Description

Technical Field

[0001] This application relates to the field of angle iron drilling positioning mold technology, and more specifically, to an angle iron drilling anti-offset positioning mold. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. Angle steel is divided into equal-sided angle steel and unequal-sided angle steel. Equal-sided angle steel has two sides of equal width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. Equal-sided angle steel is often used in most production processes, but drilling is often required when applying angle steel.

[0003] A search revealed that the publication (announcement) number CN214769175U discloses "a tooling device for drilling angle iron, including an upper fixed plate and a lower fixed plate, with several fixed columns fixed between the upper and lower fixed plates for fixing the upper and lower fixed plates, and support seats symmetrically arranged on the upper surface of the lower fixed plate... This utility model solves the problem that traditional angle iron drilling requires manual marking and positioning, resulting in unstable dimensions, low accuracy, and waste of manpower and resources." However, this application requires pulling out two positioning pins when drilling the second hole in the angle iron, and then pushing the angle iron to move. When the drilled hole in the angle iron coincides with the positioning hole on the upper and lower fixed plates, two positioning pins are inserted to limit the angle iron. The operation is cumbersome, consumes a lot of time, and reduces work efficiency.

[0004] To address the aforementioned issues, this application provides an anti-offset positioning mold for drilling angle iron. Utility Model Content

[0005] One objective of this application is to provide an anti-deviation positioning mold for drilling angle iron, comprising an upper fixed plate and a lower fixed plate, four support columns fixedly connected between the upper and lower fixed plates, a partition plate fixedly connected in the middle of the upper and lower fixed plates, multiple support seats symmetrically fixedly connected to the top of the lower fixed plate, symmetrical sliding holes provided on the upper fixed plate, angle iron slidably connected between the partition plate and the multiple support seats, a drill sleeve slidably connected inside the sliding holes, two insertion holes symmetrically provided on the right end of the upper fixed plate, a matching limiting rod inserted into the insertion hole, a limiting plate fixedly connected to the top of the limiting rod at the top of the upper fixed plate, a limiting rod detachably connected to the limiting plate, a fixed plate slidably sleeved on the outer side of the limiting rod, and a limiting long rod symmetrically fixedly connected to the bottom end of the fixed plate.

[0006] Furthermore, the top of the limiting plate is provided with an installation groove, and the limiting rod is installed inside the installation groove. The limiting rod is arranged in a "U" shape.

[0007] Furthermore, the inner wall of the mounting groove is provided with a threaded groove, and the limiting rod is provided with a through hole. A limiting bolt is inserted into the through hole, and the limiting bolt is threaded into the inside of the threaded groove.

[0008] Furthermore, the length of the limiting rod is greater than the length of the limiting insert rod, and two rectangular holes are provided on the fixing plate, with the two ends of the limiting rod slidably inserted into the interior of the rectangular holes respectively.

[0009] Furthermore, a slider is slidably connected inside the sliding hole, and a circular hole is opened in the middle of the slider. The drill sleeve is fixedly inserted into the circular hole. Connecting plates are respectively provided on the upper and lower end faces of the upper fixing plate, and the two ends of the connecting plates are fixedly connected to the two drill sleeves respectively.

[0010] Furthermore, the inner wall of the sliding hole is symmetrically provided with sliding grooves, and the front and rear sides of the slider are slidably connected inside the sliding grooves.

[0011] Furthermore, a fixing frame is slidably connected to the outer side of the upper fixing plate. The fixing frame is arranged in a "U" shape. Both ends of the fixing frame are fixedly connected to the drill bushing. The fixing frame has threaded holes, and fixing bolts are inserted into the threads of the threaded holes.

[0012] The beneficial effects of this application are:

[0013] When drilling the first three holes, the user needs to manually operate the limiting rod to limit the angle iron. Before drilling the third hole, the limiting rod is inserted into the fixing plate, and the two limiting rods are respectively inserted into the two holes drilled in the first time, so that the left end of the limiting rod is located inside the mounting groove and fixed with the limiting bolt. Then the drilling of the third hole can begin.

