我厂采用《机械工人》七九年第三期介绍的定程可逆转式安全攻丝工具一经验,在此基础上,为使用上的方便,对其结构进行了改进。1.原工具的中心齿轮在高速运转中,啮合与脱开易打坏轮齿。现改用槽销传动装置,结构简单,工作可靠。2.原工具的快换安全装置,需根据丝锥尺寸配置多个,调整不便。现改用锥面摩擦安全装置,使结构简化,过载安全。现将改进后的
I plant the “mechanical workers” introduced in 1979 third installment of reversible reversible tapping tools experience, on this basis, in order to facilitate the use of its structure has been improved. 1. The original tool center gear in high-speed operation, meshing and easy to break off the gear teeth. Now switch to groove pin drive, simple structure, reliable work. 2. The original tool quick change safety device, according to the size of the tap to configure a number of adjustments inconvenience. Now use the cone friction safety device, so that the structure is simplified, overload safety. Now will be improved
