[0020] Example 1

[0021] The main body is composed of a vertical mounting plate 12 and a bottom plate 11. The two ends of the bottom plate 11 are respectively welded to the vertical mounting plates 12. One of the vertical mounting plates 12 is positioned and connected to the positioning plate 3 through a cylindrical pin 4 and a diamond pin 6. The other vertical mounting plate 12 is also positioned and installed with a reserved positioning plate 5 through a cylindrical pin 4 and a diamond pin 6. The diameter of the positioning plate 3 is different from that of the reserved positioning plate 5, which is used to position products of different sizes.

[0022] The positioning plate 3 and the reserved positioning plate 5 are fixedly connected to the vertical mounting plate 12 by installing screws 9. A positioning groove 31 is provided on the positioning plate 3 and the reserved positioning plate 5, and a limiting hole is provided on the bottom of the positioning groove 31. The product to be processed 100 passes through its reserved hole through the limiting pin 2 and is connected to the limiting hole 31 provided on the positioning plate 3 to limit the degree of freedom of the product to be processed 100. The installation of the product to be processed 100 on the reserved positioning plate 5 is similar to the above. The reserved limiting pin 9 is used to limit the installation of the product to be processed 100. In order to increase the positioning stability of the product to be processed 100 to ensure the processing accuracy, the product to be processed 100 is connected to the vertical mounting plate 12 by the positioning screw 121.

[0023] The center position of the base plate 11 of the present application is installed on the workbench 111 of the product to be processed through a center positioning pin 71 and a retaining ring 72, and the two ends of the base plate 11 are fixedly installed with the workbench 111 of the product to be processed by bolts 74 and connecting screws 73 respectively.

[0024] The utility model fixes two positioning plates of different diameters by means of a cylindrical pin 4 and screws on a vertical mounting plate 12, and selects and installs the positioning plates on corresponding positioning plates according to the sizes of different products to be processed, or replaces the positioning plates adapted to the products, thereby increasing the applicable scope of the positioning fixture;

[0025] During processing, the staff places the product to be processed 100 into the corresponding positioning groove 31 of the positioning plate 3, and uses the limit pin 2 to insert from the reserved hole on the product into the limit hole on the bottom of the positioning groove 31 to quickly limit the position of the product to be processed, and then passes through the positioning plate 3 and the vertical mounting plate 12 through the positioning screw 121 to connect the product to be processed with the vertical mounting plate 12, thereby enhancing the fixing stability of the product to be processed, allowing the product to be processed stably and ensuring the processing accuracy. In the process of positioning the product to be processed 100, the staff only needs to quickly position and install the product on the positioning plate 3 without the need for manual calibration again, which greatly saves product positioning time and improves product processing efficiency.
