Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to an angle steel drilling machine. Background Technology

[0002] Angle steel is a type of long steel bar with two perpendicular sides, forming an "L" shaped cross-section, commonly known as angle iron. It possesses excellent load-bearing capacity and stability, making it suitable for various structural components and connectors. Angle steel can be categorized into equal-sided angle steel and unequal-sided angle steel based on the length of its two sides. Equal-sided angle steel has two sides of equal length, making it suitable for manufacturing symmetrical structures; unequal-sided angle steel has two sides of unequal length, allowing for customization to meet specific needs and offering greater flexibility.

[0003] During the production and processing of angle steel, drilling is required to drill holes in the angle steel for installation. Because angle steel is L-shaped, a clamping structure is needed to fix it during drilling. After drilling one side of the angle steel, the clamping structure must be released, the angle steel's orientation and position adjusted, and finally, the other side of the angle steel is drilled. However, the existing clamping structure is relatively complex and the operation is cumbersome, resulting in low processing efficiency. Furthermore, the drilling process generates a large amount of flying metal shavings, which can easily splash onto workers or into their eyes, causing accidental injury. Utility Model Content

[0004] The purpose of this utility model is to provide an angle steel drilling machine to address the shortcomings of the existing technology and solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An angle steel drilling machine includes an operating table in L-shape. A groove is formed on the front of the operating table, and a lead screw is movably mounted within the groove. A motor is mounted on the top surface of the operating table, and the motor is connected to the lead screw via a coupling. A T-shaped seat is fixedly connected to the lead screw via a slider. A groove is formed on the front of the T-shaped seat, and a second lead screw is movably mounted within the groove. A third motor is mounted on the left side of the T-shaped seat, and the third motor is connected to the second lead screw via a coupling. The second lead screw is connected to a movable seat via a slider. The second motor is mounted on the upper surface of the movable seat. The output shaft of the second motor passes through the movable seat and is detachably mounted with a drill bit. An angle steel limiting assembly is mounted in the middle of the operating table.

[0007] The angle steel limiting assembly includes a square base and two fixing plates. The two fixing plates are located on the left and right sides of the square base and are fixedly installed on the operating table. Rotating rods are fixedly connected to both sides of the square base. The rotating rods on both sides are movably connected to the fixing plates. The rotating rod on the left side protrudes from the fixing plate and is fixedly connected to a handle. The rotating rod on the right side protrudes from the fixing plate and is movably inserted into a limiting plate. Several interconnected circular holes are opened on the upper surface and front side of the square base, and two limiting assemblies are movably fitted on the square base.

[0008] As a preferred embodiment of the angle steel drilling machine, both of the limiting components include a positioning sleeve, and a fixing bolt is threadedly connected to the upper surface of the positioning sleeve. The fixing bolt passes through the lower end of the positioning sleeve and is fixedly connected to a rubber block.

[0009] As a preferred embodiment of the angle steel drilling machine, a sliding rod is fixedly connected to the outer surface of the right-side fixing plate. The sliding rod is slidably connected to the limiting plate, and an anti-detachment block is fixedly connected to one end of the sliding rod that protrudes from the limiting plate.

[0012] As a preferred embodiment of the angle steel drilling machine, the height of the protective plate is greater than the length of the drill bit.

[0013] The beneficial effects of this utility model are:

[0014] (1) The angle steel drilling machine of this utility model adopts the structural design of angle steel limiting component. When in use, the inner side of the L-shaped angle steel is tightly attached to the outer surface of the square seat, and the angle steel is positioned by the limiting component.

[0029] like Figures 1 to 6 As shown, this utility model provides an angle steel drilling machine, including an operating table 1, which is L-shaped. A groove 2 is provided on the front of the operating table 1, and a lead screw is movably installed in the groove 2. A motor 4 is installed on the top surface of the operating table 1, and the motor 4 is connected to the lead screw via a coupling. A T-shaped seat 3 is connected to the lead screw via a slider. A groove is provided on the front of the T-shaped seat 3, and a lead screw 2 is movably installed in the groove. A motor 3 9 is installed on the left side of the T-shaped seat 3, and the motor 3 9 is connected to the lead screw 2 via a coupling. The lead screw 2 is connected to a movable seat 5 via a slider. A motor 2 7 is installed on the upper surface of the movable seat 5, and the output shaft of the motor 2 7 passes through the movable seat 5 and is detachably mounted with a drill bit 8. The middle part of the operating table 1... An angle steel limiting component 6 is installed, and the L-shaped angle steel can be placed in the angle steel limiting component 6 for positioning. Motor 1 4 drives the lead screw 1 to rotate, which can make the T-shaped seat 3 move downward. Motor 2 7 drives the drill bit 8 to rotate, which can drill holes in the angle steel. After one hole is processed, motor 1 4 drives the T-shaped seat 3 to rise, and at the same time, motor 3 9 drives the lead screw 2 to rotate, so that the moving seat 5 moves to the position of other holes. Then, motor 1 4 drives the T-shaped seat 3 to move downward again, so that the drill bit 8 contacts the angle steel again, thereby performing drilling operations on different positions of the angle steel. The operating table 1 or the moving seat 5 can be equipped with a structure used in the prior art for cooling the drill bit 8 and the angle steel during drilling.

