Description
Technical field
The invention belongs to field of mechanical technique, relate to one and unload knife system, particularly the lathe such as a kind of drilling machine, tapping machine unload knife system.
Background technology
Drilling machine refers to mainly use the lathe of drill bit machining hole on workpiece.Conventionally bit is main motion, and drill bit moves axially as feed motion.The feature of drilling machine is that workpiece maintains static, and cutter rotates, and along major axes orientation feeding, operation can be manually, can be also motor-driven.
Existing drilling machine, for example Chinese patent literature data discloses bench drill [application number: 201210219151.7; Granted publication number: CN 103506646 A], it comprises base, be carried on Upright post base on base, be carried on column on Upright post base, be installed on the workbench moving up and down on column and along column, the main spindle box that is installed on column top, motor, be installed on the cutter of main spindle box lower end, is positioned at electromagnetic switch and motor change-over switch on main spindle box front surface.
The drilling machine of this kind of structure, Cutting tool installation manner is in chuck, and the taper shank of cutter is fixed in the Morse taper hole of main shaft, need to change cutter time, uses iron hammer to knock to unload cutter iron and unloads cutter, makes the taper shank of cutter be knocked and depart from main shaft, thereby reaches the object of unloading cutter.Use this kind of method to unload cutter, while knocking, waste time and energy, and easily damage chuck, main shaft and cutter.
Such as tapping machines of other lathe etc., rotate the lathe of processing by main shaft band cutter, also have similar problem in the time unloading cutter.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide a kind of drilling machine to unload knife system, solve how to make the similar lathes such as existing drilling machine unload cutter laborsaving, and the problem that can not damage such as cutter.
Object of the present invention can realize by following technical proposal: a kind of drilling machine unloads knife system, drilling machine comprises main spindle box and feeding handle, in described main spindle box, be provided with main shaft, it is characterized in that, axially there is along main shaft in described main shaft the installing hole running through, described main shaft is connected with the power transmission shaft of axial restraint, and one end of power transmission shaft is located in the installing hole of main shaft, describedly unload the sleeve that knife system comprises that position limiting structure and spindle jacket have, axially there is spur rack along sleeve on the lateral wall of described sleeve, described spur rack is connected with feeding handle, described main shaft moves up and down with sleeve, described position limiting structure is positioned at the top of sleeve and can moves on the mobile route of sleeve.
The bottom of spindle mounting hole is a taper hole, and top is circumferentially connected with power transmission shaft, and cutter is connected in taper hole, when work, position limiting structure is positioned at the top of sleeve and on the mobile route of sleeve, in the time that sleeve is encountered position limiting structure, and the now peak of sleeve in the time of normal process; In the time that needs are changed cutter, control position limiting structure, make position limiting structure leave the mobile route of sleeve, by swivel feeding handle, sleeve is moved up, position limiting structure is crossed at the top of sleeve, main shaft is with moving on sleeve, now the afterbody of cutter impinges upon the top of power transmission shaft, and cutter comes off automatically from the installing hole of main shaft, reaches the object of unloading cutter.Use the lever principle between feeding handle and sleeve, unloading cutter only needs less strength to complete, time saving and energy saving, and can not damage cutter, main shaft etc., after unloading cutter and completing, swivel feeding handle moves down sleeve, controls position limiting structure, makes position limiting structure re-move the top of sleeve and on the mobile route of sleeve.
