[0002] A humanoid robot, also known as an anthropomorphic robot or a humanoid robot, is a robot with a human form and functions, equipped with anthropomorphic limbs, motion and operation skills, as well as perception, learning and cognitive abilities. Humanoid robots play an important role in many fields such as industrial production, service industries, medical and health, education and research, emergency rescue, home companionship, and display and entertainment.

[0003] When processing the leg housing of a humanoid robot, a corresponding processing jig is generally used to clamp the leg housing. The existing processing jigs for clamping the leg housing mainly use a pressure block and a screw to position the leg housing. Specifically, after placing the leg housing on the processing jig, the pressure block is pressed on the upper surface of the leg housing, and then the screw is used to fix the pressure block. In this way, when processing multiple parts on the same side of the leg housing, such as drilling and threading different parts on the inner side of the leg housing, it is necessary to loosen the screw, move the pressure block to avoid interference, press the pressure block on other parts of the leg housing, and then tighten the screw. Thus, the operation is cumbersome, resulting in low processing efficiency and a large amount of manual labor. Summary of the Utility Model

[0035] Please refer to Figures 1 to 7 , and now the fixture for machining the robot leg housing provided by the embodiment of the present application will be described. The fixture for machining the robot leg housing is used for clamping the leg housing 100 of the robot. The leg housing 100 of the robot is mainly a leg housing 100 imitating a robot, such as the leg housing 100 of a humanoid robot, etc.

[0036] Please refer to Figure 1 and Figure 4, a processing fixture for a robot leg housing, comprising: a workbench 10, a first positioning post 20, and a first pressing and fixing device 30. The workbench 10 has a processing area 11; the first positioning post 20 is arranged on the workbench 10 and is located within the processing area 11; the first pressing and fixing device 30 is arranged on the workbench 10; the number of the first pressing and fixing devices 30 is multiple, and the multiple first pressing and fixing devices 30 are spaced apart and distributed around the processing area 11. The first pressing and fixing device 30 includes a first pressing block 31 and a first rotating and pressing mechanism 32 connected to the first pressing block 31 and used to drive the first pressing block 31 to rotate and move up and down. The first pressing block 31 can extend horizontally above the processing area 11.

[0037] Please refer to Figures 1 to 4 , when clamping the robot leg housing 100 with the processing fixture for the robot leg housing according to the embodiment of the present application, place the leg housing 100 in the processing area 11, support the part of the leg housing 100 suspended relative to the workbench 10 by the first positioning post 20, and drive the first pressing block 31 to rotate and press down through the first rotating and pressing mechanism 32 of a part of the first pressing and fixing devices 30, so as to rotate the first pressing block 31 above the processing area 11 and press it on the leg housing 100, thereby realizing stably clamping the leg housing 100 on the workbench 10. During the processing of the leg housing 100, when it is necessary to avoid the first pressing block 31 of a part of the first pressing and fixing devices 30, drive the corresponding first pressing block 31 to rise and rotate through the first rotating and pressing mechanism 32 of this part of the first pressing and fixing devices 30, rotate the first pressing block 31 to the outside of the processing area 11, and then drive the corresponding first pressing block 31 to rotate and press down through the first rotating and pressing mechanism 32 of another part of the first pressing and fixing devices 30, rotate the first pressing block 31 above the processing area 11 and press it on the leg housing 100.

[0038] It should be noted that when it is not necessary for the first pressing and fixing device 30 to avoid the leg housing 100, the first pressing blocks 31 of all the first pressing and fixing devices 30 can also be pressed on the leg housing 100, which is beneficial to improving the positioning stability of the leg housing 100.

