Description

Technical Field

[0001] This invention relates to a rolling pressure head box laser online leveling system and leveling method. Background Technology

[0002] The sensor used to measure rolling force is called the pressure head. It directly bears the rolling force and converts the force value into an electrical signal output. The pressure head is installed inside a pressure head box, which is fixed to the bottom inner side of the rolling mill stand. To ensure the accuracy of the measured force value, the contact surface between the pressure head box and the pressure head must be flat. However, due to the influence of the working environment, the inside of the pressure head box contains corrosive substances such as cooling water, dairy products, and sludge. Over time, these substances can accumulate and cause corrosion, material buildup, and localized deformation inside the pressure head box, affecting the measurement accuracy of the rolling force pressure head.

[0003] At the steel rolling mill, the pressure head box needs to be cleaned regularly, and those severely corroded require grinding and leveling. Currently, grinding and leveling the pressure head box mainly relies on manual operation, which is labor-intensive and makes it difficult to guarantee the leveling accuracy. Summary of the Invention

The frame body includes a first side frame and a second side frame. The first adjusting component connects the first side frame and the second side frame and is telescopically movable to move the first side frame and the second side frame in a first direction to change the length of the frame body in the first direction. Each of the first side frame and the second side frame includes a fixed segment disposed along a second direction and a sliding segment connected to the fixed segment. The sliding segment is movable relative to the fixed segment to change the length of the frame body in the second direction. The second adjusting component is used to fix the sliding segment to the target pressure head box. The fixed frame is determined according to the length of the frame body in the first direction and is adapted to be installed on the target pressure head box. The leveling component is used to level the fixed frame.

[0030] The leveling system includes a mounting component 2, a sliding component 3, and a leveling component 4. The mounting component 2 is installed on the target pressure head box 1, and the leveling component 4 is connected to the mounting component 2. The leveling component 4 can move relative to the mounting component 2 under the action of the sliding component 3 to realize information collection and leveling processing of the target pressure head box 1.

[0031] For details, please refer to Figure 2 and Figure 3 The mounting component 2 includes a mounting frame 21, a leveling component 22, a first adjusting component 23, and a second adjusting component 24.

The first adjusting member 23 can extend and retract to move the first frame 2111 and the second frame 2112 in a first direction (the direction of arrow Y) to change the length of the frame 211 in the first direction. Both the first frame 2111 and the second frame 2112 include a fixed section 2113 and a sliding section 2114 connected to the fixed section 2113, which can move relative to the fixed section 2113 to change the length of the frame 211 in the second direction.

The lead screw 411 rotates under the action of an external force to convert the rotational motion into linear motion of the sliding frame 42 on the lead screw 411, so that the sliding frame 42 can move along the lead screw 411 in the first direction to drive the scanning device 43 and the leveling device 44 to move in the first direction; while the mounting frame 41 can move in the second direction under the action of the sliding assembly 3 to drive the scanning device 43 and the leveling device 44 to move in the second direction.

[0035] As described above, the leveling system further includes a drive assembly 5, which includes a first drive member 51 and a second drive member 52 disposed on the mounting frame 41.

The control unit can perform point cloud modeling based on the height direction coordinates, the coordinate information in the first direction, and the coordinate information in the second direction obtained by the scanning device 43, the first encoder, and the second encoder to obtain the flatness information of the entire surface to be processed. The leveling device 44 can level the surface to be processed. It should be explained that, in this embodiment, the working principle of the first encoder and the second encoder is to convert the position of linear motion into digital signal output; while the information acquisition, point cloud modeling and algorithms between the scanning device 43, the leveling device 44, the first encoder and the second encoder, and the control unit are all mature technologies, and will not be described in detail here.
