A sliding seat 4 is slidably connected to the fixed rail 2. A groove corresponding to the shape of the fixed rail 2 is provided at the bottom of the sliding seat 4 to ensure the normal sliding of the sliding seat 4 on the fixed rail 2. The sliding seat 4 and the fixed rail 2 form a sliding connection structure. A fixed mounting platform 5 is fixedly installed on the top of the sliding seat 4. The sliding seat 4 and the fixed mounting platform 5 are an integrated structure, and the fixed mounting platform 5 and the sliding seat 4 slide on the fixed rail 2 to ensure the sliding effect of the sliding seat 4 and the fixed mounting platform 5 on the fixed rail 2. A fixed platform 6 is provided on the top of the fixed mounting platform 5. The fixed platform 6 is located at the center of the top of the fixed mounting platform 5, ensuring the reasonable position of the fixed platform 6 and facilitating the installation of the structure on the fixed platform 6. A rotating frame 7 is arranged above the fixed platform 6, and the rotating frame 7 and the fixed platform 6 are rotatably connected to ensure the stable rotation of the rotating frame 7 on the fixed platform 6. A first driving motor 8 is horizontally fixedly installed on the rotating frame 7. The first driving motor 8 is a stepping motor, which can control the rotation angle of the output shaft of the first driving motor 8, assist the rotation of the connecting shaft 9, and control the rotation angle of the connecting shaft 9 and the inner fixed tube 10 at the same time, assist the rotation of the connecting shaft 9 and the inner fixed tube 10, and a connecting shaft 9 is fixedly installed on the output shaft of the first driving motor 8. The connecting shaft 9 and the output shaft of the first driving motor 8 are fixedly connected. The output shaft of the motor 8 drives the connecting shaft 9 to rotate stably, thereby driving the connecting shaft 9 and the inner fixed tube 10 to rotate stably. The end of the connecting shaft 9 away from the rotating frame 7 is coaxially fixedly installed with the inner fixed tube 10. The inner fixed tube 10 is a hollow pipe to ensure the installation and adjustment of the structure inside the inner fixed tube 10. Two first positioning rings 11 are movably sleeved outside the inner fixed tube 10, and a connecting rod 12 is provided between the two first positioning rings 11 for connection. The connecting rod 12 between the first positioning rings 11 is used for fixed connection to ensure that the two first positioning rings 11 move synchronously on the inner fixed tube 10. At the same time, the moving trajectories of the first positioning ring 11 and the connecting rod 12 on the inner fixed tube 10 can be better controlled. Two second positioning rings 13 are also provided outside the inner fixed tube 10.The distance between the second positioning ring 13 and the first positioning ring 11 is the same. When the two first positioning rings 11 move synchronously, the adjusting rod 15 on the first positioning ring 11 and the adjusting rod 15 on the second positioning ring 13 rotate at the same angle. The outer walls of the first positioning ring 11 and the second positioning ring 13 are both provided with a fixed shaft seat 14. The fixed shaft seat 14 is used for the installation of the adjusting rod 15. The adjusting rod 15 swings on the fixed shaft seat 14. The adjusting rod 15 and the fixed shaft seat 14 form a rotating connection structure. The adjusting rod 15 is rotatably connected to the fixed shaft seat 14. The end of the adjusting rod 15 away from the fixed shaft seat 14 is fixedly connected with a connector 16. The adjusting rod 15 and the connector 16 are an integrally formed structure, and the connectors 16 on the two adjusting rods 15 are staggered. The connectors 16 on the two adjusting rods 15 are staggered. In this way, when the two adjusting rods 15 and the connectors 16 are close to each other, the connectors 16 on the adjusting rods 15 will not affect each other, ensuring that the adjusting rods 15 are close to each other.

