Silencer exhaust pipe welding mold

Abstract

The invention discloses a silencer exhaust pipe welding mold, which comprises a bottom plate, an exhaust pipe positioning assembly and a silencer casing positioning assembly, wherein a silencer support frame positioning assembly comprises a positioning guide plate and a moving pin assembly, and a silencer support frame is aligned with a welding point of a silencer casing through being positioned behind a moving pin. The silencer exhaust pipe welding mold adopts a multi-point fast positioning structure and comprises the exhaust pipe positioning assembly and the silencer casing positioning assembly, a fast driven moving positioning structure is combined, and a moving clamp head and an exhaust pipe limiting clamp structure are utilized, so the welding positioning process is standardized, the form and position accuracy of the welding processing can be ensured, the work efficiency is improved, the additional stress after the installation of a silencer is reduced or even eliminated, the service life is prolonged, the work intensity of operators is reduced, and the production cost and the use cost are saved.

Description

technical field [0001] The invention relates to a welding processing auxiliary device, in particular to a welding mold for muffler exhaust pipe. Background technique [0002] Welding process is a way of combining and fixing different parts by welding. For the welding between small parts, the self-weight is light, and the positioning effect is not good, which is prone to deviation. Unlike other connection methods, welding is a non-detachable connection. If there is a large accuracy error, it will affect the quality of the entire product and even be scrapped. [0003] In the prior art, the welding between the various parts of the small muffler requires relatively precise precision standards to ensure that there is no interference between the various parts when the muffler is installed; especially in the process of welding the exhaust pipe of the muffler, due to the need Compatible with components such as brackets to ensure high welding accuracy. In the prior art, the shape ...

Problems solved by technology

However, in the prior art, the shape and position error is generally guaranteed by the experience of the operator. Generally, the spot welding is positioned first, and then the overall welding is performed, which makes the production efficiency low, the welding processing scrap rate is high, the processing cost is increased, and the labor intensity is increased.

Since the accuracy cannot be guaranteed, various forms of additional stress will appear after the muffler is installed, resulting in a low service life of the muffler installation structure and prone to failure
