A countersink tool with quick adjustment and positioning

Abstract

The invention relates to the field of machining knife tools and discloses a novel countersink tool. The novel countersink tool comprises knife-containing blocks, knife tools used for machining are removably mounted on the knife-containing blocks correspondingly, and the knife-containing blocks are removably mounted on a main drilling shaft and rotate with the main drilling shaft. Each knife-containing block is designed in a briefs shape, a knife-containing block installing hole is formed in the central position of each knife-containing block, the knife-containing blocks are mounted on the main drilling shaft through the knife-containing block installing holes, two knife tool installing holes are formed in the two ends of each knife-containing block symmetrically, and knife tools are mounted in the knife-containing blocks through the knife tool installing holes correspondingly. Installation and operation are easy, maintenance, dismounting and assembly are convenient, cost is low, universality is good, and the labor strength of a worker is greatly reduced.

Description

technical field [0001] The invention relates to the field of processing tools, in particular to a countersinking tool which can be quickly adjusted and positioned. Background technique [0002] my country is a big manufacturing country. Every day, a lot of steel is processed into products, some of which are pipes. Pipes are widely used in electric power, chemical industry and other industries in the process of industrialization in our country. In the process of pipe processing, it is often necessary to draw out In order to facilitate the welding of the lead-out pipe, the counterbore is usually drilled at the same time. The counterbore is generally processed with a countersink. Because the pipe is used in a wide range of places, there are many specifications of the pipe and the diameter of the hole. This has certain requirements for processing tools. [0003] Existing countersinking tools usually use integral tooling, which has many deficiencies in actual production engineerin...

AI Technical Summary

Problems solved by technology

[0003] Existing countersinking tools usually use integral tooling, which has many deficiencies in actual production engineering, such as: 1. The entire tool is made of high-alloy steel. Once a part is damaged, the entire tool needs to be replaced, which is costly ;2. Due to the diversity of processed products, it is necessary to process tube holes of different specifications. Each hole diameter requires a set of tooling. The tool has no versatility and the processing range is single. Increase the labor intensity of employees and affect the production schedule

3. After the overall tooling of the tool, the chip removal space at the edge of the countersinking tool is small, and the resistance is large, which is easy to damage the tool

4. The edge of the countersinking knife is in a harsh working environment, and the blade is easily damaged. Generally, the countersinking knife is not equipped with corresponding grinding tools. It is inconvenient to repair and needs to be returned to the processing factory for maintenance. The maintenance cost is high and affects the production progress.