[0039] The processing fixture for the robot leg housing provided by the present application, compared with the prior art, by arranging a plurality of first pressing and fixing devices 30 spaced around the processing area 11, when a part of the first pressing and fixing devices 30 avoid the position of the leg housing 100 placed in the processing area 11, the leg housing 100 can be positioned by another part of the first pressing and fixing devices 30, and the first rotating and pressing mechanism 32 of the first pressing and fixing device 30 drives the first pressing block 31 to rotate and move up and down, so that the first pressing block 31 automatically presses on the leg housing 100 and automatically moves away from the leg housing 100, with high automation and convenient operation, which is beneficial to improving the processing efficiency and reducing the manual labor amount, and by the first positioning column 20 supporting the part of the leg housing 100 suspended relative to the workbench 10, it is beneficial to improve the clamping stability of the leg housing 100.

[0040] Optionally, the first positioning column 20 can be inserted into the positioning hole existing in the leg housing 100 itself to support the part of the leg housing 100 suspended relative to the workbench 10. Of course, the first positioning column 20 can also directly support on the lower surface of the part of the leg housing 100 suspended relative to the workbench 10.

[0041] Please refer to Figure 1 , in an embodiment of the present application, the number of the first positioning columns 20 is multiple, and the multiple first positioning columns 20 are spaced and distributed in the processing area 11. By arranging multiple first positioning columns 20 to support the part of the leg housing 100 suspended relative to the workbench 10, it is beneficial to improve the positioning stability of the leg housing 100.

[0042] In an embodiment of the present application, the first rotating and pressing mechanism 32 is a rotating and pressing cylinder, and the rotating and pressing cylinder is arranged on the workbench 10, and the first pressing block 31 is connected to the top of the rotating and pressing cylinder. Of course, in other embodiments of the present application, the first rotating and pressing mechanism 32 can also include a rotating cylinder and a lifting cylinder. For example, the rotating cylinder is arranged on the workbench 10, the lifting cylinder is arranged on the rotating cylinder, the first pressing block 31 is connected to the lifting cylinder, when the rotating cylinder rotates, it drives the lifting cylinder and the first pressing block 31 to rotate simultaneously, and when the lifting cylinder moves up and down, it drives the first pressing block 31 to rise and press down.

[0043] Optionally, the number of the first positioning columns 20 is two, three, four, etc.

[0044] Please refer to Figures 1 to 3, in an embodiment of the present application, the number of the first pressing and fixing devices 30 is four. Two of the first pressing and fixing devices 30 are arranged at intervals along the length direction of the processing area 11 on one side of the processing area 11, and the other two first pressing and fixing devices 30 are arranged at intervals along the length direction of the processing area 11 on the other side of the processing area 11.

[0045] Wherein, the length direction of the processing area 11 is consistent with the length direction of the leg housing 100. In this way, during the processing of the opposite sides of the leg housing 100 along its own length direction, when one of the first pressing and fixing devices 30 on the same side of the processing area 11 needs to avoid the leg housing 100, the other first pressing and fixing device 30 can be used to position the leg housing 100, such as Figure 2 and Figure 3 , so that during the processing of the leg housing 100, at least one first pressing and fixing device 30 is provided on both sides of the leg housing 100 along its own length direction to position the leg housing 100, effectively ensuring the stability of positioning the leg housing 100.

[0046] Of course, in other embodiments, the number of the first pressing and fixing devices 30 can also be other numbers, for example, two, three, five or more. At the same time, the circumferential layout manner of the multiple first pressing and fixing devices 30 can also be designed according to requirements.

[0047] Please refer to Figure 1 , in an embodiment of the present application, the robot leg housing processing jig further includes a second pressing and fixing device 40. The second pressing and fixing device 40 is arranged on the workbench 10 and is located outside one end of the processing area 11.

[0048] Specifically, please refer to Figure 5 , the second pressing and fixing device 40 includes a second pressing block 41 and a second rotary pressing mechanism 42 that connects the second pressing block 41 and is used to drive the second pressing block 41 to rotate and move up and down. A pressing column 43 is arranged at one end of the second pressing block 41 that can extend horizontally above the processing area 11.

