Description

Technical Field

[0001] This utility model belongs to the field of stainless steel processing technology, and in particular relates to a hole-opening device for stainless steel square tubes. Background Technology

[0002] Stainless steel square tubing is commonly used in the processing of stainless steel windows. During the processing of the tubing, holes need to be drilled according to the usage requirements so that vertical tubing can be inserted and welded at the connection points.

[0003] When drilling holes in existing square tubes, the tubes are first marked with their positions, and then drilling is performed using a drilling machine. Because stainless steel is relatively hard and has a smooth surface, deviation can occur during drilling, causing the tube to lift up and increasing the difficulty of drilling. To address this, we propose a drilling device for stainless steel square tubes that avoids deviation during drilling, thus solving the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a hole-opening device for stainless steel square tubes, which stabilizes the square tube during hole opening to prevent displacement of the opening, thereby solving the aforementioned technical problems.

[0022] In the following description, embodiments of the opening device for stainless steel square tubes according to the present invention will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-4 This invention illustrates an embodiment of a hole-opening device for stainless steel square tubes, comprising a base 1, a movable frame 2 that moves back and forth on the top of the base 1, a left and right movable support 3 on the top of the front of the movable frame 2, a drive motor 4 that slides up and down on the front of the support 3, a drill bit 5 fixedly connected to the output shaft of the drive motor 4, an electric telescopic rod 6 fixedly connected to the rear side of the top of the base 1, a limit plate 7 fixedly connected to the telescopic end of the electric telescopic rod 6, the bottom of the limit plate 7 being slidably connected to the top of the base 1, a limit plate 8 fixedly connected to the front side of the top of the base 1, a lower limit seat 9 fixedly connected to the side opposite to the limit plate 7 and the limit plate 8 and higher than the top end face of the base 1, and a slidably adjustable upper limit structure on the top of the limit plate 8.

[0025] The upper limit structure includes a sliding groove 10 formed on the front of the second limit plate 8. A sliding block 11 is slidably connected to the inner surface of the sliding groove 10. A locking seat 12 is fixedly connected to the side of the sliding block 11 away from the sliding groove 10. A threaded rod 13 is threadedly connected to the top of the inner cavity of the locking seat 12. A limit block 14 is fixedly connected to the bottom of the threaded rod 13. Multiple threaded holes 15 are formed on the inner surface of the sliding groove 10. Threaded bolts 16 are threadedly connected to the inner surface of the threaded holes 15. The threaded bolts 16 pass through the sliding block 11 and extend to the inner surface of the threaded holes 15. The sliding groove 10 passes through the end face of the second limit plate 8. The sliding groove 10 is T-shaped. The sliding block 11 and the inner surface of the sliding groove 10... The sliding block 11 slides on the inner surface of the sliding groove 10. When it slides to the required limiting position, the threaded bolt 16 passes through the sliding block 11 and is threadedly connected to the corresponding threaded hole 15. After the thread is tightened, the threaded rod 13 rotates on the inner surface of the locking seat 12, thereby driving the limiting block 14 to move, thus limiting the top position of the square tube. By setting the sliding groove 10 to pass through the end face of the limiting plate 8, the sliding groove 10 is T-shaped. The sliding block 11 slides in accordance with the inner surface of the sliding groove 10. Different locking seats 12 can be used for different square tubes to meet the limiting requirements of different square tubes.

[0026] The square tube is placed on the lower limit seat 9 connected to the second limit plate 8. With manual assistance, the first limit plate 7 is moved by the electric telescopic rod 6, thereby moving the lower limit seat 9 connected to the first limit plate 7. This allows the lower limit seat 9 to support the bottom of the tube. The first limit plate 7 and the second limit plate 8 limit the front and rear ends of the tube. At the same time, the upper limit structure can be moved as needed to limit the upper end of the square tube. The position is then adjusted by the drive motor 4. By setting up the above structure, the square tube can be stabilized when drilling holes, thereby preventing the holes from shifting.

[0027] Example 2:

[0028] Figure 1-4This invention illustrates an embodiment of a hole-opening device for stainless steel square tubes, comprising a base 1, a movable frame 2 that moves back and forth on the top of the base 1, a left-right movable support 3 on the top of the front of the movable frame 2, a drive motor 4 that slides up and down on the front of the support 3, a drill bit 5 fixedly connected to the output shaft of the drive motor 4, an electric telescopic rod 6 fixedly connected to the rear side of the top of the base 1, a limit plate 7 fixedly connected to the telescopic end of the electric telescopic rod 6, a guide groove on the top of the base 1, the inner surface of the guide groove slidingly connected to the bottom of the limit plate 7, the movement of the limit plate 7 can be limited and guided by the guide groove slidingly connected to the bottom of the limit plate 7, the bottom of the limit plate 7 slidingly connected to the top of the base 1, a second limit plate 8 fixedly connected to the front side of the top of the base 1, a lower limit seat 9 fixedly connected to the side opposite to the limit plate 7 and the second limit plate 8 and higher than the top end face of the base 1, and an upper limit structure that can be slidably adjusted on the top of the second limit plate 8.

[0029] Working principle: When using this utility model, the square tube is placed on the lower limit seat 9 connected to the second limit plate 8. With manual assistance, the electric telescopic rod 6 drives the first limit plate 7 to move, thereby moving the lower limit seat 9 connected to the first limit plate 7. This allows the lower limit seat 9 to support the bottom of the tube, and the first limit plate 7 and the second limit plate 8 limit the front and rear ends of the tube. At the same time, the sliding block 11 slides on the inner surface of the sliding groove 10 as needed. When it slides to the required limit position, the threaded bolt 16 passes through the sliding block 11 and is threadedly connected to the corresponding threaded hole 15. After the thread is tightened, the threaded rod 13 rotates on the inner surface of the locking seat 12, thereby driving the limit block 14 to move and limit the upper end of the square tube. Then, the position is adjusted by the drive motor 4, which stabilizes the square tube when it is drilled, thus preventing the drilling from shifting.
