[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing processing alignment device. Background Art
[0002] During the machining process of the bearing, in order to ensure the accurate center positioning of its inner ring during the machining process, so as to achieve the alignment of the inner ring with other machining parts, such as the raceway machining tool, a fixture is needed to complete the alignment operation. The common bearing alignment fixture has a three-jaw chuck.
[0003] At present, the overall structure of the existing three-jaw chuck is relatively simple. It is mainly composed of a chuck body and three movable jaws, of which the three movable jaws are always exposed. However, due to the complex environment of the bearing processing workshop and the presence of a large amount of dust, metal chips and other debris, when the three-jaw chuck is idle, the debris in the workshop will fall into the chuck. If this continues for a long time, the friction between the components will increase, thereby affecting the normal operation of the chuck. Therefore, we propose a bearing processing alignment device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] Reference Figure 1-4 , a bearing processing alignment device, including a chuck body 1, a movable claw 13 is arranged on the top of the chuck body 1, the connection method and alignment principle of the chuck body 1 and the movable claw 13 are existing technologies, which will not be described in detail here. A connecting plate 2 is installed on the outside of the chuck body 1, and a connecting groove 3 is provided inside the connecting plate 2. The inner wall of the connecting groove 3 is connected to a threaded rod 4 through a bearing, and two groups of threaded sleeves 5 are provided on the outside of the threaded rod 4. The upper sides of the two groups of threaded sleeves 5 are respectively connected to the protective cover 6. The outer surface of the threaded rod 4 is provided with two groups of external threads with opposite thread directions. Therefore, when the threaded rod 4 rotates, the two groups of threaded sleeves 5 are forced to move closer to or away from each other, thereby realizing the protection of the movable claw 13, or opening the movable claw 13 for processing.
[0023] Further, refer to Figure 4 It can be seen that the end of the threaded rod 4 extends to the outside of the connecting plate 2 and is connected to a rotating bar 7, and the rotating bar 7 is set as a long strip structure. When in use, the rotating bar 7 set as a long strip structure can facilitate the staff to quickly rotate the threaded rod 4, thereby effectively improving the convenience of using this device.
[0024] Further, refer to Figure 1 and Figure 2 It can be seen that scrapers 8 are symmetrically distributed on the left and right ends of the connecting plate 2, and the scraper strips 8 are set to a U-shaped structure. When in use, the scraper strips 8 set with the U-shaped structure can automatically clean up the debris retained above the protective cover 6 when the two sets of protective covers 6 move towards each other.
[0025] Further, refer to Figure 1 and Figure 2 It can be seen that a rubber plate 9 is glued to the inner side of the scraper strip 8, and the lower side of the rubber plate 9 is in contact with the upper surface of the protective cover 6. When in use, the rubber plate 9 made of rubber material can improve the cleaning effect on the top of the protective cover 6.
[0026] Further, refer to Figure 3 It can be seen that the threaded sleeve 5 is set to a rectangular structure, the outer wall of the threaded sleeve 5 is in contact with the inner wall of the connecting groove 3, and a threaded groove adapted to the threaded rod 4 is opened inside the threaded sleeve 5. Since the threaded sleeve 5 is set to a rectangular structure, the threaded sleeve 5 can be guided to effectively prevent the threaded sleeve 5 from idling with the threaded rod 4.
[0027] Further, refer to Figure 3 and Figure 4 It can be seen that a connecting rod 15 is laterally connected to the position of the side of the connecting groove 3 corresponding to the scraper 8, and the end of the connecting rod 15 is connected to a fixed plate 14, a linkage plate 10 is sleeved on the outer side of the connecting rod 15, and a connecting spring 11 is connected to the inner side of the linkage plate 10, and the other end of the connecting spring 11 is connected to the side of the connecting plate 2. When in use, the connection spring 11 and the linkage plate 10 cooperate with each other, which makes it convenient for the staff to remove the damaged scraper 8 in time for replacement.
[0028] Further, refer to Figure 4 It can be seen that the inner side of the linkage plate 10 is connected to the limit block 12, and the bottom end of the scraper 8 is provided with a card slot adapted to the limit block 12. When in use, the staff can pull the linkage plate 10 so that it slides along the outer surface of the connecting rod 15 under force, and pull the connecting spring 11 to deform under force, so that the linkage plate 10 and the limit block 12 can be forced to move and be pulled out from the card slot opened inside the scraper 8 to release the limit on the scraper 8. The mutual cooperation between the limit block 12 and the card slot can ensure the limiting effect of the scraper 8.
[0029] Working principle: When the utility model is in use, the staff can first install the chuck body 1 at a suitable position in the workshop, and then rotate the rotating bar 7 to drive the continuous rotation of the threaded rod 4. At this time, the two groups of threaded sleeves 5 set on the outer side of the threaded rod 4 can be threadedly matched with it, so that the two groups of threaded sleeves 5 can drive the two groups of protective covers 6 to move towards each other, thereby exposing the three groups of movable claws 13. Then the staff can start the chuck body 1, so that the bearing to be processed can be placed between the three groups of movable claws 13 to achieve the alignment of the bearing. After alignment and clamping, the bearing can be processed. After the processing is completed, the staff can reversely rotate the rotating bar 7 so that the threaded sleeve 5 can be threadedly matched with the threaded rod 4 again, so that the two sets of protective covers 6 can be approached to each other, thereby achieving coverage and protection of the chuck body 1 and the movable claw 13. In the process of the protective cover 6 approaching each other, the scraping bar 8 and the rubber plate 9 can cooperate with each other to scrape off the debris attached to the surface of the protective cover 6, thereby eliminating the need for manual cleaning by the staff. The above is the entire working principle of the utility model.
[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
