It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] The utility model embodiment provides a rotatable slot tool bar for a numerically controlled machine tool, such as Figure 1-3As shown, the slot tool rod includes a tool rod 1 and a tool seat 2, the tool seat 2 is located above the tool rod 1, and the lower surface of the tool seat 2 is fixedly connected with a connecting rod 3, the upper surface of the tool rod 1 is provided with a connecting hole 4 matching the connecting rod 3, the lower surface of the tool seat 2 is fixedly connected with a limiting rod 5, and four limiting rods 5 are provided, the upper surface of the tool rod 1 is provided with a limiting hole 6 matching the limiting rod 5, and the upper surface of the tool seat 2 is fixedly connected with a limiting plate 9, the lower surface of the tool seat 2 is provided with a limiting groove 10 matching the limiting plate 9, and the outer wall of the tool seat 2 is threadedly connected with a bolt 11, and the outer wall of the limiting plate 9 is provided with a threaded hole matching the bolt 11.

[0018] It should be noted that, since the existing cutting tool head is fixed on the slot tool rod, it is necessary to adjust the direction of the cutting tool head on the slot tool rod when the slot tool rod is installed on the CNC machine tool. If the direction of the cutting tool head on the slot tool rod is wrong, the slot tool rod needs to be removed from the CNC machine tool and reinstalled, which is very cumbersome. Therefore, in order to solve the problem that the slot tool rod needs to be removed from the CNC machine tool and reinstalled when adjusting the direction of the tool head, which is very cumbersome, the present solution uses a connecting rod 3 to allow the tool holder 2 to be stretched and rotated above the tool rod 1. When the direction of the tool holder 2 needs to be adjusted, the personnel stretches the tool holder 2 upward , so that the limit rod 5 leaves the tool holder 2, the personnel rotates the tool holder 2 to adjust the direction of the tool holder 2. After adjusting the direction of the tool holder 2, the personnel inserts the limit rod 5 into the limit hole 6. The limit rod 5 is located in the limit hole 6 to prevent the tool holder 2 from rotating above the tool rod 1. At this time, the limit plate 9 is located in the limit groove 10. The personnel rotates the bolt 11 to make the bolt 11 enter the bolt hole of the limit plate 9, thereby fixing the limit plate 9 in the limit groove 10 to prevent the tool holder 2 from moving up and down above the tool rod 1. There is no need to disassemble the slot tool rod of the CNC machine tool to adjust the position of the tool head. The operation is simple, saving time and effort.
