Description

Technical Field

[0001] This application relates to the technical field of bearing cage processing equipment, specifically to a feeding and positioning fixture for punching holes in tapered bearing cage blanks. Background Technology

[0002] Tapered roller bearings, as a key component widely used in various mechanical equipment, directly affect the operational stability and service life of the equipment due to their performance. The cage of a tapered roller bearing is an important part of the bearing; its function is to maintain the proper spacing between the rolling elements, guide their movement, and ensure smooth and efficient bearing operation. Punching is a crucial process in the manufacturing of tapered roller bearing cages. Through punching, specific holes are formed in the cage blank to accommodate the rolling elements. Because punching requires precise control of the blank's rotation angle, a locating hole is usually provided on the bottom wall of the blank. This hole mates with a locating structure on the punching fixture, providing an accurate positional reference for the cage blank's installation in the punching fixture. This ensures the cage blank is installed in the correct orientation, guaranteeing the positional accuracy of subsequent punching.

[0003] Traditionally, manual feeding is used to load the cage blanks into the punching fixture and align the positioning holes with the positioning structures on the fixture. However, manual feeding is inefficient. With the development of mechanical automation, automated feeding is gradually replacing traditional manual feeding. One type of automated feeding involves pre-transporting the cage blank to a loading platform via a conveyor belt, and then using a robotic arm to pick it up from the loading platform and transfer it to the punching fixture. This method has some drawbacks: when the conveyor belt transports the cage blank to the loading platform, it cannot precisely control the placement angle of the cage blank; it can only roughly push the cage blank to the loading platform. Due to inertia, the positioning hole angles of the cage blank are randomly distributed. After the robotic arm picks up the cage blank, it cannot quickly and accurately align the positioning holes with the positioning structures on the punching fixture. It requires complex path planning to adjust the blank's posture or continuously adjusting the position of the positioning structures to match the positioning holes on the blank, which takes a long time, severely slowing down the feeding speed and reducing production efficiency. Utility Model Content

[0004] This application provides a feeding and positioning fixture for punching holes in tapered bearing cage blanks, which effectively solves the technical problem that the feeding speed is severely slowed down during the feeding process of existing tapered bearing cage blanks to punching fixtures due to the long time spent adjusting the posture of the robot or the position of the positioning structure.

[0005] The technical solution adopted in this application is as follows:

[0006] A loading and positioning fixture for punching holes in tapered bearing cage blanks, wherein the tapered bearing cage blank includes a bottom wall and a tapered side wall, and an eccentrically positioned positioning hole is provided on the bottom wall. The loading and positioning fixture includes a base, a rotating device, and an identification device. The base is provided with a loading platform for accommodating the tapered bearing cage blank, and the loading platform is provided with a rotating station. The rotating device can drive the tapered bearing cage blank located at the rotating station to rotate in order to adjust the position of the positioning hole. When the rotating device adjusts the positioning hole to the position identified by the identification device, it stops rotating the tapered bearing cage blank.

[0007] This technical solution fundamentally solves the problem of low positioning efficiency caused by the random angle of tapered bearing cage blanks in automated conveying by linking the rotating device and the identification device. Traditional conveyor belts can only achieve coarse positioning of tapered bearing cage blanks, while this application adds an active rotation adjustment function at the end of the conveyor, so that tapered bearing cage blanks with any angle input can be dynamically corrected to the target angle at the rotating station. This allows the robot arm to remove tapered bearing cage blanks with a fixed placement posture from the rotating station. Only by setting the positioning structure in a certain position for the punching fixture according to the placement posture can the positioning hole and the positioning structure be quickly and accurately matched, eliminating the time-consuming steps of adjusting the robot arm posture or the tooling positioning structure. The real-time feedback of the identification device reduces the positioning time of a single operation from tens of seconds in traditional automation solutions to less than 10 seconds or even 5 seconds, without the need for machine downtime intervention, directly improving the production line cycle time.

[0008] The loading platform is provided with a through hole corresponding to the rotating station. The rotating device can be raised and lowered to have a clearance position and a working position. When the rotating device is in the clearance position, it is lower than the through hole. When the rotating device is in the working position, it passes through the through hole and can drive the tapered bearing cage blank to rotate.

