Description

Technical Field

[0001] This utility model belongs to the field of laser lens installation, specifically a fiber laser lens assembly installation structure. Background Technology

[0002] Currently, both the emitting and reflecting lenses of a laser are fixed by a lens mounting base, which typically has a mounting slot for fixing the lens.

[0003] A search revealed a Chinese patent (authorization announcement number CN218102019U) disclosing a lens mounting and sealing device for a laser cavity. This patent includes a first fixture and a second fixture that can be interconnected. The first fixture has a first groove on its front surface for placing a lens, and the second fixture has a second groove on its front surface for placing a lens. The bottom surface of the first groove has a first through hole penetrating the first fixture, and the bottom surface of the second groove has a second through hole penetrating the second fixture. The first fixture also has a connecting plate for fixing it to the laser cavity. This application provides a lens mounting and sealing device for a laser cavity. By using multiple rubber rings, it achieves good airtightness between the lens and the laser cavity, improving the sealing effect. Simultaneously, fixing the lens with the fixtures facilitates lens assembly and disassembly without affecting or contaminating other optical components within the cavity.

[0004] In existing technologies, lens mounts are generally fixed to the back seat with several screws. However, this method is cumbersome to install, inconvenient to disassemble and maintain, and the lens mount is prone to falling off freely after the limiting position is released. If it is not caught in time, the lens mount is prone to falling. Therefore, this utility model provides a fiber laser lens assembly mounting structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, which typically involve fixing lens mounts to the back seat with several screws, this method is cumbersome to install, inconvenient to disassemble and maintain, and prone to falling off freely after the limiting mechanism is released. If not caught in time, the lens mount is at risk of falling. This utility model proposes a fiber laser lens assembly mounting structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fiber laser lens assembly mounting structure of this utility model includes a housing, a baffle fixedly connected to the inner wall of the housing, a through groove opened inside the baffle, a plurality of clamping blocks slidably connected at equal intervals to the inner wall of the housing, a clamping plate fixedly connected to one side of each clamping block, a lens body arranged between the plurality of clamping plates, an installation groove opened at the bottom of the housing, a threaded ring threadedly connected to the inner wall of the installation groove, a top ring fixedly connected to the top of the threaded ring, an inclined groove opened at the bottom of each clamping block, the inclined groove cooperating with the top ring, and a reset assembly arranged inside the housing.

[0007] Preferably, the reset assembly includes a plurality of first sliding shafts, which are equidistantly fixedly installed inside the housing. Each of the first sliding shafts has a first slider slidably connected to its outer wall. Each of the first sliders is fixedly connected to a plurality of clamping blocks. Each of the first sliding shafts has a first spring sleeved on its outer wall. One end of the first spring is fixedly connected to the first slider, and the other end of the first spring is fixedly connected to the housing.

[0008] Preferably, a rubber pad is fixedly connected to the outer wall of the clamp.

[0009] Preferably, a toothed ring is fixedly connected to the outer wall of the threaded ring.

[0010] Preferably, a plurality of second sliding shafts are fixedly connected at equal intervals to the inner wall of the baffle, and a second slider is slidably connected to the outer wall of each of the plurality of second sliding shafts. A second spring is sleeved on the outer wall of each of the plurality of second sliding shafts. One end of the second spring is fixedly connected to the second slider, and the other end of the second spring is fixedly connected to the baffle. A side plate is fixedly connected to the bottom of each of the plurality of second sliders. The bottom of the side plate is arc-shaped, and a slot for use with a clamping plate is opened inside the side plate.

[0011] Preferably, the inner wall of the side plate is fixedly connected with a plurality of rotating shafts at equal intervals, and the outer wall of each of the plurality of rotating shafts is rotatably connected with a pulley.

