Numerical control machining spindle box

Abstract

The invention discloses a numerical control machining spindle box and belongs to the field of spindle boxes, the numerical control machining spindle box comprises a box body and an inner shell, a rotatable inner shaft is mounted in the inner shell, an annular groove with an opening in the bottom is formed in an interlayer between the box body and the inner shell, and a plurality of feeding shells used for sucking crushed materials are mounted in the annular groove; a through hole is formed in the center of the inner shaft and communicated with the mounting hole, an arc-shaped hole is formed in the inner shaft and located on the outer side of the through hole, the two ends of the arc-shaped hole are communicated with the through hole, a plurality of steel balls are distributed in the arc-shaped hole, and annular grooves matched with the steel balls are formed in the side wall of the fixing rod. According to the device, waste generated after machining can be sucked from the workbench and discharged to the outside, the multiple feeding shells are arranged, feeding can be conducted from multiple directions at the same time, cleaning is more thorough, the possibility of dead angles is reduced, the fixing rods are expanded outwards through the conical columns, the fixing rods are clamped through the steel balls in the expanding process, and a cutter is fixed.

Description

Technical field [0001] The present invention relates to a CNC machining spindle box, belonging to the field of spindle housing. Background [0002] Milling machine is the use of high-speed rotating milling cutter, the material slotting, tenoning and processing out of the forming surface of the machine tool, non-metallic processing processing, first of all, the soft texture of non-metallic materials generally do not need to use cutting fluid, followed by processing produced more chips, often in the workbench and the ground to leave more waste, when the waste is more, workers can not observe the shape of the cutting product, affecting the follow-up work, the spindle in the work, the spindle drives the tool to rotate at high speed, in the process of tool rotation, In order to reduce friction, the contact with the rotating shaft is minimized, and the actual machine tool friction is larger, and the service life of the spindle is shorter. Contents of the Invention [0003] In view of ...

AI Technical Summary

Problems solved by technology

[0002] A milling machine is a machine tool that uses a high-speed rotating milling cutter to slot, mortise, and process a forming surface. There is a lot of waste, which often leaves a lot of waste on the workbench and the ground. When there is a lot of waste, the worker cannot observe the shape of the cutting product, which affects the follow-up work. When the spindle is working, the spindle drives the tool to rotate at a high speed. In the process of rotation, in order to reduce friction, the contact with the rotating shaft will be minimized. The actual machine tool has relatively high friction and the service life of the spindle is short.