[0035] An annular buckle 17 is fixedly installed at one end of the connector 16 away from the adjusting rod 15, and a rotating shaft sleeve 18 is arranged between the annular buckles 17 for rotational connection. The annular buckle 17 and the rotating shaft sleeve 18 form a rotating connection structure. The shaft on the annular buckle 17 rotates in the rotating shaft sleeve 18. The annular buckle 17 and the rotating shaft sleeve 18 form a rotating connection structure. An intermediate plate 19 is fixedly installed on the rotating shaft sleeve 18, and the intermediate plate 19 is located between the adjusting rods 15. The intermediate plate 19 is located on the inner side of the outer wall of the rotating shaft sleeve 18, and the intermediate plate 19 is located at the center position between the two adjusting rods 15. The intermediate plate 19 is away from the rotating shaft sleeve 18. An arc spring 20 is fixedly installed at one end. Due to the existence of the arc spring 20, the two adjusting rods 15 generate elastic force when they are close to each other, which is used for resetting the two adjusting rods 15 after they are close to each other. At the same time, the structure composed of the middle plate 19 and the arc spring 20 ensures that the middle plate 19 and the support head 21 are located on the same vertical plane, ensuring the contact between the support head 21 and the inner wall of the cylinder sleeve. The arc spring 20 is located between the two adjusting rods 15. A support head 21 is provided on the side of the rotating shaft sleeve 18 opposite to the middle plate 19. The support head 21 is supported at the corresponding position of the inner wall of the cylinder sleeve to ensure the sleeve fixing effect of the cylinder sleeve.

[0036] The fixed shaft seat 14 is distributed in a circular array with the central axis of the first adjusting ring 11 and the second adjusting ring 13 as the array center. A structure consisting of multiple groups of fixed shaft seats 14, adjusting rods 15, connecting heads 16, annular buckles 17, rotating shaft sleeves 18, intermediate plates 19, arc springs 20, and support heads 21 supports the cylinder liner from the inside to ensure the installation and fixing effect of the cylinder liner.

[0037] A limit plate 22 is fixedly installed in the fixed shaft seat 14, and the limit plate 22 is arranged on the side opposite to the rotation direction of the adjustment rod 15. The limit plate 22 limits the movement of the adjustment rod 15 to prevent the adjustment rod 15 from moving too much, thereby achieving a positioning and limiting effect.

[0038] A first electric push rod 23 is horizontally arranged on the rotating frame 7, and a pressure ring 24 is movably sleeved outside the inner fixed tube 10. A gap is left between the pressure ring 24 and the inner fixed tube 10 to ensure that the pressure ring 24 will not contact the inner fixed tube 10 when moving, so as to prevent the pressure ring 24 and the inner fixed tube 10 from rubbing against each other, thereby affecting the normal movement of the pressure ring 24. The contact position between the pressure ring 24 and the first positioning ring 11 is a sliding connection to ensure the rotation between the pressure ring 24 and the first positioning ring 11. A connecting ring 25 is fixedly installed at one end of the piston rod of the first electric push rod 23 away from the first electric push rod 23. The connecting ring 25 is fixedly installed on the outer side wall of the pressure ring 24. The output shaft of the first electric push rod 23 applies thrust to the connecting ring 25, thereby driving the movement of the pressure ring 24. The movement of the pressure ring 24 applies pressure to the first positioning ring 11, and the two first positioning rings 11 and the connecting rod 12 move outside the inner fixed tube 10. The piston rod of the first electric push rod 23 pushes the connecting ring 25 to move, and the movement of the connecting ring 25 synchronously drives the pressure ring 24 to move on the inner fixed tube 10. When the pressure ring 24 moves on the inner fixed tube 10, the pressure ring 24 applies pressure to the first adjustment ring 11, thereby driving the first adjustment ring 11 to move on the inner fixed tube 10. The movement of the first adjustment ring 11 on the inner fixed tube 10 drives another first adjustment ring 11 to move. The first adjustment ring 11 and the connecting rod 12 form a structure on the inner fixed tube 10. When the first adjusting ring 11 moves, the distance between the first adjusting ring 11 and the second adjusting ring 13 becomes smaller. When the first adjusting ring 11 moves, the adjusting rod 15 rotates in the fixed shaft seat 14. When the bottom of the adjusting rod 15 rotates in the fixed shaft seat 14, the annular buckle 17 on the top of the adjusting rod 15 rotates in the rotating shaft sleeve 18. At the same time, when the adjusting rod 15 rotates in the fixed shaft seat 14, it also applies pressure to the arc spring 20. The arc spring 20 is deformed under pressure, which is used to adjust the rod 15. Reset, so that the V-shaped structure angle formed by the fixed shaft seat 14, adjusting rod 15, connecting head 16, annular buckle 17, rotating shaft sleeve 18, intermediate plate 19, arc spring 20, and supporting head 21 changes, achieving different supporting effects, the intermediate plate 19 and the supporting head 21 form a structure to maintain a vertical state, the supporting head 21 is vertically supported at the corresponding position of the inner wall of the cylinder sleeve, and the connecting shaft 9 is driven to rotate by the output shaft of the first drive motor 8, and the rotation of the connecting shaft 9 drives the internal fixed tube 10 to rotate, thereby driving the cylinder sleeve to rotate. After the cylinder sleeve is processed, the piston rod of the first electric push rod 23 moves in the opposite direction, and the fixed shaft seat 14, adjusting rod 15, connecting head 16, annular buckle 17, rotating shaft sleeve 18, intermediate plate 19, arc spring 20, and supporting head 21 The structure is no longer supported by the cylinder sleeve, and the cylinder sleeve is removed from the fixed shaft seat 14, adjusting rod 15, connecting head 16, annular buckle 17, rotating shaft sleeve 18, intermediate plate 19, arc spring 20, and supporting head 21.

