[0007] When the low-pressure inner cylinder diaphragm sleeve needs to be cut, the auxiliary device is placed flat on the ground, the diaphragm sleeve is hung horizontally in the auxiliary device with the middle subface facing up, the screw of the auxiliary device is adjusted to move along the screw sleeve to level the horizontal middle subface of the diaphragm sleeve, and then the stress groove and stress hole position size lines are drawn on the flange of the middle subface of the diaphragm sleeve, and then the lines are processed.

[0008] In a preferred embodiment, long and short reinforcing ribs are welded between the outer wall of the vertical rib plate and the support plate.

[0009] Through the above technical solution, the stability of the equipment is improved by setting long and short reinforcing ribs.

[0010] In a preferred embodiment, a contact pad is fixedly installed on one side of the screw.

[0011] By the technical scheme, the contact pad is arranged to reduce damage of the screw rod to the outer wall of the partition plate.

[0012] In a preferred embodiment, the stud plate has a trapezoidal structure.

[0013] In a preferred embodiment, the screw rod is fixedly installed with a hand wheel on the side away from the contact pad.

[0014] By the technical scheme, the screw rod can be quickly rotated by the hand wheel.

[0015] In summary, due to the adoption of the above technical scheme, the low-pressure inner cylinder flange stress groove cutting auxiliary device is provided.

[0016] When the low-pressure inner cylinder partition sleeve needs to be cut, the auxiliary device is placed on the ground, the middle split surface of the partition sleeve is upwardly oriented and is horizontally hung in the auxiliary device, the screw rod is adjusted to move along the screw rod sleeve to level the middle split surface of the partition sleeve, after leveling, the stress groove and stress hole position and size lines are drawn on the flange of the middle split surface of the partition sleeve, and then the lines are processed.
