[0043] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following further elaborates on the embodiments of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of the present invention.

[0045] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the communication inside two elements; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0046] Refer to Figures 1 to 9 As shown, the ultra-high height and high load tapered roller precision grinding and forming processing equipment of the embodiment of the present invention includes a bottom shell 1. On both sides of the top of the bottom shell 1, a symmetrically arranged roller frame 1 3 and a roller frame 2 4 are respectively installed. Inside the bottom shell 1 and corresponding to the positions of the roller frame 1 3 and the roller frame 2 4, a driving component 2 for driving their movement is installed. On the side of the roller frame 1 3, a precisely grindable component 5 that can be rotationally adjusted is installed. On the top of the bottom shell 1 and corresponding to the position of the precisely grindable component 5, a roller pressing component 6 for positioning the tapered roller to be processed is installed.

[0047] Through the above technical solution, by setting the precisely grindable component 5 with adjustable angle and cooperating with the adjusting component 503 to precisely adjust the roller shaft 5013 of the precisely grindable component 5, the included angle between the two precisely grinding rollers 5014 can be flexibly changed.

[0048] To improve the flexibility and stability of the spacing adjustment of the precisely grinding rollers 5014, the driving component 2 includes a forward and reverse motor 201 fixedly connected to the side of the bottom shell 1. A threaded shaft 2011 is fixedly connected to the output shaft of the forward and reverse motor 201, and a reverse thread is provided on the threaded shaft 2011. Two symmetrically arranged threaded sleeves 2012 are threadedly connected to the threaded shaft 2011. The bottom of the threaded sleeve 2012 is fixedly connected with a limit slider 202. A limit chute 2021 matching the limit slider 202 is provided at the bottom of the inner wall of the bottom shell 1. By driving the threaded shaft 2011 to rotate by the forward and reverse motor 201, the synchronous reverse movement of the two threaded sleeves 2012 is realized by using the reverse thread, so as to quickly adjust the spacing of the precisely grinding rollers 5014 to meet the processing requirements of tapered rollers of different sizes; the cooperation between the limit slider 202 and the limit chute 2021 ensures the linearity of the movement of the threaded sleeve 2012, avoids the adjustment error caused by deviation, and improves the stability and accuracy of the spacing adjustment.

[0049] To improve the smoothness and positioning accuracy of the roller frame movement, positioning sliders 401 are fixedly connected to the bottoms of both the first roller frame 3 and the second roller frame 4. Positioning chutes 4011 matching the positioning sliders 401 are provided at the top of the bottom shell 1. Positioning balls 4012 that are in rolling connection with the inner walls of the positioning chutes 4011 are arranged on both sides of the positioning sliders 401. The cooperation between the positioning sliders 401 and the positioning chutes 4011 ensures the linearity of the movement trajectory of the roller frame. The positioning balls 4012 convert sliding friction into rolling friction, significantly reducing the movement resistance, making the roller frame move more smoothly, reducing wear at the same time, extending the service life of the equipment, and having higher positioning accuracy, which is beneficial to improving the processing quality.

[0050] To achieve precise adjustment and flexible adaptation of the angle of the fine grinding roller 5014, the fine grinding assembly 5 includes a rotating seat 501 fixedly connected to the side of the first roller frame 3. A rotating connecting block 5011 is rotatably installed on the rotating seat 501. A servo motor 5012 is fixedly connected to the side of the rotating connecting block 5011. A roller shaft 5013 is fixedly connected to the output shaft of the servo motor 5012. A fine grinding roller 5014 is fixedly connected to the roller shaft 5013. By driving the roller shaft 5013 to rotate through the servo motor 5012 and combining the rotational connection between the rotating seat 501 and the rotating connecting block 5011, the driving and angle adjustment of the fine grinding roller 5014 can be achieved. Therefore, it can adapt to the processing requirements of different taper conical rollers, improve the flexibility and adaptability of the equipment, and reduce the cost and time consumption caused by replacing the fine grinding roller 5014 or adjusting the processing line layout.

[0051] A sliding assembly 502 for limiting the roller shaft 5013 is installed on the second roller frame 4. An adjusting assembly 503 for driving the sliding assembly 502 is installed on one side of the sliding assembly 502. A limiting assembly 504 for limiting the sliding assembly 502 is installed on the other side of the sliding assembly 502. A positioning assembly 505 is installed on the second roller frame 4 at the position corresponding to the limiting assembly 504.

[0052] By setting the fine grinding assembly 5 with adjustable angle and cooperating with the adjusting assembly 503 to precisely adjust the angle of the roller shaft 5013 of the fine grinding assembly 5, the included angle between the two fine grinding rollers 5014 can be flexibly changed, enabling it to precisely match the processing requirements of different taper conical rollers, improving the adaptability and flexibility of the equipment, and reducing the cost and time consumption caused by replacing the fine grinding roller 5014 or adjusting the processing line layout.

[0053] To achieve the smooth movement of the sliding sleeve 5021 on the roller shaft 5013 and reduce wear, the sliding assembly 502 includes a sliding sleeve 5021 slidably arranged on the roller shaft 5013. Limiting balls 5022 that are in rolling connection with the roller shaft 5013 are arranged on the inner wall of the sliding sleeve 5021. A sliding groove 5023 matching the sliding sleeve 5021 is provided on the second roller frame 4.

