Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wheel hub technology, and more specifically, to a wheel hub processing fixing device that is easy to disassemble. Background Technology
[0002] In the automotive manufacturing and parts processing industry, wheel hubs are key components, and their machining accuracy and quality directly affect the overall performance and safety of a vehicle. Therefore, during wheel hub machining, stable and precise fixing is crucial to ensure machining accuracy, improve processing efficiency, and reduce scrap rates. Furthermore, the precise positioning, stable fixing, and convenient operation of the fixing device directly impact the machining accuracy, surface quality, and production efficiency of the wheel hub.
[0003] However, while existing wheel hub processing fixing devices can fix wheel hubs, they are mostly independent control structures that lack linkage and coordination design. Workers need to manually adjust the lifting components to the preset height and then operate the fixing components separately to fix the wheel hub. The operation process is cumbersome, which increases the intensity of manual labor, results in excessively long fixing preparation time, and thus seriously affects the overall processing efficiency.
[0004] In addition, existing fixing mechanisms mostly adopt rigid pressing methods without setting an effective elastic buffer and damping buffer synergy structure. The pressing force is difficult to adjust. If the pressing is too tight, it will easily cause scratches and deformation of the wheel hub surface. If the pressing is too loose, it cannot achieve a stable fixation. Moreover, the shape and structure of the pressing component are poorly adapted to the outer curvature of the wheel hub, making it difficult to fit tightly to the surface of wheel hubs of different specifications. As a result, the wheel hub is prone to sliding along the contact surface after fixing, affecting the processing accuracy and thus restricting the improvement of wheel hub processing quality and production efficiency.
[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in the related technologies, this utility model proposes a wheel hub processing fixing device that is easy to disassemble, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] Therefore, the specific technical solution adopted by this utility model is as follows:
[0008] A wheel hub processing fixing device that is easy to disassemble includes: a mounting frame; a drive mechanism disposed at the inner bottom and top of the mounting frame; a plurality of fixing mechanisms disposed around the mounting frame and cooperating with the drive mechanism; and a control panel mounted on the outer bottom of the mounting frame.
[0009] Furthermore, to enhance adaptability to different wheel hub sizes and ensure precise positioning during processing, the drive mechanism includes a hydraulic cylinder located at the bottom of the mounting frame. The output end of the hydraulic cylinder has a telescopic rod, the top of which is connected to a sleeve. A worktable is located on top of the sleeve, and a fixed shaft is mounted on top of the worktable. Several vertical plates are arranged around the outer circumference of the fixed shaft, and limit blocks are located on both sides of the worktable. Several support plates are connected between the bottom of the worktable and the outer circumference of the sleeve. These support plates have a triangular structure. Limiting grooves that mate with the limit blocks are formed on both sides of the interior of the mounting frame.
[0010] Furthermore, to improve the convenience of wheel hub fixing and disassembly and enhance the stability of the fixed state, the fixing mechanism includes fixing grooves around the mounting frame, a movable shaft inside the fixing grooves, a connecting plate sleeved on the outside of the movable shaft, and a pressure block in the middle of the side of the connecting plate near the worktable; a fixing plate on top of the connecting plate, and compression springs symmetrically arranged on one side of the fixing plate, with dampers inside the compression springs; the pressure plate is jointly mounted on the top of the two sets of dampers and compression springs, and several anti-slip protrusions are provided on one side of the pressure plate. A limiting plate that cooperates with the connecting plate is provided on the outside of the mounting frame. The fixing plate has a concave structure, and the top of the fixing plate has a semi-circular arc structure, which is the same as the outer arc of the wheel hub body. The bottom of the connecting plate has a semi-circular arc structure.
[0011] The beneficial effects of this utility model are as follows:
[0012] This invention, by setting up a driving mechanism and a fixing mechanism, solves the problems of poor compatibility with different specifications of wheel hubs and easy damage to the wheel hubs or processing deviations caused by insecure fixing during wheel hub processing through the coordinated cooperation of the driving mechanism and the fixing mechanism. This improves the adaptability to wheel hubs of different sizes and ensures accurate positioning during processing. At the same time, it avoids the problem of insufficient buffer protection during fixing, which affects the processing quality of the wheel hub. This improves the convenience of fixing and disassembling the wheel hub, enhances the stability of the fixed state, and ultimately improves the overall processing efficiency and quality.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0022] According to an embodiment of the present invention, a fastening device for wheel hub processing that is easy to disassemble is provided.
