At this time, the two arc positioning frames are respectively on both sides of the surface of the cylindrical pipe, and the two arc positioning frames are controlled by the electric slide to approach the surface of the cylindrical pipe, and the supporting electric cylinder driving ends on the two arc positioning frames are coordinated to control the contact between the supporting block and the surface of the cylindrical pipe, and the supporting electric cylinders on the two arc positioning frames are used to drive the supporting block to position and control one side of the end face of the cylindrical pipe; Step 2: Inflate the sealing airbag so that the sealing airbag contacts the surface of the cylindrical pipe after expansion, and use the sealing airbag to control the sealing between the cylindrical pipe and the closing frame; Step 3, when performing outer bevel processing on the end face of the cylindrical pipe, firstly, one end of the cylindrical pipe is positioned inside the closed frame by using several positioning electric cylinder driving ends on the mounting frame, and then a servo electric cylinder driving end inside the connecting frame is controlled to drive a cutter to move to the outer end face of the cylindrical pipe, and the rotating frame is controlled to rotate, and the outer bevel cutting processing is performed on the end face of the cylindrical pipe by using the rotating cutter. After one of the cutters is damaged, the cutter on the other servo electric cylinder is controlled to continue to cut the outer bevel of the end face of the cylindrical pipe, and at the same time, coolant is introduced into the inside of the liquid guide ring through the liquid guide pipe, and the coolant enters the inside of the liquid guide frame through the liquid guide ring, and finally the coolant is sprayed to the end face of the cylindrical pipe through the liquid spraying ports on one side of the connecting frame, and the bevel processing of the end face of the cylindrical pipe is cooled and dusted; Step 4: After the cylindrical pipe is positioned inside the closed frame, the rotating ring is controlled to move to the inside of the end face of the cylindrical pipe by sliding the rotating ring on the fixed frame, and the driving ends of the servo electric cylinders are used to control the cutter to move to contact the inner wall of the cylindrical pipe.

When the end face of the cylindrical pipe is beveled by the cutting mechanism, the generated cutting waste enters the interior of the collecting tank through the material guide rack, and the cutting waste is scraped toward the bottom of the interior of the collecting tank by two relatively rotating collecting racks inside the collecting tank, and the coolant mixed with cutting dust is filtered by a filter plate, and finally the filtered coolant is sent out through a drain pipe, and the collected cutting waste is scraped toward the front and rear sides of the inner wall of the collecting tank by the two collecting racks, and finally the cutting waste is collected centrally by two collection frames on the front and rear sides of the frame.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: 1. In the present invention, the beveling machine is flexibly moved by a mobile base frame, so that the beveling machine is conveniently moved to one end of the cylindrical pipe, and the closed frame is covered on one end of the cylindrical pipe, and the surface of the cylindrical pipe is fixed and limited in cooperation with the positioning mechanism on the top of the frame, so as to ensure the stability of the cylindrical pipe during the beveling cutting process. Inside the closed frame, the cutting mechanism is used to bevel one end of the cylindrical pipe, and the inner and outer bevels can be selectively processed according to one end of the cylindrical pipe. The inner and outer bevels of one end of the cylindrical pipe can be processed at one time inside the closed frame, which greatly improves the processing efficiency of the cylindrical pipe bevel. In addition, when the cylindrical pipe is beveled, the noise and smoke generated in the processing process are isolated by the closed frame, which effectively reduces the pollution to the surrounding environment of the equipment during the cylindrical pipe bevel cutting process, and improves the environmental protection of the working operation of the bevel processing equipment.

[0018] 2. When performing groove cutting of cylindrical pipes, after moving the groove machine to one end of the cylindrical pipe, move one end of the cylindrical pipe to the inside of the closed frame. At this time, the two arc positioning frames are respectively on both sides of the surface of the cylindrical pipe. The two arc positioning frames are controlled by an electric slide to approach the surface of the cylindrical pipe. The support electric cylinder driving ends on the two arc positioning frames control the contact between the support block and the surface of the cylindrical pipe. The support electric cylinders on the two arc positioning frames drive the support block to position and control one side of the end face of the cylindrical pipe to ensure the stability of the cylindrical pipe during the groove cutting process.

[0019] 3. After inserting one end of the cylindrical pipe into the closed frame, inflate the sealing airbag so that the sealing airbag expands and contacts the surface of the cylindrical pipe. The sealing airbag is used to control the seal between the cylindrical pipe and the closed frame, so that the closed frame can play a role in sound insulation and dust isolation when the cylindrical pipe is cut.

[0020] 4. Coolant is introduced into the liquid guide ring through the liquid guide pipe, and then enters the liquid guide frame through the liquid guide ring. Finally, the coolant is sprayed toward the end face of the cylindrical pipe through the liquid spray port on one side of the connecting frame. The groove processing of the end face of the cylindrical pipe is cooled and dusted, thereby improving the processing quality of the groove of the end face of the cylindrical pipe and the service life of the processing tool.

[0021] 5. The generated cutting waste enters the interior of the collecting trough through the material guide rack, and two relatively rotating collecting racks are used inside the collecting trough to scrape the cutting waste to the bottom of the collecting trough, and the coolant mixed with cutting dust is filtered by a filter plate, and finally the filtered coolant is sent out through a drain pipe, and the collected cutting waste is scraped to the front and back sides of the inner wall of the collecting trough by the two collecting racks, and finally the cutting waste is collected centrally by two collecting frames on the front and back sides of the frame to reduce the waste of metal resources.

[0022] 6. By controlling the rotating frame to rotate, the rotating cutter pair is used to perform outer bevel cutting on the end face of the cylindrical pipe. After one of the cutters 1 is damaged, the cutter 1 on the other servo electric cylinder 1 is controlled to continue cutting the outer bevel of the end face of the cylindrical pipe, thereby ensuring the cutting efficiency of the outer bevel of the end face of the cylindrical pipe. Through the output shaft of the servo motor combined with the meshing transmission between the driving gear and the internal tooth groove, the cutter 2 is used to cut the inner bevel of the end face of the cylindrical pipe, so that the inner and outer bevels of the cylindrical pipe can be cut at one time inside the closed frame, thereby greatly improving the bevel cutting efficiency of the cylindrical pipe.
