Description

Technical Field

[0001] This utility model belongs to the field of bearing processing technology, specifically relating to a feeding device for bearing chamfering and polishing. Background Technology

[0002] The main purpose of chamfering and grinding bearing races is that if the edges of the races are sharp, they will scratch the rolling elements, cage or other parts; burrs will fall into the raceway and cause pitting and noise; and cracks are prone to occur at the sharp corners of the races. Chamfering can reduce assembly damage and improve service life.

[0003] Patent CN115609371A discloses an automatic bearing inner ring grinding device and its usage method, comprising a base body with a magnetic turntable mounted on the top center of the base body; a movable grinding mechanism is arranged on the left side of the top of the base body, and a storage mechanism is arranged on the upper side of the magnetic turntable; a transfer mechanism is arranged on the front side of the storage mechanism, and a discharge mechanism is arranged on the rear side of the storage mechanism; a transmission mechanism is arranged on the right side of the storage mechanism, and an automatic feeding mechanism is arranged on the rear side of the discharge mechanism. This invention provides a device that allows control of a first servo motor and a rotary motor via a control panel, thereby moving and rotating the grinding wheel. After grinding, a reciprocating rod moves, causing a limit stop to move the finished bearing inner ring body, thus enabling the device to automatically discharge the material after processing, eliminating the need for manual operation.

[0004] In the above scheme, the bearing inner ring is fed by the material storage mechanism on the upper side of the polishing position. However, each time the material can only be fed after all the polishing processes of the previous ring are completed. The lack of multi-station continuous feeding reduces the processing efficiency. Furthermore, under this structural layout, the end face of the bearing ring cannot be processed. Other equipment processes are required to make up for this, which increases the processing cost of the bearing. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing a feeding device for bearing chamfering and polishing that can solve the technical issues described above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for bearing chamfering and polishing includes a feeding platform, a feeding path is provided along the length of the feeding platform, a plurality of polishing modules are provided on the feeding platform and are sequentially passed through the feeding path, and a pushing component is provided on one side of the feeding platform and moves along the direction of the feeding path, and a plurality of extensions of the pushing component extend into the feeding path and move back and forth simultaneously between each of the polishing modules.

[0007] In the aforementioned feeding device for bearing chamfering and polishing, the pushing component includes a pushing baffle extending into the feeding path and a first pushing platform. The first pushing platform is slidably disposed on a pushing guide rail arranged along the direction of the feeding path, and the pushing baffle is driven to move along the direction of the feeding path by the first pushing platform.

[0008] In the aforementioned feeding device for bearing chamfering and polishing, a telescopic guide rail perpendicular to the feeding path is provided on the first pushing platform, and a second pushing platform connected to the pushing baffle is slidably disposed on the telescopic guide rail. The pushing baffle is driven by the second pushing platform to move vertically in and out of the feeding path.

[0009] In the aforementioned feeding device for bearing chamfering and polishing, each of the aforementioned push baffles is provided with a corresponding clamping baffle that moves relatively horizontally. The clamping baffles are slidably mounted on the clamping guide rail fixed to the second push platform.

[0010] In the aforementioned feeding device for bearing chamfering and polishing, the push baffle has a correction notch on the vertical surface on the same side as the operating direction of the feeding passage, and the correction notch has at least two symmetrical contact points with the bearing arc surface.

[0011] In the aforementioned feeding device for bearing chamfering and polishing, the polishing module includes two magnetic suction components and a flipping component. The feeding platform has a break between the two magnetic suction components, and the flipping component flips the bearing within the break.

[0012] In the aforementioned feeding device for bearing chamfering and polishing, the magnetic suction assembly includes a magnetic suction turntable and a magnetically conductive support coaxially disposed on the upper surface of the magnetic suction turntable. The magnetic suction turntable is disposed on the lower side of the feeding platform, and the magnetically conductive support extends into the through groove of the feeding platform and is flush with the surface of the feeding platform.

[0013] In the aforementioned feeding device for bearing chamfering and polishing, the flipping assembly includes two flipping clamps on the upper and lower sides, which are connected to the clamping robotic arm. The flipping clamp on the lower side is flush with the surface of the feeding platform.

[0014] In the bearing chamfering and polishing feeding device, a feeding pusher is provided at the beginning of the feeding direction of the feeding platform. The feeding pusher moves along the feeding path toward the polishing module. The pushing end of the feeding pusher is provided with a contour pushing notch.

[0015] In the aforementioned feeding device for bearing chamfering and polishing, a discharge slide is provided at the end of the feeding platform in the feeding direction. The discharge slide is inclined downward and connected to the storage channel. A pusher device that extends and retracts towards the storage channel is also provided at the lower end of the discharge slide.

