Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, specifically to a planar angle fine-tuning mechanism. Background Technology

[0002] Existing similar products are amplitude adjustment slides. These slides use an arc-shaped guide rail and a worm gear structure, which can make large-angle planar angle adjustments. However, this type of slide is not suitable for applications with high precision requirements. The arc-shaped guide rail and worm gear transmission used in its internal moving parts have inherent gaps between their movements. Therefore, it is only suitable for applications with low precision requirements and a wide range of adjustments.

[0003] In the existing technology, the arc adjustment slide uses an arc-shaped guide rail and a worm gear transmission to achieve the adjustment action. This mechanism is complex and costly.

[0004] In view of this, it is necessary to improve the traditional planar angle fine-tuning mechanism. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1: The specific structure of this utility model is as follows:

[0034] Please refer to the appendix. Figure 1-3 The present invention provides a planar angle fine-tuning mechanism, comprising an adjustment platform 1 and a drive mechanism.

[0035] The adjustment platform 1 has a fixed part 102 and a movable part 101, which are connected by an elastic structure 10. Both the fixed part 102 and the movable part 101 are flat plates, and one edge of each plate is connected by the elastic structure 10. The inner side of the elastic structure 10 has a rounded transition, and its outer side has a notch. Figure 1 As can be seen, the combined structure of the notch and the elastic structure 10 satisfies the requirement that the movable part 101 is elastic. The movable part 101 has an outwardly extending curved structural rod 2 connected to one end away from the elastic structure 10.

[0036] The drive mechanism is connected to the movable part, and the drive mechanism drives the movable part 101 to swing slightly through the cam structure to adjust the planar angle of the movable part 101.

[0037] The drive mechanism includes:

[0038] The motor base 8 is connected to the end of the fixing part 102 away from the elastic structure part 10;

[0039] Two bearing seats 9 are vertically fixed to the motor seat 8 and are spaced apart by a certain distance;

[0040] Two bearings 6 are provided, and the two bearings 6 are fixed to the two bearing seats 9 one to one. The extension end of the curved structure rod 2 extends to the upper region of the gap between the two bearing seats 9.

[0041] A rotating shaft 5 is inserted through the two bearings 6, and a cam is fixed on the rotating shaft 5. The rolling surface of the cam abuts against the curved structure rod 2.

[0042] Motor 3 is fixed to the motor base 8, and its drive end is connected to the rotating shaft 5 through a coupling 4.

[0043] A reset mechanism is further provided between the movable part 101 and the driving mechanism, the reset mechanism comprising:

[0044] A first screw located at the end of the curved structural rod 2;

[0045] A second screw located on the side of the motor mount 8;

[0046] The return spring 7 is held at both ends by the first screw and the second screw, respectively.

[0047] Example 2:

[0048] like Figure 1 As shown, when the movable part 101 needs to increase the angle, the motor 3 is started. The motor 3 drives the rotating shaft 5 to rotate through the coupling 4. The cam on the rotating shaft 5 rotates synchronously. Since the cam is eccentrically mounted on the rotating shaft, it will gradually lift the curved structure rod 2 during the rotation process.

[0049] The curved structure rod 2 is fixedly connected to the movable part 101, and the movable part 101 is elastically connected to the fixed part 102. The movable part 101 is raised along with the curved structure rod 2, realizing the fine adjustment of the angle of the movable part 101. At this time, the return spring 7 is in the stretched state.

[0050] When the moving part 101 needs to reduce the angle, the motor 3 reverses, and the motor 3 drives the rotating shaft 5 to reverse through the coupling 4. The cam on the rotating shaft 5 reverses synchronously, and the lower position of the cam rotates upward. At this time, the curved structure rod 2 is pulled downward by the return spring 7, and the curved structure rod 2 descends and remains in close contact with the cam.

[0051] The curved structure rod 2 descends, causing the movable part 101 to descend, thereby enabling the movable part 101 to make minor adjustments to reduce its angle.

[0052] The angle at which the moving part 101 rises and falls is determined by the rotation angle of the cam driven by the motor 3.

[0053] In summary, this utility model's planar angle fine-tuning mechanism achieves precise adjustment by using a cam to drive a movable plate to finely adjust the angle. The mechanism employs an elastic structure to allow the movable plate to finely adjust its angle. Furthermore, the cam-driven angle adjustment of the movable plate ensures flexible and reliable adjustment during the process.

[0054] The planar angle fine-tuning mechanism of this utility model is mainly designed to solve some adjustment situations with high precision requirements. The flatness after such adjustment is basically within 0.01mm and the adjustment range is not very large. Generally, the maximum adjustment stroke is within ±0.08mm. Since the flatness requirement after adjustment is high and the adjustment stroke is small, the planar angle fine-tuning mechanism of this utility model is needed to achieve this.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
