Description

Technical Field

[0001] This utility model relates to the field of fresh air conditioning production technology, and in particular to an auxiliary tooling and production system for the production of fresh air components. Background Technology

[0002] As people's demands for quality of life increase, fresh air ventilation air conditioners are becoming increasingly popular due to their efficient air purification and ability to effectively improve the indoor environment. In existing intelligent ventilation air conditioners, the ventilation structure of the fresh air component is complex. During production, the assembly of the ventilation fan requires fixing the motor and the volute housing with screws, making assembly efficiency a key constraint on production. In the assembly of the motor and volute housing of this fresh air component, after the motor is closed onto the volute housing, the screw holes are obscured, making direct observation impossible. This results in time-consuming and inaccurate manual alignment, severely impacting assembly efficiency. Furthermore, due to the lack of dedicated clamps to fix the volute housing and motor, during the screw fixing process, screws are prone to misalignment and accidentally hit the control board, potentially causing short circuits or equipment damage, posing a significant quality risk.

[0003] Therefore, it is necessary to improve the way the volute and the motor are fixed to each other in order to overcome the shortcomings of the existing technology. Summary of the Invention

[0004] To overcome the problems existing in the related technologies, one of the objectives of this utility model is to provide an auxiliary tooling for the production of fresh air components. This tooling can effectively position the fan and the volute, so that the screws of the fan and the volute can be accurately positioned and effectively fixed together, thereby improving the assembly efficiency of fresh air components.

[0005] An auxiliary tooling for the production of a fresh air component includes a base plate, on which an mounting position is provided, and a support structure is provided in the mounting position, the support structure being used to support and position a first workpiece;

[0006] The support structure is provided with a number of positioning components on its periphery. The positioning components are used to position the second workpiece, thereby fixing the second workpiece relative to the first workpiece.

[0007] During production, the fan is carefully placed on the support structure. The positioning groove at the bottom of the fan accurately engages with the positioning protrusion at the top of the support structure, achieving precise positioning and stable support for the fan. Then, the volute is effectively fixed using positioning components. Once the volute is fully positioned, the screw holes on the volute are perfectly aligned with the screw holes on the fan.

[0008] Because the support structure can accurately determine the position of the fan, it will not shift during assembly. The positioning components are set around the support structure to position the volute from multiple directions, ensuring the relative positional accuracy between the volute and the fan. This allows for precise positioning of the fan screws and the volute. Compared with traditional assembly methods, this greatly improves the accuracy of positioning and reduces assembly problems caused by positioning deviations, such as screws that cannot be tightened or unstable operation of components after assembly.

[0009] In traditional assembly, locating and aligning the screw holes of the fan and the volute is often time-consuming and prone to errors. This auxiliary tooling enables rapid positioning, allowing operators to quickly complete the positioning and assembly of the fan and volute. Furthermore, the multiple mounting positions and supporting components allow multiple people to perform assembly operations simultaneously, forming a streamlined process that further improves the overall assembly efficiency of the fresh air components. This allows for the production of more fresh air components per unit time, reducing production costs.

[0010] In a preferred embodiment of this utility model, the support structure includes a support member and a positioning boss. The support member is fixed on the base plate, and the positioning boss is detachably mounted on the support member. The first workpiece is provided with a positioning groove, and the positioning boss and the positioning groove are adapted to each other.

[0011] In this embodiment, the positioning boss matches the positioning groove on the first workpiece (ventilation fan), accurately determining the position of the ventilation fan on the assembly device. In traditional assembly processes, due to the irregular structure of the fresh air component, the screw holes are difficult to align after the motor cover is fitted with the volute. This support structure ensures the accuracy of the ventilation fan's position, making it easier to align the screw holes on the motor mainboard with the volute holes, improving assembly precision and significantly reducing quality problems caused by assembly errors. The positioning boss is detachably mounted on the support, allowing for quick replacement of the corresponding positioning boss according to the positioning groove of different ventilation fan models. When producing multiple models of fresh air ventilation air conditioners, companies no longer need to design a separate assembly device for each model, reducing production costs while improving production flexibility and efficiency, better meeting diverse market demands.

