Description

Technical Field

[0001] The utility model relates to the technical field of mechanical claws, in particular to a mechanical claw that can be adjusted in multiple directions. Background Art

[0002] The robot arm is mainly composed of three parts: the actuator, the drive mechanism and the control system. The hand is the component used to grasp the workpiece, and there are various structural forms depending on the shape, size, weight, material and operation requirements of the grasped object.

[0003] After searching, the announcement number CN206230505U discloses a variable-angle mechanical claw. When grabbing a cylindrical object, the combination of the rotating bearing and the connecting rod drives the rotation so that the mechanical claw is symmetrically distributed at 90°. Starting the hydraulic cylinder makes the fixed sleeve move downward along the handle, and the mechanical claw retracts to grasp the object. The device has the function of rotating clamping. When the mechanical claw is rotating and grasping, the human hand is required to control the mechanical claw all the time. When the mechanical claw is moving, it may cause injury to the human hand, thereby affecting the health of the workers. Utility Model Content

The electric telescopic rod 6 is extended to make the overall parallel movement of the clamping assembly longer, and a second hydraulic cylinder 7 is fixed to the extended end of the electric telescopic rod 6 by bolts, and one end of the hydraulic rod of the second hydraulic cylinder 7 is rotatably connected to a rotating block 14, a convex ring is welded on the outer side of the second hydraulic cylinder 7, and a swivel 16 is slidably connected to the outer side of the convex ring, and a plurality of thread holes 18 are opened inside the swivel 16, and a third fixed block 12 is fixed to the top of the second hydraulic cylinder 7 by bolts, and a screw 11 is rotatably connected to the inner side of the third fixed block 12, and the screw 11 is threadedly connected to the thread hole 18, and the swivel 16 is rotated to drive the clamping assembly to rotate to the required position as a whole, and then the screw 11 is rotated to insert it into the thread hole 18 at the corresponding position, so that the adjusted angle is fixed, and a clamping assembly for clamping objects is provided on one side of the swivel 16.

[0024] The clamping assembly includes a rotating frame 8, which is fixed to one side of a rotating ring 16 by bolts. A rotating block 14 slides inside the rotating frame 8. The upper surface of the rotating block 14 is rotatably connected to two connecting rods 9. One end of the rotating frame 8 is rotatably connected to two clamping rods 10, and the clamping rods 10 are rotatably connected to the connecting rods 9. The second hydraulic cylinder 7 is extended to make the rotating block 14 move along the rotating frame 8, so that the connecting rods 9 drive the clamping rods 10 to rotate inward to clamp the object. A first fixed block 2 is fixed to one side of the bottom plate 1 by bolts, and a first hydraulic cylinder 3 is rotatably connected to one side of the first fixed block 2. The outer side of the electric telescopic rod 6 is fixed by bolts. A fixed ring 5 is provided, and the fixed ring 5 is rotatably connected to one end of the hydraulic rod of the first hydraulic cylinder 3. The first hydraulic cylinder 3 extends to pull the electric telescopic rod 6 to rotate upward, so that the staff can drive the clamping assembly to swing the clamped object upward to a suitable height according to needs. A plurality of rolling balls 13 are rotatably connected to the outer side of the convex ring.
