一种固定机构及激光加工设备

Abstract

本申请公开了一种固定机构及激光加工设备。固定机构用于固定镜片，固定机构包括基座与压紧件，基座上设有支撑部与容置空间，容置空间中设有限位部，压紧件安装于限位部，限位部能够限制压紧件沿第一方向的位移；镜片沿第一方向限位于支撑部与压紧件之间。本申请的固定机构无需繁琐的螺丝拧紧等操作，也不需要等待胶水变干，只需将镜片放置到位，安装压紧件即可完成固定，大大简化了装配流程，提高了装配效率，节省了装配时间，能够快速地将镜片安装到激光加工设备中，减少了设备停机等待的时间，进而提高了整个生产过程的效率。

Claims

1. A securing mechanism for securing a lens, the securing mechanism comprising: The device includes a base and a clamping member. The base has a support portion and a receiving space. The receiving space has a limiting portion. The clamping member is installed on the limiting portion. The limiting portion can restrict the displacement of the clamping member along a first direction. The lens is limited to be positioned between the support portion and the clamping member along the first direction.

2. The securing mechanism of claim 1, wherein, The limiting part is a limiting groove provided at the edge of the accommodating space. The limiting groove includes a first bottom surface and is used to restrict the pressing member from moving toward the support part.

3. The securing mechanism of claim 2, wherein, The limiting groove includes a first side surface, and the projection of the first side surface along the first direction is inside the first bottom surface.

4. The securing mechanism of claim 3, wherein, The clamping element is a pressure ring, which includes an outer edge and an inner edge; The first side is an annular surface, the outer edge abuts against the annular surface, and the inner edge of the pressure ring abuts against the lens.

5. The securing mechanism of claim 4, wherein, A notch is formed between the first and last ends of the pressure ring, and both the first and last ends of the pressure ring are provided with operating parts; Under the action of external force, the operating part can drive the first end and the last end of the pressure ring to move closer to each other, causing the pressure ring to contract; after the external force is removed, the first end and the last end of the pressure ring can move away from each other, allowing the pressure ring to elastically recover.

6. The securing mechanism of claim 5, wherein, The operating part is an operating hole or a protrusion.

7. The securing mechanism of claim 1, wherein, The clamping member includes a clamping member body and at least two pressure plates. The clamping member body is installed on the limiting part, and the pressure plates are disposed on the clamping member body and can abut against the lens to limit the lens along the first direction between the support part and the pressure plates.

8. The securing mechanism of claim 7, wherein, The clamping member includes three clamping plates, which are spaced apart from each other on the main body of the clamping member.

9. The securing mechanism of claim 7, wherein, The outer edge of the clamping component body is mounted on the limiting part, and the inner edge of the clamping component body is provided with an opening groove, and the pressure plate is located in the opening groove.

10. The securing mechanism of claim 9, wherein, The opening groove is adapted on one side along the first direction for the lens to extend into, so that the lens can be pressed against by the pressure plate.

11. The securing mechanism of claim 7, wherein, One end of the pressure plate is connected to the main body of the clamping member, and the other end of the pressure plate is a free end. The free end of the pressure plate is provided with a protrusion, which is used to press against the lens.

12. The securing mechanism of claim 1, wherein, Along the first direction, the accommodating space penetrates the base, and the accommodating space includes a first accommodating space and a second accommodating space that are interconnected. The depth of the first accommodating space along the first direction is less than or equal to the thickness of the lens along the first direction. The limiting part is disposed in the second accommodating space; The support portion is located on the side of the first accommodating space away from the second accommodating space; or, the support portion is located outside the accommodating space, and the first accommodating space is located between the second accommodating space and the support portion.

13. A laser processing apparatus characterized by comprising: It includes a lens and a fixing mechanism as described in any one of claims 1 to 12, wherein the lens is disposed in the receiving space.
