DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Embodiment 1:
[0020] Please refer to Figures 1-4 Figures 1-4 , the present utility model provides a technical solution: including a bottom plate 1, a front moving and fixing component 2 and a rear moving and fixing component 3 are arranged on the surface of the bottom plate 1. The front moving and fixing component 2 includes a first stepping motor 21 arranged on the surface of the bottom plate 1. The output end of the first stepping motor 21 is rotationally connected to a first guide screw 22. The first guide screw 22 is rotationally connected to a first moving block 23. On the surface of the first moving block 23, a connecting block 24 is fixedly arranged. On the surface of the connecting block 24, a foot surface fixing arc plate 25 is fixedly arranged. The heel limiting block 34 has a right-angled structure; the rear moving and fixing component 3 includes a second stepping motor 31. The output end of the second stepping motor 31 is rotationally connected to a second guide screw 32. The second guide screw 32 is rotationally connected to a second moving block 33. On the surface of the second moving block 33, a heel limiting block 34 is fixedly arranged; a placing block 4 is arranged between the front moving and fixing component 2 and the rear moving and fixing component 3. On the left and right sides of the surface of the placing block 4, a limiting plate 41 is arranged on each side. Limiting plates 41 are arranged on the left and right of the surface of the placing block 4 to prevent the left and right movement when the feet of the humanoid robot are clamped, resulting in clamping damage.
[0021] Wherein, the inner surface of the foot surface fixing arc plate 25 and the surface of the placing block 4 are on the same horizontal plane. When the feet of the humanoid robot are placed on the surface of the placing block 4, the front moving and fixing component 2 and the rear moving and fixing component 3 move towards the placing block 4 at the same time to fix the feet of the humanoid robot. And the inner surface of the foot surface fixing arc plate 25 and the surface of the placing block 4 are on the same horizontal plane, making the fixing more stable and fast, and avoiding damage to the feet of the humanoid robot caused by the inner surface of the foot surface fixing arc plate 25 and the surface of the placing block 4 not being on the same horizontal plane when clamping and fixing.
[0022] Embodiment 2:
[0023] Please refer to Figures 1-4 Figures 1-4 , the present utility model provides a technical solution: a limiting part 5 is further arranged on the surface of the bottom plate 1 of the device. The limiting part 5 includes a first limiting block 51. A second limiting block 52 corresponding to the first limiting block 51 is arranged on the surface of the bottom plate 1. The first guide screw 22 passes through the first limiting block 51 adjacent to the first stepping motor 21 and is rotationally connected to the second limiting block 52 adjacent to the first stepping motor 21. The second guide screw 32 passes through the first limiting block 51 adjacent to the second stepping motor 31 and is rotationally connected to the second limiting block 52 adjacent to the second stepping motor 31, restricting the left and right moving distances of the front moving and fixing component 2 and the rear moving and fixing component 3.
[0024] A guiding part is also arranged between the first limiting block 51 and the second limiting block 52. The guiding part includes rail fixing parts 61 symmetrically arranged on the surface of the bottom plate 1, and guiding rods 62 are arranged on the surfaces of the rail fixing parts 61. Sliders 63 are arranged on the left and right sides of the connecting block 24 and the second moving block 33 respectively. The sliders 63 are slidably connected with the guiding rods 62. Through the guiding part, the first moving block 23 drives the foot fixing arc plate 25 to move, and the second moving block 33 drives the heel limiting block 34 to move more smoothly. Through the sliders 63 on the left and right sides of the connecting block and the second moving bottom, when fixing the humanoid robot's foot towards the second limiting block 52, it is more firm.
[0025] An induction device 7 is also arranged on one side of the first limiting block 51. The induction device 7 includes an induction head 71. The induction head 71 is arranged on the first limiting block 51 and extends towards the second limiting block 52. The induction device 7 is electrically connected to the stepping motor. When the induction head 71 touches the moving block, the stepping motor stops operating, so that the moving block stops moving.
[0026] Working principle:
[0027] First, the first stepping motor 21 drives the first guide screw 22 to rotate, so that the first moving block 23 drives the foot fixing arc plate 25 to move towards the first stepping motor 21. When the front end of the foot fixing arc plate 25 touches the touch head, the first stepping motor 21 stops operating and the first moving block 23 stops moving. The second stepping motor 31 drives the second guide screw 32 to rotate, so that the second moving block 33 drives the heel limiting block 34 to move towards the second stepping motor 31. When the rear side of the heel limiting block 34 touches the touch head, the second stepping motor 31 stops operating and the second moving block 33 stops moving. At this time, the humanoid robot's foot is placed on the surface of the placing block 4 and located between the limiting plates 41. Then start the first stepping motor 21 and the second stepping motor 31. Through the rotation of the first guide screw 22 and the second guide screw 32, drive the foot fixing arc plate 25 and the heel limiting block 34 to move towards the placing block 4 until the foot fixing arc plate 25 and the heel limiting block 34 clamp and fix the humanoid robot's foot, and then conduct tests on the humanoid robot.
