Technical Field

[0001] This application relates to the field of straightening devices, and in particular to a straightening device for machining shaft workpieces. Background Technology

[0002] During the processing of shaft workpieces, they may be subjected to compression due to handling or transportation, which reduces their straightness and affects subsequent work. Therefore, straightening is required. However, under normal circumstances, measuring the straightness of shaft workpieces manually with simple tools is inefficient. Subsequently, manual pressing is used to straighten the shaft workpieces to increase their straightness, but this process is also inefficient. Utility Model Content

The top straightening component and the measuring component are placed horizontally.

[0006] Preferably, the upper end of the support frame has a placement groove, and two rollers are rotatably connected to the side wall of the placement groove, with the two rollers arranged symmetrically.

[0007] Preferably, a limiting plate is provided on the outer side of the support frame.

[0008] Preferably, the top straightening component includes a mounting bracket and a top straightening rod. The top straightening rod slides vertically within the side wall of one end of the mounting bracket. A lower nut and an upper nut are rotatably connected to the circumferential side of the top straightening rod. The upper nut and the lower nut are located on the upper and lower sides of one end of the mounting bracket, respectively. A return spring is sleeved on the circumferential side of the top straightening rod. The return spring is located between the mounting bracket and the upper nut.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When straightening a shaft workpiece is required, first place both ends of the shaft workpiece in the placement slots of the two support frames. Then, with the assistance of two rollers, the shaft workpiece can be rotated. At the same time, the straightness of the shaft workpiece can be detected by the measuring piece. After that, press the upper end of the straightening rod and squeeze the return spring to bend the shaft workpiece, thereby increasing the straightness of the shaft workpiece and improving the efficiency of straightening the shaft workpiece.

[0014] 2. When encountering shaft workpieces of different specifications, first slide the lifting frame on the base frame to adjust the height of the measuring device. Then, lock the base frame and the lifting frame with the locking device. Then, according to the length of the shaft workpiece, start the drive motor to rotate the threaded rod. With the cooperation between the threaded rod and the slider, the two sliders move closer or further apart in the limit groove, thereby changing the distance between the two support frames to adapt to shaft workpieces of different specifications.
