Description

Technical Field

[0001] This utility model relates to the technical field of rotor bearing equipment, specifically rotor bearing assembly. Background Technology

[0002] When using precision rolling bearings, the installation process is crucial to achieve the highest speed and the lowest temperature rise. When assembling bearings on a rotor, the assembly methods for the rotor and the inner ring of the bearing to have an interference fit (tight fit) are usually either hydraulic press-fit or heat-insertion. Regardless of the method used, it is necessary to minimize the impact of assembly and maintain the precision of the bearing. Currently, the assembly process of the traditional rotor and its bearings at both ends is very mature, but some problems still exist in actual work. First, the bearing needs to be distinguished between the front and back during installation, but the current manual method of distinguishing them is inefficient; Secondly, considering that the bearing inner bores are the same, when the press faces of the two bearings are aligned with the two ends of the rotor and pressed in, even if the pressing force is the same, an error will occur between a certain bearing and the rotor. Therefore, this application proposes a rotor pressure bearing assembly. Utility Model Content

Detailed Implementation

[0017] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 8The present invention preferably provides the following technical solution: a rotor bearing assembly, comprising: a frame 111; two sets of bearing unloading mechanisms symmetrically arranged in the middle of the frame 111, each set of bearing unloading mechanisms being provided with a detection and correction component for identifying the front and back sides of the bearings during unloading and performing correction work when the back side is identified; and a holding platform arranged on the frame 111 and placed between the two sets of bearing unloading mechanisms for supporting the rotor; and a double-pressure bearing mechanism arranged on the frame 111, which, when the double-pressure bearing mechanism is working, can evenly press the two bearings released by the two sets of bearing unloading mechanisms onto both ends of the rotor on the holding platform.

[0019] The assembly process of the traditional rotor and its bearings at both ends is very mature, but some problems still exist in actual work, such as the precise alignment of the bearings and the precise pressing of the bearings. Therefore, this application proposes a rotor pressing bearing assembly. Specifically, considering the need to distinguish the front and back sides of a bearing, a design was devised to differentiate and correct the bearing's orientation. For example... Figure 1 , 3 As shown in Figures 4 and 6, the two sets of bearing unloading mechanisms in the middle of the frame 111 are respectively equipped with detection and correction components. These components are used to identify the front and back of the bearing at the unloading position of the bearing unloading mechanism and to perform correction work when the back is identified, so as to ensure that the pressing surfaces of the two bearings are aligned with the two ends of the rotor and achieve precise assembly. Considering that the inner bores of the bearings are all the same, when the pressing faces of the two bearings are aligned with the two ends of the rotor and pressed in, even if the pressing force is the same, an error will occur between one of the bearings and the rotor. Therefore, this application also provides a double-pressure bearing mechanism near the holding platform where the rotor is placed. When the double-pressure bearing mechanism is working, it can evenly press the two bearings released by the two sets of bearing feeding mechanisms onto the two ends of the rotor on the holding platform, ensuring the dimensional stability of the bearings at both ends of the rotor.

