Embodiment 1

[0035]In this embodiment, an integrated clamping and clamping mechanism for an optical lens, the main structure includes: a clamping arm, a disc mechanism, a frame mechanism 16, a base, and a knob unit; the clamping arm and The disc mechanism is movably connected, and the disc mechanism rests on the card frame mechanism 16, which is fixedly connected with the base, and the knob unit is installed in the base; the operator operates the rear end of the clamp arm with three fingers to open the front end of the clamp arm. Open, put the optical lens under test, release your finger and the perspective mirror is clamped, then place the disc mechanism of the clamping arm on the clamp mechanism, rotate the magnet knob to magnetically lock the disc mechanism. Such as Image 6 shown.

[0036] In this embodiment, the clamping arm and the knob unit are used for clamping and constraining, without artificially clamping the test piece, avoiding the risk that the surface of the test piece is e...

Embodiment 2

[0038] This embodiment is basically the same as Embodiment 1, especially in that:

[0039] Among them, through figure 1 It can be seen that the clamping arm comprises two upper clamping arms and a lower clamping arm and a sleeve 8, and the upper clamping arm comprises: a clamping head 1, an upper clamping arm front part 2, threaded holes 3. The groove 4, the rear part of the upper clamping arm 5, the connection unit 6; the lower clamping arm includes: a clamping head 1, and the lower clamping arm 7. The connection method is as follows: a clamping head 1 is installed at one end of the front part 2 of the upper clamping arm, and the clamping head 1 is shaped as a rectangular parallelepiped with one side of the arc, and the edge of the tested part is realized through the recess part on it. For clamping, the other end is welded on the front part 2 of the upper clamping arm; a groove 4 and a threaded hole 3 are opened in the middle of the other side of the front part 2 of the uppe...

Abstract

The invention discloses an integrated clamping and fastening mechanism for an optical lens, and the principle is that the clamping and fastening mechanism is designed, so that the clamping mechanism can be manually controlled, a tested piece is clamped, and the tested piece is placed on a main frame body of a clamp mechanism to be clamped and fixed. Therefore, manual taking of the tested piece is avoided, and the possibility of measurement errors and contamination of the tested piece is reduced. The integrated clamping and fastening mechanism for the optical lens mainly structurally comprises a clamping arm, a disc mechanism, a clamping frame mechanism, a base and a knob unit.

Description

technical field [0001] The invention relates to an integrated clamping and clamping mechanism for optical lenses, in particular, the non-contact clamping and clamping of the measured piece can be realized through the provided clamping device and accessory mechanism, which is suitable for the optical lens Pick up and clamp. Background technique [0002] Optical lenses play an important role in the construction and design of optical and laser systems because of their high-quality surface topography distribution. Accurate measurement of its surface using laser interferometer is an important means to quantify and evaluate its surface quality. When using interferometry for surface measurement, the optical lens as the object under test needs to be picked up from the storage box, the object under test is clamped manually or mechanically, and then the lens is clamped with a fixture. [0003] Due to the existence of high-quality topography distribution on the surface of the optical...
