[0014] A water pump impeller press-fitting method includes the following steps: S1. Before starting work, the water pump body is placed on a placement plate in a first installation groove at the rear of a working plate. Multiple impellers can be sequentially sleeved and placed on a first column. A stud is then screwed into a screw hole. A second column is then installed on the first column. Under the action of an extrusion spring, the top plate is pushed upward, and the top plate pushes the impeller upward. At the same time, a wedge block on the second column restricts the impeller, thereby restricting the impeller on the first column and the second column. S2. At the same time, the moving device is started, driving the vertical plate, top plate, mounting plate and hydraulic cylinder to move to the top of the impeller placement device, and the hydraulic cylinder drives the centering clamping chuck to move from top to bottom to clamp the top impeller, and then the hydraulic cylinder drives the centering clamping chuck to move upward, and the centering clamping chuck drives the impeller to move upward, squeezing the wedge block, the wedge block pushes the slider, the slider squeezes the first spring, and the wedge block enters the second slide groove, thereby removing the top impeller from the impeller placement device. When the top impeller is removed, the impeller on the lower side moves upward under the elastic force of the squeezing spring, and then stops on the outer surface of the second column under the restriction of the wedge block, which is convenient for the subsequent centering clamping chuck to clamp, and then the moving device drives the centering clamping chuck to return to the front position just above the working disk; S3, start the intermittent rotation device, the second motor drives the first rotating rod to rotate, the first rotating rod drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the second rotating rod to rotate, the second rotating rod drives the driving plate to rotate, the driving plate drives the driving rod to rotate, the driving rod enters the driving groove, and squeezes the driving groove while the driving rod rotates, thereby driving the driving disc to rotate clockwise, and then the driving rod slides out of the driving groove. At this time, the driving disc stops rotating, and the arc block is driven to rotate into the arc groove. The arc block and the inner wall of the arc groove are tightly attached, so that the arc block restricts the limiting block to prevent the driving disc from rotating, thereby driving the working disc to rotate, affecting the press-fitting of the impeller and the water pump body, and the driving rod slides in different driving grooves in turn, thereby driving the driving disc to rotate in turn, and stops rotating, so that the hydraulic cylinder on the working disc drives the impeller to be press-fitted onto the mounting shaft of the water pump, which is convenient for the staff to take out the press-fitted water pump and place the water pump body to be press-fitted; S4. During the rotation of the working disc, the semi-conical gear ring and the reciprocating clamping device cooperate with each other to clamp or release the water pump body. When the water pump body rotates from the left position to the front position, the reciprocating clamping device gradually clamps the water pump body. When the water pump body reaches the front position, the hydraulic cylinder drives the centering clamping chuck to move downward, driving the impeller and the water pump body to be press-fitted.

At the same time, the design of the wedge block and the first spring can automatically push the impeller to the position to be clamped, and quickly clamp it through the centering clamping chuck, realizing continuous supply of impellers and reducing manual operation time. The pressing method of the present invention has clear steps and the automated process reduces the difficulty of operation.

[0020] When in use, place the water pump body in the first mounting groove 21, the intermittent rotating device 3 drives the working disk 2 to rotate, and the working disk 2 drives the water pump body to rotate. At the same time, the moving device 5 drives the fixed plate 6 to move, and the vertical plate 8 drives the top plate 9, the hydraulic cylinder 10, the mounting plate 11 and the centering clamping chuck 12 to move to the top of the impeller placement device 7, and the smelting is clamped by the centering clamping chuck 12. Then the moving device 5 drives the centering clamping chuck 12 to return to its original position. During the rotation of the water pump body, the reciprocating clamping device 4 clamps and releases the water pump body. When the working disk 2 drives the water pump body to approach the bottom of the centering clamping chuck 12, the reciprocating clamping device 4 clamps the water pump body. When the water pump body reaches the bottom of the centering clamping chuck 12, the intermittent rotating device 3 drives the working disk 2 to stop rotating intermittently. At this time, the hydraulic cylinder 10 drives The centering clamping chuck 12 moves downward to press the impeller onto the mounting shaft of the water pump body. After the installation is completed, the hydraulic cylinder 10 drives the centering clamping chuck 12 away from the water pump body. At the same time, the moving device 5 drives the centering clamping chuck 12 to clamp the new impeller. At the same time, the intermittent rotating device 3 drives the working disk 2 to rotate.

