Abstract
The utility model discloses an automatic tracking sensor of adaptive groove width of welding torch oscillation range, wherein a shell is fixedly provided inside with a shaft around which a feeler lever mounting base can rotate; the feeler lever mounting base has the upper end fixedly connected with a swing link of which the upper end is fixedly provided with two photoelectric sensors; the photoelectric sensors are connected with a control circuit of an automatic welding vehicle; a left and a right feeler levers are transversely fixed on the lower end of the feeler lever mounting base; one section of the swing link is the magnetizing section, two electromagnetic coils are transversely arranged on the position corresponding to the magnetizing section. The utility model can complete the automatic tracking and the self adopting control of the width of the welded seam in the welding process; moreover, the utility model has the advantages of simple structure, good reliability and high precision.
Description
Technical field
The utility model relates to the automatic tracking transducer of a kind of welding, the automatic tracking transducer of especially a kind of welding torch amplitude of oscillation self adaptation groove width.
Background technology
Expansion along with construction of hydropower stations scale, penstock and spiral case welding job amount are increasing, more and more higher to the welding quality requirement, therefore the requirement of all position automatic welding seems urgent day by day, in welding automatically, need to solve welding from motion tracking and welding torch amplitude of oscillation self adaptation groove width problem.Domestic automatic welding technique also is in research state at present, and external automatic welding device, automatically weld the mode that welding that dolly and Canadian GULLCO OSClLLATOR type weld dolly automatically all adopts artificial supervision to adjust in good time as the BUG-O type of the U.S., so also will further solve adaptive control problem from motion tracking and weld width.
Summary of the invention
The purpose of this utility model will provide a kind of welding torch amplitude of oscillation self adaptation groove width automatic tracking transducer exactly.
The purpose of this utility model is achieved in that a kind of automatic tracking transducer of welding torch amplitude of oscillation self adaptation groove width, one fixing axle 8 is arranged in the housing 5, feeler lever mount pad 11 can rotate around axle 8, the upper end of feeler lever mount pad 11 and fork 4 are fixedly connected, the upper end of fork 4 is fixed with two photoelectric sensors 2,3, photoelectric sensor links to each other with control circuit on the automatic welding tractor, next end crosswise fixed of feeler lever mount pad 11 has left and right feeler lever 9,10, there is one section to be magnetisable section 6 on the fork 4, with two solenoids 7 of magnetisable section 6 corresponding position lateral arrangement.
Owing to adopt said structure, sensor is installed on the welding torch of automatic weldering dolly, when welding torch is swung, feeler lever touches the groove sidewall, photoelectric sensor sends pulse signal, the control welding torch stops swinging, because feeler lever swings in groove and makes welding torch keep moving along the groove direction always always, realizes that welding is from motion tracking.In magnetisable section corresponding position of fork solenoid being set can prevent between feeler lever and the bevel for welding sidewall sliding friction to take place.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 1 double as Figure of abstract.
The specific embodiment
The automatic tracking transducer of a kind of welding torch amplitude of oscillation self adaptation groove width as shown in Figure 1, one fixing axle 8 is arranged in the housing 5, feeler lever mount pad 11 can rotate around axle 8, the upper end of feeler lever mount pad 11 and fork 4 are fixedly connected, the upper end of fork 4 is fixed with two photoelectric sensors 2,3, photoelectric sensor links to each other with control circuit on the automatic welding tractor, next end crosswise fixed of feeler lever mount pad 11 has left and right feeler lever 9,10, there is one section to be magnetisable section 6 on the fork 4, with two solenoids 7 of magnetisable section 6 corresponding position lateral arrangement.
The utility model is installed on the welding torch of automatic weldering dolly and its control cable and welding torch swing control system of weldering dolly are automatically linked.In the welding process, when welding torch and sensor are swung from left to right, when in a single day right feeler lever touches double V-groove right side wall, put to the right the fork upper end, make the light beam on original right photoelectric sensor become direct projection by stopping, right sensor sends pulse signal, produces two effects: the logic circuit that, passes through the welding tractor control system, welding torch being stopped swinging, enters next program behavior---the right side stops; Two, make right solenoid energising simultaneously, fork top is inhaled to right-hand, make right feeler lever after touching right wall, have one to recess right wall action rapidly left, prevent between the right wall of right feeler lever and groove sliding friction to take place.After finishing right side stop program, enter next program, welding torch and sensor are swung from right to left, and when left feeler lever was run into left wall, the light beam on the left sensor became direct projection by stopping, send pulse signal, swing is stopped, beginning left side stop program, and make left solenoid energising, fork top is inhaled to left, make left feeler lever recess groove left side wall.So repeatedly, realize welding torch amplitude of oscillation self adaptation groove width, feeler lever swings in groove always and makes welding torch keep moving along the groove direction always simultaneously, realizes that bevel for welding is from motion tracking.
