[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a car wheel cover welding fixture, including a fixture table 1, two groups of straight grooves 2 are opened through the top of the fixture table 1, and a transmission component is provided between the outer bottom end and the inner bottom end of the fixture table 1, and the side end of the transmission component is provided with a clamping component for clamping the wheel hub, and the top end of the clamping component is provided with a pressing component for pressing the wheel cover, and the clamping component can be driven by the transmission component to clamp and fix the wheel hub, and the wheel cover can be pressed and fixed by the pressing component, so as to facilitate personnel to perform welding operations on the wheel cover and the wheel hub, so that personnel do not need to manually fix the position of the vehicle wheel hub and the vehicle wheel cover, thereby avoiding easy damage to the user during the electric welding process, and will not cause errors between the wheel hub and the wheel cover, thereby avoiding affecting the quality of the final wheel.

[0021] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the transmission assembly includes a motor 4, which is fixedly mounted on the outer bottom end of the clamp table 1. A rotating rod 5 is mounted on the output end of the motor 4. The rotating rod 5 extends through the interior of the clamp table 1. The outer end of the rotating rod 5 is fixedly connected to a gear 6. By starting the motor 4, the rotating rod 5 and the gear 6 can be driven to rotate clockwise or counterclockwise, thereby facilitating the clamping assembly to clamp or release.

[0022] As an implementation method in this embodiment, Figure 2 、 Figure 3 and Figure 4The top of rack 7 and rack 2 8 are respectively meshed with each other on both sides of gear 6, and the top of rack 1 7 and rack 2 8 are fixedly connected with sleeve 9, and the side end of each sleeve 9 is fixedly connected with connecting rod 10, and the side end of each connecting rod 10 is fixedly connected with inserting sleeve 11, and each sleeve 9 passes through straight groove 2 and is located at the outer top end of clamping platform 1, and each inserting sleeve 11 is located at the outer top end of clamping platform 1, and two groups of T-shaped slide grooves 3 are opened at the top of clamping platform 1, and the bottom end of each inserting sleeve 11 is fixedly connected with T-shaped slider 12, and each slider 12 is slidably connected in each slide groove 3. Since each slider 12 and each slide groove 3 are T-shaped, rack 1 7 and rack 2 8 can be limited, so as to prevent rack 1 7 and rack 2 8 from moving up and down and disengaging from side end gear 6. At the same time, the slider 12 is slidably connected in the slide groove 3, which can also improve the stability of the movement of the inserting sleeve 11.

[0023] During implementation, the starting motor 4 can drive the rotating rod 5 and the gear 6 to rotate clockwise. At this time, the gear 6 can engage the rack 1 7 and translate to the left, and the gear 6 can engage the rack 2 8 and translate to the right. At this time, the two groups of sleeves 9 and the two groups of inserts 11 are driven to approach. The two groups of sleeves 9 can translate along each straight groove 2, and each slider 12 moves along each slide groove 3, which can facilitate the clamping and fixing of the wheel hub.

[0024] As an implementation method in this embodiment, Figure 4 As shown, the pressing assembly includes two groups of electric telescopic rods 13, which are respectively installed in each sleeve 9, and each insertion tube 11 is inserted with an insertion rod 14. The top of each electric telescopic rod 13 and the top of each insertion rod 14 are fixedly connected with a straight plate 15, and the side ends of each two groups of straight plates 15 are fixedly connected with an arc plate 16. The bottom end of each arc plate 16 is fixedly installed with an anti-slip pad 17. In practice, after the wheel hub is clamped, the two groups of arc plates 16 are located at the top of the wheel cover. At this time, by starting each electric telescopic rod 13, each straight plate 15 can be driven to move downward, and at this time, Drive each arc plate 16 to move downward, at this time each insertion rod 14 moves downward in the insertion tube 11, so that the anti-slip pad 17 at the bottom end of each arc plate 16 presses against the top of the wheel cover, so that the wheel cover and the wheel hub can be fixed, thereby facilitating personnel to perform welding operations on the wheel cover and the wheel hub, so there is no need for personnel to manually fix the position of the vehicle wheel hub and the vehicle wheel cover, thereby avoiding easy harm to the user during the electric welding process, and clamping and fixing by the clamping assembly and the pressing assembly will not cause errors between the wheel hub and the wheel cover, thereby avoiding affecting the quality of the final wheel.

[0025] Working principle: After placing the wheel hub and wheel cover on the top of the fixture table 1, starting the motor 4 can drive the rotating rod 5 and the gear 6 to rotate clockwise. At this time, the gear 6 can engage the rack 1 7 and move to the left, and the gear 6 can engage the rack 2 8 and move to the right. At this time, the two sets of sleeves 9 and the two sets of inserts 11 are driven to approach each other. At this time, the wheel hub can be clamped and fixed. At the same time, the two sets of arc plates 16 are located at the top of the wheel cover. At this time, each electric telescopic rod 13 can be started to drive each straight plate 15 to move down. At this time, each arc plate 16 can be driven to move down. At this time, each insert rod 14 moves downward in the insert tube 11, so that the anti-skid pad 17 at the bottom end of each arc-shaped plate 16 presses against the top end of the wheel cover, so that the wheel cover and the wheel hub can be fixed, thereby facilitating the welding operation of the wheel cover and the wheel hub, and therefore, there is no need for personnel to manually fix the position of the vehicle wheel hub and the vehicle wheel cover, thereby avoiding easy injury to the user during the electric welding process, and clamping and fixing by the clamping assembly and the pressing assembly will not cause errors between the wheel hub and the wheel cover, thereby avoiding affecting the quality of the final wheel.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
