Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser processing equipment technology, specifically to a laser light guide arm adjustment seat. Background Technology
[0002] In the field of laser processing, CO2 lasers are widely used in processes such as cutting and welding due to their high power and stability. However, the wavelength of CO2 lasers is 10.6 micrometers, which cannot be transmitted through optical fibers. Therefore, a rigid optical path system (i.e., a light guide arm composed of reflecting mirrors) is required for laser transmission. The light guide arm typically consists of multiple reflecting mirrors, which reflect the laser light from the laser to the processing head.
[0003] In practical applications, when laser light is output from the laser, its optical path may not perfectly coincide with the axis of the light guide arm, leading to deviations during transmission. Furthermore, factors such as mechanical assembly errors, vibration, or temperature changes can also cause optical path offsets, affecting the precise transmission of the laser. Therefore, the reflecting mirror needs to have angle adjustment capabilities to ensure the collimation of the laser beam and processing accuracy.
[0004] Currently, traditional light guide arm reflector mounts are mostly fixed designs with limited adjustment capabilities. They typically rely on mechanical adjustment of the overall structure or lens replacement, which is cumbersome and makes fine adjustments difficult. Although some adjustable mounts use screw adjustments, they lack a stable multi-point support structure, making them prone to lens shift due to loosening or uneven force, thus affecting the stability of the optical path. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a laser light guide arm adjustment seat.
[0006] The technical solution of this utility model is:
[0007] Laser guide arm adjustment base, including: The mounting base includes a mounting base body, which has an inlet and an outlet. A mirror mounting surface is provided at the intersection of the axes of the inlet and the outlet, and the mirror mounting surface is perpendicular to the angle bisector of the axes of the inlet and the outlet. A mirror mount assembly includes a mirror mount, which is fixedly mounted on a mirror mount mounting surface. The mirror mount has a mirror groove on the side facing the mirror mount mounting surface. A reflective mirror is mounted in the mirror groove by an elastic element. The reflective mirror is used to reflect laser light. The adjustment structure has three contact points with the top edge of the reflective lens, and the adjustment structure is used to adjust the angle of the reflective lens.
[0008] Preferably, the inlet and outlet are provided with threads for connection with other equipment of the light guide arm.
[0009] Preferably, the mounting surface of the mirror base has a positioning groove on one side and threaded holes symmetrically provided on the other side. The threaded holes extend into the side of the mounting base body and penetrate the mounting base body, and the axes of the threaded holes intersect.
[0010] Preferably, the mirror groove is offset from the center of the mirror base, and a limiting groove is provided on the side of the mirror groove away from the center of the mirror base, and the limiting groove corresponds to the positioning groove.
[0011] Preferably, the elastic element includes a first elastic element located at the center of the bottom surface of the reflective lens for supporting the center of the reflective lens, and a second elastic element is provided on the outside of the first elastic element.
[0012] Preferably, the reflective lens has a pressure ring at its edge, and the second elastic element is located below the pressure ring to support it. The pressure ring is in contact with the adjustment structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a mirror mount assembly on the mounting surface of the mirror mount to reflect laser light and change the direction of the laser. A first and second elastic element support the reflecting mirror, and a multi-point support structure is used to achieve fixation. By rotating the adjusting screw, the reflecting mirror can rotate around the support ball, thus adjusting the optical path. Simultaneously, the elastic force of the elastic element applies pressure to the adjusting screw, preventing it from loosening. The overall structure is simple and easy to install and adjust.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments: Laser guide arm adjustment base, including: Mounting base 1 includes mounting base body 11, which has an inlet 12 and an outlet 13. A mirror mounting surface 14 is provided at the intersection of the axes of the inlet 12 and the outlet 13. The mirror mounting surface 14 is perpendicular to the angle bisector of the axes of the inlet 12 and the outlet 13.
[0019] The mounting base body 11 is made of metal casting and then machined. The laser enters from the inlet 12 and exits from the outlet 13. In this embodiment, the axes of the inlet 12 and the outlet 13 are perpendicular, and the angle between the mounting surface 14 of the mirror base and the axes of the inlet 12 and the outlet 13 is 45°.
[0020] The inlet 12 and outlet 13 are threaded.
[0021] Used for connecting with other devices in the light guide arm.
[0022] The mounting surface 14 of the mirror base has a positioning groove 15 on one side and threaded holes 16 symmetrically provided on the other side. The threaded holes 16 extend to the side of the mounting body 11 and penetrate the mounting body 11, and the axes of the threaded holes 16 intersect.
[0023] There are two threaded holes 16. The two threaded holes 16 are close to one end of the mirror mount surface 14, inclined towards the center and far apart from each other.
[0024] The mirror mount assembly 2 includes a mirror mount 21, which is fixedly installed on the mirror mount mounting surface 14. The mirror mount 21 has a mirror groove 23 on the side facing the mirror mount mounting surface 14, and a reflective mirror 27 is installed in the mirror groove 23 by means of an elastic element.
[0025] The mirror mount 21 is made of metal material by turning. The mirror mount 21 is fixedly installed on the mirror mount mounting surface 14 by fixing bolts 22.
[0026] Reflecting lens 27 is used to reflect laser light.
