Description

Technical Field

[0001] The utility model belongs to the technical field of servo cylinder equipment in steel production, in particular to a tool for replacing a magnetic scale of a servo cylinder of a rolling mill in steel production. Background Art

[0002] A servo cylinder magnetic scale is a sensor based on magnetostriction, capable of high-precision linear displacement measurement. It is widely used in applications requiring precise position control, such as servo hydraulic cylinders. It is typically installed where it can accurately sense the piston's motion trajectory. For example, installing the scale inside the servo cylinder body prevents interference from the movement of other components, improving sensor protection and facilitating installation. During installation, the scale's connecting cable must be threaded through the top of the servo cylinder to connect to components such as the controller.

[0003] Servo cylinder magnetic scales are often damaged during use:

[0004] (1) Rolling mill vibration: During high-speed rolling, vibration may cause the core to deviate from the signal feedback stroke, resulting in core wear and forming steps, and contact with the magnetic head, causing the core to bend or break;

[0005] (2) Low equipment accuracy can also cause damage to the magnetic scale;

[0006] (3) Impure compressed air: If there are impurities in the compressed air, these impurities may enter the magnetic scale cylinder and grind with the magnetic core, causing damage to the magnetic scale;

[0007] (4) Long-term exposure to an environment containing impurities or oil-water mixtures may affect the contact resistance of the brushes, causing the displayed numbers to jump.

[0008] When the servo cylinder's magnetic scale is damaged, it needs to be removed and replaced promptly. Generally, replacing a servo cylinder's magnetic scale requires opening the cylinder's casing, locating the scale's installation location, loosening the screws or bolts securing the scale, and removing the old scale. Then, aligning the new scale with the installation location and inserting it into the servo cylinder for installation. However, servo cylinders are large devices, making opening their casing complex and inconvenient, reducing production efficiency. Utility Model Content

[0009] The purpose of the utility model is to provide a tool for replacing the magnetic scale of a rolling mill servo cylinder in steel production, so as to solve the problem that when replacing the servo cylinder magnetic scale, it is necessary to remove the equipment shell of the servo cylinder from the top of the rolling mill fixed frame and then remove the shell of the magnetic scale, which leads to complicated, inconvenient and low efficiency operation.

[0010] The utility model adopts the following technical solutions:

[0011] Tools for replacing the magnetic scale of the servo cylinder of the rolling mill in steel production, including:

[0012] The rotating rod is arranged horizontally and has a first through hole formed thereon; the first through hole is used for inserting the wire of the magnetic scale from bottom to top; the rotating rod is located at the top of the rolling mill fixed frame;

[0013] A rotating tube, the upper end of which is fixedly connected to the lower side of the rotating rod, and the rotating hole in its inner cavity is coaxially arranged with the first through hole; the inner cavity of the rotating tube is used to pass the wire of the magnetic scale from bottom to top and extend into the first through hole of the rotating rod, and the rotating tube is used to pass through the rolling mill fixed frame from top to bottom from the top of the rolling mill fixed frame and extend into the outer shell of the magnetic scale of the rolling mill servo cylinder;

[0014] The rotating sleeve is cylindrical, and its inner cavity is used for the conductor of the magnetic scale to pass from bottom to top and extend into the inner cavity of the rotating tube. It is fixedly connected to the lower end of the rotating tube and is used to be sleeved on the outer shell of the magnetic scale of the servo cylinder of the rolling mill. The rotating sleeve then rotates the outer shell of the magnetic scale and removes the magnetic scale for replacement.

[0015] The rotating rod is used to continuously rotate around the first through hole, thereby driving the rotating tube and the rotating sleeve to rotate, thereby rotating and opening the outer shell of the magnetic scale, and pulling out the magnetic scale through the wire. During the process of opening the outer shell of the magnetic scale, the wire of the magnetic scale is always in the rotating tube, so that the wire does not interfere with the opening process of the outer shell.

[0016] Furthermore, the rotating sleeve is a hexagonal cylindrical structure.

[0017] Furthermore, the rotating sleeve and the rotating tube are coaxially arranged.

