AI Technical Summary

Technical Problem

During the boring pin processing, the boring bar heats to expand due to frictional heat, which may cause the boring bar to lock, affecting the processing accuracy and efficiency.

Method used

A boring bar support device is designed, including a support sleeve, an end cover, an oil inlet passage and an oil outlet passage, through which lubricating oil is delivered to the contact interface between the boring bar and the support sleeve, forming an oil film and reducing friction.

Benefits of technology

It effectively reduces the risk of heat expansion and locking of the boring bar, and improves processing accuracy and efficiency.

Abstract

The utility model provides a boring bar supporting device, and particularly relates to the field of machining. The supporting device comprises a supporting sleeve, an end cover, an oil inlet channel and an oil outlet channel. The supporting sleeve is arranged on a boring rod in a sleeving mode, the end cover is fixedly arranged on the end face of the supporting sleeve, the oil inlet channel is arranged on the supporting sleeve in the radial direction of the supporting sleeve, and an outlet of the oil inlet channel faces the contact interface of the supporting sleeve and the boring rod; the oil outlet channel is arranged on the end cover in the radial direction of the end cover, and the oil outlet channel is communicated with the oil inlet channel. When the supporting device is used, lubricating oil is conveyed to the contact interface of the boring rod and the supporting sleeve from the oil inlet channel, the lubricating oil flows in the axial direction of the boring rod, an oil film is formed on the surface of the boring rod, and friction between the boring rod and the supporting sleeve is reduced.
