[0002] The dashboard combination switch cover assembly is a crucial component in automotive interiors. It typically features complex curved contours and numerous holes and slots requiring machining. During processing, such as drilling, milling, laser cutting, or inspection, precise and stable positioning and clamping of the cover assembly are essential. Currently, the industry primarily uses dedicated fixed tooling for positioning such irregularly shaped curved workpieces. A single tooling set is usually designed for a single, specific model of cover assembly, with a fixed, non-replaceable positioning seat and relatively fixed clamping positions and angles. However, with the rapid updates and replacements of automotive models, the production of different models requires workpieces to be tilted at specific angles to achieve optimal tool access or machining visibility. Fixed-angle tooling cannot meet these process optimization needs. Summary of the Invention

The support plate has a plurality of positioning holes evenly distributed therein. A contour positioning seat is provided in the positioning holes by means of a locking structure. The contour positioning seat matches the contour of the instrument panel combination switch cover assembly to be machined. The top of the contour positioning seat is provided with a pressing part for positioning the instrument panel combination switch cover assembly on the contour positioning seat. The fixture also includes an adjustment component for adjusting the flip angle of the support plate.

[0005] Preferably, the locking structure is a fastening bolt, and the side end of the support plate has a threaded hole that extends to the positioning hole. The fastening bolt is threaded into the threaded hole and abuts against the contour positioning seat.

[0006] Preferably, the clamping part includes a support rod and a clamping rod. The support rod is fixedly mounted on the contour positioning seat, and the top of the support rod is externally threaded. The clamping rod is threaded onto the top of the support rod and positioned by a locking nut.

[0007] Preferably, the lower end face of the clamping rod is provided with a pad, which mates with the surface of the instrument panel combination switch cover assembly to be processed, and the pad is made of flexible material.

[0008] Preferably, the adjusting assembly includes a lead screw, a moving rod, and a connecting rod. The lead screw is rotatably mounted on the tooling base, the moving rod is threaded onto the lead screw, the tooling base is provided with a slide rod, the moving rod is slidably mounted on the slide rod, one end of the connecting rod is hinged to the moving rod, and the other end of the connecting rod is hinged to the support plate.

[0009] Preferably, the lower end of the tooling base where it is hinged to the support plate is provided with a cavity, and the end of the lead screw passes through the cavity and is coaxially mounted with a handwheel.

[0010] The advantages of this utility model are as follows: by evenly distributing a number of positioning holes on the support plate, and by providing a contour positioning seat in the positioning holes through a locking structure, in conjunction with the clamping part and the adjusting component for adjusting the flipping angle of the support plate, the support plate can be adjusted to the most suitable tilt angle according to the processing requirements, so that the workpiece processing posture can be flexibly optimized.
