Description

Technical Field

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

[0002] The motor consists of a rotor and an end cover. During assembly, bearings are installed on the end cover to form a first component, and then the rotor is installed on the first component to form a second component.

[0003] Referring to Chinese Patent CN209767340U, the conveying assembly can transport 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. The conveying assembly transports the front cover to the front cover bearing assembly, where the bearing is installed onto the front cover, forming the first assembly. Then, the conveying assembly transports the front cover with the bearing installed to the rotor bearing assembly, where the rotor is inserted into the bearing on the front cover, forming the second assembly.

[0004] However, in existing rotor end cover bearing assembly machines, the bearings are prone to deformation during the pressing process of the bearings onto the end cover, resulting in a low yield rate. Summary of the Invention

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

[0006] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0007] A rotor end cover bearing assembly machine is provided, comprising:

[0008] The conveying mechanism includes a first conveying drive and a first slide extending along a first direction;

[0009] The tooling module includes a base, a positioning seat, a first elastic element, and a support column. The positioning seat is used for positioning and installing the end cap piece. The positioning seat has a first mounting hole corresponding to the shaft hole of the end cap piece. The support column is slidably installed in the first mounting hole in the vertical direction. The first elastic element is elastically compressed between the support column and the positioning seat. The positioning seat is slidably installed on the base in the vertical direction. The base is limited to the first slide rail on opposite sides in a second direction and slides in 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.

[0010] The first pressing mechanism includes a first pressing bracket, a first pressing drive and a first pressing assembly. The first pressing bracket is located next to the first slide rail. The first pressing drive is installed on the first pressing bracket and drives the first pressing assembly to perform lifting and lowering movements. The first pressing assembly is used to pick up the bearing component. Under the drive of the first pressing drive, the first pressing assembly presses the bearing component into the bearing hole.

[0011] The second pressing mechanism is distributed at intervals from the first pressing mechanism along the first direction. The second pressing mechanism picks up the rotor assembly and presses the shaft of the rotor assembly onto the inner ring of the bearing component.

[0012] The rotor end cover bearing assembly machine provided in this application embodiment has at least the following beneficial effects: the end cover part is positioned and installed on the positioning seat of the tooling module. The tooling module is initially located below the first pressing assembly or slides along the first direction to below the first pressing assembly under the drive of the first conveying drive. The first pressing assembly picks up the bearing part, and the first pressing drive drives the first pressing assembly to move downward in the vertical direction. When the bearing part is pressed into the bearing hole of the end cover part with interference fit, the positioning seat slides downward. The positioning seat and the end cover part positioned and installed on the positioning seat have floating properties to avoid rigid pressing. The support column is exposed in the first mounting hole. The inner ring of the bearing part is elastically supported by the elastic force of the first elastic element to avoid the outer ring being stressed and to offset the rigid compression of the inner ring by the pressing force. At the same time, it gradually moves downward elastically without hindering the pressing of the bearing part. After the bearing components are assembled, the first pressing mechanism is reset. 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 rotor shaft of the rotor assembly onto the inner ring of the bearing component. Since the bearing component does not deform and the bearing component and the shaft have high coaxiality, the yield of the assembled product is improved. Attached Figure Description

[0038] 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.

[0039] 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.

[0040] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, Y-axis, and Z-axis. The direction along the X-axis is vertical, the direction along the Y-axis is horizontal, and the direction along the Z-axis is vertical. The X-axis and Y-axis are two mutually perpendicular coordinate axes on the same horizontal plane, and the Z-axis is the vertical coordinate axis. The X-axis, Y-axis, and Z-axis lie on three mutually perpendicular planes in space: the XY-plane, the YZ-plane, and the XZ-plane. The XY-plane is horizontal, and the XZ-plane and YZ-plane are both vertical, with the XZ-plane perpendicular to the YZ-plane. Movement along these three axes in space refers to movement along the three mutually perpendicular axes in space, specifically movement along the X, Y, and Z axes. Planar movement, on the other hand, refers to movement within the XY-plane.

[0041] Please see Figure 1 The end cap 20 has a shaft hole 21 for the shaft 31 of the rotor assembly 30 to pass through and a bearing hole 22 for the assembly of the bearing member 10. The bearing hole 22 and the shaft hole 21 are connected, and the bearing hole 22 is located inside the shaft hole 21.

