Background technology
See also shown in Figure 1, Fig. 1 is iron and steel enterprise's caliper that is used for the wire product dimensional measurement 100 commonly used, its principle of work is as follows: the light by light source 2 emission by convex lens 4 and 45 ° of reflective mirrors 3 of pair of parallel after, scioptics group 5 is carried out the light path conversion again, enter camera lens 6, and when the rolled piece wire rod passes through caliper 100, can cause the light path formation shade that is obstructed, the size of shade and the diameter of wire rod are proportional, therefore the shade that captures on camera lens 6 is the diameter of wire rod, by the rotation of optical system overall 1, can finish measurement simultaneously to the wire rod appearance profile.But in actual use, the optical element of caliper (as reflective mirror 3, light source 2, convex lens 4 and camera lens 6 etc.) can cause the optical centre skew when installing or change, and must adjust to guarantee the coincidence of optical centre.Because the quality of the adjustment of optical element has determined the power that light finally enters camera lens 6, therefore adjust and whether put in place and will directly have influence on the measurement effect of caliper 100.
At present, the adjustment mode of these caliper 100 optical elements generally all needs earlier the optical system of caliper 100 overall 1 to be dismantled, and is placed on the precision that matches with caliper 100 again and adjusts on the platform, carries out the off-line adjustment, installs at last again.Because above-mentioned dismounting, installment work are very loaded down with trivial details, cause whole adjustment process to need several hours, waste time and energy, and have influenced work efficiency, continue the needs produced thereby can't satisfy rolling line.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of caliper optical element and adjusts pick-up unit, and this video camera can intuitively reflect the adjustment situation of optical element, thereby helps improving regulating the speed of optical element.
For achieving the above object, the utility model adopts following technical scheme:
This caliper optical element is adjusted camera lens one end that pick-up unit is located at caliper, comprises connecting pipe and imaging mirror, and connecting pipe one end and camera lens are connected and fixed, and the imaging mirror is located at the other end of connecting pipe, and is connected and fixed with connecting pipe.
Described imaging mirror is a glass material, and an end face is carved with coordinatometer, and the other end is provided with reflecting coating.
Described connecting pipe one end is provided with external thread, and fixes with the camera lens threaded engagement, and the other end is provided with internal thread.
This pick-up unit also comprises is with externally threaded dead ring, and described imaging mirror is located in the end that connecting pipe is provided with internal thread, and dead ring is located at the outside of imaging mirror, and fixes by threaded engagement and connecting pipe.
In technique scheme, caliper optical element of the present utility model is adjusted camera lens one end that pick-up unit is located at caliper, comprises connecting pipe and imaging mirror, and connecting pipe one end and camera lens are connected and fixed, the imaging mirror is located at the other end of connecting pipe, and is connected and fixed with connecting pipe.This pick-up unit utilize light through optical element finally the imaging on the imaging mirror reflect the adjustment situation of optical element, thereby for the adjustment of optical element provides accurate reference, thereby it is overall to need not to dismantle optical system, just can realize rapid adjustment, not only reduce adjustment difficulty and required time, but also guaranteed quantity-produced efficient.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 3, this caliper optical element is adjusted camera lens 6 one ends that pick-up unit 10 is located at caliper, comprise connecting pipe 11 and imaging mirror 12, connecting pipe 11 1 ends and camera lens 6 are connected and fixed, imaging mirror 12 is located at the other end of connecting pipe 11, and is connected and fixed with connecting pipe 11.Please in conjunction with shown in Figure 4, described imaging mirror 12 is a glass material, and an end face is carved with coordinatometer, and the other end is provided with reflecting coating, is used for imaging.Described connecting pipe 11 1 end outer walls are step-like, and are provided with external thread, fix in order to carry out threaded engagement with camera lens 6; Connecting pipe 11 other end inwalls are step-like, and are provided with internal thread.This pick-up unit 10 also comprises is with externally threaded dead ring 13, described imaging mirror 12 is located in the end that connecting pipe 11 is provided with internal thread, dead ring 13 is located at the outside of imaging mirror 12, and fixing by threaded engagement and connecting pipe 11, thereby imaging mirror 12 is fastened in the connecting pipe 11.
The principle of work of this pick-up unit 10 is as follows:
Please in conjunction with shown in Figure 1; when the optical element of caliper need be adjusted; it is overall 1 to need not to dismantle optical system, only needs the UV protective glass that original screw thread on the camera lens 6 is installed is pulled down, and this pick-up unit 10 is installed on the camera lens 6 by connecting pipe 11 get final product.Open the light source 2 on the caliper 100 then, light is successively by behind each optical element, finally on imaging mirror 12, carry out projection imaging, by the imaging situation on imaging mirror 12, can judge optical element installation situation and optical centre state, and carry out the corresponding optical element of manual adjustment according to imaging, and finally realize rapid adjustment, guarantee the coincidence of optical centre.Below above-mentioned concrete imaging situation is illustrated, see also shown in Figure 5, if the setting angle of the secondary reflecting mirror 3 in the optical element is too small or excessive, can cause part light to exceed secondary reflecting mirror 3 scopes, thereby can there be a in the image that is presented on imaging mirror 12, two brightness zoness of different of b (see figure 6), at this moment, operating personnel can be according to imaging, judge that this reflective mirror 3 exists the upper deviation or lower deviation (being shown in Fig. 6 the upper deviation), thereby carry out manual adjustment reflective mirror 3, until being adjusted to two reflective mirrors 3 parallel, make the image that on imaging mirror 12, is at light as shown in Figure 8, promptly be in the coordinatometer center, and brightness is brighter and even; Because convex lens 4, lens combination and imaging mirror 12 are in same optical centre, if light is image and departs from the coordinatometer center on imaging mirror 12, illustrate that optical centre does not overlap, cause image generation left avertence or right avertence, at this moment, operating personnel can be according to imaging, by light source 2 or camera lens 6 or convex lens 4 being adjusted accordingly (being to adjust on the direction of vertical optical system disk 1), the image that is on imaging mirror 12 is finished adjustment also as shown in Figure 8.
Adopt pick-up unit 10 of the present utility model, need not to dismantle optical system overall 1, also need not to adopt the precision that matches with caliper 100 to adjust platform, just can realize the rapid adjustment of optical element, whole adjustment process is no more than 20 minutes, not only reduce adjustment difficulty and required time, but also guaranteed quantity-produced efficient.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
