Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure processing technology, and in particular to a drilling processing device for steel structure components. Background Technology
[0002] Steel structural components are widely used in modern industry, especially in construction, bridges, and machinery manufacturing. Their processing accuracy and efficiency directly affect the quality and performance of the overall structure. Drilling is one of the key processes in the manufacturing of steel structural components, used to create bolt holes, positioning holes, or other functional holes.
[0003] However, existing steel structure drilling equipment still faces several technical challenges in practical applications: 1. Splashing of metal fragments during drilling: During drilling, the friction between the drill bit and the metal material generates a large amount of high-temperature metal fragments. These fragments can easily splash onto operators, posing a safety hazard. 2. Insufficient use of cooling water and automated control: Since metal drilling generates significant frictional heat, failure to cool it down promptly can lead to accelerated drill bit wear, workpiece deformation, and even changes in material properties. Therefore, traditional drilling equipment typically uses a water-cooling system to reduce the temperature of the drill bit and workpiece by spraying water. However, most existing cooling systems are controlled by independent manual switches, requiring operators to turn on the water supply before drilling and manually turn it off after processing, making the operation cumbersome. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a drilling device for steel structural components.
[0005] The technical solution of this utility model is a drilling device for steel structural components, comprising: Mounting base, with sliding holes provided on the mounting base; The clamping mechanism includes two clamping blocks slidably mounted on the bottom end of the mounting base and a drive assembly for driving the two clamping blocks to move closer or further apart from each other; A sliding frame is slidably mounted on a mounting base. A U-shaped frame is connected to the sliding frame, and a lifting plate is slidably mounted inside the U-shaped frame. A handle that moves through the upper end of the U-shaped frame is connected to the lifting plate. The drilling mechanism includes a motor and a drill bit. The motor is mounted on the lifting plate, and the drill bit is mounted on the output shaft of the motor. The protective device includes an outer tube and an inner tube, both of which are located outside the drill bit. The outer tube is slidably installed on the outside of the bottom of the inner tube. A connecting frame is connected between the inner tube and the lifting plate, and an elastic component is connected between the inner tube and the outer tube. A water storage tank is located on the side of the sliding frame. A flexible hose is connected to the bottom of the water storage tank. A water inlet is opened at the upper end of the outer tube, and the other end of the flexible hose is connected to the water inlet. A vertical hole is opened at the lower part of the inner tube.
[0006] Preferably, two vertical rods are symmetrically arranged on the sliding frame, and a wedge block is provided at the upper end of the vertical rod. Mounting holes are provided at both ends of the sliding frame, and a first guide rod is provided inside the mounting hole. The two vertical rods are slidably mounted on the two first guide rods respectively, and a first spring is sleeved on each of the two first guide rods. Notches are provided at both ends of the lifting plate. Stop bars are connected to both ends of the top of the mounting base.
[0007] Preferably, the bottom of the vertical rod extends into the inner side of the sliding frame, and an anti-slip rubber pad is provided at the bottom of the vertical rod.
[0008] Preferably, the elastic component includes a second guide rod, a second spring, and a limiting block. Fixing blocks are connected to the outer walls of both the outer tube and the inner tube. The second guide rod movably passes through the upper fixing block, and both ends of the second guide rod are connected to the limiting block and the bottom fixing block, respectively. The second spring is sleeved and installed on the second guide rod.
[0009] Preferably, the drive assembly includes a bidirectional lead screw and a knob.

[0010] Preferably, an annular groove is provided at the bottom end of the inner tube, and a sealing ring is provided in the annular groove.
[0011] Compared with the prior art, the present invention has the following beneficial technical effects: When drilling into a steel structure, the bottom end of the outer tube first contacts the surface of the steel structure. As the drill bit is continuously driven to move downward, the second spring is compressed. When the drill bit contacts the steel structure, the surface of the steel structure is drilled through. The outer tube can protect the drill bit in a relatively enclosed space, thereby preventing the debris generated during the processing from flying outwards in all directions.
[0012] When the outer tube and the inner tube move relative to each other, that is, when the water inlet moves to the position of the vertical hole, the water stored inside the water tank flows to the surface of the drill bit through the hose, the water inlet and the vertical hole, realizing the function of automatic water discharge. The degree of automation is high, the water flowing out effectively reduces the generation of smoke and dust, and can also reduce the temperature of the drill bit and extend the service life of the drill bit.

[0019] Example 1 like Figures 1-5 As shown in the figure, the drilling device for steel structure components proposed in this embodiment includes a mounting base 1, a sliding frame 7, a water storage tank 11, a clamping mechanism, a drilling mechanism, and a protective device.
[0020] The mounting base 1 has a sliding hole 101; the clamping mechanism includes two clamping blocks 4 slidably mounted on the bottom end of the mounting base 1 and a drive assembly for driving the two clamping blocks 4 to move closer or further apart. The drive assembly includes a bidirectional lead screw 5 and a knob. The bidirectional lead screw 5 is rotatably mounted on the mounting base 1, and the knob is mounted on the end of the bidirectional lead screw 5. A guide slide rod 6 is provided at the bottom end of the mounting base 1. Both clamping blocks 4 are slidably mounted on the guide slide rod 6, and both clamping blocks 4 are threadedly connected to the bidirectional lead screw 5.
