[0002] Ball cages are essential components for the commutation joints in automotive differentials. High machining precision is required, requiring the rough-machined product to be transferred to a grinder for fine machining. In existing processes, the ball cage cannot be directly placed into position after being picked up by a robotic arm and placed on the grinder's machining axis. This can easily tilt, requiring manual alignment and installation. Otherwise, the workpiece can be damaged during automated machining, and manual alignment in the grinder also poses safety risks.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is described in detail in the following embodiments with reference to the accompanying drawings.

[0025] See Figures 1 to 6 As shown in , the material-retrieving device with a workpiece pushing structure provided in this embodiment is applied to a ball cage workpiece loading and unloading production line, which includes a storage device for storing ball cage workpieces, a grinder for processing ball cage workpieces, and a robotic arm for transferring ball cage workpieces between the storage device and the processing axis of the grinder; the material-retrieving device includes:

[0026] Connecting base 1, fixedly connected to the end of the robotic arm;

[0027] The rotating base 2 is rotatably mounted on the end of the connecting base 1 away from the robot arm, and the connecting base 1 has a driving member for causing the rotating base 2 to rotate circumferentially;

[0028] At least one pneumatic claw 3, the rear end of which is fixedly connected to the rotating base 2, and the front end of which constitutes a clamping claw 9 for clamping the ball cage workpiece, and each clamping claw 9 is also respectively installed with an elastic pushing member 4;

[0029] Moreover, when the jaws 9 clamp the workpiece, the free end of the elastic pushing member 4 contacts the workpiece and is in a compressed state. When the jaws 9 release the workpiece, the elastic pushing member 4 is released and pushes the workpiece to place the workpiece into the processing axis of the grinder or the storage device.

[0030] Based on the above technical solution, the material picking device includes a connecting seat 1, a rotating seat 2, a material picking air claw 3, and an elastic pushing member 4. The setting of the elastic pushing member 4 enables the elastic pushing member 4 to be released when the claw 9 releases the workpiece, and pushes the workpiece to prompt the workpiece to be placed in the processing shaft of the grinder or the storage device, ensuring that the ball cage workpiece is installed in place in the processing shaft, avoiding the workpiece being out of place or skewed, which causes the grinder to be unable to automatically process or damage the workpiece, thereby increasing the product yield.

[0031] In a preferred embodiment, a mounting plate 5 is mounted horizontally on each claw 9. The mounting plate 5 has two through-holes facing the claws 9, each of which is movably penetrated by a screw 6. The ends of the two screws 6 facing away from the mounting plate 5 are connected to a push plate 8. A spring 7 is also sleeved on the outer periphery of each screw 6. The ends of the spring 7 respectively abut against the mounting plate 5 and the push plate 8. The mounting plate 5, screw 6, push plate 8, and spring 7 together constitute an elastic push member 4. This makes the structure more stable and reliable. However, it is obvious that the elastic push member 4 can also be directly implemented by a spring 7 or other elastic member, and is not limited to this.

[0032] In a preferred embodiment, the driving component is a rotating cylinder or a stepping motor, both of which can achieve the purpose of rotating the rotating seat 2 relative to the connecting seat 1. Furthermore, the number of the material-picking claws 3 is two, and they are arranged at 90 degrees to each other in the side view direction. Furthermore, the projection of the rotating seat 2 in the side view direction is a right triangle as a whole, and the two material-picking claws 3 are respectively connected to the two right-angled sides. Furthermore, two air flow channels matching the two material-picking claws 3 are formed in the rotating seat 2, and the two air flow channels converge into a gas flow channel in the rotating seat 2, and an air flow inlet and outlet 10 connected to the gas flow channel is formed at one end of the rotating seat 2 where the connecting seat 1 is matched, so as to enable the two material-picking claws 3 to move synchronously. But obviously, the two material-picking claws 3 can also be designed to be controlled separately rather than to move synchronously. Furthermore, each mounting plate 5 is erected on the clamping claw 9 through two connecting rods 11 arranged on both sides.

[0033] In addition, combined Figure 5 and Figure 6 As shown in FIG, the robot arm 12 adopts a truss structure, which can stably clamp the workpiece through the material picking device and transfer it between the storage device 14 and the processing axis 15 of the grinder 13.

[0034] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
