Abstract
Description
Technical Field
[0001] This utility model relates to the field of grating installation and adjustment technology, and more specifically, to a grating installation and adjustment device. Background Technology
[0002] A grating is an optical element that uses the principle of diffraction to disperse light, and it is widely used in pulse compression, laser beam combining, spectroscopy, and other fields. In pulse compression applications, changes in the grating angle affect the time-domain waveform and compression efficiency of the output light pulse. To obtain the best pulse compression effect, it is necessary to adjust the three-dimensional angle of the grating, which requires the grating fixing device to have a high-precision and stable angle adjustment function.
[0003] Common angle adjustment frames use tension springs or disc springs to tighten the fixed plate and adjustment plate, and a screw to adjust the angle of the adjustment plate. After adjustment, the screw is locked. This method is relatively convenient. However, because it relies on spring force to maintain structural stability, the adjustment plate can still move under vibration or external force, resulting in poor structural stability and affecting the stability of the laser pulse waveform. Chinese patent CN201410633421.8 discloses a grating adjustment frame, including a base plate, adjustment plate, semi-circular plate, grating plate, and locking plate. Multiple springs are installed between the base plate and the adjustment plate. The semi-circular plate is installed in a groove, and the grating plate is vertically installed on the semi-circular plate. One side wall of the locking plate is positioned above the semi-circular plate, and the other side wall is positioned above the adjustment plate. It is secured to the semi-circular plate and the adjustment plate respectively by two studs. However, this method mainly relies on point-to-point contact, especially in pitch adjustment, where three points of contact are used. Its stability needs further improvement. Utility Model Content

Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] like Figure 1-3 As shown, this utility model provides a grating mounting and adjustment device, including an adjustment base 1 and a detachable grating clamp 15 disposed on the adjustment base 1. The grating 16 is fixed to the grating clamp 15, and the top of the grating clamp 15 is provided with a positioning hole, which can be used to fix the grating 16 by tightening screws. The adjustment base 1 can adjust the angle of the grating 16 in three-dimensional space to meet usage requirements.
[0021] The adjustment base 1 includes an adjustment plate 2, an adjustment plate 3, and a fixed base plate 4 arranged in layers from top to bottom. The grating clamp 15 is mounted on the adjustment plate 2. One side of the adjustment plate 2 is connected to the adjustment plate 3, and one side of the adjustment plate 3 is connected to the fixed base plate 4. The adjustment plate 2 can be tilted left and right with the connection point with the adjustment plate 3 as the pivot, and the adjustment plate 3 can be tilted forward and backward with the connection point with the fixed base plate 4 as the pivot.
[0022] The grating fixture 15 is mounted on the adjustment plate 2. The adjustment plate 2 has several mounting holes 17 arranged sequentially along its length. When the grating is too long, the mounting position can be changed by moving it to the left, avoiding interference with subsequent adjustments. The mounting angle of the grating 16 can be indirectly adjusted by adjusting the angles of the adjustment plates 2 and 3. The fixing plate 4 has oblong holes. The fixing plate 4 is mounted on the rotating table through these oblong holes. Before the fastening screws in the oblong holes are tightened, the horizontal rotation of the grating 16 can be adjusted by rotating the fixing plate 4. The adjustment plates 2 and 3 can be tilted in the left-right and front-back directions. This adjustment is achieved through the interaction of bolts, through holes, and screw holes, as described below.
[0023] An arc-shaped notch 5 is provided at the connection between the first adjusting plate 2 and the second adjusting plate 3, and an arc-shaped notch 6 is provided at the connection between the second adjusting plate 3 and the fixed base plate 4. The arc-shaped notches 5 and 6 reduce the strength of the connection during rotation and facilitate the rotation of the first adjusting plate 2 and the second adjusting plate 3. The first adjusting plate 2 and the second adjusting plate 3 are made of tough aluminum material, but other materials with a certain degree of deformation capability can also be used.
[0024] The adjusting plate 2 has a through hole 7 and a threaded hole 11 located away from the connection point with the adjusting plate 3. The adjusting plate 3 has a through hole 8 and a through hole 9 corresponding to the through hole 7 and the threaded hole 11. The fixed base plate 4 has a threaded hole 12 corresponding to the through hole 8. The diameters of the through holes 7 and 8 are larger than the diameter of the threaded hole 12, and the diameter of the through hole 9 is larger than the diameter of the threaded hole 11. A bolt 1 passes through the through hole 7 and the through hole 8 and extends into the threaded hole 12. A bolt 2 passes through the threaded hole 11 and the through hole 9 and abuts against the fixed base plate 4. The tilt angle of the adjusting plate 2 is adjusted by using bolts 1 and 2.
[0025] When adjusting the adjustment plate 2 downwards, the bolt is screwed into the threaded hole 12, causing the bolt to press against the adjustment plate 2 and rotate downwards around the connection point, thus moving the adjustment plate 2 downwards. When adjusting the adjustment plate 2 upwards, the bolt passes through the threaded hole 11 and the through hole 9 and abuts against the fixed base plate 4. Tightening the bolt causes the adjustment plate 2 to rotate upwards around the connection point, thus moving the adjustment plate 2 upwards. Fine-threaded bolts are used for higher adjustment precision. The vertical tilt adjustment of the adjustment plate 2 allows for the horizontal tilt adjustment of the grating 16.
[0026] The adjusting plate 2 3 is provided with a through hole 4 10 and a threaded hole 3 13, and the fixed base plate 4 is provided with a threaded hole 4 14. The diameter of the through hole 4 10 is larger than the diameter of the threaded hole 4 14. The bolt 3 passes through the through hole 4 10 and extends into the threaded hole 4 14. The bolt 4 passes through the threaded hole 3 13 and abuts against the fixed base plate 4. The tilt angle of the adjusting plate 2 3 is adjusted by the bolt 3 and the bolt 4.
[0027] When the adjustment plate 23 is tilted downwards, the bolt 3 is tightened into the threaded hole 4 14, causing the bolt 3 to press against the adjustment plate 23 and rotate downwards around the connection point, thus moving the adjustment plate 23 downwards. When the adjustment plate 23 is tilted upwards, the bolt 4 passes through the threaded hole 3 13 and abuts against the fixed base plate 4. Tightening the bolt 4 causes the adjustment plate 23 to rotate upwards around the connection point, thus moving the adjustment plate 23 upwards. The vertical tilt adjustment of the adjustment plate 23 can achieve the forward and backward tilt adjustment of the grating 16.
[0028] This design enables rotation, left-right tilt, and forward-backward tilt adjustment of the grating. These three-dimensional angle adjustments are independent and do not interfere with each other. The grating adjustment has no spring-loaded fixing structure, resulting in good stability. The overall structure is simple and easy to adjust. Furthermore, the forces exerted during adjustment by adjustment plates 2 and 3 are both applied to the fixed base plate 4, leading to higher accuracy.
[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
