Description

Technical Field

[0001] The utility model belongs to the technical field of calibrating machines, in particular to a pipe calibrating machine. Background Art

[0002] The calibrator is a device designed to detect and straighten the bending deformation of shaft products. It is mainly used to straighten shaft components to obtain ideal straightness or rotation accuracy, ensuring that the components can achieve assembly accuracy or obtain the minimum cutting allowance for the next process.

[0003] When using existing pipe calibrating machines, the pipe to be straightened is usually clamped with two clamps and bolts, which is cumbersome to operate and requires external tools to release the clamping, which is time-consuming and labor-intensive, and inconvenient for straightening the pipe. Summary of the Invention

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model is provided with a stabilizing tube, a sleeve, a first movable plate, an extrusion block, a rotating member, a spring, and a clamping member. When a pipe fitting needs to be clamped and fixed, the pipe fitting is placed in the stabilizing tube, the sleeve is screwed to move downward, driving the first movable plate and the extrusion block downward. The inclined surface of the extrusion block presses the rotating member, thereby causing the rotating member to rotate.

When the pipe fitting needs to be released from the clamping, the sleeve is screwed to move upward, driving the first movable plate and the extrusion block upward, causing the extrusion block to disengage from the rotating member. The spring rebounds, and the rotating member returns to its original position, thereby releasing the clamping of the pipe fitting. The utility model can clamp the pipe fitting more conveniently, saving time and effort, and provides a more stable clamping, thereby facilitating the straightening of the pipe fitting.

[0013] The utility model is provided with a first motor, a first screw rod, a second movable plate and a third motor. When the first motor is working, the output end of the first motor drives the first screw rod to rotate, thereby driving the second movable plate to move up and down, and then the height of the clamping mechanism can be adjusted. When the third motor is working, the output end of the third motor drives the positioning tube to rotate, thereby driving the clamping mechanism and the pipe to be straightened to rotate, and then the position of the pipe can be adjusted, which is convenient for straightening the pipe.
