Background technology
Connecting rod is the stressed movement parts of connecting engine piston, in cylinder, under reciprocating motion effect, should possess enough intensity, therefore be bumped into that lining in connecting rod must keep reliable operation and durable, can say that in some sense lining is the harshest bearing in machine driving.In supercharged diesel engine, mostly configure inclined cutout connecting rod, the two ends of connecting rod are the structure of large and small circular hole relatively, and lining need be pressed into the roundlet nose end of connecting rod.Its craft precision that is pressed into of inclined cutout connecting rob bushing requires very high, most critical be that lining must vertically must not be pressed into a little deflection to gonnecting rod body, and the oilhole of lining also must align with the oilhole of connecting rod, be inaccurately easy to cause lining press partially and cause connecting rod to be scrapped if located.A kind of connecting rob bushing press-in device the utility model proposes, can make this problem be satisfactorily resolved.
Summary of the invention
The purpose of this utility model is, a kind of inclined cutout connecting rob bushing press-in device with automatic positioning function is provided, and can guarantee that oblique lining is accurately pressed in connecting rod circular hole.
For realizing the technical scheme that the utility model object adopts be: pressure head penetrates gland assembly, and pressure head and gland assembly are fixed by jackscrew, and pressure head and principal axis of pressing machine are connected and fixed.The angle of inclination on inclined-plane, gland assembly lower end is consistent with the angle of inclination of connecting rob bushing end face, the lower end of lathe pressure head penetrates positioner, positioner is provided with a steel ball being supported by stage clip, the oilhole centering location in steel ball and lining, and the bottom of stage clip is provided with plug.Gland package count millimeter is inserted in the upper end of positioner, and connecting rob bushing is inserted in positioner.Form fixture by locating shaft, positioning sleeve, the angle of inclination on inclined-plane, positioning sleeve upper end is consistent with the angle of inclination of connecting rob bushing lower surface.Spring is housed in positioning sleeve, and locating shaft is placed on spring, and the roundlet nose end of connecting rod inserts location number of axle millimeter, and forcing press drives and moves down with the pressure head of lining, is pressed in connecting rod small sircle hole complete lining.
Bush press-in device, by after forcing press equipment adjustment centering, is realized the gland technique of inclined cutout connecting rod.By the oilhole centering location in steel ball and lining in positioner, now the inclined-plane of gland and the bevel angle of lining are consistent, guarantee not destroy while being pressed into thus the quality of connecting rob bushing.
Feature of the present utility model and beneficial effect are: by positioning sleeve and steel ball location, guarantee that angle and the lining bevel angle of bushing oil hole is consistent with connecting rod, lining is pressed in small end of connecting rod circular hole accurately according to the angle of design.This device cost of manufacture is low, simple to operate and be easy to adjustment, has solved inclined cutout connecting rob bushing and has been pressed into rear two hypotenuse height inconsistence problems, has guaranteed that connecting rod quality has reduced processing cost.

The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is described further.
The inclined cutout connecting rob bushing press-in device with automatic positioning function, comprises pressure head, gland assembly, positioner, connecting rob bushing, connecting rod, locating shaft, positioning sleeve, spring, jackscrew, steel ball, stage clip, plug and detection cover etc.Its structure is: pressure head 1 penetrates gland assembly 2, pressure head and gland assembly are fixing by jackscrew 5, pressure head and principal axis of pressing machine are connected and fixed, and the angle of inclination on inclined-plane, gland assembly lower end is consistent with the angle of inclination of connecting rob bushing 4 end faces, and the lower end of lathe pressure head penetrates positioner 3(as Fig. 1 Fig. 2).Positioner is provided with a steel ball being supported by stage clip 67, the oilhole centering location in steel ball and lining, the bottom of stage clip is provided with plug 8(as Fig. 3).5 millimeters of gland assemblies are inserted in the upper end of positioner, and connecting rob bushing is enclosed within outside positioner, forms fixture by locating shaft 9, positioning sleeve 10, and the angle of inclination on inclined-plane, positioning sleeve upper end is consistent with the angle of inclination of connecting rob bushing lower surface.Spring 11 is housed in positioning sleeve, and locating shaft is placed on spring, and the roundlet nose end of connecting rod 12 inserts 5 millimeters of locating shafts, and forcing press drives the pressure head that connecting rob bushing is housed to move down, and is pressed in connecting rod small sircle hole complete connecting rob bushing.Fixture is placed on the workbench of forcing press, and the center of fixture center line and press ram is overlapped 13 verifications by a dedicated test and aligned.
For guaranteeing the centering of pressure head part and holder part, specialized designs detect and overlap (see figure 4).After pressure head part and holder part fix, detect two-part centering with detecting cover, can not pack into smoothly in pressure head and locating shaft if detect cover, readjust pressing sleeve device, guarantee two-part centering, thereby guarantee that lining is pressed in gonnecting rod body smoothly.
Fixture assembly is on the workbench of forcing press, and while being pressed into lining, small end of connecting rod is contained on locating shaft, and the position of connecting rod is fixed, and the angle of positioning sleeve is consistent with the angle of small end of connecting rod, fixing after adjusting angle in when assembling.The work of starting pressure lathe, moves down along with pressure head withstands lining, and under the effect of ram pressures, locating shaft moves down in positioning sleeve, until lining is all pressed in connecting rod.The diameter of gland assembly inner sleeve is identical with connecting rob bushing external diameter, and when work, gland assembly withstands lining and is pressed in gonnecting rod body, as long as guarantee that the angle of inner sleeve is consistent with gonnecting rod body, this structure has good processing technology during fabrication.
As embodiment: the utility model uses on 4102H serial diesel engine connecting rob bushing assembly line, specific operation process: 4102H.04.10 small end of connecting rod circular hole is of a size of to φ 38 and inserts in locating shaft, now guarantee that connecting rod and positioning sleeve fit tightly, then connecting rob bushing is inserted in pressure head, in connecting rob bushing, hole dimension is φ 35, and connecting rob bushing excircle dimension is φ 38.In the process of insertion pressure head, the oilhole automatic and lining under the effect of spring force of the steel ball in positioner is located, and now the inclined-plane of connecting rob bushing is consistent with the angle of gland assembly.Now operating pressure cleaner handgrip, is pressed into the lining on pressure head in connecting rod small end hole, in the time that the inclined-plane of gland assembly and inclined surface of connecting rod fit together, represents that gland completes.
