Description
Technical field
The utility model relates to oil sealing load module, is specifically related to a kind of gatherer of engine crankshaft rear oil seal.
Background technology
Crankshaft rear oil seal, as the parts of in engine, mainly plays sealing, once the state appearance such as postal scuffing in assembling process, will have a strong impact on the performance of engine.Crankshaft rear oil seal is as the procedure on wiring in engine line, due to the reason such as shape and production line cost of investment of itself, on assembly line below 300,000/annual capacity, seldom can install with equipment, usually all can adopt manual station to assemble.On diesel engine of passenger car assembly line, crankshaft rear oil seal needs first to carry out gluing to sealing surface, is then assembled on engine, directly utilize manual installation, not only poor accuracy, inefficiency, and destructible adhesive tape and scuffing crankshaft rear oil seal inner surface, cause seal failure.
Comprehensive foregoing description:
1, Rear oil seal structural particularity, requires that Rear oil seal gatherer positioning precision wants high, otherwise causes lip major injury.
2, the material of Rear oil seal gatherer is most important, then oil seal lip is generally made up of elastomeric material, many employing 45 steel, nylon, elastomeric material in the market, such as material adopts nylon, through lathe process and grinding machine reconditioning, Rear oil seal gatherer roughness of excircle is very high, will cause Rear oil seal lip major injury; Adopt 45 steel then too heavy; If material is rubber, frictional force is comparatively large, and Rear oil seal is difficult to push.
Therefore, a kind of quick assembly tool accurately has very large meaning to the efficiency and assembly quality that promote assembly line.
Utility model content
Problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of fast accurate to install the gatherer of engine crankshaft rear oil seal.
For solving the problem, the technical solution adopted in the utility model is: a kind of gatherer of engine crankshaft rear oil seal, comprises handle, also comprises fairlead, locating dowel and lip limit; Described fairlead is connected with handle, and described lip limit is coated on fairlead front end; Described locating dowel is positioned in the middle part of fairlead, is the cylinder of a protrusion.
The thickness on described lip limit is outwards thinning gradually by fairlead end.And described lip limit is engaged completely with crankshaft rear end cylindrical.
Described locating dowel coordinates with crankshaft installed interporal lacuna.
The surface of described fairlead adopts polytetrafluoroethylene (PTFE) to make.
Described handle surfaces has annular knurl striped.
Action principle of the present utility model is: be enclosed within by engine crankshaft rear oil seal on the fairlead of gatherer, bearing mounting hole is inserted by locating dowel, and lip limit is engaged in crankshaft rear end cylindrical, then engine crankshaft rear oil seal is arranged on bent axle to extrapolation gradually.
Compared with prior art, the beneficial effect that the utility model realizes is:
1, described lip limit is coated on fairlead front end, closely can be engaged, play good fixation with crankshaft rear end cylindrical, avoids occurring sliding, and causes Rear oil seal to occur installation deviation.
2, the thickness on lip limit is outwards thinning gradually by fairlead end, can ensure Rear oil seal transition gradually like this, steadily slide on bent axle.
3, described locating dowel coordinates with crankshaft installed interporal lacuna, ensures accurate positioning, locating dowel and machining crankshaft bearing borehole and bearing mounting hole Dual positioning, more precisely.
4, the surface of fairlead adopts polytetrafluoroethylene (PTFE) to make.Polytetrafluoroethylmaterial material very soft tender, smooth, friction factor is lower, Ra1.6 is reached by the outer surface roughness after lathe process, during built-up crankshaft Rear oil seal assembly, Rear oil seal gatherer is very little to the damage of Rear oil seal lip, can not cause engine oil leakage phenomenon.
5, handle surfaces has annular knurl striped, can be anti-skidding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model coordinates schematic diagram with engine crankshaft.
Mark in figure:
1, handle; 2, fairlead; 3, locating dowel; 4, lip limit.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further:
A gatherer for engine crankshaft rear oil seal, comprises handle 1, also comprises fairlead 2, locating dowel 3 and lip limit 4; Described fairlead 2 is connected with handle 1, and described lip limit 4 is coated on fairlead 2 front end; Described locating dowel 3 is positioned in the middle part of fairlead 2, is the cylinder of a protrusion.
The thickness on lip limit 4 is outwards thinning gradually by fairlead 2 end.And described lip limit 4 is engaged completely with crankshaft rear end cylindrical.Described locating dowel 3 coordinates with crankshaft installed interporal lacuna.The surface of fairlead 2 adopts polytetrafluoroethylene (PTFE) to make.There is annular knurl striped on handle 1 surface.
Action principle of the present utility model is: be enclosed within by engine crankshaft rear oil seal on the fairlead 2 of gatherer, bearing mounting hole is inserted by locating dowel 3, and lip limit 4 is engaged in crankshaft rear end cylindrical, then engine crankshaft rear oil seal is arranged on bent axle to extrapolation gradually.
Compared with prior art, the beneficial effect that the utility model realizes is: described lip limit 4 is coated on fairlead 2 front end, closely can be engaged, play good fixation with crankshaft rear end cylindrical, avoids occurring sliding, and causes Rear oil seal to occur installation deviation.The thickness on lip limit 4 is outwards thinning gradually by fairlead 2 end, can ensure Rear oil seal transition gradually like this, steadily slide on bent axle.Locating dowel 3 coordinates with crankshaft installed interporal lacuna, ensures accurate positioning, locating dowel 3 and machining crankshaft bearing borehole and bearing mounting hole Dual positioning, more precisely.The surface of fairlead 2 adopts polytetrafluoroethylene (PTFE) to make.Polytetrafluoroethylmaterial material very soft tender, smooth, friction factor is lower, Ra1.6 is reached by the outer surface roughness after lathe process, during built-up crankshaft Rear oil seal assembly, Rear oil seal gatherer is very little to the damage of Rear oil seal lip, can not cause engine oil leakage phenomenon.There is annular knurl striped on handle 1 surface, can be anti-skidding.
The above is only preferred embodiment of the present utility model, is not restriction the utility model being made to other form.Any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to structure of the present utility model and operation principle, still belong to the protection domain of technical solutions of the utility model.
