But, the engine of novel Modern Engine piston light-weight design is in order to improve performance, to reduce oil consumption, the design that all adopts lightweight, reduction frictional dissipation, reducing piston compression height and skirt section length is important measures that reach engine piston light-weight design.Along with the structural change of piston, piston ring, the shortening of piston length, cause new work engine piston to adopt the assembling of tradition band tapering guide pin bushing assembly tool very difficult, as easy as rolling off a log appearance is stuck, when serious, cause piston ring to damage, cannot meet assembling beat and quality requirement, and, first-time qualification rate is extremely low, and operator's labour intensity is large.
Utility model content
For the deficiency in background technology, the purpose of this utility model is to provide a kind of assembling difficulty that solves Modern Engine piston rod and engine cylinder hole, and can meet the station beat of modern production, better realize the piston rod assembling that piston rod part packs engine cylinder hole into and join guiding device.
For achieving the above object, guiding device is joined in the piston rod assembling of the utility model design, it is characterized in that: comprise guide forceps and guiding hammer; Described guide forceps comprises two and half round busses, and one end of two described half round busses is hinged, and the other end connects detachable handle; Described handle and two described half round buss contact-making surfaces are acute angle angle; Described guiding hammer comprises that conical body, the top of described conical body are dome, the bottom surface attended operation handle of described conical body.
Preferably, the end that is articulated and connected of each described half round buss comprises the connection annulus that is positioned at the setting of width two ends, between described connection annulus, is provided with spacing collar, and bearing pin is through described connection annulus and spacing collar; Described spacing collar is provided with banking pin, and described banking pin is connected with described bearing pin through the barrel of described spacing collar.By the articulated manner of this structure, can improve two and half round busses circularity closed together, thereby improve precision.
Preferably, between described conical body bottom surface and described lever, be provided with spacing section, the diameter of described spacing section is greater than the diameter of piston.Like this, the position of assembly can ensure to install time.
Preferably, between described conical body top and described dome, be provided with cylinder changeover portion.Like this, be beneficial to the machining accuracy of controlling guiding hammer.
Preferably, also comprise guide plate, described guide plate comprises gripper shoe, and described gripper shoe middle part is provided with multiple through holes coaxial with cylinder cylinder hole; A sheathed guide pin bushing on each described through hole; Described gripper shoe bottom surface is provided with feet.Like this, play protection cylinder junction surface by guide plate and avoid colliding with, and have certain guide effect.
Further preferred, described gripper shoe two ends are along its length provided with mounting hole.Like this, be beneficial to installation guide plate.
The beneficial effects of the utility model are: overcome and in assembling process, be subject to piston skirt size short-range missile easily to depart from easily stuck difficulty of piston ring groove to bad and thin type piston ring, design specialized clamp compression ring leads, and special protection guide plate prevents bump injury.And cost is low, simple in structure, can be applied to the assembling of various piston rod groups, require also lower to operative employee's technical merit.
