Abstract
The invention relates to a device and method for machining a connecting rod on a fly-cutter machine tool. The fly-cutter machine tool is special equipment used for machining a crankshaft. V-shaped supports on supporting machine tool bodies are used for positioning and fixing the crankshaft, and a rotating cutter rack can rotate around a crankshaft turning neck to cut the crankshaft turning neck. If a connecting rod is machined on the fly-cutter machine tool, due to the fact that no shaft neck used for positioning is arranged at the two ends of the connecting rod, the V-shaped supports cannot be used for positioning; if two shaft necks used for positioning are forged on connecting rod blank, the blank manufacturing cost is increased, and the machining processes are increased. According to the device and method, the two V-shaped supports on the fly-cutter machine tool are each provided with a tip base, a movable tip and a bracket, the connecting rod is positioned and fixed through the tips at the two ends, the brackets are used for conducting auxiliary fixing on a workpiece, and the rotating cutter rack rotates around the rod body of the connecting rod to machine the connecting rod.

Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of device and method processing connecting rod on flying disc lathe.
The technical scheme that the present invention solves this technical problem employing is: a kind of device of flying disc machine tooling connecting rod, its main body is arranged on two supporting beds dead head with it respectively, rolling center and bracket, dead head top is recessed semicircle, there is U-type groove below, bottom land is the convex semicircle with top semi-circular concentric, V-type supports in the U-type groove of insertion dead head, supporting and location is carried out to the convex semicircle of bottom land, rolling center profile is cylindrical shape, be arranged on the recessed semicircle of dead head, by pressing plate, the rolling center of Telescopic movable is fixed on dead head, tailstock sleeve in rolling center regulates flexible by screw rod.The V-arrangement supporting lathe bed supports front end face installation bracket.
Rolling center structure comprises tailstock sleeve, screw rod, top, handwheel.Hand wheel rotating screw rod, drives tailstock sleeve to move forward and backward by the external screw thread of screw rod and the screw-internal thread fit of tailstock sleeve, and what make on tailstock sleeve is top elastic.
For making apparatus of the present invention install firmly, support supporting V-type pressing plate with V-type, package unit compresses by bolt, the rear portion jack of dead head, pressing plate, screw rod carry out fastening.
Before and after support lathe bed V-arrangement support and all apparatus of the present invention be installed, and supporting the spacer thickness between the convex cylindrical of dead head by adjustment V-type, is that two top central axis are coaxial with the gyroaxis of circular cutter holder.
Utilize apparatus of the present invention in a method for flying disc machine tooling connecting rod, comprise the following steps.
1) connecting rod blank checked and rule, drawing center line at two ends.
2) on boring and milling machine, by connecting rod blank two ends center line, drill centers.
3) respectively apparatus of the present invention are installed with it at two supporting beds of flying disc lathe, connecting rod blank are winched on pivoted loop lathe, and through pivoted loop knife rest, centre bore is withstood with top in two ends, lower end plane jack is supported on bracket, and compresses with pressing plate, and connecting rod is fixed can not rotate.
4) rod journal is through the circular cutter holder of pivoted loop lathe bed, move back to turret to the centre of gyration position consistent with connecting rod center, cutter rotates with circular cutter holder and carries out turning to connecting rod neck, by knife rest X-axis and the numerical control linked turning coupler-point curve of pivoted loop lathe bed Z axis.