[0042] See Figure 2 The rotor end cover bearing assembly machine provided in this application embodiment includes a conveying mechanism 100, a tooling module 200, a first pressing mechanism 300, and a second pressing mechanism 400. See also Figure 4 The conveying mechanism 100 includes a first conveying drive 110 and a first slide rail 120 extending along a first direction X. See also Figure 3The tooling module 200 includes a base 210, a positioning seat 220, a first elastic element 230, and a support column 240. The positioning seat 220 is used for positioning and installing the end cap 20. The positioning seat 220 has a first mounting hole 221 corresponding to the shaft hole 21 of the end cap 20. The support column 240 is slidably installed in the first mounting hole 221 along the vertical direction Z. The first elastic element 230 is elastically compressed and disposed between the support column 240 and the positioning seat 220. The positioning seat 220 is slidably installed on the base 210 along the vertical direction Z. The base 210 is limited to the first slide rail 120 on opposite sides in the second direction Y, and slides along the first direction X under the drive of the first conveying drive member 110. The first direction X, the second direction Y, and the vertical direction Z are all perpendicular to each other.

[0043] See Figure 5 and Figure 6 The first pressing mechanism 300 includes a first pressing bracket 310, a first pressing drive 320, and a first pressing assembly 330. The first pressing bracket 310 is located beside the first slide rail 120. The first pressing drive 320 is mounted on the first pressing bracket 310 and drives the first pressing assembly 330 to perform lifting and lowering movements. The first pressing assembly 330 is used to pick up the bearing component 10. Under the drive of the first pressing drive 320, the first pressing assembly 330 presses the bearing component 10 into the bearing hole 22. Please refer back to the previous section. Figure 2 The second pressing mechanism 400 and the first pressing mechanism 300 are distributed at intervals along the first direction X. 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.

[0044] In this embodiment, the end cap 20 is positioned on the positioning seat 220 of the tooling module 200. The tooling module 200 is initially located below the first pressing assembly 330 or slides along the first direction X to below the first pressing assembly 330 under the drive of the first conveying drive 110. The first pressing assembly 330 picks up the bearing 10. The first pressing drive 320 drives the first pressing assembly 330 to move downward along the vertical direction Z. When the bearing 10 is pressed into the bearing hole 22 of the end cap 20 with interference fit, it drives the end cap 20 and the positioning seat 220 to move vertically downward relative to the base 210, with a downward floating amount to avoid rigid pressing. The support column 240 is exposed in the first mounting hole 221. With the help of the elastic force of the first elastic member 230, the inner ring of the bearing 10 is elastically supported, avoiding the outer ring from being stressed and offsetting the rigid compression of the inner ring by the pressing force. At the same time, it gradually moves downward elastically without hindering the pressing of the bearing 10. After the bearing component 10 is assembled, the first pressing mechanism 300 is reset. 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 high coaxiality with the rotating shaft 31, the yield of the assembled product is improved.

[0045] In some embodiments, combined with Figure 3 The tooling module 200 also includes a second elastic element 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 element 250 absorbs part of the pressure through deformation, so that the positioning seat 220 is vertically and elastically slidably installed on the base 210, avoiding damage to the end cap 20, the positioning seat 220 or the base 210 caused by rigid impact, and then transmitting the pressure to the base 210 and the first slide rail 120, preventing the end cap 20 and the tooling module 200 from being deformed by force, and realizing the limit in the vertical Z direction; moreover, after the press-fit is completed, the second elastic element 250 drives the positioning seat 220 to automatically reset.

[0046] Specifically, there are multiple second elastic elements 250, which are distributed circumferentially and equally around the first mounting hole 221, so that the positioning seat 220 is uniformly subjected to force and moves downward, preventing tilting or displacement due to uneven force, ensuring that the end cover 20 is always in a horizontal state, ensuring the coaxiality of the bearing 10 during press-fitting, and further reducing the risk of deformation of the bearing 10 due to tilting force.

[0047] Specifically, the elastic coefficient of the second elastic element 250 is smaller than the elastic coefficient of the first elastic element 230. Because the elastic coefficient of the second elastic element 250 is smaller, 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, providing a continuous and stable elastic clamping force for the inner ring of the bearing 10.

[0048] In some embodiments, combined with 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 passes through the other of the base 210 and the positioning seat 220 with a vertical Z-gap. The first guide member 260 ensures that the positioning seat 220 floats relative to the base 210 in the vertical Z-direction. During long-term reciprocating motion, without guidance, the mating surfaces of the base 210 and the positioning seat 220 may wear due to uneven friction, leading to an increase in the gap and further exacerbating the misalignment.

