Detailed Description

The present invention will be described in more detail with reference to the accompanying drawings.

As shown in fig. 1, a cross beam 1 is installed on a tapping machine, the cross beam 1 is of a square tube structure, the upper surface of the square tube cross beam is horizontally arranged, two sets of blanking devices 2 are installed on the cross beam 1 in parallel, and the tapping machine is not shown in the drawing.

Each blanking device is structurally shown in fig. 2, a first cylinder 21 is horizontally arranged on the upper surface of the square tube beam, and the motion direction of a piston rod of the first cylinder is vertical to the length direction of the beam; a second cylinder 22 is fixedly connected with the end plate of the tail end of the piston rod of the first cylinder, the second cylinder 22 is vertical to the first cylinder 21, the piston rod of the second cylinder 22 is vertically downward, the end plate of the piston rod end of the first cylinder is connected with the second cylinder through a first connecting plate 211 which is vertically arranged, a slide block 212 is fixedly arranged on the upper surface of the first cylinder 21, a second connecting plate 213 which is horizontally arranged is arranged on the slide block, a guide rail 214 is fixedly arranged on the lower surface of the second connecting plate 213, the guide rail 214 is clamped and limited by a slide block 213 positioned below the guide rail 214, the other end of the second connecting plate 214 is fixedly connected with the first connecting plate 211, the first air cylinder 21 and the second air cylinder 22 are double-link air cylinders, two piston rods are arranged, so that the thrust is doubled, and the end plate connects two piston rods together the piston rod resist the gyration high precision, the cooperation of guide rail and slider has played fine direction location effect in addition.

A bracket 23 is fixedly connected to the end plate of the piston rod of the second cylinder 22, and three mechanical claws 231 are arranged in parallel on the bracket 23 at equal intervals and can grab three machined nut workpieces at the same time. The mechanical gripper 231 comprises a pneumatic finger 2311 which is two
