For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0065] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present utility model.

[0066] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and act on the rotor to form a magneto-electrical rotation torque. A motor usually includes a stator, a rotor, and a housing. During the assembly process of the stator and the housing, the housing usually needs to be heated to a certain temperature to achieve an interference fit between the outer ring of the stator and the inner ring of the housing. However, the assembly efficiency of the stator and the housing is not high.

[0067] In view of this, the embodiment of the utility model provides a shrink-fit device, which can facilitate the loading of the stator and the housing through the product tooling mechanism, and can realize the positioning of the stator and the housing during the loading process, without the need for camera detection, and the operation is simpler and more convenient, effectively improving the assembly effect. Moreover, the heating of the housing and the assembly of the stator and the housing are carried out separately, so that the housing can be heated separately, preventing the loss of heat during the simultaneous operation, improving the heating efficiency, and further improving the assembly efficiency.

[0068] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0069] like Figures 1 to 4 As shown, the embodiment of the utility model provides a heat-shrink device, which has a heat-shrink station and an assembly station arranged in sequence, and the heat-shrink device includes:

[0070] The product fixture mechanism 100 has a positioning portion for positioning the stator and the housing;

[0071] The tooling driving mechanism 200 is drivingly connected to the product tooling mechanism 100 so as to switch the product tooling mechanism 100 between the initial station, the shrink fitting station and the assembly station;

[0072] The heat-shrink mechanism 300 is arranged corresponding to the heat-shrink station, and the heat-shrink mechanism 300 has a heating part for heating the housing;

[0073] The assembling mechanism 400 is arranged corresponding to the assembling station, and the assembling mechanism 400 has a pressing part for pressing the stator into the interior of the heated casing.

[0074] In the technical solution adopted in this embodiment, the product tooling mechanism 100 is set up to facilitate the loading of the stator and the housing, and the positioning of the stator and the housing can be achieved during the loading process, without the need for camera detection, and the operation is simpler and more convenient, which can effectively improve the assembly efficiency. The tooling drive mechanism 200 drives the product tooling mechanism 100 to move, and when it moves to the heat-fitting station, the heat-fitting mechanism 300 can separate the housing and the product tooling mechanism 100 and heat the housing. Then, the product tooling mechanism 100 moves toward the assembly station driven by the tooling drive mechanism 200, and the assembly mechanism 400 separates the stator and the product tooling mechanism 100. Afterwards, the product tooling mechanism 100 moves toward the heat-fitting station, and at the heat-fitting station, the heat-fitting mechanism 300 places the heated housing on the product tooling mechanism 100. Subsequently, the product tooling mechanism 100 moves toward the assembly station, where the assembly mechanism 400 drives the stator to be pressed into the interior of the heated casing, thereby realizing the assembly of the stator and the casing, replacing manual operation, effectively improving the assembly efficiency, and the entire assembly process is safe and stable; at the same time, the heating of the casing and the assembly of the stator and the casing are carried out separately, so that the casing can be heated separately, preventing heat loss during simultaneous operation, improving the heating efficiency, and further improving the assembly efficiency.

[0075] In one embodiment, referring to Figures 1 to 3 The shrink fitting device also includes a workbench 600, the product tooling mechanism 100, the tooling drive mechanism 200, the shrink fitting mechanism 300 and the assembly mechanism 400 are all arranged on the workbench 600, and the workbench 600 has an initial station, a shrink fitting station and an assembly station. The tooling drive mechanism 200 can be a screw drive module, a telescopic linear module, etc., which is not limited here.

[0076] For example, refer to Figure 4 In one embodiment of the present utility model, the product tooling mechanism 100 includes:

[0077] The tooling mounting plate 110, the tooling driving mechanism 200 is drivingly connected to the tooling mounting plate 110;

[0078] A casing tooling, movably mounted on the tooling mounting plate 110; and

[0079] The stator tooling is arranged on the tooling mounting plate 110 and is located at one side of the housing tooling. The housing tooling and the stator tooling together form a positioning portion.

