[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-6 The present invention provides an embodiment of a centering and threading ring mechanism, comprising: a displacement component 1, the displacement component 1 including a frame 101, a ball screw 102 installed inside the frame 101, a screw motor 103 installed at one end of the ball screw 102, and a screw slider 104 installed on the outer wall of the ball screw 102; the screw motor 103 and the ball screw 102 drive the screw slider 104 to perform linear displacement, and the displacement drives the limiting device 2 to adjust its position, so that it can move the workpiece to the docking guide 4 for pushing and guiding operation;

[0025] Its material pushing and guiding structure is as follows: A limiting device 2 for placing the workpiece is installed above the displacement component 1. The limiting device 2 includes an assembly seat 201 that is bolted to the lead screw slider 104. A limiting frame 202 is provided at one end of the assembly seat 201. A limiting placement opening 203 is provided inside the limiting frame 202. A driving component 3 for pushing the workpiece out from the limiting device 2 is installed on one side of the displacement component 1. A docking guide 4 for receiving the pushed-out workpiece is provided on the other side of the displacement component 1. The docking guide 4 includes a docking block 401. A displacement groove 403 is opened inside the docking block 401. The two ends of the displacement groove 403 extend to the tapered guide hole 602 and the limiting placement opening 203, respectively.

[0026] The limiting assembly 2 restricts the workpiece by limiting frame 202, so that the workpiece is placed within the limiting placement opening 203. With the drive of the displacement component 1 below, the limiting assembly 2 and the workpiece are sent into the drive component 3. The drive component 3 is a cylinder or electric cylinder, which is used to push the workpiece from the limiting placement opening 203 into the docking guide component 4 on the other side. The docking guide component 4 is provided with a displacement groove 403, which is used for the drive component 3 to push the workpiece to move. The other end of the displacement groove 403 extends to the tapered guide hole 602, so that the hole of the workpiece can be aligned with the tapered guide hole 602, which facilitates the insertion of the rod and achieves the effect of centering and passing the ring.

[0027] Furthermore, a limiting cover plate 402 is installed on the outer wall of the displacement groove 403, and a limiting block 404 is installed at one end of the displacement groove 403 near the conical guide hole 602. The limiting cover plate 402 can be used to close the side wall of the displacement groove 403, so that the internal workpiece will not fall from the side opening when it moves in the displacement groove 403, thus achieving a limiting effect. When the workpiece is pushed to the end, the limiting block 404 closes the end opening of the displacement groove 403, thereby preventing the workpiece from falling from the end opening, thus achieving a further limiting effect.

[0028] Please see Figure 4 , Figure 5The front end of the docking guide 4 is equipped with an assembly assembly 5. The outer wall of the assembly assembly 5 is equipped with a clamping member 6. The clamping member 6 includes two upper and lower jaws 603. The outer wall of the jaws 603 is equipped with a centering guide block 601. A tapered guide hole 602 is provided at the middle position of the centering guide block 601. The assembly assembly 5 includes a support arm 506. The upper end of the support arm 506 is equipped with an assembly block 501. The outer wall of the assembly block 501 is provided with a sliding groove 502. The inside of the sliding groove 502 is equipped with a limit bolt 503. A sliding block 504 is installed between the limit bolts 503. The clamping member 6 is installed on the outer wall of the sliding block 504 by bolts. One end of the assembly block 501 is provided with an insertion block 505. The outer wall of the centering guide block 601 is provided with an insertion hole 604 for the insertion block 505 to be inserted.

[0029] The clamping member 6 uses two jaws 603 to adjust the distance between the upper and lower centering guide blocks 601 respectively, so that the two centering guide blocks 601 fit together and form a tapered guide hole 602 in the middle of them, which can more effectively and accurately feed the rod through.

[0030] The clamping member 6 slides within the slide groove 502 via the sliding block 504. The position of the clamping member 6 is adjusted by sliding. After adjusting to the desired position, a limiting bolt 503 is installed within the slide groove 502 to limit the sliding block 504. The setting of the insertion hole 604 and the insertion block 505 can improve the stability and firmness of the centering guide block 601 assembly.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
