Description

[0049] See Figure 1 , Figure 1 This is a schematic diagram of a drilling mechanism for an insulation cotton furnace cavity according to an embodiment of this application. At least one embodiment of this application proposes a drilling mechanism for an insulation cotton furnace cavity, comprising a frame 1, a cutting tool assembly 2, a drive and lifting assembly 3, and an adjustment assembly 4. The frame 1 is mounted on the insulation cotton furnace cavity. The cutting tool assembly 2 includes a cutting tool holder 21 and a cutting tool 22 mounted on the cutting tool holder 21. The drive and lifting assembly 3 is mounted on the frame 1 and is drivenly connected to the cutting tool holder 21. The drive and lifting assembly 3 drives the cutting tool holder 21 to rotate and simultaneously move the cutting tool 22 up and down along a preset axis. The adjustment assembly 4 is connected between the cutting tool holder 21 and the cutting tool 22, and adjusts the distance between the cutting tool 22 and the preset axis.

[0050] In this embodiment, the preset axis is vertical, and the drilling mechanism for the insulation cotton furnace cavity is mounted on top of the insulation cotton furnace cavity during use. The frame 1 plays a crucial supporting and positioning role, serving as a stable mounting base for the entire drilling mechanism and ensuring that other components can accurately operate on the insulation cotton furnace cavity during drilling. The cutting tool assembly 2 is the part that directly acts on the insulation cotton for drilling, including a tool holder 21 and a cutting tool 22 mounted on the tool holder 21. The tool holder 21 serves to fix and support the cutting tool 22, ensuring its stability and accuracy during operation, allowing the cutting tool 22 to cut the insulation cotton according to a predetermined method.

[0051] The drive lifting assembly 3 is mounted on the frame 1 and is driven and connected to the tool holder 21. It not only drives the tool holder 21 to rotate the tool 22 along a preset axis, but also allows the tool holder 21 to move the tool 22 up and down along the preset axis. This coordinated rotation and lifting motion enables the tool 22 to complete the drilling operation on the insulation cotton. The adjustment assembly 4 is connected between the tool holder 21 and the tool 22, and its function is to adjust the distance between the tool 22 and the preset axis. In actual drilling operations, different insulation cotton furnace cavities may require holes of different sizes. The adjustment assembly 4 can flexibly adjust the distance between the tool 22 and the preset axis according to specific needs to meet the requirements of different hole diameters.

[0052] According to the embodiment of this application, the drilling mechanism for the insulation cotton furnace cavity first requires preparation based on the required hole size. The preset axis of the drilling mechanism is precisely aligned with the axis of the hole to be drilled. Then, the distance between the cutter 22 and the preset axis is adjusted using the adjusting component 4 until it matches the radius of the required hole. After adjustment, the drive component is activated, at which point the cutter 22 rotates and rises simultaneously. This mechanized drilling operation effectively replaces the traditional manual hole cutting method. Compared to manual hole cutting, mechanized drilling significantly shortens drilling time, greatly improves work efficiency, and also significantly improves drilling quality, such as producing more regular holes with higher dimensional accuracy.

[0053] In some embodiments, the drive lifting assembly 3 includes a lifting frame 31, a lifting machine 32, a drive unit 33, and a lifting nut 34. The lifting frame 31 is slidably connected to the frame 1 along a preset axis. The lifting machine 32 is mounted on the lifting frame 31 and is provided with a lifting screw 321 rotatably connected to the lifting machine 32. The lifting screw 321 can rotate along the preset axis and is fixedly connected to the tool holder 21. In some embodiments, the drive unit 33 includes a drive motor 331 and a reducer 332. Specifically, both the drive motor 331 and the reducer 332 are mounted on the lifting frame 31. The output shaft of the drive motor 331 is connected to the reducer 332 via a coupling 333, and the output shaft of the reducer 332 is connected to the lifting machine 32. The reducer 332 outputs a rotational speed to drive the lifting screw 321 to rotate. The lifting nut 34 is fixedly connected to the frame 1, and the lifting screw 321 is threadedly connected to the lifting nut 34.

[0054] In some embodiments, the drive power supply and the hoist 32 are mounted on one side of the top of the lifting frame 31, and the other side of the lifting frame 31 is equipped with a counterweight 7 for balance. The weight of the counterweight 7 is precisely calculated and configured according to the weight of components such as the drive lifting assembly 3 and the cutting tool assembly 2, so that the entire insulation cotton furnace cavity drilling mechanism remains balanced during operation, reducing equipment vibration and improving drilling accuracy.

