Description

Technical Field

[0001] This utility model relates to the technical field of multi-station clamping turntables for wheel hubs, specifically a multi-station clamping turntable device for wheel hubs. Background Technology

[0002] The multi-station clamping turntable for wheel hubs is an important auxiliary device in the wheel hub processing process. It is mainly used to fix and rotate the wheel hub to a suitable position during processing to facilitate cutting, drilling, painting and other processing operations.

[0003] In practical applications, the existing multi-station clamping turntable devices for wheel hubs have relatively complete structures and functions, and can basically meet daily usage needs. However, the following problems still exist: In actual industrial production, although the adjustment capability of the clamping turntable mechanism of the multi-station clamping turntable device can adapt to different sizes of wheel hubs, in practice, the phenomenon of insufficient clamping or wheel hub displacement after clamping still occurs frequently. This leads to dimensional deviations, surface scratches, and even equipment failures caused by wheel hub loosening during processing, seriously affecting production efficiency and finished product qualification rate. The cause of the above problems is mostly that the wheel hub fails to achieve stable and accurate pre-positioning on the turntable placement station before being clamped by the clamping mechanism.

[0004] Therefore, this utility model provides a multi-station clamping turntable device for wheel hubs. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-station clamping turntable device for wheel hubs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station clamping turntable device for wheel hubs, including a clamping turntable mechanism, wherein a pre-placed support structure is provided on one side of the clamping turntable mechanism; The pre-placement support structure includes two L-shaped frames, each with an installation slot on one side of the opposite side. A first motor is installed on one of the L-shaped frames through the installation slot. A shaft is installed on the output end of the first motor. A square block is installed on one end of the shaft. Brackets can be detachably installed on both opposite sides of the square block. A movable structure is provided below the pre-placed support structure.

[0007] By adding a pre-placement support structure next to the clamping turntable mechanism, the wheel hub is initially positioned and stably placed on the pre-placement support structure before entering the clamping process, and then transferred to the clamping turntable mechanism for clamping. This avoids the instability that may occur when the wheel hub is placed directly on the clamping turntable mechanism, provides a stable foundation for the subsequent clamping process, and improves the reliability of clamping.

[0008] In a preferred embodiment, another L-shaped frame is rotatably connected to a rotating rod via a corresponding mounting slot, one end of which is connected to one side of the square block.

[0009] The technical effect of adopting the above-mentioned further solution is that the foundation is supported by two L-shaped frames, and the square block is connected by a rotating rod. The rotation of the rotating rod achieves the purpose of supporting the square block.

[0010] In a preferred embodiment, the L-shaped frame is fitted with a first bearing via the corresponding mounting slot, and the outer side of one end of the rotating rod is connected to the inner ring of the first bearing.

[0011] The technical effect of adopting the above-mentioned further solution is that the first bearing is used to support the rotating rod and assist the rotation of the rotating rod.

[0012] In a preferred embodiment, the movable structure includes two slide rails, each slide rail being slidably connected to a slider, and the two L-shaped frames being respectively connected to the corresponding sliders.

[0013] The technical effect of adopting the above-mentioned further solution is that the arrangement of two slide rails and two sliders is used to support the movement of the two L-shaped frames.

[0014] In one preferred embodiment, a second motor is mounted on one end of one of the slide rails, and a threaded rod is mounted on the output end of the second motor. The outer side of the threaded rod is threadedly connected to the inner wall of the corresponding slider.

[0015] The technical advantage of adopting the above-mentioned further solution is that by setting a second motor and a threaded rod, the slider can be moved.

[0016] In a preferred embodiment, a second bearing is mounted on the slide rail, and the outer side of the threaded rod is connected to the inner ring of the second bearing.

[0017] The technical effect of adopting the above-mentioned further solution is that by setting a second bearing, the threaded rod is supported and its rotation is assisted.

[0018] In a preferred embodiment, one end of the threaded rod has a threaded groove, and the threaded rod is threadedly connected to a threaded post through the threaded groove. One end of the threaded post is fitted with a limiting plate, and the outer side of the limiting plate has an anti-slip groove.

[0019] The technical effect of adopting the above-mentioned further solution is that by setting threaded grooves, threaded columns, limiting plates, and anti-slip grooves, the separation of the slider and the threaded rod can be avoided as much as possible.

[0020] This utility model provides a multi-station clamping turntable device for wheel hubs. It has the following beneficial effects: By setting up a pre-positioned support structure, the wheel hub is initially positioned on the bracket of the pre-positioned support structure before entering the clamping process. During this process, a bracket of appropriate diameter needs to be installed on the square block according to the size of the wheel hub, and then it is transferred to the clamping turntable mechanism for clamping. This avoids the problem of unstable placement that may occur when the wheel hub is placed directly on the clamping turntable mechanism, provides a stable foundation for the subsequent clamping process, and improves the reliability of clamping. By setting up a moving structure and starting the second motor, the bracket is moved to support the wheel hub during pre-support. After the clamping turntable mechanism clamps the wheel hub, the bracket is moved away from the wheel hub, thereby minimizing the obstruction of the bracket and its related parts from other machinery and workers' processing of the wheel hub.

[0023] 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.