[0016] The advantages of this utility model are: The pushing component is equipped with multiple pushing baffles that extend into the feeding path, enabling the bearing rings to be pushed into the next processing stage simultaneously. This allows the front end of the feeding platform to continuously feed the bearing rings in sync with the pushing rhythm of the pushing component, thereby increasing the turnover rate of bearing ring processing. Furthermore, the pushing component includes a correction notch and a clamping structure to ensure that the bearing rings remain on the feeding path during the pushing process, allowing them to accurately stop on the magnetic support.

Detailed Implementation

[0024] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings. However, the utility model is not limited to these embodiments.

[0025] like Figures 1-6 As shown, the feeding device for bearing chamfering and polishing includes a feeding platform 1, a feeding passage is provided along the length of the feeding platform 1, a plurality of polishing modules are provided on the feeding platform 1 and are sequentially passed through the feeding passage, and a pushing component 2 is provided on one side of the feeding platform 1 and moves along the feeding passage, and a plurality of extensions of the pushing component 2 extend into the feeding passage and move back and forth between each polishing module simultaneously.

[0026] That is, by using the feeding platform 1 as the slide of the bearing ring, the bearing rings at different positions are simultaneously transferred to the next position by multiple push baffles on the push assembly that extend to the feeding path, thereby increasing the feeding rate to improve the overall production capacity and ensuring the consistency of the polishing effect.

[0027] Among them, a straight groove of the same diameter as the ring can be opened on the feeding platform 1 and extended backward along the feeding path, so as to ensure the lateral position of the ring during travel in the absence of a positioning structure, so that the ring can accurately stop at the magnetic suction station.

[0028] In this embodiment, the pushing component 2 includes a pushing baffle 21 extending into the feeding path and a first pushing platform 22. The first pushing platform 22 is slidably disposed on a pushing guide rail 23 arranged along the feeding path. The pushing baffle 21 is driven to move along the feeding path by the first pushing platform 22.

[0029] The first pushing platform 22 serves as a large-area substrate carrying and pushing mechanism. The slider on its lower end surface slides in cooperation with the linear pushing track 23 fixed on the table, causing the pushing baffle 21 to move linearly along the feeding path. Placing the first pushing platform 22 on the side of the feeding platform 1 increases the arrangement space of the pushing track 23, allowing for more flexible selection of the movement range of the pushing component 2.

[0030] In this embodiment, a telescopic guide rail 24 perpendicular to the feeding path is provided on the first pushing platform 22, and a second pushing platform 25 connected to the pushing baffle 21 is slidably disposed on the telescopic guide rail 24. The pushing baffle 21 is driven to move vertically into and out of the feeding path through the second pushing platform 25.

[0031] Since the pusher baffle 21 needs to return to its original position after pushing the ring to the next station, in order to avoid touching the ring in place during the return process, the pusher baffle 21 is removed from the feeding path by the telescopic guide rail 24, thereby avoiding the ring in place.

[0032] Each push baffle 21 is uniformly mounted on a connecting rod, which is fixed to the second push platform 25 to achieve synchronous movement of each push baffle 21.

[0033] In this embodiment, each push baffle 21 is provided with a corresponding clamping baffle 26 that moves relatively horizontally, and the clamping baffle 26 is slidably disposed on the clamping guide rail 27 fixed on the second push platform 25.

[0034] To ensure the stability of the ring during movement, a clamping baffle 26 that can move independently and is parallel to the push baffle 21 is also installed on the second push platform 25. The clamping baffle 26 moves by relying on the clamping guide rail 27 to control the distance between the push baffle 21 and the clamping baffle 26, so as to achieve the purpose of clamping the ring for pushing.

[0035] The movement of the first pushing platform 22, the second pushing platform 25, and the clamping baffle 26 is all driven and controlled by motors.

[0036] In this embodiment, the push baffle 21 has a correction notch 28 on the vertical surface on the same side as the feeding passage operation direction, and the correction notch 28 has at least two symmetrical contact points with the bearing arc surface.

[0037] The two straight edges of the correction notch 28 form an angle greater than 90°. When the push baffle is pushed forward, the workpiece posture is automatically corrected through two-point contact, ensuring that the outer ring of the bearing always maintains the correct lateral position and improving the repeatability of the ring in the multi-stage polishing station.

[0038] In this embodiment, the polishing module includes two magnetic suction components 3 and a flipping component 4. The feeding platform 1 has a break between the two magnetic suction components 3, and the flipping component 4 flips the material in the break.

[0039] Polishing the chamfer of a bearing often requires processing both end faces. By using the space at the break, the two flipping clamps 41 can be used to switch the end faces of the bearing ring up and down, so that both end faces of the bearing ring can be polished in one process.

