Countersink tool used for processing end face ring groove and manufacturing method thereof

Abstract

The invention relates to a countersink tool used for processing an end face circular groove and a manufacturing method of the countersink tool used for processing an end face circular groove. The countersink tool comprises a countersink tool rod, wherein countersink tool rod is formed by a drill rod of which the front end is a drilling end; the drilling end of the drill rod has the drilling diameter which is the same as the outer diameter of a corresponding ring groove to be processed; the drilling end of the drill rod is provided with a groove which is provided with a forward groove opening and is coaxial with the drill rod; the groove has the diameter which is the same as the inner diameter of the corresponding ring groove to be processed; a cutting edge used for processing the ring groove is formed by the drill rod part between the wall of the groove and the peripheral surface of the drilling end; the groove is internally and coaxially fixed with a positioning shaft through a fixed connecting structure; a gap is formed between the peripheral surface of the positioning shaft and the wall of the groove; and the front end of the positioning shaft is provided with a workpiece positioning section used for being coaxially inserted with the central hole of a corresponding workpiece to be processed. With the adoption of the countersink tool used for processing the end face ring groove and the manufacturing method of the countersink tool, the existing drill rod is processed into the countersink tool rod, so that the manufacturing time of the countersink tool is reduced.

Description

technical field [0001] The invention relates to a countersinking tool for machining end face ring grooves and a manufacturing method thereof. Background technique [0002] When machining the end face ring groove of some parts (such as the sealing groove for installing the sealing ring), because the inner and outer diameters of the ring groove are relatively small, the size of the countersinking tool required is small and it is not easy to manufacture. The production of the knife takes a long time and the production cost is high. Especially in the research and development process of new products, sometimes new countersinks are urgently needed due to research and development needs, but due to the long manufacturing cycle of countersinks, the delay will affect the entire research and development process of new products, and increase the research and development of the entire research and development process. cost. SUMMARY OF THE INVENTION [0003] The purpose of the present...

Problems solved by technology

[0002] When machining the end surface ring grooves of some parts (for example, the seal grooves for installing sealing rings), since the inner diameter and outer diameter of the ring grooves are relatively small, the size of the countersinking tool required is small and difficult to manufacture. The existing countersinking The manufacture of knives takes a long time and is expensive to manufacture

Especially in the development process of new products, sometimes new countersinking tools are urgently needed due to research and development needs, but due to the long manufacturing cycle of countersinking tools, the delay affects the entire new product development process and increases the research and development process of the entire research and development process. cost
