Description

Technical Field

[0001] The present application belongs to the field of motor assembly, and more specifically, relates to a rotor end cover bearing assembly machine. Background Art

[0002] The motor includes a rotor and an end cover. When assembling the motor, the bearing needs to be installed on the end cover to form a first component, and then the rotor needs to be installed on the first component to form a second component.

[0003] Referring to Chinese patent CN209767340U, the conveyor assembly is capable of conveying the tooling base to the front cover bearing assembly and the rotor bearing assembly. During operation, the tooling base is clamped with the front cover, and the conveyor assembly conveys the front cover to the front cover bearing assembly. The bearing is then installed on the front cover via the front cover bearing assembly, forming the first assembly. The conveyor assembly then conveys the front cover with the bearing installed to the rotor bearing assembly. The rotor is then inserted into the bearing on the front cover via the rotor bearing assembly, forming the second assembly.

[0004] However, in the prior art rotor end cover bearing assembly machine, the bearing is easily deformed during the process of press-fitting the bearing onto the end cover, resulting in a low yield rate. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a rotor end cover bearing assembly machine to solve the technical problem that the yield rate of the rotor end cover bearing assembly machine in the prior art needs to be improved.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of the present application are: A rotor cover bearing assembly machine is provided, comprising: The conveying mechanism includes a first conveying driving member and a first slide extending along a first direction; The tooling module includes a base, a positioning seat, a first elastic member and a support column, the positioning seat is used for positioning and installing the end cover, the positioning seat has a first mounting hole corresponding to the axial hole of the end cover, the support column is slidably installed in the first mounting hole along the vertical direction, the first elastic member is elastically compressed and arranged between the support column and the positioning seat, the positioning seat is slidably installed in the base along the vertical direction, the opposite sides of the base in the second direction are limited to the first slideway, and slide along the first direction under the drive of the first conveying drive member; the first direction, the second direction and the vertical direction are perpendicular to each other; The first press-fitting mechanism includes a first press-fitting bracket, a first press-fitting driver, and a first press-fitting assembly. The first press-fitting bracket is located next to the first slideway. The first press-fitting driver is installed on the first press-fitting bracket and drives the first press-fitting assembly to move up and down. The first press-fitting assembly is used to pick up the bearing component. The first press-fitting assembly, driven by the first press-fitting driver, presses the bearing component into the bearing hole. The second press-fitting mechanism is spaced apart from the first press-fitting mechanism along the first direction. The second press-fitting mechanism picks up the rotor assembly and press-fits the rotating shaft of the rotor assembly onto the inner ring of the bearing component.

[0007] The rotor end cover bearing assembly machine provided by the embodiment of the present application has at least the following beneficial effects: the end cover member is positioned and installed on the positioning seat of the tooling module, and the tooling module is initially located below the first press-fitting component or slides to the bottom of the first press-fitting component along the first direction under the drive of the first conveying drive member, the first press-fitting component picks up the bearing member, and the first press-fitting drive member drives the first press-fitting component to move downward in the vertical direction. When the bearing member is pressed into the bearing hole of the end cover member with an interference fit, the positioning seat slides downward, and the positioning seat and the end cover member positioned and installed on the positioning seat have floating properties to avoid rigid stamping. The support column exposes the first mounting hole, and the inner ring of the bearing member is elastically supported by the elastic force of the first elastic member to avoid force on the outer ring and offset the rigid squeezing of the inner ring by the pressing force. At the same time, it gradually moves downward elastically without hindering the pressing of the bearing member. After the bearing component is assembled, the first pressing mechanism is reset, and the tooling module slides along the first direction to the second pressing mechanism under the drive of the first conveying drive component. The second pressing mechanism picks up the rotor assembly and presses the rotating shaft of the rotor assembly onto the inner ring of the bearing component. Since the bearing component does not deform, the coaxiality of the bearing component and the rotating shaft is high, which improves the yield rate of the assembled product.

[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0012] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0013] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, the Y-axis, and the Z-axis. The direction along the X-axis is the longitudinal direction, the direction along the Y-axis is the transverse direction, and the direction along the Z-axis is the vertical direction. The X-axis and Y-axis are two mutually perpendicular coordinate axes in the same horizontal plane, and the Z-axis is the vertical coordinate axis. The X-axis, Y-axis, and Z-axis are located in three mutually perpendicular planes in space: the XY plane, the YZ plane, and the XZ plane. The XY plane is a horizontal plane, the XZ plane and the YZ plane are both vertical planes, and the XZ plane is perpendicular to the YZ plane. The three axes in space are the X-axis, Y-axis, and Z-axis. Movement along these three axes in space refers to movement along the three mutually perpendicular axes in space, specifically movement along the X-axis, Y-axis, and Z-axis in space. Planar movement, on the other hand, refers to movement in the XY plane.

[0014] See also Figure 1 The end cover 20 has a shaft hole 21 for the rotating shaft 31 of the rotor assembly 30 to pass through and a bearing hole 22 for assembling the bearing member 10. The bearing hole 22 is connected to the shaft hole 21, and the bearing hole 22 is located on the inner side of the shaft hole 21.

