Abstract
The utility model discloses a double-end bolt dismounting device which comprises a sleeve, two or more wedge blocks, a rocker and an elastic annular holder. A port is formed in the annular holder, the wedge blocks penetrates on the annular holder, inclined planes of the wedge blocks are positioned on the outer side, and screw threads are arranged on outboard inclined planes. Interior screw threads matched with the outboard screw threads of the wedge blocks are placed inside the sleeve. A through hole is formed at the lower end of the sleeve, and the rocker penetrates through the through hole. Through mutually cooperation among the wedge blocks, the annular holder and the sleeve, the surface of the free end of a double-end bolt which is to be dismounted is held and clamped by inner side faces of the wedge blocks in rotation and shrink modes, and therefore the purpose that the double-end bolt is dismounted fast is achieved. The operation process of dismounting the double-end bolt is simple, the double-end bolt dismounting device is convenient to use, space effect is little, and a surface screw thread of the double-end bolt cannot be damaged. The double-end bolt dismounting device is especially suitable for being used when a plurality of double-end bolts need to be dismounted.
Description
Technical field
The utility model relates to a kind of assembly tool, and particularly a kind of stud provision for disengagement for stud dismounting use simple to operate, easy to use belongs to mechanical assembling field.
Background technology
In some main equipments, wheel hub is connected with flange and is connected or fixing by stud, and as in wind power generating set, the stud that connects on the wheel hub has tens usually, not only quantity is many, size is large, and stud can't use general spanner to dismantle and install owing to there not being six square head structures, so that stud inefficiency when assembling, take a lot of work, require great effort, even dismantle improperly, and also can cause screw thread or tool damage, safeguard to dismounting and bring very big inconvenience.
How to improve this present situation, make things convenient for the unloading process of stud, want the problem that solves with regard to becoming the utility model.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the utility model aims to provide a kind of simple to operate, easy to use, flexibly stud provision for disengagement of dismounting, to satisfy the dismounting needs of stud, guarantees that the unloading process energy is smooth, safety is carried out.
The utility model is achieved through the following technical solutions:
A kind of stud provision for disengagement comprises sleeve, two or more wedge, rocking bar and elastic annular retainer; Annular retainer is provided with opening; Wedge is through on the annular retainer, and wedge is symmetry shape and evenly distributes; The inclined-plane of wedge is positioned at the outside, and inclined-plane, the outside is provided with screw thread; Be distributed with anti-skidding reticulate pattern on the medial surface of wedge; The annular retainer of wedge both sides is provided with alignment pin; Be provided with the internal thread that matches with the wedge outside screw in the sleeve, the sleeve lower end is provided with through hole; Rocking bar is through on the through hole of sleeve lower end.
Described annular retainer is more than one, and more than one annular retainer is upper and lower horizontally, and wedge is through on the more than one annular retainer simultaneously.
Described annular retainer is the annulus with opening.
Described wedge medial surface is arc, the arc medial surface with treat that the surface of dismounting stud is complementary.
Stud provision for disengagement described in the utility model, utilize cooperatively interacting between wedge, elastic annular retainer and the sleeve, drive wedge by sleeve and in rotary course, form contractive effect, finish the wedge medial surface and treat holding and clamping of dismounting stud movable end surface, thereby finally realize the fast assembling-disassembling of stud.Its process is not only simple to operate, easy to use, can not produce damage to the screw thread on stud surface in the operation, and, also can be in relatively narrow space use, be subjected to space and ambient influnence less, be very easy to the dismounting of stud, use when being particularly suitable for that more stud carried out dismounting.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing 1, Fig. 2 the utility model is further described:
Stud provision for disengagement described in the utility model comprises sleeve 5, four wedges 3, rocking bar 6 and two elastic annular retainers.Wherein, annular retainer is opening annulus 2, and its effect is that wedge 3 positions are relatively fixing, simultaneously, make wedge 3 form symmetry shape and be evenly distributed on the movable end outside for the treatment of dismounting stud 1, and rely on the strain of opening annulus 2, form the chucking of 3 pairs of studs 1 of wedge.In the present embodiment, two opening annulus 2 horizontal upper and lower arrangements, four wedges 3 are through on two opening annulus 2 simultaneously, and four wedges 3 are the crosswise symmetric arrays aloft, and wedge 3 both sides are carried out the position by alignment pin 7 and are fixed.The inclined-plane of wedge 3 is positioned at the outside, and inclined-plane, the outside is provided with screw thread.Wedge 3 medial surfaces are arc, the arc medial surface with treat that the surface configuration of dismounting stud 1 is complementary, and can finally realize the chucking to stud movable end surface.For increasing the frictional force on chucking surface, on the arc medial surface of wedge 3, also be distributed with anti-skidding reticulate pattern.
Sleeve 5 is used for driving wedge 3 rotations, for this reason, is provided with the intilted internal thread 4 that matches with inclined-plane, wedge 3 outside in sleeve, and internal thread 4 interconnects sleeve 5 and wedge 3.For ease of operation, the lower end of sleeve 5 also is provided with through hole, and rocking bar 6 is through on the through hole, and operation rocking bar 6 just can easily be with moving sleeve 5 to rotate.
Certainly, according to actual needs, the quantity that is through the wedge 3 on the opening annulus 2 also can be two or more, as long as wedge 3 can form stepless action power to stud 1.And the quantity that is used for the annular retainer of stationary wedge piece 3 also can be one or more, and it is decided according to wedge quantity and actual location and support needs.
When the present embodiment when reality is used, at first that two opening annulus 2 are upper and lower horizontally, four wedges 3 are through on two opening annulus 2 simultaneously equably, and utilize alignment pin 7 that wedge 3 positions are fixed; Then, sleeve 5 is enclosed within four wedge 3 outsides, and is connected with the external screw thread that four wedges 3 form by internal thread 4; Follow again, after the inclined-plane of 5, four wedges 3 of turnbarrel and sleeve 5 further is connected, 2 contractions of opening annulus, four wedges 3 are drawn close to the inside simultaneously, and stop operating when close with stud diameter to be removed; At last, four wedges 3 and the assembly that sleeve 5 forms are enclosed within on the movable end lateral surface of stud 1 to be removed, utilize rocking bar 6 to continue turnbarrel 5 and tighten up wedge 3, the inboard arcwall face of wedge fully contacts with stud movable end surface, and final under the effect of frictional force with stud 1 chucking and unload, thereby finish the unloading process of whole stud 1.
Certainly, as carry out the installation of stud, then above-mentioned steps can realize equally, only should be noted that last direction of rotation gets final product.
