Abstract
The utility model provides an engine piston mounting tool which comprises a guide pipe. The guide pipe is in a truncated cone shape, the inner diameter of the large end face of the guide pipe is larger than the outer diameter of a piston ring, the inner diameter of the small end face of the guide pipe is equal to the outer diameter of the piston ring, and a holding portion is arranged on the outer wall of the guide pipe. A piston can be placed in the piston mounting tool from the large end face of the guide pipe in the truncated cone shape, the small end face of the guide pipe is placed above a cylinder hole, and therefore the accurate locating of the piston on the cylinder hole is achieved, and the abrasion between the outer wall of a piston body and the inner wall of the cylinder hole is avoided.
Description
Technical field
The utility model relates to the automobile engine field, particularly a kind of engine piston erecting tools.
Background technology
When installing, engine piston needs by hand piston to be installed in the cylinder cylinder hole, piston comprises piston only and piston ring again, because the external diameter of piston only is less than the internal diameter of cylinder, and the external diameter of piston ring is a bit larger tham the internal diameter of cylinder, this causes comparatively inconvenience in the piston installation process, cause the wearing and tearing between piston only outer wall and the cylinder hole inwall easily, and then have influence on the service life of piston and the normal operation of engine.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly makes engine piston install more convenient and do not damage the instrument in piston and cylinder cylinder hole.
For solving the problems of the technologies described above, the engine piston erecting tools that the utility model proposes comprises:
Guide pipe, described guide pipe be shaped as truncated cone, the internal diameter of the large end face of described guide pipe is greater than the external diameter of piston ring, the internal diameter of the small end face of described guide pipe equals the external diameter of piston ring; The outer wall of described guide pipe is provided with the grip part.
Preferably, also be provided with outstanding structure on the outer wall of described small end face.
More preferably, described outstanding structure is first flange.
More preferably, the hem width of described first flange is 8～10mm, and the limit height is 5～8mm.
Preferably, described grip part is second flange that is positioned on the large end face of described guide pipe.
More preferably, the hem width of described second flange is 5～8mm, and the limit height is 5～8mm.
Preferably, the height of described guide pipe is 120～160mm.
The utility model can be put into the piston erecting tools from the large end face of the guide pipe of truncated cone shape with piston, the small end face of guide pipe is placed on the top in cylinder hole, thereby realized the accurate location of piston on the cylinder hole, avoided the wearing and tearing between piston only outer wall and the cylinder hole inwall.
Further, the outstanding structure that arranges on the small end face outer wall helps the more convenient top that is placed on the cylinder hole of small end face.
Further, it is convenient that first flange can make the processing of outstanding structure.
Further, the hem width of first flange is set to 8～10mm, and the limit height is set to 5～8mm and is conducive to the top that small end face is placed on the cylinder hole better
Further, it is convenient that first flange can make the processing of grip part.
Further, the hem width of second flange is set to 5～8mm, and the limit height is set to 5～8mm workman's piston erecting tools of holding steadily that is convenient to operation.
Further, the height of guide pipe is set to 120～160mm and can makes things convenient for piston to put into the piston erecting tools.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model engine piston erecting tools.
Indicate as follows among the figure:
Guide pipe-1, small end face-2, large end face-3, outstanding structure-4, grip part-5.
The specific embodiment
For above-mentioned purpose, the feature and advantage that make utility model can become apparent more, below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the situation of the utility model intension, so the utility model is not subjected to the restriction of following public specific embodiment.
As shown in Figure 1, guide pipe 1 be shaped as truncated cone, the less end face of the diameter of described truncated cone is small end face 2, the end face that diameter is bigger is large end face 3, the outer wall of guide pipe 1 is provided with grip part 5.Those skilled in the art can expect easily, the grip part can have and is welded on the handle on the guide pipe outer wall or is fixed on multiple choices such as boss on the outer wall, in the present embodiment, grip part 5 is for being positioned at second flange on large end face 3 outer walls, grip engine piston erecting tools integral body for the ease of operating personnel with hand, hem width d that can second flange is set to 5～8mm, and the high h in limit is set to 5～8mm, can arrange flexibly as required in practical operation.
As shown in FIG., the engine piston erecting tools is placed on the cylinder hole better for convenience, outstanding structure 4 can be set at the outer wall of small end face 2, those skilled in the art can know easily, above-mentioned outstanding structure can be passed through realizations such as boss, reinforcement or flange, in the present embodiment, outstanding structure 4 is for being arranged on first flange on small end face 2 outer walls, for location engine piston erecting tools more easily, hem width that can first flange is set to 8～10mm, the limit height is set to 5～8mm, can arrange flexibly as required in practical operation.
In addition, in order better piston to be placed into piston erecting tools, height H that also can guide pipe 1 is set to 120～160mm, and those skilled in the art can select the height of guide pipe 1 according to the concrete model of piston.
In actual applications, earlier piston is put in the guide pipe 1 from large end face 3, again small end face 2 is aimed at the cylinder hole on the cylinder cylinder bodies, then used hand hammer to be tapped down in the cylinder hole by the piston that the piston erecting tools is positioned at top, cylinder hole, namely finished the installation of piston.
Though the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only be subjected to the restriction of claims, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
