[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] like Figure 1-Figure 7 As shown, a vacuum device and method for high-temperature assembly of a transmission roller includes: a vacuum box 1, a feeding assembly and a heating movable seat 12,

[0037] A plurality of air outlets 8 are provided at the side end of the vacuum box 1 along the width direction, a plurality of conduits 3 are fixedly connected to the side end of the vacuum box 1 along the width direction, a numerical control device 4 is fixedly connected to the top of the vacuum box 1, and a box door 7 is cooperatively connected to the side end of the vacuum box 1 away from the conduit 3. The conduit 3 and the air outlet 8 are communicated with each other. The transmission roller 21 is placed in the vacuum box 1, and the box door 7 is closed. The box door 7 seals the inner wall of the vacuum box 1, and the air in the vacuum box 1 is sucked out through the existing equipment. The air in the vacuum box 1 passes through the air outlet 8 and the conduit 3 and is discharged. The vacuum box 1 is in a vacuum state, and the transmission roller 21 is assembled in the vacuum state, thereby preventing impurities in the air from affecting the assembly.

[0038] The feeding assembly is connected to the vacuum box 1, and the feeding assembly is connected to the power assembly. The feeding assembly is clamped and connected to the transmission roller 21. In order to ensure that the transmission roller 21 can load and unload materials more conveniently, the transmission roller 21 is installed on the feeding assembly, and the power assembly drives the feeding assembly to move, thereby achieving the effect of automatic loading and unloading of the transmission roller 21. When the transmission roller 21 is unloading, the power assembly can avoid the phenomenon that the heat of the transmission roller 21 causes harm to the human during manual operation;

[0039] The heating movable seat 12 is slidably connected to the bottom end of the CNC device 4, and the bottom end of the heating movable seat 12 is telescopically connected to the heating support plate 11. The bottom end of the heating support plate 11 is fixedly connected to the roller groove 23, and the roller groove 23 is connected with a clamping assembly. When the transmission roller 21 is in a vacuum environment in the vacuum box 1, the CNC device 4 drives the heating movable seat 12 to move, and the heating movable seat 12 drives the roller groove 23 to move through the heating support plate 11. The roller groove 23 is sleeved on the transmission roller 21. The CNC device 4 drives the roller groove 23 to operate for heating, and the roller groove 23 heats the transmission roller 21.

[0040] In some specific embodiments, the vacuum box 1 is fixedly connected to a temperature detector 9 at the side end near the air outlet 8, and several heating plates 10 are fixedly connected to the inner walls of both ends of the vacuum box 1 along the length direction. The vacuum box 1 is fixedly connected to a feeding plate 5 at the side end away from the conduit 3, and a rounded corner 6 is provided on the side end of the feeding plate 5. In order to avoid temperature difference in the vacuum box 1, which causes the heat heated by the roller groove 23 to be unable to be fully transferred to the transmission roller 21, the heating plate 10 on the inner wall of the vacuum box 1 is heated to increase the temperature in the vacuum box 1. The temperature detector 9 controls the operation of the heating plate 10 by detecting the temperature in the vacuum box 1, and controls the temperature in the vacuum box 1. Since there is a height difference between the vacuum box 1 and the ground, in order to ensure that the feeding assembly can stably enter the vacuum box 1, the feeding assembly is first transported to the feeding plate 5 along the rounded corner 6 with the transmission roller 21. The feeding plate 5 ensures that the feeding assembly and the bottom end of the vacuum box 1 are at the same height.

[0041] In some specific embodiments, the feeding assembly includes: a feeding trolley 17 and a clamping platform 22. The top of the feeding trolley 17 is fixedly connected to the clamping platform 22. The bottom of the feeding trolley 17 is fixedly connected to several fixed plates 24. The feeding trolley 17 is laterally provided with threaded holes 18. Roller grooves 23 are respectively provided at both ends of the bottom of the vacuum box 1. The fixed plates 24 are cooperatively connected with rollers 25. The rollers 25 are connected and moved along the inner wall of the roller groove 23. The top of the clamping platform 22 is cooperatively connected with the transmission roller 21. The threaded hole 18 is threadedly connected to the power component. The transmission roller 21 is installed on the clamping platform 22. The feeding trolley 17 is manually pushed to move, and the rollers 25 on the feeding trolley 17 move along the roller groove 23.

