[0002] During the manufacturing process, especially after casting, forging, or machining, impellers often have burrs or uneven edges remaining on their surface. These burrs not only affect the appearance quality of the impeller but can also impact its performance and service life. Impeller grinding devices play a crucial role in impeller processing.

[0003] A grinding device for impeller production is used to grind finished impellers, removing burrs from the impeller surface and smoothing uneven surfaces. Existing impeller grinding devices often fix the impeller from the bottom, which can easily lead to localized stress concentration, deformation, or uneven surface. The clamping force applied by the fixture at the moment of clamping the impeller may damage the impeller or the fixture. Therefore, a grinding device for impeller production is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a grinding device for impeller production, which solves the problems of existing impeller grinding devices that often fix the impeller from the bottom, which can easily lead to local stress concentration, deformation or uneven surface, and the clamping force applied by the clamp at the moment of clamping the impeller may damage the impeller or the clamp.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A grinding device for impeller production includes a mounting box. A first motor is fixedly connected inside the mounting box. A first gear is fixedly connected to one output end of the first motor. A second gear is geared above the first gear. Screws are fixedly connected to both sides of the second gear. The two screws are arranged in a mirror image. A slide is threaded to the outer side of each of the two screws. A first connecting rod is fixedly connected above each of the two slides.

[0007] Furthermore, the mounting box has first limiting grooves on both sides above it, the upper ends of the two first connecting rods pass through the two first limiting grooves respectively, a first connecting plate is fixedly connected above the two first connecting rods, an electric push rod is fixedly connected above the two first connecting plates, and a second connecting plate is fixedly connected to the upper output end of the two electric push rods.

[0008] Furthermore, each of the two second connecting plates has a fixing groove on one side, and a limiting shaft is movably sleeved in each of the two fixing grooves. A transmission rod is movably sleeved inside each of the two limiting shafts. A limiting fixing head is fixedly connected to one inner end of each of the two transmission rods. A third connecting plate is fixedly connected to the outer side of each of the two transmission rods. A spring is fixedly connected to the inner side of each of the two third connecting plates. Two limiting shafts are fixedly connected to the inner side of each of the two springs.

[0009] Furthermore, a second motor is fixedly connected to the outer side of the second connecting plate, and a fourth gear is fixedly connected to the outer output end of the second motor. A third gear is toothed on one side of the fourth gear, and a neighboring limiting shaft is fixedly sleeved inside the third gear.

[0010] Furthermore, a fixed bracket is fixedly connected to the top of the mounting box, an electric guide rail is fixedly connected to the inner side of the fixed bracket, an electric slider is movably installed inside the electric guide rail, a connecting bracket is fixedly connected to the bottom of the electric slider, a fourth motor is fixedly connected to one side of the connecting bracket, and a grinding roller is fixedly connected to the inner output end of the fourth motor.

[0011] Furthermore, a control panel is fixedly connected to the outside of the fixed bracket, and the control panel is electrically connected to a first motor, two electric push rods, a second motor, an electric guide rail, and a fourth motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the setting of the sliding table, can fix the impeller from both sides, so that the impeller receives a more uniform force distribution during the grinding process, which is convenient for fixing impellers of different sizes. When the first motor is started, the first motor drives the second gear to rotate through the first gear. The second gear drives the sliding table to move through the screw. The two screws have opposite helical directions, so the two screws can drive the two sliding tables to move closer or further apart. The sliding table drives the two limiting fixing heads to move closer through the first connecting rod, the first connecting plate, the second connecting plate, the electric push rod and the limiting shaft. The two limiting fixing heads fix the impeller from both ends. Through this setting, the impeller can be fixed from both sides, so that the impeller receives a more uniform force distribution during the grinding process, which is convenient for fixing impellers of different sizes.

[0014] 2. The spring in this utility model can absorb part of the impact force when the impeller is clamped, thus preventing damage to the impeller surface and protecting the impeller. When the limiting fixing head clamps the impeller, the impact force generated is transmitted to the spring through the limiting fixing head, the transmission rod and the third connecting plate. The spring buffers the impact force. In this way, the impeller can absorb part of the impact force when it is clamped, thus preventing damage to the impeller surface and protecting the impeller.

[0025] like Figures 1-4As shown, a grinding device for impeller production includes a mounting box 1. A first motor 2 is fixedly connected inside the mounting box 1.

The two screws 5 are arranged in a mirror image. A slide table 6 is threadedly connected to the outer side of each of the two screws 5. A first connecting rod 8 is fixedly connected to the top of each of the two slide tables 6. By adopting the above technical solution, the two screws 5 are arranged in a mirror image and rotate in different directions, so the two slide tables 6 can be driven to move closer or further apart.