[0015] See also Figure 2 The rotor cover bearing assembly machine provided in the embodiment of the present application includes a conveying mechanism 100, a tooling module 200, a first press-fitting mechanism 300 and a second press-fitting mechanism 400. Figure 4 The conveying mechanism 100 includes a first conveying driving member 110 and a first slideway 120 extending along a first direction X. Figure 3 The tooling module 200 includes a base 210, a positioning seat 220, a first elastic member 230, and a support column 240. The positioning seat 220 is used to position and install the end cover 20. The positioning seat 220 has a first mounting hole 221 corresponding to the axial hole 21 of the end cover 20. The support column 240 is slidably mounted in the first mounting hole 221 along the vertical direction Z. The first elastic member 230 is elastically compressed and disposed between the support column 240 and the positioning seat 220. The positioning seat 220 is slidably mounted on the base 210 along the vertical direction Z. The base 210 is constrained on opposite sides of the first slideway 120 in the second direction Y and slides in the first direction X under the drive of the first conveyor drive member 110. The first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other.

[0016] See also Figure 5 and Figure 6 The first press-fitting mechanism 300 includes a first press-fitting bracket 310, a first press-fitting driver 320, and a first press-fitting assembly 330. The first press-fitting bracket 310 is located next to the first slideway 120. The first press-fitting driver 320 is installed on the first press-fitting bracket 310 and drives the first press-fitting assembly 330 to move up and down. The first press-fitting assembly 330 is used to pick up the bearing component 10. Under the drive of the first press-fitting driver 320, the first press-fitting assembly 330 presses the bearing component 10 into the bearing hole 22. Please return to see Figure 2 The second press-fitting mechanism 400 and the first press-fitting mechanism 300 are spaced apart along the first direction X. The second press-fitting mechanism 400 picks up the rotor assembly 30 and press-fits the rotating shaft 31 of the rotor assembly 30 onto the inner ring of the bearing 10 .

[0017] In this embodiment, the end cover 20 is positioned and installed on the positioning seat 220 of the tooling module 200. The tooling module 200 is initially located below the first press-fitting component 330 or slides to the bottom of the first press-fitting component 330 along the first direction X under the drive of the first conveying drive member 110. The first press-fitting component 330 picks up the bearing component 10, and the first press-fitting drive member 320 drives the first press-fitting component 330 to move downward along the vertical direction Z. When the bearing component 10 is pressed into the bearing hole 22 of the end cover 20 with an interference fit, the end cover 20 and the positioning seat 220 are driven to move vertically downward relative to the base 210, with a downward floating amount to avoid rigid stamping. The support column 240 exposes the first mounting hole 221, and uses the elastic force of the first elastic member 230 to elastically support the inner ring of the bearing component 10, avoid the outer ring from being subjected to force, and offset the rigid extrusion of the inner ring by the press-fitting force, while gradually moving downward elastically without hindering the press-fitting of the bearing component 10. After the bearing component 10 is assembled, the first pressing mechanism 300 is reset, and the tooling module 200 slides along the first direction X to the second pressing mechanism 400 under the drive of the first conveying drive component 110. The second pressing mechanism 400 picks up the rotor assembly 30 and presses the rotating shaft 31 of the rotor assembly 30 onto the inner ring of the bearing component 10. Since the bearing component 10 does not deform and has a high coaxiality with the rotating shaft 31, the yield rate of the assembled product is improved.

[0018] In some embodiments, combined Figure 3 The tooling module 200 further includes a second elastic member 250, which is disposed between the base 210 and the positioning seat 220 to provide an upward elastic force to the positioning seat 220. The second elastic member 250 absorbs part of the pressure by deformation, allowing the positioning seat 220 to be vertically elastically slidably mounted on the base 210, thereby preventing rigid impact from causing damage to the end cover 20, the positioning seat 220, or the base 210. The second elastic member 250 then transmits the pressure to the base 210 and the first slideway 120, preventing the end cover 20 and the tooling module 200 from being deformed by force, thereby achieving position limitation in the vertical direction Z. Moreover, after the press-fitting is completed, the second elastic member 250 drives the positioning seat 220 to automatically reset.

[0019] Specifically, there are multiple second elastic members 250, and the multiple second elastic members 250 are evenly distributed around the first mounting hole 221, so that the positioning seat 220 is evenly forced to move downward, preventing tilting or offset due to uneven force, ensuring that the end cover member 20 is always in a horizontal state, ensuring the coaxiality of the bearing member 10 during press installation, and further reducing the risk of deformation of the bearing member 10 due to tilting force.

[0020] Specifically, the elastic coefficient of the second elastic member 250 is smaller than the elastic coefficient of the first elastic member 230. Due to the smaller elastic coefficient of the second elastic member 250, in the initial stage of press-fitting, the positioning seat 220 and the end cover 20 float downward as a whole, and the downward movement of the support column 240 is smaller than the downward movement of the positioning seat 220, thereby providing a continuous and stable elastic tightening force for the inner ring of the bearing member 10.

