The number of the cutter seat grooves 41 on each cutter seat disk is generally 2-6, so that the requirement on the number of different cutter seats assembled on the same equipment can be met, and the whole installation space and the machining space are kept in a proper range. During design, the angle formed by the tool apron groove 41 and the axis of the fixed disc 2 is the same as the angle formed by the axis of the fixed disc 2 and the axis of the vertical arm 1, and the position of the tool apron groove 41 can be obtained by selecting a proper distance; or the position of the holder pocket 41 is determined directly by rotating the holder disc after the holder disc is designed.
As shown in fig. 4-5, in order to facilitate the installation of the tool holder in the tool holder slot 41 and also facilitate the overall replacement of the tool holder slot 41, the tool holder disc includes a rotating cutting sleeve 3 and a tool holder assembly disc 4; the rotary clamping sleeve 3 is sleeved on the fixed disc 2, rotates around the axis of the fixed disc 2 and is axially fixed with the fixed disc 2, and the tool apron assembling disc 4 is detachably connected to the rotary clamping sleeve 3. During concrete connection, one end face of the rotary clamping sleeve 3 is flush with one end face of the fixed disc 2, and the end face of the rotary clamping sleeve 3 is provided with a screw hole for connection. The cutter holder assembly disc 4 and the rotary clamping sleeve 3 are detachably connected through bolts, so that the cutter holder is convenient to replace or disassemble and overhaul.
Further, the locking structure comprises positioning pins 5 and positioning holes 22, the positioning pins 5 and the positioning holes 22 are respectively arranged on the rotary cutting sleeve 3 and the fixed disk 2 along the radial direction, and a plurality of positioning holes 22 are arranged; when any of the holder grooves 41 is coaxial with the vertical arm 1, the positioning pin 5 is selected to be opposite to the positioning hole 22. The locking between rotatory cutting ferrule 3 and the fixed disk 2 is realized to the cooperation that this embodiment adopted round pin, hole, and the cooperation position of locating hole 22 and locating pin 5 corresponds the coaxial position of corresponding tool holder groove 41 and perpendicular arm 1, and this kind of setting mode restriction and removal restriction convenience to occupation space is little, is suitable for here rotatory cutting ferrule 3 and the locking application of fixed disk 2.
Further, as shown in fig. 6, the locking structure further includes a compression spring 51 for applying pressure to the positioning pin 5 in a direction toward the fixed disk 2, an annular sliding groove 21 coaxial with the fixed disk is formed in a side surface of the fixed disk 2, one end of the positioning pin 5 extends out of the rotating sleeve chuck 3, the other end of the positioning pin is located in the annular sliding groove 21, the compression spring 51 is sleeved outside the positioning pin 5, the rotating sleeve chuck 3 is provided with an installation cavity 31 for accommodating the compression spring 51, and the positioning pin 5 is provided with a force-bearing retaining ring 52; one end of the compression spring 51 is in contact with the force bearing baffle ring 52, and the other end of the compression spring is in contact with the bottom of the installation cavity 31; the positioning hole 22 is located in the annular slide groove 21. When locking, the positioning pin 5 is pressed into the positioning hole 22 by the compression spring 51; when the lock is released, the positioning pin 5 is manually pulled out so that the end portion thereof is positioned in the annular slide groove 21. After the locking is released, the rotary cutting sleeve 3 is rotated, the end part of the positioning pin 5 slides in the annular sliding groove 21, and when the end part reaches the next positioning hole 22, the end part is automatically pressed in by the compression spring 51, and at the moment, the next cutter is just coaxial with the rotary cutting sleeve 3.
Further, in order to facilitate the relative rotation between the rotary cutting sleeve 3 and the fixed disc 2 when unlocked, the rotary cutting sleeve 3 partially wraps the side surface of the fixed disc 2 and the end surface where the vertical arm 1 is located; ball 6 is in addition between rotatory cutting ferrule 3 and the fixed disk 2, all be equipped with the confession on fixed disk 2 and the rotatory cutting ferrule 3 the rolling annular rolling groove 61 of ball 6. The cooperation of the balls 6 and the annular rolling grooves 61 facilitates the rotation between the rotating sleeve 3 and the fixed plate 2, and gives the rotating sleeve 3 and the fixed plate 2 certain axial and radial restrictions.
Further, the end face of the tool apron assembling disc 4 is provided with an installation protrusion 42, the tool apron groove 41 is located on the installation protrusion 42, and the inner wall of the tool apron groove 41 is further provided with a jackscrew hole 43 penetrating through the protrusion. The mounting projection 42 gives the holder pocket 41 a position to be set, and at the same time, it is convenient to open a knock hole 43 for fixing the holder from the side wall of the holder pocket 41.
Preferably, the included angle formed by the axis of the fixed disc 2 and the axis of the vertical arm 1 is 30-60 degrees.