[0080] Specifically, the product tooling mechanism 100 includes a tooling mounting plate 110, a housing tooling and a stator tooling. Among them, the tooling mounting plate 110 is used to provide an installation position to facilitate the installation of the housing tooling and the stator. The tooling drive mechanism 200 is connected to the tooling mounting plate 110 to drive the tooling mounting plate 110 to move and switch between the initial station, the shrink fit station and the assembly station. In one embodiment, the tooling drive mechanism 200 can be a telescopic cylinder, a screw module, etc., which is not limited here.

[0081] The casing tooling is used to place or position the casing, and the casing tooling is movably arranged on the tooling mounting plate 110. It can be understood that when the shrink fitting mechanism 300 separates the casing and the product tooling mechanism 100, it is achieved by separating the casing tooling from the tooling mounting plate 110. In order to facilitate the shrink fitting mechanism 300 to separate the casing tooling from the tooling mounting plate 110, a cam 140 is provided on the casing tooling. When the tooling mounting plate 110 moves to the shrink fitting station, the shrink fitting mechanism 300 cooperates with the cam 140 to lift the casing tooling from the tooling mounting plate 110, thereby realizing the separation of the casing and the tooling mounting plate 110. In one embodiment, the cam is arranged on the side wall of the casing tooling, and the shrink fitting mechanism 300 has a hook hanging groove for accommodating the cam. The casing tooling is lifted from the tooling mounting plate 110 by the cooperation between the cam and the hook hanging groove.

[0082] Optionally, the casing tooling includes a casing bottom plate 121, and the casing bottom plate 121 and the tooling mounting plate 110 are provided with a pressing avoidance space, and the pressing avoidance space is used for the telescopic module 462 to pass through. The surface of the casing bottom plate 121 facing away from the tooling mounting plate 110 is provided with a follower block 122, and multiple follower blocks 122 are provided along the circumference of the pressing avoidance space. The casing is placed in the space surrounded by multiple follower blocks 122, thereby realizing the positioning of the casing.

[0083] A housing support plate 123 is provided on the surface of the housing bottom plate 121 facing the tooling installation plate 110 . The housing support plate 123 is movably connected to the tooling installation plate 110 . The hook structure 140 is provided on the side of the housing support plate 123 .

[0084] The stator fixture is used to place or position the stator and is arranged on one side of the housing fixture. In one embodiment, the stator fixture includes a stator positioning protrusion 131 and a stator positioning ring 132 arranged outside the stator positioning protrusion 131, and a stator positioning space is formed between the stator positioning protrusion 131 and the stator positioning ring 132, and the stator is placed in the stator positioning space.

[0085] Illustratively, in one embodiment of the present invention, the product tooling mechanism 100 further includes a tooling positioning structure, and the housing tooling is movably connected to the tooling mounting plate 110 via the tooling positioning structure.

[0086] Specifically, the tool positioning structure is used to realize the installation and positioning of the casing tool on the tool mounting plate 110, and the accurate assembly of the casing tool on the tool mounting plate 110 is improved by the tool positioning structure. In one embodiment, the tool positioning structure can be a mounting groove provided on the tool mounting plate 110, and the casing tool is directly placed in the mounting groove, and the inner wall of the mounting groove is used to realize the positioning of the casing installation. Of course, the tool positioning structure can also be a plurality of positioning rods provided on the tool mounting plate 110, and the plurality of positioning rods enclose a positioning space. The casing tool is provided in the positioning space and abuts against the positioning rods, which can also realize the positioning of the casing tool.

[0087] Illustratively, in one embodiment of the utility model, the shrink fitting device further includes an assembly limiting structure 500, which is arranged on the product tooling mechanism 100. The assembly limiting structure 500 has a limiting abutment portion. During the process of pressing the stator into the interior of the casing, the limiting abutment portion of the assembly limiting structure 500 abuts against the stator to limit the depth of the stator being pressed into the casing.

