Description

Technical Field

[0001] The utility model relates to a small insulating component drilling and milling device, which is mainly used in the field of high-temperature resistant small insulating component processing fixtures. Background Art

[0002] In order to make aerospace products adapt to various special environments, the insulation materials of supporting products are mostly made of high-temperature resistant composite materials PI (polyimide), and the processing of high-temperature resistant insulation parts can generally be done by injection molding. For special requirements of high-temperature resistant (400-500℃) insulation materials, injection molding cannot be used, and parts can only be produced by mechanical processing. Since the small insulation structure is designed with multiple small-diameter holes and step holes, external keys and reverse coaxial countersunk holes need to be processed on the outer circle of the parts, and the size and position tolerance range is small. The existing processing technology uses single-piece clamping, which requires repeated clamping to complete the process used, resulting in poor consistency in the position and coaxiality of small-diameter holes, as well as the symmetry of external keys and small-diameter holes, and low processing efficiency. When the number of single batches of production tasks is large, single-piece processing is not only inefficient, but also increases the labor intensity of operators, and the machine tool frequently changes tools, affecting the life of the machine tool. The overall processing efficiency has always been at a low level.

[0003] In order to solve the problems of poor consistency of existing processing size and position tolerance of small insulating parts, low processing efficiency and high labor intensity of operators, it is very necessary to explore a small insulating part drilling and milling device to improve production efficiency.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The utility model relates to a drilling and milling device for small insulating parts, which is mainly used in the field of high-temperature resistant small insulating parts processing fixtures, including a cylindrical clamping seat, a rectangular mounting seat, a positioning step through hole, a reverse countersunk hole, an open through slot, and a bolt; the top of the cylindrical clamping seat is integrally connected with the rectangular mounting seat, two rows of equidistant positioning step through holes are arranged on the top plane of the rectangular mounting seat, two rows of equidistant reverse countersunk holes are arranged on the bottom plane of the rectangular mounting seat, the reverse countersunk holes are coaxial with the positioning step through holes, an open through slot is arranged in the horizontal direction of the center of each row of holes, through holes are arranged at both ends of the two side surfaces of the rectangular mounting seat, and threaded through holes are arranged at both ends of the middle portion.

[0007] The number of positioning stepped through holes arranged in each row on the top plane of the rectangular mounting seat is 4, 8 in total, which are used for positioning and mounting small insulating parts.

[0008] The number of the reverse countersunk holes arranged in each row on the bottom plane of the rectangular mounting seat is 4, 8 in total, and is used for processing the countersunk holes at the right end of small insulating parts.

[0009] The two ends of the two side surfaces of the rectangular mounting seat are each provided with two through holes, for a total of four. The middle part of the rectangular mounting seat is provided with two threaded through holes coaxially with the side through holes, which are connected by bolts and used to clamp small insulating parts.
