Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a grinding machine for the raceway of the outer ring of a self-aligning roller bearing. Background Technology

[0002] Currently, grinding machines are required when polishing the inner side of the outer ring of self-aligning roller bearings (the inner side of the outer ring has a spherical raceway that needs to be polished). However, traditional grinding machines used for the raceway of self-aligning roller bearings generate a large amount of metal dust during operation. Some of this dust falls directly onto the grinding machine under gravity, causing problems for subsequent cleaning. Furthermore, although traditional grinding machines for the raceway of self-aligning roller bearings have a dust extraction system to absorb and filter some of the airborne metal dust, the outer filter screen of the dust extraction system is prone to clogging after a period of use, requiring manual cleaning and machine shutdown, which is inconvenient. Moreover, traditional grinding machines for the raceway of self-aligning roller bearings make it difficult to simultaneously grind one outer ring while clamping and positioning another, thus reducing grinding efficiency. Summary of the Invention

[0013] Furthermore, when the drive disc is in a rotating state, the drive disc drives the drive column to rotate, and the drive column drives the drive frame and the guide hopper to move back and forth. Beneficial effects

[0014] This invention, through the arrangement of a rotating mechanism, three rotating mechanisms, and three clamping mechanisms, enables the upper self-aligning roller bearing outer ring to be rotated 120 degrees clockwise after grinding. This rotates the upper self-aligning roller bearing outer ring to the lower front side. Then, the grinding wheel position can be adjusted by the adjusting part, and grinding can continue on the inner side of the current upper self-aligning roller bearing outer ring. Simultaneously, a pre-ground self-aligning roller bearing outer ring can be removed from a clamping mechanism at the lower front side, and then the next self-aligning roller bearing outer ring to be ground can be clamped and positioned on the lower front side clamping mechanism. This allows for the simultaneous grinding of one self-aligning roller bearing outer ring while another is being clamped and positioned, thereby improving the grinding efficiency of this grinding machine.

[0015] This invention, through the cooperation of a rotary motor, a first pulley, and a guide section, enables some metal dust to fall into the guide section under gravity during the grinding process. Then, as the rotary motor shaft rotates, the first pulley drives the third pulley via a belt, causing the linkage shaft, first bevel gear, second bevel gear, vertical rotating shaft, and drive disc to rotate. The drive disc then drives the rotating column, which in turn drives the frame and guide hopper to move back and forth. This allows the metal dust that has fallen into the guide section to be discharged from the front outlet of the guide section under the action of shaking and tilting. A collection bucket can be placed below the front of the guide section, thus preventing some metal dust from falling directly onto the grinding machine during grinding and facilitating subsequent cleaning.

[0016] This invention, through the cooperation of a rotating mechanism and a cleaning mechanism, enables the second pulley to rotate while the transverse rotating shaft rotates, thereby rotating the fourth pulley via a belt. This, in turn, causes the transmission shaft to rotate the fourth bevel gear, the third bevel gear, and the circular rotating plate. The circular rotating plate then drives six cleaning brushes to rotate outside the dust filter element, thereby removing the metal dust clogging the filter screen. This allows the filter screen on the dust filter element to be automatically cleaned, eliminating the need for manual cleaning and requiring no machine shutdown, thus greatly improving the convenience of the cleaning process.

The unclogging mechanism 11 is used to clean the outer side of the filter screen on the dust filter element 1006.

[0043] The fourth pulley 1103 is connected to the second pulley 305 via a belt, and the bristles of the six cleaning brushes 1106 are in close contact with the outer side of the filter screen on the dust filter element 1006.

[0044] The specific usage and function of this embodiment: In this invention, when grinding the inner side of the outer ring 8 of the self-aligning roller bearing, the outer ring 8 of the self-aligning roller bearing is first clamped and positioned on three clamping mechanisms 7. During clamping, the outer ring 8 of the self-aligning roller bearing is placed between two anti-slip clamping blocks 704. Then, by manually rotating the clamping screw 702, the two clamping plates 703 move simultaneously in opposite directions with the two anti-slip clamping blocks 704 under the action of the two reverse threads on the outside of the clamping screw 702, thereby clamping and positioning the outer ring 8 of the self-aligning roller bearing.