[0020] Example 2 In another embodiment of this utility model, each bearing unloading mechanism includes a cylinder 226 fixed on the frame 111, with a rectangular groove on one side of the cylinder 226; a conveying pipe 227, an assembly base 228, and an unloading pipe 230 sequentially assembled and fixed along the bearing unloading direction, with the inlet end of the conveying pipe 227 passing through the rectangular groove and connected to the cylinder 226; a transfer groove 231 is provided inside the assembly base 228, and the transfer groove 231 is composed of a vertical section and an inclined section. The vertical section of the transfer groove 231 can accommodate three bearings, and its top end is connected to the unloading end of the conveying pipe 227, while its end end of the inclined section is connected to the inlet end of the unloading pipe 230; a hollow circular frame 2302 is provided at the unloading end of the unloading pipe 230, wherein the hollow circular frames 2302 where the two bearing unloading mechanisms are located are placed on both sides of the holding platform; and a steering component is also provided inside the assembly base 228 for steering the unloading of the bearings. Furthermore, the steering component includes a second rotary cylinder 232 internally disposed in the mounting base 228, and a support shaft 233 fixed to the output end of the second rotary cylinder 232. The end of the support shaft 233 away from the second rotary cylinder 232 extends upward to the lower part of the vertical section of the transfer groove 231 and has a groove 234. The groove 234 is used to accommodate a single bearing. When the detection and correction component identifies the single bearing in the transfer groove 231 as facing forward and the bearing enters the groove 234, the second rotary cylinder 232 drives the groove 234 to rotate 90° and connect it to the inclined section of the transfer groove 231, thus achieving material discharge. When the detection and correction component identifies the single bearing in the transfer groove 231 as facing backward and the bearing... When the bearing enters the groove 234, the second rotary cylinder 232 drives the groove 234 to rotate 270° for the bearing to be flipped and discharged. Furthermore, the detection and correction assembly includes a color sensor 235 disposed on one side of the mounting base 228 and a first through groove opened on one side of the mounting base 228. The first through groove is used for the detection end of the color sensor 235 to align with the bearing in the middle of the vertical section of the transfer groove 231 and perform detection work. Furthermore, a second telescopic cylinder 236 is also disposed on the side of the mounting base 228 away from the color sensor 235. The output shaft of the second telescopic cylinder 236 passes through the second through groove opened on the mounting base 228 and is embedded in the bearing center at the top of the vertical section of the transfer groove 231.

[0021] like Figure 4 , 5 As shown in Figures 6 and 7, in this embodiment, the cylinder 226, the material conveying pipe 227, the transfer groove 231 inside the assembly base 228, the discharge pipe 230, and the hollow circular frame 2302 are sequentially connected and used for the linear discharge of several bearings, as shown in Figures 7 and 8. Figure 6 As shown, the transfer groove 231 consists of a vertical section and an inclined section, and the vertical section of the transfer groove 231 can accommodate three bearings. The bearing positioned on the upper part of the vertical section is connected via... Figure 4 , 5 The second telescopic cylinder 236 shown in 6 is used to limit the bearing at that position. This design can provide the bearing below it with turning space and time. The bearing in the middle position is always in a ready state, such as Figure 7As shown, when the bearing in the middle position is detected by the color sensor 235, if the detection result is positive, the bearing in the middle position can enter the groove 234 when the bearing is discharged from the groove 234. At this time, the second rotary cylinder 232 rotates 90°, and at the instant the groove 234 is aligned with the inclined section of the transfer groove 231, the bearing that was originally in the middle position immediately enters the inclined section of the transfer groove 231, the discharge pipe 230, and the hollow circular frame 2302 to realize the pre-pressing preparation of the bearing. If the detection result is negative, after the bearing enters the groove 234, the second rotary cylinder 232 rotates 180° + 90°. Here, 180° is used for flipping the bearing, and 90° is used for discharging after flipping. The bearing at the bottom position is built into the groove 234 at the top of the support shaft 233. The bearing at this position has been tested on both sides. It is worth noting that the color sensor 235 here is a mature existing technology. It is an output device that detects the color of an object through photoelectric conversion and compares it with a preset reference value. Since existing bearings mostly use color to indicate the front of the surface, the color sensor 235 set in this application is used for the color of the device and sends the signal to the microcontroller. The microcontroller controls the second rotary cylinder 232 to execute the corresponding instructions.

[0022] Example 3 In another embodiment of this utility model, the holding platform includes a first fixing block 215 and a second fixing block 217 fixed on the frame 111. Two fixing rails 216 slidably mounted on the lower part of the first fixing block 215 extend one end toward the second fixing block 217 and are fixed to the second fixing block 217. A pressure bearing seat 218 is slidably mounted on the two fixing rails 216 and placed between the first fixing block 215 and the second fixing block 217. The top of the pressure bearing seat 218 is provided with a holding groove 219 for placing the rotor. The pressure bearing seat 218 is placed between two sets of bearing unloading mechanisms.