[0024] like Figures 1-4 As shown, this embodiment provides a technical solution: a multi-station clamping turntable device for wheel hubs, including a clamping turntable mechanism 1. A pre-placement support structure 2 is provided on one side of the clamping turntable mechanism 1. The pre-placement support structure 2 includes two L-shaped frames 201. Each of the two L-shaped frames 201 has a mounting groove 202 on its opposite side. A first motor 205 is mounted on one of the L-shaped frames 201 through the mounting groove 202. A shaft 206 is mounted on the output end of the first motor 205. A square block 207 is mounted on one end of the shaft 206. Both opposite sides of the square block 207 can be detachably installed. With bracket 208, according to the above technical solution, specifically, by adding a pre-placed support structure 2 next to the clamping turntable mechanism 1, the wheel hub is initially positioned on the bracket 208 of the pre-placed support structure 2 before entering the clamping process. During this process, according to the size of the wheel hub, a bracket 208 of appropriate diameter needs to be installed on the square block 207, and then it is transferred to the clamping turntable mechanism 1 for clamping operation. This avoids the problem of unstable placement that may occur when the wheel hub is placed directly on the clamping turntable mechanism 1, provides a stable foundation for the subsequent clamping process, and improves the clamping reliability. The two brackets 208 pre-assembled on the square block 207 are compatible with the two wheel hub diameters required for this production. When the wheel hubs change alternately, the first motor 205 can be started to drive the rotation of the shaft 206. The rotation of the shaft 206 drives the rotation of the square block 207, thereby achieving the effect of adjusting the position of the two brackets 208.

[0025] Going further, such as Figure 2 As shown: Another L-shaped frame 201 is rotatably connected to a rotating rod 204 through a corresponding mounting slot 202. One end of the rotating rod 204 is connected to one side of the square block 207. According to the above technical solution, specifically, the basic support is achieved by using two L-shaped frames 201, and the rotating rod 204 is connected to the square block 207. The rotation of the rotating rod 204 achieves the purpose of supporting the square block 207.

[0026] The L-shaped frame 201 is fitted with a first bearing 203 via a corresponding mounting slot 202. One end of the rotating rod 204 is connected to the inner ring of the first bearing 203. The first bearing 203 reduces friction when the rotating rod 204 rotates, ensuring smooth rotation, enhancing the stability of the square block 207 and bracket 208 during rotation, reducing wear, extending the service life of the equipment, and ensuring the accuracy of angle adjustment.

[0027] The above solutions also have the problem that the structure of bracket 208 and its related parts can hinder other machinery and workers from processing the wheel hub, such as... Figures 1-3As shown: In this scheme: a movable structure 3 is provided below the pre-placed support structure 2. The movable structure 3 includes two slide rails 301, each slide rail 301 is slidably connected to a slider 302, and two L-shaped frames 201 are respectively connected to the corresponding sliders 302. A second motor 304 is installed at one end of one of the slide rails 301, and a threaded rod 303 is installed at the output end of the second motor 304. The outer side of the threaded rod 303 is threadedly connected to the inner wall of the corresponding slider 302. According to the above technical solution, specifically... By starting the second motor 304, the threaded rod 303 is rotated. The rotation of the threaded rod 303 causes the slider 302 to move. The movement of the slider 302 causes the L-shaped frame 201 to move. The movement of the L-shaped frame 201 causes the bracket 208 to move. Thus, the hub is supported during pre-support, and after the clamping turntable mechanism 1 clamps the hub, the bracket 208 is moved away from the hub, thereby minimizing the obstruction of the bracket 208 and its related parts from other machinery and workers' processing of the hub. Both slide rails 301 can be fixed to the ground by cement pouring.

[0028] Going further, such as Figure 3 As shown: A second bearing 305 is installed on the slide rail 301. The outer side of the threaded rod 303 is connected to the inner ring of the second bearing 305. The second bearing 305 supports the threaded rod 303, reduces friction and shaking when the threaded rod 303 rotates, improves the stability and smoothness of the rotation of the threaded rod 303, reduces the motor load, extends the service life of the equipment, and ensures the running accuracy of the moving structure 3.

[0029] Going further, such as Figure 4 As shown: One end of the threaded rod 303 has a threaded groove 306, and the threaded rod 303 is threadedly connected to a threaded post 308 through the threaded groove 306. One end of the threaded post 308 is equipped with a limiting plate 307, and the outer side of the limiting plate 307 has an anti-slip groove 309. By screwing the threaded post 308 into the threaded groove 306, the limiting plate 307 is assembled on the threaded rod 303, thus minimizing the risk of the slider 302 detaching from the threaded rod 303.

[0030] Working principle: like Figure 1-4 As shown: In use: By adding a pre-placed support structure 2 next to the clamping turntable mechanism 1, the wheel hub is initially positioned on the bracket 208 of the pre-placed support structure 2 before entering the clamping process. During this process, a bracket 208 of appropriate diameter needs to be installed on the square block 207 according to the size of the wheel hub, and then it is transferred to the clamping turntable mechanism 1 for clamping operation. This avoids the problem of unstable placement that may occur when the wheel hub is placed directly on the clamping turntable mechanism 1, provides a stable foundation for the subsequent clamping process, and improves the clamping reliability. By activating the second motor 304, the threaded rod 303 is rotated. The rotation of the threaded rod 303 causes the slider 302 to move. The movement of the slider 302 causes the L-shaped frame 201 to move. The movement of the L-shaped frame 201 causes the bracket 208 to move. This achieves support for the wheel hub during pre-support and moves the bracket 208 away from the wheel hub after the clamping turntable mechanism 1 clamps the wheel hub. This minimizes the obstruction of the bracket 208 and its related parts from other machinery and workers' processing of the wheel hub.
