Description

Technical Field

[0001] The utility model belongs to the field of laser cutting, and in particular relates to an anti-shake structure of a high-precision laser vibrating lens. Background Art

[0002] The working principle of the laser galvanometer is to make the laser beam incident on two mirrors (scanning mirrors) and use a computer to control the reflection angle of the mirrors. The two mirrors can scan along the X and Y axes respectively, thereby achieving the deflection of the laser beam and realizing the effect of laser cutting.

[0003] The laser vibrating lens in the laser cutting machine is fixed at one end by a micro rotating motor and the other end is suspended in the air during long-term use. As a result, the motor is prone to slight vibrations after long-term use, resulting in reduced cutting accuracy. At the same time, the interior of the device is relatively closed, which can easily cause the reflective mirror to mold, resulting in poor mirror reflection efficiency, thereby reducing cutting quality.

[0004] Therefore, an anti-shake structure for a high-precision laser vibrating lens is proposed, which sets a fixed limit structure at both ends of the cutting reflective lens and a ventilation structure to alleviate the problem of slight shaking of the reflective lens driven by the motor and mildew caused by lack of ventilation affecting the reflection efficiency. Utility Model Content

[0005] In order to overcome the problem that the existing laser vibrating lens is prone to shaking and being in a closed state for a long time during use, which easily causes the reflector to mold and leads to poor laser cutting effect.

[0006] The technical solution of the utility model is: an anti-shake structure of a high-precision laser vibrating lens, comprising a shell; a second mounting groove is provided at the upper end of the shell, a third groove body is penetrated through the lower end of the inner wall of the second mounting groove, a first mounting groove is provided at the front end of the shell, a second groove body is penetrated through the rear end of the inner wall of the first mounting groove, a fourth groove body is penetrated through the rear end of the shell, a laser mounting guide tube is fixedly connected to the rear end of the shell, an anti-shake clamping assembly is provided on the fourth groove body, a second motor is fixedly connected to the lower end of the inner wall of the second mounting groove, a second reflector is fixedly connected to the lower end of the output shaft of the second motor through the third groove body, a first motor is fixedly connected to the inner wall rear end of the first mounting groove, a fixed disk is penetrated through the rear end of the output shaft of the first motor through the second groove body, and the first reflector is fixedly connected to the rear end of the fixed disk.

[0007] Preferably, by opening a fourth slot on the opposite side of the first motor, the anti-shake clamping assembly on the fourth slot clamps the other end of the first reflector while the first motor drives the first reflector to rotate, thereby improving the stability of the first reflector during use. By arranging fans on both sides of the shell, air circulation can be achieved in the shell, reducing the influence of the environment on the closed space, which can easily cause mold spots on the surfaces of the second reflector and the first reflector, and solving the problem that the vibration lens is prone to shaking and is in a closed state for a long time, which can easily cause the reflector to become moldy and lead to poor laser cutting effect.

[0008] Preferably, the anti-shake clamping assembly includes a rotating ring, a rotating column, a connecting block, a connecting rod, a sliding plate, a spring, a strip plate and a plug column; the rear end of the shell is fixedly connected to the rotating ring, and the inner wall of the rotating ring is rotatably provided with a rotating column, the rotating column passes through the fourth slot and extends to the interior of the shell, the front end of the rotating column is fixedly connected to the connecting block, the front end of the connecting block is fixedly connected to two connecting rods, a sliding plate is slidably provided on the connecting rod, the end of the connecting block and the sliding plate close to each other is fixedly connected with a spring, the front ends of the two connecting rods are jointly fixed with a strip plate, and the front end of the strip plate is fixedly connected to two plug columns. When the first motor is installed on the shell, the two plug columns on the strip plate are inserted into the limit sockets on the fixed disk, and then the rear end of the first reflector pushes the front end of the sliding plate, so that the sliding plate clamps the rear end of the first reflector through the reaction force of the spring on the connecting block.

