[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1-4 In this embodiment, a forming finishing turning tool for rotor wheel groove processing includes a tool row 1 for connection and a turning tool located on the tool row 1. The turning tool includes a tool handle 5 and a tool head 6 for installation support. At least three groups of turning tools are arranged on the tool row 1 to facilitate replacement of the tool head 6 in case of damage.

[0024] In this embodiment, a through groove 2 is also formed on the front of the tool row 1 for the turning tool to adjust its position. A connecting structure for connecting the tool row 1 is also provided on the turning tool. The connecting structure includes an I-shaped plate 3 slidably connected to the tool row 1, and a tool handle 5 is fixedly connected to the I-shaped plate 3.

[0025] Preferably, the I-shaped plates 3 include two pieces, and the two I-shaped plates 3 are symmetrically distributed on the front and rear sides of the knife row 1, and a slider 4 is provided between the two I-shaped plates 3. The slider 4 is slidably connected to the through groove 2, and the slider 4 is restricted to slide in the through groove 2, so that the I-shaped plates 3 can be stably slid and adjusted relative to the knife row 1.

[0026] It is worth noting that the slider 4 is inserted into the two I-shaped plates 3 and penetrates the I-shaped plate 3 at the rear side, so that the slider 4 can be pulled out between the two I-shaped plates 3 to facilitate the I-shaped plates 3 to be separated from the knife row 1.

[0027] It should be noted that the knife handle 5 is in a cubic shape, and through holes 7 are provided between three opposite sides of the knife handle 5 , and the knife head 6 is inserted into the through holes 7 to be installed on the knife handle 5 .

[0028] A thread is provided in the through hole 7 and a plunger 8 is threadedly connected thereto. The plunger 8 is threadedly extended to the inside of the through hole 7 to abut against the cutter head 6 , so that the cutter head 6 inserted into the handle 5 through the through hole 7 can be fixedly connected to the handle 5 .

[0029] Preferably, a hexagonal countersunk hole 9 is provided on one end of the plunger 8, and the hexagonal countersunk hole 9 can facilitate the rotation of the plunger 8 by pulling it with a hexagonal wrench.

[0030] In this embodiment, a T-shaped slot 10 is further provided on the opposite side surface of the I-shaped plate 3, and a connecting plate 11 is slidably installed between the two I-shaped plates 3. Both ends of the connecting plate 11 are T-shaped corresponding to the T-shaped slot 10, so that the connecting plate 11 can slide between the two I-shaped plates 3 to adjust its position.

[0031] In this embodiment, a positioning pin 13 is also threadedly installed on the connecting plate 11, and a positioning hole 12 for threaded connection of the positioning pin 13 is opened on the outer wall of the tool row 1. By rotating the positioning pin 13 until the positioning pin 13 is threadedly connected to the positioning hole 12, the position of the I-plate 3 relative to the tool row 1 can be limited.

[0032] It should be noted that there are a number of positioning holes 12 evenly distributed outside the tool row 1 , and a number of positioning holes 12 arranged at equal intervals provide a plurality of fixed positions, so that the position of the turning tool relative to the tool row 1 can be adjusted conveniently and flexibly.

[0033] The working principle of the above embodiment is:

[0034] The cutter head 6 is inserted into one of the through holes 7 of the tool handle 5, and the cutter head 6 and the tool handle 5 are fixedly assembled by threading the pre-tightening plunger 8 in the remaining through holes 7, and the I-plate 3 connected to the tool handle 5 is slid relative to the tool row 1, and the connecting plate 11 between the I-plates 3 and the tool row 1 are fixed to each other, that is, the connecting plate 11 and the tool row 1 are fixed by rotating the locating pin 13 to fix the position of the cutter head 6. At this time, the tool row 1 is loaded on the precision lathe. When one of the cutter heads 6 is damaged, it is only necessary to adjust the position of the I-plate 3 relative to the tool row 1, and by pulling the slider 4 to the rear side of the I-plate 3 on the rear side, so that the space between the two I-plates 3 is hollow, so that the I-plate 3 can be slid out along the tool row 1, and the processed cutter head 6 can be replaced without removing the tool row 1.
