Description

Technical Field

[0001] This application relates to the field of precision measurement technology, and in particular to a gap displacement measuring device. Background Technology

[0002] In high-end industries such as precision manufacturing, automation control, automotive manufacturing, aerospace, and semiconductors, the clearances between key components are typically minute. The initial dimensional accuracy and stability of these clearances during service directly determine the equipment's operational performance, control precision, and long-term reliability. For example, even a slight deviation in the clearance between the four doors and two hoods of a car and the body can lead to poor sealing, abnormal noise, or increased aerodynamic drag; variations in the clearance of semiconductor chip packages can affect heat dissipation efficiency and electrical connection stability; and fluctuations in the clearance between aero-engine blades and the casing can cause aerodynamic losses or even structural interference, resulting in serious safety hazards.

[0003] However, traditional feeler gauge measurement methods rely on manual operation, which is not only inefficient and highly subjective, but also unable to achieve dynamic real-time monitoring, and the measurement accuracy is greatly affected by the operator's experience. In addition, although precision measuring equipment such as laser interferometry and capacitive displacement sensors can achieve micron-level accuracy, they have complex structures, high purchase and maintenance costs, strict requirements for the measurement environment, and are limited by installation space, making them difficult to adapt to gap measurement in confined spaces or on irregular surfaces. Utility Model Content

[0004] In view of this, this application provides a gap displacement measuring device, which has a simple structure, controllable cost, high measurement accuracy and convenient installation and operation.

[0005] This application provides a gap displacement measuring device, the gap displacement measuring device comprising: A reference element, used to be fixed to the surface of the object being measured to provide a reference datum, wherein the surface of the reference element is printed with codes, reference points, reference lines, and scale line values; and A measuring component is provided for aligning with the reference piece and taking readings. The measuring component includes a handheld magnifying glass, a multi-point positioning plate, and a multi-functional precision ruler. The multi-functional precision ruler includes a ruler body, a positioning base, a built-in magnifying glass, and positioning contacts. The positioning base is fixed to one end of the ruler body. The built-in magnifying glass is embedded in the middle of the ruler body. The positioning contacts are located at the tip of the ruler body and are used for positioning against the reference line. The ruler body is used to read the spacing of the reference line.

[0006] The handheld magnifying glass has a non-slip grip and a magnification of 10-30 times. It is used to assist in observing minute marks on a reference piece and measuring alignment details.

[0007] The multi-point positioning plate is provided with positioning holes, which are set to correspond to the reference points of the reference component, and are used to position the measuring component at different measuring points.

[0008] The scale accuracy of the ruler body is consistent with that of the reference component.

[0009] The built-in magnifying glass is coaxially aligned with the scale lines on the ruler body. The magnification of the built-in magnifying glass is 5-20 times, which is used to clearly magnify and display the scale values ​​and the alignment of the baseline.

[0010] The positioning contact is a conical or needle-shaped structure used to precisely align with the reference line on the reference component.

[0011] The gap displacement measuring device provided in this application allows the reference component to be directly attached to the surface of objects of different shapes, making installation and operation convenient and cost-effective. Furthermore, the printed codes and reference points on its surface provide a stable and clear reference for subsequent measurements, solving the problems of complex installation and difficulty in adapting to irregularly shaped surfaces associated with traditional reference components. Simultaneously, the positioning contacts of the multi-functional precision scale are aligned with the reference line, and the dual magnification structure, combining a built-in magnifying glass and a handheld magnifying glass, effectively magnifies scale details, significantly reducing manual reading errors and compensating for the insufficient precision of traditional feeler gauges and other tools. This gap displacement measuring device can support the measurement of minute gaps, effectively adapting to the diverse measurement needs of precision manufacturing, automotive, semiconductor, and other fields.

[0017] Please see Figure 1 and Figure 2 This application provides a gap displacement measuring device 1, which includes a reference component 10 and a measuring component 20. The reference component 10 is used to fix itself to the surface of the object being measured to provide a reference benchmark. The surface of the reference component 10 is printed with codes, reference points, reference lines, and scale line values. The measuring component 20 is used to align with the reference component 10 and take readings. The measuring component 20 includes a handheld magnifying glass 21, a multi-point positioning plate 22, and a multi-functional precision ruler 23. The multi-functional precision ruler 23 includes a ruler body, a positioning base, a built-in magnifying glass 231, and a positioning contact 232. The positioning base is fixed to one end of the ruler body. The built-in magnifying glass 231 is embedded in the middle of the ruler body. The positioning contact 232 is located at the tip of the ruler body and is used to align with the reference line for positioning. The ruler body is used to read the spacing of the reference line.

[0018] Optionally, the surface of the reference component 10 is marked with codes, reference points, reference lines and scale line values ​​through a printing process, and the material is selected from waterproof stickers, self-adhesive stickers or transparent films.

[0019] Optionally, the encoding uses a QR code or barcode to identify information about the reference component 10, facilitating data traceability. The reference point serves as a positioning reference and is represented by a solid black dot.

[0020] Optionally, the scale lines and values ​​are printed along the extension direction of the baseline, with a scale accuracy of 0.01mm-0.1mm, a value marking interval of 1mm, and clear black font to ensure clear readings.

[0021] Optionally, the reference element 10 can be directly attached to the surface of the object being measured, such as the mating surface of an automobile door cover or the packaging surface of an electronic component. After attachment, the plane where the reference line is located is parallel to the end face of the gap being measured, forming a stable measurement reference.

