Description
Technical field
The present invention relates to field of machining, is knife sharpener automatic withdrawal chuck.
Background technology
Knife sharpener has omnipotent sharpening and numerical control knife sharpener, and these knife sharpeners are in dress knife and to unload knife be all manually to complete,
Particularly when exiting cutter, collet is held tightly cutter holder, when manually taking out cutter with hand, it has not been convenient to, or even taking out
When blade easily cut wound worker hand.In order to overcome the shortcomings of existing sharpening machine grip holder, spy provides a kind of following retraction mechanism and come
Solve the above problems.
The content of the invention
The present invention is to provide knife sharpener automatic withdrawal chuck, and it is that following scheme is realized, as illustrated, in collet
Clamping position set a push rod, push rod diameter is smaller than the clamping diametric hole of chuck, and the small end behind push rod is equipped with round wires bullet
Spring, push rod is extruded forward by wire spring all the time in the presence of wire spring.After cutter loads collet, push rod pressure
Drawn back while contracting wire spring, after tool blade milled, when unclamping clamping force, wire spring, which is upspring, promotes push rod cutter
Release the clamping position of collet.Knife sharpener automatic withdrawal chuck, it is characterized in that：It is by collet (125), push rod
(135), push rod splicing sleeve (145), adjusting nut (155), trip bolt (165), wire spring (175) are formed, the spring
Push rod (135) is provided with the hole of chuck (125), the diameter of push rod (135) front end is bigger than the diameter of rear end, push rod (135) front end
Diameter it is smaller than the bore dia of collet (125), push rod (135) rear end is equipped with wire spring (175), wire spring (175)
Push rod splicing sleeve (145) is withstood in one end, and the other end is withstood on the step surface of push rod (135) front-end and back-end junction formation, top
The rear end of bar (135) slides through push rod splicing sleeve (145), and push rod (135) rear end is provided with screw thread, push rod (135) rear end
Connection is engaged into screw thread with adjusting nut (155), the front end face of adjusting nut (155) is close to push rod splicing sleeve (145), described
Push rod splicing sleeve (145) is fastenedly connected in the hole of collet (125) rear end with trip bolt (165).Knife sharpener moves back automatically
Cutter holder head, its advantage are：It is not only suitable for knife sharpener and automatically exits from cutter, at the same it be adapted to bench lathe, engine lathe,
Numerically controlled lathe, omnipotent vertical milling automatically exit from cutter or automatically exit from workpiece, and its reliable in action is simple in construction, can standardize
Production supply lathe support the use.Knife sharpener automatic withdrawal chuck, it is inconvenient during existing knife sharpener withdrawing to solve, Gong Renlao
The problem of fatigue resistance is big.Solves the problems, such as blade easy cut wound worker hand during existing knife sharpener withdrawing.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings
Shown in figure：
Fig. 1 is the construction connection figure of the present invention
Fig. 2 is the cutter or workpiece of the present invention
Digital number represents respectively in figure：
125- collet 135- push rod 145- push rod splicing sleeves
155- adjusting nut 165- trip bolt 175- wire springs

Embodiment：
Knife sharpener automatic withdrawal chuck is illustrated as, the construction connection of the mechanism and operation principle are made specifically below
It is bright：
First, construction connection：Knife sharpener automatic withdrawal chuck, it is characterized in that：It by collet (125), push rod (135),
Push rod splicing sleeve (145), adjusting nut (155), trip bolt (165), wire spring (175) are formed, the collet
(125) push rod (135) is provided with hole, the diameter of push rod (135) front end is bigger than the diameter of rear end, push rod (135) front end
Diameter it is smaller than the bore dia of collet (125), push rod (135) rear end is equipped with wire spring (175), wire spring (175)
Push rod splicing sleeve (145) is withstood in one end, and the other end is withstood on the step surface of push rod (135) front-end and back-end junction formation, top
The rear end of bar (135) slides through push rod splicing sleeve (145), and push rod (135) rear end is provided with screw thread, push rod (135) rear end
Connection is engaged into screw thread with adjusting nut (155), the front end face of adjusting nut (155) is close to push rod splicing sleeve (145), described
Push rod splicing sleeve (145) is fastenedly connected in the hole of collet (125) rear end with trip bolt (165).
2nd, operation principle：When needing to sharpen cutter or workpieces processing (185), cutter or workpiece (185) are loaded first
In the hole at the clamping position of collet (125), the then retaining mechanism fastening spring chuck (125) of lathe, collet
(125) due to the clamping force by locking mechanism for machine tool, then while collet (125) clamp-on tool or workpiece (185),
The rear end of cutter or workpiece (185) promotes push rod (135) compression wire spring (175), push rod (135) also retraction backward, lathe
Retaining mechanism continues locking spring chuck (125), and at this moment collet (125) is acted on by locking mechanism for machine tool coupling mechanism force, is made
Its collet (125) clamp-on tool or workpiece (185), after cutter or workpiece (185) clamping, just start to sharpen cutter or add
Work workpiece, after cutter or good work pieces process, locking mechanism for machine tool is at this moment unclamped, in this release process, collet (125)
Coupling mechanism force is lost, in the moment for losing coupling mechanism force, wire spring (175), which is upspring, promotes push rod (135) cutter or workpiece (185)
Released from the hole of collet (125).
