Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular relates to a feeding device for a ball cage retainer. Background Technology

[0002] The ball cage retainer is an important component in a ball cage constant velocity universal joint. The ball cage retainer is usually designed with multiple windows to hold the steel balls, and the end face diameters at both ends of the ball cage retainer are different. Therefore, the loading of the ball cage retainer before milling usually involves issues such as the clamping angle of the robot and the reversal of the front and back sides.

[0003] For example, Chinese patent application number (2023102994311) discloses a carrier tray for ball cage loading and processing, which solves the problems of reversed front and back and internal impurities in the ball cage cage during loading and processing in the prior art. However, it cannot adjust the angle of the ball cage cage. Due to the influence of multiple windows on the ball cage cage, the direct clamping makes the contact surface shape between the robot and the ball cage cage not uniform. This can easily affect the stability of clamping when the robot clamps the ball cage cage and feeds it into the milling machine. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a ball cage cage feeding device that allows for angle adjustment during ball cage cage feeding, ensuring a uniform contact surface between the ball cage cage and the robotic arm, thereby guaranteeing stable clamping of the ball cage cage by the robotic arm.

[0005] In view of this, the present invention provides a feeding device for a ball cage retainer, comprising:

[0006] Conveyor belt mechanism for conveying ball cage cages one by one;

[0007] The frame is installed at the end of the conveyor belt mechanism;

[0008] The loading platform is installed on the frame and is set in a position corresponding to the output ball cage retainer of the conveyor belt mechanism, and is used to receive the ball cage retainer;

[0009] A limiting mechanism is installed on the side of the loading platform and is used to limit the ball cage retainer on the loading platform;

[0010] The transfer mechanism is installed on the side of the loading platform and is located on the opposite side of the limiting mechanism, and is used to clamp the ball cage retainer;

[0011] The detection mechanism is installed on the side of the loading platform and is located on the opposite side of the conveyor belt mechanism. It is used to detect the angle of the ball cage cage according to the window on the ball cage cage and provide feedback.

[0012] A robotic arm is used to grip the ball cage retainer with the adjusted angle from the transfer mechanism and transport it to the machining table of the milling machine;

[0013] The transfer mechanism adjusts the angle of the ball cage based on feedback from the testing agency.

[0014] In the above technical solution, the loading platform further includes:

[0015] The first baffle is installed on the loading platform and is used to limit the ball cage retainer in the direction in which the ball cage retainer enters the loading platform from the conveyor belt mechanism.

[0016] The second baffle is installed on the loading platform and is perpendicular to the first baffle. It is used in conjunction with the limiting mechanism to limit the ball cage retainer in a direction perpendicular to the direction along which the ball cage retainer enters the loading platform from the conveyor belt mechanism.

[0017] In the above technical solution, the limiting mechanism further includes:

[0018] The first mounting bracket is installed on the loading platform;

[0019] A cylinder is mounted on a first mounting bracket and has a push plate at its output end, which is used to push the ball cage retainer against the second baffle.

[0020] In the above technical solution, the transit agency further includes:

[0021] The second mounting frame is installed above the loading platform via a lifting device;

[0022] The first indexer is mounted on the second mounting bracket, and its output end is set corresponding to the loading platform;

[0023] A three-jaw cylinder is installed at the output end of the first indexer and is used to hold the ball cage retainer on the loading platform.

[0024] In the above technical solution, the transit agency further includes:

[0025] The second mounting frame is installed above the loading platform via a lifting device;

[0026] The first indexer is mounted on the second mounting bracket, and its output end is set corresponding to the loading platform;

[0027] A three-jaw cylinder is installed at the output end of the first indexer and is used to hold the ball cage retainer on the loading platform.

[0028] In the above technical solution, further:

[0029] The lifting device includes a lead screw drive assembly and a drive motor, and is located on the opposite side of the limiting mechanism.

[0030] In the above technical solution, the testing organization further includes:

[0031] The third mounting bracket is installed on the side of the loading platform and is located on the opposite side of the conveyor belt mechanism;

[0032] Infrared sensors are mounted on the third mounting bracket, and there are two of them, arranged side by side in the horizontal direction;

[0033] The distance between the two infrared sensors must be equal to the width of the connection between two adjacent windows on the ball cage cage.

[0034] In the above technical solution, further:

[0035] The third mounting bracket has an adjustment slot along the horizontal direction, which is used for the adjustable setting of the two infrared sensors along the horizontal direction on the third mounting bracket.