[0042] In some specific embodiments, a slide groove 28 is respectively provided at both ends of the clamping platform 22, and a limit plate 26 is clamped in the slide groove 28. The limit plate 26 is slidably connected to the slide groove 28, and the limit plate 26 is abutted against the transmission roller 21. An adjustment hole 29 is laterally provided on the limit plate 26, and an adjustment rod 27 is threadedly connected to the adjustment hole 29. The adjustment rod 27 is rotatably connected to the clamping platform 22 at one end close to the transmission roller 21. In order for those skilled in the art to better understand the clamping and fixing of the transmission roller 21 by the clamping platform 22, the transmission roller 21 is installed on the clamping platform 22, and the adjusting rod 27 is rotated. The adjusting rod 27 drives the limit plate 26 to slide along the inner wall of the slide groove 28 through the threaded connection with the adjusting hole 29. When the limit plate 26 abuts against the two ends of the transmission roller 21, the rotation of the adjusting rod 27 is stopped, and the adjusting rod 27 fixes the limit plate 26 through the threaded connection with the adjusting hole 29.

[0043] In some specific embodiments, the power assembly includes: a servo motor 2, a threaded rod 16, a limiting circular plate 19 and a connecting shaft 20. The threaded rod 16 is threadedly connected to the threaded hole 18. The threaded rod 16 is fixedly connected to the limiting circular plate 19 at the side end close to the servo motor 2. The diameter of the limiting circular plate 19 is larger than the diameter of the threaded rod 16. The servo motor 2 is fixedly connected to the side end of the vacuum box 1. The connecting shaft 20 is located between the servo motor 2 and the limiting circular plate 19. The two ends of the connecting shaft 20 are respectively fixedly connected to the servo motor 2 and the limiting circular plate 19. The threaded hole 18 opened on the feed cart 17 is aligned with the threaded rod 16 for installation. The servo motor 2 drives the threaded rod 16 to rotate through the connecting shaft 20. The threaded rod 16 drives the feed cart 17 to move through the threaded connection with the threaded hole 18, thereby realizing automatic loading of the transmission roller 21.

[0044] In some specific embodiments, the threaded rod 16 is fixedly connected to the guide rod 15 at the side end away from the servo motor 2. The diameter of the guide rod 15 is smaller than the inner diameter of the threaded hole 18. In order to facilitate better positioning of the feed cart 17 and the threaded rod 16, the threaded hole 18 is first aligned with the guide rod 15 to push the feed cart 17. The guide rod 15 passes through the threaded hole 18. When the threaded rod 16 and the threaded hole 18 are in contact, the servo motor 2 is started.

[0045] In some specific embodiments, the roller groove 23 is in the shape of a thread line. The roller groove 23 is sleeved on the outer wall of the transmission roller 21. The inner diameter of the roller groove 23 is larger than the diameter of the transmission roller 21. The shape of the roller groove 23 can better heat the transmission roller 21.

[0046] In some specific embodiments, the clamping assembly includes: a clamping movable seat 13, a robotic arm 14 and a clamping claw 30. The clamping movable seat 13 is at the bottom of the CNC device 4 and is movably connected to the CNC device 4. The robotic arm 14 is fixedly connected to the clamping movable seat 13. The robotic arm 14 is fixedly connected to the clamping claw 30. When the transmission roller 21 is heated to the assembly temperature, the CNC device 4 drives the clamping movable seat 13 to move, the clamping movable seat 13 drives the robotic arm 14 to move, and the robotic arm 14 controls the clamping claw 30 to clamp the bearing for assembly.

