Lathe center

Abstract

The invention discloses a lathe center. The lathe center comprises a plug screw, a spring, a Mohs taper, a mandrel center and an end face sharp tooth pusher dog; the plug screw is connected to the left end of the Mohs taper in a threaded manner, the end face sharp tooth pusher dog is connected to the right end of the Mohs taper in a threaded manner, and the diameter of the right end face of the end face sharp tooth pusher dog is 2 mm to 5 mm smaller than the diameter of a workpiece; sharp teeth are arranged on the end face of the end face sharp tooth pusher dog, and the mandrel center is arranged on an inner hole of the Mohs taper in a movable fit manner; and the spring is installed between the plug screw and a shaft shoulder of the mandrel center in a press fitting manner. By means of the lathe center, no-shutdown end face pulling is achieved, centering and pulling are combined, and the machining speed and quality are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machining fixtures, in particular to a lathe top. Background technique [0002] When processing small shaft parts on ordinary lathes, in order to improve the processing quality and speed, the two ends of the shaft to be processed are often used, that is, a top end is inserted into the spindle hole of the lathe to support the left end of the shaft to be processed, and the tailstock of the lathe is used. The top is against the right end of the processed shaft, and the processing is carried out by using the chicken heart clamp to transmit the torque. Although this processing method can be positioned at one time, the processed shaft does not need to be turned around, but the chicken core clamp is stuck to the processed shaft. The outer diameter transmits torque, and the clamping is troublesome. Every time a shaft is processed, it needs to be stopped for clamping and disassembly, so it is not convenient to use...

[0002] When processing small shaft parts on ordinary lathes, in order to improve the processing quality and speed, the two ends of the shaft to be processed are often used, that is, a top end is inserted into the spindle hole of the lathe to support the left end of the shaft to be processed, and the tailstock of the lathe is used. The top is against the right end of the processed shaft, and the processing is carried out by using the chicken heart clamp to transmit the torque. Although this processing method can be positioned at one time, the processed shaft does not need to be turned around, but the chicken core clamp is stuck to the processed shaft. The outer diameter transmits torque, and the clamping is troublesome. Every time a shaft is processed, it must be stopped for clamping and disassembly, so it is not convenient to use, which increases the labor intensity of the operator and reduces the actual work efficiency.
