Description

Technical Field

[0001] This utility model relates to the field of grating blade technology, specifically to an adjustable grating blade clamping device. Background Technology

[0002] Grating blades are an important component of gratings. A grating is an optical element composed of a large number of parallel slits or reflective surfaces of equal width and spacing. These key slits or reflective surfaces are like "blades", hence the name grating blades.

[0003] In the use of spectrometers, bolts and nuts are usually used to clamp the grating blades onto the base, and then the position of the base and the grating blades on the base is adjusted by an adjustment device to meet different optical performance requirements.

[0004] The grating blades are then clamped with bolts and nuts. It is difficult to control the clamping force on the grating blades. If the clamping force is too large, the grating blades will easily deform. If the clamping force is too small, the grating blades will be unstable when installed on the base, which will affect the optical performance of the grating blades.

[0005] Based on this, the present invention designs an adjustable grating blade clamping device to solve the above problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4An adjustable grating blade clamping device includes a base 1, a base 3 slidably connected to the inner wall of the base 1, an adjustment mechanism 2 on the surface of the base 1, and a constant pressure mechanism 4. The constant pressure mechanism 4 includes two electric push rods 44 fixedly connected to one side of the base 3. A liquid storage cylinder 41 is fixedly connected to the telescopic end of the electric push rod 44. The liquid storage cylinder 41 is filled with hydraulic oil. A sealing frame 42 is slidably connected to the inner wall of the liquid storage cylinder 41. An anti-slip pad 43 is slidably connected to the inner wall of the sealing frame 42. A control component 45 is provided on the surface of the liquid storage cylinder 41. The control component 45 is used to control the anti-slip pad 43 to maintain constant pressure on the end of the grating blade. A first spring 46 is fixedly connected to the opposite end of the liquid storage cylinder 41 and the sealing frame 42.

[0031] A spectrometer is an instrument that uses optical principles to analyze the spectrum of a substance. The grating blade, as the core optical element in a spectrometer, mainly uses its diffraction and dispersion characteristics to separate light of different wavelengths.

[0032] In this embodiment of the invention, during use, a suitable grating blade is selected and inserted into the base 3. The electric push rod 44 is manually activated, and the telescopic end of the electric push rod 44 moves, causing the liquid storage cylinder 41 to move. The movement of the liquid storage cylinder 41 causes the sealing frame 42 and the anti-slip pad 43 to move, so that the anti-slip pad 43 abuts against the surface of the grating blade. At this time, the liquid storage cylinder 41 and the sealing frame 42 continue to move towards the anti-slip pad 43, so that the sealing frame 42 abuts against the top of the anti-slip pad 43. At this time, the liquid storage cylinder 41 moves on the surface of the sealing frame 42, so that the hydraulic oil inside the liquid storage cylinder 41 is pushed to the control component 45. When the liquid storage cylinder 41 moves to a suitable position, the control component 45 automatically closes the electric push rod 44, so that the anti-slip pad 43 abuts against the end of the grating blade at constant pressure, thereby clamping the grating blade in the base 3. When it is necessary to adjust the position of the grating blade on the base 1, the corresponding positions of the grating blade and the base 3 on the base 1 are adjusted by the adjustment mechanism 2. The grating blade is used to separate light of different wavelengths to form a spectrum. The adjustment mechanism 2 and the constant pressure mechanism 4 can precisely adjust the position and angle of the grating blades, thereby improving the resolution and measurement accuracy of the spectrometer.

[0033] In this embodiment of the invention, the liquid storage cylinder 41, the electric push rod 44, the anti-slip pad 43, and the sealing frame 42 are used to achieve flexible clamping of the grating blades. The control component 45 is used to achieve constant pressure clamping of the grating blades, which ensures the stability of the clamping of the grating blades. Compared with the existing method of clamping the grating blades with excessive force, which can easily cause deformation of the grating blades, this method avoids damage to the grating blades caused by clamping, thereby ensuring the optical performance of the grating blades.

