[0019] Example
[0020] like Figures 1 to 4 As shown, the utility model provides a technical solution, a CNC lathe chuck for bearing processing, comprising: a connecting seat 1, a tightening adjustment mechanism is installed on the connecting seat 1, an adjusting seat 4 is installed on the tightening adjustment mechanism, one side of the adjusting seat 4 is clamped with an arc sleeve 2 through the mounting mechanism, the mounting mechanism comprises a pulling assembly and an extrusion assembly, a positioning sleeve 3 is installed on the top of the connecting seat 1, the mounting mechanism is installed on the tightening adjustment mechanism, the extrusion assembly is used to assemble arc sleeves 2 of different sizes, and the pulling assembly is used to remove the assembled arc sleeve 2. When in use, the chuck can be pushed into the push groove by aligning the push plate 5 on the arc sleeve 2, and it can be locked on the adjusting seat 4 by using the extrusion assembly. On the contrary, the pull ring 12 is buckled to drive the movable rod 11 to move, so that the arc sleeve 2 can be removed and replaced with an arc sleeve 2 of corresponding size. The structure is simple and the operation is convenient. The arc sleeve 2 of corresponding size can be quickly replaced by the pressing and pulling operation, which increases the practicality of the device.
[0021] The extrusion assembly includes a push plate 5 installed on one side of the arc sleeve 2, a push groove that is engaged with the push plate 5 is opened on one side of the adjusting seat 4, a rebound groove 6 is opened on one side of the push groove inside the adjusting seat 4, the inner side of the rebound groove 6 is connected with the inner side of the push groove, and a rebound plate 7 is slidably connected to the inner side of the rebound groove 6. The contact ends of the rebound plate 7 and the push plate 5 are both provided with slopes 9 that fit each other, and springs 8 are installed between the two ends of one side of the rebound plate 7 and the inner wall of the rebound groove 6. The cross-section of the rebound plate 7 is T-shaped, and the cross-section of the push plate 5 is L-shaped. First, the push plate 5 on the arc sleeve 2 is aligned with the push groove and pushed in. The push plate 5 is against one end of the rebound plate 7, and the two sets of slopes 9 are in contact, forcing the rebound plate 7 to drive the two sets of springs 8 to retract. After the push plate 5 is fully pushed in, the rebound plate 7 is no longer obstructed, and it will pop out by itself to resist one end of the push plate 5 to complete the positioning installation.
[0022] The pulling assembly includes a movable groove 10 opened at one end of the top of the adjustment seat 4, and a movable rod 11 is installed on one side of the rebound plate 7 between the two groups of springs 8. The movable rod 11 extends to one end of the inner side of the movable groove 10 and is rotatably connected to a pull ring 12. A positioning rod 13 is installed on the top of the adjustment seat 4 on one side of the movable groove 10. Then, the pull ring 12 is buckled to drive the movable rod 11 to move, so that the rebound plate 7 moves again to squeeze the spring 8. After the rebound plate 7 completely enters the rebound groove 6, the pull ring 12 is offset and rotated to be hung on the positioning rod 13 for positioning. At this time, the arc sleeve 2 can be removed.
[0023] The tightening adjustment component includes two groups of staggered and non-coplanar adjustment grooves 14, the inner side of the adjustment grooves 14 is rotatably connected with a threaded rod 15, the threads on the left and right sides of the center of the threaded rod 15 are opposite, the inner sides of the two groups of adjustment grooves 14 are connected, and multiple groups of adjustment seats 4 are respectively threadedly connected to the two groups of threaded rods 15 in pairs, and motors 16 are installed at both ends of the outer side of the connecting seat 1. The driving end of the motor 16 extends to the inner side of the adjustment groove 14 and is fixedly connected to one end of the threaded rod 15. Multiple groups of threaded holes 17 are arranged on the outer side of the positioning sleeve 3. A positioning bolt 18 is threadedly connected to the inner side of the threaded hole 17, and a first rubber pad 19 is bonded to one end of the positioning bolt 18. A second rubber pad 20 is embedded and installed on one side of the arc sleeve 2. Furthermore, starting the motor 16 can drive the two groups of adjustment seats 4 on one group of threaded rods 15 to move in opposite directions, so that the arc sleeve 2 can fit tightly against the inner wall of the bearing, and then the positioning bolt 18 is screwed into the threaded hole 17. At this time, the first rubber pad 19 and the second rubber pad 20 are both in contact with the inner and outer surfaces of the bearing for positioning.
[0024] Implementation plan: align the push plate 5 on the arc sleeve 2 with the push groove and push it in. The push plate 5 is against one end of the rebound plate 7, and the two groups of slope surfaces 9 are in contact, forcing the rebound plate 7 to drive the two groups of springs 8 to retract. After the push plate 5 is fully pushed in, the rebound plate 7 is no longer blocked and will pop out by itself to resist one end of the push plate 5 to complete the positioning installation. Buckle the pull ring 12 to drive the movable rod 11 to move, so that the rebound plate 7 moves and squeezes the spring 8 again. After the rebound plate 7 fully enters the rebound groove 6, the pull ring 12 is offset and rotated to be hung on the positioning rod 13 for positioning. At this time, the arc sleeve 2 can be removed, and the starting motor 16 can drive the two groups of adjustment seats 4 on one group of threaded rods 15 to move in opposite directions, so that the arc sleeve 2 can fit the inner wall of the bearing and press it tightly. Then the positioning bolt 18 is screwed into the threaded hole 17. At this time, the first rubber pad 19 and the second rubber pad 20 are both against the inner and outer surfaces of the bearing for positioning.