[0012] In a preferred embodiment of this invention, the support member is provided with a plurality of screw holes, and the positioning boss is provided with a connecting post, which is threadedly connected to the screw holes.

[0013] This embodiment provides a detachable connection method between the positioning boss and the support component. The positioning boss is threadedly connected to the screw hole on the support component via a connecting post. This connection method is simple to operate; the operator only needs to rotate the positioning boss to complete the installation, greatly saving installation time. Moreover, the threaded connection has good stability and reliability, ensuring that the positioning boss will not loosen or shift during assembly, providing a solid guarantee for the accurate positioning of the ventilation fan.

[0014] In a preferred embodiment of this utility model, the positioning component includes a first positioning structure, a second positioning structure, a third positioning structure, and a fourth positioning structure distributed circumferentially on the base plate along the support structure.

[0015] The various positioning structures form a limiting position for positioning the second workpiece.

[0016] In this embodiment, four positioning structures are distributed circumferentially along the support structure to form limiting positions, thereby positioning the second workpiece (volute) from multiple directions. This omnidirectional positioning method effectively avoids problems such as displacement or tilting of the volute during assembly, allowing for more precise alignment between the volute and the screw holes of the ventilation fan. This significantly improves assembly accuracy, reduces quality issues caused by assembly errors, and enhances the overall quality of the product. The various positioning structures work collaboratively in different positions, providing stable positioning support for the volute.

[0017] In a preferred embodiment of this invention, the sidewall of the first positioning structure is provided with a first positioning groove; the sidewall of the second positioning structure is provided with a second positioning groove, the cross-section of the second positioning groove being rectangular.

[0018] In a preferred embodiment of this invention, the third positioning structure includes two positioning plates arranged opposite to each other, both positioning plates being L-shaped, and a clamping position being formed between the two positioning plates.

[0019] In a preferred embodiment of this invention, the fourth positioning structure is provided with a fourth positioning groove, and the cross-section of the fourth positioning groove is V-shaped.

[0020] In a preferred embodiment of this invention, several mounting positions are provided on the base plate.

[0021] In practical applications, it has been suggested to set several mounting positions on the base plate, which can improve the assembly efficiency of the first and second workpieces. For example, setting two mounting positions with identical structures allows for the simultaneous placement of two sets of ventilation fans and volutes. One person can place the components while another screws them in, enabling a two-person assembly line operation that greatly improves assembly efficiency.

[0022] In a preferred embodiment of this invention, a foot pad is provided at the bottom of the base plate, and the foot pad is detachably connected to the base plate.

[0023] The foot pads support the base plate, preventing it from directly contacting the ground and providing anti-slip, shock absorption, and protection. Furthermore, the detachable design of the foot pads allows for replacement or adjustment as needed, increasing the base plate's flexibility and ease of maintenance.

[0024] The second objective of this utility model is to provide a fresh air component production system, including the auxiliary tooling for fresh air component production as described above.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model provides an auxiliary tooling for the production of fresh air components. The tooling includes a base plate with mounting positions. A support structure is located within the mounting positions, supporting and positioning a first workpiece. Several positioning components are arranged around the support structure to position a second workpiece, thus fixing the second workpiece relative to the first workpiece. In practical applications, a fan is used as the first workpiece, and a volute as the second workpiece, for assembly using this auxiliary tooling. First, the support structure effectively positions and supports the fan. Then, the positioning components effectively fix the volute. Once the volute is fully positioned, the screw holes on the volute are perfectly aligned with the screw holes on the fan. The operator then uses screws to secure the volute to the fan, completing the assembly of the fan and volute in the fresh air component. This tooling ensures the relative positional accuracy of the volute and fan, enabling precise positioning between the fan screws and the volute, greatly improving positioning accuracy, reducing assembly problems caused by positioning deviations, and helping to ensure production quality. Furthermore, because it enables rapid positioning of the fan and volute, operators can quickly complete the positioning and assembly of the fan and volute, which helps improve work efficiency.

