Eccentric cam of screw tap relief grinding machine

Abstract

The invention discloses an eccentric cam of a screw tap relief grinding machine. The eccentric cam comprises a cam and holes, wherein the cam is made by a cylindrical metal block; the rounded corners of the front round face and the rear round face of the cam are respectively cut into chamfers of 45 degrees; a round through hole is drilled in the middle of the front round face of the cam; a rectangular through hole is also drilled in the middle of the front round face of the cam and above the round through hole; the rectangular through hole is communicated with the round through hole; the circumscribed circle of the cam has a circumscribed circle center, and the circle center of the round through hole is perpendicularly below the circumscribed circle center and deviates from the circumscribed circle center; the longitudinal center lines of the rectangular through hole in the left direction and the right direction are coincided with the longitudinal center lines of the cam in the left direction and the right direction; the linking lines of the two circle centers with the longitudinal center lines of the rectangular through hole in the left direction and the right direction are coincided; and the rectangular through hole is communicated with the round through hole to form the through hole of the eccentric cam.

Description

[0001] technical field [0002] The present invention relates to the eccentric cam of the screw tap relief grinder, specifically, the eccentric cam of the relief grinder which is used for sharpening the cutting edge of the screw tap, which is a tool used on a numerical control machine tool, and is another method for processing the tool of the machine tool, namely the screw tap. An important part of a new device. Background technique [0003] Usually, what must be used in machinery manufacturing and processing plants: one is the machine tool, and the other is the tools used on the machine tool. Both are indispensable. A good machine tool is like a CNC machine tool. The tools used are like taps, and the blade of the tap makes it sharp. To improve the quality of the tap, it is necessary to process and grind the tap, so that the blade of the tap is sharp, the quality of the tap is good, and the products produced are superior; and to achieve this goal, a relief grinder is need...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects of eccentric cam design error and unreasonable structure of common relief grinder, such as relief grinding misalignment, low precision, blade curling, etc., the present invention provides eccentric cam of tap relief grinder, eccentric cam of tap relief grinder, etc. The cam is an important part of the shovel grinder. The correct design and reasonable structure can make the shovel grinder run normally and regularly during work, thus ensuring the stable operation of the shovel grinder. Relief grinding in place
