Description

Technical Field

[0001] This utility model relates to the field of door and window frame production, and more specifically, it relates to a cutting and positioning auxiliary device for door and window frame processing. Background Technology

[0002] Doors and windows are very common in people's lives. Existing doors and windows are generally composed of metal frames and glass or other decorative materials. They facilitate people's entry and exit from buildings and allow light to pass through. When producing metal frames for doors and windows, it is often necessary to cut the frames. Before cutting the frames, the cutting position is usually determined. This is generally done by operators using handheld measuring tools to measure the length. However, since the frames are not fixed during the measurement process, any positional shifts can affect the accuracy of the measurement. After determining the cutting position, operators need to use tools to mark it. Because the surface of the metal frame is hard, it is difficult to leave marks with ordinary tools, making it difficult to accurately locate the cutting position and affecting the cutting precision of the frames.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cutting and positioning auxiliary device for processing door and window frames, which has the following advantages:

[0017] 1. This utility model, by setting a fixing structure, allows the second threaded rod to be rotated according to the thickness of the frame when the frame is installed on the entire structure. The second threaded rod is connected to the second fixing plate by threads, which drives the second fixing plate to move, thereby changing the distance between the first fixing plate and the second fixing plate. The metal frame is clamped by the first fixing plate and the second fixing plate, thus fixing the metal frame to the entire structure. This makes it easy to adjust the fixing structure according to the thickness of the frame, improves the applicability of the entire structure, and facilitates positioning assistance for different frames.

[0018] 2. This utility model, by setting up a marking structure, allows for accurate cutting positions to be measured using external measuring tools after the frame is fixed. When marking the cutting positions, the position of the lifting block is changed by the sleeve connection between the lifting block and the mounting column, and the cooperation between different positioning holes on the lifting block and the mounting column. This makes it easier for the marking needle to approach the frame surface. After the position of the lifting block is determined, the positioning rod is rotated, and the positioning rod is inserted into the positioning hole opened on the mounting column through the threaded connection between the positioning rod and the positioning hole, thus fixing the position of the lifting block. After fixing, the tip of the marking needle is brought into contact with the frame surface through the threaded connection between the marking needle and the moving plate. By repeatedly pulling the sliding column, the cutting position is marked on the frame by the marking needle, which facilitates accurate cutting of the frame by aligning the markings during cutting.

[0019] 3. This utility model, by setting up a main frame and a fixed fit, allows for the determination of the approximate cutting position by measuring the frame with an external measuring tool when positioning the cutting position of the frame. The first threaded rod is rotated, and through the threaded connection between the first threaded rod and the moving block, as well as the two threads with opposite directions on the first threaded rod, the moving block and the fixed structure are moved closer or further apart, so that the cutting position of the frame is located between the two fixed frames. This facilitates the approximate determination of the cutting position and the engraving of the metal frame. Attached Figure Description

[0031] In this embodiment, the main structure of the entire positioning auxiliary device is composed of the main frame 1, the fixing structure, and the engraving structure.

[0032] More specifically, the metal frame is fixed by a fixed structure, and the cut positions of the frame are marked by a etched structure.

[0033] Please see Figures 1-5 As one embodiment for fixing the metal frame to the entire device: a first mounting groove 12 is provided on the main frame 1, a movable block 3 is movably disposed in the first mounting groove 12, a first threaded rod 13 is provided on the main frame 1 in the first mounting groove 12, the first threaded rod 13 passes through the movable block 3, and the first threaded rod 13 is threadedly connected to the movable block 3, a connecting ring 14 is fixedly provided on both the movable block 3 and the fixed frame 4, a connecting rod 22 is detachably provided between the movable block 3 and the fixed frame 4, a connecting hole 15 is provided on both the connecting rod 22 and the connecting ring 14, and the connecting rod 22 and the connecting hole 15 on the connecting ring 14 are bolted together, a second mounting groove 16 is provided on the fixed frame 4, a second threaded rod 7 and a second fixed plate 6 are both disposed in the second mounting groove 16, the second threaded rod 7 is rotatably connected to the fixed frame 4, a first fixed plate 5 is fixedly disposed at the lower end of the fixed frame 4, the second threaded rod 7 passes through the second fixed plate 6, the second threaded rod 7 and the second fixed plate 6 are threadedly connected, and the second fixed plate 6 is slidably connected to the fixed frame 4;