[0021] In some embodiments, combined Figure 3 and Figure 6 The tooling module 200 also includes a first guide member 260. One end of the first guide member 260 is mounted on one of the base 210 and the positioning seat 220, and the other end of the first guide member 260 is disposed through the other of the two, with a gap in the vertical direction Z. The first guide member 260 ensures that the positioning seat 220 floats relative to the base 210 in the vertical direction Z. Without a guide, the mating surfaces of the base 210 and the positioning seat 220 may wear due to uneven friction during long-term reciprocating motion, resulting in an increased gap and further exacerbated misalignment.

[0022] Optionally, the first guide member 260 is fixedly mounted on the base 210, and the positioning seat 220 has a first guide hole for clearance fit of the first guide member 260. A first stop block that cannot pass through the first guide hole is provided at the upper end of the first guide member 260, limiting the relative upward movement range of the positioning seat 220.

[0023] Optionally, there are two first guide members 260, located on the same diameter centered on the first mounting hole 221. There are four second elastic members 250, distributed circumferentially with equal intervals about the first mounting hole 221. The first guide members 260 and the second elastic members 250 are located on the same circular trajectory, and the points of application of the elastic force and the guide constraint are on the same circumference, resulting in a more coordinated force transmission path and reducing the additional torque caused by the difference in the lever arm. The four second elastic members 250 are symmetrically distributed about the diameter of the two first guide members 260. This symmetrical distribution ensures that the elastic force of the positioning seat 220 is equal in any radial direction.

[0024] In some embodiments, combined Figure 3 and Figure 6 The first elastic member 230 is sleeved with the support column 240. The support column 240 strictly limits and positions the deformation direction of the first elastic member 230, ensuring that the elastic force of the first elastic member 230 always acts on the support column 240 along the vertical direction Z.

[0025] In some embodiments, combined Figure 6 A first step is provided on the inner wall of the first mounting hole 221, and a second step is provided on the support column 240. The first step and the second step are spaced apart up and down, and both ends of the first elastic member 230 abut against the first step and the second step respectively.

[0026] In some embodiments, combined Figure 3 The positioning seat 220 is provided with a positioning pin 213, and the end cover 20 has a positioning hole 23. The positioning pin 213 is positioned and embedded in the positioning hole 23, so that the end cover 20 is positioned and installed on the positioning seat 220. Optionally, the number of positioning pins 213 is two, and the angle formed by the two positioning pins 213 with the first mounting hole 221 as the center is not 180°, that is, they are asymmetrically distributed, ensuring that the end cover 20 is positioned and assembled on the positioning seat 220 at a unique angle.

[0027] In some embodiments, combined Figure 2 and Figure 4 The conveying mechanism 100 includes a pressing drive member 181 and a pressing plate 182. The pressing drive member 181 is mounted on the first slideway 120 and corresponds to the position of the second press-fitting mechanism 400. The pressing drive member 181 drives the pressing plate 182 to move up and down to press and fix the end cap member 20 that has reached the second press-fitting mechanism 400 onto the positioning seat 220. The downward pressure of the pressing plate 182 can directly offset the upward reaction force, so that the positioning seat 220 and the first elastic member 230 remain relatively stationary during the press-fitting process.

[0028] Specifically, there are two pressing driving members 181 and two pressing plates 182 , and the two pressing plates 182 are respectively pressed on two opposite sides of the end cover 20 in the length direction to ensure that the end cover 20 is evenly stressed and does not deform.

[0029] In some embodiments, combined Figure 2 and Figure 3 The conveying mechanism 100 also includes a first positioning and driving member 131. The output end of the first positioning and driving member 131 abuts against the base 210 located on the first slideway 120 along the second direction Y, thereby clamping and securing the base 210 to the first pressing mechanism 300. When the tooling module 200 reaches the first pressing mechanism 300, the first positioning and driving member 131 presses and secures the tooling module 200, facilitating the pressing operation. Otherwise, if the base 210 is in a floating state, it may tilt or wobble slightly due to uneven force.

[0030] Optionally, the base 210 has a first positioning notch 211, and the output end of the first positioning drive member 131 is embedded in the first positioning notch 211 to achieve mechanical locking, thereby limiting the freedom of movement of the base 210 along the first direction X, avoiding the base 210 from shaking along the first direction X during positioning, and improving positioning stability.

[0031] In some embodiments, combined Figure 2 and Figure 3The conveying mechanism 100 also includes a second positioning and driving member 132. The output end of the second positioning and driving member 132 abuts against the base 210 located on the first slideway 120 along the second direction Y, thereby clamping and securing the base 210 to the second pressing mechanism 400. When the tooling module 200 reaches the second pressing mechanism 400, the second positioning and driving member 132 presses and secures the tooling module 200, facilitating the pressing operation. Otherwise, if the base 210 is in a floating state, it may tilt or wobble slightly due to uneven force.