[0009] In this technical solution, the design of the adjustable rotating device and the through hole solves the problem of spatial interference between the rotating device and the tapered bearing cage blank during loading. In traditional solutions, a fixed rotating device would obstruct the sliding path of the tapered bearing cage blank on the conveyor platform, forcing the use of complex segmented conveying or robotic arm gripping and obstacle avoidance. This application, through a lifting and obstacle avoidance mechanism, allows the rotating device to be completely hidden under the loading platform during non-working periods, and the conveyor belt can continuously and linearly transport the blank to the rotating station, eliminating the angle correction action in the robotic arm gripping path and significantly improving the loading speed.

[0010] The rotating device includes a rotary motor and a force transmission shaft fixed on the rotary output shaft of the rotary motor. The rotary motor drives the tapered bearing cage blank to rotate through the force transmission shaft.

[0011] In this technical solution, the direct-drive structure of the rotary motor and the force transmission shaft overcomes the inertial offset defect during the rotation of the robotic arm. When a traditional robotic arm grips and rotates a blank, the gap between the grippers causes the center of rotation to drift, resulting in secondary positioning errors.

[0012] The force transmission shaft includes a thin shaft section and a thick shaft section from top to bottom. The center of the bottom wall is provided with a fitting hole adapted to the thin shaft section. When the thin shaft section is fitted with the fitting hole, the thick shaft section abuts against the bottom surface of the bottom wall.

[0013] In this technical solution, the stepped design of the thin shaft section and the thick shaft section achieves a dual function: the interference fit between the thin shaft section and the mating hole ensures that the power transmission is free from slippage, while the surface contact between the end face of the thick shaft section and the bottom surface of the blank forms an axial limit, preventing the blank from moving axially during rotation. In addition, the thick shaft section can lift the tapered bearing cage blank upwards by a certain distance, reducing the mutual interference between tapered bearing cage blanks.

[0014] A lifting cylinder is installed on the base, and the lifting cylinder is used to drive the rotating device to rise and fall.

[0015] In this technical solution, the linear drive method of the lifting cylinder has a faster response speed compared to the lead screw module, and achieves a soft landing through pneumatic buffering, avoiding micro-displacement of the blank caused by rigid impact. The lifting cylinder has a built-in magnetically coupled position sensor that can monitor the lifting stroke in real time, forming a linkage control with the rotation device to ensure that the rotation action is initiated only after the lifting is in place, preventing mechanical interference.

[0016] The cylinder body of the lifting cylinder is located below the loading platform, and the piston rod of the lifting cylinder is provided with a mounting plate. The rotating device is fixedly mounted on the mounting plate.

[0017] In this technical solution, the layout of the lifting cylinder can effectively hide the rotating device under the loading platform and drive the rotating device to move, and also facilitates the assembly of the rotating device.

[0018] The feeding platform is provided with a feeding limiting slide that accommodates and guides the tapered bearing cage blank to move in a straight line. The first end of the feeding limiting slide is open to allow the tapered bearing cage blank to enter. The rotating station is located at the second end of the feeding limiting slide, and the second end is closed to stop and limit the tapered bearing cage blank at the rotating station.

[0019] In this technical solution, the feeding limit slide specifically addresses the problem of disordered posture of the tapered bearing cage blank at the end of the conveyor belt, causing the tapered bearing cage blank to move in a straight line toward the rotating station, providing a pre-alignment reference for subsequent rotation positioning, and significantly reducing rotation time.

[0020] The identification device is mounted on the base and located directly above the rotating station.

[0021] In this technical solution, the vertical detection optical path is arranged directly above the identification device. Compared with oblique detection, this can eliminate the perspective distortion caused by the tapered sidewall of the tapered bearing cage blank, which greatly improves the identification accuracy of the positioning hole edge and effectively enhances the accuracy of the identification device in detecting the position of the positioning hole.

[0022] The base includes an upright plate, the feeding platform is fixed to one side of the upright plate, the upright plate is provided with a fixing plate located above the feeding platform, and the identification device is installed on the fixing plate.

[0023] In this technical solution, the upright plate, the feeding platform, and the fixing plate form a frame structure, which is simple and facilitates the installation of accessories.

[0024] The identification device is a visual inspection device equipped with a camera.

[0025] In this technical solution, the technical bottleneck of difficulty in identifying positioning holes in reflective material blanks can be overcome by using deep learning algorithms of visual inspection equipment, thereby improving the accuracy of positioning hole position identification.

