Abstract
Description
Technical Field
[0001] This invention relates to the field of rotor manufacturing technology, and more specifically to a water pump rotor bearing assembly device. Background Technology
[0002] Rotor bearing press-fitting machines are currently widely used motor bearing installation mechanisms. Traditional bearing press-fitting machines typically use a fixed-shaft press-fitting mechanism to press the rotor and bearing together. First, the shaft is fixed to a fixture, then the bearing outer ring is clamped using a clamping mechanism, and finally, hydraulic pressure is used to force the bearing onto the shaft, thus fixing the shaft and bearing. Existing rotor bearing press-fitting devices generally use a rotary feeding method. This rotary feeding method requires many moving parts, resulting in high assembly and maintenance difficulty and a high parts wear rate, affecting feeding efficiency. Furthermore, the rotor fixing method is complex, and the coordination efficiency with the robotic arm is low, impacting work efficiency in actual operation.
[0003] For example, the "Rotor Bearing Press-fitting Device" disclosed in Chinese patent literature, publication number CN215787975U, includes a fixed bracket with a worktable on the fixed bracket. Its distinguishing feature is that it also includes a bearing feeding device, a bearing press-fitting machine, and a rotor frame. The bearing feeding device, bearing press-fitting machine, and rotor frame are all fixed on the worktable. Pairs of slide rails are provided on the worktable. The bearing press-fitting machines are arranged in pairs, with the pairs of bearing press-fitting machines positioned on both sides of the rotor frame. Each bearing press-fitting machine includes a bearing mounting seat for fixing the bearing and a press-fitting pushing assembly for pushing the bearing mounting seat. The bearing mounting seat is slidably mounted on the slide rails. Summary of the Invention
[0004] To address the technical problems of low material feeding efficiency, high assembly and maintenance difficulty, high parts loss rate, and low coordination efficiency between the rotor fixing method and the robotic arm in existing rotor bearing press-fitting devices, this invention provides a water pump rotor bearing assembly device. It improves material feeding efficiency and coordination efficiency with the robotic arm, significantly improves overall work efficiency, and reduces assembly and maintenance difficulty and parts loss rate.
[0005] Technical solution
[0006] To solve the above problems, the technical solution provided by the present invention is as follows:
[0007] A water pump rotor bearing assembly device includes a discharge section comprising a plurality of feed cylinders arranged in a straight line and a discharge trough disposed along the outlet of the feed cylinders. The discharge trough is equipped with a discharge claw for pushing the bearings, and a pusher plate for uniformly pushing the bearings is disposed at the outlet of the feed cylinders. A loading section comprises a loading structure and a moving structure. The loading structure moves along a planned path of the moving structure and is linked to the discharge section and the pressing section along the moving path. The pressing section comprises a rotor fixing structure and a pressing structure. The rotor fixing structure comprises a movable fixing fixture and a support block. The movable fixing fixture includes a movable pressing block located above. The pressing block and the support block are movably adapted to each other and have a notch in the middle for accommodating the rotor.
[0008] The linear arrangement of the feed cylinders and discharge chute design enables orderly and efficient bearing supply by arranging the feed cylinders in a straight line and directly connecting them to the discharge chute. This design simplifies the bearing conveying process, reduces jamming or misalignment of bearings during transfer, and improves the continuity and stability of the feeding process.
[0009] Application of discharge claws and pusher plates: The discharge claws ensure that the bearings are precisely pushed into the discharge chute and ultimately reach the assembly position, reducing the need for manual intervention and improving assembly accuracy. The uniform pushing mechanism of the pusher plates further guarantees the consistency of the pushing action and the control of force, avoiding unnecessary damage to the bearings. The pushing efficiency is significantly improved compared to traditional discharge methods.
[0010] The ingenious design of the pressing section: the cooperation between the movable fixing fixture and the support block in the rotor fixing structure, especially the notch design between the pressing block and the support block that can accommodate the rotor, not only ensures the accurate positioning of the rotor during the pressing process, but also allows the robotic arm to grab the rotor from above, which is direct and efficient. Compared with the traditional top and bottom clamping method, which requires clamping from the side and has a winding path, the top gripping method of this solution has a straight up and down path, which greatly improves efficiency compared with the traditional method.
[0011] Alternatively, the feed cylinder may be positioned at an angle.
[0012] With the feed cylinder tilted, the weight of the bearing forms a component force, which greatly reduces the pressure on the bottom bearing of the feed cylinder. This reduces resistance when the pusher plate pushes the feed cylinder, preventing jamming. Furthermore, with the feed cylinder tilted, the bearing exerts pressure on the side wall of the feed cylinder, resulting in friction between the bearing and the feed cylinder. This slows down the bearing as it falls, preventing it from colliding and being damaged.
