Description

Technical Field

[0001] This invention relates to the field of speed reducer assembly technology, specifically to an assembly device for speed reducer production. Background Technology

[0002] A speed reducer is a mechanical device that reduces speed and increases output torque through transmission components such as gears and worms. It is widely used in industries, transportation, and energy. Its key components include gears, worms, bearings, end covers, and housings.

[0003] Currently, the existing speed reducer assembly process is as follows: first, assemble the gear assembly, then assemble the gears, shaft, and bearings. The gear assembly is the core of power transmission, and it is necessary to ensure the precise fit between the bearings and the shaft, and between the bearings and the housing. Then, install the worm gear assembly, and finally install the end cover and bearing seal ring.

[0004] In actual operation, when the gear assembly is installed into the housing, bearings are provided at both ends of the shaft of the gear assembly. During the assembly process, the lower bearing of the entire gear assembly is aligned with the pre-reserved circular slot in the housing. Then, a servo press is used to press the entire gear assembly and the lower bearing together into the housing. During this process, extra care must be taken to align the lower bearing with the circular slot in the housing to prevent misalignment.

[0005] In existing technologies, the gear assembly docking process mainly relies on the experience of the workers. The entire gear assembly is placed directly into the housing. During the docking process, the gear assembly may tilt slightly, which will cause the outer ring of the lower bearing to not fully fit with the groove of the housing. After pressing, the pressing force will be concentrated on one edge of the outer ring of the bearing, making it impossible for the lower bearing outer ring to align with the inner ring of the housing, resulting in slight misalignment. This will affect the service life and stability of the entire reducer.

[0006] In addition, the assembly of the speed reducer has high requirements. Operators need to follow the steps one by one. During the assembly process, operators need to maintain fine operation continuously. After working for a long time, visual fatigue and hand muscle soreness are likely to occur, which will lead to a decrease in alignment efficiency later.

[0007] To address the aforementioned issues, there is an urgent need for innovative design based on the existing gearbox assembly device. Summary of the Invention

[0008] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an assembly device for speed reducer production, thereby solving the problems mentioned in the background art, such as the possibility of slight misalignment during the docking process of the lower bearing and the housing, which affects the stability of the speed reducer, and the lack of an automated production line, which leads to a decrease in overall assembly efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an assembly device for producing a speed reducer, comprising an annular slide rail and four equally spaced sliding plates mounted on the annular slide rail, and further comprising two symmetrical arc-shaped clamping pieces mounted in the inner cavity of the sliding plates, wherein the two arc-shaped clamping pieces can automatically slide and converge toward the center and then expand outward to achieve axial positioning and release of the speed reducer bearing; a positioning ring for controlling the sliding path of the two arc-shaped clamping pieces is installed on the outer side of the arc-shaped clamping pieces, and a correction mechanism is provided on the outer side of the positioning ring;

[0010] The inner cavity of the annular slide rail is equipped with a linear slide rail, and a pressure head for applying axial pressure is slidably connected to the linear slide rail.

[0011] Preferably, both of the arc-shaped clamps are disposed in the inner cavity of the positioning ring, and two connecting rods are slidably connected to the inner wall of the positioning ring corresponding to the positions of the two arc-shaped clamps. One end of the connecting rod is slidably connected to a driving rod, and the other end of the connecting rod is fixedly connected to the arc-shaped clamp.

[0012] Preferably, the inner wall of the positioning ring is provided with a guide groove corresponding to the position of the drive rod. The guide groove is bent. One end of the connecting rod passes through the drive rod and is inserted into the inner wall of the guide groove. A gear is fixedly connected to the end of the drive rod. A rack is meshed on one side of the gear. One end of the rack extends to the outside of the positioning ring, and the rack and the positioning ring are connected by a sliding connection.

[0013] Preferably, the length of the lower end face of the arc-shaped clamp is greater than the length of the upper end face, and the upper end face of the arc-shaped clamp is inclined inward. The rotation of the gear drives the drive rod to rotate, which in turn drives the connecting rod to slide along the guide groove, so that it moves synchronously with the arc-shaped clamp.

