Description

Technical Field

[0001] This application relates to the field of bearing technology, and in particular to a bearing ring forging raceway expansion device. Background Technology

[0002] Bearing rings are components installed between the inner and outer rings of a bearing to reduce friction and wear between the bearing and external parts. They are usually made of metallic materials, such as steel or aluminum alloys, and have high strength and wear resistance. Bearing rings require the use of a bearing ring forging raceway rolling and expanding device during processing. This device is a type of equipment used to process bearing rings by rolling and expanding them through raceways.

[0003] In the field of raceway machining for bearing ring forgings, existing equipment often uses fixed-specification rolling and expanding structures, making it difficult to adapt to the raceway requirements of bearing rings of different sizes or depths, thus limiting production flexibility. In existing technologies, the design of auxiliary support structures (such as positioning rollers) is often unreasonable, making it difficult to maintain the axial and radial stability of the bearing rings during the rolling and expanding process, easily leading to misalignment or vibration. Summary of the Invention

[0004] The purpose of this application is to provide a bearing ring forging raceway expansion device to solve the above problems. It uses raceway rolling rings of different specifications to adapt to bearing ring raceways of different sizes or depths. Furthermore, the auxiliary roller is provided with a trapezoidal auxiliary groove, which can maintain the axial and radial stability of the bearing ring and prevent it from easily causing displacement or vibration.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] A bearing ring forging raceway expansion device includes: a housing, a bearing seat, a first motor, a rotating shaft, a support roller, raceway rolling rings, a telescopic cylinder, a pressure frame, and a pressure roller. A material inlet is provided at the front of the housing. The bearing seat is fixedly connected to the rear of the housing. The rotating shaft passes through the bearing seat and is rotatably connected to it. The first motor is fixedly installed at the rear of the bearing seat, and its output shaft is fixedly connected to the first end of the rotating shaft. The support roller is coaxially fixedly connected to the second end of the rotating shaft. The telescopic cylinder is located at the top of the housing, with its output end facing downwards. The pressure frame is fixedly connected to the output end of the telescopic cylinder. The pressure roller is rotatably connected to the pressure frame, which is positioned above the support roller. Multiple sets of raceway rolling rings are provided on the outer walls of the support roller and the pressure roller, with adjacent raceway rolling rings having different specifications.

[0007] Furthermore, it also includes a positioning roller bracket and an auxiliary roller. The positioning roller bracket consists of two sets, which are fixedly installed on a drive assembly that can drive them to move synchronously in the opposite direction. The auxiliary roller is rotatably connected to the positioning roller bracket, and the outer wall of the auxiliary roller is provided with an auxiliary groove of the same amount as the raceway rolling ring.

[0008] Furthermore, the drive assembly includes a slide table, a second motor, a bidirectional screw, and a slider. The slide table is fixedly connected to the housing, the bidirectional screw is rotatably connected to the slide table, the second motor is fixedly installed at the end of the slide table, and the output shaft of the second motor is fixedly connected to the bidirectional screw. There are two sets of sliders, which are respectively screwed to the two sections of the bidirectional screw with opposite rotation directions. The two sets of positioning roller brackets are fixedly installed on the sliders one by one.

[0009] Furthermore, the raceway rings are distributed along the axial direction of the idler roller, and the cross-section of the raceway rings increases sequentially.

[0010] Furthermore, the axial directions of the shaft, idler roller, and auxiliary roller are all in the same direction.

[0011] Furthermore, the cross-section of the auxiliary groove is trapezoidal.

[0012] Compared with the prior art, the idler roller and pressure roller of this application use raceway rings of different specifications to adapt to bearing ring raceways of different sizes or depths, and the auxiliary roller is provided with trapezoidal auxiliary grooves, which can maintain the axial and radial stability of the bearing rings and are not prone to displacement or vibration.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figure 1-3 As shown, a bearing ring forging raceway expansion device includes: a housing 1, a bearing seat 3, a first motor 4, a rotating shaft 5, a roller 6, raceway rolling rings 7, a telescopic cylinder 8, a pressure frame 9, and a pressure roller 10. A material inlet 2 is provided at the front of the housing 1. The bearing seat 3 is fixedly connected to the rear of the housing 1. The rotating shaft 5 passes through the bearing seat 3 and is rotatably connected to the bearing seat 3. The first motor 4 is fixedly installed at the rear of the bearing seat 3, and its output shaft is fixedly connected to the first end of the rotating shaft 5. The roller 6 is coaxially fixedly connected to the second end of the rotating shaft 5. The telescopic cylinder 8 is located at the top of the housing 1, with its output end facing downwards. The pressure frame 9 is fixedly connected to the output end of the telescopic cylinder 8. The pressure roller 10 is rotatably connected to the pressure frame 9, and the pressure frame 9 is positioned above the roller 6. Multiple sets of raceway rolling rings 7 are provided on the outer walls of the roller 6 and the pressure roller 10, with adjacent raceway rolling rings 7 having different specifications.

