AI Technical Summary
The existing drill pipe straightening operation is inefficient and makes it difficult to effectively verify that the straightening effect is unsatisfactory, resulting in poor straightening performance.
A straightening device for drill pipe processing was designed. It uses a clamping seat and a motor to drive the screw to rotate and straighten the drill pipe. It also uses an electrical contact and an alarm to detect the straightness of the drill pipe in real time and issue an alarm in a timely manner.
This significantly improves the accuracy and efficiency of drill pipe straightening, ensuring that drill pipe straightness detection is fast and effective.

Abstract
Claims
1. A straightening device for drilling rod processing, comprising a base and two clamping seats, characterized in that: A screw is horizontally mounted on the base, and the screw is powered by a first motor on the base. Two corresponding first base plates are fixedly connected below the two clamping seats. The bottom of the first base plate is horizontally slidably mounted on the base, and a threaded hole is horizontally opened through the center of the first base plate. The threaded holes of the two first base plates are respectively threaded onto the positive and negative threads on the left and right sides of the screw. The two ends of the drill rod pass horizontally through and are fixed in the two clamping seats. A circular movable frame is vertically movable between the two clamping seats. A second base plate is fixedly mounted at the bottom of the movable frame, and the bottom of the second base plate is horizontally slidably mounted on the base. A through hole is provided on the left and right sides of the base plate, and the screw is horizontally movably inserted through the through hole; the middle of the movable frame has an opening, and multiple clamping blocks are slidably provided on the side of the movable frame at equal angles along its radial direction; an adjustment component connected to the clamping blocks is provided in the cavity inside the movable frame, which is used to drive the clamping blocks to move synchronously along the radial direction of the movable frame; a slide rod is slidably installed inside the clamping block along the radial direction of the movable frame, and a roller is installed at one end of the slide rod, which abuts against the drill rod; a limit contact block is fixed at the other end of the slide rod, and an electrical contact corresponding to the limit contact block is provided on the clamping block, which is electrically connected to the alarm.
2. The straightening device for machining of drill pipes according to claim 1, characterized in that: The adjustment assembly includes a rotating ring, a gear ring, and a gear. The rotating ring is concentrically mounted in the cavity of the movable frame. The cavity also contains multiple swing rods corresponding to the clamping block. One end of each swing rod is rotatably connected to the cavity, and a first sleeve is slidably fitted onto the middle of the swing rod. The first sleeve is rotatably connected to the rotating ring. The other end of each swing rod is slidably fitted onto a second sleeve, which is rotatably connected to the bottom of the clamping block. The gear ring is mounted on the outer circumference of the rotating ring. The gear meshes with the gear ring and is powered by a second motor in the cavity.
3. The straightening device for machining of drill pipes according to claim 1, characterized in that: The side of the movable frame has multiple grooves communicating with the movable opening along its radial direction, and the bottom of the grooves communicates with the cavity; the clamping block is slidably installed on the side wall of the groove.
4. The straightening device for machining of drill pipes according to claim 1, characterized in that: The clamping block has an inner hole along the radial direction of the movable frame, and the slide rod slides through the inner hole.
5. The straightening device for machining of drill pipes according to claim 1, characterized in that: A spring is fitted onto the slide bar, and the two ends of the spring abut against the mounting plate of the roller and the clamping block, respectively.
6. The straightening device for machining of drill pipes according to claim 1, characterized in that: The clamping blocks are provided in four parts, with two symmetrically arranged in the vertical and horizontal directions respectively.
7. The straightening device for machining of drill pipes according to claim 1, characterized in that: The base is equipped with slide rails in the left and right directions, and both the first base plate and the second base plate are slidably mounted on the slide rails.