[0013] Optionally, the outlet of the feeding cylinder is provided with a pusher plate perpendicular to the feeding cylinder, the pusher plate moves along the vertical direction of the feeding cylinder, and the external guide structure of the pusher plate is connected to the discharge trough.
[0014] The pusher plate is used to push the fallen bearings to the discharge chute.
[0015] Optionally, the outlet of the discharge trough is connected to a material leakage port, and a material removal area is provided below the material leakage port to cooperate with and connect with the feeding structure.
[0016] The material discharge port is used to receive a single bearing pushed laterally by the discharge claw. The material waiting area receives the single bearing that falls below the material discharge port, and then the feeding structure clamps it to the pressing part for pressing.
[0017] Optionally, the material receiving area is provided with a drive mechanism for axially pushing the bearing.
[0018] The drive mechanism pushes the bearing axially from the bearing.
[0019] Optionally, both the feeding section and the pressing structure are provided with a left side structure and a right side structure, and the bearings are pressed together on both sides of the rotor.
[0020] The rotor is pressed together on both sides simultaneously, which greatly improves efficiency.
[0021] Optionally, the left side structure of the pressing structure includes a left pressing fixture, the end of which is provided with a protrusion adapted to the bearing. The protrusion is arranged vertically and is arc-shaped. The right side structure of the pressing structure includes a right pressing fixture, which has the same structure as the left pressing fixture.
[0022] The bumps can perfectly fit the bearings, ensuring that the bearings are not easily dropped and that the feeding is stable.
[0023] Optionally, the feeding structure is provided with a feeding fixture, which has grippers located on both horizontal sides. The grippers cooperate with the protrusions, and the gap between the grippers is used for the passage of the protrusions.
[0024] The grippers are compatible with the bumps. When the bearing is loaded onto the bumps, the grippers can be released to place the bearing onto the bumps, ensuring stability and high efficiency.
[0025] Optionally, the left side structure of the feeding section is a left feeding section, including a left feeding fixture, a rotating seat, a fixture drive mechanism, a left feeding moving seat, a left feeding guide rail, and a left moving drive mechanism. The rotating seat is rotatably connected to the fixture drive mechanism through a transmission structure. The left feeding fixture is fixedly connected to the rotating seat. The left feeding fixture, the rotating seat, and the fixture drive mechanism are all fixedly connected to the left feeding moving seat. The left feeding moving seat is slidably connected to the left feeding guide rail and connected to the left moving drive mechanism.
[0026] The flexibility of the loading section: The combination of the loading and moving structures, especially the ability of the loading structure to move along a planned path, greatly improves the flexibility and efficiency of loading. This design allows the device to adapt to different working scenarios and production line layouts, while also facilitating seamless integration with other automated equipment (such as robotic arms), enhancing the overall automation level of the system. The structure of the loading section on the right is similar to that on the left.
[0027] Optionally, a vision inspection unit is provided next to the left feeding guide rail, with the lens of the vision inspection unit facing the left feeding guide rail. A diffuse reflection plate is provided on the other side of the left feeding guide rail, with the lens facing the diffuse reflection plate.
[0028] Visual inspection fixtures are used to check the orientation of bearings and to check whether the bearing structure is normal.
[0029] Beneficial effects
[0030] Compared with the prior art, the technical solution provided by this invention has the following advantages:
[0031] The technical solution provided by this invention includes a discharge section, comprising a plurality of feed cylinders arranged in a straight line and a discharge trough disposed along the outlet of the feed cylinders. The discharge trough is equipped with discharge claws for pushing bearings, and a pusher plate for uniformly pushing bearings is provided at the outlet of the feed cylinders. The design of the straight-lined feed cylinders and discharge troughs achieves orderly and efficient bearing supply by arranging the feed cylinders in a straight line and directly connecting them to the discharge trough. This design simplifies the bearing conveying process, reduces jamming or misalignment of bearings during transfer, and improves the continuity and stability of the feeding. The discharge speed depends on the number of feed cylinders; the more feed cylinders, the higher the efficiency of the pusher plate. Bearings in the discharge trough only require lateral pushing by the discharge claws, and the discharge will not stop. In this case, the feeding speed depends only on the speed of the feeding section.
