[0041] Working principle: the edge pre-milling device is provided with a positioning assembly for the wood board 7, the positioning back plate 6 is always pressed against the wood board 7 under the driving of the swing in-out tool assembly, the contact surface of the positioning back plate 6 with the wood board 7 and the outer diameter of the cutting edge of the pre-milling cutter 8 move together, the more the moving amount, the greater the cutting amount, and vice versa, when the cutting amount is adjusted, it will not change, so that the wood board 7 and the cutting edge keep a certain distance, the wood board 7 is placed at a certain angle, and the cutting amount can be ensured within a certain range, and the servo motor 1 is controlled, so that the intelligent digitalization can be realized. In the swing in-out tool assembly, the swing power is provided by the cylinder 15, when the cylinder 15 is pushed out, the spring 17 is compressed and pushes the rotating arm 14 to rotate outward around the vertical shaft 23, and drives the high-speed motor 13 to rotate, this process is the in-cutting process, the spring 17 is always in contact with the wood board 7 under the action of the elastic force of the spring 17, so that the cutting amount is constant; the adjusting nut 35 is used to adjust the elastic force of the spring 17, the more the compression amount of the spring 17, the greater the elastic force, and the pressure of the wood board 7 received by the positioning back plate 6 is also greater, and vice versa; the return nut can be arranged at the end of the adjusting screw 16, when the cylinder 15 is retracted, the high-speed motor 13 is pulled back to the original position, that is, the tool is returned; the device adopts the swing in-out tool mode to cut the wood board 7, the rotating shaft and the bearing are wrapped up, the wood chips are not easy to enter, compared with the in-cutting mechanism of the straight line guide rail type, the device reduces the occurrence of in-cutting jamming, the in-out tool stroke amount can be adjusted, and the pressure of the wood board 7 pressed by the positioning back plate 6 can be adjusted. The wood board 7 is close to the positioning back plate 6, the pre-milling cutter 8 cuts the wood board 7, the cutting direction is clockwise, the circular feature at the top of the chip suction shield 9 is connected with the external air suction pipe, the wood chips are discharged from the air pipe, since the positioning back plate 6 has the function of guiding the wood chips to be discharged, the amount of wood chips splashing to the equipment can be greatly reduced, so that the wood chips attached to the device are reduced. The driving force of the screw rod two 11 can be manual or servo driven, the first cutting tool cuts part of the wood board 7, and the remaining part is cut by the original mechanism, the screw rod two 11 is adjusted, so that the outer surface of the positioning back plate 6 is tangent to the cutting edge of the pre-milling cutter 8, after the in-cutting of the mechanism, the outer surface of the positioning back plate 6 is in close contact with the surface of the wood board 7 cut by the first cutting tool, at this time, the cutting edge of the pre-milling cutter 8 is tangent to the cut surface, the pre-milling cutter 8 cuts the remaining wood board 7 counterclockwise, and there is no step phenomenon after two cutting processes, the positioning back plate 6 is provided with a blowing hole, the wood chips attached to the wood board 7 are blown away, the function of the brush 12 is also to clean the wood chips on the wood board 7, the positioning back plate 6 makes the wood board 7 cut more stably, and the cutting surface will not have step phenomenon after two cutting processes.When the side surface of the cut wood board 7 is found to be not perpendicular to the plane of the wood board 7, the perpendicularity of the cutter needs to be adjusted. The adjustment method is as follows: loosen the adjusting screw one 25, if the cutter rotation center line needs to swing to the + ° angle direction, loosen the nuts of the two adjusting screws two 26, then rotate the adjusting screw two 26 counterclockwise, make the threaded end surface of the adjusting screw two 26 away from the movable plate 20 by a distance, then rotate the adjusting screw three 27 clockwise, at this time it is found that the cutter rotation center line is pulled to the + ° angle direction by the adjusting screw three 27, after the adjustment is completed, rotate the adjusting screw two 26 clockwise, make the threaded end surface of the adjusting screw two 26 tightly contact the surface of the movable plate 20, finally lock the two adjusting screws two 26 and lock the adjusting screw one 25, if the cutter rotation center line needs to swing to the - ° angle direction, the steps are to loosen the adjusting screw one 25, the two adjusting screws two 26, rotate the adjusting screw three 27 counterclockwise, make the end surface of the screw head of the adjusting screw three 27 away from the adjusting screw one 25 by a distance, then rotate the adjusting screw two 26 clockwise, make the threaded end surface of the adjusting screw two 26 push the cutter rotation center line to swing to the - ° angle direction, after the adjustment is completed, rotate the adjusting screw three 27 clockwise, make the end surface of the screw head of the adjusting screw three 27 tightly contact the surface of the adjusting screw one 25, finally lock the nuts and lock the adjusting screw one 25, since there is only one position of the adjusting screw one 25 for locking the movable plate 20, the mechanism is not firm enough, so the steel ball roller 29 is added to press against the bottom of the movable plate 20 to improve the stability of the mechanism, since the steel ball can roll, after the steel ball roller 29 presses against the movable plate 20, it does not hinder the rotation of the movable plate 20, the structure can compensate for the error that the cutting surface of the wood board 7 is not perpendicular to the plane of the wood board 7 due to machining assembly and cutter wear, the rotation center of the mechanism coincides with the center of the cutter and the motor, that is, the gravity centers coincide, the structure is stable, the cutter center can be adjusted within a certain angle range in the ideal position (that is, perpendicular to the large plane of the wood board 7), the adjustment operation is simple, and the angle can be finely adjusted through the left and right rotation of the screw.
