Description

Technical Field

[0001] This utility model relates to the technical field of door and window processing equipment, specifically a cutting device for door and window construction. Background Technology

[0002] When installing doors and windows, a cutting machine is needed to cut the door frame panels in a specific direction so that the dimensions of the door and window panels meet the corresponding installation dimensions. At the same time, various factors need to be considered during the door and window cutting process to achieve the accuracy of the cutting and facilitate the subsequent installation and use of the doors and windows.

[0003] Chinese utility model patent CN217667982U discloses a cutting device for building door and window construction. This utility model includes a fixed base with locking components and an adjusting base. A cutting wheel is mounted above the fixed base and is fixedly connected to a cleaning guide seat located on the upper end of the fixed base. The adjusting base is positioned on one side of the fixed base and is movably connected to the fixed base via a screw drive. The cleaning guide seat includes a slide rail mounted on the upper end of the fixed base, a slider at the upper end of the slide rail, and a brush plate on one side of the slider, with one end of the brush plate extending above the adjusting base. This utility model differs from traditional cutting devices in that the plates used to fix the door and window frames are designed as separate units, allowing for adjustable spacing according to different lengths and widths of door and window frames, thus broadening its applicability. Furthermore, during cutting, the brush plate on the cleaning guide seat moves along with the cutting wheel, and a pump sweeps away dust and debris from the frame, facilitating worker operations.

[0004] However, the device lacks a mechanism for fixing door and window panels, which may cause the panels to move around randomly, affecting the cutting effect. Utility Model Content

[0024] Please see Figure 1-4 A cutting device for door and window construction includes a main body 1 and a door and window template 3. The main body 1 has a slag trough 22, and a support seat 20 protrudes upward inside the slag trough 22. The top of the support seat 20 has a rotating hole 16, and a rotating block 17 is rotatably installed in the rotating hole 16. A suction cup 21 is engaged with the rotating block 17, and a vacuuming mechanism 18 is arranged inside the suction cup 21. The door and window template 3 is adsorbed on the suction cup 21. A lead screw 5 is rotatably installed on the main body 1. A servo motor 4 is arranged on one side of the main body 1. One end of the lead screw 5 is installed on the action output shaft of the servo motor 4. A transmission slider 6 is threadedly connected to the lead screw 5. A mounting frame 7 is installed on the top of the transmission slider 6. A cutting mechanism 8 is arranged on the mounting frame 7. A support frame 9 is installed on the side of the main body 1 away from the lead screw 5. An electric telescopic rod 23 is installed on the support frame 9. A connecting rod 10 is installed on the action output shaft of the electric telescopic rod 23. A pressure plate 11 is installed on the end of the connecting rod 10 away from the electric telescopic rod 23.

[0025] Through the coordinated arrangement of the rotating block 17, suction cup 21, and pressure plate 11, the door and window template 3 can be placed on the suction cup 21 during use. The air inside the suction cup 21 is then removed by the vacuum mechanism 18, allowing the suction cup 21 to stably adhere to the door and window template 3. This completes the initial fixation of the door and window template 3. The door and window template 3 can be rotated at a certain angle along the rotating hole 16 via the rotating block 17 according to the angle to be cut. After the angle is adjusted, the pressure plate 11 on the connecting rod 10 can be driven by the electric telescopic rod 23 to descend vertically, thereby pressing and fixing the door and window template 3 and preventing it from moving during the cutting process.

[0026] Specifically, in this embodiment, four movable rods 12 arranged in a matrix are slidably mounted on the pressure plate 11. A rubber pressure block 14 is provided at the bottom of the movable rod 12, and a stop block is provided at the top of the movable rod 12. A spring 13 is sleeved on the movable rod 12, with one end of the spring 13 abutting against the pressure plate 11 and the other end of the spring 13 abutting against the rubber pressure block 14.

[0027] By cooperating with the rubber pressure blocks 14, the movable rod 12, and the spring 13, the rubber pressure blocks 14 can contact the door and window template 3 when the pressure plate 11 descends vertically. This causes the movable rod 12 to slide along the pressure plate 11, while simultaneously squeezing the spring 13. The elastic potential energy of the spring 13 allows the four rubber pressure blocks 14 to press firmly against the door and window template 3, thus achieving the pressing and fixing of the door and window template 3. At the same time, it can reduce the impact force on the door and window template 3 when the electric telescopic rod 23 drives the pressure plate 11 to descend vertically during the pressing process.

[0028] Specifically, in this embodiment, a docking groove 15 communicating with the slag trough 22 is provided on one side of the main body 1 of the device. A collection box 2 is slidably installed in the docking groove 15. The slag trough 22 is inclined, and the lowest end of the slag trough 22 corresponds to the opening edge of the collection box 2.

[0029] By setting up the collection box 2 and the slag trough 22, the debris can fall into the slag trough 22 during the cutting process and then fall into the collection box 2 along the slag trough 22, thus facilitating the collection of debris generated during the cutting process.

[0030] Specifically, in this embodiment, the suction cup 21 is provided with a plurality of air holes 19 that communicate with the vacuum mechanism 18.

[0031] Specifically, in this embodiment, a horizontal guide groove 24 is provided on one side of the main body 1 of the device, and a horizontal guide block 25 is slidably installed in the horizontal guide groove 24. The horizontal guide block 25 is installed on the transmission slider 6.

[0032] By setting the horizontal guide groove 24 and the horizontal guide block 25, the movement range of the transmission slider 6 can be limited, and the movement direction of the transmission slider 6 can be limited.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
