Embodiment Construction

[0009] The present invention will be described in further detail below. Drilling molds for machining fuse holes in one mold with multiple parts for shafts mainly integrate three innovative points: clamping with multiple pieces in one mold, fixed angle with spring pins, and stable support with wedges. This drilling mold has the function of clamping 4 products at one time, and can continue to expand the processing of multiple products according to the actual needs and the stroke of the machine table. The basic support 1 is used as an integral support for the entire drilling jig, and is used for positioning the outer cylindrical surface and the bottom surface of the product 15, and is also used for matching and connecting other components to achieve specific functions. The angular positioning pin 5 is used to locate the angular direction of the product, and cooperate with the positioning of the base support on the outer cylindrical surface and bottom surface of the product to rea...

Abstract

The invention belongs to the field of aviation machining process equipment, and discloses a shaft type one-jig multi-piece fuse hole machining drill jig. The drill jig mainly comprises a foundation support, an angular positioning pin, a wedge block and the like. The front end of the angular positioning pin is manufactured into a conical surface structure to be matched with a product notch; and an elastic structure is made to eliminate over-positioning. The wedge block moves forwards in a wedge groove and meanwhile generates Z-direction displacement so as to make contact with products to play a supporting role, and it is guaranteed that the products do not vibrate during drilling. The foundation support serves as an integral support of the whole drill jig, is used for positioning the outer cylindrical surfaces and the bottom surfaces of the products and is matched and connected with other elements to achieve specific functions. One-jig multi-piece clamping, elastic pin angle direction fixing and wedge block stable supporting of shaft products needing to be provided with small-size fuse holes are achieved. The purposes of accurate positioning, reliable supporting, reduction of tool changing frequency and improvement of machining efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of aviation machinery processing technology equipment, and is suitable for processing fuse holes of small-sized shaft products. A new set of drilling molds for processing multiple pieces of fuse holes with one mold for shafts, which can realize the processing of multiple pieces of products by one clamping. Background technique [0002] In aviation products, there are a large number of small-sized shaft parts for connection and positioning. Due to the high safety factor requirements in the aviation field, such products must have fuse holes for mechanical anti-loosening to improve reliability. According to the structure requirements of the product, the fuse holes are mostly small holes, which are not easy to guide the drill bit during processing and are easy to break when the drill bit is finely processed. This requires a special drilling jig to guide and protect the drill bit. [0003] The traditional special-purpos...
