Description

Technical Field

[0001] The utility model relates to the technical field of ball cage processing, in particular to a ball cage turning mechanism. Background Art

[0002] The ball cage, also known as the "constant velocity joint", is an important component in the car transmission system. Its function is to transfer the engine power from the transmission to the drive wheel to drive the car at high speed. There are many types of constant velocity joints used in cars, among which the most commonly used are the ball cage type constant velocity joint and the tripod type constant velocity joint, which are mainly composed of sliding sleeves, three-way shafts, transmission shafts, star sleeves, cages, bell housings and other main components. Since the constant velocity joint transmits heavy driving torque, is subject to heavy loads, has high transmission accuracy, is in great demand, and is also a safety component, its main parts are all made of precision forgings. At present, in the production and processing of ball cages, it is necessary to feed the ball cage to the robot arm to grab it and put it into the ball cage grinder to grind the working surface of the ball cage window and other processing. The inventor of the present application has discovered through research that in the process of grabbing the ball cage to the ball cage grinder by a robotic arm, the ball cage may be upside down. In this case, the ball cage needs to be turned over before processing. Currently, the upside-down ball cage is mainly turned over manually, and then the robotic arm is waited for to re-grab it. Therefore, this method requires someone to watch all the time to complete the flipping, which results in high labor costs and restricts the construction progress of the ball cage processing automated production line. This technical problem needs to be urgently resolved. Utility Model Content

[0003] In view of the existing problem that in the process of grabbing the ball cage to the ball cage grinder by a mechanical arm, the ball cage may be turned upside down. At this time, it is necessary to turn over the upside-down ball cage manually. This method has high labor costs and restricts the construction progress of the ball cage processing automated production line. The utility model provides a ball cage turning mechanism.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A ball cage flipping mechanism comprises a supporting platform, a driving motor and a bearing support are fixed on the table surface of the supporting platform, a bearing is fixedly inlaid on the bearing support, a transmission shaft is fixed in the center hole of the bearing, one end of the transmission shaft is fixedly connected to the output shaft of the driving motor, and the other end of the transmission shaft is fixedly connected to a supporting plate, the length direction of the support plate is horizontally inclined relative to the central axis of the transmission shaft to form a predetermined angle, a three-jaw chuck is fixed to the outer end surface of the support plate, and the clamping surfaces of the inner ends of the three jaws of the three-jaw chuck facing the center of the chuck are arc-shaped surfaces that match the outer wall of the ball cage.

[0006] Compared with the prior art, when the ball cage flipping mechanism provided by the utility model is used, the upside-down ball cage is first grabbed by a mechanical arm and placed between the inner ends of the three claws of the three-jaw chuck, and then the three claws move toward the center of the three-jaw chuck to clamp the ball cage, and then the driving motor is started. After the motor output shaft drives the support plate to rotate 180 degrees through the transmission shaft, the three claws move back to the center of the three-jaw chuck to release the ball cage, and the ball cage is placed on the support platform surface. After that, the mechanical arm grabs the flipped ball cage again for processing. This method does not require manual flipping operations, which not only saves labor costs, but also has high work efficiency, and is very beneficial to the construction of an automated production line for ball cage processing.

[0007] Furthermore, a rubber pad is laid on the support platform, and the projection position of the rubber pad and the three-jaw chuck on the support platform surface is mirror-imaged relative to the central axis of the transmission shaft.

[0008] Furthermore, the length direction of the support plate is inclined in the horizontal direction relative to the central axis of the transmission shaft to form a predetermined angle of 30 to 60 degrees.

The purpose of such design is to separate the positions of the ball cage before and after turning over to avoid the support plate 5 blocking the robotic arm and making it inconvenient for the robotic arm to grasp. A three-jaw chuck 6 is fixed to the outer end surface of the support plate 5. The three-jaw chuck 6 includes a chuck body and three claws 7 arranged around the chuck body and movable radially along the chuck body. The three-jaw chuck 6 can be driven by a motor to achieve clamping or loosening. Therefore, the three-jaw chuck 6 and the drive motor 2 can be connected to an existing external controller for control. The specific structure and working principle of the three-jaw chuck 6 are mature existing technologies and are not described in detail here. The clamping surface 71 at the inner end of the three claws 7 facing the center of the chuck in the three-jaw chuck 6 is an arc surface that matches the outer wall of the ball cage, thereby better clamping the ball cage.

[0017] Compared with the prior art, when the ball cage flipping mechanism provided by the utility model is used, the upside-down ball cage is first grabbed by a mechanical arm and placed between the inner ends of the three claws of the three-jaw chuck, and then the three claws move toward the center of the three-jaw chuck to clamp the ball cage, and then the driving motor is started. After the motor output shaft drives the support plate to rotate 180 degrees through the transmission shaft, the three claws move back to the center of the three-jaw chuck to release the ball cage, and the ball cage is placed on the support platform surface. After that, the mechanical arm grabs the flipped ball cage again for processing. This method does not require manual flipping operations, which not only saves labor costs, but also has high work efficiency, and is very beneficial to the construction of an automated production line for ball cage processing.

[0018] As a specific example, please refer to Figure 1 As shown, a rubber pad 8 is also laid on the support platform 1, and the projection position of the rubber pad 8 and the three-jaw chuck 6 on the surface of the support platform 1 is mirrored relative to the central axis of the transmission shaft 4, that is, the setting position of the rubber pad 8 corresponds to the three-jaw chuck 6 after the support plate 5 is rotated 180 degrees, thereby preventing the ball cage from sliding after being placed on the support platform surface, facilitating accurate grasping by the robot arm.

[0019] As a specific example, please refer to Figure 1 As shown, the predetermined angle α formed by the length direction of the support plate 5 relative to the central axis of the transmission shaft 4 is 30-60° in the horizontal direction, thereby allowing the front and rear positions of the ball cage to be more spaced apart, making it easier for the robot arm to grasp accurately.
