Clamping tool

Abstract

The invention relates to a clamping tool. The clamping tool comprises a pedestal, a lower pressing plate, an upper pressing plate, a first fixing piece and a second fixing piece, wherein the lower pressing plate is arranged on the pedestal; the upper pressing plate is arranged on the lower pressing plate; the first fixing piece is arranged on the upper pressing plate, and the upper pressing plateis fixed on the lower pressing plate by the first fixing piece; and the second fixing piece is arranged on the lower pressing plate, and the lower pressing plate is fixed on the pedestal by the second fixing piece. The clamping tool has the advantages of high clamping stability, capacity of adjusting the pitching position of a crystal and good heat dissipation performance.

Description

【Technical field】 [0001] The invention belongs to the field of fixtures, in particular to crystal clamping fixtures. 【Background technique】 [0002] The shape of existing crystals is basically a cuboid of several × several × several, such as: 3 × 3 × 7 crystals. [0003] In the laser debugging process, in order to ensure a satisfactory laser output index, under the condition of ensuring good heat dissipation of the laser crystal (such as LBO, etc.), it is hoped that the pitch and azimuth angle of the crystal can be adjusted. The traditional adjustment method is to fix the tooling holding the laser crystal on the two-dimensional angle adjustment frame. The characteristic of the two-dimensional angle adjustment frame is to use the expansion and contraction of the spring to realize the angle adjustment of the clamping parts on the adjustment frame. The disadvantage is that the spring is easy to fatigue, which will cause the position of the adjustment frame to change. Therefor...

Problems solved by technology

The characteristic of the two-dimensional angle adjustment frame is to use the expansion and contraction of the spring to realize the angle adjustment of the clamping parts on the adjustment frame. The disadvantage is that the spring is easy to fatigue, which will cause the position of the adjustment frame to change.

Therefore, the disadvantage of the traditional adjustment method is that it is easy to cause the crystal position to change, thereby affecting the stability of the laser index. Another disadvantage of the traditional adjustment method is that it is not conducive to the heat dissipation of the crystal.

[0004] In summary, the crystal clamping tooling in the prior art obviously has inconvenience and defects in actual use, so it is necessary to improve it
