detailed description

Below in conjunction with specific embodiment and accompanying drawing, the present invention is further described:

Example 1

As shown in Figure 1, the press-fitting equipment 1 includes a workbench 2, a center positioning ring 3, an oil cylinder 4 and a press-fit plate 5. The center of the loading plate 5 and the tail end of the oil cylinder 4 are threadedly connected with the pressing plate 5, and the oil cylinder 4 can drive the pressing plate 5 to do linear reciprocating motion.

As shown in Figure 2, the hoisting equipment includes a hoisting handle 6, a compression shield 7, a guide hole 8 and a claw device 9. The compression shield 7 is provided with four guide holes 8, and the guide holes 8 are used to position the tire , so that the tire can be accurately pressed into the wheel core, the upper part of the compression guard 7 is provided with a hoisting handle 6, and the outer side of the lower part of the compression guard 7 is provided with a claw device 9.

As shown in Figure 3 and Figure 4, the pre-installed gland 10 is divided into 24 position intervals on average, each position interval corresponds to a rubber block, and the distance between the rubber blocks is guaranteed by the pre-installed gland limit block 11, the limit The block 11 is installed on the lower side of the end of the pre-installed gland 10, and is threadedly connected with the pre-installed gland 10, and the curvature of the installation surface fits.

A kind of assembling process of elastic wheel of the present embodiment, its steps are:

Step 1: Lift the wheel core to the workbench 2 of the press-fitting equipment 1, and ensure the correct position of the wheel core through the center positioning ring 3, so that the wheel core and the oil cylinder 4 are in the same axial position and on the cross center line of the wheel core Install positioning guide rods in four threaded holes divided equally by 90 degrees;

Step 2: Hoist the tire on the installation platform, install the pre-installed gland 10 and 24 rubber blocks into the corresponding position of the tire according to the position of the pre-installed gland limit block 11, and fix them;

Step 3: Start the hoisting equipment, place the tire with the pre-installed gland 10 and the rubber block in the compression shield 7, use the three claw devices 9 to support the bottom of the tire, and use the special lifting tool to pass the pressure. The hoisting handles 6 on both sides of the tight shield 7 lift the entire compression shield 7 and the wheel hoop, place them above the wheel core, slowly put down the compression shield 7 and the wheel hoop, and make the four positioning wheels installed on the wheel core The guide rod passes through the four guide holes 8 on the compression shield 7, and lubricant is applied to the part where the rubber block contacts the wheel core;
