Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing robot technology, and in particular to a robot for high-efficiency and precision machining of low-pressure aluminum alloy wheel hubs. Background Technology

[0002] Aluminum alloy wheels are made of aluminum alloy and are typically manufactured through casting or forging processes. Aluminum alloys have advantages such as low density, high strength, and corrosion resistance, effectively reducing vehicle weight compared to traditional steel wheels. Their structure generally includes a rim and spokes. The rim mounts the tire, while the spokes connect the rim to the vehicle's hub axle, providing support and transmitting force. During the processing of aluminum alloy wheels, robotic arms are needed to handle the loading and unloading of the wheels.

[0003] Existing robotic arms for high-efficiency precision machining of low-pressure aluminum alloy wheels often employ a single-claw structure, which makes it inconvenient to adjust the spacing between the claws. This makes it difficult for the robotic arm to grip and pick up wheels of different sizes, thus affecting the efficiency of aluminum alloy wheel machining. Utility Model Content

[0016] Furthermore, the cooperation between the guide plate and the guide groove can improve the stability of the sliding of the movable block and further improve the stability of the adjustment and movement of the gripper.

[0017] Furthermore, by activating the main body of the robotic arm, the upper and lower grippers can be flipped to grip and pick up the aluminum alloy wheel hub.

[0018] By rotating the bolts, the bolts can be moved out of the threaded holes and the limiting position of the mating block can be released, which facilitates the disassembly and replacement of the limiting post.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides a robotic arm for high-efficiency precision machining of low-pressure aluminum alloy wheel hubs, comprising a robotic arm body 1.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an adjustment mechanism 2 is installed at the output end of the robot body 1. The adjustment mechanism 2 has a sliding groove 3 inside, and a guide groove 4 is formed on the inner wall of the sliding groove 3. The adjustment mechanism 2 includes a housing 21 movably installed at the output end of the robot body 1. A drive motor 22 is installed inside the housing 21. The output shaft of the drive motor 22 is fixedly connected to a rotating rod 23 via a coupling. One end of the rotating rod 23 is fixedly connected to a first bevel gear 24. A second bevel gear 25 is movably connected to the outer wall of the first bevel gear 24. A bidirectional lead screw 26 is fixedly connected to the inner wall of the second bevel gear 25. A movable block 27 is movably connected to the outer wall of the rod 26. The movable block 27 has a threaded groove 28 inside. A guide plate 29 is fixedly connected to one side of the movable block 27. The first bevel gear 24 forms a rotating structure with the outer shell 21 through the rotating rod 23. The first bevel gear 24 is meshed with the second bevel gear 25. The second bevel gear 25 forms a rotating structure with the outer shell 21 through the double-acting screw 26. The double-acting screw 26 is threadedly connected to the movable block 27 through the threaded groove 28. The guide plate 29 forms a sliding structure with the outer shell 21 through the guide groove 4. The guide groove 4 is symmetrically arranged about the central axis of the outer shell 21.

[0029] By starting the drive motor 22, the rotating rod 23 can be rotated, causing the first bevel gear 24 to rotate. Since the first bevel gear 24 is meshed with the second bevel gear 25, the second bevel gear 25 can be rotated, driving the bidirectional lead screw 26 to rotate. Since the bidirectional lead screw 26 is threadedly connected to the movable block 27 through the threaded groove 28, the two movable blocks 27 can move towards or away from each other along the bidirectional lead screw 26, causing the guide plate 29 to slide along the guide groove 4. This allows the distance between the two grippers 51 to be adjusted. By starting the robot body 1, the upper and lower sets of grippers 51 can be flipped to grip and pick up the aluminum alloy wheel hub.

[0030] Reference Figure 1 , Figure 2 Figure 4 and Figure 5 As shown, an assembly mechanism 5 is fixedly connected to the outer wall of the guide plate 29. The assembly mechanism 5 includes a gripper 51 fixedly installed on the outer wall of the guide plate 29. A mating groove 52 is opened inside the gripper 51. A mating block 53 is installed inside the mating groove 52. A threaded hole 54 is opened inside the mating block 53. A limit post 55 is fixedly connected to the bottom of the mating block 53. A bolt 56 is movably connected inside the gripper 51. The gripper 51 is engaged with the mating block 53 through the mating groove 52. The gripper 51 is designed with an open hole. The bolt 56 is threadedly connected to the mating block 53 through the threaded hole 54. The bolt 56 is compatible with the threaded hole 54.

[0031] By rotating the bolt 56, since the bolt 56 is threadedly connected to the mating block 53 through the threaded hole 54, the bolt 56 can be moved out of the threaded hole 54 and the limiting position on the mating block 53 can be released. Pulling the limiting post 55 can move the mating block 53 out of the mating groove 52, thus disassembling the limiting post 55. Move the limiting post 55 of the required model so that the mating block 53 can be inserted into the mating groove 52. Then rotate the bolt 56 to limit the mating block 53 and install the limiting post 55 on the outer wall of the gripper 51.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