[0022] Specifically, the housing 1 is used to support various components, the material inlet 2 facilitates the loading and unloading of bearing rings, and the pressure roller 10 is driven to descend by the telescopic cylinder 8, which can apply pressure to the bearing rings to expand them. At the same time, the raceway grinding rings 7 of different specifications can adapt to bearing ring raceways of different depths. The bearing seat 3 can enhance the rotational stability of the shaft 5 and can also bear the pressure applied by the telescopic cylinder 8. The roller 6 and the corresponding raceway grinding rings 7 on the outer wall of the pressure roller 10 have the same specifications.

[0023] Furthermore, it also includes a positioning roller bracket 15 and an auxiliary roller 16. The positioning roller bracket 15 consists of two sets, which are fixedly installed on a drive assembly that can drive them to move synchronously in the opposite direction. The auxiliary roller 16 is rotatably connected to the positioning roller bracket 15, and the outer wall of the auxiliary roller 16 is provided with an auxiliary groove 17 that is equal in number to the raceway rolling ring 7.

[0024] Specifically, the two sets of positioning roller brackets 15 clamp the bearing ring from both sides simultaneously, which can maintain the stability of the bearing ring being driven to rotate. At the same time, the edge of the bearing ring can be located inside the auxiliary groove 17 to further maintain stability and avoid shaking.

[0025] Furthermore, the drive assembly includes a slide table 11, a second motor 12, a bidirectional screw 13, and a slider 14. The slide table 11 is fixedly connected to the housing 1, the bidirectional screw 13 is rotatably connected to the slide table 11, the second motor 12 is fixedly installed at the end of the slide table 11, and the output shaft of the second motor 12 is fixedly connected to the bidirectional screw 13. There are two sets of sliders 14, which are respectively screwed to the two sections of the bidirectional screw 13 with opposite directions of rotation. Two sets of positioning roller brackets 15 are fixedly installed on the sliders 14 one by one.

[0026] Specifically, the oppositely spiraled threads enable the two sliders 14 to move synchronously in opposite directions, thus allowing adjustment of the gap between the auxiliary rollers 16 to clamp or release the bearing rings.

[0027] Furthermore, the raceway rings 7 are distributed along the axial direction of the idler roller 6, and the cross-section of the raceway rings 7 increases sequentially to accommodate the raceway of the bearing rings.

[0028] Furthermore, the axial directions of the rotating shaft 5, the idler roller 6, and the auxiliary roller 16 are all in the same direction.

[0029] Furthermore, the cross-section of the auxiliary groove 17 is trapezoidal to accommodate bearing rings of different widths, so that both sides of the bearing ring are inside the auxiliary groove 17 for fit, thereby maintaining stability during the rotation of the bearing ring.

[0030] In the above structure, the bearing is fitted onto the raceway grinding ring 7. Different sizes of raceway grinding ring 7 can adapt to different raceways. The telescopic cylinder 8 is activated to extend and drive the pressure roller 10 to descend, so that the pressure roller 10 contacts the bearing ring. Then, the second motor 12 is activated to drive the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the two sliders 14 to move synchronously in opposite directions, and then the two auxiliary rollers 16 approach to clamp the bearing ring. Then, the first motor 4 is activated to drive the rotating shaft 5 to rotate, so that the raceway grinding ring 7 on the support roller 6 rotates and the bearing ring is rolled and expanded. After the rolling and expansion is completed, the bearing ring can be released by reversing the above steps. Repeated operation can continuously roll and expand the raceway of the bearing ring.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