[0034] In some embodiments, such as Figure 3-4As shown, in a preferred embodiment of this utility model, the control component 45 includes a control cylinder 452 fixedly connected to one side of the base 3. The control cylinder 452 is filled with hydraulic oil. A moving rod 453 is slidably connected to the inner wall of the control cylinder 452. A spring switch button 454 is provided at one end of the control cylinder 452. A hose 451 is connected to the top of the reservoir 41. The other end of the hose 451 is connected to the inner wall of the control cylinder 452. A second spring 47 is fixedly connected to the opposite end of the sealing frame 42 and the anti-slip pad 43. Two abutment pads 48 are slidably connected to the inner wall of the base 3. A spring 49 is fixedly connected to the surface of the base 3, and the other end of the spring 49 is fixedly connected to the inner wall of the base 3. A third spring 410 is fixedly connected to one end of the inner wall of the control cylinder 452, and the other end of the third spring 410 is fixedly connected to one end of the moving rod 453. A limit rod 411 is fixedly connected to one end of the inner wall of the control cylinder 452. Two support blocks 412 are fixedly connected to one end of the control cylinder 452. The end of the support block 412 is fixedly connected to the surface of the spring switch button 454. A pull block 413 is fixedly connected to the top of the pad 48, and the surface of the pull block 413 is slidably connected to the inner wall of the base 3.

[0035] A spring-loaded switch button 454 is a controller with a spring, typically consisting of one or more metal springs and an adjustable contact. When an external force is applied to the spring, the contact changes state, thereby controlling the circuit. Specifically, when the button is pressed, the spring on the button is compressed, causing the internal electrical contacts to connect, closing the circuit and allowing current to flow; when the button is released, the spring returns to its original state, the electrical contacts separate, and the circuit is broken, thus achieving on / off control. The spring-loaded switch button 454 is wired to an electric actuator 44.

[0036] The sealing frame 42, anti-slip pad 43 and abutment pad 48 are all rubber components.

[0037] In this embodiment of the utility model, after the grating blade is inserted into the base 3, the pull block 413 is loosened, and the elastic force of the spring piece 49 pushes the pad 48 to move and flexibly contact the surface of the grating blade. The liquid storage cylinder 41 moves on the surface of the sealing frame 42, so that the hydraulic oil inside the liquid storage cylinder 41 is pushed into the control cylinder 452 through the hose 451. Excess hydraulic oil in the control cylinder 452 pushes the moving rod 453 to move and squeezes the third spring 410. The moving rod 453 moves to contact one end of the spring switch button 454 and presses it. After the spring switch button 454 is pressed and energized, it automatically closes the electric push rod 44, so that the anti-slip pad 43 flexibly contacts the end of the grating blade with equal pressure.

[0038] In this embodiment of the utility model, the electric push rod 44 is automatically closed by means of the hose 451, control cylinder 452, moving rod 453 and spring switch button 454, so that the anti-slip pad 43 flexibly presses against the end of the grating blade. The grating blade is flexibly clamped by the spring piece 49 and the abutment 48, which ensures the stability of the grating blade installed in the base 3.

[0039] In some embodiments, such as Figure 1-2 As shown, in a preferred embodiment of the present invention, the adjustment mechanism 2 includes lead screws 22 that are rotatably connected to the inner wall of the base 1 and are evenly distributed. The lower end of the inner wall of the base 3 is threaded to the surface of the lead screws 22. One end of the lead screws 22 is fixedly connected to a servo motor 21, and the surface of the servo motor 21 is fixedly connected to one side of the base 1.

[0040] In this embodiment of the utility model, when it is necessary to adjust the position of the grating blade on the base 1, one of the servo motors 21 is manually turned on. The output shaft of one of the servo motors 21 rotates, driving one of the lead screws 22 to rotate. The rotating lead screw 22 drives the base 3 and the grating blade to move to the corresponding position on the base 1. One of the servo motors 21 is then manually turned off.

[0041] It should be noted that the base 1, servo motor 21, lead screw 22, base 3, liquid reservoir 41, electric push rod 44 and spring switch button 454 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 21, electric push rod 44 and spring switch button 454 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