[0034] Specifically, when positioning the cutting position of the frame, the frame is measured using external measuring tools to determine the approximate cutting position. The first threaded rod 13 is rotated, and through the threaded connection between the first threaded rod 13 and the moving block 3, as well as the two oppositely oriented threads on the first threaded rod 13, the moving block 3 and the fixed structure are moved closer or further apart, so that the cutting position of the frame is located between the two fixed frames 4. Depending on the thickness of the frame, the second threaded rod 7 is rotated, and through the threaded connection between the second threaded rod 7 and the second fixed plate 6, the second fixed plate 6 is moved, thereby changing the distance between the first fixed plate 5 and the second fixed plate 6. Thus, the metal frame is clamped by the first fixed plate 5 and the second fixed plate 6, thereby fixing the metal frame to the entire structure.

[0035] Please refer to Figure 1-5As one implementation method for marking the cutting position of the metal frame: two sliding columns 17 are fixedly provided on the moving plate 10; marking needles 11 are provided on the moving plate 10 and are threadedly connected to the moving plate 10; positioning holes 18 are provided on both the lifting block 9 and the mounting column 8; through holes 19 are provided on the lifting block 9 and are engaged with the sliding columns 17; the sliding columns 17 are slidably connected to the lifting block 9; a limiting piece 20 is detachably provided at the top of the sliding column 17 and is threadedly connected to the sliding column 17; multiple positioning holes 18 are provided on the mounting column 8 and are threaded inside; a positioning rod 21 is provided inside the positioning hole 18 on the lifting block 9 and is threadedly connected to the positioning hole 18.

[0036] Specifically, after the frame is fixed, the accurate cutting position is measured using external measuring tools. When marking the cutting position, the position of the lifting block 9 is changed by the sleeve connection between the lifting block 9 and the mounting column 8, and the cooperation between the different positioning holes 18 on the lifting block 9 and the mounting column 8, so that the marking needle 11 can easily approach the frame surface. After the position of the lifting block 9 is determined, the positioning rod 21 is rotated, and the positioning rod 21 is inserted into the positioning hole 18 on the mounting column 8 through the threaded connection between the positioning rod 21 and the positioning hole 18, so as to fix the position of the lifting block 9. After the fixation is completed, the tip of the marking needle 11 is made to contact the frame surface through the threaded connection between the marking needle 11 and the moving plate 10. The sliding column 17 is repeatedly pulled to move, so that the cutting position is marked on the frame by the marking needle 11.

[0037] In summary, when using it as a whole:

[0038] When positioning the cutting position of the frame, the frame is measured using external measuring tools to determine the approximate cutting position. The first threaded rod 13 is rotated, and through the threaded connection between the first threaded rod 13 and the moving block 3, as well as the two oppositely oriented threads on the first threaded rod 13, the moving block 3 and the fixed structure are moved closer or further apart, so that the cutting position of the frame is located between the two fixed frames 4. Depending on the thickness of the frame, the second threaded rod 7 is rotated, and through the threaded connection between the second threaded rod 7 and the second fixed plate 6, the second fixed plate 6 is moved, thereby changing the distance between the first fixed plate 5 and the second fixed plate 6. The metal frame is clamped by the first fixed plate 5 and the second fixed plate 6, thus fixing the metal frame to the entire structure.

[0039] After the frame is fixed, the accurate cutting position is measured using external measuring tools. When marking the cutting position, the position of the lifting block 9 is changed by the sleeve connection between the lifting block 9 and the mounting column 8 and the cooperation between the different positioning holes 18 on the lifting block 9 and the mounting column 8, so that the marking needle 11 can easily approach the frame surface. After the position of the lifting block 9 is determined, the positioning rod 21 is rotated and inserted into the positioning hole 18 on the mounting column 8 through the threaded connection between the positioning rod 21 and the positioning hole 18, thus fixing the position of the lifting block 9. After fixing, the tip of the marking needle 11 is made to contact the frame surface through the threaded connection between the marking needle 11 and the moving plate 10. The sliding column 17 is repeatedly pulled to move, thereby marking the cutting position on the frame through the marking needle 11.
