Description

Technical Field

[0001] This invention relates to the field of impeller press fitting, and in particular to an integrated tooling for picking up and centering materials for a water pump motor. Background Technology

[0002] In the manufacturing process of water pumps, impeller press-fitting is a critical step, as its assembly quality directly affects the pump's operating efficiency and service life. Traditional impeller press-fitting processes typically rely on multiple dispersed tooling devices and extensive manual labor, resulting in a series of technical bottlenecks and operational drawbacks. Firstly, the alignment of the impeller and pump shaft depends primarily on manual adjustment based on operator experience, which is not only inefficient but also difficult to guarantee in alignment accuracy, easily leading to problems such as press-fitting misalignment, impeller damage, or increased pump vibration. Secondly, existing clamping devices often have a simple structure, lacking adaptability and compatibility with different pump specifications, and frequent tooling changes further reduce production efficiency. Furthermore, impeller loading is mostly done manually, piece by piece, resulting in inaccurate positioning, mismatched cycle times, and high labor intensity, making it difficult to meet the demands of automated continuous production. The press-fitting process is also mostly rigid downward pressing, lacking buffering and correction mechanisms, easily causing surface damage to the workpiece or uneven pressing force, affecting product consistency. In terms of support and centering, traditional tooling functions are separate. Pump body centering and impeller support are often performed in separate steps, resulting in low equipment integration, large space occupation, cumbersome operation procedures, and low overall assembly efficiency. Therefore, the industry urgently needs a high-precision tooling device that integrates material handling, centering, and pressing functions to improve the quality stability and production efficiency of impeller assembly. Summary of the Invention

[0003] The main objective of this invention is to provide an integrated tooling for picking up and centering water pump motors, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A water pump motor material handling and centering integrated tooling includes a base, with supporting side plates fixedly installed on both the left and right sides of the upper end of the base, and a top plate fixedly installed between the two supporting side plates. A placement tray is fixedly installed in the middle of the upper end of the base, with clamping devices on both sides of the placement tray. A pressing device is fixedly installed at the bottom of the top plate, with a supporting device installed at the bottom of the pressing device, and a centering device fixedly installed at the bottom of the supporting device. A feeding assembly is installed on one side of the pressing device.

[0005] Preferably, the clamping device includes a positive and negative lead screw and two sliding rods. The positive and negative lead screw is rotatably mounted between two support side plates, and the two sliding rods are fixedly mounted between the two support side plates, with the two sliding rods distributed on the front and rear sides of the positive and negative lead screw. Both sides of the outer surface of the positive and negative lead screw are threaded with driving blocks. The ends of the two driving blocks that are close to each other are fixedly mounted with figure-eight rods. Both ends of the figure-eight rods are rotatably mounted with hinge rods. The ends of the hinge rods away from the figure-eight rods are fixedly mounted with arc-shaped blocks. One end of the positive and negative lead screw rotatably passes through the support side plate and is fixedly mounted with a handle. The positive and negative lead screw and the sliding rods are both set through the placement plate. The positive and negative lead screw and the placement plate are rotatably connected, and the sliding rods are fixedly connected to the placement plate. By rotating the handle, the positive and negative lead screws are rotated, driving the two sets of figure-eight rods to move towards each other. The hinge rods drive the arc-shaped blocks to hug the pump body from both sides, achieving a flexible and adaptive clamping effect. This structure is compatible with pump bodies of different sizes, effectively preventing workpiece displacement or skew during the press-fitting process and ensuring that the shaft hole and shaft rod always maintain high-precision alignment.

A push plate is fixedly installed on the outer surface of the belt and slides within the movable groove. A third motor is fixedly installed at the bottom of the placement cylinder, and the output end of the third motor is fixedly connected to one of the rotating shafts. The operator only needs to stack the impellers in the placement cylinder. The third motor drives the rotating roller and the belt mechanism to rotate, causing the push plate to move horizontally along the movable groove, pushing the impellers sequentially through the rectangular connecting pipe into the working cylinder and accurately conveying them to the pressing station above the support device. This automated feeding process not only eliminates the positional deviation of manual placement but also achieves uninterrupted operation, providing a solid foundation for efficient production.

[0009] Preferably, a collar is fitted on the outer surface of the placement cylinder, and support rods are fixedly installed on both sides of the collar, with the end of the support rod away from the collar being fixedly connected to a support side plate.

[0013] Preferably, the bottom of the working cylinder is connected to the center of the first, second, and third discs, and when the second disc rotates forward and backward, it can drive multiple support blocks to open and close the center of the second disc.

