附图所示的快速移动装置,在我厂的牛头刨床上已经普遍采用。它不仅可以减少大量辅助时间,而且降低了劳动强度。采用上述装置时要注意下列事项:1)轴承支架座最好做长些,以增强旋转轴的刚性;2)这套装置的外部应加防护罩;3)在使用这套装置时,需要停止棘轮机构工作(或停止齿轮转动),以免发生机床事故。 The fast moving device shown in the drawing has been commonly used on the shaper in our factory. Not only does it reduce the amount of time aided, but it also reduces labor intensity. The following items should be taken into consideration when using the above device: 1) It is better to make longer the bearing bracket seat to enhance the rigidity of the rotating shaft; 2) The outside of this device should be equipped with a protective cover; 3) When using this device, Ratchet mechanism work (or stop gear rotation), so as to avoid machine accidents.
