Round silencer assembly welding tooling

Abstract

The invention discloses a round silencer assembly welding tooling, which comprises a bottom plate, V-shaped support blocks, a horizontal positioning pin, a compression block and a compression positioning block, wherein the V-shaped support blocks, the horizontal positioning pin and the compression block are used for positioning a silencer outer tube requiring the assembly welding, and the compression positioning block is arranged at the bottom plate corresponding to the position where a support frame and two air inlet pipes need to be welded on the silencer outer tube and is used for compressing and positioning the support frame and the two air inlet pipes needing to be welded on the silencer outer tube. The round silencer assembly welding tooling has the advantages that the structure is simple and compact, the positioning is reliable, the clamping and the dismounting are convenient, when the round silencer assembly welding tooling is used for welding the two air inlet pipes with connecting flanges of the air inlet pipes and the support frame of a round silencer, the relative dimension precision among all welding elements can be ensured, the welding efficiency and the welding quality are effectively improved, the work intensity of workers is reduced, and the product qualification rate is improved.

Description

technical field [0001] The invention relates to a tool fixture, in particular to a welding assembly tool which can simultaneously position a circular muffler outer cylinder, a bracket and two connecting flanges of an intake pipe. Background technique [0002] The muffler is a device that prevents sound transmission and allows airflow to pass through. A noise reduction device installed in the intake and exhaust system can eliminate aerodynamic noise and block the propagation of sound waves. It is an effective tool for noise control. Its shape and interior There are many forms of structure. The circular muffler includes circular outer cylinder, air intake pipe I, air intake pipe II, exhaust pipe and bracket and other components. The outer ends of air intake pipe I and air inlet pipe II are provided with connecting flanges for Connect and fix the muffler shell with the exhaust pipe of other equipment, and the bracket is welded on the outer wall of the muffler shell to install a...

[0002] The muffler is a device that prevents sound transmission and allows airflow to pass through. A noise reduction device installed in the intake and exhaust system can eliminate aerodynamic noise and block the propagation of sound waves. It is an effective tool for noise control. Its shape and interior There are many forms of structure. The circular muffler includes circular outer cylinder, air intake pipe I, air intake pipe II, exhaust pipe and bracket and other components. The outer ends of air intake pipe I and air inlet pipe II are provided with connecting flanges for Connect and fix the muffler shell with the exhaust pipe of other equipment, and the bracket is welded on the outer wall of the muffler shell to install and fix the muffler. Therefore, whether the positioning of the connecting flange and the bracket of the two intake pipes is accurate determines the Whether the muffler can be installed and used normally, generally, the intake pipe and the connecting flange are welded and fixed first, and then the muffler shell and the intake pipe are positionally welded, and then the muffler shell bracket is positionally welded, not only the efficiency Low, and after multiple welding processes, due to the accumulation of positioning errors, the relative position size of the two intake pipe connecting flanges and brackets often has a large error between the standard value and the muffler cannot be installed on other equipment smoothly. , become unqualified products, resulting in waste of materials and resources
