[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0017] Such as Figures 1 to 3As shown in the figure, a multi-angle adjustment support frame for the tool head of a numerically controlled machine tool includes a base 1 for connecting to the machine tool. A fixing plate 4 is rotatably arranged on the base 1. A limiting seat 7 is arranged above the base 1. The limiting seat 7 is connected to the base 1 through a plurality of brackets 6. A sphere 8 is rotatably arranged in the limiting seat 7. The sphere 8 is used to drive the tool 9 to adjust the angle. One end of the sphere 8 close to the fixing plate 4 is provided with a second limiting rod 10, and the other end is fixed with a tool 9. The fixing plate 4 is provided with a limiting mechanism for locking the second limiting rod 10 when the sphere 8 rotates to the required position. The fixing plate 4 is rotatably arranged on the base 1 through a rotating shaft 19. A first limiting rod 3 for limiting the rotating shaft 19 is arranged at the lower end of the fixing plate 4.

[0018] The working process of this embodiment is as follows: First, open the limiting mechanism so that the sphere 8 can rotate freely. Then, according to the working requirements, rotate the sphere 8 to move the tool 9 to the corresponding position. Then, according to the position of the second limiting rod 10, rotate the rotating shaft 19 so that the fixing plate 4 rotates to the position corresponding to the second limiting rod 10. Then, move the limiting mechanism to a suitable position to limit the second limiting rod 10, and then limit the rotating shaft 19 so that it cannot rotate, so as to achieve the purpose of fixing the position of the sphere 8.

[0019] Preferably, the limiting mechanism includes a through groove 5 on the fixing plate 4. As Figure 1 shown, the through groove 5 penetrates through the front and rear surfaces of the fixing plate 4. A U-shaped plate 12 is slidably arranged in the through groove 5. First sliding grooves 14 are arranged on both side walls of the U-shaped plate 12. A group of fixing rods 13 are slidably arranged in the first sliding grooves 14. The fixing rods 13 are fixed to the U-shaped plate 12 through fixing nuts. A first telescopic rod 20 is arranged at the center of the fixing plate 4. A connecting block 11 is arranged at the end of the first telescopic rod 20. The end of the first telescopic rod 20 extends into the second limiting rod 10 to lock the first telescopic rod 20 and the second limiting rod 10. The first telescopic rod 20 and the connecting block 11 are used for limiting the rotation of the sphere 8 in the horizontal direction to ensure that the sphere does not move axially. A second sliding groove 21 is arranged on the fixing plate 4. The second sliding groove 21 penetrates through the upper end surface of the fixing plate 4 and communicates with the through groove 5. A moving plate 16 is arranged on the second sliding groove 21. A stud 15 is rotatably arranged on the moving plate 16. A threaded hole 22 matching the stud 15 is arranged on the U-shaped plate 12.

[0020] Working process: When the sphere 8 rotates horizontally only, the sphere 8 is limited by the first telescopic rod 20 and the connecting block 11. When the sphere 8 rotates not only horizontally, the first telescopic rod 20 needs to be retracted first to avoid collision with the second limiting rod 10. And when the fixing plate 4 corresponds to the position of the second limiting rod 10, according to the position of the second limiting rod 10, the U-shaped plate 12 is slid to a suitable position, then the two fixing rods 13 are moved backward. At the same time, the U-shaped plate 12 is moved so that the second limiting rod 10 is between the two fixing rods 13, and the fixing rod 13 is moved to clamp the second limiting rod 10, and then fixed by a fixing nut, so that the two fixing rods 13 lock the second limiting rod 10. Then the moving plate 16 is slid, and through the stud 15 and the screw hole 22, the U-shaped plate 12 and the fixing plate 4 are locked, and the limiting is completed.

[0021] An annular groove 2 is provided on the base 1. A first limiting rod 3 is slidably arranged in the annular groove 2. A limiting nut is rotatably arranged on the first limiting rod 3. A second telescopic rod 18 is hinged on the rotating shaft 19. A clamp 17 for connecting with the bracket 6 is arranged at the telescopic end of the second telescopic rod 18. Cooperating with the limiting nut on the first limiting rod 3, the rotating shaft 19 is double-limited, the structure is stable, the stability of the sphere 8 when it is stationary is ensured, and it is convenient for the cutting work to be carried out; a steering sleeve 23 for placing the sphere 8 is arranged on the limiting seat 7, which can better limit the sphere 8 and is not easy to fall off when it receives a large impact force. At the same time, it is convenient for the sphere 8 to turn and is convenient to use.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
