A concrete operating process is described below:
As shown in figure 14, in the time measuring wall angle, selecting button to switch by the interior exterior angle of function button 12 is interior wall angular measurement or outer wall angular measurement, and then push-and-pull slip gage beam II8 is to adapt to the measurement at interior wall angle, outer wall angle.Rotation measuring arm II8, fits respectively the measurement face 5a of gage beam I5 and one of them measurement face of gage beam II8 with two wall surfaces in corner.When rotation measuring arm II8, gage beam II8 can drive contiguous block 7 to rotate together, now, absolute type circle appearance grid angular transducer 1 will rotate contiguous block 7 the angle signal variation causing and output to data calculation processing unit 3, data calculation processing unit 3 will output to display unit 4 and show after angle signal computing, be that absolute type circle holds grid angular transducers due to what adopt, thereby what obtain is actual wall angle angle.Meanwhile, the vertical dip angle signal of the metope that the micro-thermojunction type Gravity accelerometer 2 of silicon also detects the measurement face 5a by gage beam I5 outputs to data calculation processing unit 3, now press the wall button in function button 12, data calculation processing unit 3 will be recorded wall angle and stablize demonstration, and the vertical dip angle of the metope simultaneously the measurement face 5a by gage beam I5 being detected also records preserves and automatically switch to measurement spring angle display mode.Then according to shown in Figure 15, the angled end-face 6a of wall corner line module 6 and angled end-face 6b are adjacent to respectively to wall and floor simultaneously, mark wall corner line module 6 face is upward TOP face 19, and mark wall corner line module 6 face is down BOT face 20.The dip angle signal between the wall corner line bottom surface 6c of wall corner line module 6 and metope is exported to data calculation processing unit 3 by the micro-thermojunction type Gravity accelerometer 2 of silicon, now press the SPRING button in function button 12, data calculation processing unit 3 will also be recorded wall corner line module 6 and the inclination angle of metope, and the difference of this twice inclination angle record is the angle at spring angle.Complete after the measurement of the above two angle, just can be according to the following equation:
(1)Bevel＝arcsin[cos|(wall/2)|*cos|(spring)|]；
(2)Miter=arctan[cot|(wall/2)|*sin|(spring)|]；
Carry out the calculating at bevel angle and miter angle.
Complete after the calculating at miter angle and bevel angle, ensuing work is exactly to show that by display unit 4 the miter angle calculating and bevel angle are changed into the prompting of mitre saw adjustment intuitively and wall corner line placement prompting by the frequency responses different from hummer 9 of different mimic diagrams, and the measurement adjustment and the wall corner line process operation that are directly used in mitre saw cutting angle guide.Concrete manifestation is as described below:
(1) adjustment at mitre saw bevel angle
The short BVL/RESET of pressing key is switched to bevel angle adjustment modes, as shown in FIG. 17 and 18, the angle value of now gage beam II8 relative measurement arm I5 measurement face 5a i.e. " ADJUST " prompt value can show, and point out the position at mitre saw bevel angle on the screen upper left side of display unit 4 with the mode synchronously simulating of indicator angle flicker (being expressed as dotted line in Figure 17) below the screen of display unit 4.According to the model of mitre saw, select rotation measuring arm II8 to the left or to the right, in the time that " ADJUST " prompt value and bevel result of calculation differ within the scope of 5 °, hummer 9 sends at a slow speed " beep ", " beep " prompt tone, in the time that " ADJUST " prompt value and bevel result of calculation differ within the scope of 2 °, hummer 9 sends " beep " fast, " beep " prompt tone, when differing 0.3 °, " ADJUST " prompt value and bevel result of calculation encloses when interior, hummer 9 sends " beep " prompt tone continuously, in the time that " ADJUST " prompt value just equals the bevel angle of screen top demonstration, now the angle of two gage beams is exactly bevel angle, clockwise shearing set nut 10 is locked gage beam II8.Then press the method shown in Figure 19, the measurement face 5a of gage beam I5 is adjacent to the lower platform face on mitre saw, swing mitre saw by saw blade by the direction of display unit 4 screen upper left side indicator angle prompting figure flickers (being expressed as dotted line in Figure 18) again, make saw blade adjust to the angle of inclination of fitting with gage beam II8, complete and cut sth. askew according to the required bevel angle adjustment of cutting.If there is no the indicator angle flash for prompting figure of screen top, process operation personnel just can accurately not judge the direction that saw blade swings, and are easy to cause the mistake on saw blade swaying direction.By the prompting of display unit 4 screen top indicator angle flickers, can allow knowing of operating personnel's visual pattern cut sth. askew according to the direction of saw blade swing, avoiding cutting sth. askew swings mistake according to saw blade direction, and the failure that causes mitre saw bevel angle to adjust.Utilize space to synthesize angle measurement unit simultaneously, just can facilitate the saw blade of the certificate that makes accurately to cut sth. askew to adjust to the cutting angle needing, and generally, process operation personnel need be by multiple surveying instrument by multiple different measurements, and the saw blade of the certificate that just can make to cut sth. askew is adjusted to the cutting angle needing.

(3) placement of wall corner line on buck
Complete after the adjustment at above-mentioned mitre saw bevel angle and miter angle, now the screen left side of display unit 4 can arrange the cutting that the angle of pointing out current mitre saw to mix up with graphics mode is applicable to Left or right and places moulding wall corner line according to cutting of above-mentioned miter angle and bevel, as shown in figure 16, show according to wall corner line placement direction instruction 26
or
on buck, place wall corner line, when what wall corner line placement direction instruction 26 showed be
time, prompting wall corner line is placed on the left side of saw blade and cuts; When wall corner line placement direction instruction 26 is shown as
time, prompting wall corner line is placed on the right of saw blade and cuts.On display unit 4 screens, can show the character of the location processing of " TOP " or " BOT " simultaneously, point out TOP face 19 or the bottom surface BOT face 20 of mark on wall corner line to cut by mitre saw locating piece, in the time showing processing character in " TOP " location on screen, the TOP face 19 of prompting wall corner line cuts by mitre saw locating piece; In the time showing the character of location processing of " BOT " on screen, the BOT face 20 of prompting wall corner line cuts by mitre saw locating piece.
Complete after the cutting of an edge forming wall corner line, as shown in Figure 23 and 24, counter-rotation gage beam II8, there is equally prompt tone prompting, in the time that screen top angles of display value just equals the miter angle of screen below demonstration, now the angle of two gage beams is exactly the horizontal angle of chamfer miter of the moulding wall corner line angle of another side, and clockwise shearing set nut 10 is locked gage beam II8.Then press the method for Figure 25, the measurement face 5a of gage beam 5 is adjacent to the locating piece on mitre saw, rotate mitre saw buck breach by indicator angle prompting figure again and adjust to the position of fitting with gage beam II8, on the screen of display unit 4, also can point out this moulding wall corner line is that TOP face 19 leans on mitre saw locating piece or BOT face 20 cuts by mitre saw locating piece.Operator is as long as just operate and can complete precise cutting according to prompting, and being stitched together of the wall corner line scarf that finally both sides can be cut, as shown in figure 26, forms a wall corner line unit.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
