[0039] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] In the manufacturing process of washing machines, the positioning of the drum component is a crucial step. Traditional positioning devices consist of process plates with positioning pads. However, traditional positioning pad designs often lack flexibility and struggle to adapt to the rapid switching requirements of different models, which not only affects production efficiency but also increases manufacturing costs. Existing common solutions involve directly replacing the process plate for the corresponding model, which is time-consuming and labor-intensive. Therefore, to address this problem, this invention provides a positioning device that can quickly switch between and adapt to different washing machine models.

[0041] Please refer to the following: Figures 1 to 7 As shown, the positioning device 100 adapted to various washing machine drum components provided by this utility model includes a support plate 1, a fixing pad assembly 2, and an adjusting pad assembly 3; wherein, the fixing pad assembly 2 is fixed on the support plate 1 and is used to position a first type of washing machine drum component; the adjusting pad assembly 3 is detachably mounted on the fixing pad assembly 2 and is used to cooperate with the fixing pad assembly 2 to position a second type of washing machine drum component.

[0042] It should be noted that, due to the different motors mounted on the drum components, their component structures also differ. They can be categorized according to motor and machine type into DD motor series drum components, brushless DC motor series drum components, and pulsator drum components. Preferably, the first type of washing machine drum component is a brushless DC motor series drum component, and the second type is a DD motor series drum component.

[0043] The advantage of this design is that the positioning device 100 of this utility model includes an adjusting pad assembly 3, which is detachably mounted on the fixed pad assembly 2. By directly adding the adjusting pad assembly 3 to the fixed pad assembly 2, quick switching can be achieved to adapt to the positioning of the drum components of different washing machine models, thereby improving production efficiency and reducing costs.

[0044] In some embodiments of this utility model, the fixing pad assembly 2 includes a plurality of fixing pads, which are spaced apart on the support plate 1 and together form a positioning space adapted to the bottom of the first washing machine drum component.

[0045] The advantage of this design is that the fixed pad assembly 2, which consists of multiple fixed pads spaced apart, can provide more even support to the washing machine drum component 200, avoid excessive local stress, and also facilitate the adjustment and replacement of the fixed pads, resulting in high flexibility and low maintenance costs.

[0046] It should be noted that the number, position, and distribution of the fixing blocks can be set according to actual needs. In practical applications, a universal fixing block assembly 2 can be designed according to the structure, size, and positioning requirements of the drum components of various washing machine models. This ensures that the fixing block assembly 2 can stably support the drum component of one type of washing machine, and that it, together with the adjusting block assembly 3, can stably support the drum components of other types of washing machines.

[0047] In some embodiments of this utility model, the adjusting pad assembly 3 includes a plurality of adjusting pads, which are detachably mounted on the fixed pads. The plurality of adjusting pads and the plurality of fixed pads together form a positioning space adapted to the bottom of the second type of washing machine drum component.

[0048] The advantage of this design is that the adjusting pad assembly 3 consists of multiple detachable adjusting pads set on the fixed pad. The adjusting pad assembly 3 can be stacked on the original support plate 1 with the fixed pad assembly 2. This design allows for the addition of positioning function by stacking without changing the original structure, enabling quick switching to adapt to the positioning of the drum components of different washing machine models and reducing the time required for model switching.

[0049] It should be noted that the number, position, and distribution of the adjusting pads can be set according to actual needs. In practical applications, a universal adjusting pad assembly 3 can be designed based on the structure, size, and positioning requirements of the drum components of various washing machine models to ensure that it can stably support the drum components of different washing machine models when used in conjunction with the fixing pad assembly 2.

[0050] In a preferred embodiment of this utility model, the number of fixed pads is set to five, and the number of adjusting pads is set to three. The three adjusting pads are stacked on the three fixed pads by bolts and nuts.

[0051] The advantage of this design is that the adjusting pads are stacked on the fixed pads using bolts and nuts. This fixing method is simple and effective, allowing the adjusting pads to be quickly fixed in the appropriate position. At the same time, the use of bolts and nuts reduces the reliance on professional tools, making the installation and removal of the adjusting pads more convenient.

[0052] It should be noted that the relationship between the number of adjusting shims and the number of fixed shims can be set according to actual needs. Typically, the number of adjusting shims is set to be less than the number of fixed shims, which facilitates quick switching and reduces machine changeover time.