[0032] Optionally, the base 210 has a first positioning notch 211, and the output end of the second positioning drive member 132 is embedded in the first positioning notch 211 to achieve mechanical locking, thereby limiting the freedom of movement of the base 210 along the first direction X, avoiding the base 210 from shaking along the first direction X during positioning, and improving positioning stability.

[0033] In some embodiments, combined Figure 2 and Figure 4 The conveying mechanism 100 also includes a second conveying drive member 140, a third conveying drive member 150, a fourth conveying drive member 160 and a second slide 170. The second slide 170 and the first slide 120 are arranged parallel to each other. The fourth conveying drive member 160 drives the tooling module 200 located on the second slide 170 to slide along the first direction X. The sliding directions of the tooling module 200 on the first slide 120 and the second slide 170 are opposite. The second conveying drive member 140 drives the tooling module 200 located at the end of the first slide 120 to be pushed toward the head end of the second slide 170. The third conveying drive member 150 drives the tooling module 200 located at the end of the second slide 170 to be pushed toward the head end of the first slide 120. Based on this, the tooling module 200 slides from the head end to the end of the first slide 120 along the first direction X under the drive of the first conveying drive member 110, and moves from the end of the first slide 120 to the head end of the second slide 170 under the drive of the second conveying drive member 140. Under the drive of the fourth conveying drive member 160, it slides from the head end to the end of the second slide 170 along the first direction X, and moves from the end of the second slide 170 to the head end of the first slide 120 under the drive of the third conveying drive member 150, thereby realizing the recycling and reuse of the tooling module 200, reducing costs and ensuring continuous production.

[0034] Optionally, the second conveying driving member 140 drives the tooling module 200 to slide along the second direction Y. The third conveying driving member 150 drives the tooling module 200 to slide along the second direction Y. Figure 4In the example shown, the tooling module 200 slides in the positive direction of the first direction X under the drive of the first conveying drive member 110, slides in the positive direction of the second direction Y under the drive of the second conveying drive member 140, slides in the negative direction of the first direction X under the drive of the fourth conveying drive member 160, and slides in the negative direction of the second direction Y under the drive of the third conveying drive member 150.

[0035] Optionally, a third conveyor drive 150 is mounted on top of the first conveyor drive 110. The output end of the third conveyor drive 150 pushes the tooling module 200 from the side of the tooling module 200 away from the first slideway 120. Specifically, the tooling module 200 has a second positioning notch 212. The first positioning notch 211 and the second positioning notch 212 are located on opposite sides of the tooling module 200 in the second direction Y. The output end of the third conveyor drive 150 is embedded in the second positioning notch 212 to push the tooling module 200.

[0036] In some embodiments, combined Figure 2 and Figure 3 The top of the first slide 120 is provided with a first stop bar 121 and a second stop bar 122 spaced apart along the second direction Y. The first stop bar 121 and the second stop bar 122 are respectively used to abut the top surface of the base 210. The first stop bar 121 is located closer to the second slide 170 than the second stop bar 122. A circulation notch 123 is provided at each end of the first stop bar 121 to allow the tooling module 200 to enter and exit the first slide 120 through the circulation notch 123. The first and second stop bars 121, 122 prevent the tooling module 200 from bouncing up and down and shifting left and right during transportation, ensuring sliding accuracy. The design of the circulation notch 123 ensures a smooth circulation path and avoids production line stalls caused by structural interference.

[0037] In some embodiments, combined Figure 2 、 Figure 5 and Figure 6 The first press-fitting assembly 330 includes a first seat body 331 and a first positioning column 332. The first positioning column 332 is arranged on the first seat body 331. The first positioning column 332 is detachably embedded in the inner ring of the bearing component 10. The first positioning column 332 picks up the bearing component 10 and can be detachably separated from the bearing component 10 after press-fitting.

[0038] Specifically, the first seat body 331 abuts against the upper end surface of the bearing component 10 to provide support for the bearing component 10 . The support area is large, thereby preventing the bearing component 10 from being suspended and deformed by force.

[0039] Specifically, the first positioning post 332 is embedded with a magnetic member 3321, which achieves a detachable connection with the bearing member 10 via the magnetic member 3321. After the bearing member 10 is press-fitted, the first press-fitting driver 320 drives the first positioning post 332 upward. Since the bearing member 10 is snapped into the bearing hole 22 of the end cover 20, the magnetic member 3321 naturally separates from the bearing member 10 during the upward movement, eliminating the need for additional assembly and disassembly operations. This prevents the bearing member 10 from being dislodged or the inner ring from being deformed due to interference fit.

[0040] Optionally, the magnetic member 3321 is an electromagnet or a permanent magnet. The magnetism of the electromagnet is controllable. When the magnetic member 3321 needs to be separated from the bearing member 10, the current to the electromagnet is cut off and the magnetism disappears, achieving resistance-free separation and preventing force on the inner ring. Optionally, there are multiple magnetic members 3321, and the multiple magnetic members 3321 are distributed circumferentially around the first positioning post 332. The multiple magnetic members 3321 are distributed circumferentially to form a uniform annular magnetic field. The magnetic force acts evenly on the inner ring circumference of the bearing member 10. The circumferential distribution of the magnetic members 3321 creates a symmetrical constraint, ensuring that the bearing member 10 remains coaxial with the first positioning post 332.

