Description
Technical field:
This utility model relates to spring coiling machine technical field, a kind of spring coiling machine mandrel.
Background technology:
Central spindle of the spring diameter and length determine according to rolling the spring being sized, prior art manufactures different length,
The spring of different-diameter needs to change different mandrels, significantly wastes man power and material, if if spring model is relatively more, relatively
Many mandrels can cause the biggest waste, need to improve.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one conveniently roll different lengths, multiple directly
Diameter spring, the spring coiling machine mandrel of highly versatile.
This utility model solves the scheme of described technical problem: a kind of spring coiling machine mandrel, including mandrel body and sleeve,
Described mandrel body front end is provided with spline, and described mandrel body outer wall is provided with symmetrical two in mandrel body axis
Flat key keyway, is provided with A type general flat key, is provided with, in described mandrel body rear end, the flower matched with spline in described flat key keyway
Keyway, this internal spline adjacent position that is positioned at of described mandrel is provided with annular groove, and described annular groove external diameter is more than spline
Maximum gauge, described sleeve is provided with two keyways running through two ends in the axial direction, and said two keyway is with in sleeve
Axisymmetrical is distributed, and between described sleeve lining and the outer wall of mandrel body, tight fit couples, described keyway and A type general flat key
Tight fit couples.
Prominent effect of the present utility model is: utilizes multiple mandrel head and the tail spline to couple and forms the use of various length, significantly
Save cost and improve efficiency, refitting need not have been dismantled, it is only necessary to having used spline to couple at afterbody, having used spline connection
Connect, couple reliable, good stability and positioning precision is high, bearing torque is big, be easy for installation and removal, it is also possible to utilize and change difference
The sleeve of external diameter forms the mandrel of various diameters so that mandrel body can be general, is greatly saved cost, changes dismounting the most very
Convenient, this most internal spline adjacent position that is positioned at of mandrel is provided with maximum straight more than spline of annular groove and annular groove external diameter
Footpath, convenient processing spline, this utility model simple in construction, conveniently roll different lengths, multiple diameter spring, highly versatile,
Reduce cost and improve efficiency, there is the highest economic worth, be worthy to be popularized.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is perspective view of the present utility model.
Fig. 3 is another view stereo structural representation of the present utility model.
Detailed description of the invention:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of technical scheme of this utility model offer: a kind of spring coiling machine mandrel, including mandrel
Body 1 and sleeve 7, described mandrel body 1 front end is provided with spline 2, and described mandrel body 1 outer wall is provided with in mandrel body 1
Two flat key keyways 3 of axisymmetrical distribution, are provided with A type general flat key 4, described mandrel body 1 rear end in described flat key keyway 3
Inside it is provided with the spline 6 matched with spline 2, is positioned at spline 6 adjacent position in described mandrel body 1 and is provided with annular groove 5,
Described annular groove 5 external diameter is more than the maximum gauge of spline 6, and described sleeve 7 is provided with and runs through the two of two ends in the axial direction
Individual keyway 8, said two keyway 8 is symmetrical with the axis of sleeve 7, the outer wall of described sleeve 7 inwall and mandrel body 1 it
Between tight fit couple, described keyway 8 couples with A type general flat key 4 tight fit.
This utility model when in use, utilizes multiple mandrel to carry out head and the tail spline and couples composition various length use,
It is greatly saved cost and improves efficiency, refitting need not be dismantled, it is only necessary to using spline to couple at afterbody, use spline
Couple, couple reliable, good stability and positioning precision is high, bearing torque is big, be easy for installation and removal, it is also possible to utilize and change not
Sleeve 7 with external diameter forms the mandrel of various diameter so that mandrel body 1 can be general, is greatly saved cost, changes dismounting
Also very convenient, it is positioned at spline 6 adjacent position in mandrel body 1 and is provided with annular groove 5 and annular groove 5 external diameter more than spline
The maximum gauge of 6, convenient processing spline 6, this utility model simple in construction, conveniently roll different lengths, multiple diameter spring,
Highly versatile, reduces cost and improves efficiency, having the highest economic worth, be worthy to be popularized.
Finally, embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant skill
The those of ordinary skill in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Changing and modification, the technical scheme of the most all equivalents falls within category of the present utility model, patent protection model of the present utility model
Enclose and should be defined by the claims.
