Description

Technical Field

[0001] This application relates to the field of motor assembly technology, and in particular to a stator assembly housing device. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It typically includes a stator, rotor, shaft, bearings, radiator, and housing. The motor housing protects the internal components and provides mechanical support and insulation. The housing is usually made of metal or plastic and has a certain structural strength and protective performance.

[0003] During the assembly of the motor, the stator needs to be pressed into the housing. Before pressing, the housing needs to be heated to expand so that the stator can be easily pressed into the housing. However, the existing technology has technical problems such as low automation and high labor costs. Summary of the Invention

[0004] To improve the assembly efficiency of stator assembly and housing, this application provides a stator assembly housing insertion device.

[0005] The stator assembly housing insertion device provided in this application adopts the following technical solution:

[0006] A stator assembly housing insertion device includes a fixed frame, a positioning plate for placing the housing, an upper conveying mechanism for driving the positioning plate to be horizontally conveyed, and lifting conveying mechanisms disposed at both ends of the upper conveying mechanism. The fixed frame is provided with a high-frequency heating mechanism for heating the housing, an assembly mechanism for stator installation, and a heat dissipation and ventilation mechanism for cooling the assembled motor at intervals along the conveying direction of the upper conveying mechanism. The positioning plate has positioning holes for positioning and insertion of the housing.

[0007] By adopting the above technical solution, the positioning plate is used to place the housing, and the upper conveying mechanism drives the positioning plate to be conveyed horizontally. The housing heating, stator assembly and heat dissipation processes are carried out along the conveying direction. The lifting conveying mechanism is set at both ends of the upper conveying mechanism for loading and unloading the positioning plate. The positioning plate is opened with positioning holes, which improves the automation of stator assembly entering the housing and reduces labor costs.

[0008] Optionally, the upper conveying mechanism includes a first conveying component, a lifting component that is lifted and installed on the fixed frame for lifting the positioning plate, and a blocking component that is lifted and installed on the fixed frame for restricting the conveying of the positioning plate. The lifting component corresponds one-to-one with the high-frequency heating mechanism and the assembly mechanism, and the blocking component corresponds one-to-one with the high-frequency heating mechanism, the assembly mechanism, and the heat dissipation and ventilation mechanism.

[0009] By adopting the above technical solution, the first conveying component of the upper conveying mechanism realizes the horizontal conveying of the positioning plate. The lifting component can lift the positioning plate, which facilitates the corresponding operations at the high-frequency heating mechanism and the assembly mechanism. The baffle component can restrict the conveying of the positioning plate to ensure accurate positioning at the high-frequency heating mechanism, the assembly mechanism and the heat dissipation and ventilation mechanism. This improves the automation level of the stator assembly housing device and reduces labor costs.

[0010] Optionally, the lifting assembly includes a lifting bracket for mounting on the fixed frame, a lifting drive component disposed on the lifting bracket, and a lifting plate disposed on the output shaft of the lifting drive component. The lifting plate is provided with a plurality of lifting support rods, and the bottom of the positioning plate is provided with lifting insertion holes for the lifting support rods to be inserted one by one.

[0011] By adopting the above technical solution, the lifting assembly is installed on the fixed frame using the lifting bracket. The lifting drive component drives the lifting plate and lifting support rod to rise. The lifting support rod is inserted into the lifting insertion hole at the bottom of the positioning plate to realize the lifting of the positioning plate. This facilitates the precise position adjustment of the machine housing between different workstations, improves the automation level of the stator assembly housing insertion device, and reduces labor costs.

[0012] Optionally, the material blocking assembly includes a material blocking bracket, a material blocking drive component disposed on the material blocking bracket, and a material blocking positioning rod disposed on the output shaft of the material blocking drive component. The positioning plate has a positioning slot for the material blocking positioning rod on its side wall facing the conveying direction.

[0013] By adopting the above technical solution, the positioning rod is driven by the material blocking drive component to insert into the positioning slot of the positioning plate, which can restrict the conveying of the positioning plate, ensure that the positioning plate stops accurately at each station, and improve the working accuracy and stability of the stator assembly housing device.

