Turning tool for improving quality of surface of flange end face sealing groove

Abstract

The invention provides a turning tool for improving the quality of the surface of a flange end face sealing groove. A grooving tool is provided with a main cutting edge, tool nose smoothing edges and auxiliary cutting edges. The main cutting edge, the tool nose smoothers and the auxiliary cutting edges are integrally formed in a grinding mode. According to the main cutting edge of the grooving tool, an original linear common end face grooving turning tool main cutting edge is improved into a concave circular-arc-shaped main cutting edge. According to the two tool nose smoothers, original common end face grooving turning tool nose circular arc radiuses are improved into tool noses with smoothing edges, the surface quality is improved by one time while the same feeding can be ensured. According to the auxiliary cutting edges on the two sides of the grooving tool, the width of an original common end face grooving turning tool is improved to be half of the width of a sealing groove, chip removing is easy, and gear marks are reduced. The turning tool has certain universality and is suitable for machining flange type parts, the machining deformation is small, the surface quality is high, the production period is greatly shortened, the production cost is reduced, and therefore the turning tool can be applied and popularized.

Description

technical field [0001] The invention relates to the technical field of parts turning, in particular to a turning tool for improving the surface quality of end face grooves of flange parts. Background technique [0002] In the field of aerospace, flange parts are used as the interface parts of the storage tanks and pipelines of the launch vehicle, and play the role of connection and sealing. The surface processing quality of the flange sealing groove will directly affect the sealing effect of the flange, and then affect the quality and reliability of the product. With the new generation of carrier models, the surface quality of the flange sealing groove is getting higher and higher, and the demand for high-quality processing of the sealing groove is becoming more and more urgent. Since the flange parts are mostly weak rigid parts, the relative rigidity is low and the processing technology is poor. Especially when turning the flange end face groove, because the groove tool i...

Problems solved by technology

[0005] 2. Ordinary CNC grooving blade

[0006] Through the above analysis, the current end face groove turning tools are all linear cutting, the cutting force is large, the tool vibration is serious, and it is easy to form vibration lines and tool marks on the machined surface

Affects the surface finish of the end face groove, making it difficult to control the quality of the machined surface
