[0038] When it is necessary to perform inner clamping on the cylinder liner to machine the outer surface of the cylinder liner, start the servo motor 1 22, drive the rotating shaft 23 to rotate through the servo motor 1 22, and drive the bent clamping arm 21 to rotate through the rotating shaft 23 (as shown in Figure 2 and Figure 4 ). At this time, it can adapt to perform inner clamping work on cylinder liners with smaller inner diameters, improving adaptability.

The adjustable clamping arm 4 can be further limited through the second limiting chute 29 on the auxiliary limiting mechanism 6, improving the stability of the adjustable clamping arm 4;

[0039] Embodiment 4, on the basis of Embodiment 1, by Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9Given that, the telescopic adjustment mechanism 3 is composed of a multi-stage hydraulic telescopic rod 30 and a connecting plate 31. One end of the multi-stage hydraulic telescopic rod 30 is fixedly inserted through the side of one end of the mounting seat 2, and the connecting plate 31 is fixedly connected to the other end of the multi-stage hydraulic telescopic rod 30. One end of the inner clamping auxiliary support mechanism 5 is fixedly connected to the connecting plate 31. The inner clamping auxiliary support mechanism 5 is composed of a limit sleeve 32, a central support column 33, a servo motor II 34, a worm 35, a worm gear 36, a multi-groove rope pulley 37, a number of traction steel ropes 38, a number of inclined guide rails 39, a number of tension springs 40, a number of limit top seats 41, a number of limit inner support arms 42 and a number of spring shafts 43. The limit sleeve 32 is fixedly connected to the inside of the adjusting chuck 1. The central support column 33 is slidably connected to the inside of the limit sleeve 32 and fixedly connected to the connecting plate 31.

The servo motor II 34 is fixedly connected to one end inside the central support column 33. The worm 35 is fixedly connected to the output shaft of the servo motor II 34. The worm gear 36 and the multi-groove rope pulley 37 are rotatably connected to the inside of the central support column 33 through a synchronous shaft 47. The worm gear 36 meshes with the worm 35. The inclined guide rail 39 is fixedly connected to the side inside the mounting groove 46. The limit top seat 41 is slidably connected to the inclined guide rail 39. The traction steel rope 38 is connected between the limit top seat 41 and the multi-groove rope pulley 37 and passes through the inner groove 44 and the through groove 45. The tension spring 40 is connected between the limit top seat 41 and the central support column 33. The limit inner support arm 42 is rotatably connected to the inside of the mounting groove 46 through a spring shaft 43;

[0040] When the adjustable clamping arm 4 performs inner clamping on the cylinder liner, the connecting plate 31 is driven to move through the multi-stage hydraulic telescopic rod 30, and the central support column 33 is driven to move through the connecting plate 31, so that one end of the central support column 33 moves between the adjustable clamping arms 4. Start the servo motor II 34, drive the worm 35 to rotate through the servo motor II 34, drive the worm gear 36 to rotate through the worm 35, drive the multi-groove rope pulley 37 to rotate through the worm gear 36. The multi-groove rope pulley 37 tightens the traction steel rope 38, and the traction steel rope 38 pulls the limit top seat 41, so that the limit top seat 41 slides on the inclined guide rail 39. During the sliding process of the limit top seat 41, it will push the limit inner support arm 42, so that the limit inner support arm 42 moves out of the inside of the mounting groove 46, and the bending type clamping arm 21 is limited and supported through the limit inner support arm 42 (as Figure 2 and Figure 4 shown), thereby improving the stability of the bending type clamping arm 21. When the processing is completed and the inner clamping auxiliary support mechanism 5 needs to be reset, control the servo motor II 34 to reverse, so that the traction steel rope 38 is in a relaxed state, drive the limit top seat 41 to reset through the tension spring 40, the limit top seat 41 releases the limit on the limit inner support arm 42, and drive the limit inner support arm 42 to reset through the spring shaft 43, so as to release the limiting effect of the limit inner support arm 42 on the bending type clamping arm 21;

[0041] Embodiment 5, based on Embodiment 1, is given by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 10 .

The hydraulic telescopic rod 49 is rotatably connected to the second support 48 and the support arm 51, and the limiting external support arm 50 is rotatably connected to the first support 28 through a movable shaft 52.

[0042] When the adjustable clamping arm 4 externally clamps the cylinder liner, the hydraulic telescopic rod 49 is started. By the elongation of the hydraulic telescopic rod 49, the support arm 51 is pushed, and the support arm 51 pushes the limiting external support arm 50, so that the limiting external support arm 50 rotates around the first support 28, and the bending clamping arm 21 is limited and pressed through the limiting external support arm 50 (as shown in Figure 1 and Figure 3 ), thereby improving the stability of the bending clamping arm 21. When the processing is completed and the external clamping auxiliary support mechanism 7 needs to be reset, the hydraulic telescopic rod 49 is controlled to contract.

[0043] During work, by setting an adjusting chuck composed of a support disk body, a small bevel gear, an internal hexagon adjusting shaft, a large bevel gear, a rotating disk, and a planar thread, the position of the adjustable clamping arm can be adjusted, so as to be adaptable to clamping and limiting cylinder liners with different diameters. By setting an auxiliary limiting mechanism composed of an auxiliary limiting disk and a number of supports I, further limiting of the adjustable clamping arm can be achieved, improving the stability of the adjustable clamping arm, and at the same time, auxiliary support for the external clamping auxiliary support mechanism can be realized. By setting an adjustable clamping arm composed of a sliding seat, a support cross arm, a bent clamping arm, a servo motor I, and a rotating shaft, rotational control of the adjustable clamping arm can be achieved. Therefore, when clamping the cylinder liner internally or externally, the clamping stroke can be increased to a certain extent, so as to be further adaptable to the clamping work of cylinder liners with larger or smaller diameters. By setting a telescopic adjusting mechanism composed of a multi-stage hydraulic telescopic rod and a connecting plate, and an internal clamping auxiliary support mechanism composed of a limiting sleeve, a central support column, a servo motor II, a worm, a worm wheel, a multi-groove rope wheel, a number of traction steel ropes, a number of inclined guide rails, a number of tension springs, a number of limiting top seats, a number of limiting internal support arms, and a number of spring shafts, clamping and limiting of the inner surface of the cylinder liner can be realized when machining the outer surface of the cylinder liner, improving the stability of the adjustable clamping arm. By setting an external clamping auxiliary support mechanism composed of a support II, a hydraulic telescopic rod, a limiting external support arm, and a support arm, clamping and limiting of the outer surface of the cylinder liner can be realized when machining the inner surface of the cylinder liner, improving the stability of the adjustable clamping arm.