[0014] Optionally, the lifting assembly corresponding to the assembly mechanism is further provided with a rotor positioning assembly. The rotor positioning assembly includes a rotor positioning plate disposed on the lifting plate, a rotor positioning drive component disposed on the rotor positioning plate, and a rotation positioning component disposed on the rotor positioning drive component and used to clamp the rotor assembly. The lifting plate is provided with a guide sleeve that fits and cooperates with the rotation positioning component.

[0015] By adopting the above technical solution, a lifting component corresponding to the assembly mechanism is set in the stator assembly housing device, and a rotor positioning component is set on the lifting component. The rotor assembly can be clamped and positioned by using the rotor positioning plate, rotor positioning drive component and rotating positioning component. The guide sleeve set on the lifting plate and the rotating positioning component are fitted together to play a guiding role, which improves the accuracy of rotor positioning during stator installation, realizes more precise stator and housing assembly, helps to improve assembly efficiency and quality, reduce manual intervention and improve the degree of automation.

[0016] Optionally, the upper conveying mechanism is further provided with a height limiting plate corresponding to the assembly mechanism and used to press the positioning plate.

[0017] By adopting the above technical solution, the height limiting plate presses against the positioning plate during the stator installation process, further improving the stability of the stator assembly housing device when assembling the stator.

[0018] Optionally, the fixed frame is further provided with a lower conveying mechanism for recycling the positioning plate. The lower conveying mechanism and the upper conveying mechanism are arranged in parallel, and the conveying direction of the lower conveying mechanism is opposite to that of the upper conveying mechanism. The lower conveying mechanism is also provided with the material blocking component for restricting the conveying of the positioning plate.

[0019] By adopting the above technical solution, a recyclable positioning plate is set in the lower conveying mechanism, which enables the positioning plate to be reused and reduces costs. The lower conveying mechanism is parallel to the upper conveying mechanism and the conveying direction is opposite, which makes reasonable use of space and makes the layout of the device more compact. A baffle component is set in the lower conveying mechanism, which can accurately control the conveying of the positioning plate and improve the automation level of the entire device.

[0020] Optionally, the lifting and conveying mechanism includes a lifting drive component disposed on the fixed frame, a lifting guide component disposed on the output end of the lifting drive component, and a horizontal conveying component installed on the lifting guide component. The lifting drive component enables the horizontal conveying component to have a first height and a second height. When the horizontal conveying component is at the first height, the horizontal conveying component corresponds to the upper conveying mechanism. When the horizontal conveying component is at the second height, the horizontal conveying component corresponds to the lower conveying mechanism.

[0021] By adopting the above technical solution, the installation of the fixed frame, positioning plate, upper conveying mechanism, lifting conveying mechanism, high-frequency heating mechanism, assembly mechanism, heat dissipation and ventilation mechanism, and positioning sockets enables automated operation of stator assembly installation, improving the degree of automation and reducing labor costs. The lifting drive of the lifting conveying mechanism enables the horizontal conveyor to have a first height and a second height. At the first height, it corresponds to the upper conveying mechanism, and at the second height, it corresponds to the lower conveying mechanism, realizing the conveying conversion of the positioning plate between the upper and lower conveying mechanisms, improving the conveying efficiency and continuity of the equipment.

[0022] Optionally, the high-frequency heating mechanism includes a high-frequency heating bracket, a heating lifting component disposed on the high-frequency heating bracket, a heating coil that is lifted and installed on the heating lifting component, and a rotor sleeve for insertion into the rotor assembly.

[0023] The assembly mechanism includes an assembly bracket, an assembly lifting component disposed on the assembly bracket, a stator mounting bracket disposed on the assembly lifting component and used for stator placement, and a stator pushing component disposed on the assembly lifting component and used for pushing the stator.

[0024] By adopting the above technical solution, the heating coil of the high-frequency heating mechanism can heat the casing, causing the casing to expand and facilitating the stator pressing in; the rotor sheath inserted into the rotor can provide protection; the stator mounting bracket of the assembly mechanism can place the stator, and the stator pusher can push the stator to complete the stator installation.