[0049] Optionally, the first guide member 260 is fixedly installed on the base 210, and the positioning seat 220 has a first guide hole for clearance fit of the first guide member 260. The upper end of the first guide member 260 is provided with a first limiting block that cannot pass through the first guide hole, thereby limiting the relative upward movement of the positioning seat 220.

[0050] 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, evenly spaced circumferentially distributed around the first mounting hole 221. The first guide members 260 and the second elastic members 250 lie on the same circular trajectory, ensuring that the elastic force and guiding constraint act on the same circumference, resulting in a more coordinated force transmission path and reducing additional torque caused by lever arm differences. The four second elastic members 250 are symmetrically distributed about the diameter of the two first guide members 260, ensuring that the elastic force of the positioning seat 220 is equal in any radial direction.

[0051] In some embodiments, combined with Figure 3 and Figure 6 The first elastic element 230 is sleeved onto the support column 240. The support column 240 strictly limits the deformation direction of the first elastic element 230, ensuring that the elastic force of the first elastic element 230 always acts on the support column 240 in the vertical direction Z.

[0052] In some embodiments, combined with Figure 6 The inner wall of the first mounting hole 221 is provided with a first step, and the support column 240 is provided with a second step. The first step and the second step are spaced apart vertically, and the two ends of the first elastic member 230 abut against the first step and the second step respectively.

[0053] In some embodiments, combined with Figure 3 The positioning base 220 is provided with a positioning pin 213, and the end cap 20 has a positioning hole 23. The positioning pin 213 is positioned and embedded in the positioning hole 23, so that the end cap 20 is positioned and installed on the positioning base 220. Optionally, there are two positioning pins 213, 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, to ensure that the end cap 20 is positioned and assembled on the positioning base 220 at a unique angle.

[0054] In some embodiments, combined with Figure 2 and Figure 4 The conveying mechanism 100 includes a pressing drive 181 and a pressing plate 182. The pressing drive 181 is installed on the first slide rail 120 and corresponds to the position of the second pressing mechanism 400. The pressing drive 181 drives the pressing plate 182 to move up and down, so as to press and fix the end cap 20 reaching the second pressing mechanism 400 onto the positioning seat 220. The downward pressure of the pressing plate 182 can directly counteract the upward reaction force, so that the positioning seat 220 and the first elastic member 230 remain relatively stationary during the pressing process.

[0055] Specifically, there are two pressing drive components 181 and two pressing plates 182. The two pressing plates 182 press on opposite sides of the end cap 20 along its length to ensure that the end cap 20 is subjected to uniform force and does not deform.

[0056] In some embodiments, combined with Figure 2 and Figure 3 The conveying mechanism 100 also includes a first positioning drive 131. The output end of the first positioning drive 131 abuts against the base 210 located on the first slide rail 120 along the second direction Y, so that the base 210 is clamped and fixed at the first pressing mechanism 300. When the tooling module 200 reaches the first pressing mechanism 300, the first positioning drive 131 presses and fixes the tooling module 200, facilitating the pressing operation. Otherwise, if the base 210 is in a floating state, it may experience slight tilting or shaking due to uneven force.

[0057] Optionally, the base 210 has a first positioning notch 211, and the output end of the first positioning drive 131 is embedded in the first positioning notch 211 to achieve mechanical locking, which restricts the degree of freedom of movement of the base 210 along the first direction X, prevents the base 210 from shaking along the first direction X during positioning, and improves positioning stability.

[0058] In some embodiments, combined with Figure 2 and Figure 3The conveying mechanism 100 also includes a second positioning drive 132. The output end of the second positioning drive 132 abuts against the base 210 located on the first slide rail 120 along the second direction Y, so that the base 210 is clamped and fixed at the second pressing mechanism 400. When the tooling module 200 reaches the second pressing mechanism 400, the second positioning drive 132 presses and fixes the tooling module 200, facilitating the pressing operation. Otherwise, if the base 210 is in a floating state, it may experience slight tilting or shaking due to uneven force.

[0059] Optionally, the base 210 has a first positioning notch 211, and the output end of the second positioning drive 132 is embedded in the first positioning notch 211 to achieve mechanical locking, which restricts the degree of freedom of movement of the base 210 along the first direction X, prevents the base 210 from shaking along the first direction X during positioning, and improves positioning stability.

