Background

The lathe fast automatic tapping is an important mode for internal thread machining, and is particularly applied to large-scale and large-scale machining and assembly. The workpiece is clamped by a three-jaw chuck on the lathe, the screw tap automatically taps forwards along with the workbench, the torque monitoring in the machining process is complicated, a torque sensor is required to be arranged on the lathe and connected with a computer to read a torque value,

if the torque in the tapping process is not monitored, the conditions that whether the diameter of a preformed bottom hole of a workpiece is proper, whether a screw tap is broken, whether a thread is qualified and the like cannot be known by a worker; torque change data in the machining process cannot be simply and quickly obtained in the research process, for example, chinese patents such as CN104384952A and CN203409290U only carry out structural design on the clamping and torque overload protection of the tap, but no research is carried out on the method for obtaining the torque value in the tapping process; the improper bottom hole can lead to incomplete thread tooth shape, and the thread connection strength is directly influenced; the machining effect is not ideal due to the fact that the edge of the screw tap is broken, and the qualified rate of threads is reduced; if the real-time torque is not monitored, the authenticity of research data and the reliability of research results can be directly influenced. A worker usually judges whether the phenomenon that the tap is broken due to the fact that the size value of the diameter of the bottom hole can be judged by self experience, and the accuracy of the abnormal condition in the thread forming process is judged manually, so that the machining efficiency is seriously influenced.

In order to solve the problem of real-time monitoring of tapping torque in the existing lathe fast tapping process, the lathe fast automatic tapping real-time torque monitoring clamp is designed, the torquemeter and the screw tap clamp are integrally designed, the complex operation of monitoring the real-time tapping torque during fast tapping on the lathe is simplified, and the problems of low processing efficiency and inaccurate data caused by the fact that the real-time torque is read, the abnormal processing condition is inconvenient and inaccurate in the tapping process are solved. Can directly read the tapping torque and improve the processing efficiency and the product percent of pass.
