[0002] Ultra-precision laser is a device that uses laser technology to achieve high-precision processing. It has the advantages of high stability, high precision, and high speed. The research and application of ultra-precision lasers provide important support for the development of high-end manufacturing. The working principle is to use the high energy density of lasers to process materials, and to achieve micron-level or even nano-level processing of materials by precisely controlling parameters such as laser power, pulse width, and frequency. The laser adjustment bracket is a device specially used to adjust the laser lens.

[0043] In one embodiment, the water cooling mechanism 2 further includes a water outlet 205 and a water inlet 206;

[0044] Among them, the water inlet 206 is opened on one side of the fixing seat 101, the end of the first water channel 201 away from the second water channel 202 is connected to the water inlet 206, the drain port 205 is opened on one side of the lens bracket 102, one end of the third water channel 204 is connected to the drain port 205, the inner side walls of the drain port 205 and the water inlet 206 are both slidably connected with a sealing plug 41, and the inner side walls of the second water channel 202, the first water channel 201 and the third water channel 204 are threadedly connected with a plurality of sealing screws 42.

[0045] The sealing plug 41 is used to seal the drain port 205 and the water inlet 206 , and the water inlet 206 is used to connect the external cooling medium supply pipeline with the first water channel 201 ; the drain port 205 is used to connect the medium circuit with the third water channel 204 .

[0046] In one embodiment, three adjusting knobs 43 are threadedly connected to one side of the fixing seat 101 , and one end of the three adjusting knobs 43 passes through the inner wall of the fixing seat 101 and is rotatably connected to the inner wall of the lens holder 102 .

[0047] The distance between the lens support 102 and the fixing seat 101 is adjusted by rotating the adjusting knob 43 and cooperating with the fixing seat 101 to drive the lens support 102 to move by using the thread.

[0048] In one embodiment, the connection mechanism 3 is a connection pipe 301 ; one end of the connection pipe 301 is connected to one end of the second water channel 202 , and the other end of the connection pipe 301 is connected to one end of the third water channel 204 .

[0049] The cooling medium flowing out of the second water channel 202 is introduced into the third water channel 204 through the connecting pipe 301 , so that the cooling medium can continue to flow inside the lens holder 102 to absorb the heat of the lens holder 102 .

[0052] When the utility model is in operation: first, the laser adjustment bracket is installed to the specified position, and the sealing plug 41 is moved out from the drain port 205 and the water inlet 206, so that the external cooling medium supply pipeline is connected to the first water channel 201 through the water inlet 206, and the medium circuit is connected to the third water channel 204 through the drain port 205.

[0053] When the laser adjustment bracket is installed, the adjustment knob 43 is rotated to cooperate with the fixing base 101 to use the thread to drive the lens bracket 102 to move, and the distance between the lens bracket 102 and the fixing base 101 is adjusted.

[0056] Embodiment 2

[0057] like Figure 1-Figure 10 As shown, the embodiment of the utility model also provides an ultra-precision laser adjustment bracket with a water cooling device, including a frame assembly 1 and a water cooling mechanism 2, the frame assembly 1 includes a fixing seat 101, a lens bracket 102 and four limit seats 103;

[0058] The lens support 102 is arranged on one side of the fixing seat 101, the four limit seats 103 are respectively arranged on the side adjacent to the fixing seat 101 and the lens support 102, the water cooling mechanism 2 is arranged inside the fixing seat 101 and the lens support 102, and a connecting mechanism 3 is arranged between the fixing seat 101 and the lens support 102;

[0059] The water cooling mechanism 2 is used to introduce the cooling medium into the interior of the fixing seat 101, and cooperates with the connecting mechanism 3 to make the cooling medium in the fixing seat 101 flow into the interior of the lens bracket 102, so as to utilize the flowing cooling medium to absorb the heat of the laser adjustment bracket; the water cooling mechanism 2 includes a first water channel 201, a second water channel 202 and a third water channel 204;

[0060] The first water channel 201 is opened on one side of the inner wall of the fixing seat 101, the second water channel 202 is opened on the other side of the inner wall of the fixing seat 101, the second water channel 202 is connected with the first water channel 201, and the limiting seat 103 is opened inside the lens bracket 102;

[0061] The connecting mechanism 3 is used to connect the fixing seat 101 and the lens bracket 102 .

[0062] The difference from the first embodiment is that the connecting mechanism 3 is composed of a bellows 311, an outer sleeve 312, an inner sleeve 313 and a telescopic spring 314;

[0063] One end of the bellows 311 is connected to an end of the second water channel 202 away from the first water channel 201 , and the other end of the bellows 311 is connected to an end of the third water channel 204 away from the drain port 205 .

[0064] The inner wall of the four limit seats 103 is provided with eight limit slots 44 , the outer wall of the four limit seats 103 is threadedly connected with six limit screws 46 , three hook springs 45 are arranged between the four limit seats 103 , and the two ends of the three hook springs 45 are respectively hung on the outer walls of the six limit screws 46 .

[0065] One end of the outer sleeve 312 is fixedly connected to the inner wall of a limiting groove 44, one end of the inner sleeve 313 is fixedly connected to the inner wall of another limiting groove 44, the outer wall of the inner sleeve 313 is slidably connected to the inner wall of the telescopic spring 314, the bellows 311 is located inside the outer sleeve 312 and the inner sleeve 313, and the telescopic spring 314 is fixedly connected between the outer walls of the outer sleeve 312 and the inner sleeve 313.

[0066] The rest of the structure is the same as that of the first embodiment.

[0067] When the laser adjustment bracket is installed, the lens bracket 102 is driven to move by the screw thread by rotating the adjustment knob 43 in cooperation with the fixing seat 101, and the distance between the lens bracket 102 and the fixing seat 101 is adjusted. At the same time, the moving lens bracket 102 drives the outer sleeve 312 and the bellows 311 to move. The moving outer sleeve 312 slides on the outer wall of the inner sleeve 313 and drives the telescopic spring 314 to stretch or contract. The moving bellows 311 follows the lens bracket 102 to expand and contract. The inner sleeve 313 is set to limit the expanded and contracted bellows 311 to prevent it from being unable to be effectively reset after expansion. Then, the fixing seat 101 and the lens bracket 102 where the connecting mechanism 3 is set can be connected to ensure that the overall volume of the laser adjustment bracket remains unchanged. When the laser is working, the cooling medium flowing out of the second water channel 202 is introduced into the interior of the third water channel 204 through the bellows 311, so that the cooling medium can smoothly flow from the fixing seat 101 into the lens bracket 102. However, the production and processing cost and processing difficulty are relatively higher than those of the first embodiment.

[0068] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
