Abstract
The utility model relates to the processing and positioning technology of automobile synchronizer gear hub slots, in particular to a positioning device for a tri-slot broaching special machine. A positioning device adopting a fixed pin for positioning has one problem that the outer gear processing size (the distance over bars) of a gear hub has a certain variation, thereby gaps exist when some workpieces with small outer gear processing sizes (distances over bars) when in positioning, and the true positions of three slots are difficult to be ensured. The positioning device comprises a positioning pin arranged inside a positioning pin supporting seat; the positioning pin and the positioning pin supporting seat are in sliding fit; a spring is arranged at one end of the positioning pin; and the positioning pin moves forwards or backwards by shifting a lever handle installed on the positioning pin supporting seat.
Description
Technical field
The utility model relates to automobile synchronizer tooth hub groove processing location technology, particularly a kind of three-flute special plane positioner that draws.
Background technology
The very crucial place of processing tooth hub three-flute is the location of workpiece, because there is the position relation at these three grooves and tooth hub external tooth and center, hole, can the three-flute of being processed meet the requirements of position degree precision, with the location whether direct relation is arranged rationally.Be originally and adopt the steady pin location, this mode is fairly simple, operation also smoothly, but a problem is arranged: the external tooth processing dimension of tooth hub (striding the rod distance) has certain variation, some outer teeth size (striding the rod distance) will be gapped when little workpiece is located like this, then is difficult to guarantee the position degree of these three grooves.
The utility model content
The utility model purpose little three-flute special plane positioner that draws that provides and a kind ofly eliminate gap between workpiece and the alignment pin, takes up room.
The utility model adopts technical scheme: a kind of three-flute special plane positioner that draws, comprise alignment pin, alignment pin is arranged in the alignment pin bearing, is slidingly matched between them, alignment pin one end is with spring, and alignment pin is stirred and advanced or retreat by being installed on the thick stick formula of shouldering handle on the alignment pin bearing.
The alignment pin bearing is in the same place by bolted by alignment pin upper bracket and alignment pin undersetting.
The utility model adopts and shoulders thick stick formula alignment pin, has eliminated the gap, location, can use in less relatively place in the locus, and because bumper structure, rapid operation, convenient are shouldered in employing; Because three groove time processing improve 3-3.5 doubly than plane bench working (machining) efficiency, dimensional accuracy is also high.
Description of drawings
Accompanying drawing is the utility model structural representation.
1 alignment pin undersetting among the figure, 2 alignment pins, 3 springs, 4 shoulder thick stick formula handle, and 5 shoulder the thick stick axle, 6 alignment pin upper brackets, 7 workpiece (tooth hub).
The specific embodiment
Shouldering thick stick formula handle is contained in and shoulders on the thick stick axle, and insert in the groove of alignment pin, promoting handle like this and just can drive alignment pin and move forward and backward, alignment pin withstands under the effect of spring in the teeth groove of workpiece (tooth hub), when needs take out workpiece, stir shoulder thick stick formula handle can pin positioned apart and workpiece.
Shoulder thick stick formula loose pin and eliminated the gap, location, can use in less relatively place in the locus, and because bumper structure, rapid operation, convenient are shouldered in employing.Guaranteed normally to use at the LG5110KT-1250 vertical internal broaching machine, three groove time processing improve 3-3.5 doubly than plane bench working (machining) efficiency, also meet the demands through facts have proved dimensional accuracy.
Claims (2)
1. one kind is drawn three-flute special plane positioner, comprise alignment pin, it is characterized in that: alignment pin is arranged in the alignment pin bearing, is slidingly matched between them, alignment pin one end is with spring, and alignment pin is stirred and advanced or retreat by being installed on the thick stick formula of shouldering handle on the alignment pin bearing.
2. according to the described a kind of three-flute special plane positioner that draws of claim 1, it is characterized in that: the alignment pin bearing is in the same place by bolted by alignment pin upper bracket and alignment pin undersetting.
