Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing.
[0013] as attached Figure 1-2 As shown, a double-end double-piston spindle for a machine tool of the present invention is composed of a spindle main body 1, a bearing, a gland 2, a spindle 3, a belt 4, an oil cylinder 5 and a fixture 6, and the spindle 3 is rotatably connected to the In the main shaft body 1, the belt 4 is connected to the main shaft to drive the main shaft 3 and the clamped workpiece 7 to rotate. The outside of the bearing is fixed by the gland 2. At the end, the jig 6 is driven by the oil cylinder 5, wherein the gland 2, the bearing, the oil cylinder 5 and the jig 6 are all arranged in pairs and arranged substantially symmetrically along the longitudinal centerline of the main shaft body 1. The clamp 6 may be a chuck or collet.
[0014] The invention relates to a double-end surface double-piston main shaft for a machine tool, which can complete the pro...