[0060] In some embodiments, combined with Figure 2 and Figure 4 The conveying mechanism 100 also includes a second conveying drive 140, a third conveying drive 150, a fourth conveying drive 160, and a second slide rail 170. The second slide rail 170 and the first slide rail 120 are arranged in parallel. The fourth conveying drive 160 drives the tooling module 200 located on the second slide rail 170 to slide along the first direction X. The sliding directions of the tooling module 200 on the first slide rail 120 and the second slide rail 170 are opposite. The second conveying drive 140 drives the tooling module 200 located at the end of the first slide rail 120 to push towards the beginning of the second slide rail 170. The third conveying drive 150 drives the tooling module 200 located at the end of the second slide rail 170 to push towards the beginning of the first slide rail 120. Based on this, the tooling module 200 slides from the beginning to the end of the first slide rail 120 along the first direction X under the drive of the first conveying drive 110, moves from the end of the first slide rail 120 to the beginning of the second slide rail 170 under the drive of the second conveying drive 140, slides from the beginning to the end of the second slide rail 170 along the first direction X under the drive of the fourth conveying drive 160, and moves from the end of the second slide rail 170 to the beginning of the first slide rail 120 under the drive of the third conveying drive 150, so as to realize the cyclic reuse of the tooling module 200, reduce costs and ensure continuous production.

[0061] Optionally, the second conveying drive 140 drives the tooling module 200 to slide along the second direction Y. The third conveying drive 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 110, slides in the positive direction of the second direction Y under the drive of the second conveying drive 140, slides in the negative direction of the first direction X under the drive of the fourth conveying drive 160, and slides in the negative direction of the second direction Y under the drive of the third conveying drive 150.

[0062] Optionally, a third conveying drive 150 is mounted on top of the first conveying drive 110, and the output end of the third conveying drive 150 pushes the tooling module 200 from the side of the tooling module 200 away from the first slide rail 120. Specifically, the tooling module 200 has a second positioning notch 212, and 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 conveying drive 150 is embedded in the second positioning notch 212 to push the tooling module 200.

[0063] In some embodiments, combined with Figure 2 and Figure 3 The top of the first slide rail 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 against the top surface of the base 210. The first stop bar 121 is positioned closer to the second slide rail 170 than the second stop bar 122. Both ends of the first stop bar 121 are provided with circulation notches 123 to allow the tooling module 200 to enter and exit the first slide rail 120 through the circulation notches 123. The first stop bar 121 and the second stop bar 122 prevent the tooling module 200 from jumping up and down and shifting left and right during conveying, ensuring sliding accuracy. The design of the circulation notches 123 ensures that the circulation path is unobstructed and avoids production line stoppages caused by structural interference.

[0064] In some embodiments, combined with Figure 2 , Figure 5 and Figure 6 The first press-fit assembly 330 includes a first base 331 and a first positioning post 332. The first positioning post 332 is disposed on the first base 331 and is detachably embedded in the inner ring of the bearing component 10. The first positioning post 332 picks up the bearing component 10 and can be detachably separated from the bearing component 10 after press-fitting.

[0065] Specifically, the first seat 331 abuts against the upper end face of the bearing component 10, providing support for the bearing component 10. The support area is large, preventing the bearing component 10 from being suspended and deformed by force.

[0066] Specifically, the first positioning post 332 is embedded with a magnetic element 3321, which enables a detachable connection with the bearing component 10. After the bearing component 10 is press-fitted, the first pressing drive 320 drives the first positioning post 332 to move upward. Since the bearing component 10 is engaged in the bearing hole 22 of the end cover 20, the magnetic element 3321 naturally separates from the bearing component 10 during the upward movement, without the need for additional assembly or disassembly operations, thus avoiding the bearing component 10 being pulled out or the inner ring being deformed due to excessive interference or tightness.

[0067] Optionally, the magnetic component 3321 is an electromagnet or a permanent magnet. The magnetism of the electromagnet is controllable. When the magnetic component 3321 needs to be separated from the bearing component 10, the current to the electromagnet is cut off and the magnetism disappears, achieving resistanceless separation and avoiding force on the inner ring. Optionally, there are multiple magnetic components 3321, which are distributed circumferentially around the first positioning post 332. The circumferentially distributed magnetic components 3321 form a uniform annular magnetic field, and the magnetic force acts uniformly on the inner circumference of the bearing component 10. The circumferentially distributed magnetic components 3321 can form a symmetrical constraint, ensuring that the bearing component 10 is always coaxial with the first positioning post 332.

