The wood door-window section face miller
The present invention relates to a kind of milling device, especially for the wood door-window section face miller of processing wood section end face.
In prior art, the end face of wood door-window section is normally machined by the ahooting plane scouring machine, and equipment cost is high, uses cost high.And can not guarantee the not damaged of fabircated shapes fully; Common section bar face miller will process at section bar, when milling cutter will break away from section bar, tearing of wood section end face easily occur, cause the breakage of section material appearance, and produce mass defect.Thereby affect crudy, cause the raising of production cost.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of easy to process and can prevent the section bar face miller that section bar is torn.
The technical solution adopted in the present invention is: a kind of wood door-window section face miller, the sliding table that it comprises frame, is fixed on the head that is provided with milling cutter on described frame and is arranged on described head rear.The described head that is provided with milling cutter is equipped with two dish milling cutters simultaneously, and the milling opposite direction of milling cutter; Described sliding table can move left and right between two milling cutters by line slideway auxiliary, is provided with working plate and rotation location-plate on described sliding table; Described rotation location-plate is provided with location backup plate and hold down gag; Described frame is provided with dust exhaust apparatus.
Also be provided with main spindle box on the described head that is provided with two milling cutters, complete milling by polywedge bet, multi-wedge belt pulley, motor, and complete the lifting of milling cutter rotating speed by the ratio of two multi-wedge belt pulley diameters.
Be provided with two air springs in left and right on described sliding table, make the center of sliding table remain on the center of two milling cutters, and can automatically reset.
Described working plate is fixed on sliding table, be provided with three rollers on described rotation location-plate, three rollers rest on the sliding rail of working plate closely, can make to rotate location-plate rotation relatively on working plate, and the center of rotation is at the center of two milling cutters; Have circular arc T-slot and the angle graduated scale of fixing rotation location-plate on described working plate, the anglec of rotation that makes to rotate location-plate is more accurate.
The present invention compared with prior art have following some:
1. the present invention, by the profile milling cutter of the dish of two on head switched in opposite and the sliding table that can move left and right, effectively prevents tearing of section bar end face, has improved crudy.
2. the present invention, by working plate and rotation location-plate, can complete the processing of the section bar end face of different angles.
The present invention by rotation the roller on location-plate and the sliding rail on working plate, make the pivot of rotation location-plate fix on the center of two milling cutters, effectively reduced the appearance and size of whole equipment, reduced the complexity of mechanism.
4. the present invention, by manual fast fixture, makes equipment operating simple and convenient, and safe and reliable.

The specific embodiment
Below in conjunction with accompanying drawing and instantiation, the present invention is described in more detail.Timber window face miller comprises frame 1, is arranged on head section and workbench part on frame as shown in Figure 1 and Figure 2.Described head section comprises headstock 15 and is contained in the motor 14 of headstock 15 belows, by multi-wedge belt pulley 16, polywedge bet 17, multi-wedge belt pulley 21 and main spindle box 20, drive milling cutter 12 and do the high speed rotary motion, and the cutting direction of two milling cutters is contrary; The transmission of belt wheel has the purpose of raising speed simultaneously.
As shown in Figure 1, Figure 3, sliding table 2 is arranged on headstock 15 by line slideway auxiliary, and parallel with main spindle box installing plate 18, along line slideway auxiliary, moves left and right.The lower rear of sliding table 2 is equipped with and keeps it to be positioned at the air spring 22 at two milling cutter 12 centers, one end of air spring 22 is arranged on adjusting seat 24 by hold-down screw 23, adjusting seat 24 is fixed on frame 1, the other end pushes up the side of sliding table 2, this mechanism can make sliding table automatically reset, and guarantees that its center line overlaps with the central point of two milling cutters 12.
Working plate 3 is fixed on sliding table 2, and it is ring-like that working plate 3 profiles are processed to semicircle, and the center of its annulus is overlapped with two milling cutter central points; Angle graduated scale 4 is housed on working plate 3; Because institute's fabircated shapes end face is outside one's consideration except 90, also have 45 degree and other special angle, therefore location-plate is set as to rotatable rotation location-plate 5; Rotation location-plate 5 is the inner and outer ring rotation along working plate 3 by roller, and interior ring place arranges 1 roller, and the outer shroud place arranges 2 rollers, and the pivot that rotates thus location-plate just fixes on the central point of two moulding milling cutters.
Be provided with location backup plate 6 on rotation location-plate 5, pole 9 is fixed on the backup plate 6 of location, the height of hold-down mechanism is just realized by adjusting its position on pole, this hold-down mechanism is hand, make 7 liftings of section bar pressure head by rotating eccentricity handle 8, reality to the fast-holding of section bar with unclamp, simple to operation; Be provided with location-plate 11 on main spindle box installing plate 18, location-plate 11 can be adjusted its position along Y direction, be convenient to adjust the degree of depth of milling.
As shown in Fig. 1, Fig. 4, the top of head is provided with dust shield 25, and whole milling head has been covered fully, under the effect of baffle plate 10 and backboard 13, can siphon away in time adding the wood chip produced man-hour.The wood chip that can not siphon away in time also can be discharged by the discharge device in frame 1.
Do in sum following embodiment explanation:
As shown in Figure 1, 2, 3, as process the section bar end face of 90 degree, the set lever of rotation location-plate 5 is unclamped, make to rotate location-plate 5 under the effect of roller and working plate, along the mid point rotation of the two moulding milling cutter lines of centres, go to 90 degree positions of angle graduated scale, screw set lever 23.Section bar is placed on the rotation location-plate, according to milling depth, adjusted location-plate 11.Now the end face of section bar is between two milling cutters 12, rotating eccentricity handle 8 makes section bar pressure head 7 that section bar is fixed, and promotes sliding table 2 along the X-direction operation, makes a milling tool wherein cross the center of section bar, then oppositely promote sliding table 2, make the remaining part of another milling tool section bar.Now the end face of section bar is completion of processing, has effectively avoided the breakage of section bar.As the section bar end face of need processing 45 degree or other angle, can adjust arbitrarily the position of rotation location-plate 5, after locking rotation location-plate as stated above by the section bar completion of processing.
