[0002] As a key connecting component of refrigeration equipment, the processing quality of air conditioning flanges directly affects sealing performance, durability, and energy efficiency. Traditional cutting tools (such as high-speed steel and ordinary cemented carbide) often face problems such as rapid tool wear, chipping, and insufficient surface roughness when machining cast iron, stainless steel, or powder metallurgy flanges. Powder metallurgy cutting tools (such as cemented carbide, cermet, CBN, etc.) have significantly improved the accuracy, efficiency, and tool life of boring operations through innovations in materials science, coating technology, and structural design. Some existing metallurgical cutting tools are integrally formed, requiring replacement of the entire tool when the tool head is damaged. The limitations of traditional integral cutting tools in terms of tool replacement efficiency, inventory management, and cost control are becoming increasingly apparent. Modular and detachable structures allow for quick replacement of worn parts, and the tools are inconvenient to install. In view of these issues, this case study was conducted to address the above problems. Utility Model Content

[0020] Example 1: Please refer to Figures 1-4 The powder metallurgical tool for boring holes in air conditioning flanges includes a fixed base 7, a connecting plate 18, and a lifting rod 22. The fixed base 7 has an internal mounting groove 5 on one side, and a mounting block 3 is installed inside the mounting groove 5. A tool body 10 is connected to one side of the mounting block 3, and a threaded groove 13 is provided at one end of the tool body 10. A threaded rod 12 is threadedly installed inside the threaded groove 13, and a tool head 11 is connected to one side of the threaded rod 12.

A connecting plate 18 is installed on both sides of one end of the tool body 10, and a locking block 19 is connected to the inner wall of one side of the connecting plate 18. A locking groove 20 that cooperates with the locking block 19 is provided on the outer wall of the tool head 11. A lead screw 9 is installed on the inner wall above the fixed base 7, and a lifting rod 22 is threadedly installed on the outer wall below the lead screw 9. A locking block 6 is connected to the bottom end of the lifting rod 22, and a locking groove 4 that cooperates with the locking block 6 is provided on the outer wall of the mounting block 3.

[0021] A damper 21 is installed on the inner wall of the other side of the connecting plate 18, and a return spring 17 is installed on the outer wall of one end of the damper 21.

[0022] The inner wall of one side of the locking sleeve 16 is provided with internal threads, and the outer wall of one end of the tool body 10 is provided with external threads, forming a threaded connection structure between the locking sleeve 16 and the tool body 10.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when using this structure, by rotating the locking sleeve 16, the threaded engagement causes the locking sleeve 16 to move to the left. Then, the connecting plate 18 disengages from the locking sleeve 16. After the locking sleeve 16 is no longer pressing, the damper 21 and the return spring 17 reset, causing the connecting plate 18 to move the locking block 19 away from the locking groove 20. Then, the cutter head 11 is rotated, and the threaded rod 12 engages with the threaded groove 13. The threaded rod 12 moves out of the threaded groove 13, making it easy to disassemble and replace the cutter head 11.

[0024] Example 2: A positioning groove 1 is provided on the inner wall below the mounting groove 5, and a positioning block 2 that mates with the positioning groove 1 is connected to the bottom end of the mounting block 3;

[0025] Magnetic blocks 14 are installed on the bottom of the positioning block 2 and the inner wall of the positioning groove 1, and the magnetic poles of opposite sides of the magnetic blocks 14 are different.

[0026] A knob 8 is connected to the top of the lead screw 9, and a nut 15 is threaded on the outer wall above the lead screw 9;

[0027] Limiting blocks are connected to both sides of the top of the lifting rod 22, and the inner wall of the fixed base 7 is provided with limiting grooves that cooperate with the limiting blocks.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when using this structure, the mounting block 3 is inserted into the mounting groove 5, and then the positioning block 2 is positioned into the positioning groove 1. The magnetic blocks 14 are magnetically attracted and positioned. The nut 15 is rotated to move upward, and then the knob 8 is rotated to make the lead screw 9 rotate simultaneously. The threaded engagement causes the lifting rod 22 to drive the locking block 6 into the locking groove 4 for fixation, which facilitates the installation of the tool body 10.

[0029] Working principle: When using this device, first fix the tool body 10 to the fixed base 7 for use;

[0032] Step 2: Move the nut 15 upward by rotating it, and then rotate the knob 8 to rotate the lead screw 9 at the same time. The threaded engagement causes the lifting rod 22 to drive the locking block 6 into the locking groove 4 for fixation. Then rotate the nut 15 downward again to fit tightly against the fixing seat 7 for further locking.

[0033] Implementation steps for the second innovation point:

[0034] Step 1: By rotating the locking sleeve 16, the threaded engagement causes the locking sleeve 16 to move to the left. Then the connecting plate 18 disengages from the locking sleeve 16. After the locking sleeve 16 is no longer pressing, the damper 21 and the return spring 17 reset, causing the connecting plate 18 to move the locking block 19 away from the locking groove 20.

[0035] Step 2: Then rotate the cutter head 11, the threaded rod 12 engages with the threaded groove 13, the threaded rod 12 moves out of the threaded groove 13, and the cutter head 11 is disassembled.
