Model utility content
The purpose of this utility model is to overcome above shortcomings in prior art, and provide a kind of reasonable in design, can directly be processed into the engine link blank of the engine link of multiple different size, thereby the R & D Cost of solution connecting rod exploitation is large, the problem that the construction cycle is slow.
The technical scheme in the invention for solving the above technical problem is: this engine link blank, it is characterized in that: comprise microcephaly, shaft and major part, wherein on major part, be provided with the major part processing district for machining crankshafts mounting hole, on microcephaly, be provided with the microcephaly processing district for machining piston axle mounting hole, the left end of described microcephaly processing district is that radius is the path processing district of R1, the right-hand member of microcephaly processing district is that radius is the processing district, large footpath of R2, path processing district arranges processing transition zone between He great Jing processing district, microcephaly processing district entirety is O shape shape, described R1<R2, major part processing district offers preformed hole, preformed hole is by attachment hole and be arranged on the semicircle orifice on the attachment hole left side and the semicircle orifice on attachment hole the right forms, major part processing district entirety is 0 shape shape, the semicircle orifice on the attachment hole left side, the semicircle orifice on attachment hole the right, the center of circle of the center of circle of path processing district and processing district, large footpath is on same straight line.
As preferably, the radius of the semicircle orifice on the semicircle orifice on the utility model attachment hole left side and attachment hole the right is 23.5mm, the width of attachment hole is 6mm, described R1 is 16mm, R2 is 17mm, the width of processing transition zone is 12.4mm, and the center of circle of semicircle orifice on attachment hole the right and the distance of center circle of path processing district are from being 144.8mm.
The utility model compared with prior art, has the following advantages and effect:
1) simple and reasonable, in prior art, path processing district is circular, therefore the position of piston shaft mounting hole is unadjustable, in the utility model, utilize path processing district can process piston shaft mounting hole, and due to processing transition zone being set, therefore can adjust according to the distance between piston shaft and bent axle the operative position of piston shaft mounting hole, the home position of piston shaft mounting hole can move in processing transition zone, thereby process the piston shaft mounting hole that meets size and distance, make factory's a kind of connecting rod blank of only need to getting ready the goods can meet the Machining of Connecting Rod demand of many moneys motor, reduced R & D Cost, accelerated development process.
2) offer in advance preformed hole, during processing machining crankshafts mounting hole, go to expect less, can reduce time of machining crankshafts mounting hole, improved widely the efficiency of processing.
3) as improving, designed the general connecting rod size for conventional motor on market, improved the adaptability of product.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment partly cut open structural representation.
Fig. 2 is the utility model embodiment's structural representation.
