[0036] Example 1

[0037] Reference Figures 1 to 8 , which is the first embodiment of the present invention, and provides a convenient and efficient bearing seat installation and alignment device, including an installation mechanism 100, a bearing seat 200 and a rotor shaft 300;

[0038] The mounting mechanism 100 includes a strong magnetic block 101, a mounting frame 102 fixedly connected to the top of the strong magnetic block 101, and a dial indicator 103 arranged inside the mounting frame 102. A trigger rod 104 is slidably connected inside the strong magnetic block 101.

[0039] Specifically, the mating surface between the strong magnetic block 101 and the rotor shaft 300 is configured as an arc surface, and the arc surface of the strong magnetic block 101 is provided with an embedding groove 101 a.

[0040] Furthermore, an inner cavity 102 a is provided inside the mounting frame 102 , and a return spring 102 b is provided inside the inner cavity 102 a .

[0041] Preferably, the top of the mounting frame 102 is fixedly connected with a protective tube 102c, a slide groove 102d is provided between the protective tube 102c and one side of the mounting frame 102, a positioning hole 102e is provided on the other side of the slide groove 102d of the mounting frame 102, and the outer side of the mounting frame 102 is fixedly connected with glass 102f.

[0042] It should be noted that a rotating shaft 103a is fixedly connected to the back of the dial gauge 103, a gear 103b is fixedly connected to the outer side of the rotating shaft 103a, and a round hole 103c is opened on the side away from the test head of the dial gauge 103;

[0043] The dial indicator 103 is rotatably connected to the inside of the mounting frame 102 via a rotating shaft 103a, and the front of the dial indicator 103 faces the glass 102f.

[0044] Preferably, the bottom end of the trigger rod 104 is fixedly connected with a pressing block 104a, the top end of the trigger rod 104 is fixedly connected with a sliding block 104b, and the top end of the sliding block 104b is fixedly connected with a rack 104c;

[0045] The rack 104c is meshed with the gear 103b, the return spring 102b is sleeved on the outside of the trigger rod 104, and one end of the return spring 102b is connected to the bottom end of the pressure block 104a, and the other end is connected to the inner cavity 102a.

[0046] Furthermore, the bottom end of the bearing seat 200 is fixedly connected to the base 201, the top end of the bearing seat 200 is fixedly connected to the hook 202, the two ends of the bearing seat 200 are bolted with bearing covers 203, and the outer surface of the bearing cover 203 is provided with a test surface 204.

[0047] When in use, it is only necessary to fit the arc surface of the strong magnetic block 101 to the outer surface of the rotor shaft 300. Under the magnetic attraction of the strong magnetic block 101, it can be installed on the outer side of the rotor shaft 300. At the same time, after the strong magnetic block 101 is adsorbed, it will drive the pressure block 104a to slide completely into the inside of the groove 101a under the action of extrusion, and drive the slider 104b at the top of the trigger rod 104 to slide inside the inner cavity 102a through the pressure block 104a, and finally drive the rack 104c at the top of the slider 104b to slide, and the sliding rack 104c can drive the gear 103b to rotate, and the gear 103b can cooperate with the rotating shaft 103a to drive the dial indicator 103 to rotate, and finally drive the test head of the dial indicator 103 to vertically touch the test surface 204 of the bearing cover 203, and then read each point through the alignment method.

[0048] The device adopts an integrated design and a strong magnetic block 101 adsorption installation method, which is not only convenient and quick to install as a whole, but also requires the strong magnetic block 101 to be located at a specified position and adsorbed on the outside of the rotor shaft 300 to quickly complete the installation of the dial indicator 103; at the same time, during normal storage, the test head of the rotor shaft 300 is located inside the protective tube 102c, so that the dial indicator 103 can be effectively protected during the storage process, which realizes both quick installation and portable operation, and also realizes effective storage of the dial indicator 103. Combined with the alignment method, the efficiency and accuracy of the alignment of the bearing seat 200 are improved as a whole.

[0049] In summary, the device can not only realize the quick installation of the dial indicator 103 through magnetic attraction and integrated design, but also realize the effective protection of the dial indicator 103 when the dial indicator 103 is not in use. Compared with the traditional operation method of first installing the support frame and then installing the dial indicator 103 on the support frame, this installation method is convenient to operate.

[0050] Example 2

[0051] Reference Figures 1 to 8 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides that a limit spring 103c-1 is fixedly connected to the inside of the circular hole 103c, and one end of the limit spring 103c-1 is fixedly connected to a positioning block 103c-2.

