[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Understandably, referring to Figure 1 , Figure 2 and Figure 5The rotor bearing mounting device of this utility model includes a snap ring pressing mechanism 100, a bearing pressing mechanism 200, and a feeding mechanism 300. The snap ring pressing mechanism 100 includes a first positioning seat 110 and a first driving member 120. The first positioning seat 110 is used to receive the rotor, and storage rods 111 are connected to both sides of the first positioning seat 110. The storage rods 111 are used to store snap rings, and the snap rings can slide on the storage rods 111. The first driving member 120 is used to drive the snap rings to be pressed into the rotor. The bearing pressing mechanism 200 includes a second positioning seat 210 and a... The second driving member 220 and the second positioning seat 210 are used to receive the rotor. Both sides of the second positioning seat 210 are provided with storage cylinders 211 for storing bearings. The lower end of the storage cylinder 211 has an opening 212. The second driving member 220 is used to drive the bearing to press into the rotor through the opening 212. The feeding mechanism 300 includes a support platform 310 and a moving component 320. The support platform 310 is used to receive the rotor, and the moving component 320 is used to drive the support platform 310 to move between the first positioning seat 110 and the second positioning seat 210.

[0032] The rotor is placed on the support platform 310. The moving component 320 can drive the support platform 310 to move between the first positioning seat 110 and the second positioning seat 210, so that the rotor can be placed on the first positioning seat 110. Two storage rods 111 are respectively arranged on both sides of the first positioning seat 110. The retaining spring is sleeved on the storage rod 111, so that the retaining spring can slide on the storage rod 111 and be output from the storage rod 111. The first driving member 120 can drive the retaining spring to move towards the rotor, so that the retaining spring can be pressed in. In the rotor, the moving component 320 drives the support platform 310 to move, so that the support platform 310 can transport the rotor from the first positioning seat 110 to the second positioning seat 210. The bearing is stored in the storage cylinder 211, and the lower end of the storage cylinder 211 has an opening 212 so that the bearing can be output from the opening 212 of the storage cylinder 211. The second driving component 220 can drive the bearing to be pressed into the rotor, and make the rotor abut against the snap ring, thereby realizing the automated pressing of the bearing, replacing manual operation, and improving the production efficiency and production quality of the rotor.

[0033] It should be noted that the first driving component 120 and the second driving component 220 can both be linear cylinders, electric actuators, linear slide modules, etc., so that the first driving component 120 can drive the retaining ring to be pressed onto the rotor from the storage rod 111, and the second driving component 220 can drive the bearing to be pressed onto the rotor from the opening 212.

[0034] Furthermore, the storage rod 111 is L-shaped, allowing the retaining ring at its input end to slide vertically downwards. This, in turn, pushes the retaining ring at its output end horizontally, enabling the retaining ring to automatically exit the storage rod 111. This facilitates the pressing of the retaining ring onto the rotor via the first drive member 120. The width of the storage cylinder 211 matches the diameter of the bearing, ensuring that the storage cylinder 211 can accommodate only one bearing in its width direction. This allows for the individual output of bearings, preventing them from piling up and improving the pressing stability of the bearings.

[0035] Understandably, referring to Figure 1 and Figure 4 The first positioning seat 110 has a positioning groove 112 for accommodating the rotor. The positioning groove 112 includes a limiting part 113 and an inclined part 114. The limiting part 113 is connected to the lower end of the inclined part 114, and the width of the limiting part 113 matches the rotor. The inclined part 114 is used to guide the rotor to roll into the limiting part 113. The first positioning seat 110 has a positioning groove 112, which includes a limiting part 113 and an inclined part 114. The inclined part 114 is located above the limiting part 113. The moving component 320 can drive the support platform 310 to move onto the first positioning seat 110, so that the rotor can fall from the support platform 310 into the inclined part 114. The inclined part 114 guides the rotor to roll smoothly into the limiting part 113, simplifying the rotor placement operation and facilitating the positioning of the rotor. The width of the limiting part 113 matches the rotor, so that both sides of the limiting part 113 abut against the rotor, thereby preventing the rotor from shaking within the limiting part 113, making the rotor more stable during the pressing of the snap ring, and improving the pressing efficiency of the snap ring.

