Description

a marking tool

technical field

The utility model belongs to the technical field of part cutting and processing auxiliary tools, in particular to a marking tool.

Background technique

Usually, in the cutting operation of disk parts, it is necessary to form a scribe line on the surface of the part in advance, cut the part along the scribe line, and accurately determine the size of the part. At present, the scribing methods on the market are mainly divided into two categories: one is measuring and scribing, using measuring tools such as tape measure, calipers, etc. to measure, and then using scribing tools to scribble, usually only straight lines can be drawn, and the operation is complicated; the other The first class is to use a special scribing tool to scribble, and combine the measuring tool and the scribing tool to complete the scribing operations such as straight lines and curves. These two types of scribing methods are difficult to meet the more precise dimensional requirements on complex surfaces, and the sizing operation of different lengths requires a complicated adjustment process for the tooling, which is time-consuming and laborious.

Patent CN206140475U discloses a marking tool, including a positioning bearing, a supporting body, a sliding body, a scale, a pressing block and a marking screw. The locating bearing is rotatable along the central axis and is installed on the left end of the supporting main body and is located below the supporting main body, and the pressing block is installed above the supporting main body; the scale is fixed on the sliding main body, and the marking screw is fixed on the left end of the sliding main body. The pressing blocks are distributed on the upper side of the scale and vertical to the scale. There are 2 pressing blocks in total. When the supporting body is aligned with the left side of the sliding body, the left end of the left pressing block is located at the zero mark line of the scale; There is a wing bolt in the center of the block. Although the scribing tool described in this patent solves the problem of scribing lines on complex curved surfaces, the structure of this tooling is complicated, and the operation is cumbersome and time-consuming in the process of scribing and positioning.