[0052] When the dial indicator 103 rotates horizontally to make the test head of the dial indicator 103 vertically fit the test surface 204 of the bearing cover 203, the circular hole 103c on the outside of the dial indicator 103 will be driven to be coaxial with the positioning hole 102e, and under the elasticity of the limit spring 103c-1, the positioning block 103c-2 will be driven to slide and engage with the positioning hole 102e. Through the engagement of the positioning block 103c-2 with the positioning hole 102e, the dial indicator 103 can be completely limited. When the dial indicator 103 is rotated to perform a comprehensive measurement of the test surface 204 of the bearing cover 203, it can be avoided that the dial indicator 103 is excessively squeezed due to the tilt of the bearing seat 200, driving the dial indicator 103 to rotate in the opposite direction, driving the rack 104c to reset and slide, causing the pressure block 104a to squeeze the rotor shaft 300 and cause the connection to become loose, thereby ensuring the stability of the dial indicator 103 after installation and the accuracy of data measurement.

[0053] At the same time, through the clamping connection between the positioning block 103c-2 and the positioning hole 102e, the elastic potential energy generated by the limit spring 103c-1 can be completely limited, so as to avoid the reaction force generated by the trigger rod 104 driven by the limit spring 103c-1 after the strong magnetic block 101 is adsorbed on the rotor shaft 300, which affects the stability of the overall installation of the equipment. In this way, while ensuring the quick installation of the dial indicator 103, the stability of the dial indicator 103 after installation can be effectively guaranteed, and the accuracy of data measurement can be ensured.

[0054] When disassembly is required, the operator holds the mounting frame 102 and squeezes the positioning block 103c-2 with his fingers, causing the positioning block 103c-2 to squeeze the limit spring 103c-1 and return to the inside of the circular hole 103c, and then pulls the mounting frame 102 to separate the strong magnetic block 101 from the rotor shaft 300. At this time, the elasticity of the reset spring 102b will drive the trigger rod 104 to reset, thereby storing the dial indicator 103 to ensure effective protection of the dial indicator 103 during storage.

[0055] In summary, when the equipment installs the dial indicator 103, it can not only achieve convenient and quick installation, but also ensure the stability of the dial indicator 103 after installation, ensure the accuracy of data measurement, and can also realize the quick disassembly of the dial indicator 103, and ensure the effective storage and protection of the dial indicator 103; combined with the simple and easy-to-understand alignment method, the overall alignment efficiency and accuracy of the bearing seat 200 are improved.

[0056] Example 3

[0057] Reference Figures 1 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an alignment method, including a convenient and efficient bearing seat installation and alignment device, and the following operating steps,

[0058] Correct the horizontality of the rotor shaft: Use a spirit level to correct the horizontality of the rotor shaft by adjusting the bottom adjustment pads of the bearing seats at both ends until the horizontality is qualified;

[0059] Bearing seat alignment: Based on the calibrated rotor shaft, set the mounting mechanism on the side shaft of the bearing seat, and point the dial indicator measuring head vertically to the test surface set on the end face of the bearing seat, rotate the shaft to record the dial indicator reading; judge whether the reading is consistent, and adjust the specific position of the bearing seat accordingly until the alignment is completed;

[0060] Verification: After completing the above steps, tighten all the anchor bolts of the bearing seat, then rotate the shaft to record the dial indicator data, and confirm that the four-point data are consistent. If there is any deviation, readjust it.

[0061] Specifically, select four-point vertical and horizontal readings, and adjust the adjustment pad under the bearing seat according to the readings to make the four-point data consistent.

[0062] In summary, first, use a spirit level to correct the horizontality of the rotor shaft, which involves adjusting the adjustment pads at the bottom of the bearing seat until the required horizontality standard is reached. Next, the bearing seat is accurately aligned. This step uses the calibrated and positioned rotor shaft as a reference, sets a mounting mechanism on the shaft next to the bearing seat, and uses a dial indicator to measure. By pointing the test surface vertically to the end face of the bearing seat, rotate the shaft to record the readings of the dial indicator, which must be obtained at four vertical and horizontal points. Based on these readings, adjust the adjustment pads under the bearing seat to ensure data consistency at the four points to complete the alignment of the bearing seat.

[0063] After the initial alignment is completed, the review step is carried out. At this time, all the anchor bolts of the bearing seat will be tightened, and the shaft will be rotated again to record the data of the dial indicator. If the four-point data are consistent, it means that the alignment is accurate; if there is a deviation, it needs to be readjusted. This series of correction and alignment processes ensures the correct positioning of the rotor shaft and the precise alignment of the bearing seat, which is a key link to ensure the efficient, stable operation and long-term reliability of the equipment.
