Silencer pressing device

Abstract

The invention discloses a silencer pressing device. The silencer pressing device comprises a silencer and welding equipment, the silencer comprises an upper cavity, a lower cavity and a sealing ring,an upper cavity cover is arranged at the top of the upper cavity, a fixed end is arranged at the top of the upper cavity cover, the upper cavity cover is fixedly connected with the upper cavity, the fixed end is fixedly connected with the upper cavity cover, the sealing ring is arranged in the upper cavity cover and is clamped with the upper cavity cover, the upper cavity is clamped with the lowercavity; and the welding equipment comprises a shell, a supporting component and a pressure component. The problem that when the upper cavity and the lower cavity are extruded together through a hydraulic cylinder is solved, the position of the upper cavity cannot be fixed, the upper cavity and the lower cavity cannot be tightly attached, and the inclination is prone to occur; the position of thelower cavity cannot be fixed, and inclination occurs during the pressing process of the hydraulic cylinder; if the lower cavity is inclined, due to the fact that the hydraulic cylinder continuously presses down, the working table can be damaged, and the economic loss is caused.

Description

technical field [0001] The invention relates to the field of muffler production equipment, in particular to a muffler pressing device. Background technique [0002] When manufacturing the compressor suction muffler, it is necessary to assemble the upper cavity, the lower cavity, and the metal ring into one, and then use the welding part to assemble it into a finished product. The existing welding method has difficulties in guaranteeing the welding quality and low welding efficiency. Specifically: 1. When using a hydraulic cylinder to squeeze the upper chamber and the lower chamber together, the position of the upper chamber cannot be fixed, resulting in the upper chamber and the lower chamber cannot be tightly fitted, and it is prone to tilt; 2. The position of the lower chamber If the position is not fixed, the hydraulic cylinder will be tilted during the process of pressing down; 3. If the lower chamber is tilted, the hydraulic cylinder will continue to press down, which w...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a muffler pressing device to solve the problem in the above-mentioned background art that when the upper chamber and the lower chamber are squeezed together by a hydraulic cylinder, the position of the upper chamber cannot be fixed, causing the upper chamber and the lower chamber to be separated. The cavity cannot fit tightly, and it is prone to tilt; the position of the lower cavity cannot be fixed, and it will tilt when the hydraulic cylinder is pressed down; if the lower cavity is tilted, the hydraulic cylinder will continue to press down, which will cause damage to the workbench , causing economic loss
