Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] like figure 1 , the electromagnetic hammer and the thermometer are fixed together with a special fixture, the hammer head of the electromagnetic hammer and the welding torch are on the same plane perpendicular to the weldment, the hammer head and the temperature sensor point to the same point of the weld bead, and make the irradiation of the thermometer Diameter: smaller than the diameter R of the weld bead (generally r<0.5R). Start the thermometer at the same time as the welding starts, and transmit the weld bead temperature collected by the thermometer to the single-chip microcomputer through the A / D converter, compare it with the optimized temperature value stored in the single-chip microcomputer, and determine whether this position is suitable according to the comparison result hammer position. Then determine the appropriate hammering parameters (hammering ...

Abstract

The invention provides an automatic control circuit for welding with trailing peening. According to the circuit, an AT89C52 single-chip microcomputer acts as the core, a self-designed electromagnetic hammer acts as equipment for welding with trailing peening, temperature acquisition is performed on a welding bead in a tracking way by using a noncontact online infrared thermodetector, and a stepping motor acts as a driving device. The peening parameters can be accurately controlled by the circuit, the welding pores and fractures and other defects of a test piece can be obviously improved, the system is easy to control and can perform quick startup and shutdown and accurate positioning, the circuit is compact in structure, high in control accuracy, high in efficiency and great in adaptability, and the cost is reduced so that the objective of automatic welding with trailing peening can be realized.

Description

technical field [0001] The invention relates to an automatic control circuit of hammering with welding, which is suitable for modern pneumatic hammering with welding device. Background technique [0002] Agricultural machinery maintenance and repair work is an important part of agricultural engineering mechanization. It is a service activity to maintain and restore the good technical state of machinery, ensure its high operating efficiency and prolong the service life of machinery and tools. Surfacing welding is a very effective equipment repair method, which is widely used in the repair of agricultural machinery shaft parts. The crankshaft is one of the most important and expensive parts of an internal combustion engine. During work, the surface of the journal is susceptible to abrasive wear due to high-speed and extreme load movement and poor heat dissipation of the journal, so the requirements for machining accuracy and assembly accuracy of the journal are very strict. ...
