Technical Field

[0001] This utility model relates to the field of wheel hub maintenance and surface treatment technology, specifically a rust removal device for wheel hubs. Background Technology

[0002] In the process of automobile repair and wheel refurbishment, the surface of wheel hubs is prone to rust due to oxidation and corrosion, which requires rust removal to restore their performance and appearance. Existing wheel hub rust removal methods mostly use manual grinding or ordinary sandblasting. Manual grinding is inefficient and easily damages the wheel hub base, while ordinary sandblasting devices have problems such as poor adaptability of clamping mechanisms, difficulty in stably fixing wheel hubs of different sizes, waste due to direct discharge of sand, dust diffusion and environmental pollution during rust removal, and uneven rust removal due to inconvenient adjustment of the sandblasting head position. Therefore, there is an urgent need for a special device that combines stable clamping, sand recovery, dust purification and efficient rust removal. Utility Model Content

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.

[0013] Please see Figure 1 - Figure 4 It includes a workbench 1, a clamping assembly, a rust removal assembly, a dust removal assembly, and a sand collection assembly; A mounting frame 2 is provided on the workbench 1. A mounting groove 201 is provided on the top of the inner wall of the mounting frame 2. A bidirectional lead screw 3 is provided in the mounting groove 201. One end of the bidirectional lead screw 3 is rotatably connected to the side wall of the mounting groove 201, and the other end is drivenly connected to the output end of the first motor 301 provided on the side wall of the mounting frame 2. Both ends of the bidirectional lead screw 3 are threadedly connected to connecting blocks 302. The bottom of the two connecting blocks 302 is fixedly connected to the top of the first connecting plate 4 and the second connecting plate 401, respectively. A clamping assembly is provided at the lower end of the first connecting plate 4 and the second connecting plate 401. The clamping assembly includes a first limiting post 5, a first limiting block 503, a limiting plate 6, a second limiting post 8, and a second limiting block 801. A first limiting post 5 is provided at the lower end of the first connecting plate 4. The first limiting post 5 is rotatably connected to the first connecting plate 4. The end of the first limiting post 5 away from the worktable 1 is connected to the output end of the second motor 501 provided on the side wall of the first connecting plate 4. A first limiting block 503 is fixedly connected to the outer periphery of the other end of the first limiting post 5. The other end of the first limiting post 5 is hollow, and multiple slots 502 are arranged in a ring array on the inner wall with the central axis as the center. Each slot 502 has a through hole 50 on the side away from the inner wall of the first limiting post 5. 21. A limiting plate 6 is provided in the slot 502. The two sides of the limiting plate 6 are engaged with the side of the slot 502 near the inner wall of the first limiting post 5. A fixing block 601 is provided in the middle of the side of the limiting plate 6 away from the inner wall of the first limiting post 5. The fixing block 601 is located in the through hole 5021 and the height of the fixing block 601 is higher than the through hole 5021. Multiple springs 7 are provided on both sides of the fixing block 601 on the limiting plate 6. One end of the spring 7 is fixedly connected to the side of the limiting plate 6 away from the inner wall of the first limiting post 5, and the other end is fixedly connected to the inner wall of the slot 502. A second limiting post 8 is provided on the side of the lower end of the second connecting plate 401 near the workbench 1. The second limiting post 8 is rotatably connected to the second connecting plate 401. A second limiting block 801 is fixedly connected to the outer periphery of the second limiting post 8. A rust removal component and a dust removal component are also provided on the workbench 1. A sand collection component is provided inside the workbench 1.

[0014] Through the above technical solution, a bidirectional lead screw 3 driven by a first motor 301 is set in the mounting frame 2. With the connecting blocks 302 threaded at both ends, it can drive the first connecting plate 4 and the second connecting plate 401 to move relative to each other, thereby adjusting the distance between the first limiting post 5 and the second limiting post 8. When the second limiting post 8 is inserted into the hollow structure of the first limiting post 5, it will squeeze the limiting plate 6 in the slot 502 on the inner wall of the first limiting post 5. This will cause the limiting plate 6 to compress the springs 7 on both sides and drive the fixing block 601 to extend out of the through hole 5021, forming a clamping force from the inside of the hole in the middle of the wheel hub. At the same time, the first limiting block 503 on the outer periphery of the first limiting post 5 and the second limiting block 801 on the outer periphery of the second limiting post 8 form a limit from both sides of the wheel hub. Combined with the second motor 501 driving the first limiting post 5 to rotate, the stable clamping and rotation function of wheel hubs of different sizes is realized, providing a reliable foundation for subsequent uniform rust removal.

[0015] This utility model provides a technical solution. The rust removal component includes a mounting plate 9, a slider 902, an electric telescopic rod 10, and a sand storage box 11. The mounting plate 9 is arranged opposite to the workbench 1 below the mounting frame 2. A groove 901 is provided on the side of the mounting plate 9 near the workbench 1. The electric telescopic rod 10 is arranged in the groove 901. The top output end of the electric telescopic rod 10 is fixedly connected to the bottom of the slider 902. The sand storage box 11 is arranged inside the workbench 1. Air pumps 1101 are arranged on both sides of the sand storage box 11. The top output end of the air pump 1101 is fixedly connected to one end of the hose 1102. The hose 1102 passes through the top of the workbench 1 and the middle of the slider 902 and is fixedly connected to the slider 902. A sandblasting head 1103 is provided at the other end of the hose 1102 on the side of the slider 902 near the workbench 1.

