Description

Technical Field

[0001] The utility model relates to the technical field of long axis correction, in particular to a slender axis straightening and correction device. Background Art

[0002] A shaft with a length-to-diameter ratio greater than 25 is called a slender shaft. Slender shafts have poor rigidity. During the machining process, due to the influence of multiple factors such as machine tools and cutting tools, the workpiece is prone to bending and drum-shaped. A correction device is required to correct the long shaft.

[0003] There is a device for straightening and correcting a slender shaft (its authorization announcement number is: CN220837310U). This correction device starts the cylinder to drive the correction block to move downward to achieve pressure and correction of the long shaft. However, since the correction block is not convenient for adjusting the horizontal position, this correction device can only achieve pressure and correction of the fixed position of the long shaft, which makes the practicality of the correction device low. At the same time, in the process of pressing and correcting the bent long shaft, the long shaft after correction will continue to become longer, and manual adjustment of the position between the two sliders is required, which is inconvenient to operate. Therefore, we propose the utility model to solve the above problems. Utility Model Content
