Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a water pump shaft processing and grinding device. Background Art

[0002] When processing the water pump shaft, after the pump shaft is cut, it is necessary to quench the cut pump shaft to increase the hardness of the pump shaft, and then use an external cylindrical grinder to grind the pump shaft to the required size. Due to the high precision of the grinder, the use of an external cylindrical grinder to grind the pump shaft can ensure the accuracy of the pump shaft after processing.

[0003] When using a cylindrical grinder for processing, it is necessary to machine a center hole at both ends of the pump shaft, and then use a thimble to support both ends of the pump shaft before the pump shaft can be processed. The center hole is the reference for processing the pump shaft. When processing large pump shafts, it is necessary to use a crane to lift the pump shaft to complete the up and down of the pump shaft. Due to the small size of the center hole, the stability cannot be guaranteed when the crane lifts the pump shaft, which makes it inconvenient to use the thimble to lift the center hole. If the thimble damages the center hole when clamping the pump shaft, causing the axis of the two center holes to deviate, the center hole can only be repaired before processing. In this way, the device directly uses a crane for lifting when clamping large pump shafts, which is very inconvenient and needs to be improved.

[0004] Therefore, we propose a water pump shaft processing and grinding device to solve the above problems. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, by arranging two supporting mechanisms, can ensure the stability of the pump shaft support when supporting the pump shaft. When clamping the pump shaft, it can be directly hoisted and clamped without using a crane. When clamping, the pump shaft can be hung on the wedge-shaped support block, and then the wedge-shaped support block is driven to move upward. The upwardly moved wedge-shaped support block can drive the pump shaft to move upward. After the center hole of the pump shaft moves to a position flush with the ejector pin, the ejector pin can be directly used to support the center hole of the pump shaft. In this way, when clamping, it is not directly hoisted, so that the pump shaft is stable when clamping, thereby avoiding the problem that the ejector pin may damage the center hole.

[0015] 2. The present invention sets a first gear, a rotating sleeve and a bevel gear for use in conjunction. When the connecting sleeve is rotated, the rotating connecting sleeve can drive the bevel gear to rotate. After the wedge-shaped support block presses the pump shaft, when the bevel gear continues to rotate, the bevel block compresses the first spring, so that the bevel block can move into the housing. As a result, when the bevel gear rotates, the bevel gear cannot drive the rotating sleeve to move through the bevel block, thereby ensuring that the force of the wedge-shaped support block to move up and drag the polished pump shaft is stable.

[0016] 3. The present invention can connect two supporting mechanisms by setting a sleeve, a rectangular rod and a fixed shaft for use. When the supporting mechanism is controlled to drive the pump shaft to move up or down, the sleeve can be rotated to directly control the two supporting mechanisms to drive the pump shaft to move up or down, thereby facilitating the use of the device.

[0026] Furthermore, a fourth bolt 35 is threadedly connected to the outer wall of the sleeve 21, and one end of the fourth bolt 35 passes through the sleeve 21 and abuts against the rectangular rod 22; by providing the fourth bolt 35, the sleeve 21 and the rectangular rod 22 can be fixed to ensure that the sleeve 21 will not move at will.

[0027] Furthermore, a vertical tube 36 is fixedly connected to the inner wall of the yield groove 4, and the inner wall of the vertical tube 36 is slidably connected to a limiting block 37, a side wall of the limiting block 37 is fixedly connected to a support column 38, and the outer wall of the support column 38 is sleeved with a second spring 39, and one end of the support column 38 is fixedly connected to the support plate 7; by setting the vertical tube 36, the limiting block 37 and the support column 38, etc., the support platform 3 and the support plate 7 can be connected in a limited manner to ensure the stability of the support plate 7 when moving up, and by setting the second spring 39, when resetting the support plate 7, the second spring 39 can push the support plate 7 to move downward.

[0029] In the present invention, when in use, the pump shaft is firstly hung on the wedge-shaped support block, and then the sleeve 21 can be rotated by the handle 33 and the pin shaft 32. The rotating sleeve 21 drives the rectangular rod 22 and the fixed shaft 23 to rotate, and the rotating fixed shaft 23 can drive the connecting sleeve 15, the rotating sleeve 12 and the first gear 11 to rotate, and the rotating first gear 11 drives the second gear 13 to rotate, and the rotating second gear 13 drives the screw rod 9 to rotate, and the rotating screw rod 9 can drive the first oblique block 5 to move, and the moving first oblique block 5 can drive the second oblique block 6 to move upward, and the upwardly moved second oblique block 6 can drive the support plate 7 and the wedge-shaped support block to move upward, and the upwardly moved wedge-shaped support block can drive the pump shaft to move upward, and after the center hole of the pump shaft moves to a position flush with the ejector pin, the ejector pin can be directly used to support the center hole of the pump shaft, so that when clamping, it is not directly hoisted, so that the pump shaft is stable when clamping, and thus the problem that the ejector pin may damage the center hole can be avoided; After the pump shaft is clamped, the sleeve 21 can be reversed to move the wedge-shaped support block downward, thereby separating the wedge-shaped support block from the pump shaft, and then the grinder body 1 can be used to grind the pump shaft. After the pump shaft is ground, the sleeve 21 can be further rotated to move the wedge-shaped support block upward to drag the ground pump shaft, and then the ejector pin can be removed to lift the pump shaft. When rotating the sleeve 21 so that the wedge-shaped support block moves up to hold the polished pump shaft, when the wedge-shaped support block is pressed against the pump shaft, when the sleeve 21 continues to be rotated, the rotating sleeve 21 drives the rectangular rod 22 and the fixed shaft 23 to rotate, and the rotating fixed shaft 23 can drive the connecting sleeve 15 to rotate, and the rotating connecting sleeve 15 can drive the bevel gear 14 to rotate. After the wedge-shaped support block is pressed against the pump shaft, when the bevel gear 14 continues to rotate, the bevel block 17 compresses the first spring 18, so that the bevel block 17 can move into the housing 16, and then when the bevel gear 14 rotates, the bevel gear 14 cannot drive the rotating sleeve 12 to move through the bevel block 17, so as to ensure that the force of the wedge-shaped support block to move up to hold the polished pump shaft is stable.