[0025] Optionally, the stator mounting bracket includes a stator placement plate, a stator base disposed on the stator placement plate, and a stator clamping member for clamping the stator. The stator base has a through hole penetrating both end faces for feeding. The stator clamping member includes a first clamping plate, a second clamping plate, and a clamping drive member for driving the two clamping plates to move closer or further apart from each other. Both the first clamping plate and the second clamping plate are provided with clamping side plates. The stator base has clamping clearance holes for the clamping side plates to pass through.

[0026] By adopting the above technical solution, a stator placement plate is set to facilitate the placement of the stator, and a material feeding through hole is opened on the stator base to facilitate the downward entry of the stator into the machine housing. The stator clamping component can clamp the stator by driving the first clamping plate and the second clamping plate to move closer or further away through the clamping drive component. The clamping side plates of the first clamping plate and the second clamping plate pass through the clamping clearance hole of the stator base to achieve stable and reliable clamping of the stator, improve the stability and accuracy of the stator during the assembly process, facilitate the accurate installation of the stator into the machine housing, improve the assembly accuracy and efficiency of the stator assembly housing device, and reduce labor costs.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] With the cooperation of the upper conveying mechanism and the lifting conveying mechanism, the housing can be automatically conveyed. Combined with the high-frequency heating mechanism, the assembly mechanism and the heat dissipation and ventilation mechanism, the automation level of the stator assembly entering the housing is improved.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0045] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.

[0046] This application discloses a stator assembly housing device.

[0047] Reference Figure 1 The stator assembly housing installation device includes a fixed frame 1, a positioning plate 2, an upper conveying mechanism 3, a lifting conveying mechanism 4, and a lower conveying mechanism 5. A high-frequency heating mechanism 6 for heating the housing 91, an assembly mechanism 7 for installing the stator assembly 93, and a heat dissipation and ventilation mechanism 8 for cooling the housing 91 are sequentially arranged on the top of the fixed frame 1 along the conveying direction of the station conveying mechanism. The motor assembly 9 includes a housing 91, a rotor assembly 92, and a stator assembly 93. Before assembling the stator assembly 93 and the housing 91, the housing 91 is first assembled with the rotor assembly 92. In this application, the bottom of the housing 91 has three sets of support legs.

[0048] Reference Figure 2 and Figure 3 The positioning plate 2 is a rectangular plate with a shaft through hole 21 at its geometric center, which passes through both end faces and allows the shaft of the rotor assembly 92 to pass through. The positioning plate 2 has positioning holes 22 spaced circumferentially on the outer side of the shaft through hole 21 for the support legs of the housing 91 to be inserted.

[0049] Reference Figure 4 The upper conveying mechanism 3 is located on the top surface of the fixed frame 1 and is used for horizontally conveying the positioning plate 2 with the housing 91. The upper conveying mechanism 3 includes a first conveying assembly 31, a lifting assembly 32, and a baffle assembly 33. The first conveying assembly 31 includes two sets of parallel belt conveying mechanisms. The top of the belt conveying mechanism is also fixedly installed with a limit guide plate 311. The gap between the two sets of limit guide plates 311 is adapted to the width of the positioning plate 2 to ensure the stability of the positioning plate 2 during conveying.

[0050] Combination Figure 5 and Figure 6 The upper conveying mechanism 3 is equipped with two sets of lifting components 32 along the conveying direction. The two sets of lifting components 32 correspond to the high-frequency heating mechanism 6 and the assembly mechanism 7, respectively. The lifting components 32 are used to lift the lifting plate 323 upward so that the lifting plate 323 is disengaged from the belt of the upper station conveying component. Therefore, the upper conveying mechanism 3 is equipped with sensors corresponding to the two sets of mechanisms. The two sets of lifting components 32 are defined as the first lifting component and the second lifting component. The first lifting component includes a lifting bracket 321 fixed to the fixed frame 1, a lifting drive component 322 disposed on the lifting bracket 321, and a lifting plate 323 installed on the output shaft of the lifting drive component 322.

[0051] The lifting bracket 321 is L-shaped and is fixed to the fixed frame 1 by bolts. The lifting drive component 322 is a vertically arranged telescopic cylinder. The lifting plate 323 has the same overall area as the positioning plate 2. The top of the lifting plate 323 has four sets of lifting support rods 3231. The lifting plate 323 has a lifting side plate 3232 fixed to the output shaft of the lifting drive component 322. The lifting side plate 3232 is an L-shaped plate.

