Full-automatic necking-in device for high lock nut

Abstract

The invention discloses a full-automatic necking-in device for a high lock nut. The device comprises a frame and a vibrating plate, a direct vibrator, a stopping and separating mechanism, a station manipulator, a necking-in functional unit, a control box, an electric box and a receiving box which are arranged on the frame, wherein the high lock nut is transferred from the vibrating plate to the direct vibrator and then to the stopping and separating mechanism in turn; the station manipulator comprises a cross beam which can move up and down as well as left and right; claws are respectively arranged at the left and right ends of the cross beam; the necking-in functional unit comprises a mounting flange, a clamping plate, necking-in press heads, a pressure sensor, a differential screw adjusting mechanism, a lifting adjusting device and a motor; at least two necking-in press heads are uniformly distributed on the circumference of the clamping plate; and arc-shaped pressing notches are arranged at the front end of the necking-in press heads and are used for necking-in the high lock nut which is clamped between the arc-shaped pressing notches in a necking-in process. The full-automatic necking-in device for the high lock nut has the advantages of compact structure, convenience in operation, reliability in use and high efficiency. The end product of the high lock nut after being necked-in is excellent in use property and is difficult to crack.

Description

technical field [0001] The invention belongs to the field of mechanical parts processing, and in particular relates to a fully automatic closing device for high lock nuts. Background technique [0002] The main difference between the high lock nut and the ordinary nut is that the high lock nut can obtain the specified locking torque and loosening torque after installation, and it is not easy to loosen and fall off during use, and has high safety; therefore, the high lock nut is widely used It is used in aerospace products and other fields; the expected tightening torque and loosening torque of high-lock nuts are obtained through the closing process; therefore, the closing process is a necessary key process for high-lock nut processing, which needs to be performed on a special closing machine. [0003] The currently commonly used closing machine has a complex structure and cumbersome operation. Generally, the closing process is controlled by manual assistance. Its processing ...
