Adopt the Mechanical Contact formula sensing that to avoid arclight, flue dust, bias light to disturb for the deficiency that overcomes existing weld seam tracking sensor, utilize photometer head flexible, fast, advantage such as small and exquisite combines it that to develop a kind of optoelectronic contact type weld seam tracking sensor be the task of top priority.
Summary of the invention
According to background technology, the purpose of this utility model is to provide a kind of employing mechanical type sensing head and weld groove to fit tightly the realization soldering joint automatic tracking, when skew has taken place in the sensing head position, optical detection device obtains the shift offset of two-dimensional directional, obtain the accessible analog voltage signal of welding control unit through the signal-processing board processing, thereby realize the optoelectronic contact type weld seam tracking sensor that butt welded seam is followed the tracks of.
To achieve these goals, the utility model is realized by following technology:
A kind of optoelectronic contact type weld seam tracking sensor, mainly by shell body (1), sensing head (2), coupling assembling (3), guide rod (4), linear light battery (5) and signal-processing board (6) are formed, wherein: the bottom device of cylindrical shell body (1) has universal bearing (12), also be provided with on it X to Y to back-moving spring (13), its top is equiped with top cover (11), inside at shell body (1) is equiped with signal-processing board (6) from top to bottom according to the order of sequence, linear light battery (5) and higher source luminance (51); Form coupling assembling (3) by connecting-rod body (31) and thrust ball bearing (32); Guide rod (4) is provided with mirror holder (41) on the top of shell body (1) interior section, reflective mirror (42) is installed on it, guide rod (4) and X to Y to back-moving spring (13) be connected, its middle part is affixed with universal bearing (12), guide rod (4) stretches out shell body (1) and is connected with coupling assembling (3), is spirally connected by connecting-rod body (31) and sensing head (2) again.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the utility model sensing head of having adopted the mechanical type that is fit to various bevel for weldings axially to rotate fits tightly the soldering joint automatic tracking of having realized that groove leads with groove, simple in structure, reliable and practical, be quick on the draw, can be widely used in the various weld joint trackings that groove is arranged.
2, the utility model has utilized flexible, quick, the small and exquisite advantage of photometer head, makes structure collectivity simple, and is cheap, and working service and repairing are simple and easy.

Embodiment
Illustrate by Fig. 1 and Fig. 2, a kind of optoelectronic contact type weld seam tracking sensor, mainly by shell body 1, sensing head 2, coupling assembling 3, guide rod 4, linear light battery 5 and signal-processing board 6 are formed, and wherein: the bottom device of cylindrical shell body 1 has universal bearing 12, also be provided with on it X to Y to back-moving spring 13, its top is equiped with top cover 11, is equiped with signal-processing board 6 from top to bottom according to the order of sequence in the inside of shell body 1, linear light battery 5 and higher source luminance 51; Form coupling assembling 3 by connecting-rod body 31 and thrust ball bearing 32; Guide rod 4 is provided with mirror holder 41 on the top of shell body 1 interior section, reflective mirror 42 is installed on it, guide rod 4 and X to Y to back-moving spring 13 be connected, its middle part is affixed with universal bearing 12, guide rod 4 stretches out shell body 1 and is connected with coupling assembling 3, is spirally connected by connecting-rod body 31 and sensing head 2 again.
Other knows, sensing head 2 is connected with guide rod 4 by coupling assembling 3, guide rod 4 is affixed with universal bearing 12, can carry out universal rotation, but because the reset response of back-moving spring 13, guide rod 4 can only be in X, Y plane with universal bearing 12 be fulcrum along X, the swing of Y direction, thereby realize the transmission of offset deviation; The inclination of guide rod 4 makes the reflective mirror 42 that is embedded on its head reflector bracket 41 with respect to X, angle takes place and changes in the Y plane, what this moment, higher source luminance 51 was sent compares with the hot spot map 53 before guide rod 4 inclinations through the hot spot map 52 on the linear light battery 5 of reflective mirror 42 reflected illumination above reflective mirror 42, the position can change, and then the opto-electronic conversion effect that utilizes linear light battery 5 is converted into measurable change in electric with the variation of hot spot 54 positions, two electric signal X+ through 6 pairs of directions Xs of signal-processing board, X-carries out calculus of differences and the I/V conversion is amplified, can obtain characterizing the analog voltage amount of directions X position change, this voltage is again through amplifying, filtering, can obtain the accessible analog voltage signal of welding robot control device, so just realize the sensing (signal of processing Y direction in like manner) of position while welding accurately.
In order to prevent the reflective influence of shell body 1 inwall, and its inwall is coated with black photodetection.
Know again, because the difference of weld groove shape, need the difformity that press groove, specially go out multiplely to match the sensing head 2 that can be connected with the groove shape with connecting-rod body 31.
