Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to a grating adjustment device and a laser. Background Art

[0002] In the related art, a grating is an optical element with a periodic structure, which is usually composed of a series of parallel lines or grooves of equal width and spacing engraved on a transparent material (such as glass or plastic). These lines or grooves can be transparent (transmission grating) or reflective (reflection grating) and are used to change or analyze the direction, wavelength or intensity of light. The working principle of the grating is based on the diffraction phenomenon of light. When a light wave passes through a grating, due to the periodic structure on the grating, the light wave will diffract, that is, the propagation direction of the light wave will change, and different orders of diffracted light will be generated. The direction and intensity distribution of these diffracted lights depend on the structural parameters of the grating (such as line spacing, depth, etc.) and the wavelength and angle of the incident light.

[0003] The grating is fixed by a fixing device before use. In some cases, after the grating is fixed, if the pre-installed angle of the grating deviates, the effect of the grating in changing the state of the light beam will be poor. That is, the diffracted light generated by the grating does not meet expectations. Therefore, an adjustment device is urgently needed to adjust the position of the grating. Utility Model Content

[0034] Please refer to Figures 1 to 5 In some embodiments, the grating adjustment device 10 is used to adjust the grating 20, and the grating 20 includes a first end 21 and a second end 22 opposite to each other, and the shape of the grating 20 can be a cuboid or a cube. The grating adjustment device 10 includes: a clamping member 100 and an adjustment component. The clamping member 100 is provided with a clamping groove 110, and the clamping groove 110 is used to place the grating 20. The shape of the clamping groove 110 can be adapted to the shape of the grating 20. The groove wall of the clamping groove 110 includes a first wall 120 and a second wall 150 opposite to each other. The first wall 120 is provided with a first adjustment hole 130 and a second adjustment hole 140 in a direction parallel to the height direction of the grating 20, and the number of the first adjustment hole 130 and the second adjustment hole 140 is not specifically limited. The second wall 150 is provided with a third adjustment hole 160 and a fourth adjustment hole 170 in a direction parallel to the height direction of the grating 20, and the number of the third adjustment hole 160 and the fourth adjustment hole 170 is not specifically limited.

[0035] The adjustment component includes: a first adjustment member 400, a second adjustment member 500, a third adjustment member 600 and a fourth adjustment member 700. The number of the first adjustment member 400, the second adjustment member 500, the third adjustment member 600 and the fourth adjustment member 700 is not specifically limited. The first adjustment member 400 is connected to the first adjustment hole 130 and can abut against the first end 21, the second adjustment member 500 is connected to the second adjustment hole 140 and can abut against the first end 21, the third adjustment member 600 is connected to the third adjustment hole 160 and can abut against the second end 22, and the fourth adjustment member 700 is connected to the fourth adjustment hole 170 and can abut against the second end 22. Among them, by adjusting the length of the first adjustment member 400 and the second adjustment member 500 protruding from the first wall 120 and adjusting the length of the third adjustment member 600 and the fourth adjustment member 700 protruding from the second wall 150, the angle of the grating 20 can be adjusted. Specifically, the first adjusting member 400 is disposed in the first adjusting hole 130, and the first adjusting member 400 is rotated so that the first adjusting member 400 can protrude from the first adjusting hole 130. The first adjusting member 400 can be a screw, a bolt or a rod with a thread. After the first adjusting member 400 protrudes from the first adjusting hole 130, the first adjusting member 400 can abut against the grating 20, thereby fixing the grating 20. The second adjusting member 500 is disposed in the second adjusting hole 140, and the second adjusting member 500 is rotated so that the second adjusting member 500 can protrude from the second adjusting hole 140. The second adjusting member 500 can be a screw, a bolt or a rod with a thread. After the second adjusting member 500 protrudes from the second adjusting hole 140, the second adjusting member 500 can abut against the grating 20, thereby fixing the grating 20. The third adjusting member 600 is disposed in the third adjusting hole 160, and the third adjusting member 600 is rotated so that the third adjusting member 600 can protrude from the third adjusting hole 160. The third adjusting member 600 may be a screw, a bolt or a rod with a thread. After the third adjusting member 600 protrudes from the third adjusting hole 160, the third adjusting member 600 may abut against the grating 20, thereby fixing the grating 20. The fourth adjusting member 700 is disposed in the fourth adjusting hole 170. The fourth adjusting member 700 is rotated so that the fourth adjusting member 700 can protrude from the fourth adjusting hole 170. The fourth adjusting member 700 may be a screw, a bolt or a rod with a thread. After the fourth adjusting member 700 protrudes from the fourth adjusting hole 170, the fourth adjusting member 700 may abut against the grating 20, thereby fixing the grating 20. The first adjusting hole 130, the second adjusting hole 140, the third adjusting hole 160 and the fourth adjusting hole 170 may all be threaded holes.

