Description

Technical Field

[0001] The invention belongs to the technical field of motor production and processing, and in particular relates to a device and a method for assembling a limited shrink sleeve of a motor stator and a housing. Background Art

[0002] The circular magnetic core stator is usually composed of multiple stator core blocks, which are assembled to form a complete circular stator core (such as Fig.15 This structure helps to improve the overall performance and efficiency of the motor.

[0003] When the motor is produced, the circular magnetic core stator needs to be installed into the motor housing. Currently, it is generally assembled manually or semi-manually, which has low assembly efficiency. In response to the above technical problems, the applicant has retrieved some prior arts to achieve efficient assembly of the stator and the shell. For example, the patent publication number is CN210608855U, and its main technical means is that the lifting drive mechanism drives the carrier to protrude from the top of the heater, a robot or a person places the shell on the carrier, and the stator is put on the outside of the pressing part, and then the lifting drive mechanism drives the carrier and the shell to move into the heater, the heater heats the shell carried by the carrier, so that the heated shell expands, when the temperature detector detects that the heating temperature of the heater reaches the set temperature value, the temperature detector feeds back a signal to the pressing drive mechanism, so that the pressing drive mechanism drives the pressing part and the stator to be pressed in the shell after heat expansion, thereby completing the assembly of the stator and the shell, and finally the pressing drive mechanism drives the pressing part and the assembled stator and shell to reset, so that the assembled stator and shell are synchronously moved out of the heater, so that the assembled stator and shell can be taken away. After analysis by the applicant, the disadvantage of this technical solution is that when grabbing the stator and the motor housing, due to the long-term use of the equipment, some oil stains will more or less stick to the platform for placing the motor housing and the clamp for grabbing the stator. These oil stains will absorb dust, resulting in convex spots on the platform of the motor housing and the clamp for grabbing the stator, which makes the motor housing and the stator in a tilted state during assembly. In this way, when assembling the stator and the motor housing, the concentricity of the stator and the motor housing is low, making it difficult for the stator to enter the motor housing, reducing the success rate of assembly; and the existing assembly equipment also has a pressure sensor at the pressing mechanism. If the concentricity of the stator and the motor housing is low, the pressure sensor will quickly feedback an abnormality during assembly, further reducing the success rate of assembly.

[0031] The beneficial effects of the present invention are:

[0032] 1. In the present invention, the motor housing is always kept in a vertical state by the limit plate and the positioning column, which improves the concentricity of the motor housing and the circular magnetic core stator, so that when the motor housing and the circular magnetic core stator are assembled, the motor housing can be more smoothly sleeved outside the circular magnetic core stator; at the same time, when the motor housing is assembled, the motor housing moves downward and first contacts with a plurality of rubber strips, and the motor housing moves downward along the plurality of rubber strips, and the position of the circular magnetic core stator is slowly fine-tuned by the downward pressure, so that the motor housing and the circular magnetic core stator are in a concentric position, thereby improving the assembly success rate;

At the same time, since the motor housing is in a high temperature state at this time, after contacting the rubber strip, the rubber strip slowly melts, and the motor housing is cooled by the cooler to solidify the melted rubber strip, which further improves the stability of the motor housing and the circular magnetic core stator after assembly;

[0036] 5. In the present invention, by providing a limit plate and a step, the circular core stator is kept at a distance from both ends of the motor housing after being assembled into the motor housing, so that the position of the circular core stator installed in the motor housing is more accurate, thereby indirectly improving the success rate of assembling the motor housing and the circular core stator.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Example

[0056] like Figure 1-Figure 4 , Fig.13 As shown, a motor stator and housing limited shrink sleeve assembly equipment includes a handling mechanism 1, a transfer mechanism 2, a heating mechanism 3, a pressing mechanism 4 and a cooler 5, wherein the transfer mechanism 2 is provided with a housing fixture 24 and a stator fixture 25; the equipment also includes:

[0057] Auxiliary mechanism 6, the auxiliary mechanism 6 is installed on the pressing mechanism 4, the auxiliary mechanism 6 includes a fixed box 61, a limit piece 62 is installed at the bottom of the fixed box 61, during assembly, the motor housing is sleeved outside the limit piece 62, a mounting plate 63 is installed on one side of the fixed box 61, a driving member 5 64 is installed on the mounting plate 63, and two clamping claws 65 are symmetrically installed at the output end of the driving member 5 64, and the two clamping claws 65 clamp the motor housing sleeved outside the limit piece 62;

[0058] The rubber strip 9 and the rubber strip assembly 66 are evenly arranged in the fixing box 61, and the rubber strip 9 is connected to the rubber strip assembly 66. The rubber strip 9 passes through the limiter 62. When the stator and the motor housing are assembled, the rubber strip 9 first enters the weld between two adjacent blocks on the circular magnetic core stator.