[0088] Specifically, by using the assembly limiting structure 500, the stator can be positioned during the assembly process to prevent the stator from not being pressed into the predetermined position or being over-pressed, thereby improving the accuracy of the assembly of the stator and the housing and reducing the failure rate.

[0089] Illustratively, in one embodiment of the present invention, the combined limiting structure 500 is detachably connected to the tooling mounting plate 110 .

[0090] In order to improve versatility, the combined assembly limiting structure 500 is detachably connected to the tooling installation plate 110. In this way, the corresponding combined assembly limiting structure 500 can be replaced according to the production of different types of products to control the depth of the stator inserted into the housing, so that it can be compatible with a variety of different types of products and is suitable for mass production. In one embodiment, the combined assembly limiting structure 500 can be detachably connected to the tooling installation plate 110 by buckles, bolts, etc., which are not limited here.

[0091] Illustratively, in one embodiment of the utility model, the assembly limit structure 500 includes a limit support plate, one end of which is connected to the tooling mounting plate 110, and the other end of the limit support plate extends through the pressing avoidance space toward the assembly mechanism 400, and the limit support plate forms a limit abutment portion.

[0092] Specifically, the assembly limiting structure 500 includes a limiting support plate, which is arranged in the press-fit avoidance space and extends in a direction away from the tooling installation plate 110. One end of the limiting support plate is connected to the tooling installation plate 110, and the other end of the limiting support plate extends toward the casing tooling and passes through the press-fit avoidance space. The limiting support plate is used for abutment positioning to limit the depth of the stator inserted into the casing. In one embodiment, a plurality of limiting support plates are arranged at intervals along the circumference of the press-fit avoidance space to abut different positions of the stator to improve the uniformity of the force on the stator.

[0093] For example, refer to Figures 5 to 7 In one embodiment of the present utility model, the shrink fitting mechanism 300 includes:

[0094] The heater 310 is disposed above the shrink fitting station, and the heater 310 forms a heating portion;

[0095] The gripping portion 320 is disposed below the heater 310, that is, on the side of the heater 310 facing the ground, and is used to grip the casing tooling;

[0096] The heat-shrink transfer assembly 330 is driven and connected to the gripping portion 320 so that the casing tooling moves toward the heater 310 so that the heater 310 is inside the casing, or the casing tooling moves away from the heater 310 so that the casing tooling is placed on the tooling mounting plate 110.

[0097] Specifically, the heat-shrink mechanism 300 includes a heater 310, a gripping portion 320, and a heat-shrink transfer assembly 330. The heater 310 is arranged above the heat-shrink station, the gripping portion 320 is arranged below the heater 310, and the heat-shrink transfer assembly 330 and the gripping portion 320 are drivingly connected to drive the gripping portion 320 to move closer to or away from the heater 310. It can be understood that when the tooling mounting plate 110 moves to the heat-shrink station, the housing tooling is located below the heater 310 and above the gripping portion 320. At this time, the heat-shrink transfer assembly 330 drives the gripping portion 320 to move toward the heater 310, and the gripping portion 320 cooperates with the hook structure 140 on the housing tooling, so that the housing tooling is lifted off the tooling mounting plate 110 until the housing moves to the outside of the heater 310, that is, the heater 310 is located inside the housing, and the heater 310 works to heat the housing. After the casing tooling is lifted off the tooling mounting plate 110, the tooling mounting plate 110 continues to move toward the assembly station, that is, the stator moves toward the assembly station. In one embodiment, the gripping portion 320 is a support plate. Of course, in other embodiments, the gripping portion 320 can also be a gripper or a clamp, etc., which is not limited here.