[0021] The sliding frame 7 is slidably mounted on the mounting base 1. A U-shaped frame 2 is connected to the sliding frame 7. A lifting plate 12 is slidably mounted inside the U-shaped frame 2. A handle 10 that moves through the upper end of the U-shaped frame 2 is connected to the lifting plate 12. The drilling mechanism includes a motor 8 and a drill bit 3. The motor 8 is mounted on the lifting plate 12, and the drill bit 3 is mounted on the output shaft of the motor 8.
[0022] The protective device includes an outer tube 161 and an inner tube 162. Both the outer tube 161 and the inner tube 162 are located outside the drill bit 3. The outer tube 161 is slidably installed on the bottom outer side of the inner tube 162. A connecting frame 9 is connected between the inner tube 162 and the lifting plate 12. An elastic component is connected between the inner tube 162 and the outer tube 161. The elastic component includes a second guide rod 19, a second spring 20, and a limiting block 21. Fixing blocks 18 are connected to the outer walls of both the outer tube 161 and the inner tube 162. The second guide rod 19 moves through the upper fixing block 18. The two ends of the second guide rod 19 are connected to the limiting block 21 and the bottom fixing block 18, respectively. The second spring 20 is sleeved on the second guide rod 19.
[0023] The water storage tank 11 is located on the side of the sliding frame 7. The bottom of the water storage tank 11 is connected to a flexible hose 111, and the top of the water storage tank 11 is connected to a water inlet pipe. A sealing cap is threaded onto the water inlet pipe. The top of the outer tube 161 has a water inlet hole, and the other end of the flexible hose 111 is connected to the water inlet hole. The bottom of the inner tube 162 has a vertical hole 1621. The bottom of the inner tube 162 has an annular groove, and a sealing ring 17 is installed in the annular groove.
[0024] In this embodiment, when drilling holes in the steel structure, the device is arranged according to... Figure 2 As shown, it is fixed to the steel structure; after determining the drilling position, push the handle 10 to move downward. The movement of the handle 10 drives the lifting plate 12 and the drilling mechanism to move downward. In the initial state, the bottom end of the outer tube 161 is located below the drill bit 3, so that the outer tube 161 first contacts the surface of the steel structure. When the drill bit 3 is continuously driven to move downward, the second spring 20 is compressed. When the drill bit 3 contacts the steel structure, the surface of the steel structure is drilled through by the drill bit 3. The outer tube 161 can protect the drill bit 3 in a relatively closed space, thereby preventing the debris generated during the processing from splashing outward.
[0025] When the outer tube 161 and the inner tube 162 move relative to each other, that is, when the water inlet moves to the position of the vertical hole 1621, the water stored inside the water tank 11 flows to the surface of the drill bit 3 through the hose 111, the water inlet, and the vertical hole 1621, realizing the automatic water discharge function. The automation level is high, the water flowing out effectively reduces the generation of smoke and dust, and can also reduce the temperature of the drill bit 3 and extend the service life of the drill bit 3. When the outer tube 161 is separated from the steel structure, the outer tube 161 automatically resets under the elastic force of the second spring 20. At this time, the water inlet is blocked by the sealing ring 17 at the bottom of the inner tube 162, which can prevent the water inside the water tank 11 from overflowing. In addition, it should be added that tap water can also be used in this technical solution. One end of the hose 111 can be connected to a tap.
[0026] Example 2 like Figure 1 and Figure 3As shown, the drilling device for steel structural components proposed in this embodiment differs from that in Embodiment 1. In this embodiment, two vertical rods 13 are symmetrically arranged on the sliding frame 7. A wedge block 131 is provided at the upper end of the vertical rod 13. Mounting holes 701 are provided at both ends of the sliding frame 7. A first guide rod 14 is provided inside the mounting hole 701. The two vertical rods 13 are slidably mounted on the two first guide rods 14. A first spring 15 is sleeved on each of the two first guide rods 14. Notches 121 are provided at both ends of the lifting plate 12. Stop bars 22 are connected to both ends of the top of the mounting base 1. The bottom of the vertical rod 13 extends into the inner side of the sliding frame 7, and an anti-slip rubber pad is provided at the bottom end of the vertical rod 13.
[0027] In this embodiment, when the lifting plate 12 moves downward, after the upper end of the wedge block 131 moves to the inside of the notch 121, the inclined surface of the wedge block 131 contacts the side of the lifting plate 12. As the lifting plate 12 continues to move, it pushes the vertical rods 13 on both sides away from each other. At this time, the first spring 15 is in a compressed state. After the vertical rod 13 is displaced, the anti-slip rubber pad at its bottom end abuts against the inner wall of the stop rod 22, thereby increasing the moving resistance of the sliding frame 7 and preventing the sliding frame 7 from generating a large displacement during the drilling process, thereby improving the processing quality of the device.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
