[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The embodiment of the present application discloses a combined tool holder for a lathe.

[0027] In this embodiment, a tool holder for a lathe is provided with a tool holder fixing hole 11 at the bottom of the tool holder body 1 for fixing the tool holder body 1 on the lathe. The tool holder for a lathe comprises a tool holder body 1, the tool holder body 1 is provided with a U drill mounting hole 13, and the tool holder body 1 is provided with two tool rod mounting holes 12, a U drill mounting hole 13 is provided in the middle of the tool holder body 1, and tool rod mounting holes 12 are provided in the tool holder body 1 on both sides of the U drill mounting hole 13. The U drill mounting hole 13 can be used to movably mount the U drill body 10; the tool rod mounting hole 12 can be used to movably mount the tool rod body 9. The tool rod mounting hole 12 and the U drill mounting hole 13 pass through the thickness direction of the tool holder body 1.

[0028] A shank fixing hole 6 and a U drill fixing hole 5 are provided in the tool holder body 1 in a direction perpendicular to the thickness. The shank fixing hole 6 is connected to the shank mounting hole 12, and the U drill fixing hole 5 is fixed to the U drill mounting hole 13. The shank body 9 is installed and inserted into the shank mounting hole 12, and is fixed via the shank fixing hole 6 by a locking bolt. The U drill body 10 is installed and inserted into the U drill mounting hole 13, and is fixed via the locking bolt via the U drill fixing hole 5. The U drill mounting hole 13 is a circular hole, and the shank mounting hole 12 is a square hole.

[0029] A baffle fixing hole 14 is provided on the tool holder body 1 around the side of the tool rod mounting hole 12 away from the tool rod body 9, and the tool rod baffle 2 is fixed to the tool holder body 1 through the baffle fixing hole 14 by means of the baffle fixing bolt 4; a baffle fixing hole 14 is provided on the tool holder body 1 around the side of the U drill mounting hole 13 away from the U drill body 10, and the U drill baffle 3 is fixed to the tool holder body 1 through the baffle fixing hole 14 by means of the baffle fixing bolt 4.

[0030] In this embodiment, as a further optimization, a tool bar coolant through hole 7 is provided through the center of the tool bar baffle 2; and a U drill coolant through hole 8 is provided through the center of the U drill baffle 3.

[0031] In this embodiment, the lathe combined tool holder includes a tool holder body 1. The design of the tool holder body 1 not only realizes the coexistence installation of the U drill and the tool bar, but also improves the processing flexibility and efficiency through reasonable layout. Specifically, the tool holder body 1 is provided with at least one U drill mounting hole 13 and at least one tool bar mounting hole 12. Such a design enables the lathe to be equipped with tools with different functions at the same time to meet various processing requirements such as turning, drilling, and boring. The layout of the tool bar mounting hole 12 and the U drill mounting hole 13 takes into account the fluid mechanics characteristics during the processing process, which facilitates the effective delivery of the coolant to the tool working surface, reduces the temperature rise of the blade, and improves the processing accuracy and tool durability. The structural design of the tool holder body 1 also reserves a tool fixing and coolant channel. Through the setting of the locking mechanism and the coolant through hole, the stability and cooling efficiency of the tool under high load are guaranteed at the same time. The cooling and lubrication problem of the blade during the processing process is fully considered. On the premise of increasing the cutting amount of the blade to a certain extent, the service life of the blade is greatly improved. The increase in the cutting amount of the blade of the combined tool holder indirectly increases the processing efficiency of the machine tool. This combined tool holder structure is suitable for a variety of processing scenarios, especially mass production environments with strict requirements on processing efficiency, and shows good adaptability and versatility.

[0032] In the embodiment of the present application, the modular tool holder can be adapted to various lathes of different models and specifications by adopting a standardized interface design, thereby improving its versatility and flexibility. The integrated fixing holes and bolt holes can also facilitate quick installation and adjustment of the tool position, simplify the tool change process, reduce downtime, and improve machine tool utilization.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
