The chuck is a clamping device widely used in machine tool processing for rotating workpieces. Through the radial movement of the movable jaws on the chuck body, the rotating workpiece can be clamped and positioned on the corresponding accessories of the machine tool. However, the chuck The clamped workpiece cannot move axially, and usually relies on the axial movement of the tool to complete the processing of different axial positions of the workpiece, and the length of the workpiece that can be clamped by the chuck and the distance that the workpiece can move in the axial direction are Limited by the size of the machine tool, existing chucks cannot meet the clamping requirements of long rod components that need to rotate radially and move axially. For example, the long drill pipe used for oil drilling with a length of about 10 meters to be repaired by spray welding is mainly composed of three parts: the rod body, the box joint and the pin joint. The long drill pipe box joint repaired by welding is used to connect the upper and lower long drill pipes to be repaired by spray welding. It is in contact with the well wall and subjected to severe abrasive wear, resulting in thinning of the joint wall thickness and strength, and easy tripping, resulting in drill string shedding accidents. More than 80% of long drill pipe accidents to be repaired by spray welding occur in this part. Scientific practice has proved that the best solution for the repair of long drill pipe box joints with worn out oil to be repaired by spray welding is to surfacing a wear-resistant layer with high hardness and high wear resistance on the worn surface to restore the oil to be sprayed. Therefore, it is necessary to develop a clamping, rotating and conveying device for long drill pipes to be repaired by spray welding, which are suitable for surface surfacing with high hardness and high wear-resistant layer repairing wear failure.

Now take the oil drilling long drill pipe to be repaired by spray welding as an example to illustrate the implementation steps of the present utility model:

Step 1: Place the workpiece to be processed on the supporting roller bracket and conveying roller bracket in front of the rotating system of the chuck mechanism through a crane. Step 2: Start the motor of the conveying roller bracket, and the rotation of the motor drives the rollers of the conveying roller bracket to rotate. Through the action of static friction, the rollers of the conveying roller bracket drive the workpiece to move to the three-jaw chuck of the chuck mechanism, ensuring that the One end of the long drill pipe repaired by welding passes through the three-jaw chuck, and the long drill pipe to be repaired by spray welding moves to a suitable position (starting position of spray welding process) at the same time. Step 3: Start the motor of the supporting roller bracket to drive the screw to rotate.
