more than two tool apron chutes 1-2 and tool apron screw holes 1-3 are axially arranged on the top surface of the tool apron 1, more than two slide block chutes 1-4 are radially arranged on the side surface of the tool apron 1, the slide block chutes 1-4 are divided into three sections, namely a large section, a middle section and a small section, from outside to inside according to the hole diameter, and the small sections of the slide block chutes 1-4 are communicated with the corresponding tool apron chutes 1-2;
each cutter block 2 is provided with a cutter block sliding groove 2-2 penetrating through the top and bottom surfaces, and an end gap eliminating screw 4 penetrates through the cutter block sliding groove 2-2 to be in threaded connection with the cutter seat screw hole 1-3 respectively; the bottom surface of each cutter block 2 is fixedly connected with a positioning pin 16, and the lower end of each positioning pin 16 penetrates through the cutter holder sliding groove 1-2 to enter the corresponding sliding block sliding groove 1-4;
a positioning ring 11 is fixedly connected in the large section of the sliding block chute 1-4 through a positioning ring screw 10, an adjusting nut 7 is in clearance fit in the positioning ring 11, the adjusting nut 7 is in a nail shape, an adjusting nut driving hole 7-3 is formed in the outer end of a nail head, a driving key 7-1 is fixedly arranged at the inner end of the nail head and provided with an annular recess, an embedded groove 7-2 is formed in the free end of a nail rod, an elastic element 8 and a gasket 9 are installed in the annular recess, the nail rod penetrates through the elastic element 8, the gasket 9 and the inner hole of the positioning ring 11 and then is sleeved with a friction gasket 13, a check ring 14 is embedded in the embedded groove 7-2, and the elastic force of the elastic element 8 forces a friction surface A11-1; the gasket 9 is provided with a driving groove 9-1, the driving key 7-1 is matched with the driving groove 9-1 to drive the gasket 9 to rotate along with the adjusting nut 7, and the driving key 7-1 can slide along the axial direction of the adjusting nut 7 in the driving groove 9-1;
the adjusting stud 6 comprises an external thread A6-1 and an external thread B6-2, a stud driving hole 6-3 is formed in the outer end of the adjusting stud, the pitch of the external thread A6-1 is larger than that of the external thread B6-2, the screwing directions are opposite, the external thread A6-1 is in threaded fit with an internal thread of a center hole of the adjusting nut 7, and the external thread B6-2 is in threaded fit with an internal thread of the sliding block 12;
the slide block 12 is positioned in a small section of the slide block sliding groove 1-4 and is fixedly connected with the lower end of the positioning pin 16.
During fine adjustment, the adjusting stud 6 is driven to rotate by a tool at the stud driving hole 6-3, at the moment, the friction surface A11-1 and the friction surface B13-1 are attached to each other under the pre-elasticity action of the elastic element 8, and the adjusting nut 7 is used for fixing relative to the tool apron 1. And each time the adjusting stud 6 rotates for one circle, the adjusting stud 6 moves one pitch of the external thread A relative to the adjusting nut 7, namely the tool apron, and the slide block 12 drives the positioning pin 16 and the tool block 2 to move one pitch of the external thread B in the opposite direction. The actual distance of movement of the insert 2 relative to the holder 1 is now one pitch of the external thread a minus one pitch of the external thread B. The micron-scale adjustment of the diameter adjustment of the boring cutter is realized by reasonably setting the numerical values of the thread pitch A and the thread pitch B. Due to the pre-elastic force of the elastic element 8, the axial thread fit clearance of the external thread A6-1 and the external thread B6-2 during the fit process is eliminated. Continuity of size adjustment is achieved.
During rough adjustment, the adjusting nut 7 is pressed by a tool to separate the friction surface A11-1 from the friction surface B13-1. At the moment, the adjusting nut 7 and the tool apron 1 are released from the relative fixed state, and the rotation around the assembling axis of the adjusting stud 6 can be realized. When the tool is used for driving the adjusting nut 7 and the adjusting stud 6 to rotate while pressing inwards, only the thread pair of the external thread B6-2 and the sliding block 12 plays a transmission role. The slide block 12 drives the positioning pin 16 and the knife block 2 to move relative to the knife holder 1 by a pitch of the external thread B6-2 every time the slide block rotates one circle.
The tool holder 1 and the tool block 2 are pressed tightly using bolts. When the common bolt is used for pressing, after the bolt is loosened, in the adjusting process, a gap is generated between the cutter holder positioning key 1-1 and the cutter block positioning key 2-1 after the cutter holder 1 and the cutter block 2 move at the relative positions. This gap has various configurations. After the bolt is compressed again, after the gap between the bolt and the cutter disappears, the actual size of the cutter is larger or smaller than the size which is not compressed after adjustment.
The invention arranges more than one group of holes on the flange surface of the end clearance eliminating screw 4, namely the screw pressing surface 4-3, a spring 4-1 is arranged in the hole, and a ball 4-2 is arranged below the spring and points to the direction of the thread. In a free state, the ball 4-2 extends out of the flange surface, and the spring 4-1 has pre-elasticity.
When the fixed cutter block 2 needs to be pressed and fixed, the end gap eliminating screw 4 is rotated, so that the cutter block pressing surface 2-3 presses the ball 4-2, the spring 4-1 contracts under the pressure of the ball, and the ball 4-2 retracts into the hole. The screw pressing surface 4-3 is tightly attached to the knife block pressing surface 2-3.
When the position of the cutter block 2 needs to be adjusted, the end clearance eliminating screw 4 is properly loosened. The knife block pressing surface 2-3 is separated from the screw pressing surface 4-3, the ball 4-2 is always in contact with the knife block pressing surface 2-3 under the action of elastic force and has certain pre-pressure, and the pressure is provided by the spring 4-1.
During the adjustment process of the cutter block 2, pre-pressure exists all the time, and the contact gap between the cutter block positioning key 2-1 and the cutter seat positioning key 1-1 is eliminated. After the adjustment is finished and the pressing is carried out again, the position of the cutter block is unchanged.
The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; those skilled in the art can make many possible variations or modifications to the invention using the methods and techniques disclosed above, or to modify equivalent embodiments without departing from the scope of the invention.