The pressing device is equipped with a spring buffer structure and a rubber-ringed insert rod, ensuring a smooth pressing process and preventing the impeller from falling off during conveying and pressing. The feeding assembly uses a belt pusher plate structure to automatically push the impeller, supporting continuous feeding, reducing manual intervention, and improving production efficiency. The supporting device uses a motor to drive the opening and closing of the support block, providing stable support for the impeller before pressing and quickly allowing it to pass smoothly during pressing.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1 like Figure 1-8 As shown, a water pump motor material handling and centering integrated tooling includes a base 1. Support side plates 2 are fixedly installed on both the left and right sides of the upper end of the base 1. A top plate 3 is fixedly installed between the two support side plates 2. A placement tray 4 is fixedly installed in the middle of the upper end of the base 1. Clamping devices 5 are provided on both sides of the placement tray 4. A pressing device 9 is fixedly installed at the bottom of the top plate 3. A support device 8 is installed at the bottom of the pressing device 9. A centering device 6 is fixedly installed at the bottom of the support device 8. A feeding assembly 7 is installed on one side of the pressing device 9.

[0019] In use, place the pump body on the placement plate 4, then place the impeller in the feeding device. The feeding device automatically presses down to feed the impeller, the support device supports the impeller, the centering device 6 centers the pump body so that the impeller and the shaft of the pump body are aligned, and the clamping device 5 fixes the centered pump body.

[0020] Example 2 like Figure 2 As shown, the clamping device 5 includes a positive and negative lead screw 51 and two sliding rods 52. The positive and negative lead screw 51 is rotatably mounted between two support side plates 2, and the two sliding rods 52 are fixedly mounted between the two support side plates 2, with the two sliding rods 52 distributed on the front and rear sides of the positive and negative lead screw 51. Drive blocks 53 are threaded onto both sides of the outer surface of the positive and negative lead screw 51. A figure-eight rod 54 is fixedly mounted at the end of each of the two drive blocks 53 that is close to each other. A hinge rod 55 is rotatably mounted at both ends of the figure-eight rod 54. An arc-shaped block 56 is fixedly mounted at the end of the hinge rod 55 away from the figure-eight rod 54. A handle 57 is rotatably mounted through one end of the positive and negative lead screw 51 and fixedly mounted thereon. The positive and negative lead screws 51 and the slide rod 52 are both installed through the placement plate 4. The positive and negative lead screws 51 and the placement plate 4 are rotatably connected, and the slide rod 52 is fixedly connected to the placement plate 4. In actual use, the handle 57 is rotated, and the handle 57 drives the positive and negative lead screws 51 to rotate. The rotation of the positive and negative lead screws 51 drives the drive blocks 53 on both sides to move towards the middle, thereby driving the figure-eight rods 54 on both sides to move towards the middle, and then driving the arc-shaped block 56 to approach the pump body and squeeze the pump body. Through the rotating hinge rod 55, it can adapt to pump bodies of different sizes, avoid the pump body moving during the impeller pressing process, which would affect the impeller pressing effect and avoid damage to the impeller due to being too small.

[0021] The clamping device 55 drives two sets of figure-eight linkage mechanisms to move the arc-shaped blocks 56 to firmly hug the pump body shell from both sides by rotating the positive and negative lead screws 51. Its hinged design gives the clamping mechanism a certain degree of self-adaptability, which can be compatible with pump bodies of different sizes and provide continuous and stable locking force during the pressing process. It effectively suppresses the workpiece displacement or vibration that may be caused by the pressing impact, and completely avoids the damage to parts or the decline in assembly quality caused by poor alignment.

[0022] Example 3 like Figure 3-4As shown, the pressing device 9 includes a hydraulic telescopic rod 91 and a working cylinder 92. The hydraulic telescopic rod 91 is fixedly installed at the bottom of the top plate 3, and the working cylinder 92 is fixedly installed at the top of the support device 8. The bottom of the telescopic end of the hydraulic telescopic rod 91 extends through into the working cylinder 92 and is fixedly installed with a baffle 93. A fixed cylinder 94 is fixedly installed at the bottom of the baffle 93. A sliding plate 96 is slidably installed inside the fixed cylinder 94. A spring 95 is fixedly installed at the top of the sliding plate 96. A connecting rod 98 is fixedly installed at the bottom of the sliding plate 96. The bottom of the connecting rod 98 slides through the fixed cylinder 94 and is fixedly installed with an insertion rod 99. A pressing wheel 97 is fixedly installed on the outer side of the bottom of the fixed cylinder 94. The bottom of the working cylinder 92 is open. A rubber ring 910 is fixedly installed in the middle of the outer surface of the insertion rod 99. When the insertion rod 99 moves downward, it is inserted into the shaft hole of the impeller. The rubber ring 910 can increase the friction between the insertion rod 99 and the impeller, preventing the impeller from falling off during the downward movement and affecting subsequent pressing operations.

