[0002] Bearing ring forgings have high hardness after heat treatment, making hard turning a crucial step in their precision machining. However, existing hard turning machine tools have some shortcomings. On the one hand, traditional machine tools are mostly single-spindle structures, resulting in low machining efficiency and difficulty in meeting the needs of mass production. On the other hand, the installation and adjustment of cutting tools are not flexible enough. For bearing ring forgings of different specifications and shapes, frequent tool changes or adjustments to tool positions are required, which is not only cumbersome but also affects machining accuracy and efficiency. Furthermore, the accumulation of metal chips during machining can easily cause secondary scratches. Therefore, we propose a hard turning machine tool for bearing ring forgings.

On the other hand, the installation and adjustment of tools are not flexible enough. For bearing ring forgings of different specifications and shapes, it is necessary to frequently change tools or adjust tool positions, which is not only cumbersome to operate, but also affects the processing accuracy and efficiency. In addition, the accumulation of metal chips during the processing can easily cause secondary scratches.

[0022] This utility model discloses a machine tool for hard turning bearing ring forgings. Dust collection frames 20 are slidably mounted on the surfaces of two support columns 9 on one side. A dust collector 21 is fixedly installed on one side of each of the two dust collection frames 20.

[0024] This utility model discloses a machine tool for hard turning bearing ring forgings. The machine tool base 1 has a collection frame 26 that slides inside.

[0025] In use, the bearing ring forging is placed on two clamping bases 3. The controller 27 starts the first telescopic rod 6, and the moving end of the first telescopic rod 6 pushes the arc-shaped clamping plate 7 closer to the forging until the forging is clamped. At this time, the pressure sensor 8 in the arc-shaped clamping plate 7 will detect the clamping force in real time and transmit the signal to the controller 27. When the clamping force reaches the appropriate range, the controller 27 controls the first telescopic rod 6 to stop moving, completing the clamping of the forging. According to the processing requirements, the controller 27 starts the second motor 24, which drives the first screw 12 to rotate, causing the fixing block 14 located on the surface of the first screw 12 and the slide bar 13 to move horizontally, thereby driving the mounting frame 15 and the tool chuck 19 below to move to the appropriate lateral position. Then, the third motor 25 is started, which drives the second screw 16 to rotate, causing the mounting block 17 to move within the mounting frame 15, thereby adjusting the longitudinal position of the tool chuck 19. Finally, the controller 27 starts the third motor 25, which drives the second screw 16 to rotate, causing the mounting block 17 to move within the mounting frame 15, thereby adjusting the longitudinal position of the tool chuck 19. The controller 27 controls the extension and retraction of the hydraulic cylinder 18 to adjust the vertical position of the cutting tool, ensuring it reaches the precise position required for machining. The controller 27 starts the first motor 4, which drives the clamping base 3 and the forging to rotate. Simultaneously, the cutting tool performs hard turning on the rotating forging. During machining, the controller 27 starts the second telescopic rod 23, which pushes the dust collection frame 20 to a suitable height. At the same time, the dust collector 21 is activated, sucking in the metal debris generated during machining through the dust collection frame 20 and then conveying it through the telescopic tube 22 to the collection frame 26 inside the machine tool base 1. After machining is completed, the controller 27 stops all components from working. The first telescopic rod 6 drives the arc-shaped clamping plate 7 to release the forging, allowing the machined forging to be removed. Simultaneously, the cutting tool resets under the drive of the motors, and the dust collection frame 20 lowers and resets under the action of the second telescopic rod 23. The entire machining process is completed. The collection frame 26 can be removed to clean up the debris for the next machining operation.
