft 11, and the connection hole is a countersunk hole with an internal hexagon.

[0041] In this embodiment, the rotation of the cylinder 8 is driven by the meshing of the toothed ring and the first-stage gear 9, and the first-stage gear 9 is fixedly arranged on the main shaft 11. The main shaft 11 and the first-stage gear 9 can be driven to mesh by inserting a hexagon wrench into the connection hole.

[0042] In another specific embodiment:

[0043] A secondary gear 10 meshes with a primary gear 9. The number of teeth of the secondary gear 10 is less than that of the primary gear 9. The secondary gear 10 is fixedly arranged on a secondary shaft 12. One end of the secondary shaft 12 is fixedly arranged at the bottom of the carrier 1, and the other end of the secondary shaft 12 passes through the top of the carrier 1, and a driving hole identical to the connection hole is arranged at this end of the secondary shaft 12.

[0044] In this embodiment, by driving the primary gear 9 to rotate through the main shaft 11, the cylinder 8 can be quickly driven to rotate, so as to quickly pre-clamp the alloy milling cutter. Then, by rotating the secondary shaft 12 and driving the primary gear 9 and the cylinder 8 to rotate through the secondary gear 10, the alloy milling cutter can be locked.

[0045] Preferably, the ratio of the number of teeth of the primary gear 9 to the number of teeth of the secondary gear 10 is greater than 2:1.

[0046] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
