The invention discloses equipment and a method for detecting the strength of an annular section of a large-diameter TA31 pipe, and relates to the technical field of pipes. According to the annular section strength detection equipment for the large-diameter TA31 pipe, through the design of a composite mechanism, the pipe is placed in the processing mechanism, the pipe space is restrained through the limiting mechanism, the pipe is prevented from moving in the inspection process, danger to workers is avoided, and therefore normal operation of the equipment is kept; the fixing mechanism controls the pipe to rotate and rub with the processing mechanism, so that the effect of cleaning the surface of the pipe is achieved, the situation that stains on the surface of the pipe affect the detection effect is avoided, a hydraulic rod controls a pressing plate to extrude the surface of the pipe, and the detection effect on the annular section strength of the pipe is achieved; therefore, the friction force on the surface of the pipe is increased, the pipe is prevented from shaking in the downward pressing process, and the operation stability is improved.

The utility model provides a quick clamping workpiece fixture for numerical control thread machine tool relates to numerical control thread machine tool technical field, including numerical control thread machine tool, the inside of numerical control thread machine tool is provided with moving platform, the inside of moving platform is provided with quick clamping subassembly, quick clamping subassembly includes motor, the output of motor is connected with gear wheel. In the utility model, the clamping intensity of moving plate can be adjusted through controller, the pressure sensor can play the role of monitoring, the gear wheel can be driven to rotate through the opening motor, through the meshing connection of two groups of racks, drive two groups of moving plate to move and clamping inside, realize the clamping fixation of workpiece, when the pressure of pressure sensor reaches the required pressure, the motor will be automatically closed under the action of controller. Avoided the adjusting range of relative limitedness of the clamping force of existing device, the problem that the flexibility is not high when using in the machining scene of accurate control clamping force.
