Preferably, the upper surface of the first layer slider 13 is machined with a symmetrical boss and is specially hardened, the symmetrical boss is arranged at 90 degrees with respect to the lower boss, the roller 121 in the second layer rolling body 15 is placed on the boss, the upper end of the first layer slider 13 is provided with a fixed guide groove block which is connected with a return spring 125 on one side of the second layer rolling body 15, and a guide rod 124 on one side of the second layer rolling body 15 also passes through the guide groove block. The second-layer rolling bodies 15 can thus roll in the Y direction (shown in fig. 4) on the first-layer slider 13.
Preferably, the second layer slider 16 is made of cemented carbide, a symmetrical boss is machined on the lower surface of the second layer slider, and the second layer slider is placed on the roller 121 in the second layer rolling body 15, a fixed guide groove block is arranged at the lower end of the second layer slider 16 and is connected with the return spring 125 at the other side in the second layer rolling body 15, and the guide rod 124 at the other side in the second layer rolling body 15 also passes through the guide groove block. The second-layer slider 16 is thus movable in the Y direction (shown in fig. 4) simultaneously with the second-layer rolling bodies 15 by twice the stroke of the second-layer rolling bodies 15.
Preferably, a long hole is formed in the side surface of the second layer slider 16, and the length of the long hole is equal to the sliding travel of the second layer slider 16. The stroke positioning screw 14 passes through a long hole on the side surface of the second-layer sliding block 16 and is screwed into a threaded hole on the side surface of the first-layer sliding block 13. In this way, the second-layer slider 16 and the first-layer slider 13 are not separated from each other in the vertical direction with the second-layer rolling element 15 interposed therebetween, and the stroke is controlled in the Y direction (shown in fig. 4).
The two-layer bidirectional two-dimensional adjusting mechanism consisting of the base 11, the first layer rolling bodies 12, the first layer sliding blocks 13, the second layer rolling bodies 15, the second layer sliding blocks 16 and the like can follow sliding when the ingot mould 2 is heated and expanded, the ingot mould 2 can synchronously follow sliding when being cooled and contracted, and the two-dimensional adjusting mechanism can return to an initial position when the ingot mould 2 is replaced. Because the two-dimensional adjusting mechanism works in a way of rolling bodies rolling, the friction resistance of the system is extremely small. The above structure meets the use conditions of the thermal expansion and the cooling contraction of the ingot mould 2.
The third layer lifting deflection system consisting of the top plate 17, the lifting plate spring 18 and the knuckle bearing 20 is formed into a whole through the positioning shaft 19 and the top thread handle of the second layer sliding block 16, and can slide along with the whole two-dimensional adjusting mechanism in the X direction and the Y direction. The working compression stroke of the lifting plate spring 18 is reserved between the top plate 17 and the second layer sliding block 16, and the working compression stroke is also the lifting stroke of the bearing platform 1. Gaps are reserved on the peripheral side surfaces of the top plate 17 and the second-layer sliding block 16, and the deflection angle of the knuckle bearing 20 determines the deflection angle of the bearing platform 1. When the ingot mould 2 is replaced, the impact force of the ingot mould 2 to the system can be buffered, and in addition, the function of leveling and correcting the surface height of the ingot mould 2 can be achieved through the stress balance of the lifting plate spring 18 when the surface of the ingot mould 2 is uneven after turning.
The self-adaptive bearing system for the ingot mould comprises the bearing platform 1 and the bracket 3 as shown in fig. 1, wherein the ingot mould 2 is placed on the bearing platform 1, and the bearing platform 1 is fixedly arranged on the bracket 3 through bolts.
