Self-balance fine adjusting system of welding machine

Abstract

The invention relates to a self-balance fine adjusting system of a welding machine. A pressure sensor is arranged in each of pedestals, below the four corner positions, of a base. Four horizontal sensors are arranged on the upper end face of the base at intervals. Output signals of the four pressure sensors and the horizontal sensors are transmitted to an upper computer. The outer edge of each fixing nut is sleeved with an adjusting rod. A piston rod of an oil cylinder is hinged to the end portion of the outer side of each adjusting rod. A control signal about whether the four piston rods actor not is output through the upper computer. In the self-balance fine adjusting system of the welding machine, the pressure sensors are used for detecting the pressure generated at the four corner positions of the base, the horizontal sensors are used for detecting the levelness of the base, and the two sets of data are transmitted to the upper computer in a wireless manner. The upper computer drives the oil cylinders to drive the adjusting rods so as to drive fixing nut rotating or tightness adjusting or loosening adjusting, and dynamic balance fine adjustment of the welding machine during work can be achieved.

Description

technical field [0001] The invention belongs to the technical field of improving the balance structure of welding machines, in particular to a welding machine self-balancing fine-tuning system. Background technique [0002] Welding machine is a commonly used processing equipment in auto parts manufacturing enterprises. It has the characteristics of high degree of automation and precise processing. Since the welding machine needs to input the spatial coordinates when pre-programming, this requires that the installation position of the welding machine must maintain a high-precision level . In the prior art, it is first necessary to excavate at the installation location, then install steel bars, and then pour concrete to form a base. After the base is solidified, the welding machine is fixed by the external threads and fixing nuts on the upper end of the pre-embedded steel bars in the base. The base of the lower end, thus completing the precise installation of the welding mach...

Problems solved by technology

In actual use, it is found that the manipulator in the welding machine moves fast and has a high frequency, and after long-term use, the balance will be poor. Of course, the inclination angle after measurement is small, but it will also affect the machining accuracy of the manipulator. When it is necessary to stop the machine, the operator can adjust the base or adjust the upper mechanism of the welding machine to correct it, but both methods take a long time, and the adjustment effect is not very good
