堆焊设备及其用于电火花沉积的气体保护装置
摘要：
本发明提出一种用于电火花沉积的气体保护装置及具有它的堆焊设备，该气体保护装置包括：支撑件；调节件，调节件在第一方向上可调节地连接到支撑件上；气体传输管，气体传输管在第二方向上可调节地连接到调节件上；和气体源，气体源与气体传输管连通以提供保护气体。根据本发明实施例的用于电火花沉积的气体保护装置，通过调节件相对于支撑件以及气体传输管相对于调节件的位置可调节，因此根据电极和工件接触的具体部位可在两个方向上自由且方便地调节气体传输管的出气口位置，进而准确地向火花放电区输气，充分地形成保护气氛围以达到最佳隔绝空气的效果。
摘要（英）：

The invention provides a gas protection device for electric spark deposition and surfacing equipment with the gas protection device. The gas protection device comprises support members, an adjusting member, a gas delivery pipe and a gas source. The adjusting member is adjustably connected to the support members in the first direction. The gas delivery pipe is adjustably connected to the adjustingmember in the second direction. The gas source is communicated with the gas delivery pipe to provide protective gas. According to the gas protection device for electric spark deposition, the positionof the adjusting member relative to the support members and the position of the gas delivery pipe relative to the adjusting member are adjustable, so that the position of a gas outlet of the gas delivery pipe can be freely and conveniently adjusted in two directions according to the specific position where an electrode is in contact with a workpiece, gas is accurately delivered to a spark discharge area, and a protective gas atmosphere is sufficiently formed to achieve the optimal air isolation effect.