[0041] Specifically, combined Figure 6 、 Figure 7 and Figure 8 The first seat 331 is provided with a first annular step 3311, which abuts against the outer ring of the bearing component 10 to prevent deformation of the outer ring of the bearing component 10. The outer ring of the bearing component 10 is the core component that has an interference fit with the end cover bearing hole 22. If uneven force is applied or local pressure is excessive, it is prone to plastic deformation, resulting in an abnormal clearance with the end cover 20. The first annular step 3311, by contacting the annular surface of the outer ring, evenly distributes the press-fitting force on the end face of the outer ring, avoiding local stress concentration, preventing radial deformation of the outer ring due to unbalanced loads, and ensuring the precision of its fit with the bearing hole 22.

[0042] Specifically, a gap exists between the first seat 331 and the inner ring of the bearing component 10. The inner ring is supported by the support column 240 and its flexible tightening force prevents relative compression with the outer ring, thereby protecting the precision of the fit between the rolling elements and the raceway within the bearing component 10. If there were no gap between the inner ring and the first seat 331, the inner ring might be pushed upward by the support column 240 during press-fitting and floating due to the stationary first seat 331, resulting in axial misalignment between the inner ring and the outer ring.

[0043] In some embodiments, combined Figure 6 、 Figure 8 and Figure 9The first press-fit mechanism 300 includes a second positioning post 340, which is mounted on the first press-fit bracket 310 and located below the first slideway 120. The first positioning post 332 and the second positioning post 340 are coaxially arranged. When the tooling module 200 is in place, the bearing hole 22 and the second positioning post 340 are coaxially arranged, and the bearing component 10 and the first positioning post 332 are coaxially arranged, ensuring the coaxiality of the bearing component 10 and the bearing hole 22 during assembly.

[0044] Specifically, the first slideway 120 has a first support hole 124, and the second positioning post 340 is embedded in the first support hole 124. The second positioning post 340 has a first avoidance hole 341. The upper end diameter of the first avoidance hole 341 is larger than the lower end diameter of the support post 240. This prevents the second positioning post 340 from abutting the support post 240 and interfering with the elastic floating of the support post 240.

[0045] In some embodiments, combined Figure 6 、 Figure 8 and Figure 9 The first press-fit assembly 330 further includes a second base 335, a connecting post 336, and a first support ring 3371. The second base 335 is connected to the output end of the first press-fit driver 320. The second base 335 is fixedly mounted on the first base 331. The connecting post 336 is fixedly mounted on the second base 335 and extends vertically downward. The first support ring 3371 is mounted on the lower end of the connecting post 336. The first support ring 3371 is used to press the top of the end cap 20. The first support ring 3371 is used to press the top of the end cap 20 to stabilize the position of the end cap 20 and prevent the end cap 20 from shaking due to force during press-fitting.

[0046] Specifically, the first press-fit assembly 330 further includes a first elastic sleeve 333. A first support ring 3371 is vertically slidably mounted on the connecting post 336. The first elastic sleeve 333 is sleeved onto the connecting post 336. The first elastic sleeve 333 is compressible at the moment of press-fit contact, buffering the impact speed and force, thereby preventing surface indentations or cracks on the end cap 20.

[0047] Specifically, the first press-fit assembly 330 further includes a second support ring 3372, which is embedded in the bottom of the first support ring 3371 and is used to press the top of the end cap 20. The second support ring 3372 is a plastic component. Compared to metal components, plastic components are less rigid and more elastic. When the second support ring 3372 presses the end cap 20, it can reduce the contact stress between the two components.

[0048] In some embodiments, a first positioning post 332 is vertically slidably disposed within the first base 331. The first press-fit assembly 330 further includes a post driver 334 mounted on the second base 335. The post driver 334 drives the vertical movement of the first positioning post 332. Therefore, when the first press-fit assembly 330 descends until the bearing component 10 abuts the opening of the bearing hole 22, the first positioning post 332 is inserted into the bearing hole 22, utilizing its axis reference to ensure the coaxiality of the bearing component 10 and the bearing hole 22, completing alignment. The post driver 334 then drives the first positioning post 332 upward, preventing stress on the inner race during press-fitting.

[0049] Specifically, the first press-fit assembly 330 also includes an adapter seat 338 and a first shell 339. One end of the first shell 339 is connected to the second seat body 335, and the other end of the first shell 339 is connected to the adapter seat 338. The connecting column 336 is installed on the adapter seat 338, that is, the connecting column 336 is indirectly installed on the second seat body 335 through the adapter seat 338 and the first shell 339. The cavity enclosed by the first shell 339 is used to protect the electrical connection of the column drive 334, and the cavity is conducive to reducing weight.