[0026] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least the following: Through the linkage control of the rotating device and the identification device, the problem of low positioning efficiency caused by the random angle of the tapered bearing cage blank in automated conveying is fundamentally solved. Traditional conveyor belts can only achieve coarse-grained positional conveying of tapered bearing cage blanks. This application adds an active rotation adjustment function at the end of the conveyor, enabling tapered bearing cage blanks input at any angle to be dynamically corrected to the target angle at the rotating station. This allows the robot arm to remove tapered bearing cage blanks with a fixed placement posture from the rotating station. Only by setting the positioning structure in a specific position for the punching fixture according to this placement posture can the positioning hole and positioning structure be quickly and accurately matched, eliminating the time-consuming steps of robot arm posture adjustment or fixture positioning structure adjustment. The real-time feedback from the identification device reduces the single positioning time from tens of seconds in traditional automation solutions to less than 10 seconds or even 5 seconds, without requiring machine downtime intervention, directly improving the production line cycle time.

[0042] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] In the embodiments of this application, a feeding and positioning fixture for punching holes in a tapered bearing cage blank is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0047] like Figures 1 to 7 As shown, the present application provides a feeding and positioning fixture for punching holes in a tapered bearing cage blank. Specifically, regarding the structure of the tapered bearing cage blank 1, it is as follows: Figure 7As shown, it includes a bottom wall 11 and a tapered side wall 12. The tapered side wall 12 is used to punch pockets for limiting the rolling elements on the punching fixture. The bottom wall 11 is the leftover material punched in the final process of the cage forming process. The bottom wall 11 is provided with an eccentrically set positioning hole 111. The positioning hole 111 is used to cooperate with the positioning structure on the punching fixture. The positioning hole 111 provides an accurate position reference for the installation of the tapered bearing cage blank 1 in the punching fixture, so that the tapered bearing cage blank 1 can be installed on the punching fixture in the correct posture, ensuring the positional accuracy of subsequent punching. In terms of overall structure, the loading and positioning fixture includes a base, a rotating device 3 and an identification device 4. The base is provided with a loading platform 21 for accommodating the tapered bearing cage blank 1. The loading platform 21 is provided with a rotating station 211. The rotating device 3 can drive the tapered bearing cage blank 1 located at the rotating station 211 to rotate in order to adjust the position of the positioning hole 111. When the rotating device 3 adjusts the positioning hole 111 to the position identified by the identification device 4, it stops rotating the tapered bearing cage blank 1.

[0048] like Figure 3 The image shows the state of the loading and positioning fixture without the tapered bearing cage blank 1 in place, as shown. Figure 1 and Figure 2 The image shows the state in which multiple tapered bearing cage blanks 1 are placed in the loading and positioning fixture. At this time, the rotating device 3 drives one tapered bearing cage blank 1 located at the rotating station 211 to rotate until the positioning hole 111 is rotated to the position identified by the identification device 4.

[0049] In this technical solution, the linkage control of the rotating device 3 and the identification device 4 fundamentally solves the problem of low positioning efficiency caused by the random angle of the tapered bearing cage blank in automated conveying. Traditional conveyor belts can only achieve coarse positioning of the tapered bearing cage blank, while this application adds an active rotation adjustment function at the end of the conveyor, so that the tapered bearing cage blank 1 with any angle input can be dynamically corrected to the target angle at the rotating station 211. This allows the robot to take out the tapered bearing cage blank 1 with a fixed placement posture from the rotating station 211. It is only necessary to set the positioning structure in a certain position for the punching fixture to achieve rapid and accurate matching between the positioning hole 111 and the positioning structure, eliminating the time-consuming steps of adjusting the robot's posture or the tooling positioning structure. The real-time feedback of the identification device 4 reduces the single positioning time from tens of seconds in traditional automation solutions to less than 10 seconds or even 5 seconds, without the need for machine stoppage intervention, directly improving the production line cycle time.

