L1。
Further analysis, under the driving of transmission mechanism 104, the transform linear motion can be by transformation mechanism 103
Circumferential movement, at this point, if virtual one plane parallel with pedestal 101 of use cuts first axle A, the second axis B and third axis C,
Section is triangle, by depression angle (from pedestal 101 in terms of the top of pedestal 101), first axle A, the second axis B and third axis C generation
Three points of table triangle);Length on the two of them side for being aware of triangle, and wherein one it is known while with unknown
Angle known in situation, the length on unknown side, the displacement meter of the embodiment of the present invention can be calculated according to the triangle cosine law
It calculates unit and calculates the displacement that displacement exactly calculates sliding block 102 under the guidance of the triangle cosine law;With reference to Fig. 4, the second axis B is arrived
The distance of third axis C is the length L of bar, and the distance of first axle A to third axis C is R, when designing displacement detector, L and R
It is known;The angle beta that transformation mechanism 103 turns over can be measured by angular transducer;Therefore, it can be calculated according to the triangle cosine law
Distance L1 of the first axle A to the second axis B.
By above-mentioned analysis, the formula that displacement computing unit of the invention calculates displacement can be obtained, be displaced computing unit
The angle signal that the transformation mechanism 103 is sent is received, and the angle according to corresponding to angle signal is calculated using the following equation
Displacement:
Wherein, X is the displacement of the sliding block 102 linear motion, and L is the length of the bar (transmission mechanism 104), and R is institute
The distance of third axis C to the first axle A is stated, β is the angle that 103 circumferential movement of transformation mechanism turns over.
When β=0 °, sliding block is in original state, does not move, X=L;
When β=180 °, X=L-2R;
When β is within the scope of 0-180 °, X is calculated according to above-mentioned formula.
