[0020] As Figure 1 , Figure 2 and Figure 3 shown, a fixture for mechanical processing that can prevent workpiece damage proposed by the present invention includes a mounting frame 1. A front convex plate 101 is fixedly provided on the front side of the mounting frame 1. Side vertical plates 102 are fixedly provided on both sides of the mounting frame 1. A rear vertical plate 103 is fixedly provided on the rear side of the mounting frame 1. It further includes a placing mechanism 2 and a clamping mechanism 3. A chute 104 is provided in the upper parts of the mounting frame 1 and the front convex plate 101. The placing mechanism 2 includes a placing table 201, and the placing table 201 is slidably connected to the chute 104. A buffer assembly 4 is provided on the rear vertical plate 103. The clamping mechanism 3 is arranged on the side vertical plates 102. The clamping mechanism 3 includes a telescopic rod 301 and a connecting box 302. The telescopic rod 301 is arranged on the side vertical plate 102, and the connecting box 302 is fixedly connected to the end of the movable end of the telescopic rod 301. A buffer assembly 4 is also provided inside the connecting box 302.
[0021] As Figure 1 , Figure 2 and Figure 3 shown, the clamping mechanism 3 further includes a connecting plate 303. The fixed end of the telescopic rod 301 is fixedly connected to the side vertical plate 102. The movable end of the telescopic rod 301 is slidably connected to the side vertical plate 102 and penetrates through the side vertical plate 102. The connecting plate 303 is slidably connected to the inner side of the connecting box 302. A guiding strip 305 is provided at the sliding connection between the connecting plate 303 and the connecting box 302. A clamping plate 306 is fixedly provided on the outer side of the connecting plate 303.
