Description

Technical Field

[0001] The present invention relates to the technical field of automatic assembly of electric tools, and in particular to a front cover component assembly system. Background Art

[0002] Handheld power tools are machines that perform mechanical functions driven by electric motors or electromagnets. They can be categorized by their intended use into metal cutting, sanding, and assembly. Angle grinders, also known as grinding machines or disc grinders, are a type of sanding machine and are primarily used for cutting, grinding, and brushing metal and stone.

[0003] The main components of an angle grinder include the spindle, dust seal, head shell, housing, stator, rotor, transmission gear, controller, and shaft. Due to the wide variety of components and the complex connections between them, there are currently no fully automated angle grinder assembly lines in the industry. Instead, a semi-automatic, semi-manual assembly process is often used to improve assembly efficiency.

[0004] The front cover assembly is to install the main shaft assembly and the gear in sequence in the inner cavity of the front cover, and the assembly is achieved by press fitting, and the main shaft assembly is a main shaft equipped with a dust ring.

[0005] The front cover assembly is mainly used for subsequent assembly with the angle grinder head shell to realize the function of the angle grinder. Because the core components of the front cover assembly, the front cover, the spindle assembly and the gears all have different appearances, and due to their special structure and assembly method, there has been no good assembly equipment in the current automated assembly process of angle grinders. The more common method is to manually pick up the materials and then assemble them manually, which is not only laborious, but also has a low pass rate for the finished product and is extremely inefficient. Alternatively, the material is picked up on an assembly line, and then manually placed under the designated riveting tool for press-fitting. After the press-fitting is completed, the material is collected and the above process is repeated.

[0006] It can be found that the above traditional solution cannot achieve fully automated loading, pressing and unloading of the front cover, spindle assembly and gears, which will seriously restrict the efficiency of angle grinder assembly and increase the cost of manufacturers.

[0007] Therefore, a new technical solution is urgently needed to solve the above technical problems. Summary of the Invention
