Description

Technical Field

[0001] This utility model relates to the field of bearing ring manufacturing technology, specifically to a forging and bottom-cutting tool for small tapered bearing rings. Background Technology

[0002] In the production of small tapered roller bearing rings, forging and undercutting is a critical process that requires specialized tooling to ensure machining accuracy and efficiency. Traditional forging and undercutting tooling for small tapered roller bearing rings is mostly a single-station design. When changing materials, it is necessary to stop the current station, release the limit on the already machined ring, remove it, and then put in the new ring to be machined and limit it again. This process wastes a lot of time and seriously affects production efficiency. Summary of the Invention

[0003] In view of the problems existing in the forging and bottom cutting tooling of small tapered bearing rings, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a tooling for forging and cutting the bottom of small tapered bearing rings, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A forging and bottom-cutting fixture for small tapered bearing rings includes a base shell and two fixed plates. The two fixed plates are fixedly disposed on both sides of the upper surface of the base shell. A strip-shaped opening is formed in the middle of the upper surface of the base shell. Two movable plates are slidably disposed inside the strip-shaped opening. A U-shaped plate is slidably disposed inside the base shell. A through groove is formed in the side wall of the U-shaped plate. A horizontal plate is slidably disposed in the inner wall of the through groove. Both ends of the horizontal plate are fixedly connected to the inner wall of the base shell. A sliding groove is formed in the upper surface of the U-shaped plate. An adjustment mechanism for moving the two movable plates is disposed inside the sliding groove. A transmission mechanism for moving the U-shaped plate is disposed inside the base shell.

[0006] Preferably, the adjusting mechanism includes a bidirectional lead screw, which is horizontally rotatably disposed inside the slide groove, and the lower ends of the two movable plates are respectively threadedly connected to one end of the bidirectional lead screw.

[0007] Preferably, the transmission mechanism includes a turntable and a movable frame. A rotating rod is rotatably mounted on the rear inner wall of the bottom shell. The turntable is fixedly sleeved on the rod wall. A round pin is eccentrically mounted on the front side of the turntable. A movable frame is fixedly mounted in the middle of the lower surface of the U-shaped plate. The front end of the round pin passes through the movable frame. A motor is fixedly mounted on the rear side of the bottom shell. The output end of the motor is fixedly connected to the rear end of the rotating rod.

[0008] Preferably, a slide bar is arranged parallel to the lower side of the bidirectional lead screw, both ends of the slide bar are fixedly connected to the inner wall of the slide groove, and the lower end of the movable plate is movably sleeved with the slide bar.

[0009] Preferably, the rod wall of the round pin, on the side of the movable frame away from the turntable, is fixedly fitted with an anti-detachment ring.

[0010] Preferably, the bottom shell has an opening on its rear side.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a motor to drive a turntable to rotate, which causes the round pin to rotate around the rotating rod as an axis. During this rotation, the round pin slides within the movable frame, causing the round pin to push the movable frame to move, thereby moving the U-shaped plate. The U-shaped plate drives the two movable plates to move synchronously, so that one movable plate moves closer to the corresponding fixed plate while the other movable plate moves away from the corresponding fixed plate. This allows for simultaneous work limit on one side and release of the limit on the other side, reducing the time wasted on material changes and improving production efficiency.

[0012] 2. In this utility model, by rotating the bidirectional lead screw, the bidirectional lead screw drives the two movable plates to move in opposite directions, which can adjust the distance between the two movable plates and the corresponding fixed plates, thus facilitating the limiting of bearing rings of different diameters.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a tooling for forging and cutting the bottom of a small tapered bearing ring.

[0020] Reference Figure 1-3 A forging and bottom-cutting fixture for small tapered bearing rings includes a base shell 1 and two fixing plates 2. The two fixing plates 2 are fixedly disposed on both sides of the upper surface of the base shell 1. A strip-shaped opening is provided in the middle of the upper surface of the base shell 1. Two movable plates 5 are slidably disposed inside the strip-shaped opening. A U-shaped plate 4 is slidably disposed inside the base shell 1. A through groove is provided on the side wall of the U-shaped plate 4. A horizontal plate 3 is slidably disposed on the inner wall of the through groove. Both ends of the horizontal plate 3 are fixedly connected to the inner wall of the base shell 1. A sliding groove is provided on the upper surface of the U-shaped plate 4. An adjustment mechanism for moving the two movable plates 5 is provided inside the sliding groove. A transmission mechanism for moving the U-shaped plate 4 is provided inside the base shell 1.