[0059] In one case of the present embodiment, the driving member 5 64 may be an air claw; the transporting mechanism 1 is provided with a transporting claw 11 for transporting the motor housing and the circular magnetic core stator; the heating mechanism 3 includes a frame 1 31, on which a driving member 2 32 is installed, the driving member 2 32 may be a cylinder, a heating tube 33 is installed at the output end of the driving member 2 32, the driving member 2 32 drives the heating tube 33 to move up and down for heating the motor housing, and a thermometer 1 34 is also installed on the frame 1 31 for detecting the temperature of the motor housing during heating, so as to determine whether the temperature of the motor housing reaches the expansion condition; the pressing mechanism 4 includes a frame 2 41, on which a driving member 3 42 is installed, the driving member 3 42 may be a cylinder for driving the auxiliary mechanism 6 to move up and down, a movable plate 43 is movably installed on the frame 2 41, the output end of the driving member 3 42 is connected to the movable plate 43, the auxiliary mechanism 6 is installed at the bottom of the movable plate 43, and the movable plate 43 is provided with two symmetrical L plates , the two L plates limit the output end of the driving member three 42, and at the same time form a gap between the output end of the driving member three 42 and the movable plate 43, and a pressure sensor 7 is installed in the gap to detect whether the pressure when the motor housing is pressed down for assembly is normal, so as to judge whether the installation of the motor housing and the circular magnetic core stator can be completed, wherein the pressure sensor 7 is connected to the external computer terminal; a plurality of coolers 5 are provided, and the output end of the cooler 5 faces the motor housing during assembly, and the assembled motor housing and the circular magnetic core stator are cooled, so that the motor housing shrinks when it is cold, so that the motor housing and the circular magnetic core stator are tightly connected, and at the same time, a thermometer 8 is also installed on the frame two 41, which is used to detect the temperature of the motor housing during cooling, so as to judge whether the motor housing reaches the contraction condition; in addition, the rubber strip 9 is made of silicone rubber, and when the rubber strip 9 is located at the weld between two adjacent blocks on the circular magnetic core stator, a part of the rubber strip 9 is located outside the weld.

[0060] In actual application of this embodiment, the motor housing and the assembled circular magnetic core stator are transported to the housing fixture 24 and the stator fixture 25 by the transport mechanism 1, and then the housing fixture 24 is transported to the bottom of the heating mechanism 3 by the transport mechanism 2, and the heating tube 33 is extended into the motor housing to heat the inside of the motor housing. At the same time, the temperature of the motor housing is detected by the thermometer 34. When the temperature reaches the temperature at which the motor housing can expand, the heating is stopped, and the housing fixture 24 is moved to the bottom of the pressing mechanism 4 by the transport mechanism 2. The auxiliary mechanism 6 on the movable plate 43 is driven downward by the driving member 3 42, so that the limiting member 62 is inserted into the motor housing, so that the assembled circular magnetic core stator has a certain distance from the upper end of the motor housing after assembly, and the driving member 3 42 is driven to move downward. Component five 64 is started so that the two clamping claws 65 clamp the motor housing sleeved outside the limiting component 62 to stabilize the motor housing, and then the stator fixture 25 is transported to the bottom of the auxiliary mechanism 6 through the transport mechanism 2, and the driving component three 42 is started so that the auxiliary mechanism 6 drives the motor housing to move downward. Before the motor housing moves downward and contacts with the circular magnetic core stator, the rubber strip 9 is moved downward by the rubber strip assembly 66 to enter the weld between two adjacent pieces on the circular magnetic core stator. The motor housing continues to move downward and contacts with a number of rubber strips 9 first, and the motor housing moves downward along the rubber strips 9. The position of the circular magnetic core stator is slowly fine-tuned by such a downward pressure, so that the motor housing and the circular magnetic core stator are in a concentric position, which improves the assembly success rate. After the downward pressure is completed, the assembly is completed;

