The first end 11 of the tool head seat 10 is fixedly connected to the slide column 100, that is, when the tool head seat 10 is connected to the vertical lathe, the slide column 100 is used to drive the tool head seat 10 to move in the vertical and horizontal directions; in addition, one side of the second end 12 of the tool head seat 10 is used to be fixedly connected to the tool holder 20.

[0026] The tool holder 20 includes a first surface 21 and a second surface 22 that are arranged opposite to each other, and a broaching seat 23 that matches the tool head seat 10 is arranged on one side of the first surface 21. The broaching seat 23 includes a guide portion.

[0027] Specifically, the tool holder 20 is mounted on the tool head holder 10 via the broaching seat 23 ; in addition, in actual application, a corresponding tool (not shown) is mounted on one side of the second surface 22 of the tool holder 20 for specific processing tasks.

[0028] In one implementation scenario, a receiving cavity (not shown) is provided in the tool head seat, and the receiving cavity matches the above-mentioned broaching seat 23 , that is, the receiving cavity is used to accommodate at least part of the broaching seat 23 so that the turning tool holder 20 can be installed on the tool head seat 10 .

[0029] The positioning assembly 30 includes a first positioning member 31 and a second positioning member 32 that match each other. The first positioning member 31 is disposed on one side of the second end 12 of the tool head seat 10 , and the second positioning member 32 is disposed on the second surface 22 of the tool holder 20 .

[0030] Specifically, during the installation of the tool holder 20 , the first positioning member 31 and the second positioning member 32 cooperate with each other to guide and limit the position of the tool holder 20 relative to the tool head seat 10 .

[0031] The tool gripping mechanism for a vertical lathe proposed in the present application provides a corresponding guide portion on the broaching seat 23 of the tool holder 20, so that when the tool holder 20 is replaced, the guide portion plays a certain guiding role, thereby improving the replacement efficiency of the tool holder 20. In addition, the tool gripping mechanism also includes a positioning assembly 30, which includes a first positioning member 31 and a second positioning member 32 that match each other. By providing the first positioning member 31 and the second positioning member 32, during the installation process, the tool holder 20 is limited to a certain extent, and the stability of the tool holder 20 on the vertical lathe is improved.

[0032] In one embodiment, please continue to refer to Figure 1 The broach seat 23 includes a broach 231 and a connecting member 232. The connecting member 232 is fixedly connected to the broach 231 at a side away from the first surface 21.

After the tool holder 20 is installed on the tool head seat 10, the broaching nail 231 on the tool holder 20 matches the broaching claw 40 through the receiving cavity of the tool head seat 10; that is, during the processing, the broaching claw 40 clamps the broaching nail 231, so that the vertical lathe works and drives the tool on the tool holder 20 to process the workpiece.

[0034] In one embodiment, the connecting member 232 includes a guide portion, wherein the guide portion is in a truncated cone shape, and the diameter of the cross section of the guide portion decreases in a direction away from the first surface 21 .

[0035] Specifically, except for the connection with the first surface 21, the connecting member 232 serves as a guide and is truncated; that is, in the horizontal direction, the cross section of the guide at any height is circular, and as the horizontal height increases, the diameter of the cross section of the guide decreases successively. By setting the guide to be truncated, the end of the guide with a smaller diameter preferentially enters the receiving cavity of the tool head seat 10 during the installation of the tool holder 20, that is, the matching difficulty between the connecting member 232 of the broach seat 23 and the receiving cavity of the tool head seat 10 is reduced, and the installation efficiency of the broach seat 23 is improved.

[0036] In another embodiment, please combine Figure 1 See also Figure 2 , Figure 2 2 is a schematic cross-sectional view of an embodiment of a connector. The connector 232 is cylindrical. A chamfer is provided on one side of the connector 232 near the rivet 231, and the chamfer serves as a guide.

[0037] Specifically, by providing a chamfer on the side of the connecting member 232 away from the first surface 21, the connecting member 232 can enter the accommodating cavity of the tool head seat 10, thereby improving the installation efficiency of the broach seat 23.

[0042] The above scheme improves the efficiency of the installation process and the stability of the tool holder 20 in the horizontal direction after installation by providing a plurality of protrusions 310 and a plurality of recesses 320 arranged in an alternating manner, so as to cooperate with each other between the plurality of groups of protrusions 310 and recesses 320 matched in the vertical direction.

[0043] In another embodiment, please continue to refer to Figures 1 to 4 For the positioning assembly 30 in any of the above embodiments, the protrusion 310 includes a magnetic attraction portion, which is used to be adsorbed with the corresponding recessed portion to assist in positioning between the first positioning member 31 and the second positioning member 32.

[0044] Specifically, the protrusion 310 has a first magnetism, and the recessed portion 320 matching the protrusion 310 has a second magnetism, and the first magnetism is opposite to the second magnetism, that is, when the protrusion 310 is close to the recessed portion 320, the protrusion 310 and the corresponding recessed portion 320 are attracted and limited to each other through the first magnetism and the second magnetism, so as to improve the installation efficiency of the tool holder 20.

[0045] In another embodiment, the first positioning member 31 is annularly disposed on one side of the second end 12 of the tool head seat 10, and a first magnetic member is disposed between the first positioning member 31 and the tool head seat 10.
