Multi-line laser marking instrument with processing and mounting precision easy to ensure

Abstract

The invention relates to a multi-line laser marking instrument which comprises a main body, wherein the main body comprises a vertical laser seat, and four concave laser mounting grooves are formed in the top end of the vertical laser seat and are sequentially distributed at intervals of 90 degrees; a groove cover is arranged above the vertical laser seat, and V-shaped grooves or trapezoid-shaped grooves opposite to the laser mounting grooves are formed in the groove cover; a vertical laser of the marking instrument is arranged between the laser mounting grooves and the V-shaped grooves or trapezoid-shaped grooves. The vertical laser seat and the groove cover are two components and can be respectively formed at one step through moulds during production, namely the four concave laser mounting grooves sequentially distributed at intervals of 90 degrees in the vertical laser seat and the groove cover which is provided with the V-shaped grooves or trapezoid-shaped grooves opposite to the laser mounting grooves can be respectively formed at one step through the moulds during production. Therefore, the production process is comparatively simple and convenient, the precision is easily ensured, and the cost is low.

Description

[0001] This application is a divisional application, the application number of the original application: 2011101096328, the name of the invention: multi-line laser marking instrument, and the application date: 2011-4-29. technical field [0002] The invention relates to a multi-line laser marking instrument. Background technique [0003] The body of the existing multi-line laser marking instrument includes: a vertical laser base and a horizontal laser set on one side of the middle of the vertical laser base in the height direction, and four groups of vertical lasers that can emit vertical lines are evenly distributed on the top of the vertical laser base , the angle between adjacent vertical lines is 90°, which provides convenience for actual observation, especially benchmark calibration in complex construction environments, laying of pipe network projects and engineering acceptance. [0004] The deficiencies of the above-mentioned marking instrument in the prior art are: ...

AI Technical Summary

Problems solved by technology

The counterweight is generally made of metal, resulting in higher production costs, and the corresponding installation and debugging steps are more cumbersome

[0007] 3) The body of the multi-line laser marking instrument is set on the base through a rotary seat. There is a damping ring between the rotary seat and the base. The assembly is complicated, and once the damping ring fails, the fine-tuning function cannot be realized. , which is less reliable
