Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1-4, a mechanical clamping device with a self-locking function comprises a frame 1, a cylinder 2, a transmission rod 3 and two clamping claws 4;
the machine frame 1 is provided with an air cylinder fixing hole 11 and two clamping jaw mounting seats 12, and the two clamping jaw mounting seats 12 are symmetrically arranged on two sides of the air cylinder fixing hole 11 respectively;
the cylinder 2 comprises a cylinder body 21 and a piston rod 22, and the cylinder body 21 is fixedly connected with the rack 1 through a cylinder fixing hole 11;
a piston rod fixing hole 31 is formed in the middle of the transmission rod 3, the output tail end of the piston rod 22 is fixedly connected with the piston rod fixing hole 31, sliding rods 32 are symmetrically arranged on two sides of the transmission rod 3 respectively, and the sliding rods 32 are cylindrical;
two gripper jaw 4 symmetry respectively sets up the both sides at cylinder 2, be provided with object clamping part 41, from locked groove 42 and frame fixed orifices 43 on gripper jaw 4, object clamping part 41 and frame fixed orifices 43 are located the both sides from locked groove 42 respectively, gripper jaw 4 comes to articulate with gripper jaw mount pad 12 through frame fixed orifices 43, from locked groove 42 including the self-locking portion 421 and the portion 422 that opens and shuts that are linked together, self-locking portion 421 and piston rod 22 parallel arrangement, the portion 422 that opens and shuts inclines to extend towards piston rod 22 and sets up, from locked groove 42 and slide bar 32 adaptation, the tip of slide bar 32 is located from locked groove 42.
The object holding portion 41 has a "C" shape.
And a robot fixing hole 13 is also formed in the frame 1.
The transmission rod 3 is
The two slide bars 32 are respectively and symmetrically arranged at the bottoms of the two ends of the transmission rod 3; the structural design improves the structural stability of the transmission rod 3 and has good force transmission performance to the sliding rod 32.
The working principle of the embodiment is as follows: the clamping device of the embodiment is fixedly connected with the robot through the robot fixing hole 13 on the frame 1. When the two clamping jaws 4 are opened, the sliding rod 32 is located in the opening and closing portion 422 of the self-locking groove 42, then an object to be clamped is placed between the object clamping portions 41 of the two clamping jaws 4, the piston rod 22 of the air cylinder 2 extends outwards to push the transmission rod 3 to move, the sliding rod 32 on the transmission rod 3 moves along with the object to be clamped, due to the unique structural design of the self-locking groove 42, the self-locking groove 42 is matched with the sliding rod 32, and when the sliding rod 32 moves towards the self-locking portion 421 in the opening and closing portion 422, the two clamping jaws 4 are clamped with each other.
