[0030] like Figures 1-5 As shown, Figure 1 This is a three-dimensional structural diagram of the centering device; Figure 2 This is another three-dimensional structural diagram of the centering device; Figure 3 This is a cross-sectional schematic diagram of the centering device; Figure 4 This is a front view of the centering device; Figure 5This is a diagram illustrating the usage scenario of the centering device. The centering device includes a support assembly 1 and a positioning element 2. The positioning element 2 is rotatably mounted on the support assembly 1. In use, the support assembly 1 is connected to a vertical drilling machine, and the positioning element 2 contacts the shaft-like parts on the vertical drilling machine. The positioning element 2 determines whether the current position meets the requirements. This embodiment uses the connection between the support assembly 1 and the vertical drilling machine as an example. In other embodiments, the vertical drilling machine can be replaced with other devices.

[0031] The support assembly 1 includes a first support member 11, a second support member 12, and a third support member 13. The first support member 11 is connected to the vertical drilling machine, the second support member 12 is connected to the first support member 11, and the third support member 13 is connected to the second support member 12. The positioning member 2 is rotatably connected to the third support member 13. Specifically, along the longitudinal axis, the second support member 12 has a through hole 121. One end of the first support member 11 and one end of the third support member 13 are also located within the through hole 121. In this embodiment, both the first support member 11 and the third support member 13 are connected to the through hole 121 with a clearance fit.

[0032] Furthermore, the centering device also includes a first fixing member 3 and a second fixing member 4. The first fixing member 3 passes through the first support member 11 and the through hole 121 to prevent the first support member 11 from detaching from the through hole 121; the second fixing member 4 passes through the third support member 13 and the through hole 121 to prevent the third support member 13 from detaching from the through hole 121.

[0033] Furthermore, the outer wall of the second support member 12 has two first movable grooves 122, which are opened along the longitudinal axis and communicate with the through hole 121. The first fixing member 3 passes through the first support member 11, the through hole 121, and the two first movable grooves 122, and can also slide within the first movable grooves 122. The outer wall of the second support member 12 also has two second movable grooves 123, which are opened along the transverse axis and communicate with the through hole 121. The second fixing member 4 passes through the second support member 12, the through hole 121, and the two second movable grooves 123, and can also slide within the second movable grooves 123. Thus, the third support member 13 can rotate at a certain angle relative to the second support member 12, and the third support member 13 and the second support member 12 can move a certain distance relative to the first support member 11 along the longitudinal axis. During the position adjustment of the shaft part, it remains in contact with the positioning member 2. The change in the position of the shaft part will cause the positioning member 2 to rotate and move along the longitudinal axis within a certain range. At this time, due to the mutual cooperation between the first movable groove 122, the second movable groove 123, the first fixed member 3 and the second fixed member 4, the positioning member 2 can move along the longitudinal axis and rotate accordingly, which not only improves the smoothness of the position adjustment of the shaft part, but also protects the positioning member 2.

[0034] The centering device also includes an elastic element 5, which is located within the through hole 121. One end of the elastic element 5 is connected to the first support element 11, and the other end is connected to the third support element 13. When the positioning element 2 contacts the shaft-like part, the positioning element 2 will be subjected to the reaction force of the shaft-like part. This force will push the third support element 13 and the second support element 12 to move upward relative to the first support element 11. At this time, the elastic element 5 is compressed, and the elastic element 5 will also generate a reaction force on the third support element 13. This reaction force is transmitted to the positioning element 2, which can help alleviate the hard-contact contact between the positioning element 2 and the shaft-like part. In other words, the elastic element 5 acts as a buffer for the positioning element 2, thereby achieving a protective effect for the positioning element 2. In this embodiment, the elastic element 5 is a conventional spring structure.

[0035] The third support member 13 has a receiving groove 131. The centering device also includes a third fixing member 6. One side of the positioning member 2 is located in the receiving groove 131. The third fixing member 6 passes through the positioning member 2 and the receiving groove 131 to prevent the positioning member 2 from detaching from the receiving groove 131. The positioning member 2 is rotatably connected to the third fixing member 6, that is, the positioning member 2 can rotate relative to the third fixing member 6.

[0036] The outer surface of the positioning component 2 has a centering mark 20. The first support component 11, the second support component 12, the third support component 13, and the positioning component 2 share a common center line, and the centering mark 20 coincides with this center line. Along the center line, the end of the third support component 13 away from the second support component 12 is provided with a needle 10, which points towards the centering mark 20. In use, since the positioning component 2 can rotate relative to the third fixing component 6, that is, when the shaft part just comes into contact with the positioning component 2, if the position of the shaft part is not in accordance with the requirements, the centering mark 20 will not coincide with the center line, but will be offset, and the needle 10 and the centering mark 20 will not form an opposing distribution. Conversely, when the shaft part is adjusted to the required position, the needle 10 will be distributed in contrast to the centering mark 20 (e.g., ...). Figure 4 (The position distribution shown) Therefore, when adjusting the position of shaft parts, the needle 10 and the center mark 20 can be used as references. When the two are in opposition, it indicates that the current position of the shaft part meets the requirements.

[0037] In practical applications, the centering mark 20 can be set by a slot, such as a slot is opened on the surface of the positioning member 2 along the longitudinal axis; or it can be set by a pattern, such as a pattern is engraved or attached to the surface of the positioning member 2.

[0038] Furthermore, the side of the positioning member 2 away from the third support member 13 has a flared structure. In this embodiment, the "flared structure" refers to an opening structure on the positioning member 2 that gradually widens in the direction away from the third support member 13. To further explain, the positioning member 2 has a first inclined surface 21 and a second inclined surface 22. One end of the first inclined surface 21 is connected to one end of the second inclined surface 22, forming a flared structure. In application, the first inclined surface 21 and the second inclined surface 22 respectively contact the two sides of the shaft-like part. In this embodiment, the flared structure is V-shaped.

[0039] In summary, when the shaft part comes into contact with the flared structure of the positioning component 2, if the needle 10 on the support component 1 does not correspond to the centering mark 20, the position of the shaft part can be adjusted so that the needle 10 corresponds to the centering mark 20, and the required position can be accurately found on the shaft part. In this way, the traditional manual operation method can be changed, which not only reduces the operation requirements and simplifies the operation process, but also helps to improve accuracy, and also greatly shortens the required time, thereby improving efficiency.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
