The working principle is as follows: the cutter head of the existing milling cutter inevitably generates abrasion in the process of long-time use, most of the abrasion generated by the cutter seat of the milling cutter in the process of long-time use is small, but the cutter head of the milling cutter needs to replace the whole milling cutter after abrasion, the cost is high, when the cutter seat 1, the fixed seat 2 and the connecting seat 3 need to be connected, firstly, the stop block 51 is pushed, the bottom end of the stop block 51 moves in the moving groove 52, the inner wall of the clamping groove 55 extrudes the fixture block 54, the fixture block 54 generates elastic deformation, the limiting effect of the fixture block 51 on the stop block 51 is relieved by the fixture block 54 at the moment, when the stop block 51 is pushed to the limit rapidly to the left side, the bottom end of the stop block 51 extrudes the fixture block 54 which is glued in the moving groove 52 and is close to the left side, the fixture block 54 generates elastic deformation, when the stop block 51 moves to the limit, the extrusion force of the fixture block 54 disappears after the stop block 51 moves to the limit, at the moment, the fixture block 54 returns to the original position and is clamped with the clamping groove 55 under the action of the self reducing force, the effect of pushing the stop 51 to move the connecting rod 48 and the limit the stop plate 49, and the stop the connecting rod 51 can be pushed again when the connecting rod 49 and the limit is relieved.
Then align locating piece 57 with constant head tank 58 and then insert the inside of fixing base 2 with the one end of connecting seat 3, make locating piece 57 insert the inside of constant head tank 58, play the effect of fixing a position and leading the inserting of connecting seat 3 through the effect of locating piece 57 and constant head tank 58 combination.
When the positioning block 57 is inserted into the positioning groove 58, the connecting block 41 is synchronously inserted into the connecting groove 42, when the connecting block 41 is inserted into the connecting groove 42, the limiting cavity 43 arranged on the side of the connecting block 41 far away from the connecting seat 3 extrudes the inclined surface arranged on the limiting block 44, so that the limiting block 44 drives the movable block 45 to move under the action of the extrusion force, so that the movable block 45 moves in the movable groove 46 and extrudes the return spring 47, so that the return spring 47 elastically deforms, the movable block 45 drives the fixedly connected connecting rod 48 and the pressing plate 49 fixedly connected with the connecting rod 48 to synchronously move when moving, when the connecting block 41 is completely inserted into the connecting groove 42, the limiting block 44 is completely inserted into the inner wall of the limiting cavity 43, at the moment, the extrusion force of the limiting cavity 43 on the limiting block 44 disappears, the movable block 45 drives the limiting block 44 to return to the original position and be clamped with the limiting cavity 43 under the action of the return spring 47, so as to limit the connecting block 41, and connect the fixed seat 2 and the connecting seat 3.
When the connection between the tool apron 1, the fixing seat 2 and the connecting seat 3 is to be released, the pressing plate 49 is pressed towards the fixing seat 2, the pressing plate 49 is made to move towards the fixing seat 2, the connecting rod 48 drives the movable block 45 and the limiting block 44 to move synchronously, the limiting block 44 is made to release the effect of clamping with the limiting cavity 43, then the connecting seat 3 or the fixing seat 2 is pulled towards the direction away from each other to make the connecting block 41 be released from the inside of the connecting groove 42, the positioning block 57 is released from the inside of the positioning groove 58, and the connection between the tool apron 1, the fixing seat 2 and the connecting seat 3 can be released.
Present milling cutter is connected between with the milling machine with dismantle and change comparatively inconvenient, when will installing tool bit 6, at first align inserted block 77 and slot 78, then insert inserted block 77 to the inside of slot 78, the effect of leading is played to tool bit 6 through the effect of inserted block 77 and slot 78, inserted block 77 produces the extrusion to the joint piece 79 of gluing on the slot 78 inner wall when inserting to the inside of slot 78 simultaneously, make the joint piece 79 that adopts rubber material produce elastic deformation, the extrusion force of inserted block 77 to joint piece 79 disappears after inserted block 77 inserts completely to the inside of slot 78, joint piece 79 resumes to the normal position and with joint groove 81 block under the effect of the reducing force of self, play and carry out the effect of auxiliary fixation to tool bit 6.
When the inserting block 77 is inserted into the slot 78 to the maximum, the fixing block 83 is inserted into the second fixing groove 82, and the inserting groove 85 is also inserted into the inserting block 84, when the inserting groove 85 is inserted into the inserting block 84, one side of the inner wall of the inserting block 84 extrudes the first engaging block 86, so that the first engaging block 86 made of rubber generates elastic deformation, and at the same time, one side of the inserting groove 85, which is far away from the first engaging block 86, extrudes the second engaging block 88 glued on the inner wall of the inserting block 84, so that the second engaging block 88 generates elastic deformation, when the inserting groove 85 is completely inserted into the inserting block 84, the extrusion force of the inner wall of the inserting block 84 on the first engaging block 86 disappears, the extrusion force of the inserting groove 85 on the second engaging block 88 also disappears synchronously, and at this time, the first engaging block 86 and the second engaging block 88 both recover to the original shape under the action of their own reducing force and engage with the first engaging groove 87 and the second engaging groove 89, respectively, thereby achieving the effect of assisting in fixing the connection between the tool bit 6 and the tool holder 1.
After the insert block 77 is completely inserted into the slot 78, the first fixing groove 71 formed in the tool bit 6 is communicated with the through groove 73, at the moment, the bolt 75 is inserted into the first fixing groove 71 and the through groove 73, the bolt 75 is screwed, then the nut 76 is sleeved on one end, far away from the tool bit 6, of the bolt 75, so that the tool bit 6 is connected with the tool holder 1, the first cushion block 72 inside the first fixing groove 71 and the second cushion block 74 glued inside the through groove 73 play a role in increasing friction between the inner walls of the bolt 75 and the first fixing groove 71 and friction between the nut 76 and the inner wall of the through groove 73, and connection between the tool bit 6 and the tool holder 1 is fastened.
The effect of guide block 90 through adopting the arc design plays and pops out the sweeps that produces when milling processing and avoids producing the effect that influences to tool bit 6, produces the collision between the sweeps that produces when tool bit 6 mills and guide block 90, and the sweeps that will splash outwards leads to popping out through the arc design of guide block 90.
