Abstract
The utility model discloses a heavy numerical control roll grinder head frame pre-startup device; the left side of the shell of a head frame is provided with a starter motor; the output shaft of the starter motor is connected with a worm in a worm pair; a driving gear and an electromagnetic clutch in a first stage reduction gear set are arranged on the same axle with a worm gear which is meshed with the worm; a driving gear in a second stage reduction gear set is arranged on the same axle with a driven gear in the first stage reduction gear set; a drive gear is arranged on the same axle with a driven gear of the second stage reduction gear set; the drive gear and an external gear of a head frame dialing plate are meshed, separated or connected by an oil cylinder controlled by a numerical control system. The device can overcome the static friction between a work piece and a dragging rack when the head frame starts by mechanical, electrical and hydraulic integration as well as the numerical control system, so that the work piece can speed up in a short time and achieves the required rotating speed. The heavy numerical control roll grinder head frame pre-startup device has the advantages of simple structure, convenient adjustment, reliable motion, and capability of meeting the expected effect.
Description
Technical field
The utility model relates to a kind of heavy-duty numerical control roll grinder headstock pretrigger device, and especially a kind of stiction that overcomes workpiece and tray chamber can help the headstock to start the time quickens workpiece at short notice, reaches required rotating speed starting drive.
Background technology
At present, the headstock starting drive of using always on large and medium-sized roll grinder adopts the internal tooth engagement, and the oil pump rotation produces the principle of thrust.The space of this structure is restricted, and the thrust of output is less, and can't adjust.When the workpiece preponderance, reliable in action is difficult to guarantee.
Domestic also have the engagement of the external tooth of employing, but workpiece weight and reliability aspect are still waiting to improve.
Summary of the invention
The technical problems to be solved in the utility model is the stiction of heavy workpiece and tray chamber when overcoming the headstock and starting, and heavy workpiece is quickened at short notice, reaches required rotating speed, and a kind of heavy-duty numerical control roll grinder headstock pretrigger device is provided.
The technical solution of the utility model is: a kind of heavy-duty numerical control roll grinder headstock pretrigger device, comprise starter motor, body shell, the worm screw in the worm gear pair, worm gear in the worm gear pair, first order train of reduction gears driving gear and driven gear, driving gear in the train of reduction gears of the second level and driven gear, driven wheel, external gear on the headstock dial, oil cylinder, electromagnetic clutch, swivel joint and splined shaft.
Described body shell is equipped with starter motor above the left side, the output shaft of starter motor connects the worm screw in the worm gear pair, on the worm gear that is meshed with worm screw is coaxial, driving gear and electromagnetic clutch in the first order train of reduction gears are housed, on driven gear in first order train of reduction gears coaxial, driving gear in the train of reduction gears of the second level is housed, on driven gear in the train of reduction gears of the second level coaxial, driven wheel is housed, the cylinder body of oil cylinder and body shell are fixedly connected, the piston rod of oil cylinder is connected with splined shaft through swivel joint, and driven wheel is realized engagement or throw off being connected by the digital control system and the oil cylinder of electromagnetic clutch control with the external gear on the headstock dial.
Motor links to each other with digital control system; Electromagnetic clutch is realized driving-chain disengagement, adhesive and protection; Swivel joint is when operate as normal, and the protection oil cylinder turns round in case piston rod is relative with cylinder body; Driven wheel is in engagement in the home position, and is stressed to guarantee in the rigidity optimum state.
Description of drawings
