Abstract
The utility model provides a moving double-driving device for a beam of a numerically controlled milling planer, which comprises guide rails and screw rod pairs which are fixed on a left side beam and a right side beam. The guide rails are in sliding connection with bottoms of the left end and the right end of the beam. The device is characterized in that the left end and the right end of the beam are respectively provided with gearboxes, one end of each gearbox is connected with a driving motor, and the inside of each gearbox is connected with a screw rod; and each gearbox consists of a rotary shaft and a gear, the driving motor is connected with the rotary shaft through a shaft coupling to drive the gear to rotate, and another gear engaged with the gear is inserted and connected with the screw rod pairs through a center-fixed nut. The moving double-driving device has the advantages that the processing accuracy and the processing speed of a milling machine are improved, and the service life of the milling machine is prolonged.
Description
Technical field
The utility model relates to a kind of digital control processing machinery, and the crossbeam that uses on particularly a kind of CNC planer type milling machine moves double-drive device.
Background technology
At present, what the device that the driving crossbeam moves in the conventional CNC planer type milling machine adopted is that screw mandrel rotates, and the mode that nut moves along screw mandrel, in the screw mandrel rotating process, because its length is long, it is unstable to cause it to rotate, and produces the phenomenon of swing, and machining accuracy and the process velocity that this phenomenon can influence milling machine occur, and influence the service life of milling machine.
Summary of the invention
The purpose of this utility model provides a kind of CNC planer type milling machine crossbeam that can effectively overcome the problems referred to above generation and moves double-drive device, and it not only can improve the machining accuracy and the process velocity of milling machine, and has prolonged the service life of milling machine.
The purpose of the utility model structure is achieved in that a kind of CNC planer type milling machine crossbeam moves double-drive device, it comprises guide rail and the screw pair that is fixed on the curb girder of the left and right sides, guide rail links to each other with two ends, the left and right sides basal sliding of crossbeam, it improves, the two ends, the left and right sides of crossbeam respectively are provided with gearbox, gearbox one end connects drive motors, links to each other with leading screw in it; Gearbox is made up of rotating shaft and gear, and drive motors connects the rotating shaft driven gear by shaft coupling and rotates, and wears with another gear of its engagement nut by center fixation to be connected on the lead screw pair;
Gear in the described gearbox is the zero-clearance gear;
Described screw pair is a ball wire bar pair.
In sum, the utility model CNC planer type milling machine crossbeam moves in the double-drive device, drive motors is given gear by shaft coupling with transmission of power, the nut of screw pair given transmission of power again by gear, and screw mandrel is fixed on the curb girder of the left and right sides, during work by bearing block, motionless and the nut of screw mandrel rotates, simultaneously nut drives crossbeam and moves along guide rail and screw mandrel, and rotatablely moving of so just will driving is converted to the lengthwise movement of crossbeam, being controlled by the numerical control driving governor synchronously of two drive motors.Because nut length is shorter, so more stable in the rotating process, this drive unit not only can improve the machining accuracy and the process velocity of milling machine, and has prolonged the service life of milling machine.