[0023] In use, the hydraulic telescopic rod 91 drives the working cylinder 92 to move downward, thereby driving the support device 8 and the centering device 6 to move downward. When the centering device 6 is in close contact with the upper end of the pump body, it drives the fixed cylinder 94 to move downward. The working cylinder 92 drives the sliding plate 96, the connecting rod 98, and the insert rod 99 to move downward, driving the insert rod 99 to insert into the shaft hole in the center of the impeller. Then the support device 8 opens, driving the impeller to move downward, passing through the support device 8 and the centering device 6. When the insert rod 99 is in contact with the connecting shaft of the pump body, the fixed cylinder 94 continues to move downward, thereby compressing and contracting the spring 95. The fixed cylinder 94 drives the extrusion wheel to move downward, sliding over the surfaces of the connecting rod 98 and the insert rod 99 to extrude the impeller, pressing the impeller onto the shaft, thus completing the press-fitting of the impeller.

[0024] This invention incorporates multiple safety features during the pressing and feeding processes to ensure smoothness and reliability. The pressing device 9 of this invention is not a simple rigid pressing action. When the insertion rod 99 is first inserted into the impeller shaft hole under the drive of the hydraulic telescopic rod 91, the rubber ring 910 fitted on its exterior significantly increases friction, acting like a soft gripper to ensure that the impeller will not fall off due to gravity or vibration during subsequent movement and the initial pressing stage. When the impeller contacts the pump body shaft and begins to bear pressure, the spring 95 buffer mechanism inside the fixed cylinder 94 begins to function. The sliding compression spring 95 of the slide plate 96 absorbs and dissipates impact energy, and finally, the pressing force is smoothly and gradually transmitted to the impeller through the pressing disc 97, achieving truly smooth pressing. This is crucial for protecting the precision mating surfaces of the impeller and the pump body shaft end.

[0025] The feeding assembly 7 includes a placement cylinder 71 and a rectangular connecting pipe 72. The rectangular connecting pipe 72 is fixedly installed in the middle of the working cylinder 92. The placement cylinder 71 is fixedly installed on the other side of the rectangular connecting pipe 72. The bottoms of the placement cylinder 71 and the rectangular connecting pipe 72 are flush and share a common movable groove 73. Two left-right distributed connecting plates 77 are installed on the front and rear sides of the bottom of the placement cylinder 71 and the rectangular connecting pipe 72. A rotating roller 75 is rotatably installed between the front and rear connecting plates 77 via a rotating shaft 78. A belt 76 is wound around the outer surface of the two rotating rollers 75. A push plate 79 is fixedly installed on the outer surface of the belt 76 and slides in the movable groove 73. A third motor 74 is fixedly installed at the bottom of the placement cylinder 71. The output end of the third motor 74 is fixedly connected to one of the rotating shafts 78.

[0026] In practical use, the impellers are stacked in the placement cylinder 71. When needed, the third motor 74 is started, driving the rotating shaft 78 to rotate. The rotating shaft 78 drives the rotating roller 75 to rotate, which in turn drives the belt 76 to rotate. The belt 76 drives the push rod to move in the movable groove 73, thereby pushing the impeller from the placement cylinder 71 into the rectangular connecting pipe 72, and then into the working cylinder 92. The bottom of the working cylinder 92 is open, and the bottom of the working cylinder 92 has the same inner diameter as the second wheel 81 and the first wheel 61, so that the impeller can smoothly enter the center position of the second wheel 81 and be supported by the support block 85. By moving the push plate 79, the impeller can be automatically pushed into the working cylinder 92, which can automatically complete the feeding work and greatly increase labor efficiency.

[0027] The feeding assembly 7 adopts a belt 76 and pusher plate 79 structure, driven by a third motor 74. It can automatically and sequentially push the impellers stacked in the placement cylinder 71 into the working cylinder 92 and accurately place them on the support device 8. This achieves uninterrupted continuous feeding, freeing operators from repetitive and tedious single loading and unloading work, allowing them to simultaneously manage multiple machines or perform other higher-value tasks, thereby significantly improving per capita production efficiency and reducing idle waiting time in the production cycle.

