Description
Technical field
The present invention relates to the metal manufacture field, relate in particular to a kind of brill oilhole of connecting rod and building-block machine of cutting big end hole processed.
Background technology
Connecting rod is the strength member in the automobile engine, and it is connecting piston and bent axle, and its effect is that the reciprocating motion with piston changes rotatablely moving of bent axle into, and passes to bent axle to the power that acts on the piston with power output.The two ends of connecting rod are respectively equipped with big end hole and microcephaly hole, in process, need cut big end hole, form the body of rod and bowl cover; Owing to need in the motion process of connecting rod constantly to lubricate, therefore must on big end hole and microcephaly hole, bore oilhole respectively again; In traditional Machining of Connecting Rod process, normally the cutting of connecting rod with bore big small end oilhole and be divided into separately independently operation, process with different equipment, need multiple clamping to accomplish, working (machining) efficiency is low, and the product precision is difficult to reach requirement.
Summary of the invention
The purpose of this invention is to provide the brill oilhole of the processing connecting rod that a kind of machining accuracy is high, production efficiency is high and the building-block machine of cutting big end hole.
For realizing above-mentioned purpose, building-block machine of the present invention comprises board, cutting mechanism, two cover borehole drill constructions, positioning fixture; Borehole drill construction and positioning fixture are arranged on the board table top, and cutting mechanism and board table top are slidingly connected, and connecting rod to be processed is fixed on the positioning fixture; The rotary head of cutting mechanism is fixed with saw blade, and saw blade is aimed at the cutting position of crank pin end pore, and cutting mechanism drives saw blade and sets the cutting position cutting movement along big end hole; Borehole drill construction is provided with drill bit, and drill bit is respectively along the position feed motion of opening oilhole on crank pin end pore and the microcephaly hole in advance.
Adopt above design, in the time processing process, can accomplish and bore oilhole and cutting twice manufacturing procedure, improved the production efficiency of connecting rod; Simultaneously, connecting rod to be processed only need carry out No. one time clamping in the whole machining process process, has improved the precision of boring oilhole and cutting.
Borehole drill construction of the present invention is fixed on the board table top by the frame activity, the relative position and the supplying position scalable of itself and connecting rod to be processed.Adopt this design, can borehole drill construction be adjusted according to the needs of oilhole Working position.
Positioning fixture of the present invention comprises lower end limit clamp, compressing fixture and limit clamp, and the lower end limit clamp is fixed on the board table top, and connecting rod to be processed is arranged on the limit clamp of lower end, and it is from connecting rod supported underneath connecting rod; One side of compressing fixture is connected with the board table top by holder, and opposite side is fixed on connecting rod on the limit clamp of lower end from the connecting rod top; Limit clamp is fixed on the both sides of connecting rod to be processed, and it clamps connecting rod from the connecting rod both sides.The action of the clamping connecting rod to be processed of each anchor clamps is by air cylinder driven and control in the positioning fixture.Adopt this positioning fixture to fixedly secure connecting rod to be processed from a plurality of directions, when connecting rod to be processed is placed in the positioning fixture, the air cylinder driven anchor clamps are fixedly clamped to connecting rod.
In sum, the invention provides a kind of connecting rod of having integrated and bore the equipment of oilhole and two operations of connecting rod cutting, avoided the multiple clamping of connecting rod in the process, realized the relatively stable of connecting rod upper oil hole position.In addition, this equipment is easy to operate, has saved time and human resources, has improved production efficiency of products.