[0049] When the leg housing 100 is placed in the processing area 11, the upper surface height of one end of the leg housing 100 close to the second pressing and fixing device 40 is lower than the upper surface height of other parts of the leg housing 100. Thus, when the second pressing and fixing device 40 positions one end of the leg housing 100, the second rotary pressing mechanism 42 is used to drive the second pressing block 41 to rotate and press down, so as to rotate the second pressing block 41 above the processing area 11, and the second pressing block 41 presses on the upper surface of one end of the leg housing 100 through the pressing column 43, such as Figure 2 and Figure 3. The second rotation and pressing mechanism 42 of the second pressing and fixing device 40 drives the second pressing block 41 to perform rotation and lifting movements, so that the second pressing block 41 automatically presses on the leg housing 100 and automatically moves away from the leg housing 100. It has a high degree of automation and is convenient to operate, which is beneficial to improving the processing efficiency and reducing the manual labor volume.

[0050] In an embodiment of the present application, the second rotation and pressing mechanism 42 is a rotation and pressing cylinder. The rotation and pressing cylinder is arranged on the workbench 10, and the second pressing block 41 is connected to the top of the rotation and pressing cylinder. Of course, in other embodiments of the present application, the second rotation and pressing mechanism 42 may also include a rotation cylinder and a lifting cylinder. For example, the rotation cylinder is arranged on the workbench 10, the lifting cylinder is arranged on the rotation cylinder, and the second pressing block 41 is connected to the lifting cylinder. When the rotation cylinder rotates, it drives the lifting cylinder and the second pressing block 41 to rotate simultaneously. When the lifting cylinder performs lifting movements, it drives the second pressing block 41 to rise and press down.

[0051] Please refer to Figure 1 , in an embodiment of the present application, the robot leg housing processing fixture further includes a second positioning post 50. The second positioning post 50 is arranged on the workbench 10 and is located inside one end of the processing area 11 close to the second pressing and fixing device 40. The height of the second positioning post 50 is lower than the height of the first positioning post 20.

[0052] When the leg housing 100 is placed in the processing area 11, one end of the leg housing 100 close to the second pressing and fixing device 40 is in a suspended state relative to the workbench 10, and the height of the lower surface of one end of the leg housing 100 close to the second pressing and fixing device 40 is lower than the height of the lower surfaces of other suspended parts of the leg housing 100 relative to the workbench 10. Therefore, the second positioning post 50 with a height lower than that of the first positioning post 20 is used to support the lower surface of one end of the leg housing 100 close to the second pressing and fixing device 40, effectively improving the stability of the support for the leg housing 100.

[0053] Please refer to Figures 1 to 3 , in an embodiment of the present application, the robot leg housing processing fixture further includes a third pressing and fixing device 60. The third pressing and fixing device 60 is arranged on the workbench 10 and is located inside the other end of the processing area 11. Specifically, the third pressing and fixing device 60 is located inside one end of the processing area 11 far from the second pressing and fixing device 40.

[0054] The third pressing and fixing device 60 cooperates with the first pressing and fixing device 30 and the second pressing and fixing device 40 to position the leg housing 100 placed in the processing area 11, effectively improving the stability of the positioning of the leg housing 100 and improving the balance of the force on the leg housing 100.

[0055] Please refer to Figure 6In one embodiment of the present application, the third pressing and fixing device 60 includes a third pressing block 61 and a lifting drive mechanism 62 connected to the third pressing block 61 and used to drive the third pressing block 61 to perform lifting movement. The lifting drive mechanism 62 drives the third pressing block 61 to perform lifting movement, so that the third pressing block 61 is automatically pressed on the leg housing 100 and automatically moves away from the leg housing 100, with a high degree of automation and convenient operation.

