Description of the invention: [Technical field to which the invention pertains] The present invention belongs to the mechanical field of a tool change mechanism - a clamp member provided on a tool change arm: in the case of a body, a knife is then extended and then extended Make the knife 曰 ^ ^ ^ away from the front of the knife, you can hold the knife bar silently. 'The knife will not hit the clamp during the knife. [Previous technique] The integrated processing machine sets the tool change mechanism (atc to the spindle, and performs various kinds of work libraries on the workpiece. The various types are shown in the first and second figures. It is in the machine setting month = the mechanism (four) knife, the backward knife and the rotation == change =, in the tool change arm (12), the knife bar (9) that holds the tool holder is locked, and the "Kata" sound is generated. 'This sound is derived from the shank (, disk) 扣 邛 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 Under the restriction of the groove (23), the clamp member (20) which is often t will be stretched toward the front of the buckle portion ((4) by the spring (24). Thus, whether it is a knife or a knife change, the cutter bar (13) )) strikes the head (21) of the clamping member (20), and then emits an impact sound. ^In the past, 'long-term, except for the sound, the members that collide with each other are also prone to loss. In order to solve the lack of prior art, the present invention develops a blade arm silent buckle knife, which is one of the purpose of creation: the clip piece is buckled in the buckle process In front of the part, after the shank enters the knives, the clamping element extends 200936305 • to support the arbor. With the rotation of the changing arm, the knives are matched with the clamps to execute the deduction shaft. Therefore, the knife (4) does not cause disturbing rafts, and is free from impacts between the components, reducing the loss between the components. To achieve the above purpose, the present invention is a blade arm silent knives a top arm, a sleeve provided with an elastic member, and two elastic tops, and a side of the clamping member adjacent to the top member is provided with an elastic two (four) abutting portion, the replacement Each end of the knife arm has a buckle-a groove. The groove-side communication buckle portion opening == another side communication-cavity. The clamp member is placed in the corresponding groove, and a slap has a top abutting portion.

At the end (31) (two = with - tool change arm (3)), the tool change arm (33) is clamped to the opening direction phase of 4); each == = the mouth of the mouth is assembled with an elastic clamp The piece (2!, telescopic in the tool changer arm (33), after the tool holder is pulled out" 4 is in front of the buckle knife part (34) to support the knife bar. 4 6 200936305 Knife #个件 〇4〇) Mainly At the time when the knife is not buckled, the mode of retracting and changing is adopted. (4) After the knife is buckled, it is extended to support the cutter bar ε. The main feature of the two ί f is that after the knives are fully extended, the knife is knives when the knife is buckled. The power generated after the impact of the rod causes a recess 〇 5) at each of the adjacent two knives (34) into which the clamping member (10) is retracted, and each groove is tightly swelled to the base portion. ), the two ends of the groove respectively lead to the knives (the opening, and the recess (37) for accommodating the top member (43), and in the groove ί: = = 36), the groove (35) accommodates the clamping member After (4〇), seal the top of the trough' and the central part (then by the bomb) Element: the end resists the base (38) on the pair (33). (Of course, the base (38) also replaces the area of any position where the force can be applied on the arm (33). The other end is abutted against the top abutting portion (48) of the gripping member (40), and elastically acts on the changing arm (33) and the clip by the force and reaction force characteristics of the elastic member (41). The abutting portion of the jaw member (40) (therefore the jaw member (40) will be displaced rearwardly by the elastic force, causing the tip end (42) of the jaw (40) to retract into the slot. Viewed from the drawing, the gripper member (40) is composed of a main body (45) screw-long rod (46). The main body (45) has a recessed portion (47)' covering the restriction % for limiting the displacement amount of the clamping member (4) adjacent to the top abutting portion of the long rod (46) locked at the end (44) ( = The end surface of the nut shown in the figure can also be the ring surface of the _ c-type fastener, or it can be - the end surface of the active edge, allowing the elastic ^ (41) to be worn over the shaft Between the top abutting portion (48) and the rear member (40) is displaced backwards. 诔 诔 200936305 = 参 _ 3 and the fourth figure, the case is in the case of the unknuckled knife 1 = (32) and The corresponding relationship between the tool changing arms (33): == the top end of the elastic jacking member (43) in the recess (37), just maintaining the end face 'making the top member (43) act And the class position 'Because the diameter of the upper edge of the top filial piece (43) is small, the elastic section (41) is elastic, and the top element is moved to the top and then continues to maintain the resistance to the top. Pieces (43), ❹ Ο 1 (34f (4G) front end is retracted into the tool changer arm (33), and the knives are removed from the knives and can be prevented from colliding with the arbor.
