Description

Technical Field

[0001] The present application relates to the technical field of shaft sleeve processing, and in particular to a tool for processing the inner hole of a shaft sleeve after welding. Background Art

[0002] In industrial production, due to the limitations of welding equipment and technology, after the shaft sleeve is welded and formed, the inner hole inside the shaft sleeve may not meet the use requirements. The shaft sleeve is one of the commonly used parts in mechanical equipment, and inner hole processing is an important link in its processing process. The correct shaft sleeve inner hole processing method can ensure the inner hole accuracy and surface quality, and improve processing efficiency. A Chinese patent discloses a post-welding shaft sleeve inner hole processing tool (authorization announcement number CN219851479U), including a hydraulic press workbench, a base is placed on the hydraulic press workbench, the hydraulic press workbench is fastened with a first clamping plate by hexagon socket bolts, and the first clamping plate is clamped on both sides of the base, a cushion sleeve is inlaid on the top of the base, a workpiece is clamped on the cushion sleeve, guide columns are installed around the hydraulic press workbench, and a pressure plate is slidably installed on the guide column, the bottom of the pressure plate is fastened with a second clamping plate by hexagon socket bolts, and a fixed plate is clamped by the second clamping plate. The use of an oil hydraulic press to drive the pull rod down allows the pull sleeve core of the pull rod to shape the inner hole of the sleeve, which can ensure that the deformation after pulling the sleeve is consistent, can achieve high-precision inner hole shaping, is highly efficient, and is safer. It can be applied to various products that require sleeve shaping after welding. However, when the utility model is performing sleeve processing, due to the long length of the pull rod, when the pull rod is used to process the inner hole of the sleeve, the contact surface is subjected to a large force when the pull rod contacts the machined surface of the inner hole of the sleeve, which is prone to vibration. The amplitude of the vibration increases with the increase of the length of the pull rod, which can easily cause the hole being processed to deform and reduce the processing accuracy.
