Abstract
The utility model relates to a milling and boring head, wherein a main spindle box and a base are connected by a rectangular guide rail pair, the base is provided with a screw-nut pair and a driving motor, the driving motor is connected with and drives the screw-nut pair so as to lead the main spindle box to move axially on the base, and the main spindle box is internally provided with a speed-change mechanism and a main spindle component; the milling and boring head has wide applicability, can be used for processing planes and holes of black metal and nonferrous metal parts, can be equipped on various processing machine tools for use as a modularized cutting functional component, and is applicable to industries such as mechanical manufacture, metallurgy, mine, shipbuilding and the like, and can be applied to various processing machine tools as a main spindle functional component.
Description
Technical field
The utility model relates to a kind of milling and boring heads.
Background technology
To be lathe directly drive the spindle unit that cutter carries out plane and hole processing adding man-hour to milling and boring heads, not only rotates but also do axially-movable.Its performance directly influences crudy and rate of cutting output, is the key factor of decision machine tool capability and economic and technical norms.
All it was considered as certain specific machine tool spindles when milling and boring heads designs in the past that its motion will realize by additional motion parts on the lathe, and be subjected to structural limitations, do not have interchangeability, can not be applied on other lathe.
The utility model content
The purpose of this utility model provides a kind of independently milling and boring heads, and it can overcome the deficiency that above-mentioned prior art exists, and is applied to various machining tools as the main shaft functional part.
The purpose of this utility model realizes by following technical measures:
A kind of milling and boring heads, comprise base, main spindle box, main shaft, be installed in the main motor on the main spindle box, members such as drive motors, gas-operated lock cutter mechanism and rotation handwheel, it is characterized in that: adopt the secondary connection of rectangular guideway between main spindle box and the base, said base is provided with feed screw nut pair and drive motors, the clutch end of drive motors connects and drives feed screw nut pair moves axially main spindle box on base, gear and spindle assemblies are housed in main spindle box.
Described gear comprises by two three grades of shifting slide gear speed change transmission groups of main driven by motor and gear change hand lever.
Described spindle assemblies comprises bearing on the main shaft that is connected the broaching tool screw front end and the broaching tool screw rod and the parts such as travelling gear that link to each other with gear, and the broaching tool screw rod other end is connected with the gas-operated lock cutter mechanism.
Described rotation handwheel connects and drives feed screw nut pair makes main spindle box axially micro-moving on base.
The milling and boring heads power that the utility model provides is big, the stock-removing efficiency height, and under the situation of volume, similar weight, motor power (output) is than the big twice of traditional milling and boring heads.
The milling and boring heads that the utility model provides has high rigidity and high strength, during axial feed, is that rectangular guideway connects and realization is moved between main spindle box and the base, realizes that by rack sleeve is flexible axial feed has higher rigidity than traditional milling and boring heads.
The milling and boring heads applicability that the utility model provides is wide, can be used for the plane and the hole processing of ferrous metal and non-ferrous metal part; Be installed on the various machining tools as modular cutting functional part and use, be applied to industries such as machine-building, metallurgy, mine, shipbuilding.