[0050] In one embodiment, combined Figure 2 The rotor end cover bearing assembly machine also includes a dust collection component 350. The dust collection component 350 is located between the first press-fitting mechanism 300 and the second press-fitting mechanism 400. The dust collection component 350 is installed on the first press-fitting bracket 310. The dust collection component 350 is used to cover the tooling module 200 located downstream of the first press-fitting mechanism 300 to complete the dust collection operation. The first is to remove impurities generated after the press-fitting of the first press-fitting mechanism 300, and the second is to provide a clean tooling module 200 for the press-fitting of the second press-fitting mechanism 400.

[0051] In some embodiments, combined Figure 2 、 Figure 10 and Figure 11 The second press-fitting mechanism 400 includes a second press-fitting bracket 410, a second press-fitting driver 420, and a lifting driver 430. The support column 240 has a second avoidance hole 242. The output end of the lifting driver 430 is connected to a first lifting shaft 431, which is lifted and lowered through the second avoidance hole 242. The second press-fitting driver 420 is mounted on the second press-fitting bracket 410 and is located above the first slideway 120. The output end of the second press-fitting driver 420 is connected to a second lifting shaft 421, and the second lifting shaft 421 and the first lifting shaft 431 are coaxially arranged.

[0052] The rotor assembly 30 is loaded automatically by a robot or manually onto the second press-fitting mechanism 400. The ends of the rotor assembly 30's rotating shaft 31 are clamped by the first and second lifting shafts 431, 421, respectively. The first and second lifting shafts 431, 421 then descend synchronously, and the rotor assembly 30 is subsequently lowered and press-fitted into the inner ring of the bearing 10 and the movable through-hole 21. During the descent, the rotating shaft 31 is supported at both ends to prevent wobbling while suspended. The coaxial arrangement of the second and first lifting shafts 421, 431, improves the coaxiality between the rotor assembly 30 and the end cap 20, preventing motor eccentricity, centrifugal force, vibration, and noise during operation caused by insufficient coaxiality.

[0053] In some embodiments, the end of the first lifting shaft 431 has a first cone, which is used to be embedded in the end of the rotating shaft 31. The first cone forms a linear contact guide with the concave hole at the end of the rotating shaft 31, further preventing axial movement or circumferential swing of the end of the rotating shaft 31.

[0054] In one embodiment, combined Figure 12 and Figure 13 The second lifting shaft 421 has a second tapered body 422 at its end. The second tapered body 422 is embedded in the end of the rotating shaft 31 to improve the precise positioning between the second lifting shaft 421 and the rotating shaft 31. The second tapered body 422 forms a linear contact guide with the recessed hole at the end of the rotating shaft 31, further preventing axial movement or circumferential swing of the end of the rotating shaft 31.

[0055] In one embodiment, the second lifting shaft 421 is elastically mounted on the output end of the second press-fit drive 420. When the second lifting shaft 421 contacts the rotating shaft 31, it can absorb the initial impact energy through the elastic mounting, thereby avoiding damage to the end face of the rotating shaft 31 or positional displacement caused by the rigid mounting. The elastic mounting ensures that the second lifting shaft 421 always maintains stable contact with the top of the rotating shaft 31, continuously provides axial support force for the rotating shaft 31, and prevents the top of the rotating shaft 31 from separating from the second lifting shaft 421. The elastic mounting ensures that the second lifting shaft 421 always maintains contact with the top of the rotating shaft 31, even when the speed of the second press-fit drive 420 fluctuates or vibrates, it can also avoid shaking of the rotating shaft 31 caused by momentary separation.

[0056] In one embodiment, the second press-fitting mechanism 400 further includes a third elastic member 440, a third base 461, and a fourth base 462. The fourth base 462 is mounted at the output end of the second press-fitting driver 420, and the third base 461 is mounted at the lower end of the fourth base 462. The third elastic member 440 is housed within the fourth base 462. One end of the third elastic member 440 abuts against the inner wall of the fourth base 462, and the other end abuts against the second lifting shaft 421. The distal end of the second lifting shaft 421 elastically extends vertically from the lower surface of the third base 461 to abut against the rotating shaft 31. The third elastic member 440 absorbs the initial impact force by deforming itself, allowing the second lifting shaft 421 to flexibly conform to the rotating shaft 31. The structural design of the third base 461 and the fourth base 462 provides dual guidance for the elastic compression direction of the second lifting shaft 421, thereby improving movement accuracy. The fourth base body 462 has a blind hole, one end of the third elastic member 440 rests against the bottom of the blind hole, and the other end is sleeved on the second lifting shaft 421. The third base body 461 has a through hole for the second lifting shaft 421 to expose the lower end surface. The second lifting shaft 421 has a step, which rests against the upper end of the through hole to prevent the second lifting shaft 421 from falling.

[0057] Optionally, the second press-fitting mechanism 400 also includes a second shell 463, which includes a third seat body 461 and a fourth seat body 462, thereby improving the connection strength between the two, indirectly enhancing the structural stability of the entire elastic mounting assembly, and avoiding slight deformation of the third seat body 461 caused by long-term press-fitting reaction force.

