Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a grinding device for forklift fork production and processing. Background Technology

[0002] During the production of forks, the forks need to be polished. In order to facilitate the "forking" action, the two arms of the fork are usually made into a gradually thinning shape. Therefore, the fork is not flat and has a sloping surface. Both the upper and lower end faces of the fork need to be polished to prevent the fork from damaging the goods during transportation.

[0003] Patent application CN202420536322.7 discloses a forklift fork polishing device, comprising multiple support columns and a polishing table fixedly mounted on the top of the support columns. The top of the polishing table has a groove, and a clamping and moving mechanism is arranged inside the groove. Two fixing blocks are fixedly mounted on the top of the polishing table, and a lower polishing roller is rotatably connected between the two fixing blocks. A second motor is fixedly mounted on the side wall of one of the fixing blocks, and the output end of the second motor is drivenly connected to the lower polishing roller. Lifting blocks are provided on the top of the two fixing blocks. In this invention, during the movement of the forks, the upper and lower polishing rollers are always pressed against the surface of the forks under the action of elastic components, avoiding insufficient polishing. There is no need to adjust the spacing between the polishing rollers, increasing the practicality and polishing efficiency of the device.

[0004] Existing technologies, through the elastic structure of the upper and lower grinding rollers, can achieve close contact and grinding with the upper and lower end faces of the forks, but still have shortcomings: First, existing fork polishing equipment lacks the ability to track and collect sparks generated during polishing, resulting in sparks flying everywhere at the fork polishing site, creating a poor overall processing environment and making it difficult for workers to continuously polish multiple forks. Secondly, the existing forks lack further fixation during processing, which causes the overall grinding accuracy to decrease due to vibration during grinding, thus affecting the overall fork production quality. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides a grinding device for forklift fork manufacturing. Through the arrangement of components such as the grinding frame, this invention enables the tracking, collection, and storage of sparks and debris generated during grinding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for forklift fork production and processing, comprising a workbench, a locking assembly for fixing forks is provided on the upper surface of one side of the workbench, a grinding frame is slidably provided on one side of the locking assembly on the upper surface of the workbench, a first grinding roller is rotatably provided inside the grinding frame, a second grinding roller is slidably provided below the first grinding roller inside the grinding frame, a vacuum cleaner is fixedly provided on one side of the grinding frame on the upper surface of the workbench, a folded pipe is detachably connected between the input port of the vacuum cleaner and one side port of the grinding frame, a filter baffle is detachably provided on one side of the first grinding roller inside the grinding frame, and a filter plate is rotatably provided on one side of the second grinding roller inside the grinding frame.

[0007] Optionally, both sides of the second grinding roller are provided with grooves on the side walls of the grinding frame, and a slider is slidably disposed inside each groove, and each slider is rotatably connected to one end of its adjacent second grinding roller.

[0008] Optionally, a first fixing plate is provided on the outer side wall of each slider, and a second fixing plate is provided below each first fixing plate on the outer side wall of the grinding frame.

[0009] Optionally, a sliding snap-fit ​​plate is slidably snapped onto the lower end face of the grinding frame below the filter plate, and one bottom end of the filter plate is rotatably connected to one end of the sliding snap-fit ​​plate. A plurality of first springs are connected between the sliding snap-fit ​​plate and the filter plate.

[0010] Optionally, a folded baffle is provided on one side of one or more of the first springs between the sliding snap plate and the filter plate.