[0009] Preferably, limiting holes are provided at both ends of the fixed disk, the inner wall of the limiting holes fits with the outer wall of the plug post, the rear end of the fixed disk fits with the front end of the strip plate, the rear end of the first reflector fits with the front end of the sliding plate, and the rear end of the connecting block fits with the rear end of the inner wall of the shell. When the first motor drives the first reflector to rotate and adjust the angle, since the plug post on the strip plate is inserted into the limiting holes, the rotating column rotates synchronously with the first reflector on the rotating ring, so that the first reflector is stably clamped by the fixed disk and the sliding plate during rotation, thereby reducing slight jitter generated during operation.

[0010] Preferably, a first slot is provided through the left and right ends of the shell, a fan is provided on the first slot, and a dustproof net is fixedly connected to the end of the two fans away from each other. During daily use, by turning on the fans on the left and right sides of the shell, the fans can exhaust and dehumidify the air in the shell. During the exhaust process, the dust can be removed through the dustproof net to prevent the dust from being dispersed to the surface of the first reflector and the second reflector.

[0011] Preferably, the lower end of the shell is fixedly connected to a base, and a lens placement groove is opened through the lower end of the base, and the lens placement groove is used to install subsequent protective lenses.

[0012] Preferably, the first reflector is located at one end of the two connecting rods close to each other, so that the two connecting rods will not block the mirror surface of the reflective end of the first reflector, causing the first reflector to be unable to reflect the laser normally.

[0013] Preferably, the axis center line of the rotating column is collinear with the axis center line of the output shaft of the first motor, so as to ensure that the clamping and anti-shake work can be carried out stably.

[0014] Beneficial effects of the utility model:

[0015] When the first motor drives the first reflector to rotate and adjust the angle, the plug post on the strip plate is inserted into the limit plug hole, so that the rotating post rotates synchronously with the first reflector on the rotating ring, so that the first reflector is stably clamped by the fixed plate and the sliding plate during the rotation process, thereby reducing the slight vibration generated during operation and solving the problem of easy vibration caused by a structure in which one end is fixed by the micro rotating motor and the other end is suspended in the air during long-term use;

[0016] By turning on the fans on the left and right sides of the housing, the fans exhaust and dehumidify the air in the housing. During the exhaust process, the dust can be removed through the dustproof net to prevent the dust from being dispersed onto the surfaces of the first reflector and the second reflector, thereby solving the problem that the cutting device is in a closed state for a long time, which easily causes the reflectors to become moldy and leads to poor laser cutting effect.

[0017] 3. When the first motor is installed on the housing, the two pins on the strip plate are inserted into the limit holes on the fixed plate, and then the rear end of the first reflector pushes the front end of the sliding plate, so that the sliding plate clamps the rear end of the first reflector through the reaction force of the spring in the connecting block.

[0027] See also Figure 4-Figure 5In this embodiment, the anti-shake clamping assembly includes a rotating ring 101, a rotating column 102, a connecting block 103, a connecting rod 104, a sliding plate 105, a spring 106, a strip plate 107 and a plug column 108; the rear end of the housing 1 is fixedly connected to the rotating ring 101, and the inner wall of the rotating ring 101 is rotatably provided with a rotating column 102, and the rotating column 102 extends into the interior of the housing 1 through the fourth slot 11, and the front end of the rotating column 102 is fixedly connected to the connecting block 103, and the front end of the connecting block 103 is fixedly connected to two connecting rods 104, and a sliding plate 105 is slidably provided on the connecting rod 104, and the end of the connecting block 103 and the sliding plate 105 close to each other A spring 106 is fixedly connected, and the front ends of the two connecting rods 104 are commonly fixed with a strip plate 107. The front end of the strip plate 107 is fixed with two plug posts 108. The front and rear ends of the fixed disk 14 are penetrated by a limiting hole 15. The inner wall of the limiting hole 15 fits with the outer wall of the plug post 108, the rear end of the fixed disk 14 fits with the front end of the strip plate 107, the rear end of the first reflector 16 fits with the front end of the sliding plate 105, and the rear end of the connecting block 103 fits with the rear end of the inner wall of the shell 1.

[0028] During operation, when the first motor 13 is mounted on the housing 1, the two pins 108 on the strip plate 107 are inserted into the limiting holes 15 on the fixed plate 14, and then the rear end of the first reflector 16 pushes the front end of the sliding plate 105, so that the sliding plate 105 clamps the rear end of the first reflector 16 through the reaction force of the spring 106 on the connecting block 103;
