[0025] The tapping tool is inserted into the tool chuck 271, and the gap in the allowance groove 272 is compressed by tightening the fastening nut 273, so that the tapping tool is clamped by the tapping fixture 27 with an adjustable clamping force to ensure safe and reliable processing. Then the motor 28 drives the tapping fixture 27 to rotate, and at the same time, the hydraulic cylinder 25 pushes the slide plate 26 slidably installed between the rails 21 to move to the left, which is used to guide the cutting direction and depth of the tapping tool to ensure accurate and stable cutting operation, so that the tapping tool contacts the fixed mold on the fixed tooling 4, thereby performing tapping.

The fixing tool 4 is used to fix the workpiece and ensure the correct thread cutting operation. The clamping force of the fixing tool 4 can be adjusted by adjusting the three sets of screws 43 to ensure safe and reliable processing.

[0030] The following is a detailed description of the working principle of the tapping tooling for this machine tool.

[0031] like Figure 1-5As shown, the tapping tool is inserted into the tool chuck 271, and the gap of the allowance groove 272 is compressed by screwing the fastening nut 273, so that the tapping fixture 27 clamps the tapping tool with an adjustable clamping force to ensure safe and reliable processing. Then the motor 28 drives the tapping fixture 27 to rotate, and at the same time, the hydraulic cylinder 25 pushes the slide plate 26 slidably installed between the rails 21 to move to the left to guide the cutting direction and depth of the tapping tool to ensure accurate and stable cutting operation, so that the tapping tool contacts the fixed mold on the fixed tooling 4, thereby tapping. The cooling mechanism 3 is fixedly installed on the top of the slide plate 26, and the infusion tank 31 is used to guide the cutting fluid to the workpiece to help cool and lubricate the cutting area In order to improve the cutting efficiency and tool life, the input end 33 adds coolant to the reservoir 32 for cooling during processing. During cutting, the left end of the infusion tank 31 is located above the tapping fixture 27. The coolant flows out of the infusion tank 31 through the output end by opening the valve 34, and flows out through the left end of the infusion tank 31 to guide the cutting fluid to the workpiece to help cool and lubricate the cutting area. After the tapped piece is plugged into the center of the fixed seat 45, the three sets of screws 43 on the fixed seat 45 are screwed through the tool docking nut 42, so that the fixed head 44 moves to the center of the fixed seat 45 to clamp and fix the tapped piece in three directions. The fixing tool 4 is used to fix the workpiece and ensure the correct thread cutting operation. The clamping force of the fixing tool 4 can be adjusted by adjusting the three sets of screws 43 to ensure safe and reliable processing.
