Technical Field

[0001] The utility model belongs to the technical field of automobile parts detection, and particularly relates to a detection device for automobile wheels. Background Art

[0002] A wheel hub is a cylindrical metal part used to support a tire with a shaft as the center inside the automobile tire. It is the part where the wheel center installs the axle. Before leaving the factory, the automobile wheel hub needs to be detected for aperture, air tightness, roundness, etc.

[0003] For example, Chinese utility model CN217786008U discloses a detection fixture for automobile wheel hubs. Through the mutual cooperation between a placement table, a rotating shaft, a transmission mechanism, an arc plate, etc., it can realize that turning a worm drives a worm wheel and a circular plate to rotate, so that a fixing plate expands outwards to fix the wheel hub. In this way, wheel hubs of different sizes can be fixed, effectively solving the problem of low application range.

[0004] However, during the detection process, it is necessary to push a U-shaped plate to drive the detector body to rotate around the wheel hub, making the measurement operation inconvenient, and it is not easy for the detection personnel to observe the readings, resulting in poor overall detection convenience.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0026] Please refer to Figure 1 and 2 As shown in, the present invention is a detection device for automobile wheels, including a frame platform 1 and a turntable 2 rotatably connected above the frame platform 1, and there is a gap between the turntable 2 and the frame platform 1. The frame platform 1 is supported and fixed by brackets or legs, and the brackets or legs are not shown in the figure.

[0027] As Figure 3 and 4As shown in the figure, the frame platform 1 is connected with a lifting assembly, and through the lifting assembly, a lifting plate 3 is connected. On the upper surface of the lifting plate 3, an annular guide rail 301 concentric with the turntable 2 is fixedly connected, and through the annular guide rail 301, three sliders 302 are connected.

[0028] Among them, the turntable 2 is fixedly connected with a rotating column 205, and through the rotating column 205, it is rotatably connected with the frame platform 1, so that there is a certain distance between the turntable 2 and the frame platform 1.

[0029] The lifting assembly includes three screw sleeves 101 rotatably connected with the frame platform 1, and a slewing ring is rotatably connected. The slewing ring can be installed through a circular track and a track slider to achieve a rotational connection with the frame platform 1.

[0030] The slewing ring is fixedly connected with an internal gear ring 102, and is drivingly connected with a driving assembly for driving the slewing ring to rotate through the driving assembly. For example, the driving assembly includes a worm gear ring 103 fixedly connected with the slewing ring and a worm 104 rotatably connected with the frame platform 1 and meshing with the worm gear ring 103. One end of the shaft of the worm 104 is connected with a crank 106 for manually rotating the worm 104 through the crank 106, and for driving the slewing ring to rotate through the meshing transmission between the worm 104 and the worm gear ring 103.

[0031] The three screw sleeves 101 are circumferentially evenly distributed along the rotation center of the turntable 2. On the outer wall of the screw sleeve 101, a gear 105 meshing with the internal gear ring 102 is fixedly connected. Thus, through the rotation of the slewing ring, by the meshing transmission between the internal gear ring 102 and the gear 105, the three screw sleeves 101 are synchronously driven to rotate.

[0032] Moreover, the lifting plate 3 is fixedly connected with a screw 303 threadedly matched with the screw sleeve 101 for driving the screw sleeve 101 to rotate through the internal gear ring 102, so that the screw 303 generates an axial movement, and thus drives the lifting plate 3 to move up and down by means of the screw 303.

[0033] As Figure 5 shown in the figure, the turntable 2 is provided with three chutes 201 along the radial direction, and a sliding block 202 is slidably connected in the chute 201. On the upper surface of the sliding block 202, a fixed block 203 is fixedly connected. The lower end of the sliding block 202 is hinged with a connecting rod 204. The connecting rod 204 penetrates through the chute 201, and the lower end is hinged with the slider 302, so that the three sliding blocks 202 are connected to the slider 302 one by one through the connecting rod 204.

[0034] The frame platform 1 is connected with a detector body 4 through a mounting bracket. The mounting bracket can use the structure in the prior art to install and fix the detector body 4, such as using a magnetic base, etc.

[0035] Push the lifting plate 3 upward through the lifting component, and use the connecting rod 204 to push the sliding block 202 to move outward from the center of the turntable 2, so that it abuts against the inner wall of the wheel hub through the fixing block 203, and the wheel hub is fixed by internal expansion. During detection, rotate the turntable 2, so that the turntable 2 drives the wheel hub to rotate. At this time, the connecting rod 204 can rotate with the turntable 2 through the slider 302, so that it not only meets the clamping operation of the wheel hub, but also can rotate the wheel hub through the turntable 2.

[0036] When the turntable 2 drives the wheel hub to rotate, use the detector body 4 to detect the wheel hub, so that both the operator and the detector body 4 can complete the detection of the wheel hub without moving their positions, making it easier for the detection personnel to observe the readings during the detection process, thus effectively improving the overall detection convenience.
