the first step is as follows: and (4) checking: before the dovetail groove processing is carried out by the machine, the machine is checked;

the second step is that: placing and fixing the plate 4: manually placing the plate 4 on the supporting transverse plate 11, then utilizing a first air cylinder 15 to push the linkage plate 14 downwards, pushing the short rod 13 and the extrusion plate 12 downwards by the linkage plate 14, and mutually matching the extrusion plate 12 with the supporting transverse plate 11 to fix the plate 4;

the third step: adjustment of the distance between the slotter knives 284: after the plate 4 is fixed, the knob 2812 is manually rotated to rotate the second threaded rod 2811, under the limiting action of the rectangular groove 2810, the second threaded rod 2811 drives the sliding sleeve 2813 to do linear motion, the sliding sleeve 2813 drives the hinge rod 2814 to do telescopic motion, under the matching of the limiting groove 2815 and the sliding block 2816, the hinge rod 2814 drives the T-shaped plate 281 to do linear motion, the distance between the slotting tools 284 is adjusted, and after the distance between the slotting tools 284 is adjusted, the knob 2812 is stopped to rotate and the threaded rod is locked by a screw cap;

the fourth step: grooving: after the interval between the slotting tool 284 is adjusted, start No. two motor 282 earlier for the dwang 283 drives the slotting tool 284 and does high-speed rotation, then start No. two cylinder 26, No. two cylinder 26 promotes the movable block 25 backward, the movable block 25 drives dull and stereotyped 27 and T template 281 and moves backward, T template 281 drives No. two motor 282, dwang 283 and slotting tool 284 backward synchronous motion, make the slotting tool 284 can be impeld to panel 4 inside at rotatory in-process, slot to panel 4.
