Description

Technical Field

[0001] This utility model relates to the field of sensor debugging equipment technology, and in particular to a debugging device for an eddy current displacement sensor. Background Technology

[0002] Eddy current displacement sensors are high-precision non-contact measuring tools widely used in industrial production for precise monitoring of key parameters such as shaft vibration and displacement of large rotating machinery. To ensure the measurement accuracy of these sensors during installation, inspection, and daily maintenance, a dedicated eddy current displacement sensor calibration device must be used for calibration and parameter setting.

[0003] Existing debugging devices are typically designed as portable instruments, and their structure necessarily includes a display screen for showing data and parameters, as well as operation buttons for performing operations. However, the main use environment for these debugging devices is not a clean laboratory, but a complex industrial site, such as a workshop, factory or outdoor equipment platform.

[0004] In these complex industrial sites, commissioning equipment inevitably faces various potential risks. On the one hand, the site environment is crowded and the tools are complicated, and the commissioning equipment is very easy to be bumped during carrying or use. The display screen on the front of its outer wall is a precision and fragile component, which will be damaged once it is hit, resulting in high maintenance costs and delays in the project schedule.

[0005] On the other hand, the lighting conditions in industrial sites or outdoor environments are often very abundant or complex. When operators use debugging devices under strong light, the light will shine directly on the surface of the display screen, producing strong reflections. This makes it difficult to read the debugging values ​​and waveforms on the screen clearly. In order to see the screen clearly, operators have to repeatedly adjust the angle or find a shield, which seriously affects the efficiency and accuracy of the debugging work.

[0006] Therefore, this utility model proposes an eddy current displacement sensor debugging device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology of eddy current displacement sensor debugging devices, such as exposed display screens and buttons that are easily damaged by bumps in industrial sites, and unclear readings due to reflection in strong light environments, this utility model aims to provide an eddy current displacement sensor debugging device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an eddy current displacement sensor debugging device, including: a main body, a display screen fixedly connected to the front side of the outer wall of the main body, and a protective cover fixedly connected to the front side of the outer wall of the main body.

[0009] The outer wall of the protective cover protrudes from the outer wall of the main body at least above and on both sides of the display screen.

[0010] Furthermore, the protective cover is fixedly connected to the display screen and the main body, so that the protruding structure of the protective cover can provide effective physical protection for the display screen, preventing damage to the device due to accidental bumps during transportation or on-site use. At the same time, the structure can block light for the display screen in outdoor or strong light environments, ensuring that the operator can clearly see the numerical display on the screen.

[0011] Preferably, the outer walls of the main body are rotatably connected to handles on both sides. The handles are used to adjust the pitch angle of the front side of the outer walls of the main body, so that the operator can adjust the display screen to the best observation and operation angle under different working heights or different light angles.

[0012] Preferably, as a further limitation on the throttle structure, an anti-slip groove is provided in the middle of the outer wall of the throttle to increase the operating friction, and a damping shaft structure is provided between the throttle and the main body to achieve angular positioning after rotation and stable hovering at any angle.

[0013] Preferably, it also includes a composite heat dissipation structure, with heat dissipation fins on both sides of the outer wall of the main body to increase the passive heat dissipation area. At the same time, a fixing box is fixedly connected to the outer wall of the main body, and a fan is fixedly connected to the middle of the inner wall of the fixing box for active forced air cooling. The combination of the two ensures the stability of the device during long-term operation.

[0014] Preferably, as a further improvement to the heat dissipation structure, a dustproof mesh is fixedly connected to the front side of the inner wall of the fixed box. The dustproof mesh is located on the air intake side of the fan and is used to effectively block and filter dust and impurities from entering the main body when the fan draws in cooling air, thus protecting the internal precision components.

[0015] Preferably, it also includes a data receiving module, with a fixed frame fixedly connected to the top of the outer wall of the main body, a receiving box fixedly connected to the top of the outer wall of the fixed frame, and a data interface fixedly connected to the right side of the outer wall of the receiving box for the access of external sensor signals.

