Referring to figs. 1 to shown in Fig. 7, a kind of coil winding machine mainshaft mechanism provided by the utility model, including：Main spindle box 10, master
Axle 20, bearing, axle sleeve 50 and bearing cap 60, the main spindle box 10 are provided with a mounting hole 11, the middle area of the mounting hole 11
The aperture in domain is less than the aperture of two end regions, and then forms the position limiting structure of limited step (111 and 112), and the bearing is
Deep groove ball bearing, end bearing 30 and rear end before the bearing is separately positioned on the both ends of the mounting hole of main spindle box and then formed respectively
Bearing 40, it is two that the preceding end bearing 30 is identical with the number of bearings of rear end bearing 40, and the main shaft 20 is arranged in main shaft
In the mounting hole 11 of case 10 and in the inner ring of preceding end bearing 30 and rear end bearing 40, and then main shaft is rotatably provided in by bearing
On case 10.
The axle sleeve 50 is set on the main shaft 20 between preceding end bearing 30 and rear end bearing 40, the axle sleeve 50
Before both ends contact at successively on the inner ring of end bearing 30 and rear end bearing 40.The axle sleeve 50 and the mounting hole 11 of main spindle box 10
Set between inwall in spacing, to ensure contactless friction between axle sleeve 50 and main spindle box 10.
The first contact part 21 and second is further respectively had on the main shaft 20 in preceding end bearing 30 and the outside of rear end bearing 40
Contact part 71, the inner ring of end bearing 30 and rear end bearing 40 before the contact part 71 of the first contact part 21 and second contacts at respectively
On, and then the preceding position of end bearing 30 and rear end bearing 40 on main shaft 20 is gripped jointly with axle sleeve 50, prevent bearing from existing
Skew is produced on main shaft 20.In this specific embodiment, the first contact part 21 before contacting on the inner ring of end bearing 30 is main shaft
Integrated formed structure, the second contact part 71 contacted on the inner ring of rear end bearing 40 are the synchronizing wheel 70 being sheathed with main shaft 20
Extended structure.Using the extended structure of synchronizing wheel 70 as the second contact part 71 on the inner ring for contacting at rear end bearing 40,
Synchronizing wheel 70 is removably socketed in the end of main shaft 20, and its specific mode is：The end of main shaft 20 opens up fluted 22, described
Synchronizing wheel 70 is provided with a sets of holes 72, and the sets of holes 72 extend neck 73 also into synchronizing wheel, are embedded together in the groove 22 of main shaft 20
Step wheel key 80, the sets of holes 72 of the synchronizing wheel 70 are socketed on main shaft 20, and its synchronizing wheel key 80 is also embedded in the card of the synchronizing wheel 70
In groove 73, to be formed fixedly sleeved；This is conventional socket mode in the art.
The bearing cap 60 covers the outer ring of end bearing 30 at the front-end port of mounting hole 11 and before pressing, makes front end axle
Hold 30 outer ring to be fixed between bearing cap 60 and limited step 111, and then the outer ring of preceding end bearing 30 is completely fixed in
On main spindle box 10, it is ensured that main shaft 20 in the axial direction can not play, as shown in Figure 5.Thereafter the outer ring of end bearing 40 is in axial direction
Do not limited on direction and then form free end, as shown in fig. 6, the outer ring of rear end bearing 40 and the limited step of main spindle box 10
It is in gap setting between 112, the completely open outer ring for ensuring rear rear end bearing 40 of opposite side in the axial direction can be freely movable.
The structure used by the present embodiment, compares with the prior art in background technology, justifies in coil winding machine main shaft and jumps
In dynamic degree detection data, the circle beating degree installed for the first time is 0.001mm；After 1000rpm break-in twenty four hours, existing master
The circle beating degree of axle construction is 0.003mm, and the circle beating degree of the main axle structure of this programme is 0.002mm；In 1500rpm break-ins
After twenty four hours, the circle beating degree of existing main axle structure is 0.005mm, and the circle beating degree of the main axle structure of this programme is
0.003mm；After using one month, the circle beating degree of existing main axle structure is 0.01mm, and the circle of the main axle structure of this programme
Beating degree is 0.006mm；After using half a year, the circle beating degree of existing main axle structure is 0.016mm, and the main shaft knot of this programme
The circle beating degree of structure is 0.01mm；After using 1 year, the circle beating degree of existing main axle structure is 0.018mm, and this programme
The circle beating degree of main axle structure is 0.011mm.It can thus be concluded that going out, improved, can largely changed by the structure of this programme
It is apt to the circle beating degree of the main axle structure, to ensure the stability of the main axle structure and service life.
In the present embodiment, the bearing is deep groove ball bearing, and preceding end bearing 30 and the number of bearings of rear end bearing 40
Identical is two；Deep groove ball bearing is used to the angular contact bearing in the structure relative to prior art, is reduced to assembling
Requirement, make assembling simpler.Preceding end bearing 30 with the number of bearings of rear end bearing 40 it is identical make main shaft in front and rear stress more
Add uniformly, the intensity bearing more latter than the first two improves a lot, and bearing is preferably born backend synchronization band tensioning production capacity
Radial load, bearing is hardly damaged in the case where running at high speed.Meanwhile in other embodiments, preceding end bearing 30 and rear end bearing
40 number of bearings is not limited to two, one or more can be specifically set according to actual size and stressing conditions, as long as preceding
End bearing is identical with the number of bearings of rear end bearing, just no longer illustrates one by one herein.
In the present embodiment, preceding end bearing 30 can prevent that main shaft 20 from being altered in the axial direction by the way of being completely fixed
It is dynamic, in other embodiments, the mode that rear end bearing 40 is fixed, the outer ring of preceding end bearing 30 opens can also be substituted for；Furthermore
, can also be simultaneously open by the outer ring of preceding end bearing 30 and rear end bearing 40 in the case where allowing the slight shift play of main shaft 20
In free end, i.e., as shown in figure 8, when main shaft 20 is offset in the axial direction relative to main spindle box 10, the bearing of its one end
Outer ring is contacted on limited step, limits the further skew of main shaft 20, and then the bearing for limiting the other end departs from main spindle box 10
Mounting hole 11.
By technical scheme provided by the utility model, the preceding end bearing is identical with the number of bearings of rear end bearing, and
The outer ring of at least bearing of one end is not fixed into and forms free end in the axial direction；Be arranged such make main shaft it is front and rear by
In power more uniformly, basis is provided to run at high speed, meanwhile, the outer ring of bearing is in free state in the axial direction, can be effective
Eliminate bearing to expand with heat and contract with cold in the parts caused by generation heating that run at high speed, the rotating speed of increase main shaft can be reached very well and subtracted
The frequency of small damage, by the combination of said two devices, the coil winding machine speed of mainshaft is set to be brought up to by original 15000rpm
18000rpm even more highs；Reduce the frequency of coil winding machine main shaft damage, originally coil winding machine main shaft makes for 24 hours in continuous whole day
It will be damaged successively with after 2-3, the main shaft life-span, which can improve, after structure is improved causes 5-6.Furthermore the outer ring of bearing is in axle
It is in free state on to direction, mismachining tolerance can be eliminated again, changes assembly or disassembly simpler.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
