Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller rounding technology, and in particular to an automatic loading and unloading machine for roller rounding. Background Technology
[0002] Roller rounding equipment is a key piece of equipment in the bearing manufacturing industry. As the core component of a bearing, the quality of the rounding at both ends of the roller directly affects the bearing's load capacity and service life. With the advancement of industrial automation, traditional manual operation mode can no longer meet the requirements of modern manufacturing industry for efficiency, precision and flexible production. In view of the characteristics of rollers with diverse specifications and complex processing technology, developing a special equipment that integrates automated loading and unloading, multi-variety compatibility and high-precision processing has become an important technical direction for improving the level of intelligent bearing manufacturing.
[0003] Existing roller chamfering equipment mostly adopts a single-machine manual operation mode. Its mechanical structure typically includes a horizontal lathe body, a single-axis chuck fixture, and a simple feed device. During processing, the rollers must be manually placed one by one into the fixture positioning slot. After manually rotating the chuck to complete the chamfer on one side, the workpiece is then manually flipped to process the other side. This technical solution relies on manual intervention. Its core principle is to achieve a simple coordination between the tool feed and the workpiece rotation through mechanical transmission. It lacks workpiece posture adjustment and multi-station coordination capabilities. The equipment layout often adopts a side-by-side arrangement of the machine tool and the operating table.
[0004] However, existing technologies have significant drawbacks. Manual loading and unloading leads to low production efficiency. Each machine requires a dedicated operator, and each person can only complete the double-sided processing of about 50-80 rollers per hour. Furthermore, due to the large variation in accuracy of manual clamping and positioning, frequent dimensional calibration is required, further reducing the effective operating time of the equipment. This inefficient production mode has become a technical bottleneck restricting the large-scale production of the bearing industry. There is an urgent need to achieve a breakthrough in production efficiency through automated loading and unloading systems. To this end, a special machine for automatic loading and unloading of roller rounded corners is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Reference Figure 1 - Figure 9This utility model provides an embodiment of an automatic loading and unloading machine for roller rounding corners, including a fixed bracket 1. The fixed bracket 1 is the basic support part of the entire equipment, mainly playing the role of bearing and stabilizing.

[0039] The loading and unloading assembly includes a robot mounting base 14, which is fixedly connected to the top of the profile frame 5 to provide stable connection and support. A vacuum adsorption device 15 is installed on the outer wall of the robot mounting base 14. A six-axis collaborative robot 16 is rotatably connected inside the robot mounting base 14. Through a high-precision motion control system, it can complete complex motion trajectories, ensuring workpiece positioning and transmission. A positioning sleeve 8 is fixedly connected to one side of the six-axis collaborative robot 16, and an extension arm 7 is fixedly connected to the outer wall of the positioning sleeve 8. The connection between the positioning sleeve 8 and the extension arm 7 ensures that the robot can adapt to workpieces of different sizes. A connecting block 6 is fixedly connected to one side of the extension arm 7. Multiple pipe joints 11 are fixedly connected to the top of the connecting block 6, and a... Multiple floating joints 12 are provided, each with a floating spring 9 fitted on its outer wall. The floating joints 12 and floating springs 9 provide flexible support, ensuring the stability of the workpiece during transportation. Vacuum nozzles 10 are fixedly connected to the bottom of each floating joint 12 for vacuum adsorption of the workpiece, ensuring the equipment can adapt to workpieces of different sizes. A tilting conveyor assembly is installed on the top of the profile frame 5. This assembly is used to tilt and convey the workpiece. The tilting conveyor assembly includes a fixed base 17 and a tilting cylinder 18, providing the necessary power for tilting the workpiece. The fixed base 17 is fixedly connected to the top of the profile frame 5, and the tilting cylinder 18 is fixedly connected to the top of the fixed base 17. A centering finger 19 is fixedly connected to the output end of the tilting cylinder 18. Used to clamp workpieces and prevent them from falling during rotation, the protective assembly includes an aluminum profile frame 13, which is fixedly connected to the top of the fixed bracket 1. A transparent plate 2 is fixedly connected inside the aluminum profile frame 13, providing good protection without obstructing the operator's view of the work. A protective door 3 is installed inside the aluminum profile frame 13, which can be opened or closed as needed to ensure operational safety. A control device 30 is installed on one side of the profile frame 5, allowing the operator to view the equipment status in real time, adjust processing parameters, and start or stop the equipment, ensuring efficient operation of the entire production line. A power assembly 21 is installed inside the profile frame 5, driven by a rodless cylinder to ensure the stability of the assembly's movement. The top of the profile frame 5 is fixedly connected to a guide rail slider 20, which provides stable guidance for other components. A carrier plate 22 is slidably connected to the top of the profile frame 5. The carrier plate 22 slides inside the guide rail slider 20 and can slide freely under the guidance of the guide rail slider 20, providing load-bearing function. A pressure block 23 is fixedly connected to the top of the carrier plate 22. A quick-change tray 25 is slidably connected inside the pressure block 23 for storing workpieces. Multiple zero-point positioning devices 24 are provided on the top of the carrier plate 22 for accurately positioning workpieces and ensuring that the workpieces do not shift during processing. The zero-point positioning devices 24 all slide inside the quick-change tray 25. A support leg frame 26 is fixedly connected to the top of the profile frame 5, and a belt conveyor 27 is fixedly connected to the top of the support leg frame 26.The conveyor belt 27 is used to transport finished workpieces out of the equipment for easy collection by operators. A full-load detector 28 is installed inside the conveyor belt 27 to monitor the material status inside the equipment in real time, ensuring that workpieces are loaded or unloaded at the appropriate time.
