Description

Technical Field

[0001] This utility model belongs to the field of steel structure installation technology, and specifically relates to a drilling machine for installation holes in steel structures. Background Technology

[0002] In the field of steel structure installation, drilling is an indispensable and important process in the processing and assembly of steel structures. With the increasing demand for steel structures in the construction industry, the efficiency and accuracy of drilling operations directly affect the installation quality and construction progress of steel structures.

[0003] A search revealed a Chinese utility model patent (publication number: CN216461868U) that discloses a radial drilling machine for producing steel structure doors. The machine includes a door frame fixing mechanism for fixing the steel structure door, a bottom adjustment mechanism for fine adjustment, and a drilling machine adjustment mechanism for processing the steel structure door. The door frame fixing mechanism is installed at the upper end of the bottom adjustment mechanism, and a lifting mechanism is provided at the rear end of the door frame fixing mechanism. The drilling machine adjustment mechanism is installed on the lifting mechanism, and a linkage mechanism is connected to the power end of the door frame fixing mechanism.

[0004] The aforementioned patent utilizes a door frame fixing mechanism and a linkage mechanism to quickly and stably move excessively long steel structure doors while ensuring their stability and improving work efficiency. By using a lifting mechanism and a drilling rig adjustment mechanism, holes can be drilled into the steel structure door at different angles. However, during the drilling process, debris generated during drilling will remain inside the mounting holes of the steel structure. If the iron filings at the hole opening are not dealt with in time, they will not only affect the connection accuracy and appearance quality of the components. Utility Model Content

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-4This utility model provides a drilling machine for installation holes in steel structures. Its core lies in achieving high-precision drilling through the coordinated operation of a three-axis motion mechanism 2, a drilling mechanism 3, and a chip removal mechanism 4. It effectively solves the problem of metal chip accumulation during drilling affecting construction quality and efficiency. The following will be discussed in conjunction with the attached... Figure 1 To be continued Figure 4 The specific structure and component numbers are described, and the specific embodiments of this utility model are described in detail.

[0024] like Figure 1 As shown, the overall structure of this utility model includes a base plate 1, a three-axis motion mechanism 2, a drilling mechanism 3, and a chip suction mechanism 4. The base plate 1 serves as the basic support for the entire device, and its bottom is equipped with four self-locking casters 5, which are distributed at the four corners of the bottom of the base plate 1. Each self-locking caster 5 is equipped with a locking device, which can be quickly fixed by manual or automatic locking after the equipment is moved into place, thereby ensuring the stability of the equipment during the drilling process. This design gives the equipment high mobility and is suitable for various construction scenarios, especially in construction sites where the equipment position needs to be frequently adjusted, which has significant advantages.

[0025] The three-axis motion mechanism 2 is mounted on the top of the base plate 1 and consists of a first moving component, a second moving component, and a third moving component, which respectively realize precise movement in the X, Y, and Z axes. Figure 2 As shown, the first moving component includes a first base 21, which is fixedly connected to the top of the base plate 1. A first servo motor 22 is fixedly installed on its rear side. The output end of the first servo motor 22 is connected to a first lead screw 23 via a coupling. A first moving block 25 is threadedly connected to the outer wall of the first lead screw 23. A first guide block is provided on the outer side of the first moving block 25. A first guide groove 24 matching the first guide block is opened inside the first base 21. The first guide block is slidably connected in the first guide groove 24. The first servo motor 22 drives the first lead screw 23 to rotate, so that the first moving block 25 moves linearly along the X-axis. The design of the first guide groove 24 not only improves the motion accuracy of the first moving block 25, but also avoids the offset problem caused by excessive load.

[0026] The second moving component is located on top of the first moving component and includes a second base 26. The second base 26 is fixedly connected to the top of the first moving block 25, and a second servo motor 27 is fixedly installed on one side of it. The output end of the second servo motor 27 is connected to the second lead screw 28 through a coupling. The outer wall of the second lead screw 28 is threadedly connected to the second moving block 29. A second guide block is provided on the outer side of the second moving block 29. A second guide groove 210 matching the second guide block is opened inside the second base 26. The second guide block is slidably connected in the second guide groove 210. The second lead screw 28 is driven to rotate by the second servo motor 27, so that the second moving block 29 moves linearly along the Y-axis. The design principle of the second moving component is the same as that of the first moving component, but the direction of movement is perpendicular to the first moving component, thereby realizing two-dimensional precise positioning in the XY plane.

[0027] The third moving component is located on top of the second moving component and includes a column 211. The column 211 is fixedly connected to the top of the second moving block 29, and a third servo motor 212 is fixedly installed on its top. The output end of the third servo motor 212 is connected to the third lead screw 213 through a coupling. A lifting block 214 is threadedly connected to the outer wall of the third lead screw 213. A third guide block is provided on the outer side of the lifting block 214. A third guide groove 215 matching the third guide block is opened inside the column 211. The third guide block is slidably connected in the third guide groove 215. The third servo motor 212 drives the third lead screw 213 to rotate, so that the lifting block 214 moves linearly along the Z-axis. The design of the third moving component enables the drilling mechanism 3 to perform precise positioning operations in three-dimensional space, meeting the drilling needs of steel structures of different specifications.