[0011] Optionally, a rotating baffle is rotatably connected to the top of the filter plate, and a plurality of second springs are connected between the filter plate and the rotating baffle.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a grinding device for forklift fork production and processing includes a workbench 10. A locking assembly for fixing the forks is provided on the upper surface of one side of the workbench 10. The locking assembly includes a support frame 11 disposed on the upper surface of the workbench 10. A fixed frame 12 is slidably disposed inside the support frame 11. A groove is provided inside the support frame 11 to limit the vertical sliding of the fixed frame 12 within the support frame 11. A second push cylinder is provided on the upper surface of the support frame 11. The output end of the second push cylinder passes through the support frame 11 and is fixedly connected to the upper surface of the fixed frame 12. A shock-absorbing pad is provided at the connection between the output end of the second push cylinder and the upper surface of the fixed frame 12. A downward fixing plate 13 is slidably disposed inside the fixed frame 12. A third push cylinder is disposed above the downward fixing plate 13 on the upper surface of the fixed frame 12. The output end of the third push cylinder passes through the groove. The fixed frame 12 is fixedly connected to the upper end face of the lower pressure fixed plate 13. The two sides of the third push cylinder are provided with second guide rods on the upper end face of the lower pressure fixed plate 13. Each second guide rod is slidably connected to the fixed frame 12. When grinding the fork, the fork is first placed on the upper end face of the workbench 10. Then, one end of the fork is moved horizontally and engaged inside the fixed frame 12. Then, the third push cylinder is activated. The output end of the third push cylinder drives the lower pressure fixed plate 13 to move vertically downward, which cooperates with the fixed frame 12 to engage and fix the fork. Then, the second push cylinder is activated. The output end of the second push cylinder drives the fixed frame 12 and the fork and other components to move vertically until the upper grinding surface of the fork is tangent to the lower outer circle of the first grinding roller 16. This makes it easier for the first grinding roller 16 to grind the upper surface of the fork when it moves horizontally with the grinding frame 15 and other components.

[0020] Furthermore, such as Figure 3 and Figure 4As shown, a grinding frame 15 is slidably mounted on one side of the snap-fit ​​assembly on the upper surface of the worktable 10. A sliding frame 14 is slidably mounted on the outside of the grinding frame 15 on the upper surface of the worktable 10. The two ends of the sliding frame 14 are slidably connected to the two side walls of the worktable 10, and the sliding frame 14 is driven to slide horizontally above the worktable 10 by a lead screw and a motor. The upper surface of the grinding frame 15 is fixedly connected to the inner top surface of the sliding frame 14. A first grinding roller 16 is rotatably mounted inside the grinding frame 15. A first motor is fixedly mounted on one side of the first grinding roller 16 on the side wall of the grinding frame 15. The output end of the first motor passes through the grinding frame 15 and is fixedly connected to one side wall of the first grinding roller 16. The lower part of the first grinding roller 16 is located below the grinding frame 15. The grinding frame 15 has a second grinding roller 17 that slides inside. Both sides of the second grinding roller 17 are provided with grooves 18 on the side walls of the grinding frame 15. Each groove 18 has a slider 19 that slides inside. Each slider 19 is rotatably connected to one end of its adjacent second grinding roller 17. A second motor is fixedly installed on the outer wall of one of the sliders 19. The output end of the second motor passes through the slider 19 and is fixedly connected to one side wall of the second grinding roller 17. A first fixing plate 20 is provided on the outer wall of each slider 19. A second fixing plate 21 is provided below each first fixing plate 20 on the outer wall of the grinding frame 15. An elastic shock absorber 22 is connected between every two adjacent first fixing plates 20 and second fixing plates 21.

[0021] When grinding the upper and lower end faces of the fork, the lead screw is activated. The rotation of the lead screw causes the sliding frame 14 to move horizontally. The sliding frame 14 drives the grinding frame 15, the first grinding roller 16, and the second grinding roller 17 to move. Before the first grinding roller 16 and the second grinding roller 17 contact the upper and lower end faces of the fork, the first motor and the second motor are activated, respectively driving the first grinding roller 16 and the second grinding roller 17 to rotate, thereby grinding the upper and lower end faces of the fork. However, since the lower end face of the fork is usually inclined, as the second grinding roller 17 follows the sliding frame 14 and the grinding... During the horizontal movement of components such as frame 15, the distance between the second grinding roller 17 and the first grinding roller 16 increases. The second grinding roller 17 drives the sliders 19 on both sides to slide downwards in the sliding grooves 18 that are slidably connected to it. The elastic tension of the elastic damper 22 itself forms an elastic support between the second fixed plate 21 and the first fixed plate 20. This causes the second grinding roller 17, which is rotatably set between the two first fixed plates 20 and the two sliders 19 connected to it, to come into close contact with the lower end face of the fork, thereby forming a grinding process on the lower end face of the fork.