[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, a wheel hub processing fixing device that is easy to disassemble according to an embodiment of the present utility model includes: a mounting frame 1; a drive mechanism 2, which is disposed at the inner bottom and top of the mounting frame 1; a plurality of fixing mechanisms 3, which are disposed around the mounting frame 1 and cooperate with the drive mechanism 2; and a control panel 4, which is installed at the outer bottom of the mounting frame 1.
[0024] By employing the aforementioned technical solution of this utility model, a driving mechanism 2 and a fixing mechanism 3 are provided. Through the coordinated operation of the driving mechanism 2 and the fixing mechanism 3, the problems of poor compatibility with different specifications of wheel hubs, easy damage to the wheel hub, or processing deviations caused by insecure fixing are solved during wheel hub processing. This improves the adaptability to wheel hubs of different sizes and ensures accurate positioning during processing. At the same time, it avoids the problem of insufficient buffer protection during fixing, which affects the processing quality of the wheel hub. This improves the convenience of wheel hub fixing and disassembly, enhances the stability of the fixed state, and thus improves the overall processing efficiency and processing quality.
[0025] Furthermore, in practical applications, a control panel 4 is installed on the bottom outer side of the mounting frame 1. This control panel 4 is electrically connected to the drive mechanism 2. Operators can input relevant data through the human-machine interface of the control panel 4, thereby enabling the drive mechanism 2 and the fixing mechanism 3 to work together to fix the wheel hub body 5.
[0026] In one embodiment, the drive mechanism 2 includes a hydraulic cylinder 201 located at the bottom of the mounting frame 1. A telescopic rod 202 is located at the output end of the hydraulic cylinder 201. A sleeve 203 is connected to the top of the telescopic rod 202. A worktable 204 is located on the top of the sleeve 203. A fixed shaft 205 is located on the top of the worktable 204. Several vertical plates 206 are arranged around the outer circumference of the fixed shaft 205. Limiting blocks 207 are located on both sides of the worktable 204. Several support plates 208 are connected between the bottom of the worktable 204 and the outer circumference of the sleeve 203. The support plates 208 are triangular in structure. Limiting grooves 209 that mate with the limiting blocks 207 are provided on both sides of the interior of the mounting frame 1, thereby improving the adaptability to wheel hubs of different sizes and ensuring precise positioning during processing.
[0027] Working principle of drive mechanism 2: When the hub body 5 is placed on top of the workbench 204, the fixed shaft 205 on the top of the workbench 204 and several vertical plates 206 distributed on the outer circumference work together to assist in positioning the hub body 5, ensuring the accuracy of the hub body 5's placement. The limiting blocks 207 on both sides of the workbench 204 cooperate with the limiting grooves 209 on both sides inside the mounting frame 1 to restrict the lifting trajectory of the workbench 204 and prevent deviation during lifting. Several triangular support plates 208 are set between the bottom of the workbench 204 and the outer circumference of the sleeve 203. Utilizing the stable structural characteristics of triangles, they enhance the firmness of the connection between the workbench 204 and the sleeve 203 and the overall structural strength, ensuring that the workbench 204 remains stable during lifting and supporting the hub body 5. The operator controls the hydraulic cylinder 201 to start through the control panel 4. The hydraulic cylinder 201 converts hydraulic energy into mechanical energy, driving the telescopic rod 202 to perform linear telescopic movement. The telescopic rod 202 drives the top-connected sleeve 203 to rise and fall synchronously, enabling the worktable 204 on top of the sleeve 203 to rise and fall stably. When the worktable 204 moves the wheel hub body 5 downward to a suitable position, it triggers the fixing mechanism 3 to fix the wheel hub body 5 from all sides inward, ensuring that the wheel hub body 5 will not shake or shift during processing. After processing is completed, the operator controls the hydraulic cylinder 201 again through the control panel 4 to move the worktable 204 upward. At this time, the fixing mechanism 3 releases its fixation on the wheel hub body 5, and the operator can then remove the wheel hub body 5.
