AI Technical Summary
In existing technologies, automotive gaskets are prone to slippage and displacement during observation due to slight vibrations or touches, which can interrupt the inspection process. Furthermore, the lack of rotating clamping components makes it impossible to fully observe key areas such as edges and cross-sections, resulting in blind spots in the inspection.
An inverted metallurgical microscope was designed, comprising a shim plane fixing component and a rotating clamping component. The shim plane fixing component is instantly fixed by an elastic specimen clamp, while the rotating clamping component is driven by a servo motor to achieve flexible clamping and angle adjustment, ensuring the best observation angle for the shim edge and cross-sectional tissue.
It enables rapid and stable fixation of the gasket and multi-angle observation, shortens the clamping time, and allows clear observation of the microstructure of key parts, thus improving the integrity and accuracy of the test.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive gasket manufacturing technology, specifically to an inverted metallographic microscope used in automotive gasket manufacturing. Background Technology
[0002] Inverted metallurgical microscopes are crucial microscopic analysis tools in materials science and industrial production. Their objective lens is positioned below the sample, with the observation surface facing downwards, making them suitable for examining thick, irregularly shaped metal samples. Based on optical imaging principles, these microscopes, through high magnification and specialized illumination systems, can clearly reveal the grain morphology, phase distribution, inclusions, and microscopic defects of metallic materials. In the automotive manufacturing industry, inverted metallurgical microscopes are widely used for component quality control, providing a basis for optimizing production processes by analyzing the correlation between material microstructure and properties.
[0003] In existing technologies, the lack of planar fixation means that even slight vibrations or touches during observation can cause the pad to slide or shift on the smooth stage. Once the pad leaves the center of the optical path or the preset observation position, the operator needs to repeatedly stop observation, re-find and reposition the sample, severely disrupting the observation process and making efficient and continuous testing impossible. In addition, existing technologies lack rotating clamping components, so the microscope can only observe the horizontal plane of the pad, and is powerless to observe the edges and cross-sectional structures that are crucial to its performance. The operator cannot obtain clear images of these areas, resulting in an incomplete and superficial assessment of the pad's quality. This may lead to the omission of major quality hazards such as edge microcracks and uneven cross-sectional seepage, making the equipment's observation angle singular and creating blind spots in the detection. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides an inverted metallographic microscope for automotive gasket production. It solves the technical problems in the prior art where slight vibration or touch during observation can cause the gasket to slide or shift on the smooth stage, requiring the operator to repeatedly stop observation, search for and reposition the sample, severely disrupting the observation process and making efficient and continuous testing impossible; and the lack of a rotating clamping component means the microscope can only observe the horizontal plane of the gasket, resulting in a single observation angle and blind spots in the detection.

A gasket plane fixing assembly is disposed on the top of the stage. The gasket plane fixing assembly is used to limit and fix the car gasket that is placed flat on the top of the stage, so as to facilitate microscopic observation of the car gasket in the plane direction. A rotating clamping assembly is disposed on the top of the stage. The rotating clamping assembly is used to flexibly clamp the automotive gasket while adjusting its angle to achieve the optimal observation angle positioning of the automotive gasket's edge and cross-sectional structure.
[0006] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of the present invention, the gasket plane fixing assembly includes a light-transmitting hole, which is opened at the top center of the stage. Fixing posts are fixedly connected to the left and right sides of the top of the stage, and elastic specimen clips are fixedly connected to the outer walls of the left and right fixing posts.
[0007] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, the light-transmitting hole is located directly below the illumination lamp, and the two elastic specimen clips are located on the left and right sides of the light-transmitting hole.
[0008] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, the rotating clamping assembly includes a rotating shaft, which is rotatably connected to the top rear side of the stage. An L-shaped rotating plate is fixedly connected to the outer wall of the rotating shaft. A motor is fixedly connected to the upper rear side wall of the L-shaped rotating plate. The output shaft of the motor passes through the front side wall of the L-shaped rotating plate and is fixedly connected to a toothed pulley. A rotating column is rotatably connected to the bottom of the front side wall of the L-shaped rotating plate. A toothed pulley is fixedly connected to the front end of the rotating column. The outer walls of the toothed pulleys are fitted with synchronous toothed belts that mesh with them.
[0009] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, the first motor is a servo motor and the first motor has a self-locking function.
[0010] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, a hollow cylinder is fixedly connected to the front side of the toothed pulley II, a motor II is fixedly connected inside the hollow cylinder, the output shaft of the motor II passes through the front outer wall of the hollow cylinder and is fixedly connected to a worm gear, and two symmetrical L-shaped fixing rods are fixedly connected to the front side of the hollow cylinder, and a sector-shaped worm wheel is rotatably connected to the bend of each of the two L-shaped fixing rods, and both of the sector-shaped worm wheels are meshed with the worm gear.
