Embodiment 1

[0044] In this embodiment, for a method for detecting the inclination of a rolling mill liner, see figure 1 , the method includes:

[0045] S101, based on laser ranging, obtain a reference point in the three-dimensional space where the rolling mill is located, and use the reference point as the origin to establish a three-dimensional coordinate system;

[0046] S102, based on laser ranging, in the three-dimensional coordinate system, obtain sample points of the surface of the lining plate to be measured of the rolling mill;

[0047] S103, fitting the sample points to obtain the fitted liner plane of the liner to be tested;

[0048] S104 , obtaining the inclination direction of the liner to be tested based on the relative positional relationship between the plane of the fitted liner and the central symmetry plane of the frame where the liner to be tested is located along the roll bearing direction.

[0049] In this embodiment, the laser tracker and Figures 4 to 6 The auxili...

Embodiment 2

[0130] In this embodiment, a point-contact plane offset tooling, refer to Figures 4 to 6 , the device includes:

[0131] A concave groove 1 for placing the reflector and a multi-point bracket 2 connected to the bottom of the concave groove.

[0132] As an optional implementation manner, the multi-point bracket includes three supporting feet distributed in an array. While ensuring stability, the contact area is reduced.

[0133] Optionally, the toes of the supporting feet are wedge-shaped structures. Further reduce the contact area and increase the stability.

Abstract

The invention discloses a rolling machine lining plate inclination detecting method and detecting tool and relates to the technical field of metallurgical equipment. Based on laser distance measuring,one reference point of a three-dimensional space where a rolling machine is located is obtained, and a three-dimensional coordinate system is set up with the reference point as an original point; based on laser distance measuring, in the three-dimensional coordinate system, a sample point of the surface of a lining plate, to be detected, of the rolling machine is obtained; the sample point is fitted, and a fitting lining plate plane of the lining plate to be detected is obtained; and based on the relative position relation between the fitting lining plate plane and the central symmetry face of a rack where the lining plate to be detected is located, the inclination direction of the lining plate to be detected is obtained. The detecting precision is higher, and the important reference is provided for evaluating rolling machine space precision problems such as the abrasion amount of the lining plate, the corrosion degree of a rolling machine body and the assembling precision of the lining plate.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a method for detecting the inclination of a rolling mill lining plate and a detection tool. Background technique [0002] The core process of hot rolling and some cold rolling production lines is the rolling process of the rolling mill. The inclination state of the rolling mill lining plate or the rolling mill limit surface is to evaluate the rolling mill space precision such as the wear amount of the rolling mill, the erosion degree of the rolling mill body, and the assembly accuracy of the rolling mill. important reference for the problem. [0003] At present, the existing measurement technology can only measure the upper and lower gaps of the lining plates on both sides of the roll with a simple size measuring instrument to judge whether the lining plates are inclined, and the detection accuracy is low. SUMMARY OF THE INVENTION [0004] The embodiments of th...
