Description

Technical Field

[0001] The present invention belongs to the technical field of motor assembly equipment, and particularly relates to a fully automatic press-fitting device.

Background Art

[0002] As a power source component, motors are widely used in various fields. A motor generally includes a motor housing, two end caps arranged at both ends of the motor housing, a stator arranged inside the motor housing, a rotor and other structures. When assembling a motor, it is necessary to first install the stator into the motor housing, and there are certain assembly requirements between the two, and they need to fit tightly after assembly.

[0003] In the prior art, the patent publication number CN208231206U discloses a main drive motor stator press-fitting device, which sets a positioning stop on the platform surface for positioning the motor housing, and then uses an inner support type fixture to support the stator core from the inside, and then puts it into the motor housing. At the same time, a pressing plate is arranged on the fixture, and the stator core is pressed into the motor housing from the upper end surface of the stator core by using the pressing plate to achieve automatic press-fitting. Although this press-fitting device realizes the automatic press-fitting of the stator core and the housing, it has the following several disadvantages:

[0004] (1) In actual press-fitting operations, the bottom of the stator core is in a suspended state, and only the upper end surface is subjected to axial pressure. When pressing down, the central axis of the stator core is prone to deflection, resulting in an inclined jamming situation between the circumferential surface of the stator core and the inner wall surface of the housing. On the one hand, it increases the resistance of press-fitting. On the other hand, if the jamming is serious and it is forced to be pressed in, it may cause damage to the product. If it is not pressed hard, it will lead to press-fitting failure;

[0005] (2) After the iron core is placed in the housing, before the inner support fixture is released, the position of the iron core is guaranteed. However, when the inner support fixture is released, at this time, the position state of the iron core on the housing is the initial state before press-fitting. After the inner support fixture is released, there is a gap between the iron core and the upper inner wall of the housing, which is prone to the deflection of the iron core axis and is prone to the inclined jamming phenomenon during press-fitting.

[0006] Therefore, it is necessary to provide a new fully automatic press-fitting device to solve the above problems.

[0011] Further, a plurality of second elastic members that upwardly press the first floating pressure plate are arranged between the first floating pressure plate and the base.

[0012] Further, a second floating pressure plate is vertically floatingly arranged on the lower surface of the upper pressure plate. A plurality of second riveting needles corresponding to the positions of the magnetic sheets in the iron core are arranged on the upper pressure plate. The second riveting needles are embedded in the second floating pressure plate in the initial state and protrude from the surface of the second floating pressure plate to rivet the top shaft end surface of the iron core after the distance between the second floating pressure plate and the upper pressure plate is reduced.

[0013] Further, a plurality of third elastic members that downwardly press the second floating pressure plate are arranged between the second floating pressure plate and the upper pressure plate.

[0014] Further, a second anti-rotation limiting block that cooperates with a groove on the inner hole wall of the iron core to achieve angular positioning is arranged on the first positioning block.

[0015] Further, it further includes a housing handling mechanism for handling the housing onto the lower support assembly, a core handling mechanism for handling the core into the lower support assembly, and an oiling mechanism for oiling the inner wall of the housing.

[0016] Further, the housing handling mechanism includes a second driving member, a first support plate driven by the second driving member to move horizontally, a second cylinder disposed on the first support plate, a third cylinder driven by the second cylinder to move up and down, a fourth cylinder driven by the third cylinder to rotate about a horizontal axis, and a first jaw driven by the fourth cylinder to open or clamp.

[0019] (1) By providing a movable support base that moves up and down on a fixed support base for supporting the housing, for supporting the core; through the setting of the movable support base, on the one hand, the initial position state (including the central axis and the angular position) when the core is placed can be accurately controlled and maintained, providing an important basis for the subsequent accurate press-in of the core to prevent it from skewing and jamming.

[0020] (2) On the other hand, it can provide full axial support for the press-fitting process of the core. The vertical state of the core axis is ensured by the first positioning block at the lower part and the second positioning block at the upper part, effectively preventing the press-fitting force from not being collinear with the axis of the core, resulting in damage to the core or the housing, or even the phenomenon of the core being stuck with the housing, leading to product scrapping.