[0011] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, a rotating rod 1 is fixedly connected to the outer wall of the left and right fan-shaped worm gears on the side away from the worm. A bent rod is rotatably connected to the ends of the left and right rotating rods that are far apart from each other. A rotating rod 2 is rotatably connected to the front end of the left and right L-shaped fixed rods. The ends of the left and right rotating rods that are far apart from each other are rotatably connected to the left and right bent rods respectively. A pressure sensor is fixedly connected to the opposite surface of the left and right bent rods. An anti-slip rubber pad is fixedly connected to the opposite surface of the left and right pressure sensors.
[0012] For example, in an inverted metallographic microscope for producing automotive gaskets provided in at least one embodiment of this utility model, the second motor is a servo motor, the pressure sensor is electrically connected to the second motor, and the L-shaped fixing rod, the first rotating rod, the bending rod, and the second rotating rod form a parallelogram structure.
[0013] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the gasket plane fixing component allows the operator to simply place the gasket at the designated position on the stage for routine planar observation. The elastic specimen clamp instantly presses and fixes it, eliminating the tedious screw tightening or adjustment steps and significantly shortening the clamping time for a single sample. This is ideal for scenarios requiring rapid, batch testing on production lines. The rotating clamping component allows for precise rotation and fixation of the gasket at any observation angle. This frees the operator from observing only the flat surface of the gasket, enabling focused observation of its edges (e.g., burrs, wear) and cross-sections (e.g., coating thickness, internal grain flow, heat treatment effect). By adjusting to the optimal angle, the microstructure of these critical areas can be revealed more clearly, providing unprecedented three-dimensional structural information. This is crucial for analyzing the gasket's sealing performance, fatigue strength, and process integrity.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] like Figures 1-2 As shown, it illustrates an inverted metallographic microscope for automotive gasket production according to one embodiment of the present invention, comprising: An inverted metallurgical microscope 1 is provided with an illumination lamp 10 fixedly connected to the top of the rear inner wall of the inverted metallurgical microscope 1, a stage 11 fixedly connected to the inside of the inverted metallurgical microscope 1, an objective lens 12 fixedly connected to the inner bottom wall of the inverted metallurgical microscope 1, and an eyepiece 13 fixedly connected to the front side of the inverted metallurgical microscope 1. The gasket plane fixing component 2 is set on the top of the stage 11. The gasket plane fixing component 2 is used to limit and fix the car gasket that is placed flat on the top of the stage 11, so as to facilitate microscopic observation of the car gasket in the plane direction. The rotating clamping assembly 3 is located on the top of the stage 11. The rotating clamping assembly 3 is used to flexibly clamp the automotive gasket while adjusting its angle to achieve the best observation angle positioning of the edge and cross-sectional structure of the automotive gasket.
[0023] In some examples, the inverted metallurgical microscope body 1 (model Nikon Eclipse MA200) adopts a conventional inverted structure, which is internally equipped with an illumination lamp 10, a stage 11, an objective lens 12, and an eyepiece 13. The illumination lamp 10 is fixedly connected to the top of the rear inner wall of the inverted metallurgical microscope 1 to provide uniform illumination as a light source. The stage 11 is fixedly connected to the inside of the inverted metallurgical microscope 1 for placing automotive gasket samples. The objective lens 12 is fixedly connected to the inner bottom wall of the inverted metallurgical microscope 1 for magnifying sample images. The eyepiece 13 is fixedly connected to the front of the inverted metallurgical microscope 1 for user observation. The illumination lamp 10 can be an LED illumination module, such as an OSRAMLDCQ-7P LED lamp, which can provide high brightness and uniform light.
[0024] like Figures 2-3 As shown, it illustrates the gasket plane fixing assembly 2 in another embodiment of the present invention. The gasket plane fixing assembly 2 includes a light-transmitting hole 20, which is opened at the top center of the stage 11. Fixing posts 21 are fixedly connected to the left and right sides of the top of the stage 11, and elastic specimen clips 22 are fixedly connected to the outer walls of the left and right fixing posts 21.
[0025] The light-transmitting hole 20 is located directly below the illumination lamp 10, and two flexible specimen clips 22 are located on the left and right sides of the light-transmitting hole 20.
[0026] In some examples, the gasket plane fixing assembly 2 is located on the top of the stage 11 to limit and fix the car gasket placed flat on the stage 11, ensuring that the gasket is stable in the planar direction and facilitating microscopic observation. Specifically, the light-transmitting hole 20 is opened at the top center of the stage 11, located directly below the illumination lamp 10, allowing light to pass through and illuminate the sample. Two fixing posts 21 are fixedly connected to the top left and right sides of the illumination lamp 10, respectively. Each fixing post 21 has an elastic specimen clip 22 fixedly connected to its outer wall. The elastic specimen clip 22 is made of spring steel and has elastic deformation capability, which can hold car gaskets of different thicknesses. The two elastic specimen clips 22 are located on the left and right sides of the light-transmitting hole 20, pressing the gasket tightly onto the stage 11 by elastic force to prevent movement.