[0068] Specifically, in combination Figure 6 , Figure 7 and Figure 8 The first housing 331 is provided with a first annular step 3311, which abuts against the outer ring of the bearing component 10 to prevent the outer ring of the bearing component 10 from deforming under stress. The outer ring of the bearing component 10 is the core part that has an interference fit with the bearing hole 22 of the end cover. If the force is uneven or the local pressure is too large, plastic deformation is likely to occur, resulting in abnormal fit clearance with the end cover component 20. The first annular step 3311, by contacting the annular surface of the outer ring, evenly distributes the pressing force on the end face of the outer ring, avoids local stress concentration, prevents radial deformation of the outer ring due to off-center loading, and ensures the fit accuracy between it and the bearing hole 22.

[0069] Specifically, there is a gap between the first housing 331 and the inner ring of the bearing component 10. The inner ring is supported by the support column 240 and subjected to the flexible clamping force of the support column 240, which prevents relative compression between it and the outer ring and protects the fitting accuracy of the rolling elements and raceways inside the bearing component 10. If there is no gap between the inner ring and the first housing 331, the inner ring may be pushed upward by the support column 240 during press-fitting floating because the first housing 331 is fixed, causing axial misalignment between the inner and outer rings.

[0070] In some embodiments, combined with Figure 6 , Figure 8 and Figure 9The first pressing mechanism 300 includes a second positioning post 340, which is installed on the first pressing bracket 310 and located below the first slide rail 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 is coaxially arranged with the second positioning post 340, and thus the bearing component 10 is coaxially arranged with the first positioning post 332, ensuring the coaxiality of the bearing component 10 and the bearing hole 22 during assembly.

[0071] Specifically, the first slide rail 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 clearance hole 341, the upper end diameter of the first clearance hole 341 is larger than the lower end diameter of the support post 240, so that the second positioning post 340 avoids abutting against the support post 240 and avoids interfering with the elastic floating of the support post 240.

[0072] In some embodiments, combined with Figure 6 , Figure 8 and Figure 9 The first pressing assembly 330 also includes a second seat 335, a connecting post 336, and a first support ring 3371. The second seat 335 is connected to the output end of the first pressing drive 320. The second seat 335 is fixedly fitted onto the first seat 331. The connecting post 336 is fixedly installed on the second seat 335 and extends vertically downward. The first support ring 3371 is installed at the lower end of the connecting post 336 and 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 pressing.

[0073] Specifically, the first press-fit assembly 330 also includes a first elastic sleeve 333, a first support ring 3371 that is vertically slidably mounted on the connecting post 336, and the first elastic sleeve 333 that is sleeved on the connecting post 336. The first elastic sleeve 333 is compressible at the moment of press-fit contact, which buffers and reduces the impact speed and impact force, and avoids surface indentations or cracks on the end cap 20.

[0074] Specifically, the first pressing assembly 330 also includes a second support ring 3372, which is embedded at the bottom of the first support ring 3371. The second support ring 3372 is used to press the top of the end cap 20, and is made of plastic. Compared with metal parts, plastic parts have lower rigidity and are elastic. When the second support ring 3372 presses the end cap 20, it can reduce the contact stress between the two.

[0075] In some embodiments, the first positioning pin 332 is vertically slidably inserted through the first base 331. The first pressing assembly 330 further includes a pin drive 334, which is mounted on the second base 335. The pin drive 334 drives the first positioning pin 332 to move vertically. Based on this, when the first pressing assembly 330 descends to the point where the bearing member 10 abuts against the opening of the bearing hole 22, the first positioning pin 332 is inserted into the bearing hole 22. Its axial reference ensures that the bearing member 10 and the bearing hole 22 are coaxial, completing the alignment. The pin drive 334 then drives the first positioning pin 332 to rise, preventing the inner ring from being stressed during pressing.

[0076] Specifically, the first press-fit assembly 330 also includes an adapter 338 and a first housing 339. One end of the first housing 339 is connected to the second base 335, and the other end of the first housing 339 is connected to the adapter 338. The connecting post 336 is installed on the adapter 338, that is, the connecting post 336 is indirectly installed on the second base 335 through the adapter 338 and the first housing 339. The cavity enclosed by the first housing 339 is used to protect the electrical connection of the post drive 334, and the cavity helps to reduce weight.

[0077] In one embodiment, combined Figure 2 The rotor end cover bearing assembly machine also includes a dust collection component 350, which is located between the first pressing mechanism 300 and the second pressing mechanism 400. The dust collection component 350 is installed on the first pressing bracket 310 and is used to cover the tooling module 200 located downstream of the first pressing mechanism 300 to complete the dust collection operation. This is to remove impurities generated after the first pressing mechanism 300 presses, and to provide a clean tooling module 200 for the pressing of the second pressing mechanism 400.

