Technical field
The utility model relates to a kind of tracking transducer, especially can butt welded seam laterally and the sensor followed the tracks of simultaneously of high and low position.
Background technology
At present, common weld seam tracking sensor has vision, electric arc and mechanical pick-up device etc., and vision and electric arc tracking transducer are easy to be subjected to the interference of arc light, bias light, flue dust etc., thereby erroneous judgement occurs; And general mechanically tracking sensor must be changed different mechanical probes according to the width of groove, and does not possess the short transverse following function, has the workpiece of fluctuations can't realize the high precision welding to the surface.
Summary of the invention
The purpose of this utility model is, overcome the deficiency that existing photoelectricity, vision and arc weld tracking transducer are subject to electromagnetic interference (EMI) and do not have highly sensing, provide a kind of left and right directions and height direction that potentiometer all is installed at sensor, when the groove center changes on the left and right directions, the left and right sides guide wheel stress inequality that contacts with groove, the current potential that drives the left and right directions potentiometer changes; When surface of the work rises and falls when causing guide wheel on short transverse change in location to be arranged, the current potential that drives the short transverse potentiometer changes, and has so just reached the mechanical type weld seam tracking sensor of the two-dimentional sensing of the horizontal and short transverse of groove.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of two-dimentional machinery contact weld seam tracking sensor, mainly form by body (1), guide wheel device (2), vertical sensing device (3) and horizontal sensing device (4), wherein: left guide wheel (21) is connected with the bolt (46) of laterally transposing with right guide wheel (22), and fixed placement is in the U type groove of guide wheel fixed block (23), guide wheel fixed block (23) is connected with the longitudinal sliding block (32) that is connected with vertical potentiometer shifting block (35) by longitudinal sliding block contiguous block (31), is connected with guide wheel spacing adjusting knob (24) in the end of the bolt (46) of laterally transposing; Longitudinal sliding block (32) and two longitudinal spring guide rod (34) suits that are fixed on the web joint (37), and between the upper end of web joint (37) and longitudinal sliding block (32), vertical compression spring (33) being set, longitudinal sliding block (32) drives vertical regulator potentiometer (36) by vertical potentiometer shifting block (35); Big transmission gear (44) is screwed onto with web joint (37), small transmission gear (43) is meshed with big transmission gear (44), and be connected with shaft coupling (47) with body (1) by rotating shaft (48), and shaft coupling (47) is connected with lateral adjustments potentiometer (45); Guide wheel spacing adjusting knob (24) is fixed together with the bolt (46) of laterally transposing, and the screw thread of bolt (46) left and right sides of laterally transposing is reverse.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the utility model can not only be followed the tracks of the groove center in the horizontal, and can regulate the welding gun high and low position automatically according to the fluctuations of surface of the work, and can regulate the relative position of mechanical guide wheel according to groove width, realize the welding of various width grooves, because this tracking transducer is the Mechanical Contact sensing, can not be subjected to the influence of electromagnetic interference (EMI), antijamming capability is stronger.
2, the utility model is simple and compact for structure, and reliable operation guarantees sensing accuracy, and is cheap, and working service is repaired simple and easy.
