Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

1-4, a pneumatic clamping jaw includes a mounting plate 1, four fixing blocks 3 are fixedly connected to the bottom of the mounting plate 1, and the other ends of the four fixing blocks 3 are hinged with a clamping jaw 4, and one side of the clamping jaw 4 is fixed A fixing ring 14 is connected, a connecting rope 16 is fixedly connected to the fixing ring 14, the other end of the connecting rope 16 is fixedly connected with a plunger 15, a claw head 13 is arranged in the clamping claw 4, and a cylinder 2 is fixedly connected to the mounting plate 1. 2 is the prior art, and I will not make a statement here. The output end of the cylinder 2 is fixedly connected with a No. 1 connecting plate 5, and the four sides of the No. 1 connecting plate 5 are hinged with a No. 1 supporting rod 6. The bottom of the No. 1 connecting plate 5 is fixedly connected with The sleeve 7 is slidably connected with a sliding rod 8 , the bottom of the sliding rod 8 is fixedly connected with a No. 2 connecting plate 9 , and a spring 10 is sleeved on the outer surface of the sleeve 7 .

Further, referring to FIGS. 3 and 4 , it can be known that the clamping jaw 4 is provided with a groove 11 , and the groove 11 corresponds to the claw head 13 , the claw head 13 slides in the groove 11 , and the groove 11 is provided with a groove 11 . Damping rubber, the damping rubber is not shown in the picture.

Further, referring to FIG. 3, it can be known that both sides of the groove 11 and the claw head 13 are provided with insertion holes 17, and the insertion holes 17 correspond to the insertion rods 15, and both ends of the insertion rods 15 pass through the insertion holes 17 and Extend part.

Further, referring to FIG. 1 and FIG. 4, it can be known that the four No. 1 support rods 6 and No. 2 support rods 12 correspond to one clamping jaw 4 respectively, and the other ends of the No. 1 support rod 6 and the No. 2 support rod 12 are connected to the clamp. The claw 4 is hinged on one side.

Further, referring to FIG. 1 , both ends of the spring 10 are fixedly connected to the bottom of the No. 1 connecting plate 5 and the top of the No. 2 connecting plate 9 respectively, and the four No. 1 support rods 6 are respectively aligned with one No. 2 support rod 12 up and down.

This scheme has the following working process: when in use, the output end of the cylinder 2 is controlled to move up and down, thereby driving the No. 1 connecting plate 5 to move, and the movement of the No. 1 connecting plate 5 will pull one end of the No. 1 support rod 6 to move, so that the clamping jaw 4 Rotate, and the spring 10 has an upward pulling force on the No. 2 connecting plate 9, so that the No. 2 connecting plate 9 moves upward, and the movement of the No. 2 connecting plate 9 will pull the No. 2 support rod 12, and the No. 2 support rod 12 will pull the clamp. Claw 4, since the angle of the clamping jaw 4 is limited by the No. 1 support rod 6, the No. 2 support rod 12 will not change the angle of the clamping jaw 4, but will increase the clamping force of the clamping jaw 4, thereby preventing the clamping jaw. 4 The holding force is too small to clamp the workpiece.

Since the claw head 13 will also affect the clamping of the clamping jaw 4, the claw head 13 that does not conform to the workpiece will cause unstable clamping of the workpiece, so the claw head 13 needs to be replaced according to the workpiece. Then insert the new claw head 13 into the groove 11, align the groove 11 with the socket 17 on the claw head 13, and then insert the insertion rod 15.