[0036] Among them, the first adjustment member 400 and the second adjustment member 500 are used to abut against the first end 21 together, and the third adjustment member 600 and the fourth adjustment member 700 are used to abut against the second end 22 together. In this way, in the vertical direction, the clamping member 100 and the adjustment component jointly fix the grating 20. Among them, when the grating 20 is set in the clamping groove 110, the grating 20 has a first state and a second state. Operate the adjustment component to switch the grating 20 between the first state and the second state. When the grating 20 is in the first state, the first end 21 is parallel to the first wall 120. When the grating 20 is in the second state, there is an angle between the first end 21 and the first wall 120, and the angle is an acute angle. Specifically, by operating the adjustment component, the grating 20 can be switched between the first state and the second state. Please refer to Figure 4 When the grating 20 is in the first state, the first end 21 is parallel to the first wall 120, please refer to Figure 5 When the grating 20 is in the second state, there is an angle between the first end 21 and the first wall 120, and the angle is an acute angle, that is, when the grating 20 is installed, the position of the grating 20 can be adjusted by operating the adjustment component, so that when the position of the grating 20 deviates, the position of the grating 20 can be adjusted, thereby effectively improving the measurement accuracy of the grating 20. Specifically, the grating adjustment device 10 can adjust the position of the grating 20, thereby effectively improving the measurement result of the grating 20.

[0037] The function of the adjustment component is described again below. It can be imagined that the grating adjustment device 10 can be installed on an optical platform for use. After the grating adjustment device 10 is installed, the grating 20 will usually be parallel to the horizontal direction. However, in some cases, the grating 20 may need to be offset in the horizontal direction. For example, the grating 20 is biased to the left or right. Specifically, when the grating 20 is in the first state, the first wall 120 is perpendicular to the horizontal direction, and the first end 21 is parallel to the first wall 120. At this time, the grating 20 can be placed horizontally. When it is necessary to adjust the position of the grating 20 in the horizontal direction, for example, to make an angle between the length direction of the grating 20 and the horizontal direction. At this time, rotate the adjustment component so that the distance that the second adjustment member 500 protrudes from the first wall 120 is greater than the distance that the first adjustment member 400 protrudes from the first wall 120, and the distance that the third adjustment member 600 protrudes from the second wall 150 is greater than the distance that the fourth adjustment member 700 protrudes from the second wall 150. Under the action of the adjustment component, please refer to Figure 5, the grating 20 is tilted upward along the direction from the first end 21 of the grating 20 toward the second end 22. On the contrary, if the grating 20 needs to be tilted downward along the direction from the first end 21 of the grating 20 toward the second end 22, then it is only necessary to rotate the adjustment component so that the distance that the second adjustment member 500 protrudes from the first wall 120 is less than the distance that the first adjustment member 400 protrudes from the first wall 120, and the distance that the third adjustment member 600 protrudes from the second wall 150 is less than the distance that the fourth adjustment member 700 protrudes from the second wall 150. That is, the adjustment component can deflect the grating 20 in the horizontal direction. It should be noted that when the adjustment component adjusts the position of the grating 20, it is usually a fine-tuning method, and the actual angle adjustment is very small, and only a slight rotation of the adjustment component is required.

[0038] For further information, please refer to Figure 1 to Figure 2 In some embodiments, the grating adjustment device 10 further includes a base 200 and an adapter 300. The clamping member 100 and the adapter 300 are both mounted on the base 200. The clamping member 100 has a first plane 180 on the side away from the clamping groove 110, and the adapter 300 has a second plane 340, and the first plane 180 abuts against the second plane 340. Among them, the first plane 180 can be perpendicular to the horizontal direction, and the second plane 340 can also be perpendicular to the horizontal direction. When the first plane 180 abuts against the second plane 340, the clamping member 100 can be perpendicular to the horizontal plane, thereby effectively ensuring that the grating 20 is perpendicular to the horizontal plane. In other words, after the first plane 180 and the second plane 340 are abutted, the verticality of the grating 20 can be better.