[0030] Specifically, the angle steel limiting component 6 in this embodiment includes a square base 64 and two fixing plates 61. The two fixing plates 61 are located on the left and right sides of the square base 64 and are fixedly installed on the operating table 1. Rotating rods 63 are fixedly connected to both sides of the square base 64. The rotating rods 63 on both sides are movably connected to the fixing plates 61. Several interconnected circular holes 65 are opened on the upper surface and front surface of the square base 64. Two limiting components 66 are movably sleeved on the square base 64. The rotating rod 63 on the left protrudes from the fixing plate 61 and is fixedly connected to a handle 67. The rotating rod 63 on the right protrudes from the fixing plate 61 and is movably inserted into a limiting plate 62. At the same time, a sliding rod 68 is fixedly connected to the outer surface of the fixing plate 61 on the right side. The sliding rod 68 is slidably connected to the limiting plate 62, and an anti-detachment block is fixedly connected to one end of the sliding rod 68 protruding from the limiting plate 62 to prevent the limiting plate 62 from detaching.

[0031] Preferably, in this embodiment, a square plug 631 is fixedly connected to the rotating rod 63 on the right side, and a square hole 621 is provided on the limiting plate 62. The square plug 631 is inserted into the square hole 621 to limit the rotating rod 63.

[0032] Specifically, in this embodiment, both limiting components 66 include a positioning sleeve 661. The upper surface of the positioning sleeve 661 is threaded with a fixing bolt 662. The fixing bolt 662 passes through the lower end of the positioning sleeve 661 and is fixedly connected to a rubber block 663.

[0033] When positioning the L-shaped angle steel, first place the inner side of the angle steel tightly against the outer surface of the square base 64. At this time, the vertical outer surface of the angle steel should be lower than the height of the positioning sleeve 661. The operator then moves the limiting component 66 to the appropriate position, allowing the positioning sleeve 661 to be fitted onto the outside of the angle steel. The fixing bolt 662 is rotated, causing the rubber block 663 to contact and tighten against the surface of the angle steel. Simultaneously, the limiting plate 62 is pushed, allowing the square insert 631 to enter the square hole 621, thus positioning the rotating rod 63 and preventing shaking during drilling. When drilling is required on the other side of the angle steel, the operator simply pulls the limiting plate 62 to separate the square insert 631 from the square hole 621. Then, the handle 67 is rotated, causing the rotating rod 63 and the square seat 64 to rotate, moving the other side of the angle steel to the top. The limiting plate 62 is then pulled again to re-insert the square insert 631 into the square hole 621, repositioning it, and drilling can continue. The limiting structure in this embodiment is simple and quick to install and disassemble, effectively improving the processing efficiency of the angle steel. Furthermore, the design of the rubber block 663 effectively protects the surface of the angle steel, preventing indentations during tightening.

[0034] More specifically, in this embodiment, the front of the movable seat 5 is threadedly connected to a fixing bolt 51, and a top block 52 is fixedly sleeved on the outer surface of the fixing bolt 51. A circular block 53 is also movably sleeved on the rear side of the fixing bolt 51 and a protective plate 54 is fixedly installed on the circular block 53. The height of the protective plate 54 is greater than the length of the drill bit 8, and the protective plate 54 is made of transparent material.

[0035] During drilling, the operator can loosen the fixing bolt 51 to separate the top block 52 from the circular block 53. At this time, the protective plate 54 can be rotated to face downwards, thereby preventing iron filings generated by the angle steel during drilling from flying around and providing protection for the operator. When the protective plate 54 is not needed, the operator can rotate the protective plate 54 to the top and simultaneously tighten the fixing bolt 51, so that the top block 52 presses the circular block 53 tightly, thereby positioning the protective plate 54.

[0036] Working principle and usage process of this utility model:

[0037] When using this angle steel drilling machine, first, the inner side of the angle steel is pressed tightly against the outer surface of the square base 64. The operator moves the limiting component 66 to the appropriate position so that the positioning sleeve 661 covers the outer side of the angle steel. At the same time, the fixing bolt 662 is rotated to press against the surface of the angle steel and position the angle steel. Then, the limiting plate 62 is pushed so that the square insert 631 is inserted into the square hole 621 to position the rotating rod 63 and limit the position of the square base 64 to prevent shaking during drilling.

[0038] When drilling is required on the other side of the angle steel, the operator only needs to pull the limiting plate 62 to separate the square insert 631 from the square hole 621, and then turn the handle 67. The handle 67 will drive the rotating rod 63 and the square seat 64 to rotate, so that the other side of the angle steel faces upward. Then, the operator only needs to push the limiting plate 62 again to re-insert the square insert 631 into the square hole 621, and then the hole can be drilled.

[0039] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
