[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a multi-angle machine tool fixture.

[0025] A multi-angle machine tool fixture includes a base 1 and multiple mounting holes 2. It also includes an adjustment mechanism disposed on the base 1 for angle adjustment. The adjustment mechanism includes: a rotating member 3 disposed on and rotatably connected to the base 1; a mounting member 4 disposed on and fixedly connected to the rotating member 3; a fixing member 5 disposed on and rotatably connected to the mounting member 4; two mounting slots 19 disposed within the fixing member 5 for component mounting; two spherical hinges 6 disposed within and fixedly connected to the mounting slots 19; two hydraulic cylinders 7 disposed on and fixedly connected to the mounting member 4; multiple buffer springs 8 disposed between the mounting member 4 and the fixing member 5 for buffering operations; and a clamping mechanism disposed within the fixing member 5 for clamping operations.

[0026] refer to Figure 3 and Figure 4 In a preferred embodiment, the adjustment mechanism further includes: a first motor 9, disposed within the base 1 and fixedly connected to the base 1; a first gear 10, disposed at the output end of the first motor 9 and fixedly connected to the output end of the first motor 9; and a second gear 11, disposed on the rotating member 3 and fixedly connected to the rotating member 3.

[0027] refer to Figure 1 and Figure 2 In a preferred embodiment, the clamping mechanism includes: a mounting part disposed within the fixing member 5 for mounting the component; a driving part disposed on the mounting part for providing power; and a clamping part disposed on the driving part for clamping operations.

[0028] refer to Figure 4 and Figure 5 In a preferred embodiment, the mounting part includes: a plurality of fixing grooves 12, wherein the plurality of fixing grooves 12 are disposed within the fixing member 5 for mounting the component; and a fixing seat 13, disposed on the fixing member 5 and fixedly connected to the fixing member 5.

[0029] refer to Figure 5 In a preferred embodiment, the drive unit includes: a second motor 14, which is disposed in the fixed base 13 and fixedly connected to the fixed base 13; a threaded rod 15, which is disposed at the output end of the second motor 14 and fixedly connected to the output end of the second motor 14; and two sliding rods, which are disposed in the fixed groove 12 and fixedly connected to the fixed groove 12.

[0030] refer to Figure 5 In a preferred embodiment, the clamping part includes: two movable members 17, which are disposed on the threaded rod 15 and threadedly connected to the threaded rod 15; and two clamping members 18, which are disposed on the movable members 17 and fixedly connected to the movable members 17.

[0031] In this configuration, the first gear 10 and the second gear 11 are both made of aluminum alloy, which is high in strength and light in weight, making it easier to reduce the weight of the device. At the same time, the first gear 10 and the second gear 11 can mesh with each other. The spherical hinge 6 ensures that the fixed part 5 rotates with the hydraulic cylinder 7, and the hydraulic cylinder 7 can also support the fixed part 5 to ensure the stability of the device. The threaded rod 15 is a bidirectional threaded rod with opposite threads at both ends. When rotating, it can drive the moving parts 17 on both sides to move synchronously in opposite directions.

[0032] This device, through the inclusion of an adjustment mechanism, allows for angle adjustment in two directions. The combined action of these two mechanisms enables precise angle adjustment, enhancing the device's flexibility and ease of use. Furthermore, the device incorporates a clamping mechanism. During clamping operations, the clamping members 18 on both sides move synchronously to hold the workpiece, ensuring consistent clamping force and stable workpiece clamping.

[0033] Working Principle: In use, this device is fixed to the machine tool using fixing bolts through mounting holes 2. The workpiece is then placed on the fixing member 5. Starting the second motor 14 causes the threaded rod 15 to rotate, thus moving the moving members 17 and reducing the distance between them. Simultaneously, the clamping member 18 moves closer to the workpiece and clamps it. After clamping, starting the first motor 9 causes the first gear 10 to rotate, which in turn rotates the second gear 11, which in turn rotates the rotating member 3, thus rotating the workpiece. The device can also adjust the angle of the fixing member 5 by starting the hydraulic cylinders 7 on both sides. When the hydraulic cylinders 7 are working, one side extends while the other shortens to adjust the angle of the fixing member 5, thereby adjusting the workpiece. During adjustment, the buffer spring 8 provides shock absorption and buffering, ensuring stable installation of the workpiece. Through the combined effect of these two angle adjustment methods, the device achieves angle adjustment.

[0034] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
