[0019] The first step: According to the size of the chain sleeve to be precision - ground, adjust the distance between the two movable mounting seats, and grind the chain sleeve by rotating the grinding roller.

[0020] Step 2: According to the length of the chain sleeve, adjust the position of the sliding seat on the transverse guide rail, and drive the two adjustment seats to move on the fixed guide rail through the rotation of the first positive and negative screw rods, so as to change the distance between the two inclined pressure plates to adapt to chain sleeves of different diameters.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. According to the length of the chain sleeve, the position of the sliding seat on the transverse guide rail is adjusted, and the distance between the two oblique pressure plates is changed to adapt to chain sleeves of different diameters. At the same time, the piston rod of the first electric push rod can push the oblique pressure plate to rotate on the adjustment seat to change the relative angle between the two oblique pressure plates to better support the chain sleeve. The position of the sliding seat can be adjusted according to the length of the chain sleeve, and the distance and relative angle between the oblique pressure plates can be changed to adapt to chain sleeves of different diameters. It shows strong versatility and can meet the support requirements of chain sleeves of various specifications, thereby improving the scope of application of the device.

[0024] 2. The miter plate buffers the fall of the chain bushing.

Then the chain bushing falls on the oblique pressure plate. The buffer plate and the oblique pressure plate are supported on all sides of the chain bushing to achieve buffering of the chain bushing. The miter plate can buffer the falling chain bushing, reduce the impact force when the bushing falls, and avoid damage to the chain bushing due to direct impact, thereby protecting the integrity and performance of the chain bushing and helping to extend its service life. The buffer plate and the oblique pressure plate are jointly supported on all sides of the chain bushing to achieve all-round buffering and support for the chain bushing, making the chain bushing more stable during the falling process, further reducing the position offset or shaking caused by the impact force, and facilitating the subsequent precise positioning and processing of the chain bushing.

[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 13 Figures 1 to 13 , the present invention provides a technical solution: a chain sleeve fine grinding device and a fine grinding process, including an equipment base 1. At the center position of the top of the equipment base 1, a transverse guide rail 2 is provided. A set of slidable seats 3 are movably installed on the transverse guide rail 2. The slidable seats 3 are located within the transverse guide rail 2 and move away from and close to each other along the axis direction of the transverse guide rail 2;

[0041] A set of positioning seats 4 are provided on the top of the slidable seat 3. A fixed guide rail 5 movably connected to the positioning seats 4 is provided on the top of the slidable seat 3. The set of positioning seats 4 move away from and close to each other along the axis direction of the fixed guide rail 5 on the fixed guide rail 5;

[0042] The movement of the positioning seats 4 on the fixed guide rail 5 is extremely flexible. They can freely move away from and close to each other along the axis direction of the fixed guide rail 5. From the perspective of structural details, the fixed guide rail 5 adopts a high-precision linear guide rail, and its surface has been specially ground and hardened. It not only has an extremely low friction coefficient, which can effectively reduce the resistance when the positioning seats 4 move, but also has extremely high wear resistance and straightness, ensuring the stability and accuracy of the positioning seats 4 during the movement process. At the connection part between the positioning seats 4 and the fixed guide rail 5, specially designed sliders are equipped. The inside of the sliders adopts a rolling bearing structure, which further reduces the friction force and at the same time ensures the close fit between the positioning seats 4 and the guide rail, preventing shaking and deviation.

[0043] To drive the positioning seats 4 to move on the fixed guide rail 5, the system adopts an advanced ball screw drive mechanism driven by a servo motor. The servo motor has the characteristics of fast response speed and high control precision, and can accurately control the moving distance and speed of the positioning seats 4 according to the preset program. The ball screw drive mechanism efficiently converts the rotational motion of the motor into the linear motion of the positioning seats 4. Its transmission efficiency is high and the positioning accuracy is accurate, which can meet the requirements of high-precision machining. In terms of control, the equipment is equipped with an advanced numerical control system. The operator can easily input the required positioning parameters through the human-machine interface, and the numerical control system will accurately control the operation of the servo motor according to these parameters, so as to achieve the precise positioning of the positioning seats 4.

[0044] A slant receiving pressure plate 6 is rotatably connected to the positioning seat 4. A structure composed of a first electric push rod 7 and a rotary mounting seat 8 is provided between the slant receiving pressure plate 6 and the positioning seat 4 for support. The first electric push rod 7 applies a thrust to the back surface of the slant receiving pressure plate 6.

[0045] One end of the rotary mounting seat 8 is connected to the position adjusting seat 4 through a pin shaft, and the other end is connected to the fixed end of the first electric push rod 7. This design enables the mounting seat 8 to rotate at a certain angle on the position adjusting seat 4, thus cleverly cooperating with the telescopic movement of the first electric push rod 7 to accurately control the tilting angle of the inclined pressure receiving plate 6. The first electric push rod 7 is internally equipped with a high-precision displacement sensor, which can real-time feedback the telescopic length of the push rod. When the operator inputs the target tilting angle of the inclined pressure receiving plate 6 into the control system, the control system will quickly calculate the required telescopic length of the first electric push rod 7 according to the built-in algorithm and send an accurate instruction to it.

