[0002] Boring is a precision machining technology, mainly used for further processing of forged, cast or drilled holes. By rotating the boring tool, the hole is enlarged, the accuracy is improved, the surface roughness is reduced, and the deviation of the hole axis is corrected. Boring can significantly improve the machining accuracy and surface quality of the hole. This technology is widely used in the automotive, aerospace, machinery manufacturing and other fields, especially when processing high-precision, high-surface-quality holes. Pipeline repair is a technology that restores the normal use function of damaged and leaking transmission pipelines. It mainly includes two technologies: external anti-corrosion layer repair and internal repair. External anti-corrosion layer repair mainly involves testing and evaluating the external anti-corrosion layer, and then performing corresponding repair work based on the evaluation report.

[0023] Specifically, the end of the clamp 504 can be connected to the clamping seat 507. After the end of the clamp 504 is connected to the clamping seat 507, the sleeve 505 can be clamped on the clamping seat 507. Then, the fixing screw 506 can be tightened to fix the clamp 504 on the pipe, thereby positioning the boring body 4 at the pipe port, and the telescopic bracket 502 can drive the boring tool 2 to move back and forth when it is extended and retracted, which is convenient for boring and milling the pipe port.

[0024] like Figure 2 and Figure 4 As shown, the recovery mechanism 6 includes a recovery groove 601 fixedly installed on the front end of the positioning sleeve 501, a funnel 602 is fixedly installed on the bottom of the recovery groove 601, a sealing plug 603 is provided in the boring pipe 1, and a sealing airbag 605 is fixedly installed on the edge of the sealing plug 603. The sealing airbag 605 is connected to the exhaust port 604 and the air inlet 607, and a one-way valve 608 is provided in the air inlet 607.

[0025] Specifically, the used cutting fluid will flow into the recovery tank 601, thereby recycling the cutting fluid and preventing the cutting fluid from polluting the environment. The sealing airbag 605 can be inflated to expand the sealing airbag 605. The expanded sealing airbag 605 will block the gap between the pipeline and the sealing plug cover 603, thereby preventing the cutting fluid from flowing into the pipeline and preventing the pipeline from being contaminated.

[0026] Working principle: When in use, first place the positioning sleeve 501 on the pipe, then rotate the clamp 504 so that the end of the clamp 504 is connected to the clamping seat 507. After the end of the clamp 504 is connected to the clamping seat 507, the sleeve 505 can be clamped on the clamping seat 507.
