A kind of miniature bearing ring processing lathe

Abstract

The invention discloses a lathe for processing a miniature bearing ring. The miniature bearing ring processing lathe comprises a lathe bed, a spindle, a motor used for driving the spindle to rotate, an adjustable motor bracket for installing a motor, a material receiving mechanism, an automatic feeding mechanism and a carriage mechanism, wherein the automatic feeding mechanism is provided with a keep-off device, so that the defect that in the prior art blank is easy to block, the production continuity is poor and the control system is more complex of the automatic feeding mechanism are overcome; by adopting an oblique feeding carriage, the defects that in the prior art the carriage plate mechanism needs to perform longitudinal feeding first, and then perform transverse feeding, so the structure is more complex and the impact of the cutting tool relative to a workpiece is larger during the processing of sleeve-type products are overcome; by adopting the material receiving mechanism, the defects that in the prior art uncertain phenomena of flatly falling, tilting and the like the miniature bearing ring when the miniature bearing ring falls into a rough occur, so that the trough is easily blocked up, and the like are overcome; by means of the spindle structure, the workpiece can be clamped fast, and the radial size of a clamping device is smaller.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a lathe for processing miniature bearing rings. Background technique [0002] In lathe processing, its loading is mainly divided into two methods: manual and automatic. Due to the low efficiency of manual loading, it is rarely used in modern production. There are many ways of automatic feeding, each with its own advantages and disadvantages. For example, the Chinese invention patent with the application number "201010119959.9" discloses an automatic feeding device for a CNC lathe, which is mainly driven by a hopper installed on the bedside box, and the hopper controlled by the driving device is installed on the horizontal slide of the lathe. It is composed of the ejector on the top and the spindle clamping device installed on the spindle of the CNC lathe. The defective of above-mentioned technical scheme is: [0003] First of all, the hopper in the patented technical solut...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a special-purpose lathe for processing miniature bearing rings, which overcomes the problems of blank congestion, poor production continuity, complicated control system and the need for processing sleeve products in the prior art. The carriage structure feeds longitudinally first, and then feeds horizontally, resulting in a more complex structure and a greater impact on the tool relative to the workpiece. When the miniature bearing ring falls into the trough, there will be uncertain phenomena such as flattening and tilting, resulting in Prone to congestion and other defects
