Description

Technical Field

[0001] The utility model relates to the technical field of pump body castings, in particular to a clamp for pump body castings. Background Art

[0002] The pump casing of a water pump is generally cast. Since cast iron has a certain shock-absorbing effect, low hardness, and a certain oil absorption effect, it can reduce damage to the shaft and has a good sealing effect, making it an ideal material for making pump casings. The precision of the blank after casting is generally low, and it needs to go through processes such as polishing, milling the end face, drilling, rough boring, and fine boring. The blank size prepared by the same core is basically the same. Due to the low casting precision of the workpiece, for special castings such as pump casings.

[0003] Traditional clamps are used to clamp pump castings for polishing and other operations, and they need to be loosened and tightened multiple times to change the angle. Not only is it difficult to adjust the angle, but the operation is also complicated and inconvenient to use.

[0004] The Chinese utility model patent with application number CN202220615048.3 proposes a pump casting fixture, which adjusts the height of the workpiece by setting two support nuts. The two V-shaped supports can make the center of the workpiece on the center line of the two first adjustment plates. The first adjustment nut is used to adjust the position of the adjustment plate, and then the pressure head at the end is used to clamp and fix the workpiece. After the end faces on both sides of the workpiece are milled, the workpiece is turned over, and the workpiece is clamped again by the second fixture, and the bottom surface of the workpiece is milled;

[0005] Although this pump casting clamp can be clamped, it requires the cooperation of multiple clamps to complete clamping, fixing and adjustment, and the operation is relatively complicated and the adaptability is poor.

[0006] Therefore, a clamp for a pump body casting is proposed. Utility Model Content

[0027] like Figures 1 to 4 As shown, a specific embodiment of the utility model provides a clamp for a pump body casting, the clamp includes a cylindrical bracket 3 for supporting the casting 4, the cylindrical bracket 3 is rotatably connected to the vertical plate 2, the vertical plate 2 is fixedly mounted on the base 1, the clamp includes a clamping and fixing mechanism, the clamping and fixing mechanism also includes a second rotating wheel 8 fixedly connected to the left end of the cylindrical bracket 3, a servo motor 9 is fixedly mounted on one side of the second rotating wheel 8, the output shaft of the servo motor 9 passes through the second rotating wheel 8 and is fixedly connected to one end of a screw rod 10, the other end of the screw rod 10 is rotatably connected to the inner wall of the cylindrical bracket 3, the outer side of the screw rod 10 is threadedly connected to a movable block 11, the right end of the cylindrical bracket 3 is fixedly connected to a fixed block 12, the outer sides of the movable block 11 and the fixed block 12 are both provided with a first connecting block 15, the first connecting block 15 is hinged to one end of a connecting rod 16, the other end of the connecting rod 16 is hinged to a second connecting block 17, and the second connecting block 17 is fixedly mounted on a clamping plate 18.

[0028] Specifically, Figure 2 and Figure 3 As shown, the cylindrical bracket 3 is set in a cylindrical shape, and a movable block 11 is slidably connected to the outer side of the cylindrical bracket 3. An opening 13 is opened on the movable block 11, and the opening 13 is adapted to the cylindrical bracket 3. A slide rail 14 is opened on the outer side of the cylindrical bracket 3, and the slide rail 14 is adapted to the movable block 11. At least two groups of first connecting blocks 15 are set on the outer side of the movable block 11 and the fixed block 12. The first connecting blocks 15 are evenly arranged on the outer side of the movable block 11 and the fixed block 12. The clamping plate 18 is set in an arc shape, and two symmetrical groups of second connecting blocks 17 are arranged on the inner side of the clamping plate 18. When in use, the servo motor 9 drives the screw rod 10 to rotate, because the screw rod 10 thread transmission The movable block 11 is dynamically connected, and the movable block 11 is restricted on the cylindrical bracket 3 by the opening 13 and the slide rail 14, so the movable block 11 slides on the outside of the cylindrical bracket 3, and then because the movable block 11 and the first connecting block 15 on the outside of the fixed block 12 are hinged with a connecting rod 16, and the two groups of connecting rods 16 are hinged with the second connecting block 17 on the inside of the splint 18, the movable block 11 drives several groups of splints 18 to expand outward, and finally several groups of splints 18 are mortgaged on the outside of the casting 4, which is conducive to using the servo motor 9 to drive the splint 18 to quickly fix the castings 4 with different inner diameters, and avoid the casting 4 slipping during subsequent polishing and other work.

[0029] Specifically, Figure 2 and Figure 4As shown, the clamp includes an angle adjustment mechanism, which also includes a brake motor 5 arranged at the upper end of the base 1. The output shaft of the brake motor 5 passes through the vertical plate 2 and is fixedly connected to the first rotating wheel 6. The first rotating wheel 6 is connected to the second rotating wheel 8 through a belt 7. The first rotating wheel 6 and the second rotating wheel 8 are both arranged in a circular shape. The diameters of the first rotating wheel 6 and the second rotating wheel 8 are equal. The brake motor 5 drives the first rotating wheel 6 to rotate. Because the first rotating wheel 6 is connected to the second rotating wheel 8 through a belt 7, and the second rotating wheel 8 is fixedly connected to the cylindrical bracket 3, the first rotating wheel 6 drives the cylindrical bracket 3 to rotate. Then, because the casting 4 is fixed to the outer side of the cylindrical bracket 3 by the clamping and fixing mechanism, the first rotating wheel 6 can stop quickly and stably, so the first rotating wheel 6 can drive the casting 4 to rotate stably to a suitable position, which is conducive to using the brake motor 5 to drive the fixed casting 4 to rotate, and it is convenient to polish the various angles of the outer side of the casting 4.

[0030] Working principle: When in use, the servo motor 9 drives the screw rod 10 to rotate. Because the screw rod 10 is threadedly connected with the movable block 11, and the movable block 11 is restricted on the cylindrical bracket 3 through the opening 13 and the slide rail 14, the movable block 11 slides on the outside of the cylindrical bracket 3. Then, because the movable block 11 and the first connecting block 15 on the outside of the fixed block 12 are both hinged with the connecting rod 16, and the two groups of connecting rods 16 are hinged with the second connecting block 17 on the inside of the splint 18, the movable block 11 drives several groups of splints 18 to expand outward. Finally, several groups of splints 18 are mortgaged on the outside of the casting 4, which is conducive to using the servo motor 9 to drive the splint 18 to quickly fix the castings 4 with different inner diameters, so as to avoid the casting 4 from slipping during subsequent polishing and other work;

[0031] The brake motor 5 drives the first rotating wheel 6 to rotate. Since the first rotating wheel 6 is connected to the second rotating wheel 8 through the belt 7, and the second rotating wheel 8 is fixedly connected to the cylindrical bracket 3, the first rotating wheel 6 drives the cylindrical bracket 3 to rotate. Then, since the casting 4 is fixed to the outer side of the cylindrical bracket 3 by the clamping fixing mechanism, the first rotating wheel 6 can stop quickly and stably. Therefore, the first rotating wheel 6 can drive the casting 4 to rotate stably to a suitable position, which is conducive to using the brake motor 5 to drive the fixed casting 4 to rotate, and is convenient for polishing various angles of the outer side of the casting 4.
