排气管外形复杂,又是毛坯定位,使用一般夹具进行加工比较困难,效率低,车好的排气管壁厚又不均匀。使用如图中所示的涨簧夹具来加工,质量稳定。如图:在车床上加工排气管,车头端使用拨盘顶尖顶在工件工艺顶尖孔上,把夹具放人工件内孔(毛 Exhaust pipe complex shape, but also rough positioning, the use of general fixture for processing more difficult, low efficiency, good car exhaust pipe wall thickness and uneven. Use the spring clamp as shown in the picture to process with stable quality. Figure: The exhaust pipe processing lathe, the front end of the dial using the top of the top of the top of the workpiece technology, the fixture into the workpiece hole (hair