[0098] In one embodiment, referring to Figure 6The shrink fitting transfer assembly 330 includes a shrink fitting screw rod 331, a shrink fitting transfer plate 332 and a lifting plate 333, wherein the shrink fitting screw rod 331 is arranged above the shrink fitting station in the vertical direction, the shrink fitting transfer plate 332 is sleeved on the outside of the shrink fitting screw rod 331 and is threadedly connected to the shrink fitting screw rod 331, and the lifting plates 333 are arranged at opposite ends of the shrink fitting transfer plate 332 and extend along the movement direction of the product tooling mechanism 100. Each lifting plate 333 is provided with a gripping portion 320. When the tooling mounting plate 110 moves to the shrink fitting station, the casing is located between the two lifting plates 333, and the gripping portion 320 is located below the hook structure 140 of the casing tooling. In this way, the heat-shrink transfer plate 332 moves toward the heater 310 under the drive of the heat-shrink screw 331, and the lifting plate 333 moves synchronously with the heat-shrink transfer plate 332, so that the gripping portion 320 grabs the hook structure 140, thereby driving the casing tooling to move toward the heater 310 and separate from the tooling mounting plate 110. In one embodiment, a plurality of gripping portions 320 are provided at intervals along the extension direction of the lifting plate 333, so that the stability of the casing tooling being lifted off the tooling mounting plate 110 can be improved. As an optional method, the heat-shrink transfer assembly 330 also includes a heat-shrink guide rail 334, which is arranged parallel to the heat-shrink screw 331, and the heat-shrink transfer plate 332 is slidably arranged on the heat-shrink guide rail 334, which can guide the movement of the heat-shrink transfer plate 332. Optionally, the shrink fit transfer assembly 330 further includes a shrink fit connection block, which is sleeved on the outside of the shrink fit screw rod 331 and threadedly connected to the shrink fit screw rod 331 , and the shrink fit transfer plate 332 is connected to the shrink fit connection block.

[0099] Exemplarily, in one embodiment of the present utility model, referring to Figure 5 The heat sleeve mechanism 300 also includes a heat sleeve bracket 340, which has a heat sleeve space and a heat sleeve avoidance port connected to the heat sleeve space, and the heat sleeve avoidance port faces the casing tooling. In order to facilitate the positioning of the casing, a heat sleeve bracket 340 is provided, and the heat sleeve bracket 340 has a heat sleeve space and a heat sleeve avoidance port connected to the heat sleeve space, and the heater 310 is provided on the top of the heat sleeve bracket 340. When the heat sleeve transfer plate 332 moves toward the heater 310, the casing tooling enters the heat sleeve space through the heat sleeve avoidance port for heating. In one embodiment, referring to Figure 7The heat sleeve bracket 340 includes a heat sleeve bottom plate 342, a heat sleeve top plate 341, and a heat sleeve support column 343 connecting the heat sleeve top plate 341 and the heat sleeve bottom plate 342. The heat sleeve bottom plate 342 is connected to the workbench 600. The heater 310 is arranged on the heat sleeve top plate 341. There are multiple heat sleeve support columns 343. The multiple heat sleeve support columns 343 form a heat sleeve space. The heat sleeve bottom plate 342 is provided with a heat sleeve avoidance.

[0102] A clamping assembly 410 having a clamping portion for clamping or releasing the stator; and

[0103] The assembly drive assembly 420 is drivingly connected to the clamping assembly to move the clamping assembly 410 toward or away from the tooling mounting plate 110 .

The clamping portion of the clamping assembly 410 is used to clamp or release the stator, and the assembly drive assembly 420 is connected to the clamping assembly 410 to drive the clamping assembly 410 to move toward or away from the tooling mounting plate 110, thereby lifting the stator from the stator tooling or pressing the stator into the heated housing. In one embodiment, the assembly drive assembly 420 can be a screw drive module, a lifting adjustment module, a telescopic adjustment module, etc., which are not limited here.

When the tooling mounting plate 110 moves toward the assembly station, the stator on the stator tooling enters the assembly space through the assembly opening.

