Detailed description of the invention
The object of the present invention is to provide a kind of Shaft drawer, the structural design of this Shaft drawer can solve the problem of complex procedures when using Shaft drawer effectively.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-Fig. 2, Shaft drawer provided by the invention, comprise screw rod 1, nut sleeve 6 and inner sleeve 2, wherein one end of screw rod 1 is link 11, and its link 11 can be threaded with the screwed hole of axle 8 axle head to be removed.Nut sleeve 6 is set on screw rod 1, and nut sleeve 6 and screw rod 1 threaded engagement.Inner sleeve 2 and nut sleeve 6 are rotationally connected, and namely inner sleeve 2 and overcoat can relatively rotate, and cannot move to axial, and one end of inner sleeve 2 can be against on the shaft coupling piece 9 of axle 8 to be removed, and inner sleeve 2, nut sleeve 6 and screw rod 1 are coaxially arranged.Wherein, axle 8 to be removed is the axle that will extract, and the shaft coupling piece 9 of axle 8 to be removed is the parts be connected with axle.
When applying Shaft drawer provided by the invention, first by the head screwed hole of the link 11 precession axle 8 to be removed of screw rod 1, screw rod 1 is fixedly connected with axle 8 to be removed, then one end of inner sleeve 2 is made to be against on the shaft coupling piece 9 of axle 8 to be removed, then directly rotating nut overlaps 6, nut sleeve 6 is made to produce the power of close axle, and nut sleeve 6 and inner sleeve 2 are rotationally connected, relatively there is not axial displacement in both, and inner sleeve 2 is against on the shaft coupling piece 9 of axle 8 to be removed, therefore nut sleeve 6 can only be rotated and axial displacement can not be occurred, therefore nut sleeve 6 is rotated and is made screw rod 1 produce power away from axle 8 to be removed, therefore in the process of nut sleeve 6 rotation, screw rod 1 moves to the direction away from axle 8 to be removed gradually, and then drive axle 8 to be removed to depart from shaft coupling piece 9 on it, realize the dismounting of axle and the connector on it.Setting like this, operation is more simple and convenient.Inner sleeve 2 is against on shaft coupling piece 9 in addition, instead of clamps shaft coupling piece 9, and inner sleeve 2 need not arrange larger volume.
Inner sleeve 2 can be straight-tube shape, and one end of inner sleeve 2 can be set in the outside of nut sleeve 6, and inner sleeve 2 like this only can cover the local of nut sleeve 6, so that select nut sleeve 6.Certainly, one end of inner sleeve 2 also can be set in the inner side of nut sleeve 6.
In this Shaft drawer, the screw rod 1 of moving axially through of axle is converted to rotation with nut sleeve 6, and the rotation of drive nut cover 6 is relatively more laborsaving, and then it is more laborsaving to make to pull out axle process.And according to actual axial displacement of pulling out axle process axis, can arrange the pitch of screw rod, the axial displacement as axle can select more greatly the screw rod compared with coarse pitch, the less screw rod can selected compared with fine pitch of the axial displacement as axle is in this no limit.
Further, in order to optimize technique scheme further, this Shaft drawer can also comprise support set 10, and one end of support set 10 can offset with inner sleeve 2, and the other end can offset with the shaft coupling piece 9 on axle 8 to be removed.When so carrying out pulling out axle, one end of support set 10 directly can be offseted with inner sleeve 2, the other end directly offsets with the shaft coupling piece 9 on axle 8 to be removed, and then rotating nut overlaps 6, so make the connection space between inner sleeve 2 and nut sleeve 6 increase, be more convenient to both installations.Further, support set 10 can be cylindric, makes the different support set of multiple length 10, and then can carry out selecting suitable support set 10 to carry out pulling out axle according to the length of axle.
Further, one end of support set 10 can removably connect with inner sleeve 2, and support set 10 and inner sleeve 2 are coaxially arranged, and wherein one end of support set 10 with one end clamping of inner sleeve 2 or can be threaded.
In addition, the outer wall of nut sleeve 6 can be fixedly connected with link 4, inner sleeve 2 is connected by bearing 3 with link 4, so realize being rotationally connected between nut sleeve 6 and inner sleeve 2 by link 4 and bearing 3, more be convenient to the connection between nut sleeve 6 and inner sleeve 2, the diameter of inner sleeve 2 can also be made comparatively large, be more prone to accordingly be against on the shaft coupling piece 9 of axle 8 to be removed.In order to prevent inner sleeve 2 and nut sleeve 6 from moving to axial, thrust bearing 3 can be used to be connected with inner sleeve 2 by link 4.
Further, link 4 can overall be taper, and the larger one end of its diameter is connected by bearing 3 with inner sleeve 2, so can make the diameter of inner sleeve 2 comparatively greatly, and the diameter of nut sleeve 6 is less than the diameter of inner sleeve 2.Certainly, link 4 also can be straight-tube shape, in this no limit.In addition, link 4 can arrange hollow out, so that rotate this link 4, and then realize rotating nut cover 6.
Preferably, also comprising the first handle 5 be arranged in nut sleeve 6, so can realize by rotating first handle 5 when rotating nut overlaps 6, more laborsaving.First handle 5 can be arranged perpendicular to the axis of nut sleeve 6.Further, first handle 5 and nut sleeve 6 are for removably connecting, and the quantity of first handle 5 is multiple, multiple first handle 5 can distribute along the circumference of nut sleeve 6, namely first handle 5 can be dismantled when transporting, more be convenient to transport, and the installation quantity of first handle 5 can be rotated according to the angle rotated.
In addition, the other end of screw rod 1 is also provided with second handle 7, and so can pass through second handle 7 when rotary screw 1, second handle 7 can be arranged perpendicular to the axis of screw rod 1.Second handle 7 and screw rod 1 can removably connect, and also can weld.
Wherein, in order to avoid the link 11 pulling out screw rod 1 in axle process departs from the screwed hole of axle 8 to be removed, the thread rotary orientation of link 11 can be made identical with the thread rotary orientation of screw body.If when so screw rod follows nut sleeve rotation, the link of screw rod and the connection of axle to be removed can be more fastening, can not depart from axle 8 to be removed.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