[0028] A collar 11 is fitted onto the outer surface of the placement cylinder 71. Support rods 10 are fixedly installed on both sides of the collar 11. The end of the support rod 10 away from the collar 11 is fixedly connected to the support side plate 2. The collar 11 restricts the placement cylinder 71. Example 4 like Figure 5-8As shown, the support device 8 includes a second wheel 81, a third wheel 86, and multiple support blocks 85. Multiple first limiting rods 88 are uniformly fixedly installed in a circular array at the bottom of the second wheel 81. Multiple drive grooves 861 are fixedly opened in a circular array at the upper end of the third wheel 86. Slider blocks 89 are fixedly installed at the bottom of the support blocks 85. The multiple support blocks 85 are located between the second wheel 81 and the third wheel 86. The first limiting rods 88 slide within the first sliding grooves 851, and the sliders 89 slide within the drive grooves 861. The third wheel 86 is fixedly mounted with L-shaped plates 87 on all four sides of its upper end, and the second wheel 81 is provided with arc-shaped grooves 811 on all four sides of its upper end. The L-shaped plates 87 slide in the arc-shaped grooves 811. The support device 8 also includes a second gear ring 82 and a second motor 83. The second gear ring 82 is fixedly mounted on the outer surface of the second wheel 81, and the second motor 83 is fixedly mounted on the upper end of the centering device 6. A second gear 84 is fixedly mounted on the output end of the second motor 83, and the second gear 84 and the second gear ring 82 are meshed together.

[0029] In use, at the initial state, multiple support blocks 85 are spliced ​​together to seal the bottom center of the second disc 81. When the impeller enters the middle of the second disc 81, it is supported. When pressing is required, the second motor 83 starts, driving the second gear 84 to rotate. The second gear 84 drives the second gear ring 82 to rotate, which in turn drives the second disc 81 to rotate. The second disc 81 then drives the first limiting rod 88 to rotate, and as the first limiting rod 88 rotates, it slides within the first groove 851. Then, the support block 85 is moved, and the slider 89 at the bottom of the support block 85 slides in the drive groove 861, thereby driving the support block 85 to rotate and open the center bottom of the second wheel 81, so that the second wheel 81 and the third wheel 86 are connected in the center, which facilitates the passage of the impeller. The impeller is supported by the set support device 8, which facilitates the insertion rod 99 to be inserted into the impeller before pressing, so that after the centering device 6 is centered, the impeller shaft hole is aligned with the pump body shaft, which improves the pressing effect of the impeller.

[0030] The adjustable support and opening / closing control functions of the support device 8 of this invention embody sequential intelligence and functional flexibility in its design. It plays distinctly different but crucial roles at different stages of the pressing process. In the initial stage, its multiple support blocks 85 close to form a stable support platform, reliably connecting and positioning the impeller fed from the feeding mechanism. When the pressing command is issued, requiring the impeller to fall, the support device 8, driven by a motor, uses a sophisticated sliding groove and limiting rod mechanism to synchronously and radially retract all support blocks 85, rapidly and neatly opening the central channel like a flower blooming, making way for the impeller's descent. This dynamic and controllable support method perfectly connects the feeding and pressing steps, ensuring a smooth and unobstructed process.

[0031] The centering device 6 includes a first wheel 61 and a third wheel 86 fixedly mounted above the first wheel 61. An annular cavity 62 is formed inside the first wheel 61. An external gear ring 63 is rotatably mounted on the upper part of the inner wall of the annular cavity 62, and a conical gear ring 64 is fixedly mounted on the bottom of the external gear ring 63. Multiple second sliding grooves 621 arranged in a circular array are formed at the bottom of the annular cavity 62. Multiple screws 66 located above the second sliding grooves 621 are rotatably mounted on the inner wall of the annular cavity 62. Movable plates 67 are threaded onto the outer surface of the screws 66, and the bottom of the movable plates 67 slides through the second sliding grooves 621. The groove 621 is fixedly installed with an extrusion block 68. A bevel gear 65 is fixedly installed on one side of the outer surface of the screw 66. The bevel gear 65 meshes with a bevel gear ring 64. A first motor 610 is fixedly installed at the bottom of the annular cavity 62. A first gear 69 is fixedly installed at the top output end of the first motor 610. The first gear 69 meshes with the gear ring. The bottom of the working cylinder 92 is connected to the center of the first wheel 61, the center of the second wheel 81, and the center of the third wheel 86. When the second wheel 81 rotates forward and backward, it can drive multiple support blocks 85 to open and close the center of the second wheel 81.

