[0002] A knurled micro shaft alignment fixture is a specialized tool or device used to ensure precise alignment of a knurled micro shaft during machining, assembly, or testing. This fixture is crucial for ensuring the knurled portion of the micro shaft fits accurately with other components.

[0003] When the current knurled micro-shaft alignment tool is in use, due to the special shape of the outer surface of the knurled micro-shaft shell, it may shake when placed inside the tool. During alignment, its movement or tilting inside the tool can easily affect the alignment effect. In addition, due to the tight fit between the tool and the shaft body, the friction of the silicone strip, the limitations of the tool structure, and the lack of special tools or operating space, it is not convenient to remove the knurled micro-shaft after alignment.

[0029] The present invention is described in further detail below with reference to the accompanying drawings.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0033] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a knurled micro shaft alignment tool comprises:

[0034] A base 1 is provided with a circular hole 3 on one side of the base 1, a positioning groove 4 is provided on one side of the inner wall of the circular hole 3, and a driving member 6 is installed on the other side of the base 1;

[0035] A fixing assembly 2 is provided inside the base 1 for fixing the knurled micro-shaft housing. The fixing assembly 2 includes a plurality of silicone strips 24. An alignment assembly 7 is provided on one side of the fixing assembly 2 for assembling the knurled micro-shaft workpiece.

[0036] The extrusion component 5 is arranged outside the fixing component 2 to extrude the assembled knurled micro shaft.

[0037] Preferably, the fixing assembly 2 also includes a fixing seat 21, a fixing ring 22 is installed inside the fixing seat 21, one end of the fixing ring 22 is connected to a circular ring 23, and multiple silicone strips 24 are evenly distributed on the inner wall of the circular ring 23. One end of the fixing seat 21 is fixedly connected to the inner wall of the base 1. The alignment assembly 7 includes a fixing part 71, and an annular groove 72 is provided on both sides of the inner wall of the fixing part 71. A silicone kit 73 is embedded in the annular groove 72, and an anti-collision pad 74 is fixedly connected to the front of the fixing part 71, so that the shaft housing is smoothly pushed into the interior of the circular ring 23 until one end of the shaft housing is tightly embedded in the inner wall of the fixing ring 22, ensuring that the outer wall of the shaft housing and the inner wall of the fixing ring 22 fit perfectly without any room for shaking. Subsequently, using the structure of multiple silicone strips 24, they can fit tightly to the uneven shape of the outer surface of the shaft housing, providing the shaft housing with all-round support that conforms to its shape, thereby significantly reducing the possibility of the shaft housing shaking and ensuring that the shaft housing is fixed more firmly and reliably. After securing the shaft housing, the workpiece is precisely inserted into the interior of the mounting bracket 71. Once inserted, the workpiece's inner and outer walls are precisely squeezed by the silicone sleeve 73, ensuring stable fixation and precise alignment with the shaft housing. This setup not only facilitates subsequent tooling operations but also effectively ensures smooth and accurate installation of the knurled micro-shaft.

[0038] Specifically, the driving member 6 is an air pump, and the output end of the driving member 6 is connected to one side of the fixing member 71 .

[0039] Preferably, the extrusion assembly 5 includes a threaded ring 51, a threaded rod 52 is provided on one side of the threaded ring 51, one end of the threaded rod 52 is connected to an extrusion rod 54, one side of the extrusion rod 54 is fixedly connected to a positioning rod 55, the other side of the threaded ring 51 is fixedly connected to the outer wall of the base 1, the outer wall of the threaded rod 52 is threadedly connected to the inner wall of the threaded ring 51, the other end of the threaded rod 52 is connected to a turntable 53, the extrusion rod 54 is slidably connected to the inner wall of the circular hole 3, the outer wall of the positioning rod 55 is slidably connected to the inner wall of the positioning groove 4, the specifications of the extrusion rod 54 are slightly smaller than the fixed ring 22, and rotating the turntable 53 counterclockwise can restore it to its original position and move it to the inside of the circular hole 3.

[0040] As can be seen from the above, after the knurled micro-shaft is aligned and assembled, the operator rotates the turntable 53 clockwise, and this action will drive the threaded rod 52 to rotate inside the threaded ring 51. Since the threaded rod 52 and the extrusion rod 54 are rotationally connected, the rotation of the threaded rod 52 will cause it to move toward the inside of the base 1 inside the threaded ring 51, and then push the extrusion rod 54 to be inserted into the interior of the fixed seat 21. It is worth noting that the extrusion rod 54 and the positioning rod 55 can be combined to smoothly pass through the interior of the fixed seat 21 as a whole. During the insertion process, the extrusion rod 54 is restricted by the positioning rod 55 to ensure that it is inserted horizontally and stably into the interior of the fixed seat 21. This action will push the knurled micro-shaft outward, making it easier for the staff to remove it. The entire operation process is smooth and efficient, which significantly improves work efficiency.

[0041] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
