Abstract
The utility model relates to a piston installing guider, wherein an inner bore provided with conicity with a slight big upper portion is arranged on the guider, and diameter of the bottom of the guider is the same as that of a cylinder body. The piston installing guider has the advantages of being appropriate in size, convenient to operate, quite easy to push a piston into a cylinder, and ring clamping and ring breaking are prevented from happening; convenient to manufacture, low in labor and material costs, durable in use, strong in generality, capable of being applied to the assembling of a piston of a cylinder with a 81-millimeter diameter, such as a JV engine, an AJR engine and engines of Jetta and Audi and is not easily damaged any more after the guider is manufactured; safe and convenient to use, and any unsafe factors do not exist, and the guider reflects professional teaching characteristics.
Description
Technical field
The utility model relates to a kind of auto repair practice teaching aid, and especially a kind of piston is installed guider.
Background technology
According to the requirement of real standard of Automobile Service and vocational instruction, the piston rod assembly and disassembly reach more rering, are important projects of auto repair practice operation, relate to the grasp of multinomial skills training and necessary knowledge point.And Piston and rod assembly is installed is wherein main operation task.Through placing the gap-clearance of piston rings position; Confirm direction forward; The Piston and rod assembly of smearing number place cleaning machine oil need be assembled in the cylinder block, use as specific purpose tool with slip-joint pliers compression armful drum or the special-purpose compressor reducer of piston ring, makes the piston ring connection rod set install to the position.But use deficiency below above two kinds of instruments existence: one, tightly the back is loose inadequately or earlier like the slip-joint pliers clamping force, causes the piston ring diameter greater than cylinder bore, and cause piston has been advanced not cylinder; Two, because the gap that clamps is too big, be difficult for again observing, very easily knocking or under thrust, damaging workpiece, or in cylinder, blocking, cause the refitting of doing over again; Three, use in the Piston Compression device process, very easily hinder hand, have potential safety hazard; Four, damage the phenomenon of encircling with annular groove and happen occasionally, cause waste; Five, time-consuming.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of convenient piston of installing that guider is installed.
The utility model solves the technical scheme that its technical problem adopts: this piston is installed guider, and this guider is provided with endoporus, and its base diameter is identical with the cylinder block diameter, and endoporus has a bigger tapering of top.
As preferably, said guider bottom is provided with a step that the bottom surface is smooth.
As preferably, said guider surface is provided with annular knurl.
As preferably, the height of said guider is less than depth pistion.
The effect that utility model is useful is: one, suitable size, be convenient to operation, and very easily push piston in the cylinder, prevent the generation of snap ring abscission ring phenomenon; Two, easy to make, the cost fee of material is low, no longer damages after processing, and is durable in use, and highly versatile, can be used for the piston assembling of 81 millimeters cylinders of diameter, the engine of waiting for bus like JV, AJR engine and Jetta, Audi; Three, safe and convenient to use, there is not any unsafe factor, embody the vocational instruction characteristics.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the installation diagram of the utility model;
Description of reference numerals: guider 1, endoporus 11, step 12, annular knurl 13, cylinder block 2, piston 3, piston ring 31, connecting rod 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: like Fig. 1, this guider 1 is provided with endoporus 11, and its base diameter is identical with cylinder block 2 diameters; Endoporus 11 has a bigger tapering of top; Guider 1 bottom is provided with a step 12 that the bottom surface is smooth, and the height of guider 1 is 35 millimeters, less than piston 3 height.Be provided with annular knurl 13 on guider 1 surface, and the heat treatment of turning black, prevent to get rusty.
Three road compression ring and oil rings are arranged on the piston body; The principle concentric according to tapering put into guider 1 to piston that assembles three road piston rings 31 3 and connecting rod 4 assemblies, with suitable force urges piston 3 tops; Under the effect of tapering, make piston ring 31 be compressed to cylinder block 2 diameter dimensions automatically with one heart.After treating that piston ring 31 gets into tapering, guider 1 is placed cylinder block 2 tops, the power that acts on piston 3 tops pushes cylinder block 2 with piston 3 from guider 1 below; Because being arranged, step 12 planes do the basis; The perpendicularity of piston 3 entering cylinder block 2 is better, and size guaranteed and the identical size of cylinder bore, promptly 81 millimeters; Very easily push piston 3 in the cylinder block 2, prevent the generation of snap ring abscission ring phenomenon.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
