Abstract
A welding shield gas flow control device for silencers comprises a first flowmeter, a pressure regulating valve, a pipeline, a solenoid valve, a welding robot and a PLC unit. The first flowmeter, the pressure regulating valve and the solenoid valve are sequentially installed on the pipeline. An outlet of the pipeline is connected with the welding robot. The solenoid valve is in corresponding signal connection with the PLC unit. A second flowmeter is installed on a robot welding torch of the welding robot. The welding shield gas flow control device for silencers has the advantages that gas flow of the robot welding torch is detected through the simple device; accordingly, flow loss caused by the failure to accurately detect interior pipelines and control components in a work station is avoided, the quality of shield gas at the welded part of the work piece is guaranteed, and unqualified welded silencers are avoided.
Description
Technical field
The present invention relates to automobile exhaust system silencer welder field, particularly silencer welding protection gas volume control device can be controlled the welding process shield gas flow rate.
Background technology
Generally adopt gas shielded welding in the automobile exhaust system muffler ASSY manufacturing process, the uninterrupted of welding protection gas is determining silencer Product jointing quality.Particularly the control to the shielding gas flow amount requires very high especially in luxury car (BMW, AUDI, BENZ) the silencer production welding unit.Guarantee to arrive in the silencer welding workstation workpiece and locate gas flow decision production joint quality with weldering machine gun head (robot arc welding gun head).In the production; the shield gas flow rate controller is installed in the welding workstation outside usually, and protective gas is delivered to robot welding rifle head place through pipeline, because the pipeline transmission loss; the protective gas amount that practical work piece is received and design variant, thus welding quality affected.Therefore, produce in the welding workstation in reality, need a kind of device that can accurately detect welding work pieces place shield gas flow rate, consistent with designing requirement to guarantee welding silencer protective gas amount.
Summary of the invention
The purpose of this invention is to provide silencer welding protection gas volume control device, can solve the above problems.
The technical scheme that adopts is:
Silencer welding protection gas volume control device comprises first flow meter, pressure regulator valve, pipeline, magnetic valve, welding robot and PLC control module.
Its technical essential is:
Be equiped with successively first flow meter, pressure regulator valve and magnetic valve on the pipeline, the outlet of pipeline is connected with welding robot.
Magnetic valve is connected with PLC control module respective signal.
Robot welding gun at welding robot is equiped with the second flowmeter.
Described first flow meter, the second flowmeter, welding robot and PLC control module are known technology, so repeated description not.
The gas pressure that detects according to the second flowmeter, and gas flow in the Adjustment System accordingly make the gas flow of weld reach designing requirement.Thereby assurance weldquality.Described the second flowmeter can adopt various forms of accurate flowmeters.
Its advantage is:
The present invention passes through easy device; detection machine people's welding gun place gas flow; the flow loss of having avoided accurately testing station internal duct and control element to cause, thus the quality of workpiece weld protective gas guaranteed, avoided the generation of the defective silencer of welding quality.
