[0040] Please refer to Figure 1 With Figure 2 The present embodiment proposes a workpiece machining jig for fixing a workpiece to be machined 100, which comprises a workbench 1, a supporting part 2, a limiting part 3, a pushing part 4 and a pressing part 5. The workbench 1 has a machining position for machining the workpiece to be machined 100. The supporting part 2 is arranged at the machining position and is used to support the workpiece to be machined 100 to a predetermined height. The limiting part 3 is arranged at the machining position and is located outside the workpiece to be machined 100. The pushing part 4 is arranged opposite to the limiting part 3 to push the workpiece to be machined 100 to move in the direction of approaching the limiting part 3, and can keep the workpiece to be machined 100 in abutment with the limiting part 3. The pressing part 5 is arranged at the machining position, and the pressing part 5 can cooperate with the supporting part 2 to clamp the workpiece to be machined 100.

[0041] It can be understood that the workpiece to be machined 100 is placed on the supporting part 2, and then under the action of the pushing part 4, the workpiece to be machined 100 can be pushed to approach the limiting part 3, and the workpiece to be machined 100 can be kept in abutment with the limiting part 3 to complete the circumferential limiting of the workpiece to be machined 100. Then, under the cooperation of the pressing part 5 and the supporting part 2, the limiting of the workpiece to be machined 100 in the height direction can be completed. Compared with the traditional mechanical clamp which often needs to be manually adjusted and locked, such arrangement can avoid manual adjustment and locking, so as to improve the positioning accuracy and efficiency of the workpiece to be machined 100, thereby improving the CNC machining precision and efficiency, and also ensuring the stability of the workpiece to be machined 100 during machining.

[0042] Further, the supporting part 2 comprises a plurality of supporting pieces 21, which are uniformly distributed at the bottom of the workpiece to be machined 100 and are detachably connected with the workbench 1. It can be understood that the arrangement of the supporting pieces 21 can make the workpiece to be machined 100 have a certain distance from the workbench 1, so as to avoid interference between the workpiece to be machined 100 and the workbench 1 during machining.

[0043] Exemplarily, the embodiment is described taking the square workpiece 100 as an example, and the workpiece 100 is provided with a flange at the periphery, and the plurality of supporting rods are uniformly distributed on the bottom of the workpiece 100 and can respectively abut against the flange. In this way, the stability of the workpiece 100 during the machining process can be ensured.

[0044] Preferably, the supporting member 21 is columnar or plate-shaped. According to the contact position of the supporting member 21 with the workpiece 100, the supporting member 21 with a corresponding shape is selected, so as to further improve the applicability of the machining jig.

[0045] In the embodiment, the pressing part 5 includes a plurality of pressing assemblies 51, which are arranged on the workbench 1 and are uniformly distributed on the periphery of the workpiece 100. The pressing end of any pressing assembly 51 can abut against the top of the workpiece 100. It can be understood that, compared with the traditional downward pressing mechanism, the arrangement of the pressing assembly 51 on the workbench 1 can save the height space of the entire machining jig, so as to adapt to CNC equipment of different sizes and models. The plurality of pressing assemblies 51 can apply a downward pressing force to different positions of the workpiece 100 to approach the supporting member 21, and can apply an action force in the opposite direction to the workpiece 100 under the cooperation of the pressing assembly 51 and the supporting member 21, so as to ensure that the force on each position of the workpiece 100 during the machining process is uniform, thereby ensuring the stability of the workpiece 100 during the machining process.

[0046] Preferably, the number of the plurality of pressing assemblies 51 corresponds to the number of the plurality of supporting members 21 one by one, so as to ensure the uniformity of the force on the workpiece 100.

[0047] Specifically, the pressing assembly 51 comprises a pressing support 511, a pressing piece 512, and a pressing cylinder 513. The pressing support 511 is arranged on the workbench 1. The middle part of the pressing piece 512 is hinged to the pressing support 511, and the pressing piece 512 has a pressing state for pressing the workpiece 100 and an open state for releasing the workpiece 100. The pressing cylinder 513 is arranged on the workbench 1, and the piston rod end of the pressing cylinder 513 is hinged to one end of the pressing piece 512. When the piston rod is in the initial state, the pressing piece 512 is in the open state. When the piston rod is in the extended state, the pressing piece 512 is in the pressing state. It can be understood that the pressing piece 512 and the pressing support 511 form a lever structure, and under the action of the pressing cylinder 513, the pressing piece 512 can be switched between the pressing state and the open state, so as to facilitate the installation and removal of the workpiece 100. Specifically, when the workpiece 100 is placed, the piston rod is in the initial state, and the pressing piece 512 is in the open state. After the workpiece 100 is placed, the piston rod is elongated to switch the pressing piece 512 from the open state to the pressing state, so as to complete the positioning of the workpiece 100 in the height direction. The whole process has low artificial participation, so as to improve the positioning efficiency of the workpiece 100.

[0048] In the embodiment, the limiting part 3 comprises a plurality of limiting pieces 31 arranged on the outside of the workpiece 100 in at least two directions. It can be understood that the limiting pieces 31 arranged in different directions can hard-limit different side walls of the workpiece 100, so as to further improve the stability of the workpiece 100 during processing. Preferably, the limiting piece 31 is a limiter in the prior art.

[0049] Correspondingly, the pushing part 4 comprises a plurality of pushing pieces, which are arranged one by one corresponding to the plurality of limiting pieces 31. It can be understood that after the workpiece 100 is placed on the supporting part 2, under the action of the pushing piece, the workpiece 100 can be close to the corresponding limiting piece 31, so as to complete the circumferential limiting of the workpiece 100. Preferably, the pushing piece is a linear cylinder.

[0050] In the embodiment, a plurality of processing positions are arranged. In this way, the plurality of workpieces 100 can be positioned simultaneously according to production needs, so as to further improve the production efficiency.

[0051] In addition, the workpiece processing jig further comprises a base 6 and a supporting block 7, which is detachably arranged between the base 6 and the workbench 1. It can be understood that the workbench 1 is arranged in the working area of the CNC equipment. According to the different sizes and models of the CNC equipment, the height of the supporting block 7 is adjusted, so that the workbench 1 can be kept in the working area. In this way, the applicability of the workpiece processing jig can be improved.

[0052] The embodiment also provides a CNC machining device comprising the workpiece machining jig.