After the impeller is clamped, the electric telescopic rod 53 drives the device to return to its original position. Through the cooperation of the moving device 5 and the vertical plate 8, the top plate 9, the mounting plate 11 and the hydraulic cylinder 10, the impeller can be automatically clamped and pressed through the centering clamping chuck 12, and the work efficiency is high.

[0023] A first ring groove 102 is defined in the middle of the inner wall of the cavity 101 . A semi-conical ring gear 16 is installed in the first ring groove 102 . The semi-conical ring gear 16 is fixedly mounted on the front side of the first ring groove 102 .

[0024] The reciprocating clamping device 4 includes a reciprocating screw 41, a fixed rod 42, a bevel gear 43, a second driving block 44, a first rack 45, a driving gear 46 and a second rack 47. The driving gear 46 is rotatably installed in the middle of the bottom wall of the first mounting groove 21. A first slide groove 23 is provided in the middle of the bottom wall of the first mounting groove 21. The reciprocating screw 41 is rotatably installed in the first slide groove 23. The outer surface of the reciprocating screw 41 is provided with a second driving block 44 that slides with the reciprocating screw 41. The first rack 45 and the second rack 47 are distributed on both sides of the driving gear 46, and the first rack 45 and the second rack 47 are meshed. The first rack 45 and the second rack 47 are both slidably connected to the bottom of the first mounting groove 21. The ends of the upper ends of the first rack 45 and the second rack 47 that are away from each other are fixedly installed with a fixed block 48. The upper end of the second driving block 44 passes through the first slide groove 23 and is fixedly connected to the bottom of a fixed block 48.

The two limiting rods 412 are jointly fixedly installed with a splint 410 at one end near the mounting block 49 on the other side, and a plurality of fourth springs 411 are jointly fixedly installed between the splint 410 and the mounting block 49. A fixing rod 42 is fixedly installed at one end of the reciprocating screw 41. The fixing rod 42 rotates and extends through the first ring groove 102 and is fixedly installed with a bevel gear 43. The bevel gear 43 is meshed with the semi-circular bevel gear ring 16. The limiting rod 412 is fixedly installed with a second baffle 413 at one end away from the splint 410. The inner wall of the first mounting groove 21 is fixedly installed with two third slide rods 414 distributed on both sides of the driving gear 46.

The fixed blocks 48 on both sides are slidably connected with the third slide rod 414.

[0025] When in use, in the initial state, the water pump to be pressurized is placed in the first mounting groove 21 in the rear position. When the intermittent rotating device 3 works, it drives the working disk 2 to rotate clockwise, driving the water pump to be pressurized in the rear position to rotate to the left position. At this time, the bevel gear 43 is engaged with the semi-circular bevel gear ring 16. When the working disk 2 drives the water pump body in the left position to move forward, the bevel gear 43 rotates continuously, driving the fixed rod 42 to rotate, the fixed rod 42 drives the reciprocating screw 41 to rotate, and the reciprocating screw 41 rotates and drives the second drive block 44 to slide in the first slide groove 23 gradually. Close to the driving gear 46, the second driving block 44 drives the fixed block 48 to move toward the middle. When the fixed block 48 moves, it drives the first rack 45 to move. The movement of the first rack 45 drives the driving gear 46 to rotate, thereby driving the second rack 47 to slide, thereby driving the fixed block 48 on the other side to move closer to the middle. The fixed blocks 48 on both sides drive the clamping plates 410 on both sides to move closer to the middle to clamp the water pump body, so that the water pump body is in the center position, avoiding the water pump body from moving during the press-fitting process, improving the press-fitting accuracy of the impeller, and when the water pump body reaches the centering clamping position When the chuck 12 is below, the working disk 2 stops rotating. At this time, the reciprocating screw 41 stops rotating. At this time, the second driving block 44 is closest to the driving gear 46. At this time, it is in a state of maximum clamping force. When the impeller is pressed, the intermittent rotating device 3 drives the water pump body to move from the front position to the right position. At this time, the reciprocating screw 41 continues to rotate. At this time, the second driving block 44 gradually moves away from the driving gear 46, thereby driving the clamping plates 410 on both sides away from each other, thereby completing the release of the water pump body. When the water pump body moves to the right position, the bevel gear 43 and the semi-conical gear The ring is separated, and the working disk 2 stops rotating at this time and is in the intermittent working range, which is convenient for the staff to take out the water pump body. Then the working disk 2 continues to rotate. At this time, the first mounting groove 21 on the left is vacant and rotates to the rear position. The staff places the new water pump body in the first mounting groove 21, and so on. Through the cooperation of the reciprocating clamping device 4 and the semi-conical gear ring, the water pump body is clamped and released, with a high degree of automation, meeting the needs of factory use, and the first spring 74 provided plays a buffering role, which is convenient for clamping water pump bodies of different sizes.

