The side baffles 3 and the stoppers 5 work together to press the product body placed on the lifting plate 8 The product body 9 plays a lateral limiting and protective role. The fixing block 2 is used to lock the side baffle 3 and fix it on the bottom plate 1. Its main function is to provide an installation position for the side baffle 3, ensuring that the side baffle 3 can be stably fixed on the bottom plate 1, thereby providing reliable lateral support for the product body 9. The side baffle 3 is used to support and fix the top surface stopper 5, which can effectively prevent the product body 9 from lateral deviation during the processing, ensuring the processing accuracy and quality. The stopper 5 further enhances the limiting effect of the product body 9 and is used to position and block the product. The stopper 5 can prevent the product body 9 from jumping in the vertical direction, ensuring that the product always maintains a stable position during the processing. The lifting cylinder 4 can realize the rise and fall of the lifting plate 8 through the telescopic movement of the cylinder. During the processing of the product body 9, when the product body 9 needs to be lifted for specific processing operations, the lifting cylinder 4 can provide enough force to lift the product body 9 smoothly. The lifting plate 8 is connected to the lifting cylinder 4 by bolts to ensure the firmness of the connection. The function of the lifting plate 8 is to carry the product body 9. Its surface is usually specially treated to ensure that the friction between it and the product body 9 is moderate, which can stably support the product body 9 without causing damage to the product surface. When using the upper jig, first place the product body 9 on the lifting plate 8, and then, according to the requirements of the processing technology, the lifting cylinder 4 is started, and the output end of the lifting cylinder 4 extends upward to push the lifting plate 8 to rise, thereby lifting the product body 9 to the required height. During the processing, the side baffle 3 and the block 5 can effectively limit the position of the product body 9, ensuring that the product always remains in the correct position for precise CNC processing operations. After the processing is completed, the output end of the lifting cylinder 4 retracts, and the lifting plate 8 descends, and the product body 9 is put back in place for subsequent operations or taking out the product.

When the product body 9 is placed on the lifting plate 8, the product body 9 can determine its own position by contact with the reference positioning block 6, thereby achieving fast and accurate positioning, effectively preventing the product body 9 from sliding off the lifting plate 8 during processing, making the product body 9 more stable during processing, and two side positioning blocks are installed on the inner side baffle 3. The surface positioning block 7 and the side positioning block 7 are located on the side of the side baffle 3 close to the product body 9. The two side positioning blocks 7 can be set to laterally position the product body 9 from two different positions. The outer surface of the product body 9 fits with the side positioning block 7, so that the product body 9 is more accurately positioned and fixed in the lateral direction. The side positioning block 7 cooperates with the reference positioning block 6 to ensure that the position of the product body 9 in the jig is accurate, providing reliable positioning guarantee for CNC processing. When placing the product body 9, the inner side of the tapered stopper 5 can guide the product body 9 to enter the correct position more smoothly, reducing the error and difficulty when placing the product. At the same time, the tapered design can also adapt to product bodies 9 of different sizes to a certain extent, improving the versatility of the jig and making the product body 9 more convenient when positioning.
