[0047] like Figure 1-4 As shown, a vehicle wheel cover installation fixture of the utility model comprises a support platform 1, a pressure arm 2, a cylinder 3, a universal ball 4, a jackscrew 5, a hand screw 6 and an air bag 7.

[0048] Among them, the pressure arm 2 is arranged on the side of the support platform 1, and the middle section or the lower middle position of the pressure arm 2 is hinged to the side of the support platform 1, the upper end of the pressure arm 2 is arranged above the support platform 1, the output end of the cylinder 3 is hinged to the lower end of the pressure arm 2, and the other end is hinged to the side of the support platform 1. Specifically, the first hinge plate 10 and the second hinge plate 11 are fixedly arranged on the side of the support platform 1, the middle section or the lower middle position of the pressure arm 2 is hinged to the end of the first hinge plate 10 away from the support platform 1, the end of the cylinder 3 away from the pressure arm 2 and the end of the second hinge plate 11 away from the support platform 1 are hinged, the airbag 7 is screwed to one end of the hand screw 6, the hand screw 6 passes through and is screwed to the screwed universal ball 4, the universal ball 4 is rotatably arranged on the pressure arm 2, and the top screw 5 is screwed to the pressure arm 2 for fixing the universal ball 4.

[0049] The support platform 1 includes a base and a mold platform. The base is fixed in the welding chamber of the ultrasonic welding machine. The mold platform is detachably arranged on the top of the base by bolt fixing. The shape of the top of the mold platform is adapted to the shape of the automobile wheel cover. The first hinge plate 10 and the second hinge plate 11 are both welded to the side of the base and are located below the mold platform. When the cylinder 3 is working, its output end extends out to drive the pressure arm 2 to flip vertically to realize the clamping action. During clamping, the airbag 7 contacts the automobile wheel cover to be welded. After installation, the automobile wheel cover to be welded is welded by ultrasonic welding.

[0050] The airbag 7 is arranged between the support platform 1 and the pressing arm 2. The flexibility of the airbag 7 facilitates flexible clamping of the automobile wheel cover to be welded, so that the automobile wheel cover to be welded is not easily deformed after installation, which is beneficial to improving the quality of the product after welding.

[0051] In the above structure, the air cylinder 3 may also be replaced by an electric push rod, which drives the pressing arm 2 to flip vertically.

[0052] Since the die table is detachable, when processing other types of automobile wheel covers, only the corresponding die table needs to be replaced, and then the abutment angle of the hand screw 6 is adjusted, without the need to replace the tooling as a whole, which is more convenient.

[0053] In order to improve the firmness of the automobile wheel cover to be welded after installation, a plurality of spherical holes 201 are arranged through the upper end of the pressure arm 2 along a first preset direction, and the first preset direction is the normal direction of the top surface of the support platform 1, and the plurality of spherical holes 201 are arranged equidistantly along the contour line of the pressure arm 2, and a universal ball 4 is rotatably set in each spherical hole 201, wherein the diameter of the universal ball 4 is larger than the vertical thickness of the pressure arm 2, which can prevent the universal ball 4 from falling off the pressure arm 2. This structure facilitates the installation of hand screws 6 at different positions of the pressure arm 2, thereby achieving support at different positions and improving the firmness of the wheel cover to be welded after installation.

[0054] In the above structure, the top screw 5 is threadedly connected to one side of the upper end of the pressure arm 2, and one end of the top screw 5 selectively abuts against the side of the universal ball 4 to fix the universal ball 4.

[0055] When the top screw 5 is not in contact with the universal ball 4, the universal ball 4 can rotate in the spherical hole 201 to adjust the angle of the hand screw 6. When the top screw 5 abuts against the universal ball 4, the universal ball 4 cannot rotate in the spherical hole 201. By tightening the top screw 5, the direction of the hand screw 6 can be locked to keep it at a fixed abutting angle.

[0056] The hand screw 6 passes through the universal ball 4 along a first preset direction and is threadedly connected, the first preset direction being the normal direction of the top surface of the support platform 1. Specifically, a second threaded hole 401 is provided on the universal ball 4, wherein the second threaded hole 401 passes through the center of the universal ball 4 along the center line of the universal ball 4, one end of the hand screw 6 is threadedly connected to the second threaded hole 401, and screwing the hand screw 6 can change its relative position with the universal ball 4, and through the threaded cooperation of the hand screw 6 and the universal ball 4, and through the rotation cooperation of the universal ball 4 and the pressure arm 2, the direction and pressing force of the hand screw 6 can be adjusted, so that the wheel cover of the automobile to be welded is not easily deformed after installation, which is beneficial to improving the quality of the product after welding. Specifically, screwing the hand screw 6 can adjust the force of the wheel cover of the automobile to be welded. Specifically, when a larger resistance force is needed, the hand screw 6 is screwed to reduce the distance between the airbag 7 and the support platform 1. Conversely, when a smaller resistance force is needed, the distance between the airbag 7 and the support platform 1 is increased.

[0057] In the structure of a vehicle wheel cover installation fixture of the utility model, the airbag 7 includes a base 71 and a bag body 72, wherein:
