Rotary body positioning device and scribing method

Abstract

The invention discloses a rotary body positioning device and a scribing method. The rotary body positioning device comprises a first fixing block and a second fixing block which are used for fixing a rotary body. A first square with the diameter of the rotary body as the side length is marked on the first fixing block, and a second square with the diameter of the rotary body as the side length is marked on the second fixing block. One end of the rotary body is welded with the first square, and the other end of the rotary body is welded with the second square; the edge of one end of the revolved body is tangent to the first square, and the edge of the other end of the revolved body is tangent to the second square; the first square is parallel to the second square. The rotary body can be fixed through the rotary body positioning device, the problem that the rotary body is prone to rolling is solved, and scribing operation is facilitated; after the rotary body is positioned, the angle, needing to be marked, of the positioned rotary body is converted into the height; and according to the converted height, scribing is performed on the positioned rotary body through a height gauge. The method can be used for quickly aligning and scribing, simplifying the measurement process and realizing the aim of quickly scribing.

Description

technical field [0001] The invention relates to the technical field of revolving body positioning and marking, in particular to a revolving body positioning device and a marking method. Background technique [0002] Rotary products need to determine the reference line by scribing during the processing process. The usual method is to use a V-shaped iron on the scribing platform to align, convert the angle into an arc length, measure the surface of the rotator, and then scribing. In addition, the indexing plate can also be used for scribing. However, in recent years, with the increasing variety of products produced, the product structure has become more and more complex, and more and more rotary products with small diameter and large aspect ratio have been produced. The rotary body with a diameter ratio has a large error and low precision when marking the line, and when the diameter of the rotary body is smaller than the minimum limit for the use of the graduated scale, the g...
