Adopt above technical scheme, base is fixedly mounted on milling machine.When needing location gear shift fork, first gear shift fork is set on guide pillar singly, make the bulb of gear shift fork down, and wavy surface is positioned at topmost, then stretch oil cylinder action is controlled, the piston rod drivening rod of stretch oil cylinder is moved right, until the left end of guide pillar is inserted in by the blind hole of connecting rod right-hand member, and the right side of connecting rod is resisted against on Far Left gear shift fork, by under the effect of stretch oil cylinder, multiple gear shift fork is clamped between connecting rod and positioning seat, thus achieve the location of gear shift fork, so that process the wavy surface of gear shift fork on milling machine.The present invention not only structure is simple, compact, and volume is little, occupies little space, and production cost is low, and assembling is easy, and simple operation, and the fixing of gear shift fork clamping is good, and clamping efficiency is high.Meanwhile, can the wavy surface of the multiple gear shift fork of disposable processing, drastically increase the working (machining) efficiency of gear shift fork wavy surface, and the machining accuracy of the workpiece of clamping on same device is consistent, and the quality of workpiece is easily controlled.Limited block is used for multiple gear shift fork simultaneously spacing, to improve the reliability of gear shift fork location further; Limited block moulding is simple, and be easy to machine-shaping, on base, dismounting is convenient, and it is firm to connect.
In order to simplify structure, facilitate processing and fabricating and assembling, positioning seat is installed firm, described positioning seat is packet, and the bottom of positioning seat embeds in the first adaptive groove on base, and positioning seat is fixed by two bolts worn from top to bottom and base.
In order to simplify structure, facilitate processing and fabricating and assembling, guide holder is installed firm, described guide holder is packet, and the bottom of guide holder embeds in the second adaptive groove on base, and guide holder is fixed by two bolts worn from top to bottom and base.
Install for the ease of guide pillar, prevent guide pillar from rotating, the right-hand member of described guide pillar stretches in positioning seat, both matched in clearance, and the screw worn by radial direction holds out against, and passes through conical surface transition between the left side of guide pillar and periphery.
For the ease of guiding, the aperture of the through hole described guide holder supplying connecting rod pass is tubaeform.
Beneficial effect: structure of the present invention is simple, be easy to assembling, production cost is low, multiple gear shift fork can be realized accurately locate, and simple operation, the fixing of gear shift fork clamping is good, clamping efficiency is high, is conducive to the working (machining) efficiency and the machining accuracy that improve gear shift fork wavy surface.
