Description
Technical field
Indexing and detent mechanism technical field to bent axle when this utility model relates to machining crankshafts,
Especially relate to a kind of new type crank indexing positioning device.
Background technology
Machining crankshafts connecting rod neck on crank connecting rod journal lathe, adjust eccentric throw process one turn after
Being accomplished by indexing bent axle, traditional frame mode is to drive snail by rotary worm (gear)
After wheel (gear wheel) turns to the angle needed, the hole, location inserted on mobile dish with bolt axle is come
Reach the purpose that bent axle is indexed.This structure is to the required precision of pin hole position on mobile dish
Higher, the positional precision of pin hole directly affects the machining accuracy of bent axle, and worm and gear is due to gear ratio
Big feature, the angle that worm gear wheel is the least when worm screw rotates a circle, this causes the mistake that bent axle indexes
Journey is relatively time-consuming, and the manufacturing cost of this structure is higher.
Summary of the invention
The purpose of this utility model is to avoid the defect of prior art to provide a kind of new type crank indexing
Positioner, efficiently solves the problem that prior art exists.
For achieving the above object, the technical scheme that this utility model is taked is: described a kind of new type crank
Indexing positioning device, is characterized in including clamp body, described clamp body is correspondingly arranged on index dial,
Index dial is connected with the spindle nose of rhombus pin with the flange end of bent axle by bolt, and it is fixed that clamp body is additionally provided with
Position set, is provided with index pin in positioning sleeve, index pin periphery is provided with compression spring, and index pin outer end sets
It is equipped with locating snap ring and handle, clamp body is provided with gland by nut.
Described index dial carries out just positioning by rhombus pin with the spindle nose of crankshaft flange end, then passes through spiral shell
Bolt is fixedly linked, and index dial is provided with thread form groove.
Described positioning sleeve is arranged in the hole on clamp body, and the endoporus of positioning sleeve is machined with straight trough, point
It is provided with the straight pin corresponding with straight trough on degree pin, makes index pin under straight pin drives by pulling handle
Positioning sleeve moves back and forth, and is held in position towards upper.
Described index dial uses circular pan-like structure, and the front end of index pin is provided with and the tooth on index dial
The tooth form head that shape groove is corresponding.
The beneficial effects of the utility model are: described a kind of new type crank indexing positioning device, its indexing
Dish can go out the thread form groove of different minute of angle according to different Crankshaft Machinings, with adapt to various bent axle indexing and
Location.It is easily worked, easy to make, and the highest precision can be obtained.The tooth form head of index pin
Portion obtains the highest hardness through Quenching Treatment, and head is wear-resisting, improves the service life of index pin.Should
Device has the spy such as simple in construction, easy to adjust, manipulation light and flexible, easy, the low cost of processing and manufacturing
Point.
