Summary of the invention
For the prior art deficiency, technical problem to be solved by this invention is to provide pipe fitting pressed labor outfit and pressing method on a kind of engine, low to reach equipment cost, the purpose that press-fitting tool is difficult for breaking down.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Pipe fitting pressed labor outfit on a kind of engine, comprise pressure head and guide plate, described guide plate is provided with alignment pin, described pressure head slides and is located in the gathering sill of guide plate, be provided with and block the draw-in groove that pipe fitting is used in the pressure head end of described guide plate one side, be provided with the spacer pin stretched out on the pressure head of described guide plate opposite side.
Further, described pressure head be provided with gathering sill in the suitable spigot surface of slip plane.
The draw-in groove of described pressure head end is " U " type groove.
Described alignment pin is two, respectively with engine on locating hole suitable.
On described pressure head, the end face of draw-in groove opposite end is plane, and is provided with bulge loop in this pressure head end.
The end face that described pressure head is provided with draw-in groove one end is plane.
A kind of pressing method that utilizes pipe fitting pressed labor outfit on engine described above, its pressing method comprises the following steps:
1) first the alignment pin on guide plate is coordinated with the locating hole on engine body, guide plate is fixed on engine body;
2) get the installing hole place that pipe fitting is put into engine body, the draw-in groove of pressure head is stuck on pipe fitting, and the gathering sill guiding that makes pressure head pass through guide plate compresses pipe fitting;
3) the pressure head upper end that pounds with a hammer, when spacer pin contacts with guide plate, stop knocking;
4) take off frock, pipe fitting is press-fit into place.
The present invention compared with prior art, has the following advantages: tool structure is simple, easy to use, and reliability is high; Can guarantee the assembly quality of high request, equipment cost is low; Press-fitting tool is difficult for breaking down in assembling process, long service life.
The accompanying drawing explanation
Below to each width accompanying drawing of this specification, expressed content and the mark in figure are briefly described:
Fig. 1 is that frock of the present invention press-fits the hot air hose schematic diagram.
Fig. 2 is pressure head structure schematic diagram of the present invention.
In figure: 1. pressure head, 11. draw-in grooves, 12. spigot surfaces, 13. limit pin holes, 14. bulge loops, 2. spacer pin, 3. guide plate I, 4. guide plate II, 5. bolt I, 6. bolt II, 7. alignment pin I, 8. alignment pin II, 9. hot air hose, 10. cylinder cap.
The specific embodiment
Below contrast accompanying drawing, the description by embodiment, be described in further detail the specific embodiment of the present invention.
As depicted in figs. 1 and 2, pipe fitting pressed labor outfit on engine, its pipe fitting is the hot air hose 9 be connected with cylinder cap 10, and this frock comprises pressure head 1 and guide plate, and pressure head 1 is cylindrical structure; Guide plate is guide plate I 3 and the guide plate II 4 that shape equally is superimposed, guide plate I 3 is with together with guide plate II 4 is bolted on, be fixedly installed alignment pin I 7 by bolt I 5 on guide plate II 4, be fixedly installed alignment pin II 8 by bolt II 6 on guide plate II 4, on alignment pin I and cylinder cap, locating hole is suitable, and the spark-plug hole on alignment pin II and cylinder cap is suitable; Guide plate is provided with gathering sill, pressure head 1 slides and is located in the gathering sill of guide plate, and be provided with and block the draw-in groove 11 that pipe fitting is used in the pressure head end of guide plate one side, be provided with the spacer pin 2 stretched out on the pressure head of guide plate opposite side, spacer pin 2 interference fit are located in the cylindrical limit pin hole 13 of pressure head, by spacer pin, limit the hot air hose compression distance.
The draw-in groove 11 of pressure head 1 end is " U " type groove, and the openings of sizes of draw-in groove 11 is consistent with the external diameter of hot air hose, just in time blocks hot air hose.
On pressure head 1, the end face of draw-in groove opposite end is plane, is convenient to knock press-fited operation; And be provided with bulge loop 14 in this pressure head end, prevent from skidding off other parts of damage when knocking.The end face that pressure head is provided with draw-in groove one end is plane, can block the flange of the mouth of pipe of hot air hose, guarantees to press-fit the stability of operation.
Utilize this frock to press-fit the pressing method of the hot air hose on cylinder cap, comprise the following steps:
1) first locating hole, spark-plug hole on the cylinder cap of two alignment pins on guide plate and engine are matched, the guide plate location is fixed on cylinder cap;
2) the heating airduct is put into the installing hole place of cylinder cap, utilizes the draw-in groove of pressure head to be stuck on hot air hose, and the gathering sill guiding that makes pressure head pass through guide plate compresses hot air hose;
3) knock the pressure head upper end with "painted-face" character in opera, pressure head moves down hot air hose is fitted on the installing hole of cylinder cap, when spacer pin contacts with guide plate, stops knocking;
4) take off frock, hot air hose is press-fit into place.
In press-fiting process, spigot surface has limited the angle that hot air hose press-fits, spacer pin has limited the degree of depth that press-fits of hot air hose, utilize this frock to replace high assembly precision and rely on the present situation that numerical control device completes, adopt assembling manually can realize the press-loading process requirement, equipment cost is low, and press-fitting tool is difficult for breaking down, long service life.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
