As cylinder cap assembly line press-fited press-fiting of hot air hose on spark plug boot and cylinder cap, existing be mostly completed by baroque numerical control device to press-fit, though can product assembly quality be ensured, but it is large to there is equipment investment, maintenance cost is high, and maintenance time of breaking down is long, affects the deficiency that production line runs.
Summary of the invention
Not enough for prior art, 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 object that press-fitting tool not easily breaks 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 in the pressure head end of described guide plate side the draw-in groove blocking pipe fitting, the pressure head of described guide plate opposite side is provided with the spacer pin stretched out.
Further, described pressure head is provided with the spigot surface suitable with the slip plane in gathering sill.
The draw-in groove of described pressure head end is " U " type groove.
Described alignment pin is two, suitable with the locating hole on engine respectively.
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.
Utilize a pressing method for 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, make guide plate be fixed on engine body;
2) get the installing hole place that engine body put into by pipe fitting, the draw-in groove of pressure head is stuck on pipe fitting, makes pressure head compress pipe fitting by the gathering sill guiding of guide plate;
3) pound with a hammer pressure head upper end, when spacer pin contacts with guide plate, stops 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, and easy to use, reliability is high; Can ensure the assembly quality of high request, equipment cost is low; Press-fitting tool not easily breaks down in assembling process, long service life.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is that frock of the present invention press-fits 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.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
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 the guide plate I 3 that is equally superimposed of shape and guide plate II 4, together with guide plate I 3 is bolted on guide plate II 4, guide plate II 4 is fixedly installed alignment pin I 7 by bolt I 5, guide plate II 4 is fixedly installed alignment pin II 8 by bolt II 6, alignment pin I is suitable with locating hole on cylinder cap, and alignment pin II is suitable with the spark-plug hole on cylinder cap; Guide plate is provided with gathering sill, pressure head 1 slides and is located in the gathering sill of guide plate, and the draw-in groove 11 blocking pipe fitting is provided with in the pressure head end of guide plate side, the pressure head of guide plate opposite side is provided with the spacer pin 2 stretched out, spacer pin 2 interference fit is located in the cylindrical limit pin hole 13 of pressure head, by spacer pin restriction hot air hose compression distance.
Pressure head 1 is provided with the spigot surface 12 suitable with the slip plane in gathering sill, limits by spigot surface 12 angle that hot air hose press-fits.
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 carry out press-fiting 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, ensures the stability press-fiting operation.
Utilize this frock to press-fit the pressing method of the hot air hose on cylinder cap, comprise the following steps:
1) first two alignment pins on guide plate are matched with the locating hole on the cylinder cap of engine, spark-plug hole, guide plate is located and is fixed on cylinder cap;
2) the installing hole place of cylinder cap put into by airduct of warming oneself, and utilizes the draw-in groove of pressure head to be stuck on hot air hose, makes pressure head compress hot air hose by the gathering sill guiding of guide plate;
3) knock pressure head upper end with "painted-face" character in opera, pressure head moves down and is fitted on the installing hole of cylinder cap by hot air hose, when spacer pin contacts with guide plate, stops knocking;
4) take off frock, hot air hose is press-fit into place.
Press-fiting in process, spigot surface limits the angle that hot air hose press-fits, what spacer pin limited hot air hose press-fits the degree of depth, utilize this frock to replace high assembly precision and rely on the present situation that completes of numerical control device, adopt assembling manually can realize press-loading process requirement, equipment cost is low, and press-fitting tool not easily breaks down, long service life.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