[0061] When the motor housing moves down and contacts the rubber strip 9, the rubber strip 9 is located between the motor housing and the circular magnetic core stator, so that the motor housing and the circular magnetic core stator are tightly connected, thereby improving the stability between the motor housing and the circular magnetic core stator after assembly. At the same time, since the motor housing is in a high temperature state at this time, after contacting the rubber strip 9, the rubber strip 9 slowly melts, thereby further fixing the motor housing and the circular magnetic core stator. The cooler 5 is used to cool the motor housing so that the melted rubber strip 9 solidifies, thereby further fixing the motor housing and the circular magnetic core stator.

[0062] like Figure 7 and Fig.10 As shown, the limiting member 62 includes a limiting plate 621 and a positioning column 622 . The motor housing is sleeved on the positioning column 622 to maintain stability, and the limiting plate 621 limits the motor housing.

[0063] In actual application of this embodiment, a part of the motor housing is sleeved on the positioning column 622 and is limited by the limiting plate 621, so that the circular magnetic core stator is at a certain distance from the upper end of the motor housing after assembly; in addition, since the positioning column 622 positions the motor housing, the diameter of the positioning column 622 is the same as the diameter of the circular magnetic core stator, so that the motor housing remains in a vertical state, so that the motor housing can be concentric with the circular magnetic core stator.

[0064] Furthermore, the stator fixture 25 includes a base 251, on which a sleeve column 252 is fixed. The sleeve column 252 is provided with an annular sunken step 253. The distance from the top of the sleeve column 252 to the step 253 and the length of the positioning column 622 limit the position of the stator installed in the motor housing.

[0065] In actual application of this embodiment, the bottom of the motor housing contacts the step 253, so that the circular magnetic core stator has a certain distance from the lower end of the motor housing after assembly. The positioning column 622 and the limit plate 621 make the circular magnetic core stator have a certain distance from the upper end of the motor housing after assembly. The circular magnetic core stator is installed at a specified position in the motor housing, thereby facilitating the installation of corresponding components at both ends of the assembled motor housing.

[0066] like Figure 7 and Figure 8 As shown, an expansion and cutting assembly 623 is installed on the positioning column 622, and the expansion and cutting assembly 623 includes a driving member 6231 and a turntable 6232 installed on the driving member 6231. The driving member 6231 is installed in the positioning column 622, and a groove 6221 is provided on the positioning column 622. The turntable 6232 is located in the groove 6221. A plurality of extrusion blocks 6233 are arranged in a ring shape on the outer periphery of the turntable 6232. When the extrusion blocks 6233 press against the rubber strip 9, the rubber strip 9 expands outward.

[0067] In one case of this embodiment, the driving member 6231 can be a motor, and of course it can also be a hydraulic motor or other component that can output rotational power; the position where the rubber strip 9 passes through the positioning column 622 is a short distance away from the edge of the positioning column 622, so that the rubber strip 9 can be easily expanded outward. Fig.14 As shown, a portion of the rubber strip 9 is located in the groove 6221 to facilitate extrusion by the extrusion block 6233 .

[0068] In actual application of this embodiment, the driving member 6231 drives the turntable 6232 to rotate, so that the extrusion block 6233 at each position rotates to the rubber strip 9 adjacent to the extrusion block 6233, and squeezes the rubber strip 9 to expand it outward, so that it is convenient for the rubber strip 9 to enter the weld between two adjacent blocks on the stator of the circular magnetic core. At the same time, the motor housing can also contact the rubber strip 9 when moving downward.

[0069] Furthermore, a plurality of cutting blades 6234 are provided in a ring shape on the outer periphery of the rotating disk 6232 , and when the cutting blades 6234 touch the rubber strip 9 , the rubber strip 9 is cut.

[0070] In one case of this embodiment, the cutting blade 6234 is located between two adjacent extrusion blocks 6233 , and a gap is left between the cutting blade 6234 and the adjacent extrusion blocks 6233 , and this gap facilitates the downward movement of the rubber strip 9 without interference.

