Abstract
The utility model relates to a tool quick changing device, which comprises a tightening screw and a facing cutter with a taper-shank, wherein roller pins are arranged in blind holes of the facing cutter; a locking sleeve with a spring is respectively installed on two sides of the facing cutter; and the locking sleeve is engaged with a steel ball to limit a connecting sleeve to move forwards and backwards. A roller pin limit groove positioned at the tail end of the connecting sleeve is engaged with the roller pins to limit the connecting sleeve to rotate, thereby a tool on the connecting sleeve is capable of being tightly fixed and the tool quick changing device is simple and convenient to be installed and disassembled.
Description
Technical field
The utility model relates to a kind of cutter changing device, particularly a kind of fast replacing device that multiple cutter can be installed in the engine lathe spindle hole.
Background technology
The mounting cutter of operating personnel in the spindle hole of engine lathe waits to finish as milling cutter, drill bit, screw tap Cutting Parts processed.The installation of cutter mainly is the extension bar that matches with the lathe spindle taper hole by at present, and in the rear end of lathe spindle, the taper hole of its front end processing part is used for loading and unloading cutter with the extension bar tension.So whenever, finish cutting process one, operating personnel must constantly repeat following operation: slowly lathe spindle is forwarded to taper shank and unload the groove position, take wedge to aim at taper shank then on the other hand and unload groove, another hand knocks wedge with iron hammer cutter is unloaded, and other cutters is installed is again entered next procedure.
This traditional structure has been wasted a lot of times and manpower when the installing/dismounting cutter, working (machining) efficiency is not high.
Summary of the invention
The purpose of invention of the present utility model overcomes above-mentioned weak point exactly, and knife quick change device a kind of simple in structure, easy to operate is provided.
The technical solution of the utility model is as follows: a kind of knife quick change device, be used to cooperate the lathe spindle hole to use, comprise the stretching screw that is connected with the lathe spindle hole, the facing cutter that has taper shank that is connected with stretching screw, facing cutter is the cylinder that has blind hole with respect to the other end of taper shank, be provided with vertical needle roller in centre position, blind hole bottom, be provided with in the both sides in cylinder stage casing and become two taper holes of 90 ° with needle roller, steel ball is housed in the taper hole, be outside equipped with lock sleeve at cylinder, between cylinder and lock sleeve, also be provided with stepped hole, spacing back-up ring and spring are housed in the stepped hole, the lock sleeve tail end is provided with horn mouth to the part of taper hole, be provided with the adapter sleeve that is used for mounting cutter in the blind hole, the adapter sleeve tail end is provided with at least two needle roller link slots that cooperate needle roller to be used to drive the adapter sleeve rotation, is provided with the steel ball stopper slot that cooperates steel ball in the both sides of adapter sleeve.
Described taper hole is a small end near an end of steel ball stopper slot, and small end opening part diameter is less than steel ball, and taper hole is big end near a bell-mouthed end, and big end opening place diameter is greater than steel ball.
Described steel ball stopper slot is shallow annular groove.
The needle roller stopper slot of described adapter sleeve tail end can be 4, respectively establishes one at the two ends of adapter sleeve tail end vertical direction, and two ends are in the horizontal direction respectively established one.
The utility model cooperates steel ball to limit moving forward and backward of adapter sleeve by the lock sleeve that has spring, when mobile lock sleeve compresses spring, horn mouth has been given the steel ball activity space, and steel ball can break away from the steel ball stopper slot on the adapter sleeve, makes things convenient for the quick loading and unloading of cutter.Unclamp lock sleeve, steel ball is locked to overlap and is pressed into the steel ball stopper slot.Needle roller link slot by the adapter sleeve tail end cooperates needle roller to drive the adapter sleeve rotation, can well drive the cutter rotation on the adapter sleeve, and load and unload simple and convenient.
