Abstract
Disclosed is a side-by-side type clamp for end surface milling of reverse and shift gear cantilevers. The side-by-side type clamp comprises a base plate. Two workpieces are clamped by two workpiece clamping mechanisms which are arranged on the base plate side by side in a left-and-right mode respectively, and two locating shafts on each workpiece locating block are inserted into corresponding mounting holes formed in the corresponding workpiece respectively. A hard alloy block is welded on each inclined surface of the V-shaped opening of each V-shaped locating block, and the hard alloy blocks tightly press the workpieces in the directions of the left side and the right side of the position behind the workpieces respectively. An oil pressure rotating angle cylinder drives a press plate to rotate so that the end of the press plate can press the upper end surface of the right rear portion of each workpiece. A locking threaded rod horizontally penetrates through a locking fixing block in an inclined mode and then abuts against the left front wall of each workpiece. The execution end of a lever type oil pressure cylinder abuts against the middle of the front portion of each workpiece. The cantilever end of each workpiece is clamped by a limiting fixing block and an elastic abutting mechanism. The side-by-side type clamp is applied to a vertical machining center, and can quickly and accurately conduct clamping and locating operation on the workpieces. The two workpiece clamping mechanisms are operated by one worker, and therefore the number of clamps and the frequency of clamping are reduced, the working efficiency is improved, and the labor cost is reduced.
