Description
Technical field
The utility model is related to the boring processing molds of bearing shell.
Background technology
Bearing shell is the part of sliding bearing and journal contact, and shape is the semi-cylindrical of tiles, unusual light, bush material
Usual softer, inner cylinder face（Bearing shell inner wall）It should not be processed with filing, boring, Buddha's warrior attendant boring, scraping or grinding may be employed
Method is processed.
The boring processing mold of bearing shell is common bearing shell processing mold, and existing bearing shell boring processing mould, which generally comprises, to be used for
The bearing shell placing groove of bearing shell is placed, the inner wall of bearing shell placing groove is semi-cylindrical, and bearing shell is fixed in bearing shell placing groove, bearing shell
The inner wall of outer wall and bearing shell placing groove reclines, and can carry out boring processing to the inner wall of bearing shell.
But the bearing shell that existing bearing shell boring processing mold is processed, wall thickness is single, i.e., half bearing thickness is axially protected along bearing shell
It holds unanimously, bearing shell is used with axle journal assembling, easily generates eccentric wear.
Initial stage break-in is adapted in order to avoid eccentric wear and quickly, the wall thickness of bearing shell will be handled especially, make half bearing thickness along axis
To gradual change, bearing shell axial direction thick middle, axial both ends are thin, and carrying is uniform when such bearing shell works, and can effectively avoid eccentric wear, and can be more
It is suitble to initial stage break-in soon.
Therefore new bearing shell boring processing mold is needed, in bearing shell right boring bearing shell is made to be deformed vertically.
Utility model content
The purpose of this utility model is to provide a kind of boring processing molds of bearing shell, can produce wall thickness and become vertically
The bearing shell of change.
To achieve the above object, the technical solution of the utility model is to design a kind of boring processing mold of bearing shell, including
Die main body, die main body are equipped with to place the bearing shell placing groove of bearing shell, and bearing shell placing groove is straight slot, and bearing shell placing groove
Inner wall is semi-cylindrical；
Using the edge at bearing shell placing groove inner wall axial direction both ends as inner wall end edge；
The inner wall end edge at bearing shell placing groove axial direction both ends each extends over the semi-circular shape convex edge of convex, and convex edge is put with bearing shell
Put the coaxial heart of slot；
The axial both ends of convex edge are respectively：The bigger diameter end that maintains an equal level with corresponding inner wall end edge and opposite with bigger diameter end small
Footpath end；
The internal diameter of convex edge is gradually increased by miner diameter end to bigger diameter end.
Preferably, through hole, through hole axle center and the axis perpendicular of bearing shell placing groove inner wall are additionally provided on bearing shell placing groove inner wall；
Through hole is located at the axial middle part of bearing shell placing groove, and through hole is located at the circumferential middle part of bearing shell placing groove inner wall.
Preferably, the convex edge at bearing shell placing groove axial direction both ends is symmetrical arranged with through hole.
The advantages of the utility model and advantageous effect are：A kind of boring processing mold of bearing shell is provided, can be produced
The axially varying bearing shell of wall thickness.
Bearing shell to be processed is fixed in bearing shell placing groove, and bearing shell is set in the same direction with bearing shell placing groove, the outer wall of bearing shell with
The convex edge at bearing shell placing groove axial direction both ends reclines, and in bearing shell right boring, the convex edge at bearing shell placing groove axial direction both ends can produce bearing shell
Change shape, produces the axially varying bearing shell of wall thickness, and such bearing shell can prevent unbalance loading, and initial stage can be quickly suitble to grind
It closes.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：
As shown in Figure 1, a kind of boring processing mold of bearing shell, including die main body 1, die main body 1 is equipped with to place
The bearing shell placing groove 2 of bearing shell, bearing shell placing groove 2 is straight slot, and the inner wall of bearing shell placing groove 2 is semi-cylindrical；
Using the edge at 2 inner wall axial direction both ends of bearing shell placing groove as inner wall end edge；
The inner wall end edge at the axial both ends of bearing shell placing groove 2 each extends over the semi-circular shape convex edge 3 of convex, convex edge 3 and axis
Watt 2 coaxial heart of placing groove；
The axial both ends of convex edge 3 are respectively：The bigger diameter end that maintains an equal level with corresponding inner wall end edge and opposite with bigger diameter end small
Footpath end；
The internal diameter of convex edge 3 is gradually increased by miner diameter end to bigger diameter end.
Through hole 4,4 axle center of through hole and the axis perpendicular of 2 inner wall of bearing shell placing groove are additionally provided on 2 inner wall of bearing shell placing groove；It is logical
Hole 4 is located at the axial middle part of bearing shell placing groove 2, and through hole 4 is located at the circumferential middle part of 2 inner wall of bearing shell placing groove.
The convex edge 3 at the axial both ends of bearing shell placing groove 2 is symmetrical arranged with through hole 4.
The boring processing mold of the utility model bearing shell can produce the axially varying bearing shell of wall thickness.
Bearing shell to be processed is fixed in bearing shell placing groove 2, and bearing shell is set in the same direction with bearing shell placing groove 2, the outer wall of bearing shell
It reclines with the convex edge 3 at the axial both ends of bearing shell placing groove 2, in bearing shell right boring, the convex edge 3 at the axial both ends of bearing shell placing groove 2 can make
Bearing shell is deformed, and produces the axially varying bearing shell of wall thickness, and such bearing shell can prevent unbalance loading, and can be quickly suitble to just
Phase break-in.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
