Technical Field

[0001] This utility model relates to the field of bearing guide ring machining technology, and in particular to a composite turning fixture for efficient machining of multiple bearing guide rings. Background Technology

[0002] The bearing guide ring usually refers to the bearing cage, which is an important component of the bearing. Its main function is to guide and separate the rolling elements. There are usually three types of guiding methods for the bearing cage: rolling element guiding, inner ring guiding, and outer ring guiding.

[0003] In existing technologies, there are multiple processes in the manufacturing of bearing guide rings, including turning. Turning can precisely machine the key dimensions of the bearing guide ring raw material to the design tolerance range, thereby transforming the raw material into a material that meets the application requirements of the bearing system.

[0004] However, during the machining of bearing guide rings, fixtures are required. When fixing the guide ring with the fixture, there may be defects in the fixture that prevent it from being clamped from the inner wall of the guide ring after clamping from the outer wall. This makes it impossible to flexibly switch the clamped surface of the guide ring according to machining needs, and this method cannot meet different machining requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a composite turning fixture for efficient machining of multiple bearing guide rings.

[0014] 1.

When the turntable rotates clockwise, the inner rod drives the two horizontal plates to move towards each other synchronously, and the two clamping rods will move towards each other in the same way until the two clamping rods are tightly fitted with the outer wall of the bearing guide ring. Then the motor rotates in the opposite direction, driving the turntable to move in the opposite direction, and the inner rod moves in the opposite direction along the arc-shaped groove.

[0025] Example 1

[0026] like Figures 1-5As shown, this utility model provides a technical solution: a composite turning fixture for efficient machining of multiple bearing guide rings, including a clamping mechanism 1, an auxiliary mechanism 2 provided on the inner wall of one end of the clamping mechanism 1, the clamping mechanism 1 including a fixed platform 11, a limiting groove 114 formed on the top side of the fixed platform 11, a clamping rod 13 provided on the inner surface of the limiting groove 114, the inner surface of the limiting groove 114 being slidably connected to the outer side of the clamping rod 13, and a horizontal plate 12 provided at the bottom end of the clamping rod 13. The bottom end of the clamping rod 13 is fixedly connected to the top side of the horizontal plate 12. An inner rod 16 is provided on the inner wall of the middle end of the horizontal plate 12. The upper and lower ends of the inner rod 16 are rotatably connected to the inner wall of the middle end of the horizontal plate 12. A turntable 14 is provided on the inner wall of the middle end of the horizontal plate 12. One side of the turntable 14 is in contact with the inner wall of the middle end of the horizontal plate 12. An arc-shaped groove 15 is opened on the inner wall of the turntable 14. The inner surface of the arc-shaped groove 15 is rotatably in contact with the outer side of the inner rod 16. A guide rail 17 is provided on the inner wall of one end of the horizontal plate 12. One end of the horizontal plate 12 is slidably connected to the outer side of the guide rod. One end of the guide rod is fixedly connected to the bottom side of one end of the fixed platform 11. A roller 18 is provided on the inner wall of one end of the horizontal plate 12. The connecting end of the roller 18 is fixedly connected to the inner wall of one end of the horizontal plate 12. The outer side of the roller 18 is slidably connected to the top side of the guide rail 17. One side of the fixed platform 11 is fixedly connected to the top of the base 19. A scraper 110 is provided on the inner surface of the base 19. The inner surface of the base 19 is connected to the scraper 110. One end of 110 is slidably connected, and a pull rod 111 is provided on one side of the scraper 110. One side of the scraper 110 is fixedly connected to one end of the pull rod 111. A motor 112 is provided at the center of the bottom side of the turntable 14. The center of the bottom side of the turntable 14 is fixedly connected to the output end of the motor 112. A base support 113 is provided on the outside of the motor 112. The outside of the motor 112 is fixedly connected to the middle of the base support 113. The top of the base support 113 is fixedly connected to the bottom side of the fixed plate.

[0027] In this embodiment, the composite turning fixture for high-efficiency machining of multiple bearing guide rings is used by having five limiting grooves 114 on the top side of the fixed table 11. Each of the five limiting grooves 114 has a clamping rod 13 on its inner surface. There are five sets of clamping rods 13, with two in each set. The bottom ends of the two clamping rods 13 are fixed to the top side of the horizontal plate 12. The horizontal plate 12 has two clamping rods. The inner wall of the middle end of each of the two horizontal plates 12 is designed with an inner rod 16. The arc surface of the inner rod 16 is located within an arc-shaped groove 15. The arc-shaped groove 15 has a certain inclination and is formed on the turntable 14. Furthermore, one side of the arc-shaped groove 15... The inner rod 16 is located near the edge of the turntable 14. Therefore, by starting the motor 112, the turntable 14 and inner rod 16 will undergo radial displacement along the arc-shaped groove 15. When the turntable 14 rotates clockwise, the inner rod 16 moves towards the center of the turntable 14 under the thrust of the groove wall, causing the two connected horizontal plates 12 to move towards each other synchronously. During the movement of the horizontal plates 12, the two sets of clamping rods 13 fixed on their top sides will slide smoothly within the limiting groove 114 of the fixed platform 11, gradually reducing the distance between each set of clamping rods 13 until the two clamping rods 13 are tightly fitted against the outer wall of the bearing guide ring, achieving synchronous clamping and positioning of five workpieces. After the workpieces are clamped, the motor 112 can maintain the turntable 14 in a stationary state through a braking device, ensuring stable clamping force of the fixture on the workpiece during processing and avoiding the impact of workpiece loosening on processing accuracy.

