Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Example 1
[0025] like Figs. 1-2 As shown, a bearing scraper roller fixture is used to ensure that the inner and outer diameters of the inner ring or the outer ring of the scraper roller bearing to be ground are on the same axis. The fixture's structural design includes a large-end bearing limiting head 1, one end of which has a large-end limiting lock nut hole 11 for installing a connecting lock nut to limit the scraper roller bearing on the large-end bearing limiting head 1; the other end of the large-end bearing limiting head 1 is connected to a small-end bearing limiting head 2, one end of which has a small-end limiting lock nut hole 21 for installing a connecting lock nut to limit the scraper roller bearing on the small-end bearing limiting head 2.
[0026] The large end 1 of the oil scraper roller fixture can limit the inner diameter of the oil scraper roller bearing that needs to be ground. At the same time, the small end 2 of the oil scraper roller fixture can also limit the inner diameter of the oil scraper roller bearing that needs to be ground, only the diameters of the oil scraper roller bearings limited by the two are different. Alternatively, the large end 1 of the oil scraper roller fixture can limit the outer ring of the same oil scraper roller bearing, while the small end 2 of the oil scraper roller fixture can limit the inner ring of the same oil scraper roller bearing. In this way, the inner and outer diameters of the oil scraper roller bearing are kept on the same axis by the bearing scraper roller fixture, thereby ensuring the assembly quality of the bearing that needs to be ground.
[0027] Example 2
[0028] Based on example 1, the oil scraping roller bearing limiting small head 2 is connected with the oil scraping roller bearing limiting large head 1 through the connecting shaft 3, and the end of the connecting shaft 3 away from the oil scraping roller bearing limiting small head 2 is used to connect with the oil scraping roller bearing limiting large head 1. The oil scraping roller bearing limiting small head 2 and the oil scraping roller bearing limiting large head 1 are connected through the connecting shaft 3, and the inner and outer diameters of the oil scraping roller bearing temporarily limited and stabilized on the oil scraping roller bearing limiting small head 2 and the inner and outer diameters of the oil scraping roller bearing temporarily limited and stabilized on the oil scraping roller bearing limiting large head 1 are on the same axis, so that the inner and outer diameters of the oil scraping roller bearing (or the inner and outer diameters of the inner ring and the outer ring of the same oil scraping roller bearing) are on the same axis during grinding, and the quality of the assembled oil scraping roller bearing is ensured.
[0029] Meanwhile, the connecting shaft 3 is sleeved with a sliding sleeve 31, one end of the sliding sleeve 31 is used to abut against the end face of the oil scraping roller bearing limited on one end of the oil scraping roller bearing limiting large head 1, and the other end of the sliding sleeve 31 close to the oil scraping roller bearing limiting small head 2 is provided with a movable structure for slidingly limiting the sliding sleeve 31.
[0030] The movable structure includes a movable limiting shaft sleeve 32, which is movably sleeved on the connecting shaft 3. The end of the sliding sleeve 31 close to the movable limiting shaft sleeve 32 is provided with a limiting groove, and the gap between the limiting groove and the outer wall of the connecting shaft 3 is used for the end of the movable limiting shaft sleeve 32 close to the sliding sleeve 31 to enter. The end of the movable limiting shaft sleeve 32 close to the sliding sleeve 31 is movably entered into the gap between the limiting groove of the sliding sleeve 31 and the outer wall of the connecting shaft 3, and abuts against the bottom end of the limiting groove of the sliding sleeve 31, so as to drive the sliding sleeve 31 to slide along the connecting shaft 3. The sliding sleeve 31 abuts against the end face of the oil scraping roller bearing which is temporarily limited on the oil scraping roller bearing limiting large head 1 through the locking nut, and the oil scraping roller bearing on this side is limited and stabilized on the oil scraping roller bearing limiting large head 1, so as to ensure that the inner and outer diameters of the oil scraping roller bearing are on the same axis.
[0031] Example 3
[0032] In the example, the end of the movable limiting shaft sleeve 32 close to the oil scraping roller bearing limiting small head 2 is provided with a limiting nut 33. The limiting nut 33 is threadedly connected to the end of the connecting shaft 3 close to the oil scraping roller bearing limiting small head 2, and the end of the limiting nut 33 close to the oil scraping roller bearing limiting small head 2 is movable along the connecting shaft 3, and is used to limit the oil scraping roller bearing on the oil scraping roller bearing limiting small head 2. Furthermore, the end of the movable limiting shaft sleeve 32 close to the limiting nut 33 is connected with a limiting disc, and the end of the limiting disc close to the limiting nut 33 is used to abut against the limiting nut 33 to limit and resist the limiting nut 33.
[0033] By sliding adjustment of the limiting nut 33, the end face of the oil scraper roller bearing temporarily positioned on the oil scraper roller bearing limiting small head 2 by the locking nut can be realized, and the oil scraper roller bearing on this side is limited and stabilized on the oil scraper roller bearing limiting small head 2, thereby ensuring that the inner and outer diameters of the oil scraper roller bearing are on the same axis. And when adjusting, the limiting disc connected to the end of the movable limiting sleeve 32 close to the limiting nut 33 and the limiting nut 33 can realize mutual abutment limiting, avoiding the sliding "too much" of the two, which will affect the limiting of the oil scraper roller bearing on each side.
[0034] Finally, through the bearing oil scraper roller tool, the inner and outer diameters of the inner ring of the oil scraper roller bearing that needs to be ground or the inner and outer diameters of the outer ring of the oil scraper roller bearing can be on the same axis, so that the ground oil scraper roller bearing inner ring and the oil scraper roller bearing outer ring can better adapt, ensuring the quality of the assembled oil scraper roller bearing.