[0018] The beneficial effects of the utility model are:

[0019] The utility model prevents the wires from interfering with or damaging the magnetic scale during the disassembly process by sequentially passing the wires of the servo cylinder magnetic scale through the rotating sleeve and the inner cavity of the rotating tube, that is, the rotating hole of the rotating tube and the first through hole of the rotating rod. During use, the rotating sleeve and the rotating tube are passed through the rolling mill fixed frame and extended into the outer shell of the magnetic scale of the rolling mill servo cylinder. The rotating sleeve is sleeved on the outer shell of the servo cylinder magnetic scale. The rotating rod is rotated by hand, thereby driving the rotating tube and the rotating sleeve to rotate, thereby completing the disassembly of the servo cylinder magnetic scale and pulling out the magnetic scale through the wires.

[0020] The utility model does not need to disassemble the shell of the servo cylinder during the process of replacing the servo cylinder magnetic scale, and the operation is simple and convenient, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model provides a tool for replacing the magnetic scale of the servo cylinder of the rolling mill in steel production, such as Figure 1 As shown, it includes a rotating rod 1, a rotating tube 2 and a rotating sleeve 3.

[0026] The rotating rod 1 is arranged horizontally, and a first through hole is opened on the rotating rod 1; the first through hole is used for extending the wire of the magnetic scale from bottom to top.

[0027] The upper end of the rotating tube 2 is fixedly connected to the lower side of the rotating rod 1, and the rotating hole in the inner cavity of the rotating tube 2 is coaxially arranged with the first through hole; the inner cavity of the rotating tube 2 is used to pass the wire of the magnetic scale from bottom to top and extend into the first through hole of the rotating rod 1, and the rotating tube 2 is used to pass through the rolling mill fixed frame from top to bottom from the top of the rolling mill fixed frame and extend into the outer shell of the magnetic scale of the rolling mill servo cylinder.

[0028] The rotating sleeve 3 is a cylindrical structure with an inner hexagon. The rotating sleeve 3 is coaxially arranged with the rotating tube 2. The inner cavity of the rotating sleeve 3 is used for the wire of the magnetic scale to pass through from bottom to top and extend into the inner cavity of the rotating tube 2. The rotating sleeve 3 is fixedly connected to the lower end of the rotating tube 2. The rotating sleeve 3 is used to be sleeved on the outer shell of the magnetic scale of the rolling mill servo cylinder; thereby, the rotating sleeve 3 rotates the outer shell of the magnetic scale and removes the magnetic scale for replacement.

[0029] The rotating rod 1 is used to continuously rotate around the first through hole, thereby driving the rotating tube 2 and the rotating sleeve 3 to rotate, thereby rotating and opening the outer shell of the magnetic scale, and pulling out the magnetic scale through the wire. During the process of opening the magnetic scale outer shell, the wire of the magnetic scale is always in the rotating tube 2, so that the wire does not interfere with the opening process of the outer shell.

[0030] The method of using the utility model is as follows:

[0031] Pass the wire of the magnetic scale through the rotating sleeve 3, then through the rotating tube 2, and finally through the first through hole of the rotating rod 1, and fix or grab the wire of the magnetic scale on the upper side of the first through hole, then pass the rotating sleeve 3 and the rotating tube 2 through the rolling mill fixed frame, and continue to move downward until it reaches the outer shell of the magnetic scale of the servo cylinder. At this time, the rotating rod 1 is located at the top of the rolling mill fixed frame. Use the rotating rod 1 to put the rotating sleeve 3 on the outer shell of the magnetic scale. At this time, rotate the rotating rod 1 to make the rotating sleeve 3 rotate continuously, and then remove the magnetic scale. Continuously move the tool upward and drive the magnetic scale upward until it is out of the servo cylinder.

[0032] The utility model passes the conductive wires of the servo cylinder magnetic scale through the first through-holes of the rotating sleeve 3, the rotating tube 2 and the rotating rod 1 in sequence, so as to avoid interference or damage to the conductive wires during the process of disassembling the magnetic scale. During use, the rotating sleeve 3 and the rotating tube 2 are passed through the rolling mill fixed frame and extended into the outer shell of the magnetic scale of the rolling mill servo cylinder. The rotating sleeve 3 is sleeved on the outer shell of the servo cylinder magnetic scale. The rotating rod 1 is rotated by hand, and then the rotating tube 2 and the rotating sleeve 3 are driven to rotate, thereby completing the disassembly of the servo cylinder magnetic scale and pulling out the magnetic scale through the conductive wires.

[0033] The utility model does not need to disassemble the shell of the servo cylinder during the process of replacing the servo cylinder magnetic scale, and the operation is simple and convenient, thereby improving production efficiency.