[0028] Since arc-shaped recesses are provided on both the left and right sides of the clamping rod 13, this method can not only clamp the outer wall of the bearing guide ring, but also clamp and fix the inner wall of the bearing, thereby meeting different processing requirements and enabling quick adjustment according to actual conditions.

[0029] By installing a guide plate on the bottom side of one end of the fixed plate, the outer side of the guide plate penetrates the inner wall of one end of the horizontal plate 12, and a roller 18 is designed on the inner wall of one end of the horizontal plate 12. The roller 18 contacts the guide plate, so that when the fixed plate slides, the horizontal plate 12 slides along the guide constraint provided by the guide plate, ensuring that the fixed plate always slides along the preset trajectory and avoiding deviation. At the same time, the rolling contact between the roller 18 on the inner wall of the horizontal plate 12 and the surface of the guide plate can convert the sliding friction between the two into rolling friction, which greatly reduces the frictional resistance during the movement and makes the operation smoother.

[0030] A base 19 is installed below the fixed plate. The base 19 is concave, and a scraper 110 is designed on the inner surface of the base 19. A pull rod 111 is fixed to one side of the scraper 110. During the processing, some waste is generated. Some of the waste will fall into the base 19 automatically under the action of gravity. After the processing is completed, by applying a pulling force to one side to the pull rod 111, the scraper 110 is driven to slide in a straight line along the inner surface of the base 19. During the sliding process, the waste accumulated in the base 19 can be completely scraped off. The scraped waste will be concentrated and pushed to the opening on one side of the base 19 for subsequent collection.

[0031] Example 2

[0032] like Figures 1-5 As shown, the auxiliary mechanism 2 includes a receiving plate 21. A positioning rod 22 is provided at one end of the receiving plate 21. One end of the receiving plate 21 is fixedly connected to one end of the positioning rod 22. A base 19 is provided on the outside of the positioning rod 22. The outside of the positioning rod 22 is fitted and connected to the inner wall of one end of the base 19. One end of the base 19 is in contact with one end of the receiving plate 21.

[0033] In this embodiment, a receiving plate 21 is installed at one end of the base 19. When the waste is located at the opening at one end of the base 19, the receiving plate 21 is flush with the inner surface of the base 19. By using a tool, the waste at the opening is placed on the receiving plate 21, and the receiving plate 21 collects the waste. A positioning rod 22 is fixed at one end of the receiving plate 21. The positioning rod 22 is located on the inner wall of one end of the base 19, which pulls the receiving plate 21 to one side, causing the positioning rod 22 to come out of the base 19, so that the waste on the receiving plate 21 can be further processed.

[0034] Working principle:

[0035] like Figures 1-5 As shown, by providing arc-shaped recesses on both the left and right sides of the support rod, starting the motor 112 causes the turntable 14 and inner rod 16 to move radially along the arc-shaped groove 15. When the turntable 14 rotates clockwise, the inner rod 16 drives the two horizontal plates 12 to move towards each other synchronously, and the two clamping rods 13 move towards each other in the same way until the two clamping rods 13 are tightly fitted with the outer wall of the bearing guide ring, thus achieving synchronous clamping and positioning of five workpieces. Then, the motor 112 rotates in the opposite direction, causing the turntable 14 to move in the opposite direction, the inner rod 16 to move in the opposite direction along the arc-shaped groove 15, and the horizontal plates 12 to move the support rods away from each other. This method can clamp from the inner wall of the bearing guide ring to meet different processing requirements. After the workpiece is clamped, the motor 112 can keep the turntable 14 stationary through the braking device to ensure that the clamping force of the fixture on the workpiece is stable during the processing and to avoid affecting the processing accuracy due to the loosening of the workpiece.

[0036] During the processing, some waste is generated. Some of the waste will fall into the base 19 automatically under the action of gravity. After the processing is completed, by applying a pulling force to one side to the pull rod 111, the scraper 110 is driven to slide in a straight line along the inner surface of the base 19. During the sliding process, the waste accumulated in the base 19 can be completely scraped off. The scraped waste will be concentrated and pushed to one side opening of the base 19 for subsequent processing.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
