Embodiment Construction
[0031] The following will combine Figure 1 ~ Figure 3 A high-precision positioning pin hole matching drilling tool of the present invention and its application method are further described in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] Such as figure 1 As shown, the present invention discloses a high-precision positioning pin hole matching drilling tool, including a base plate 2, an installation body 3, an adjustment block 5, a drill sleeve (hinge sleeve) 8, mounting screws 4, 6, 9, adjustment screws 7, 10, 11, 12 and the pin holes 13 required to be punched. Such as figure 2 As shown, there is a through hole on the adjusting block, which is used to observe the product status and install the drill sleeve (reaming sleeve) 8 when the pin hole is matched and punched. Such as image 3 As shown, the drill sleeve and reaming sleeve are made of 2Cr13 sta...

The invention discloses a high-precision positioning pin hole matching drilling tool and a using method. The tool comprises a bottom plate, a mounting body, an adjusting block, a drill sleeve, a hingesleeve, adjusting screws and mounting screws, wherein the hinge sleeve and the drill sleeve are machined to be consistent in appearance, and it is guaranteed that the positioning precision is not changed after interchange. During use, a product needs to be subjected to pin hole matching drilling is placed between the mounting body and the bottom plate, and the position of the product is adjustedand fixed through the adjusting screws above the bottom plate and on the two sides of the mounting body; the adjusting block and the drill sleeve are arranged, the position precision of an upper end pin hole and a lower end pin hole is guaranteed through the adjusting screws of the adjusting block and the drill sleeve respectively, and the adjusting body and the drill sleeve are locked through fixing screws after an accurate measurement result is met; and upper and lower end positioning pin hole bottom holes are subjected to matching drilling, only one screw for adjusting the drill sleeve is loosened, the hinge sleeve is replaced, the adjusting screw is locked again, and reaming is carried out. According to the tool, the structural form is simple, the operation is easy and convenient, theposition precision of pin hole matching drilling is guaranteed, and a new matching drilling scheme is provided for pin holes which cannot be machined through a machine tool.
Description
technical field [0001] The invention relates to a pin-hole drilling tool, in particular to a high-precision positioning pin-hole drilling tool that cannot be machined with an extra bed and a use method thereof. Background technique [0002] The main tasks of the Fengyun series satellites include remote sensing monitoring of global precipitation, global cloud liquid water content, global vegetation, etc., and the antenna deployment mechanism is an important payload of the Fengyun series satellites. The installation accuracy of the antenna directly affects the quality of satellite remote sensing images. The realization of the satellite function. [0003] The perpendicularity between the two positioning pin holes on the active arm of the antenna deployment mechanism and the antenna is required to be ±0.05°, and the distance tolerance between the positioning pin holes on the upper end and the antenna is ±0.1mm. However, the connecting arm of the product is a hinge structure, wh...