[0028] like Figure 3 As shown, the drilling mechanism 3 is located in front of the three-axis motion mechanism 2 and includes a connecting plate 31, a drilling motor 32, a connecting shaft 33, and a drill bit 34. The connecting plate 31 is fixedly connected to the front of the lifting block 214. The drilling motor 32 is detachably connected to the front of the connecting plate 31 by mounting screws. The output end of the drilling motor 32 is connected to the connecting shaft 33 by a coupling. The front end of the connecting shaft 33 is detachably connected to the drill bit 34 by mounting screws. The drilling mechanism 3 can complete high-precision drilling operations on steel structures under the drive of the three-axis motion mechanism 2. In particular, the drill bit 34 adopts a modular design and can be quickly replaced according to different drilling needs. For example, it can be replaced with drill bits 34 of different diameters or materials to adapt to drilling tasks of different specifications. This modular design not only improves the adaptability of the equipment but also significantly improves drilling efficiency.

[0029] The chip-collecting mechanism 4 is located outside the drilling mechanism 3 and is used to collect and remove debris and iron filings generated during the drilling process, such as… Figure 4As shown, the chip suction mechanism 4 includes a mounting frame 41, which is fixedly connected to the front side of the three-axis motion mechanism 2. A first electric push rod 42 and a second electric push rod 44 are fixedly connected to the front side of the mounting frame 41. There are two first electric push rods 42 and two second electric push rods 44, and the two first electric push rods 42 are located between the two second electric push rods 44. A first electric magnetic disk 43 is fixedly connected to the output end of the first electric push rod 42, and a second electric magnetic disk 45 is fixedly connected to the output end of the second electric push rod 44. When the first electric magnetic disk 43 and the second electric magnetic disk 45 are energized, they generate a magnetic field to attract iron filings and other metal debris generated during drilling. The extension length of the first electric push rod 42 and the second electric push rod 44 can be independently adjusted, so that the first electric magnetic disk 43 and the second electric magnetic disk 45 are close to the steel structure surface to improve the adsorption effect. In particular, the extension length of the first electric push rod 42 and the second electric push rod 44 can be precisely adjusted by the control system to adapt to steel structure surfaces of different thicknesses or shapes.

[0030] In actual operation, the steel structure to be processed is first placed in the working area above the base plate 1. The equipment is moved to a suitable position and locked using the self-locking casters 5. The three-axis motion mechanism 2 is then activated. The first servo motor 22 drives the first lead screw 23 to rotate, causing the first moving block 25 to move along the X-axis to the target position. The second servo motor 27 drives the second lead screw 28 to rotate, causing the second moving block 29 to move along the Y-axis to the target position. The third servo motor 212 drives the third lead screw 213 to rotate, causing the lifting block 214 to move along the Z-axis to the target height. The coordinated operation of the three-axis motion mechanism 2 achieves precise three-dimensional spatial positioning of the drilling position. Subsequently, the process is started. The drilling motor 32 drives the connecting shaft 33 to rotate, which in turn drives the drill bit 34 to drill holes in the steel structure. During this process, the chip suction mechanism 4 is activated simultaneously. The first electric push rod 42 and the second electric push rod 44 extend to a suitable length according to preset parameters, so that the first electric magnetic disk 43 and the second electric magnetic disk 45 are close to the surface of the steel structure. After the first electric magnetic disk 43 and the second electric magnetic disk 45 are energized, they generate a magnetic field, which adsorbs the metal chips generated during the drilling process, preventing the accumulation of chips from affecting the drilling accuracy and the quality of the components. After the drilling is completed, the power supply to the first electric magnetic disk 43 and the second electric magnetic disk 45 is disconnected. The metal chips lose their magnetic attraction and fall off, and are collected for subsequent processing.

[0031] The technical solution of this utility model has shown significant advantages in practical applications. For example, in the construction of a large steel structure factory, this utility model was used to drill installation holes in steel structure beams and columns. Through the precise positioning function of the three-axis motion mechanism 2, and the chip suction mechanism 4, the metal chips generated during the drilling process were effectively removed, avoiding stress concentration and steel corrosion caused by chip residue, thus extending the service life of the steel structure. In addition, the modularly designed drill bit 34 can be quickly replaced according to different drilling needs, which significantly improves construction efficiency and reduces labor costs.

[0032] In summary, this utility model significantly improves the efficiency and quality of steel structure drilling operations by integrating a three-axis motion mechanism 2, a drilling mechanism 3, and a chip removal mechanism 4. This technical solution not only solves the problem of timely chip removal during drilling in existing technologies, but also improves the adaptability and construction safety of the equipment through high-precision positioning and modular design, providing reliable technical support for the field of steel structure installation.