[0036] The beneficial effects of this utility model are as follows:

[0037] 1. The ball cage retainer is received by the loading platform, then the limiting mechanism limits it, and then the transfer mechanism clamps the ball cage retainer. The angle of the ball cage retainer is adjusted according to the feedback of the detection mechanism, so as to make the contact surface shape of the robot arm uniform when clamping the ball cage retainer. This allows the robot arm to make corresponding deformation according to the contact surface, thereby effectively improving the clamping and conveying stability of the ball cage retainer by the robot arm.

[0038] 2. By using a three-jaw cylinder to clamp the ball cage cage, the ball cage cage can be centered and clamped, ensuring the accuracy of the detection and adjustment of the ball cage cage angle;

[0039] 3. The angle of the ball cage cage is adjusted before loading by using cylinders, indexers, screw drive components, drive motors and infrared sensors. This is a combination of common devices, with a simple structure and low manufacturing cost.

[0040] 4. By making the two infrared sensors on the side of the detection mechanism adjustable, the angle of different ball cage cages can be easily adjusted, effectively improving applicability. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0045] Example 1:

[0046] This embodiment provides a feeding device for a ball cage retainer 2, including:

[0047] Conveyor belt mechanism 1, used to convey ball cage retainers 2 one by one;

[0048] Frame 3 is installed at the end of conveyor belt mechanism 1;

[0049] The loading platform 4 is installed on the frame 3 and is set in a position corresponding to the output ball cage retainer 2 of the conveyor belt mechanism 1, and is used to receive the ball cage retainer 2;

[0050] The limiting mechanism 5 is installed on the side of the loading platform 4 and is used to limit the ball cage retainer 2 on the loading platform 4;

[0051] The transfer mechanism 6 is installed on the side of the loading platform 4 and is located on the opposite side of the limiting mechanism 5, and is used to clamp the ball cage retainer 2.

[0052] The detection mechanism 7 is installed on the side of the loading platform 4 and is located on the opposite side of the conveyor belt mechanism 1. It is used to detect the angle of the ball cage 2 according to the window on the ball cage 2 and provide feedback.

[0053] A robotic arm is used to grip the ball cage retainer 2 after the angle has been adjusted from the transfer mechanism 6 and transport it to the machining table of the milling machine;

[0054] Among them, the transfer mechanism 6 adjusts the angle of the ball cage based on the feedback from the testing mechanism 7;

[0055] Meanwhile, the specific structures of the conveyor belt mechanism 1 and the robotic arm mechanism are existing technologies and will not be described in detail here.

[0056] As can be seen in this embodiment, the ball cage retainer 2 is received by the loading platform 4, then limited by the limiting mechanism 5, then clamped by the transfer mechanism 6, and the angle of the ball cage retainer 2 is adjusted according to the feedback of the detection mechanism 7. This makes it easier for the robot to uniformly shape the contact surface when clamping the ball cage retainer 2, so that the robot can make a corresponding deformation according to the contact surface, thereby effectively improving the clamping and conveying stability of the ball cage retainer 2 by the robot.

[0057] Furthermore, by adjusting the angle of the ball cage cage 2 as described above, the structure of the robot arm can be simplified. That is, the robot arm only needs simple clamping and movement to complete the fully automatic feeding of the ball cage cage 2.

[0058] Example 2:

[0059] This embodiment provides a feeding device for a ball cage retainer 2. In addition to the technical solutions of the above embodiments, it also has the following technical features: the feeding platform 4 includes:

[0060] The first baffle 40 is installed on the loading platform 4 and is used to limit the ball cage retainer 2 in the direction from the conveyor belt mechanism 1 to the loading platform 4.

[0061] The second baffle 41 is installed on the loading platform 4 and is set perpendicular to the first baffle 40. It is used to cooperate with the limiting mechanism 5 to limit the ball cage retainer 2 in a direction perpendicular to the direction along which the ball cage retainer 2 enters the loading platform 4 from the conveyor belt mechanism 1.

[0062] As can be seen from this embodiment, the first baffle 40 ensures the positional accuracy of the ball cage retainer 2 as it enters the loading platform 4 from the conveyor belt mechanism 1, while the second baffle 41 facilitates ensuring the positional accuracy of the ball cage retainer 2 after it is limited by the limiting mechanism 5, thereby ensuring that the ball cage retainer 2 is clamped by the transfer mechanism 6, and thus ensuring the angle adjustment and loading of the ball cage retainer 2.

[0063] Example 3:

[0064] This embodiment provides a feeding device for a ball cage retainer 2. In addition to the technical solutions of the above embodiments, it also has the following technical features: the limiting mechanism 5 includes:

[0065] The first mounting bracket 50 is installed on the loading platform 4;

[0066] Cylinder 51 is mounted on the first mounting bracket 50, and has a push plate 52 at its output end, which is used to push the ball cage retainer 2 against the second baffle 41.