[0058] In some embodiments, the first slide 120 has a second support hole 125, and the second press-fitting mechanism 400 further includes a third positioning post 450. The third positioning post 450 is mounted on the second press-fitting bracket 410 and is located below the first slide 120. The third positioning post 450 is disposed within the second support hole 125. The third positioning post 450 has a third avoidance hole 451, which is coaxially arranged with the first lifting shaft 431. The third avoidance hole 451 provides protection and guidance for the lifting movement of the first lifting shaft 431. For the slender first lifting shaft 431, the wall of the third avoidance hole 451 can provide radial support, reduce bending deformation when subjected to force, and ensure the stability of the lifting movement.

[0059] In some embodiments, combined Figure 2 The rotor end cap bearing assembly machine includes a workbench 610, and the conveying mechanism 100, the first press-fitting mechanism 300, and the second press-fitting mechanism 400 are installed on the workbench 610. The workbench 610 provides a unified installation base and a horizontal reference.

[0060] Specifically, combined Figure 14The rotor end cover bearing assembly machine includes a working cover 620, which covers a conveying mechanism 100, a first pressing mechanism 300 and a second pressing mechanism 400, thereby preventing the pressing operation from being interfered with externally and providing support for the efficient, stable and safe operation of the rotor end cover bearing assembly machine.

[0061] Specifically, the rotor cap bearing assembly machine includes a controller mounted below a workbench 610. The conveying mechanism 100, the first press-fitting mechanism 300, and the second press-fitting mechanism 400 are located above the workbench 610. The workbench 610 serves as a physical partition, preventing the concentrated stacking of various components and achieving a separation between dynamic and static areas, making the overall structure of the equipment more compact.

[0062] In some embodiments, combined Figure 15 The rotor end cover bearing assembly machine also includes an end cover loading mechanism 510, which includes an end cover robot 511 and an end cover transfer assembly 512. The end cover robot 511 picks up a single end cover part 20 to the end cover transfer assembly 512 in sequence, and the end cover transfer assembly 512 transports the end cover part 20 in a straight line to the positioning seat 220 located on the first slide 120, thereby realizing automatic loading of the end cover part 20.

[0063] Specifically, the end cap feeding mechanism 510 includes an end cap material warehouse 513. The end cap material warehouse 513 centrally stores a certain number of end cap pieces 20, thereby ensuring the continuity and accuracy of the production line.

[0064] Specifically, the end cover transfer assembly 512 includes a first cover transfer assembly 514 and a second cover transfer assembly 515, both extending along the second direction Y. One end of the first cover transfer assembly 514 is within the operating range of the end cover robot 511, and the other end of the first cover transfer assembly 514 is docked with one end of the second cover transfer assembly 515. The second cover transfer mechanism clamps the end cover part 20 and loads it horizontally along the second direction Y to above the positioning seat 220 on the first slide 120. The two-stage design can flexibly adapt to the overall layout of the equipment, for example, it can be staggered with the loading path of the rotor assembly 30 in the height direction. Both sections of the cover transfer assemblies are transported along the second direction Y to avoid positioning errors caused by directional turning and reduce the occupied volume. The first cover transfer assembly 514 also plays the role of receiving and caching.

[0065] Specifically, the end cap material warehouse 513, the end cap robot 511, the first cap transfer assembly 514 and the second cap transfer assembly 515 are arranged in sequence along the second direction Y to realize the linear transmission of the end cap part 20 without unnecessary turns or intersections throughout the process. The linear arrangement layout can maximize the use of the space in the second direction Y. Figure 15 The red dotted line in FIG. 1 represents the conveying path of the end cover member 20 .

[0066] In some embodiments, combined Figure 15The rotor end cover bearing assembly machine also includes a bearing loading mechanism 520, which includes a bearing robot 521 and a bearing transfer assembly 522. The bearing robot 521 picks up individual bearing parts 10 in turn to the bearing transfer assembly 522, and the bearing transfer assembly 522 transports the bearing parts 10 in a straight line to the first press-fitting assembly 330, thereby realizing automated continuous loading.

[0067] Specifically, the bearing loading mechanism 520 includes a bearing warehouse 523 and a pushing assembly 524. The bearing warehouse 523 is used to store bearings, and the pushing assembly 524 is used to stack bearings and use gravity to push out the bearing parts 10 from the bottom in sequence. The bearing robot 521 clamps the pushed-out bearing parts 10 and places them on the bearing transfer robot. Compared with decentralized racks, the bearing warehouse 523 can store a large number of bearing parts 10 in a stacked manner, which can increase the storage capacity within a limited space. The pushing assembly 524 pushes out the bearing parts 10 in sequence from the bottom, and new bearing parts 10 can be added to the top at any time without stopping the machine for refilling, further improving the continuity of feeding. During the stacking storage and gravity pushing process of the pushing assembly 524, the bearing parts 10 only fall slowly in the guide groove of the pushing assembly 524, thereby protecting the precise surface and dimensional accuracy of the bearing parts 10 to the greatest extent.

