New description: [New technical field] This creation relates to a quick-release tool with a replaceable blade, especially a centrifugal quick release tool that achieves the effect of positioning the tool by force: . [Prior Art] Since the cutter is used only when the cutter is partially lost, if the blade is designed to be detachable, not only the cost of the cutter can be saved, but also the replacement of the blade can speed up the replacement. speed. The existing quick release tool, as shown in the sixth figure, is provided with a cutter bar body (5〇) with a round rod p3, and a four-knife blade is vertically recessed between the circumferential surface of the cutter body (50) and the like. The γ-channel sipe (5 1 ), the sipe (5 1 ) is recessed in the side wall to form χΜ ^ ^ R Ο 疋 , 疋 (5 2 ) and the other side wall forms the ratchet 1 ( 5 1 1 ) Each of the fixed grooves (52) has a sloped surface and a bottom surface, and the respective circumferential surfaces of the cutters respectively correspond to the inclined surfaces of the respective #(52), and the screw holes (53) of the four|intervals are respectively inserted inward, and the screw holes of the rows are arranged. The inner end and the fixed groove have: 2) self-passing and respectively provided with eight; inserting blades (54) into each sipe (5 丄), each blade (54) and each sipe (51), Spurs 5 (5 1 1) meshing; a block (5 5 ) is embedded in each fixed slot (52), and a bolt (5 6 ) is screwed to each screw hole (5 3 ), and each screw (5 6) The inner end presses the wedges (5 5 ) and holds the blade (5 to thereby position the blade (54) in the blade (5 1). ^The above-mentioned existing quick release tool can be replaced The head of the blade (5 4 ) (and because it needs to screw eight bolts 56 when installing a blade (5 4 )) Keeping close to the blade (54), meaning to install four blades (54) M3 00153, it is necessary to screw dozens of screws to not only take time and effort. The force of this mounting blade (54)... Applying each bolt (5 fi '迢 on average to the wedge (5 5) causes the module (55) to hold the blade (")): two big problems, easy [new content] (") power imbalance: In the existing quick-release tools, there will be time-consuming and shortcomings in tool installation. For this purpose, the design is a kind of quick-release tool, which is based on the technical means of uneven tool, and the purpose of centrifugal force is tight. The creation of this creation is fast and supportive. All of them are made up of the above-mentioned creations. The system is provided with: , 'This creation department--a kind of centrifugal quick-release knives have two bodies, the cutter body is in the circumferential surface and the like, and each sipe is formed therein - the side wall is concavely formed - Daoding: Each fixed groove has a slanting direction - a duct groove, and a surface is formed, and the outer sides of each of the inclined surfaces extend inward in the direction of each sipe; Each sipe is not formed into a sipe, and each sipe is formed into a slot. The side walls are closely attached; two or more wedge blocks, the wedge side walls of the wedges are slanted against the knives in the respective slots, and the wedges are disposed between the bottom surfaces of the grooving grooves. 'Setting the ejector positioning device as an elastic member and an ejector member including both ends of the groove, each elastic member having a weight = against the bottom surface of the wedge, and another w having a bee 1 · raw > The end abuts against the bottom surface of the fixed slot, and the top M300153 is coupled to the wedge in an adjustable depth manner to abut the bottom surface of the fixed slot at the bottom end. Further, the two ends of the bottom surface of the fixed slot are respectively The recess is provided with a circular groove, and the wedge has a recess corresponding to each circular groove at each end of the bottom surface, and each elastic member comprises two springs and a top block respectively received on the bottom side and the top side of the circular groove, respectively. The spring abuts against the bottom end of the top block, and the top end of the top block protrudes from the circular groove to abut against the groove of the wedge; the wedges are centrally disposed with a screw hole, and the ejector member is A bolt 'locks to the screw hole and the bottom end abuts against the bottom surface of the slot. Preferably, the circumferential surface of the cutter body is provided with four sipe, each sipe is a U-shaped groove and the direction of the adjacent sipe recessed is perpendicular to each other, and the inclined surface of the fixed groove is opposite to the blade The bevel is a long-shaped dovetail block. This creation uses the rotation of the tool body on the spindle of the machine tool. Because the spindle speed of the machine tool is extremely high, the wedge can be moved outward by the centrifugal force generated by the high speed, so that the wedge is fixed. The slope of the groove faces outward and slides in the direction of the blade to press the blade, and when the rotation speed of the tool body is higher and the centrifugal force is larger, the force of the wedge holding the blade is larger, so that the blade can be reliably positioned when the high rotation speed is actuated. In the sipe without pulling out 'to achieve a true positioning effect. When the creation is to change the blade, the damaged blade can be taken out to replace the new blade by simply moving the wedge into the bottom of the groove. When the new blade is inserted into the sipe, the ejector positioning device will be used. The wedge is ejected outwardly and the blade is clamped to complete the installation. M300153 The structure of this creation can achieve the following effects: 1. Because the creation mainly uses the centrifugal force generated by the high rotation speed to make the mold 4 close to the clamping blade, the holding force can not only increase with the rotation speed but also maintain the average force, which can be positioned. blade. 2. The blade does not need to be tightened with a large number of bolts when installing the blade. The structure of the blade replacement is simple and convenient to use, which makes the creation have the advantage of quick installation.
