[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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.
[0023] Refer to Figures 1-5 , a manipulator placing nut fixture, including a first fixed plate 1 and a second fixed plate 2, the first fixed plate 1 and the second fixed plate 2 are fixedly connected by a connecting column, at least four mounting holes 21 are provided on the second fixed plate 2, an adjusting mechanism 3 is provided on the mounting hole 21, a grasping assembly 22 is slidably connected to the adjusting mechanism 3, and the adjusting mechanism 3 is used for adjusting the height of the grasping assembly 22. In the present utility model, the height of the grasping assembly 22 can be adjusted through the adjusting mechanism 3, and the manipulator can flexibly adjust the position of the grasping assembly according to different nut fixture heights or size requirements, so as to ensure the accuracy and efficiency of the grasping operation;
[0024] Among them, a limit mechanism 4 is provided on the grasping assembly 22, the limit mechanism 4 is used to limit the grasping assembly 22, and a guiding member 5 is also provided in the mounting hole 21, and the guiding member 5 is used for guiding the grasping assembly 22. In the present utility model, the limit mechanism 4 is located at the upper end of the adjusting mechanism 3. When the adjusting mechanism 3 moves up and down, the limit mechanism 4 will move accordingly, ensuring that the grasping assembly 22 can move up and down synchronously, preventing the grasping assembly 22 from falling off the adjusting mechanism 3 during the adjustment process, and at the same time making the disassembly of the grasping assembly 22 simpler and faster. In addition, the guiding member 5 prevents the grasping assembly 22 from rotating in the mounting hole 21 and affecting the grasping effect.
[0025] Further, the grasping component 22 includes a suction cup connecting rod 221. One end of the suction cup connecting rod 221 is provided with a clamping groove 222, and a vacuum suction cup 223 is clamped on the clamping groove 222. A buffer spring 224 is arranged on the surface of the suction cup connecting rod 221. In the present utility model, the buffer spring 224 can absorb and disperse the impact force and vibration generated during the grasping or releasing operation, thereby reducing the damage to the vacuum suction cup 223 and the grasped fixture. When it is necessary to maintain or replace the vacuum suction cup 223, it can be easily disassembled through the clamping method of the clamping groove 222, improving the maintenance efficiency.
[0026] Furthermore, the adjusting mechanism 3 includes a sleeve 31. The sleeve 31 is slidably connected to the mounting hole 21, and the suction cup connecting rod 221 is slidably connected to the sleeve 31. An installation groove 32 is arranged in the second fixing plate 2, and the installation groove 32 communicates with the mounting hole 21. One side of the sleeve 31 is fixedly connected with a rack 33, and a gear 34 is rotatably connected in the installation groove 32. The rack 33 is meshed with the gear 34. In the present utility model, when it is necessary to adjust the height of the grasping component 22, the gear 34 can be rotated. Since the rack 33 is meshed with the gear 34, the rotation of the gear 34 will drive the sleeve 31 to move up and down along the mounting hole 21, thereby realizing the height adjustment of the grasping component 22.
[0027] Wherein, a connecting rod 35 is fixedly connected to one side of the gear 34. One end of the connecting rod 35 passes through the installation groove 32 and is provided with a knob 36 at the end. A bolt 37 is threadedly connected to the second fixing plate 2, and one end of the bolt 37 abuts against the connecting rod 35. In the present utility model, rotating the knob 36 will directly drive the connecting rod 35 and the gear 34 fixed thereto to rotate together. The gear 34 is meshed with the rack 33, pushing the sleeve 31 to move up and down along the thread. The movement of the sleeve 31 will drive the connected grasping component 22 to move up and down synchronously, realizing the function of adjusting the height of the grasping component 22. When the adjustment is completed, by rotating the bolt 37, the connecting rod 35 is fixed to prevent the gear 34 from rotating.
[0028] In addition, a notch 225 is provided on the surface of the upper end of the sucker connecting rod 221. The limiting mechanism 4 includes two T-shaped blocks 41 which are slidably connected to the notch 225. In this embodiment, a clamping block is fixedly connected to the inner wall of the notch 225 for fixing the T-shaped block 41 to prevent it from falling off. A spring 42 is arranged between the two T-shaped blocks 41. The lower end of the T-shaped block 41 abuts against the upper end of the sleeve 31. In the present utility model, the elastic force of the spring 42 is used to push the lower end of the T-shaped block 41 against the upper end of the sleeve 31, thereby fixing the sucker connecting rod 221 to prevent it from falling. When the sucker connecting rod 221 needs to be disassembled, by pressing the T-shaped block 41 to make it retract, the sucker connecting rod 221 is no longer fixed and can be easily taken out from the adjusting mechanism 3, making the disassembly of the sucker connecting rod 221 more convenient. At the same time, it is convenient to replace or maintain other components such as the buffer spring 224.
[0029] Furthermore, the guiding member 5 includes a guiding post 51 which is fixedly connected to the inner wall of the mounting hole 21. A guiding groove 52 is provided on the surface of the sucker connecting rod 221. A notch is provided on one side of the sleeve 31. One end of the guiding post 51 passes through the notch and is slidably connected to the guiding groove 52. In the present utility model, through the sliding connection between the guiding post 51 and the guiding groove 52, it is ensured that the sucker connecting rod 221 can only move in a straight line direction during the adjustment process and will not rotate, effectively preventing the instability of the sucker connecting rod 221 during the grasping operation and ensuring the accuracy of the grasping effect.
[0030] Working mode: During operation, rotating the knob 36 will directly drive the connecting rod 35 and the gear 34 fixed thereto to rotate together. The gear 34 meshes with the rack 33 to push the sleeve 31 to move up and down along the thread. The movement of the sleeve 31 further drives the connected grasping assembly 22 to move up and down synchronously, realizing the function of adjusting the height of the grasping assembly 22. When the adjustment is completed, by rotating the bolt 37 to fix the connecting rod 35 to prevent the gear 34 from rotating. Through the sliding connection between the guiding post 51 and the guiding groove 52, it is ensured that the sucker connecting rod 221 can only move in a straight line direction during the adjustment process and will not rotate, effectively preventing the instability of the sucker connecting rod 221 during the grasping operation and ensuring the accuracy of the grasping effect. The elastic force of the spring 42 is used to push the lower end of the T-shaped block 41 against the upper end of the sleeve 31, thereby fixing the sucker connecting rod 221 to prevent it from falling. When the sucker connecting rod 221 needs to be disassembled, by pressing the T-shaped block 41 to make it retract, the sucker connecting rod 221 is no longer fixed and can be easily taken out from the adjusting mechanism 3, making the disassembly of the sucker connecting rod 221 more convenient. At the same time, it is convenient to replace or maintain other components such as the buffer spring 224.