At the same time, a rotation stop and limit block for preventing the housing from rotating and shifting is provided in the press-fitting mechanism. The rotation stop and limit block of the press-fitting mechanism has an up-and-down floating function. On the one hand, it can guide and correct the angular position of the housing before press-fitting. On the other hand, it can maintain the angular position of the housing during the press-fitting process without affecting the press-fitting process, effectively improving the assembly accuracy of the housing and the iron core.

Detailed implementation manners

[0038] Example:

[0039] Please refer to Figures 1 - 8 , this embodiment is a fully automatic press - fitting device 100, which includes a lower support assembly 1, a press - fitting mechanism 2 arranged above the lower support assembly 1, a housing handling mechanism 3 for transporting the housing 200 to the lower support assembly 1, an iron - core handling mechanism 4 for transporting the iron core 300 into the lower support assembly 1, and an oil - applying mechanism 5 for applying oil to the inner wall of the housing 200.

[0040] In order to ensure that the iron core 300 can be smoothly and vertically pressed into the housing 200, the lower support assembly 1 is optimized in this embodiment. Specifically, the lower support assembly 1 includes a fixed support base 11, a movable support base 12 that is vertically movably arranged within the fixed support base 11, and a first cylinder 13 that drives the movable support base 12 to move up and down. A limit support groove 111 for defining the outer peripheral position of the housing 200 is provided on the fixed support base 11. The movable support base 12 moves up and down within the space range of the limit support groove 111. The movable support base 12 includes a base 121 that supports the lower end surface of the iron core 300 and a first positioning block 122 that protrudes from the surface of the base 121 and positions the inner peripheral position of the lower part of the iron core 300. During press-fitting, the movable support base 12 rises to support the iron core 300, and then as the press-fitting mechanism 2 feeds the iron core 300 and the housing 200 into the housing 200 while always maintaining a coaxial state, the perpendicularity of the axis of the iron core 300 during the press-fitting process is ensured, effectively avoiding interference jamming between the outer peripheral surface of the iron core 300 and the inner wall surface of the housing 200, and ensuring the smooth press-fitting of the iron core 300.

[0041] Since the housing 200 placed in the limit support groove 111 has no axial and rotational constraints, but the assembly of the housing 200 and the iron core 300 has angular mating requirements, therefore, in order to prevent the housing 200 from deflecting at an angle during the press-fitting process, the press-fitting mechanism 2 is optimized in this embodiment. Specifically, the press-fitting mechanism 2 includes a first driving member 21, a movable plate 22 driven by the first driving member 21 to move up and down, and a press-fitting assembly 23 fixed on the movable plate 22. The press-fitting assembly 23 includes a mounting cylinder column 231 fixed on the movable plate 22, an upper pressing plate 232 provided on the lower end surface of the mounting cylinder column 231, and a second positioning block 233 that protrudes from the lower surface of the upper pressing plate 232 and positions the inner peripheral position of the upper part of the iron core 300. A first anti-rotation limit block 234 that is vertically movably arranged on the mounting cylinder column 231 and engages with a corresponding notch 201 on the housing 200 during the press-fitting process is provided on the outer peripheral surface of the mounting cylinder column 231. The width of the first anti-rotation limit block 234 is equivalent to the width of the notch 201. During the press-fitting process, the housing 200 is limited against rotation by the first anti-rotation limit block 234 extending into the notch 201.

[0042] A profiling surface that adheres to the surface of the iron core 300 is provided on the surface of the first anti-rotation limit block 234 facing the iron core 300, so that during the press-fitting process, it can move downward along the surface of the iron core 300 and then smoothly extend into the notch 201. A pair of first anti-rotation limit blocks 234 are symmetrically distributed on both sides of the mounting cylinder column 231.

[0043] A vertical slide rail 235 is provided on the outer peripheral surface of the mounting cylinder column 231. The first anti-rotation limit block 234 is slidably arranged on the slide rail 235 through a slider and is held in an extended state by being downwardly urged by a first elastic member 236.

[0044] A first sensor 14 for detecting the in-place placement of the detection housing 200 and a second sensor 15 for detecting the in-place placement of the iron core 300 are further provided on the lower support assembly 1.