[0012] Preferably, a rubber ring is fixedly connected to the outer wall of the pulley.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The fiber laser lens assembly mounting structure of this utility model, by rotating the threaded ring, causes the threaded ring to move upward, which in turn drives the top ring to move upward. After the top ring moves upward, it simultaneously presses against the inclined grooves at the bottom of several clamping blocks. Under the pressure of the top ring, the four clamping plates move closer to each other, clamping and fixing the lens body in the middle. When it is necessary to replace the lens body, it is only necessary to rotate the threaded ring in the opposite direction to move the threaded ring downward. Under the action of the first spring, the clamping blocks can be reset, making it easier to clamp and fix the next lens body. This simplifies the steps of lens body installation and disassembly, making it more efficient.

[0015] 2. The fiber laser lens assembly mounting structure of this utility model, when the lens body is inserted into the housing, the lens body abuts against the arc surface of the bottom of several side plates. Under the pressure of the lens body, the several side plates open simultaneously. Under the action of several second springs, the several side plates clamp the lens body, helping to limit the lens body and eliminating the need for manual support of the lens body. After the contact clamps are used to install the lens body, the lens body is prevented from falling directly by the auxiliary limiting effect of the several side plates. The pulleys can reduce the friction between the side plates and the lens body, making it easier to move the lens body downwards or upwards. Attached Figure Description

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a fiber laser lens assembly mounting structure, including a housing 1. A baffle 11 is fixedly connected to the inner wall of the housing 1. A through groove 12 is opened inside the baffle 11. A plurality of clamping blocks 13 are equidistantly slidably connected to the inner wall of the housing 1. A clamping plate 14 is fixedly connected to one side of the clamping block 13. A lens body 19 is arranged between the plurality of clamping plates 14. A mounting groove 16 is opened at the bottom of the housing 1. A threaded ring 17 is threadedly connected to the inner wall of the mounting groove 16. A top ring 21 is fixedly connected to the top of the threaded ring 17. The bottom of the clamping block 13... An inclined groove 2 is provided, which is used in conjunction with the top ring 21. A reset assembly is provided inside the housing 1. The reset assembly includes several first sliding shafts 22, which are equidistantly fixed inside the housing 1. The outer walls of the several first sliding shafts 22 are slidably connected to first sliders 23. The several first sliders 23 are respectively fixedly connected to several clamping blocks 13. The outer walls of the several first sliding shafts 22 are fitted with first springs 24. One end of the first spring 24 is fixedly connected to the first slider 23, and the other end of the first spring 24 is fixedly connected to the housing 1.

[0034] Through the above technical solution, the lens body 19 is inserted into the housing 1 and pressed against the bottom of the baffle 11. The threaded ring 17 is rotated to move the threaded ring 17 upward, which drives the top ring 21 to move upward. After the top ring 21 moves upward, it simultaneously presses against the inclined grooves 2 at the bottom of several clamping blocks 13. Under the pressure of the top ring 21, the inclined grooves 2 move closer to each other, which drives the clamping blocks 13 to move closer to each other, and the four clamping plates 14 move closer to each other, clamping and fixing the lens body 19 in the middle. While the clamping blocks 13 move, they drive the first slider 23 to move, pressing the first spring 24. When the lens body 19 needs to be replaced, the threaded ring 17 only needs to be rotated in the opposite direction to move the threaded ring 17 downward, which drives the top ring 21 to move downward. After the top ring 21 moves downward, it separates from the inclined grooves 2. Without the pressure of the top ring 21, the clamping blocks 13 can be reset under the action of the first spring 24, which facilitates the clamping and fixing of the next lens body 19. This simplifies the steps of installing and disassembling the lens body 19 and makes it more efficient.

[0035] Specifically, such as Figure 5 As shown, a rubber pad 15 is fixedly connected to the outer wall of the clamp 14.

[0036] Through the above technical solution, the rubber pad 15 can increase the friction between the clamping plate 14 and the lens body 19, thereby improving the clamping firmness.

[0037] Specifically, such as Figures 1-2 As shown, a toothed ring 18 is fixedly connected to the outer wall of the threaded ring 17.

[0038] Through the above technical solution, the toothed ring 18 can increase the friction of the outer wall of the threaded ring 17, making it easier to rotate and adjust the threaded ring 17.

