[0033] When the multi-wedge belt is installed on the drum washing machine, due to the relatively high initial installation frequency, it is very difficult to fix the belt 300 by hand during installation. To solve this problem, a tooling 100 for installing the belt 300 is designed. First, place the belt 300 at a general position on the motor shaft head and the pulley 200, then clamp the tooling 100 onto the pulley 200 to fix the position of the belt 300, and then hold the tooling 100 and the pulley 200 and rotate them together to install the belt 300.

[0034] Refer to Figures 1 to 3 , this application proposes a belt assembly tooling, including: a belt clamping structure on the pulley 200 and a positioning structure for positioning the belt clamping structure 1 on the pulley 200. A top column structure 2 is arranged on the side of the belt clamping structure 1. When the belt clamping structure 1 is clamped on the pulley 200, the belt 300 passes through the gap between the pulley 200 and the belt clamping structure 1. By rotating the pulley 200, the top column structure 2 and the belt clamping structure 1 cooperate to push the belt 300 onto the pulley 200 for assembly. In the present invention, the belt clamping structure 1 is installed on the pulley 200, so that the belt 300 passes through the gap between the pulley 200 and the belt clamping structure 1, and then the pulley 200 is rotated. Since the belt 300 is subjected to the thrust under the cooperation of the top column structure 2 and the belt clamping structure 1, after the belt 300 is rotated, the belt 300 is naturally sleeved on the pulley 200; the tooling 100 of the present invention overcomes the inconvenience of manually installing the belt 300 and provides great convenience for the installation of the belt 300.

[0035] When using the tooling 100 of the present invention, the tooling 100 is buckled on the pulley 200, a gap is formed between the tooling 100 and the hub of the pulley 200, and the belt 300 passes through the gap; when the pulley 200 rotates, the pulley 200 turns, so that the belt 300 not installed on the pulley 200 all passes through the gap; the gap provides guidance for installing the belt 300 on the pulley 200, the belt buckle structure 1 and the ejector pin structure 2 push the belt 300, and the belt 300 is thus stressed, enabling the belt 300 to be smoothly installed on the pulley 200; the present invention Figure 2 is the state before the belt 300 is installed on the pulley 200. By rotating the pulley 200, the belt 300 is installed on the pulley 200. For the installed state, refer to Figure 3 .

[0036] After buckling the tooling 100 on the pulley 200, a positioning structure is provided to position the tooling 100 on the pulley 200, so that the reaction force of the belt 300 on the tooling 100 will not cause the tooling 100 to disengage from the pulley 200; the positioning structure includes the first cross bar 3 and the positioning disk 5 for positioning at the center of the pulley 200. The belt buckle structure 1 is connected to the first cross bar 3, and the first cross bar 3 is connected to the positioning disk 5; by positioning the positioning disk 5 at the center of the pulley 200, the entire tooling 100 is positioned on the pulley 200.

[0037] In addition, the positioning structure can also be set to include the first cross bar 3, the second cross bar 4 and the positioning disk 5 for positioning at the center of the pulley 200. The first cross bar 3 and the second cross bar 4 are arranged on the positioning disk 5 at a certain angle; the first cross bar 3 is provided with the first stop block 6, and the second cross bar 4 is provided with the second stop block 7. The first stop block 6 and the second stop block 7 are arranged oppositely, and the first stop block 6 and the second stop block 7 cooperate to clamp the spoke 201 of the pulley 200.

[0038] The first cross bar 3 and the second cross bar 4 are provided. When using the tooling 100 of the present invention, the first cross bar 3 and the second cross bar 4 form a structure similar to a lever. The setting of the second cross bar 4 is beneficial to increasing the moment of the first cross bar 3, so that the setting of the first cross bar 3 and the second cross bar 4 is beneficial to the force balance of the cross bar when the pulley 200 rotates; the way of setting the two cross bars (including the first cross bar 3 and the second cross bar 4) is that the first cross bar 3 and the second cross bar 4 are respectively located on different spokes 201 of the pulley 200, so that the first stop block 6 and the second stop block 7 act on different spokes 201. The first stop block 6 and the second stop block 7 act on different spokes 201, and since they are arranged oppositely, the acting forces of the first stop block 6 and the second stop block 7 are opposite, and further the first cross bar 3 and the second cross bar 4 form a lever structure. Refer to Figure 2 and Figure 3 .

[0039] That is to say, the setting of two cross bars is superior to that of one cross bar in terms of force balance. When setting one cross bar, it can be positioned by fastening the positioning disk 5 at the center of the pulley 200, or the first stop block 6 and the second stop block 7 can be set on both sides of the first cross bar 3 to limit the first cross bar 3. In this way, the first stop block 6 and the second stop block 7 jointly clamp the spoke 201 of the same pulley 200, and the positioning is carried out by clamping the spoke 201 of the pulley 200.

[0040] The belt buckle structure 1 is set as a U-shaped structure, refer to Figure 1 and Figure 5 ; The U-shaped belt buckle structure 1 is sleeved on the pulley 200, and both sides of the U-shaped structure are clamped on the two side rims 202 of the pulley 200. When using the tooling 100 of the present invention, the belt buckle structure 1 is buckled on the pulley 200, and the belt 300 passes through the gap between the belt buckle structure 1 and the pulley 200. The U-shaped structure enables the belt 300 to be stably located in the gap and can prevent the belt 300 from slipping out of the pulley 200.

