[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Example 1: An industrial robot arm assembly, such as Figure 1 - Figure 5As shown, the device includes a support arm 1, a support cylinder 2 for rotating transmission support, a limiting rotating ring 3 sleeved on the outside of the support arm 1, and a limiting fixing ring 4 sleeved on the outside of the support cylinder 2. The end of the support arm 1 near the limiting fixing ring 4 is fixedly connected to the outer rotating shaft. The support cylinder 2 is inserted into the outer rotating shaft. The limiting rotating ring 3 is fixedly installed on the outside of the support arm 1, and the limiting fixing ring 4 is fixedly installed on the outside of the support cylinder 2. Limiting rotating plates 5 and limiting fixing plates 6 are respectively provided on adjacent sides of the limiting rotating ring 3 and the limiting fixing ring 4. Several limiting rotating plates 5 are inserted into the limiting rotating ring 3. The limiting fixing plates 6 are used to limit the rotation of the limiting rotating plates 5. The limiting rotating ring 3 rotates synchronously with the support arm 1 under the support of the drive source. The limiting fixing ring 4 and the support cylinder 2 are in a fixed state.
[0027] When the support arm 1 is driven by the drive source through the outer rotating shaft, the rotation of the support arm 1 causes the limiting rotating ring 3 to rotate simultaneously, and the limiting rotating plate 5 to rotate synchronously with the limiting rotating ring 3. Since the limiting fixing ring 4 and the support cylinder 2 are in a fixed state, the limiting fixing plate 6 is also in a fixed state. When the limiting rotating ring 3 continues to rotate, the limiting rotating plate 5 gradually contacts the limiting fixing plate 6. Thus, under the fixed limit of the limiting fixing plate 6 itself, the rotation of the limiting rotating plate 5, the limiting rotating ring 3, and the support arm 1 is limited, thus restricting the rotation stroke of the support arm 1. Furthermore, by adjusting the two limiting rotating plates 5 in different positions and using them in combination, the support arm 1 can rotate to different strokes, giving the device a manual adjustment mode for the rotation stroke. At the same time, the device has a forced limiting effect, effectively preventing overload during rotation and improving the adjustability and reliability of the device during rotation.
[0028] like Figure 1 - Figure 5 As shown, at least two rotation guide grooves 7 are provided on the surface of the limiting rotating plate 5 near the limiting fixed plate 6, and a rotating guide plate 8 installed on the surface of the limiting rotating plate 5 is provided between the two rotation guide grooves 7.
[0029] The limiting and fixing ring 4 has an annular limiting groove 9 on one side of the limiting rotating ring 3. Limiting guide rails 10 are installed on the surface of the limiting and fixing ring 4 on opposite sides of the annular limiting groove 9. The rotating guide plate 8 is inserted into the annular limiting groove 9 and slidably disposed inside it. The limiting guide rail 10 is inserted into the rotating guide groove 7 and extends into it.
[0030] When one or two of the limiting rotating plates 5 are selected for travel limit, the limiting rotating plate 5 is pushed toward the limiting fixing ring 4, so that the rotating guide plate 8 on one side is inserted into the annular limiting groove 9, and the rotating guide grooves 7 on both sides are simultaneously inserted into the limiting guide rail 10, providing combined limit for the limiting rotating plate 5, improving the accuracy of its angle and position during rotation, and providing limit assistance for the rotation of the support arm 1.
[0031] like Figure 1 - Figure 5 As shown, at least two protruding limiting plates 11 are installed on the side surface of the limiting fixing plate 6, and a guide groove 12 is provided between the two protruding limiting plates 11 on the surface of the limiting fixing plate 6.
[0032] At least two annular grooves 13 are provided on the side surface of the limiting rotating ring 3. The annular grooves 13 are connected to the rotating guide grooves 7 on the limiting rotating plate 5 in the contracted state. The protruding limiting plate 11 is slidably disposed inside the annular grooves 13 and the rotating guide grooves 7 in the contracted state. The rotating guide plate 8 in the contracted state is slidably disposed inside the guide groove 12.
[0033] While the device rotates, the protruding limiting plate 11 rotates inside the annular rail groove 13 and the retracted rotating guide groove 7. The multiple rotating guide plates 8 in the retracted state are inserted and rotated inside the guide groove 12, ensuring that they are mutually limited and stable, while not affecting the normal rotation of the limiting rotating plate 5 outside the limiting area.
[0034] Example 2: An industrial robot arm assembly, such as Figure 1 - Figure 5 As shown, a slender adjusting bolt 14 is rotatably connected to one end of the limiting rotating plate 5 away from the rotating guide groove 7. A short and thick adjusting bolt 15 is installed at one end of the slender adjusting bolt 14. Several multi-specification adjusting holes 16 are provided through the limiting rotating ring 3, and the slender adjusting bolt 14 and the short and thick adjusting bolt 15 are threadedly connected to the inner wall of the multi-specification adjusting holes 16.
[0035] The internal structure of the multi-specification adjustment hole 16 is adapted to the short and thick adjustment bolt 15, the slender adjustment bolt 14, and the limiting rotating plate 5 respectively, and the angle between each adjacent two sides of the multi-specification adjustment hole 16 is 15° with the center of the circular cross section of the limiting rotating ring 3 as the reference point.
[0036] Based on the threaded connection between the multi-specification adjustment hole 16 and the slender adjustment bolt 14 and the short and thick adjustment bolt 15, the position of the limiting rotating plate 5 can be easily moved and adjusted by rotating the short and thick adjustment bolt 15. At the same time, under the action of thread tightening, the limiting rotating plate 5, the slender adjustment bolt 14, and the short and thick adjustment bolt 15 are kept in a stable connection state during adjustment, which also facilitates adjustment and stable tightening when storing them, thus improving the convenience of use.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