[0014] Preferably, the correction mechanism includes two symmetrically distributed outer side plates and an inner side plate slidably connected to the outer side plates, and a return spring and a shaft are provided between the outer side plates and the inner side plates;

[0015] Each outer plate has a connecting rod rotatably connected to its bottom, and one end of the connecting rod is rotatably connected to a turntable. The turntable is rotatably connected to the outer wall of the positioning ring.

[0016] Preferably, two swing rods are rotatably connected to the top two sides of the inner side plate, and two protrusions are fixedly connected to the top two sides of the outer side plate, with a straight groove on the surface of each protrusion, and one end of the swing rod slides along the inner wall of the straight groove.

[0017] Preferably, a spring telescopic rod for connecting the rack is installed at the bottom of the outer side plate, and a cylinder is installed on both sides of the inner wall of one of the outer side plates.

[0018] Preferably, a drive motor is mounted on the outer side of the sliding plate, a worm gear is mounted on the output shaft of the drive motor, a worm wheel meshes with the surface of the worm gear, a carrier plate is fixedly connected to the bottom of the positioning ring, and a rotating shaft is fixedly connected between the outer wall of the positioning ring and the worm wheel.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By installing four equally spaced sliding plates on the annular slide rail, multi-station parallel operation can be achieved. The four sliding plates can respectively correspond to the box loading, gear assembly loading, upper end cover positioning and assembly, and bearing seal ring assembly. The outer side of the sliding plate is equipped with a drive motor, worm gear and worm wheel. Utilizing the one-way self-locking characteristics of the worm gear and worm wheel, the box can be accurately rotated and kept stable. The whole structure is a continuous operation. The pressing process does not require manual intervention, which greatly improves assembly efficiency and overall production capacity.

[0021] Meanwhile, two symmetrical arc-shaped clamps are installed at the center of the positioning ring. The two symmetrical arc-shaped clamps are designed with a "long lower end and inwardly inclined upper end" structure, which can form real-time contact with the inner ring of the bearing. Through gear and rack transmission, the connecting rod and drive rod are driven to move, so that the arc-shaped clamps first converge towards the center to limit the inner ring of the bearing. They fit synchronously with the bearing press-fitting, and limit the inner ring of the bearing in real time. Together with the limit of the outer ring of the bearing by the housing hole groove, they form a double constraint inside and outside, reducing the risk of misalignment during docking.

[0022] In addition, the arc-shaped clamping piece is guided by the guide groove on the inner wall of the positioning ring. The overall path of the arc-shaped clamping piece is to slide inward in a straight line first, then pass through the arc section, and gradually slide down until it reaches the lower straight section. It then gradually expands outward until the arc-shaped clamping piece completely leaves the bearing cavity, achieving initial axial positioning. After that, it is gradually released. After the arc-shaped clamping piece leaves the bearing, its upper inclination structure can be transformed into a guide surface. The two expanded arc-shaped clamping pieces can perform secondary centering positioning of the lower bearing seal ring, guiding the seal ring to slide down the lower bearing end face along the arc surface, realizing continuous operation of bearing positioning and seal ring positioning.

[0023] In addition, the cylinder drives the movement of one side of the outer plate, and the turntable drives the two outer plates to move towards the center simultaneously. The inner plate directly presses against the outer shell of the box to achieve uprighting. The swing rod at the top of the inner plate cooperates with the protrusion at the top of the outer plate. When the outer plate moves towards the center for the second time, the protrusion squeezes the swing rod to swing along the straight groove and presses against the upper end cover from both sides to prevent displacement when the pressure head presses down on the upper end cover, thus realizing the integrated operation of the box uprighting shaft and the end cover fixing.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 9The present invention provides a technical solution: an assembly device for producing a speed reducer, including an annular slide rail 1 and four equally spaced sliding plates 2 installed on the annular slide rail 1, and two symmetrical arc-shaped clamping pieces 3 installed in the inner cavity of the sliding plates 2. The two arc-shaped clamping pieces 3 can automatically slide and converge towards the center and then expand outward to realize the axial positioning and release of the speed reducer bearing. A positioning ring 4 is installed on the outer side of the arc-shaped clamping pieces 3 to control the sliding path of the two arc-shaped clamping pieces 3, and a correction mechanism 5 is provided on the outer side of the positioning ring 4.

