Description

Technical Field

[0001] This invention specifically relates to a grinding device for processing rubber bushings. Background Technology

[0002] A rubber bushing is a connecting component, mainly composed of a rubber layer and a metal sleeve. It is used to absorb vibration and shock, protect equipment or vehicle parts from wear and damage, and improve operational smoothness and comfort. The end face quality of the rubber bushing directly affects assembly accuracy and performance. After the rubber bushing is molded, both ends typically require edge grinding to remove burrs, ensure flatness of the end face, and maintain dimensional accuracy.

[0003] Currently, the edge grinding of rubber bushings is mostly done manually or with semi-automated equipment. During processing, workers need to manually pick up the rubber bushings one by one and place them in the grinding station, and then use a grinding wheel to trim the end face of the bushing.

[0004] Since rubber bushings often require simultaneous processing at both ends, existing equipment mostly only allows for single-end grinding. After completing one end, repositioning is necessary before grinding the other end, which is not only cumbersome but also prone to positioning errors. Furthermore, during batch processing, workers must continuously perform repetitive operations such as loading, shifting, straightening, and unloading, resulting in high labor intensity and fatigue over long periods, thus affecting processing accuracy and product yield. Therefore, a grinding device for rubber bushing processing is proposed to solve the above problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a rubber bushing edge grinding device to address the problem that existing rubber bushings mostly require workers to manually pick up the rubber bushings and move them to the grinding station before grinding both ends separately. This increases the labor intensity of workers and reduces work efficiency when performing batch edge grinding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for processing rubber bushings, comprising: A frame, on which a receiving frame is provided; A lifting frame is intermittently raised and lowered on the frame via a drive mechanism.

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Please see Figure 2 , 46. The present invention provides a grinding device for processing rubber bushings, including a frame 1, a receiving frame 2 on the frame 1, a lifting frame 12 that can be intermittently raised and lowered on the frame 1 via a drive mechanism, a mounting frame 15 on the lifting frame 12, a receiving seat 16 on the mounting frame 15, a drive mechanism including a drive disk 30 rotatably mounted on the frame 1, a drive shaft 31 eccentrically mounted on the drive disk 30, a drive frame 23 on the lifting frame 12, the drive shaft 31 slidably locked in the drive frame 23, a ratchet 33 on the drive disk 30, a pawl 34 mounted by a spring on the frame 1, the pawl 34 locked in the ratchet 33, and a power component connected to the drive disk 30 on the frame 1, the power component driving the drive disk 30 to rotate intermittently by 180°.

[0024] The power assembly includes a drive wheel 35 rotatably mounted on a frame 1, a drive motor 38 mounted on the frame 1 to drive the drive wheel 35 to rotate, two sets of first arc-shaped racks 36 spaced apart around the drive wheel 35, a first gear 32 mounted on a drive disk 30, the first gear 32 meshing with the first arc-shaped racks 36, and the number of teeth of the first arc-shaped racks 36 being half the number of teeth of the first gear 32.

[0025] The drive motor 38 can be controlled to start and drive the drive wheel 35 to rotate. During the rotation of the drive wheel 35, it drives the drive disc 30 to rotate through one of the first arc-shaped racks 36. During the rotation of the drive disc 30, the drive shaft 31 and the drive frame 23 work together to drive the lifting frame 12 to rise and fall intermittently. One rotation of the drive disc 30 controls the lifting frame 12 to rise and fall once. The rotation of the drive disc 30 is unidirectionally locked by the cooperation of the pawl 34 and the ratchet 33 to prevent the lifting frame 12 from falling due to its own weight after the first arc-shaped rack 36 disengages from the first gear 32. A slot can be opened on the drive frame 23 to engage with the drive shaft 31 to prevent the drive disc 30 from continuing to rotate due to inertia after the lifting frame 12 has rotated to the highest position, thereby controlling the lifting frame 12 to rise and fall stably and intermittently. During the rising and falling of the lifting frame 12, the receiving seat 16 can also rise and fall.