[0106] In one embodiment, referring to Fig.10 The assembly bracket 430 includes an assembly top plate 431, an assembly bottom plate 432 and an assembly support shaft 433 connecting the assembly top plate 431 and the assembly bottom plate 432.

The assembly bottom plate 432 is provided with a connecting hole to communicate with the assembly avoidance space. The assembly drive assembly 420 is arranged on the assembly top plate 431, and the assembly bottom plate 432 is connected to the workbench 600.

[0107] To facilitate the assembly of the driving assembly 420 and the clamping assembly 410, the assembly bracket 430 further includes a first assembly transfer plate 434. Fig.10 The first assembly transfer plate 434 is connected to the assembly drive assembly 420 , and the clamping assembly 410 is connected to the first assembly transfer plate 434 , that is, the clamping assembly 410 is connected to the assembly drive assembly 420 through the first assembly transfer plate 434 .

[0108] In order to guide the movement of the first assembly transfer plate 434, the assembly bracket 430 further includes an assembly guide rod 435 arranged in the vertical direction. Fig.10 The assembly guide rod 435 penetrates the first assembly transfer plate 434, and the first assembly transfer plate 434 is slidably sleeved on the outside of the assembly guide rod 435, so that the assembly guide rod 435 is used to guide the lifting movement of the first assembly transfer plate 434. As an optional method, an assembly linear bearing 436 is slidably provided on the assembly guide rod 435, and the first assembly transfer plate 434 is connected to the assembly linear bearing 436, so that the resistance of the first assembly transfer plate 434 when sliding along the assembly guide rod 435 can be reduced.

[0109] Exemplarily, in one embodiment of the present utility model, referring to Fig. 9 , the clamping assembly 410 includes:

[0110] The linear motion module 411 is assembled with a driving assembly 420 and is drivingly connected to the linear motion module 411;

[0111] A movable block 412, the movable block 412 is tilted in a direction close to the assembly station and away from the linear motion module 411, and the linear motion module 411 is drivingly connected to the movable block 412; and

[0112] The abutment member 413 is connected to the movable block 412 . The abutment member 413 moves with the movable block 412 and has a horizontal displacement to abut against the inner wall of the stator. The abutment member forms a clamping portion.

[0113] In this embodiment, the clamping assembly 410 includes a linear motion module 411, a movable block 412 and an abutment 413. The assembly drive assembly 420 is connected to the linear motion module 411. It can be understood that the linear motion module 411 is connected to the first assembly transfer plate 434 and moves synchronously with the first assembly transfer plate 434. The movable block 412 is connected to the linear motion module 411, the movable block 412 is tilted, and the linear motion module 411 and the abutment 413 are arranged at opposite ends of the movable block 412. Specifically, the assembly drive assembly 420 can drive the linear motion module 411 to move toward the tooling installation plate 110 until the linear motion module 411 moves to the predetermined assembly position. At this time, the movable block 412 and the abutment 413 are located inside the stator, and the linear motion module 411 works to drive the movable block 412 and the abutment 413 to move toward the tooling installation plate 110. Since the movable block 412 is tilted, the vertical stroke of the linear motion module 411 can be converted into a horizontal stroke, so that the abutment member 413 is pressed against the inner wall of the stator. Afterwards, the assembly drive assembly 420 works, and can drive the first assembly transfer plate 434 to move toward or away from the tooling mounting plate 110, thereby pressing the stator into the interior of the heated casing or lifting it off the stator tooling. When the stator is lifted off the stator tooling, the tooling mounting plate 110 moves toward the shrink fitting station, and the shrink fitting mechanism 300 places the casing tooling and the heated casing on the tooling mounting plate 110. Subsequently, the tooling mounting plate 110 moves toward the assembly station, and the assembly drive assembly 420 works, driving the first assembly transfer plate 434 to move toward the tooling mounting plate 110, so that the stator is pressed into the interior of the heated casing. Optionally, a plurality of abutment members 413 are provided in a circular array, each abutment member 413 is provided with a corresponding movable block 412, and all movable blocks 412 are connected to the linear motion module 411, so that they can be tightly pressed against different positions of the inner wall of the stator to improve the reliability of clamping.

