An Automatic Executing Mechanism Suitable for Residual Stress Relief Device

Abstract

The invention relates to an automatic executing mechanism suitable for a residual stress eliminating device. The automatic executing mechanism comprises a machine frame, self-adsorption mechanisms used for controlling moving walking are arranged on the two sides of the machine frame correspondingly, a three-axis linkage mechanism is arranged on the surface of the machine frame, a first connectingseat is fixedly connected on a sliding seat of a Z-axis sliding table of the three-axis linkage mechanism, one end of a cantilever is movably connected with the first connecting seat so that the cantilever can move up and down relative to the first connecting seat, the other end of the cantilever is connected with a second connecting seat through pins, the outer side of the second connecting seatis connected with a rotary table through a fastener, and an end seat of an ultrasonic wave output device is in pin joint on the rotary table through a pin shaft. According to the mechanism, the structure is simple, the use is convenient, the mechanism has functions of performing translation in the transverse direction, in the longitudinal direction and the vertical direction and rotating along a transverse axis and a longitudinal axis, the posture and the position of the ultrasonic wave output device can be timely adjusted, and accurate processing of residual stress is achieved.

Description

technical field [0001] The invention relates to the field of ocean ship engineering, in particular to an automatic actuator suitable for a residual stress relief device, which has five degrees of freedom adjustment functions and is equipped with an adsorption system and a monitoring system, and can be used on the upper, lower, and side surfaces of steel structures Suction walking works. Background technique [0002] At present, ships and marine engineering structures are mostly made of high-strength materials. Compared with general materials, high-strength materials have higher sensitivity to welding residual stress. When workpieces are assembled and welded, large welding residual stresses are often generated. reduce structural performance. Therefore, it is of great significance to reduce the residual stress in the structure for ship and ocean engineering structures. Ships and marine engineering structures are large-scale welded structures, with a large number of welds and...

Problems solved by technology

[0003] (1) The processing position is inaccurate. In the working state, the impact needle at the front end of the impact gun vibrates at high speed, which causes the entire impact gun to vibrate continuously, making it impossible to accurately align the metal surface to be processed manually, which may cause some metals to be untreated. or excessive processing;

[0004] (2) The treatment intensity is uneven. The stress relief treatment usually requires two to three times of treatment, so that the impact marks all cover the metal surface to be treated. Due to the instability of manual labor, the treatment intensity may be uneven;

[0005] (3) The labor intensity is high and the efficiency is low. Due to the small cross-sectional area of ​​the impact needle at the front end of the impact gun, the metal surface treated by one impact is also very small, which leads to a long time for stress relief treatment, and the correspondingly long working hours. many
