Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 3, a machine tool fixing mechanism includes a cutter head 1, a cutter bar 2 installed in a cutter groove 4 of the cutter head 1, and a cutter 7 installed on the cutter bar 2. The edge of the cutter head 1 is provided with a plurality of cutter grooves 4 which are uniformly distributed on the circumference, and each cutter groove 4 is provided with three inner wall surfaces, namely a first inner wall surface which is arranged outwards and a second inner wall surface and a third inner wall surface which are oppositely arranged left and right. The first side surface of the cutter bar 2 is attached to the first inner wall surface of the cutter groove 4, the third side surface of the cutter bar 2 is attached to the third inner wall surface of the cutter groove 4, a gap 6 is arranged between the second side surface of the cutter bar 2 and the second inner wall surface of the cutter groove 4, and the smaller the space of the cutter groove 4 is, the smaller the gap 6 is. A first mounting hole is formed in the outward fourth side surface of the cutter bar 2, the first mounting hole is a through hole and penetrates through the first side surface and the fourth side surface of the cutter bar 2, and the first mounting hole can be a light hole or a threaded hole; be equipped with first screw on the first inner wall face, locking bolt 3 passes behind the first mounting hole and locks in first screw, and cutter arbor 2 passes through locking bolt 3 and locks on the first internal face in sword groove 4, and the head of locking bolt 3 is established on the fourth side of cutter arbor 2, convenient operation.