[0050] As a preferred embodiment of this application, such as Figure 3As shown, the loading platform 21 is provided with a through hole 212 corresponding to the rotating station 211. The rotating device 3 can be raised and lowered to have a clearance position and a working position. When the rotating device 3 is in the clearance position, it is lower than the through hole 212. When the rotating device 3 is in the working position, it passes through the through hole 212 and can drive the tapered bearing cage blank 1 to rotate. Figures 1 to 4 The image shows the state of the rotating device 3 when it is in the working position. For example... Figure 5 The diagram shows the state of the rotating device 3 in the avoidance position. In this technical solution, the design of the adjustable rotating device 3 and the through hole 212 solves the problem of spatial interference between the rotating device 3 and the tapered bearing cage blank 1 during loading. In traditional solutions, a fixed rotating device would obstruct the sliding path of the tapered bearing cage blank on the conveyor platform, forcing the use of complex segmented conveying or robotic arm gripping and avoidance. This application, through a lifting and avoidance mechanism, allows the rotating device 3 to be completely hidden below the loading platform 21 during non-working periods. The conveyor belt can continuously and linearly transport the blank to the rotating station 211, eliminating the angle correction action in the robotic arm's gripping path and significantly increasing the loading speed.

[0051] In a preferred embodiment of this invention, the rotating device 3 includes a rotary motor 31 and a force transmission shaft 32 fixed to the rotary output shaft of the rotary motor 31. The rotary motor 31 drives the tapered bearing cage blank 1 to rotate via the force transmission shaft 32. Specifically, the rotary output shaft and the force transmission shaft 32 can be fixedly connected by means of key connection, coupling connection, or other suitable methods. In this technical solution, the direct drive structure of the rotary motor 31 and the force transmission shaft 32 overcomes the inertial offset defect when the robot grips and rotates. When a traditional robot grips and rotates a blank, the presence of gripper gap causes the rotation center to drift, resulting in secondary positioning errors.

[0052] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the force transmission shaft 32 includes a thin shaft section 321 and a thick shaft section 322 from top to bottom. A mating hole 112 for the thin shaft section 321 is provided in the center of the bottom wall 11. When the thin shaft section 321 mates with the mating hole 112, the thick shaft section 322 abuts against the bottom surface of the bottom wall 11. Figure 4 The diagram shows the state where the thin shaft section 321 is engaged with the mating hole 112. At this time, the thick shaft section 322 abuts against the bottom surface of the bottom wall 11. The stepped design of the thin shaft section 321 and the thick shaft section 322 achieves a dual function: the interference fit between the thin shaft section 321 and the mating hole 112 ensures no slippage in power transmission, while the surface contact between the end face of the thick shaft section 322 and the bottom surface of the blank forms an axial limit, preventing axial movement of the blank during rotation. Furthermore, the thick shaft section 322 can lift the tapered bearing cage blank 1 upwards a certain distance, reducing mutual interference between the tapered bearing cage blanks 1. Figure 2 and Figure 4 As shown, the force transmission shaft 32 lifts the tapered bearing cage blank 1 located at the rotating station 211 upwards by a certain distance before rotating it, making it higher than other tapered bearing cage blanks 1, thereby reducing mutual interference.

[0053] As a preferred embodiment of this implementation, such as Figure 1 As shown, a lifting cylinder 5 is installed on the base, which drives the rotating device 3 to lift and lower. In this technical solution, the linear drive of the lifting cylinder 5 has a faster response speed compared to the lead screw module, and achieves soft landing through air pressure buffering, avoiding micro-displacement of the blank caused by rigid impact. The lifting cylinder 5 has a built-in magnetic coupling position sensor that can monitor the lifting stroke in real time, forming a linkage control with the rotating device 3 to ensure that the rotation action is initiated only after the lifting position is reached, preventing mechanical interference.

[0054] Furthermore, such as Figure 1 and Figure 6 As shown, the cylinder body 51 of the lifting cylinder 5 is located below the loading platform 21, and the piston rod 52 of the lifting cylinder 5 is provided with a mounting plate 6. The rotating device 3 is fixedly installed on the mounting plate 6. In this technical solution, the layout of the lifting cylinder 5 can effectively hide the rotating device 3 below the loading platform 21 and drive the rotating device 3 to move, and also facilitates the assembly of the rotating device 3.

[0055] As a preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, the loading platform 21 is provided with a loading limiting slide 213 that accommodates and guides the tapered bearing cage blank 1 to move linearly. The first end 2131 of the loading limiting slide 213 is open to allow the tapered bearing cage blank 1 to enter. A rotating station 211 is located at the second end 2132 of the loading limiting slide 213. The second end 2132 is closed, stopping and limiting the tapered bearing cage blank 1 at the rotating station 211. Figure 2 As shown, under the constraint of the loading limit slide 213, multiple tapered bearing cage blanks 1 are arranged in a straight line and can move towards the rotating station 211 along a straight line. The loading limit slide 213 specifically solves the problem of disordered posture of the tapered bearing cage blanks 1 at the end of the conveyor belt, so that the tapered bearing cage blanks 1 move towards the rotating station 211 along a straight line, providing a pre-alignment reference for subsequent rotation positioning and significantly reducing rotation time. After the tapered bearing cage blanks 1 move to the second end 2132 of the loading limit slide 213, they are stopped by the closed inner wall of the loading limit slide 213, indicating that the tapered bearing cage blanks 1 have reached the rotating station 211, and the next step is to drive the rotating device 3 to move upward with the lifting cylinder 5.

