Abstract
The utility model belong to the technical field of manufacturing of motorcycle engine case bodies, and particularly relates to a locating device of a crankshaft hole and a camshaft hole of a motorcycle engine case body. The locating device of the crankshaft hole and the camshaft hole of the motorcycle engine case body comprises a chuck, a taper locating sleeve and a guide pillar, wherein the taper locating sleeve is fixed on the chuck, the guide pillar is coaxial with the taper locating sleeve and is matched with the taper locating sleeve in a sliding mode, the other end of the taper locating sleeve is connected with one end of a reset spring, and the other end of the reset spring is connected with a flange plate. Therefore, when the crankshaft hole is machined in a finishing mode, the position tolerance of the entire device can be determined, the position tolerance of the locating device is set as the datum to locate the position tolerance of the crankshaft hole of a workpiece, and the high location accuracy of the crankshaft hole is guaranteed. When the finish machining of the crankshaft hole is finished, the crankshaft hole and planar location are used for machining the camshaft hole, two times of machining are achieved through one-time clamping, and the phenomena that the distance between the crankshaft hole and the camshaft hole is affected by errors of repeated location in the past, the variation of the center distance of a machined product exceeds the tolerance requirement is brought about, and the percent of pass is low are avoided.

Technical field
The utility model belongs to engine case of motorcycle and makes the field, relates in particular to the positioner of a kind of engine case of motorcycle crankshaft hole and camshaft hole.
Background technology
Crankshaft hole in the engine case of motorcycle class part, camshaft hole etc. all are one of crucial processing contents, have important effect in engine, and these hole in piece part must possess higher precision, otherwise directly have influence on performance, precision and the life-span of engine.
But at the crankshaft hole of existing engine case of motorcycle in the processing of camshaft hole, crankshaft hole is at mould assembling face, camshaft hole first at mould assembling face fine finishining crankshaft hole, is located with mould assembling face pin-and-hole and face overleaf again, the camshaft hole at the processing back side, main existing problems: there is certain error dowel hole and crankshaft hole position, and secondary clamping, resetting error effect two pitch-rows, cause converted products centre-to-centre spacing to change and surpass tolerance, qualification rate is low.
The utility model content
The utility model provides the positioner of a kind of crankshaft hole and camshaft hole, when the processing Motorcycle Boxes, can improve the positioning accuracy of crankshaft hole and camshaft hole.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: the positioner of engine case of motorcycle crankshaft hole and camshaft hole comprises chuck, tapering positioning sleeve, lead, the tapering positioning sleeve is fixed on the chuck, lead is slidingly matched with the coaxial setting of tapering positioning sleeve and with the tapering positioning sleeve, the other end of tapering positioning sleeve connects an end of back-moving spring, the other end mounting flange of back-moving spring.
Adopt technique scheme, in the utility model, when the fine finishining crankshaft hole, workpiece is inserted in the tapering positioning sleeve, because the tapering positioning sleeve is fixed on the chuck, lead is slidingly matched with the coaxial setting of tapering positioning sleeve and with the tapering positioning sleeve, the position of related features of whole like this positioner is determined, position of related features take the position of related features of positioner as the crankshaft hole of origin reference location workpiece, guaranteed the high position precision of crankshaft hole, after crankshaft hole fine finishining is finished, with crankshaft hole and face location machining cam axis hole, like this with clamped one time, reach the purpose of twice processing, avoided in the past because resetting error effect two pitch-rows cause converted products centre-to-centre spacing to change and surpass tolerance, qualification rate is low; According to the degree of depth of crankshaft hole needs processing on the workpiece, the tensile elongation of regulating back-moving spring.
Further, described tapering positioning sleeve is decided to be 0 o～3o according to the process requirements of different workpiece with range of taper.
Further, the inside of described tapering positioning sleeve and lead is provided with alloy-layer, has strengthened the abrasion resistance of positioner, thereby improves the service life of positioner.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the positioner of the utility model engine case of motorcycle crankshaft hole and camshaft hole.