The placement plate 15 does not conflict with the reciprocating clamping device 4. When in use, the water pump body is placed on the placement plate 15.

[0028] The impeller placement device 7 includes a first column 71 and a second column 72. The first column 71 is fixedly mounted on the middle part of the upper end of the fixing plate 6.

The lower surface of the wedge block 76 is provided with an upwardly inclined slope.

[0029] Before starting work, multiple impellers can be placed on the first column 71 in sequence, and then screwed into the screw hole 711 through the stud 78, and then the second column 72 is installed on the first column 71. Under the action of the elastic force of the extrusion spring 73, the top plate 77 is pushed upward, and the top plate 77 pushes the impeller upward. The wedge block 76 in the second column 72 restricts the impeller, thereby restricting the impeller to the first column 71 and the second column 72. The hydraulic cylinder 10 drives the centering clamping chuck 12 to move from top to bottom to clamp the top impeller, and then the hydraulic cylinder 10 drives the centering clamping chuck 12 to move upward, and the centering clamping chuck 12 drives the impeller to move upward, squeezing the wedge block 76, the wedge block 76 pushes the slider 75, the slider 75 squeezes the first spring 74, and the wedge block 76 enters the second slide groove 722, thereby removing the top impeller from the impeller placement device 7. When the top impeller is removed, the impeller on the lower side moves upward under the elastic force of the squeezing spring 73, and then stops on the outer surface of the second column 72 under the restriction of the wedge block 76, so as to be clamped by the subsequent centering clamping chuck 12.

Before starting work, the water pump body is placed on the placement plate 15 in the first installation groove 21 at the rear of the working plate 2. Multiple impellers can be sequentially sleeved and placed on the first column 71. Then, the stud 78 is screwed into the screw hole 711. Then, the second column 72 is installed on the first column 71. Under the action of the elastic force of the extrusion spring 73, the top plate 77 is pushed upward. The top plate 77 pushes the impeller upward. At the same time, the wedge block 76 on the second column 72 restricts the impeller, thereby restricting the impeller to the first column 71 and the second column 72. The uppermost impeller is then removed from the impeller placement device 7 by the action of the centering clamping chuck 12 and the centering clamping chuck 12. S3. Start the intermittent rotation device 3. The second motor 31 drives the first rotating rod 37 to rotate. The first rotating rod 37 drives the first gear 34 to rotate. The first gear 34 drives the second gear 35 to rotate. The second gear 35 drives the second rotating rod 38 to rotate. The second rotating rod 38 drives the driving plate 39 to rotate. The driving plate 39 drives the driving rod 310 to rotate. The driving rod 310 enters the driving groove 332. While the driving rod 310 rotates, the driving groove 332 is squeezed, thereby driving the driving disk 33 to rotate 90° clockwise. Then the driving rod 310 slides out of the driving groove 332. At this time, the driving disk 33 stops. Rotate, at this time drive the arc block 311 to rotate into the arc groove 361, the arc block 311 and the inner wall of the arc groove 361 are in close contact, so that the arc block 311 limits the limiting block 36, preventing the driving disc 33 from rotating, thereby driving the working disc 2 to rotate, affecting the press-fitting of the impeller and the water pump body, and the driving rod 310 slides in different driving grooves 332 in turn, thereby driving the driving disc 33 to rotate 90 degrees in turn and stop rotating, making it convenient for the hydraulic cylinder 10 on the working disc 2 to drive the impeller to be press-fitted onto the installation shaft of the water pump, and making it convenient for the staff to take out the press-fitted water pump and place the water pump body to be press-fitted; S4. During the rotation of the working disc 2, the water pump body is clamped or released through the cooperation of the semi-conical gear ring 16 and the reciprocating clamping device 4. In the initial state, the water pump to be pressurized is placed in the first mounting groove 21 at the rear position. When the intermittent rotating device 3 works, it drives the working disc 2 to rotate clockwise, driving the water pump to be pressurized at the rear position to rotate to the left position. At this time, the bevel gear 43 is engaged with the semi-conical gear ring 16. When the working disc 2 drives the water pump body on the left to move forward, the bevel gear 43 rotates continuously, driving the fixed The fixed rod 42 rotates, the fixed rod 42 drives the reciprocating screw 41 to rotate, the reciprocating screw 41 rotates and drives the second driving block 44 to slide in the first sliding groove 23 and gradually approach the driving gear 46, the second driving block 44 drives the fixed block 48 to move toward the middle, and the fixed block 48 drives the first rack 45 to move when moving. The movement of the first rack 45 drives the driving gear 46 to rotate, thereby driving the second rack 47 to slide, thereby driving the fixed block 48 on the other side to move closer to the middle, and the fixed blocks 48 on both sides drive the splints 410 on both sides to move closer to the middle to close the water The pump body is clamped to keep the water pump body in the center position, avoiding the water pump body from moving during the press-fitting process and improving the press-fitting accuracy of the impeller. When the water pump body reaches the bottom of the centering clamping chuck 12, the working disk 2 stops rotating. At this time, the reciprocating screw 41 stops rotating. At this time, the second driving block 44 is closest to the driving gear 46, and is in a state of maximum clamping force. When the impeller press-fitting is completed, the intermittent rotating device 3 drives the water pump body to move from the front position to the right position. At this time, the reciprocating screw 41 continues to rotate, and the second driving block 44 gradually Away from the driving gear 46, thereby driving the splints 410 on both sides away from each other, thereby completing the release of the water pump body. When the water pump body moves to the right position, the bevel gear 43 separates from the semi-circular bevel gear ring. At this time, the working disk 2 stops rotating and is in the intermittent working range, which is convenient for the staff to take out the water pump body. Then the working disk 2 continues to rotate. At this time, the first mounting groove 21 on the left is vacant and rotates to the rear position. The staff places the new water pump body in the first mounting groove 21, and so on, thereby continuously press-fitting the water pump body.

