Abstract
The utility model relates to deformation measurement tools, in particular to a step measurement instrument without a fixed-length pole. The step measurement instrument without the fixed-length pole comprises a straight ruler, and three laser range finders with light rays perpendicular to the straight ruler are fixed on the straight ruler at the same interval. By the step measurement instrument without the fixed-length pole, deformation of large casings in complicated environment can be measured precisely.
Description
Technical field
The utility model relates to the deformation measurement instrument, relates in particular to a kind of appearance that strides.
Background technology
The appearance that strides is that form and position tolerance detects a device in (deflection), can measure the linearity and the flatness of measured piece through the appearance that strides.But common stride that to measure all be that simple plane is comparatively measured; Under complex environment comparatively, stride when measuring (like the last furnace shell deformation measurement); Because there are many barriers on the testee surface, and it is less to detect the space, just can't measure with the appearance that strides.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of no connecting-rods with constant lengh appearance that strides is provided.The utility model can be realized the accurate measurement of large-scale housing distortion under the complex environment.
For addressing the above problem, a kind of no connecting-rods with constant lengh appearance that strides, it comprises straight chi, equidistance is fixed with the laser range finder of three light perpendicular to straight chi on the said straight chi.
The common appearance that strides is two connecting-rods with constant lenghs, a sounding rod.Obtain the deflection of testee through the length difference that calculates connecting-rods with constant lengh and sounding rod.Connecting-rods with constant lengh and sounding rod that the utility model cancellation strides appearance adopt laser range finder to replace connecting-rods with constant lengh and sounding rod, reduce with regard to the volume that makes the appearance that strides like this, solve the problem that (little space, many obstacles) strides and measure under the complex environment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the synoptic diagram of the utility model when the state of measurement.
Embodiment
As depicted in figs. 1 and 2, a kind of no connecting-rods with constant lengh appearance that strides, it comprises straight chi 4, equidistance L is fixed with the laser range finder 1,2 and 3 of three light perpendicular to straight chi 4 on the said straight chi 4.
During operation, when laser range finder 1 range finding (B1) equals laser range finder 2 range findings (B2) (B1=B2), read the numerical value (B3) of laser range finder 3; By the routine appearance data processing method deal with data that strides.
Claims (1)
1. no connecting-rods with constant lengh appearance that strides, it comprises straight chi, it is characterized in that, equidistance is fixed with the laser range finder of three light perpendicular to straight chi on the said straight chi.
