Description
Technical field
The invention belongs to mechanical measurement fields, and in particular to a kind of link-type range unit.
Background technique
Ranging has application in fields such as aerospace, the earth mapping, civil construction, mechanical engineerings, and laser ranging is because of it
The advantages that monochromaticjty is good, high directivity, fast spread speed is applied to a variety of ranging fields, but some occasions are surveyed using laser
Away from and be not suitable for, such as the severe place of production environments such as cement plant, dust factory, the serious machinery plant of greasy dirt, this environment
Feature is: can not spatially provide a suitable access for the propagation of laser, can not environmentally provide suitable laser propagation
Atmospheric conditions.
Summary of the invention
The object of the present invention is to provide a kind of link-type range units, can effectively make up the shortcomings that laser ranging.
The invention is realized in this way as shown in figs. 1 to 6 including pedestal 1, cross bar 4, vertical bar 6, fixed beam 7, cylinder turn
Kinetoplast 8, the dial plate 9 equipped with indicator 10 and angular transducer, connection relationship is: fixed beam 7 is laterally fixedly connected on fixed body
On, pedestal 1 is fixed together with testee, and left and right threaded post 1.1,1.1 ' is fixed on above pedestal 1 vertically, left and right
Compressed spring 2,2 ' is set in left and right threaded post 1.1,1.1 ', the left end of cross bar 4 be sleeved on left and right threaded post 1.1,
It on 1.1 ', is fastened by left and right nut 3,3 ', the right end of cross bar 4 and 7 lower end of vertical bar are hinged by pin shaft 5, cross bar 4 and fixation
Beam 7 is parallel；The right end of fixed beam 7 is formed with square through hole 7.2, and the left and right frustum of a cone is formed respectively on the two sidewalls of square through hole
7.1,7.1 ', cylindrical pivot body 8 is mounted on the square through hole of 7 right end of fixed beam by the conical bore 8.1,8.1 ' at its both ends
In 7.1, vertical bar 6 passes through the through-hole 8.2 on cylindrical pivot body 8, and top is connect with dial plate 9, and pointer 10 is equipped in dial plate 9
And angular transducer, angular transducer were both connect with pointer 10, were connected to a computer further through wired or wireless.
Advantages of the present invention and good effect are:
(1) the configuration of the present invention is simple, cost is relatively low, practical, and expensive laser ranging can be substituted in certain occasions
Device；(2) present invention can be used for the serious occasion of dust, greasy dirt, and the measurement accuracy of link mechanism is in this context
Guarantee；(3) measurement accuracy of the invention is not influenced by factors such as environment temperature, humidity.

Specific embodiment
As shown in Figure 1: when testee is mobile, the pedestal 1 being fixed on testee be will move with, due to pedestal
1 is connect with the left end of cross bar 4 by left and right screw rod 1.1,1.1 ' and left and right spring 2,2 ' and left and right nut 3,3 ', cross bar 4
It is moved synchronously also with testee；Due to cross bar 4 right end and the lower end of vertical bar 6 be hinged by pin shaft 5, and it is horizontal
Bar 4 is parallel with fixed beam 7, and vertical bar 6 passes through the through-hole 8.2 on the cylinder rotor of fixed beam 7, so, 6 run-off the straight of vertical bar；
The upper end of vertical bar 6 is connected directly with instrument board 9, and instrument board 9 will be moved with the movement of vertical bar 6 and run-off the straight, indicator 10
It is mounted in instrument board 9 with angular transducer and indicator 10 is connected with the main shaft of angular transducer, since indicator 10 has centainly
Weight and angular transducer torque it is very small, so indicator 10 is always straight down, therefore the main shaft of angular transducer
It will be rotated with the rotation of indicator.The change of object distance has converted angled change at this time；Assuming that angle sensor
The initial angle that device measures is θ1, termination point θ2, this means that the distance that testee unidirectionally moves is converted to θ=θ2-
θ1Angle change.It is L by designing the distance between determined cross bar 4 and fixed beam 7, it then can by simple algorithm
Acquire the amount of movement x of testee, it may be assumed that x=L × (tan θ2-tanθ1)。
