Description

Technical Field

[0001] This utility model relates to the technical field of steel structure processing equipment, and in particular to a drilling device for steel structures with a fixed structure. Background Technology

[0002] Drilling equipment for steel structures is a mechanized tool specifically designed for processing holes in steel structure materials. It achieves the processing requirements of different hole sizes through precise positioning and efficient cutting. The equipment is usually composed of a power system, cutting mechanism, positioning device and frame. It is widely used in the processing of components in steel structure buildings (bridges, factories, high-rise buildings), shipbuilding, and mechanical equipment, and is a key piece of equipment to ensure the connection accuracy and assembly quality of steel structures.

[0003] Existing technologies, such as the utility model patent with publication number CN221818000U, disclose a rapid positioning and drilling device for steel structures. This patent uses a main base plate, with a base support plate fixedly connected to the bottom of the main base plate. A second motor is fixedly connected to the top of the base support plate, and a first linkage rod is fixedly connected to the top of the second motor. A connecting piece is rotatably connected to the top of the first linkage rod, and the main base plate is fixedly connected to the top of the connecting piece. This addresses the problem that drilling devices cannot adapt to steel structures of different sizes, which limits their ability to handle workpieces of different dimensions. This results in a limited working range, requiring the use of multiple devices or frequent changes and adjustments, increasing the complexity and cost of the work. It also requires more time and effort to adjust, replace fixtures, or reset equipment parameters, reducing work efficiency and increasing production cycle and cost.

[0004] Existing steel structure drilling equipment, such as the one mentioned above, uses adjustable clamps to improve work efficiency and accommodate steel structures of different specifications. While adjustable clamps can adapt to most conventional steel structures, they have significant support and clamping defects when dealing with special cross-section profiles such as I-beams. This directly increases the risk of deformation at the drilling location. I-beams have an "I"-shaped cross-section, consisting of an upper flange, a lower flange, and a web. Drilling operations are mostly concentrated at specific locations on the upper and lower flanges.

[0005] Its clamping structure is a "two-point" design, which can only clamp the edge of the flange of the I-beam by adjusting the distance between the jaws. The clamping point is located on the outer side of the flange, while the drilling position is located in the middle of the flange or near the web, with a lateral distance of 50-100mm between the two.

[0006] This misalignment prevents the clamping force from being effectively transmitted to the drilling area. When the drill bit applies axial cutting force to the flange, the middle of the flange will bend and deform away from the drill bit due to the lack of direct support. This is especially true for thin-flange I-beams with a thickness of ≤10mm, where the deformation of a single drilling operation can reach 0.5-1mm, far exceeding the allowable accuracy range of 0.1mm for steel structure installation, leading to problems such as hole position displacement or out-of-tolerance hole diameter. Utility Model Content

[0033] In this embodiment, the first telescopic sleeve 710 and the second telescopic sleeve 711 can protect the bidirectional lead screw 75 to ensure the stability and safety of the bidirectional lead screw 75 during operation.

A sprocket 87 is fixedly connected to the surface of the first lead screw 81. A storage cavity is opened on the upper surface of the machine body 1. The sprocket 87 is located inside the storage cavity. A chain 88 is installed on the surface of the sprocket 87. The chain 88 is located inside the storage cavity.

[0039] Specifically, the surface of the baffle 811 is provided with a threaded hole, and the locking bolt 86 is threadedly connected to the inner wall of the threaded hole.

[0040] In this embodiment, the first lead screw 81, bevel gear 82, and bevel gear 84 can be protected by the cooperation of the baffle 811 and the assembly frame 71 to ensure the stability of the above structure during transmission.

[0041] Working principle: During processing, the I-beam 6 is placed in the clamping area of ​​the equipment. After placement, the clamping device 7 is used to clamp the I-beam 6. After the clamping operation is completed, the drive mechanism 3 and the motor are turned on by the control switch 2. The drive mechanism 3 and the motor are powered on and work. The drive mechanism 3 drives the motor to move downward. The motor drives the drill bit 5. At this time, the downward-moving motor approaches the I-beam 6 and, together with the drill bit 5, drills a hole on the surface of the I-beam 6 when it contacts the I-beam 6.

[0042] When the I-beam 6 is placed, turn on the switch of motor 4. Motor 4 drives the double-acting lead screw 75. The double-acting lead screw 75 engages with the transmission frame 76 through threads. Under the action of the double-acting lead screw 75, the two transmission frames 76 move towards each other, pushing the clamping plate 77 and the support frame 78 closer to the I-beam 6. During the movement, the two transmission frames 76 pull the first telescopic sleeve 710 and squeeze the second telescopic sleeve 711. As the clamping plate 77 and the support frame 78 approach the I-beam 6, they gradually clamp the I-beam 6. When the clamping plate 77 and the support frame 78 have clamped the I-beam 6, the support frame 78 can support the drilling position of the I-beam 6. Then, start the drive. Mechanism 3 and motor 4, together with drill bit 5, drill holes in I-beam 6 according to the above steps; after drilling is completed, drill bit 5 is withdrawn. After drill bit 5 is withdrawn and reset, drive mechanism 3 and motor 4 are turned off. After drive mechanism 3 and motor 4 are turned off, clamping device 7 is opened, I-beam 6 is taken out, and the position of I-beam 6 can be changed or I-beam 6 can be replaced as needed. By setting clamping device 7, I-beam 6 of different specifications can be clamped at the same time, and the flange part of I-beam 6 can be supported to ensure that the drilling position on the flange has structural support, thereby reducing the probability of deformation at the drilling position of I-beam 6 and improving the drilling quality of drilling equipment;

[0043] When the support frame 78 is not in contact with the inner side of the upper flange of the I-beam 6 in its placed state, use a tool to loosen the locking bolt 86. At this time, the operating lever 83 is unlocked. Rotating the operating lever 83 rotates the bevel gear 84, which meshes with the bevel gear 82. The bevel gear 82 drives the first lead screw 81 to rotate, which in turn rotates the sprocket 87. The sprocket 87, in conjunction with the chain 88, drives the second sprocket 810, which in turn drives the second lead screw 89 to rotate. Subsequently, the first lead screw 81 and the second lead screw 89 rotate synchronously and respectively mesh with the lifting frame 72 on their own surfaces. The lifting frame 72 is activated by the first lead screw 81 and the second lead screw 89. Push the connecting frame 73 upwards. The connecting frame 73 drives the motor 74, the double lead screw 75, the transmission frame 76, the clamping plate 77, and the support frame 78 to move in the specified direction. During the movement, the support frame 78 moves upwards and approaches the upper flange of the I-beam 6. When the support frame 78 abuts against the upper flange, it remains in this state. Use a tool to re-tighten the locking bolt 86. The locking bolt 86, together with the baffle 811 and the positioning frame 85, locks the operating rod 83, thereby completing the height adjustment operation of the clamping device 7. By setting the auxiliary device 8, the support structure of the clamping device 7 can effectively support the I-beam 6, so as to ensure the support effect of the clamping device 7 on the I-beam 6.

[0044] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. In addition, the transmission structures such as sprockets and chains mentioned in the article can be lubricated in a conventional known way, and the tension of sprockets and chains can be adjusted in a conventional known way.
