Two limit pins 308 are fixedly connected to the top surface of the fixing plate 302.

[0035] In this embodiment, when machining the inner cavity of the cylinder head 4, the cylinder head 4 is placed on three support blocks 304. The three support blocks 304 and five support seats 307 support the cylinder head 4, and two limiting pins 308 restrict the position of the cylinder head 4 to facilitate the installation of the cylinder head 4. The three hydraulic cylinders 303 are activated, and the hydraulic cylinders 303 extend and drive the pressure block 305 to rotate. The connecting plate 306 is connected to the pressure block 305 and the limiting block respectively to support the pressure block 305. When the pressure block 305 rotates, one end of the pressure block 305 presses the cylinder head 4. The support blocks 304 and the pressure block 305 clamp and fix the cylinder head 4 to facilitate the machining of the inner cavity of the cylinder head 4.

[0036] The height of the five support seats 307 is designed according to the shape of the cylinder head 4, so as to provide stable support for the cylinder head 4.

There are four second hydraulic cylinders 310 arranged in pairs. A pressure block 311 is fixedly connected to the telescopic end of one pair of second hydraulic cylinders 310, and a pressure block 312 is fixedly connected to the telescopic end of the other pair of second hydraulic cylinders 310.
