[0045] Compared with the prior art, the rim side hole rotary processing tooling provided in this embodiment is provided with a base bracket 1, and the base bracket 1 is used to be fixedly installed on a machine tool. A front support frame 3 and a rear support frame 2 are installed on the base bracket 1 along a first direction, and two front support rollers 31 are rotatably arranged on the front support frame 3. Two rear support rollers 21 are rotatably arranged on the rear support frame 2, and the two front support rollers 31 and the two rear support rollers 21 form a placement position for placing the rim 11. At the same time, the front support rollers 31 and the rear support rollers 21 are both arranged to be tilted upward. When the rim 11 is placed between the front support frame 3 and the rear support frame 2, the axis of the rim 11 is arranged at an angle to the horizontal direction. Thereby, the axis of the ventilation and heat dissipation hole 112 to be processed on the rim 11 is arranged in the vertical direction, and the processing of the ventilation and heat dissipation hole 112 can be completed by using a vertical processing machine tool or a drilling machine. At the same time, the rim 11 can be rotated to adjust the processing position of the holes. After the rim 11 is rotated, multiple ventilation and heat dissipation holes 112 can be processed, which is easy to operate and effectively improves the processing efficiency of the ventilation and heat dissipation holes 112 on the rim 11.

[0047] Preferably, in this embodiment, a guide sleeve 8 is also installed on the base bracket 1, and when the rim 11 is placed on the base bracket 1, the axis of the guide sleeve 8 coincides with the axis of the heat dissipation hole to be processed. The guide sleeve 8 is used to guide the drill bit, thereby ensuring the stability of the drill bit position during the drilling process.

[0048] Specifically, in this embodiment, a mounting plate is installed on the top of the base bracket 1, and the position of the mounting plate on the base bracket 1 has the freedom to be adjusted in the horizontal direction.

[0050] Specifically, in this embodiment, the hinge shafts of the front support frame 3 and the rear support frame 2 on the base support 1 are arranged in parallel and spaced apart. And the axis of the hinge shaft of the front support frame 3 on the base support 1 and the axis of the front support roller 31 always remain perpendicular to each other.

[0051] In some embodiments, the front support frame 3 and the rear support frame 2 can be used as follows: Figure 2 See the structure shown. Figure 2, a flip assembly 5 for adjusting the tilt angle of the front support frame 3 on the base support frame 1 is provided on the base support 1, and a transmission assembly 6 for synchronously driving the rear support frame 2 to flip when the front support frame 3 flips is provided between the front support frame 3 and the rear support frame 2. A transmission assembly 6 is provided between the front support frame 3 and the rear support frame 2, and the flip angles of the front support frame 3 and the rear support frame 2 can be adjusted synchronously through the transmission assembly 6. When the front support frame 3 flips along the pitch angle, the rear support frame 2 can be synchronously driven to flip synchronously. On the one hand, it is convenient to adjust the tilt angles of the front support roller 31 and the rear support roller 21. At the same time, the axes on the front support roller 31 and the rear support roller 21 can always remain parallel.

A mounting sleeve is also fixedly mounted on the front bracket, and the worm 52 is rotatably arranged inside the mounting sleeve. And the worm 52 cannot move inside the mounting sleeve along the axis direction of the mounting sleeve. By rotating the worm 52, the worm 52 can be flipped relative to the worm wheel 51, thereby driving the front support frame 3 to flip on the base bracket 1 to achieve the angle adjustment of the front support frame 3. The structure is simple and easy to operate, which is convenient for the angle adjustment of the front support frame 3.

[0053] In some embodiments, the transmission assembly 6 may be configured as follows: Figure 2 , Figure 3 See also Figure 2 , Figure 3The transmission assembly 6 includes a first fixed rod 61, a second fixed rod 62 and a support rod 63. The first fixed rod 61 is fixedly mounted on the front support frame 3 and is located below the front support frame 3. The axis of the first fixed rod 61 is spaced and parallel to the axis of the front support frame 3 on the base support 1; the second fixed rod 62 is fixedly mounted on the rear support frame 2 and is located below the rear support frame 2. The axis of the second fixed rod 62 is spaced and parallel to the axis of the rear support frame 2 on the base support 1; the two ends of the support rod 63 are respectively hinged on the first fixed rod 61 and the second fixed rod 62. The first fixed rod 61 and the second fixed rod 62 are respectively fixedly mounted below the front support frame 3 and the rear support frame 2. A plurality of support rods 63 are also connected to the first fixed rod 61 and the second fixed rod 62 brackets. The two ends of the plurality of support rods 63 are respectively hinged between the first fixed rod 61 and the second fixed rod 62. When the front support frame 3 swings on the base support 1 , it can drive the first fixing rod 61 to move, and drive the second fixing rod 62 to move through the support rod 63 , thereby driving the rear support frame 2 to swing synchronously on the base support 1 .

[0054] Preferably, in this embodiment, a support assembly for strengthening the support strength of the front support frame 3 and the rear support frame 2 is provided on both the front support frame 3 and the rear support frame 2. The support assembly includes a push rod hingedly provided on the front support frame 3 or the rear support frame 2, and a sliding sleeve slidably provided on the base support 1 along the first direction. The two ends of the push rod are respectively hingedly provided on the front support frame 3 and the sliding sleeve, and when the front support frame 3 or the rear support frame 2 is flipped, the sliding sleeve can be driven to slide on the base support 1. And a tightening bolt is threadedly connected on the sliding sleeve, and the sliding sleeve can be fixed to the base support 1, thereby achieving the function of supporting the front support frame 3 and the rear support frame 2. Ensure the stability of the installation of the rim 11 when it is placed between the front support frame 3 and the rear support frame 2.

[0055] In some embodiments, the front support frame 3 may be configured as follows: Figure 3 See the structure shown.

Two moving blocks 32 are slidably arranged on the support frame, and the two front support rollers 31 are rotatably arranged on the two moving blocks 32 respectively. By adjusting the relative positions of the two moving blocks 32, the spacing between the two front support rollers 31 can be changed. The outer diameters of the front and rear ends of the rim 11 are different, so the spacing between the two front support rollers 31 can be adjusted according to the outer diameter of the rim 11. Ensure stable support for the end of the rim 11, thereby ensuring the inclination angle of the rim 11. In this embodiment, the outer dimensions of the rims 11 of different specifications can be supported by adjusting the spacing between the two front support rollers 31. The structure is simple and can effectively improve the stability of the rim 11 during support.

When a single moving block 32 moves, the connecting arm 73 is driven to swing through the arc-shaped arm 72, thereby driving the other moving block 32 to move relatively. When the pushing assembly 74 drives a single moving block 32 to move, it can also drive the two moving blocks 32 to move together. This facilitates the adjustment of the relative positions of the two moving blocks 32. At the same time, the two moving blocks 32 move relatively synchronously, which can ensure that the center position between the two front support rollers 31 does not change, thereby ensuring the stability of the placement position of the rim 11.