[0036] The inner cavity of the annular slide rail 1 is fitted with a linear slide rail 6, and a pressure head 7 for applying axial pressure is slidably connected to the linear slide rail 6.

[0037] By installing four equally spaced sliding plates 2 on the annular slide rail 1, multi-station parallel operation can be achieved. The four sliding plates 2 can respectively correspond to the box loading, gear 404 component loading, upper end cover and upper bearing sealing ring assembly, and finally flipping, forming a continuous operation. The pressing process does not require manual intervention, which greatly improves the assembly efficiency.

[0038] Furthermore, during the loading of the gear 404 assembly, dual protection is achieved through the arc-shaped clamping plate 3 and the correction mechanism 5. The correction mechanism 5 automatically corrects and straightens the housing, while the two mutually symmetrical arc-shaped clamping plates 3 limit the lower bearing and simultaneously support and limit it outward. The two arc-shaped clamping plates 3 have the power to automatically converge towards the center and then expand outward. When the lower bearing is initially corrected by the two arc-shaped clamping plates 3, it is aligned with the hole groove of the housing. As the bearing is pressed in, the two clamping plates automatically slide inward and move closer together, limiting the bearing in real time during the assembly process to prevent tilting during pressing.

[0039] In addition, the positioning ring 4 connects the correction mechanism 5 and the arc-shaped clamp 3 respectively. On the one hand, it provides stable support for the box and ensures that the correction mechanism 5 remains stable during the subsequent flipping operation. On the other hand, it controls the sliding path of the arc-shaped clamp 3 in real time to avoid the arc-shaped clamp 3 from deviating during the sliding process.

[0040] In this embodiment, as Figure 2 and Figure 3 As shown, two arc-shaped clamping pieces 3 are both located in the inner cavity of the positioning ring 4. Two connecting rods 401 are slidably connected to the inner walls of the positioning ring 4 on the sides corresponding to the positions of the two arc-shaped clamping pieces 3. One end of the connecting rod 401 is slidably connected to a driving rod 402, and the other end of the connecting rod 401 is fixedly connected to the arc-shaped clamping piece 3.

[0041] In this embodiment, as Figure 6 and Figure 7As shown, a guide groove 403 is provided on the inner wall of the positioning ring 4 corresponding to the position of the drive rod 402. The guide groove 403 is bent. One end of the connecting rod 401 passes through the drive rod 402 and is inserted into the inner wall of the guide groove 403. A gear 404 is fixedly connected to the end of the drive rod 402. A rack 405 meshes with one side of the gear 404. One end of the rack 405 extends to the outside of the positioning ring 4, and the rack 405 and the positioning ring 4 are connected by a sliding connection.

[0042] In this embodiment, as Figure 8 and Figure 9 As shown, the length of the lower end face of the arc-shaped clamp 3 is greater than the length of the upper end face, and the upper end face of the arc-shaped clamp 3 is inclined inward. The rotation of the gear 404 drives the drive rod 402 to rotate, which in turn drives the connecting rod 401 to slide along the guide groove 403, so that it can move synchronously with the arc-shaped clamp 3.

[0043] It should be noted that the positioning ring 4 is installed in the inner cavity of the sliding plate 2 to provide an installation reference for all transmission components. The upper surface of the positioning ring 4 can support the box and provide support for the box. The inner wall of the positioning ring has a bent guide groove 403. The guide groove 403 is bent. The movement path of the arc-shaped clamp 3 is controlled by the bending trajectory of the guide groove 403.

