Description

Technical Field

[0001] The utility model relates to the technical field of water pump processing, and particularly relates to a turnover clamping mechanism for processing a water pump pump shell. Background Technique

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid, and is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspension liquids, and liquid metals.

[0003] Among the various components of a water pump, the pump shell is essential. It needs to bear a certain pressure, so generally the pump shell is made of metal. When processing the pump shell, drilling operations need to be carried out at different places on its surface. However, due to the irregular shape of the pump shell and the fact that general clamping structures can only rotate in one direction, when drilling the pump shell, it is necessary to repeatedly adjust its position for re-clamping, which is rather inconvenient and has low efficiency.

[0004] Therefore, how to realize a clamping device with a multi-angle rotation structure is a technical problem urgently to be solved in the industry. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a turnover clamping mechanism for processing a water pump pump shell, aiming to realize a clamping device with a multi-angle rotation structure.

[0018] It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0019] Referring to Figures 1-3 , an embodiment of the present invention is proposed, a flipping and clamping mechanism for processing a water pump housing, including a base 1. A mounting seat 2 is vertically and fixedly connected to the rear part of the upper surface of the base 1. The top end of the mounting seat 2 is horizontally rotatably connected to a connecting block 3. The other end of the connecting block 3 is fixedly connected to a device cylinder 4 with an open outer end. The other end of the device cylinder 4 is rotatably connected to a connecting frame 6 that is coaxial with it and has an open other end. The other end of the connecting frame 6 is fixedly connected to a connecting disk 7. A plurality of sliding grooves 8 are formed through the outer surface of the connecting disk 7 along a plurality of radial directions thereof. A slider 10 is slidably connected to the inside of each of the plurality of sliding grooves 8. A clamping column 11 is fixedly connected to the outer end surface of each of the plurality of sliders 10. The middle part of the inner surface of the connecting disk 7 is fixedly connected to a servo motor 12. A threaded rod 13 is fixedly connected to the outer end of the output shaft of the servo motor 12. A threaded sleeve 14 is threadedly connected to the outer surface of the threaded rod 13. A plurality of connecting rods 15 corresponding to the plurality of sliders 10 respectively are hinged to the outer surface of the threaded sleeve 14. The other ends of the plurality of connecting rods 15 are respectively hinged to the inner surface of the corresponding slider 10.

[0020] The device fixes the pump housing through a plurality of clamping columns 11. During actual use, the pump housing is closely attached to the outer surface of the connecting disk 7. Then, the servo motor 12 is controlled to operate. When its output shaft rotates, it will drive the threaded rod 13 to rotate. During the rotation of the threaded rod 13, the threaded sleeve 14 on its surface will move along its length direction. During this process, the threaded sleeve 14 will drive one end of the connecting rod 15 to move towards the direction of the connecting disk 7, and the other end of the connecting rod 15 will move outwards, thereby driving the plurality of sliders 10 to separate from each other until the plurality of clamping columns 11 abut against the inner surface of the pump housing. The clamping of the pump housing can be completed under the action of friction.

[0021] Furthermore, guide rods 9 are respectively fixedly connected to the inside of the plurality of sliding grooves 8 along their length directions. Slide holes corresponding to and adapted to the plurality of guide rods 9 are respectively formed through the side surfaces of the plurality of sliders 10. The plurality of sliders 10 are respectively slidably connected to the outer surfaces of the plurality of guide rods 9 through the plurality of slide holes.

[0022] The plurality of guide rods 9 play a role in guiding and limiting the plurality of sliders 10, ensuring that the movement directions of the plurality of sliders 10 will not deviate.

[0023] Furthermore, the central axes of the threaded rod 13 and the connecting disk 7 are located on the same straight line.

[0024] A rotating motor 5 is fixedly connected to the inside of the device cylinder 4. The output shaft of the rotating motor 5 is fixedly connected to the surface of the connecting frame 6.

[0025] The output shaft of the rotating motor 5, the connecting frame 6, and the central axis of the device cylinder 4 are all located on the same straight line.

[0026] At the front end of the upper surface of the base 1, a first hydraulic rod 16 is hinged, and the other end of the first hydraulic rod 16 is hinged to the rear part of the lower surface of the device cylinder 4. In the middle of the upper surface of the base 1, a second hydraulic rod 17 is hinged, and the other end of the second hydraulic rod 17 is hinged to the front part of the lower surface of the first hydraulic rod 16.

[0027] The device is rotationally connected to the device cylinder 4 through the mounting seat 2. The device cylinder 4 can rotate on the mounting seat 2. At the same time, its outer end is also rotationally connected to a connecting frame 6 coaxial with it. A clamping structure is arranged outside the connecting frame 6. After clamping the pump shell through the clamping structure, first, it can control the pump shell to rotate horizontally under the drive of the rotating motor 5 inside the device cylinder 4, and it can also control the device cylinder 4 to rotate vertically under the drive of the first hydraulic rod 16 and the second hydraulic rod 17. When processing the pump shell, using this device for clamping does not require repeated adjustment of the position of the pump shell, improving the processing efficiency.

[0028] During operation, first, the pump shell is clamped through the clamping structure, and the pump shell is pressed against the outer surface of the connecting disk 7. Then, control the servo motor 12 to operate. When its output shaft rotates, it will drive the threaded rod 13 to rotate. During the rotation of the threaded rod 13, the threaded sleeve 14 on its surface will move along its length direction. During this process, the threaded sleeve 14 will drive one end of the connecting rod 15 to move towards the direction of the connecting disk 7, and the other end of the connecting rod 15 will move outwards, thereby driving multiple sliders 10 to separate from each other until multiple clamping columns 11 abut against the inner surface of the pump shell. Under the action of friction, the clamping of the pump shell can be completed. After clamping the pump shell through the clamping structure, first, it can control the pump shell to rotate horizontally under the drive of the rotating motor 5 inside the device cylinder 4, and it can also control the device cylinder 4 to rotate vertically under the drive of the first hydraulic rod 16 and the second hydraulic rod 17. When processing the pump shell, using this device for clamping does not require repeated adjustment of the position of the pump shell, improving the processing efficiency.
