Abstract
The utility model relates to a left and right headstock synchronous servo rotation device of numerical control crankshaft grinding machine, which comprises a left and right headstock arranged on the planker of the numerical control crankshaft grinding machine. The device is characterized in that a first AC servo motor is arranged on the left headstock and drives the left chuck of the left headstock to rotate through a first belt transmission assembly; a second AC servo motor is arranged on the right headstock and drives the right chuck of the right headstock to rotate through a second belt transmission assembly; and the first and second AC servo motors are the same type and are controlled by the numerical control system of the crankshaft grinding machine. The utility model has the advantages that the device can keep the left and right headstocks of the crankshaft grinding machine to rotate synchronously, overcome the error caused by mechanical transmission, ensure the crankshaft accuracy after grinding, and improve the qualification rate.
Description
Technical field
The utility model relates to a kind of numerical-control crankshaft grinding machine left and right sides headstock synchronous servo whirligig.
Background technology
Add man-hour at common cylindrical grinder, workpiece is installed between the top and tailstock center of workpiece spindle box, and obviously, the grinding of bent axle can not be adopted this installation way.The grinding of bent axle need be processed on special purpose grinder.The installation way of bent axle on special purpose grinder is very big to the precision influence of processing the back bent axle.Common installation way is that bent axle one end is clamped on the left headstock, and another is clamped on the right headstock, and the left headstock drives the right headstock by mechanical transmission mechanism and rotates synchronously, to guarantee the precision of bent axle.But, because mechanical transmission mechanism exists gap and error, can not guarantee accurately that the left headstock and the right headstock rotate synchronously, thereby influence the bent axle precision after the grinding, and then influence the service behaviour of engine, but also the overslaugh operation.Therefore, existing synchronous rotating machinery transmission need be improved.
Summary of the invention
The purpose of this utility model provides a kind of numerical-control crankshaft grinding machine left and right sides headstock synchronous servo whirligig, and it can make the left and right sides headstock of crankshaft grinding machine keep rotation synchronously, guarantees the bent axle precision after the grinding, improves product percent of pass, and easy to operate.
Numerical-control crankshaft grinding machine described in the utility model left and right sides headstock synchronous servo whirligig, comprise the left headstock and the right headstock that are arranged on the numerical-control crankshaft grinding machine planker, it is characterized in that: be provided with first AC servo motor on the left headstock, first AC servo motor drives the left chuck rotation of the left headstock by first belt drive component; Be provided with second AC servo motor on the right headstock, second AC servo motor drives the right chuck rotation of the right headstock by second belt drive component; First AC servo motor and second AC servo motor are same model, all are subjected to the control of crankshaft grinding machine digital control system.
The utility model with traditional by machine driving-be that motor of the left headstock is delivered to the right headstock to reach synchronous rotation by travelling gear etc., each AC servo motor reaches the left and right sides headstock by control system and rotates synchronously about becoming, to guarantee the bent axle precision after the grinding, improve product percent of pass.
Described numerical-control crankshaft grinding machine left and right sides headstock synchronous servo whirligig, the gearratio of its first belt drive component and second belt drive component equates.
The utility model prior art is compared and had the following advantages: it can make the left and right sides headstock of crankshaft grinding machine keep rotation synchronously, has overcome the error that machine driving is brought, and guarantees the bent axle precision after the grinding, improves product percent of pass.
Description of drawings
Fig. 1 is that the utility model is installed in the schematic diagram on the numerical-control crankshaft grinding machine.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Referring to Fig. 1 and Fig. 2, the left headstock 1 is installed on the left end of numerical-control crankshaft grinding machine planker 9, with model is that first AC servo motor 3 of SGMGH-20ACA61 (also can select other model for use) is installed on the left headstock, makes first AC servo motor drive left chuck 5 rotations of the left headstock by first belt drive component 4;
The left headstock 2 is installed on the right-hand member of numerical-control crankshaft grinding machine planker 9, with model is that second AC servo motor 6 of SGMGH-20ACA61 (also can select other model for use) is installed on the right headstock, makes second AC servo motor drive right chuck 8 rotations of the right headstock by second belt drive component 7;
Add man-hour, the end that needs are processed is clamped on the left chuck 5, the other end is clamped on the right chuck 8, can carry out grinding behind the axis correction.Because the gearratio of first belt drive component 4 and second belt drive component 7 equates, first AC servo motor is identical with second AC servo motor, control by the adjusting of control system again, make the left headstock and the right headstock keep the synchronous rotation of height, thereby guaranteed the precision of bent axle after the grinding, product percent of pass improves greatly, and the clamping operation is not interrupted.
Claims (2)
1, numerical-control crankshaft grinding machine left and right sides headstock synchronous servo whirligig, comprise the left headstock (1) and the right headstock (2) that are arranged on the numerical-control crankshaft grinding machine planker, it is characterized in that: be provided with first AC servo motor (3) on the left headstock, first AC servo motor drives left chuck (5) rotation of the left headstock by first belt drive component (4); Be provided with second AC servo motor (6) on the right headstock, second AC servo motor drives right chuck (8) rotation of the right headstock by second belt drive component (7); First AC servo motor (3) and second AC servo motor (6) are same model, all are subjected to the control of crankshaft grinding machine digital control system.
