Description

TECHNICAL FIELD

[0001] The utility model relates to a device for preventing the disengagement of a chuck and a connecting rod of a honing machine. BACKGROUND

[0002] A honing machine is a grinding machine that uses a honing head to finish the surface of a workpiece. It is mainly used to hone the holes of workpieces in the manufacturing of automobiles, tractors, hydraulic components, bearings, and aircraft. There are two types of honing machines: vertical and horizontal. The vertical honing machine has a short main shaft working stroke and is suitable for honing the holes of cylinder blocks and housings. The honing head, which is embedded with an oil stone, is rotated by the vertically positioned main shaft and simultaneously performs vertical reciprocating feed motion under the drive of a hydraulic device. The horizontal honing machine has a long working stroke and is suitable for honing deep holes. The honing head, which is horizontally positioned, does not rotate and only performs axial reciprocating motion. The workpiece is rotated by the main shaft, and the center frame, which supports the workpiece, and the guide frame, which supports the honing rod, are located in the middle of the bed. During the machining process, the oil stone of the honing head performs radial feed under the action of the expansion and contraction mechanism, gradually machining the workpiece to the required size.

[0003] The existing honing machine connects the honing head and the main shaft directly through a chuck and a connecting rod, and then uses a jack or a screw to fix them to prevent the connecting rod from disengaging during work. However, after long-term operation of the honing machine, the screw is prone to loosening, which causes instability in the connection between the honing head and the main shaft and increases the risk of the honing head disengaging. Therefore, a device for preventing the disengagement of a chuck and a connecting rod of a honing machine is proposed. SUMMARY
