Description

Technical Field

[0001] This utility model relates to the field of mechanical parts manufacturing technology, and in particular to an electronic inspection tool for detecting the deformation of curved surfaces of parts. Background Technology

[0002] With the upgrading of consumption and the development of intelligent manufacturing, taking the automotive manufacturing industry as an example, many curved structural components, such as dashboards, HUD covers, door panels, and seats, are showing a trend of increasing complexity, lightweighting, and multi-material integration. Their geometric accuracy directly affects the adaptability of the products. Traditional inspection methods are no longer sufficient to meet industry needs, mainly due to the low efficiency of offline inspection. Relying on coordinate measuring machines (CMMs) or manual inspection tools, products need to be taken from the production line to the laboratory for inspection, with a single inspection taking several hours or even days, and the inspection results cannot be fed back in real time. The quantitative inspection capability for complex curved surfaces is insufficient. Contact-type inspection tools (such as plug gauges and templates) can only judge "pass / fail" and cannot accurately quantify the amount of deformation (such as the depth of surface indentation and edge warping). For irregular curved surfaces, traditional 2D visual inspection is prone to missing edge defects, while manual visual inspection is affected by the texture of leather embossing, making it difficult to identify tiny scratches or wrinkles, and even more so, it cannot quantify the amount of deformation. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention aims to provide an electronic inspection tool for detecting the deformation of curved surfaces of parts.

[0004] The technical solution adopted in this utility model is as follows: An electronic inspection tool for detecting the surface deformation of a part includes a frame mechanism, a detection mechanism, and a positioning and zeroing mechanism. The frame mechanism comprises a support frame, a desktop, a touch screen, a light source, a display screen, a tri-color light, a printer, an electrical control cabinet, a start button, and a reset button. The desktop, touch screen, light source, display screen, tri-color light, printer, and electrical control cabinet are all mounted on the support frame. The start button and reset button are fixedly mounted on the desktop. The detection mechanism includes a guide post, a spring, a sensor, an adjusting screw, a base, an adjusting plate, a fixing plate, and a wiring conduit. One side of the sensor is the detection side. The base has a functional inclined surface and is fixed to the desktop of the frame mechanism. The adjusting plate and the fixing plate are both L-shaped. One side of the adjusting plate has a concave-convex positioning structure corresponding to the sensor, and the other side has an adjusting screw hole and a mounting hole. One side of the fixing plate has a guide hole and a screw hole, and it is fixed to the functional inclined surface of the base through the other side. One end of the guide post is fixed in the mounting hole of the adjusting plate, and the spring is mounted on the guide post. They are slidably mounted together through the guide post. In the guide hole of the fixed plate, the spring abuts against the folded edge of one side of the fixed plate and the folded edge of the other side of the adjusting plate. The adjusting screw moves through the adjusting screw hole of the folded edge of the other side of the adjusting plate and is screwed into the screw hole of the folded edge of the fixed plate. The sensor is fixed to the concave-convex positioning structure of the folded edge of the adjusting plate. The wiring conduit is connected to the sensor. The positioning and zeroing mechanism includes a rear positioning post, a front positioning post, a zeroing block, a zeroing seat, an adjusting shim, a base, a quick clamp, and a reference seat. The adjusting shim is fixed to the tabletop of the frame mechanism and fixed to the upper part of the base. The zeroing seat has a positioning protrusion and a screw hole on its upper part and is fixed to the upper part of the adjusting shim. The zeroing block has a contoured surface according to the curved shape of the product and has a positioning hole corresponding to the positioning protrusion of the zeroing seat. It also has a connecting hole corresponding to the screw hole of the zeroing seat. The zeroing block is fixed to the upper part of the zeroing seat by screws through the connecting hole.

[0005] The electronic inspection tool for detecting the surface deformation of a part is characterized in that the sensor is a high-precision laser sensor.

[0006] The electronic inspection tool for detecting the surface deformation of a part is characterized in that the frame mechanism further includes rollers, which are installed at the bottom of the support frame of the frame mechanism.

[0007] The electronic inspection tool for detecting the surface deformation of a part is characterized in that at least three reference bases are configured and fixedly installed on the table of the frame mechanism.