[0036] It should be noted that the inclined portion 114 is a conical space opened on the first positioning seat 110, which can guide the rotor to roll when the rotor falls into the inclined portion 114, so that the rotor can fall smoothly into the limiting portion 113.

[0037] Understandably, referring to Figures 1 to 3The first positioning seat 110 is provided with a positioning assembly 130, which includes a positioning rod 131, a push block 132, and a third driving member 133. The positioning rod 131 is connected to one side of the first positioning seat 110, and the push block 132 is connected to the movable end of the third driving member 133. The third driving member 133 is used to drive the push block 132 to move closer to the positioning rod 131, so as to drive the rotor to abut against the positioning rod 131. The positioning rod 131 and the push block 132 are respectively arranged on both sides of the first positioning seat 110, and the push block 132 is connected to the movable end of the third driving member 133. The third driving member 133 can drive the push block 132 to move closer to or away from the positioning rod 131, so that the positioning rod 131 and the push block 132 can cooperate to clamp the rotor, thereby axially positioning the rotor on the first positioning seat 110, avoiding rotor position shaking during snap ring pressing, and improving the snap ring pressing quality.

[0038] It should be noted that the third drive component 133 can be a linear cylinder, an electric actuator, a linear slide module, etc., and is not limited here.

[0039] Specifically, refer to Figure 2 and Figure 3 The positioning assembly 130 also includes an adjusting seat 134, which is fixedly connected to the first positioning seat 110. The positioning rod 131 is threadedly connected to the adjusting seat 134. The adjusting seat 134 is fixedly connected to the first positioning seat 110. By setting the positioning rod 131 and the adjusting seat 134 to be threadedly connected, the positioning rod 131 can move axially when the drive positioning rod 131 rotates. This allows for convenient adjustment of the position of the positioning rod 131 in the adjusting seat 134, thereby facilitating the adjustment of the rotor's position and allowing for adjustment of the snap ring's press-fit position, improving ease of use.

[0040] Specifically, refer to Figure 2 and Figure 3 The positioning assembly 130 also includes a nut 135, which is threadedly connected to the positioning rod 131 and abuts against the adjusting seat 134. The threaded connection between the nut 135 and the positioning rod 131, along with the abutment between the nut 135 and the adjusting seat 134, allows the nut 135 to lock the positioning rod 131 onto the adjusting seat 134, preventing the positioning rod 131 from shifting and thus improving the rotor's positional stability and the pressing quality of the retaining ring.

[0041] It should be noted that when adjusting the position of the positioning rod 131, first loosen the nut 135 to separate the nut 135 from the adjusting seat 134, thereby unlocking the position of the positioning rod 131 and allowing the positioning rod 131 to rotate to adjust its position. Then tighten the nut 135 so that the nut 135 abuts against the adjusting seat 134 to lock the position of the positioning rod 131.

[0042] Understandably, referring to Figure 1 , Figure 5 and Figure 6 The bearing press-fitting mechanism 200 also includes a guide cylinder 230, which has a guide portion 231 and a straight cylinder portion 232. One end of the guide portion 231 is connected to the opening 212, and the other end of the guide portion 231 is connected to the straight cylinder portion 232. The guide portion 231 is tapered, and the inner diameter of the straight cylinder portion 232 matches the diameter of the bearing. The guide cylinder 230 is arranged between the storage cylinder 211 and the second positioning seat 210. The guide cylinder 230 has a guide portion 231 and a straight cylinder portion 232. By setting the shape of the guide portion 231 to be tapered, when the second driving member 220 drives the bearing to output from the opening 212 to the guide portion 231, the guide portion 231 can guide the bearing to slide smoothly into the straight cylinder portion 232, so that the bearing can be smoothly aligned with the rotor, which facilitates the smooth press-fitting of the bearing onto the rotor and improves the press-fitting stability of the bearing.

