Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a fastening tool for multi-sleeve drilling processing. Background Art

[0002] Self-lubricating bearings are divided into composite material self-lubricating bearings, solid inlaid self-lubricating bearings, bimetallic material self-lubricating bearings, and special material self-lubricating bearings. Different self-lubricating bearings are selected according to different uses and working conditions. Among them, solid inlaid self-lubricating bearings have the characteristics of high load capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are particularly suitable for heavy loads, low speeds, reciprocating or swinging situations where lubrication and oil film formation are difficult, and they are not afraid of water flushing and other acid erosion and erosion. In the processing process of the self-lubricating sleeve of the solid inlaid self-lubricating bearing, it is necessary to drill the surface of the sleeve and then fill the holes of the sleeve with solid lubricants such as inlaid graphite. The properties of graphite are used to make the sleeve self-lubricating.

[0003] In the drilling process of the shaft sleeve, the shaft sleeve itself is generally fixed by a three-jaw chuck on a lathe processing center, and then the hole is drilled by a milling cutter. Although the processing accuracy is high and the processing speed is fast, the operator still needs to manually replace the shaft sleeve after the processing is completed. After the new workpiece is fixed, the processing center needs to be repositioned. Therefore, a considerable part of the processing time is consumed in the material replacement link, which reduces the overall processing efficiency and increases the processing cost. There is room for further improvement. Utility Model Content
