Abstract
A kind of mechanical pressure eccentric drive shaft, it includes：Eccentric shaft body, symmetrical two eccentric bushings, bolt and alignment pin, the eccentric shaft that eccentric throw is e is formed with the middle part of described eccentric shaft body to turn, corresponding outer cone and external spline teeth are made on eccentric shaft turns, two eccentric bushings pass through internal conical surface and inner spline gear thereon, turned with eccentric shaft and make corresponding outer cone and external spline teeth is co-operatively installed together, the utility model has configuration aspects reasonable, the precision of regulation is high, at the same parts service life it is high the advantages of.
Description
Technical field
A kind of mechanical pressure eccentric drive shaft is the utility model is related to, belongs to punching machine technical field.
Background technology
It is well-known：Eccentric shaft is the important spare part of punching machine, and punching machine is in order to complete different punching presses
Process task, it is necessary to which from the punching machine of different punching strokes, and the punching stroke of punching machine is by eccentric shaft
What eccentric throw determined, the eccentric throw of the eccentric shaft of existing punching machine is usually changeless, thus, in order to complete not
Same process task, it must just select the different punching machine of punching stroke, it is clear that this can increase the cost of investment of equipment.
Although also there are some punching machines to use the adjustable eccentric shaft of eccentric throw at present, reach the effect of a tractor serves several purposes, it is this kind of
Adjustable eccentric away from eccentric shaft and its punching machine, because configuration aspects are unreasonable, the precision of regulation is not high, while zero
The service life of part is not high.
Utility model content
The purpose of this utility model is：The machinery that a kind of eccentric throw is adjustable and rational in infrastructure, degree of regulation is higher is provided
Press off-centering axle.
Technical scheme is used by the utility model realizes above-mentioned purpose：A kind of described mechanical pressure eccentric drive shaft,
It includes：Eccentric shaft body（1）, symmetrical two eccentric bushings（2）, bolt（3）And alignment pin（9）, described is inclined
Spindle body（1）Middle part be formed with eccentric throw be e eccentric shaft turn（4）, it is characterised in that：Described eccentric shaft turns（4）In
Between sectional position to both sides be a symmetrical cylindrical cone（12）, turned in eccentric shaft（4）Both sides are symmetrically formed with and bias
Axle turns（4）Stepped cylindrical with same axis（5）, described stepped cylindrical（5）The face of cylinder on be formed with external spline teeth（6）,
Apart from eccentric bushing（2）Axis（14）, eccentric throw be E female cone（7）Central axis（13）On position, it is formed with and connects
Female cone（7）With inner spline gear（8）, female cone（7）With cylindrical cone（12）With identical taper, inner spline gear（8）With
External spline teeth（6）Inside and outside it can be intermeshed, two identical eccentric shafts turn（4）Pass through inner spline gear respectively（8）With external splines
Tooth（6）Intermeshing, and female cone（7）With cylindrical cone（12）The mode of cone match is symmetrically mounted at eccentric shaft and turned
（4）On, two eccentric shafts turn（4）Between use bolt respectively（3）And alignment pin（9）Positioning.
When need change eccentric bushing（2）Axis（14）With eccentric shaft body（1）Axis（10）Eccentric throw when, as long as
By two eccentric bushings（2）Unclamp, rotate different angles, it is possible to obtain different eccentric throws.
Beneficial effect：The utility model between engaging member by circular conical surface due to being coordinated, between eliminating between parts
Gap, is done circumferentially positioned by interior external spline teeth, and positioning is reliable, so, the utility model has that configuration aspects are reasonable, the essence of regulation
Degree is high, at the same parts service life it is high the advantages of.
