[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides a technical solution: a pump body surface inspection and fixing device, comprising a fixing seat 1, the top of the fixing seat 1 is welded with a support seat 3, the top of the support seat 3 is movably installed with a mounting seat 10, a threaded seat 11 is fixed on the mounting seat 10, a threaded column 12 is rotatably installed inside the threaded seat 11, one end of the threaded column 12 is installed with an extrusion seat 13, and a buffer plate 14 is fixed to the bottom of the extrusion seat 13, and the extrusion seat 13 is installed on the threaded column 12 through a bearing seat. A connecting component 9 is fixed to the bottom of the mounting seat 10, and a limiting seat 7 is fixed on the connecting component 9, and a supporting component 8 is installed on the limiting seat 7. The extrusion seat 13 pushes the buffer plate 14 to achieve wrapping and extrusion of the pump body. After the extrusion seat 13 moves downward, the distance between the pump body and the buffer plate 14 is adjusted when the pump body moves upward. When the pump body moves a short distance, the extrusion seat 13 realizes the support at the top position of the pump body.

[0029] The cam 24 is connected to the support 21 and the support 22 is connected to the support 21, and the cam 24 is connected to the support 21.

[0030] In this embodiment, the slot 5 is provided with an opening 15, the positioning tube 37 is movably mounted inside the opening 15, and a lifting mechanism 34 is fixed to the bottom of the fixed seat 1. The lifting mechanism 34 is a linear reciprocating electric push rod. One end of the electric push rod enters the interior of the opening 15 and contacts the positioning tube 37. The lifting mechanism 34 realizes the limited support of the movable seat 4 while pushing the movable frame 6 up and down. One end of the lifting mechanism 34 is movably mounted inside the positioning tube 37. A slider 36 is welded to the bottom of the movable seat 4. A slide groove 35 is opened on it, and the slider 36 is movably installed inside the slide groove 35. The bottom of the fixed seat 1 is welded with a support frame 2. A fixing groove 16 is opened on the inner wall of the support seat 3. An inclined plate 17 is fixed inside the fixing groove 16. The inclined plate 17 cooperates with the support assembly 8. The support assembly 8 includes a mounting hole 25. A fixing hole 19 is opened inside the support seat 3. The inclined plate 17 contacts the threaded tube 30 through its inclined surface. The threaded tube 30 pushes the limit seat 7 to tilt inward through the inclined surface displacement to complete the clamping and fixing of both sides of the pump body.

[0031] The cam 26 is fixed to the inner wall of the mounting hole 25 and a ring seat 27 is fixed on the rotating seat 26. The inner wall of the mounting hole 25 is provided with an annular groove 28. The ring seat 27 is rotatably mounted on the inner wall of the annular groove 28. A threaded rod 29 is fixed on one side of the rotating seat 26. A threaded tube 30 is rotatably mounted on the threaded rod 29. One end of the threaded tube 30 is movably contacted with the inclined plate 17. A connecting hole is provided at one end of the mounting hole 25. A limiting groove is provided on the inner wall of the connecting hole. A limiting block 31 is movably mounted in the limiting groove. One end of the limiting block 31 is fixed on the threaded tube 30. The supporting mechanism 20 is a tension spring. The tension spring provides a downward tension for the mounting seat 10. The mounting seat 10 completes the extrusion and fixation of the top of the pump body by moving downward to enable the extrusion seat 13 to complete the extrusion and fixation of the pump body.

[0032] When the device is in use, the telescopic column of the lifting mechanism 34 is fully extended to the inside of the lifting mechanism 34 through an external switch. After the telescopic column is taken out from the inside of the opening 15, the movable seat 4 is limited. The movable seat 4 slides in the inside of the slide groove 35 through the slider 36. As the movable seat 4 is pulled out, sufficient operating space is provided for the early installation of the pump body. After the pump body is installed on the movable frame 6 through the lifting equipment, one end of the limiting seat 7 supports one end of the movable seat 4. When the pump body is installed, the movable seat 4 slides horizontally and returns to the top of the fixed seat 1. After the movable seat 4 returns to its position, the extrusion seat 13 is pushed downward by rotating the threaded column 12. After the extrusion seat 13 moves downward, it adjusts the contact height with the starting top of the pump body, and the lifting mechanism 34 is started to enter the inside of the opening 15 to limit and fix the movable seat 4. As the telescopic column of the lifting mechanism 34 moves, one end of the telescopic column enters the inside of the positioning tube 37, and the telescopic column continues to rise to push the movable frame 6 to move upward. When the pump body is lifted up, the pump body contacts the buffer plate 14. The pump body continues to rise, and the buffer plate 14 and the extrusion seat 13 cooperate to push the mounting seat 10 upward. The mounting seat 10 drives the limit seat 7 to move upward through the connecting seat 21. When the limit seat 7 moves upward, one end of the threaded tube 30 contacts the inclined plate 17. As the rising height is different, the threaded tube 30 pushes the limit seat 7 to tilt inward. The limit seat 7 is tilted inward by the fixing tube 24 to clamp the two ends of the pump body. When the limit seat 7 cannot move upward, the clamping of the pump body side is completed. The extrusion seat 13 and the movable frame 6 realize the clamping and fixing of the upper and lower ends, and the multi-point fixation of the pump body is avoided. The influence of rotation and shaking during maintenance is avoided. When the diameter of the pump body is different, the rotating seat 26 is rotated by the tool, and the rotating seat 26 drives the threaded rod 29 to rotate and push the threaded tube 30 to move. After the threaded tube 30 is displaced, it pushes the limit seat 7 to tilt, and the starting tilt angle of the limit seat 7 is adjusted, thereby facilitating the clamping and fixing of the pump body in the later stage.