[0041] The first cross bar 3 and the second cross bar 4 are arranged in cooperation with the spoke 201 of the pulley 200, and the angle between the first cross bar 3 and the second cross bar 4 can be fixedly set so that the first cross bar 3 and the second cross bar 4 cooperate with a certain specific pulley 200. In addition, in order to enable the tooling 100 of the present invention to adapt to different pulleys 200, the first cross bar 3 and the second cross bar 4 are rotatably arranged relative to the positioning disk 5, that is, the first cross bar 3 can rotate around the positioning disk 5, and the second cross bar 4 can rotate around the positioning disk 5. With such a setting, the angle between the first cross bar 3 and the second cross bar 4 becomes adjustable, so that the tooling 100 of the present invention can be applied to different pulleys 200 for installing the belt 300. After the angle between the first cross bar 3 and the second cross bar 4 is adjusted, the first cross bar 3 and the second cross bar 4 can be positioned by screws or other positioning structures, so that the angle between the first cross bar 3 and the second cross bar 4 is temporarily fixed.

[0042] Corresponding slide rails (not marked in the figure) can be set on the positioning disk 5, and the first cross bar 3 and the second cross bar 4 are installed on their respective corresponding slide rails so that the two can move on their respective slide rails to change the included angle between the two. After adjusting the included angle between the first cross bar 3 and the second cross bar 4, it is tightened by a fastening structure, and the fastening structure can be a screw, a bolt or a buckle structure, etc.

[0043] In actual use, there may be pulleys 200 with different diameters. Therefore, when the positioning disk 5 is fastened to the center of the pulley 200, it is necessary to set the tooling 100 that can adjust the distance between the positioning disk 5 and the belt buckle structure 1 so that the tooling 100 can be applied to pulleys 200 with different diameters; the distance between the positioning disk 5 and the belt buckle structure 1 is adjusted by setting an adjusting structure.

[0044] The adjusting structure includes an adjusting bolt 8, a bolt hole 10 provided on the belt clamping structure 1, and a moving hole 9 provided on the first crossbar 3. The belt clamping structure 1 and the first crossbar 3 are stacked and connected. The adjusting screw sequentially passes through the moving hole 9 and the bolt hole 10, and by moving the adjusting screw within the moving hole 9, the distance between the belt clamping structure 1 and the positioning disc 5 is adjusted.

[0045] Specifically, a bolt hole 10 is provided on the belt clamping structure 1, a moving hole 9 is provided on the first crossbar 3, and the first crossbar 3 and the belt clamping structure 1 are connected in a stacked manner, such that the bolt hole 10 is aligned with the moving hole 9. Then, an adjusting screw is passed through the moving hole 9 and the bolt hole 10 from one side of the first crossbar 3, and then tightened to fix the relative positions of the belt clamping structure 1 and the first crossbar 3; when it is necessary to be used for a pulley 200 of another diameter, the adjusting screw is loosened, and the belt clamping structure 1 is moved closer to or farther away from the positioning disc 5 to change the distance between the belt clamping structure 1 and the first crossbar 3, so that the tooling 100 can adapt to pulleys 200 of different diameters.

[0046] In addition, the adjusting structure can also include a slide rail (not marked in the figure) provided on the belt clamping structure 1, a chute provided on the first crossbar 3, and a positioning screw. The slide rail is movably arranged within the chute, and the distance between the belt clamping structure 1 and the positioning disc 5 is adjusted by sliding the belt clamping structure 1 on the first crossbar 3; after the distance between the belt clamping structure 1 and the positioning disc 5 is adjusted, the positional relationship between the belt clamping structure 1 and the first crossbar 3 is tightened to complete the adjustment.

[0047] In addition, in order to ensure the stable connection between the belt clamping structure 1 and the first crossbar 3, a guide rail structure 13 is provided on the belt clamping structure 1, and the first crossbar 3 is stacked and arranged within the guide rail structure 13. When it is necessary to adjust the distance between the belt clamping structure 1 and the positioning disc 5, the first crossbar 3 can be moved within the guide rail structure 13; the setting of the guide rail structure 13 provides guidance for the movement of the first crossbar 3 when adjusting the distance between the belt clamping structure 1 and the positioning disc 5, and avoids the deviation of the first crossbar 3.

[0048] Generally, a large number of magnetic metals are provided on the pulley 200. Therefore, a magnet 11 can be provided on the positioning disc 5, and the magnetic force of the magnet 11 is used to achieve the positioning effect of the positioning disc 5; in the present invention, a magnet 11 is provided on one side of the positioning disc 5 away from the pulley 200, and the magnet 11 generates magnetic adsorption on the metal on the pulley 200, so that the positioning disc 5 increases the positioning effect.

