[0002] The manufacturing of distribution switch control equipment refers to the manufacture of electrical appliances for connecting and disconnecting or protecting circuits for voltages exceeding 1000V, such as those generally used in distribution systems, and distribution switch control equipment and its parts for voltages not exceeding 1000V, such as those used in housing, industrial equipment or household appliances. The main raw materials for the distribution switch control equipment manufacturing industry are steel, copper, aluminum and insulating materials, etc. The procurement cost of the above raw materials accounts for about 50% of the total product cost. The downstream application areas mainly include power distribution systems in industrial, commercial and civil buildings such as factories, shopping malls and residences, and supporting facilities of power grids. Metal plates are usually required in the manufacturing process of distribution switch control equipment, and metal plates need to be processed before they can be assembled and applied to distribution switch control equipment. Drilling is one of the processing steps.

[0003] At present, when drilling holes in metal plates with drilling equipment in the prior art, since the thickness of the plates to be drilled is not easy to determine, the plates need to be fixed first to avoid positional displacement during the drilling process, and then the drilling equipment is lowered to the surface of the plates to drill holes. Therefore, clamping and hole turning need to be performed in steps, which not only leads to low processing efficiency, but also increases the number of operating steps for the staff.

[0004] Based on this, the present invention designs a metal plate drilling device for manufacturing distribution switch control equipment to solve the above-mentioned problems. Summary of the invention
