Abstract:In order to improve the processing qualified rate and reduce the cost of special bearing，aiming at the problems of low qualified rate of mandrel tapping and easy breaking of tap，a kind of floating anti-breaking tap fixture of mandrel tapping is designed.Taking HQY2632 press wheel bearing mandrel tapping as an example，the working principle and design key points are introduced.It is pointed out that the floating anti-breaking tap fixture has the advantages of simple structure，high precision of thread processing，can realize the automation of tapping process，and solve the problem of breaking tap caused by the blocking chip，different coaxial，poor roughness and too much tapping in automatic tapping.By using the floating anti-breaking tap fixture，the thread processing pass rate is increased to 99.9% after tapping，the service life of the tap is prolonged，and the processing efficiency is increased by about 10%.
Key Words:special bearing；mandrel；tap；tapping；anti-breaking tap fixture