[0044] Specifically, when the arc-shaped clamping pieces 3 are subjected to force and slide towards the center, both arc-shaped clamping pieces 3 are simultaneously subjected to force, further driving the two racks 405 to move relative to each other, simultaneously moving towards the center or simultaneously expanding to both sides. Similarly, when the two racks 405 simultaneously reset, the two gears 404 rotate in opposite directions again, further driving the two drive rods 402 to rotate in opposite directions, causing the two arc-shaped clamping pieces 3 to expand outwards. The two arc-shaped clamping pieces 3 are synchronously displaced, specifically achieving the following functions:

[0045] When the two arc-shaped clamping pieces 3 initially approach each other, the lower bearing of the gear 404 assembly is inserted into the slot of the housing. The slot limits the outer ring of the bearing, and the two arc-shaped clamping pieces 3 limit the inner ring of the bearing. The inner and outer clamping are simultaneously clamped, providing double limiting and reducing the probability of displacement. When the gear 404 assembly is pressed down, the entire lower bearing begins to move downward. During this process, the arc-shaped clamping pieces 3 are squeezed by external force and move towards the center. Since the length of the lower end face of the arc-shaped clamping pieces 3 is greater than the length of the upper end face, and the upper end face of the arc-shaped clamping pieces 3 is inclined inward, the bearing remains in close contact with the inner ring of the bearing during the downward movement, ensuring real-time limiting of the lower bearing.

[0046] In this embodiment, it should also be specifically noted that, as Figure 8As shown, the trajectory of the guide groove 403 on the inner wall of the positioning ring 4 is a straight line inward, then through an arc segment, and then extends outward in a straight line. The overall path of the arc-shaped clamp 3 is a straight line sliding inward, then through the arc segment, disengaging from the inner ring of the bearing, and gradually sliding down until it reaches the lower straight segment, gradually expanding outward until the arc-shaped clamp 3 completely disengages from the inner cavity of the bearing. The guide groove 403 guides the overall trajectory of the arc-shaped clamp 3 to achieve initial axial positioning, and then releases it.

[0047] Furthermore, guided by the middle arc segment, when the arc-shaped clamp 3 separates along the arc trajectory, the contact mode with the inner ring of the bearing changes from surface contact to gradual sliding separation, the contact area gradually decreases, and a certain gap is maintained with the lower end face of the bearing when it completely separates from the inner ring of the bearing. In the final operation, the arc-shaped clamp 3 rotates in the opposite direction synchronously with the housing, and the inward angle of the upper end is transformed into a guide surface at this stage. The two fully expanded arc-shaped clamps 3 perform secondary centering positioning of the bearing seal ring. The bearing seal ring gradually slides inward along the outer ring of the arc-shaped clamp 3 and comes into contact with the bearing end face again, realizing the centering positioning of the bearing seal ring, so that the bearing seal ring and the bearing are coaxially positioned, and continuous assembly is achieved.

[0048] In addition, a vertical rod is slidably connected to the end of the connecting rod 401 away from the arc-shaped clamp 3. The vertical rod is used to control the other end of the connecting rod 401, controlling the vertical sliding of the connecting rod 401. The vertical rod can slide axially along the positioning ring 4, so that the vertical rod can limit the end of the arc-shaped clamp 3 while ensuring that the vertical rod can move back and forth synchronously with the arc-shaped clamp 3, without causing the arc-shaped clamp 3 to get stuck.

[0049] In this embodiment, as Figure 1 As shown, the correction mechanism 5 includes two symmetrically distributed outer plates 501 and an inner plate 502 that is slidably connected to the outer plates 501. A return spring 503 and a shaft are provided between the outer plates 501 and the inner plate 502.

[0050] Each outer side plate 501 has a connecting rod 507 rotatably connected to its bottom, and a turntable 508 is rotatably connected to one end of the connecting rod 507. The turntable 508 is rotatably connected to the outer wall of the positioning ring 4.

[0051] In this embodiment, as Figure 4 and Figure 5 As shown, two swing rods 504 are rotatably connected to the top two sides of the inner side plate 502, and two protrusions 505 are fixedly connected to the top two sides of the outer side plate 501. Each protrusion 505 has a straight groove 506 on its surface, and one end of the swing rod 504 slides along the inner wall of the straight groove 506.

[0052] In this embodiment, as Figure 2 and Figure 9As shown, a spring telescopic rod 509 for connecting the rack 405 is installed at the bottom of the outer side plate 501, and a cylinder 8 is installed on both sides of the inner wall of one of the outer side plates 501.

