[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] See also Figure 1 to Figure 2 As shown: This is a novel clamp for CNC machining, including a base 1, a swing adjustment component 2, a rotation adjustment component 3 and a clamping table component 4. Among them: the swing adjustment component 2 can be swingably set on the base 1, and is used to swing the workpiece back and forth in the horizontal direction to adjust the angle; the rotation adjustment component 3 can be rotatably set on the swing adjustment component 2, and is used to rotate the workpiece in the vertical direction to adjust the angle; the clamping table component 4 is fixed at the output end of the rotation adjustment component 3; the rotation adjustment component 3 can drive the clamping table component 4 to rotate. Specifically: during machining, after the clamping table component 4 completes the clamping of the workpiece to be machined, the swing adjustment component 2 and the rotation adjustment component 3 coordinate to adjust the valve seat to the plane to be machined, and then the machining starts with a CNC machine tool. When different planes need to be machined, they can be adjusted by the swing adjustment component 2 and the rotation adjustment component 3. By using swing adjustment components and rotary adjustment components to coordinate to the processing position and then the machine tool starts processing, the processing process of the entire fixture assembly is compact (only clamping can complete the face milling, drilling, tapping and cross hole operations of the valve seat), with less equipment investment, short and balanced processing cycle, low scrap rate, low labor cost, and improved manufacturing efficiency.

[0024] Based on the above embodiment, the bottom array of the base 1 is provided with a strong magnet for providing suction force for fixing on the machine tool, so that it can be firmly fixed on the machine tool during the processing without deviation, so as to ensure the processing accuracy requirements.

[0025] Based on the above embodiment, the swing adjustment component 2 includes a first driving source 21 fixed on the base 1 to provide power; a swing table 22 is provided on one side of the first driving source 21 for movement; the first driving source 21 can drive the swing table 22 to swing back and forth, so that it can be adjusted at a larger angle in the XY plane, ensuring a suitable processing direction and improving manufacturing efficiency.

[0026] Based on the above embodiment, the first driving source 21 is a servo motor, which is mounted on the frame through a motor mounting plate; the output end of the servo motor is connected to a worm gear; the output end of the worm gear is fixedly connected to the swing table 22. During operation, the servo motor adjusts the angle through the pulse signal sent by the controller, so that the swing table 22 swings to a suitable position along the horizontal direction, which is convenient for processing efficiency.

[0027] On the basis of the above embodiment, a through rectangular mounting hole is provided on the swing table 22 to provide space for the installation of the rotating adjustment component 3, so that the whole structure is more compact; the rotating adjustment component 3 is fixed on the rectangular mounting hole, and the coaxial bearing at the other end of the swing table 22 can be rotatably mounted on the base 1, which is used to position and support the swing table 22 to prevent displacement during the swinging process.

[0028] Based on the above embodiment, the rotation adjustment component 3 includes a second servo motor; a second worm gear is provided at the output end of the second servo motor; and a T-shaped mounting platform is fixed on the worm gear.

[0029] Based on the above embodiment, the clamping platform component 4 includes a mounting base 41; a clamping platform 42 is vertically fixed on the mounting base 41; clamping components 43 are arranged in a triangular shape on the clamping platform 42; and adjustment columns 44 are adjustably installed between adjacent clamping components 43.

[0030] Based on the above embodiment, the pressing component 43 includes a driving cylinder 431; a pressing arm 432 is swingably provided on one side of the driving cylinder 431; the driving cylinder 431 can drive the pressing arm 432 to swing and press the workpiece to fix it.

[0031] Based on the above embodiment, the adjustment column 44 includes an adjustment base 421 fixed on the clamping platform 42 ; a rotation shaft 422 is screwed onto the adjustment base 421 .

[0032] Specifically, during operation, the rotating shaft 422 is adjusted to its position on the adjusting base 421 so that it can support other parts of the valve seat, and then the pressing arm 432 is driven to swing and press the workpiece to fix it under the action of the driving cylinder 431 to ensure that no deformation occurs during the processing. Then, after the adjusting component and the rotating adjusting component are coordinated to the processing position, the machine tool starts processing, so that the processing process of the entire fixture assembly is compact (as long as the clamping is carried out in sequence, the valve seat can be face milled, tapped, and cross-holed), with low equipment investment, short and balanced processing cycle, low scrap rate, low labor cost, and improved manufacturing efficiency.