[0026] like Figures 1-4 As shown, the upper sides of the mounting box 1 are provided with first limiting grooves 7. The upper ends of the two first connecting rods 8 pass through the two first limiting grooves 7 respectively. The upper ends of the two first connecting rods 8 are fixedly connected to the upper ends of the two first connecting rods 8. The upper ends of the two first connecting rods 9 are fixedly connected to the upper ends of the two first connecting rods 9. The upper output ends of the two electric push rods 10 are fixedly connected to the upper ends of the two electric push rods 10. By adopting the above technical solution, the first limiting grooves 7 can limit the first connecting rods 8 to move linearly along the direction of the first limiting grooves 7.

[0027] like Figures 1-5 As shown, each of the two second connecting plates 11 has a fixing groove on one side. Each of the two fixing grooves has a limiting shaft 12 movably sleeved inside. Each of the two limiting shafts 12 has a transmission rod 15 movably sleeved inside. Each of the two transmission rods 15 has a limiting fixing head 16 fixedly connected to one end of its inner side. Each of the two transmission rods 15 has a third connecting plate 14 fixedly connected to its outer side. Each of the two third connecting plates 14 has a spring 13 fixedly connected to its inner side. Each of the two springs 13 has a limiting shaft 12 fixedly connected to its inner side. By adopting the above technical solution, a limiting baffle is installed on the limiting shaft 12, which can limit the limiting shaft 12 to rotate only on the fixing groove and will not move back and forth.

[0028] A buffer pad is provided at the connection position between the spring 13 and the limiting shaft 12, which can further improve the buffering effect;

[0029] The outer side of the limiting and fixing head 16 is made of a wear-resistant material with a certain friction force, which can effectively clamp the two ends of the impeller.

[0030] like Figures 1-6 As shown, a second motor 19 is fixedly connected to the outer side of a second connecting plate 11. A fourth gear 18 is fixedly connected to the outer output end of the second motor 19. A third gear 17 is toothed on one side of the fourth gear 18. An adjacent limiting shaft 12 is fixedly sleeved inside the third gear 17. With this arrangement, the second motor 19 can drive the limiting shaft 12 to rotate through the fourth gear 18 and the third gear 17. The limiting shaft 12 can drive the limiting fixing head 16 to rotate through the transmission rod 15.

[0031] The transmission rod 15 is square, which facilitates the limit shaft 12 to drive the transmission rod 15 to rotate.

[0032] like Figures 1-7 As shown, a fixed bracket 26 is fixedly connected to the top of the mounting box 1. An electric guide rail 20 is fixedly connected to the inner side of the fixed bracket 26. An electric slider 21 is movably installed inside the electric guide rail 20. A connecting bracket 22 is fixedly connected to the bottom of the electric slider 21. A fourth motor 23 is fixedly connected to one side of the connecting bracket 22. A grinding roller 24 is fixedly connected to the inner output end of the fourth motor 23. With this arrangement, the electric guide rail 20 can drive the electric slider 21 to move linearly, and the fourth motor 23 can drive the grinding roller 24 to rotate for grinding.

[0033] like Figures 1-7 As shown, a control panel 25 is fixedly connected to the outside of the fixed bracket 26. The control panel 25 is electrically connected to the first motor 2, two electric push rods 10, the second motor 19, the electric guide rail 20, and the fourth motor 23. With this configuration, the control panel 25 can control the first motor 2, the two electric push rods 10, the second motor 19, the electric guide rail 20, and the fourth motor 23.

[0034] In use, place the mounting box 1 on a horizontal plane, connect the external power supply through the control panel 25, hold the impeller between the two limiting fixing heads 16, start the first motor 2, the first motor 2 drives the second gear 4 to rotate through the first gear 3, the second gear 4 drives the slide table 6 to move through the screw 5. The two screws 5 have opposite spiral directions, so the two screws 5 can drive the two slide tables 6 to move closer or further apart. The slide table 6 drives the two limiting fixing heads 16 to move closer together through the first connecting rod 8, the first connecting plate 9, the second connecting plate 11, the electric push rod 10 and the limiting shaft 12. The two limiting fixing heads 16 fix the impeller from both ends.

[0035] When the limiting fixing head 16 clamps the impeller, the resulting impact force is transmitted to the spring 13 through the limiting fixing head 16, the transmission rod 15 and the third connecting plate 14, and the spring 13 buffers the impact force.

[0036] Once the impeller is fixed, the electric push rod 10 is activated to push the second connecting plate 11 upward. The second connecting plate 11 drives the impeller upward to the grinding position through the limiting shaft 12 and the limiting fixing head 16. The electric guide rail 20 is activated, and the electric guide rail 20 drives the connecting bracket 22 to move through the electric slider 21. The fourth motor 23 drives the grinding roller 24 to grind the impeller.

[0037] This utility model provides a grinding device for impeller production, which solves the problems of existing impeller grinding devices that often fix the impeller from the bottom, which can easily lead to local stress concentration, deformation or uneven surface, and the clamping force applied by the clamp at the moment of clamping the impeller may damage the impeller or the clamp.
