Description

Vacuum pump return bend welding positioning platform Technical Field The embodiment of the disclosure relates to the technical field of vacuum pump processing, in particular to a vacuum pump bent pipe welding positioning platform. Background A vacuum pump is a mechanical device used to evacuate gas from a closed container or system, thereby creating a vacuum environment. The core function of the vacuum container is to reduce the air pressure in the container by a physical or chemical mode so as to be lower than the atmospheric pressure, thereby achieving a specific vacuum degree, and the vacuum container is widely applied to the fields of industrial production, scientific research, medical equipment, semiconductor manufacturing, food packaging and the like. In vacuum systems, vacuum pumps are usually connected to reaction chambers, valves, filters, etc., and linear pipes may not meet the requirement of complex space layout, so that bent pipes (also called pipe bends) and straight pipes may be welded, and the direction of the gas flow is changed or the layout of the pipes is adjusted to adapt to the limitation of the installation space of the equipment or optimize the gas flow path. When welding the return bend, can fix the straight tube generally, after the straight tube is fixed, because the both ends of return bend are ninety degrees perpendicular for the staff need place the one end that the return bend was not welded on location platform earlier, then at rotatory return bend, make return bend wait welded one end and straight tube align, however when rotating the return bend and adjusting, because there is frictional force between return bend and the platform, lead to the staff when adjusting the return bend, the contact surface of return bend and platform is liable to appear shifting, even like this the welding end aligns, also can appear the supporting end of return bend after fixed, the problem that the welding surface appears the deviation, consequently, need improve and optimize it.
