[0002] Liners, as indispensable key components in mechanical equipment, are widely used in many important industrial fields such as mining, metallurgy, building materials, and power. The processing quality of liner plates directly affects their performance and the overall operating efficiency of the equipment. If the processing precision of the liner plates is insufficient, problems such as loose fit and uneven stress may occur during installation and use. This will not only shorten their service life but may also lead to increased vibration and energy consumption during equipment operation, and even cause safety accidents. Therefore, accurate positioning and secure clamping during the liner plate processing are crucial steps to ensure processing quality.

The lower end of the rotating rod 32 is in contact with the upper end of a set of movable plates 23. The lower end of the rotating rod 32 is fixed to the output end of the servo motor 35. Every two sets of toothed plates 34 mesh with a set of gears 33. Both sets of servo motors 35 are connected to the control panel 12.

The upper ends of the four sets of sliding blocks 39 are respectively fixed to the lower ends of the four sets of L-shaped plates 31. A shelf 11 is installed on the upper end of the workbench 1.

[0019] The specific settings and functions of this embodiment are described below. The workbench 1 serves as the basic support structure of the entire device, providing an installation reference and bearing platform for other components, ensuring the overall stability of the device. The placement rack 11 is fixedly installed on the upper surface of the workbench 1 for directly placing the liner to be processed. Its surface is flat and smooth to avoid scratching the bottom of the liner. The control panel 12 is installed at the front end of the workbench 1 and controls the cylinder 22 of the clamping mechanism 2 and the servo motor 35 of the positioning adjustment mechanism 3 through signal connection, thereby realizing the automated operation control of the device. Clamping mechanism 2: Two sets of fixed plates 21 are symmetrically fixedly installed on both sides of the workbench 1, serving as the fixed base for the clamping mechanism 2 and providing installation support for the cylinder 22 and the guide rail 24. Two sets of cylinders 22 are respectively installed on the upper ends of the two sets of fixed plates 21, and their extended ends are fixedly connected to one end of the fixed block 26 on the movable plate 23. The cylinder 22 receives the signal command from the control panel 12 and drives the movable plate 23 to achieve clamping or loosening action through telescopic movement, providing stable clamping power. Two sets of parallel guide rails 24 are installed on the upper end of each set of fixed plates 21 of the guide rail 24 to provide guidance for the sliding of the slide block 25 and ensure the linearity of the movement of the movable plate 23. The slide block 25 is slidably installed on the outer wall of the guide rail 24. The upper end of each two sets of slide blocks 25 is fixedly connected to the lower end of a set of movable plates 23. The slide block 25 cooperates with the guide rail 24 to restrict the movement of the movable plate 23 on a fixed trajectory, while reducing motion friction and making the movement of the movable plate 23 more stable. The two sets of movable plates 23 are set above the worktable 1 and are connected to the guide rail 24 through the slide block 25. They can move horizontally along the direction of the guide rail 24 under the drive of the cylinder 22 to clamp or loosen the liner on the placement rack 11. The fixing block 26 is installed on the upper end of the movable plate 23 and serves as the connection medium between the protruding end of the cylinder 22 and the movable plate 23, transmitting the driving force of the cylinder 22 to the movable plate 23. Positioning adjustment mechanism 3: There are four sets of L-shaped plates 31, with two L-shaped plates 31 symmetrically distributed on the movable plate 23 in each set. One end of each plate is equipped with a toothed plate 34, and the other end is used to contact and position the side of the liner. Precise positioning of liners of different specifications can be achieved by adjusting the position. Two sets of rotating rods 32 are respectively installed through the upper end of the two sets of movable plates 23. The lower end is fixedly connected to the output end of the servo motor 35. The upper end drives the gear 33 to rotate, which plays a role in power transmission. The gear 33 is installed on the outer wall of the rotating rod 32 and meshes with the two sets of toothed plates 34. It converts the rotational motion of the servo motor 35 into the linear motion of the toothed plate 34. The toothed plate 34 is fixed to one end of the L-shaped plate 31 and meshes with the gear 33. Under the drive of the gear 33, the L-shaped plate 31 moves along the guide groove 37 to achieve positioning adjustment. The servo motor 35 is installed at the lower end of the movable plate 23 and is connected to the control panel 12. It receives control signals and outputs precise rotational motion to provide power for positioning adjustment and ensure adjustment accuracy. An elongated hole 36 is formed at the upper end of the movable plate 23, providing sliding space for the elongated block 38 connected to the L-shaped plate 31, accommodating the position adjustment of the L-shaped plate 31. A guide groove 37 is formed at the upper end of the movable plate 23, providing guidance for the sliding block 39, ensuring that the L-shaped plate 31 moves smoothly along a fixed direction. The elongated block 38 is slidably installed inside the elongated hole 36, connecting the L-shaped plate 31 and the movable plate 23, and assisting in limiting the movement trajectory of the L-shaped plate 31. The sliding block 39 is slidably set inside the guide groove 37, with its upper end fixedly connected to the lower end of the L-shaped plate 31, so that the L-shaped plate 31 slides stably along the guide groove 37, ensuring positioning accuracy.