[0022] Furthermore, such as Figure 1 and Figure 3As shown, a vacuum cleaner 28 is fixedly installed on one side of the grinding frame 15 on the upper surface of the workbench 10. A folded pipe 27 is detachably connected between the input port of the vacuum cleaner 28 and one side port of the grinding frame 15. The vacuum cleaner 28 is a common vacuum cleaner, which is existing technology. The vacuum cleaner 28 can absorb and collect the sparks and debris generated by the grinding of the forks by the first grinding roller 16 and the second grinding roller 17 through the folded pipe 27 and the grinding frame 15. The folded pipe 27 can extend and retract in length as it moves horizontally with the grinding frame 15 and other components, thereby ensuring that the input end of the vacuum cleaner 28 can cooperate with the grinding frame 15 to form a real-time absorption and processing of the sparks and debris generated by the grinding of the forks.

[0023] It should be noted here that, with Figure 3 In the front view, the first motor drives the first grinding roller 16 to rotate counterclockwise, and the second motor drives the second grinding roller 17 to rotate clockwise. This ensures that when the first grinding roller 16 and the second grinding roller 17 grind the upper and lower surfaces of the fork, the sparks and debris generated are directed towards the inside of the grinding frame 15, making it easier to collect and store the sparks and debris generated during grinding.

[0024] Furthermore, such as Figure 3 and Figure 5 As shown, a filter baffle 29 is detachably installed on one side of the first grinding roller 16 inside the grinding frame 15. The filter baffle 29 is fixed to the inner top wall of the grinding frame 15 by bolts. The lower end face of the filter baffle 29 is tangent to the lower outer circular surface of the first grinding roller 16. This allows the lower end face of the filter baffle 29 to slide tightly against the upper end face of the fork when the filter baffle 29 moves horizontally with the grinding frame 15 and the first grinding roller 16, thereby increasing the sealing between the filter baffle 29 and the fork. The filter baffle 29 filters out sparks and debris generated during grinding, thus preventing large particles from being adsorbed into the vacuum cleaner 28 and causing blockages. At the same time, large sparks and debris contain a lot of heat and remain at a high temperature when they move into the vacuum cleaner 28, which may damage the vacuum cleaner 28. The filter baffle 29 effectively avoids the above problems. Moreover, the detachable design of the filter baffle 29 and the folded pipe 27 makes it easy to disassemble and clean the filter baffle 29 regularly.

[0025] Furthermore, such as Figure 3 and Figure 6As shown, a filter plate 31 is rotatably mounted on one side of the second grinding roller 17 inside the grinding frame 15. A sliding snap plate 30 is slidably snapped onto the lower end face of the grinding frame 15 below the filter plate 31. One bottom end of the filter plate 31 is rotatably connected to one end of the sliding snap plate 30. Multiple first springs 32 are connected between the sliding snap plate 30 and the filter plate 31. Damping pads are provided at both the upper and lower ends of the multiple first springs 32 to absorb the vibration generated when the first springs 32 are elastically tensioned and when the entire device is grinding. A rotating baffle 34 is rotatably connected to the top of the filter plate 31. Multiple second springs 35 are rotatably connected between the filter plate 31 and the rotating baffle 34. Damping pads are provided at the connection points between the multiple second springs 35 and the rotating baffle 34. The damping pads can absorb the vibration generated when the second springs 35 are elastically tensioned and when the entire device is grinding.

