DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] Referring to Figures 1 to 13 The application provides a technical scheme: a chain sleeve fine grinding device and fine grinding process, which comprises a device base 1, a transverse guide rail 2 is arranged at the top center position of the device base 1, and a group of slidable seats 3 is movably arranged on the transverse guide rail 2 and moves away from or close to each other along the axis direction of the transverse guide rail 2;

[0041] A group of position adjusting seats 4 is arranged at the top of the slidable seat 3, and a fixed guide rail 5 is movably connected to the position adjusting seat 4, and the group of position adjusting seats 4 moves away from or close to each other along the axis direction of the fixed guide rail 5;

[0042] The movement of the position adjusting seat 4 on the fixed guide rail 5 is extremely flexible, and they can freely move away from or close to each other along the axis direction of the fixed guide rail 5. In terms of structural details, the fixed guide rail 5 adopts a high-precision linear guide rail, the surface of which is subjected to special grinding and hardening treatment, so as to not only have a very low friction coefficient, thereby effectively reducing the resistance of the position adjusting seat 4 during movement, but also have very high wear resistance and straightness, thereby ensuring the stability and accuracy of the position adjusting seat 4 during movement. The connecting part of the position adjusting seat 4 and the fixed guide rail 5 is provided with a specially designed sliding block, and the sliding block is internally provided with a rolling bearing structure, thereby further reducing the friction and ensuring the close fit between the position adjusting seat 4 and the guide rail, thereby preventing shaking and deviation.

[0043] The system adopts an advanced ball screw transmission mechanism driven by a servo motor to drive the position adjusting seat 4 to move. The servo motor has the characteristics of fast response speed and high control precision, and can accurately control the movement distance and speed of the position adjusting seat 4 according to the preset program. The ball screw transmission mechanism efficiently converts the rotary motion of the motor into the linear motion of the position adjusting seat 4, and has high transmission efficiency and accurate positioning precision, thereby meeting the requirements of high-precision machining. In terms of control, the device is provided with an advanced numerical control system, and the operator can easily input the required position adjusting parameters through the man-machine interface. The numerical control system will accurately control the operation of the servo motor according to these parameters, thereby realizing the accurate positioning of the position adjusting seat 4.

[0044] A slanted pressure plate 6 is rotatably connected to the position adjusting seat 4, and a structure composed of a first electric push rod 7 and a rotating mounting seat 8 is arranged between the slanted pressure plate 6 and the position adjusting seat 4 to support the slanted pressure plate 6, and the first electric push rod 7 applies a pushing force to the back surface of the slanted pressure plate 6.

[0045] The one end of the rotating mount 8 is connected with the adjusting seat 4 through a pin shaft, and the other end is connected with the fixed end of the first electric push rod 7. This design allows the rotating mount 8 to rotate on the adjusting seat 4 by a certain angle, thereby skillfully cooperating with the extension of the first electric push rod 7 and accurately controlling the inclination angle of the inclined pressure plate 6. The first electric push rod 7 is internally provided with a high-precision displacement sensor, which can feedback the extension length of the push rod in real time. When the operator inputs the target inclination angle of the inclined pressure plate 6 in the control system, the control system will quickly calculate the required extension length of the first electric push rod 7 according to the built-in algorithm and send accurate instructions to it.

[0046] When the chain sleeve specification changes, the equipment control system first adjusts the position of the adjusting seat 4 on the fixed guide rail 5 to change the distance between the two inclined pressure plates 6. Then, by controlling the extension of the first electric push rod 7, the inclination angle of the inclined pressure plate 6 is changed, so that the inclined pressure plate 6 can perfectly match the outer contour of the chain sleeve. For example, when processing large-diameter chain sleeves, the adjusting seats 4 move away from each other to increase the distance between the two inclined pressure plates 6; at the same time, the first electric push rod 7 is extended to push the inclined pressure plate 6 to tilt outward, increasing the contact area with the chain sleeve and providing more stable support. When processing small-diameter chain sleeves, the adjusting seats 4 move closer to each other, the first electric push rod 7 shortens, and the inclined pressure plate 6 tilts inward to accurately adapt to the sleeve size.

[0047] In addition, the surface of the inclined pressure plate 6 is pasted with a layer of high-wear-resistant and high-toughness rubber buffer layer. This design not only increases the friction between the inclined pressure plate 6 and the chain sleeve, preventing the sleeve from slipping during processing and affecting the processing precision, but also buffers the impact of the chain sleeve while avoiding scratching the surface of the sleeve, ensuring the processing quality of the product in all directions.

[0048] The adjusting seat 4 is rotatably connected with the inclined pressure plate 6, and a structure composed of the first electric push rod 7 and the rotating mount 8 is arranged between the inclined pressure plate 6 and the adjusting seat 4 to support the inclined pressure plate 6. The first electric push rod 7 applies a pushing force to the back of the inclined pressure plate 6. The rotating connection of the inclined pressure plate 6 adopts a high-precision bearing, which can ensure smooth rotation of the inclined pressure plate 6 and reduce wear during operation, prolonging the service life of the equipment.

[0050] The fixed guide rail 5 is rotatably connected with the first reverse thread screw rod 9, and the adjusting seat 4 is provided with a transverse plate screw-connected with the first reverse thread screw rod 9.

This sliding design not only ensures the movement accuracy of the movable mounting seat 15, but also greatly reduces the friction resistance in the movement process, prolonging the service life of the equipment.