[0032] The pressing section includes a rotor fixing structure and a pressing structure. The rotor fixing structure includes a movable fixing fixture and a support block. The movable fixing fixture includes a movable pressing block located above. The pressing block and the support block are movably adapted to each other and have a notch in the middle for accommodating the rotor. The cooperation between the movable fixing fixture and the support block in the rotor fixing structure, especially the design of the notch between the pressing block and the support block to accommodate the rotor, not only ensures the accurate positioning of the rotor during the pressing process, but also allows the robotic arm to grasp the rotor from above, which is direct and efficient. Compared with the traditional top and bottom clamping method, which requires clamping from the side and has a winding path, the top gripping method of this solution has a straight up and down path, which greatly improves efficiency compared with the traditional method.
[0033] Through the aforementioned design, this device significantly improves the efficiency of material loading and assembly, reduces manual operation, and lowers the assembly error rate. Simultaneously, by reducing manual operation, it also reduces maintenance difficulty and parts wear caused by human factors, effectively saving costs and improving production efficiency and product quality in the long run.

[0046] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. Example
[0047] Combined with appendix Figure 1 , 2 A water pump rotor bearing assembly device includes a discharge section 1, a pressing section 2, a left-side loading section 3, a visual inspection section 4, and a right-side loading section 5. A left-side bearing 7, a rotor 8, and a right-side bearing 9 are located on the pressing section 2. All components are located on a base plate. Two discharge sections 1 are provided, arranged side-by-side, to supply bearings to the left and right sides of the rotor 8, respectively. The left-side loading section 3 is connected to the left side of the left discharge section 1 and the left side of the pressing section 2, and the right-side loading section 5 is connected to the right side of the right discharge section 1 and the right side of the pressing section 2. The left-side loading guide rail 306 of the left-side loading section 3 is perpendicular to the discharge section 1, and the right-side loading guide rail 503 of the right-side loading section 5 is parallel to the discharge section 1. The movement of the right-side loading section 5 perpendicular to the discharge section 1 is achieved by the rotation of the right-side connecting plate 505, as shown in the attached diagram. Figure 10As shown. The pressing section 2 is arranged parallel to the discharge section 1. The vision inspection section 4 is located on both sides of the left-side feeding guide rail 306, and detects the orientation of the bearings during the feeding process. The bearings are distinguished by orientation, and some bearings (such as angular contact ball bearings) have orientation requirements when installed with the rotor 8. The components are distributed reasonably and centrally, saving space and reducing the bearing movement distance, thus improving work efficiency.
[0048] Combined with appendix Figure 3 , 4 The discharge section 1 includes several feed cylinders 101 arranged in a straight line and a discharge chute 102 arranged along the outlet of the feed cylinders 101. The discharge chute 102 is equipped with a discharge claw 105 for pushing the bearings. The outlet of the feed cylinders 101 is provided with a pusher plate 1012 for uniformly pushing the bearings. In this embodiment, there are 8 feed cylinders 101, and each feed cylinder 101 has an upward-facing opening 103 to facilitate observation of the bearings inside the feed cylinder 101, and the bearings can be moved through the opening 103.
[0049] The feed cylinder 101 is tilted. The gravity of the bearing forms a component force, greatly reducing the pressure on the bottom bearing of the feed cylinder 101. This reduces resistance during the pushing process by the pusher plate 1012, preventing jamming. Furthermore, with the feed cylinder 101 tilted, the bearing exerts pressure on the side wall of the feed cylinder 101, creating friction between the bearing and the feed cylinder 101, thus slowing down the bearing's descent. The top of the opening 103 of the feed cylinder 101 is also provided with a flush inlet for placing the bearing. This inlet facilitates placement, prevents the bearing from easily falling out, and avoids the bearing from flipping inside the feed cylinder 101.
[0050] The outlet of the discharge trough 102 is connected to a discharge port 104, and a material collection point is provided below the discharge port 104 to cooperate with the feeding structure. The discharge port 104 is scoop-shaped, with the smaller opening facing down and the larger opening facing up. After the bearing is removed from the discharge trough 102, it falls through the discharge port 104 to the material collection point below. The material collection point is provided with a pushing mechanism 108 for axially pushing the bearing. The aforementioned pushing mechanism 108 is a cylinder for pushing.
[0051] Combined with appendix Figure 4 , 5 The outlet of the feeding cylinder 101 is provided with a pusher plate 1012 perpendicular to the feeding cylinder 101. The pusher plate 1012 moves along the vertical direction of the feeding cylinder 101, and the external guide structure of the pusher plate 1012 is connected to the discharge trough 102. The pusher plate 1012 is fixed to the pusher rod 1013, which passes through the guide seat 109. The guide seat 109 limits the pusher rod 1013, and the reciprocating movement of the pusher rod 1013 drives the pusher plate 1012 to push the bearing. The pusher rod 1013 is connected to a cylinder, which is located below the base plate.