[0039] Specifically, such as Figures 1-5 As shown, a number of second sliding shafts 3 are fixedly connected at equal intervals on the inner wall of the baffle 11. A second slider 31 is slidably connected to the outer wall of each of the second sliding shafts 3. A second spring 32 is sleeved on the outer wall of each of the second sliding shafts 3. One end of the second spring 32 is fixedly connected to the second slider 31, and the other end of the second spring 32 is fixedly connected to the baffle 11. A side plate 33 is fixedly connected to the bottom of each of the second sliders 31. The bottom of the side plate 33 is arc-shaped, and a slot 37 for use with the clamping plate 14 is opened inside the side plate 33.

[0040] With the above technical solution, when the lens body 19 is inserted into the housing 1, the lens body 19 presses against the arc surface at the bottom of several side plates 33. Under the pressure of the lens body 19, several side plates 33 open simultaneously. As the several side plates 33 move, they drive several second sliders 31 to move, pressing several second springs 32. After the lens body 19 presses against the baffle 11, under the action of several second springs 32, several side plates 33 clamp the lens body 19, helping to limit the lens body 19 and eliminating the need for manual support of the lens body 19. After the contact clamp 14 is used to install the lens body 19, the lens body 19 is prevented from falling directly by the auxiliary limiting effect of several side plates 33.

[0041] Specifically, the inner wall of the side plate 33 is fixedly connected with several rotating shafts 34 at equal intervals, and the outer walls of the rotating shafts 34 are rotatably connected with pulleys 35; the outer walls of the pulleys 35 are fixedly connected with rubber rings 36.

[0042] Through the above technical solution, the pulley 35 can reduce the friction between the side plate 33 and the lens body 19, making it easier to move the lens body 19 downward or upward. The rubber ring 36 can protect the surface of the lens body 19 and prevent scratches from appearing on the outer wall of the lens body 19.

[0043] like Figures 1 to 5 As shown, the working principle is as follows:

[0044] In use, the lens body 19 is inserted into the housing 1 and pressed against the bottom of the baffle 11. When the lens body 19 is inserted into the housing 1, it presses against the arc surfaces at the bottom of several side plates 33. Under the pressure of the lens body 19, the side plates 33 open simultaneously. As the side plates 33 move, they drive several second sliders 31 to move, pressing several second springs 32. After the lens body 19 presses against the baffle 11, the side plates 33 clamp the lens body 19 under the action of the second springs 32, helping to... The auxiliary limiting mechanism for the lens body 19 eliminates the need for manual support. After the lens body 19 is installed on the contact clamp 14, the auxiliary limiting mechanism of several side plates 33 prevents the lens body 19 from falling directly. The pulleys 35 reduce the friction between the side plates 33 and the lens body 19, facilitating downward or upward movement of the lens body 19. The rubber rings 36 protect the surface of the lens body 19, preventing scratches on its outer wall. Rotating the threaded ring 17 causes it to move upward. The movement of the top ring 21 causes it to move upwards. Simultaneously, the top ring 21 presses against the inclined grooves 2 at the bottom of several clamping blocks 13. Under the pressure of the top ring 21, the inclined grooves 2 move closer together, causing the clamping blocks 13 to move closer together, and the four clamping plates 14 to move closer together, clamping and fixing the lens body 19 in the middle. The rubber pads 15 increase the friction between the clamping plates 14 and the lens body 19, improving the clamping firmness. As the clamping blocks 13 move, they also move the first slider 23, compressing the first spring 24. When it is necessary to adjust the lens body... When replacing the lens body 19, simply rotate the threaded ring 17 in the reverse direction to move it downwards. The toothed ring 18 increases the friction on the outer wall of the threaded ring 17, making it easier to rotate and adjust the threaded ring 17. The downward movement of the threaded ring 17 drives the top ring 21 to move downwards. After the top ring 21 moves downwards, it separates from the inclined groove 2. Without the compression of the top ring 21, the clamping block 13 can be reset under the action of the first spring 24, making it easier to clamp and fix the next lens body 19. This simplifies the steps of installing and removing the lens body 19, making it more efficient.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0046] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