[0021] Reference Figure 1-3 The adjustment mechanism includes a bidirectional lead screw 6, which is horizontally rotatably mounted inside the slide groove. The lower ends of two movable plates 5 are threadedly connected to one end of the bidirectional lead screw 6. A slide rod 7 is arranged parallel to the lower side of the bidirectional lead screw 6. Both ends of the slide rod 7 are fixedly connected to the inner wall of the slide groove. The lower end of the movable plate 5 is movably connected to the slide rod 7, so that the movable plate 5 can slide stably. An opening is provided on the rear side of the bottom shell 1 to facilitate reaching into the bottom shell 1 for operation.

[0022] Reference Figure 1-3 The transmission mechanism includes a turntable 9 and a movable frame 10. A rotating rod 8 is rotatably mounted on the inner rear wall of the bottom shell 1. The turntable 9 is fixedly sleeved on the rod wall of the rotating rod 8. A round pin 11 is eccentrically mounted on the front side of the turntable 9. A movable frame 10 is fixedly mounted in the middle of the lower surface of the U-shaped plate 4. The front end of the round pin 11 passes through the movable frame 10. A motor 12 is fixedly mounted on the rear side of the bottom shell 1. The output end of the motor 12 is fixedly connected to the rear end of the rotating rod 8. An anti-detachment ring is fixedly sleeved on the rod wall of the round pin 11 on the side of the movable frame 10 away from the turntable 9 to prevent the round pin 11 from slipping out of the movable frame 10 as much as possible.

[0023] In this utility model, during use, the limiting distance is adjusted according to the diameter of the small tapered bearing ring to be processed: the bidirectional lead screw 6 is rotated through the opening on the rear side of the bottom shell 1. Since the lower ends of the two movable plates 5 are respectively threaded to the two ends of the bidirectional lead screw 6, and the movable plates 5 are movably sleeved with the slide rod 7 and cannot rotate, when the bidirectional lead screw 6 rotates, it drives the two movable plates 5 to slide in the opposite direction along the slide rod 7 until the distance between the movable plates 5 and the corresponding fixed plates 2 is adapted to the bearing ring size, thus completing the limiting width adjustment. When the motor 12 is started, the motor 12 drives the rotating rod 8 to rotate. The turntable 9 on the rotating rod 8 rotates synchronously. The round pin 11, which is eccentrically set on the front side of the turntable 9, makes a circular motion around the rotating rod 8 as the axis. The round pin 11 slides in the movable frame 10 and pushes the movable frame 10 to move laterally, thereby driving the U-shaped plate 4 to slide horizontally along the horizontal plate 3 (the horizontal plate 3 plays a guiding and limiting role on the U-shaped plate 4 to ensure smooth movement). When the U-shaped plate 4 moves to one side, the left movable plate 5 gradually moves away from the left fixed plate 2. The fixed plate 2 and the movable plate 5 press against the inner walls of both sides of the bearing ring, completing the limitation of the bearing ring, and the bottom cutting can be performed. At the same time, the right movable plate 5 moves closer to the right fixed plate 2, releasing the limitation of the processed ring. The operator can remove the finished product and put in the new ring to be processed. When the U-shaped plate 4 moves in the opposite direction, the right movable plate 5 and the right fixed plate 2 cooperate to press against the inner wall of the new ring, and the left side releases the limitation to change the material. Through this dual-station alternating operation mode, processing and material changing are carried out simultaneously, greatly reducing downtime. The anti-slip ring on the rod wall of the round pin 11 can effectively prevent it from slipping out of the movable frame 10, ensuring transmission stability. This device realizes automatic switching between two workstations through mechanical transmission. With the adjustable limit structure, it can not only adapt to the processing requirements of bearing rings of different specifications, but also significantly improve production efficiency.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
