Description

Technical Field

[0001] This utility model relates to the field of turntable bearing technology, specifically a tooling for replacing turntable bearings. Background Technology

[0002] Slewing bearings are large bearings with a special structure capable of simultaneously withstanding large axial loads, radial loads, and overturning moments. They integrate multiple functions such as support, rotation, transmission, and fixation. Slewing bearings typically consist of four main components: an inner ring, an outer ring, rolling elements, and spacers. Because the core component uses a slewing bearing, it can simultaneously withstand axial and radial forces. While there are many types, their basic structural components are largely similar.

[0003] In order to ensure the stability of rotation in large equipment, turntable bearings are used. When the turntable bearing malfunctions, it needs to be replaced. Due to the large size and complex structure of the turntable bearing, the operation is quite cumbersome when replacing it. Therefore, we provide a tooling for turntable bearing replacement to solve the above problems. Utility Model Content

The support sleeve 202 is positioned by the sliding groove 203 and the sliding block 204, thereby improving the stability of the support sleeve 202 sliding on the surface of the support column 201.

[0025] A positioning toothed plate 205 is fixedly connected to the middle of the support column 201. A positioning toothed block 206 that meshes with the positioning toothed plate 205 slides inside the support sleeve 202. An adjusting bolt 207 for adjusting the positioning toothed block 206 is threadedly connected to the top of the support sleeve 202. The adjusting bolt 207 is rotatably connected to the positioning toothed block 206. By the meshing of the positioning toothed block 206 and the positioning toothed plate 205, the support sleeve 202 and the support column 201 are fixedly connected together, thereby fixing the position of the worktable 1 and improving the stability of the operation of the worktable 1. By rotating the adjusting bolt 207, the meshing of the adjusting bolt 207 and the positioning toothed block 206 is controlled, thereby improving the stability and convenience of adjusting the position of the support sleeve 202.

[0026] Please refer to it again. Figure 1 and Figure 3 A power mechanism 3 is provided in the middle of the workbench 1. The power mechanism 3 includes a lifting plate 301, a mounting ring 303 and an adjusting plate 306.

[0028] The second electric push rod 305 is fixedly installed inside the mounting ring 303 by bolts, and the output end of the second electric push rod 305 is fixedly connected to the adjusting plate 306. The second electric push rod 305 controls the movement of the adjusting plate 306, and the adjusting arm 402 drives the clamping arm 401 to move, so that the fixing claw 403 grips and fixes the turntable bearing.

[0029] The second electric push rod 305 is provided with a connecting rod 302 on its outside. Both ends of the connecting rod 302 are fixedly connected to the lifting plate 301 and the mounting ring 303 by bolts. The connecting rod 302 fixes the lifting plate 301 and the mounting ring 303 together. The bolt connection facilitates the replacement and maintenance of the second electric push rod 305, improving the convenience of device maintenance.

[0030] A controller is fixedly connected to the surface of the workbench 1, and the first electric push rod 304 and the second electric push rod 305 are both electrically connected to the controller. The first electric push rod 304 and the second electric push rod 305 are both existing technologies, and their detailed parameters and models will not be described in detail in this application.

[0031] Please refer to it again. Figure 1 and Figure 4 The mounting ring 303 is provided with a circumferentially arranged clamping mechanism 4. The clamping mechanism 4 includes a clamping arm 401 and an adjusting arm 402. The two ends of the clamping arm 401 are respectively hinged to the adjusting plate 306 and the adjusting arm 402. The bottom of the adjusting arm 402 is fixedly connected to a fixing claw 403. By moving the adjusting plate 306, the adjusting arm 402 drives the clamping arm 401 to move, thereby fixing or clamping the inner or outer ring of the turntable bearing, improving the stability of the turntable bearing clamping and fixing. The fixing claw 403 improves the stability of the clamping between the adjusting arm 402 and the turntable bearing.

[0032] The top of the adjusting arm 402 is hinged to the mounting ring 303. Rubber pads 404 are installed on both sides of the fixing claw 403. The rubber pads 404 are welded to the fixing claw 403. A reinforcing rod 405 is provided on the surface of the adjusting arm 402. The rubber pads 404 increase the friction between the fixing claw 403 and the turntable bearing, thereby improving the stability of the fixing claw 403 in fixing the turntable bearing. The reinforcing rod 405 fixes the adjusting arm 402, thereby improving the stability of the adjusting arm 402 in gripping the turntable bearing.

[0033] A sliding rod 407 is fixedly connected to the surface of the mounting ring 303. The sliding ring 406 of the limit adjustment plate 306 slides on the surface of the sliding rod 407, and the sliding ring 406 is fixedly connected to the adjustment plate 306. The adjustment plate 306 is fixed by the sliding rod 407 and the adjustment plate 306, thereby improving the stability of the vertical movement of the adjustment plate 306.

[0034] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0035] In use, this utility model works as follows: The support sleeve 202 is fixedly installed on the surface of the equipment whose turntable bearing is to be replaced using the fixing plate 208 and bolts. First, loosen the adjusting bolt 207 and adjust the worktable 1 to a suitable height. By rotating the adjusting bolt 207, the adjusting bolt 207 engages with the positioning tooth block 206, fixing the support sleeve 202 to the support column 201. The second electric push rod 305 is activated to control the movement of the adjusting plate 306, and the adjusting arm 402 drives the clamping arm 401 to move, causing the fixing claw 403 to grip the outer or inner ring of the turntable bearing. The first electric push rod 304 controls the movement of the lifting plate 301 to disassemble the turntable bearing. When a new turntable bearing needs to be installed, the new turntable bearing is placed in the corresponding position. The first electric push rod 304 controls the lifting plate 301, causing the fixing claw 403 to push the turntable bearing to move, completing the turntable bearing installation. This device reduces the difficulty of disassembling and installing turntable bearings and improves the efficiency of turntable bearing replacement.
