At the same time, the grinding head 16 performs synchronous grinding operation on the inner wall of the tube body 24 after the milling cutter 12 turns.

[0040] like Figure 2 As shown, a driving gear disc 14 for driving the telescopic rod 13 is movably installed inside the docking chuck 10, and the driving gear discs 14 of the telescopic rod 13 are driven by tooth grooves. Elastic buckles 11 are provided on both sides of the driving gear disc 14 inside the docking chuck 10. During operation, the driving gear disc 14 is rotated so that the driving gear disc 14 drives the telescopic rod 13 by the tooth grooves, and the milling cutter 12 and the grinding head 16 are driven to move by the telescopic rod 13, so that the milling cutter 12 and the grinding head 16 are close to the inner wall of the tube body 24. When the milling cutter 12 and the grinding head 16 rotate, the inner wall of the tube body 24 is processed.

[0041] like Figure 3 As shown, three groups of fixed clamps 5 are movably installed on the outer surface of the upper end of the movable base plate 6, and two groups of fixed clamps 19 are movably installed on the inner side of the fixed clamps 5. The two groups of fixed clamps 19 are symmetrically arranged, and the fixed clamps 5 and the fixed clamps 19 are driven by an electric push rod 18.

When the fixed clamping seat 5 on the movable base 6 completes the fixing operation of the tube body 24, the moving feeding of the tube body 24 to the turning part 7 can be completed through the movement adjustment of the movable base 6.

[0043] In order to improve the turning accuracy of the accelerator tube, Figure 4 As shown, the fixed base 2 and the limiting rod 3 are movably connected via a sliding seat 4, a driving seat 21 for driving the limiting rod 3 is installed on one side of the sliding seat 4, and a driving wheel 22 is movably installed on the upper end of the driving seat 21, and the driving wheel 22 is driven by a motor. Through the contact between the driving wheel 22 and the limiting rod 3, the limiting rod 3 can be driven to move when the driving wheel 22 rotates, so that the limiting rod 3 follows the movement of the tube body 24 to make corresponding movement adjustments.

[0044] like Figure 4As shown, a support sleeve 23 is spliced ​​and installed on the outer surface of one end of the limit rod 3, and a plurality of groups of first rollers 26 are arranged on the outer surface of the support sleeve 23, and the plurality of groups of first rollers 26 are distributed in a ring shape. The limit rod 3 extends the support sleeve 23 into the interior of the tube body 24, so that the first rollers 26 on the surface of the support sleeve 23 are in contact with the inner wall of the tube body 24. The inner wall of the support sleeve 23 assists in supporting the tube body 24, thereby improving the stability of the inner wall of the tube body 24 during turning and preventing the tube body 24 from shaking. Secondly, when the tube body 24 moves, the support sleeve 23 can move in the opposite direction of the tube body 24 by utilizing the setting of the first rollers 26.

[0045] like Figure 5 As shown, a fan 25 is spliced ​​and installed in the middle position of one end of the support sleeve 23, and an air intake cover 27 is fixedly installed on the outer surface of the other end of the support sleeve 23. The middle part of the air intake cover 27 is provided with a slot used to cooperate with the limit rod 3. The setting of the fan 25 makes the support sleeve 23 have a metal debris wind cleaning structure. When the turning part 7 turns the inner wall of the tube body 24, by starting the fan 25, the support sleeve 23 supports the inner wall of the tube body 24 while blowing gas into the inside of the tube body 24, so that the metal debris in the tube body 24 is discharged from one end thereof.

[0046] In order to improve the turning accuracy of the accelerator tube, Figure 6 As shown, a side-rotating clamping strip 30 is movably installed on the outer surface of the limit ring 8, and the limit ring 8 and the side-rotating clamping strip 30 are movably connected via an elastic rotating shaft. A second roller 29 is movably installed on one end of the side-rotating clamping strip 30. The side-rotating clamping strip 30 of the limit ring 8 cooperates with the second roller 29 to provide auxiliary support to the inner wall of the tube body 24 during the turning operation.

[0047] The limiting ring 8 and the tube body 24 are locked and fixed by a fastening bolt 31 , and a threaded ring 28 for cooperating with the side-rotating clamping strip 30 is movably mounted on the outer surface of the limiting ring 8 .

[0048] The machining accuracy of the inner wall of the accelerating tube is extremely high. Any tiny flaw or unevenness may affect the reflection performance of the microwave and the acceleration effect of the electron beam. However, the machining accuracy of the wall turning device mentioned above is low. The shaking of the pipeline and the tool will affect the turning effect of the inner wall of the accelerating tube, reducing the turning accuracy of the inner hole of the accelerating tube.