[0045] Then, the telescopic rod of the second electric cylinder 404 retracts, thereby moving the L-shaped support plate 401, the first electric cylinder 402, the lifting slide plate 403, the grinding motor 5, and the grinding wheel 501 to the right, so that the grinding wheel 501 enters the inner side of the outer ring 8 of the upper self-aligning roller bearing. Then, the telescopic rod of the first electric cylinder 402 extends upward, thereby moving the lifting slide plate 403, the grinding motor 5, and the grinding wheel 501 upward, so that the grinding wheel 501 contacts the upper side of the inner circumferential surface of the outer ring 8 of the upper self-aligning roller bearing. Then, the grinding motor 5 is started, so that the rotating shaft of the grinding motor 5 rotates the grinding wheel 501, thereby starting the grinding work on the upper side of the inner circumferential surface of the outer ring 8 of the upper self-aligning roller bearing.

[0046] After the outer ring 8 of the upper self-aligning roller bearing is ground, the telescopic rod of the first electric cylinder 402 is retracted downwards, and the telescopic rod of the second electric cylinder 404 is extended to the right, thus moving the grinding wheel 501 out from the inside of the outer ring 8 of the upper self-aligning roller bearing. Then, the rotary motor 303 is started, causing the rotating shaft of the rotary motor 303, the first worm gear, and the first worm wheel to rotate the transverse rotating shaft 302 120 degrees clockwise. Then, the transverse rotating shaft 302 rotates the rotating plate 301 120 degrees clockwise, thereby rotating the three rotating mechanisms 6, the three clamping mechanisms 7, and the three self-aligning roller bearing outer rings 8 120 degrees clockwise, thus moving the upper self-aligning roller bearing outer ring 8 out of the inner ring 8. One self-aligning roller bearing outer ring 8 is rotated to the lower front side. Then, the position of the grinding wheel 501 can be adjusted by the adjustment part 4. The grinding work on the inner side of the current upper self-aligning roller bearing outer ring 8 can continue. While the current upper self-aligning roller bearing outer ring 8 is being ground, the self-aligning roller bearing outer ring 8 that has been ground in advance can be removed from the front lower clamping mechanism 7. Then, the next self-aligning roller bearing outer ring 8 to be ground can be clamped and positioned on the front lower clamping mechanism 7. This allows the other self-aligning roller bearing outer ring 8 to be ground to be clamped and positioned in advance while one self-aligning roller bearing outer ring 8 is being ground, thereby improving the grinding efficiency of this grinding machine.

[0047] Furthermore, during the grinding process, the dust extraction mechanism 10 absorbs the metal dust floating in the air. Then, some of the metal dust will fall into the guide section 9 under the action of gravity. During the rotation of the rotating motor 303 shaft, the first pulley 304 drives the third pulley 903 to rotate through the belt, thereby causing the linkage shaft 902, the first bevel gear, the second bevel gear, the vertical rotating shaft 906, and the drive disk 907 to rotate. Then, the drive disk 907 drives the drive column 908 to rotate, and the drive column 908 drives the drive frame 905 and the guide hopper 901 to move back and forth. This allows the metal dust that falls into the guide section 9 to be discharged from the front outlet of the guide section 9 under the action of shaking and the tilting action of the guide section 9. A collection bucket can be placed below the front of the guide section 9, thereby avoiding the phenomenon that some metal dust will fall directly onto the grinding machine during the grinding process, thus making subsequent cleaning work more convenient.

[0048] While the transverse rotating shaft 302 rotates, the second pulley 305 drives the fourth pulley 1103 to rotate via a belt, thereby causing the transmission shaft 1102 to rotate along with the fourth bevel gear, the third bevel gear, and the circular rotating plate 1101. Then, the circular rotating plate 1101 drives six cleaning brushes 1106 to rotate outside the dust filter element 1006, thereby removing the metal dust clogging the filter screen on the dust filter element 1006. This allows the filter screen on the dust filter element 1006 to be automatically cleaned, eliminating the need for manual cleaning and requiring no machine shutdown during cleaning, thus greatly improving the convenience of the cleaning process.