[0052] The lifting rods 3231 are located at the four corners of the lifting plate 323. The bottom of the positioning plate 2 is provided with lifting insertion holes 23 for the lifting rods 3231 to be inserted one by one. The top of the lifting rods 3231 also has a guide arc surface 3233 to improve the insertion efficiency of the lifting rods 3231 and the lifting plate 323.

[0053] The second lifting assembly has the same overall structure as the first lifting assembly, except that the second lifting assembly also has a rotor positioning assembly 34 for clamping and fixing the rotating shaft. The rotor positioning assembly 34 includes a rotor positioning plate 341, a rotor positioning drive component 342, and a rotation positioning component 343.

[0054] The rotor positioning plate 341 and the lifting side plate 3232 are fixedly connected. The rotor positioning drive component 342 is a telescopic cylinder fixed to the top of the rotor positioning plate 341. The rotating positioning component 343 includes a connecting part 3431 fixed to the output shaft of the rotor positioning drive component 342 and a clamping part 3432 sleeved on and clamping the rotating shaft.

[0055] The lifting plate 323 of the second lifting assembly has a lifting through hole 3234 that extends through both end faces and provides space for the clamping part 3432. A guide sleeve 3235 is also fixedly installed on the lifting plate 323 and sleeved on the outside of the clamping part 3432. The guide sleeve 3235 and the lifting through hole 3234 are arranged coaxially.

[0056] The clamping part 3432 includes six sets of clamping plates, with deformation gaps between adjacent clamping plates. The cross-sections of the six sets of clamping plates gradually extend outward from bottom to top, and the inner wall of the guide sleeve 3235 has clamping arc grooves 3236 that are adapted to the clamping plates. In the initial state, the clamping plates are located at the top opening protruding from the guide sleeve 3235. When the rotor shaft of the rotor assembly 92 is inserted into the clamping part 3432, the rotor positioning drive 342 is activated, driving the rotating positioning member 343 to move downward as a whole. The cooperation between the clamping plates and the clamping arc grooves 3236 causes the two sets of clamping plates to gradually retract inward, thereby locking the rotor shaft and improving the stability of the stator assembly 93 during installation.

[0057] The first conveying component 31 is also provided with a height limiting plate 312 corresponding to the assembly mechanism 7. The height limiting plate 312 can limit the rise of the positioning plate 2 and limit the top of the positioning plate 2 to abut, thereby further improving the assembly stability of the stator component 93.

[0058] Reference Figure 4 and Figure 7 The upper conveying mechanism 3 is equipped with three sets of baffle components 33 along the conveying direction. The three sets of baffle components 33 correspond one-to-one with the high-frequency heating mechanism 6, the assembly mechanism 7, and the heat dissipation and ventilation mechanism 8. The baffle components 33 are used to block the positioning plate 2 so that the housing 91 on the positioning plate 2 can be assembled in the corresponding mechanism.

[0059] The material blocking assembly 33 includes a material blocking bracket 331 bolted to the fixed frame 1, a material blocking drive component 332 disposed on the material blocking bracket 331, and a material blocking positioning rod 333 disposed on the output shaft of the material blocking drive component 332. The material blocking drive component 332 is a vertically fixed telescopic cylinder, and the material blocking positioning rod 333 is generally T-shaped, with material blocking inserts 3331 integrally disposed at both ends of its top. The side wall of the positioning plate 2 has positioning slots 24 that engage with the material blocking inserts 3331.

[0060] The output shaft of the material stop drive 332 is in the extended state under normal conditions, so that the positioning plate 2 can be positioned by the cooperation of the positioning slot 24 and the material stop positioning rod 333. After the housing 91 on the positioning plate 2 is assembled, the material stop drive 332 is reset, so that the material stop positioning rod 333 moves down and the limit block is released.