[0055] Specifically, the lifting frame 31 is connected to the frame 1 via a sliding connection along a preset axis, allowing the lifting frame 31 to slide stably along the preset axis. The lifting machine 32 is mounted on the lifting frame 31 and is equipped with a lifting screw 321. The lifting screw 321 is rotatably connected to the lifting machine 32 and can rotate along the preset axis. Simultaneously, the lifting screw 321 is also fixedly connected to the tool holder 21. The drive unit 33 is also mounted on the lifting frame 31 and is driven by the lifting screw 321, providing power for its rotation. The lifting nut 34 is fixedly connected to the frame 1. The lifting screw 321 and the lifting nut 34 are connected by a thread. When the lifting screw 321 rotates under the drive of the drive unit 33, due to the fixing effect of the lifting nut 34, the lifting screw 321 moves up and down along the thread, thereby causing the tool holder 21 and the tool 22 to move up and down together.

[0056] In some embodiments, to further ensure the stability and accuracy of the lifting frame 31 during the sliding process, a guide optical shaft 5 is fixed on the frame 1, and a linear bearing 51 is slidably connected to the guide optical shaft 5, with the linear bearing 51 fixedly connected to the lifting frame 31. When the lifting frame 31 slides along a preset axis, the guide optical shaft 5 and the linear bearing 51 can provide good guidance, preventing the lifting frame 31 from deviating during movement and ensuring the movement accuracy of the tool holder 21 and the tool 22.

[0057] SeeFigure 2 In some embodiments, the tool holder 21 is fixedly connected to a fixing sleeve 211, which is fixedly connected to the lifting screw 321. The tool holder 21 is fixedly connected to the lifting screw 321 through the fixing sleeve 211. The fixing sleeve 211 enhances the stability of the connection between the tool holder 21 and the lifting screw 321, so that when the lifting screw 321 drives the tool holder 21 to move, the tool holder 21 can reliably follow the movement without loosening or displacement, thus ensuring the stability of the drilling operation.

[0058] In some embodiments, to further strengthen the connection between the lifting screw 321 and the fixed sleeve 211, a fixed shaft 3211 is fixedly connected to the end of the lifting screw 321. The fixed shaft 3211 is placed inside the fixed sleeve 211, and a fixing pin 3212 connected to the fixed sleeve 211 is provided on the fixed sleeve 211. Specifically, a fixed shaft 3211 is fixedly connected to the end of the lifting screw 321, and the fixed shaft 3211 is placed inside the fixed sleeve 211. Simultaneously, a fixing pin 3212 connected to the fixed sleeve 211 is provided on the fixed sleeve 211. The fixing pin 3212 can prevent the fixed shaft 3211 from rotating or moving axially within the fixed sleeve 211, further improving the reliability and stability of the entire connection structure.

[0059] See Figure 1 In some embodiments, the frame 1 includes a main frame 11, a secondary frame 12, and a cantilever beam 13. The secondary frame 12 is fixedly connected to the main frame 11. The cantilever beam 13 is fixedly connected to the secondary frame 12, and a lifting nut 34 is fixed to the cantilever beam 13. Specifically, the secondary frame 12 and the main frame 11 are combined together by a fixed connection, providing a more stable foundation structure for the frame 1. The cantilever beam 13 is also fixedly connected to the secondary frame 12, and the lifting nut 34 is fixedly installed on the cantilever beam 13. This frame 1 structure is reasonably designed, ensuring the overall strength of the frame 1 while providing suitable installation positions for other components.

[0060] See Figure 2 , Figure 2 This is a partial cross-sectional view of a drilling mechanism for a thermal insulation cotton furnace cavity according to an embodiment of this application. In some embodiments, the cutter 22 is provided with an adjusting part 221 and a cutting edge 222. The adjusting part 221 is movably connected to the cutter holder 21, and the cutting edge 222 is fixedly connected to the adjusting part 221. The cutting edge 222 is used to cut the thermal insulation cotton. The adjusting part 221 is mainly used for movably connecting to the cutter holder 21. Through the adjusting part 221, the position of the cutter 22 can be adjusted on the cutter holder 21 as needed to change the distance from the preset axis. The cutting edge 222 is fixedly connected to the adjusting part 221 and is the part directly used to cut the thermal insulation cotton. During the rotation and lifting of the cutter 22, the cutting edge 222 cuts the thermal insulation cotton to complete the drilling operation.

[0061] In some embodiments, the cutting edge 222 of the tool 22 is made of a high-strength, high-wear-resistant material, and the cutting edge shape is arc-shaped or serrated, which can improve the smoothness and perpendicularity of the drilling edge while ensuring drilling efficiency.

