Description

Technical Field

[0001] The utility model belongs to the technical field of steel rolling, and particularly relates to a guide device for a diameter measuring instrument after fine rolling. Background Art

[0002] After the steel rolled piece is rolled out of the finishing mill, it needs to be measured by a diameter gauge when passing through the recovery section guide groove, and the feedback is given to the adjustment worker of the finishing mill to correct the size of the rolled piece. The violent shaking of the rolled piece when passing through the recovery section guide groove rubs the inner wall of the guide groove, causing vibration impact on the guide groove and the water beam used to install and fix the guide groove.

[0003] The diameter gauge is installed between two sections of recovery water beams. The traditional diameter gauge itself is equipped with an inlet guide groove and an outlet guide groove. The jitter and heat generated when the rolled piece passes through the inlet guide groove and the outlet guide groove of the diameter gauge are transferred to the diameter gauge, which is bound to affect the accuracy of the diameter gauge's measurement data and shorten the life of the diameter gauge's own electronic components. Therefore, it is imperative to improve the measurement accuracy of the diameter gauge and extend its service life. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a guide device for a diameter gauge after fine rolling. The diameter gauge and the guide groove of the recovery section maintain a non-contact state, ensuring that the jitter and heat generated when the rolled piece passes through the inlet guide groove and the outlet guide groove of the diameter gauge will not be directly transmitted to the diameter gauge, thereby avoiding the accuracy of the measurement data affected by the jitter and heat transfer and improving the service life of the rangefinder.

[0007] Furthermore, the first clamp assembly and the second clamp assembly have the same structure and both include a U-shaped clamp, wherein the upper and lower ends of the U-shaped clamp are radially engaged with the guide groove and the water beam, and a clamping handwheel for clamping the guide groove is provided on the upper end face of the U-shaped clamp, and a mounting block is provided on the water beam corresponding to the mounting position of the U-shaped clamp, and the lower end of the U-shaped clamp is connected to the mounting block via a mounting pin.

[0008] Furthermore, the center line of the rotating rod of the clamping hand wheel intersects perpendicularly with the center line of the mounting pin hole at the lower end of the U-shaped clamp, which can ensure the clamping effect.

[0009] Furthermore, the inlet guide groove and the outlet guide groove are both formed by two guide groove components arranged up and down and relatively buckled and spliced, and the two guide groove components arranged up and down are mutually clamped by staggered positioning blocks.

[0010] Furthermore, the upper end surfaces of the inlet water beam and the outlet water beam are both provided with guide groove positioning plates, and the guide groove positioning plates are provided with slots for cooperating with positioning blocks.
