Description

Technical Field

[0001] This utility model relates to the field of industrial technology, and in particular to a device for mounting generator bearings. Background Technology

[0002] Generator bearing installation refers to the process of correctly assembling the bearing onto the generator rotor shaft and related support structures. The bearing is a key component in the generator, and its main function is to support the generator rotor so that it can rotate smoothly and with low friction, and to bear the weight of the rotor and various forces generated during operation.

[0003] Patent CN222552710U discloses a spherical plain bearing installation mechanism. It includes a mounting base and a hydraulic cylinder. The mounting base has a fixed limiting sleeve inside, with an oil reservoir at the top of the inner wall of the limiting sleeve and another oil reservoir at the bottom of the inner wall. The top of the second oil reservoir is connected to a channel, and an oil inlet is located at one end of the top wall of the limiting sleeve. When using this patent, the hydraulic cylinder is activated, extending and pressing down the pressure block and upper mold, pressing the inner ring of the spherical plain bearing into the outer ring, thus completing the installation. However, this existing patent still has some shortcomings in practical use. Because the pressure block in the existing patent is fixed to the bottom of the hydraulic cylinder, it is not easy to disassemble. Different bearing models require different pressure block shapes, sizes, and contact surface curvature parameters for installation. If the bearing and pressure block are not compatible, uneven force during installation can lead to bearing tilting, deformation, and damage.

[0004] Therefore, there is a need for a generator bearing mounting device that facilitates the replacement of pressure blocks. Utility Model Content

[0005] To overcome the shortcomings of existing patents where the pressure block is fixed to the bottom of the hydraulic cylinder, making disassembly inconvenient, and the fact that different bearing models require different pressure block shapes, sizes, contact surface curvatures, and other parameters for pressing, and that uneven force distribution during pressing can lead to bearing tilting, deformation, and damage when the bearing and pressure block are not compatible, this utility model provides a generator bearing installation device that facilitates pressure block replacement.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a generator bearing installation device, comprising a worktable, a fixed base, a cylinder, a slide block, and a pressure plate. The fixed base is fixedly connected to the worktable, the cylinder is mounted on the fixed base, the slide block is mounted on the cylinder's telescopic rod, and the pressure plate is inserted into the slide block. The device also includes an installation plate, sliding rods, locking blocks, elastic elements, and mounting blocks. The installation plate is fixedly connected to the slide block, two sliding rods are slidably mounted on the installation plate, locking blocks are fixedly connected to the sliding rods, two mounting blocks are fixedly connected to the pressure plate, and elastic elements are sleeved on the sliding rods, with both ends of the elastic elements connected to the locking blocks and the installation plate, respectively.

[0007] Preferably, the device also includes a fixed plate, an airbag, a connecting pipe, an air tank, and an air pump. The fixed plate is fixedly connected to the worktable, and the airbag is installed inside the fixed plate. Two air tanks are fixedly connected to the worktable, and an air pump is installed on the air tank. A connecting pipe connects the air pump to the airbag.

[0008] Preferably, the device also includes a camera and two warning devices. The camera is mounted on the mounting plate, and the warning devices are electrically connected to the camera.

[0009] As a preferred option, the workbench is equipped with four feet.

[0010] Preferably, the card block is rectangular.

[0011] Preferably, two guide rods are fixedly connected to the slide.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By inserting the pressure plate of the corresponding size into the slide block, and aligning the mounting block on the pressure plate with the locking block on the mounting plate, after alignment, the slide rod is released, and the elastic element rebounds and drives the slide rod and the locking block to move inward, so that the locking block is locked into the mounting block on the pressure plate, thereby realizing the quick locking and unlocking of the pressure plate, and thus enabling the pressure plate of the corresponding size to be replaced according to the generator and bearing, ensuring that the bearing is subjected to uniform force.

[0013] 2. By starting the air pump, the air pump draws gas from the air tank into the air bag through the connecting pipe, causing the air bag to expand and fix the generator in place, preventing the generator from shifting position during press-fitting.

[0014] 3. The bearing installation position and pressing process are monitored in real time by a camera. When an installation deviation or abnormality is detected, an alarm is triggered by an electrical signal to remind the operator to make timely adjustments, thereby further ensuring installation accuracy and quality.