[0114] As an optional manner, the angle between the movable block 412 and the vertical direction is 5 degrees.

[0115] In one embodiment, referring to Fig. 9The clamping assembly 410 also includes an assembly frame 414, which is connected to the first assembly transfer plate 434 and can move synchronously with the first assembly transfer plate 434. The linear motion module 411 is arranged inside the assembly frame 414 and connected to the assembly frame 414. An assembly guide rail is arranged inside the assembly frame 414, and the movable block 412 is slidably connected to the assembly guide rail. A through hole is arranged on the top of the assembly frame 414, and the movable block 412 is slidably penetrated in the through hole, and the abutment member 413 is arranged below the assembly frame 414. As an optional method, the clamping assembly 410 also includes an assembly guide base plate 415 and an assembly guide side plate 416, the assembly guide side plate 416 connecting the bottom of the assembly frame 414 and the assembly guide base plate 415, and a plurality of assembly guide side plates 416 are arranged at intervals along the circumference of the assembly frame 414, and the abutment 413 is arranged between two adjacent assembly guide side plates 416, so that the abutment 413 can be limited by the assembly guide side plate 416.

[0116] Exemplarily, in one embodiment of the present utility model, referring to Fig. 9 The assembly mechanism 400 further includes an assembly positioning structure 440, which has an assembly positioning portion, which is connected to the clamping assembly 410 and is used to abut against the stator to limit the movement distance of the clamping assembly 410 toward the assembly station.

[0117] In order to ensure that the linear motion module 411 moves to the predetermined assembly position, an assembly positioning structure 440 is provided. It is understandable that the assembly drive assembly 420 drives the first assembly transfer plate 434 to move toward the tooling installation plate 110 until the assembly positioning structure 440 abuts against the top of the stator (i.e., the end of the stator away from the tooling installation plate 110), at which time, the linear motion module 411 moves to the predetermined position. In one embodiment, the assembly positioning structure 440 is an assembly limit plate, one end of which is connected to the assembly frame 414, and the other end of which extends toward the abutment member 413.

[0118] Exemplarily, in one embodiment of the present utility model, referring to Figure 8 The assembly mechanism 400 further includes a heat dissipation assembly 470, which is disposed below the clamping assembly 410 and is used to dissipate heat from the assembled stator and housing. In this way, after the stator is pressed into the housing, the assembled stator and housing can dissipate heat, thereby improving the cooling efficiency.

[0119] Exemplarily, in one embodiment of the present utility model, referring to Fig.10 The heat dissipation assembly 470 includes a blowing structure 471 and an exhaust structure 472 disposed above the blowing structure 471. The blowing structure 471 and the exhaust structure 472 cooperate to dissipate heat from the assembled stator and the housing.

[0120] Specifically, the blowing structure 471 can blow air below the assembled stator and housing, and the exhaust structure 472 can suck air above the assembled stator and housing, thereby accelerating the flow of air and cooling the stator as quickly as possible. As an optional method, the blowing structure 471 is a fan, and the exhaust structure 472 is a centrifugal fan.

[0121] Exemplarily, in one embodiment of the present utility model, referring to Fig.10 The assembly mechanism 400 further includes a pressure detection structure 450, which is disposed between the clamping assembly 410 and the assembly drive assembly 420 to detect the pressure during the process of pressing the stator into the casing.

[0122] In order to reduce the failure of the assembly device and ensure normal operation, a pressure detection structure 450 is provided, through which the force applied to the assembly drive assembly 420 can be detected, thereby determining whether there is a failure in the assembly process, and further controlling the working state of the assembly drive assembly 420. As an optional method, the pressure detection structure 450 is a pressure sensor, which is provided on the first assembly transfer plate 434 and is located between the first assembly transfer plate 434 and the assembly drive assembly 420.