[0014] After the third hole is drilled, when drilling all the subsequent holes, simply move the fixing plate upwards. The upward movement of the fixing plate will move the limiting rod, the limiting plate, and the two limiting rods upwards, so that the limiting rods move above the angle iron. Since the length of the limiting rod is greater than the length of the limiting rod, the limiting rod remains inserted inside the drilled hole. Then, move the fixing plate to the right outside the limiting rod. The rightward movement of the fixing plate will move the limiting rod and the angle iron to the right. When the limiting rod no longer coincides with the drilled hole on the angle iron, there is no need to apply an upward force to the fixing plate. Simply apply a rightward force from the left end of the fixing plate to push it forward. As the fixing plate moves, the limiting rod slides on the top of the angle iron. When the drilled hole on the angle iron coincides with the limiting rod during the movement of the angle iron, the limiting rod falls and inserts into the drilled hole, thus limiting the angle iron in conjunction with the action of the limiting rod.

[0015] In summary, this method enables rapid operation of pulling out the limit pin, moving the angle iron, and re-limiting the angle iron. Compared to existing technologies that require pulling out the positioning pin before moving the angle iron starting from the second drilling hole, and then re-inserting the positioning pin when the drilled hole on the angle iron coincides with the positioning hole, this method reduces operation time and improves work efficiency.

[0028] Example:

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5This application discloses an anti-deviation positioning mold for drilling angle iron, including an upper fixing plate 2 and a lower fixing plate 1. The upper surface of the upper fixing plate 2 is provided with scale lines for assisting in determining the drilling position. Four support columns 5 are fixedly connected between the upper fixing plate 2 and the lower fixing plate 1. A partition plate 13 is fixedly connected between the middle of the upper fixing plate 2 and the lower fixing plate 1. Multiple support seats 6 are symmetrically fixedly connected to the top of the lower fixing plate 1. Sliding holes 3 are symmetrically opened on the upper fixing plate 2. An angle iron 4 is slidably connected between the partition plate 13 and the multiple support seats 6. The bottom end face of the angle iron 4 is slidably connected to the top end face of the lower fixing plate 1. The two inner... The sidewalls are slidably connected to the top surface of the support base 6 and the side of the support base 6 near the partition plate 13, respectively. The opposite sides of the two angle irons 4 are slidably connected to the two sides of the partition plate 13, respectively. The inside of the sliding hole 3 is slidably connected to the drill sleeve 7. The right end of the upper fixed plate 2 has two symmetrically opened insertion holes. The insertion holes are fitted with matching limiting rods 21. The top of the upper fixed plate 2 is provided with a limiting plate 9 fixedly connected to the top of the limiting rods 21. A limiting rod 10 is detachably connected to the limiting plate 9. A fixed plate 12 is slidably sleeved on the outside of the limiting rod 10, and a limiting long rod 11 is symmetrically fixedly connected to the bottom end of the fixed plate 12.

[0030] Please see Figure 4 The top of the limiting plate 9 is provided with an installation groove 14, and the limiting rod 10 is installed inside the installation groove 14. The limiting rod 10 is set in a "U" shape. The inner wall of the installation groove 14 is provided with a threaded groove 15. The limiting rod 10 is provided with a through hole. A limiting bolt 16 is inserted into the through hole, and the limiting bolt 16 is threaded into the threaded groove 15. The left end of the limiting rod 10 is installed inside the installation groove 14, and then the limiting bolt 16 is inserted into the through hole and screwed into the threaded groove 15, thereby fixing the limiting rod 10.

[0031] Please see Figure 5 The length of the limiting rod 11 is greater than the length of the limiting rod 21, so that when the limiting rod 21 moves upward and leaves the drill hole, the limiting rod 11 is still inserted inside the drill hole. Two rectangular holes are opened on the fixing plate 12, and the two ends of the limiting rod 10 are slidably inserted into the rectangular holes respectively.