[0027] This application also provides a production system that includes the aforementioned auxiliary tooling for producing fresh air components. This production system can effectively improve the assembly efficiency of fresh air components by utilizing the aforementioned auxiliary tooling, thereby reducing production costs.

[0037] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0038] As people's demands for quality of life increase, fresh air ventilation air conditioners are becoming increasingly popular due to their efficient air purification and ability to effectively improve the indoor environment. In existing intelligent ventilation air conditioners, the ventilation structure of the fresh air component is complex. During production, the assembly of the ventilation fan requires fixing the motor and the volute housing with screws, making assembly efficiency a key constraint on production. In the assembly of the motor and volute housing of this fresh air component, after the motor is closed onto the volute housing, the screw holes are obscured, making direct observation impossible. This results in time-consuming and inaccurate manual alignment, severely impacting assembly efficiency. Furthermore, due to the lack of dedicated clamps to fix the volute housing and motor, during the screw fixing process, screws are prone to misalignment and accidentally hit the control board, potentially causing short circuits or equipment damage, posing a significant quality risk.

[0039] Based on this, this application provides an auxiliary tooling for the production of fresh air components.

[0040] Example 1

[0041] like Figures 1-7 As shown, this embodiment provides an auxiliary tooling for the production of fresh air components, including a base plate 1, an installation position 11 provided on the base plate, and a support structure 2 provided in the installation position 11. The support structure 2 is used to support and position a first workpiece.

[0042] The support structure 2 is provided with a plurality of positioning components on its periphery. The positioning components are used to position the second workpiece, thereby fixing the second workpiece relative to the first workpiece.

[0043] Specifically, in practical applications, the mounting position 11 can be formed by combining the support structure 2 and the positioning components. The mounting position 11 is used for assembling the fresh air components. The base plate 1, the support structure 2, and the positioning components can all be made of metal materials, such as high-strength aluminum alloy. This high-strength structure ensures that neither the first nor the second workpiece will shake or shift during the assembly process.

[0044] During production, the fan 100 is placed on the support structure 2. The positioning groove at the bottom of the fan 100 accurately engages with the positioning protrusion at the top of the support structure 2, achieving precise positioning and stable support of the fan on the support structure 2. Then, the volute 200 is effectively fixed using the positioning assembly. Once the volute 200 is fully positioned, the screw holes on the volute 200 are perfectly aligned with the screw holes on the fan.

[0045] Because the support structure 2 can accurately determine the position of the fan, it will not shift during assembly. The positioning components are set around the support structure 2 and position the volute 200 from multiple directions, ensuring the relative positional accuracy between the volute and the fan. This allows the fan screws to be precisely positioned with the volute. Compared with traditional assembly methods, this greatly improves the accuracy of positioning and reduces assembly problems caused by positioning deviations, such as screws not being able to be tightened or unstable operation of components after assembly.

[0046] In traditional assembly, locating and aligning the screw holes of the fan 100 and the volute 200 often takes a lot of time and is prone to errors. This auxiliary tooling enables rapid positioning, allowing operators to quickly complete the positioning and assembly of the fan and volute. Furthermore, the multiple mounting positions 11 and supporting components allow multiple people to perform assembly operations simultaneously, forming a streamlined process that further improves the overall assembly efficiency of the fresh air components. This allows for the production of more fresh air components per unit time, reducing production costs.

[0047] Example 2

[0048] This embodiment is an improvement on embodiment 1.

[0049] like Figures 1-7 As shown, in this embodiment, the support structure 2 includes a support member 21 and a positioning boss 22. The support member 21 is fixed on the base plate 1, and the positioning boss 22 is detachably mounted on the support member 21. The first workpiece is provided with a positioning groove, and the positioning boss 22 is adapted to the positioning groove.