[0023] like Figure 1 , 3 As shown, the hollow circular frame 2302 containing the two sets of bearing unloading mechanisms is placed on opposite sides of the first fixing block 215 and the second fixing block 217 and on both sides of the bearing pressure seat 218. When the rotor is transported to the holding groove 219 set on the top of the bearing pressure seat 218, it is as follows: Figure 3 As shown, the rotor is placed in a left-right orientation. At this time, the two ends of the rotor are respectively aligned with the centers of the two bearings inside the two hollow circular frames 2302. When the double-pressure bearing mechanism presses the bearing on the right side into the right end of the rotor, it can simultaneously push the pressure bearing seat 218 to move towards the second fixed block 217 on the fixed rail 216, so that the left end of the rotor can simultaneously extend into the center of the bearing inside the left hollow circular frame 2302. Due to the structural characteristics of the double-pressure bearing mechanism, the pressing of the two bearings and the rotor is synchronous and uniform.

[0024] Example 4 In another embodiment of this utility model, the dual-pressure bearing mechanism includes a connecting block 222 slidably mounted on one end of two fixed rails 216 away from the second fixed block 217, with a first through hole on the upper part of the connecting block 222; a push rod 2231 disposed in the first through hole, wherein one end of the push rod 2231 can pass through the second through hole on the upper part of the first fixed block 215 and be aligned with the hollow circular frame 2302 near the side of the first fixed block 215, and the other end is fixed to the output end of the first telescopic cylinder 220 mounted on the frame 111; fixed on the push rod 2231. The rod 2231 is connected to the first telescopic cylinder 220 by a pressure sensor 221; and a lever 2232 is fixed to one end of the push rod 2231 near the pressure sensor 221; it also includes a transmission rod 224 that passes through the first fixed block 215, the connecting block 222 and the lever 2232, and one end of the transmission rod 224 is fixed to the pressure bearing seat 218, and the other end is fixed to a limit block; a first spring 225 is also sleeved on the outer periphery of the transmission rod 224 between the pressure bearing seat 218 and the first fixed block 215 for resetting the pressure bearing seat 218.

[0025] In this embodiment, one end of the push rod 2231 installed in the second through hole at the upper part of the first fixing block 215 is aligned with Figure 3 The bearing center is located inside the hollow circular frame 2302 on the right side. At the other end of the bearing center, a connecting block 222, a lever 2232, a pressure sensor 221, and the output end of the first telescopic cylinder 220 are fixed in sequence. When the first telescopic cylinder 220 is running, the connecting block 222 and the lever 2232 move to the left on the surface of the fixed rail 216, and the push rod 2231 can be directly pushed. Figure 3 The right bearing is aligned with the right end of the rotor. During the pressing of the right bearing and the right end of the rotor, the pressure bearing seat 218 is pushed to the left, causing the left end of the rotor to extend into the center of the left bearing. During this process, the first spring 225 is stretched. When the push rod 2231 is reset, the first spring 225 drives the pressure bearing seat 218 to reset, so as to realize the assembly process of the two bearings and the rotor. The pressure sensor 221 is a mature existing technology used to control the pressure of the two bearings pressed into both ends of the rotor.

[0026] Example 5 As another embodiment of this utility model, an elastic support mechanism is also provided on the side of the second fixing block 217 away from the first fixing block 215 to improve the uniformity of the assembly of the two bearings and the rotor; the elastic support mechanism includes a mounting block 411 provided on the frame 111; and a third through hole 412 respectively opened on the mounting block 411 and the second fixing block 217, wherein a top block is provided in the third through hole 412 where the second fixing block 217 is located, and one end of the top block extends to the third through hole 412 where the mounting block 411 is located and is fixed between it and the mounting block 411 with a third spring 413, and the other end of the top block is aligned with the hollow circular frame 2302 near the second fixing block 217; the elastic force of the third spring 413 is greater than the compressive force between two adjacent bearings.