Before starting work, place the water pump body on the placement plate (15) in the first installation groove (21) at the rear of the working plate (2), and multiple impellers can be placed on the first column (71) in sequence, then screw the stud (78) into the screw hole (711), and then install the second column (72) on the first column (71). Under the action of the elastic force of the extrusion spring (73), the top plate (77) is pushed upward, and the top plate (77) pushes the impeller upward. At the same time, the wedge block (76) on the second column (72) restricts the impeller, thereby restricting the impeller on the first column (71) and the second column (72); S2. Simultaneously, the moving device (5) is started, driving the vertical plate (8), the top plate (9), the mounting plate (11) and the hydraulic cylinder (10) to move to the top of the impeller placement device (7). The hydraulic cylinder (10) drives the centering clamping chuck (12) to move downward from the top to clamp the top impeller. Then, the hydraulic cylinder (10) drives the centering clamping chuck (12) to move upward. The centering clamping chuck (12) drives the impeller to move upward, squeezing the wedge block (76). The wedge block (76) pushes the slider (75).

The driving plate 39 drives the driving rod 310 to rotate. The driving rod 310 enters the driving groove 332. When the driving rod 310 rotates, the driving groove 332 is squeezed, thereby driving the driving disk 33 to rotate 90 degrees clockwise. Then the driving rod 310 slides out of the driving groove 332. At this time, the driving disk 33 stops. The arc block 311 is stopped from rotating. At this time, the arc block 311 is driven to rotate into the arc groove 361. The arc block 311 and the inner wall of the arc groove 361 are in close contact, so that the arc block 311 restricts the limiting block 36, preventing the driving disc 33 from rotating, thereby driving the working disc 2 to rotate, affecting the press-fitting of the impeller and the water pump body. The driving rod 310 slides in different driving grooves 332 in turn, thereby driving the driving disc 33 to rotate 90° in turn and stop rotating, making it convenient for the hydraulic cylinder 10 on the working disc 2 to drive the impeller to be press-fitted onto the installation shaft of the water pump, and making it convenient for the staff to take out the press-fitted water pump and place the water pump body to be press-fitted; S4.

When the water pump body rotates from the left position to the front position, the reciprocating clamping device (4) gradually clamps the water pump body. When the water pump body reaches the front position, the hydraulic cylinder (10) drives the centering clamping chuck to move downward, driving the impeller and the water pump body to be press-fitted. When the water pump body rotates from the front position to the right position, the reciprocating clamping device (4) gradually releases the water pump body. The staff takes out the press-fitted water pump, and then replaces the water pump body to be press-fitted when it rotates to the rear position, thereby continuously press-fitting the water pump body.
