Adopt above technical scheme, base is fixedly mounted on milling machine.When needing location gearshift fork, first gearshift fork is set on guide pillar singly, make the bulb of gearshift 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 one gearshift fork, by under the effect of stretch oil cylinder, multiple gearshift fork is clamped between connecting rod and positioning seat, thus achieve the location of gearshift fork, so that process the wavy surface of gearshift fork on milling machine.The utility model 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 gearshift fork clamping is good, and clamping efficiency is high.Meanwhile, can the wavy surface of the multiple gearshift fork of disposable processing, drastically increase the working (machining) efficiency of gearshift 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.
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: the utility model structure is simple, be easy to assembling, production cost is low, under the effect of stretch oil cylinder, by coordinating of connecting rod and positioning seat, multiple gearshift fork can be realized and accurately locate, and simple operation, the fixing of gearshift fork clamping is good, and clamping efficiency is high, is conducive to the working (machining) efficiency and the machining accuracy that improve gearshift fork wavy surface.
