Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub processing, and particularly relates to a clamping device for automobile wheel hub processing. Background Technique

[0002] In the process of automobile production and processing, various components need to be produced, processed and assembled. As an essential component for the automobile to achieve walking, the clamping of the automobile wheel hub plays an important role. The wheel hub is the part where the axle is installed in the center of the wheel. In the production, processing and assembly of the automobile wheel hub clamping, it is crucial to control the quality of each step.

[0003] Currently, a fixture is required in the process of wheel hub processing. The joint of the automobile wheel hub in the prior art is as Figure 4 shown in Figure 4 where A is the wheel hub mounting edge, B is the wheel hub body, C is the wheel hub shaft hole, and D is the tire mounting groove. The commonly used automobile wheel hub clamping tool includes a fixture for positioning the wheel hub on the machine tool. Although this clamping method is relatively firm, it is troublesome to operate.

[0004] The utility model patent with the patent authorization announcement number CN214642998U discloses an automobile wheel hub clamping tooling, which includes a table board. The upper surface of the table board is rotatably connected with a gear turntable. The upper surface of the gear turntable is fixedly connected with a placement bottom plate. The upper surface of the placement bottom plate is fixedly connected with a rotating support column. One end of the rotating support column is rotatably connected with a rotating turntable. The upper surface of the placement bottom plate is circumferentially fixedly connected with a fixture support column around the rotating support column. One end of the fixture support column is fixedly connected with a fixture bottom plate. One side of the fixture bottom plate is provided with a tensioning screw rod. The upper surface of the fixture bottom plate is provided with a fixture lock head. The lower surface of the table board is fixedly connected with support legs. Rollers are arranged below the support legs. One side of the support legs is fixedly connected with a motor. One side of the support legs is provided with a lighting lamp.

[0005] The overall structure of the above device is relatively large and occupies a large space. It can only clamp one wheel hub. During the clamping process, since the side surface of the wheel hub is inclined, the fit degree between its clamping lock head and the wheel hub is not high. The wheel hub is prone to swing during the processing, and at the same time, the clamping lock head is also prone to wear and damage.

[0006] Therefore, it is very necessary to invent a clamping device for automobile wheel hub processing to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a clamping device for automobile wheel hub processing, by setting a jacking mechanism and an elastic hub pressing member, so as to solve the problems of large space occupation of the clamping device and easy damage of the clamping head mentioned in the above background technique.

Detailed Embodiments

[0025] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "over", "upper", and "side (e.g., as in "side wall")" to describe the relationship between one component and another (other) component as shown in the accompanying drawings. In addition to the orientation depicted in the accompanying drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the accompanying drawings is flipped, the component described as "under" or "beneath" another component or feature will then be positioned "above" the said other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0026] As Figures 1 - 3As shown in the figure, a clamping device for machining automotive wheels in the present disclosure includes a machining platform. There are multiple working areas 1 for placing wheels on the machining platform to achieve the clamping function of multiple wheels. A positioning shaft 3 is fixedly installed at the middle position of the upper surface of the working area 1. The positioning shaft 3 is used to support the central shaft hole position of the wheel roller to achieve rapid positioning. To stably support the wheel, a plurality of support rods 4 in the circumferential direction of the positioning shaft 3 are fixedly installed on the upper surface of the working area 1. The support rods 4 can support the bottom position of the tire mounting edge of the wheel. At the same time, to clamp the tire mounting groove, a plurality of pushing mechanisms 2 are fixedly installed on the upper surface of the working area 1. The plurality of pushing mechanisms 2 are located outside the support rods 4. The upper end of the pushing mechanism 2 is movably hinged with a turning plate 5. One end of the bottom of the turning plate 5 is detachably installed with an elastic hub pressing member 8. The elastic hub pressing member 8 is used to elastically contact the tire mounting groove to achieve the function of fixing the wheel.

[0027] In this embodiment, a support block 6 is fixedly installed on one side of the pushing mechanism 2 close to the support rod 4. A pull rod 7 is movably hinged on the support block 6. The upper end of the pull rod 7 is movably hinged with the middle part of the turning plate 5.

[0028] In this embodiment, the elastic hub pressing member 8 includes a steel sleeve 81, a threaded joint 83 and a screw rod 84. The upper part of the steel sleeve 81 is open. The lower part of the threaded joint 83 is movably hinged inside the steel sleeve 81 through a pin shaft 85. The upper end of the screw rod 84 is fixedly installed at one end of the bottom of the turning plate 5. The lower end of the screw rod 84 is in threaded fit with the threaded joint 83. A rubber layer 82 is fixedly provided on the outside of the steel sleeve 81.

[0029] In this embodiment, further, to ensure that the rubber layer 82 outside the steel sleeve 81 can stably fit with the tire mounting groove of the wheel, torsion springs are installed at both ends of the pin shaft 85. Under the action of elastic torsion force, the rubber layer 82 of the steel sleeve 81 fits smoothly with the tire mounting groove.

[0030] Further, to adjust the machining height of the wheel, in this embodiment, the support rod 4 includes a threaded sleeve 41 and a threaded column 42. The threaded sleeve 41 is fixedly installed on the working area 1. The threaded column 42 is in threaded fit with the threaded sleeve 41. By rotating the threaded column 42, the overall height of the support rod 4 can be adjusted, thereby raising or lowering the height of the wheel.

[0031] Further, to improve the stability of clamping the tire mounting groove, in this embodiment, a support rod 4 is provided directly below the elastic hub pressing member 8.

[0032] In this embodiment, the pushing mechanism 2 is a cylinder or a hydraulic cylinder.

[0033] The specific operation steps are as follows: Place the automobile wheel hub to be processed on the working area 1, insert the positioning shaft 3 into the shaft hole of the wheel hub, and by adjusting the height of the support rod member 4, the support rod member 4 can stably support at the bottom position of the wheel hub mounting edge, ensuring that the wheel hub can be processed at an appropriate height;

[0034] Control the flip plate 5 to flip towards the tire mounting groove through the pushing mechanism 2, and the elastic hub pressing member 8 can fit with the tire mounting groove. Since the tire mounting groove is inclined, the steel sleeve 81 of the elastic hub pressing member 8 can gradually incline during the fitting process until it completely fits with the tire mounting groove, realizing the fixation of the wheel hub.
