[0039] In order to make the purpose, technical solutions and advantages of this application more clear, the application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are part of the embodiments of this application, rather than all of the embodiments, and are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

In addition, the terms "first", "second", "superior", "inferior", "primary", "secondary", etc. are used for descriptive purposes only and can be simply used to more clearly distinguish different components, but cannot be understood as indicating or implying relative importance.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, integral connections, mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application in specific contexts.

[0042] See also Figures 1-4 , a bearing raceway forming device for a bearing outer ring, comprising a machine tool bed 1, and a support platform 2 fixedly connected to the machine tool bed 1 (other parts of the machine tool are omitted);

[0043] The front end of the main shaft above the support platform 2 is provided with a fixture 4 for clamping the outer ring of the bearing, which can be driven to rotate by the first driving member; (the fixture 4 is installed on the main shaft which is driven by the motor, the belt connected to the motor drive end, and the belt that rotates synchronously with the belt)

[0044] It also includes: a forming component 6 located on the support platform 2, the forming component 6 includes a rotatable extrusion wheel 62, and the extrusion wheel 62 can extend into the outer ring of the bearing and abut against the raceway on the outer ring of the bearing under the drive of the position adjustment mechanism 61. After the extrusion wheel 62 abuts against the raceway on the outer ring of the bearing, the clamp 4 drives the outer ring of the bearing to rotate so that the extrusion wheel 62 extrude and strengthen the raceway on the outer ring of the bearing.

[0045] The clamp is used to clamp the outer ring of the bearing and drive the outer ring of the bearing to rotate together. The extrusion wheel 62 can be extended into the outer ring of the bearing under the drive of the position adjustment mechanism and abut against the raceway on the outer ring of the bearing (located on the inner wall, and the balls of the final product bearing are located in the raceway). After the extrusion wheel 62 abuts against the raceway on the outer ring of the bearing, the clamp 4 drives the outer ring of the bearing to rotate so that the extrusion wheel 62 extrude and strengthen the raceway on the outer ring of the bearing. Since the extrusion wheel 62 can be adjusted according to the position of the outer ring of the bearing, it can not only facilitate the processing of the inner raceway of the outer ring of the bearing, but also improve the adaptability to bearings of different sizes.

[0046] Furthermore, the position adjustment mechanism 61 includes an X-axis slide rail or X-axis slide groove 611 (that is, it can be a slide rail or a slide platform. If it is a slide rail, there is a corresponding slide groove on the slider. If it is a slide groove, there is a corresponding slide rail on the slider.) arranged on the X-axis slide rail or X-axis slide groove 611, an X-axis slider 612 is arranged on the X-axis slider 612, a Y-axis slide rail or Y-axis slide groove 613 is arranged on the X-axis slider 612, a Y-axis slider 614 is arranged on the Y-axis slide rail or Y-axis slide groove 613, a first driving member 615 drives the X-axis slider 612 to move on the X-axis slide rail or X-axis slide groove 611, a second driving member 616 drives the Y-axis slider 614 to move on the Y-axis slide rail or Y-axis slide groove 613, and the extrusion wheel 62 is arranged on the Y-axis slider 614.

[0047] The position adjustment mechanism 61 enables the extrusion wheel 62 to move along the X-axis and Y-axis directions on the horizontal plane. The movement in the X-axis direction allows the extrusion wheel 62 to extend into the outer ring of the bearing from the side perpendicular to the outer ring of the bearing, and the movement in the Y direction allows the extrusion wheel 62 to rest against the raceway of the outer ring of the bearing.

[0048] In this embodiment of the bearing raceway forming device for a bearing outer ring, the first and second drive members 615 and 616 are both motors. These drive members 615 and 616 respectively drive the X-axis slider 612 and the Y-axis slider 614 via a ball screw transmission pair. The motors and ball screw transmission pair enable relatively precise displacement control.

[0049] Furthermore, in the bearing raceway forming device for the bearing outer ring of this embodiment, the fixture is mounted on a connecting flange 40. The fixture 4 is a three-jaw chuck, but other multi-jaw chucks are also possible. The fixture 4 includes a body 41 and three jaws 42. The jaws 42 can move toward or away from a center point to abut and secure the bearing outer ring from the outside. The jaws 42 are typically hydraulically driven. The three jaws 42 form a centering structure that ensures the bearing outer ring is secured and the center point is fixed.

[0050] In the bearing raceway forming device for the bearing outer ring of this embodiment, the extrusion wheel 62 rotates freely.

[0051] Of course, if necessary, the extrusion wheel 62 can also be set on a driving member to drive the rotation. In this case, the clamp 4 does not need to rotate.

[0052] The bearing raceway forming device for a bearing outer ring used in this embodiment also includes a cooling and lubricating assembly for spraying cooling and lubricating fluid onto the bearing outer ring on the fixture 4. The cooling and lubricating assembly is similar to that on conventional machine tools. Spraying cooling and / or lubricating fluid onto the bearing outer ring can not only reduce the temperature, but also reduce the impact of dust on the processing environment.

[0053] Working principle: The outer ring of the bearing is placed on the fixture 4 manually or by a robot. The fixture 4 is actuated to fix the outer ring of the bearing. Then, the extrusion wheel 62 is moved along the Y-axis direction to align with the hollow part of the outer ring of the bearing (generally speaking, the initial position of the extrusion wheel 62 is already aligned with the hollow part of the outer ring of the bearing, so there is no need to adjust the Y-axis position). The X-axis position of the extrusion wheel 62 is adjusted to allow the extrusion wheel 62 to enter the outer ring of the bearing. The Y-axis position of the extrusion wheel 62 is then adjusted to allow the extrusion wheel 62 to abut the raceway on the inner wall of the outer ring of the bearing. The extrusion wheel 62 is driven to rotate and process the raceway of the outer ring of the bearing. After processing is completed, the extrusion wheel 62 is removed from the outer ring of the bearing (the removal method is the opposite of the entry method and is not detailed here). The outer ring of the bearing is then removed from the fixture 4 manually or by a robot, and another outer ring of the bearing can be processed.

[0054] The above descriptions are merely some embodiments of the present application and are intended to illustrate the technical solution of the present application, not to limit it. It should be understood that those skilled in the art may make improvements or substitutions based on the above description without departing from the inventive concept of the present application, and all such improvements and substitutions shall fall within the scope of protection of the appended claims of the present application. In such cases, all details may be replaced with equivalent elements, and the materials, shapes, and dimensions may be arbitrary.
