[0031] In the above description, when the tail of the Z-shaped pressure plate is pressed on the top of the support block, the reducer housing at both ends of the axle housing can be pressed tightly.

[0032] In the above description, lifting rings are provided around the base for transporting tooling.

[0033] Working principle:

[0034] There is a fixed support seat 4 on the right side of the tooling, with two main support fixed support rods 5 on it. These two fixed supports are two main supports, which can support the reduction mechanism housing on the right side of the bridge housing.

[0035] When the workpiece presses down the two linkage support rods, the linkage support rods are first linked and leveled. After leveling, due to the mutual downward pressure of the support rods 3 on both sides, the internal linkage device stops working, and the entire linkage mechanism becomes a rigid body, which plays the role of supporting the left reduction housing.

[0036] The two main supports on the right and one linkage support (two linkage support rods) on the left hold up the reduction mechanism housing at both ends of the entire low-floor support bridge, serving as the main load-bearing for the large volume and mass at both ends.

[0037] The cross-ribbed plate features auxiliary support components. The internal cavity of the auxiliary support cylinder supports houses a coil spring. A manual auxiliary support rod compresses the spring, allowing for up and down movement within a certain range. It automatically adjusts to the workpiece opening, ensuring a tight fit. The operator doesn't need to manually adjust the fulcrum during this fitting process. The side manual tightening bolts are then tightened appropriately, with the bolt rod heads pressing against the manual auxiliary support rods, securing them as an incompressible rigid body. The support rods support the floor bridge's opening bottom surface, providing intermediate support.

[0038] Movable pressure plates and V-shaped pressure plates are used to fix low-floor bridges.

[0039] The above-mentioned supporting and clamping mechanism is used to clamp the improved one-piece casting workpiece, which solves the clamping problems caused by the large span, large mass on both sides and easy deformation of the improved workpiece; it provides a basis for achieving the goals of one-time clamping, overall processing, improved efficiency, and reduced number of tooling and costs.

[0040] The utility model solves the deformation problem caused by the large span of the workpiece and the large mass on both sides. By setting a linkage mechanism, it can not only level the reducer housing on the left side, but also play a supporting role. It is flexible to use, simple to operate, improves work efficiency, reduces construction difficulty, and is easy to promote.
