Description

Technical Field

[0001] This utility model relates to the field of laser height adjustment technology, specifically to a device for adjusting the height of a laser. Background Technology

[0002] A laser is a device that emits laser light. Based on its characteristics, lasers are currently used in laser processing technology. This technology couples the laser beam into a water jet, using the laser energy to remove material. The advantage of this technology is that the water jet not only guides the laser beam to the processing surface but also provides cooling, reducing the heat-affected zone and thus improving processing accuracy and quality, while also reducing processing time and waste.

[0003] To further investigate the applicability of lasers used in water-guided lasers, it is often necessary to conduct comparative tests using lasers of various specifications. Before the comparative experiment, the laser needs to be fixed on an optical experimental platform, and the laser outlet needs to be at the same horizontal height as the experimental optical lens. However, since laser housings from different manufacturers have various sizes and laser outlet heights, it is necessary to place shims under the laser for normal experimentation. Therefore, it has become common practice to provide a set of shims for each specification of laser. Currently, a simple fastening method uses multiple layers of shims to elevate the laser and uses pressure blocks to press the corners for fixation. This method has disadvantages such as high fixing difficulty, cumbersome fixing process, difficult adjustment, and the need for multiple people to assist. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a device for adjusting the height of a laser, making it easier to adjust the height of the laser.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a device for adjusting the height of a laser, comprising an optical experimental platform and a laser, wherein the optical experimental platform and the laser are connected by four pads, each pad comprising an internally threaded sleeve and a support rod, wherein a screw is fixedly connected to the top of the internally threaded sleeve, the screw passes through the base of the laser and is connected to a fastening nut, the support rod comprising an adjustment part and a mounting part from top to bottom, wherein the adjustment part is provided with an external thread, one end of the adjustment part is disposed in the internally threaded sleeve, an adjustment seat is provided above the mounting part, and a support seat is connected below the mounting part, the support seat being mounted on the optical experimental platform.

[0006] Furthermore, the two adjacent support seats are mounted on the optical experimental platform using U-shaped pressure plates.

[0007] Furthermore, the support base is provided with a mounting groove, and a bearing is provided in the mounting groove. The lower end of the mounting part is installed on the inner ring of the bearing.

[0008] Furthermore, the threaded end of the support rod is provided with scale values, and the values ​​of the scale values ​​decrease sequentially from top to bottom.

[0009] Furthermore, the bottom of the support base is provided with a groove, and an anti-slip pad is provided in the groove.

[0010] Furthermore, the side wall of the adjustment seat is provided with adjustment holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives the support rod to rotate through the adjusting seat, and the rotation of the support rod causes the internal threaded sleeve to move up and down, thereby driving the laser to rise or fall; since the support rod and the support seat rotate relative to each other, the height of the laser can be precisely adjusted after installation without lifting the support seat, reducing the difficulty of adjustment. At the same time, when the support rod rotates, the support seat does not rotate, reducing the friction between the support seat and the optical experimental platform, making the adjustment process more convenient.

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] This utility model provides a device for adjustable laser height, including an optical experimental platform 1 and a laser 2. The optical experimental platform 1 and the laser are connected by four blocks. Each block includes an internally threaded sleeve 3 and a support rod 4. A screw 5 is fixed to the top of the internally threaded sleeve 3. The screw 5 passes through the base of the laser 2 and is connected to a fastening nut 6. The support rod 4 includes an adjustment part 41 and a mounting part 42 from top to bottom. The adjustment part 41 has an external thread, and one end of the adjustment part 41 is located inside the internally threaded sleeve 3. An adjustment seat 7 is provided above the mounting part 42, and a support seat 8 is connected below the mounting part 42. The support seat 8 is mounted on the optical experimental platform 1 and has a mounting groove. A bearing 10 is installed in the mounting groove, and the lower end of the mounting part 42 is installed on the inner ring of the bearing 10.

