[0019] See also Figure 1 - Figure 4 The utility model provides a technical solution: a grasping mechanism based on a multi-axis manipulator, comprising: a support base 1; a manipulator device 2, the outer wall of the manipulator device 2 is slidably connected to the inner wall of the support base 1; a rotating device 3, the top of the rotating device 3 is fixedly connected to the bottom of the manipulator device 2; a grasping device 4, the grasping device 4 is symmetrically arranged at the bottom of the rotating device 3, and the outer wall of the grasping device 4 is fixedly connected to the outer wall of the rotating device 3; the grasping device 4 includes a second cylinder 41 and a third cylinder 42, the tops of the second cylinder 41 and the third cylinder 42 are fixedly connected to the bottom of the rotating device 3, the piston rods of the second cylinder 41 and the third cylinder 42 are fixedly connected to the support rod 43, and the support rod 43 The bottom is symmetrically fixed with a clamping rod 44. When in use, the second cylinder 41 and the third cylinder 42 in the grasping device 4 are started, and the gas enters the cylinder to push the piston rod to move, and the piston rod drives the support rod 43 to move. Since the bottom of the support rod 43 is symmetrically connected to the clamping rod 44, when the support rod 43 moves, the clamping rod 44 will move accordingly. The bottom of the clamping rod 44 adopts a frustum-shaped structure, which is more conducive to contact and stable clamping of objects. Through the action of the cylinder, the clamping rod 44 can realize opening and closing actions. Since the grasping device 4 is symmetrically arranged on the bottom of the support plate 34, when the clamping rod 44 is closed, two objects can be clamped at the same time, completing the grasping operation and improving work efficiency.
[0020] The manipulator device 2 includes a first connecting rod 21, the outer wall of the first connecting rod 21 is slidably connected to the outer wall of the support seat 1, the inner wall of the first connecting rod 21 is slidably connected to the first drag chain 22, the end of the first drag chain 22 away from the first connecting rod 21 is fixedly connected to the second connecting rod 23, the outer wall of the second connecting rod 23 is fixedly connected to the second drag chain 24, and the second drag chain 24 is fixedly connected to the third connecting rod 25 on one end of the second connecting rod 23.
[0021] The outer wall of the second connecting rod 23 is slidably connected to the inner wall of the first connecting rod 21, and the outer wall of the third connecting rod 25 is slidably connected to the inner wall of the second connecting rod 23. When in use, the support seat 1 is used to support the entire equipment. In terms of the movement of the manipulator device 2, the first connecting rod 21 slides on the inner wall of the support seat 1 to achieve initial position movement, and the second connecting rod 23 is driven by the first drag chain 22 to slide on the inner wall of the first connecting rod 21, and the third connecting rod 25 is driven by the second drag chain 24 to slide on the inner wall of the second connecting rod 23. This series of sliding connection combinations enables the manipulator to flexibly adjust its position in multiple directions, thereby moving the grasping device 4 to a suitable position above the target object.
[0022] The rotating device 3 includes a first cylinder 31 , a piston rod of the first cylinder 31 is fixedly connected to a rack 32 , and an outer wall of the first cylinder 31 is rotatably connected to an intermittent gear 33 .
[0023] The top of the first cylinder 31 is fixedly connected to the bottom of the third connecting rod 25 , and the bottom of the intermittent gear 33 is fixedly connected to a support plate 34 .
[0024] The rack 32 is meshed with the intermittent gear 33, and the bottom of the clamping rod 44 adopts a truncated cone structure. When in use, the first cylinder 31 in the rotating device 3 works, and the piston rod pushes the rack 32 to move. Since the rack 32 is meshed with the intermittent gear 33, when the rack 32 moves, it will drive the intermittent gear 33 to rotate. Because the intermittent gear 33 has only a quarter of the teeth, under the action of the rack 32, the intermittent gear 33 can achieve a ninety-degree flip, thereby driving the bottom support plate 34 to rotate, adjusting the angle of the grasping device 4 to better align with the object.
[0025] Working principle:
[0026] When in use, the support base 1 is used to support the entire device. In terms of the movement of the manipulator device 2, the first connecting rod 21 slides on the inner wall of the support base 1 to achieve preliminary position movement. The first drag chain 22 drives the second connecting rod 23 to slide on the inner wall of the first connecting rod 21. The second drag chain 24 drives the third connecting rod 25 to slide on the inner wall of the second connecting rod 23. This series of sliding connection combinations enables the manipulator to flexibly adjust its position in multiple directions, thereby moving the grasping device 4 to a suitable position above the target object;
[0027] When in use, the first cylinder 31 in the rotating device 3 works, and the piston rod pushes the rack 32 to move. Since the rack 32 is engaged with the intermittent gear 33, when the rack 32 moves, it drives the intermittent gear 33 to rotate. Because the intermittent gear 33 has only a quarter of a tooth, the intermittent gear 33 can achieve a 90-degree flip under the action of the rack 32, thereby driving the bottom support plate 34 to rotate, adjusting the angle of the grasping device 4 to better align with the object;
[0028] During use, the second cylinder 41 and the third cylinder 42 in the grasping device 4 are started, and the gas enters the cylinder to push the piston rod to move, and the piston rod drives the support rod 43 to move. Since the bottom of the support rod 43 is symmetrically connected to the clamping rod 44, when the support rod 43 moves, the clamping rod 44 will move accordingly. The bottom of the clamping rod 44 adopts a truncated cone structure, which is more conducive to contact and stable clamping of objects. Through the action of the cylinder, the clamping rod 44 can realize opening and closing actions. Since the grasping device 4 is symmetrically arranged on the bottom of the support plate 34, when the clamping rod 44 is closed, two objects can be clamped at the same time, completing the grasping operation and improving work efficiency.
