Abstract
The invention discloses a disassembly technology for remanufacturing a deformation hinge pin of a concrete pump truck. The disassembly technology comprises the following steps that (1) a hole is drilled in the axial center position of the deformation hinge pin and the diameter of the drilled hole is smaller than that of the hinge pin; (2) the method that a jack or a hammer is used for knocking the hinge pin wall after the hole is drilled is adopted, so that the deformation hinge pin is disassembled. When the diameter of the hinge pin is large, the hole is bored after being drilled, so that the hinge pin wall has a soft elastic structure after the hole is drilled. Under the condition that a shaft sleeve and a component body are not damaged, the reuse value of the shaft sleeve is achieved, the remanufacturing cost is effectively reduced, the procedures that the shaft sleeve is installed and welded again, a line is drawn, a shaft sleeve hole is machined are not needed, the production bottleneck is overcome, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to the concrete mixer field, particularly a kind of technique of disassembling of manufacturing again concrete mixer distortion bearing pin.
Background technology
Find when retired concrete mixer is manufactured that the part bearing pin is out of shape again, cause between axle and axle sleeve occurring disalignment, inconsistent phenomenon, as shown in accompanying drawing 1, accompanying drawing 2, Fig. 1 comprises axle sleeve 1 and bearing pin 2, place, Fig. 2 middle section (G point) dislocation distortion.When pump truck is manufactured again, the distortion bearing pin is difficult to remove, and axle and axle sleeve together need be cut off just and can disassemble.Damaged axle sleeve and member body while disassembling the distortion bearing pin, lost the recycle value of axle sleeve and member body, reduced parts recycling rate, made again manufacturing cost increase.The member body of damaging while disassembling is the assembly welding axle sleeve again, and postwelding needs machining shaft trepanning again, thereby has extended the production cycle, increased processing cost.As calculated and analyze, the residual life of axle sleeve is also very long, can meet next life cycle, if disassemble in process, does not damage axle sleeve, can directly recycle.
Summary of the invention
In order to solve the problems of the technologies described above, not damage axle sleeve and member body while the invention provides a kind of disassembling, disassemble the technique of disassembling of manufacturing again concrete mixer distortion bearing pin that efficiency is high.
The technical scheme that the present invention addresses the above problem is: a kind of technique of disassembling of manufacturing again concrete mixer distortion bearing pin comprises the following steps:
A kind of technique of disassembling of manufacturing again concrete mixer distortion bearing pin comprises the following steps:
(1) in the boring of distortion bearing pin axial centre place, bore diameter is less than pin diameter;
(2) mode that adopts jack or hammer to beat boring rear pin shaft wall, remove the distortion bearing pin.
In described step (1), bore hole again after distortion bearing pin axial drilling, make the bearing pin wall after boring that soft elastic construction be arranged.
Boring is less than the blind hole of bearing pin length for hole depth.
Boring is through hole.
Beneficial effect of the present invention is: the present invention is not in the situation that damage axle sleeve and member body has realized the recycle value of axle sleeve, effectively reduce manufacturing cost again, and do not need again the operations such as assembly welding axle sleeve, line, machining shaft trepanning, solved production bottleneck, production efficiency has improved more than 20%.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Embodiment mono-:
As shown in Figure 2, Figure 3, Figure 4, disassemble front at bearing pin 2 axial centre place drilling blind holes 3, bore diameter is less than bearing pin 2 diameter 3mm, bearing pin wall thickness 1.5mm after making to hole, the hole depth of blind hole 3 is less than bearing pin 2 length 10mm, bore hole after bearing pin 2 diameters can adopt boring when larger, make the bearing pin wall after processing that softer elastic construction be arranged; Then adopt the mode of beaing the bearing pin wall by supplemental support 4 and hammer 5, remove distortion bearing pin 2.
The method of drilling blind hole 3 is disassembled the distortion bearing pin, makes bearing pin 2 be processed into thin-wall construction, reduces bearing pin 2 rigidity, and while with hammer 5, by tapped or with jack, disassembling bearing pin 2, easily cave in the former dislocation of bearing pin 2 position, thereby realizes disassembling purpose.
Embodiment bis-:
As shown in Fig. 6, Fig. 7, Fig. 8, drill through hole 6 being out of shape bearing pin 2 axial centre places, bore diameter is less than bearing pin 2 diameter 4mm, makes the bearing pin wall thickness 2mm after boring, by supplemental support 4 and hammer 5, adopts the modes of beaing to be disassembled bearing pin 2.
The present invention is not in the situation that damage axle sleeve and member body has realized the recycle value of axle sleeve, effectively reduce manufacturing cost again, and do not need again the operations such as assembly welding axle sleeve, line, machining shaft trepanning, solved production bottleneck, make production efficiency improve more than 20%.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obvious realization of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical solution of the present invention to carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
