[0001] This utility model relates to the field of wheelchair hub technology, specifically a wheelchair hub deburring device. Background Technology

[0002] A wheelchair is a chair equipped with wheels that helps replace walking and is commonly used as a means of transportation for people with limb disabilities. The wheel hub is an important component of a wheelchair. Currently, burrs are inevitably generated during the manufacturing process of wheel hubs. The presence of burrs can affect the normal processing and use of the wheel hub, so a device is needed to remove the burrs from the wheel hub.

[0003] Currently used wheel hub deburring devices typically use a grinding wheel to polish the wheel hub to achieve the deburring effect. However, due to the irregular structure of the wheel hub, it is difficult to completely deburr the wheel hub using the above method. Therefore, we have proposed a wheelchair wheel hub deburring device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a wheelchair deburring device to solve the problem mentioned in the background art that the currently used wheelchair deburring devices cannot fully complete the deburring work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 The present invention provides a technical solution: a wheelchair hub deburring device, including a device base 1, a polishing sand box 2 on the device base 1, a brush rod 3 installed on the polishing sand box 2, and brush bristles 4 on the brush rod 3.

[0026] Furthermore, the brush rod 3 is threadedly connected to a pressing rod 17 at its end. The brush rod 3 is fixed in position on the polishing sand box 2 by the pressing rod 17, ensuring a stable connection between the brush bristles 4 on the brush rod 3 and the hub 18.

[0027] A hydraulic cylinder 5 is also installed on the base 1 of the device. A worktable 6 is fixed on the output end of the hydraulic cylinder 5. A motor 7 is installed on the worktable 6. An active rod 8 is fixed on the output end of the motor 7.

[0028] Furthermore, the outer surface of the drive rod 8 is evenly distributed with arc-shaped protrusions, and the hub 18 is located between the protrusions on the drive rod 8, which can stabilize the connection position of the hub 18 and thus enhance the stability of the hub 18 during the deburring process.

[0029] A movable seat 9 is fixed on the workbench 6. A servo electric cylinder 10 is installed above the movable seat 9. A movable block 11 is connected in the middle of the movable seat 9. The movable block 11 forms an up-and-down moving structure on the movable seat 9 through the servo electric cylinder 10.

[0030] A connecting rod 13 is movably mounted on the outer end of the movable block 11 via a rotating shaft 12. A driven rod 14 is movably mounted on the lower end of the connecting rod 13. The connecting rod 13 and the driven rod 14 follow the movable block 11 to form an up-and-down moving structure, which can facilitate the up-and-down positioning of the wheel hub 18.

[0031] Furthermore, a through-hole is provided on the connecting rod 13, and a connecting sleeve 15 is movably installed in the through-hole. A screw 16 is threadedly connected to the connecting sleeve 15. There are two connecting rods 13, and the threads of the connecting sleeves 15 on the two connecting rods 13 connected to the same screw 16 are opposite, which can control the opening and closing of the two connecting rods 13, so that the driven rod 14 can effectively position the wheel hubs 18 of different sizes.

[0032] Furthermore, both ends of the screw 16 are equipped with internal hexagonal socket heads for easy operation of the screw 16.

[0033] The outer side of the drive lever 8 is connected to the hub 18. The upper side of the hub 18 is connected to the limit via the driven lever 14. The hub 18 is embedded in the polishing sand box 2. The bristles 4 on the polishing sand box 2 are in contact with the hub 18.

[0034] Furthermore, a low-frequency vibration motor is provided at the bottom of the polishing sand box 2, and diamond sand is provided inside the polishing sand box 2, which enables the diamond sand inside the polishing sand box 2 to be in an active state, so as to facilitate the normal rotation of the wheel hub 18 embedded in the diamond sand, thereby ensuring the normal progress of the polishing work.

[0035] Specifically, when using this wheelchair hub deburring device, first pour diamond abrasive of appropriate mesh size into the polishing sand box 2, and then move the working position of the worktable 6 upward through the hydraulic cylinder 5 so that the hub 18 can be easily placed on the worktable 6.

[0036] When assembling the wheel hub 18, the moving block 11 is moved up by the servo electric cylinder 10, and the position of the connecting rod 13 and the driven rod 14 is moved up synchronously by the rotating shaft 12. Multiple wheel hubs 18 can be directly hung on the driving rod 8. Due to the setting of the protruding structure on the outside of the driving rod 8, the spacing between multiple wheel hubs 18 can be stabilized.

[0037] Then, based on the outer diameter of the hub 18, the spacing and reverse movement of the driven rods 14 on the connecting rod 13 are adjusted so that the driven rods 14 can stably limit the hub 18. When adjusting the driven rods 14, the screw 16 is rotated so that the connecting sleeve 15 moves relative to the screw 16, thereby enabling the two connecting rods 13 to open and close through the rotating shaft 12 to change the spacing between the driven rods 14.

[0038] After the working positions of the two driven rods 14 are determined, the moving block 11 is moved down by the servo electric cylinder 10, so that the positions of the two driven rods 14 are moved down, which can press down on the multiple wheel hubs 18 below, and fix the positions of the multiple wheel hubs 18 in conjunction with the driving rod 8.

[0039] After multiple wheel hubs 18 are installed, the worktable 6 is lowered by hydraulic cylinder 5 to move the position of the wheel hubs 18 downwards and move them into the polishing sand box 2. Before this, a sand groove is dug in the polishing sand box 2 to align with the wheel hubs 18. The lower side of the wheel hubs 18 is located in the sand groove after the groove is leveled. The lower side of the wheel hubs 18 can then be buried in the diamond sand.

[0040] Then, the motor 7 is started, causing the drive rod 8 to rotate. In conjunction with the driven rod 14, the hub 18 can be rotated. Meanwhile, the low-frequency vibration motor on the polishing sand box 2 is started, causing the diamond inside to be in an active state. This ensures that the diamond is in full contact with the hub 18 and that the hub 18 can rotate normally. When the hub 18 is rotating, it can be in contact with the diamond to perform grinding and polishing, thereby achieving the effect of removing burrs.

[0041] The above describes the working process of the device, and all content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0042] 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.
