The invention provides a universal curved surface clamp, comprising an upper clamping part and a lower clamping part, a lifting part is arranged between the upper clamping part and the lower clamping part, and the lifting part is used for adjusting the upper clamping part The distance between the clamping part and the lower clamping part, the workpiece to be processed is arranged between the upper clamping part and the lower clamping part; the upper clamping part and the lower clamping part are provided with a plurality of clamping rods, and the upper The clamping rods of the clamping part correspond to the clamping rods of the lower clamping part, and the clamping rods are respectively provided with elastic components, and the clamping rods of the upper clamping part and the lower clamping part are formed by elastic components The clamping surface corresponding to the workpiece to be processed. The spring rigidity of the general-purpose curved surface fixture described in the invention is moderate, and the pre-tightening force is small so that the workpiece is not damaged, and flexible clamping is realized.
Description
technical field [0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a universal curved surface fixture. Background technique [0002] In the field of automobiles, whether it is the exterior sheet metal shape or the interior parts, the automobile structure mostly appears in the form of curved surfaces. fixtures. With the introduction of new models and rapid replacement in the automotive field, if special fixtures are made for various curved surfaces of different structures, although the fixtures are directly processed in place, the reserved space is small, and the precision is high, the special fixtures have poor versatility and are not conducive to mass production. Or unified purchase and inventory storage, resulting in high production and management costs, low utilization rate, and serious waste of materials and production capacity. Contents of the invention [0003] In view of this, the present invention aims...
