为加工各种结构的内外球面,我们设计了一种成组加工夹具。该夹具可加工SR85mm以下的各种内外球面。经多年生产证明,调整、更换简单,使用方便,生产率高,受到操作者的欢迎。 1.结构原理夹具结构如图所示,由夹具体2、手柄(未示)、蜗杆3、蜗轮5、压板6、转盘7、内外球面刀架89等组成。夹具体2用螺钉固定在车床的刀架座1上。蜗杆3和手柄靠接套(未示)连接。转动手柄时,蜗杆3便带动蜗轮5转动。转盘7用螺钉固定在蜗轮上,而外球面刀架焊接在转盘上也随之转动。夹具在制造
To process the inner and outer spheres of various structures, we have designed a set of machining jigs. The fixture can process a variety of inner and outer spherical SR85mm below. After years of production certification, adjustment, replacement simple, easy to use, high productivity, welcomed by the operator. 1. Structure and principle of the fixture structure shown in Figure, by the clamp body 2, the handle (not shown), the worm 3, the worm gear 5, the platen 6, the turntable 7, the inner and outer spherical 89 and other components. Clamp body 2 with a screw on the turret holder 1 lathe. The worm 3 and the handle are connected to the sleeve (not shown). When the handle is rotated, the worm 3 drives the worm wheel 5 to rotate. The turntable 7 is screwed on the worm wheel, and the outer spherical tool holder is also welded on the turntable and also rotates. Fixture in the manufacture
