Description

Technical Field

[0001] The utility model relates to the technical field of turntable bearing processing, in particular to a turntable bearing processing tool. Background Art

[0002] The slewing bearing is a large bearing with a special structure that can withstand large axial loads, radial loads, overturning moments and other combined loads at the same time, and integrates multiple functions such as support, rotation, transmission, and fixation.

[0003] A slewing bearing is usually composed of four major components: an inner ring, an outer ring, rolling elements, and a spacer. Some of the existing processing tools can usually only clamp in a single direction when in use. However, the inner ring needs to be cut and grooved on the outer surface during processing, so it can only be clamped from one side of the inner surface of the inner ring, while the processing of the outer ring is opposite to that of the inner ring. This results in the need for two sets of tools to process the outer ring and the inner ring respectively, which is relatively inconvenient to use. For this reason, we propose a slewing bearing processing tool to solve or improve the above problems. Utility Model Content

One end of the threaded rod 8 is inserted into the support rod and is rotatably connected to the support rod through a bearing. One end of the threaded rod 8 can be supported by the support rod to improve the stability of the threaded rod 8 when it rotates. The second gear 7 is rotatably installed on the inner surface of the workbench 1 through a bearing. The second gear 7 is meshingly connected to the gear ring 11. When the second gear 7 rotates, it will drive the meshing gear ring 11 to rotate. An adjusting handwheel 3 is provided on one side of the surface of the workbench 1. A connecting rod is fixed on the surface of the adjusting handwheel 3. One end of the connecting rod is inserted into the interior of the workbench 1 and fixed to the surface of the second gear 7. When the adjusting handwheel 3 rotates, it will drive the fixed second gear 7 to rotate. The clamping assembly is provided on the top side of the workbench 1, and the number of clamping assemblies is the same as the number of the first gear 6.

[0020] The clamping assembly includes a slider 4 that is slidably installed inside the slide groove 5. A limit block is fixed on the surface of the slider 4. Two groups of limit blocks are symmetrically fixed on the surface of the slider 4. The limit blocks can limit the position of the slider 4 to prevent the slider 4 from escaping from the inside of the slide groove 5. The threaded rod 8 passes through the bottom of the slider 4 and is threadedly connected to the slider 4. When the threaded rod 8 rotates, it will drive the threaded slider 4 to move. A first spring 12 is fixed to the surface of one side of the slider 4. The first spring 12 is symmetrically arranged with two groups on the surface of one side of the slider 4. A second clamping plate 10 is fixed to the top of the first spring 12. When the second clamping plate 10 moves, it will squeeze the first spring 12 to deform the first spring 12. When there is no external force interference, the first spring 12 will push the fixed second clamping plate 10 to move The first spring 12 can buffer the extrusion force applied by the slider 4 to the second clamping plate 10 when the second clamping plate 10 clamps the outer ring of the bearing, thereby avoiding that the pressure applied by the second clamping plate 10 to the outer surface of the bearing outer ring changes rapidly when the surface of the second clamping plate 10 contacts the outer surface of the bearing outer ring, resulting in damage to the outer surface of the bearing outer ring. A toothed limit block is fixed on one side surface of the second clamping plate 10. The toothed limit block can be inserted between the tooth blocks of the bearing outer ring when clamping the bearing outer ring and meshed with the tooth blocks, so that the toothed limit block can limit the position of the bearing outer ring, avoiding the bearing outer ring from rotating itself during processing, thereby improving the clamping effect of the second clamping plate 10 on the bearing outer ring. The second clamping plate 10 is fixed on the other side surface A limit rod is inserted into the interior of the slider 4 and is slidably connected to the slider 4. A limit plate is fixed at one end of the limit rod. The position of the second clamping plate 10 can be limited by the limit plate and the limit sheet to prevent the second clamping plate 10 from detaching from one side of the slider 4 and to prevent the second clamping plate 10 from tilting when moving, thereby improving the stability of the second clamping plate 10 when moving. A second spring 13 is fixed to the surface of the other side of the slider 4. Two groups of second springs 13 are symmetrically fixed on the surface of the slider 4. The first clamping plate 9 is fixed to the top of the second spring 13. When the first clamping plate 9 moves, it will squeeze the second spring 13 to deform the second spring 13. When there is no external force interference, the second spring 13 will push the first clamping plate 9 to move. The second spring 13 can be used to axially contact the first clamping plate 9 When the inner ring of the bearing is clamped, the extrusion force applied by the slider 4 to the first clamping plate 9 is buffered, thereby avoiding that the pressure applied by the first clamping plate 9 to the outer surface of the outer ring of the bearing changes rapidly when the surface of the first clamping plate 9 contacts the outer surface of the outer ring of the bearing, resulting in damage to the outer surface of the outer ring of the bearing. A silicone anti-skid pad is fixed to one side surface of the first clamping plate 9. The anti-skid silicone pad can separate the first clamping plate 9 and the inner ring of the bearing when the first clamping plate 9 clamps the inner ring of the bearing, avoiding the surface of the first clamping plate 9 directly contacting the inner surface of the inner ring of the bearing, thereby avoiding that the first clamping plate 9 causes damage to the inner surface of the inner ring of the bearing during clamping. At the same time, the anti-skid silicone pad can increase the friction between the first clamping plate 9 and the inner surface of the inner ring of the bearing, thereby improving the clamping effect of the first clamping plate 9.A limiting rod is fixed to the other side surface of the first clamping plate 9, and the limiting rod is inserted into the interior of the slider 4 and is slidably connected to the slider 4. A limiting plate is fixed to one end of the limiting rod. The position of the first clamping plate 9 can be limited by the limiting plate and the limiting sheet to prevent the first clamping plate 9 from detaching from one side of the slider 4 and to prevent the first clamping plate 9 from tilting when moving, thereby improving the stability of the first clamping plate 9 when moving.

[0021] Working principle: when the outer ring of the bearing needs to be processed, the adjusting hand wheel 3 can be rotated to make the adjusting hand wheel 3 drive the second gear 7 to rotate. When the second gear 7 rotates, it will drive the gear ring 11 to rotate, so that the gear ring 11 drives several groups of meshing first gears 6 to rotate. When the first gear 6 rotates, it will drive the threaded rod 8 to rotate. When the threaded rod 8 rotates, it will drive the slider 4 to move. When the slider 4 moves, it will drive the fixed first spring 12 to move, so that the first spring 12 drives the fixed second clamping plate 10 to move. The outer surface of the outer ring of the bearing is clamped through the cooperation of several groups of second clamping plates 10, so that it is convenient to process the inner surface of the outer ring of the bearing. When the inner ring of the bearing needs to be processed, the slider 4 can be moved in the opposite direction by reversing the adjusting hand wheel 3, so that the slider 4 drives the fixed second spring 13 to move. When the second spring 13 moves, it will drive the fixed first clamping plate 9 to move, so that the inner surface of the inner ring of the bearing is clamped through several groups of first clamping plates 9, so that it is convenient to process the outer surface of the inner ring of the bearing. There is no need to use two sets of tooling, and it is relatively convenient to use.