[0049] Existing pulleys 200 usually use hex nuts or hex bolts for fastening at the center. When the pulley 200 uses hex screws, the inner side of the positioning disc 5 can be set as an inner hexagon groove structure 12. Refer toFigure 4 to cooperate with the hexagonal nut or hexagonal bolt on the pulley 200; for example, when a hexagonal nut is used at the center of the pulley 200, the internal hexagonal groove structure 12 of the positioning disk 5 cooperates with the hexagonal nut for assembly to form the cooperation between the internal hexagonal structure and the external hexagonal structure, forming a hexagonal positioning structure form; this kind of cooperation method can avoid setting other positioning structures, and only the positioning disk 5 is needed to fix the workpiece on the pulley 200 regularly, so that the structure of the tooling 100 of the present invention is more simplified.

[0050] In addition, the structural form of the first cross bar 3 of the present invention can be changed according to the spoke 201 structure of the pulley 200. Refer to Figure 1 and Figure 3 , the spoke 201 of the pulley 200 has a certain inclination. The first cross bar 3 is set according to the inclination of the spoke 201 of the pulley 200. The first cross bar 3 is set with one end being an inclined structure and the other end being a horizontal structure. This setting of the first cross bar 3 is only an adaptive setting and does not represent the only structure of the first cross bar 3 in this application; in order to adapt to the spokes 201 of other pulleys 200, the first cross bar 3 can be adjusted accordingly.

[0051] Refer to Figures 1 to 5 , the present application proposes a belt assembly method, using the above belt assembly tooling to assemble the belt on the pulley. The method includes the following steps:

[0052] S101: Perform pre-assembly on the belt and the pulley. The pre-assembly is to partially sleeve the belt on the pulley;

[0053] S102: Positionally install the positioning disk at the center of the pulley;

[0054] S103: Adjust the distance between the belt buckle structure and the positioning disk until the belt buckle structure is tightly buckled on the pulley, so that the belt is positioned in the gap formed between the belt buckle structure and the pulley;

[0055] S104: By rotating the pulley, the ejector pin structure and the belt buckle structure cooperate to push the belt to be assembled on the pulley.

[0056] In the present invention, the belt buckle structure 1 is installed on the pulley 200, the belt 300 passes through the gap between the pulley 200 and the belt buckle structure 1, and then the pulley 200 is rotated. Since the belt 300 is subjected to the thrust under the cooperation of the ejector pin structure 2 and the belt buckle structure 1, after rotating the belt 300, the belt 300 is naturally sleeved on the pulley 200; the tooling 100 of the present invention overcomes the inconvenience of manually installing the belt 300 and provides great convenience for the installation of the belt 300.

[0057] When using the tooling 100 of the present invention, the positioning disk is positioned and installed at the center of the pulley 200. Then, the distance between the positioning disk and the belt buckle structure 1, that is, the length of the first crossbar, is adjusted through the adjustment structure. The tooling 100 is buckled on the pulley 200, and a gap is formed between the tooling 100 and the hub of the pulley 200. The belt 300 passes through this gap. When the pulley 200 rotates, the pulley 200 makes a full circle, so that the belt 300 not installed on the pulley 200 all passes through this gap. This gap provides guidance for installing the belt 300 on the pulley 200. The belt buckle structure 1 and the top column structure 2 push the belt 300, and the belt 300 is thus stressed, enabling the belt 300 to be smoothly installed on the pulley 200. The present invention Figure 2 is the state before the belt 300 is installed on the pulley 200, that is, the pre-assembly state. By rotating the pulley 200, the belt 300 is installed on the pulley 200. For the installed state, refer to Figure 3 .

[0058] In order to enable the tooling 100 of the present invention to adapt to different pulleys 200, the first crossbar 3 and the second crossbar 4 are rotatably arranged relative to the positioning disk 5, that is, the first crossbar 3 can rotate around the positioning disk 5, and the second crossbar 4 can rotate around the positioning disk 5. With such a setting, the angle between the first crossbar 3 and the second crossbar 4 becomes adjustable, so that the tooling 100 of the present invention can be applicable to installing the belt 300 on different pulleys 200. After the angle between the first crossbar 3 and the second crossbar 4 is adjusted, the first crossbar 3 and the second crossbar 4 can be positioned by screws or other positioning structures, so that the angle between the first crossbar 3 and the second crossbar 4 is temporarily fixed.

[0059] Therefore, before step S103, it further includes:

[0060] S1021: Adjust the first crossbar or the second crossbar so that the first crossbar or the second crossbar is positioned on different spokes of the pulley.

[0061] The adjustability of the first crossbar 3 and the second crossbar 4 enables the tooling of the present invention to adapt to pulleys with different spokes. Corresponding sliding rails (not marked in the figure) can be provided on the positioning disk 5. The first crossbar 3 and the second crossbar 4 are installed on their respective corresponding sliding rails, so that the two can move on their respective sliding rails to change the included angle between them. After the included angle between the first crossbar 3 and the second crossbar 4 is adjusted, it is fastened through a fastening structure, and this fastening structure can be a screw, a bolt or a buckle structure, etc.

[0062] The above are only the preferred embodiments of the present invention, and it cannot be determined that the specific implementation of the present invention is limited only to these descriptions. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
