Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a door and window corner cutting device. Background Art

[0002] During the production process of doors and windows, rounded corners are usually used at the four corners, which can effectively prevent sharp corners from injuring people and improve safety. Corner connectors are used to reinforce the connection between the horizontal and vertical frames. The structure has high strength and good stability, and will not crack or loosen.

[0003] However, when processing door and window frames, most workers step on the door and window frames with one foot and then cut them with a handheld cutting saw. This not only has low cutting efficiency, but also cannot ensure the consistency of the rounded corners, which reduces the quality of door and window processing. Therefore, we proposed a door and window corner cutting device to solve the above problems. Utility Model Content

[0026] The above scheme is adopted: the doors and windows are placed on the fixed table 83, the two cylinder twos 85 are started, the two cylinder twos 85 drive the two clamping plates 86 to move close to each other to center and clamp and fix the doors and windows, the front and back movement of the fixed table 83 and the doors and windows can be driven through the arrangement of the sliding grooves 81 and the electric sliding blocks 82, and then the corners of the back side or the front side of the doors and windows can be transported to the position below the gantry 2, and the center of the rotating shaft 705 is aligned with the centers of the corners of the doors and windows that need to be cut.

[0027] Furthermore, the two clamping plates 86 are both slidably connected to the top of the fixed platform 83, which facilitates the guidance of the clamping plates 86 and makes their movement more stable.

[0028] Further, refer to Figure 1 and Figure 2 The spacing adjustment mechanism 6 includes a driving motor 61 fixedly connected to one side of the box body 5, and the output shaft of the driving motor 61 is fixedly connected to the same bidirectional screw rod 62.

[0029] The above solution is adopted: by driving the motor 61, the bidirectional screw rod 62 is driven to rotate, and the bidirectional screw rod 62 drives the two movable seats 63 and the rotating shaft 705 to move closer to or away from each other, so that the center of the two rotating shafts 705 are aligned left and right with the center of the rounded corners on both sides of the door and window.

[0030] Further, refer to Figure 1-4 The synchronous cutting mechanism 7 includes a bidirectional motor 701 fixedly connected to the bottom of the box body 5, and a rotating shaft 705 rotatably connected to the bottom of the movable seat 63. The output shafts at both ends of the bidirectional motor 701 are fixedly connected to the driving shaft 702. The ends of the two driving shafts 702 away from each other are provided with a square groove 708. A square rod 703 is slidingly sleeved in the square groove 708. One end of the square rod 703 is fixedly connected to the rotating shaft 704. The rotating shaft 704 is rotatably connected to one side of the movable seat 63. One end of the rotating shaft 704 is fixedly connected to the active bevel gear 706. The rotating shaft 705 A driven bevel gear 707 is provided on the outer fixed sleeve, and two active bevel gears 706 are respectively engaged with the corresponding driven bevel gears 707.

A cutting knife 714 is fixedly connected to the output shaft of the servo motor 713.

[0031] The above scheme is adopted: according to the size of the cutting corner arc, tighten the fixing screw 710 so that its bottom end does not abut against the connecting rod 711, thereby not fixing the connecting rod 711, pull the mounting bracket 712 and the connecting rod 711 outward or push it inward, thereby adjusting the distance between the cutting knife 714 and the rotating shaft 705, thereby adjusting the size of the cutting corner arc, when the adjustment is completed, tighten the fixing screw 710 so that the bottom end of the fixing screw 710 firmly abuts against the top of the connecting rod 711, thereby fixing the connecting rod 711, due to the arrangement of the square rod 703 and the square groove 708, it does not hinder the adjustment of the distance between the two movable seats 63, and the square rod The limiting of 703 and the square groove 708 allows the driving shaft 702 to drive the rotating shaft 704 to rotate, the cylinder 13 drives the cutting knife 714 to move downward, the servo motor 713 drives the cutting knife 714 to rotate, and the output shafts at both ends of the bidirectional motor 701 drive the two driving shafts 702, the square rod 703, the rotating shaft 704 and the active bevel gear 706 to rotate synchronously. The two active bevel gears 706 drive the two driven bevel gears 707 and the rotating shaft 705 to rotate in the opposite direction. The two rotating shafts 705 drive the sleeve 709, the connecting rod 711, and the cutting knife 714 to revolve around the rotating shaft 705, thereby performing arc cutting on the two corners of the doors and windows.

[0032] Furthermore, two limit rods 4 are provided for sliding on the top of the gantry 2, and both limit rods 4 are fixedly connected to the top of the box 5, so as to facilitate guiding the box 5 and make its movement more stable and smooth.

[0033] The two cylinders 85 are started, and the two cylinders 85 drive the two clamps 86 to approach each other and clamp the doors and windows in the center. By setting the slide 81 and the electric slider 82, the fixed platform 83 and the doors and windows can be driven to move back and forth, so that the corners of the rear sides of the doors and windows can be transported to the bottom of the gantry 2, and the center of the rotating shaft 705 is aligned with the center of the fillet of the corner to be cut. Then, the driving motor 61 drives the rotation of the two-way screw rod 62, and the two-way screw rod 62 drives the two moving seats 63 and the rotating shaft 705 to approach or move away from each other, so that the center of the two rotating shafts 705 is aligned with the center of the fillet on both sides of the doors and windows, which is beneficial to the cutting operation of the corners of doors and windows of different sizes, thereby greatly improving the versatility and practicality of the device.

[0034] According to the size of the cutting corner arc, tighten the fixing screw 710, so that the bottom end does not abut with the connecting rod 711, and then the connecting rod 711 is not fixed, pull outward or push inward the mounting frame 712 and the connecting rod 711, and then the distance between the cutting knife 714 and the rotating shaft 705 can be adjusted, and then the size of the cutting corner arc can be adjusted. When adjusted, tighten the fixing screw 710, so that the bottom end of the fixing screw 710 abuts firmly on the top of the connecting rod 711, and then the connecting rod 711 can be fixed. Because of the arrangement of the square rod 703 and the square groove 708, it does not hinder the adjustment of the distance between the two moving seats 63. At the same time, the limiting of the square rod 703 and the square groove 708 makes the driving shaft 702 drive the rotating shaft 704 to rotate. Start the cylinder 3, the bidirectional motor 701 and the servo motor 713. The cylinder 3 drives the downward movement of the cutting knife 714, and the servo motor 713 drives the rotation of the cutting knife 714. The two end output shafts of the bidirectional motor 701 drive the synchronous rotation of the two driving shafts 702, square rods 703, rotating shafts 704 and driving bevel gears 706. The two driving bevel gears 706 drive the reverse rotation of the two driven bevel gears 707 and rotating shafts 705. The two rotating shafts 705 drive the sleeve 709, connecting rod 711 and cutting knife 714 to revolve around the rotating shaft 705 as the axis, and then the two corners of the door and window can be arc cut. When the cutting is completed, the cylinder 3 is started in reverse to make the box 5 move upward and reset. Through the feeding mechanism 8, the door and window can be moved, so that the two corners on the front side of the door and window move to the specified position, and then the two corners on the front side of the door and window can be arc cut according to the above steps. Because the two cutting knives 714 cut the two sides of the door and window synchronously, the consistency of the arc cutting is ensured, and the quality of the door and window corner cutting is greatly improved.
