Self-lubricating shaft machining lathe

Abstract

The invention discloses a self-lubricating shaft machining lathe, which comprises a lathe body, a spindle box, a chuck, a tool rest, a longitudinal feed device, an oblique feed device and a positioning sensor, wherein the chuck comprises a chuck body; the right end of the chuck body is coaxially provided with a bulgy clamp buckle part; a positioning hole is formed in the chuck body; a positioning groove is formed in the positioning hole; the clamp buckle part is provided with a fixing hole which is coaxial with the positioning hole; a positioning sleeve is arranged in the positioning hole in a matched manner. By an annular pressure oil tank structure formed in the chuck body, pressure borne by an annular pressure spring is utilized to control the oil pump capacity of coolant oil in the pressure oil tank, the technical goal of accurate oil pumping is achieved, and the surface roughness of shaft parts is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a self-lubricating shaft processing lathe. Background technique [0002] During mechanical processing, it is often necessary to use a lathe to process shaft parts. In the processing process of existing lathes, the main chucks are mostly simple three-jaw chucks, and their concentricity is poor. Therefore, when processing long shaft parts During processing, the radial position of the part will be offset during the turning process, resulting in poor concentricity and rough surface of the part after machining. For the technical problem of rough surface, another reason is that during the cutting process of the lathe, the contact between the tool and the part generates high temperature, which will cause the deformation of the surface of the tool and the part. Nowadays, coolant is generally used for spray cooling. It is a water cooling process. The cooling effec...

[0002] During mechanical processing, it is often necessary to use a lathe to process shaft parts. In the processing process of existing lathes, the main chucks are mostly simple three-jaw chucks, and their concentricity is poor. Therefore, when processing long shaft parts During processing, the radial position of the part will be offset during the turning process, resulting in poor concentricity and rough surface of the part after processing

For the technical problem of relatively rough surface, another reason is that the contact between the tool and the part during the cutting process of the lathe generates high temperature, which will cause the deformation of the surface of the tool and the part. Nowadays, coolant is generally used for spray cooling. It is a water cooling process. The cooling effect of water cooling is not significant due to the low boiling point of water. The best cooling oil is cooling, but the price of cooling oil is high. The traditional external spraying technology is obviously not acceptable to enterprises.
