Description

Technical Field

[0001] The invention belongs to the technical field related to building construction, and in particular relates to a mechanical positioning device for cutting a building construction plate. Background Art

[0002] Plates are flat rectangular building material boards made of standard sizes and used in the construction industry as components of walls, ceilings or floors. They also refer to metal plates made by forging, rolling or casting, and are divided into thin plates, medium plates, thick plates, and extra-thick plates. They are usually made into flat rectangular building material boards of standard sizes. During the construction process, the plates need to be cut into the required size for use. At this time, cutting machinery is needed to perform the cutting operation.

[0003] Problems with existing technologies:

[0004] 1. When cutting a board, the existing building board cutting device needs to measure the board with a ruler in advance, draw a cutting line on it, and then place it under the cutting machine for cutting. The operation is relatively cumbersome, which affects the cutting efficiency of the board.

[0005] 2. When the existing building board cutting device is cutting the board, the two sides of the cutting position of the board are prone to warping, which causes uneven cutting on both sides of the cutting position during the cutting process, thereby affecting the beauty of the cutting appearance of the board.

[0006] 3. Existing building board cutting devices easily generate a lot of dust and debris during the board cutting process. These debris and dust not only easily affect the safety of operators, but also the splashing of debris easily leads to inconvenience in cleaning after the board cutting is completed.

[0007] 4. The existing building board cutting device is not convenient for fixing the board during the cutting process, and the staff is often required to manually fix the material, which slows down the cutting process of the board, greatly increases the workload of the staff, and easily affects the cutting quality of the board, causing great inconvenience to the staff.

[0008] 5. The existing building board cutting devices have relatively simple functions during use, and most of them can only realize the basic cutting process of the board, and thus it is difficult to achieve different cutting requirements of the board, which affects the cutting efficiency of the board.

After the two ends of the plates are fixed, the motor 27 is started according to the demand for the cutting length of the plates. The motor 27 drives the threaded rod 4 to rotate through the rotation of its output shaft, and then with the cooperation of the set threaded plate 57, the fixing rod 3, the connecting frame 52, the fixing frame 18, the electric hydraulic rod 19 and the sleeve 17, the cross plate 54, the pressing mechanism 6 and the cutting dust removal mechanism 9 can be driven to move in the left and right directions, and the cross plate 54, the pressing mechanism 6 and the cutting dust removal mechanism 9 can be driven to move to the specified cutting position through the cooperation of the indicator arrow 8 and the scale plate 15.

[0051] After the adjustment of the positions of the horizontal plate 54, the pressing mechanism 6 and the cutting and dust removal mechanism 9 is completed, the two electric hydraulic rods 19 are started to drive the top mounting frame 99 to move downward. In the process of driving the top mounting frame 99 to move downward, the cooperation of the L-shaped toothed plate 21 and the gear 69 can achieve the effect of driving the two worm gears 610 to rotate. Through the rotation of the two worm gears 610, the cooperation between the worm gear 68, the rotating rod 2 67, the hinged plate 2 66, the hinged plate 1 63 and the connecting shaft 62 can drive the two pressing plates 2 61 to move downward a certain distance, and through the cooperation of the pressing plate 2 61, the horizontal plate 54 and the supporting roller 55, the left and right sides of the plate cutting position are fixed, further ensuring the stability of the plate in the subsequent cutting process. After the clamping and fixing of the plate is completed, the L-shaped toothed plate 21 and the gear 69 are no longer in meshing;

[0052] By continuing to drive the top mounting frame 99 downward, the cutting wheel 92 can be driven to move downward a specified distance with the cooperation of the set fixing rod 2 97, the connecting block 96, the mounting plate 95, the protective cover 917 and the rotating rod 3 93. In this process, the cutting motor 91 is started to drive the rotating rod 3 93 to rotate, and then the cutting wheel 92 can be driven to rotate. After the cutting wheel 92 moves downward to the specified position, the motor 2 911 is started to drive the transmission wheel 1 915 to rotate. The rotation of the transmission wheel 1 915 can drive the threaded rod 2 98 to rotate under the action of the set transmission wheel 2 916. The rotation of the threaded rod 2 98 can drive the cutting wheel 92 to move in the front-rear direction with the cooperation of the set connecting block 96, the fixing rod 2 97, the mounting plate 95, the protective cover 917 and the rotating rod 3 93, thereby achieving the cutting process of the plate;

[0053] During the process of cutting the plate, the protective cover 917 can shield the debris generated during the cutting process, thereby preventing the debris generated during the plate cutting process from splashing and affecting the safety of the operator and the surrounding environment. The collecting box 7 can collect the debris dropped during the plate cutting process. When a certain amount of debris is collected in the collecting box 7, the collecting box 7 can be conveniently removed from the device by pulling it forward, thereby conveniently cleaning the debris inside the collecting box 7.

[0054] During the process of cutting the plate, the dust collection device body 913 is started, and then the debris and dust falling on the upper end of the plate can be transported to the inside of the dust removal water tank 22 through the cooperation between the set three-way connecting pipe 914, the dust collection hood 918, the hose 912 and the inlet pipe 23. Under the action of the water added to the dust removal water tank 22, the debris and dust can be adsorbed, thereby avoiding the impact on the environment during the plate cutting process.

[0055] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
