[0031] Vibration damping device for PC component vibratory casting platform, such as Figs. 1-3 As shown, the device includes a vibration damping seat 10 for processing PC components. Support legs 20 are installed at both ends of the bottom of the vibration damping seat 10. Several sets of locking screws 30 are installed on the outer wall of the vibration damping seat 10. A positioning slot 11 for placing a PC component vibration casting platform 40 is provided on the top of the vibration damping seat 10. A vibration damping sleeve 12 is installed on the inner wall of the positioning slot 11. The number of locking screws 30 is the same as the number of positioning slots 11, and their positions correspond. The locking screws 30 pass through the side wall of the vibration damping seat 10 and extend into the positioning slot 11. A turntable 31 and a fixed clamping plate 32 are coaxially connected to both ends of the locking screws 30, respectively. A groove 13, matching the size of the fixed clamping plate 32 and engaging with it, is provided on the inner wall of each positioning slot 11. The vibration damping seat 10, with its support legs 20 at both ends, provides support for the entire device. Provides stable support; several sets of locking screws 30 installed on the outer wall of the shock absorber 10 are the same number and corresponding in position as the positioning slots 11, ensuring that the PC component vibration casting platform 40 is firmly fixed in the positioning slots 11; the shock absorber sleeve 12 installed on the inner wall of the positioning slots 11 effectively reduces the impact of vibration generated during vibration casting on the PC component; the locking screws 30 pass through the side wall of the shock absorber 10 and extend into the positioning slots 11, and their two ends are coaxially connected to the turntable 31 and the fixed clamping plate 32, respectively. By rotating the turntable 31, the fixed clamping plate 32 can be driven to clamp the PC component. The grooves 13 opened on the inner wall of each set of positioning slots 11 are adapted to the size of the fixed clamping plate 32 and fit together, so that the fixed clamping plate 32 can be stored, making the inner wall of the positioning slot 11 flush with the surface of the fixed clamping plate 32.

[0032] Furthermore, an internal threaded seat 14 for fixing the locking screw 30 is installed on the outer wall of the shock absorber 10, so that the locking screw 30 can be firmly installed on the shock absorber 10, thereby enhancing the connection strength between the locking screw 30 and the shock absorber 10, and thus improving the stability and reliability of the entire shock absorber device.

[0033] Specifically, each set of outriggers 20 is equipped with a fixed foot 21 at the bottom. The fixed foot 21 is connected to the support base 20 in an inverted T-shape.
