Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of automobile wheel hub production technology, specifically to a clamping and fixing device for automobile wheel hub production. Background Technology
[0002] As a core component of a vehicle's driving system, automotive wheel hubs directly affect a vehicle's safety, handling, and aesthetics. The production process of automotive wheel hubs typically involves machining or surface treatment steps such as turning, drilling, and painting, thus requiring clamping and fixing fixtures to secure the wheel hubs.
[0003] However, current traditional clamping and fixing devices in the industry mainly rely on mechanical claws, vacuum suction cups, or manual positioning, which are not only cumbersome to operate but also lack versatility. Traditional fixing fixtures are usually designed for specific wheel hub sizes and structures. To adapt to the production of different wheel hub models, especially when facing the significant differences in wheel hub sizes between cars and trucks, different fixtures need to be changed accordingly, resulting in high equipment costs and difficulty in meeting the needs of multi-variety wheel hub production. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.
[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
[0005] 1. The technical problem to be solved by the utility model:
[0006] This utility model provides a clamping and fixing device for automobile wheel hub production, which solves the technical problems existing in the background art.
[0007] 2. Technical Solution:
[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a clamping and fixing device for automobile wheel hub production, comprising a placement worktable, wherein a plurality of first radial grooves are correspondingly opened on the top of the placement worktable, the plurality of first radial grooves being evenly distributed in a ring, and a strip-shaped slider is correspondingly slidably installed in the first radial groove, wherein a clamping block for clamping and fixing the wheel hub is correspondingly installed on the top of the strip-shaped slider, and the radial position of the clamping block on the strip-shaped slider is adjustable; an adjustment mechanism is correspondingly provided in the placement worktable, the adjustment mechanism being driven to all the strip-shaped sliders on the placement worktable, and all the strip-shaped sliders are driven to move synchronously and radially through the adjustment mechanism.
[0009] Furthermore, the adjustment mechanism includes a gear disk, which is rotatably mounted in the center of the top of the workbench and is driven to rotate. The gear disk has a plurality of evenly distributed annular arc-shaped grooves. The bottom of the strip slider is provided with a limiting rod on the inner side. The number and position of the arc-shaped grooves correspond to the number and position of the limiting rods. The limiting rods are slidably engaged in the arc-shaped grooves of the gear disk. When the gear disk rotates, it can drive all the strip sliders to move synchronously in the radial direction.
[0010] Furthermore, a motor is installed at the bottom of the workbench, and a drive gear is installed on the output shaft at the top of the motor. The drive gear meshes with the gear disc.
[0011] Furthermore, a second radial groove is provided on the top of the strip slider, and the clamping block is slidably installed in the second radial groove of the strip slider and is limited and fixed by a wing bolt.
[0012] Furthermore, the second radial groove bottom of the strip slider is provided with multiple threaded holes at equal intervals, and the clamping block is provided with a vertical through mounting hole. The wing bolt passes through the mounting hole and is threaded into the corresponding threaded hole, thereby limiting and fixing the clamping block.
[0013] Furthermore, flexible blocks are installed on the clamping surfaces on both sides of the clamping block.
[0014] Furthermore, pressure sensors are installed on the clamping surfaces on both sides of the clamping block, and the flexible block is wrapped around the outside of the pressure sensors. The pressure sensors and the motor are electrically connected to the external control system.
[0015] Furthermore, the top of the placement workbench is provided with three first radial grooves, which are evenly distributed in a ring.
[0016] 3. Beneficial effects:
[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0018] This utility model is reasonably designed. By setting an adjustment mechanism, a motor drives a gear disk to rotate, which in turn drives multiple strip sliders to move synchronously and radially. This causes multiple clamping blocks to move synchronously and radially, thereby enabling the rapid clamping and loosening of automobile wheel hubs. It is very convenient to use and operate. Furthermore, the radial position of the clamping blocks on the strip sliders is adjustable, which can effectively adapt to the clamping and fixing needs of different models of wheel hubs with large size differences. There is no need to change different tooling equipment, so it has relatively good versatility, effectively reducing costs and meeting the production needs of various wheel hubs. Its overall structural design is simple and ingenious, easy to use, and highly practical.