[0040] Specifically, when faced with problems such as frequent product switching, low efficiency of manual loading and unloading, and poor product consistency in roller rounding processing, the operator first places the roller workpiece into the internal positioning hole of the quick-change tray 25. Stable positioning ensures accurate placement of the workpiece. Next, the operator selects the corresponding product program via the control device 30. The system automatically performs subsequent operations according to the selected program. Once the program is confirmed, the power unit 21 transports the quick-change tray 25 into the automation unit, ensuring the workpiece is smoothly conveyed along the predetermined trajectory. Subsequently, the six-axis collaborative robot 16 uses two vacuum nozzles 10 for precise gripping. Through the suction force of the vacuum nozzles 10, the component can flexibly adapt to and firmly grip workpieces of different sizes and shapes, effectively solving the problem of size differences between different workpieces. The vacuum nozzles 10 adsorb and stably move the workpiece inside the quick-change tray 25, accurately placing it on the designated machine tool for initial processing. After one side is processed, the drive... Vacuum nozzle 10 removes the incompletely processed workpiece and places it inside centering finger 19. Centering finger 19 precisely clamps the workpiece to ensure that it does not shift position during subsequent operations. Tilting cylinder 18 pushes the workpiece to rotate. After rotation, connecting block 6 and vacuum nozzle 10 work together to remove the workpiece again and place it in the processing area for secondary processing. Secondary processing is mainly used to round the corners of the workpiece to ensure that it reaches the required final shape and precision. After processing, connecting block 6 drives vacuum nozzle 10 to remove the processed workpiece and send it to the surface of conveyor belt 27 for further processing. At this time, full material detector 28 monitors the status of conveyor belt 27 and promptly reminds the staff to remove the workpiece when conveyor belt 27 reaches full material status. Transparent plate 2 provides efficient protection for the internal equipment and facilitates real-time observation of the equipment's operating status by the staff, ensuring the safety and smoothness of operation.
[0041] Working Principle: When using this automatic loading and unloading machine, the operator places the roller workpiece into the positioning hole inside the quick-change tray 25, and then selects the corresponding product program through the control device 30. After selection, the power unit 21 transports the quick-change tray 25 into the automation unit. Then, the six-axis collaborative robot 16 drives the two vacuum nozzles 10 to move. The vacuum nozzles 10 ensure that the equipment can adapt to the gripping of workpieces of different sizes. The vacuum nozzles 10 adsorb and pick up the workpiece inside the quick-change tray 25 and place it into the designated processing machine tool for processing. After processing on one side, the connecting block 6 drives the vacuum nozzles 10 again to pick up the workpiece. The incompletely processed workpiece is removed and placed inside the centering finger 19, which clamps it. The workpiece is then rotated by the flipping cylinder 18. After rotation, the workpiece is removed again and placed in the processing area for secondary processing through the cooperation of the connecting block 6 and the vacuum nozzle 10, so that the workpiece completes the rounding operation. After complete processing, the workpiece is removed again by the vacuum nozzle 10 driven by the connecting block 6 and placed on the surface of the conveyor belt 27. When the full material detector 28 detects that the material is full, it reminds the staff to remove the workpiece. At the same time, the transparent plate 2 can effectively protect the internal equipment and facilitate the user to observe the inside at any time.
