Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2, the utility model relates to a lengthened boring cutter bar for an accessory head, which comprises a connecting rod 1, a cutter mounting groove, a cutter 2, a first supporting seat 3, a second supporting seat 4 and a balancing weight component 5, wherein the connecting rod 1 is divided into a left end, a middle part and a right end, the cutter mounting groove is arranged at the left end, the cutter 2 is arranged on the cutter mounting groove, the first supporting seat 3 and the second supporting seat 4 are arranged at the middle part, and the balancing weight component 5 is arranged at the right end.
The balancing weight component 5 comprises a screw rod 51, a balancing weight 52, a locking nut 53 and an end face flange 54, wherein the balancing weight 52 is arranged outside the screw rod 51, the locking nut 53 is arranged on the balancing weight 52, and the end face flange 54 is arranged behind the balancing weight 52.
The first supporting seat 3 is internally provided with a first transmission key 6. A second transmission key 7 is arranged in the second supporting seat 4.
The first supporting seat 3 and the second supporting seat 4 both comprise mounting holes, and key grooves matched with the key grooves of the connecting rods are formed in the upper parts of the mounting holes; the connecting rod 1 is sequentially arranged in the mounting holes of the first supporting seat 3 and the second supporting seat 4; the first transmission key 6 and the second transmission key 7 are respectively fixed in the key grooves of the first supporting seat 3 and the second supporting seat 4 by screws; the balancing weight subassembly 5 is installed at the right-hand member of connecting rod 1. Wherein, balancing weight 52 is installed at the right end of connecting rod 1 through screw 51 and terminal flange 54, and lock nut 53 locks balancing weight 52 on connecting rod 1.