[0123] Specifically, when the stator and the housing are assembled, if the stator fails to be vertically pressed into the interior of the housing, that is, the stator is stuck, the assembly drive assembly 420 drives the clamping assembly 410 to continue to move downward, the value of the pressure sensor changes greatly and exceeds the predetermined value, and the assembly drive assembly 420 stops working and reports an error. If the abutment 413 of the clamping assembly 410 slips against the inner wall of the stator and cannot completely clamp the stator, at this time, the assembly drive assembly 420 drives the clamping assembly 410 to continue to move downward, the assembly positioning structure 440 abuts against the top of the stator, the value of the pressure sensor changes greatly and exceeds the predetermined value, and the assembly drive assembly 420 stops working and reports an error. In the above manner, the accuracy of assembly is improved and the failure rate can be reduced.

[0124] Exemplarily, in one embodiment of the present utility model, referring to Figure 8, the assembly mechanism 400 also includes a position adjustment component 460, which is arranged on the side of the casing tooling facing the ground. The position adjustment component 460 has a telescopic adjustment part that is telescopic along the radial direction of the casing, and the telescopic adjustment part abuts against the inner wall of the casing to adjust the concentricity of the stator and the casing when assembled. In this way, the concentricity of the stator and the casing can be improved, thereby improving the accuracy of the stator being pressed into the casing and preventing the stator from getting stuck during assembly. It can be understood that the telescopic adjustment part of the position adjustment component 460 is extended and can abut against the inner wall of the casing, thereby driving the casing to move radially and improving the concentricity of the casing and the stator. In other words, when the heated casing moves to the assembly station, the position adjustment component 460 works first, and after adjusting the concentricity of the casing and the stator, the assembly drive component 420 works again to drive the stator to be pressed into the interior of the casing. As an optional method, the position adjustment component 460 is connected to the workbench 600 and is located below the workbench 600. In one embodiment, there are multiple telescopic adjustment parts, and the multiple telescopic adjustment parts are telescoped synchronously.

[0125] Exemplarily, in one embodiment of the present utility model, referring to Fig.11 The casing tooling and the tooling mounting plate 110 are provided with a pressing avoidance space, and the position adjustment component 460 includes:

[0126] The lifting module 461 is disposed on the side of the casing facing the ground; and

[0127] The telescopic module 462 and the lifting module 461 are drivingly connected to the telescopic module 462 so that the telescopic module 462 moves toward or away from the casing tooling, wherein the telescopic module 462 has a telescopic portion to abut against or separate from the inner wall of the casing.

[0128] Specifically, the position adjustment component 460 includes a lifting module 461 and a plurality of telescopic modules 462, wherein the lifting module 461 is used to drive the telescopic module 462 to lift and lower, and the telescopic module 462 is used to abut or release the casing. It can be understood that when the heated casing moves to the assembly station, the lifting module 461 works, driving the telescopic module 462 to move through the pressing avoidance space to the inside of the casing, and then the plurality of telescopic modules 462 extend at the same time, so that the plurality of telescopic modules 462 are all pressed against the inner wall of the casing, thereby adjusting the concentricity of the casing and the stator. Optionally, the lifting module 461 can be a screw transmission structure, and the telescopic module 462 can be a telescopic cylinder.

[0129] In one embodiment, referring to Fig.11The position adjustment component 460 also includes a position adjustment vertical plate 463, a second combined transfer plate 464, and a position adjustment mounting plate 465. The lifting module 461 is set on the position adjustment vertical plate 463, the second combined transfer plate 464 is connected to the lifting module 461, the position adjustment mounting plate 465 is connected to the second combined transfer plate 464, and the telescopic module 462 is set on the position adjustment mounting plate 465. The lifting module 461 drives the second combined transfer plate 464 to move up and down, and the combined mounting plate moves synchronously with the second combined transfer plate 464.

