Abstract
The utility model relates to a rolling machine for the round angles of crank shafts, which relates to a special device for producing the crank shafts and belongs to the technical proposal of the rolling machine for the round angles of crank shafts. The utility model comprises a machine frame and is characterized in that a left and a right sides of the machine frame are respectively provided with a hydraulic-motor headstock and a hydraulic-finial tailstock, a set of float rolling pliers is suspended above the machine frame, and the rolling head of the float rolling pliers is positioned between the hydraulic-motor headstock and the hydraulic-finial tailstock. With simple and reasonable structure, the utility model has no the function of outer force of damage quality to the crank shafts in the process of rolling. The utility model has strong adaptability to the rolling crank shafts and convenient maintenance, disassembly and replace. Rolling technology is accordant with production requirements.
Description
The utility model relates to the special equipment of Production of Crankshaft, belongs to a kind of technical scheme of crankshaft fillet roller press.
Along with the continuous development of auto industry, automobile industry is more and more higher to the manufacturing technique requirent of bent axle.Particularly high-quality bent axle, its axle journal root need pass through rolling and reinforcing technology.The present domestic high-caliber crankshaft fillet automatic rolling machine that do not occur as yet, the import equipment complex structure costs an arm and a leg, and can't adapt to the production needs of homemade bent axle.
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of simple in structure, easy to operate, processing technology to meet the crankshaft fillet roller press that high quality of production requires.
Described crankshaft fillet roller press, comprise frame, it is characterized in that frame the right and left has the hydraulic motor headstock, the top tailstock of hydraulic pressure respectively, one group of roll extrusion pincers that float is suspended to the frame top, and the milled head position of the roll extrusion pincers that float is between the hydraulic motor headstock and the top tail of hydraulic pressure.
This crankshaft fillet roller press, simple and reasonable, in the roll extrusion process, bent axle there is not the effect of damaging external force, can keep the original precision of bent axle.To strong by the adaptability of rolling crankshafts, and change, easy to maintenance, rolling technology meets production requirement.
Below in conjunction with Figure of description, the utility model is further described.
Fig. 1 is a crankshaft fillet roller press master TV structure schematic diagram;
Fig. 2 is a crankshaft fillet roller press plan structure schematic diagram;
Fig. 3 is the roll extrusion wrench structure schematic diagram that floats.
As shown in the figure, the anterior the right and lefts of frame 9 install the hydraulic motor headstock 10 and the top tailstocks 5 of hydraulic pressure, are used for clamping and turning crankshaft 11.The roll extrusion of unsteady roll extrusion pincers 4 comprises milled head 14, following milled head 13, and last milled head 14, following milled head 13 are made of rolling wheel 21 and last roll extrusion wheel seat 22, following roll extrusion wheel seat 23 respectively.By last milled head 14 and the monolithic jig arm 16 that is mated, milled head 13 and the biplate jig arm 18 that is mated constitute the scissor structure of the roll extrusion pincers 4 that float down.Monolithic jig arm 16 and biplate jig arm 18 are intersected by bearing pin 15 flexible connections, and its tail end is connected with the two ends of hydraulic cylinder 19 respectively, and 20 is bearing pin.The roll extrusion pincers 4 that float are suspended on the crossbeam 2 of frame 9 tops by suspension rod 3 and suspention piece 1, suspension rod 3 lower ends and unsteady roll extrusion pincers 4 flexibly connect, and 17 is bearing pin, and suspension rod 3 upper ends flexibly connect with suspention piece 1, suspention piece 1 is articulated on the crossbeam 2, and can be along crossbeam 2 axial displacements.Forward position, 9 end of frame is provided with the existing formula feeding manipulator 8 of pendulum, the lever bracket of swing type feeding manipulator 8 is connected with hydraulic cylinder 7, the lever bracket top of swing type feeding manipulator 8 is provided with work supporting block 6, and work supporting block 6 can be movable adjustable type structure, and corresponding with bent axle.Unsteady roll extrusion pincers 4 when 12 pairs of tail-brackets are static play the balanced support effect, and the roll extrusion of being convenient to float clamps 4 holding workpieces and therefrom takes out workpiece.When this machine uses, by swing type feeding manipulator 8 bent axle is swung to center line between the hydraulic motor headstock 10 main shafts and the top tailstock 5 of hydraulic pressure from the material loading position under, pin calmly and tail hold out against bent axle.The roll extrusion pincers 4 that float clamp bent axle, and when bent axle had been with rotation at the hydraulic motor headstock 10, the roll extrusion pincers 4 that float were forced to do complicated plane motion by the rotation of corresponding connecting rod neck.Rolling wheel 21 was both rotating around connecting rod neck center, was rotating around the alignment of shafts again, and whole unsteady roll extrusion pincers 4 are planar done to move or swing, have finished rolling technology in this process.