[0053] In some embodiments of this utility model, the adjusting pad and the fixing pad are any one of rectangular blocks, L-shaped blocks and irregular blocks.

[0054] The advantage of this design is that the shapes of the adjusting and fixing pads are more flexible, adapting to different shapes and sizes of washing machine drum components 200, thus enhancing convenience, stability, and adaptability. For example, rectangular blocks have a simple structure, making them easy to manufacture and install; L-shaped blocks offer good structural stability, better locking and supporting the washing machine drum component 200; and irregularly shaped blocks have good structural adaptability, allowing for better tight contact with the bottom of the washing machine drum component 200, enhancing stability.

[0055] In some embodiments of this utility model, such as Figure 11 , Figure 12 As shown, the fixed pad is provided with anti-slip protrusions 42, and the adjusting pad is provided with anti-slip grooves 41 that are adapted to the anti-slip protrusions 42.

[0056] The advantage of this design is that by setting anti-slip protrusions 42 on the fixed pad and anti-slip grooves 41 on the adjusting pad, the anti-slip protrusions 42 and anti-slip grooves 41 cooperate to form an anti-slip positioning structure, which not only facilitates quick positioning when assembling the adjusting pad and the fixed pad, but also prevents the adjusting pad from slipping laterally on the fixed pad, thus improving the stability of the adjusting pad during use.

[0057] In some embodiments of this utility model, the adjusting pad and the fixing pad are made of nylon, PVC or aluminum alloy.

[0058] The advantage of this design is that it allows for more flexible selection of materials for the adjusting and fixing pads, accommodating washing machine drum components 200 of different weights and sizes, thus enhancing adaptability. For example, nylon pads are suitable for supporting lighter and smaller washing machine drum components 200, and are less expensive; while PVC and aluminum alloy pads are suitable for supporting heavier and larger washing machine drum components 200, and are more expensive.

[0059] In some embodiments of this utility model, such as Figure 9 As shown, the adjusting pad is provided with a clearance groove 43.

[0060] The advantage of this design is that by setting the avoidance groove 43 on the adjusting pad, it can not only play a fixing role, but also avoid interference with the bottom of the washing machine drum component 200.

[0061] It should be noted that, according to the structure, size and positioning requirements of the washing machine drum component 200, clearance grooves 43 can be set at appropriate positions on some of the adjustment pads. The clearance grooves 43 can also be provided with supporting arc surfaces, so that the positioning device 100 can more stably support the washing machine drum component 200.

[0062] In some embodiments of this utility model, such as Figure 8 , Figure 9 As shown, the adjusting pad is provided with a positioning protrusion 44.

[0063] The advantage of this design is that by setting positioning protrusions 44 on the adjusting pad, the washing machine drum component 200 can be limited and fixed, ensuring that the washing machine drum component 200 is placed in an accurate position, and at the same time, it is convenient for the washing machine drum component 200 to be quickly positioned on the positioning device 100.

[0064] In some embodiments of this utility model, a support step 45 is provided on the positioning protrusion 44.

[0065] The advantage of this design is that by setting a support step 45 on the positioning protrusion 44, it can not only provide support, but also avoid interference with the bottom of the washing machine drum component 200.

[0066] To better understand, the positioning device 100 will now be described in detail using a preferred embodiment of the present invention as an example.

[0067] In this preferred embodiment, the positioning device 100 can satisfy the positioning of roller components of DD motor series, the positioning of roller components of brushless DC motor series, and may also satisfy the positioning of roller components of other models.

[0068] like Figures 4 to 7 As shown, this positioning device 100 includes a support plate 1, a fixing pad assembly 2 consisting of five fixing pads, and an adjusting pad assembly 3 consisting of three adjusting pads. For ease of explanation, the five fixing pads will now be referred to as the first fixing pad 21, the second fixing pad 22, the third fixing pad 23, the fourth fixing pad 24, and the fifth fixing pad 25, respectively, and the three adjusting pads will be referred to as the first adjusting pad 31, the second adjusting pad 32, and the third adjusting pad 33, respectively.

