Description

A kind of right alignment optical detection apparatus
Technical field
The utility model relates to the right alignment detection field, especially a kind of right alignment optical detection apparatus.
Background technology
In fields such as industry, machinery, scientific researches, often need the right alignment of two round bars is carried out quantitative measurment.As shown in Figure 1, the round bar axis has not overlapped three kinds of situations: 1) as described in Fig. 1 a, the parallel but O point of X1, X2 does not overlap with X1; 2) as shown in Fig. 1 b, angle is arranged for X1, X2 but the O point overlaps with X1; 3) as shown in Fig. 1 c, X1, X2 have angle and O point not to overlap with X1.
Method for measuring coaxiality for round bar is mainly the mechanical collimation method at present.The mechanical collimation method is to be based upon the measuring method of carrying out on mechanical basis in kind, mainly contain and draw steel wire method or gauge method, due to reasons such as steel wire amount of deflection, ambient vibration, fret wears, the measuring accuracy of mechanical collimation method is lower, and owing to adopting contact type measurement, inapplicable under a lot of environment.
The utility model content
Technical problem to be solved in the utility model is: adopt contact type measurement and the lower shortcoming of measuring accuracy in order to overcome existing round bar right alignment, the invention provides a kind of high precision right alignment optical devices based on non-cpntact measurement, this device can be realized non-cpntact measurement, and measuring accuracy is higher.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of right alignment optical detection apparatus comprises the first optical detection apparatus, the second optical detection apparatus, processor, described the first optical detection apparatus, the second optical detection apparatus be detection reference round bar and round bar data image signal in opposite directions respectively, and described the first optical detection apparatus, the second optical detection apparatus output signal are sent to processor.
Described the first optical detection apparatus or the second optical detection apparatus are the ICCD video cameras.
Described the first optical detection apparatus optical axis and the second optical detection apparatus optical axis included angle are φ, and are positioned at and the vertical same plane of benchmark round bar, and described φ angular range is 0 °<φ<180 °.
Can find out from above-mentioned architectural feature of the present utility model, its advantage is
utilize the first optical detection apparatus, the second optical detection apparatus obtains benchmark round bar and the data image signal of round bar in opposite directions, and transfer to processor and process, can obtain the benchmark round bar and detect diameter value, benchmark round bar and round bar axis angle in opposite directions, benchmark round bar and the axle offset value of round bar in opposite directions in data image signal, angle in conjunction with benchmark round bar actual diameter and the first optical detection apparatus and the second optical detection apparatus, calculate benchmark round bar and the right alignment journal offset parameter of round bar in opposite directions, the axis angle parameter, the method can realize non-cpntact measurement, and measuring accuracy is higher.By computer based processor processing digital images signal, detect fast simultaneously, can greatly improve the right alignment detection efficiency of round bar.
