[0021] Please refer to Figure 1-3 A casting processing fixture with a pull-down clamping and fixing method includes a base plate 1, 15 cylinders 2 and clamping parts 3 with the same number as the cylinders 2. The 15 cylinders 2 are arranged in 3 rows, with 5 in each row. The cylinders 2 are installed at the bottom of the base plate 1, and the clamping parts 3 are installed at the top of the base plate 1. The output shafts of the cylinders 2 pass through the base plate 1 and are connected to the clamping parts 3. The cylinders 2 and clamping parts 3 in the same row are arranged at equal intervals. A workstation 4 is formed between two adjacent clamping parts 3 in the same row. There are a total of 12 workstations 4, which can clamp up to 12 castings 9 at the same time.

[0022] In the above embodiment, there are 12 workstations 4 on the fixture, that is, the fixture can assemble up to 12 castings 9, and the processing equipment can process up to 12 castings 9 at a time. There is no need to frequently stop the machine to load and unload the castings 9, which increases the processing efficiency of the castings 9.