[0032] In use, the pressing device 9 is activated, driving the centering device 6 to move downwards. When it moves above the pump body, the first motor 610 is activated, driving the first gear 69 to rotate. The first gear 69 drives the outer gear ring 63 to rotate, the outer gear ring 63 drives the conical gear ring 64 to rotate, the conical gear ring 64 drives the conical gear 65 to rotate, the conical gear 65 drives the screw 66 to rotate, and the screw 66 drives the movable plate 67 to slide in the second slide groove 621. Then, it drives the extrusion block 68 to move outwards, extruding the inner edge of the pump body. As a result, under the thrust of multiple outward extrusions, the central shaft of the pump body is located at the center of the first wheel 61, which is below the center of the second wheel 81 and the third wheel 86. This makes the clamping and installation stability of the pump body higher and helps to improve the processing accuracy.

[0033] The centering device 6 of the present invention drives the gear set through the first motor 610, which drives the multiple sets of screws 66-bevel gear mechanism in the annular cavity 62 to move synchronously, so that the multiple extrusion blocks 68 expand radially and uniformly, applying a balanced force to the pump body from the inside, forcing its central shaft to automatically correct itself to a position that is completely coincident with the center line of the device, providing an absolutely accurate reference for the press-fitting of the impeller.

[0034] The working principle of this invention is as follows: In the automatic impeller feeding stage, the operator only needs to stack the impellers in the placement cylinder 71. The third motor 74 drives the rotating roller 75 and belt 76 to operate, causing the push plate 79 to move horizontally along the movable groove 73, sequentially pushing the impellers into the working cylinder 92 through the rectangular connecting pipe 72, and accurately conveying them to the pressing station above the support device 8. This automated feeding process not only eliminates the positional deviation of manual placement but also achieves uninterrupted operation, providing a solid foundation for efficient production.

[0035] In the pump body positioning and clamping stage, after the operator places the pump body on the placement plate 4 in the middle of the base 1, the centering device 6 drives the gear set through the first motor 610, which drives the multiple sets of screws 66-bevel gear mechanisms in the annular cavity 62 to move synchronously. This causes the multiple extrusion blocks 68 to expand radially and uniformly, applying a balanced force to the pump body from the inside. This forces the central shaft to automatically correct itself to a position that is completely aligned with the center line of the device, providing an absolutely precise reference for the impeller press-fitting. The clamping device 5, which follows, drives two sets of figure-eight linkage mechanisms by rotating the positive and negative lead screws 51, causing the arc-shaped blocks 56 to firmly hug the pump body shell from both sides. Its hinged design gives the clamping mechanism a certain degree of self-adaptability, enabling it to accommodate pump bodies of different sizes and providing continuous and stable locking force during the press-fitting process. This effectively suppresses workpiece displacement or vibration that may be caused by press-fitting impact, and completely avoids damage to parts or a decrease in assembly quality due to misalignment.

[0036] During the press-fitting process, the hydraulic telescopic rod 91 advances downward, causing the insertion rod 99 to be inserted into the impeller shaft hole first. The rubber ring 910 set in the middle section of the insertion rod 99 significantly increases the friction between it and the impeller, preventing it from accidentally falling off during movement. As the press-fitting stroke continues, the support device 8 quickly opens the support block 85 under the drive of the motor, and the impeller moves downward under the guidance of the insertion rod 99. When the impeller contacts the pump body shaft, the spring 95 buffer mechanism begins to act, the slide plate 96 slides in the fixed cylinder 94 and compresses the spring 95, and the pressing wheel 97 moves downward accordingly, smoothly pressing the impeller to the target position. This buffer design not only effectively alleviates impact and protects the workpiece surface, but also greatly improves the success rate and quality reliability of the press-fitting process.

[0037] As a key component connecting the pressing and centering systems, the support device 8 features an openable structure that demonstrates excellent timing coordination and functional switching capabilities. Initially, multiple support blocks 85 are closed to form a support plane for connecting and positioning the impeller. Upon receiving the pressing command, the second wheel 81 rotates under the drive of the second motor 83 and the second gear ring 82. Guided by the first limiting rod 88 and the slide groove, it causes the support blocks 85 to synchronously retract radially, rapidly opening the central channel and allowing the impeller to pass smoothly. This dynamic support mechanism achieves stable load-bearing during the feeding stage and ensures interference-free transmission during pressing, further enhancing the continuity and reliability of the entire system.

[0038] In summary, this integrated tooling, with its high degree of integration, automated operation, precise positioning, and flexible clamping, successfully solves problems such as difficult alignment, poor stability, low efficiency, and easy damage to workpieces during impeller pressing. It not only significantly improves assembly accuracy and product consistency but also reduces labor intensity and reliance on operator skills, possessing broad industrial application prospects and high promotional value.
