Description

Technical Field

[0001] This utility model belongs to the field of data measurement and analysis technology, and specifically relates to a novel portable metal straight wire chamfering measuring device. Background Technology

[0002] In the field of machining, chamfering the ends of metal materials is a common process, and accurate measurement of its dimensions (including angles and lengths) is crucial for product quality control. For large-diameter metal bars (e.g., diameter ≥ 10mm), a specially designed chamfering ruler is typically used for measurement. This type of tool, by fitting snugly against the chamfered end of the bar, allows for direct reading of angle and length parameters. It is easy to operate and has minimal measurement error, meeting the measurement needs of large-diameter bars.

[0003] However, existing technologies have significant limitations for chamfering measurements of small-diameter straight metal wires (such as Φ3-Φ6mm): First, the small diameter and high flexibility of small wires make it difficult for the measuring surface of traditional chamfering rulers to effectively align with the chamfer at the wire end, leading to easy slippage or displacement of the contact point and a significant increase in angle and length measurement errors (angle errors often exceed 1°, and length errors exceed 0.2mm); Second, small wires are prone to deformation during measurement due to external forces (such as slight force applied when holding the wire), causing the chamfer position to shift and further affecting measurement accuracy; Third, the chamfer area at the end of small wires is small. The scale accuracy of traditional tools (usually 1° or 0.5mm) cannot meet the high-precision measurement requirements of small-sized chamfers (such as angle error ≤0.5°, length error ≤0.1mm); fourth, the machining site has high requirements for the portability and ease of operation of measuring tools, but the existing measuring equipment for small wires is mostly benchtop precision instruments, which are large and heavy, making it difficult to use directly at the machining station; while portable tools have problems such as single function (only measuring angle or length) and need for manual reading (which easily introduces human error), which cannot meet the needs of efficient and high-precision measurement on site.

[0004] In summary, there is currently a lack of dedicated chamfering measuring devices for small-gauge straight metal wires with diameters of Φ3-Φ6mm on the market. Traditional tools have poor applicability and low accuracy, while precision instruments lack portability and ease of operation. As a result, measuring the chamfering dimensions of small wires has become a technical challenge in the field of machining, which urgently needs to be addressed. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel portable metal straight wire chamfering measuring device, comprising a base, a V-groove material platform on the top of the base, multiple sets of clamping platforms on both sides of the V-groove material platform, and a spring pressure plate on each set of clamping platforms; a lens mounting bracket is fixedly mounted at the end of the base, an industrial camera is mounted on the bottom of the lens mounting bracket, a zoom knob is provided on the industrial camera, and an LED light panel is provided on the top of the lens mounting bracket;

[0006] It also includes a control module and an LCD screen. The control module is mounted on the base and connected to the LED light board and the industrial camera cable. The LCD screen is fixedly mounted on the base and connected to the industrial camera cable.

[0007] As a further improvement of this utility model, a metal wire to be tested is placed in the V-groove material platform, and the spring pressure plate is used to press and fix the metal wire.

[0008] As a further improvement of this utility model, the chamfered position of the end of the metal wire is located directly above the industrial camera.

[0009] As a further improvement of this utility model, the control module includes a power switch, a light adjustment knob, and a camera button;

[0010] The power switch is electrically connected to the industrial camera, the LED light board, and the LCD screen, respectively.

[0011] The light adjustment knob is electrically connected to the LED light panel;

[0012] The photo button is electrically connected to the industrial camera.

[0013] As a further improvement of this utility model, the zoom knob includes three settings: 5x, 10x, and 20x.

[0014] As a further improvement of this utility model, the liquid crystal display screen also has a built-in analysis module, which is used to measure the chamfer data of the displayed image and output the data.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Addressing the challenges of fixing small-diameter, fine metal wires (Φ3-Φ6mm) due to their small diameter and high flexibility, as well as the significant measurement errors of traditional chamfer rulers, this device utilizes a V-groove material stand with spring pressure plates to effectively solve the wire fixing problem, ensuring wire stability during measurement. An industrial camera combined with a multi-level zoom knob (5x, 10x, 20x) clearly captures the chamfer details at the wire ends, adapting to different measurement scenarios and significantly improving measurement accuracy. An adjustable-brightness LED light panel ensures image quality and further optimizes image clarity. The built-in analysis module's LCD screen processes image data captured by the industrial camera in real time, automatically calculating and displaying the chamfer angle and length. It also supports automatic recording of measurement data and comparison with historical data, facilitating process optimization. The device is simple and efficient, meeting the high-precision measurement needs of small-diameter wire chamfer dimensions in machining operations and effectively improving on-site work efficiency.

After the metal wire 1 is pressed and fixed, the power is turned on by the control module, and the brightness of the LED light board is adjusted to ensure that the industrial camera 7 captures a clear chamfer image. At the same time, the appropriate magnification is selected by rotating the zoom knob 6 so that the chamfer image is clearly displayed on the LCD screen 8.

[0027] Optionally, the chamfered end of the metal wire 1 is positioned directly above the industrial camera 7 to improve the illumination effect of the LED light panel 4 on the chamfered end of the metal wire 1, ensuring clear image details. Simultaneously, this ensures high-resolution imaging by the industrial camera 7, facilitating subsequent analysis of the chamfer parameters and improving measurement accuracy.

[0028] Optionally, the control module includes a power switch 11, a light adjustment knob 10, and a photo button 9; the power switch 11 is electrically connected to the industrial camera 7, the LED light board 4, and the LCD screen 8 respectively; the light adjustment knob 10 is electrically connected to the LED light board 4; and the photo button 9 is electrically connected to the industrial camera 7.