[0052] The discharge claw 105 is L-shaped and covers the width of the discharge trough 102. A protruding claw is located at the lower end of the discharge claw 105, which overlaps the side of the bearing to drive its movement. The discharge claw 105 is fixed to the discharge moving seat 106, which is connected to the discharge screw 107. The discharge moving seat 106 has a threaded hole, and the discharge screw 107 is connected to a discharge drive motor 1010 located on the right side. The rotation of the discharge screw 107 controls the movement of the discharge claw 105.
[0053] Combined with appendix Figure 6 , 7 The pressing part 2 includes a rotor 8 fixing structure and a pressing structure. The rotor 8 fixing structure includes a movable fixing fixture 2010 and a support block 201004. The movable fixing fixture 2010 includes a movable pressing block 201003 located above. The pressing block 201003 and the support block 201004 are movably adapted to each other and have a notch in the middle for accommodating the rotor 8.
[0054] The left pressing frame 201 is equipped with a cylinder for pushing. The cylinder is connected to the left pressing moving seat 203 via a left linkage rod 204. A left pressing fixture 205 is fixedly connected to the left pressing moving seat 203. The end of the left pressing fixture 205 is provided with a protrusion adapted to the bearing. The protrusion is arranged vertically and is arc-shaped. The right side structure of the pressing structure includes a right pressing fixture 208, which has the same structure as the left pressing fixture 205. The right pressing moving seat 207 is located on the right side and connected to the right pressing fixture 208. The right pressing fixture 208 is connected to a right drive mechanism 209, which is a cylinder.
[0055] Combined with appendix Figure 7 A rotating motor 201001 is mounted on the fixed base 206. The rotating motor 201001 is connected to the pressure block 201003 via a rotating rod 201002. The rotating rod 201002 can rotate around the output shaft of the rotating motor 201001, causing the pressure block 201003 to move away. The rotor 8, which was originally limited by the pressure block 201003 above the support block 201004, can now be easily and quickly grasped up and down by the robotic arm after it is moved away. After the rotor 8 without bearings is placed, the rotating rod 201002 is rotated back, and the support block 201004 and the pressure block 201003 form a limiting position.
[0056] Combined with appendix Figure 8 The feeding section includes a feeding structure and a moving structure. The feeding structure moves along a path planned by the moving structure, and the feeding structure is linked with the discharging section 1 and the pressing section 2 along the moving path.
[0057] Both the feeding section and the pressing structure are provided with a left side structure and a right side structure, and the bearings are pressed together on both sides of the rotor 8.
[0058] The feeding structure is equipped with a feeding fixture, which has grippers located on both horizontal sides. The grippers engage with the protrusions, and the gap between the grippers allows the protrusions to pass through. The grippers are connected to a small cylinder, which can open and close the grippers to clamp or release the bearing.
[0059] The left side structure of the feeding section is the left feeding section 3, which includes a left feeding fixture 301, a rotating seat 302, a fixture drive mechanism 303, a left feeding movable seat 305, a left feeding guide rail 306, and a left moving drive mechanism 307. The rotating seat 302 is rotatably connected to the fixture drive mechanism 303 via a transmission structure. The left feeding fixture 301 is fixed to the rotating seat 302. The left feeding fixture 301, the rotating seat 302, and the fixture drive mechanism 303 are all fixed to the left feeding movable seat 305. The left feeding movable seat 305 is slidably connected to the left feeding guide rail 306 and connected to the left moving drive mechanism 307. The left feeding movable seat 305 has a threaded hole connected to a lead screw, which controls the movement of the left feeding movable seat 305. The left moving drive mechanism 307 is a motor connected to the lead screw. The tooling drive mechanism 303 is a motor, which is connected to the rotating seat 302 at the bottom via a belt 304, thereby enabling the rotation of the left-side loading tooling 301. The tooling drive mechanism 303 is electrically connected to the controller via a cable chain.
[0060] Combined with appendix Figure 9 A vision inspection unit 4 is provided next to the left feeding guide rail 306. The lens 401 of the vision inspection unit 4 is directly facing the left feeding guide rail 306. A diffuse reflection plate 402 is provided on the other side of the left feeding guide rail 306. The lens 401 is opposite to the diffuse reflection plate 402.