[0071] In actual application of this embodiment, after the motor housing and the circular magnetic core stator are assembled, the driving member 6231 drives the turntable 6232 to rotate, so that the cutting blade 6234 at each position rotates to the rubber strip 9 adjacent to the cutting blade 6234, and the rubber strip 9 is cut to disconnect it.

[0072] like Fig. 9 , Fig.11 and Fig.12 As shown, the transfer mechanism 2 includes a displacement substrate 21, on which a driving member 22 is installed, on which a moving plate 23 is installed, a shell fixture 24 and a stator fixture 25 are both installed on the moving plate 23, and a shading sheet 26 and a shading sheet 27 are respectively installed on the sides of the moving plate 23, and a slot switch sensor 1 261, a slot switch sensor 2 262 and a slot switch sensor 3 271 are respectively installed on the displacement substrate 21, the slot switch sensor 1 261 and the slot switch sensor 2 262 are used in conjunction with the shading sheet 1 26, and the slot switch sensor 3 271 is used in conjunction with the shading sheet 2 27, wherein the length of the shading sheet 2 27 is greater than that of the shading sheet 1 26, the slot switch sensor 1 261 and the slot switch sensor 2 262 are on the same horizontal line, and the slot switch sensor 3 271 is below the horizontal line of the slot switch sensor 1 261 and the slot switch sensor 2 262.

[0073] In one case of this embodiment, the displacement substrate 21 equipped with the driving member 1 22, the slot switch sensor 1 261, the slot switch sensor 2 262, the slot switch sensor 3 271, the shading sheet 1 26 and the shading sheet 2 27 are all prior art, and this application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, and does not affect the integrity of this application. The shading sheet 1 26 is used to shield the slot switch sensor 1 261 and the slot switch sensor 2 262 to control the driving member 1 2 2 stops, and uses the shading sheet 27 to block the slot switch sensor 3 271 to control the driving member 1 22 to stop; the driving member 1 22 can be a motor; in addition, the position of the shading sheet 27 is close to the symmetry line of the stator fixture 25, so as to ensure that when the shading sheet 27 blocks the slot switch sensor 3 271, the stator fixture 25 is located directly below the auxiliary mechanism 6; in addition, a plurality of elastic members 28 are provided between the moving plate 23 and the displacement substrate 21, and the elastic members 28 can be springs, so as to provide a buffer when the motor housing and the circular magnetic core stator are assembled.

[0074] In actual application of this embodiment, when the motor housing is clamped by the auxiliary mechanism 6, the moving plate 23 is driven by the driving member 22 to drive the stator fixture 25 and the housing fixture 24 to move back. When the shading sheet 27 blocks the slot switch sensor 3 271, the driving member 22 stops and the stator fixture 25 stops directly under the auxiliary mechanism 6, so that the motor housing and the circular magnetic core stator are concentric, which improves the success rate of assembling the motor housing and the circular magnetic core stator. At the same time, the motor housing moves downward along a plurality of rubber strips 9 to make the motor housing and the circular magnetic core stator more concentric, further improving the success rate of assembling the motor housing and the circular magnetic core stator.

[0075] like Fig.10 As shown, a plurality of limiting rods 254 are provided at the top edge of the sleeve 252. When the stator is mounted on the stator fixture 25, the limiting rods 254 are stuck in the weld between two adjacent blocks on the circular magnetic core stator.

[0076] In one case of this embodiment, the position of the limiting rod 254 and the position of the rubber strip 9 are staggered, but both are located at the weld between two adjacent blocks on the circular magnetic core stator.

[0077] In actual application of this embodiment, when the circular magnetic core stator is placed on the sleeve 252, the limiting rod 254 positions the circular magnetic core stator so that the rubber strip 9 can more smoothly enter the weld between two adjacent blocks on the circular magnetic core stator.

[0078] like Figure 5-Figure 6 As shown, a motor stator and housing limiting heat sleeve assembly device provided by the present invention, the rubber strip assembly 66 includes:

[0079] A plurality of reeling rollers 661, the number of which is the same as the number of the rubber strips 9, the reeling rollers 661 are rotatably mounted in the fixed box 61, and the rubber strips 9 are reeled on the reeling rollers 661;

[0080] The main guide roller 663 and the secondary guide roller 664 are fixed in the box 61 at the position corresponding to the rubber strip 9. The driving member 662 is installed. The main guide roller 663 is installed at the output end of the driving member 662. The secondary guide roller 664 is rotatably installed on the other side of the rubber strip 9. The main guide roller 663 and the secondary guide roller 664 clamp the rubber strip 9 to provide power for the displacement of the rubber strip 9.