[0068] Specifically, the bearing material warehouse 523 and the end cover material warehouse 513 are spaced apart along the first direction X and are located on the same side of the workbench 610, with a compact layout. The bearing material warehouse 523, the pusher assembly 524, the bearing robot 521 and the bearing transfer assembly 522 are spaced apart along the second direction Y, wherein the length direction of the pusher assembly 524 is consistent with the first direction X, and the conveying direction of the bearing transfer assembly 522 is consistent with the second direction Y. Figure 15 As shown, the green dotted line represents the transmission path of the bearing member 10.

[0069] In some embodiments, combined Figure 15 The rotor end cover bearing assembly machine also includes a rotor loading mechanism 530, which includes a rotor robot 531 and a rotor transfer assembly 532. The rotor robot 531 picks up a single rotor assembly 30 to the rotor transfer assembly 532 in turn, and the rotor transfer assembly 532 transports the rotor assembly 30 to the second pressing mechanism 400 to achieve efficient and continuous loading.

[0070] Specifically, the rotor loading mechanism 530 includes a code scanning component 533 and an outer diameter collection component 534. The rotor robot 531 clamps a single rotor assembly 30 from the outside and places it in the scanning component to scan the code. Then, the rotor assembly 30 is clamped to the outer diameter collection component 534, the outer diameter of the rotor assembly 30 is measured, and then the rotor assembly 30 is placed in the rotor transfer component 532. The code scanning component 533 (such as a laser scanner, a visual code reading camera) can read the unique identification of the rotor assembly 30, which is associated with the production batch, raw material information, processing equipment, process parameters and other data of the rotor assembly 30. If the outer diameter is unqualified, it will directly affect the matching accuracy with the bearing component 10. The out-of-tolerance rotor assembly 30 is rejected in real time to avoid it flowing into the subsequent press-fitting process, thereby reducing the scrapping of parts due to poor assembly.

[0071] Specifically, the rotor transfer assembly 532 includes a first sub-transfer assembly and a second sub-transfer assembly. The first sub-transfer assembly receives the rotor assembly 30 transferred by the rotor robot 531 and transports the rotor assembly 30 along the first direction X. The second sub-transfer assembly transfers the rotor assembly 30 to the second press-fitting mechanism 400 along the second direction Y. Among them, the bearing robot 521 transports the rotor assembly 30 from the first sub-transfer assembly to the second sub-transfer assembly. The first sub-transfer assembly transports along the first direction X (receiving the loading of the rotor robot 531), and the second sub-transfer assembly transports along the second direction Y (docking the second press-fitting mechanism 400). It can flexibly adapt to the overall layout of the production line, and the two can operate in parallel to shorten the cycle. Figure 15 As shown, the orange dotted line represents the transmission path of the rotor assembly 30 .

[0072] In some embodiments, combined Figure 15 The rotor end cover bearing assembly machine also includes a blanking mechanism 540, which includes a first blanking and transferring component 541. The head end of the first blanking and transferring component 541 is located downstream of the second press mechanism 400 and the first slide 120, and the end of the first blanking and transferring component 541 extends along the second direction Y to realize automatic blanking.

[0073] Specifically, the conveying mechanism 100 also includes a third positioning drive member 133, which is installed on the first slide 120 and is located downstream of the second pressing mechanism 400 on the first slide 120, corresponding to the head end position of the first blanking and transferring component 541. The output end of the third positioning drive member 133 abuts against the base 210 located on the first slide 120 along the second direction Y, so that the base 210 is clamped and fixed to the head end of the first blanking and transferring component 541.

[0074] In one embodiment, the unloading mechanism 540 includes a second unloading and transferring component 542 and a dust removal component 543. One end of the second unloading and transferring component 542 is docked with the first unloading and transferring component 541, and the other end of the second unloading and transferring component 542 extends along the first direction X. The dust removal component 543 is arranged next to the second unloading and transferring component 542 to make full use of the spatial layout.

[0075] Specifically, the dust removal component 543 includes a dust removal drive, a dust removal roller and a dust removal tape. The dust removal drive drives the dust removal roller to rotate. The dust removal tape is wrapped around the dust removal roller and fits with the rotor component 30 located in the second unloading and transferring component 542, driving the rotor component 30 to rotate to achieve 360° dust removal.

[0076] Specifically, the blanking mechanism 540 includes a visual inspection component 544, which is used to detect appearance defects and assembly accuracy of the product.

[0077] Specifically, the visual inspection component 544 and the dust removal component 543 are located on opposite sides of the second unloading and transferring component 542. Both of them reduce dust removal and visual inspection on the same product at the same time. The dust removal component 543 drives the product to rotate, so that the visual inspection component 544 can achieve 360° inspection.

[0078] Specifically, Figure 15 The blue dotted line in the figure represents the unloading path of the product.

[0079] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
