Engine Piston Connecting Rods

Compound broaching device for connecting rods :
The invention relates to a composite rod broaching device and the connecting rod composite broaching process, including the vertical frame, the vertical vertical frame is provided with a connecting rod and connecting rod cap fixture fixture, the vertical frame is installed on the connecting rod and connecting rod cap broach broach, the connecting rod comprises a broach the connecting rod of the connecting rod box broach, broach box is provided with a connecting rod and connecting rod with side broach broach, the connecting rod cap broach including rod Gellar knife box, the connecting rod Gellar knife box is provided with a connecting rod cap and the connecting rod cap with side broach broach, the connecting rod and the side broach the connecting rod with the upper and lower surface broach; can cover processing in a connecting rod and connecting rod at the same time, for loading and unloading the connecting rod and connecting rod cap, effectively improve the processing efficiency, only one time clamping can be completed The machining of the two sides and the joint surface of the connecting rod and the connecting rod cover does not need to be adjusted and replaced repeatedly, so as to effectively guarantee the quality of the product.

[a] sovereignty link composite broaching device, which comprises a vertical frame, the vertical vertical frame is provided with a connecting rod and connecting rod cap fixture fixture, the vertical frame is installed on the connecting rod and connecting rod cap broach broach, the connecting rod comprises a connecting rod composite broach broach box, the box is provided with a connecting rod connecting rod side broach broach and connecting rod joint surface broach, the connecting rod cap broach including rod Gellar knife box, the connecting rod Gellar knife box is provided with a connecting rod cap and the connecting rod cap with side broach broach, the connecting rod and the connecting rod side of broach with the upper and lower surface broaching tool set.

[b] The invention relates to a connecting rod, which can be a small connecting rod rotatably connected with a piston, having a separate configuration, can be rotatably connected with the crank rod hole is located in Dalian, between the connecting rod connecting rod head hole, Dalian rod hole has the connecting rod head is arranged in the connecting rod body side and screwed to the connecting rod connecting rod connecting rod arranged in cover on the cover on both sides of Dalian hole hole, the lower end of the connecting rod and arranged in the through holes and screw holes penetrating flush connecting rod, screw penetrating the through hole and is screwed into the threaded hole. According to the invention, the connecting rod of this type, the connecting rod in the deviation of the connecting rod cap on the side of the screw holes, in areas with depression, depression, pointing to the Dalian bar hole and set screw axis eccentric relative to the direction of. This type of connecting rod makes it possible to minimize the partial load in the area of the last thread turn of each thread hole, and thus greatly increases the service life of the connecting rod.
