Problems solved by technology

For small factories that do not have machine tools such as CNC machining centers, the traditional method is to use pointed-shaped forming tools to forcefully broach the oil groove on ordinary lathes. During processing, the copper bearing bushing is clamped on the three-jaw chuck of the lathe head. The main shaft is locked and does not rotate (that is, the work

Abstract

The invention relates to method for processing oil grooves in inner bores of a copper bearing bush through a common lathe, which comprises the following steps: (1) fixing the copper bearing bush in a fixture body, and fixing the fixture body on a tool rest of the lathe; (2) inserting one end of an auxiliary positioning support tool into a Morse taper hole of a tail rack sleeve of the lathe, and processing a cutter arbor hole at the other end thereof; (3) passing a cutter arbor fixed with a blade through the copper bearing bush, clamping one end thereof on a lathe head, and extending the other end thereof into the cutter arbor hole; (4) starting the lathe to rotate the cutter arbor, moving the tool rest of the lathe, setting the starting position and depth of an oil groove, and flexibly processing the oil groove in the length; and (5) after the first oil groove is finished, retreating a tool bit, stopping the lathe, loosening a fastening piece, rotating the copper bearing bush 180 degrees in the fixture body, fixing the copper bearing bush, and repeating the step (4) to process the second oil groove. The method can be used for processing the oil grooves in the inner bores of the copper bearing bush through the lathe, the cutting force is small, high processing quality and production efficiency can be realized, and a requirement of mass production is met.

Description

technical field [0001] The invention relates to a method for processing an oil groove in the inner hole of a copper bearing bush with a common lathe, in particular to a method for processing the oil groove in the inner hole of the copper bearing bush with a tool and a fixture on a common lathe. Background technique [0002] There is a copper bearing bush on the machine such as image 3 , Figure 4 As shown, there are two oil grooves on the wall of the inner hole. For small factories that do not have machine tools such as CNC machining centers, the traditional method is to use pointed-shaped forming tools to forcefully broach the oil groove on ordinary lathes. During processing, the copper bearing bushing is clamped on the three-jaw chuck of the lathe head. The main shaft is locked and does not rotate (that is, the workpiece does not rotate), and the pointed knife is driven to broach the required oil groove through the longitudinal feed of the large carriage. However, the pr...