[0040] In this embodiment, the magnetic suction assembly 3 includes a magnetic suction turntable 31 and a magnetically conductive support 32 coaxially disposed on the upper surface of the magnetic suction turntable 31. The magnetic suction turntable 31 is disposed on the lower side of the feeding platform 1, and the magnetically conductive support 32 extends into the through groove of the feeding platform 1 and is flush with the surface of the feeding platform 1.

[0041] The iron magnetic support 32 is fixed to the magnetic turntable 31 with screws. Because the material channel is a general material channel, the protrusion hole of the magnetic support 32 for some small rings is too large. Therefore, a nylon annular filler block needs to be added to the small magnetic support 32 to prevent the material channel from being recessed, and to ensure that the magnetic support 32 and the annular filler block are flush with the platform surface so that the rings can enter and exit the magnetic suction station without obstruction.

[0042] The upper surface of the magnetic support 32 has some grooves to reduce the magnetic contact area and prevent the magnetic turntable 31 from being stuck on the magnetic support 32 after the magnetic function is turned off, thus preventing it from being moved away by the stepping robot.

[0043] In this embodiment, the flipping assembly 4 includes two flipping clamps 41 on the upper and lower sides. The two flipping clamps 41 are connected to the gripping rotating robotic arm 42, and the flipping clamp 41 on the lower side is flush with the surface of the feeding platform 1.

[0044] The lower flipping clamp 41 receives the collar in the fracture area, and the workpiece is clamped by closing the upper and lower clamps. Then, the upper and lower end faces of the collar are rotated 180° by the rotating joint of the clamping rotating robotic arm 42 to change the position of the collar.

[0045] Specifically, it is necessary to ensure that the flipping clamp 41 on the lower side is always aligned with the platform surface so that the ring can enter and exit without being obstructed. The gripping rotary robotic arm 42 includes a rotary drive fixed on the table and an opening and closing gripper mounted on the rotary drive. The flipping clamp 41 is fixed to the upper and lower jaws of the gripper respectively.

[0046] In this embodiment, a feeding pusher plate 11 is provided at the beginning of the feeding direction of the feeding platform 1. The feeding pusher plate 11 moves along the feeding path toward the polishing module. The pushing end of the feeding pusher plate 11 is provided with a contour pushing notch 12.

[0047] The feeding pusher plate 11 is responsible for pushing the rings on the rotating stacking frame into the feeding platform 1. It has an arc-shaped groove at the front end that is similar to the rings to perform preliminary posture correction on the rings. It also pushes the rings along the feeding path to the position where the pusher baffle 21 can receive them.

[0048] The rotating stacking rack consists of a distribution plate controlled by a motor and stacking stops on the distribution plate. During feeding, the lifting motor pushes the stacked rings to rise one ring at a time, so that the topmost ring can be moved from the rack to the feeding platform 1 under the push of the feeding push plate 11.

[0049] In this embodiment, a discharge slide 13 is provided at the end of the feeding direction of the feeding platform 1. The discharge slide 13 is inclined downward and connected to the storage channel 14. A pusher device 15 that extends and retracts towards the storage channel 14 is also provided at the lower end of the discharge slide 13.

[0050] The tail end of the feeding platform 1 is provided with an arc surface that connects with the unloading slide 13, so that the polished rings at both ends fall into the unloading slide 13 under the push of the push baffle 21, and roll down into the storage channel 14 with the inclined slope. Since the unloading slide 13 and the storage channel 14 are vertically connected due to space utilization issues, they are prone to material accumulation and blockage at the corner. Therefore, a pusher device 15 is provided at the corner to push the rings that fall to the corner towards the storage channel 14.

[0051] Among them, the pushing device 15 is a linear motor installed at the end of the feeding slide 13. The motor drives the push plate to push the ring into the storage channel 14.

[0052] In this embodiment, a rotating motor that can be raised and lowered is provided directly above the magnetic suction component 3. A polishing wheel is installed at the output end of the motor, and the polishing wheel is ensured to be coaxially aligned with the magnetic suction turntable 31.

[0053] The operation process of a single workpiece in this device: The ring is pushed from the material rack to the feeding platform 1 by the feeding push plate 11. After being pushed by the push component 2 after being reset, it is pushed to the first magnetic suction station for polishing one end face. Then it is pushed to the flipping station by the push component 2 for flipping. Then it is pushed to the second magnetic suction workpiece for polishing the other end face. After all polishing is completed, the push component 2 pushes the ring to the unloading slide 13 and finally gathers it in the storage channel 14.

[0054] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
