Laser drilling jig

Abstract

The invention discloses a laser drilling fixture, comprising: a mounting seat, the mounting seat includes a first mounting platform and a second mounting platform arranged up and down in sequence, the first mounting platform is provided with a first supporting plate, and the second mounting platform There is a second support plate on the top, the first support plate is surrounded by a plurality of first support blocks formed by seamlessly cutting the annular placenta in the radial direction, and the second support plate is formed by a plurality of fan-shaped second support blocks Surrounded by formation. It also includes a force-applying strut assembly passing through the central holes of the first support plate and the second support plate. The force-applying support column assembly is set in cooperation with the central hole of the first support plate to simultaneously squeeze the multiple first support blocks so that the multiple first support blocks can slide outwards in the radial direction synchronously, and then the thin-walled tapered The big end of the ring is stretched radially outward; the force-applying strut assembly is arranged in cooperation with the center hole of the second support plate to simultaneously squeeze multiple second support blocks so that the multiple second support blocks are synchronously moved along the Sliding radially outward thereby braces the small end of the thin-walled tapered ring radially outward.

Description

technical field [0001] The invention relates to the field of laser drilling jigs, in particular to a laser drilling jig. Background technique [0002] As attached figure 1 As shown, it is required to perform laser drilling on the surface of an annular thin-walled part with a thickness of 0.8mm, and the small holes to be processed are densely distributed. [0003] Since the wall thickness of the annular thin-walled part is only 0.8mm, the deformation of the thin-walled part is relatively large after processing. There will be a "stacking" phenomenon in which the air film holes are superimposed on each other. [0004] Since the inclination angle of the air film hole to be processed has exceeded the swing range of the laser head of the laser drilling equipment, the thin-walled parts need to be clamped and fixed with the small end facing down and the big end facing up. The existing double support tooling adopts two The support blocks respectively tighten the small end and the ...

Problems solved by technology

[0005] The invention provides a laser drilling jig to solve the problem that the existing double-support tooling is prone to stacking of gas film holes during processing, inconvenient clamping and dismounting of thin-walled parts, and easy to cause thin-walled parts.