[0054] In order to achieve precise adjustment and fixation of the position of the sliding sleeve 5021, the adjusting assembly 503 includes a threaded seat 5031 fixedly connected to the side of the second roller frame 4. A adjusting bolt 5032 is threadedly connected to the threaded seat 5031. The end of the adjusting bolt 5032 is rotatably connected to the side of the sliding sleeve 5021 through a bearing 5033. By rotating the adjusting bolt 5032 and utilizing the threaded connection between the threaded seat 5031 and the adjusting bolt 5032, precise movement of the sliding sleeve 5021 driving the roller shaft 5013 is achieved, thereby precisely adjusting the angle of the fine grinding roller 5014.

[0055] In order to prevent the sliding sleeve 5021 from shifting during movement, the limiting assembly 504 includes a positioning slide bar 5041 fixedly connected to the side of the sliding sleeve 5021. A positioning slide sleeve 5042 slidably connected to the positioning slide bar 5041 is provided at the side of the second roller frame 4 corresponding to the position of the positioning slide bar 5041.

[0056] In order to reliably position the sliding sleeve 5021 after angle adjustment, the positioning assembly 505 includes a mounting seat 5051 fixedly connected to the second roller frame 4. Connecting springs 5052 are fixedly connected to both sides of the top of the mounting seat 5051. The tops of the two connecting springs 5052 are fixedly connected through an operating block 5053. A sliding clamping rod 5054 is fixedly connected to the center of the bottom of the operating block 5053. A number of clamping grooves 5055 matching the sliding clamping rod 5054 are formed on the positioning slide bar 5041. After the angle adjustment is completed, under the elastic force of the connecting spring 5052, the sliding clamping rod 5054 is clamped into the corresponding positioning slide bar 5041 to reliably position the sliding sleeve 5021 and prevent it from moving during the processing, ensuring the processing accuracy.

[0057] The roller pressing assembly 6 includes a gantry 601 fixedly connected to the bottom shell 1. An electric cylinder 602 is installed on the gantry 601. A pressing roller 603 is fixedly connected to the output end of the electric cylinder 602;

[0058] When precisely grinding the tapered roller, in the present invention, by arranging the roller pressing assembly 6 above the fine grinding roller 5014 and utilizing the roller pressing action of the pressing roller 603, the stability of the roller during the fine grinding process is further enhanced, the vibration and offset of the roller during the processing are reduced, the uniform distribution and effective utilization of the abrasive are promoted, thereby improving the surface quality and dimensional accuracy of the tapered roller.

[0059] When the embodiment of the present invention is used, the tapered rotor to be processed is placed between the two fine grinding rollers 5014, and the fine grinding rollers 5014 are driven by the servo motor 5012, thereby realizing the fine grinding process of the tapered rotor.

[0060] The rotation of the screw shaft 2011 is driven by the forward and reverse motor 201. Since reverse threads are provided on the screw shaft 2011, the two screw sleeves 2012 will move synchronously in opposite directions. The limit sliders 202 at the bottom of the screw sleeves 2012 slide in the limit sliding grooves 2021 at the bottom of the inner wall of the bottom case 1, ensuring the linearity of the movement of the screw sleeves 2012 and avoiding adjustment errors caused by offset. As the screw sleeves 2012 move, the roller frames 1 3 and roller frames 2 4 connected thereto will also move accordingly, so as to quickly adjust the spacing of the precision grinding rollers 5014 to meet the processing requirements of different sizes of tapered rollers.

[0061] Positioning sliders 401 are fixedly connected to the bottoms of both the roller frame 1 3 and the roller frame 2 4. The positioning sliders 401 slide in the positioning sliding grooves 4011 at the top of the bottom case 1. The positioning balls 4012 arranged on both sides of the positioning sliders 401 are in rolling connection with the inner walls of the positioning sliding grooves 4011, converting sliding friction into rolling friction, significantly reducing the moving resistance, making the movement of the roller frames smoother, reducing wear at the same time, extending the service life of the equipment, and improving the positioning accuracy, which is beneficial to improving the processing quality.

[0062] The servo motor 5012 in the precision grinding assembly 5 drives the roller shaft 5013 to rotate. Combining the rotational connection between the rotating seat 501 and the rotating connection block 5011, the driving and angle adjustment of the precision grinding roller 5014 can be realized. When the angle of the precision grinding roller 5014 needs to be adjusted, the adjusting bolt 5032 in the adjusting assembly 503 rotates. Utilizing the threaded connection between the threaded seat 5031 and the adjusting bolt 5032, the sliding sleeve 5021 is driven to move on the roller shaft 5013. The limit balls 5022 on the inner wall of the sliding sleeve 5021 are in rolling connection with the roller shaft 5013, ensuring the smoothness of the movement and reducing wear.

[0063] The positioning slide rod 5041 on the side of the sliding sleeve 5021 slides in the positioning slide sleeve 5042 on the side of the roller frame 2 4, preventing the sliding sleeve 5021 from shifting during the movement. After the angle adjustment is completed, by pressing the operating block 5053 in the positioning assembly 505, the sliding latch 5054 is snapped into the card slot 5055 on the positioning slide rod 5041 under the elastic force of the connecting spring 5052, performing reliable positioning on the sliding sleeve 5021 and preventing it from moving during the processing, ensuring the processing accuracy.

[0064] When precision grinding the tapered roller, the electric cylinder 602 on the gantry 601 drives the pressure roller 603 to move downward, applying a stable pressure to the roller, reducing the vibration and offset of the roller during the processing, promoting the uniform distribution and effective utilization of the abrasive, thereby improving the surface quality and dimensional accuracy of the tapered roller.

[0065] The basic principles of the present invention have been shown and described above. The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention shall be included within the protection scope of the present invention.
