Description

Technical Field

[0001] The utility model relates to the technical field of ring rolling machine roller positioning, in particular to a vertical ring rolling machine roller rolling positioning device. Background Art

[0002] Vertical ring rolling machines are widely used in many industrial fields such as machinery, automobiles, trains, ships, petrochemicals, aviation, aerospace, atomic energy, wind power generation, etc.

[0003] The working principle of the vertical ring rolling machine is based on the relative movement of the driving wheel and the driven wheel. When the driving wheel rotates, the ring body rotates accordingly, and the driven wheel applies pressure to the surface of the ring body. During the rolling process of the ring rolling machine, in order to prevent the ring from swinging, a pair of holding rollers are used to apply force to the ring. However, after long-term use, the holding rollers need to be cleaned or replaced to ensure the processing quality of the ring.

[0004] Most of the existing vertical ring rolling mills use an adjustable mechanism for roller positioning units, which is convenient for adjustment according to the rolling specifications of the rings. However, most of the adjustable rollers are fixedly installed on the vertical workbench through a connecting mechanism. When the rollers are replaced or cleaned later, the disassembly process is cumbersome and time-consuming, which affects the use of the equipment. Therefore, those skilled in the art provide a vertical ring rolling mill roller rolling positioning device to solve the problems raised in the above background technology. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a vertical ring rolling machine roll rolling positioning device to solve the problem that most of the rolls in the existing equipment are fixedly installed on the vertical workbench through a connecting mechanism, and when the rolls are replaced or cleaned at a later stage, the disassembly process is cumbersome and time-consuming, which affects the use of the equipment.

[0007] Preferably, the rotating shaft is rotatably engaged with the vertical workbench.

[0008] Preferably, a rotating wheel is installed at one end of the screw rod adjacent to the rotating part, and a nut is threadedly connected to the screw rod. When the roller body is in use, the position of the roller bracket and the roller body can be adjusted by rotating the screw rod by the rotating wheel, and the setting of the nut allows the screw rod to be fixed when the nut is squeezed with the first half threaded sleeve and the second half threaded sleeve to prevent the screw rod from loosening.

[0009] Preferably, the pressure spring is rotatably sleeved with the rotating shaft, the limiting sleeve is rotatably sleeved with the rotating shaft, one end of the pressure spring is in pressure contact with the support ring, and one end of the limiting sleeve is in pressure contact with the pressure ring. Under the action of the pressure spring, the limiting sleeve is sleeved with the closed ends of the first half threaded sleeve and the second half threaded sleeve until it is in pressure contact with the pressure ring, thereby fixing it to prevent the first half threaded sleeve and the second half threaded sleeve from separating.

[0010] Preferably, the roller bracket is plugged into the vertical workbench through a fixed shaft, and the roller bracket is rotatably connected to the roller body. When the roller bracket is disassembled, the limit sleeve is squeezed toward the support ring so that the second half of the threaded sleeve can be flipped.