[0078] In some embodiments, combined with Figure 2 , Figure 10 and Figure 11 The second pressing mechanism 400 includes a second pressing bracket 410, a second pressing drive 420, and a lifting drive 430. The support column 240 has a second clearance hole 242. The output end of the lifting drive 430 is connected to a first lifting shaft 431, which is vertically and vertically inserted into the second clearance hole 242. The second pressing drive 420 is mounted on the second pressing bracket 410 and located above the first slide rail 120. The output end of the second pressing drive 420 is connected to the second lifting shaft 421, and the second lifting shaft 421 and the first lifting shaft 431 are coaxially arranged.

[0079] The rotor assembly 30 is automatically fed by a robotic arm or manually fed to the second pressing mechanism 400. The two ends of the rotating shaft 31 of the rotor assembly 30 are clamped by the first lifting shaft 431 and the second lifting shaft 421, respectively. Then, the first lifting shaft 431 and the second lifting shaft 421 descend synchronously, and the rotor assembly 30 descends synchronously and is pressed into the inner ring of the bearing component 10 and the movable through shaft hole 21. During the descent of the rotating shaft 31, both ends are supported simultaneously to avoid swaying in the suspended state. The second lifting shaft 421 and the first lifting shaft 431 are coaxially arranged, which improves the coaxiality between the rotor assembly 30 and the end cover component 20 and avoids motor eccentricity, centrifugal force during operation, vibration and noise caused by insufficient coaxiality.

[0080] In some embodiments, the end of the first lifting shaft 431 has a first tapered body, which is used to be fitted into the end of the rotating shaft 31. The first tapered body forms a line contact guide with the concave hole at the end of the rotating shaft 31, further preventing axial movement or circumferential oscillation at the end of the rotating shaft 31.

[0081] In one embodiment, combined Figure 12 and Figure 13 The second lifting shaft 421 has a second conical body 422 at its end. The second conical body 422 is used to be fitted into 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 conical body 422 and the concave hole at the end of the rotating shaft 31 form a line contact guide to further prevent axial movement or circumferential swing at the end of the rotating shaft 31.

[0082] In one embodiment, the second lifting shaft 421 is elastically mounted to the output end of the second press-fitting drive 420. When the second lifting shaft 421 contacts the rotating shaft 31, its elastic mounting absorbs initial impact energy, preventing damage to the end face or displacement of the rotating shaft 31 caused by rigid mounting. The elastic mounting ensures that the second lifting shaft 421 remains stably in contact with the top of the rotating shaft 31, continuously providing axial support and preventing the top of the rotating shaft 31 from separating from the second lifting shaft 421. The elastic mounting also ensures that the second lifting shaft 421 remains in contact with the top of the rotating shaft 31, preventing shaking of the rotating shaft 31 due to momentary disengagement even when the speed of the second press-fitting drive 420 fluctuates or vibrates.

[0083] In one embodiment, the second pressing mechanism 400 further includes a third elastic element 440, a third seat 461, and a fourth seat 462. The fourth seat 462 is mounted on the output end of the second pressing drive 420, and the third seat 461 is mounted on the lower end of the fourth seat 462. The third elastic element 440 is housed within the fourth seat 462, with one end abutting against the inner wall of the fourth seat 462 and the other end abutting against the second lifting shaft 421. The end of the second lifting shaft 421 extends vertically and elastically from the lower surface of the third seat 461 to abut against the rotating shaft 31. The third elastic element 440 absorbs the initial impact force through its own deformation, allowing the second lifting shaft 421 to flexibly fit against the rotating shaft 31. The structural design of the third seat 461 and the fourth seat 462 provides dual guidance for the elastic compression direction of the second lifting shaft 421, improving motion accuracy. The fourth seat 462 has a blind hole. One end of the third elastic member 440 abuts against the bottom of the blind hole, and the other end is sleeved with the second lifting shaft 421. The third seat 461 has a through hole for the second lifting shaft 421 to protrude from its lower end face. The second lifting shaft 421 has a step, which abuts against the upper end of the through hole to prevent the second lifting shaft 421 from falling off.

[0084] Optionally, the second pressing mechanism 400 further includes a second housing 463, which includes a third seat 461 and a fourth seat 462, thereby improving the connection strength between the two and indirectly enhancing the structural stability of the entire elastic mounting assembly, and preventing the third seat 461 from undergoing minor deformation due to long-term pressing reaction force.

