Abstract
The utility model discloses a combined dismounting tool specially for internal-combustion engine piston set, mainly comprising a filament rod 1, a BC cylindrical ejector sleeve 2, a foldable adjustable loading device with variable diameter 3, a protective tile 4, a cylindrical locating sleeve 5, a cylindrical guide pin 6, a cylindrical adapter pipe 7, a thrust bearing 8, a screw disc of tightly clamping pin 9, a spiral handle for locking compass. The combined dismounting tools specially for internal-combustion engine piston set is suitable to repair various internal-combustion piston groups at home and abroad. The combined dismounting tools specially for internal-combustion engine piston set is easy in use and flexible to disassemble and assemble. The assembly of the combined dismounting tools specially for internal-combustion engine piston set can be completed in one time. The work efficiency can be enhanced by more than twenty 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, easily make piston distortion, axle sleeve damage, connecting rod bending with these method dismounting, have seriously influenced the precision of machine and the service life of parts.Simultaneously, also easily hinder the hand accident during with these method dismounting piston groups, bring unnecessary damages to the maintenance personal.
The purpose of this utility model is to overcome above-mentioned shortcoming.Design the special-purpose tool of a kind of piston in combination formula dismounting easy and simple to handle, that production is easy, installation is accurate, cheap, safe and reliable.
The purpose of this utility model realizes by following manner.A on screw mandrel 1
2The place screws on a B, C cylindrical shape ejector sleeve 2, puts cylindrical shape positioning sleeve 5, cylindrical shape guide finger 6 again.Then screw mandrel 1 is pushed from the piston boss hole of folding adjustable reducing harness body 3 sides, put again cylindrical shape adapting pipe 7, at last put thrust bearing 8 and locking spiral tray 9, by 8 rotations of rotational lock spiral shell dish 9, thrust bearing, by adapting pipe 7 transferring power, guide finger 6 reach advances piston pin or connecting rod small-end bearing or release and reaches preposition.Thereby finished the dismounting of piston group.
The advantage of the special-purpose tool of the utility model combined type dismounting be the piston of dismounting do not damage, indeformable, do not damage axle sleeve, connecting rod do not bend, safe in utilization, easy and simple to handle, install accurately, once mounting puts in place, assembly quality meets the requirements, significantly reduced labour intensity, increased work efficiency more than 20 times.
Below in conjunction with accompanying drawing detailed introduce the utility model.
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 by A
1, A
2Two sections whole formations, A
1, A
2Make the screw thread of two kinds of specifications.A
2Screw thread place dress B, the cylindrical shape ejector sleeve 2 of two different-diameters of C screw, put cylindrical shape positioning sleeve 5, cylindrical shape guide finger 6 again.From the piston boss hole, side of the harness body 3 of folding, adjustable, reducing, push.Put the different cylindrical shape adapting pipe 7 of two ends internal diameter, thrust bearing 8 and locking spiral tray 9 again, all these dismountable parts all are enclosed within on the rhizoid bar.
The special-purpose tool of the utility model combined type dismounting is not limited to be applied in a kind of internal combustion engine group.According to the protection of transposing B, C cylindrical shape ejector sleeve 2, interchangeable, reducing harness body 3 watts 4, cylindrical shape positioning sleeve 5, be the internal combustion engine group of dismantled and assembled several series of products.As: 212 series, 195 series, 190 series, liberation, east wind etc. reach a tool and use more.Select 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 special-purpose tool of the utility model combined type dismounting can also be used for other mechanical axle sleeve of dismounting.