[0081] Guide sleeves 665 , a plurality of guide sleeves 665 are arranged in the fixed box 61 , and the rubber strip 9 is pulled out from the winding roller 661 , passes through the guide sleeves 665 , and then passes between the main guide roller 663 and the secondary guide roller 664 .

[0082] In one case of this embodiment, the driving member 662 can be a motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor; the guide sleeve 665 is composed of a straight tube and a curved tube, so that the rubber strip 9 changes from a bent state to a vertical state, which is convenient for the rubber strip 9 to move downward, and at the same time straightens the rubber strip 9, and cooperates with the high temperature of the motor housing to keep the downwardly moved rubber strip 9 in a vertical state, which is convenient for the rubber strip 9 to enter the weld between two adjacent blocks on the stator of the circular magnetic core.

[0083] In actual application of this embodiment, the driving member 662 is started to rotate the main guide roller 663, so that the rubber strip 9 moves downward through squeezing with the slave guide roller 664.

[0084] like Figure 1 and Figure 2 As shown, a dust collector 35 is installed on the heating mechanism 3.

[0085] In actual application of this embodiment, when the motor housing is heated, some impurities inside it will form debris after heating. These debris will affect the insertion of the motor housing into the circular magnetic core stator. Especially when there is a pressure sensor 7 for detection, if there is any obstruction, it may be detected that the assembly is unsuccessful. The vacuum cleaner 35 will suck these debris out of the motor housing to prevent the debris from affecting the assembly of the motor housing and the circular magnetic core stator.

[0088] Step S2: the driving member 22 drives the moving plate 23 to drive the stator fixture 25 and the shell fixture 24 to move until the shell fixture 24 moves to the bottom of the heating mechanism 3;

[0090] Step S4: starting the vacuum cleaner 35 to vacuum the heated motor housing to remove the generated debris from the motor housing;

[0091] Step S5: the driving member 1 22 drives the moving plate 23 to drive the stator fixture 25 and the housing fixture 24 to move until the housing fixture 24 moves to the bottom of the pressing mechanism 4, and then the pressing mechanism 4 is started to move downward, so that the positioning column 622 is inserted into the motor housing until the motor housing and the limit plate 621 are against each other, and then the driving member 5 64 is started to make the two clamps 65 clamp the motor housing;

[0092] Step S6: the driving member 22 drives the moving plate 23 to drive the stator fixture 25 and the housing fixture 24 to move until the stator fixture 25 moves to the bottom of the pressing mechanism 4, and then the pressing mechanism 4 is started to drive the motor housing to move downward;

[0093] Step S7: before the motor housing moves downward and contacts the stator of the circular magnetic core, the driving member 662 is started to rotate the main guide roller 663, and the slave guide roller 664 is cooperated to move the rubber strip 9 downward, and the driving member 4 6231 is started to rotate the turntable 6232, until the extrusion block 6233 presses the rubber strip 9 at the position corresponding to the extrusion block 6233, so that the rubber strip 9 is expanded outward, until the rubber strip 9 enters the weld between two adjacent blocks on the stator of the circular magnetic core;

[0094] Step S8: The motor housing moves downward and first hits a plurality of rubber strips 9 that are spread outward, and the motor housing moves downward along the plurality of rubber strips 9 and is sheathed outside the circular magnetic core stator until the motor housing abuts against the step 253;

[0095] Step S9: At this time, the driving member 6231 is started to rotate the rotating disk 6232, so that the extruding block 6233 is away from the rubber strip 9, and at the same time, the cutting blade 6234 slowly approaches the rubber strip 9 to cut the rubber strip 9;

[0096] Step S10: At this time, the pressing mechanism 4 is started to drive the auxiliary mechanism 6 to move upward, so that the assembled motor housing and the circular magnetic core stator are located at the stator fixture 25, and the driving member 22 is started to drive the moving plate 23 to drive the stator fixture 25 and the housing fixture 24 to move, and the assembled motor housing and the circular magnetic core stator are moved to the next processing step to complete the assembly.