[0056] As a preferred embodiment of this application, such as Figure 1 , Figure 3and Figure 4 As shown, the identification device 4 is installed on the base and located directly above the rotating station 211. In this technical solution, the vertical detection optical path is formed directly above the identification device 4. Compared with oblique detection, this can eliminate the perspective distortion caused by the tapered sidewall 12 of the tapered bearing cage blank 1, which greatly improves the edge recognition accuracy of the positioning hole 111 and effectively improves the accuracy of the identification device 4 in detecting the position of the positioning hole 111.

[0057] Furthermore, such as Figures 1 to 4 As shown, the base includes a vertical plate 22, a feeding platform 21 fixed to one side of the vertical plate 22, and a fixing plate 23 located above the feeding platform 21 on the vertical plate 22. The identification device 4 is installed on the fixing plate 23. The vertical plate 22, the feeding platform 21, and the fixing plate 23 form a frame structure, which is simple in structure and convenient for the installation of accessories.

[0058] In a preferred embodiment, the identification device 4 is a visual inspection device equipped with a camera. The deep learning algorithm of the visual inspection device can overcome the technical bottleneck of difficulty in identifying the positioning holes 111 in the reflective material blank, thereby improving the accuracy of the identification of the positioning hole 111's position. As an alternative embodiment, the identification device 4 can also be equipped with other suitable structures such as an optical measuring instrument or an intelligent inspection robot.

[0059] The material loading and positioning fixture in this application can adopt the following workflow:

[0060] (1) Feeding process

[0061] First, the tapered bearing cage blanks 1 can be placed one by one into the loading limit slide 213 through the opening of the first end 2131 of the loading limit slide 213 using a conveyor belt. The loading limit slide 213 serves to accommodate and guide the tapered bearing cage blanks 1, allowing them to move in a straight line. When the tapered bearing cage blanks 1 move to the second end 2132 of the loading limit slide 213, the second end 2132 is closed, and the tapered bearing cage blanks 1 are stopped and limited to the rotating position 211, at which point the conveyor belt stops moving.

[0062] (2) Lifting operation of rotating device 3

[0063] At this time, the lifting cylinder 5 located below the loading platform 21 begins to work. The piston rod 52 of the lifting cylinder 5 extends upward, driving the mounting plate 6 to rise. Since the rotating device 3 is fixedly installed on the mounting plate 6, the rotating device 3 rises accordingly. When the rotating device 3 rises to the working position, the force transmission shaft 32 passes through the through hole 212 on the loading platform 21 corresponding to the rotating station 211. The thin shaft section 321 of the force transmission shaft 32 mates with the mating hole 112 of the bottom wall 11 of the tapered bearing cage blank 1, and the thick shaft section 322 abuts against the bottom surface of the bottom wall 11.

[0064] (3) Position adjustment of positioning hole 111

[0065] The rotary motor 31 starts, driving the force transmission shaft 32 to rotate via the output shaft. The force transmission shaft 32 then drives the tapered bearing cage blank 1 to rotate. During the rotation of the tapered bearing cage blank 1, the identification device 4 (a vision inspection device with a camera) located directly above the rotary station 211 collects image information in real time to identify and monitor the position of the positioning hole 111. When the identification device 4 detects that the positioning hole 111 has reached the preset accurate position, it sends a signal to the control system. The control system then controls the rotary motor 31 to stop rotating, at which point the position adjustment of the positioning hole 111 is complete.

[0066] (4) Subsequent punching operations

[0067] After the positioning hole 111 is adjusted, the tapered bearing cage blank 1 can be transported to the punching fixture by the robot for punching operation; at the same time, the piston rod 52 of the lifting cylinder 5 retracts, driving the rotating device 3 to descend to the avoidance position, preparing for the loading and positioning of the next tapered bearing cage blank 1.