[0050] In this embodiment, the positioning boss 22 is adapted to the positioning groove on the first workpiece (ventilation fan), enabling precise determination of the ventilation fan's position on the assembly device. In traditional assembly processes, due to the irregular structure of the fresh air component, the screw holes are difficult to align after the motor cover is fitted with the volute. This support structure 2 ensures the accuracy of the ventilation fan's position, making it easier to align the motor mainboard screw holes with the volute holes, improving assembly precision and significantly reducing quality problems caused by assembly errors. The positioning boss 22 is detachably mounted on the support member 21. This design allows for quick replacement of the corresponding positioning boss 22 according to the positioning grooves of different ventilation fan models. When producing multiple models of fresh air ventilation air conditioners, enterprises no longer need to design a separate assembly device for each model, reducing production costs while improving production flexibility and efficiency, better meeting diverse market demands.

[0051] During assembly, taking a specific model of ventilation fan as an example, its outer casing has positioning grooves of a specific shape and size. A positioning boss 22, adapted to the positioning groove of this model of ventilation fan, is installed onto the support 21. The ventilation fan is then placed on the support 21, where the positioning boss 22 fits precisely into the positioning groove, achieving accurate positioning. After positioning, the volute is placed above the ventilation fan. Following the original assembly procedure, the motor wires are passed through the holes in the volute, aligning the motor mainboard screw holes with the three holes in the volute. The operator can then tighten the screws, securing the volute to the ventilation fan. When assembling different models of ventilation fans, simply remove the current positioning boss 22 and replace it with a positioning boss 22 adapted to the positioning groove of the new model. The assembly process can then be repeated, achieving effective positioning and assembly of different models of ventilation fans.

[0052] Example 3

[0053] This embodiment is an improvement on embodiment 2.

[0054] like Figures 1-7 As shown, in this embodiment, the support member 21 is provided with a plurality of screw holes 211, and the positioning boss 22 is provided with a connecting post 221, which is threadedly connected to the screw holes 211.

[0055] This embodiment provides a detachable connection between the positioning boss 22 and the support member 21. The positioning boss 22 is threadedly connected to the screw hole 211 on the support member 21 via a connecting post 221. This connection method is simple to operate; the operator only needs to rotate the positioning boss 22 to complete the installation, greatly saving installation time. Moreover, the threaded connection has good stability and reliability, ensuring that the positioning boss 22 will not loosen or shift during assembly, providing a solid guarantee for the accurate positioning of the ventilation fan.

[0056] Furthermore, the support member 21 is provided with several screw holes 211, which allows for the installation of positioning bosses 22 of different specifications in practical applications. This design enables the assembly device to be compatible with various models of ventilation fans. When producing fresh air ventilation air conditioners of various specifications, enterprises do not need to frequently replace the entire assembly device; they only need to replace the positioning bosses 22 to meet the assembly requirements of different models of ventilation fans, greatly reducing production costs and improving production efficiency and equipment versatility.

[0057] In addition, the position of the positioning boss 22 can also be flexibly adjusted as needed.

[0058] Example 4

[0059] This embodiment is an improvement on embodiment 1.

[0060] like Figures 1-7 As shown, in this embodiment, the positioning component includes a first positioning structure 3, a second positioning structure 4, a third positioning structure 5, and a fourth positioning structure 6 distributed circumferentially on the base plate 1 along the support structure 2.

[0061] The various positioning structures form a limiting position for positioning the second workpiece.

[0062] In this embodiment, four positioning structures are distributed circumferentially along the support structure to form limiting positions, thereby positioning the second workpiece (volute) from multiple directions. This omnidirectional positioning method effectively avoids problems such as displacement or tilting of the volute during assembly, allowing for more precise alignment between the volute and the screw holes of the ventilation fan. This significantly improves assembly accuracy, reduces quality issues caused by assembly errors, and enhances the overall quality of the product. The various positioning structures work collaboratively in different positions, providing stable positioning support for the volute.

