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 double-station reverse shift cantilever fixture is mainly composed of a base plate 1, a workpiece mounting block 2, a positioning base 13, a positioning base support block 14, and two workpiece clamping mechanisms B arranged side by side. Two workpiece clamping mechanisms B are used to clamp two workpieces respectively, so it is called double-station reverse gear shift cantilever clamp.
[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. The workpiece clamping mechanism B is mainly composed of workpiece mounting block 2, V-shaped positioning block 3, limit fixing block 4, elastic top tightening mechanism 5, locking fixing block 6...

The invention discloses a double-station reverse gear shifting cantilever fixture which comprises a bottom plate, locating bases, locating base supporting blocks and two workpiece clamping mechanisms, wherein the two workpiece clamping mechanisms are mounted left and right in a side-by-side mode. Two locating shafts of each workpiece locating block are inserted into corresponding mounting holes in each workpiece respectively. Hard alloy blocks are welded to each slope of the V-shaped opening of each V-shaped locating block, and each workpiece is pressed from the left side and the right side of the rear portion of the workpiece respectively. Semicircular notches are formed in the ends of each pressing plate, and oil hydraulic rotating cylinders drive the pressing plates to rotate to enable the ends of the pressing plates to press the upper end faces of the rear right sides of the workpieces. Locking screw rods horizontally and obliquely penetrate through locking fixing blocks and then abut against the front left walls of the workpieces. Executing ends of lever type oil hydraulic cylinders abut against the centers of the front portions of the workpieces. The cantilever ends of the workpieces are clamped by limiting fixing blocks and elastic propping mechanisms. The double-station reverse gear shifting cantilever fixture is applied to a vertical machining center and can be used for quickly and precisely clamping and locating the workpieces; the number of fixtures and the frequency of clamping are reduced, so that work efficiency is improved, and labor cost is lowered.
Description
technical field [0001] The invention relates to a processing fixture for parts of a transmission, in particular to a double-station reverse gear shifting cantilever fixture. 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 dual-station reverse gear shift cantilever fixture specially used for vertical machining centers. The processing completed by the drilling machine equipment saves the process and the number of clamping, and improves the production efficiency. [0004] For this reason, the technical solu...