[0032] Please see Figure 2 and Figure 4A slider 19 is slidably connected inside the sliding hole 3. A circular hole is formed in the center of the slider 19, and the drill sleeve 7 is fixedly inserted into the circular hole. Connecting plates 18 are respectively provided on the upper and lower end faces of the upper fixing plate 2. The two connecting plates 18 are used to connect and fix the two drill sleeves 7 together, thereby enabling simultaneous fixing of the two drill sleeves 7 and improving work efficiency. The two ends of the connecting plates 18 are respectively fixedly connected to the two drill sleeves 7. Sliding grooves 17 are symmetrically formed on the inner wall of the sliding hole 3. The front and rear sides of the slider 19 are slidably connected inside the sliding grooves 17. The outer side of the upper fixing plate 2... The sliding connection includes a fixing frame 20, which is U-shaped. Both ends of the fixing frame 20 are fixedly connected to the drill sleeves 7. The upper and lower sides of the inner wall of the fixing frame 20 are slidably connected to the upper and lower end faces of the upper fixing plate 2, respectively. The fixing frame 20 has threaded holes, and fixing bolts 8 are inserted into the threads of the threaded holes. The distance between the drill sleeves 7 and the limiting rod 21 is determined by sliding along the scale lines set on the upper fixing plate 2. After determining the distance, the fixing bolts 8 are screwed onto the outside of the upper fixing plate 2, thereby fixing the two drill sleeves 7.

[0033] The implementation principle of this application embodiment is as follows: After determining the distance between the sliding drill sleeve 7 and the limiting rod 21 by setting the scale line on the upper fixed plate 2, the fixing bolt 8 is screwed on the outside of the upper fixed plate 2 to fix the two drill sleeves 7. Then, the angle iron 4 is sent from the left end of the upper fixed plate 2 to the space between the support base 6 and the partition plate 13, and the right end of the angle iron 4 resists the limiting rod 21, and then the drilling operation is performed.

[0034] After drilling, the limiting plate 9 is moved upward, thereby pulling out the two limiting rods 21 at the same time, pushing the angle iron 4 to the right. When the drilled hole coincides with the insertion hole on the upper fixed plate 2, the limiting rod 21 is inserted, and drilling is performed again. The two limiting rods 21 are pulled out, and the angle iron 4 is pushed to the right. When the second drilled hole coincides with the insertion hole on the upper fixed plate 2, the limiting rod 21 is inserted into the insertion hole and the drilled hole again. At this time, the limiting plate 9 is located on the top surface of the upper fixed plate 2. Then the limiting rod 10 is inserted into the fixed plate 12, and the two limiting rods 11 are respectively inserted into the two holes drilled in the first time, so that the left end of the limiting rod 10 is located inside the mounting groove 14 and fixed with the limiting bolt 16. Then the drilling operation continues.

[0035] After drilling is completed, to continue drilling, simply move the fixing plate 12 upwards. This upward movement of the fixing plate 12 causes the limiting rod 10, the limiting plate 9, and the two limiting rods 21 to move upwards, so that the limiting rods 21 move above the angle iron 4. Since the length of the limiting rod 11 is greater than the length of the limiting rod 21, the limiting rod 11 remains inserted inside the drilled hole. Then, move the fixing plate 12 to the right outside the limiting rod 10. This rightward movement of the fixing plate 12 causes the limiting rod 11 and the angle iron 4 to move to the right. When the movement reaches a certain point... When the limiting rod 21 is not aligned with the drilled hole on the angle iron 4 at a fixed distance, it is not necessary to apply an upward force to the fixing plate 12. It is only necessary to apply a rightward force from the left end of the fixing plate 12 to push the fixing plate 12 to move. When the fixing plate 12 moves, the limiting rod 21 slides on the top of the angle iron 4. When the drilled hole on the angle iron 4 aligns with the limiting rod 21 during the movement of the angle iron 4, the limiting rod 21 falls down and inserts into the inside of the drilled hole, thereby limiting the angle iron 4 in conjunction with the action of the limiting rod 11.

[0036] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