[0026] Please see Figure 2 , 6In this embodiment, a conveying mechanism is provided on the frame 1. The conveying mechanism intermittently conveys the rubber bushing to the top of the receiving seat 16. The conveying mechanism includes two sets of conveying rollers 3 arranged at intervals. The conveying rollers 3 are rotatably mounted on the frame 1. A transmission component connected to one of the sets of conveying rollers 3 is provided on the drive wheel 35. The transmission component drives the conveying rollers 3 to rotate intermittently. The rotation time of the conveying rollers 3 does not coincide with the rotation time of the drive disc 30. Two sets of conveyor belts 5 are spaced on the two sets of conveying rollers 3. Multiple sets of receiving brackets 6 are provided on the conveyor belts 5. A feeding frame 7 is provided on the frame 1. The bottom opening of the feeding frame 7 is located on one of the sets of receiving brackets 6. An opening 8 is provided on the bottom of the feeding frame 7 facing the direction of movement of the conveyor belt 5.

[0027] The transmission assembly includes a first synchronous pulley 4 disposed on one of the sets of conveying rollers 3, a second arc-shaped rack 37 disposed on the drive wheel 35, the second arc-shaped rack 37 facing the gap between the two sets of first arc-shaped racks 36, a second gear 39 rotatably disposed on the frame 1, the second gear 39 can mesh with the second arc-shaped rack 37, a second synchronous pulley 40 disposed on the second gear 39, and the second synchronous pulley 40 is connected to the first synchronous pulley 4 by a synchronous belt 41.

[0028] When the drive wheel 35 rotates, when the first arc-shaped rack 36 meshes with the first gear 32, the rubber bushings located on two sets of receiving brackets 6 can be lifted by the rising receiving seat 16. After one set of first arc-shaped racks 36 disengages from the first gear 32, the lifting frame 12 does not move, allowing the rubber bushings on the receiving seat 16 to be polished. After polishing, the other set of first arc-shaped racks 36 meshes with the first gear 32, controlling the receiving seat 16 to descend, and the rubber bushings move back onto the receiving bracket 6. Subsequently, the first arc-shaped rack 36 disengages from the first gear 32, and the second... The arc-shaped rack 37 meshes with the second gear 39 to drive the second synchronous pulley 40 to rotate. During the rotation of the second synchronous pulley 40, it can drive one of the conveyor rollers 3 to rotate through the cooperation of the synchronous belt 41 and the first synchronous pulley 4, so as to control the movement of the conveyor belt 5 to move the unpolished rubber bushing to the receiving seat 16 for the next polishing. The feeding frame 7 can continuously feed multiple sets of receiving brackets 6. After the rubber bushing at the bottom of the feeding frame 7 is removed from the opening 8, the rubber bushing inside the feeding frame 7 moves down and falls onto two new sets of receiving brackets 6, thereby realizing the automatic conveying of the rubber bushing.

[0029] Please see Figure 1 , 34, 5. In this embodiment, the mounting frame 15 is provided with a clamping mechanism connected to the lifting frame 12. When the mounting frame 15 rises, the clamping mechanism drives the clamping mechanism to close and clamp the rubber bushing located on the receiving seat 16. The clamping mechanism includes two sets of clamps 18 arranged at intervals and slidably disposed at both ends of the mounting frame 15. The bottom of the clamps 18 is provided with a first drive column 19. At least two sets of inclined frames 9 are provided on the frame 1. The bottom end of the inclined frame 9 is connected to a first straight frame 10, and the top end is connected to a second straight frame 11. The first drive column 19 is slidably locked in the first straight frame 10.

[0030] In the initial state, the first drive column 19 is located at the bottom of the first straight frame 10. When the lifting frame 12 rises, it drives the first drive column 19 to slide within the first straight frame 10. After the receiving seat 16 lifts the rubber bushing on the receiving bracket 6, the first drive column 19 slides within the inclined frame 9, thereby controlling the two sets of grippers 18 to close and clamp and fix the rubber bushing, preventing the rubber bushing from shifting during subsequent grinding and improving the grinding effect.

