[0026] For explanation, see Figure 2The AC motor 4 drives the worm 61 to rotate, and the worm wheel 63 meshes with the worm 61, driving the connecting column 62 to rotate synchronously, thereby driving the driving gear 64 to rotate, and then the driving gear 64 meshes with the rack 65, and then the rack 65 and the extension part 651 move along the limiting groove 12, so that the rack 65 can drive the movable plate 5 to move in the front and rear direction.

[0027] As a preferred embodiment, the second driving assembly 7 includes a main rotating shaft 71, a main gear 72, a connecting key 73, a slave gear 74 and a slave rotating shaft 75; one end of the main rotating shaft 71 is fixed to the end of the worm 61 away from the AC motor 4, and the other end of the main rotating shaft 71 is rotatably arranged in the movable plate 5, the main rotating shaft 71 is provided with a keyway 711 along the front-to-back direction, and the rear end surface of the movable plate 5 is linearly provided with a plurality of T-shaped ring grooves 1 inwardly along the left-right direction, and the front end of the main gear 72 is connected with a T-shaped ring 1. The T-ring 1 is rotatably mounted in a T-ring groove in the central portion, the connecting key 73 is fixed in the main gear 72, and the connecting key 73 is slidably mounted in the key groove 711 along the front-rear direction, the slave gear 1 74 is symmetrically arranged in two groups, each group is linearly arranged with a plurality of them, the front end faces of the plurality of slave gears 1 74 are connected with T-ring 2, and the plurality of T-ring 2 are respectively rotatably mounted in the remaining T-ring grooves 1, and the slave rotating shaft 75 is configured with a plurality of them, which are coaxially fixed in the corresponding slave gear 1 74.

[0028] For explanation, see Figure 3 to Figure 4 When the worm 61 rotates to drive the main rotating shaft 71 to rotate, the keyway 711 drives the connecting key 73 to rotate synchronously during the rotation process, so that the main gear 72 rotates, and then the main gear 72 drives the multiple slave gears 74 to rotate through meshing, thereby driving the multiple slave rotating shafts 75 to rotate.

[0029] The connecting key 73 can also move in the key slot 711 when rotating, that is, when the moving plate 5 moves in the front-rear direction, it will drive the main gear 72 and the connecting key 73 to move synchronously.

[0030] As a preferred embodiment, the drilling assembly 8 includes a main drill bit 81 and an auxiliary drill bit 82; the main drill bit 81 is fixed at the rear end of the connecting key 73, and the auxiliary drill bit 82 is configured in plurality and is coaxially fixed at the rear ends of the corresponding slave rotating shaft 75.

[0031] It should be explained that when the AC motor 4 is driven counterclockwise, the main drill bit 81 and the plurality of auxiliary drill bits 82 can drill holes in the wall panel 11 synchronously.

[0032] For details, please combine Figures 2 to 4When the wall panel 11 needs to be drilled, the AC motor 4 is started, and the AC motor 4 drives the worm 61 to rotate counterclockwise, and the worm wheel 63 meshes with the worm 61, driving the connecting column 62 to rotate forward, thereby driving the driving gear 64 to rotate forward synchronously, and then the driving gear 64 meshes with the rack 65, and the rack 65 will push the movable plate 5 to move toward the wall panel 11, thereby providing drilling force for multiple drill bits; in the above process, the worm 61 will also drive the main rotating shaft 71 to rotate clockwise, and the key slot 711 rotates counterclockwise to drive the connecting key 73 to rotate synchronously, so that the main gear 72 rotates clockwise, and then the main gear 72 drives multiple slave gears 74 to rotate through meshing, thereby driving multiple slave rotating shafts 75 to rotate, thereby providing rotational force for multiple drill bits; therefore, the AC motor 4 can provide drilling force for the drill bit while providing rotational force for multiple drill bits, so that multiple drill bits can complete drilling of the wall panel 11.

[0033] In addition, it is also necessary to explain that when the AC motor 4 is driven clockwise, the main drill bit 81 and the plurality of auxiliary drill bits 82 will turn in the opposite direction to that during drilling and gradually push out of the drilled hole, thereby being able to remove the debris in the hole drilled in the wall panel 11 .

[0034] As a preferred embodiment, the grinding assembly 9 includes an L-shaped rod 91, a protective cover 92, a connecting shaft 93 and a grinding disc 94; the L-shaped rod 91 is symmetrically configured with two ends thereof being respectively arranged on the left and right sides of the rear substrate 2, the protective cover 92 is fixed to the other ends of the two L-shaped rods 91, the connecting shaft 93 is rotatably penetrated in the protective cover 92, the grinding disc 94 is fixed on the outer wall of the connecting shaft 93, and the grinding disc 94 is tangent to the rear end face of the wall panel 11.