[0045] Since a magnetic sheet is provided in the iron core 300 and the magnetic sheet is inserted into the accommodation groove of the iron core body by means of gluing, in order to prevent the magnetic sheet from falling out of the accommodation groove during subsequent assembly, in this embodiment, while pressing and installing the iron core 300 and the housing 200, the function of riveting the end face of the iron core is also realized. By riveting and piercing the positions of the two axial end faces of the iron core close to the accommodation groove, the inner wall surface of the accommodation groove is extruded to bulge inwards, forming an axial limit on the magnetic sheet, thereby realizing the anti-falling function. Specifically,

[0046] A first floating pressing plate 123 that elastically floats up and down is provided on the base 121. The first floating pressing plate 123 is arranged on the base 121 through a first limit screw 124. By adjusting the screwing depth of the first limit screw 124, the up and down floating amount of the first floating pressing plate 123 relative to the base 121 can be adjusted. A plurality of second elastic members 125 that upwardly support the first floating pressing plate 123 are arranged between the first floating pressing plate 123 and the base 121. A plurality of first riveting ejector pins 126 corresponding to the positions of the magnetic sheets in the iron core 300 are provided on the base 121. The first riveting ejector pins 126 pass through the first floating pressing plate 123. In the case where there is no external acting force on the lower support assembly 1, the first riveting ejector pins 126 are embedded in the first floating pressing plate 123. When the iron core 300 is placed on the first floating pressing plate 123 and receives a downward pressing force, the first floating pressing plate 123 is pressed close to the base 121, and at the same time, the first riveting ejector pins 126 extend out of the surface of the first floating pressing plate 123 to rivet the bottom axial end face of the iron core 300.

[0047] Similarly, the pressing mechanism 2 is also equipped with a riveting function. A second floating pressing plate 237 is arranged on the lower surface of the upper pressing plate 232 to float up and down. The second floating pressing plate 237 is arranged below the upper pressing plate 232 through a second limit screw 238, and the up-and-down floating amount of the second floating pressing plate 237 relative to the upper pressing plate 232 can be adjusted by adjusting the screwing depth of the second limit screw 238. A number of third elastic members 239 for pressing the second floating pressing plate 237 downward are arranged between the second floating pressing plate 237 and the upper pressing plate 232. A number of second riveting thimbles 2310 corresponding to the positions of the magnetic sheets in the iron core 300 are also arranged on the upper pressing plate 232. The second riveting thimbles 2310 pass through the second floating pressing plate 237. When the pressing mechanism 2 is not subjected to axial pressure, the second riveting thimbles 2310 are embedded in the second floating pressing plate 237. When the pressing mechanism 2 operates for pressing, the second floating pressing plate 237 squeezes the top shaft end face of the iron core 300, and then the upper pressing plate 232 continues to descend relative to the second floating pressing plate 237. The distance between the upper pressing plate 232 and the second floating pressing plate 237 is reduced to be tightly attached to each other. After the iron core 300 is pressed in place, the second riveting thimbles 2310 penetrate through the second floating pressing plate 237 and pierce into the top shaft end face of the iron core 300 to achieve riveting.

[0048] In addition, in order to ensure the accurate assembly angle between the iron core 300 and the housing 200, a second anti-rotation limit block 127 for angle positioning in cooperation with the groove on the inner hole wall of the iron core 300 is arranged on the first positioning block 122.

[0049] The housing handling mechanism 3 includes a second driving member 31, a first support plate 32 driven by the second driving member 31 to move horizontally, a second air cylinder 33 arranged on the first support plate 32, a third air cylinder 34 driven by the second air cylinder 33 to move up and down, a fourth air cylinder 35 driven by the third air cylinder 34 to rotate around a horizontal axis, and a first jaw 36 driven by the fourth air cylinder 35 to open or clamp. The cooperation between the second driving member 31 and the second air cylinder 33 mainly realizes the handling of the housing 200 from the secondary positioning mechanism 6 to the lower support assembly 1, and the third air cylinder 34 is mainly used to realize the flipping of the housing 200. Since the housing 200 is a thin-walled cylindrical structure, to achieve the positioning of the circumferential angle, only two notches 201 on the thin-walled cylinder can be relied on. Therefore, a third positioning block 61 is arranged on the secondary positioning mechanism 6, and a third anti-rotation limit block 62 corresponding to the position of the notch 201 is arranged on the third positioning block 61. After the housing 200 is taken out from the feeding mechanism, it needs to be first placed on the secondary positioning mechanism 6 for angle positioning, and then the housing handling mechanism 3 can handle it to the lower support assembly 1 for pressing operation. The third positioning block 61 is also driven by a fifth air cylinder 63 to move up and down.