[0019] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," "provided with," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example
[0030] See attached document Figures 1-4 This embodiment of a clamping and fixing device for automobile wheel hub production includes a placement worktable 1. The top of the placement worktable 1 has a plurality of first radial grooves 101, which are evenly distributed in a ring. A strip-shaped slider 2 is slidably mounted within each of the first radial grooves 101. A clamping block 3 for clamping and fixing the automobile wheel hub 10 is mounted on the top of each strip-shaped slider 2. The radial position of the clamping block 3 on the strip-shaped slider 2 is adjustable. An adjustment mechanism is provided within the placement worktable 1. The adjustment mechanism is drively connected to all the strip-shaped sliders 2 on the placement worktable 1, and drives all the strip-shaped sliders 2 to move synchronously and radially.
[0031] Specifically, the placement workbench 1 has a hollow cavity structure. The adjustment mechanism includes a gear disk 5, which is rotatably mounted in the middle of the top of the placement workbench 1 and is driven to rotate. The gear disk 5 has a plurality of evenly distributed annular arc grooves 501. The bottom of the strip slider 2 is provided with a limiting rod 8 on the inner side. The number and position of the arc grooves 501 correspond to the number and position of the limiting rods 8. The limiting rods 8 are slidably engaged in the arc grooves 501 of the gear disk 5. The rotation of the gear disk 5 can drive all the strip sliders 2 to move synchronously in the radial direction.
[0032] A motor 7 is installed at the bottom of the workbench 1. A drive gear 6 is installed on the output shaft at the top of the motor 7. The drive gear 6 meshes with the side gear ring of the gear disk 5. The motor 7 drives the drive gear 6 to rotate, thereby driving the gear disk 5 to rotate, thus clamping or releasing the car wheel hub 10.
[0033] To accommodate the clamping and fixing requirements of different wheel hub models 10 with significant size variations, a second radial groove 201 is correspondingly provided on the top of the strip slider 2. The clamping block 3 is slidably installed within the second radial groove 201 of the strip slider 2 and is fixed in place by a wing bolt 4. Specifically, multiple threaded holes 202 are equidistantly provided at the bottom of the second radial groove 201 on the strip slider 2. A vertically penetrating mounting hole 301 is correspondingly provided on the clamping block 3. The wing bolt 4 passes through the mounting hole 301 and is threaded into the corresponding threaded hole 202, thereby achieving the limiting and fixing of the clamping block 3. During operation, by adjusting the position of the clamping block 3 on the strip slider 2, the size of the wheel hub 10 that the device can clamp and fix can be adjusted to a considerable extent. Then, by using the motor 7 to drive the gear disk 5 to rotate slightly, the clamping or loosening of the wheel hub 10 can be achieved. When the clamping block 3 is located at the innermost side of the second radial groove 201, it can be used to clamp and fix a smaller wheel hub 10, and the clamping block 3 can abut against the inner ring of the wheel hub 10; when the clamping block 3 is located at the outermost side of the second radial groove 201, it can be used to clamp and fix a larger wheel hub 10, and the clamping block 3 can abut against the outer ring of the wheel hub 10.
[0034] Flexible blocks 9 are installed on the clamping surfaces on both sides of the clamping block 3. These flexible blocks 9 can be made of sponge or rubber, thus preventing scratches or indentations on the surface of the wheel hub 10 when clamping and fixing it, ensuring the appearance quality of the finished product. For easier adjustment, pressure sensors are installed on the clamping surfaces on both sides of the clamping block 3. The flexible blocks 9 are wrapped around the outside of the pressure sensors. The pressure sensors and the motor 7 are electrically connected to an external control system. The control circuit board can be located either outside the device or inside the placement table 1. When the pressure sensor detects pressure, the control system can stop the motor 7 from working, preventing excessive clamping force from affecting the quality of the wheel hub 10. Since the above circuit connection and control process are common in existing automated production technologies and belong to prior art, and its electrical control is not the core improvement point of this application, it will not be elaborated further here.
[0035] Theoretically, there should be no fewer than three first radial grooves 101 on the placement workbench 1. Specifically, in this embodiment, three first radial grooves 101 are provided on the top of the placement workbench 1, and the three first radial grooves 101 are evenly distributed in a ring.
[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
