Technical field
The utility model belongs to numerical controlled machinery manufacturing technology field, and in particular to a kind of new pattern rolling ball screw mandrel.
Background technology
The ball lead screw drive mechanism that in general large-sized numerical control plant equipment is configured at present, surpass to solve ball screw
Grow produced sagging rock in motion and influence the positioning precision and service life of equipment.Mostly there is following solution method.
A：Increase ball screw diameter, B：Hydraulic support mechanism.Although above solution method can play a role, have certain
Defect.1：Corresponding manufacturing cost increase is a lot, 2：Trueness error can not be fully solved, 3：No matter driven loads weight, will
The limitation of driven length, 4：The movement velocity of transmission mechanism is slow and service life is low.In a word, the above both increases machine
The manufacturing cost and maintenance cost of tool equipment.
Utility model content
The purpose of this utility model is to provide a kind of new pattern rolling ball screw mandrel, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of new pattern rolling ball screw mandrel, including screw mandrel,
The screw mandrel is provided with ball grooves, some regularly arranged balls is provided with ball grooves through the duct in the middle part of nut, duct inner side,
And the plane tangent of ball and screw mandrel, the right-hand member of the nut are provided with shock ring, the shock ring is enclosed on screw mandrel, and shock ring
Fixed with nut, the inner side of the shock ring is provided with telescopic elastic ring, if being connected between the shock ring and elastic ring
Dry damping spring, the left end of the nut are fixed with cushion socket, and the upper surface of the cushion socket is set to the arc to be matched with screw mandrel
Face, the cushion socket is interior to be provided with some elastic supporting member for supporting optical member.
Preferably, the internal voids of the cushion socket are filled with energy-absorbing particle.
Preferably, the surface of the screw mandrel and the cambered surface of cushion socket are brought into close contact.
Preferably, the elastic supporting member for supporting optical member is spring or elastic.
Technique effect of the present utility model and advantage：The new pattern rolling ball screw mandrel, screw mandrel is when moving back and forth, caused by screw mandrel
Rock by the shock ring at nut both ends and cushion socket absorption, greatly reduce the degree that screw mandrel rocks, improve the motion of screw mandrel
Precision.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of new pattern rolling ball screw mandrel as Figure 1-3, including screw mandrel 1, the screw mandrel 1 pass through
The duct at the middle part of nut 2, duct inner side are provided with ball grooves 3, some regularly arranged balls 4, and ball 4 are provided with ball grooves 3
With the plane tangent of screw mandrel 1, the right-hand member of the nut 2 is provided with shock ring 5, and the shock ring 5 is enclosed on screw mandrel 1, and shock ring 5
Fixed with nut 2, the inner side of the shock ring 5 is provided with telescopic elastic ring 8, is connected between the shock ring 5 and elastic ring 8
There are some damping springs 7, the left end of the nut 2 is fixed with cushion socket 6, and the upper surface of the cushion socket 6 is set to and the phase of screw mandrel 1
Identical cambered surface, the cushion socket 6 is interior to be provided with some elastic supporting member for supporting optical member 9.
Further, the internal voids of the cushion socket 6 are filled with energy-absorbing particle.
Further, the surface of the screw mandrel 1 and the cambered surface of cushion socket 6 are brought into close contact.
Further, the elastic supporting member for supporting optical member 9 is spring or elastic.
A kind of new pattern rolling ball screw mandrel provided by the utility model, screw mandrel 1 when moving back and forth, rock caused by screw mandrel 1 by
The shock ring 8 and cushion socket 6 at the both ends of nut 2 absorb, because screw mandrel 1 is close to the cambered surface on elastic ring 8 and cushion socket 6, screw mandrel 1
Shake is absorbed by damping spring 7 and elastic supporting member for supporting optical member 9 caused by motion, thus greatly reduces the degree that screw mandrel 1 rocks, carries
The high kinematic accuracy of screw mandrel 1.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