Detailed Implementation

[0021] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0022] Example 1: A device for installing generator bearings, see reference. Figures 1-5 As shown, the device includes a worktable 1, a fixed base 2, a cylinder 3, a slide 4, and a pressure plate 5. The fixed base 2 is welded to the rear top of the worktable 1. The cylinder 3 is bolted to the upper part of the fixed base 2. The slide 4 is mounted on the telescopic rod of the cylinder 3. The pressure plate 5 is inserted into the slide 4. The device also includes a mounting plate 11, a sliding rod 12, a locking block 13, an elastic element 14, and a mounting block 15. The mounting plate 11 is fixedly connected to the lower part of the slide 4. The sliding rod 12 is slidably mounted on both the left and right sides of the mounting plate 11. The locking block 13 is welded to the end of the sliding rod 12. The mounting block 15 is fixedly connected to both the left and right sides of the pressure plate 5. The locking block 13 is inserted into the adjacent mounting block 15. The elastic element 14 is sleeved on the sliding rod 12. The two ends of the elastic element 14 are connected to the locking block 13 and the mounting plate 11, respectively.

[0023] See Figures 1-3 and Figure 5 As shown, four foot pads are evenly spaced at the bottom of the workbench 1.

[0024] See Figure 4 As shown, the locking block 13 is rectangular, which facilitates its insertion into the mounting block 15.

[0025] See Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, two guide rods are fixedly connected to the slide 4, and the guide rods slide on the fixed seat 2.

[0026] When using this device, place the generator on the workbench 1, below the cylinder 3, and pre-insert the generator bearing into the corresponding position. Then, pull the slide rod 12 outward, causing the sliding rod 12 to move the locking block 13 outward and compress the elastic element 14. The elastic element 14 is then compressed. Next, insert the pressure plate 5 of the corresponding size onto the slide block 4, aligning the mounting block 15 on the pressure plate 5 with the locking block 13 on the mounting plate 11. After alignment, release the slide rod 12, and the elastic element 14 will rebound, causing the slide rod 12 and locking block 13 to move inward, so that the locking block 13 engages with the mounting block 15 on the pressure plate 5, achieving quick locking and unlocking of the pressure plate 5. This allows for the replacement of the pressure plate 5 of the corresponding size according to the generator and bearing, ensuring uniform bearing force. Then, start the cylinder 3, and the telescopic rod of the cylinder 3 drives the slide block 4 to move up and down. The slide rod 12 drives the pressure plate 5 to move downward to complete the bearing pressing operation.

[0027] Example 2: Based on Example 1, refer to Figure 1 and Figure 3 As shown, it also includes a fixing plate 6, an airbag 7, a connecting pipe 8, an air tank 9, and an air pump 10. The fixing plate 6 is fixedly connected to the top of the workbench 1. The fixing plate 6 is located below the pressure plate 5. An airbag 7 is provided on the inner side of the fixing plate 6. Air tanks 9 are fixedly connected symmetrically to the top of the workbench 1. An air pump 10 is provided on the air tank 9 by means of bolt connection. A connecting pipe 8 connects the air pump 10 and the airbag 7.

[0028] When the generator is placed on the workbench 1, the generator is positioned in the center of the airbag 7. Then, the air pump 10 is started. The air pump 10 draws the gas from the air tank 9 into the airbag 7 through the connecting pipe 8, causing the airbag 7 to expand and fix the generator in place. This prevents the generator from shifting during press-fitting and ensures installation accuracy.

[0029] See Figure 1 and Figure 5 As shown, it also includes a camera 16 and an alarm 17. The camera 16 is installed on the top of the fixing plate 6, and the alarm 17 is symmetrically installed on the left and right sides of the top of the fixing plate 6. The alarm 17 is electrically connected to the camera 16.

[0030] During the press-fitting operation, the camera 16 monitors the bearing installation position and press-fitting process in real time. If an installation deviation or abnormality is detected, the alarm 17 is triggered by an electrical signal to remind the operator to make timely adjustments, thereby further ensuring installation accuracy and quality.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
