Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the gear shift fork machining on spherical end fixture of simple operation.
The technical solution of the utility model is as follows: a kind of gear shift fork machining on spherical end fixture, it is characterized in that: at the two ends, left and right of base top, symmetry installs stretch oil cylinder, the piston rod of these two stretch oil cylinders stretches out towards relative direction, and the piston rod of each stretch oil cylinder is all connected with push rod, the push rod of the right and left is point-blank; Between two stretch oil cylinders, be provided with locating piece, locating piece is by base fixed support, and described locating piece is provided with positioning core axle, and the axial line of positioning core axle and the axial line of described push rod intersect vertically.
Adopt above technical scheme, base is fixedly mounted on lathe.When needing clamping gear shift fork, first gear shift fork is placed on locating piece, gear shift fork is supported by locating piece, and the upper end of positioning core axle is stretched in the axle sleeve of gear shift fork, then gear shift fork is rotated, two pin-and-holes on gear shift fork axle sleeve are distinguished just to two push rods, then the action simultaneously of two stretch oil cylinders is controlled, two stretch oil cylinders drive two push rods to move towards relative direction, until two push rods stretch in pin-and-hole corresponding on gear shift fork axle sleeve respectively, hold out against in the clamping of the right and left push rod, under the support of locating piece and the fixed middle of positioning core axle act on, the location of gear shift fork can be realized, so that process the bulb of gear shift fork on lathe.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 gear shift fork clamping is good, and clamping efficiency is high.
One end of described push rod is stretched in the piston rod of stretch oil cylinder, and both are threaded, and the end face of the annular boss that push rod is integrally formed and stretch oil cylinder piston rod reclines, and the other end of push rod is conehead structure.Above structure is easy accessibility between push rod and the piston rod of stretch oil cylinder on the one hand; the fastness connected is good; on the other hand; push rod is located the pin-and-hole on gear shift fork axle sleeve by conehead; both combine closely; do not damaging in the prerequisite of pin-and-hole, the reliability that gear shift fork clamps can guaranteed further.
In order to simplify structure, convenient for assembly, described positioning core axle is from the bottom up through base and locating piece, and fit in the bottom boss of positioning core axle and the bottom surface of base, the upper end of positioning core axle exceeds the end face of locating piece.
For the ease of guiding, between the end face of described positioning core axle and periphery, pass through conical surface transition.
In order to make locating piece processing and fabricating easy, it is firm that base is installed, and described locating piece is packet, and fixed by two symmetrical sunk screws and base.
Beneficial effect: the utility model structure is simple, compact, and volume is little, and production cost is low, assembling easily, by the cooperation of the right and left push rod, locating piece and positioning core axle, can realize gear shift fork and accurately locate, and simple operation, the fixing of gear shift fork clamping is good, and clamping efficiency is high.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model is made up of base 1, stretch oil cylinder 2, push rod 3, locating piece 4 and positioning core axle 5 etc.Wherein, install stretch oil cylinder 2 in two ends, the left and right symmetry at base 1 top, the piston rod of these two stretch oil cylinders 2 stretches out towards relative direction, and the piston rod of each stretch oil cylinder 2 is all connected with push rod 3, and the push rod 3 of the right and left point-blank.One end of push rod 3 is stretched in the piston rod of stretch oil cylinder 2, and both are threaded, and the end face of the annular boss that push rod 3 is integrally formed and stretch oil cylinder 2 piston rod reclines, and the other end of push rod 3 is conehead structure.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, be provided with locating piece 4 between two stretch oil cylinders 2, locating piece 4 is packet, and is fixed by two symmetrical sunk screws and base 1, makes locating piece 4 by base 1 fixed support.Locating piece 4 is provided with positioning core axle 5, and the axial line of positioning core axle 5 and the axial line of push rod 3 intersect vertically.Positioning core axle 5 is from the bottom up through base 1 and locating piece 4, fit in the bottom boss of positioning core axle 5 and the bottom surface of base 1, axle body and the locating piece 4 of positioning core axle 5 are fixed, and the upper end of positioning core axle 5 exceeds the end face of locating piece 4, passes through conical surface transition between the end face of positioning core axle 5 and periphery.