[0061] Reference Figure 8 The lifting and conveying mechanism 4 is located at both ends of the upper conveying mechanism 3 and is used for loading and unloading the positioning plates 2. The lifting and conveying mechanism 4 includes a lifting drive component 41, a lifting guide component 42, and a horizontal conveying component 43. The lifting drive component 41 is a telescopic cylinder component fixed to the bottom of the fixed frame 1, and the horizontal conveying component 43 is fixed to the output end of the output shaft of the lifting drive component 41.

[0062] The horizontal conveyor 43 and the first conveyor assembly 31 have the same structure, both being belt drive structures. The top of the horizontal conveyor 43 also has a limiting baffle 431 on the side away from the first conveyor assembly 31, which is used for limiting and abutting the positioning plate 2.

[0063] The lifting guide 42 is used to guide the lifting movement of the horizontal conveyor 43. The lifting guide 42 includes a fixed plate 421 sleeved on the output end of the lifting drive 41, a plurality of fixed shafts 422 connecting the fixed plate 421 and the fixed frame 1, a plurality of guide rods 423 passing through the fixed plate 421, and a lifting plate 424 disposed at the end of the guide rods 423. The upper and lower end faces of the lifting plate 424 are fixed to the horizontal conveyor 43 and the lifting drive 41, respectively.

[0064] Combination Figure 9 Below the upper conveying mechanism 3, the fixed frame 1 is also equipped with a lower conveying mechanism 5, which has the opposite conveying direction to the upper conveying mechanism 3. The lower conveying mechanism 5 is used to retrieve the assembled positioning plate 2 and re-transport the positioning plate 2 to the lifting conveying mechanism 4 located at the starting end of the upper conveying mechanism 3.

[0065] The lower conveying mechanism 5 and the upper conveying mechanism 3 are arranged in parallel and have the same structure as the first conveying assembly 31. The lower conveying mechanism 5 also has a baffle assembly 33 at one end near the upper conveying mechanism 3. The lower conveying mechanism 5 has a mounting bracket 51 for mounting the baffle assembly 33. The bottom of the positioning plate 2 has a positioning slide 25 for the baffle assembly 33 of the lower conveying mechanism 5 to abut against, with the positioning slide groove and positioning slot 24 corresponding to each other.

[0066] The lifting drive 41 gives the horizontal conveyor 43 a first height and a second height. When the horizontal conveyor 43 is at the first height, it corresponds to the upper conveyor mechanism 3 so that the horizontal conveyor 43 can be activated to transport the positioning plate 2 to the upper conveyor mechanism 3. When the horizontal conveyor 43 is at the second height, it corresponds to the lower conveyor mechanism 5 so that the horizontal conveyor can receive the positioning plate 2 from the lower conveyor mechanism 5.

[0067] Reference Figure 9 The high-frequency heating mechanism 6 includes a high-frequency heating bracket 61, a heating lifting component 62 disposed on the high-frequency heating bracket 61, a heating coil 63 mounted on the heating lifting component 62, and a rotor sleeve 64 for insertion into the housing 91.

[0068] The heating lifting component 62 includes a first linear module 621 and a heating lifting frame 622 that is lifted and mounted on the first linear module 621. The heating coil 63 is spirally arranged and is used to be sleeved on the outside of the housing 91. The heating lifting frame 622 is provided with coil clamps 623 for fixing the two ends of the heating coil 63, so that the heating lifting frame 622 can drive the heating coil 63 to rise and fall synchronously.

[0069] The rotor sleeve 64 is located inside the heating coil 63 and is inserted into the housing 91 and fitted over the outside of the rotor assembly 92. The rotor sleeve 64 is made of heat-insulating material, which can isolate heat to a certain extent and protect the normal performance of the rotor assembly 92. In order to reduce heat loss, a heat-insulating frame 624 fitted over the outside of the heating coil 63 is also fixed on the heating lifting frame 622.

[0070] A guide shaft 641 is provided on the top of the rotor sleeve 64, and a guide seat 642 for sliding installation of the guide shaft 641 is fixed on the top of the heating lifting frame 622. A spring buffer 643 is also sleeved on the outside of the guide shaft 641 to reduce the damage caused by the direct impact of the rotor sleeve 64 on the inside of the housing 91.

