The invention discloses a turning device for a long and thin threaded shaft. The turning device for the long and thin threaded shaft is arranged on a large carriage of a lathe and comprises a base, a guide sleeve, a telescopic sleeve, a tool reset ring, thread length control mechanisms and tool assemblies. The turning device has the advantages that scales are arranged on the outer circle surface of the long and thin shaft close to a shaft ring so that the length value of threads to be turned can be accurately adjusted by adjusting the axial positions of adjusting screw sleeves; three sets of turning tools which are uniformly distributed in the circumferential direction are arranged so that the deformation of the threaded shaft in the turning process can be reduced, and the machining quality can be guaranteed; an inclined surface A and an inclined surface C which can make contact with each other or can be separated from each other are arranged so that finish machining of the threads can be accurately realized, and the situation of tool breakage can be effectively prevented; and the tool reset ring is arranged so that the three sets of turning tools can contract towards the center at the same time, and therefore the operation can be rapid and convenient.

The invention provides an automatic numerical control lathe tailstock control method. A connection device for achieving automatic connection and disconnection between a lathe saddle and a tailstock of a numerical control lathe through an air cylinder is utilized. The connection device comprises a connection pillar, a rotating arm assembly, a drive assembly and a drill bit assembly, the middle of the connection pillar is provided with an annular groove, the shaft end of the connection pillar and the side face of the tailstock are provided with a pair of sensors, the rotating arm assembly comprises a rotating arm, a rotating shaft, a shaft sleeve and a big gear, the shaft sleeve is fixed to the front side face of the tailstock of the numerical control lathe, the rotating shaft penetrates through the shaft sleeve, the front end of the rotating shaft is fixedly connected with the rotating arm, the other end of the rotating shaft is fixedly connected with the big gear, the front end of the rotating arm is provided with a hook portion capable of being clamped into an annular groove, the drive assembly comprises a rack, an air cylinder, a magnetic exchange valve, a rack guide groove, a reset switch and a controller, the controller is mounted in a lathe power distribution cabinet and electrically connected with a numerical control system and the magnetic exchange valve, and the rest switch is mounted in front of the lathe saddle of the numerical control lathe and electrically connected with the controller.

The invention relates to an ultrasonic vibration honing technique, in particular to a radial ultrasonic honing device. By adoption of the radial ultrasonic honing device, the problems that an existing ultrasonic vibration honing device is complicated in overall structure, high power and high energy are difficult to obtain, the storage oil lubrication performance of a workpiece is prone to being affected, and transducer operation desynchrony is prone to being caused are solved. The radial ultrasonic honing device comprises an outer barrel, supporting rods, an upper cover, a lower cover, a floating mechanism, an ejector rod, a limiting barrel, a linear bearing, an inner barrel, a supporting barrel, a reset spring, an expand mandrel, guide bars, rare-earth super-magnetostriction transducers, inner pin rods, oilstone bases, outer pin rods, oilstone, annular springs and a collecting ring. The radial ultrasonic honing device is applicable to ultrasonic vibration honing.