[0016] Preferably, in order to achieve a stable installation of the receiver box, L-shaped fixing plates are fixedly connected to both sides of the outer wall of the receiver box, and fixing holes are correspondingly opened on both sides of the outer wall of the fixing frame to provide a reference for the installation of the L-shaped fixing plates.

[0017] Preferably, as a specific implementation of the receiver box fixing method, the L-shaped fixing plate detachably fixes the receiver box to the fixing frame by means of fasteners passing through the fixing holes. This structure is firmly and reliably connected and facilitates subsequent maintenance and replacement.

[0018] Preferably, to improve the portability of the device, a handle is fixedly connected to the rear side of the outer wall of the main body. The handle has a U-shaped structure to facilitate the operator to hold and carry the device in the industrial field.

[0019] Preferably, the front side of the outer wall of the main body is also provided with operation buttons, which are located below the display screen and are also protected by a protective cover to prevent the operation buttons from being bumped or accumulating dust; the front side of the outer wall of the main body is also provided with a data port to provide additional or backup data access methods.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problem that the display screen and buttons of the existing debugging device are exposed and easily damaged by bumps and knocks, and that the values ​​are difficult to see under strong light by fixing a protective cover to the front side of the outer wall of the main body, and the outer wall of the protective cover protrudes from the outer wall of the main body. It achieves the effect of simultaneously realizing physical protection and sunshade, improving the durability of the equipment and the clarity of the readings.

[0021] 2. This utility model solves the problem of fixed observation angle of existing debugging devices and inconvenience in observation and operation when used at different working heights by rotating handles connected to both sides of the outer wall of the main body. It achieves the effect of allowing users to adjust the screen tilt angle at will and improving the ergonomic convenience.

[0022] 3. This utility model solves the problems of low heat dissipation efficiency leading to unstable operation and easy dust inhalation causing internal damage in existing devices by setting heat dissipation fins on the outer wall of the main body and setting a fixed box with a fan, and setting a dustproof net on the air inlet side of the fixed box. It achieves the effect of combining passive heat dissipation and active air cooling, while taking into account dust prevention, resulting in efficient and stable heat dissipation and extending the service life of the instrument.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. 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.

[0026] Example: Please refer to Figures 1 to 4 This utility model provides an eddy current displacement sensor debugging device, which aims to solve the problem that when existing eddy current displacement sensor debugging devices are used in industrial fields, the display screen 8 lacks effective physical protection and light shielding measures, making it susceptible to damage from impacts or unclear readings due to excessive light.

[0027] like Figure 1 and Figure 3 As shown, an eddy current displacement sensor debugging device includes a main body 1, which serves as the basic frame and mounting carrier of the entire device. Multiple precision components are fixedly connected inside the main body 1, and a display screen 8 is fixedly connected to the front of the outer wall of the main body 1. The display screen 8 is used to intuitively display the debugging values.

[0028] To solve the above-mentioned technical problems, the core structure of this embodiment is as follows: a protective cover 7 is fixedly connected to the front side of the outer wall of the main body 1. The outer wall of the protective cover 7 protrudes from the outer wall of the main body 1. Specifically, the outer wall of the protective cover 7 protrudes from the outer wall of the main body 1 at least above and on both sides of the display screen 8, so that the protective cover 7 can provide effective physical protection for the display screen 8 and prevent the display screen 8 from being damaged by accidental bumps during transportation or on-site use. At the same time, the protruding structure of the protective cover 7 can block the light for the display screen 8 in outdoor or strong light environments, ensuring that the operator can see the numerical display on the screen clearly.

