Embodiment 1

[0017] A special fixture for optical fiber light guiding assisted laser drilling, which consists of: a bracket cover 4, the inside of the bracket cover has a ring platform, a gasket 6 is placed on the ring platform, and a gasket 6 is placed above the gasket A glass backing plate 5, a work piece 8 is placed on the glass backing plate, an optical fiber support layer 7 is placed above the work piece, a cladding 1 is provided in the middle of the optical fiber support layer, and a fiber core is housed in the cladding 2. The upper plane of the optical fiber holding layer is attached to the ring 3, and the outer diameter of the ring has threads and is connected to the bracket cover through threads.

Embodiment 2

[0019] According to the special jig for optical fiber light guiding assisted laser drilling described in Embodiment 1, the middle position of the ring is a cylindrical hole and its diameter is larger than the outer diameter of the cladding layer, and the outer diameter of the optical fiber holding layer is the same as The outer diameter of the workpiece is the same, and the inner diameter of the gasket is the same as the inner diameter of the annular platform.

Embodiment 3

[0021] According to the special fixture for optical fiber light guiding assisted laser drilling described in embodiment 1 or 2, the small hole processing method comprises the following steps:

[0022] First, clean the annular platform and threads inside the bracket cover, place the fiber core in the cladding, and then place the cladding in the inner hole of the fiber clamping layer;

[0023] Place the spacer above the ring platform, and make the inner hole of the spacer flush with the inner hole of the ring platform, then place the glass backing plate on the top of the spacer, make the glass backing plate and the inner hole of the bracket cover The threads are coaxially placed, the workpiece is placed above the glass backing plate, and then the optical fiber clamping layer with cladding and fiber core is placed above the workpiece as a whole, and the two are placed coaxially, and finally used Ring rotation clamping;

[0024] The fixation between the workpiece and the optical ...

Abstract

The invention provides an optic fiber light guide auxiliary laser punching special fixture and a method for performing small hole machining. In the prior art, punching is performed by directly illuminating the workpiece surface utilizing laser, limited by the laser and machining parameters, the hole diameter size, hole distance and hole roundness of machined holes have large deviation, and the smoothness of the machined holes also does not achieve the standard requirements. The constitution of the optic fiber light guide auxiliary laser punching special fixture comprises a support rack outer hood (4), the support rack outer hood is internally provided with an annular platform, a pad piece (6) is placed on the annular platform, a glass pad plate (5) is placed on the pad piece, a workpiece (8) is placed on the glass pad plate, an optical fiber reinforcement layer (7) is placed on the workpiece, the middle position of the inner portion of the optical fiber reinforcement layer is providedwith a wrapping layer (1), the wrapping layer is internally provided with a fiber core (2), an upper plane of the optical fiber reinforcement layer is in fit with a circular ring (3), and the externaldiameter of the circular ring is provided with screw threads and is connected with the support rack outer hood through the screw threads. The optic fiber light guide auxiliary laser punching specialfixture and the method for performing the small hole machining are used for the optic fiber light guide auxiliary laser punching special fixture.
