Abstract
The utility model relates to an apparatus for disassembling axle pin, in particular to a disassembling apparatus of wedge pin, comprising a cover plate, screws inserted in the cover plate and a plurality of jack screws connected with the screws of the cover plate in a threaded way. Wherein among the jack screws at least a flat connecting line of two jack screws passes through the screw. By the adoptive apparatus for disassembling axle pin, the labor intensity of workmen can be decreased, and when axle pin is dismantled, the disassembling space's restriction of the dismantling behavior is reduced, accordingly the dismantling of the axle pin is made to be more flexible.
Description
Technical field
The utility model relates to a kind of provision for disengagement of bearing pin, relates in particular to a kind of provision for disengagement of taper pin.
Background technology
Usually, when equipment is keeped in repair, dismantle, in unloading process, run into the situation that needs the dismounting bearing pin through regular meeting equipment.At present, in the process of dismounting bearing pin, generally all can use pendulum.
But because the weight of pendulum is bigger, carrying is effort very, and it is relatively poor to use flexibility, and it is also more loaded down with trivial details to operate; In addition, in the process of dismounting bearing pin, pendulum is used in inconvenience sometimes, such as the restriction that is subjected to the withdrawal space, perhaps when the bearing pin mouth be when upwards offering, just be not suitable for using pendulum.
Therefore, be necessary to design a kind of provision for disengagement of new bearing pin, to overcome above-mentioned various defectives.
The utility model content
The purpose of this utility model is to provide a kind of provision for disengagement of bearing pin, by using this provision for disengagement, can reduce working strength of workers, and the withdrawal space is dismantled the restriction of behavior to this when reducing the dismounting bearing pin, and makes to the bearing pin dismounting more flexible.
To achieve these goals, the utility model is design like this: the provision for disengagement of this bearing pin comprises a cover plate, is inserted in screw and a plurality of jackscrew that is threaded with cover plate in the cover plate, and the horizontal line that has two jackscrews in the wherein said jackscrew at least is by described screw.
By adopting the provision for disengagement of above-mentioned bearing pin, can reduce working strength of workers, the withdrawal space is dismantled the restriction of behavior to this when reducing the dismounting bearing pin, and makes that the bearing pin dismounting is more flexible, thereby saves the take-down time, increases work efficiency.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the cutaway view of provision for disengagement when the dismounting bearing pin of bearing pin of the present utility model.
The specific embodiment
See also Fig. 1, the provision for disengagement 1 of the bearing pin shown in Fig. 1 is used to dismantle bearing pin 40, especially dismounting bearing pin 40 under dismounting required precision condition with higher.
This provision for disengagement 1 comprises a cover plate 30, this cover plate 30 is preferably made by the higher sheet metal of intensity, center position at cover plate 30 plugs a screw 20, the nut 200 of this screw 20 is fastened in the first surface 300 of described cover plate 30, then overhang out the second surface 302 of cover plate 30 of the screwed screw rod 202 of screw 20, this second surface 302 combines with the face of pulling pin 500 of body 50, under dismounting required precision condition with higher, needs to guarantee the Surface Machining precision of second surface 302.
Around cover plate 30, be provided with the identical screw of a plurality of specifications 304, in each screw 304, all screwed in jackscrew 10 with its coupling, the diameter of these jackscrews 10 and pitch are all identical, and the line that has a pair of jackscrew 10 in these jackscrews 10 at least is through screw 20, described jackscrew 10 is made by wear-resisting high-strength metal material, like this, can reduce to cause that because of moving repeatedly wearing and tearing cause the decline of its precision.In addition, when the adhesion between bearing pin 40 and body 50 is big, then a plurality of jackscrews 10 need be installed around cover plate 30, thereby when these jackscrew 10 turns simultaneously, can provide enough pulling capacities bearing pin 40.
When dismantlement work is carried out in this provision for disengagement 1 of application, at first the screw rod 202 of screw 20 is passed the centre bore 306 of cover plate 30 and be selected into the default screw (not label) of bearing pin 40, then jackscrew 10 is screwed in screws 304 and the butt face 500 of pulling pin, the jackscrew of precession simultaneously 10 then, make cover plate 30 rise, move upward, and then make bearing pin 40 be subjected to upwards drawing effect thereby drive screw 20 along jackscrew 10, like this, bearing pin 40 just withdraws from from body 50 gradually.
Usually, though the jackscrew 10 of precession simultaneously may be different by the pitch of precession, when the difference of the pitch of precession than hour, bearing pin 40 can be withdrawed from smoothly.
When but thin or material is more crisp when the diameter of axle of bearing pin 40, the difference of jackscrew 10 precession pitch may cause screw 20 because of being subjected to the moment of flexure effect plastic deformation takes place even fractureing, if plastic deformation takes place in bearing pin 40, adhesion between bearing pin 40 and the body 50 is increased, perhaps destroy the joint portion of body 50 and bearing pin 40; If bearing pin 40 fractures, then can increase the difficulty of dismantlement work in body 50.In this case, can use existing interlock spanner (not shown), the angle of using this spanner can guarantee that each jackscrew 10 is rotated at every turn is identical, thereby guarantees that precession pitch is identical, therefore can effectively avoid bearing pin 40 because of being subjected to the various consequences that the moment of flexure effect causes.
By adopting the provision for disengagement of above-mentioned bearing pin, can reduce working strength of workers, the withdrawal space is dismantled the restriction of behavior to this when reducing the dismounting bearing pin, and makes that the bearing pin dismounting is more flexible.