[0063] The first positioning structure 3, the second positioning structure 4, the third positioning structure 5, and the fourth positioning structure 6 are distributed along the circumference of the support structure 2. For example, if the support structure 2 is located at the center of the base plate 1, the first positioning structure 3 can be a metal block with a groove of a specific shape, located on the left side of the support structure 2; the second positioning structure 4 can be a height-adjustable positioning post located on the right side of the support structure 2; the third positioning structure 5 is a rubber positioning block with elastic cushioning function, located in front of the support structure 2; and the fourth positioning structure 6 is a magnetic positioning piece, installed behind the support structure 2.

[0064] In practical applications, the shapes of the four positioning structures can be adjusted as needed. More preferably, all four positioning structures are detachably mounted on the base plate 1 for easy replacement.

[0065] Example 5

[0066] This embodiment is an improvement on embodiment 1.

[0067] like Figures 1-7 As shown, in this embodiment, the detailed structures of the four positioning structures are provided. Specifically:

[0068] The first positioning structure 3 has a first positioning groove 31 on its side wall; the second positioning structure 4 has a second positioning groove 41 on its side wall, and the cross-section of the second positioning groove 41 is rectangular.

[0069] More preferably, in this embodiment, the third positioning structure 5 includes two positioning plates arranged opposite each other, both positioning plates being L-shaped, and a clamping position 51 being formed between the two positioning plates.

[0070] In this embodiment, the fourth positioning structure 6 is provided with a fourth positioning groove 61, and the cross-section of the fourth positioning groove 61 is V-shaped.

[0071] This embodiment provides a positioning structure that matches a specific fresh air structure. The specific installation process is as follows:

[0072] During assembly, the worker places the volute to be assembled into the designated area of ​​the tooling. First, one edge of the volute is aligned with the first positioning groove 31 of the first positioning structure 3. The size of the first positioning groove 31 matches the edge of the volute. After the edge of the volute is embedded in the groove, it can initially limit the volute in the horizontal direction, ensuring that the volute will not deviate significantly in this direction.

[0073] Next, the worker moves the volute closer to the second positioning structure 4. The second positioning groove 41, with its rectangular cross-section, then connects with the protrusion on the other edge of the volute. Due to the right-angle characteristic of the rectangular groove, the volute can be precisely positioned simultaneously in both the horizontal and vertical directions, further limiting its range of motion and making its position more accurate.

[0074] Then, the worker adjusts the volute to the third positioning structure 5. The clamping position 51 between the two L-shaped positioning plates of the third positioning structure 5 can just accommodate a specific part of the volute. The worker places the corresponding part of the volute into the clamping position 51, and the vertical and horizontal edges of the L-shaped positioning plates clamp and position the volute from two directions, providing additional stable support and preventing the volute from shaking or shifting during assembly.

[0075] Finally, the volute is fitted with the fourth positioning structure 6. The V-shaped fourth positioning groove 61 on the fourth positioning structure 6 is used to position the curved edge of the volute. When the curved edge of the volute contacts the V-shaped groove, the special shape of the V-shaped groove can automatically center it. No matter how slight the position of the curved edge of the volute is deviated, it will automatically adjust to the appropriate position under the action of the V-shaped groove, thereby achieving precise positioning at the curved edge.

[0076] In this embodiment, through the coordinated work of these four positioning structures, the volute can be precisely positioned on the tooling and accurately aligned with the first workpiece (such as a ventilation fan) that has been positioned below by the support structure 2, which facilitates subsequent assembly operations such as motor wiring and screw fixing.

[0077] In actual operation, when staff use the four positioning structures to position the volute, they do not have to follow a specific order.

[0078] Example 6

[0079] This embodiment is an improvement on embodiment 1.

