Description

Knife arm integrated silent knife

The invention is a kind of knives, in particular a knives and arms integrated silent knives, which are arranged by a pin in a guiding chute to reciprocate a knives in a reciprocating motion of an urging member. One of the rods protrudes or retracts into a slot to resist or release the circumference of a tool; the retracted state avoids impact and sound of the blade cone during the tool change. The tool circumference has been engaged, that is, it protrudes against the tool.

The conventional buckle arm is used to replace the tool to the machining spindle. However, during the replacement process, the buckle lever and the cutter are engaged to produce a "click" sound; the other side of the cone has a spring as a returning elastic preload; During the process of knives, the taper of the knives is contracted by the squeezing of the knives. After the squeezing is completed, the taper of the knives is ejected by the elastic preload force, causing metal impact sounds, which may cause wear of the knives and the knives. With deformation.

Therefore, in response to the above problems, the creator conceived how to develop an innovative paper structure that is more ideal and practical. It is really eagerly awaited by consumers, and it is also the goal and direction of relevant industry players to work hard to develop breakthroughs.

This creation is intended to solve the problem of wear, deformation and damage caused by the elastic collision of a blade taper with a tool.

The present invention provides a knife-arm integrated silent buckle knife, which comprises at least: a tool change arm, wherein two ends of the cutter arm are respectively provided with a reverse concave curve, and the two sides of the central axis of the tool change arm are respectively axially arranged. a chamber, and a slot is respectively recessed on both sides of the top surface of the tool change arm, and the slot communicates with the blade edge to the chamber, and the abutment portion of the chamber and the slot is recessed to form abutting portion The two vertical actuating portions respectively have an actuating member and a latch; the actuating member is disposed in the chamber, the top end is provided with a protruding rod, the bottom end is provided with a groove, and a convex portion is disposed toward the side of the buckle edge; The top of the top seat is provided with a continuous perforation, the through hole is formed in the protruding rod, the bottom surface of the top seat is locked to the top surface of the chamber by a plurality of screws; a base is locked to the bottom surface of the chamber by a plurality of screws; a first elastic member abuts between the groove and the base to provide a resilient pre-stress of the actuating member; the convex portion defines a guiding chute radially, and a guiding chute is respectively disposed at each end of the guiding chute a top extension end and a bottom extension end, the top extension end is higher than the bottom extension end, and the top extension Adjacent to the central axis of the tool change arm, the bottom extending end is adjacent to the buckle edge; the two fastening knife bars are respectively disposed in each of the slots, and comprise: a shaft body, and the buckle blade portion is provided at one end a lug portion is disposed on each of the two sides of the other end, and a receiving groove is defined in the top surface; the receiving groove is provided with a stopper and a second elastic member, and the two ends of the second elastic member respectively abut the stopper And the inner wall surface of the accommodating groove, the block is fixed to the inner surface of the slot by a screw; each of the lug portions is provided with a through hole for each of the latches to be pivotally connected to the guiding chute, so that The knives are formed in a reciprocating relationship with the guiding chute, so as to achieve the effect of holding the knives and the internal retracting knives; the connecting portions of the lugs and the shaft are provided to correspond to the abutting portions Reach one of the abutments In order to guide and limit the action direction and displacement space of each of the knives; the two bayonet members are respectively corresponding to the concave platform at the top of each of the knives; the two top covers are respectively locked by a plurality of screws Connected to the top surface of the tool change arm as a sealing element for each of the slots.

With the above structure, the knife is not only quiet, but also wear or deformation caused by collision of related components can be avoided to prolong service life and stability.