[0008] This utility model presents an electronic inspection tool for detecting the surface deformation of parts. It features a novel design, scientific structure, and safe and reliable operation. Its advantages are concentrated in three main dimensions: improved inspection accuracy and efficiency, reduced cost risks, and unlocked data value. It addresses the core pain points of traditional inspection tools and can be applied to the entire production process. 1. Higher precision: From "qualitative judgment" to "quantitative accuracy" Traditional inspection tools rely on feeler gauges, feeler gauges, and dial indicators for measurement, which have low accuracy. In contrast, electronic inspection tools can achieve micron-level quantitative detection through sensors such as lasers and vision.

[0009] 2. Faster efficiency: From "offline waiting" to "online real-time" Electronic inspection fixtures can be integrated into the production line to achieve real-time inspection within seconds. Simultaneously, data is automatically uploaded to MES systems, eliminating the need for manual recording and analysis, and significantly improving inspection efficiency compared to traditional methods.

[0010] 3. Reduce reliance on human intervention: From "experience-based judgment" to "objective standards" Electronic inspection tools, through AI algorithms and non-contact inspection, not only have stable accuracy but also avoid human-caused damage, while reducing reliance on "senior quality inspectors" and lowering personnel training costs.

[0011] 4. Data Traceability: From "Results Archiving" to "Process Optimization" Electronic inspection fixtures can automatically store the inspection data of each workpiece (such as deformation, defect location, and inspection time), and support historical traceability and trend analysis, thereby enabling process optimization.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain this utility model. Key terms that need attention in these descriptions, including "zero-calibration block," "contour surface," "functional inclined surface," and "detection side," are only for the purpose of facilitating a concise and clear description of this utility model and should not be construed as limiting the scope of this utility model.

[0015] like Figure 1-3 As shown, this utility model discloses an electronic inspection tool for detecting the surface deformation of parts, comprising a frame mechanism K, a detection mechanism J, and a positioning and zeroing mechanism X. The frame mechanism K includes a support frame, a desktop, a touch screen 1, a lighting lamp 2, a display screen 3, a tri-color light 4, a printer 5, an electrical control cabinet 7, a start button 10, a reset button 11, and rollers 19. The quick clamp 18 is commercially available. The desktop, touch screen 1, lighting lamp 2, display screen 3, tri-color light 4, printer 5, and electrical control cabinet 7 are all mounted on the support frame. The rollers 19 are mounted at the bottom of the support frame to facilitate the movement of the frame mechanism K. The start button 10 and reset button 11 are fixedly mounted on the desktop.

[0016] Referring to Figure 4, the detection mechanism J includes a guide post 12, a spring 13, a sensor 14, an adjusting screw 15, a base 16, an adjusting plate 17, a fixing plate 21, and a wiring conduit 22. Firstly, to ensure detection accuracy, the core component of this invention, the sensor 14, is a high-precision laser sensor in this embodiment, with one side being the detection side 14A. The base 16 has a functional inclined surface and is fixed to the tabletop of the frame mechanism K. Both the adjusting plate 17 and the fixing plate 21 are L-shaped. One side of the adjusting plate 17 has a concave-convex positioning structure corresponding to the sensor 14, and the other side has an adjusting screw hole and a mounting hole. One side of the fixing plate 21 has a guide hole and a screw hole, and is fixed to the functional surface of the base 16 via the other side. On the inclined surface, one end of the guide post 12 is fixed in the mounting hole of the adjusting plate 17, and the spring 13 is mounted on the guide post 12. Together, they slide in the guide hole of the fixing plate 21 through the guide post 12. The spring 13 abuts against the folded edge of one side of the fixing plate 21 and the folded edge of the adjusting plate 17 on the other side. The adjusting screw 15 moves through the adjusting screw hole of the folded edge of the adjusting plate 17 and is screwed into the screw hole of the folded edge of the fixing plate 21. The position of the adjusting plate 17 corresponding to the fixing plate 21 can be adjusted by adjusting the adjusting screw 15. The sensor 14 is fixed in the concave-convex positioning structure of the folded edge of the adjusting plate 17 to ensure installation and usage accuracy. The wiring conduit 22 is connected to the sensor 14 to facilitate wire arrangement and connection. The positioning and zeroing mechanism X includes a rear positioning post 6, a front positioning post 8, a zeroing block 9, a zeroing seat 25, an adjusting shim 26, a base 27, a quick clamp 18, and a reference seat 20. The rear positioning post 6, the front positioning post 8, the base 27, the quick clamp 18, and the reference seat 20 are fixed on the table of the frame mechanism K. The adjusting shim 26 is fixed on the upper part of the base 27. The zeroing seat 25 has a positioning protrusion and a screw hole on its upper part and is fixed on the upper part of the adjusting shim 26. The zeroing block 9 has a contour surface 9A according to the curved shape of the product P, and has a positioning hole 23 corresponding to the positioning protrusion of the zeroing seat 25. It also has a connecting hole 24 corresponding to the screw hole of the zeroing seat 25. The zeroing block 9 is fixed to the upper part of the zeroing seat 25 by screws through the connecting hole 24. The touch screen 1, lighting 2, display screen 3, tri-color light 4, printer 5, electrical control cabinet 7, start button 10, reset button 11, and sensor 14 are connected by electrical wires in a conventional manner.

