Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, the present invention provides a four-axis machining fixture, including a rotating shaft 1, a mounting base 2 and several chucks 3. The rotating shaft 1 is provided with a mounting groove 11, the mounting base 2 is disposed in the mounting groove 11, and several chucks 3 are spaced apart on the mounting base 2. The chucks 3 have screw holes 30. The chucks 3 are used to clamp the product 4 and then clamp the product 4 by screwing screws into the screw holes 30.

[0021] Specifically, the rotating shaft 1 is mounted on the drive module of the CNC equipment and rotates and / or moves as driven by the drive module. When product 4 needs to be installed, simply assemble product 4 onto the chuck 3, and then tighten the chuck 3 by inserting screws into the screw holes 30 to fix product 4 in place. When product 4 needs to be removed, simply loosen the screws; it is simple and convenient.

[0022] In this embodiment, the chuck 3 includes a mounting part 31 and two clamping parts 32. The two clamping parts 32 are both disposed on the top of the mounting part 31, and there is a gap 33 between the two clamping parts 32. The two clamping parts 32 are both provided with screw holes 30, and the screw holes 30 of the two clamping parts 32 are connected to each other.

[0023] Both clamping parts 32 are provided with screw holes 30, which can be turned to control the two clamping parts 32 to move closer or further apart. The gap 33 between the clamping parts 32 is used to compensate for the specification error of the product 4, ensuring that the product 4 within the error range can be placed between the two clamping parts 32 and clamped.

[0024] Specifically, the mounting part 31 is detachably mounted on the mounting base 2, so that a suitable clamp 3 can be replaced and mounted on the mounting base 2 according to the specifications and shape of the product 4, thereby improving the versatility of this utility model.

[0025] Specifically, each of the two clamping parts 32 has a limiting part 34 at one end close to the other, and the limiting part 34 has an inclined surface 35. That is, when the product 4 slides into the space between the two clamping parts 32 from the same side, after the two clamping parts 32 clamp the product 4, the inclined surface 35 of the limiting part 34 will abut against the product 4, so that the product 4 cannot be detached from the top of the clamping part 32, thereby ensuring the stability of the clamping.

[0026] In this embodiment, the mounting base 2 is detachably installed in the mounting groove 11, and the mounting base 2 abuts against the top and one side of the mounting groove 11. Specifically, the mounting groove 11 has two outer walls, a bottom and a side, for accommodating and positioning the mounting base 2, thereby ensuring the stability and accuracy of the mounting base 2 installation.

[0027] Specifically, the mounting groove 11 is provided with a positioning pin 12, and the mounting base 2 is provided with a positioning hole 21. The positioning pin 12 is inserted into the positioning hole 21. The mounting groove 11 is provided with a first screw hole 13, and the mounting base 2 is provided with a second screw hole 22. The top of the second screw hole 22 is provided with a recessed hole 23. The first screw hole 13 and the second screw hole 22 are connected and fixed by screws. The recessed hole 23 is used to accommodate the screw head.

[0028] The mounting base 2 and the mounting slot 11 are also detachable, so the mounting base 2 can be replaced for products 4 with different specifications and quantities, which further improves the versatility of this utility model. It also means that other parts of this utility model, except for the mounting base 2 and the clamp 3, do not need to be replaced, thus saving costs.

[0029] Specifically, a first screw hole 13 is provided between adjacent clamps 3, so that the first screw holes 13 are evenly distributed, which helps to ensure the stability and reliability of the fixing between the mounting base 2 and the mounting groove 11.

[0030] In this embodiment, a flange 14 is provided at the end of the rotating shaft 1 away from the mounting groove 11. The drive module of this utility model is installed in the outside through the flange 14, so as to achieve high assembly efficiency.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
