Tapering by guiding usefulness is a piston band piston ring group normal contraction.
For making the utility model more perfect, more detailed and concrete technical scheme below also further having proposed, to obtain best practical function, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Described tapering is divided into continuous guiding awl mouth and guiding taper hole, and described guiding awl mouth is located at endoporus aperture one end of slim piston ring erecting tools, and this aperture is the end that piston ring is packed into, and its tapering is greater than the tapering that is located at the guiding taper hole in the hole.
In the endoporus of described slim piston ring erecting tools, between the end face its guiding taper hole and slim piston ring erecting tools and that cylinder is fitted, be provided with columniform pilot hole, the aperture of described pilot hole is less than the aperture of cylinder.Little 0.01～the 0.02mm in aperture of the aperture ratio engine cylinder of described pilot hole.
Enter the pilot hole part more smaller from the tapered hole of guiding usefulness, make slim piston ring reach state in cylinder-bore than cylinder bore dia.
Described slim piston ring erecting tools is positioned at an end of guiding awl mouth, is provided with the assembling breach.
Establish and the corresponding seam of cylinder orifice shapes in the aperture of the end face that described slim piston ring erecting tools and cylinder are fitted.
Described slim piston ring erecting tools bottom surface is chamfering or add fixing structure not, and making does not have the gap between the two, guarantees that the piston ring group packs into smoothly.
The utility model adopts technique scheme, by specific purpose tool, solves the installation question of slim ring group; This tool construction is simple, and processing cost is low; Can guarantee the quality of assembling; Material is not had specific (special) requirements, and the cost of raw material is low; Improved the production efficiency of assembling.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: 1, assembling breach, 2, guiding awl mouthful, 3, the guiding taper hole, 4, pilot hole, 5, slim piston ring erecting tools.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1 for a kind of slim piston ring erecting tools, is columnar structure.When piston ring assembles, aim at applying with the cylinder aperture.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize solving the installation difficulty of slim piston ring group, the goal of the invention of enhancing productivity, the technical scheme that the utility model is taked is:
As shown in Figure 1, the endoporus of this slim piston ring erecting tools 5 provided by the utility model is axially arranged with one section tapering, and described tapering small end is towards the one side of fitting with cylinder.
Tapering by guiding usefulness makes piston drive piston ring group normal contraction.This device solves the installation difficulty of slim piston ring group, by the guiding tapering partly make piston band piston ring group enter the cylinder assembled portion, enter the cylinder hole then.Transition is mild, shrinks evenly, has guaranteed assembly quality.Above-mentioned assembly tool is by machining, and is higher to the inwall requirement on machining accuracy, and requiring has good abrasion resistance, and outer shape and size do not have specific (special) requirements.
For improving the utility model, also can implement the utility model by the following embodiment that provides:
Embodiment one:
Above-described tapering, be divided into continuous guiding awl mouth 2 and guiding taper hole 3, described guiding awl mouth 2 is located at endoporus aperture one end of slim piston ring erecting tools 5, and this aperture is the end that piston ring is packed into, and its tapering is greater than the tapering that is located at the guiding taper hole 3 in the hole.
Can be designed to 2 targeting parts, determine the angle and the length of cone angle guiding awl mouth 2 and guiding taper hole 3 according to design of part.
Piston band piston ring group is through guiding tapering part; the inlet of guiding tapering part guarantees that piston band piston ring group can enter under free state; be retracted to assembled portion gradually by guiding tapering part then, this process guarantees that piston band piston ring group catching phenomenon can not occur.
