Description

Robot aluminum welding pliers high thrust cylinder structure Technical Field The application relates to the technical field of aluminum welding tongs, in particular to a large-thrust cylinder structure of a robot aluminum welding tongs. Background The aluminum welding tongs are a welding tool specially designed for resistance spot welding of aluminum alloy materials, and compared with welding operation of other materials, the aluminum alloy materials have the characteristics of high heat conductivity, easy oxidation and the like, so that higher current and pressure and better cooling performance are required when the aluminum alloy materials are welded, thereby improving the welding quality and efficiency of the aluminum alloy materials; In order to ensure the stability of nugget forming during welding operation and reduce the generation of splashing and cracks, 0.2-8KN of pressure is required to be provided during welding, a pressurizing cylinder in the existing aluminum welding tongs is mostly integrated with a large piston and a small piston in a cylinder body, and the large piston is utilized to drive the small piston, so that the pressure of a common air source is converted into local high pressure to be output outwards, but the pressurizing mode leads the integral structure of the cylinder to be larger, the pressurizing coefficient to be lower, the using parameters of the aluminum welding tongs under the condition of large pressure are difficult to be satisfied, and the application range of the aluminum welding tongs is greatly limited; Meanwhile, the aluminum welding tongs have strict requirements on the overall stability when welding operation is carried out, and the pressurizing cylinder on the existing aluminum welding tongs only carries out locking and stopping operation on the aluminum welding tongs by means of air pressure, so that the phenomenon of vibration is easy to occur when the movable arm is large in mass or the air source is unstable, the welding quality of the aluminum alloy material is seriously influenced, and the stability and the reliability are poor. Therefore, a cylinder structure for an aluminum welding tongs is needed to solve the defects of the prior pressurizing cylinder in the actual use process. Disclosure of Invention The application provides a large thrust cylinder structure of a robot aluminum welding tongs, which has the advantages of compact structure, capability of achieving the aim of large-force pressurization through air chamber superposition, and capability of effectively locking a thrust shaft to prevent vibration, and is used for solving the problems that the existing pressurizing cylinder in the aluminum welding tongs is mainly composed of a large piston, a small piston and a high-pressure piston which are integrated in a cylinder body, and the large piston is used for driving the small piston, so that the pressure of a common air source is converted into local high pressure to be output outwards, but the whole structure of the cylinder is larger due to the pressurizing mode, the pressurizing coefficient is lower, the using parameters of the aluminum welding tongs under the condition of large pressure are difficult to meet, the application range of the aluminum welding tongs is greatly limited, meanwhile, the aluminum welding tongs have strict requirements on the overall stability of the aluminum welding tongs when welding operation is carried out, and the pressurizing cylinder on the existing aluminum welding tongs is locked and stopped only by virtue of air pressure, so that the phenomenon of vibration is very easy to occur when the movable arm quality is large or the air source is unstable, and the problem of the welding quality of aluminum alloy materials is seriously influenced.