[0130] For example, refer to Fig.11 In one embodiment of the utility model, the position adjustment assembly 460 also includes an adjustment plate structure, the telescopic module 462 is arranged on the adjustment plate structure, the lifting module 461 is drivingly connected to the adjustment plate structure, and the adjustment plate structure is used to adjust the horizontal position of the telescopic module 462. In this way, the horizontal position of the telescopic module 462 can be adjusted according to actual usage to improve the adjustment accuracy of the concentricity of the stator and the casing. In one embodiment, the adjustment plate structure includes an adjustment mounting substrate 4661, a lateral adjustment plate 4662 and a longitudinal adjustment plate 4663. Among them, the adjustment mounting substrate 4661 is connected to the position adjustment mounting plate 465, the lateral adjustment plate 4662 is slidably arranged on the adjustment mounting substrate 4661, the longitudinal adjustment plate 4663 is slidably arranged on the lateral adjustment plate 4662, and the telescopic module 462 is arranged on the longitudinal adjustment plate 4663.

[0131] Exemplarily, in one embodiment of the utility model, the heat-shrink device further includes a protective structure 700, the protective structure 700 has a protective space, and the heat-shrink mechanism 300 and the assembly mechanism 400 are arranged in the protective space. By setting the protective structure 700, the internal mechanism can be protected, and personal injury can be prevented, thereby improving the safety during assembly. As an optional method, the protective structure 700 is a protective net or a safety grating.

[0132] In summary, the utility model provides a heat-shrink device for assembling the stator and rotor of a motor. The housing is placed on the housing tooling, and the stator is placed on the stator tooling. The stator and the housing can be positioned during the loading process without camera detection, and the operation is simpler and more convenient. The tooling drive mechanism drives the housing tooling and the stator tooling to switch synchronously between the initial position, the heat-shrink station, and the assembly station. When the housing tooling and the stator tooling move to the heat-shrink station, the housing tooling is located below the heater 310 and above the gripping portion 320. At this time, the heat-shrink transfer assembly 330 drives the gripping portion 320 to move toward the heater 310. The gripping portion 320 cooperates with the hook structure 140 on the housing tooling, so that the housing tooling is lifted off the tooling mounting plate 110 until the housing moves to the outside of the heater 310, that is, the heater 310 is located inside the housing, and the heater 310 works to heat the housing. After the casing tooling is lifted off the tooling mounting plate 110, the tooling mounting plate 110 continues to move toward the assembly station, that is, the stator moves toward the assembly station. The heat-fitting transfer assembly 330 is also provided with a temperature detection element 350, which monitors the temperature of the casing in real time to ensure that the temperature of the casing meets the standard. When the tooling mounting plate 110 moves to the assembly station, the assembly drive assembly 420 drives the clamping assembly 410 to move downward and clamp the stator on the casing tooling and then move upward, thereby lifting the stator from the stator tooling. Then, the tooling mounting plate 110 moves toward the heat-fitting station, and the heat-fitting transfer assembly 330 places the heated casing on the tooling mounting plate. Then, the tooling installation plate 110 moves toward the assembly station. When the tooling installation plate 110 moves to the assembly station, the assembly drive assembly 420 drives the clamping assembly 410 to move downward until the assembly limit structure 500 abuts against the bottom end of the stator, thereby ensuring that the stator is pressed into the predetermined position of the casing. During the entire assembly process of the stator and the casing, the heating of the casing and the assembly of the stator and the casing are performed separately, so that the casing can be heated separately to prevent heat loss during the simultaneous operation, improve heating efficiency, and further improve assembly efficiency. In addition, by using the provided assembly limit structure 500, the stator can be positioned during the assembly process to prevent the stator from not being pressed into the predetermined position or being over-pressed, thereby improving the accuracy of the assembly of the stator and the casing and reducing the failure rate.
