Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-3, the present invention provides the following technical solutions: a robot automatic die changing clamping jaw comprises a fixed block 1, a connecting block 2 is arranged in the middle of the fixed block 1, an air cylinder 7 is arranged on one side of the fixed block 1, one end of the connecting block 2 is fixedly connected with the air cylinder 7 through a bolt, a sensor 3 is fixed above the connecting block 2, the sensor 3 is fixedly connected with the fixed block 1 through a screw, a transition block 4 is arranged below the connecting block 2, the transition block 4 is fixedly connected with the connecting block 2 through welding, a left hook rod 5 and a right hook rod 6 are arranged at the bottom end of the fixed block 1, the left hook rod 5 is elastically connected with the right hook rod 6, a die waist-shaped groove is formed in the middle of the left hook rod 5 and the right hook rod 6, an integrated polyurethane pad 9 is fixed inside the die waist-shaped groove, a die 8 is placed inside the die waist-shaped groove, in the embodiment, a die below 6 kilograms can be clamped through the design, the phenomenon that the die does not shake in the die changing process is ensured.

Concretely, the protruding position in top of transition piece 4 is fixed mutually through the welding with connecting block 2, and the bottom of transition piece 4 is inserted into with left hooked rod 5 and the 6 front end parts of right hooked rod, in this embodiment, through cylinder 7, drives connecting block 2 to the side motion, and then drives transition piece 4 toward same direction motion for the device produces a series of motions, and the convenience is pressed from both sides tightly the mould.