[0035] As a preferred embodiment, the third driving assembly 10 includes a second slave gear 101, a connecting rod 102, a pawl 103, a connecting cylinder 104 and a ratchet cylinder 105; a T-shaped ring groove 2 is also provided just above the T-shaped ring groove 1 in the central portion, a T-shaped ring 3 is connected to the front end surface of the second slave gear 101, the T-shaped ring 3 is rotatably arranged in the T-shaped ring groove 2, and the second slave gear 101 is meshed with the main gear 72, and the front end of the connecting rod 102 is also provided with a T-shaped ring groove 2. The shaft is fixed to the slave gear 2 101, the pawl 103 is rotatably set on the rear end outer wall of the connecting rod 102, and a torsion spring is connected between the rotating part of the pawl 103 and the connecting rod 102, the rear end of the connecting cylinder 104 is coaxially fixed on the connecting shaft 93, the ratchet cylinder 105 is coaxially fixed in the connecting cylinder 104, the pawl 103 is gap-engaged with the inner wall of the ratchet cylinder 105, and the pawl 103 is slidably set in the ratchet cylinder 105.

[0036] Please note that Figures 5 and 6When the AC motor 4 drives the worm 61 to rotate counterclockwise, that is, during the drilling process, the main gear 72 rotates clockwise, and drives the slave gear 101 to rotate counterclockwise through meshing, thereby driving the connecting rod 102 to rotate counterclockwise. Therefore, the pawl 103 is not limited by the circumferential direction of the ratchet cylinder 105, and the connecting rod 102 will rotate relative to the ratchet cylinder 105. At the same time, the connecting rod 102 and the pawl 103 will move into the ratchet cylinder 105. Therefore, during the drilling process, the grinding disc 94 remains stationary, thereby avoiding excessive grinding of the end surface of the wallboard 11 and causing wear to the original base surface of the wallboard 11; When the AC motor 4 drives the worm 61 to rotate clockwise, that is, during the process of chip extraction, the main gear 72 rotates counterclockwise, and drives the slave gear 101 to rotate clockwise through meshing, thereby driving the connecting rod 102 to rotate clockwise, so that the pawl 103 keeps meshing with the inner wall of the ratchet cylinder 105, so that the connecting rod 102 rotates synchronously with the ratchet cylinder 105 and the connecting cylinder 104, and then drives the grinding disc 94 to rotate synchronously, wherein the connecting rod 102 and the pawl 103 will move outside the ratchet cylinder 105, that is, while the chips in the hole are being extracted, the grinding disc 94 can grind the drilled end face to keep the end face of the wall panel 11 flat, and these two processes are carried out simultaneously, so that the processing time of the wall panel 11 can be shortened and the processing efficiency can be improved.

[0037] In summary, the AC motor 4 can not only drive the drill bit to drill the wall panel 11, but also drive the grinding disc 94 to intermittently grind the end surface of the wall panel 11, thereby reducing the use cost of the driving source, and can also integrate drilling and grinding to improve the processing automation capability.

[0038] As a preferred embodiment, the upper end surface of the rear substrate 2 is symmetrically provided with slide grooves 21 on both sides, the L-shaped rod 91 is slidably arranged in the slide groove 21, and a return spring 95 is connected between the L-shaped rod 91 and the inner wall of the slide groove 21.

[0039] It should be noted that, in the absence of external force, the grinding disk 94 is in close contact with the rear end surface of the wall panel 11. However, when the tips of multiple drill bits pass through the wall panel 11, the protruding parts of the multiple drill bits will overcome the resistance of the reset spring 95, so that the multiple drill bits will push the grinding disk 94 to move synchronously. Therefore, the extrusion force between the multiple drill bits and the grinding disk 94 is weakened, thereby preventing the drill bits from causing damage to the grinding disk 94. When the drill bits are retracted, the grinding disk 94 is restored to be tangent to the rear end surface of the wall panel 11 under the action of the reset force of the reset spring 95 and burrs are ground.

[0040] As a preferred embodiment, a rectangular through slot 22 is provided on the rear substrate 2 for accommodating the grinding disc 94 .

[0041] As a preferred embodiment, a counterweight block 51 is provided at the front end side of the movable plate 5. The counterweight block 51 can balance the forces on the front and rear sides of the movable plate 5, thereby enabling stable movement.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