[0027] When routine microscopic observation of the planar structure of an automotive gasket is required, the operator places the automotive gasket sample flat on top of the stage 11, directly above the light aperture 20. At this time, the light emitted by the illumination lamp 10 passes through the light aperture 20 and evenly illuminates the surface of the gasket sample. The elastic specimen clamps 22 located on both sides of the light aperture 20 use their own elastic deformation force to press and fix the automotive gasket onto the stage 11 from both sides, preventing it from moving during observation. After the light passes through the sample, it is captured and magnified by the objective lens 12, ultimately... Imaging is provided for the operator to observe through eyepiece 13. This mode is suitable for rapid and stable detection of features such as the crystal phase and porosity of the gasket plane. In this embodiment, with the gasket plane fixing component 2, when the gasket needs to be observed in a conventional plane, the operator only needs to place the gasket at the designated position on the stage, and the elastic specimen clamp can instantly press and fix it. This "place and fix" method eliminates the tedious screw tightening or adjustment steps, greatly shortens the clamping time of a single sample, and is very suitable for scenarios on the production line that require rapid and batch testing.
[0028] like Figures 2-5 As shown, a rotary clamping assembly 3 is shown in another embodiment of the present invention. The rotary clamping assembly 3 includes a rotary shaft 30, which is rotatably connected to the top rear side of the platform 11. An L-shaped rotary plate 31 is fixedly connected to the outer wall of the rotary shaft 30. A motor 32 is fixedly connected to the upper rear side wall of the L-shaped rotary plate 31. The output shaft of the motor 32 passes through the front side wall of the L-shaped rotary plate 31 and is fixedly connected to a toothed pulley 33. A rotary column 36 is rotatably connected to the bottom of the front side wall of the L-shaped rotary plate 31. A toothed pulley 34 is fixedly connected to the front end of the rotary column 36. A synchronous toothed belt 35 that meshes with the toothed pulleys 33 and 34 is sleeved on the outer wall of the toothed pulleys 33 and 34.
[0029] Motor 32 is a servo motor and has a self-locking function.
[0030] A hollow cylinder 37 is fixedly connected to the front side of the toothed pulley 34. A motor 38 is fixedly connected inside the hollow cylinder 37. The output shaft of the motor 38 passes through the front outer wall of the hollow cylinder 37 and is fixedly connected to a worm 39. Two symmetrical L-shaped fixing rods 310 are fixedly connected to the front side of the hollow cylinder 37. A sector worm wheel 311 is rotatably connected to the bend of each of the two L-shaped fixing rods 310. Both sector worm wheels 311 are meshed with the worm 39.
[0031] Rotating rod 312 is fixedly connected to the outer wall of the left and right fan-shaped worm gears 311 on the side away from the worm 39. The ends of the left and right rotating rods 312 that are far apart from each other are rotatably connected to bent rods 313. The front ends of the left and right L-shaped fixed rods 310 are rotatably connected to rotating rods 314. The ends of the left and right rotating rods 314 that are far apart from each other are rotatably connected to the left and right bent rods 313 respectively. Pressure sensors 315 are fixedly connected to the opposite surfaces of the left and right bent rods 313. Anti-slip rubber pads 316 are fixedly connected to the opposite surfaces of the left and right pressure sensors 315.
[0032] Motor 2 38 is a servo motor. Pressure sensor 315 is electrically connected to motor 2 38. L-shaped fixed rod 310, rotating rod 1 312, bending rod 313, and rotating rod 2 314 form a parallelogram structure.
[0033] In some examples, the rotary clamping assembly 3 is also located on the top of the stage 11, used for flexible clamping of the automotive gasket while adjusting its angle, thereby achieving optimal observation angle positioning of the gasket edge and cross-sectional tissue. The rotary shaft 30 is rotatably connected to the rear side of the top of the stage 11, and an L-shaped rotary plate 31 is fixedly connected to its outer wall. A motor 32 is fixedly connected to the upper rear side wall of the L-shaped rotary plate 31. The motor 32 is a servo motor with a self-locking function, such as a Panasonic Minas A5 series servo motor. Model A5BE0421A000 has an output shaft that passes through the front side wall of an L-shaped rotating plate 31 and is fixedly connected to a toothed pulley 33. The bottom of the front side wall of the L-shaped rotating plate 31 is rotatably connected to a rotating column 36 via a bearing. The front end of the rotating column 36 is fixedly connected to a toothed pulley 34. The outer walls of the toothed pulleys 33 and 34 are fitted with a synchronous toothed belt 35. The synchronous toothed belt 35 meshes with the toothed pulleys 33 and 34, so that the rotating column 36 can be driven to rotate when the motor 32 drives it.