[0069] like Figure 4 , Figure 5 As shown, five fixing blocks are spaced apart on the support plate 1. These five fixing blocks can be fixed to the support plate 1 by welding or snap-fitting. Furthermore, the five fixing blocks have different shapes: the first fixing block 21 and the fifth fixing block 25 are irregularly shaped blocks, the second fixing block 22 is a rectangular block, and the second fixing block 22 and the third fixing block 23 are L-shaped blocks. These five fixing blocks of different shapes together form a positioning space that adapts to the bottom of the brushless DC motor series roller component. In addition, to facilitate the assembly between the fixing blocks and the adjusting blocks, the first fixing block 21, the fourth fixing block 24, and the fifth fixing block 25 each have three connecting holes, while the second fixing block 22 and the third fixing block 23 each have two connecting holes. Multiple through holes, corresponding to each connecting hole, can also be formed at corresponding positions on the support plate 1.

[0070] like Figures 6 to 10 As shown, the three adjusting pads have different shapes: the first adjusting pad 31 and the second adjusting pad 32 are irregularly shaped blocks, and the third adjusting pad 33 is a rectangular block. The first adjusting pad 31 and the third adjusting pad 33 each have three fixing holes, while the second adjusting pad 32 has two fixing holes. For example, each fixing hole of the first adjusting pad 31 corresponds to each connecting hole of the first fixing pad 21 for bolt insertion; each fixing hole of the second adjusting pad 32 corresponds to each connecting hole of the third fixing pad 23 for bolt insertion; and each fixing hole of the third adjusting pad 33 corresponds to each connecting hole of the fourth fixing pad 24 for bolt insertion. This allows the first adjusting pad 31 to be stacked on the first fixing pad 21 using bolts and nuts, the second adjusting pad 32 to be stacked on the third fixing pad 23 using bolts and nuts, and the third adjusting pad 33 to be stacked on the fourth fixing pad 24 using bolts and nuts. It should be understood that it is sufficient for the three adjusting pads to be assembled with three of the five fixed pads, rather than requiring a one-to-one correspondence between the adjusting pads and the fixed pads. The three adjusting pads and the five fixed pads together form a positioning space that is compatible with the bottom of the DD motor series roller component.

[0071] In addition, such as Figure 11 , Figure 12 As shown, the first adjusting pad 31 is provided with an anti-slip groove 41, and the first fixing pad 21 is provided with an anti-slip protrusion 42. The anti-slip protrusion 42 and the anti-slip groove 41 cooperate to form an anti-slip positioning structure. Figure 8 , Figure 9 As shown, the first adjusting pad 31 and the second adjusting pad 32 are provided with positioning protrusions 44. The positioning protrusions 44 of the first adjusting pad 31 are also provided with supporting steps 45, and the second adjusting pad 32 is also provided with clearance grooves 43 with supporting arc surfaces. These positioning protrusions 44, supporting steps 45 and clearance grooves 43 are all designed according to the structure, size and positioning requirements of the roller components of the DD motor series.

[0072] Understandably, after installing these three adjusting pads, the positioning device 100 can meet the positioning requirements of the drum components 200 of four washing machines in the DD motor series. After removing these three adjusting pads, the positioning device 100 can meet the positioning requirements of the drum components in the brushless DC motor series.

[0073] In this preferred embodiment, the positioning device 100 comprises three modules: a support plate 1, a fixing pad assembly 2, and an adjusting pad assembly 3. This modular design allows each adjusting pad to be fixed using bolts and nuts, enabling quick disassembly and replacement. By stacking adjusting pads, adjusting their positions, or replacing them with different specifications, the device can adapt to the needs of different washing machine models. A rapid switching mechanism is achieved in just 46 seconds to position the drum component 200 of the DD motor series washing machine. Furthermore, the stability and durability of the adjusting pads have been experimentally verified, ensuring their reliability during production. Currently, over 4000 washing machines have been produced using this positioning device 100. Moreover, integrating the adjusting pads into the production line, and testing their switching speed and production efficiency through actual operation, improves the flexibility of the production line, enabling rapid response to market demands for different models, reducing the complexity of manual operation, and minimizing production accidents caused by improper adjustments. This enhances the product's market competitiveness and meets diverse market demands.

[0074] The positioning device 100 provided by this utility model takes into account the needs of different models. By directly superimposing the adjusting pad assembly 3 on the original support plate 1 with the fixing pad assembly 2, it can quickly adapt to the positioning of the washing machine drum component 200 of different models. This flexibility enables the production line to respond quickly to market changes and meet the needs of different customers.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