[0085] In some embodiments, the first slide rail 120 has a second support hole 125, and the second pressing mechanism 400 further includes a third positioning post 450. The third positioning post 450 is installed on the second pressing bracket 410 and located below the first slide rail 120, and is disposed within the second support hole 125. The third positioning post 450 has a third clearance hole 451, which is coaxially arranged with the first lifting shaft 431. The third clearance hole 451 provides protection and guidance for the lifting movement of the first lifting shaft 431. Specifically, for the elongated first lifting shaft 431, the wall of the third clearance hole 451 can provide radial support, reducing its bending deformation under stress and ensuring the stability of the lifting action.

[0086] In some embodiments, combined with Figure 2 The rotor end cover bearing assembly machine includes a worktable 610, a conveying mechanism 100, a first pressing mechanism 300, and a second pressing mechanism 400 mounted on the worktable 610. The worktable 610 provides a uniform mounting base and level reference.

[0087] Specifically, in combination Figure 14The rotor end cover bearing assembly machine includes a working cover 620, which covers the conveying mechanism 100, the first pressing mechanism 300, and the second pressing mechanism 400, avoiding external interference to the pressing operation and providing support for the efficient, stable, and safe operation of the rotor end cover bearing assembly machine.

[0088] Specifically, the rotor end cover bearing assembly machine includes a controller, which is installed below the workbench 610, while the conveying mechanism 100, the first pressing mechanism 300, and the second pressing mechanism 400 are located above the workbench 610. The workbench 610 serves as a physical divider, avoiding the concentrated stacking of various components, achieving separation between dynamic and static components, and making the overall structure of the equipment more compact.

[0089] In some embodiments, combined with Figure 15 The rotor end cover bearing assembly machine also includes an end cover feeding mechanism 510. The end cover feeding mechanism 510 includes an end cover robot 511 and an end cover transfer assembly 512. The end cover robot 511 picks up a single end cover piece 20 sequentially and transfers it to the end cover transfer assembly 512. The end cover transfer assembly 512 then linearly transports the end cover piece 20 to the positioning seat 220 located in the first slide rail 120, thereby realizing the automatic feeding of the end cover piece 20.

[0090] Specifically, the end cap feeding mechanism 510 includes an end cap storage chamber 513. The end cap storage chamber 513 centrally stores a certain number of end cap parts 20, ensuring the continuity and precision of the production line.

[0091] Specifically, the end cap transfer assembly 512 includes a first cap transfer assembly 514 and a second cap transfer assembly 515, both extending along the second direction Y. One end of the first cap transfer assembly 514 is within the operating range of the end cap robot 511, and the other end of the first cap transfer assembly 514 is connected to one end of the second cap transfer assembly 515. The second cap transfer mechanism clamps the end cap piece 20 and horizontally feeds it along the second direction Y to above the positioning seat 220 on the first slide rail 120. The two-section design can flexibly adapt to the overall layout of the equipment, for example, by staggering the feeding path of the rotor assembly 30 in the height direction. Both cap transfer assemblies convey along the second direction Y, avoiding positioning errors caused by directional changes and reducing the volume occupied. The first cap transfer assembly 514 also serves as a receiver and buffer.

[0092] Specifically, the end cap material storage 513, the end cap robot 511, the first cap transfer component 514 and the second cap transfer component 515 are arranged sequentially along the second direction Y to realize the linear transmission of the end cap component 20 without any unnecessary turning or crossing. The linear arrangement can maximize the use of the space in the second direction Y. Figure 15 The red dashed line in the diagram represents the conveying path of the end cap 20.

[0093] In some embodiments, combined with Figure 15The rotor end cover bearing assembly machine also includes a bearing feeding mechanism 520, which includes a bearing robot 521 and a bearing transfer assembly 522. The bearing robot 521 picks up individual bearing parts 10 sequentially and transfers them to the bearing transfer assembly 522. The bearing transfer assembly 522 then linearly transports the bearing parts 10 to the first pressing assembly 330, thus achieving automated continuous feeding.

[0094] Specifically, the bearing feeding mechanism 520 includes a bearing storage 523 and a pushing assembly 524. The bearing storage 523 stores bearings, and the pushing assembly 524 stacks bearings and uses gravity to push the bearing components 10 sequentially from the bottom. The bearing robot 521 then picks up and places the pushed bearing components 10 into the bearing transfer robot. Compared to a distributed rack, the bearing storage 523 can store a large number of bearing components 10 by stacking them, increasing storage capacity within a limited space. The pushing assembly 524 pushes the bearing components 10 sequentially from the bottom, and new bearing components 10 can be added to the top at any time without stopping the machine for replenishment, further improving the continuity of material supply. During the stacking storage and gravity pushing process of the pushing assembly 524, the bearing components 10 fall slowly only within the guide groove of the pushing assembly 524, maximizing the protection of the precision surface and dimensional accuracy of the bearing components 10.

