Precise leveling surveying instrument for high-end equipment manufacturing

Abstract

The invention discloses a precise leveling surveying instrument for high-end equipment manufacturing. The precise leveling surveying instrument comprises a bracket main body, first bracket levers anda screw sleeve, wherein the inner wall of the bracket main body is fixedly connected with the screw sleeve; multiple first bracket levers are inserted into the bottom of the bracket main body; the outer walls of the first bracket levers are fixedly connected with fixed plectrum sliding blocks I; the inner walls of the first bracket levers are connected with second bracket levers in a sleeving manner; the first bracket levers and the second bracket levers are in clearance fit. According to the precise leveling surveying instrument disclosed by the invention, the surveying instrument is pressedthrough a groove formed in a bottom plate to reduce a clearance between a first clamping plate and a second clamping plate so as to slide inwards; the precise leveling surveying instrument is mountedfixedly and convenient to calibrate through a first compression spring between the first clamping plate and the second clamping plate; the surveying instrument can be quickly leveled by adjusting a fine adjustment knob, and the time is saved; secondary leveling is not required through left-right sliding of the clamping plates in the groove, so that the working efficiency is improved, and a surveying result is not affected.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping instruments, in particular to an accurate leveling surveying and mapping instrument for high-end equipment manufacturing. Background technique [0002] Protrusions are not allowed on the working surface of the surveying instrument, and its flatness shall meet the requirements in Table 6-10-54. The length of the working face is 150~200, 250~300, and the flatness deviation is <0.003<0.005. For the grinding and grinding working face, the flatness is verified by the zero-level knife-edge ruler whose size is not less than the length of the tested surface, and the light gap method is used for verification , this verification work should be carried out at several positions in the longitudinal, transverse and diagonal directions of the working face. The largest gap seen is the flatness deviation of the surface. When estimating the size of the gap, it can be compared with the standard...

Problems solved by technology

[0003] At present, the surveying and mapping devices on the market are basically leveling. Although there are many types and quantities of leveling surveying and mapping devices, the leveling and calibration of most leveling surveying and mapping devices before use is troublesome and time-consuming. Then the calibration is troublesome, and the bracket needs to be moved when the small displacement moves horizontally, and it needs to be leveled again, which will not only reduce the work efficiency but also affect the accuracy of the surveying and mapping results
