Description

Technical Field

[0001] This utility model relates to the field of pump impeller processing technology, specifically a pump impeller thermal spraying tooling. Background Technology

[0002] The pump impeller is the core component of the pump. Its main function is to convert the mechanical energy of the prime mover into the static and dynamic pressure energy of the working fluid, driving the fluid flow. Before use, the pump impeller is often thermally sprayed to improve its performance and service life. During thermal spraying, clamps are used to hold it, and currently, most use a three-jaw chuck. However, when using a three-jaw chuck, external tools are needed to turn the internal drive structure. This not only wastes time when fixing the pump impeller, but also increases the workload of the workers. Utility Model Content

[0003] The purpose of this invention is to provide a pump impeller thermal spraying fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pump impeller thermal spraying fixture, comprising a worktable and a motor fixed therein, and further comprising:

[0005] A rotating rod is fixedly connected to the output shaft of a motor. The other end of the rotating rod extends to the top of the worktable and is fixedly connected to a turntable. Several sliding rods are slidably connected inside the turntable. A chuck is fixedly connected to the surface of the sliding rods. The chuck is slidably connected to the inner wall of the turntable.

[0006] A spring is fitted onto the surface of the slide rod, with its two ends fixedly connected to one side of the chuck and the inner wall of the turntable, respectively. A limit structure is provided on one side of the slide rod, a locking plate is fixedly connected to one end of the slide rod, and a movable rod is hinged to the other end of the slide rod.

[0007] A movable disk is hinged to the other end of the movable rod. A movable ring is rotatably connected to the bottom of the disk surface. A connecting plate is fixedly connected to the top of the movable ring. A handle is fixedly connected to one side of the connecting plate. A fixing structure is provided on the top of the movable ring.

[0008] Preferably, the limiting structure includes a plurality of teeth fixedly connected to one side of the slide bar surface, a plurality of fixing plates fixedly connected to the top of the moving ring, a limiting plate fixedly connected to one side of the fixing plate, and the limiting plate and the teeth are used in conjunction.

[0009] Preferably, the fixing structure includes a fixing block fixedly connected to one side of the turntable surface, the top of the fixing block having a circular groove, the top of the moving ring being fixedly connected to a folded plate, the top of the folded plate having a fixing pin slidingly through it, and the other end of the fixing pin engaging with the interior of the circular groove.

[0010] Preferably, the card plate is arc-shaped, and the length of the card plate is greater than the distance between the moving disk and the turntable.

[0011] Preferably, the slide bars are distributed in a ring at equal intervals.

[0012] Preferably, a square groove is formed on one side of the slide bar surface, and the teeth are fixedly connected to the inner wall of the square groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the operator places the pump impeller on the movable plate and presses it down, the sliding rod moves the clamping plate, thus fitting and fixing the clamping plate to the inner wall of the pump impeller. As the operator pushes the handle, the movable ring moves. The limiting structure fixes the sliding rod after it has moved, and the fixing structure fixes the movable ring after it has rotated. This makes it easier for the operator to fix the pump impeller and reduces the workload of the operator. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a pump impeller thermal spraying fixture includes a workbench 1 and a motor 2 fixed inside it. The output shaft of the motor 2 is fixedly connected to a rotating rod 3. The other end of the rotating rod 3 extends to the top of the workbench 1 and is fixedly connected to a turntable 4. Several sliding rods 5 are slidably connected inside the turntable 4. A chuck 15 is fixedly connected to the surface of the sliding rod 5 and is slidably connected to the inner wall of the turntable 4. A spring 6 is sleeved on the surface of the sliding rod 5. The two ends of the spring 6 are fixedly connected to one side of the chuck 15 and the inner wall of the turntable 4, respectively. A limiting structure 11 is provided on one side of the sliding rod 5. The limiting structure 11 includes several teeth 111 fixedly connected to one side of the surface of the sliding rod 5. Several fixing plates 1 are fixedly connected to the top of the moving ring 10. 12. A limiting plate 113 is fixedly connected to one side of the fixed plate 112. The limiting plate 113 is used in conjunction with the inside of the teeth 111. When the operator places the pump impeller on the moving plate 9 and presses it down, it can drive the movable rod 7 to deflect. At the same time, it will push the slide rod 5, the chuck 15 and the clamping plate 8 to move and squeeze the spring 6. When the clamping plate 8 is in contact with the inner wall of the pump impeller, the operator needs to push the handle 13 to make the moving ring 10 rotate and drive the fixed plate 112 and the limiting plate 113 to move. Then the limiting plate 113 is placed inside the teeth 111, so as to limit and fix the slide rod 5 after it has moved. One end of the slide rod 5 is fixedly connected to the clamping plate 8.

[0023] The clamping plate 8 is arc-shaped, and its length is greater than the distance between the movable disk 9 and the turntable 4. When the clamping plate 8 moves and fits against the inner wall of the pump impeller, its arc shape helps to better fix the pump impeller. The other end of the sliding rod 5 is hinged to a movable rod 7, and the other end of the movable rod 7 is hinged to the movable disk 9. The sliding rods 5 are evenly spaced in a ring. This design provides more stable support for the pump impeller when the operator places it on the movable disk 9 and moves the sliding rods 5. The bottom of the surface of the turntable 4 is rotatably connected to a movable ring 10, and the top of the movable ring 10 is fixedly connected to a connecting plate 12. A handle 13 is fixedly connected to one side of the connecting plate 12. A fixing structure 14 is provided on the top of the movable ring 10. 4 includes a fixed block 141 fixedly connected to one side of the surface of the turntable 4. The top of the fixed block 141 is provided with a circular groove 143. The top of the moving ring 10 is fixedly connected with a folded plate 142. A fixing pin 144 slides through the top of the folded plate 142. The other end of the fixing pin 144 is used to cooperate with the inside of the circular groove 143. When the operator pushes the handle 13 and drives the moving ring 10 to rotate, the operator can pass the fixing pin 144 through the top of the folded plate 142 and insert it into the circular groove 143, thereby limiting the rotation of the moving ring 10. A square groove is provided on one side of the surface of the slide rod 5. The teeth 111 are fixedly connected to the inner wall of the square groove. When the slide rod 5 moves, this design will not cause the teeth 111 to jam with the spring 6.

[0024] Working principle: Before applying thermal spray to the pump impeller, the operator first places the pump impeller on the moving plate 9 and presses it down. As the moving plate 9 moves downward, it causes the movable rod 7 to deflect, simultaneously pushing the slide rod 5, chuck 15, and clamping plate 8 outward. At this time, the spring 6 is compressed. When the clamping plate 8 is in contact with the inner wall of the pump impeller, the operator pushes the handle 13, causing the moving ring 10 to rotate, which in turn moves the fixed plate 112 and the limiting plate 113. Then, the limiting plate 113 is positioned inside the teeth 111, thereby limiting and fixing the moved slide rod 5. Next, the worker needs to insert the fixing pin 144 through the top of the folded plate 142 and into the circular groove 143 to fix the rotating moving ring 10. After fixing, the worker then starts the motor 2 and the thermal spraying equipment to process it. After processing, the worker can pull out the fixing pin 144 to release the limit on the moving plate 9, and then push the handle 13 and rotate the moving plate 9 so that the limit plate 113 disengages from the teeth 111. Then, when the worker removes the processed pump impeller, the spring 6 can push the slide bar 5, the clamping plate 8 and the moving plate 9 back to the starting position through its own elastic force.
