Main shaft capable of blocking nozzle and working method

Abstract

The invention relates to the field of machining, in particular to a main shaft capable of blocking a nozzle and a working method. The main shaft capable of blocking the nozzle comprises a main shaft body, a plurality of spraying heads, a plurality of bases and a plurality of cover bodies, wherein a plurality of limiting blocks are fixed on the outer side walls of the bases, and the thicknesses of the limiting blocks are gradually increased in the direction close to the main shaft body; the cover bodies can cover the bases to block the spraying heads, limiting grooves matched with the limiting blocks are formed in the inner side walls of the cover bodies, a plurality of poking blocks are hinged to the outer side walls of the cover bodies, and the poking blocks extend into the corresponding limiting grooves; and when the cover bodies are closed, the limiting blocks can be clamped into the limiting grooves, and the poking blocks are pushed to rotate anticlockwise. When cooling liquid is introduced into the spraying heads, the poking blocks are poked clockwise, so that the poking blocks push the limiting blocks to be disengaged from the limiting grooves, the situation that splashed chippings are back flushed into the spraying heads to block the spraying heads in the workpiece machining process is avoided, it is guaranteed that the spraying heads can be unblocked in the using process, and the cover bodies can be rapidly disassembled through the arrangement of the poking blocks.

Description

technical field [0001] The invention relates to the field of machining, in particular to a main shaft capable of blocking a spout and a working method. Background technique [0002] Chinese patent, the application number is CN202020340697.8, the application date is 2020.03.18, the publication number is CN211914231U, and the authorized announcement date is 2020.11.13. It provides a high-pressure cleaning nozzle of a scavenger, which belongs to the surface removal or cleaning technology using high-pressure water field. To solve the problems of large oil damping volume, low speed and insufficient lubrication of magnetic damping bearings in the prior art, the technical solution adopted: includes a shell, a coupling body, a small sealing rod, a spray head, a rotating spindle, and a nozzle. The shell is The shape of a hollow cylinder, the nozzle extends into the housing, and is set on the bottom of the rotating main shaft, the rotating main shaft is provided with a pipeline, the ...

AI Technical Summary

Problems solved by technology

[0003] Among them, although the scavenger high-pressure cleaning nozzle solves the problems of large oil damping volume, low rotation speed and insufficient lubrication of the magnetic damping bearing in the prior art, but in the process of use, because the nozzle is always in the open state, when the nozzle is not When working, the debris generated during the processing will recoil into the nozzle and block the nozzle