[0022] In summary, the gap displacement measuring device 1 provided in this application allows the reference component 10 to be directly attached to the surface of objects of different shapes, making installation and operation convenient and cost-effective. Furthermore, the printed codes and reference points on its surface provide a stable and clear reference for subsequent measurements, solving the problems of complex installation and difficulty in adapting to irregularly shaped surfaces associated with traditional reference components 10. Simultaneously, the positioning contact 232 of the multi-functional precision scale 23 is aligned with the reference line, and the dual magnification structure, combined with the built-in magnifying glass 231 and the handheld magnifying glass 21, effectively magnifies scale details, significantly reducing manual reading errors and compensating for the insufficient precision of traditional feeler gauges and other tools. The gap displacement measuring device 1 can support the measurement of minute gaps, effectively adapting to the diverse measurement needs of precision manufacturing, automotive, semiconductor, and other fields.

[0023] In one specific embodiment of this application, the gap displacement measuring device 1 can be used to measure the gap of a semiconductor chip package. The scale accuracy of the reference piece 10 is 0.01 mm, the built-in magnifying glass 231 of the measuring component 20 has a magnification of 12x, and the tip diameter of the positioning contact 232 is 0.05 mm. During the measurement process, the reference piece 10 is attached to the end face of the chip package shell to measure its initial measurement gap. After being subjected to a load, the gap is measured again, thus achieving accurate measurement of minute gap load displacement changes.

[0024] Please refer to it again. Figure 1 The handheld magnifying glass 21 has a non-slip grip and a magnification of 10-30 times. The handheld magnifying glass 21 is used to assist in observing tiny marks on the reference piece 10 and measuring alignment details.

[0025] Optionally, the lens material of the handheld magnifying glass 21 is optical glass.

[0026] In this embodiment, the handheld magnifying glass 21 is equipped with an anti-slip grip, which increases the friction between the hand and the lens. Even during prolonged measurements, when hands are slightly sweaty, or in slippery environments, the magnifying glass can be held stably, preventing observational deviations due to slippage and ensuring consistency in alignment and reading processes. Furthermore, the handheld magnifying glass 21 has a magnification of 10-30x, enabling clearer presentation of minute codes, fine reference points, and scale details on the reference piece 10, further improving measurement accuracy.

[0027] Please refer to it again. Figure 1 The multi-point positioning plate 22 is provided with positioning holes, which are set to correspond to the reference points of the reference component 10, and are used to position the measuring component 20 at different measuring points.

[0028] Optionally, the multi-point positioning plate 22 is a rectangular flat plate structure with at least two positioning holes on its surface. The positions of the positioning holes correspond one-to-one with the reference points on the reference component 10, which is used to accurately position the reference component 10 before measurement, ensuring the accuracy of the fit of the reference component 10. Furthermore, before measurement, only the positioning holes need to be aligned with the reference points to complete the reference calibration, eliminating the need for complex auxiliary positioning tools or professional operating skills, thus improving measurement efficiency.

[0029] Please refer to it again. Figure 1 The scale accuracy of the ruler body is consistent with that of the reference component 10.

[0030] Optionally, the scale body is made of stainless steel, with a length of 50mm-100mm, and the surface is treated with anti-corrosion to ensure long-term accuracy.

[0031] In this embodiment, the scale body and the reference component 10 adopt the same scale accuracy, which avoids the problem of disconnect between the reference accuracy and the reading measurement accuracy caused by the mismatch of their accuracy, eliminates system-level measurement errors, and ensures that the read baseline spacing data can truly reflect the actual size and displacement change of the measured gap.

[0032] Please refer to it again. Figure 2 The built-in magnifying glass 231 is coaxially aligned with the scale lines on the ruler body. The magnification of the built-in magnifying glass 231 is 5-20 times, used to clearly magnify and display the scale values ​​and the alignment of the baseline.

[0033] Optionally, the positioning seat is fixedly connected to one end of the ruler body, and the inner side wall of the positioning seat is provided with an anti-slip rubber pad, which is used to position the ruler body on the surface of the object being measured during measurement and to prevent slippage during the measurement process.

[0034] Optionally, the built-in magnifying glass 231 is embedded in the middle of the ruler body, with the center of the magnifying glass's field of view aligned with the scale lines of the ruler, for clearly reading the distance values ​​between the reference lines on the reference piece 10.

[0035] In this embodiment, the built-in magnifying glass 231 is coaxially aligned with the scale lines, ensuring that the center of the magnifying glass's field of view is precisely aligned with the scale lines and the reference line of the reference component 10. This solves the parallax error problem caused by observation angle deviation in traditional non-coaxial magnifying glasses. Accurate values ​​can be read without repeatedly adjusting the observation angle during measurement, minimizing the reading error related to the alignment of the scale values ​​with the reference line and further ensuring the numerical accuracy of minute gap measurements.

[0036] Please refer to it again. Figure 1 and Figure 2 The positioning contact 232 has a conical or needle-shaped structure and is used to precisely align with the reference line on the reference member 10.

[0037] Optionally, the positioning contact 232 is located at the tip of the ruler body and is a downwardly convex conical structure, used to accurately fit and position with the reference line on the reference component 10, ensuring that the scale reference of the ruler is aligned with the reference line of the reference component 10 when measuring.

[0038] In this embodiment, the tip of the positioning contact 232 with a conical or needle-like structure has a very small contact surface, which can accurately fit the thin reference line on the reference member 10, avoid the problem of misalignment, realize the point-to-point accurate positioning of the reference line, and reduce positioning deviation.