[0049] To this end, by providing the limiting rod 3 and the supporting sleeve 23, when the high-energy electron accelerator accelerating tube inner wall turning device is used, it is provided with an auxiliary supporting structure, which can follow the movement of the accelerating tube and provide auxiliary support from the inside thereof, thereby improving the turning accuracy of the accelerating tube inner wall, and simultaneously completing the cleaning operation of metal debris;

[0050] During operation, the tube body 24 to be turned is placed on the fixed clamping seat 5, and the three groups of fixed clamping seats 5 on the movable base plate 6 can be used to complete the fixing operation of the installed tube body 24, and the electric push rod 18 drives the fixed clamping plate 19, and the distance between the two groups of fixed clamping plates 19 can be adjusted, so that the fixed clamping plate 19 is clamped and fixed on the side of the tube body 24 to complete the fixing operation of the tube body 24. Secondly, the three groups of fixed clamping seats 5 can use the limiting slide groove 20 to make corresponding position adjustment according to the length of the tube body 24 to meet the installation operation of tube bodies 24 of different lengths. The threaded sleeve 17 is driven by a screw rod, and the screw rod is driven by a motor, so that the screw rod drives the threaded sleeve 17, and the movable base plate 6 is driven by the threaded sleeve 17, so that the movable base plate 6 moves at the upper end of the fixed base 2. When the fixed clamping seat 5 on the movable base plate 6 is completed After the fixing operation of the tube body 24, the moving base plate 6 is moved and adjusted to complete the moving feeding of the tube body 24 to the turning part 7. During the turning operation, the driving wheel 22 is driven by the motor. Through the contact between the driving wheel 22 and the limiting rod 3, the limiting rod 3 can be driven to move when the driving wheel 22 rotates, so that the limiting rod 3 follows the moving feeding of the tube body 24 and makes corresponding movement adjustment. The limiting rod 3 extends the support sleeve 23 into the interior of the tube body 24, so that the first roller 26 on the surface of the support sleeve 23 contacts the inner wall of the tube body 24. The inner wall of the support sleeve 23 assists in supporting the tube body 24, thereby improving the stability of the inner wall of the tube body 24 during turning and preventing the tube body 24 from shaking. Secondly, when the tube body 24 moves, the support sleeve 23 can move in the opposite direction of the tube body 24 by using the setting of the first roller 26.

[0051] At the same time, the fan 25 is provided so that the support sleeve 23 has a wind cleaning structure for metal debris. When the turning part 7 performs turning processing on the inner wall of the tube body 24, the fan 25 is started so that the support sleeve 23 supports the inner wall of the tube body 24 while blowing gas into the tube body 24, so that the metal debris in the tube body 24 is discharged from one end thereof.

[0052] Secondly, the inner diameters of accelerating tubes of different diameters are different, and the above device cannot be flexibly applied to accelerating tubes of different diameters, which reduces its application range. At the same time, secondary grinding is required after turning to ensure the smoothness of the inner wall of the accelerating tube, and the grinding operation of the inner wall cannot be completed simultaneously;

[0053] To this end, by providing the turning part 7, when the high-energy electron accelerator accelerating tube inner wall turning device is used, it can be applied to the turning operation of accelerating tubes of different calibers, and at the same time, the inner wall grinding operation can be completed, thereby improving its processing effect;

[0054] When in use, the two telescopic rods 13 are used to simultaneously drive the milling cutter 12 and the grinding head 16 to move. By adjusting the positions of the milling cutter 12 and the grinding head 16, they can meet the requirements of turning the inner wall of the acceleration tube with different calibers. The motor drives the rotating rod 9, so that the rotating rod 9 drives the turning part 7, so that the milling cutter 12 and the grinding head 16 on the turning part 7 rotate synchronously, and the milling cutter 12 is used to complete the turning finishing of the inner wall of the tube body 24. At the same time, the grinding head 16 performs synchronous grinding operation on the inner wall of the tube body 24 after the milling cutter 12 turns. During operation, the driving gear disc 14 is rotated, so that the driving gear disc 14 drives the telescopic rod 13 through the tooth groove, and the milling cutter 12 and the grinding head 16 are driven to move through the telescopic rod 13, so that the milling cutter 12 and the grinding head 16 are close to the inner wall of the tube body 24, and the inner wall of the tube body 24 is processed when the milling cutter 12 and the grinding head 16 rotate.

[0055] Secondly, because the accelerating tube has a certain length, when the inner hole of the accelerating tube is turned to a certain position, the accelerating tube is bent downward, so that the accelerating tube and the tool cannot maintain a horizontal state, which will affect the turning accuracy of the inner wall of the accelerating tube and reduce its use effect;

[0056] To this end, by providing the limiting ring 8, when the accelerating tube inner wall turning device for the high energy electron accelerator is used, the use of the limiting rod 3 and the supporting sleeve 23 is optimized, so that it has a multiple supporting structure, and can meet the auxiliary support of accelerating tubes of different calibers, thereby improving its application range;

[0057] During operation, the limit ring 8 is installed on the surface of the rotating rod 9. When the turning part 7 is extended into the inner wall of the tube body 24 for turning operation, the limit ring 8 follows the rotating rod 9 and synchronously extends into the interior of the tube body 24. The side-rotating clip 30 of the limit ring 8 cooperates with the second roller 29 to provide auxiliary support for the inner wall of the tube body 24 during turning operation. By rotating the threaded ring 28, the threaded ring 28 moves on the surface of the limit ring 8. The threaded ring 28 can simultaneously push several groups of side-rotating clips 30, adjust the angle of the side-rotating clips 30 on the limit ring 8, so that the second roller 29 on the side-rotating clips 30 can meet the support and fixation of the inner wall of the tube body 24 in different spaces. In combination with the setting of the support sleeve 23, the tube body 24 can be supported and fixed in two directions when it moves, thereby improving its turning stability.
