Description
Technical field
The utility model is related to a kind of piston pin tool specially for attaching and detaching.
Background technology
When the piston of compact internal combustion engine is changed, during dismounting semi-floating piston pin, due to semi-floating piston pin and link pin
Hole is tight fit, so easily cause piston pin deformation, hole wall being damaged, assembly precision cannot be guaranteed, and reduces and uses internal combustion
The machine life-span, improve cost.
Utility model content
The purpose of this utility model is that assembly precision cannot be guaranteed when solving the problems, such as dismounting semi-floating piston pin.
The technical solution adopted in the utility model is：A kind of piston pin tool specially for attaching and detaching, including screw mandrel, handle, first
Nut, bearing block, bearing, sleeve, screw rod and pilot spool, described bearing block are connected in the side of sleeve, described sleeve
It is socketed on outside bearing and one end of bearing is fixedly connected with screw mandrel, the screw mandrel is flexibly connected with bearing block, one end of screw mandrel is prolonged
The side extended away from bearing is located at outside bearing block, and first nut is arranged on handle and the first nut is fixedly connected in place
In on the screw mandrel outside bearing block.
The beneficial effects of the utility model are：Piston pin is dismounted using the set instrument, piston pin is unlikely to deform, and pressure is not stayed in hole
Trace, assembly precision is high, simple and efficient, easy to use.
Brief description of the drawings
Fig. 1 is schematic diagram when the utility model is used.
Shown in figure：1 screw mandrel, 2 handles, 3 first nuts, 4 bearing blocks, 5 bearings, 6 sleeves, 7 pistons, 8 second nuts, 9
Plain cushion, 10, piston pin, 11, screw rod, 12, connecting rod, 13 pilot spools.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described further.
Embodiment：A kind of piston pin tool specially for attaching and detaching, including screw mandrel, handle, the first nut, bearing block, bearing, set
Cylinder, screw rod and pilot spool, described bearing block are connected in the side of sleeve, and described sleeve is socketed on outside bearing and bearing
One end be fixedly connected with screw mandrel, the screw mandrel is flexibly connected with bearing block, one end of screw mandrel extends to side away from bearing
Outside bearing block, the screw mandrel that first nut is arranged on handle and the first nut is fixedly connected on outside bearing block
On.
Using preceding, prepare fitter's bench or vice, prepare the second nut（Second nut is of different sizes with the first nut）,
Need to be provided with piston and connecting rod in the internal combustion engine for install piston pin, the piston left and right sides is equipped with piston hole（With shown in accompanying drawing
Direction, for convenience of describing, is referred to as piston left hole and piston right hole）, connecting rod is provided with connecting rod pin-and-hole.
When piston pin is installed, first screw mandrel is fixed on fitter's bench or vice, nut is gone into certain position, screw rod
It is connected with one end of piston pin after through piston left hole and connecting rod pin-and-hole, the other end of piston pin loads onto plain cushion and the second nut,
Piston is fitted with sleeve after installing, the second nut of adjustment make pilot spool through entering link pin hole after piston left hole while
Make piston pin through piston right hole against link pin hole end surface, such as piston pin hole and connecting rod pin-and-hole reaches axiality requirement, rotate
Handle makes sleeve and piston outer wall tight connecting, and whether completely coaxially the nut of pretension second checks again for it, first slow if qualified
Handle is changed hands, checks whether piston pin has been enter into connecting rod pin-and-hole, such as very smoothly uniform again firmly to pull handle, piston pin is by lentamente
Correct position in press-in piston hole.The process for dismantling piston pin is opposite with above-mentioned steps.
Those skilled in the art may be used also it is to be understood that protection scheme of the present utility model is not limited only to the above embodiments
To carry out various permutation and combination and conversion on the basis of above-described embodiment, on the premise of without prejudice to the utility model spirit,
The various conversion that the utility model is carried out are all fallen within protection domain of the present utility model.
