[0030] Working principle:

[0031] Telescopic ladder processing metal opening limit work:

[0032] When a hole is needed for a metal part of the telescopic ladder, the part is placed on the groove processed at the upper end of the first box body 101, and then the external power supply of the electric telescopic rod 102 is turned on. The electric telescopic rod 102 starts to drive the vertical plate 103 to slide to the left in the slide groove processed on the inner wall of the first box body 101. The vertical plate 103 slides to the left and drives the first rack 104 to slide to the left in the slide groove processed on the inner wall of the first box body 101. The first rack 104 slides to the right and drives the gear 105 to rotate in the first box body 101 through the bearing, thereby driving the second gear 105 to rotate through the gear 105. The rack 106 slides to the left in the groove processed on the inner wall of the first box body 101, and the square plate 107 is driven to move relative to each other through the relative sliding of the first rack 104 and the second rack 106. The relative movement of the two square plates 107 can drive the vertical plate 108 to slide relative to each other in the groove processed in the first box body 101. In this way, the two vertical plates 108 can move relative to each other to tighten and limit the two sides of the parts. After the hole opening processing is completed, the electric telescopic rod 102 is controlled to reverse, and the vertical plate 108 releases the clamping of the metal parts of the telescopic ladder, and finally it is taken out.

[0033] Telescopic ladder processing metal position adjustment and hole opening work:

[0034] After the parts are limited, the external power supply of the second motor 202 is turned on, the second motor 202 starts to drive the worm 203 to rotate in the second box 201 through the bearing, the rotation of the worm 203 drives the worm wheel 204 to rotate in the second box 201 through the bearing, and the rotation of the worm wheel 204 drives the cylinder 205 to rotate in the second box 201 through the bearing. This movement can drive the drill bit at the right end to rotate in a circle through the cylinder 205, thereby adjusting the drilling position of the parts, and then starting the hydraulic cylinder 7 to drive the cross plate 8 to move to the right, thereby driving the drill bit at the lower end to move to the right through the cross plate 8. The drilling position is adjusted. When the drill bit 10 is adjusted to the drilling position required by the component, the second motor 202 and the hydraulic cylinder 7 stop moving. Then, the external power supply of the first motor 9 is turned on. The first motor 9 starts and drives the drill bit 10 to rotate through the coupling. Then, the external power supply of the third motor 4 is turned on. The third motor 4 starts and drives the threaded rod 5 to rotate through the bearing in the cylinder 205. The rotation of the threaded rod 5 drives the threaded seat 6 to slide downward in the slide groove machined on the inner wall of the cylinder 205, thereby driving the drill bit 10 at the right end to move downward through the threaded seat 6 to perform drilling processing on the metal components of the telescopic ladder.