[0080] like Figures 1-7 As shown, in this embodiment, several mounting positions 11 are provided on the base plate 1.

[0081] In practical applications, it has been found that setting several mounting positions 11 on the base plate 1 can improve the assembly efficiency of the first workpiece and the second workpiece. For example, setting two mounting positions 11 with the same structure can simultaneously place two sets of ventilation fans and volutes, allowing one person to place them while another person screws them in, enabling a two-person assembly line operation that greatly improves assembly efficiency.

[0082] Alternatively: The base plate 1 has three mounting positions 11. In actual production, three workers work together. One worker is responsible for placing the three sets of ventilation fans onto the support structures 2 of the three mounting positions 11, using the support structures 2 to support and position the ventilation fans. The other two workers are responsible for placing the volute housing onto the positioning components for positioning, and then completing the subsequent wiring and screw fixing of the motor. Because the three mounting positions 11 are structurally identical and independent, the three workers can operate simultaneously, forming a highly efficient assembly line operation.

[0083] The multiple installation positions 11 allow the tooling to assemble multiple sets of fresh air components simultaneously. This multi-person assembly line operation mode makes full use of human resources and reduces waiting time. Compared to a tooling with a single installation position 11, more products can be assembled in the same amount of time, greatly improving production efficiency and meeting the company's growing production needs.

[0084] Example 7

[0085] This embodiment is an improvement on embodiment 1.

[0086] like Figures 1-7 As shown, in this embodiment, a foot pad 12 is provided at the bottom of the base plate 1, and the foot pad 12 is detachably connected to the base plate 1.

[0087] The foot pads 12 are used to support the base plate 1, preventing the base plate 1 from directly contacting the ground, and serving to prevent slipping, absorb shock, and protect the base plate 1. Furthermore, the detachable design of the foot pads 12 allows them to be replaced or adjusted as needed, increasing the flexibility and ease of maintenance of the base plate 1.

[0088] Specifically, four foot pads 12 are evenly distributed on the bottom of the base plate 1. These foot pads 12 are made of nitrile rubber, which has good anti-slip and shock-absorbing properties. Each foot pad 12 has a threaded post on its top that matches the screw hole 211 on the bottom of the base plate 1, and is detachably connected to the base plate 1 by means of a threaded connection. In daily production, workers place the tooling on the assembly workbench in the workshop. The nitrile rubber foot pads 12 are in close contact with the surface of the workbench, and the textured design of their surface increases the friction between them and the workbench, effectively preventing the tooling from slipping due to vibration or worker operation during assembly, ensuring the stability of the tooling. During the assembly process, operations such as fixing the motor and the volute will generate a certain amount of vibration. The foot pads 12 can absorb this vibration energy, reducing the impact of vibration on the internal structure of the tooling and the fresh air components being assembled, avoiding assembly errors caused by vibration, and ensuring assembly accuracy.

[0089] Example 8

[0090] This embodiment provides a fresh air component production system, including the auxiliary tooling for fresh air component production as described above.

[0091] In addition to the auxiliary tooling used for producing the fresh air components mentioned above, the production system also includes conveyor belts and testing equipment. After assembly, the assembled fresh air components are transported to the next testing stage via an automated conveyor belt. The testing equipment comprehensively tests the performance of the fresh air components to ensure product quality meets standards. If any problems are found during the testing process, they are promptly reported to the assembly stage. Workers can then check and adjust parameters such as the positioning accuracy of the auxiliary tooling based on the feedback information to ensure the assembly quality of subsequent products.

[0092] This system significantly improves the assembly speed of fresh air components by utilizing efficient positioning and a multi-installation-position design in the auxiliary tooling used for production, combined with a multi-person assembly line operation mode. Compared with traditional assembly methods, it can complete the assembly of more products per unit time, effectively shortening the production cycle, meeting the growing market demand for fresh air components, and improving the company's production efficiency.

[0093] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0094] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0095] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
