Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fixing device for pump part processing, including a support platform 1. The bottom of the support platform 1 is rotatably connected to a rotating shaft 2 through a bearing. The end of the rotating shaft 2 is fixedly connected to a displacement mechanism 3. The end of the displacement mechanism 3 is fixedly connected to a clamping mechanism 4. The clamping mechanism 4 slides above the support platform 1. Among them, the displacement mechanism 3 includes a rotating disk 31 fixed to the end of the rotating shaft 2. An arc-shaped groove 32 is formed on the surface of the rotating disk 31. A sliding rod 33 is slidably connected inside the arc-shaped groove 32. The end of the sliding rod 33 is fixedly connected to a moving rod 34. The top of the moving rod 34 is fixedly connected to a fixed rod 35. The end of the fixed rod 35 penetrates through the support platform 1 and is fixedly connected below the clamping mechanism 4. The pump body is placed through the support platform 1, and then driven synchronously by the rotation of the rotating shaft 2, so that the displacement mechanism 3 can be driven, so that the clamping mechanism 4 can be adjusted, so that the pump body can be quickly positioned and clamped during processing, and the clamping can be adjusted according to the shape of the pump body.

[0023] According to Figure 2 and Figure 3 it can be known that it includes an L-shaped support plate 41 fixed to the top of the fixed rod 35. An adjusting bolt 42 is threadedly connected inside the L-shaped support plate 41. The end of the adjusting bolt 42 is rotatably connected to a clamping block 43 through a bearing. The fixed rod 35 can drive the L-shaped support plate 41 for large auxiliary displacement, so that it can be better located on the surface of the pump body for clamping. Then, by rotating the adjusting bolt 42 on the surface of the L-shaped support plate 41, the clamping block 43 can be finely adjusted, so as to better clamp on the surface of the pump body.

[0024] According to Figure 3 it can be known that a buffer pad 44 is fixedly connected to the surface of the clamping block 43. A V-shaped groove is formed on the surface of the buffer pad 44. Through the setting of the buffer pad 44, it can play a protective role when clamping the pump part, and through the setting of the V-shaped groove, it can better clamp and fix according to different shapes of the pump part.

[0025] According to Figure 3It can be seen that a connecting spring 45 is fixedly connected to the surface of the L-shaped support plate 41, and the end of the connecting spring 45 is fixedly connected to the clamping block 43. With the arrangement of the connecting spring 45, it can play a guiding and limiting role when the clamping block 43 is displaced.

[0026] According to Figure 3 It can be seen that a guiding groove 36 is formed at the top of the support platform 1, and the fixed rod 35 slides inside the guiding groove 36. By forming the guiding groove 36, it can play a guiding and limiting role in the displacement of the fixed rod 35.

[0027] According to Figure 4 It can be seen that a cylinder 5 is fixedly connected to the bottom of the support platform 1, the output end of the cylinder 5 is fixedly connected to an L-shaped rack 6, the surface of the L-shaped rack 6 is meshed with a gear 7, and the gear 7 is fixed on the surface of the rotating shaft 2. Driven by the cylinder 5, the L-shaped rack 6 can be displaced. When the L-shaped rack 6 is displaced, the gear 7 can be rotated, and when the gear 7 rotates, the rotating shaft 2 can be rotated.

[0028] The working principle of the present utility model: When in use, first place the pump body directly above the support platform 1, and then rotate the rotating shaft 2 at the bottom of the support platform 1. When the rotating shaft 2 rotates, it can synchronously drive the displacement mechanism 3 to rotate. By rotating the displacement mechanism 3, the clamping mechanism 4 can be displaced, so that the clamping mechanism 4 can clamp and fix the pump body on the support platform 1. When the rotating disk 31 included in the displacement mechanism 3 rotates, the arc-shaped groove 32 on the surface of the rotating disk 31 can be rotated, so that the sliding rod 33 can slide inside the arc-shaped groove 32. By sliding the sliding rod 33, the moving rod 34 is driven to displace. By displacing the moving rod 34, the fixed rod 35 can drive the clamping mechanism 4 to displace, so that multiple groups of clamping mechanisms 4 can be displaced synchronously. When multiple groups of clamping mechanisms 4 are displaced, the surface of the pump part can be clamped and fixed.