[0039] For further information, please refer to Figure 1 to Figure 2 In some embodiments, the grating adjustment device 10 further includes a first operating member, a second operating member and a fastener. The adapter 300 is provided with a fifth adjustment hole 310, and the number of the fifth adjustment holes 310 is not specifically limited. The clamp 100 is provided with a sixth adjustment hole, and the fastener is threadedly connected to the hole wall of the fifth adjustment hole 310 and the hole wall of the sixth adjustment hole. The orthographic projections of the fifth adjustment hole 310 and the sixth adjustment hole on the grating 20 are both located in the middle of the grating 20. Among them, the fastener can be a screw, a bolt or a rod with a thread, and the fastener can connect the adapter 300 and the clamp 100, so as to realize the installation and fixing of the clamp 100 on the adapter 300. The adapter 300 is further provided with a seventh adjustment hole 320 and an eighth adjustment hole 330, and the orthographic projections of the seventh adjustment hole 320 and the eighth adjustment hole 330 on the grating 20 are respectively located on both sides of the horizontal central axis of the grating 20, or, the orthographic projections of the seventh adjustment hole 320 and the eighth adjustment hole 330 on the grating 20 are respectively located on both sides of the vertical central axis of the grating 20. Figure 2For example, the seventh adjustment hole 320 and the eighth adjustment hole 330 can be located on the left and right sides of the fifth adjustment hole 310, respectively, or the seventh adjustment hole 320 and the eighth adjustment hole 330 can be located on the upper side and the lower side of the fifth adjustment hole 310, respectively. The first operating member is arranged in the seventh adjustment hole 320, and the first operating member can protrude from the seventh adjustment hole 320 and abut against the clamping member 100, and the second operating member is arranged in the eighth adjustment hole 330, and the second operating member can protrude from the eighth adjustment hole 330 and abut against the clamping member 100. By adjusting the length of the first operating member protruding from the adapter 300, or adjusting the length of the second operating member protruding from the adapter 300, the angle of the grating 20 can be adjusted. The fifth adjustment hole 310, the sixth adjustment hole, the seventh adjustment hole 320 and the eighth adjustment hole 330 can all be threaded holes. Specifically, the first operating member, the second operating member and the fastener cooperate to rotate the grating 20 relative to the adapter 300, so as to adjust the pitch angle or left-right angle of the grating 20. Taking the pitch angle adjustment of the grating 20 as an example, the seventh adjustment hole 320 and the eighth adjustment hole 330 can be located on the upper side and the lower side of the fifth adjustment hole 310, respectively. After loosening the fastener, there is a gap between the clamping member 100 and the adapter 300, and then by tightening the first operating member and loosening the second operating member, one end of the first operating member abuts the clamping member 100, which can realize the grating 20 from vertical to elevation. On the contrary, after tightening the second operating member and loosening the first operating member, one end of the second operating member abuts the clamping member 100, which can realize the grating 20 from vertical to depression. It should be noted that when the pitch angle of the grating 20 needs to be adjusted, the fastener needs to be loosened, and when it is not necessary to adjust, the fastener needs to be tightened to ensure that the grating 20 is vertical. The cooperation among the first operating member, the second operating member and the fastener not only has a small number of parts and a simple structure, but also has a low cost.

[0040] For further information, please refer to Figure 1 to Figure 2 In some embodiments, the base 200 includes a first body 210 and a second body 250, the clamping member 100 and the adapter 300 are both mounted on the first body 210, and the first body 210 is rotatably connected to the second body 250. Specifically, after the first body 210 rotates relative to the second body 250, the grating 20 can be rotated. That is, after the base 200 is fixed on the optical platform, the grating 20 can also be rotated, so that the grating 20 is suitable for different scenes, thereby improving the applicability of the grating 20.

