Embodiment Construction
[0017] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:
[0018] combine figure 1 — image 3 As shown, a cantilever clamp assembly for reverse gear shifting is mainly composed of a base plate 1, a workpiece mounting block 2, a positioning base 13, a positioning base support block 14, and four quick clamping assemblies arranged side by side at intervals from left to right B composition. The four quick clamping assemblies B are respectively used to clamp four workpieces, so it is called the reverse gear shift cantilever clamp assembly.
[0019] The positioning base 13 is installed above the bottom plate 1 through the positioning base support block 14, thereby leaving a closed space between the positioning base 13 and the bottom plate 1 for arranging oil pipelines. Quick clamping assembly B is mainly composed of workpiece installation block 2, V-shaped positioning block 3, limit fixing block 4, elastic top tight...

The invention discloses a gear reversing and shifting cantilever clamp combination. The gear reversing and shifting cantilever clamp combination comprises a bottom plate, a positioning base, a positioning base supporting block and two rapid clamping assemblies sequentially arranged side by side from left to right in a spaced manner. Two positioning shafts on workpiece positioning blocks are inserted in corresponding installation holes in workpieces respectively. A hard alloy block is welded to each inclined face of a V-shaped opening in each V-shaped positioning block. The workpieces are pressed by the hard alloy blocks from the left side and the right side of the rear portions of the workpieces. Semicircular notches are formed in the ends of pressing plates. Oil hydraulic swing clamp cylinders drive the pressing plates to rotate so that the ends of the pressing plates can be pressed on the upper end faces of the rear right portions of the workpieces. Locking threaded rods horizontally and obliquely penetrate locking fixing blocks to abut against the left front walls of the workpieces. The execution ends of lever type hydraulic oil cylinders abut against the center positions of the front portions of the workpieces. The cantilever ends of the workpieces are clamped through the locking fixing blocks and elastic ejecting mechanisms. The workpieces can be rapidly and accurately clamped and positioned when the gear reversing and shifting cantilever clamp combination is applied to a vertical machining center; and the number of clamps and the number of clamping times are decreased, the work efficiency is improved, and the labor cost is reduced.
Description
technical field [0001] The invention relates to a processing fixture for transmission parts, in particular to a cantilever fixture combination for reverse gear shifting. Background technique [0002] The processing of the reverse gear shift cantilever needs to go through multiple processes, including processing on CNC lathes, honing machines, and vertical drilling machines. The existing problems are: many times of clamping, long circulation time, easy to cause repeated positioning errors and bump damage ;Each process requires one person to operate, and requires the cooperation of multiple operators to complete. Contents of the invention [0003] The present invention aims to provide a cantilever fixture combination for reverse gear shifting specially used in vertical machining centers. After the clamping is completed, the vertical machining center will process it to replace the CNC lathe, honing machine, and vertical drilling machine equipment in the traditional processing...
