Description
Technical field
The utility model relates to a kind of connector element, especially a kind of stationary spindle, particularly a kind of easily detachable combined type stationary spindle.
Background technique
Stationary spindle linkage structure is modal a kind of structure in engineering, such as, hydraulic jumbo drill boom assembly with underframe, all adopt stationary spindle to be connected between hydraulic jack with drill boom.
Stationary spindle (during work, axle is not rotated) only carries the various power that rotary member passes over, so stationary spindle and fixed structure piece want interference fit, and can get rusty in stationary spindle joint (particularly engineering machinery), so just cause stationary spindle to dismantle cumbersome, and need the space of dismounting larger; Magnitude of interference when also having stationary spindle to install can not regulate.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of easily detachable combined type stationary spindle, and it is convenient to dismounting, less, the adjustable magnitude of interference of required installing space, can meet the general requirement of whole organization distribution concision and compact.
The technological scheme that the utility model adopts is as follows:
A kind of easily detachable combined type stationary spindle, comprise connecting bolt, described connecting bolt outer cover is connected to stationary axle, stationary axle two ends are provided with expansion cap, described expansion cap inwall is the conical surface, and the cone match outside described expansion cap inwall and stationary axle two end part, described expansion cap is provided with dilatation joint, the end tab that the expansion cap of described connecting bolt one end is connected bolt divides spacing, and the expansion cap arranged outside of the other end of described connecting bolt has nut.
Spring washer is provided with between nut and expansion cap.
Expansion cap is provided with tapped hole.
The beneficial effect that the technological scheme that the utility model provides is brought is:
Easily detachable combined type stationary spindle of the present utility model in use, if be connected and fixed axle place not have extremely, do not get rusty, so loosen nut, after external force unloading, the endogenetic process of expansion cap impels it to move outward, thus reaches expansion cap and separate with stationary axle, expansion cap reduced diameter, so become Spielpassung with coordinating of fixed component from interference fit, thus the object of separating both easily realizing.
If be connected and fixed axle place because to get rusty or other reasons causes and unclamps connecting bolt, expansion cap difficulty tear open situation time, at this moment need to unload nut, spring washer and connecting bolt, be screwed into the tapped hole on expansion cap with bolt, bolt withstands on stationary axle end face, thus expansion cap is moved outward, expansion cap separates with stationary axle, expansion cap reduced diameter, so becomes Spielpassung with coordinating of fixed component from interference fit, and then the object of separating both realizing.
In sum, the utility model can realize the combination of fixed component and rotary member easily and separate, under avoiding prior art, because getting rusty or enter foreign material in stationary spindle and fixed component junction, and be difficult to the problem of dismounting, adopt this structure to deal with problems well at some special position of engineering machinery.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of easily detachable combined type stationary spindle of the present utility model;
Fig. 2 is the expansion cap structural representation of easily detachable combined type stationary spindle of the present utility model;
Fig. 3 is the using state figure of easily detachable combined type stationary spindle of the present utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment one
A kind of easily detachable combined type stationary spindle, comprise connecting bolt 1, described connecting bolt 1 outer cover is connected to stationary axle 2, stationary axle 2 two ends are provided with expansion cap 3, described expansion cap 3 inwall is the conical surface, cone match outside described expansion cap 3 inwall and stationary axle 2 two end part, described expansion cap 3 is provided with dilatation joint 4, the end tab that the expansion cap of described connecting bolt 1 one end is connected bolt 1 divides spacing, and the expansion cap arranged outside of the other end of described connecting bolt 1 has nut 5.
Spring washer 6 is provided with between nut 5 and expansion cap 3.
Expansion cap 3 is provided with tapped hole 7.
As shown in Figure 1, this easily detachable combined type stationary spindle is made up of expansion cap 3, stationary axle 2, connecting bolt 1, spring washer 6, nut 5;
As shown in Figure 2, expansion cap 3 inwall has the taper fit at tapering and stationary axle 2 two ends, end face has tapped hole 7 so that tear expansion cap 3 open with bolt, face is opened a seam 4 to expand outward.
Expansion cap 3 and fixed component 8 Spielpassung during installation, by tightening nuts 5, stationary axle 2 male cone (strobilus masculinus) forces expansion cap 3 to expand outward, thus the coordinating from Spielpassung to interference fit of expansion cap 3 and fixed component 8, screwing force larger expansion cap swell increment is larger, thus reaches the effect regulating magnitude of interference.
During dismounting, if be connected and fixed axle 2 place not have extremely, do not get rusty, so loosen nut 5, after external force unloading, the endogenetic process of expansion cap 3 impels it to move outward, thus reach expansion cap 3 and separate with stationary axle 2, expansion cap 3 reduced diameter, so becomes Spielpassung with coordinating of fixed component 8 from interference fit.
If be connected and fixed axle 2 place because of get rusty or other reasons cause unclamp situation that connecting bolt 1 expansion cap 3 difficulty tears open time, at this moment need to unload nut 5, spring washer 6 and connecting bolt 1, the tapped hole 7 on expansion cap 3 is screwed into bolt, bolt withstands on stationary axle 2 end face, thus expansion cap 3 is moved outward, expansion cap 3 separates with stationary axle 2, and expansion cap 3 reduced diameter, so becomes Spielpassung with coordinating of fixed component 8 from interference fit.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