[0019] like Figure 1 As shown, the support base 8 is placed on the optical experimental platform 1 and fixed by the Y-shaped pressure plate 9. Then, the screw 5 is inserted into the mounting hole of the laser 2 base and fixed by the fastening nut 6, thus mounting the laser 2 on the optical experimental platform. According to the required height, the adjusting seat 7 is rotated. The rotation of the adjusting seat 7 drives the support rod 4 to rotate. The rotation of the support rod 4 will cause the internal threaded sleeve 3 to move up and down. Since the support base 8 and the mounting part 42 are rotatably connected by the bearing 10, the support rod 4 and the support base 8 can rotate relative to each other. Therefore, the support base 8 does not rotate during the rotation of the support rod 4. Therefore, it is not necessary to lift the support base 8 during the adjustment process, and the bottom of the support base 8 will not be affected by friction. At the same time, the height of the laser can be adjusted in time according to the horizontal height of the experimental optical lens, which is convenient and quick.

[0020] The two adjacent support seats 8 are mounted on the optical experimental platform 1 by U-shaped pressure plates 9.

[0021] like Figure 1 As shown, the U-shaped pressure plate 9 has multiple sets of elongated holes. The bottom of both sides of the elongated connecting hole of the U-shaped pressure plate 9 is stepped. The support base 8 is located on the steps. The optical experimental platform 1 has multiple sets of connecting holes. The U-shaped pressure plate 9 is fixed to the optical experimental platform 1 by bolts. The U-shaped pressure plate 9 can be used to quickly install multiple lasers 2 of different sizes.

[0022] The threaded end of the support rod 4 has a scale value 43, and the values ​​of the scale value 43 decrease sequentially from top to bottom.

[0023] like Figure 1 As shown, the scale value 43 pointed to by the bottom of the internal thread sleeve 3 is the height to which the laser 2 is raised. By observing the size of the scale value 43, it is easy to adjust and keep the height of the four pads at the bottom of the laser 2 consistent, so that the laser 2 is kept balanced.

[0024] The bottom of the support base 8 is provided with a groove 11, and an anti-slip pad 12 is provided in the groove 11.

[0025] like Figure 1 As shown, when the anti-slip pad 12 is placed in the groove 11, a portion of the anti-slip pad 12 protrudes from the groove 11 and contacts the optical experimental platform 1, thereby increasing the friction between the base 8 and the optical experimental platform 1 and improving the stability of the laser 2 installation.

[0026] An adjustment hole 13 is provided on the side wall of the adjustment seat 7.

[0027] like Figure 1 As shown, the adjustment hole 13 is an internal hexagonal structure. In use, by inserting an internal hexagonal wrench into the adjustment hole 13 and then controlling the rotation of the internal hexagonal wrench, the adjustment seat 7 is rotated, which provides a point of force for rotating the adjustment seat 7 and facilitates rotation.

[0028] Operating principle: First, adjust the approximate height of the four pads according to the horizontal height of the experimental optical lens. Then, install the four pads at the four corners of the bottom of the laser 2. During installation, insert the screw 5 into the mounting hole at the bottom of the laser 2 and fix it with the fastening bolt 6. Then, use adhesive to stick the anti-slip pad 12 into the groove 11 at the bottom of the support base 8. Place it on the optical experimental platform 1 and fix it with the Y-shaped pressure plate 9. After installation, compare the height of the laser 2 with the horizontal height of the experimental optical lens. If the height of the laser 2 is higher or lower than the horizontal height of the experimental optical lens, the laser will be installed accordingly. The height of the laser 2 can be adjusted by inserting an Allen wrench into the adjustment hole 13. Rotating the Allen wrench rotates the adjustment seat 7, which in turn rotates the support rod 4. Since the support rod 4 and the support seat 8 rotate relative to each other, the support seat 8 does not rotate. The rotation of the support rod 4 causes the internal threaded sleeve 3 to move up and down, thus changing the height of the laser 2. This allows for online adjustment of the laser 2's height. Compared with existing technologies, adjusting the height of the laser 2 is more convenient and faster, saving installation time. Furthermore, installation can be done by one person, thus saving manpower.