[0027] The shape of the reflecting mirror 27 is adapted to the mirror groove 23. The outer diameter of the reflecting mirror 27 is slightly smaller than the inner diameter of the mirror groove 23. The reflecting mirror 27 can slide along the axis of the mirror groove 23 and can tilt at a small angle. The mirror groove 23 is offset from the center of the mirror base 21. A limiting groove 24 is provided on the side of the mirror groove 23 away from the center of the mirror base 21. The limiting groove 24 corresponds to the position of the positioning groove 15.
[0028] The eccentric setting of the mirror groove 23 is to ensure that part of the reflecting mirror 27 is located at the threaded hole 16.
[0029] The elastic element includes a first elastic element 25, which is located in the middle of the bottom surface of the reflective lens 27 and is used to support the center of the reflective lens 27. A second elastic element 26 is provided on the outside of the first elastic element 25.
[0030] The first elastic element 25 can be made of foam cotton. The first elastic element 25 is attached to the bottom surface of the reflective lens 27 by adhesive to support the reflective lens 27.
[0031] The reflective lens 27 has a pressure ring 28 at its edge, and the second elastic element 26 is located below the pressure ring 28 to support the pressure ring 28.
[0032] The pressure ring 28 can be made of metal and is snapped around the edge of the reflective lens 27. The second elastic element 26 can be a wave-shaped elastic washer.
[0033] Adjustment structure 3 has three contact points with the top edge of the reflective lens 27. Adjustment structure 3 is used to adjust the angle of the reflective lens 27.
[0034] The pressure ring 28 contacts the adjustment structure 3. This prevents the adjustment structure 3 from directly contacting the reflecting mirror 27, which could lead to uneven stress on the reflecting mirror 27 and subsequent breakage.
[0035] The adjustment structure 3 includes a support ball 31 and two adjustment screws. The support ball 31 is located in the positioning groove 15, and the adjustment screws are threadedly installed in the threaded hole 16. The bottom end of the adjustment screw is a ball head.
[0036] After the mirror mount 21 is fixedly installed on the mirror mount mounting surface 14, the adjusting screw and the support ball 31 will squeeze the reflective mirror 27 and the pressure ring 28, thereby squeezing the first elastic element 25 and the second elastic element 26. At the same time, the support ball 31 will be inserted into the limiting groove 24. The elastic force of the first elastic element 25 and the second elastic element 26 can drive the pressure ring 28 to fit tightly against the adjusting structure 3, ensuring the stability of the reflective mirror 27.
[0037] The adjusting screws are divided into a first adjusting screw 32 and a second adjusting screw 33. The first adjusting screw 32 is located near the outlet 13, and the second adjusting screw 33 is located near the inlet 12.
[0038] When the first adjusting screw 32 is turned clockwise, the first adjusting screw 32 moves toward the bearing ring 28, causing the reflecting mirror 27 to rotate toward the outlet 13, and at the same time rotate toward the mirror groove 23.
[0039] When the first adjusting screw 32 is turned counterclockwise, the first adjusting screw 32 moves away from the pressure ring 28, causing the reflecting mirror 27 to rotate toward the entrance port 12 and at the same time rotate toward the mirror mount surface 14.
[0040] When the second adjusting screw 33 is turned clockwise, the second adjusting screw 33 moves toward the bearing ring 28, causing the reflecting mirror 27 to rotate toward the entrance port 12, and at the same time rotate toward the mirror groove 23.
[0041] When the second adjusting screw 33 is turned counterclockwise, the second adjusting screw 33 moves away from the pressure ring 28, causing the reflecting mirror 27 to rotate toward the outlet 13 and at the same time rotate toward the mirror mount surface 14.
[0042] The first adjusting screw 32 and the second adjusting screw 33 work together to change the path of the laser emission, so that the laser coincides with the axis of the emission port 13.
[0043] Working principle: The laser is injected into the inlet 12, shines on the reflecting mirror 27, is reflected, and then exits from the outlet 13.
[0044] When the first adjusting screw 32 is turned clockwise, the first adjusting screw 32 moves toward the bearing ring 28, causing the reflecting mirror 27 to rotate toward the outlet 13, and at the same time rotate toward the mirror groove 23.
[0045] When the first adjusting screw 32 is turned counterclockwise, the first adjusting screw 32 moves away from the pressure ring 28, causing the reflecting mirror 27 to rotate toward the entrance port 12 and at the same time rotate toward the mirror mount surface 14.
[0046] When the second adjusting screw 33 is turned clockwise, the second adjusting screw 33 moves toward the bearing ring 28, causing the reflecting mirror 27 to rotate toward the entrance port 12, and at the same time rotate toward the mirror groove 23.
[0047] When the second adjusting screw 33 is turned counterclockwise, the second adjusting screw 33 moves away from the pressure ring 28, causing the reflecting mirror 27 to rotate toward the outlet 13 and at the same time rotate toward the mirror mount surface 14.
[0048] By adjusting the rotation direction and number of rotations of the first adjusting screw 32 and the second adjusting screw 33, the reflection angle of the reflecting lens 27 can be finely adjusted, thereby adjusting the path of the laser emission so that the laser coincides with the axis of the emission port 13.