[0062] See Figure 2 and Figure 3 , Figure 3 This is a partial structural diagram of a drilling mechanism for an insulation cotton furnace cavity according to an embodiment of this application. In some embodiments, the adjusting component 4 includes adjusting holes 41 and adjusting bolts 42. Several adjusting holes 41 are provided and radially arranged on the tool holder 21 with a preset axis as the center. The adjusting part 221 can move within the adjusting holes 41 to adjust the distance between the tool 22 and the preset axis. The adjusting bolts 42 are threadedly connected to the adjusting part 221 to fix the adjusting part 221 to the tool holder 21. Several adjusting holes 41 are radially arranged on the tool holder 21 with a preset axis as the center. The adjusting part 221 of the tool 22 can move within these adjusting holes 41. By positioning it in different adjusting holes 41, the distance between the tool 22 and the preset axis can be adjusted. The adjusting bolts 42 are threadedly connected to the adjusting part 221. When the adjusting part 221 moves to a suitable position, tightening the adjusting bolts 42 can fix the adjusting part 221 to the tool holder 21, ensuring that the position of the tool 22 does not change during drilling.

[0063] In some embodiments of this application, the tool holder 21 is provided with four cutting tools 22 connected by four adjusting components 4. It is understood that the specific position and number of cutting tools 22 can be changed and designed according to specific usage needs.

[0064] In some embodiments, the adjusting hole 41 is configured as an oblong hole. The adjusting part 221 is provided with an adjusting outer wall 2211 that fits against the inner wall of the oblong hole. To allow the adjusting part 221 to move more smoothly within the adjusting hole 41 and to adjust its position more precisely, the adjusting hole 41 is configured as an oblong hole. Simultaneously, the adjusting part 221 is provided with an adjusting outer wall 2211 that fits against the inner wall of the oblong hole. This design ensures that the adjusting part 221 maintains a certain range of motion when moving within the oblong hole, while also providing good stability when stationary, thus improving the accuracy and reliability of the adjustment.

[0065] See Figure 1In some embodiments, the drilling mechanism for the insulation cotton furnace cavity further includes an adjusting support assembly 6. The adjusting support assembly 6 includes an adjusting outer tube 61, an adjusting inner tube (not shown in the figure), and fixing bolts 62. The adjusting outer tube 61 is fixedly connected to the frame 1, and has a plurality of first adjusting holes 611 along a preset axis. The adjusting inner tube is disposed inside the adjusting outer tube 61, and its bottom end can extend beyond the bottom end of the adjusting outer tube 61. The adjusting inner tube has a plurality of second adjusting holes along a preset axis. The fixing bolts 62 are used to connect a first adjusting hole 611 and a second adjusting hole.

[0066] With the above configuration, the drilling mechanism for the insulation cotton furnace cavity is equipped with an adjustable support component 6. The function of the fixing bolt 62 is to connect a first adjusting hole 611 and a second adjusting hole. By selecting different first adjusting holes 611 and second adjusting holes for connection, the length of the inner adjusting tube extending out of the outer adjusting tube 61 can be adjusted, thereby achieving fine adjustment of the overall height or angle of the drilling mechanism to adapt to different working scenarios and needs.

[0067] In this embodiment, the furnace cavity drilling mechanism for insulating cotton is used by selecting a suitable cutting tool 22 according to the specifications of the furnace cavity and the required drilling diameter, and installing it in the corresponding diameter adjustment hole 41 on the tool holder 21. Simultaneously, counterweights 7 are installed according to the weight of each component of the drilling mechanism to ensure equipment balance. The drilling mechanism is moved to the top of the furnace cavity, and the height of the frame 1 is adjusted using the adjustable feet to keep the frame 1 horizontal and stably placed on the top of the furnace cavity. The drive motor 331 drives the reducer 332, which outputs a suitable speed to drive the lifting machine 32. The lifting screw 321 rotates slowly, and the lifting frame 31 descends smoothly along the guide shaft 5. The cotton cutting tool 22 descends accordingly and begins to cut the insulating cotton. During the cutting process, the descent speed is controlled according to a preset slow descent speed. After the required depth is reached, the drive motor 331 reverses, and the lifting screw 321 drives the lifting frame 31 to rise rapidly, completing one drilling operation. After drilling is completed, the drilled holes undergo quality inspection, including measuring whether the hole diameter meets the requirements, checking whether the hole wall is smooth and perpendicular, and inspecting for burrs and lint shedding. The inspection results show that the drilled holes in this embodiment have small diameter errors, smooth walls, and small perpendicularity deviations, effectively meeting actual production needs.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