[0056] See also Figure 6 and Figure 7 The third clamping and fixing device 60 also includes a connecting column 63, which is detachably connected to the lifting drive mechanism 62. A clamping cap 64 is provided at one end of the connecting column 63 away from the lifting drive mechanism 62. The third pressing block 61 is provided with a clearance hole 611 and a positioning hole 612 for the connecting column 63 to pass through. The clearance hole 611 is connected to the positioning hole 612, and the width of the clearance hole 611 is greater than the width of the clamping cap 64, and the width of the positioning hole 612 is less than the width of the clamping cap 64.

[0057] When the third clamping and fixing device 60 is needed to position the other end of the leg housing 100, before placing the leg housing 100 in the processing area 11, the connecting column 63 is first removed from the lifting drive mechanism 62, and the leg housing 100 is placed in the processing area 11. At this time, the lower surface of the end of the leg housing 100 close to the third clamping and fixing device 60 is in contact with the workbench 10, and the end of the leg housing 100 close to the third clamping and fixing device 60 is provided with a mounting hole, and the connecting column 63 is passed through the mounting hole on the leg housing 100 and is connected to the lifting drive mechanism 62. 2, since the width of the clearance hole 611 is greater than the width of the clamping cap 64, the clamping cap 64 can pass through the clearance hole 611 on the third pressing block 61, so that the third pressing block 61 is sleeved on the connecting column 63, and the third pressing block 61 is moved in the horizontal direction so that the connecting column 63 is in a position to pass through the positioning hole 612. At this time, since the width of the positioning hole 612 is less than the width of the clamping cap 64, the third pressing block 61 cannot be separated from the clamping cap 64, and the lifting drive mechanism 62 drives the third pressing block 61 to descend, so as to press the third pressing block 61 on the leg housing 100.

[0058] Similarly, when the third clamping and fixing device 60 is no longer needed to position the leg shell 100, the lifting drive mechanism 62 drives the third clamping block 61 to rise, and moves the third clamping block 61 in the opposite direction in the horizontal direction, so that the connecting column 63 is in a position to pass through the clearance hole 611, and the third clamping block 61 is removed from the connecting column 63, and the connecting column 63 is removed from the lifting drive mechanism 62.

[0059] Optionally, the cross-sections of the connecting post 63 and the retaining cap 64 are both circular, and the diameter of the retaining cap 64 is greater than that of the connecting post 63. The relief hole 611 is a circular hole, and the inner diameter of the relief hole 611 is greater than the diameter of the retaining cap 64, so that the retaining cap 64 can pass through the relief hole 611. The positioning hole 612 is a strip-shaped hole, and the width of the positioning hole 612 is greater than the diameter of the connecting post 63 and less than the diameter of the retaining cap 64. Of course, the cross-sections of the connecting post 63 and the retaining cap 64 can also be other shapes, such as rectangular, elliptical, etc. Similarly, the relief hole 611 can also be a rectangular hole or an elliptical hole, and the positioning hole 612 can also be a circular hole, a rectangular hole, an elliptical hole, etc., as long as it is ensured that the retaining cap 64 can smoothly pass through the relief hole 611 and cannot pass through the positioning hole 612.

[0060] Optionally, the connecting post 63 is a screw or a bolt. A connecting hole is provided at the top of the lifting drive mechanism 62, and the connecting hole is a threaded hole. The connecting post 63 is inserted into the connecting hole on the lifting drive mechanism 62 and is threadedly engaged with the connecting hole to realize the detachable connection between the connecting post 63 and the lifting drive mechanism 62. Thus, the connecting post 63 can be removed from the lifting drive mechanism 62 or connected to the lifting drive mechanism 62 by screwing the connecting post 63. Of course, the connecting post 63 can also be inserted into the connecting hole on the lifting drive mechanism 62 and be in interference fit with the connecting hole to realize the detachable connection between the connecting post 63 and the lifting drive mechanism 62.

[0061] Please refer to Figure 1 , the robot leg housing processing fixture further includes at least two support seats 70, and the two support seats 70 are connected to the opposite ends of the workbench 10.

[0062] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
