Drill bit machining and post-treatment device for electric tool

Abstract

The invention relates to a drill bit machining and post-treatment device for an electric tool. The drill bit machining and post-treatment device comprises an inner storage box, an outer storage box and a pair of screening plates. A rectangular through hole allowing drill bits to pass is formed in the upper end of the outer storage box, and an opening allowing the inner storage box to be embedded is formed in the side end of the outer storage box; the pair of screening plates are mounted at the upper end of the outer storage box; a pair of reverse double-thread movable lead screws are arrangedin the positions, located at the two ends of the rectangular through holes, of the upper end of the outer storage box; lead screw nuts matched with the movable lead screws are arranged on the two sides of the bottom ends of the screening plates correspondingly; two openings are formed in the middles of the adjacent ends of the two screening plates; and the openings in the two screening plates jointly form a gap allowing the drill bits to pass. The drill bit machining and post-treatment device for the electric tool has the advantages that the inner storage box, the outer storage box and the screening plates are adopted to be matched, and thus the situation that the drill bits of the two different diameters are stored in the same storage box is avoided; and the spacing between the two screening plates is adjusted through matching of the movable lead screws and the lead screw nuts, and thus adjustment is more convenient.

Description

technical field [0001] The invention relates to the field of electric tool manufacturing, in particular to a post-processing device for drill bits used in electric tools. Background technique [0002] In the 1960s, with the development of battery manufacturing technology, battery-type electric tools without power cords using nickel-cadmium batteries as power sources appeared. But at that time, due to the high price, the development was slow. By the mid-to-late 1970s, due to the reduction in battery prices and shortened charging time, this type of power tool was widely used in Europe, America, and Japan. Electric tools were originally made of cast iron, and then aluminum alloy was used as the casing. In the 1960s, thermoplastic engineering plastics were applied to electric tools, and realized double insulation of electric tools, ensuring the safety of electric tools. Due to the development of electronic technology, electronic speed control electric tools also appeared in t...

Problems solved by technology

[0003] For the drill bit, one of the parts of the electric tool, in the process of batch processing, due to the large number of processing, in the process of storage, it is usually used to place the processed drill bit in the temporary storage box , and the drill bits produced in the workshop, for the same type of drill bits, there will also be differences in thickness. There are two types of drill bits in the box. At this time, the staff needs to screen again, which increases their workload.
