A cutting and positioning device for metal doors and windows

Abstract

This application relates to the field of metal door and window cutting technology, and discloses a cutting and positioning device for metal doors and windows. The device includes a mounting plate with two connecting plates fixedly connected to its top side. By setting a first clamping plate and a second clamping plate, the metal door or window to be cut is placed on the top side of the mounting plate and aligned so that the cutting position is below the cutting blade. Two spiral rods are then turned sequentially, causing the second clamping plate to gradually move closer to the first clamping plate. At this time, the two first clamping plates and the two second clamping plates cooperate to clamp and limit the placement of the metal door or window on both sides. Meanwhile, the output shaft of the motor drives the cutting blade to rotate, and the transmission frame is manually controlled to flip downwards and move along the hollow transmission plate. Thus, the cutting blade can be used to complete the cutting of the metal door or window, ensuring that the metal door or window does not shift during the cutting process, thereby improving cutting accuracy, reducing limitations, and facilitating widespread use.

[0017] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] This application discloses a cutting and positioning device for metal doors and windows, referring to... Figure 1-3The system includes a mounting plate 1, with two connecting plates 2 fixedly connected to its top side. A hollow transmission plate 3 is rotatably connected to the opposite side of the two connecting plates 2. A transmission frame 4 is slidably sleeved on the outer side of the hollow transmission plate 3. A cutting blade 5 is rotatably mounted at the center of the transmission frame 4. A motor 6 is fixedly connected to the front side of the transmission frame 4, and the output shaft of the motor 6 is fixedly connected to the cutting blade 5. Two first clamping plates 7 are fixedly connected to the top side of the mounting plate 1. Two rectangular holes are formed on the top side of the mounting plate 1. Second clamping plates 8 are slidably connected to the inner walls of both rectangular holes, and spiral rods 9 are rotatably connected to the inner walls of both rectangular holes. The two second clamping plates 8 are threadedly sleeved with the two spiral rods 9 respectively. The system utilizes the first clamping plates 7 and the second clamping plates... 8. Place the metal door or window to be cut on the top side of the mounting plate 1 and align it so that the cutting position is below the cutting blade 5. Turn the two spiral rods 9 in sequence so that the second clamping plate 8 gradually moves closer to the first clamping plate 7. At this time, the two first clamping plates 7 and the two second clamping plates 8 cooperate to clamp and limit the metal door or window on both sides. At this time, the output shaft of the motor 6 drives the cutting blade 5 to rotate. Then, manually control the transmission frame 4 to flip down and control the transmission frame 4 to move along the hollow transmission plate 3. Thus, the cutting blade 5 can be used to complete the cutting of the metal door or window, and it can ensure that the metal door or window will not shift during the cutting process, thereby improving the cutting accuracy, reducing the limitations, and facilitating its widespread use.

[0019] In this application, rubber pads 10 are fixedly connected to the opposite sides of the two first clamping plates 7 and the two second clamping plates 8, and the four rubber pads 10 are symmetrically distributed. By setting the rubber pads 10, when the first clamping plates 7 and the second clamping plates 8 come into contact with the metal doors and windows, the rubber pads 10 can increase the friction during contact and at the same time avoid scratching the surface of the metal doors and windows during contact, thereby providing a certain degree of protection.

[0020] In this application, a guide rod 11 is fixedly connected to the inner wall of the hollow transmission plate 3, and the transmission frame 4 is slidably sleeved with the guide rod 11. By setting the guide rod 11, when the transmission frame 4 moves along the hollow transmission plate 3, the guide rod 11 is used to limit the transmission frame 4, so that the transmission frame 4 can move in a straight line and avoid deviation.

[0021] In this application, a hexagonal transmission block 12 is fixedly connected to the right end of each of the two screw rods 9. By setting the hexagonal transmission block 12, when the screw rods 9 are turned, the hexagonal transmission block 12 can facilitate the worker to use tools to turn them, thereby achieving the purpose of saving effort.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of the metal door and window cutting and positioning device in this embodiment is as follows: In use, the metal door or window to be cut is placed on the top side of the mounting plate 1 and aligned so that the cutting position is below the cutting blade 5. The two spiral rods 9 are then turned sequentially, causing the second clamping plate 8 to gradually move closer to the first clamping plate 7. At this time, the two first clamping plates 7 and the two second clamping plates 8 cooperate to clamp and limit the placement of the metal door or window on both sides. Simultaneously, the output shaft of the motor 6 drives the cutting blade 5 to rotate. Then, the transmission frame 4 is manually controlled to flip downwards and move along the hollow transmission plate 3. Thus, the cutting blade 5 can be used to complete the cutting of the metal door or window, ensuring the safety of the metal door or window. The cutting process does not deviate, thus improving cutting accuracy and reducing limitations, which is conducive to its widespread use. When the first clamping plate 7 and the second clamping plate 8 come into contact with the metal door and window, the rubber pad 10 can increase the friction during contact and prevent scratches on the surface of the metal door and window, thus providing a certain degree of protection. When the transmission frame 4 moves along the hollow transmission plate 3, the guide rod 11 limits the transmission frame 4, so that the transmission frame 4 can move in a straight line and avoid deviation. When the screw rod 9 is turned, the hexagonal transmission block 12 makes it easier for workers to use tools to turn it, thus achieving the purpose of saving effort.
