Abstract
The utility model provides a mounting and dismounting device for a bushing, mainly composed of a press cover, a chassis, a double-head threaded screw, a front nut and a rear nut. The connecting position of the inner end surface of the press cover and an outer cylinder surface is provided with a circular arc chamfering matched with the circular arc surface of the bushing; the chassis is mainly composed of a chassis seat, a movable position disc and a reset spring; the outer diameter of the movable position disc is matched with the inner diameter of a mounting hole of the bushing. The mounting and dismounting device for a bushing can be used to conveniently mount and dismount a main bushing on a diesel engine.
Description
The utility model relates to a kind of dismantling device in the diesel engine repairing, relates in particular to the dismantling device of diesel engine main bearing shell.
When repairing diesel engine, the dress main bearing shell is the operation that beats one's brains, and, a brand-new main bearing shell is beaten into scar scrap again and again because of careless through regular meeting.
The purpose of this utility model provides a kind of instrument that can easily main bearing shell be installed on the diesel-engine body.
Technical solution of the present utility model to achieve these goals is such: the bearing shell tool for fastening/disengaging is mainly by gland, the chassis, double threaded screw, preceding nut, back nut is formed, gland and chassis all are processed with center through hole, double threaded screw can pass the center through hole on gland and chassis, preceding nut and back nut can be installed in the two ends of double threaded screw, wherein the intersection of the inner face of gland and external cylindrical surface is processed with circular arc chamfering, the arc surface of this circular arc chamfering and bearing shell matches, the chassis is mainly by subbase, the activity orientation dish, back-moving spring is formed, and the internal diameter of the external diameter of activity orientation dish and bearing shell installing hole matches.
Tear bearing shell for convenience open, the position near the outer face on the external cylindrical surface of foregoing gland is processed with the contraction step, shrink the external diameter of step and the internal orifice dimension of bearing shell and match, the diameter of the external cylindrical surface of gland is less than the internal diameter of body top bearing shell installing hole.
Because in the above-mentioned technical solution, the external diameter of the activity orientation dish on chassis and the internal diameter of bearing shell installing hole match, the circular arc chamfering of the intersection of gland inner face and external cylindrical surface and the arc surface of bearing shell match, the circular arc chamfering that is pasting a side, the gland of the bearing shell installing hole of body when the chassis pasting the arc surface of bearing shell from the opposite side of the bearing shell installing hole of body, under the effect of double threaded screw and front and back nut, bearing shell is steadily compressed into the bearing shell installing hole of body; When will be when body be pulled down with bearing shell, bearing shell is aimed at not with an end of arc surface in the outer face of gland, the contraction step of gland just in time inserts the bearing shell endoporus, and the contraction end face that shrinks step heads on the end face of bearing shell, beats gland with iron hammer and can pull down bearing shell easily; Therefore the utility model can install to main bearing shell on the diesel-engine body easily and reliably, and also can easily main bearing shell be pulled down.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the schematic diagram with bearing shell tool for fastening/disengaging dress bearing shell.
Fig. 2 is for tearing the schematic diagram of bearing shell open with the bearing shell tool for fastening/disengaging.
Wherein: 1, preceding nut; 2, gland; 3, bearing shell; 4, body; 5, chassis; 6, back nut; 7, double threaded screw; 8, subbase; 9, activity orientation dish; 10, connect rivet; 11, back-moving spring; 12, iron hammer.
As shown in Figure 1, the bearing shell tool for fastening/disengaging is made of gland 2, chassis 5, double threaded screw 7, preceding nut 1, back nut 6; Chassis 5 is made up of subbase 8, activity orientation dish 9, connection rivet 10, back-moving spring 11, and the internal diameter of the external diameter of activity orientation dish 9 and body 4 top bearing shell installing holes matches; The inner face of gland 2 and the intersection of external cylindrical surface are processed with circular arc chamfering, the arc surface of this circular arc chamfering and bearing shell 3 matches, position near the outer face on the external cylindrical surface of gland 2 is processed with the contraction step, shrink the external diameter of step and the internal orifice dimension of bearing shell 3 and match, the diameter of the external cylindrical surface of gland 2 is less than the internal diameter of body 4 top bearing shell installing holes.
When wanting the installation shaft watt-hour, as shown in Figure 1, chassis 5 is being pasted body 4 the bearing shell installing hole a side and the external cylindrical surface of activity orientation dish 9 is just in time inserted in the bearing shell installing hole of body 4, the circular arc chamfering of gland 2 pasting the arc surface of bearing shell 3 from the opposite side of the bearing shell installing hole of body 4, under the acting in conjunction of double threaded screw 7 and preceding nut 1 back nut 2, bearing shell 3 is steadily compressed into the bearing shell installing hole of body 4.
In the time bearing shell will being pulled down, as shown in Figure 2, bearing shell 3 is aimed at not with an end of arc surface in the outer face of gland 2, make the contraction step of gland 2 just in time insert bearing shell 3 endoporus, the contraction end face that shrinks step heads on the end face of bearing shell 3, beats gland 2 with iron hammer 12 and can easily bearing shell 3 be pounded out, pull down.
