Abstract
The utility model relates to the field of carbon dioxide welding, in particular to an alarming device for preventing carbon dioxide welding from being missed and reduced. The alarming device comprises a reset switch, a first travel switch, a second travel switch, a first intermediate relay, a second intermediate relay, an acousto-optic alarm, a welding length signal detecting device, a PLC and a switching power supply. The reset switch, the first travel switch, the second travel switch, the first intermediate relay, the second intermediate relay, the welding length signal detecting device and the switching power supply are electrically connected with the PLC. The first intermediate relay is electrically connected with a welding machine air valve control end coil, and the second intermediate relay is electrically connected with the acousto-optic alarm. The alarming device has the advantages that the alarming device can help operators to rapidly judge whether welding missing of welding seams of a product occurs or not and the welding length is shortened or not in the production process, and therefore welding missing of the welding seams and shortening of the welding length are avoided.
Description
Technical field
The utility model relates to carbon dioxide arc welding field, relates to specifically a kind of warning device that prevents that carbon dioxide arc welding solder skip from welding less.
Background technology
At present, in carbon dioxide production process, although technological requirement file has shown weld length, because operative employee operates the reason such as unskilled, absent minded, cause product solder skip weld seam, weld length is inadequate.Solder skip, weld length less and all product quality is produced and to be had a strong impact on.For fear of product solder skip weld seam, weld less weld length, the necessary 100 ﹪ inspections of operative employee, inspector must check by 100 ﹪, loses time.
Utility model content
The purpose of this utility model is to address the above problem, and a kind of warning device that prevents that carbon dioxide arc welding solder skip from welding is less provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
Prevent the warning device that carbon dioxide arc welding solder skip is welded less, comprise reset switch, the first travel switch, the second travel switch, the first auxiliary reclay, the second auxiliary reclay, audible-visual annunciator, weld length detection signal device, PLC, Switching Power Supply; Reset switch, the first travel switch, the second travel switch, the first auxiliary reclay, the second auxiliary reclay, weld length detection signal device, Switching Power Supply are electrically connected to PLC respectively, the first auxiliary reclay is electrically connected to welding machine Air Valve Control end-coil, and the second auxiliary reclay is electrically connected to audible-visual annunciator.
Weld length detection signal device comprises magnetic switch and the carry magnet mounting disc matching, carry magnet mounting disc is round turntable, some small magnet pieces are arranged at the even interval of circumferential edges of round turntable, carry magnet mounting disc is fixed on carbon dioxide wire feed rolls, and magnetic switch is arranged on magnet mounting disc vertical lower induced magnetism signal.
The circumferential edges of round turntable is furnished with four small magnet pieces.
The beneficial effects of the utility model are: help operating personnel to judge fast in process of production whether solder skip weld seam of product, weld less weld length, thereby avoid solder skip weld seam, the generation of welding less weld length.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: referring to Fig. 1, Fig. 2.
Prevent the warning device that carbon dioxide arc welding solder skip is welded less, comprise reset switch 2, the first travel switch 3, the second travel switch 4, the first auxiliary reclay 5, the second auxiliary reclay 6, audible-visual annunciator 7, weld length detection signal device, PLC1, Switching Power Supply 8; Reset switch 2, the first travel switch 3, the second travel switch 4, the first auxiliary reclay 5, the second auxiliary reclay 6, weld length detection signal device, Switching Power Supply 8 are electrically connected to PLC1 respectively, the first auxiliary reclay 5 is electrically connected to welding machine Air Valve Control end-coil, and the second auxiliary reclay 6 is electrically connected to audible-visual annunciator 7.
Weld length detection signal device comprises magnetic switch 9 and the carry magnet mounting disc 11 matching, carry magnet mounting disc 11 is round turntable, some small magnet pieces 10 are arranged at the even interval of circumferential edges of round turntable, carry magnet mounting disc 11 is fixed on carbon dioxide wire feed rolls, and magnetic switch 9 is arranged on magnet mounting disc 11 vertical lower induced magnetism signals.
The circumferential edges of round turntable is furnished with four small magnet pieces 10.
Specific design principle explanation: the reset switch in this device, the first travel switch, the second travel switch, the first auxiliary reclay, the second auxiliary reclay, audible-visual annunciator, weld length detection signal device, PLC, Switching Power Supply all connect input terminal line bank 12.Small magnet is arranged in the magnet placing hole of magnet mounting disc, and every 90 degree are laid a magnet, and magnet mounting disc is fixed on carbon dioxide wire feed rolls by nut, and the capable switch of magnetic is arranged on magnet mounting disc vertical lower and is no more than 1CM apart from magnet mounting disc edge.From welding machine Air Valve Control end, draw signal to auxiliary reclay K1 coil.This signal judges whether at welded condition.Magnetic switch signal is by auxiliary reclay K1 access PLC, and travel switch 1 and travel switch 2 its effects are to have judged whether welding work pieces.Magnetic switch provides weld length detection signal to PLC.Reset switch plays the function that resets and report to the police.PLC is electrically connected to audible-visual annunciator by controlling the normally open contact of opening of auxiliary reclay K2, and makes PLC can control audible-visual annunciator action.Workpiece is placed on and on fixture, triggers travel switch and make PLC receive signal in process of production.During welding machine welding, make relay K 1 coil adhesive send a signal to PLC, PLC enters weld length detection automatically by coherent signal.And weld length detect be by carbon dioxide welding machine wire feed rolls rotate the magnet that makes in magnet mounting disc successively induced magnetism switch send a signal to PLC, PLC record data.After operative employee completes welding operation, workpiece leaves fixture triggering travel switch 2 and sends a signal to PLC, and PLC carries out Data Comparison processing.Once the data value of record is lower than setting value, description operation work is welded weld length or solder skip less, and PLC outputs signal to relay K 2 coils and obtains electricly, triggers photoelectric alarm action, sends flicker ruddiness and chimes of doom, and prompting workpiece welds or solder skip less.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
