Description

The omnidirectional mechanism of self leveling Laser Line Marker

Affiliated technical field

The utility model relates to a kind of omnidirectional mechanism of self leveling Laser Line Marker

Background technology

The self leveling Laser Line Marker is the laser device that level and vertical reference can be provided fast.Instrument has fast automatic Anping function.The principle of instrument self leveling is the omnidirectional mechanism that is fixed on the support by, the laser module is suspended in midair, and utilizing damping mechanism to make the laser module under the effect of gravity, remain on an equilibrium position, light that adjustment mode of laser group is sent on this equilibrium position or luminous point are to level or upright position.Therefore, when deflection appearred in the instrument placement, the laser module all can be got back to the equilibrium position under the effect of gravity and damping system, thereby realized providing fast level or vertical benchmark function.Self leveling Laser Line Marker and the most important index of self leveling Geoplane are setting accuracies, the deviation between light that the laser module sent when just instrument departed from horizontal level or luminous point and level or the upright position.At present the setting accuracy of self leveling Laser Line Marker and self leveling Geoplane require most of at 10m deviation 1mm between the 10m deviation 3mm, in influencing instrument self leveling precision all multifactor, omnidirectional mechanism is one of key factor.Omnidirectional mechanism is usually by bearing, bearing seat, rotating shaft and be used for the part adjusted in the gap etc. and form.The adjustment of omnidirectional mechanism gap is loose excessively, will cause laser module deviation of gravity center in motion process, thereby influences the self leveling precision; Tension is adjusted in the omnidirectional mechanism gap, will cause the resistance of motion of laser module too big, thereby influence the self leveling precision; If the right alignment between the bearing of omnidirectional mechanism, bearing seat and the rotating shaft is bad, the size of the resistance of motion that will cause the laser module is along with movement angle changes, thereby influences the self leveling precision; If the bearing seat of omnidirectional mechanism and rotating shaft insufficient strength, omnidirectional mechanism can produce distortion slowly under external force, cause the center of gravity of laser module to change, also can influence the self leveling precision.The omnidirectional mechanism that existing self leveling Laser Line Marker and self leveling Geoplane adopt, form by three rings of interior ring, middle ring, outer shroud mostly, four groups of independent rotation structures are housed, two groups of rotating mechanisms are formed the rotating shaft of a direction, thereby cause the right alignment between rotating shaft, bearing and the bearing seat to be difficult to guarantee, assembling, debugging complexity, processing technology complexity, defectives such as omnidirectional mechanism intensity difference, the efficient and the product quality of influence processing, assembling.

Summary of the invention

For overcoming the omnidirectional mechanism deficiency of existing self leveling Laser Line Marker, the utility model provides a kind of omnidirectional mechanism of self leveling Laser Line Marker, and this mechanism is made up of the rotating mechanism that two quadratures are installed, and adopts through rotating shaft.This mechanism's processing technology is simple, can guarantee the right alignment of rotating shaft, bearing, bearing seat, structural strength height, not yielding, and the mechanism gap is easy to adjust, can effectively simplify processing, assembly technology, improve production efficiency and product quality.

The technical solution of the utility model is: omnidirectional mechanism is made up of upper bracket, lower carriage, connection Crux and two groups of through incorporate rotating mechanisms.Lower carriage and laser module fuse, and are connected to by rotating shaft to connect on the Crux; Upper bracket is fixed on the instrument support, is connected to by rotating shaft equally to connect on the Crux; Two rotating shaft quadratures are installed, and stagger up and down, avoid interfering.Each through incorporate rotating mechanism is made up of two bearings, two bearing seats, two accent crack trim rings, two spacer rings, two holding screws and a rotating shaft.Two bearings are installed in respectively in the bearing seat on upper bracket or the lower carriage, and rotating shaft is passed two bearings, two spacer rings and is connected Crux, and are screwed and are connecting on the Crux.Two spacer rings fill up respectively and are connecting between Crux and two bearings, and spacer ring withstands the inner ring of bearing, the surface of contact outer diameter A of spacer ring and bearing≤bearing inner race external diameter B; Two outer rings of transferring the crack trim ring to push down bearing respectively from two ends, transfer the surface of contact internal diameter C 〉=bearing outer ring inside diameter D of crack trim ring and bearing, transfer the surface of contact external diameter E≤bearing outer ring external diameter F of crack trim ring and bearing, adjust to transfer the gap that the crack trim ring just can the easy adjustment omnidirectional mechanism and the axial location of support, make it to meet the requirements.Because unidirectional two bearing seats processing is on same support, its right alignment can guarantee, and physical strength is higher; Rotating shaft is a through installation, and physical strength and right alignment are also guaranteed.

The beneficial effects of the utility model at first are that right alignment is good, because unidirectional two bearing seats processing is on same support, its right alignment is fine, the fit dimension of bearing seat and bearing is processed easily, adopts a through rotating shaft simultaneously, and the right alignment after the assembling guarantees easily.Next physical strength height, because bearing seat and support one, rotating shaft is through, its physical strength is higher.They are three years old, assembling, debugging are simply, because right alignment is good, physical strength is high, avoided the right alignment debugging link of omnidirectional mechanism in the past in the assembling, only needing to adjust the crack trim ring adjusts the gap of omnidirectional mechanism and axial location and meets the requirements and get final product, simplify assembling, testing and measuring technology greatly, improved and debug efficient, guaranteed product quality.
