The capacitive grating ruler comprises a capacitive grating ruler and the capacitive grating ruler body which are integrated into one body; the light target is connected with the capacitive ruler vernier of the capacitive ruler. The laser collimation and measuring device with low manufacturing cost, simple operation realizes measurement of shape/position of 100mm-30m for the measured part; and the measurement precision can reach 0.02 mm.
Description
Technical field
The utility model relates to a kind of laser measuring device for measuring, particularly a kind of laser alignment and measurement mechanism.
Background technology
Large-sized structural parts (locomotive or carbody, framework, gate-type or overhead travelling crane) mostly adopts methods such as backguy or leveling ruler (platform), lining instrument to carry out the inspection of morpheme at present, when the morpheme error in measured piece 100mm～30mm scope is measured, measuring accuracy is low, and data acquisition is difficult for.
The utility model content
The purpose of this utility model is, high laser alignment of a kind of measuring accuracy and measurement mechanism are provided.
The purpose of this utility model realizes by adopting following technical scheme:
A kind of laser alignment and measurement mechanism comprise laser collimator, also comprise the light target that holds the grid chi and made by photovoltaic cell, and the appearance grid chi vernier of described light target and described appearance grid chi is connected.
Described light target is made by two quadrants or four-quadrant photovoltaic cell.
Described appearance grid chi vernier is measured the displacement variable of light target, and its data acquisition unit adopts standard interface.
Described appearance grid chi blade is installed on the magnet base.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
Adopt laser collimator, hold the grid chi and form laser alignment and measurement mechanism by the light target that photovoltaic cell is made, realized the morpheme error of measured piece 100mm～30m scope is measured, measuring accuracy can reach 0.02mm.
Description of drawings
Fig. 1 is the utility model utilization structure synoptic diagram.
Reference numeral: the 1st, focal length is adjusted structure, and the 2nd, light-emitting window, the 3rd, light target, the 4th, hold grid chi vernier, the 5th, hold grid chi blade, the 6th, magnet base.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of laser alignment and measurement mechanism, comprise laser collimator, light target 3 and hold grid chi 4, light target 3 is made by two quadrant photovoltaic cells (or four-quadrant photovoltaic cell), holding the grid chi comprises appearance grid chi vernier 4 and holds grid chi blade 5, light target 3 is installed on and holds on the grid chi vernier 4, holds grid chi blade 5 and is installed on the magnet base 6.
Principle of work of the present utility model is: utilize laser beam that collimator sends as seen, be convenient to measure, the microampere electric current that on photovoltaic cell, can produce simultaneously, relevant with the projected position of laser on photovoltaic cell, make light target with two quadrants or four-quadrant photovoltaic cell, by holding the displacement that the grid chi detects light target, can detect the departure of measurement point and collimated laser beam.
Workflow of the present utility model is: the focal length of adjusting laser collimator is adjusted structure 1, make the fixed focal length of laser collimator, laser beam injects on the light target 3 from light-emitting window 2, photovoltaic cell on the light target 3 produces the microampere electric current, hold the displacement that grid chi 4 detects light target 3 by moving, can detect the departure of measurement point and laser beam.Hold grid chi 4 and be connected with data-carrier store, but the collection in worksite data, memory space is big, and data-carrier store adopts standard interface, measurement data can be uploaded to the computing machine that is attached thereto and handle.The utility model can be measured the morpheme error of measured piece 100mm～30m scope, and measuring accuracy can reach 0.02mm.