[0029] To further improve the ease of use of the device on site, please refer to... Figure 1 and Figure 3The outer walls of the main body 1 are rotatably connected to the handles 10 on both sides. The handles 10 are used to adjust the pitch angle of the front side of the outer wall of the main body 1 so that the operator can observe the display screen 8 at different heights. In order to increase the friction during adjustment and ensure the stability of the angle, the outer wall of the handle 10 is provided with an anti-slip groove, and a damping shaft is provided between the handle 10 and the main body 1 to achieve angle positioning. To ensure the long-term stable operation of the precision components inside the device, this embodiment also incorporates a composite heat dissipation structure. Please refer to [reference needed]. Figure 1 and Figure 4 Heat dissipation fins 15 are provided on both sides of the outer wall of the main body 1. The heat dissipation fins 15 are used to increase the contact area between the main body 1 and the outside air to achieve passive heat dissipation. At the same time, a fixed box 12 is fixedly connected to the outer wall of the main body 1. A fan 16 is fixedly connected to the middle of the inner wall of the fixed box 12. The fan 16 is used for forced air cooling to actively expel internal heat. In order to prevent dust in the industrial site from being sucked in by the fan 16, a dustproof net 13 is fixedly connected to the front side of the inner wall of the fixed box 12, that is, the air intake side of the fan 16. The dustproof net 13 is used to filter impurities in the air and block dust from entering the interior of the main body 1. Please refer to Figure 1 On the front side of the outer wall of the main body 1, below the display screen 8, there is also an operation button 11. The operation button 11 is also protected by the protective cover 7 and is used by the user to perform function operation and parameter setting of the device. The front side of the outer wall of the main body 1 is also provided with a data port 9, which is also used for data transmission of external components.

[0030] In a preferred embodiment, in order to achieve stable reception and processing of eddy current sensor signals and ensure the firmness of the installation of related components, a fixing frame 2 is fixedly connected to the top of the outer wall of the main body 1, a receiving box 3 is fixedly connected to the top of the outer wall of the fixing frame 2, and a data interface 6 is fixedly connected to the right side of the outer wall of the receiving box 3. The data interface 6 is used for external components to connect with the receiving box 3 to transmit data. At the same time, L-shaped fixing plates 5 are fixedly connected to both sides of the outer wall of the receiving box 3, and fixing holes 4 are correspondingly opened on both sides of the outer wall of the fixing frame 2. The L-shaped fixing plates 5 and the fixing holes 4 are fixed by bolt connection, thereby firmly installing the receiving box 3 on the fixing frame 2. This structural design not only ensures the reliability of the connection, but also facilitates the subsequent disassembly and maintenance of the receiving box 3. As another preferred embodiment, in order to improve the portability of the device when it is moved and operated in the industrial field, a handle 14 is fixedly connected to the rear side of the outer wall of the main body 1. The handle 14 is fixed to the main body 1 in a U-shaped structure. This structure conforms to the ergonomic design, making it convenient for operators to pick up or move the instrument through the handle 14, thus increasing the flexibility of use.

[0031] Working principle: The operator carries the device to the site through the handle 14 on the rear side of the outer wall of the main body 1, and connects the external sensor through the data interface 6 on the receiver box 3 on the top of the fixed frame 2. The receiver box 3 is fixedly attached to the fixed frame 2 by bolts to the L-shaped fixing plate 5 and the fixing hole 4. At the same time, the data jack 9 on the front side of the main body 1 also provides data access. During debugging, the operator can adjust the pitch angle of the main body 1 by rotating the handles 10 on both sides of the main body 1 and using the positioning function of the damping shaft, so as to clearly observe the values ​​on the display screen 8 at different heights. The display screen 8 and the operation buttons 11 below it are all within the protection range of the protective cover 7. The protruding outer wall structure of the protective cover 7 can effectively prevent bumps and block the light of the display screen 8 under strong light. During long-term operation of the device, the heat generated inside is passively dissipated through the heat dissipation fins 15 on the outer wall of the main body 1. At the same time, the fan 16 on the inner wall of the fixed box 12 is activated for active forced air cooling. Air is drawn in through the dust filter 13, which filters out dust and impurities. The cooled air is then accelerated by the fan 16 to remove heat, ensuring the stable operation of the precision components inside the device.
