The bottom end of the fixing structure 2 is provided with a plurality of support parts 201 for supporting workpieces, and the fixing structure 2 is provided with positioning parts 202 for snapping and positioning workpieces. The support parts 201 and the positioning parts 202 are symmetrically disposed on opposite sides of the fixing structure 2.

[0025] Furthermore, both the base 1 and the fixing structure 2 are plate-like structures with a certain thickness, and both are made of casting material. The base 1 and fixing structure 2 are an integral structure, with the fixing structure 2 located in the middle of the base 1 and perpendicular to it. The vertical direction of the fixing structure 2 is the same as the width direction of the base 1. The base 1 on both sides of the fixing structure 2 has the same width. Several support parts 201 are located at the bottom of the fixing structure 2 to support the workpiece clamped on it. Positioning parts 202 are located on the surface of the fixing structure 2, achieving workpiece positioning and ensuring the stability of the workpiece on the fixing structure 2. Additionally, the support parts 201 and positioning parts 202 are located on both sides of the fixing structure 2, thus achieving double-sided clamping of the workpiece. When the workpiece is small, multiple workpieces can be clamped using the positioning parts 202, thereby improving workpiece clamping efficiency and increasing the number of workpieces that can be clamped.

[0026] Several support parts 201 are disposed at the junction of the fixed structure 2 and the base 1, and the support parts 201 are disposed along the length direction of the fixed structure 2. Furthermore, the support parts 201 extend to both sides along the vertical direction of the fixed structure 2. In this embodiment, three support parts 201 are disposed, and the three support parts 201 are distributed along the length direction of the fixed structure 2. Specifically, the three support parts 201 are respectively disposed at both ends and the middle of the bottom of the fixed structure 2, and the support parts 201 realize the support function for the workpiece.

[0027] The positioning part 202 includes a plurality of bottom positioning members 2021, a plurality of middle positioning members 2022, and a plurality of top positioning members 2023 arranged sequentially from bottom to top along the height direction of the fixed structure 2. The plurality of bottom positioning members 2021, the plurality of middle positioning members 2022, and the plurality of top positioning members 2023 are all evenly distributed along the length direction of the fixed structure 2. Further, the plurality of bottom positioning members 2021 are arranged at the bottom of the fixed structure 2, the plurality of middle positioning members 2022 are arranged at the middle of the fixed structure 2, and the plurality of top positioning members 2023 are arranged at the top of the fixed structure 2, and the plurality of middle positioning members 2022 are equidistant from the plurality of bottom positioning members 2021 and the plurality of top positioning members 2023. In addition, the plurality of bottom positioning members 2021, the plurality of middle positioning members 2022, and the plurality of top positioning members 2023 are all arranged to extend to both sides along the vertical direction of the fixed structure 2, and the extension length is less than the extension length of the support part 201. At the same time, the plurality of bottom positioning members 2021 are located at the junction of the support part 201 and the fixed structure 2.

[0028] In this embodiment, three of each of the several bottom positioning members 2021, several middle positioning members 2022, and several top positioning members 2023 are provided, and the three bottom positioning members 2021, three middle positioning members 2022, or three top positioning members 2023 are distributed along the length direction of the fixing structure 2. Specifically, the three bottom positioning members 2021, three middle positioning members 2022, or three top positioning members 2023 are respectively provided at both ends and the middle part of the fixing structure 2. 23 achieves the clamping and positioning of the workpiece, improving the stability of the workpiece on the fixed structure. In addition, when the workpiece is small, different workpieces are clamped separately by several bottom positioning parts 2021, several middle positioning parts 2022 and several top positioning parts 2023, thereby increasing the number of workpieces clamped by the fixed structure 2. At the same time, several bottom positioning parts 2021, several middle positioning parts 2022 and several top positioning parts 2023 can also provide support for smaller workpieces, ensuring the support and fixation of smaller workpieces and improving the stability of clamping smaller workpieces.

[0029] Weight reduction grooves 203 are formed on several bottom positioning members 2021, several middle positioning members 2022 and several top positioning members 2023. Furthermore, the weight reduction grooves 203 are located in the middle of several bottom positioning members 2021, several middle positioning members 2022 and several top positioning members 2023, and the weight of the positioning part 202 is reduced by the weight reduction grooves 203.

[0030] The fixed structure 2 has a plurality of hollow grooves 205 for weight reduction, and the hollow grooves 205 are arranged on opposite sides of the fixed structure 2. Furthermore, a plurality of through portions 204 for weight reduction are formed in the middle of the fixed structure 2. By setting the plurality of hollow grooves 205 and the plurality of through portions 204, the weight of the entire tooling is reduced, thereby ensuring that the tooling is installed on the machine tool, the machine tool can bear the weight of the tooling, and the machine tool can operate.

[0031] The base 1 is provided with a plurality of mounting holes 101 for mounting the base 1. The plurality of mounting holes 101 are arranged in an array on the base 1 and are arranged through the base 1. Furthermore, the base 1 is mounted on the machine tool through the plurality of mounting holes 101. At the same time, the plurality of mounting holes 101 are distributed in an array on the base 1 to ensure the stability of the entire tooling after installation.

[0032] All mounting holes 101 are countersunk holes. Furthermore, when the bolts fix the base 1 to the machine tool through the mounting holes 101, the countersunk holes ensure that the bolts will not leak out of the mounting holes 101, thereby ensuring the smoothness of the surface of the base 1 and preventing the bolts from bumping into the workpiece clamped on the fixed structure 2.
