Description

TECHNICAL FIELD

[0002] The blind hole part refers to the part with blind hole characteristics in structure, and the blind hole is a machining method for forming a hole without complete penetration in the workpiece. The hole is characterized by starting machining from one side of the workpiece but not penetrating to the other side. The blind hole part is widely used or applied in various industrial machining and manufacturing fields, such as machining and manufacturing, instruments and meters, semiconductor devices, optical elements, watches and jewelry, medical devices, automobile manufacturing, aerospace, and electronic device manufacturing. The blind hole in the blind hole part can have various shapes, such as circular, square, oval, and irregular shapes. The blind hole can be formed by various machining methods, including drilling, milling, turning, etc. Drilling is the most commonly used method. The blind hole part plays an important role in practical applications, such as fixing bolts, damping, sealing, and realizing interlayer connection of circuit boards. The blind hole part hanger is a device specially designed for processing blind hole parts, which can make the blind hole part more conveniently suspended, fixed, and moved during processes such as electroplating and anodizing.

[0003] To this end, Chinese patent number CN212451687U discloses an anodizing hanger for blind hole parts. The hanger includes a main frame and a movable frame. The movable frame is connected to the main frame in the vertical direction. Each side of the movable frame is provided with multiple sets of turnover assemblies. Each turnover assembly includes a support. A plurality of fixing frames are arranged on the support at intervals. Two connecting rods are symmetrically arranged at the ends of the support. One end of each connecting rod is hingedly connected to the movable frame. The other end of each connecting rod extends outward from the main frame. A waist-shaped hole is formed in the end of each connecting rod away from the movable frame. A limiting rod is arranged on the main frame and cooperates with the waist-shaped hole. When the movable frame is at the lower limit of the stroke, the blind hole openings of the blind hole parts on the fixing frames are inclined upward. When the movable frame is at the upper limit of the stroke, the blind hole openings of the blind hole parts on the fixing frames are inclined downward. The utility model sets the movable frame on the main frame. The fixing frames are inclined upward or downward by the upward or downward sliding of the movable frame. This facilitates the disassembly and assembly of the blind hole parts and the discharge of air from the blind holes when the blind hole parts are in the electrolyte.
