Technical field

The utility model relates to a kind of efficient edge milling machines, belongs to machining equipment.

Background technology

The working method of existing efficient edge milling machines is that workpiece is clamped and fixing, and milling cutter moves finishes cutting.The distance that milling cutter moves defines the length of processing, and as 4 meters, 6 meters, 9 meters, 12 meters, the workpiece of processing is long more, and equipment is big more.The blade of existing milling cutter is arranged radially, and blade damages easily during rotary cutting, causes disconnected cutting.

Summary of the invention

The purpose of this utility model is, a kind of new and effective edge milling machines is provided, and this function is milled the limit continuously, the processing length scope without limits, and equipment volume is little, another purpose of present technique is the service life of improving cutting quality, prolonging cutter.

The technical solution of the utility model is, a kind of efficient edge milling machines, comprise frame, milling cutter, jig, it is characterized in that: jig is made up of two groups of rubber rolls of upper and lower correspondence, the axle two ends of organizing each rubber roll down are by frame support, for flexibly connecting, the axle of rubber roll is connected with motor by sprocket wheel, chain drive, watt box of bearing, bearing is housed on the axle of last group of each rubber roll, watt box of bearing is lifted on the support arm of frame by glue roller regulating mechanism, the card seam of organizing up and down between the rubber roll is relative with milling cutter, and the milling cutter that milling cutter is packed on the support arm facade rotates on the governor motion.Described glue roller regulating mechanism, constitute by thickness governor motion and balance adjustment mechanism, the thickness governor motion is that the leading screw that is threaded is housed on the support arm of frame, leading screw lower end and eccentric shaft are connected, eccentric shaft is contained in the eccentric bushing, eccentric bushing by transmission mechanism with compress spanner and be connected, balance adjustment mechanism is in described eccentric bushing outside sleeve pipe to be housed, sleeve pipe both sides radially are connected with trunnion shaft respectively, balance set is housed on the trunnion shaft, clamp shaft and last, following two connecting plates are connected, and clamp shaft is connected by upper plate and balance set, and clamp shaft is connected by watt box of lower plate and bearing.Described milling cutter is a taper, and helical tooth is arranged on the conical surface.

In the card seam of organizing up and down between the rubber roll, workpiece contacts with milling cutter present technique with workpiece clamp, and workpiece moves, milling cutter rotates and realizes milling the limit.Present technique is compared advantage with existing efficient edge milling machines: it is unrestricted 1, to mill edge lengths, owing to organize the rubber roll rotation up and down workpiece is continuously moved forward, realize milling continuously the limit, prior art is that milling cutter moves on lathe, and displacement is subjected to the lathe length restriction.2, the circular knife of present technique is the feed of rolling cutting type, compares with existing feed mode, has prolonged cutter life, and feed is steady, constantly cuts, thereby has improved work quality and efficient, has saved cutter.3, the volume of lathe is little, mills the volume that edge lengths need not to increase lathe because increase, and is so this machine cost is low, in light weight, energy-conservation.4, easy to adjust, the roll adjustment wide ranges of thickness, rotational lead screw can make on the group rubber roll or down and move, and change the card seam width of organizing up and down between the rubber roll easily, adapt to the thickness of workpiece; Move and compress spanner, eccentric bushing is rotated, move on the group rubber roll or down in the drive, can realize fine setting easily.

The specific embodiment

Efficient edge milling machines has frame, and frame comprises base 19, upright arm 20, support arm 2.The jig of efficient edge milling machines is made of every group of 4 rubber rolls arranged side by side upper glue roller 9, the lower rubber roller 10 of correspondence.The axle of 4 lower rubber rollers 10 is supported by the base 19 of frame, on the axle of 4 lower rubber rollers sprocket wheel 11 is housed respectively, each sprocket wheel is connected by chain, and

sprocket wheel

11,17 connects by chain 12, is driven by reducing motor 18.The axle of 4 upper glue rollers 9 is gone up watt box 24 that dress is equipped with bearing 23, bearing respectively, watt box 24 of each bearing is lifted on the support arm 2 of frame by glue roller regulating mechanism, organize up and down and form card seam together between the rubber roll, workpiece 22 is installed in the card seam, the working face of workpiece is relative with milling cutter 14, milling cutter 14 is packed in milling cutter and rotates on the governor motion, and milling cutter rotates governor motion and is contained on the upright arm 20 of frame.
