Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub angle double positioning device. Background Art

[0002] During the manufacturing process of automobile wheels, the surface of the wheel hub will be damaged, and there will be varying degrees of appearance defects during the transportation and production process of the wheel hub. During the rework process, the wheel hub will need to be polished and repaired to a certain extent. In order to ensure stable maintenance of the wheel hub, the wheel hub will be positioned to improve the repair effect.

[0003] At present, most of the ways to position the wheel hub use simple positioning methods, such as using a cylinder to control the pressure plate to press the wheel hub to achieve extrusion positioning of the wheel hub, and then repair the wheel hub. Although this method can position the wheel hub, it only squeezes and positions the wheel hub at one place. When the extrusion force is too large, it will cause the other end of the wheel hub to tilt upward. If the extrusion force becomes smaller, the wheel hub will move during the repair process, thereby offsetting the wheel hub repair position and affecting the repair effect of the wheel hub. Therefore, we propose a wheel hub angle double positioning device to solve the above problems. Utility Model Content

[0027] In a preferred embodiment, the upper surface of the disc 2 is fixedly connected to the rectangular column 4, the outer surface of the rectangular column 4 is provided with a groove 5, the inside of the groove 5 is fixedly connected to the first spring 6, one end of the first spring 6 is fixedly connected to the support rod 7, one end of the support rod 7 is fixedly connected to the support plate 8. When the device places the wheel hub on the disc 2, the wheel hub can be initially limited. The rectangular column 4 is installed on the disc 2, and the first spring 6 is installed inside the rectangular column 4. The support plate 8 will squeeze the inner wall of the wheel hub under the action of the first spring 6, so that the wheel hub can be stably installed on the upper surface of the disc 2.

[0028] In a preferred embodiment, heat dissipation holes 9 are provided on the outer surface of the processing table 1, and the heat dissipation holes 9 correspond to the positions of the electric telescopic rods 31. Two electric telescopic rods 31 are provided and are respectively arranged inside the processing table 1. The device drives the rectangular plate 311 to move downward by the electric telescopic rod 31, so as to drive the positioning hook 32 to position the wheel hub. The electric telescopic rod 31 is installed inside the processing table 1. The electric telescopic rod 31 will generate a certain amount of heat when working. If the heat is not dissipated in time, the electric telescopic rod 31 will be damaged. Therefore, heat dissipation holes 9 are provided on the outer surface of the processing table 1, which can dissipate the heat of the electric telescopic rod 31 in time and extend the service life of the electric telescopic rod 31.

[0029] In a preferred embodiment, one side of the moving block 331 is fixedly connected to the hollow cylinder 10, one end of the second spring 11 is fixedly installed inside the hollow cylinder 10, the other end of the second spring 11 is fixedly connected to the connecting rod 332, and the connecting rod 332 is slidably connected to the inside of the hollow cylinder 10. In order to improve the positioning effect of the wheel hub, the device will use an arc plate 33 to squeeze the outer surface of the wheel hub to limit it. In order to ensure the stable movement of the arc plate 33, a hollow cylinder 10 is installed on one side surface of the moving block 331, and a movable connecting rod 332 is installed inside the hollow cylinder 10. The connecting rod 332 is fixedly connected to the arc plate 33, so as to control the stable movement of the arc plate 33 and facilitate the limitation of the wheel hub.

[0030] The device positions the wheel hub by controlling the positioning hook 32. To facilitate positioning and disassembly, the positioning hook 32 is rotatably connected to the top of the moving block 331. Two moving blocks 331 are provided, and are respectively arranged on the left and right sides of the disc 2. A positioning hook 32 is rotatably installed on each moving block 331. When the positioning hook 32 is used to position the wheel hub, it is only necessary to rotate the positioning hook 32. When disassembling, it is also only necessary to rotate the positioning hook 32, so that the positioning hook 32 can be conveniently removed from the wheel hub.

[0031] Since the diameter of the wheel hub is not uniform, in actual processing, it is necessary to adjust the position of the positioning hook 32 for wheel hubs of different diameters, so a distance adjustment mechanism 12 is installed on the rectangular plate 311, and the distance adjustment mechanism 12 includes a sliding groove 121, a positioning screw 122 and a limit plate 123. The sliding groove 121 is opened on the upper surface of the rectangular plate 311, and the interior of the sliding groove 121 is slidably connected to the moving block 331. A plurality of threaded holes 13 are opened at the inner bottom of the sliding groove 121, and are evenly arranged at the inner bottom of the sliding groove 121. The outer surface of the moving block 331 is fixedly installed with the limit plate 123, and the internal thread of the limit plate 123 is connected to the positioning screw 122, and the positioning screw 122 is threadedly connected to the threaded hole 13.

[0032] When positioning the wheel hub, place the wheel hub on the disc 2, then move the moving block 331, adjust the distance between the moving block 331 and the wheel hub, so as to ensure that the positioning hook 32 can hook on the wheel hub. After determining the position of the moving block 331, screw the positioning screw 122 into the interior of the rectangular plate 311 to position the moving block 331, so that the positioning hook 32 can stably position the wheel hub for easy operation.

[0033] Specifically, the working process or working principle of a wheel hub angle double positioning device is as follows: the current way of positioning the wheel hub mostly uses a simple positioning method, such as using a cylinder to control a pressure plate to press the wheel hub to achieve extrusion positioning of the wheel hub, and then repair the wheel hub. Although this method can position the wheel hub, it only squeezes and positions the wheel hub at one place. When the extrusion force is too large, the other end of the wheel hub will be caused to warp upward, and when the extrusion force becomes smaller, the wheel hub will be driven to move during the repair process, thereby offsetting the wheel hub repair position, affecting the repair effect of the wheel hub, so this device is designed to solve this problem.

[0034] The device is used to position the wheel hub so as to repair it. In actual operation, the position of the moving block 331 is adjusted according to the diameter of the wheel hub to ensure that the positioning hook 32 can hook the wheel hub. The wheel hub is first placed on the upper surface of the disc 2, with the recessed portion on the wheel hub facing downward, and the wheel hub is covered on the outside of the rectangular column 4. At this time, the inner side of the wheel hub will be supported by the retractable support plate 8 on the rectangular column 4, so that it can be stably placed on the upper surface of the disc 2.

[0035] Then, by sliding the moving block 331 inside the sliding groove 121, the positioning hook 32 can be driven to move. After determining the position of the moving block 331, the positioning screw 122 can be rotated and screwed into the inside of the rectangular plate 311 to position the moving block 331, so that the positioning hook 32 can be used stably, and the positioning hook 32 is hooked into the recess on the wheel hub, and the rectangular plate 311 is driven to move downward by the electric telescopic rod 31, and the positioning hook 32 is pulled to move downward, so that the wheel hub can be stably hooked by the positioning hook 32, and the wheel hub can be stably placed on the disc 2, which is convenient for its repair.

[0036] The device installs a retractable connecting rod 332 on the moving block 331. When the moving block 331 is moved, the position of the arc plate 33 can also be moved. Under the action of the second spring 11, the arc plate 33 will be stably pressed against the outer surface of the wheel hub, thereby improving the positioning effect of the wheel hub and meeting the requirements of use.

[0037] It should be noted that the electric telescopic rod 31 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
