[0003] When machining the ball cage drive shaft, it needs to be processed using a gear rolling device. In the existing technology, the ball cage drive shaft is clamped into the placement frame by a robot arm, and the ball cage drive shaft is pushed into the gear rolling mechanism for processing by a cylinder. The ball cage drive shaft is positioned by the cooperation of the cylinder and the placement frame. The positioning accuracy is controlled by the robot arm, which cannot effectively ensure that the ball cage drive shaft is in the center position. Moreover, when machining ball cage drive shafts of different sizes, the clamping position of the robot arm needs to be adjusted. The adjustment requires high technical skills from the operator and is relatively complex. Therefore, we propose a gear rolling device for ball cage drive shafts. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a gear-rolling device for a ball cage drive shaft, which solves the problem that positioning the ball cage drive shaft by cooperating with a cylinder and a placement frame, relying on a robotic arm to control its positioning accuracy, cannot effectively ensure that the ball cage drive shaft is in the center position.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] This application provides a gear-rolling device for a ball cage drive shaft, which solves the problem that positioning the ball cage drive shaft by cooperating with a cylinder 31 and a placement frame, relying on a robotic arm to control its positioning accuracy, cannot effectively ensure that the ball cage drive shaft is in the center position. Instead, it achieves this by pushing the ball cage drive shaft into contact with the positioning unit 5, at which point the positioning unit 5 positions the ball cage drive shaft to the center position. By changing different positioning units 5, ball cage drive shafts of different sizes can be positioned without adjusting the position of the robotic arm. The ball cage drive shaft then pushes the positioning unit 5 to move, causing the positioning unit 5 to move the moving frame 42 accordingly. The moving frame 42 then slides along the guide rod 43, moving towards the fixed frame 41. The ball cage drive shaft is then inserted into the fixed frame 41, so that the processed end of the ball cage drive shaft is inserted into the gear-rolling mechanism, and the ball cage drive shaft is processed under the action of the gear-rolling device.
[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0025] This utility model discloses a gear-rolling device for a ball cage drive shaft.
[0026] According to the appendix Figure 1-3 As shown, the device includes a connecting frame 1, with mounting brackets on both sides. The connecting frame 1 is mounted to the gear-rolling device via the mounting brackets. A transmission rail 2 is provided on the connecting frame 1, and a traveling mechanism 3 is connected to the transmission rail 2. A cylinder 31 is mounted on the traveling mechanism 3, and an arc-shaped contact seat 32 is provided at the output end of the cylinder 31. A connecting unit 4 is provided on the connecting frame 1, and the connecting unit 4 includes:
[0027] A fixing frame 41 is mounted on the connecting frame 1, and the fixing frame 41 is correspondingly mounted on the tooth rolling mechanism;
[0028] A movable frame 42 is provided corresponding to a fixed frame 41, and a positioning unit 5 is installed on the outer wall of the movable frame 42.
[0029] Several guide rods 43 are fixedly connected to the outer wall of the fixed frame 41, and the movable frame 42 is slidably connected to the outer peripheral wall of the guide rods 43.
[0030] By pushing the ball cage drive shaft into contact with the positioning unit 5, the positioning unit 5 positions the ball cage drive shaft to the center position. By changing different positioning units 5, ball cage drive shafts of different sizes can be positioned without adjusting the position of the robot arm. At this time, the ball cage drive shaft pushes the positioning unit 5 to move, causing the positioning unit 5 to drive the moving frame 42 to move accordingly. At this time, the moving frame 42 slides along the guide rod 43, causing the moving frame 42 to move towards the fixed frame 41. At this time, the ball cage drive shaft is inserted into the fixed frame 41, so that the processing end of the ball cage drive shaft is inserted into the gear rolling mechanism. Under the action of the gear rolling equipment, the ball cage drive shaft is processed.
[0031] A guide frame 11 is provided on the outer wall of the connecting frame 1.
[0032] The ball cage drive shaft is pushed in the opposite direction by the movable frame 42, causing the ball cage drive shaft to fall onto the connecting frame 1, and the guide frame 11 can be used to conveniently store the ball cage drive shaft.
[0033] The arc-shaped contact seat 32 is set to connect unit 4 and positioning unit 5.
[0034] The cylinder 31 drives the arc-shaped contact seat 32 to move, so that the arc-shaped contact seat 32 pushes the ball cage drive shaft to be inserted into the positioning unit 5. At the same time, the arc-shaped contact seat 32 is set in an arc shape, and works with the positioning unit 5 to position the ball cage drive shaft. This allows for the positioning of ball cage drive shafts of different sizes, thereby improving the machining accuracy of the ball cage drive shaft.
[0035] A spring 44 is sleeved on the outer peripheral wall of the guide rod 43, and the two ends of the spring 44 are fixedly connected to the fixed frame 41 and the movable frame 42 respectively.
[0036] When the ball cage drive shaft is inserted into the positioning unit 5, the moving frame 42 is moved by pushing the positioning unit 5. At this time, the moving frame 42 slides along the guide rod 43 until the ball cage drive shaft passes through the fixed frame 41 and is in the tooth rolling mechanism. The ball cage drive shaft is processed by the tooth rolling mechanism in the tooth rolling equipment. The tooth rolling equipment is an existing mature equipment. This application will not describe the tooth rolling forming here.
[0037] After processing is completed, the arc-shaped contact seat 32 is moved backward until it is separated from the ball cage drive shaft. At this time, under the rebound of the spring 44, the moving frame 42 and the positioning unit 5 are pushed to move in the opposite direction, so that the ball cage drive shaft falls onto the connecting frame 1 and is collected along the guide frame 11.
[0038] The positioning unit 5 includes a positioning seat 51, and mounting blocks 53 are fixedly connected to both the upper and lower ends of the positioning seat 51. The mounting blocks 53 are installed to the movable frame 42 by bolts.
[0039] The positioning seat 51 has a positioning groove 52, which is arc-shaped.
[0040] When the arc-shaped contact seat 32 pushes the ball cage drive shaft into the positioning unit 5, the ball cage drive shaft contacts the positioning groove 52. With the combined action of the positioning groove 52 and the arc-shaped contact seat 32, the ball cage drive shaft is centered. By removing the bolts between the mounting block 53 and the moving frame 42, the positioning seat 51 can be disassembled, and different positioning grooves 52 can be replaced to position ball cage drive shafts of different sizes, improving machining accuracy.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
