[0014] Fig. 2 A schematic view of the supporting and positioning device. DETAILED DESCRIPTION

[0015] The utility model will be further explained in detail in combination with the drawings. In the description of the utility model, it is understood that the orientation words such as "up, down" and "top, bottom" and the like indicated orientation or position relationship is usually based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, in the case where no opposite statement is made, these orientation words do not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore, it can not be understood as the limitation on the protection scope of the utility model; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0016] As shown in Figs. 1-2 An automobile wheel cover 100 combined welding fixture, comprising a fixture base 1, a plurality of supporting and positioning devices are installed on the fixture base, the supporting and positioning device comprises a supporting seat 2, a pressing assembly and a positioning assembly;

[0017] The supporting seat is fixedly installed on the fixture base, the pressing assembly comprises a clamping cylinder 3 fixedly installed on the supporting seat, a pressing block 4 is hinged to the cylinder rod end of the clamping cylinder, a rotating arm 5 is rotatably connected between the supporting seat and the pressing block, two pressing blocks 6 are fixedly installed downward on the pressing block, and a supporting block 7 is fixedly installed opposite the pressing block on the supporting seat.

[0018] The positioning assembly comprises a positioning cylinder 8 fixedly installed on the supporting seat, a positioning plate is fixedly installed on the cylinder rod of the positioning cylinder, a positioning arm is fixedly installed on the positioning plate, and a positioning pin 9 is fixedly installed on the positioning arm.

[0019] In this way, the automobile wheel cover is clamped and positioned by the plurality of supporting and positioning devices, and then welding operation is carried out.
