Clamp for welding of exhaust system clamshell type rear muffling bag

Abstract

The invention discloses a clamp for welding of an exhaust system clamshell type rear muffling bag. The clamp structurally comprises a welding clamp main body, a clamping control pile, a supporting column, a fixing base and a limiting bottom plate, the clamping control pile is connected to the upper surface of the supporting column in a screwing mode through bolts, the other end of the clamping control pile is connected with the limiting bottom plate, one end of the bottom of the supporting column is perpendicularly welded to the right side surface of the upper portion of the fixing base, the welding clamp main body is arranged above the limiting bottom plate through nuts in a screwing connection mode, the cross section of the limiting bottom plate is of a rectangular structure, one end ofthe right side of the supporting column is screwed on the bottom surface of the limiting bottom plate through nuts, the welding clamp main body is provided with a fixing plate, a locking clamp and anultrasonic welding detection device. According to the clamp, the ultrasonic welding detection device is additionally arranged, the welding quality of a product can be detected in time after welding operation, the problems such as cracks due to welding are avoided, the welding quality can be improved, and the situation that the muffling effect occurs due to the cracks is avoided.

Description

technical field [0001] The invention relates to the field of welding jigs, in particular to a jig used for clamshell-type rear muffler package welding of an exhaust system. Background technique [0002] The rear muffler package is the muffler, which is connected to the muffler from the catalytic converter of the exhaust system. The cross section of the muffler is a round or oval object, which is mostly welded with thin steel plates and installed in the middle or rear of the exhaust system. In the internal position, there are a series of baffles, chambers, orifice tubes and pipes inside. The phenomenon of mutual interference and cancellation of sound wave reflection is used to gradually weaken the sound energy, which is used to isolate and attenuate the pulsation generated when the exhaust valve is opened every time. The pressure needs to be fixed by the clamp during the welding production of the muffler. [0003] However, in the prior art, a fixture used for clamshell-type ...

Problems solved by technology

[0003] However, in the prior art, there is a fixture used for clamshell-type rear muffler package welding of the exhaust system, which is prone to welding deviations during the welding process, and even cracks in the welding, resulting in poor muffler effect
