The nut (45) The thread is set on the surface of the bolt (43), the two sets of connecting discs (46) are respectively set on both sides of the nut (45), the two sets of rings (47) are respectively set on one side of the surface of the two sets of connecting discs (46), the two sets of annular grooves (48) are respectively opened on both sides of the surface of the nut (45), the rings (47) are respectively engaged in the interior of a set of corresponding annular grooves (48), the other side of the set of connecting discs (46) near the clamping block (36) is fixedly connected to the clamping block (36), the spring (49) is set on the surface of the bolt (43), and the two ends of the spring (49) are respectively connected to the surface of the fixed seat (35) and the other set of connecting discs (46).

8. The multi-valve cover synchronous clamping device according to claim 1, characterized in that: The support module (5) includes a circular groove (51), a positioning post (52) and a positioning slot (53). The circular groove (51) is located in the middle of the workbench (1). The positioning post (52) is located inside the circular groove (51). The positioning slot (53) is located inside the positioning post (52).

9. A multi-valve cover synchronous clamping device according to claim 8, characterized in that: Each set of clamping blocks (36) has a protective pad (6) on its surface and the inner wall of the positioning groove (53). Each set of protective pads (6) has several sets of strip-shaped protrusions formed on its surface. The several sets of strip-shaped protrusions are evenly arranged at equal intervals.

10. The method of using a multi-valve cover synchronous clamping device according to claims 1-9, characterized in that: Step (A), adjustment of the device; Step (A) includes, Step (A1): Rotate the nut (45). Since the rectangular groove (42) and the rectangular block (44) cooperate to limit the bolt (43), the bolt (43) is prevented from rotating with the nut (45). Thus, the nut (45) moves along the axial direction of the bolt (43) during rotation, thereby driving the connecting discs (46) on both sides and the clamping block (36) to move synchronously. The spring (49) is compressed or released under the action of one of the connecting discs (46). The position of the nut (45) is determined according to the material of the valve cover to be clamped to maintain the initial elastic force of the spring (49). Step (A2): Select the corresponding positioning post (52) according to the size of the valve cover to be clamped, and ensure that the size of the positioning groove (53) on the surface of the positioning post (52) is compatible with the valve cover; Step (A3): Insert the positioning pin (52) into the inside of the circular groove (51); Step (B), positioning of the valve cover; Step (B) includes, Step (B1): Install the valve cover inside the positioning groove (53); Step (B2), start the motor (21), the motor (21) starts to rotate, and the rotation of the motor (21) drives the active turntable (22) to rotate synchronously. The active turntable (22) transmits power synchronously to several sets of driven turntables (23) through the connecting rod (24). The several sets of driven turntables (23) follow the active turntable (22) to rotate synchronously in the same direction and at the same angle. The discs (31) on the active turntable (22) and the driven turntables (23) rotate synchronously. Due to the synchronous rotation of the two sets of moving blocks ( 33) The limiting posts (34) on the surface are respectively engaged in the corresponding slide grooves (32) on the surface of the disc (31). The worktable (1) limits the movement of the two sets of moving blocks (33). The rotation of the disc (31) is transformed into the convergence movement of the two sets of moving blocks (33) along the slide groove (32) through the guiding effect of the slide groove (32), which in turn drives the fixed seat (35) and the clamping block (36) to move towards the valve cover synchronously, and finally makes the two sets of clamping blocks (36) cooperate to clamp and fix the valve cover. Step (C), cushion the valve cover; Step (C) includes, In step (C1), during the clamping process, the clamping block (36) is attached to the surface of the valve cover. The valve cover generates a reverse force on the clamping block (36), thereby pushing the combination of nut (45) and bolt (43) towards the fixed seat (35). The spring (49) is further compressed and generates an elastic restoring force, forming a flexible clamping force on the valve cover, absorbing the impact force during the clamping process and the vibration during processing.
