Technical field

The utility model relates to the welding procedure equipment, mainly is the technological equipment to the welding of vibration wheel of road roller disc girth joint.

Background technology

Girth joint majority at welding vibration wheel of road roller disc adopts manual welding at present, because the vibrating wheels volume is big, weight is big, welding quality requires high, original manual welding method is difficult to reach even high-quality weld seam requirement continuously, and when welding labour intensity big, efficient is low, especially in welding during girth joint the workman must get into the vibrating wheels the inside and operate, a large amount of heats that produce in the welding process and the badly damaged workman's of smog physical and mental health, particularly the summer of heat sweltering heat the workman can not carry out welding operation for a long time especially, the workman can't guarantee the quality of welding at all under such environment; Easy in addition turning rolls is difficult to the inclination desired angle and reaches the purpose that desirable ship welds, and station can not be realized auto-reverse when the girth joint of the subplate that welds another side, must realize by overhead traveling crane, so not only take overhead traveling crane but also not too safe, the whole welding process inefficiency.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of welding procedure equipment that workpiece welds continuously automatically of once adorning in welding process is provided.

Solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of vibration wheel of road roller disc girth joint robot welding system, it is characterized in that comprising tilt bed revolution positioner, manipulator, the electric welding machine of automatic feeding, the electrical control gear of being with turning rolls, the electric welding machine of tilt bed revolution positioner, manipulator and automatic feeding is connected with electrical control gear respectively.

The beneficial effects of the utility model are: the utlity model has and once adorn the function that workpiece welds continuously automatically, can realize that the automatic revolution of workpiece puts in place, the angle that wing drop is certain, make weld seam can be in the optimum position welding, manipulator's automatic in-position also can realize that welding is from motion tracking, panoramic table can be realized the automatic conversion of station, improves workman's working condition, enhances productivity.Compact integral structure, stable working, safe and reliable, speed of welding is fast, quality is high.

The specific embodiment

Below in conjunction with the drawings and specific embodiments enforcement of the present utility model is further described in detail: a kind of vibration wheel of road roller disc girth joint robot welding system, its structure comprises that mainly the tilt bed of being with turning rolls turns round 1 one of positioners, 2 one of manipulators, the micro computer Waveform Control, 3 one of the CO2/MAG semi-automatic welders of rated duty cycle 100% are electric operation system 4 one covers of master controller with PLC.Turning rolls 1-2 motor frequency conversion speed on the tilt bed revolution positioner 1 is used for adjusting speed of welding, and revolving dial 1-1 motor has the Frequency Converter Control slow-start, prevents starting-impact.Manipulator 2 pneumatic contact seam tracking system 2-2 of outfit and TV monitor system can be realized the monitoring of seam tracking and whole welding process.Be equipped with on the tipping table 1-8 can self-locking leading screw electric lift 1-7, realize the upset of tipping table 1-8 optional position in 0～40 ° of scope, electronic turning rolls 1-2 is housed, welding conductive current maximum can reach brush 1-3, the gear wheel 1-4 of 500A and the panoramic table 1-1 of anti-workpiece tilting mechanism 1-5 is connected with tipping table 1-8 by pivoting support, realize ± 90 ° revolution by transmission system 1-6, transmission system is made up of motor, reductor, pinion, pivoting support etc.Column 2-1 with enough rigidity goes up the guiding slide 2-8 that fixedly has transmission system 2-10 and directive wheel 2-9, have the V-type track, driving rack and be fixed with circuit passband and walking drag chain 2-7 that gas circuit is used and the telescopic arm 2-6 of carriage 2-5 that lays wire feeder by on guiding slide 2-8 tilts 40 ° direction, sliding under the drive of transmission system 2-10, transmission system is by motor, reductor, pinion, compositions such as tooth bar, the front end of telescopic arm 2-6 is equipped with the mechanical arm 2-3 that can swing certain angle that drives by cylinder 2-4, has the probe 2-11 that follows the tracks of usefulness, guiding mechanism 2-12, the pneumatic contact seam tracking system 2-2 of stingy cylinder 2-13 and welding gun clamping and guiding mechanism 2-14 is fixed on the mechanical arm 2-3.

Welding process to utility model further specifies below:

At first all devices of whole system is grouped into zero-bit (both initial positions) during the welding inside weld by electric-control system, point is welded vibrating wheels to be placed on the turning rolls of tilt bed revolution positioner, allow the tilt bed revolution positioner 15 ° of angles of tumbling, turning rolls work makes the workpiece rotation be close to roller then, tilt bed revolution positioner is tumbled 40 ° again, mechanical arm stretches and keeps a straight line with telescopic arm, after telescopic arm reaches certain position, inside of vibrating wheels, mechanical arm resets, the tracking system probe stretches out and begins to seek the location, telescopic arm continues to stretch out, welding gun on last manipulator telescopic arm behind the accurate position that arrives weld seam under the guide of tracking system stops automatically, begins welding behind the welding gun automatic in-position.Whole system was grouped into zero-bit after welding finished, and all equipment are got back to the position of original state.Panoramic table can prepare to carry out the welding of next process by half-twist.Welding at first allows the tilt bed revolution positioner 15 ° of angles of tumbling during outside weld, turning rolls work makes the workpiece rotation be close to roller then, tilt bed revolution positioner is tumbled 40 ° again, the tracking system probe stretches out seeks the location, telescopic arm stretches out, welding gun on last mechanical arm telescopic arm behind the accurate position that arrives weld seam under the guide of tracking system stops automatically, begins welding behind the welding gun automatic in-position.Whole system was grouped into zero-bit after welding finished, and all equipment are got back to the position of original state.