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

[0047] In addition, a layer of high-wear-resistant and high-toughness rubber buffer layer is pasted on the surface of the inclined pressure receiving plate 6. This design not only increases the friction force between the inclined pressure receiving plate 6 and the chain sleeve, preventing the sleeve from sliding during the processing and affecting the processing accuracy, but also can buffer the impact of the chain sleeve while avoiding scratching the surface of the sleeve, comprehensively ensuring the processing quality of the product.

[0048] The inclined pressure receiving plate 6 is rotatably connected to the position adjusting seat 4, and a structure composed of the first electric push rod 7 and the rotary mounting seat 8 is provided between the inclined pressure receiving plate 6 and the position adjusting seat 4 for support, and the first electric push rod 7 applies a thrust to the back of the inclined pressure receiving plate 6. The rotary connection of the inclined pressure receiving plate 6 adopts a high-precision bearing, which can not only ensure the smooth rotation of the inclined pressure receiving plate 6, but also reduce wear during operation and extend the service life of the equipment.

[0049] Rotary mounting seats 8 are provided at both the end of the piston rod and the other end of the first electric push rod 7, and the rotary mounting seats 8 are respectively fixedly installed on the back of the inclined pressure receiving plate 6 and the top of the position adjusting seat 4.

[0050] A first left-right threaded lead screw 9 is rotatably connected to the fixed guide rail 5, and a transverse plate threadedly connected to the first left-right threaded lead screw 9 is provided inside the position adjusting seat 4. By rotating the first left-right threaded lead screw 9, forces of moving away from each other and approaching each other are applied to the position adjusting seat 4.

[0051] A first left - right threaded lead screw 9 is rotatably connected to the fixed guide rail 5. A transverse plate that is threadedly connected to the first left - right threaded lead screw 9 is provided inside the position - adjusting seat 4. By rotating the first left - right threaded lead screw 9, forces that move away from and close to each other are exerted on the position - adjusting seat 4. At both ends of the first left - right threaded lead screw 9, threads with different helix directions are respectively used. When the lead screw rotates driven by a driving device, the transverse plate that is in threaded cooperation with it will produce relative movement along the axial direction of the lead screw due to the difference in the helix direction of the threads, thereby realizing the precise displacement of the position - adjusting seat 4 along the axis of the fixed guide rail 5, moving closer to or away from each other.

[0052] A buffer plate 10 is provided at the top of the fixed guide rail 5. A cavity is provided at the position of the position - adjusting seat 4 corresponding to the buffer plate 10.

[0053] Stepping motors 11 are provided at both ends of the transverse guide rail 2. A second left - right threaded lead screw 12 is fixedly installed on the output shaft of the stepping motor 11. The second left - right threaded lead screw 12 is threadedly connected to the slidable seat 3.

[0054] The bottom of the transverse guide rail 2 is supported by side supports 13, and the side supports 13 are fixedly installed on the side of the transverse guide rail 2.

[0055] On the top of the equipment base 1, a large guiding frame 14 is provided. Two movable mounting seats 15 are slidably installed on the large guiding frame 14. A grinding mechanism 16 is movably installed on the movable mounting seats 15. Second electric push rods 17 are provided on both sides of the grinding mechanism 16, and the end of the piston rod of the second electric push rod 17 is fixedly installed on the side of the grinding mechanism 16.

[0056] On the top of the equipment base 1, a large guiding frame 14 is provided. With its strong material and reasonable frame design, the large guiding frame 14 provides stable support for the upper structure of the equipment. Two high - precision slide rails are carefully designed on the large guiding frame 14. Two movable mounting seats 15 achieve smooth and precise sliding on the slide rails through matching sliders. This sliding design not only ensures the movement accuracy of the movable mounting seats 15 but also greatly reduces the frictional resistance during the movement process and extends the service life of the equipment.

[0057] A corrugated water supply pipe 18 is provided at the top of the grinding mechanism 16. The corrugated water supply pipe 18 is connected to the water tank on the equipment base 1. The water outlet end of the corrugated water supply pipe 18 is connected to a water distribution pipe 19. One water outlet end of the water distribution pipe 19 is provided with a water spraying mechanism 20. The other water outlet end of the water distribution pipe 19 is connected to another corrugated water supply pipe 18. This corrugated water supply pipe 18 is installed on another corrugated water supply pipe 18 and is connected to another water spraying mechanism 20.

[0058] At the top of the grinding mechanism 16, there is a corrugated water supply pipe 18. With its characteristics of being bendable and stretchable, it smoothly delivers water to the designated position while not affecting the flexible movement of the grinding mechanism 16. The water tank on the equipment base 1 is connected to the corrugated water supply pipe 18, and the water tank provides a stable water source reserve for the entire cooling water supply system. The water outlet end of the corrugated water supply pipe 18 is connected to a water distribution pipe 19. The water distribution pipe 19 adopts a split-flow design and can evenly distribute the water flow from the corrugated water supply pipe 18 to different branches

[0059] The position of the water spraying mechanism 20 corresponds to the position of the grinding roller on the grinding mechanism 16, and the water outlet of the water spraying mechanism 20 corresponds radially to the grinding roller on the grinding mechanism 16.