[0067] The specific structure of cylinder 51 is existing technology and will not be described in detail here.

[0068] As can be seen from this embodiment, the cylinder 51 pushes the push plate 52, which in turn pushes the ball cage retainer 2 against the second baffle 41. When the cylinder 51 retracts, it is convenient for the transfer mechanism 6 to clamp the ball cage. The structure is simple and the manufacturing cost is low.

[0069] The first mounting bracket 50 improves the ease and stability of cylinder 51 installation;

[0070] Furthermore, after the cylinder 51 pushes the push plate 52 to limit the ball cage retainer 2, it can retract.

[0071] Example 4:

[0072] This embodiment provides a feeding device for a ball cage retainer 2. In addition to the technical solutions of the above embodiments, it also has the following technical features: the transfer mechanism 6 includes:

[0075] The three-jaw cylinder 62 is installed at the output end of the first indexer 61 and is used to hold the ball cage retainer 2 on the loading table 4.

[0076] Among them, the first indexer 61 is a miniature indexer, and its specific structure, along with that of the three-jaw cylinder 62, is based on existing mature technologies, which will not be elaborated here.

[0077] As can be seen from this embodiment, by using a three-jaw cylinder 62 to clamp the ball cage retainer 2, the ball cage retainer 2 can be centered and clamped, ensuring the accuracy of the detection and adjustment of the angle of the ball cage retainer 2. Furthermore, the lifting device 8 can drive the output end of the three-jaw cylinder 62 to extend into the ball cage retainer 2 after it is limited by the limiting mechanism 5. After clamping, it is lifted to be level with the detection mechanism 7. Then, the first indexer 61 adjusts the ball cage retainer 2 after receiving feedback from the detection mechanism 7, ensuring that the angle of the ball cage retainer 2 is uniform, thereby improving the stability of the gripper.

[0078] Example 5:

[0079] This embodiment provides a feeding device for a ball cage retainer 2. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the transfer mechanism 6 further includes:

[0081] The second mounting bracket 60 is mounted on the output end of the second indexer 63, and the second indexer 63 is used to drive the second mounting bracket 60 to rotate in the vertical plane.

[0082] Meanwhile, the second indexer 63 is a micro indexer, and its specific structure is existing technology, which will not be described in detail here.

[0083] As can be seen from this embodiment, by installing the second indexer 63 at the output end of the lifting device 8 and installing the second mounting bracket 60 at the output end of the second indexer 63, the ball cage retainer 2 can be adjusted from a horizontal state to a vertical state after the angle of the ball cage retainer 2 is adjusted, which further facilitates the gripping and grasping of the robot and improves the feeding efficiency.

[0084] Example 6:

[0085] This embodiment provides a feeding device for a ball cage retainer 2, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0086] The lifting device 8 includes a lead screw transmission assembly 80 and a drive motor 81, and is located on the opposite side of the limiting mechanism 5;

[0087] The specific structures of the lead screw drive assembly 80 and the drive motor 81 are existing technologies and will not be described in detail here.

[0088] As can be seen from this embodiment, by setting the lifting device 8 as a screw drive assembly 80 and a drive motor 81, the stability of the lifting of the second mounting bracket 60 can be improved, and the structure is simple and the manufacturing cost is low.

[0091] The third mounting bracket 70 is installed on the side of the loading platform 4 and is located on the opposite side of the conveyor belt mechanism 1;

[0092] Infrared sensors 71 are mounted on the third mounting bracket 70, and two of them are arranged side by side along the horizontal direction;

[0093] The distance between the two infrared sensors 71 must be equal to the width of the connection between two adjacent windows on the ball cage retainer 2.

[0094] Meanwhile, the specific structure of the infrared sensor 71 is a mature existing technology, and will not be described in detail here.

[0095] As can be seen from this embodiment, by using two infrared sensors 71 arranged side by side in the horizontal direction, and setting the distance between the two infrared sensors 71 to be equal to the width of the connection between two adjacent windows on the ball cage retainer 2, when both infrared sensors 71 detect the workpiece, it means that the connection between two adjacent windows on the ball cage retainer 2 is facing the third mounting bracket 70. Thus, by adjusting the ball cage retainer 2 so that the connection is facing the third mounting bracket 70 each time, it can be ensured that the contact surface between the ball cage retainer 2 and the robot arm is uniform when the robot arm clamps the ball cage retainer 2, thereby effectively ensuring the stability of clamping.