[0041] Further, the following describes how the first body 210 rotates relative to the second body 250. Figures 2 to 3In some embodiments, the first body 210 includes a first body portion 220 and a first protruding portion 230. The first protruding portion 230 is connected to the first body portion 220, and the first protruding portion 230 protrudes relative to the first body portion 220. The first body 210 may be in a "convex" shape. The second body 250 includes a second body portion 260 and a second protruding portion 270, the second protruding portion 270 is connected to the second body portion 260, and the second protruding portion 270 protrudes relative to the second body portion 260, and the second body portion 260 and the second protruding portion 270 jointly define a rotation groove 290. The first protruding portion 230 is disposed in the rotation groove 290, and the first body portion 220 abuts against the second protruding portion 270. Specifically, the shape of the first protruding portion 230 may be cylindrical, the shape of the rotation groove 290 is cylindrical, and the first protruding portion 230 may rotate in the rotation groove 290.

[0042] Furthermore, after the first body 210 rotates relative to the second body 250, the first body 210 and the second body 250 can be restricted from rotating by a locking member, which can keep the position of the grating 20 fixed. Therefore, in some embodiments, the grating adjustment device 10 further includes a locking member, which is used to restrict the first body 210 from rotating relative to the second body 250.

[0043] Further, the following describes how the locking member restricts the first body 210 from rotating relative to the second body 250. Figure 2 In some embodiments, the first body 210 is provided with a waist-shaped hole 240, the second body 250 is provided with a through hole 280, and the locking member is passed through the waist-shaped hole 240 and the through hole 280. Specifically, the locking member can be a bolt and a nut. After the bolt passes through the waist-shaped hole 240 and the through hole 280, the nut and the bolt are tightened to constrain the first body 210 to rotate relative to the second body 250. Among them, in addition to bolts and nuts, the locking member can also be a pin or a rivet. Among them, after the first body 210 is provided with the waist-shaped hole 240, when the grating 20 needs to be rotated, the nut can be loosened, and then the first body 210 is rotated, and then the nut can be tightened. This method does not require the removal of nuts and bolts, which can improve work efficiency.

[0044] For further information, please refer to Figure 2In some embodiments, a plurality of waist-shaped holes 240 are provided, and the plurality of waist-shaped holes 240 are arranged along the central circumference of the first body 210. When the angle at which the grating 20 needs to rotate is relatively large, a plurality of waist-shaped holes 240 are provided, for example, three waist-shaped holes 240 are provided, and the three waist-shaped holes 240 may be respectively the first waist-shaped hole 240, the second waist-shaped hole 240 and the third waist-shaped hole 240. The bolt is initially provided in the first waist-shaped hole 240. After the first body 210 is rotated, the bolt abuts against the end of the first waist-shaped hole 240, preventing the first body 210 from continuing to rotate. At this time, the rotation angle of the first body 210 has not reached the required angle. Therefore, the bolt can be taken out and placed in the second waist-shaped hole 240, so as to continue to rotate the first body 210, so that the rotation angle of the grating 20 meets the requirement. Afterwards, by tightening the nut and the bolt, the rotation of the first body 210 and the second body 250 can be limited. Specifically, the plurality of waist-shaped holes 240 can facilitate the first body 210 to rotate at a larger angle, and after the rotation, it is convenient to use a locking piece to fix it.

[0045] For further information, please refer to Figure 2 In some embodiments, a plurality of through holes 280 are provided, and the plurality of through holes 280 are provided along the central circumference of the second body 250. The plurality of through holes 280 can improve the locking effect between the first body 210 and the second body 250. When adjusting the rotation angle between the first body 210 and the second body 250, the first body 210 can be rotated, and then the locking piece is penetrated through the waist-shaped hole 240 and the through hole 280 to lock, so as to prevent the first body 210 and the second body 250 from rotating relative to each other. Alternatively, the first body 210 remains stationary, and then the second body 250 is rotated, which can facilitate the adjustment of the rotation angle of the second body 250 relative to the optical platform. After the second body 250 is rotated, the first body 210 and the second body 250 can be locked by penetrating the waist-shaped hole 240 and the through hole 280 through the locking piece, so as to prevent the two from rotating relative to each other. In addition, when there are multiple through holes 280 and waist-shaped holes 240, multiple locking members can also be set, and each locking member is inserted into a group of waist-shaped holes 240 and through holes 280, which can improve the effect of the locking member in limiting the rotation between the first body 210 and the second body 250.