[0047] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0048] In the first step, the transmission roller 21 is installed on the feeding assembly, the transmission roller 21 is placed on the clamping table 22, and the adjusting rod 27 is rotated. The adjusting rod 27 drives the limit plate 26 to slide along the inner wall of the slide groove 28 through the threaded connection with the adjusting hole 29. When the limit plate 26 supports the two ends of the transmission roller 21, stop rotating the adjusting rod 27. The adjusting rod 27 fixes the limit plate 26 through the threaded connection with the adjusting hole 29.

[0049] In the second step, the transmission roller 21 loads the material, and the feed trolley 17 is manually controlled to move, and the roller 25 on the feed trolley 17 is rolled along the fillet 6 to the feeding plate 5. When the feed trolley 17 reaches the feeding plate 5, the threaded hole 18 on the feed trolley 17 is aligned with the guide rod 15 and moved. The guide rod 15 passes through the threaded hole 18. At the same time, the roller 25 rolls along the inner avoidance of the roller groove 23. When the threaded hole 18 and the threaded rod 16 contact, the feed trolley 17 is stopped and the servo motor 2 is driven. The servo motor 2 drives the connecting shaft 20 to rotate, and the connecting shaft 20 drives the limiting circular plate 19 and the threaded rod 16 to rotate. The threaded rod 16 drives the feed trolley 17 to move through the threaded connection with the threaded hole 18. The roller 25 continues to roll along the inner wall of the roller groove 23. When the feed trolley 17 moves to the target position, the servo motor 2 is stopped.

[0050] The third step is to vacuum the vacuum box 1. The box door 7 closes the vacuum box 1 and uses existing equipment to evacuate the air in the vacuum box 1. The air in the vacuum box 1 is discharged along the conduit 3 through the air outlet 8, and the transmission roller 21 is in a vacuum environment.

[0051] In the fourth step, the transmission roller 21 is assembled at high temperature. The CNC equipment 4 drives the heating movable seat 12 to move. The heating movable seat 12 drives the roller groove 23 to move through the heating support plate 11. The roller groove 23 is sleeved on the transmission roller 21. The CNC equipment 4 drives the roller groove 23 to operate for heating. The roller groove 23 heats the transmission roller 21. When the transmission roller 21 is at the assembly temperature, the CNC equipment 4 drives the clamping movable seat 13 to move. The clamping movable seat 13 drives the robotic arm 14 to move. The robotic arm 14 controls the clamping claw 30 to clamp the bearing for assembly.

[0052] The vacuum box 1 is in a vacuum state, and the transmission roller 21 is assembled in the vacuum state, which avoids the influence of impurities in the air on the assembly. The power component drives the feeding component to move, thereby realizing the effect of automatic loading and unloading of the transmission roller 21. When the transmission roller 21 is unloading, the power component can avoid the heat of the transmission roller 21 causing harm to the human during manual operation. The numerical control device 4 automatically performs high-temperature assembly of the transmission roller 21 by running the clamping component and the roller groove 23, thereby avoiding the phenomenon of errors in manual assembly and improving the accuracy of high-temperature assembly of the transmission roller 21.

[0053] Among them, in order to avoid temperature difference in the vacuum box 1, which causes the heat generated by the roller groove 23 to be unable to be fully transferred to the transmission roller 21, the heating plate 10 on the inner wall of the vacuum box 1 is heated to increase the temperature in the vacuum box 1. The temperature detector 9 controls the operation of the heating plate 10 by detecting the temperature in the vacuum box 1, and controls the temperature in the vacuum box 1, thereby ensuring that the roller groove 23 fully preheats the transmission roller 21 and improving work efficiency. The use of the guide rod 15 can position the feed cart 17 when loading, ensuring better manual operation of the feed cart 17. The roller groove 23 limits the roller 25, ensuring the stability of the feed cart 17 in moving in the vacuum box 1, and further enhancing the stability of the transmission roller 21 during assembly.

[0054] The above describes several embodiments of the present invention in detail, but the embodiments of the present invention are not limited to these and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
