[0065] The second fixing mechanism 420 includes a second gear 421, a friction surface 422, a second spring block 423 and a rotating sleeve 424; the rotating sleeve 424 can be rotatably sleeved on the mounting hole 415; the second gear 421 and the friction surface 422 are both fixedly arranged on the rotating sleeve 424; the second spring block 423 is arranged in the rotating sleeve 424, and the number of the second spring blocks 423 is three, and the second spring block 423 is used to clamp the other end of the valve body 300.

[0066] Initially, the positions of the first slide rail 230, the first movable platform 221 and the second movable platform 411 are adjusted, and the two ends of the valve body 300 are clamped by the fixed sleeve 211 and the rotating sleeve 424: first, one end of the valve body 300 is clamped by the second spring block 423 on the rotating sleeve 424, and the position of the second movable platform 411 is adjusted, and then the positions of the first slide rail 230 and the first movable platform 221 are adjusted, and the other end of the valve body 300 is clamped by the first spring block 212 on the fixed sleeve 211; or first, one end of the valve body 300 is clamped by the first spring block 212 on the fixed sleeve 211, and the positions of the first slide rail 230, the first movable platform 221 and the second movable platform 411 are adjusted, and one end of the valve body 300 is clamped by the second spring block 423 on the rotating sleeve 424.

[0067] When the first fixing mechanism 210 fixes the valve body 300, when the angle of the valve body 300 is an obtuse angle or a right angle, the valve body 300 will not contact the first movable platform 221; when the angle of the valve body 300 is an acute angle, the valve body 300 will contact the first movable platform 221, so that the fixing sleeve 211 cannot clamp one end of the valve body 300 through the first spring block 212, and there will be interference when the valve body 300 rotates. At this time, the rotating shaft 214 is extended by the air pump 217, thereby controlling the distance between the valve body 300 and the first movable platform 221, so that the fixing sleeve 211 can clamp one end of the valve body 300 through the first spring block 212, and the valve body 300 can rotate normally.

[0068] After the valve body 300 is fixed by the first fixing mechanism 210 and the second fixing mechanism 420, the first moving platform 221 is manually moved so that the first moving platform 221 is located near the limit of the first hydraulic cylinder 224, and the cylinder 414 is started to drive the pressure block 413 to abut against the friction surface 422, thereby limiting the rotation of the rotating sleeve 424 and thus limiting the rotation of the valve body 300; the hydraulic pump 222 is started so that the moving shaft 226 moves to contact with the first moving platform 221; thereby changing the meshing positions of the driven wheel 225 and the roller 227, and the roller 227 and the driving wheel 228, thereby changing the transmission ratio between the driven wheel 225 and the driving wheel 228, and detecting the rotation speed of the driven wheel 225 by electronic control, changing the liquid supply of the first hydraulic cylinder 224, and thereby changing the moving speed of the first moving platform 221, so that the valve body 300 can rotate smoothly.

[0069] When the valve body 300 needs to switch the angle for processing, the cylinder 414 is first started to drive the pressure block 413 to no longer abut against the friction surface 422, so that the rotating sleeve 424 can rotate; the second motor 417 is started, and the second gear 421 is driven to rotate through the first gear 412, and the second gear 421 drives the rotating sleeve 424 to rotate; the second motor 417 is started and the first motor 229 is started at the same time, and then the first hydraulic cylinder 224 drives the first moving platform 221 to move, and the cooperation of the first motor 229 and the second motor 417 drives the valve body 300 to rotate around the axis of the rotating sleeve 424, and after rotating to the processing angle, the first motor 229 and the second motor 417 are turned off, and the cylinder 414 is started to drive the pressure block 413 to abut against the friction surface 422, so as to limit the rotation of the rotating sleeve 424, thereby limiting the rotation of the valve body 300, and then the position of the tool 500 is switched to process the valve body 300.