[0043] It should be noted that by setting the guide portion 231 to a tapered shape, the second drive member 220 can push the bearing against the inner wall of the guide portion 231, thereby guiding the direction of the bearing's movement and allowing the bearing to slide smoothly into the straight cylinder portion 232. By setting the inner diameter of the straight cylinder portion 232 to match the diameter of the bearing, the bearing can be aligned with the rotor, and the bearing's movement deviation can be avoided, thus improving the pressing quality.

[0044] Specifically, refer to Figure 1 , Figure 5 and Figure 6 A notch 233 is provided at the end of the straight cylindrical section 232 away from the guide section 231, allowing the rotor to enter the straight cylindrical section 232 through the notch 233. The notch 233 is located at the end of the straight cylindrical section 232 away from the guide section 231 and at the upper end of the straight cylindrical section 232. This allows the end of the rotor to extend into the straight cylindrical section 232 through the notch 233 when the support platform 310 drives the rotor to be placed on the second positioning seat 210. This facilitates the positioning of the rotor, prevents the rotor from getting stuck on the guide cylinder 230 during transportation, and improves the transportation efficiency of the rotor.

[0045] Understandably, referring to Figure 1 and Figure 5The bearing press-fitting mechanism 200 also includes a fixing component 240, which includes a fourth driving member 241 and a pressing block 242. The pressing block 242 is connected to the movable end of the fourth driving member 241 and is located above the second positioning seat 210. The fourth driving member 241 drives the pressing block 242 to move closer to the second positioning seat 210. The pressing block 242 is located above the second positioning seat 210 and is connected to the movable end of the fourth driving member 241. The fourth driving member 241 can drive the pressing block 242 to move closer to the second positioning seat 210, so that the pressing block 242 can press the rotor firmly onto the second positioning seat 210, thereby preventing rotor position wobbling during bearing press-fitting and improving the bearing press-fitting quality.

[0046] It should be noted that the fourth drive component 241 can be a linear cylinder, an electric actuator, a linear slide module, etc., and is not limited here.

[0047] Understandably, referring to Figure 1 The moving component 320 includes a horizontal drive member 321 and a vertical drive member 322. The vertical drive member 322 is connected to the movable end of the horizontal drive member 321, and the support platform 310 is connected to the movable end of the vertical drive member 322. The horizontal drive member 321 and the vertical drive member 322 cooperate to drive the support platform 310 to move in a vertical plane. The vertical drive member 322 is connected to the movable end of the horizontal drive member 321, and the support platform 310 is fixedly connected to the movable end of the vertical drive member 322. Through the cooperation of the horizontal drive member 321 and the vertical drive member 322, the support platform 310 can move in a vertical plane, thereby facilitating the transport of the rotor between the first positioning seat 110 and the second positioning seat 210, replacing manual handling, and improving production efficiency.

[0048] It should be noted that during rotor handling, the horizontal drive 321 drives the vertical drive 322 and the support platform 310 to move synchronously in the horizontal direction, so that the support platform 310 can move to below the first positioning seat 110 or the second positioning seat 210. Then, the vertical drive 322 drives the support platform 310 to rise, so that the rotor can be transferred from the first positioning seat 110 or the second positioning seat 210 to the support platform 310. Then, the horizontal drive 321 drives the vertical drive 322 and the support platform 310 to move, so as to change the position of the support platform 310. Finally, the vertical drive 322 drives the support platform 310 to fall, so that the rotor can be transferred to the first positioning seat 110 or the second positioning seat 210. This can replace manual rotor handling and improve production efficiency.

[0049] The horizontal drive component 321 and the vertical drive component 322 can both be linear cylinders, electric actuators, linear slide modules, etc., and are not limited here.

[0050] Specifically, refer to Figure 1 The upper end of the support platform 310 is provided with a V-shaped groove 311, which can accommodate the rotor. By providing a V-shaped groove 311 at the upper end of the support platform 310, the rotor can be prevented from rolling on the support platform 310, so that the rotor can be stably and accurately arranged on the support platform 310, thereby improving the handling stability of the rotor and reducing the possibility of the rotor falling off.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
