[0040] Please see Figure 1 and Figure 2 This embodiment proposes a workpiece processing fixture for fixing a workpiece 100 to be processed. It includes a worktable 1, a support 2, a limiting part 3, a pushing part 4, and a holding part 5. The worktable 1 has a processing position for processing the workpiece 100 to be processed. The support 2 is disposed at the processing position and is used to support the workpiece 100 to be processed to a preset height. The limiting part 3 is disposed at the processing position and is located on the outside of the workpiece 100 to be processed. The pushing part 4 is disposed opposite to the limiting part 3 to push the workpiece 100 to be processed to move in a direction close to the limiting part 3, and to keep the workpiece 100 to be processed in contact with the limiting part 3. The holding part 5 is placed at the processing position and can cooperate with the support 2 to clamp the workpiece 100 to be processed.

[0041] Understandably, when the workpiece 100 is placed on the support part 2, it is pushed towards the limiting part 3 by the pushing part 4, and the workpiece 100 is kept in contact with the limiting part 3 to complete the circumferential limiting of the workpiece 100. Then, with the cooperation of the holding part 5 and the support part 2, the height limiting of the workpiece 100 can be completed. Compared with traditional mechanical fixtures that often require manual adjustment and locking, this setting can avoid manual adjustment and locking, thereby improving the positioning accuracy and efficiency of the workpiece 100, thus improving the CNC machining accuracy and efficiency, and also ensuring the stability of the workpiece 100 during the machining process.

[0042] Furthermore, the support part 2 includes multiple support members 21, which are evenly distributed on the bottom of the workpiece 100 to be processed and are detachably connected to the worktable 1. It is understood that the arrangement of the support members 21 enables a certain distance between the workpiece 100 to be processed and the worktable 1, thereby avoiding interference between the workpiece 100 to be processed and the worktable 1 during the processing.

[0043] For example, in this embodiment, the workpiece 100 to be processed is square, and the workpiece 100 to be processed is provided with a flange around its perimeter. Multiple support rods are evenly distributed at the bottom of the workpiece 100 to be processed and can abut against the flange respectively. This arrangement can ensure the stability of the workpiece 100 to be processed during the processing.

[0044] Preferably, the support member 21 is columnar or plate-shaped. By selecting a support member 21 with a suitable shape according to the contact area between the support member 21 and the workpiece 100 to be processed, the applicability of the processing fixture can be further improved.

[0045] In this embodiment, the holding part 5 includes multiple holding components 51, all of which are disposed on the worktable 1 and evenly distributed around the periphery of the workpiece 100 to be processed. The holding end of any holding component 51 can abut against the top of the workpiece 100. It can be understood that, compared to a traditional pressing mechanism, the holding components 51 disposed on the worktable 1 save the height space of the entire processing fixture, making it suitable for CNC equipment of different sizes and models. The multiple holding components 51 can apply downward pressure towards the support member 21 to different positions of the workpiece 100 to be processed, and with the cooperation of the holding components 51 and the support member 21, can apply forces in opposite directions to the workpiece 100 to ensure that the workpiece 100 is subjected to uniform force at all positions during processing, thereby ensuring the stability of the workpiece 100 during processing.

[0046] Preferably, the number of multiple pressing components 51 is set in a one-to-one correspondence with the number of multiple support members 21 to ensure the uniformity of force on all parts of the workpiece 100 to be processed.

[0047] Specifically, the holding assembly 51 includes a holding bracket 511, a holding member 512, and a holding cylinder 513. The holding bracket 511 is disposed on the worktable 1. The middle part of the holding member 512 is hinged to the holding bracket 511. The holding member 512 has a holding state for holding the workpiece 100 to be processed and an open state for releasing the workpiece 100 to be processed. The holding cylinder 513 is disposed on the worktable 1. The piston rod end of the holding cylinder 513 is hinged to one end of the holding member 512. When the piston rod is in the initial state, the holding member 512 is in the open state. When the piston rod is in the extended state, the holding member 512 is in the holding state. It is understandable that the holding member 512 and the holding bracket 511 form a lever structure, and under the action of the holding cylinder 513, the holding member 512 can switch between the holding state and the open state to facilitate the installation and removal of the workpiece 100 to be processed. Specifically, when the workpiece 100 to be processed is placed, the piston rod is in the initial state and the holding member 512 is in the open state. After the workpiece 100 to be processed is placed, the piston rod extends to switch the holding member 512 from the open state to the holding state, thereby completing the positioning of the workpiece 100 in the height direction. The whole process has low manual intervention, thereby improving the positioning efficiency of the workpiece 100 to be processed.

[0048] In this embodiment, the limiting part 3 includes a plurality of limiting members 31, which are arranged along at least two directions on the outer side of the workpiece 100 to be processed. It is understood that the limiting members 31 arranged in different directions can rigidly limit different sidewalls of the workpiece 100 to be processed, thereby further improving the stability of the workpiece 100 during processing. Preferably, the limiting members 31 are existing limiters.

[0049] Correspondingly, the pushing part 4 includes multiple pushing members, each corresponding to a multiple limiting member 31. It can be understood that after the workpiece 100 to be processed is placed on the support part 2, the pushing members can move the workpiece 100 closer to the corresponding limiting member 31, thereby achieving circumferential limiting of the workpiece 100. The pushing member is preferably a linear cylinder.

[0050] In this embodiment, multiple processing positions are provided. This arrangement allows for the simultaneous positioning of multiple workpieces 100 to be processed according to production needs, thereby further improving production efficiency.

[0051] In addition, the workpiece machining fixture also includes a base 6 and a support block 7, with the support block 7 detachably disposed between the base 6 and the worktable 1. It is understood that the worktable 1 is located in the working area of ​​the CNC equipment. The height of the support block 7 is adjusted according to the size and model of the CNC equipment, thereby ensuring that the worktable 1 remains within the working area. This arrangement improves the applicability of the workpiece machining fixture.

[0052] This embodiment also proposes a CNC machining equipment, including the workpiece machining fixture described above. It is understood that with the CNC machining equipment using the aforementioned workpiece machining fixture, the degree of manual intervention during the installation of the workpiece 100 is low, thereby improving the machining efficiency of the workpiece 100.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
