Abstract

The invention provides an automatic positioning and clamping device of a drill rod and a drill collar on a pipe threading lathe. The device comprises a lathe bed, a tail platform, a headstock and a bracket multi-group carrier roller. The bracket multi-group carrier roller is arranged on one side of the lathe bed, the headstock and the tail platform are arranged on the lathe bed, and the headstock (8) is arranged on one side close to the bracket multi-group carrier roller (10). According to the device and method, automatic feeding, positioning, clamping and discharging of workpieces can be achieved. The purpose of the device and method is to achieve the full-automatic machining processes, including feeding and discharging, of the numerical control pipe threading lathe.

Description

technical field [0001] The invention is used in the field of metal cutting and processing, and relates to a pipe thread lathe, which takes the axis line of the old thread as a reference before repairing and turning the old internal and external threads at both ends of long pipe workpieces such as used petroleum drill pipes and drill collars. Automatic positioning, clamping, and automatic loading and unloading devices. Background technique [0002] In the petroleum and geological drilling industry, the drill bits that are drilled into the ground thousands of meters deep are composed of hundreds of drill pipes and drill collars, which are screwed one by one by the threads at both ends, and connected to the ground drilling rig. The ground drilling rig passes through these The drill pipe and drill collar transmit the torque to the drill bit. These drill pipes and drill collars need to be unloaded one by one after completing the drilling work of a well, recovered, repaired, and...
