Sliding rail type automatic lineation ruler and method

Abstract

The invention relates to a sliding rail type automatic lineation ruler and method. The sliding rail type automatic lineation ruler is provided with a component I, a component II, a positioning sliding block, a lineation sliding block, a cross-shaped sliding bar, a spring, two lineation correcting sheets and a configuration bar. The component I, the component II, the positioning sliding block and the lineation sliding block are all provided with configuration bar assembly holes and cross-shaped sliding bar assembly holes. The component I is provided with a spring groove. The lineation sliding block is provided with a pen hole into which a lineation pen is inserted. One end the cross-shaped sliding bar penetrates through the lineation sliding block and the component I to be connected with a knob I, and the other end of the cross-shaped sliding bar penetrates through the positioning sliding block and the component II. The cross-shaped sliding bar is sleeved with the spring, one end of the spring is installed in the spring groove in the component I, and the other end of the spring makes contact with the lineation sliding block. The two lineation correcting sheets are symmetrically installed on the component I and the positioning sliding block respectively. The component I, the lineation sliding block, the positioning sliding block and the component II are connected together through the configuration bar. The sliding rail type automatic lineation ruler increases the success rate of lineation and improves the accuracy of lineation.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a slide rail type automatic marking tool, in particular to a slide rail type automatic marking ruler and a marking method for drawing straight lines on templates and flat parts. Background technique [0002] In the aircraft manufacturing industry, the templates and tooling used for parts processing and inspection have been realized through digital processing methods, but it is still unavoidable to draw straight lines on the templates, parts, including tooling. [0003] Especially when it is a long straight line, after determining the start and end points of the line, there is often a radian when scribing, resulting in inaccurate scribing. In addition to the lack of professional scribing tools, the main reason is that the scribing workers operate with both hands. After the traditional steel ruler calibrates the starting point and end point of the marking, it is necessary to pres...

Problems solved by technology

[0003] Especially when it is a long straight line, after determining the start and end points of the line, there is often a radian when scribing, resulting in inaccurate scribing. In addition to the lack of professional scribing tools, the main reason is that the scribing workers operate with both hands. After the traditional steel ruler calibrates the starting point and end point of the marking, it is necessary to press and fix the steel ruler with one hand, and draw the line with the other hand. The hand-fixed steel ruler is extremely unstable. When the marking is halfway through, it is often found that the end of the steel ruler does not match the end of the marking. In this case, re-calibrate the end of the steel ruler to coincide with the end of the marking, and continue marking. caused a dashed error

It cannot meet the design requirements, and in serious cases, it will lead to the scrapping of the whole part and affect the quality of aircraft products

[0004] The way to reduce this kind of error is to operate two workers at the same time, one worker presses the steel ruler with both hands, and the other worker draws the line, which wastes manpower and affects production efficiency
