[0017] The present utility model will be further described below in combination with the embodiments shown in the drawings.

[0018] A processing tool for the side hole of a speed limiter wheel, as Figures 1-5 shown, includes a vertical plate 1. Four fixing bases 2 are detachably installed on the vertical plate 1 at equal intervals. There is a bearing column 3 in the center of the fixing base 2, and the bearing column 3 is used to support the speed limiter rope pulley to be processed. A fixing member 4 is arranged inside the bearing column 3, and the fixing member 4 is used to limit the axial displacement of the speed limiter rope pulley to be processed. Two limit columns 5 are slidably connected to each of the left and right sides of the fixing base 2, and the limit columns 5 are slidably connected to the vertical plate 1, and the limit columns 5 are used to limit the radial displacement of the speed limiter rope pulley to be processed.

[0019] The fixing member 4 includes a screw rod 401 and a limit ring 402. The screw rod 401 is threadedly connected to the center of the bearing column 3, and one end of the screw rod 401 is slidably connected to the limit ring 402.

[0020] It further includes a positioning column 6. Pairs of positioning columns 6 are slidably connected to the vertical plate 1 in a centrosymmetric manner, and positioning holes 201 corresponding to the positions of each pair of positioning columns 6 are opened on the fixing base 2.

[0021] It further includes a bottom plate 7. The bottom plate 7 is detachably connected to the left and right sides of the bottom of the vertical plate 1. The bottom of the vertical plate 1 is stably placed on the use plane through the bottom plate 7, improving the stability of the whole tooling.

[0022] It further includes a reinforcing rib plate 8. A reinforcing rib plate 8 is arranged between the top of the bottom plate 7 and the rear side of the vertical plate 1. The design of the reinforcing rib plate 8 can enhance the connection strength between the bottom plate 7 and the vertical plate 1, ensuring the stability and durability of the tooling structure during the processing.

[0023] Working principle: First, place the speed limiter rope wheel to be processed on the bearing column 3 of the fixed seat 2. When installing the fixed seat 2, first align the positioning hole 201 on the fixed seat 2 with the positioning column 6 on the vertical plate 1, then move the fixed seat 2 closer to the vertical plate 1, and the positioning column 6 will naturally insert into the positioning hole 201 of the fixed seat 2, enabling the fixed seat 2 to be quickly and accurately installed in the preset orientation. Subsequently, tighten the screw 401 so that its end pushes the limit ring 402 to move towards the rope wheel until the limit ring 402 is in close contact with the end face of the rope wheel, thereby effectively preventing the axial movement of the rope wheel during processing. At the same time, slide the two limit posts 5 on each side to closely adhere to the spokes of the rope wheel to limit the radial movement of the rope wheel during processing and ensure the processing accuracy. After ensuring that the rope wheel is stably fixed, start the processing equipment (such as a drill press, milling machine, etc.) and process the side holes of the rope wheel according to the processing requirements. During the processing, since the rope wheel is effectively limited, a high processing accuracy and stability can be maintained. After the processing is completed, remove the limit posts 5, then loosen the screw 401, and take out the processed rope wheel from the tooling for the next round of processing.

[0024] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
