Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, and more specifically to an automobile wheel hub clamp. Background Art

[0002] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel, and tire bell. There are many types of wheel hubs according to diameter, width, molding method, and material. In order to facilitate processing, the wheel hub generally needs to be fixed by a special clamp during processing so that the wheel hub can be accurately processed. However, the current automobile wheel hub clamps are all fixed and clamped on the outside of the wheel hub, resulting in a part of the outer edge of the wheel hub being blocked by the clamp, and some wheel hubs need to be processed on the outside, resulting in the staff needing to loosen the wheel hub clamp, rotate the wheel hub a certain angle, and then re-fix and clamp it before continuing to process the wheel hub. This method increases the processing time of the wheel hub and the labor intensity of the staff, reduces the processing efficiency of the wheel hub, and is not convenient for the staff to use. Utility Model Content

[0003] In order to overcome the above defects of the prior art, the utility model provides an automobile wheel hub clamp to solve the problems existing in the above background technology.

[0004] The utility model provides the following technical solution: an automobile wheel hub clamp comprises a workbench, an inner drive motor is arranged at the bottom of the workbench, an outer drive motor is arranged at the bottom of the workbench and is located on one side of the inner drive motor, an outer turntable is arranged at the top of the workbench, an outer fixing groove is opened on the surface of the outer turntable, a clamping plate is arranged inside the outer fixing groove, a movable column is arranged at the top of the clamping plate, a fixing plate is arranged at the top of the movable column, a movable plate is arranged at one side of the fixing plate, an inner turntable located on the inner side of the outer turntable is arranged at the top of the workbench, an inner fixing assembly is arranged on the top of the inner turntable, and the inner drive motor controls the inner turntable to move the inner turntable. The inner turntable is kept stationary, and the outer turntable is controlled to rotate slowly by an external driving motor, so that the outer turntable rotates with the fixed plate on its top, so that the moving plate squeezes the steel ring inside the hub body, so that when the moving plate is driven to rotate by the outer turntable, the fixed plate itself will also rotate on the clamping plate, and drive the moving plate to rotate, so that the contact surface of the moving plate and the steel ring fits, thereby increasing the contact area between the moving plate and the steel ring. In the process of continuous rotation of the outer turntable, since the inner fixed component remains stationary, the moving plate will continue to squeeze the steel ring, so that the moving plate and the inner fixed component are used in combination to fix the hub body from the inside thereof;

[0005] Furthermore, the number of the external fixing grooves is at least twelve, and the twelve external fixing grooves are distributed around the top of the outer turntable. Through the multiple external fixing grooves, it is convenient for the staff to install the clamping plate in the external fixing groove according to the shape and size of the hub body, thereby increasing the application scope of the device and the comfort of the staff.

[0006] Furthermore, a spring column is provided inside the fixed plate, and a movable plate is provided at one end of the spring column. The movable plate can continuously squeeze the hub body through the spring column, so that the pressure sensor can record the pressure of the movable plate fixing the hub body, thereby facilitating the staff to fix the hub body according to the reading size.

[0007] Furthermore, a pressure sensor is provided at the other end of the spring column, and the pressure sensor can record the elastic force indication of the spring column in real time, so that when the moving plate fixes the wheel hub body, the pressure when fixing the wheel hub body can be recorded, thereby preventing the pressure from being too high or too low, thereby preventing the wheel hub body from being unable to be clamped or fixed or causing damage to the wheel hub body.

[0008] Furthermore, fixing bolts are provided on both sides of the clamping plate, and the clamping plate is fixed in the outer fixing groove by the two fixing bolts, so that the fixing plate can squeeze and fix the wheel hub body.

[0009] Compared with the prior art, the present invention has the beneficial effect of controlling the inner turntable to remain stationary by the inner driving motor, and controlling the outer turntable to rotate slowly by the outer driving motor, and then the outer turntable rotates with the fixed plate on its top, so that the movable plate squeezes the steel ring inside the wheel hub body, so that in the process of the movable plate being driven to rotate by the outer turntable, the fixed plate itself will also rotate on the clamping plate, and drive the movable plate to rotate, so that the contact surface of the movable plate and the steel ring fits together, thereby increasing the contact area between the movable plate and the steel ring, and in the process of continuous rotation of the outer turntable, since the inner fixing component remains stationary, the movable plate will continue to squeeze the steel ring, so that the movable plate and the inner fixing component are used in combination to fix the wheel hub body from its inner side, which is convenient for the staff to process the outer side of the wheel hub body, thereby increasing the comfort of the staff.

[0018] Embodiment 1

[0019] Reference Figure 1-5 , a car wheel hub clamp, first install the movable column 8 on the top of the card plate 7, then install the pressure sensor 10 at one end of the spring column 11, and then install four groups of pressure sensors 10 equidistantly inside the fixed plate 9, then install the limit plate 13 on the outside of the movable plate 12, then install the movable plate 12 inside the fixed plate 9, and connect the other end of the spring column 11 to the movable plate 12, then install the inner drive motor 2 and the outer drive motor 3 on the inner side of the workbench 1 respectively, then open an outer fixed groove 6 around the surface of the outer turntable 5, then install the outer turntable 5 on the top of the workbench 1, and then install the inner turntable 14 on the inner side of the outer turntable 5 on the top of the workbench 1, then install the card plate 7 inside the outer fixed groove 6, and fix it with the fixing bolts 16, and finally install the inner fixing assembly 15 around the top of the inner turntable 14.

[0020] The working principle of the utility model is as follows: the staff installs the inner fixing assembly 15 above the inner turntable 14 according to the shape of the wheel hub body 4, and installs the clamping plate 7 inside the outer fixing groove 6, so that the fixing plate 9 and the inner fixing assembly 15 are inserted into the inside of the wheel hub body 4. At this time, the staff controls the inner turntable 14 to remain stationary through the inner driving motor 2, and controls the outer turntable 5 to rotate slowly through the outer driving motor 3, so that the outer turntable 5 rotates with the fixing plate 9 on its top, so that the moving plate 12 squeezes the steel ring inside the wheel hub body 4, so that the moving plate 12 is driven to rotate by the outer turntable 5. The fixing plate 9 itself will also rotate on the clamping plate 7, and drive the moving plate 12 to rotate, so that the contact surface of the moving plate 12 and the steel ring fits, thereby increasing the contact area between the moving plate 12 and the steel ring. Since the inner fixing assembly 15 remains stationary, the movable plate 12 will continue to squeeze the steel ring, and then the steel ring squeezes the movable plate 12 and the spring column 11 at one end thereof, and the pressure sensor 10 will record the pressure at this time. At the same time, the pressure recorded by the pressure sensor 10 will be sent to the control device, so that it is convenient for the staff to observe the pressure for fixing the hub body 4, preventing the pressure from being too small, resulting in the hub being not firmly fixed, and excessive pressure from causing damage to the steel ring inside the hub, thereby increasing the safety of hub fixation; and the multiple external fixing grooves 6 opened on the top of the outer turntable 5 allow the staff to install the card plate 7 and the inner fixing assembly 15 at different positions according to the different shapes of the hub body 4, so that it can fix the hub body 4, thereby increasing the applicability of the device and the comfort of the staff.