[0028] In one embodiment, the fixing mechanism 3 includes a fixing groove 301 arranged around the mounting frame 1. A movable shaft 302 is arranged inside the fixing groove 301. A connecting plate 303 is sleeved on the outside of the movable shaft 302. A holding block 304 is arranged in the middle of the side of the connecting plate 303 near the worktable 204. A fixing plate 305 is arranged on the top of the connecting plate 303. Compression springs 306 are symmetrically arranged on one side of the fixing plate 305. A damper 307 is arranged inside the compression spring 306. A holding plate 308 is arranged on the top of the two sets of dampers 307 and the compression springs 306. A plurality of anti-slip protrusions 309 are arranged on one side of the holding plate 308. A limiting plate 310 that cooperates with the connecting plate 303 is arranged on the outside of the mounting frame 1. The fixing plate 305 has a concave structure, and the top of the fixing plate 305 has a semi-circular arc structure, which is the same as the outer arc of the hub body 5. The bottom of the connecting plate 303 has a semi-circular arc structure, which improves the convenience of fixing and disassembling the wheel hub and enhances the stability of the fixed state.
[0029] Working principle of fixing mechanism 3: The fixing grooves 301 around the mounting frame 1 provide stable mounting support for the movable shaft 302. The movable shaft 302 serves as the rotation fulcrum of the connecting plate 303, enabling the connecting plate 303 to rotate. The semi-circular arc structure design at the bottom of the connecting plate 303 reduces frictional resistance during rotation. When the worktable 204 moves downward, the bottom side of the worktable 204 simultaneously presses against the pressing block 304 on the side of the connecting plate 303 near the center of the worktable 204. Under the pressure, the connecting plate 303 rotates around the movable shaft 302 towards the hub body 5, causing the concave fixing plate 305 at the top of the connecting plate 303 to move inward simultaneously. The top of the fixing plate 305 has a semi-circular arc structure with the same curvature as the outer side of the hub body 5, which can tightly fit the surface of the hub. The compression springs 306 symmetrically located on one side of the fixing plate 305 undergo elastic deformation when the pressing plate 308 is in contact with the hub body 5. Meanwhile, the internal damper 307 buffers pressure impacts, providing a continuous and stable holding force to the holding plate 308, ensuring that the holding plate 308 tightly presses against the wheel hub body 5. Several anti-slip protrusions 309 on one side of the holding plate 308 increase the friction between the contact surface and the wheel hub, preventing relative displacement of the wheel hub. The limiting plate 310 on the outer side of the mounting frame 1 limits the rotation range of the connecting plate 303, preventing excessive pressing. When the operator stops the hydraulic cylinder 201 via the control panel 4, the worktable 204 remains in a fixed position, thus achieving a stable fixation of the wheel hub body 5.
[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0031] In practical application, the operator places the wheel hub body 5 on top of the workbench 204 of the drive mechanism 2. The fixed shaft 205 and several vertical plates 206 on the workbench 204 assist in positioning the wheel hub body 5. The operator operates the control panel 4 to start the hydraulic cylinder 201, which converts hydraulic energy into mechanical energy, driving the telescopic rod 202 to retract. The telescopic rod 202 drives the top-connected sleeve 203 to move downwards synchronously, thereby linking the workbench 204 and the wheel hub body 5 on top of the sleeve 203 to descend smoothly (the working principle of the drive mechanism 2 is as described above). When the workbench 204 moves downwards, the bottom side of the workbench 204 exerts a holding force on the pressing block 304 of the fixing mechanism 3, causing the connecting plate 303 to rotate around the movable shaft 302 towards the wheel hub body 5. The connecting plate 303 drives the top fixing plate 305 to move inwards, and the fixing plate 305 fits the wheel hub surface through a semi-circular arc structure that matches the curvature of the wheel hub body 5. Simultaneously, the compression spring 306 on one side of the fixed plate 305 undergoes elastic deformation, and the internal damper 307 buffers the pressure impact, jointly providing a continuous and stable holding force for the holding plate 308, allowing the holding plate 308 to tightly press against the wheel hub body 5. The anti-slip ridges 309 on the surface of the holding plate 308 increase the friction of the contact surface to prevent wheel hub displacement, and the limiting plate 310 on the outer side of the mounting frame 1 limits the rotation range of the connecting plate 303. When the workbench 204 descends to the preset position, the operator controls the hydraulic cylinder 201 to stop running through the control panel 4, and the wheel hub body 5 on the workbench 204 remains fixed (the working principle of the fixing mechanism 3 is as described above).
[0032] After the wheel hub body 5 is processed, the staff controls the hydraulic cylinder 201 again through the control panel 4 to move the worktable 204 upward. At this time, the fixing mechanism 3 releases the fixing of the wheel hub body 5, and the staff takes out the wheel hub body 5.