[0020] The operating method and working principle of this device are as follows: First, before starting the device, the control panel 12 is in the initial state, the cylinder 22 of the clamping mechanism 2 is in the retracted state, driving the two sets of movable plates 23 to the maximum spacing position; the four sets of L-shaped plates 31 of the positioning adjustment mechanism 3 are in the initial retracted position, reserving sufficient space for placing the liner. The operator places the liner to be processed on the placement rack 11 at the upper end of the worktable 1, completing the preparation work before processing; Afterwards, the operator sends control signals to the two sets of servo motors 35 through the control panel 12 according to the specifications and dimensions of the liner. After receiving the signal, the servo motors 35 start and drive the rotating rod 32 to rotate precisely. This drives the gear 33 fixed on the outer wall of the rotating rod 32 to rotate synchronously. Since the gear 33 meshes with the two sets of toothed plates 34, the rotational motion of the gear 33 is converted into the linear motion of the two sets of toothed plates 34. The two sets of toothed plates 34 move in opposite directions. The toothed plates 34 drive the L-shaped plate 31 fixed to them to move synchronously. The sliding block 39 at the lower end of the L-shaped plate 31 slides along the guide groove 37 on the movable plate 23. At the same time, the long block 38 slides along the long hole 36. The double guiding effect ensures that the L-shaped plate 31 moves smoothly. The four sets of L-shaped plates 31 gradually approach the edge of the liner until they make precise contact with the side of the liner, thus achieving the positioning of the liner. At this time, the control panel 12 controls the servo motor 35 to stop working, and the positioning adjustment is completed. Then, after positioning is completed, the operator sends a clamping signal to the two sets of cylinders 22 through the control panel 12. After receiving the signal, the cylinders 22 extend the piston rod and push the movable plate 23 to move through the fixed block 26 fixed to the piston rod. The slide 25 at the lower end of the movable plate 23 slides along the guide rail 24 on the fixed plate 21 to ensure that the movable plate 23 moves smoothly in a straight line. The two sets of movable plates 23 drive the positioning adjustment mechanism 3 on them to move synchronously towards the liner plate until the L-shaped plate 31 of the positioning adjustment mechanism 3 clamps the liner plate on the placement frame plate 11. After the preset clamping force is reached, the control panel 12 controls the cylinders 22 to stop moving, and the clamping and fixing are completed. Finally, after the liner plate has completed the processing operation in the positioning and clamping state, the operator sends a reset signal through the control panel 12. The cylinder 22 first retracts, driving the movable plate 23 and the positioning adjustment mechanism 3 to reset and release the liner plate. Then the servo motor 35 rotates in the opposite direction, driving the L-shaped plate 31 back to the initial position. The operator removes the processed liner plate, and the entire workflow ends.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