[0095] Specifically, the bearing material storage 523 and the end cap material storage 513 are spaced apart along the first direction X and located on the same side of the worktable 610, forming a compact layout. The bearing material storage 523, the pushing 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 pushing 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 dashed line represents the transmission path of bearing component 10.

[0096] In some embodiments, combined with Figure 15 The rotor end cover bearing assembly machine also includes a rotor feeding mechanism 530, which includes a rotor robot 531 and a rotor transfer component 532. The rotor robot 531 picks up individual rotor components 30 sequentially and transfers them to the rotor transfer component 532. The rotor transfer component 532 then transports the rotor components 30 to the second pressing mechanism 400, achieving efficient and continuous feeding.

[0097] Specifically, the rotor loading mechanism 530 includes a barcode scanning component 533 and an outer diameter acquisition component 534. The rotor robot 531 grips a single rotor assembly 30 from the outside and places it into the scanning component for barcode scanning. Then, the rotor assembly 30 is gripped into the outer diameter acquisition component 534 to measure its outer diameter, and subsequently placed into the rotor transfer component 532. The barcode scanning component 533 (such as a laser barcode scanner or a visual barcode reader) can read the unique identifier on the rotor assembly 30, which is associated with data such as the production batch, raw material information, processing equipment, and process parameters of the rotor assembly 30. If the outer diameter is unqualified, it will directly affect the fitting accuracy with the bearing component 10. Rotor assemblies 30 exceeding the tolerance are rejected in real time to prevent them from flowing into subsequent pressing processes and reduce part scrap due to poor assembly.

[0098] 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 from the rotor robot 531 and transports it along a first direction X. The second sub-transfer assembly transports the rotor assembly 30 along a second direction Y to the second pressing mechanism 400. The bearing robot 521 moves 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 feed from the rotor robot 531), and the second sub-transfer assembly transports along the second direction Y (connecting to the second pressing mechanism 400), flexibly adapting to the overall layout of the production line. Both can operate in parallel, shortening the cycle time. Figure 15 As shown, the orange dashed line represents the transmission path of the rotor assembly 30.

[0099] In some embodiments, combined with Figure 15 The rotor end cover bearing assembly machine also includes a feeding mechanism 540, which includes a first feeding and transfer component 541. The first end of the first feeding and transfer component 541 is located downstream of the second pressing mechanism 400 in the first slide rail 120, and the end of the first feeding and transfer component 541 extends along the second direction Y to achieve automatic feeding.

[0100] Specifically, the conveying mechanism 100 also includes a third positioning drive 133, which is installed on the first slide rail 120 and located downstream of the second pressing mechanism 400 in the first slide rail 120, corresponding to the first end position of the first unloading and transfer assembly 541. The output end of the third positioning drive 133 abuts against the base 210 located in the first slide rail 120 along the second direction Y, so that the base 210 is clamped and fixed to the first end of the first unloading and transfer assembly 541.

[0101] In one embodiment, the feeding mechanism 540 includes a second feeding and transfer component 542 and a dust removal component 543. One end of the second feeding and transfer component 542 is connected to the first feeding and transfer component 541, and the other end of the second feeding and transfer component 542 extends along the first direction X. The dust removal component 543 is disposed next to the second feeding and transfer component 542 to make full use of the space layout.

[0102] Specifically, the dust removal assembly 543 includes a dust removal drive, a dust removal roller, and a dust removal cloth. The dust removal drive drives the dust removal roller to rotate, and the dust removal cloth is wrapped around the dust removal roller and attached to the rotor assembly 30 located in the second unloading and transfer assembly 542, thereby driving the rotor assembly 30 to rotate and achieving 360° dust removal.

[0103] Specifically, the unloading mechanism 540 includes a vision inspection component 544, which is used to detect appearance defects and assembly accuracy of the product.

[0104] Specifically, the vision inspection component 544 and the dust removal component 543 are located on opposite sides of the second unloading and transfer component 542. The two components simultaneously perform dust removal and vision inspection on the same product. The dust removal component 543 drives the product to rotate, thereby enabling the vision inspection component 544 to perform 360° inspection.

[0105] Specifically, Figure 15 The blue dashed line in the image represents the product's feeding path.

[0106] It should be understood that the sequence number of each step in the above embodiments does not imply 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.