[0053] It should be noted that the outer side plate 501 and the inner side plate 502 are slidably connected by a shaft. A return spring 503 is sleeved on the outside of the shaft to provide a return force for the subsequent return of the inner side plate 502. Through the connection of the connecting rod 507 and the turntable 508, when one side of the outer side plate 501 is subjected to force and moves towards the center, the turntable 508 rotates, causing the other side of the outer side plate 501 to move inward at the same time, further causing the two inner side plates 502 to move synchronously and straighten the box.

[0054] In addition, through the connection of the spring telescopic rod 509, when the outer side plate 501 and the inner side plate 502 remain static, the spring telescopic rod 509 can automatically stretch, and at the same time provide damping for the two arc-shaped clamps 3, preventing the arc-shaped clamps 3 from moving too far towards the center, and making the axial positioning of the bearing inner ring more stable.

[0055] In addition, such as Figure 3 As shown, a swing rod 504 is added to the top of the outer side plate 501. When the inner side plate 502 abuts against the box, the cylinder 8 is activated again to move the outer side plate 501 towards the center for the second time. At this time, the position of the inner side plate 502 remains fixed. The protrusion 505 squeezes the swing rod 504 to swing towards the center, clamping and limiting the top end cap. During the pressing process of the pressure head 7, the end cap is prevented from shifting.

[0056] In this embodiment, as Figure 3 As shown, a drive motor 201 is installed on the outer side of the sliding plate 2, a worm gear 202 is installed on the output shaft of the drive motor 201, a worm wheel 203 is meshed on the surface of the worm gear 202, a carrier plate 9 is fixedly connected to the bottom of the positioning ring 4, and a rotating shaft is fixedly connected between the outer wall of the positioning ring 4 and the worm wheel 203.

[0057] It should be noted that by utilizing the unidirectional transmission characteristics of the worm gear 202 and worm wheel 203, the positioning ring 4 and the entire carrier plate 9 are self-locked. The worm gear 202 is rotated by the drive motor 201, which in turn drives the worm wheel 203, the positioning ring 4, and the entire housing to rotate 180°, thus opening the assembly of the bottom bearing seal ring. The transmission process of the worm gear 202 and worm wheel 203 is a deceleration transmission. During the adjustment process, a small adjustment is achieved to avoid excessive adjustment during the overall rotation.

[0058] In addition, the transmission through the worm gear 203 and worm 202 provides stronger anti-interference capability. During press-fitting, the axial force applied by the press head 7 may be transmitted to the positioning ring 4 through the bearing and the arc-shaped clamp 3. However, the self-locking torque of the worm gear 202 and worm wheel 203 is large, which can offset the torque, ensuring that the positioning ring 4 does not rotate and that the positioning ring 4 is always in a balanced state, reducing the risk of the positioning ring 4 tilting or shifting.

[0059] Working principle: When using this assembly device, first place all the parts, and then gradually feed them by the feeding robot. The feeding robot can be installed on one side of the circular slide rail 1. The arc slide rail is activated to realize directional conveying and fixed-point parking. This process is existing technology and will not be elaborated on in detail.

[0060] Box loading: Place the unassembled box into the center of the positioning ring 4 of the first sliding plate 2. There are four sliding plates 2 in total. As the first sliding plate slides backward, the second sliding plate continues to load the box.

[0061] During the placement of the box, align the slot on the lower end face of the box with the arc-shaped clamp 3, so that the arc-shaped clamp 3 initially fits against the inner wall of the slot in the box. At the same time, start the cylinder 8. The piston rod of the cylinder 8 pulls one of the outer plates 501 inward. During this process, push the spring telescopic rod 509 and the rack 405 to slide inward at the same time. At this time, the two racks 405 approach each other, pushing the two gears 404 to rotate in opposite directions, pushing the two arc-shaped clamps 3 towards the center. The two arc-shaped clamps 3 approach each other until the inner side plate 502 abuts against the outer shell of the box, straightening the box.

