The using effect of indexing cam mechanism.The bearings at both ends (3) of globoid cam rotary shaft (5) is often filled with eccentric bushing (4) and is used for coordinating
The back lash between cam and index dial is adjusted, gap need to be eliminated by two eccentric bushings (4) of synchronous adjustment.It is unsuitable
Adjustment can reduce indexing accuracy, impact, noise occur, damage ferguson cam mechanism, and be not achieved expected rotating speed and
Load capacity, so as to shorten the service life of indexing mechanism.Globoid cam is cam cutting assembly technology system with eccentric bushing adjusting apparatus
The important component of system is the important process equipment in globoid cam manufacture.Cam is direct with eccentric bushing adjusting apparatus
Influence quality, labor intensity, productivity and the production cost of cam cutting assembly.There is presently no arc surfaced indexing cam machines
Structure special synchronous eccentric bushing adjusting apparatus is only limitted to realize unilateral adjustment, unilateral side adjustment easily distortion to eccentric bushing with general tool
Globoid cam axis, and this adjustment tool depends on worker's manual setting, and cannot be guaranteed that both sides eccentricity is completely the same.It is existing general
During logical tool adjustment, time-consuming, labour-consuming is not suitable for high-volume process and assemble, therefore it is necessary to improve for pole.
Utility model content
The technical problems to be solved in the utility model is：A kind of arc surfaced indexing cam eccentric bushing synchronous adjustment dress is provided
It sets, which can improve the assembling quality of ferguson cam mechanism, reduce
Labor intensity improves productivity.
The utility model is adopted the technical scheme that solve technical problem present in known technology：
A kind of arc surfaced indexing cam eccentric bushing synchronizing controls, the arc surfaced indexing cam include：Index dial (1),
Globoid cam (2), bearing (3), eccentric bushing (4) and globoid cam rotary shaft (5)；It is characterized in that：The same step of eccentric bushing
Engagement positions include connection axis pin (7), and the length of the connection axis pin (7) is not less than the length of globoid cam rotary shaft (5)；Institute
The both ends for stating connection axis pin (7) are separately connected there are one open spanner (6)；Each open spanner (6) includes a connecting rod, connecting rod
One end be provided with " C " shape plate of clamping eccentric bushing (4), the connecting rod with axis pin (7) connection, the other end of connecting rod is connect
It is connected as one with the centre position of " C " shape plate；The centre position of the connection axis pin (7) is equipped with synchronous adjustment handle (8).
Further：The both ends of the surface of the connection axis pin (7) are the rectangular of a × a, and the side wall of the connecting rod offers internal diameter
For the square hole of a × a.
Further：The synchronous adjustment handle (8) is the cylinder that diameter is equal to R；In the connection axis pin (7)
Between position offer the circular hole that internal diameter is equal to R, one end of the synchronous adjustment handle (8) is inserted into after circular hole and connect axis pin (7)
Connection.
The utility model has the advantages and positive effects of：
By using above-mentioned technical proposal, in use, first by open spanner parallel inserted in connecting on axis pin, by same step
Whole handle is plugged in the circular hole in the middle part of connection axis pin.Then it will insert that the synchronizing controls that finishes is parallel to be caught in step 1
In the plane of eccentric bushing, synchronizing controls is blocked.Last both hands agitate downwards synchronous adjustment handle, make globoid cam rotary shaft
Realization is vertically moved, to realize the synchronous adjustment in the gap between globoid cam and index dial.This patent can improve arc
Face index cam process and assemble quality improves productivity, reduces labor intensity and production cost.
