[0001] This utility model relates to the field of precision mold micro-hole processing technology, and in particular to a device for processing micro-holes in a charger precision mold. Background Technology

[0002] In today's booming consumer electronics industry, chargers, as an indispensable accessory for various smart devices, face higher requirements in terms of performance and size. To meet the market's demand for miniaturized, high-performance chargers, the manufacturing precision of charger molds has become crucial, especially the micro-hole processing on the molds, the quality of which directly affects the internal structural layout, heat dissipation performance, and electrical connection reliability of the charger.

[0003] Existing mold clamping methods mostly use traditional fixtures, which are difficult to accurately adapt to molds of different shapes and sizes. The clamping process is cumbersome, which affects the efficiency of opening holes. At the same time, the chip removal problem during the processing has not been effectively solved. Chip accumulation can not only scratch the mold surface, but may also damage the processing tools, increasing production costs and processing cycle. Utility Model Content

[0004] The purpose of this invention is to provide a micro-hole processing device for precision molds of chargers, which solves the problems of existing fixtures being unable to accurately adapt to molds of different shapes and sizes, having a cumbersome clamping process, affecting hole opening efficiency, and having chip accumulation affecting quality.

[0005] To achieve the above objectives, this utility model provides a micro-hole processing device for a precision mold of a charger, including a base and an auxiliary mechanism. Support legs are fixedly installed at the bottom of the base, and several support legs are installed. A worktable is fixedly installed on the upper surface of the base. The worktable is made of marble, and a processing groove is formed on the upper surface of the worktable. The auxiliary mechanism is located on one side of the processing groove. The auxiliary mechanism includes an opening, a sliding groove, and a clamping plate. An opening is symmetrically formed on one side of the processing groove. Sliding grooves are formed on the inner walls of both sides of the processing groove. The opening and the sliding groove are located on the same side, and the sliding groove is formed on one side of the opening. A clamping plate is movably arranged inside the sliding groove. A clamping plate is movably arranged inside the clamping plate. A magnetic block is embedded inside the clamping plate, and a magnetic plate is embedded inside the clamping plate. The magnetic plate and the magnetic block attract each other.

[0006] The inner sides of the first clamping plate and the second clamping plate are provided with arc-shaped grooves, and rubber pads are fitted inside the arc-shaped grooves.

[0007] The upper surface of the processing groove has a discharge port at both ends, and the discharge port is inclined downward and outward through the worktable to form a discharge port.

[0008] The workbench has support frames fixedly connected to both ends on its outer side, a crossbeam fixedly connected to the top of the support frame, and a sliding groove at the bottom of the crossbeam.

[0009] The slide groove has a limiting groove at one end, a lead screw is movably installed inside the limiting groove, and a drive motor is installed at the end of the lead screw away from the limiting groove.

[0010] The lead screw is movably mounted above a sliding block, and an electric push rod is fixedly mounted at the bottom of the sliding block. A horizontal plate is fixedly connected to the bottom of the electric push rod, and a second drive motor is fixedly mounted at the center of the bottom of the horizontal plate. A machining drill is connected to the output end of the second drive motor, and a nozzle is mounted above the horizontal plate. The nozzle is inclined inward and has several nozzles.

[0011] This invention uses a magnetic block embedded in clamping plate one and a magnetic plate embedded in clamping plate two. The two attract each other, firmly fixing the precision mold of the charger to the worktable. This ensures that the workpiece will not shift due to vibration or cutting force during micro-hole processing, thus guaranteeing the precision of micro-hole processing. At the same time, the arc-shaped grooves on the inner sides of clamping plates one and two fit the rubber pads, which can adapt to different mold surfaces, enhancing the adaptability of clamping and avoiding damage to the mold surface, effectively guaranteeing processing accuracy and quality. Through the discharge ports at both ends of the upper surface of the processing groove, combined with the outwardly inclined discharge port that penetrates through the worktable, a large number of tiny chips are generated during the micro-hole processing of the precision mold of the charger. If they are not discharged in time, the chips can easily accumulate in the processing area, not only affecting the processing accuracy but also potentially scratching the mold surface. Several inwardly inclined nozzles above the horizontal plate can spray coolant or high-pressure gas to further assist in chip removal. The chips slide quickly through the discharge port to the discharge port and are discharged, keeping the processing area clean, reducing the interference of chips on processing quality, and thus improving processing efficiency and mold processing quality.
