Description
Technical field
The utility model relates to a kind ofly dismantles the device of separation to automobile, the big end axle sleeve of engine connecting rod of motor cycle.
Technical background
The two ends of automobile, engine connecting rod of motor cycle are axle sleeve, and wherein the small end axle sleeve is connected with engine piston by a bearing pin, holds axle sleeve to be enclosed within on the bent axle greatly and is connected with bent axle.The standing part that big end axle sleeve is divided into movable part and combines as a whole with connecting rod, pressing is equipped with bolt on the standing part, and two parts are connected as a single entity with bolt and nut.When engine assembles, need earlier movable part to be separated from the standing part dismounting.Because it is tighter that bolt cooperates with big end axle sleeve movable part, it extracted from bolt with standing part separate not too easily.It is that the dotted line force way that adopts manual hard draw to pull is firmly realized that present dismounting separates, this kind mode damages the metallographic structure of part on the one hand easily, makes connecting rod have certain quality hidden danger, and it is wasted time and energy on the other hand, operating efficiency is very low, and operator's labour intensity is big.
External engine assembling producer, because engine output is bigger, generally be to adopt manipulator that connecting rod is dismantled separation, this kind dismounting separate mode automaticity is higher, but this kind equipment manufacturing cost costliness, amount to RMB more than 500,000 yuan, and do not comprise annual expense normal operation of equipment and maintenance.
The utility model content
The purpose of this utility model provides engine link provision for disengagement a kind of simple in structure, cheap, is guaranteeing to make the dismounting convenient separation of connecting rod easy under the prerequisite that the engine link quality is without prejudice.
Engine link provision for disengagement described in the utility model comprises that base, two is mutually parallel and is vertically fixed on gripper shoe on the base, and the top cover that is fixed on two gripper shoe tops, offer breach in two gripper shoes upper end, locating shaft is installed in the breach, locating shaft is made up of upper and lower two-semiaxle, wherein descend semiaxis to be fixed on the breach bottom of two gripper shoes, push rod is installed in the following semiaxis to be slidingly matched with following semiaxis, be provided with guide pillar between last semiaxis and the top board, to control vertically moving up and down of semiaxis; Two gripper shoe bottoms under locating shaft are mounted with alignment pin, are provided with jacking apparatus between two gripper shoes, can be with the push rod jacking vertically upward that is installed in down in the semiaxis.
Described jacking apparatus can be an action bars, and it is hinged on two gripper shoes middle parts by bearing pin, and the action bars front end be positioned under the push rod with push rod under end in contact.
Described jacking apparatus also can be pneumatic cylinder, end in contact under pneumatic cylinder piston rod top and the described push rod, and piston rod axis and push rod axis are located along the same line.
The engine link of laying down clamp nut is installed in (the wrist-pin end of connecting rod axle sleeve is enclosed within on the alignment pin on the locating shaft in the two gripper shoes outsides and the alignment pin, big end axle sleeve is enclosed within on the locating shaft, it cooperates is matched in clearance), start jacking apparatus, make the push rod vertical lifting that is installed in down in the semiaxis, push rod will push semiaxis and rise, in the uphill process, the guide pillar that is arranged between semiaxis and the top board play the guiding role, make the vertical steadily rising of semiaxis, break away from the bolt that is fixed in the big end axle sleeve standing part until the movable part that makes the connecting rod tip axle sleeve, thereby the movable part of connecting rod tip axle sleeve is separated with big end axle sleeve standing part, realize that the dismounting of engine link separates.
Engine link provision for disengagement described in the utility model is because simple in structure, so it is cheap, about 1200 yuans of hand provision for disengagement (jacking apparatus is an action bars) cost, about 2000 yuans of pneumatic type provision for disengagement (jacking apparatus is a pneumatic cylinder) cost, and this provision for disengagement convenient and reliable operation, can not cause damage, guarantee the quality of engine link, and manipulation strength can largely be reduced engine link; (on the locating shaft of each gripper shoe side, alignment pin, two connecting rods can be installed) because each detachable four connecting rods, so operating efficiency is significantly improved.
