[0026] This application discloses an auxiliary clamping fixture for cooling and vibration reduction, including a box body 6 and an auxiliary plate 7. The box body 6 includes a bottom plate 61 and a side plate 62. The auxiliary plate 7 is located inside the box body 6 and is slidably connected to the side plate 62 of the box body 6. In some other embodiments, the side plate 62 of the box body 6 is provided with a slide rail, and the auxiliary plate 7 is provided with a slider that is slidably connected to the slide rail. The auxiliary plate 7 is provided with a positioning component 8 for positioning the workpiece. The bottom plate 61 inside the box body 6 is provided with a plurality of cylinders 9. In this embodiment, the number of cylinders 9 is preferably 15, and a spring 10 is provided inside each cylinder 9.