[0031] Please see Figure 4 , 5 7. In this embodiment, the frame 1 has two opposing edge grinding mechanisms on both sides. The edge grinding mechanisms are connected to the lifting frame 12 via a linkage component, so that the lifting of the lifting frame 12 is converted into driving the edge grinding mechanism to slide and contact the end face of the rubber bushing. The receiving seat 16 is fixedly connected to the mounting frame 15. The bottom of the receiving seat 16 is provided with a mounting rod 14, which is slidably inserted on the lifting frame 12. A first elastic member 17 is provided between the receiving seat 16 and the lifting frame 12.

[0032] The edge grinding mechanism includes a mounting bracket 20 that can slide laterally on the frame 1. A connecting bracket 24 is slidably mounted on one side of the mounting bracket 20. An edge grinding motor 27 is mounted on the connecting bracket 24. An edge grinding wheel 28 is provided at the output end of the edge grinding motor 27. Two sets of concentrically arranged abrasive rings 29 are provided on the inner side of the edge grinding wheel 28. A second elastic element 25 is provided between the mounting bracket 20 and the connecting bracket 24. A control switch 26 is provided on one side of the connecting bracket 24. The control switch 26 is spaced apart from the mounting bracket 20 and is electrically connected to the edge grinding motor 27. The linkage component includes second drive columns 13 provided at both ends of the lifting frame 12. A straight groove 21 is provided on the mounting bracket 20. The top of the straight groove 21 is connected to an inclined groove 22. The second drive columns 13 are slidably engaged in the straight groove 21.

[0033] In the initial state, the second drive column 13 is located inside the straight groove 21. During the upward movement of the lifting frame 12, the second drive column 13 slides within the straight groove 21, pushing the mounting frame 15 and the receiving seat 16 upward through the first elastic element 17. When the clamping mechanism clamps and fixes the rubber bushing, the first drive column 19 is located at the top of the second straight frame 11. The lifting frame 12 continues to slide, compressing the first elastic element 17, and the second drive column 13 slides within the inclined groove 22, thereby controlling the two sets of mounting brackets 20 to slide and close until the two sets of frosted rings 29 respectively contact the rubber bushing. The outer and inner edges of the bushing abut each other. The mounting bracket 20 continuously slides to compress the second elastic element 25 and triggers the control switch 26, thereby controlling the two sets of edge grinding motors 27 to start and drive the edge grinding wheels 28 to rotate to automatically edge the rubber bushing. After edge grinding is completed, the lifting frame 12 descends, and the two sets of edge grinding wheels 28 slide laterally to disengage from the rubber bushing. The receiving seat 16 descends so that the edge-ground rubber bushing moves back to the receiving bracket 6. The conveyor belt 5 transports the rubber bushing until it falls into the receiving frame 2 for collection.

[0034] Specific usage and beneficial effects of the present invention: During operation, this device automatically and intermittently conveys rubber bushings to the receiving seat 16 via a conveying mechanism, eliminating the need for manual loading and repositioning, thus reducing human intervention. A drive mechanism controls the intermittent lifting of the lifting frame 12 and mounting frame 15 on the frame 1. The clamping mechanism automatically closes and clamps the rubber bushings as the mounting frame 15 rises, achieving rapid and automatic centering and fixing, ensuring stable and accurate edge grinding. Two sets of edge grinding mechanisms are linked to the lifting frame 12 via a linkage component, converting the lifting motion of the lifting frame 12 into lateral sliding feed. This allows both edge grinding mechanisms to simultaneously contact the two end faces of the rubber bushing, achieving synchronous edge grinding at both ends and avoiding repetitive positioning errors and time losses caused by single-end processing. The overall structure of this device features stable and reliable multi-action coordination, enabling continuous automated edge grinding of batches of rubber bushings, effectively reducing the labor intensity of workers and improving work efficiency.