[0017] In practical applications, the positioning and zeroing mechanism X and the corresponding detection mechanism J, including the rear positioning post 6, the front positioning post 8, the quick clamp 18, the base 16, and the reference base 20, need to be installed and fixed at appropriate positions on the table of the frame mechanism K according to the shape and size of the product P, so as to ensure that the product P is stably fixed during subsequent use, and as... Figure 4As shown, ensure that the contoured surface 9A of the zeroing block 9 corresponds to the detection side 14A of the sensor 14. Following the principle that three points determine a surface, a reference surface is determined using a reference base 20. Therefore, three reference bases 20 fixed on the tabletop of the frame mechanism K are required.

[0018] When this utility model is used, it goes through the following steps: Step 1. Zeroing sensor 14 of zeroing block 9 According to the requirements of the product P to be tested, multiple zeroing blocks 9 are made by conforming to the curved surface of the product P, with at least one zeroing block 9. The conforming surface 9A completely corresponds to the curved surface of the product P. After the zeroing block 9 is made, it is installed on the zeroing seat 25 of the positioning zeroing mechanism X. First, the reference seat 20, which has been previously calibrated, is used as a reference. The electronic gauge is positioned by coordinate marking using a cantilever measuring machine. The zeroing block 9 is measured by marking. The zeroing block 9 is adjusted by adjusting the shims 26. When the measurement result of the zeroing block 9 of the cantilever measuring machine meets the data design requirements, the zeroing block 9 is fixed to the zeroing seat 25, thus completing the zeroing of the zeroing block 9.

[0019] Step 2. Zeroing sensor 14 Turn on the power, initialize and start the device using the reset button 11, trigger the program to run via the touch screen 1, turn on the display screen 3 and the light 2, install the sensor 14 with the morphological surface 9A of the zeroing block 9 corresponding to the detection side 14A, use the zeroing block 9, and observe the zeroing display on the display screen 3 through the adjusting screw 15 of the detection mechanism J, adjust the sensor 14 to the specified position for zeroing, remove the zeroing block 9 after zeroing, and prepare the product for testing.

[0020] Step 3. Product P testing Place product P on the rear positioning stake 6 and the front positioning stake 8. Secure product P in place using the quick-clamp 18. Press the start button 10 to begin testing. The testing mechanism J, based on the laser triangulation principle, displays measurement data from multiple monitoring points simultaneously on the display screen 3, indicating whether the measurement result is OK or NG. If product P passes the test, a label is automatically printed from the printer, and the product testing information is uploaded for easy tracking later. If the test result is NG, the device alerts the operator via a three-color indicator light 4. After testing, release the quick-clamp 18 and remove the product, completing the testing process.

[0021] The above description is merely one embodiment of this utility model. For those skilled in the art, various modifications and variations of this utility model are possible, which will not be elaborated upon here. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection claimed by this utility model.
