Welding jig used for silencer

Abstract

The invention discloses a welding jig used for a silencer. The welding jig comprises a positioning base, a first clamping unit, a second clamping unit and a third clamping unit; the first clamping unit comprises a first L-shaped branch block, a first square gasket, a first clamping base, a first supporting base, a first rotating block, a first clamping block and a first clamping jig, wherein the first L-shaped branch block is arranged on the positioning base, the first square gasket is arranged on the first L-shaped branch block, the first clamping base is arranged on one side of the first L-shaped branch block, the first supporting base is arranged on the first clamping base, the first rotating block is arranged on the first supporting base, the first clamping block is arranged on one side of the first rotating block, and the first clamping jig is matched with the first rotating block. According to the welding jig used for the silencer, structural design is reasonable, all componentsare matched to meet requirements of the product, it can be achieved that through the effect of supporting, clamping or positioning, points or surfaces to be welded of components of workpieces are arranged in the mode of fitting one another, and after welding is completed through the welding jig, the workpiece component forms a complete workpiece through welding.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a fixture used for positioning welding of a muffler. Background technique [0002] In the traditional welding process, the welding of the workpiece to be welded is usually through simple cooperation between workers. Since the fixed clamping cannot be carried out stably, the stability and accuracy of welding cannot be guaranteed, and it directly leads to The production efficiency is low and the qualification rate of workpiece products is not high, which increases the difficulty of welding and labor costs, and cannot meet the needs of modern workpiece welding batch production, and the current positioning welding structure is relatively complicated, which makes it cumbersome to use and low production efficiency , increasing production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of the prior art and provide a welding fixture f...