[0039] The inner fixing tube 10 is provided with an inner fixing tube 1001, and a transverse sliding plate 26 is slidably connected in the inner fixing tube 1001, and the transverse sliding plate 26 is fixedly installed in the radial direction of the second positioning ring 13, and the transverse sliding plate 26 slides in the inner fixing tube 1001, and the transverse sliding plate 26 and the inner fixing tube 1001 form a sliding connection structure. When the second positioning ring 13 moves, the transverse sliding plate 26 is driven to move synchronously, so as to adjust the distance between the second positioning ring 13 and the first positioning ring 11, thereby changing the fixed shaft seat 14, the adjusting rod 15, The adjustment range of the structure composed of the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the intermediate plate 19, the arc spring 20, and the supporting head 21, the transverse sliding plate 26 is connected to the screw 27 through the internal thread, and the transverse fixing plate 28 is radially fixedly installed in the inner fixed tube 10, and the rotating sleeve 29 is rotatably connected to the center position of the transverse fixing plate 28, and the rotating sleeve 29 is fixedly installed on the outside of the screw 27. The rotation of the screw 27 drives the transverse sliding plate 26 to move in the inner fixed tube 1001, and the movement of the transverse sliding plate 26 drives the second adjustment ring 13 to move.

[0040] A hexagonal rotating head 30 is fixedly installed at one end of the screw rod 27 away from the rotating frame 7. The hexagonal rotating head 30 is a hexagonal structure. The hexagonal rotating head 30 is rotated by a wrench. The rotation of the hexagonal rotating head 30 drives the rotating sleeve 29 to rotate in the horizontal fixed plate 28, thereby assisting the two second adjustment rings 13 and the horizontal sliding plate 26 to move synchronously.

[0041] A second drive motor 31 is fixedly installed on the fixed platform 6, and the output shaft of the second drive motor 31 is fixedly connected to the center position of the bottom of the rotating frame 7. The output shaft of the second drive motor 31 drives the rotating frame 7 to rotate, thereby changing the angle of the cylinder sleeve on the structure composed of the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the middle plate 19, the arc spring 20, and the supporting head 21.

[0042] An assembly frame 32 is fixedly installed on one side of the rotating frame 7, and a second electric push rod 33 is vertically fixedly installed on the assembly frame 32. A connecting seat 34 is fixedly installed on the end of the piston rod of the second electric push rod 33, and a gear ring 35 is fixedly installed on the bottom of the connecting seat 34. A docking seat 36 is fixedly installed on the top of the second drive motor 31. The gear ring 35 is movably engaged in the docking seat 36, and the piston rod of the second electric push rod 33 drives the gear ring 35 to rise and fall. After the gear ring 35 is raised and lowered, the rotation angle of the gear ring 35 is controlled by the output shaft of the second drive motor 31. The second drive motor 31 is a stepping motor, and the rotation angle control effect is better, ensuring that the gear ring 35 can still be engaged in the docking seat 36 after the rotation stops at a certain angle.

