DETAILED DESCRIPTION

[0021] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than 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 the present application.

[0022] The present application embodiment discloses a device for extending a tool rest of a CNC vertical lathe. Figure 1 and Figure 2 The device of the CNC vertical lathe tool rest extension frame includes a support portion 10, at least one group of extension tables 20, tool rests 30 equal to the number of extension tables 20, and a drive motor 40. During installation, several groups of extension tables 20 are placed on the side of the support portion 10, and are fixed by the extension tables 20, so that the support portion 10 and the extension tables 20 are detachably connected and fixed. A drive motor 40 is installed above each group of extension tables 20, and the output end of each group of drive motors 40 is connected to a group of tool rests 30, so that each group of tool rests 30 is rotatably arranged below a group of extension tables 20, and the position of the tool is adjusted by the rotation of the tool rest 30.

[0023] See also Figure 3 and Figure 4The support part 10 includes a positioning bracket 11, a limiting base column 12, a limiting extension column 13 and a limiting screw ring 14. When placed, a plurality of expansion platforms 20 can be arranged in a lateral array on the side of the positioning bracket 11. One end of the limiting base column 12 is rotatably connected to the positioning bracket 11, and the other end of the limiting base column 12 is detachably connected and fixed to the adjacent end of the limiting extension column 13. The end of the limiting extension column 13 away from the limiting base column 12 is threadedly connected to the limiting screw ring 14, so that after tightening the limiting screw ring 14, the positioning bracket 11 and the limiting screw ring 14 can be used to clamp and tighten the plurality of expansion platforms 20 to complete the installation operation.

[0024] In this embodiment, an insert block 111 is formed on one side of the positioning bracket 11 facing the expansion platform 20, and an avoidance groove 112 is formed on the top of the positioning bracket 11 and penetrates the positioning bracket 11 upward. A slot 21 penetrating the expansion platform 20 is formed in the middle of the expansion platform 20, and the slot 21 is used to cooperate with the insert block 111, so that when the expansion platform 20 is placed close to the positioning bracket 11, the insert block 111 can be inserted into the slot 21 and support the group of expansion platforms 20. The limiting base column 12 can be deflected and moved through the avoidance groove 112 during the installation process to avoid interference between the limiting base column 12 and the positioning bracket 11.

[0025] In this embodiment, the limiting base column 12 includes at least one basic rod 121 and a positioning shaft 122. The end of the basic rod 121 close to the positioning bracket 11 is penetrated by the positioning shaft 122 and fixedly connected thereto, and both ends of the positioning shaft 122 are rotatably connected to the inner wall of the positioning bracket 11, so that the basic rod 121 can deflect with the positioning shaft 122 as the rotation axis and can pass through the avoidance groove 112. An external thread is formed on the outer wall of the end of the basic rod 121 away from the positioning shaft 122, and a threaded hole is formed at the center, so that it can be connected to the limiting extension column 13 and the limiting screw ring 14.

[0026] In this embodiment, the limit extension column 13 includes a plurality of extension rods 131, and a connecting stud 132 connected to the threaded hole of the basic rod 121 is formed at one end of the extension rod 131 facing the basic rod 121, so that the extension rod 131 can be screwed and fixed with the basic rod 121. An external thread is formed on the outer wall of the end of the extension rod 131 away from the basic rod 121, and a threaded hole is formed at the center. The threaded hole of the extension rod 131 can also be screwed and connected with the connecting stud 132, so that multiple extension rods 131 can be assembled and connected along the axial direction to adapt to the fixation of different numbers of expansion platforms 20. The limit screw ring 14 can be sleeved on the outside of the basic rod 121 or the extension rod 131 and screwed with it using threads.

[0027] See also Figure 5A semicircular limiting groove 22 is formed on the top of the expansion platform 20, and the base rod 121 or the extension rod 131 can fit the inner wall of the limiting groove 22, and after tightening the limiting screw ring 14, the limiting screw ring 14 can be pressed against the adjacent expansion platform 20. The height of the limiting screw ring 14 is greater than the diameter of the limiting groove 22, so as to prevent the limiting screw ring 14 from moving into the limiting groove 22 after tightening and affecting the fixation of the expansion platform 20.

[0028] See also Figure 6 The tool holder 30 includes an adjustment dial 31 connected to the output end of the driving motor 40 at the center, and the driving motor 40 can be used to drive the adjustment dial 31 to deflect. An even number of chucks 32 are arranged below the adjustment dial 31, and the even number of chucks 32 are distributed in pairs along the radial direction of the adjustment dial 31 at equal intervals. One end of each chuck 32 close to the adjustment dial 31 is rotatably connected to the adjustment dial 31 by a positioning column 33, and the two paired chucks 32 are connected by a spring 34, so that the two paired chucks 32 can be pulled by the spring 34 to deflect and clamp the tool placed between them.

[0029] 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.