[0027] like Figure 1 , 3 As shown in Figure 8, the mounting block 411, which is fixed to the side of the second fixing block 217 away from the first fixing block 215, and the second fixing block 217 are respectively provided with a third through hole 412. The top block provided in the third through hole 412 where the second fixing block 217 is located is connected to the mounting block 411 on the side away from the first fixing block 215. Figure 3 The left hollow circular frame 2302 is aligned, and a third spring 413 is connected between its other end and the third through hole 412 where the mounting block 411 is located. When the first telescopic cylinder 220 drives the push rod 2231 and pushes the bearing inside the hollow circular frame 2302 on the right, when the left end of the rotor extends into the bearing on the left, the top block can adaptively push the bearing on the left under the action of the third spring 413, so as to realize the process of the top block and push rod 2231 clamping the rotor through the two bearings, ensuring the uniformity of the size assembly of the rotor and the two bearings.

[0028] Example 6 In another embodiment of this utility model, a first transfer branch line, a second transfer branch line, and a return belt assembly are sequentially arranged on the frame 111. The first transfer branch line includes a first transfer seat 118 and a first rotary cylinder 119 fixed on the frame 111, wherein a second transfer seat 1191 is arranged on the first rotary cylinder 119. A first transfer clamp is arranged on the frame 111 and placed above the first transfer seat 118 and the second transfer seat 1191. The first transfer clamp includes a first electric slide rail 112, a first electric slider that is slidably installed on the first electric slide rail 112 and can slide left and right, and a second electric slide rail 113 that is cross-shaped with the first electric slide rail 112 is fixed on the first electric slider. The system includes a second electric slider mounted on a second electric slide rail 113 and capable of longitudinal sliding. The second electric slider is provided with an assembly plate 114 and a first gripper 115, a second gripper 116, and a third gripper 117 arranged sequentially along the rotor running direction, with the second gripper 116 being perpendicular to the first gripper 115 and the third gripper 117. The system also includes a third electric slide rail 211 mounted on a frame 111 and capable of left and right movement, with a third electric slider mounted on the third electric slide rail 211; a fourth electric slide rail 212 slidably mounted on the third electric slider; and a fourth electric slider 213 mounted on the fourth electric slide rail 212, with a fourth gripper 214 provided on the fourth electric slider 213. Furthermore, the second transfer branch line includes an assembly block 311 disposed on the side of the frame 111 away from the first transfer seat 118, with a fifth electric slide rail 312 fixed on the assembly block 311; a fifth electric slider 313 disposed on the fifth electric slide rail 312, with a support 314 fixed to the top of the fifth electric slider 313; a sixth electric slide rail 315 disposed on the side wall of the frame 111 and above the assembly block 311, with a sixth electric slider 316 slidably mounted on the sixth electric slide rail 315; a seventh electric slide rail 318 fixed on the sixth electric slider 316, with a seventh electric slider slidably mounted on the seventh electric slide rail 318; a third rotary cylinder 321 fixed on the seventh electric slider, with a fifth gripper 319 disposed at the output end of the third rotary cylinder 321; and a belt track 320 disposed on the front side of the frame 111, with the belt track 320 running towards the first transfer seat 118.

[0029] In this embodiment, the overall operation process is as follows: First, when the external equipment transports several rotors one by one to Figure 1 When the device is in the left position, the first gripper 115, the second gripper 116, and the third gripper 117, which move synchronously at this time, can respectively process the components in an assembly line manner. Figure 1The rotor on the right side is clamped onto the first intermediate rotating seat 118, the rotor on the first intermediate rotating seat 118 is moved to the second intermediate rotating seat 1191, and the rotor on the second intermediate rotating seat 1191 is moved to the holding tank 219. During this process, the first rotary cylinder 119 can change the rotors distributed in the front-to-back direction to the left-to-right direction. Subsequently, the rotor at position 219 of the holding tank undergoes a bearing pressing operation; Subsequently, the fourth gripper 214 of the first transfer branch transfers the rotor bearing on the holding tank 219 to the support 314 of the second transfer branch. Then, the fifth electric slide rail 312 drives the fifth electric slider 313 on it to move to the right, as... Figure 3 As shown; Finally, the fifth gripper 319 transfers the rotor bearing on the support 314 to the surface of the belt track 320. During this process, the rotor bearing changes from a left-right distribution to a front-back distribution and moves towards the belt track. Figure 1 The rotor moves to the left to return to its initial operating position. It is worth noting that the belt track 320 here is a mature existing technology, and its specific structure will not be described in detail.