[0043] The shape of the gear ring 35 matches the shape of the groove formed on the docking seat 36 .

[0044] Working principle: The first step: according to the inner diameter of the cylinder sleeve, adjust the distance between the first adjusting ring 11 and the second adjusting ring 13, and connect the wrench and the hexagonal rotating head 30. The wrench rotates the hexagonal rotating head 30 to rotate the rotating sleeve 29, and the rotating sleeve 29 drives the screw rod 27 to rotate. When the screw rod 27 rotates, it drives the transverse sliding plate 26 threadedly connected thereto to move on the screw rod 27. The movement of the transverse sliding plate 26 drives the second adjusting ring 13 to move synchronously. The two second adjusting rings 13 move on the inner fixed tube 10, thereby changing the relative distance between the first adjusting ring 11 and the second adjusting ring 13, thereby changing the adjustability of the structure composed of the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the intermediate plate 19, the arc spring 20, and the supporting head 21 to adapt to cylinder sleeves with smaller or larger inner diameters.

[0045] Step 2: The piston rod of the first electric push rod 23 pushes the connecting ring 25 to move, and the connecting ring 25 moves synchronously to drive the pressing ring 24 to move on the inner fixed tube 10. When the pressing ring 24 moves on the inner fixed tube 10, the pressing ring 24 applies pressure to the first adjusting ring 11, thereby driving the first adjusting ring 11 to move on the inner fixed tube 10. The movement of the first adjusting ring 11 on the inner fixed tube 10 drives another first adjusting ring 11 to move. The first adjusting ring 11 and the connecting rod 12 form a structure in the inner fixed tube. When the first adjusting ring 11 moves, the distance between the first adjusting ring 11 and the second adjusting ring 13 becomes smaller. When the first adjusting ring 11 moves, the adjusting rod 15 will rotate in the fixed shaft seat 14. When the bottom of the adjusting rod 15 rotates in the fixed shaft seat 14, the annular buckle 17 on the top of the adjusting rod 15 rotates in the rotating shaft sleeve 18. At the same time, when the adjusting rod 15 rotates in the fixed shaft seat 14, it will also pressurize the arc spring 20. The arc spring 20 is deformed under pressure and is used to reset the adjusting rod 15. In this way, the V-shaped structure angle formed by the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the intermediate plate 19, the arc spring 20, and the supporting head 21 changes, achieving different supporting effects. The structure composed of the intermediate plate 19 and the supporting head 21 remains in a vertical state, and the supporting head 21 is vertically supported at the corresponding position of the inner wall of the cylinder sleeve. The connecting shaft 9 is driven to rotate by the output shaft of the first driving motor 8, and the rotation of the connecting shaft 9 drives the inner fixed tube 10 to rotate. The cylinder sleeve is moved, thereby driving the cylinder sleeve to rotate. After the cylinder sleeve is processed, the piston rod of the first electric push rod 23 moves in the opposite direction, and the structure composed of the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the middle plate 19, the arc spring 20, and the supporting head 21 no longer supports the cylinder sleeve. The cylinder sleeve is removed from the structure composed of the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the middle plate 19, the arc spring 20, and the supporting head 21.

[0046] The third step: the output shaft of the second drive motor 31 drives the rotating frame 7 to rotate, so as to realize the rotation of the cylinder sleeve on the structure composed of the fixed shaft seat 14, the adjusting rod 15, the connecting head 16, the annular buckle 17, the rotating shaft sleeve 18, the intermediate plate 19, the arc spring 20, and the supporting head 21, and assist the milling cutter in processing the cylinder sleeve. At the same time, when the rotating frame 7 rotates, the connecting seat 34 and the gear ring 35 are driven to move upward by the second electric push rod 33 piston rod, and the gear ring 35 is not stuck in the docking seat 36. The rotating frame 7 and the structure on the rotating frame 7 can rotate. After the rotating frame 7 stops rotating, the second electric push rod 33 piston rod drives the gear ring 35 to descend, so as to realize the engagement of the gear ring 35 in the docking seat 36, and realize the fixation of the rotating frame 7 after it stops.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
