[0031] The centering mechanism 3 includes a center block 31, a limiting slider 33, and a telescopic block 34 inserted into the limiting slider 33. The telescopic block 34 is used to center the bearing seat, and the limiting slider 33 is used to accommodate the telescopic block 34.

[0032] The positioning mechanism 4 includes two mutually symmetrical side positioning plates 47, which are used to quickly position the two sides of the bearing seat.

[0033] In a further embodiment, the center block 31 is slidably connected to the inside of the center groove 22, the limiting slider 33 is slidably connected to the inside of the transverse groove 23, and symmetrical limiting plates 38 are provided at the upper and lower ends of the limiting slider 33.

When the center hole of the bearing seat is smaller, it is contacted by the arc block, and when the center hole of the bearing seat is larger, it is contacted by one side of the plug-in rod.

[0039] In a further embodiment, the centering plate 21 is internally rotatably connected with a gear set 28 and a screw 29 , the drive rod 27 is meshed with the gear set 28 , the gear set 28 cooperates with the screw 29 , and the screw 29 penetrates one end of the threaded connection center block 31 .

[0040] In this embodiment, the gear set 28 is composed of two gears, one of which meshes with the gear of the drive rod 27, and the other meshes with the gear of the screw rod 29, thereby driving the screw rod 29 to rotate, thereby allowing the center block 31 to be retractable; the screw rod 29 is composed of a gear and a threaded rod.

[0041] In a further embodiment, a limiting groove 26 is opened inside the centering plate 21, and the limiting groove 26 is connected to the transverse groove 23 through the connecting groove 24. A connecting plate 48 is fixedly connected to one side of the side positioning plate 47, and the connecting plate 48 is slidably connected to the inside of the limiting groove 26.

[0042] In this embodiment, the connecting plate 48 is L-shaped, and has a dovetail block on the top, which is staggered with the dovetail block of the limiting slider 33; protective pads are installed on the opposite side of the side positioning plate 47 to protect the bearing seat when positioning to avoid damage to the bearing seat.

[0043] In a further embodiment, the internal rotation connection of the centering plate 21 is provided with a double-threaded rod 46, and the double-threaded rod 46 passes through the threaded connection connecting plate 48.

The upper base plate 42 is located above the lower base plate 44, and the upper base plate 42 and the lower base plate 44 are both fixedly connected to one side of the centering plate 21.

[0044] In this embodiment, a bearing is provided at the rotating connection of the double-threaded rod 46, and the thread passes through the thread and is connected to one end of the connecting plate 48. Therefore, when the double-threaded rod 46 rotates, the two side positioning plates 47 can move closer to or away from each other to quickly position the bearing seat.

[0046] In this embodiment, there are two positioning bolts 41 that are threaded through the lower base plate 44 and are rotatably connected to the bottom of the lower support plate 45, and there is a positioning bolt 41 above the upper base plate 42. The positioning bolt 41 is threaded through the upper base plate 42 and then rotatably connected to the top of the upper concave plate 43. The upper concave plate 43 is in a concave state to fit the curvature of the top of the bearing seat, and protective pads are provided on the upper concave plate 43 and the lower support plate 45 near the bearing seat.

[0047] The working principle of this utility model is as follows:

[0048] When the bearing seat needs to be positioned, it can be placed above the lower support plate 45, and then the drive rod 27 is rotated, and the screw 29 is rotated through the transmission of the gear set 28, so that the center block 31 is extended from the inside of the center groove 22, and in the process of extending, the limiting sliders 33 on both sides are moved away from each other through the connecting rod 32, and the telescopic block 34 will pop out immediately when the two limiting sliders 33 move away from each other, and the telescopic block 34 passes through the middle hole of the bearing seat, and as the limiting sliders 33 continue to move away from each other, the bearing seat can be found. At this time, the bearing seat will be positioned consistent with the rotation center of the lathe chuck 1 by the outward force of the telescopic block 34. At this time, By rotating the double-threaded rod 46, the two side positioning plates 47 can quickly position and clamp the two sides of the bearing seat, and then by rotating the positioning bolts 41 of the upper base plate 42 and the lower base plate 44, the upper concave plate 43 and the lower support plate 45 respectively clamp the upper and lower ends of the bearing seat, completing the clamping and positioning of the bearing seat, and finally rotating the drive rod 27 in the opposite direction to make the center block 31 shrink to the inside of the center groove 22, and let the two limiting sliders 33 move closer to each other until the center block 31 is completely retracted to the inside of the center groove 22, press the telescopic block 34 to make it shrink back to the inside of the limiting slider 33, thereby avoiding the telescopic block 34 affecting the lathe's turning of the center hole in the bearing seat.