[0071] Reference Figure 11 and Figure 12 The assembly mechanism 7 includes an assembly bracket 71, an assembly lifting component 72, a stator mounting bracket 73, and a stator pusher 74. The assembly lifting component 72 includes a second linear module 721 and an assembly lifting frame 722 that is lifted and mounted on the first linear module 621. The stator mounting bracket 73 is located at the bottom of the assembly lifting frame and is used for positioning the stator assembly 93. The stator pusher 74 includes a stator push drive component 741 disposed at the top of the assembly lifting component and a positioning push pressure head 742. The stator push drive component 741 is a linear screw drive.

[0072] The stator mounting bracket 73 includes a stator placement plate 731, a stator seat 732 mounted on the stator placement plate 731, and a stator clamping member 733. The stator placement plate 731 is horizontally fixed to the assembly lifting frame, and the stator seat is an annular sleeve, which is fixed to the stator placement plate 731 by bolts. The stator seat 732 has a blanking through hole 7321 extending through both end faces. The stator seat 732 has a wire groove notch 7322 on the side away from the assembly lifting frame, so that the coil of the stator assembly 93 can be arranged in the wire groove notch 7322, which facilitates the blanking and installation of the stator assembly 93.

[0073] The positioning push head 742 and the unloading through hole 7321 are arranged coaxially, and the inner diameter of the unloading through hole 7321 is adapted to the outer side of the stator assembly 93. The stator clamping member 733 is located at the bottom of the stator placement plate 731, and includes a first clamping plate 7331, a second clamping plate 7332, and a clamping drive member 7333. Both the first clamping plate 7331 and the second clamping plate 7332 are arc-shaped plates, and have clamping side plates 7334 on the inner side of the arc-shaped plates. The side wall of the stator seat 732 has clamping clearance holes 7323 that penetrate the two side walls and allow the clamping side plates 7334 to pass through.

[0074] Both the first clamping plate 7331 and the second clamping plate 7332 have a driving part 7335 at their ends, and each of the two sets of driving parts 7335 has a meshing gear part 7336 on one side close to each other. A connecting shaft 7337 and a connecting plate for mounting the connecting shaft 7337 are provided at the axis of the gear part 7336. The connecting plate and the stator placement plate 731 are fixedly connected.

[0075] The clamping drive component 7333 is a telescopic cylinder, which is horizontally fixed to the bottom of the assembly lifting frame. The output end of the clamping drive component 7333 is connected to one of the clamping plates, so that the drive of the clamping drive component 7333 can drive the first clamping plate 7331 and the second clamping plate 7332 to rotate in a direction away from or towards each other. In this embodiment, the clamping drive component 7333 and the drive part 7335 of the first clamping part 3432 are fixedly connected.

[0076] Reference Figure 13 The heat dissipation and ventilation mechanism 8 includes a heat dissipation shroud 81 fixed to the fixed frame 1, heat dissipation fans 82 disposed on opposite sides of the heat dissipation shroud 81, and a ventilation pipe 83 disposed on the top of the heat dissipation shroud 81. The heat dissipation shroud 81 covers the upper conveying mechanism 3 and has foil paper 811 at both ends to ensure concentrated airflow to the heat dissipation fans 82. The length of the heat dissipation shroud 81 along the upper conveying mechanism 3 is the same as the length of the three sets of positioning plates 2, so that the three sets of heated housings 91 can be cooled simultaneously, improving the overall assembly efficiency.

[0077] The implementation principle of the stator assembly housing insertion device in this application embodiment is as follows: The machine housing 91 is manually placed on the lifting conveyor 4 at the starting end of the upper conveyor 3. The lifting conveyor 4 is raised to the first height, and the horizontal conveyor 43 is activated, so that the positioning plate 2 is conveyed to the upper conveyor 3. The positioning plate 2 undergoes the heating of the machine housing 91, the assembly of the stator assembly 93 and the cooling of the machine housing 91 in sequence in the upper conveyor 3. During the operation, it is lifted by the lifting component 32 and positioned by the baffle component 33. Finally, it is conveyed to the lifting conveyor 4 at the other end. The assembled motor assembly 9 is picked up by the operator, and the positioning plate 2 is conveyed to the lower station conveyor component for recycling.

[0078] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
