Problems solved by technology

However, the existing lens fixing methods usually include threaded connections, rotating structures, etc. During the disassembly process of the lens, these structures often cause dust pollution due to friction, which in turn affects the energy distribution of the beam, and eventually causes the optical equipment to fail. use
In addition, the existing lens fixing method is also difficult to ensure the coaxiality of the lens and the beam, which will directly cause the actual beam center to deviate from the theoretical beam center, seriously affect the processing accuracy of the equipment, and even cause safety hazards, resulting in major economic losses

Embodiment 1

[0042] Such as Figure 1-Figure 6As shown, the embodiment of the present invention provides a lens fixing device, which includes a base 1 , a plurality of adjusting balls 2 and an elastic member 3 . The base 1 is circular and includes a first installation step 11 and a first fixing groove 13 ; the first installation step 11 is connected to the first inner wall 12 of the base 1 , and the first installation step 11 is used to support the lens 100 . The first fixing groove 13 is arranged on the first outer wall 16 of the base 1, and extends along the circumferential direction of the first outer wall 16. The first fixing groove 13 is provided with a plurality of ball holes 14, and the plurality of ball holes 14 extend along the first outer wall 16. The fixing grooves 13 are evenly spaced in the circumferential direction, and the ball holes 14 run through the first inner wall 12 . A plurality of adjusting balls 2 are clamped in the ball hole 14 , and the adjusting balls 2 can cont...

Embodiment 2

[0049] Such as Figure 7 As shown, in the embodiment of the present invention, the lens fixing device has the same adjustment ball 2, elastic member 3 and substantially the same base 1 as the first embodiment, the lens 100 used for fixing is a convex lens, and the upper bottom surface 101 of the lens 100 and the lower bottom surface 102 are arc surfaces. The difference between the embodiment of the present invention and the first embodiment is that the fixing surface 111 of the first installation step 11 is an arc-shaped surface, and the arc-shaped fixing surface 111 abuts against the lower bottom surface 102 of the convex lens, so that the fixing of the lens 100 is more reliable .

Embodiment 3

[0051] Such as Figure 8 As shown, in the embodiment of the present invention, the lens fixing device has the same adjustment ball 2, elastic member 3 and substantially the same base 1 as the first embodiment, and the lens 100 used for fixing is a wedge-shaped lens, and the top of the wedge-shaped lens 100 The bottom surface 101 is a slope, and the lower bottom surface 102 is a plane. The difference between the embodiment of the present invention and the first embodiment is that the first fixing groove 13 is provided with two ball holes 14, and the two ball holes 14 are evenly spaced along the circumference of the first fixing groove 13, that is, the two ball holes 14 It is arranged symmetrically with respect to the center of the first fixing groove 13; correspondingly, two adjustment balls 2 are provided, and each adjustment ball 2 is snapped into a ball hole 14 respectively, and the lower spherical surface of the adjustment ball 2 abuts against the upper surface of the lens ...

Abstract

The invention belongs to the technical field of optical lens installation, and particularly relates to a lens fixing device which comprises a base, multiple adjusting balls and an elastic piece. The base is annular and comprises a first mounting step and a plurality of ball holes, and the first mounting step is arranged on the first inner wall of the base and used for supporting the lens; the multiple ball holes are evenly formed in the base in the circumferential direction of the base at intervals and penetrate through the first inner wall. The adjusting balls are clamped in the ball holes and can be propped against the edge of the upper bottom surface of the lens; the elastic piece is clamped on the base, abuts against the adjusting balls and is configured to apply pressure to the adjusting balls. According to the lens fixing device, the elastic piece applies the same acting force to the lens through the adjusting balls evenly arranged in the circumferential direction to achieve self-centering adjustment and fixation of the lens, the coaxiality of the lens and a light beam is effectively guaranteed, friction dust cannot be generated in the lens dismounting and mounting process, and the lens fixing device is simple in structure, clean and firm in installation.

Description

technical field [0001] The invention relates to the technical field of optical lens installation, in particular to a lens fixing device. Background technique [0002] With the gradual deepening of people's exploration of the optical field, more and more optical equipment is used in industrial production, such as laser cutting machines, photolithography machines, etc. In optical production equipment, according to the physical characteristics of light, it is often necessary to change the beam propagation path by adding various lenses to meet various needs, and further use the beam energy to achieve the purpose of industrial production. However, the existing lens fixing methods usually include threaded connections, rotating structures, etc. During the disassembly process of the lens, these structures often cause dust pollution due to friction, which in turn affects the energy distribution of the beam, and eventually causes the optical equipment to fail. use. In addition, the ...