[0016] Through the above technical solution, mounting plates 9 are set up on the workbench 1 with opposite distribution. The electric telescopic rod 10 in the slide groove 901 can drive the slider 902 to move up and down, thereby adjusting the height of the sandblasting head 1103 on the slider 902. The sand storage box 11 inside the workbench 1 stores rust removal abrasive. The air pumps 1101 on both sides provide power and deliver the abrasive to the sandblasting head 1103 through the hose 1102 to achieve high-pressure sandblasting rust removal. With the help of the clamping assembly, the wheel hub is rotated, so that the sandblasting head 1103 set up oppositely can perform comprehensive and uniform rust removal operation on different height positions on both sides of the wheel hub, improving the rust removal efficiency and effect.

[0017] This utility model provides a technical solution. The dust removal component includes a dust removal device 12 and a baffle 903. Annular baffles 903 are provided on both sides of the mounting plate 9 on the workbench 1. Dust removal devices 12 are provided between the mounting plate 9 and the side wall of the mounting frame 2 on the workbench 1. Connecting pipes 1201 are provided at both ends on the side of the dust removal device 12 closest to the mounting plate 9. One end of the connecting pipe 1201 is fixedly connected to the dust removal device 12, and the other end passes through the baffle 903 and is fixedly connected to the baffle 903. A suction head 1202 is provided at the other end of the connecting pipe 1201 on the side of the baffle 903 away from the dust removal device 12.

[0018] Through the above technical solution, the annular baffles 903 set on both sides of the mounting plate 9 can physically block the sand and dust splashed during the rust removal process, preventing them from spreading to the outside of the device; the dust removal device 12 between the mounting plate 9 and the side wall of the mounting frame 2 is connected to the dust suction head 1202 inside the baffle 903 through the connecting pipe 1201, which can promptly remove and treat the dust in the area surrounded by the baffle 903, which not only avoids dust pollution of the working environment, but also reduces the adhesion and damage of dust to equipment parts. At the same time, in conjunction with the annular baffles 903, the sand can fall more easily into the sand collection component below, realizing the synergistic cooperation of dust removal and sand recovery.

[0019] This utility model provides a technical solution. The sand collection assembly includes a sand collection box 13. A conical sand inlet 101 is provided between the mounting plates 9 in the middle of the workbench 1. The sand collection box 13 is provided above the sand storage box 11 inside the workbench 1. Dovetail protrusions 1301 are provided on both sides of the top of the sand collection box 13. A dovetail groove 102 is provided at the lower top of the inner wall of the workbench 1, corresponding to the position of the dovetail protrusions 1301. The sand collection box 13 and the workbench 1 are detachably connected by the mortise and tenon joint between the dovetail protrusions 1301 and the dovetail groove 102.

[0020] Through the above technical solution, the conical sand inlet 101 between the mounting plates 9 in the middle of the workbench 1 can guide the sand falling after rust removal, so that the sand falls into the sand collection box 13 below, and avoids the sand from scattering to other areas inside the workbench 1; the dovetail protrusions 1301 on both sides of the top of the sand collection box 13 and the dovetail groove 102 on the top of the inner wall of the workbench 1 are detachably connected by mortise and tenon joint, which not only ensures the stability during sand collection, but also facilitates the quick disassembly of the sand collection box 13 for cleaning or recycling of sand.

[0021] This utility model provides a technical solution in which the side of the fixing block 601 away from the inner wall of the first limiting post 5 is set in an arc shape, and the side of the fixing block 601 away from the inner wall of the first limiting post 5 and the side opposite to the first limiting block 503 and the second limiting block 801 are both provided with a rubber anti-slip layer.

[0022] Through the above technical solution, the side of the fixing block 601 away from the inner wall of the first limiting post 5 is set as an arc shape, which can better fit the inner wall contour of the central hole of the wheel hub, avoid damage to the wheel hub caused by contact with sharp corners during clamping, and increase the contact area with the wheel hub to improve clamping stability. The rubber anti-slip layer set on this side of the fixing block 601 and the opposite side of the first limiting block 503 and the second limiting block 801 can not only prevent the wheel hub from slipping and shifting during the rotation and rust removal process by increasing friction, but also use the elasticity of rubber to buffer the clamping force, avoid rigid contact causing indentations or scratches on the surface of the wheel hub, and further ensure the reliability of clamping and the protection effect of the wheel hub.

[0023] The working principle of this utility model is as follows: The center hole of the wheel hub to be rusted is fitted onto the first limiting post 5. The first motor 301 is started to drive the double-acting screw 3 to rotate, so that the connecting blocks 302 at both ends drive the first connecting plate 4 and the second connecting plate 401 to move relative to each other until the second limiting post 8 is inserted into the hollow structure of the first limiting post 5. At this time, the second limiting post 8 presses the limiting plate 6 in the slot 502, forcing the limiting plate 6 to compress the spring 7 and drive the fixing block 601 to extend out from the through hole 5021, forming a clamping force from the inside of the center hole of the wheel hub. At the same time, the first limiting block 503 and the second limiting block 801 form a limit from both sides of the wheel hub, realizing the stable fixation of the wheel hub. Then, the second motor 501 is started to drive the first limit post 5, the second limit post 8 and the wheel hub to rotate synchronously. The electric telescopic rod 10 drives the slider 902 to move up and down along the slide groove 901 to adjust the height of the sandblasting head 1103. The air pumps 1101 on both sides of the sand storage box 11 work to transport the sand through the hose 1102 to the sandblasting head 1103 and spray it out to thoroughly remove rust from the rotating wheel hub. During the rust removal process, the annular baffle 903 prevents the sand and dust from spreading. The dust removal device 12 removes the dust in the area through the dust suction head 1202 connected by the connecting pipe 1201. The sand falls into the sand collection box 13 through the conical sand inlet 101. The sand collection box 13 is detachable through the mortise and tenon joint between the dovetail protrusion 1301 and the dovetail groove 102, which facilitates the recovery of sand and transfer to the sand storage box 11 for recycling, thus completing the entire process of wheel hub rust removal.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
