The invention provides a device combined with two processes of drilling the oil hole for the connecting rod and cutting the connecting rod; the operation of repeatedly clamping the connecting rod during a processing process is avoided; the relative stability of the position of the oil holes on the connecting rod is realized; the device is convenient in operation; and the production efficiency of products is increased.
Description
Technical field
The present invention relates to metal processing sectors, particularly relate to a kind of process connecting rod brill oilhole and the building-block machine of cutting big end hole.
Background technology
Connecting rod is the strength member in automobile engine, and it is connected to piston and bent axle, and its effect is the rotary motion reciprocating motion of piston being changed into bent axle, and the power acted on piston is passed to bent axle with power output.The two ends of connecting rod are respectively equipped with big end hole and little head bore, in process, need big end hole to cut, and form the body of rod and bowl cover; Again owing to needing continuous lubrication in the motion process of connecting rod, therefore on big end hole and little head bore, oilhole must be bored respectively; In traditional Machining of Connecting Rod process, normally the cutting of connecting rod with bore large small end oilhole and be divided into separately independently operation, process with different equipment, need multiple clamping just can complete, working (machining) efficiency is low, and Product Precision is difficult to reach requirement.
Summary of the invention
The object 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 achieving the above object, building-block machine of the present invention comprises board, cutting mechanism, two cover borehole drill construction, positioning fixtures; Borehole drill construction and positioning fixture are arranged on board table top, and cutting mechanism and board table top are slidably connected, and connecting rod to be processed is fixed on positioning fixture; The rotary head of cutting mechanism is fixed with saw blade, and saw blade aims at the cutting position of crank pin end pore, and cutting mechanism drives saw blade along big end hole setting cutting position cutting movement; Borehole drill construction is provided with drill bit, and drill bit is respectively along the position feed motion of crank pin end pore and little head bore being opened in advance oilhole.
Adopt above design, can complete in time processing process and bore oilhole and cutting twice manufacturing procedure, improve the production efficiency of connecting rod; Meanwhile, in whole process, connecting rod to be processed only needs to carry out clamped one time, improves the precision of boring oilhole and cutting.
Borehole drill construction of the present invention is movably fixed on board table top by frame, and relative position and the supplying position of itself and connecting rod to be processed are adjustable.Adopt this design, according to the needs of machining of oil hole position, borehole drill construction can be adjusted.
Positioning fixture of the present invention comprises lower end limit clamp, compressing fixture and limit clamp, and lower end limit clamp is fixed on 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; The side of compressing fixture is connected with board table top by holder, and connecting rod is fixed on the limit clamp of lower end by opposite side above connecting rod; Limit clamp is fixed on the both sides of connecting rod to be processed, and it is from connecting rod both sides clamping connecting rod.In positioning fixture, the action of the clamping of each fixture connecting rod to be processed is by air cylinder driven and control.Adopt this positioning fixture can fixedly secure connecting rod to be processed from multiple directions, when connecting rod to be processed is placed in positioning fixture, air cylinder driven fixture is fixedly clamped to connecting rod.
In sum, the invention provides a kind of connecting rod that incorporates and bore the equipment that oilhole and connecting rod cut two operations, avoid the multiple clamping of connecting rod in process, achieve the relatively stable of connecting rod upper oil hole position.In addition, this equipment operating is convenient, saves time and human resources, improves the production efficiency of product.