[0060] At the central positions on both sides of the grinding mechanism 16, there are inner fixing rings 21. An outer rotatable ring 22 is rotatably connected to the outside of the inner fixing rings 21. An inclined connecting plate 23 is fixedly installed on the outer rotatable ring 22. A fixing strip 24 is fixedly installed on the side of the inclined connecting plate 23. A locking bolt 25 is threadedly connected to the fixing strip 24, and the locking bolt 25 supports at the corresponding position on the outer wall of the inner fixing ring 21.

[0061] The inclined connecting plate 23 is arranged radially along the grinding roller of the grinding mechanism 16, and the inclined connecting plate 23 and the grinding mechanism 16 are coaxially arranged.

[0062] A chain sleeve precision grinding equipment and a precision grinding process include the following steps:

[0063] The first step: According to the size of the chain sleeve to be precision ground, adjust the distance between the two movable mounting seats 15, and grind the chain sleeve by rotating the grinding roller.

[0064] The second step: According to the length of the chain sleeve, adjust the position of the slidable seat 3 on the transverse guide rail 2. By rotating the first right and left threaded lead screw 9, drive the two adjusting seats 4 to move on the fixed guide rail 5, so as to change the distance between the two inclined pressure receiving plates 6 to adapt to chain sleeves of different diameters.

[0065] The third step: During the process of the chain sleeve falling, buffer the falling of the chain sleeve through the inclined connecting plate 23. Then the chain sleeve falls on the inclined pressure receiving plate 6, and then take away the chain sleeve.

[0066] Working principle:

[0067] The first step: According to the required size of the chain sleeve to be precisely ground, adjust the distance between the two movable mounting seats 15, so as to realize the distance between the two grinding mechanisms 16, and control the distance between the grinding rollers on the two grinding mechanisms 16, ensuring that the chain sleeve can be placed between the two grinding mechanisms 16, and the distance between the grinding rollers of the two grinding mechanisms 16 is less than the diameter of the chain sleeve. Through the rotation of the grinding rollers, the chain sleeve is ground. When the grinding rollers are working, the water tank supplies water to the corrugated water supply pipe 18, and the driving device applies a thrust to the water flow. The water flow enters the water distribution pipe 19 and then enters the next corrugated water supply pipe 18, and then enters the next water spraying mechanism 20. The two water spraying mechanisms 20 spray water on the grinding rollers of the grinding mechanism 16 respectively to cool the grinding rollers. And during the movement of the grinding mechanism 16, the corrugated water supply pipe 18 can deform to adapt to the movement of the movable mounting seat 15 and the grinding mechanism 16. After the chain sleeve is ground, move the movable mounting seat 15 and the grinding mechanism 16 in the reverse direction. The two movable mounting seats 15 and the grinding mechanism 16 move in opposite directions, and the chain sleeve can fall off.

[0068] The second step: According to the length of the chain sleeve, adjust the position of the slidable seat 3 on the transverse guide rail 2. The output shaft of the stepping motor 11 drives the rotation of the second left-right threaded screw 12. Through the rotation of the second left-right threaded screw 12, drive the two positioning seats 4 to move closer to or away from each other, ensuring that the structure on the slidable seat 3 can support at the corresponding position of the chain sleeve. Drive the two positioning seats 4 to move on the fixed guide rail 5 through the rotation of the first left-right threaded screw 9, so as to change the distance between the two inclined pressure receiving plates 6 to adapt to chain sleeves of different diameters. At the same time, the piston rod of the first electric push rod 7 can push the inclined pressure receiving plate 6 to rotate on the positioning seat 4 to change the relative angle between the two inclined pressure receiving plates 6 to better support the chain sleeve.

[0069] The third step: During the process of the chain sleeve falling, it will contact the inclined connecting plate 23. The inclined connecting plate 23 buffers the falling of the chain sleeve. At the same time, the angle of the inclined connecting plate 23 can be changed by the rotation of the outer rotatable ring 22 on the inner fixed ring 21. Change the position of the inclined connecting plate 23 on the grinding roller of the grinding mechanism 16, and fix the rotated inclined connecting plate 23 by screwing the locking bolt 25. The locking bolt 25 presses on the inner fixed ring 21 to realize the fixation of the fixing strip 24 and the inclined connecting plate 23, ensuring the stability of the inclined connecting plate 23. When the chain sleeve falls, it presses on the inclined connecting plate 23, and the inclined connecting plate 23 deforms to buffer the pressure of the chain sleeve falling. Then the chain sleeve falls on the inclined pressure receiving plate 6 again. The buffer plate 10 and the inclined pressure receiving plate 6 support around the chain sleeve to realize the buffering of the chain sleeve, and then take away the chain sleeve.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