[0050] During press-fitting, in order to ensure that the housing 200 does not deviate or rotate, it is necessary to utilize the notch 201 on the housing 200 to achieve angular positioning again. If an angular positioning structure is directly designed on the base 121, it may affect the pressing-in of the iron core 300. Therefore, in this embodiment, the anti-rotation limit of the housing 200 is designed on the press-fitting mechanism 2, and the 180° flipping action of the housing 200 is achieved in cooperation with the third cylinder 34 in the housing handling mechanism 3, so that the notch 201 in the housing 200 faces upward, and the first anti-rotation limit block 234 on the press-fitting mechanism 2 is inserted into the notch 210 during the press-fitting process to achieve angular positioning.

[0051] The iron core handling mechanism 4 includes a third driving member 41, a sixth cylinder 42 driven by the third driving member 41 to perform horizontal linear motion, a seventh cylinder 43 driven by the sixth cylinder 42 to perform vertical motion, and a second jaw 44 driven by the seventh cylinder 43 to perform opening or clamping motion.

[0052] The oiling mechanism 5 includes an oil injection assembly 51 and a roller brush assembly 52 arranged above the transfer path of the housing handling mechanism 3, and the oil injection assembly 51 and the roller brush assembly 52 are arranged opposite to each other. The oil injection assembly 51 includes a fourth driving member 511, a second support plate 512 driven by the fourth driving member 511 to perform vertical motion, an eighth cylinder 513 fixed on the second support plate 512, a third support plate 514 driven by the eighth cylinder 513 to perform horizontal movement, an oil injection valve 515 fixed on the third support plate 514, and a brush plate 516. The roller brush assembly 52 includes a fifth driving member 521, a fourth support plate 522 driven by the fifth driving member 521 to perform vertical motion, a sixth driving member 523 fixed on the fourth support plate 522, and a sponge roller brush 524 driven by the sixth driving member 523 to perform rotational motion. When oiling the inner wall surface of the housing 200, the housing handling mechanism 3 clamps the housing 200 and moves it below the oiling mechanism 5. The eighth cylinder 513 drives the third support plate 514 to extend forward, and the oil injection valve 515 injects a set amount of grease onto the surface of the sponge roller brush 524 in advance. At the same time, through the cooperation of the brush plate 516 and the rotational motion of the sponge roller brush 524, the grease is evenly smeared on the sponge roller brush 524. After the housing 200 is in place, the sponge roller brush 524 extends into the housing 200 and rotates to evenly smear the grease on the inner wall surface of the housing 200. By smearing grease on the inner wall surface of the housing 200, the friction force during the assembly of the housing 200 and the iron core 300 can be reduced, and the smoothness of press-fitting can be improved.

[0053] The present embodiment is a fully automatic press-fitting device 100, and the working process is as follows: the shell 200 is grabbed onto the secondary positioning mechanism 6 for secondary positioning to correct its angular position; then the shell conveying mechanism 3 takes the shell 200 out of the secondary positioning mechanism 6 and flips it 180° and moves it to the bottom of the oiling mechanism 5, and the sponge roller brush 524 descends and extends into the shell 200 to oil the inner wall surface of the shell 200; then the shell 200 is conveyed to the lower support assembly 1 and placed in the limiting support groove 111 of the fixed support seat 11; after the shell 200 is put into place, the movable support seat 12 rises upward, and the iron core conveying mechanism 4 clamps the iron core 300 from the carrier of the conveyor line and places it on the movable support seat 12, specifically on the first floating pressure plate 123, and through the first positioning block 122 A pair of second stop blocks 127 realizes angular positioning; after the iron core 300 is placed in place, the pressing mechanism 2 starts to move, the installation column 231 descends, and the two first stop blocks 234 first approach the outer circumferential surface of the iron core 300 and move downward along the outer circumferential surface of the iron core 300, while slowly extending into the notch 201; then the second floating pressure plate 237 begins to elastically contact the top of the iron core 300, and the installation column 231 continues to descend, slowly pressing the iron core 300 into the shell 200 through the second floating pressure plate 237, and at the same time, the movable support seat 12 moves downward synchronously; when the iron core 300 cannot move further downward after being pressed into place, the first riveting ejector pin 126 and the second riveting ejector pin 2310 act on the two axial end faces of the iron core 300 to realize riveting and complete the press fitting.
