Abstract
The utility model discloses a built-up special tool for mounting or dismounting piston set of ic engine, mainly comprising a filament rod 1, a cylindrical locating sleeve 2, a cylindrical loading tool 3, a pyramidal guide pin 6, a cylindrical adapter pipe 7, a footstep bearing 8 and a locking screw disc 9. The built-up special tool for mounting or dismounting piston set of ic engine is suitable for repairing the piston sets of various ic engines at home and abroad. The built-up special tool for mounting or dismounting piston set of ic engine has the advantages of easy and convenient use, flexibility of mounting and dismounting and assembly in one time. The built-up special tool for mounting or dismounting piston set of ic engine can improve work efficiency by more than four times.
Description
The utility model is the special-purpose tool of a kind of internal combustion engine group combined type dismounting.
At present, people continue to use indigenous method dismounting internal combustion engine groups such as hammering, baked wheaten cake, oil are boiled, bastinade always, make easily with these method dismounting that piston distortion, axle sleeve damage, connecting rod bending, have seriously influenced the precision of machine and the service life of parts.Also easily hinder accidents such as hand during simultaneously, with these method dismounting piston groups.Bring unnecessary damages to the maintenance personal.
The purpose of this utility model is to overcome the shortcoming of said method.Design a kind of easy and simple to handle, produce easily, install accurate, safe and reliable piston assembly and disassembly apparatus.
The purpose of this utility model realizes by following manner.On a threads bar 1, put a cylindrical shape positioning sleeve 2 and harness body 3 successively, put a cone-shaped guide finger 6 and cylindrical shape adapting pipe 7 again, put a thrust bearing 8 and a locking spiral tray 9 at last.By rotational lock spiral shell dish 9, make thrust bearing 8, adapting pipe 7 and guide finger 6 reaches, piston pin or connecting rod small-end bearing are advanced or release the precalculated position, thereby finished the dismounting of piston group.
The advantage of the special-purpose tool of the utility model combined type dismounting is that the piston of dismounting is indeformable, does not damage axle sleeve, and connecting rod does not bend, safe in utilization, easy and simple to handle, install accurately, once mounting puts in place, assembly quality meets the requirements, significantly reduce labour intensity, improved work efficiency more than four times.
At length introduce the utility model below in conjunction with accompanying drawing.
The accompanying drawing of specification is the axial section of the special-purpose tool of the utility model combined type dismounting.
As can be seen from the figure, long filament bar 1 is made of A, B, three sections integral body of C.The A section is threaded, and B, C are the different cylinders of threadless diameter for two sections.At first cylindrical shape positioning sleeve 2 is enclosed within the B section of long filament bar 1, is inserted in a cylindrical shape harness body 3 with a through-core hole then, then be inserted in a cone-shaped guide finger 6, be inserted in the different cylindrical shape adapting pipe 7 of a two ends internal diameter, thrust bearing 8 and locking spiral tray 9 again.All these dismountable parts all are enclosed within on the threads bar 1.
The special-purpose tool of the utility model combined type dismounting is not limited only to be applied in a kind of internal combustion engine group, selects different sizes for use, can produce the dismantling device of the different model that is used for the different internal combustion engine groups of dismounting.In addition, the utility model combined type dismantling device also can be used for other mechanical axle sleeve of dismounting.
