Description

TECHNICAL FIELD

[0001] The utility model relates to diesel engine silencer welding technical field, concretely is a kind of welding fixture of diesel engine silencer. BACKGROUND

[0002] Diesel engine silencer is a kind of device capable of reducing diesel engine exhaust noise. Its main principle is to use acoustic principle and wave dynamics to reduce the propagation and reflection of noise. When diesel engine works, exhaust gas flows out from diesel engine exhaust pipe in the form of high speed. This process will produce noise, mainly due to the pulsation and pressure fluctuation of gas. Diesel engine silencer reduces noise by changing the direction and speed of gas flow. Diesel engine silencer needs to be welded during production, so welding fixture is used to fix the silencer.

[0003] Through searching, patent application No. CN202121411340.5 discloses a welding fixture for diesel engine silencer, which aims at the problem of unstable fixation of cylindrical silencer and provides the following technical scheme. The welding fixture includes a bottom plate, a support fixedly connected to the bottom plate and a support rod slidingly connected to the support. One end of the support rod extends into the interior of the silencer cylinder. The support rod is fixedly connected with a clamping plate, and one side of the clamping plate abuts against the inner side surface of the annular wall of the silencer cylinder. The support is provided with a clamping driving assembly for driving the support rod to clamp the small cylinder of the silencer cylinder between the clamping plate and the support. The bottom plate is provided with a pressing assembly for pressing the mounting seat. The small cylinder is fixed by the clamping plate and the support, and the fixation of the silencer cylinder is completed, which does not affect the welding work on the large cylinder of the silencer cylinder. The structure is simple and reliable.

[0004] However, the patent still has shortcomings. The silencer welding fixture can only clamp and fix silencers of fixed size, cannot meet the clamping and fixing requirements of silencers of different diameters, has low overall applicability of the equipment, and the silencer cannot slide horizontally in the welding fixture for adjustment after being clamped and fixed by the welding fixture. When welding is needed on the part of the silencer that is blocked by the clamped structure, the silencer can only be disassembled, the position of the silencer in the fixture is adjusted again, and then the silencer is fixed again before welding operation can be performed. The operation steps are complicated and time-consuming, which can easily affect the welding efficiency.

[0005] Therefore, we propose a welding fixture for diesel engine silencer. UTILITY MODEL CONTENTS
