Automatic welding rack and workpiece loading and unloading method

Abstract

The invention relates to an automatic welding rack and a workpiece loading and unloading method. The automatic welding rack comprises a base (10), a workpiece table (20), a support (30), a rotary mechanism (40), a lifting mechanism (50), a workpiece loading mechanism (60), a welding mechanism (70) and a workpiece unloading mechanism (80), wherein the lower portion of the support (30) is fixed on the base (10); the middle of the support (30) bears the workpiece table (20); the top of the support (30) is connected with the welding mechanism (70); the workpiece table (20) is provided with the workpiece loading mechanism (60) and the workpiece unloading mechanism (80); the rotary mechanism (40) is fixed on the base (10) and can rotate; the lifting mechanism (50) controls a lifting rod to move in the up-down direction along a sleeve arranged on a rotary table; and the welding mechanism (70) is fixed above the workpiece table (20). Welding precision and welding efficiency are guaranteed effectively, modification cost is reduced, workpieces are loaded simply, welding automation is high, a process is controllable, the workpieces are unloaded automatically, and the speed is adjsutable.

Description

technical field [0001] The invention relates to the technical field of production auxiliary equipment, in particular to an automatic welding bench and a method for loading and unloading parts to be welded. Background technique [0002] Welding parts are one of the auto parts. More and more parts in the car are connected by welding. The quality of welding has become one of the key factors affecting the overall performance of the car. The improvement of welding speed and efficiency has also become the key to the improvement of the efficiency of car production. The key. [0003] At present, there are two main welding auxiliary methods: one is the welding method that is still widely used in small and medium-sized enterprises by hand with simple fixing machines. The characteristics of this method are that the initial investment is very small, the fixture design is simple, but the welding quality is not good. Stable, the welding process cannot be standardized, and the welding acc...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic welding station for small and medium-sized enterprises. The cost of using robots to replace manual welding is too high, and the use of manual methods to achieve welding, loading and unloading is faced with problems such as unstable quality and low efficiency. Frame and application of its loading and unloading method, its loading is simple to operate and automatic unloading, the welding process is automatically controllable, so it can improve welding efficiency; it reduces the dependence of welding quality on workers' skills, ensures welding accuracy, and improves welding efficiency. The degree of automation and standardization, and try to reduce the initial investment cost of small and medium-sized enterprises and the increase in later use and maintenance costs