[0062] Feeding the Gear 404 assembly: Align the lower bearing of the Gear 404 assembly with the slot at the bottom of the housing and insert it. Place the outer ring of the lower bearing against the upper half of the slot and the inner ring against the outer wall of the arc-shaped clamp 3. The arc-shaped clamp 3 guides the entire Gear 404 assembly to automatically find the center and achieves internal and external centering limit. At this time, the outer ring of the bearing is slightly convex and the entire arc-shaped clamp 3 is also at the highest position. Apply axial pressure through the pressure head 7 to make the entire Gear 404 assembly move vertically downward, further driving the lower bearing to gradually slide down along the slot of the housing. During the downward movement of the lower bearing, the two arc-shaped clamps 3 in the inner cavity are continuously squeezed. Under the action of the two connecting rods 507, the two arc-shaped clamps 3 are subjected to the force of the two outer plates 501 and move towards the center at the same time.

[0063] During this process, as the arc-shaped clamp 3 slides inward and moves closer together, the positions of the outer side plate 501 and the inner side plate 502 remain unchanged, and the spring telescopic rod 509 begins to stretch. The spring telescopic rod 509 provides reverse resistance, making the sliding process of the arc-shaped clamp 3 smoother.

[0064] Upper cover fixing: When the gear 404 assembly is fully embedded in the housing, the lower bearing is fully embedded in the slot of the housing. At this time, the cylinder 8 is started again. The piston rod of the cylinder 8 pulls the outer plate 501 towards the center for the second time, further squeezing the inner plate 502. At this time, the inner plate 502 is pressed against the outer shell of the housing and remains stationary. The ends of the two swing rods 504 slide along the straight groove 506 and swing towards the side, fixing the upper cover from both sides.

[0065] Furthermore, during this process, as the outer side plate 501 gradually slides closer together, it pushes the spring telescopic rod 509 and the rack 405, further pushing the gear 404 to continue rotating, causing the drive rod 402 to rotate again, which in turn moves the connecting rod 401 to slide along the guide groove 403. As the gear 404 continues to rotate, the connecting rod 401 pushes the arc-shaped clamp 3, causing the arc-shaped clamp 3 to gradually slide down along the inner ring of the lower bearing, and then move backward, gradually disengaging from the lower bearing. At this point, the upper cover is assembled, and the arc-shaped clamp 3 at the lower end is also disengaged from the lower bearing.

[0066] Bearing seal assembly: First, install the bearing seal on the upper bearing. Align the bearing seal with the upper bearing and press it down using the pressure head 7. Then, start the drive motor 201 to rotate the worm gear 202 and worm wheel 203. The worm wheel 203 drives the rotating shaft to rotate, which in turn drives the entire carrier plate 9 and positioning ring 4 to rotate. At this time, the upper swing rod 504 holds the housing and the upper cover together. Together with the inner side plates 502 on both sides, it prevents the housing from tilting and falling during rotation. The arc-shaped clamp 3 rotates synchronously in the opposite direction to the housing. The inward tilt angle of the upper end is at this stage. The section is transformed into a guide surface, which places the lower bearing seal ring into the two arc-shaped clamps 3. The bearing seal ring gradually moves towards the center along the inner wall of the arc-shaped clamps 3, so that the lower bearing seal ring and the lower bearing of the shaft are coaxially positioned. Then, it is squeezed by the pressure head 7. At this time, the pressure head 7 has relatively small pressure when assembling the seal ring. The swing rod 504 that previously fixed the upper cover continues to press against the upper cover, and the inner side plates 502 on both sides are still close to the outer shell of the box. The two form a cooperative constraint from the top and bottom and inside and outside directions, which temporarily supports and limits the box to ensure that the box does not shift.

[0067] Finally, the drive motor 201 is started to reverse, flipping the entire box over again. The cylinder 8 is started, and the piston rod of the cylinder 8 pushes the outer plate 501 to reset. The reset spring 503 simultaneously pushes the inner plate 502 and the swing rod 504 to reset. At the same time, the rack 405 is pulled to reset by the spring telescopic rod 509, which drives the gear 404 to rotate in the opposite direction, further retracting the arc-shaped clamp 3 to its original position. The box is then pulled upwards and unloaded, and a new unassembled box is placed for a new round of operation.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