[0026] As the sliding contact plate 30, filter plate 31, and rotating baffle 34 move horizontally with the grinding frame 15 and grind the forks, the filter plate 31 forms an elastic support between the sliding contact plate 30 and the filter plate 31 under the elastic tension of multiple first springs 32. The rotating baffle 34 forms an elastic support under the elastic tension of multiple second springs 35, so that the upper end face of the rotating baffle 34 slides and abuts against the inclined lower end face of the fork. This allows the filter plate 31 to abut against the rotating baffle 34 and the sliding contact plate 30 at an incline, forming a filtering and collection effect of the vacuum cleaner 28 and the folded pipe 27 to absorb the sparks generated during grinding. With the setting of multiple first springs 32 and second springs 35, the rotating baffle 34 can follow the tilt change of the lower end face of the fork and slide and abut, ensuring the filtering effect of the filter plate 31 on the sparks and debris generated during the grinding of the lower end face of the fork.

[0027] It should be noted that when the forks are not being polished, the angle between the filter plate 31 and the sliding snap plate 30 will only increase slightly under the elastic tension of the multiple first springs 32. Under the elastic tension of the multiple second springs 35, the upper end of the rotating baffle 34 abuts against one side of the filter baffle 29. When the forks are being polished, one end of the forks will abut against the inclined upper end of the second scraper 38. As the polishing frame 15 and other components move horizontally, one end of the forks will press down on the second scraper 38 at an angle, causing the inclined upper end of the second scraper 38 to slide against the inclined lower end of the forks.

[0028] Furthermore, such as Figure 6 and Figure 7As shown, a folded baffle 33 is provided on one side of the plurality of first springs 32 between the sliding snap plate 30 and the filter plate 31. A baffle 36 is provided on one side of the rotational connection between the filter plate 31 and the rotating baffle 34 between the filter plate 31 and the rotating baffle 34. The folded baffle 33 and the baffle 36 respectively block the gap at the rotational connection between the sliding snap plate 30 and the filter plate 31, and the gap at the rotational connection between the filter plate 31 and the rotating baffle 34, thereby ensuring the filtration of the filter plate 31 for the adsorption and collection of spark debris.

[0029] Furthermore, such as Figure 5 and Figure 6 As shown, the side wall of the filter baffle 29 that abuts against the fork is provided with a first scraper 37, and the side wall of the rotating baffle 34 that is close to the second grinding roller 17 is provided with a second scraper 38. The arrangement of the first scraper 37 and the second scraper 38 can scrape off the upper and lower end surfaces of the fork after grinding, thereby further ensuring the cleanliness and smoothness of the upper and lower end surfaces of the fork after grinding. Example 2:

[0030] Based on Example 1, further examples are made, such as... Figure 1 As shown, two rotating locking grooves 23 are slidably arranged on one side of the first grinding roller 16 inside the grinding frame 15. Multiple rubber rollers 24 are rotatably arranged inside each rotating locking groove 23. All rubber rollers 24 are made of damping material. A first push cylinder 25 is provided on one side of the outer wall of the grinding frame 15. The output end of each first push cylinder 25 passes through the grinding frame 15 and is fixedly connected to one side wall of the rotating locking groove 23. The two sides of the output end of each first push cylinder 25 are pressed down. Each side wall of the fixed plate 13 is provided with a first guide rod 26, and each first guide rod 26 is slidably connected to the grinding frame 15. The output end of the first push cylinder 25 drives the rotating locking groove 23 and the multiple rubber rollers 24 rotatably arranged inside the rotating locking groove 23 to move horizontally, so that the multiple rubber rollers 24 abut against the side walls of the fork to be ground, forming a horizontal fixation for grinding the fork. Moreover, through the damping material characteristics of the rubber rollers 24 themselves, the vibration generated during grinding of the fork can be absorbed, further improving the precision and quality of grinding.

[0031] The first, second, and third push cylinders mentioned above are all electric push cylinders with a self-locking function, which is existing technology. The first and second motors are both asynchronous motors with good dustproof function, which is also existing technology. This solution will not elaborate further.

[0032] Finally, it should be noted that the grinding device for forklift fork production and processing in this utility model needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the various mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0033] Furthermore, in the grinding device for forklift fork production and processing in this utility model, the electric push cylinder, asynchronous motor, dust collector, etc. are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