[0034] In some examples, motor 38 is also a servo motor, such as the Mitsubishi MR-JE series servo motor model MR-JE-10A. Its output shaft passes through the front outer wall of the hollow cylinder 37 and is fixedly connected to a worm gear 39. Two symmetrical L-shaped fixed rods 310 are fixedly connected to the front of the hollow cylinder 37. A sector worm wheel 311 is rotatably connected to the bend of each of the two L-shaped fixed rods 310. The sector worm wheel 311 meshes with the worm gear 39, so that when motor 38 drives the worm gear 39 to rotate, it can drive the sector worm wheel 311 to swing. A rotating rod 312 is fixedly connected to the outer wall of each of the two sector worm wheels 311 on the side away from the worm gear 39. A bent rod 313 is rotatably connected to the ends of the two rotating rods 312 that are away from each other. The front end is rotatably connected to a rotating rod 314 via a pin. The two rotating rods 314 are rotatably connected to two bent rods 313 on the left and right sides respectively. The L-shaped fixed rod 310, rotating rod 312, bent rod 313 and rotating rod 314 form a parallelogram structure to ensure smooth clamping movement. Pressure sensors 315 are fixedly connected to the opposite surfaces of the two bent rods 313. The pressure sensors 315 can be TEConnectivity MS5837 pressure sensors to detect clamping force. The pressure sensors 315 are electrically connected to motor 38, and flexible clamping is achieved through feedback control. Anti-slip rubber pads 316 are fixedly connected to the opposite surfaces of the two pressure sensors 315 to increase clamping friction and protect the surface of the pads.
[0035] When microscopic observation of the edge or cross-section of an automotive gasket at a specific angle is required, the rotating clamping assembly 3 is used. First, motor 2 38 is started, driving the worm gear 39 to rotate. The worm gear 39 drives the two meshing sector worm wheels 311 to swing towards or away from each other. The swinging of the sector worm wheels 311 drives the rotating rod 1 312 on them to move. Through the parallelogram structure composed of the L-shaped fixed rod 310, rotating rod 1 312, bent rod 313, and rotating rod 2 314, the swinging of the sector worm wheels 311 is converted into the parallel opening and closing motion of the two bent rods 313. As the two bent rods 313 move towards each other, the fixed rod... The anti-slip rubber pads 316 on the pad contact and clamp the car gasket from both sides. During this process, the pressure sensor 315 monitors the clamping force on the gasket in real time and feeds the signal back to the second motor 38. When the clamping force reaches the preset safety value, the system controls the second motor 38 to stop operating, achieving flexible clamping and avoiding damage to the precision gasket sample due to excessive clamping force. After the gasket is stably clamped, the first motor 32 is started. The output shaft of the first motor 32 drives the toothed pulley 33 to rotate. The toothed pulley 33 transmits power to the second toothed pulley 34 through the synchronous toothed belt 35, thereby driving the rotating column 36 to rotate. Due to the hollow cylinder The entire clamping structure, including the L-shaped fixing rod 310, the sector worm gear 311, and the bending rod 313, is fixedly connected to the toothed pulley 34. Therefore, the entire clamping mechanism will rotate as a whole around the rotating column 36. The motor 32, as a servo motor with a self-locking function, can be precisely controlled and locked at any angle. This allows the operator to adjust the edge or cross-section of the automotive gasket to the optimal observation angle so that the objective lens 12 and eyepiece 13 can observe its microstructure most clearly. When the rotating clamping assembly 3 is not needed, the L-shaped rotating plate 31 can be manually rotated to make it rotate the clamping components. To avoid affecting the use of the gasket plane fixing component 2, in this embodiment, the rotating clamping component 3 can precisely rotate and fix the gasket at any observation angle. This allows the operator to no longer be limited to observing the flat surface of the gasket, but to specifically align and observe the edges (such as burrs, wear) and cross-sections (such as coating thickness, internal grain flow direction, and heat treatment effect) of the gasket. By adjusting to the optimal angle, the microstructure of these key parts can be revealed more clearly, and unprecedented three-dimensional structural information can be obtained, which is crucial for analyzing the sealing performance, fatigue strength, and process integrity of the gasket.
[0036] The working principle and usage of this utility model are as follows: When routine microscopic observation of the planar structure of an automotive gasket is required, the operator places the automotive gasket sample flat on the top of the stage 11, directly above the light aperture 20. At this time, the light emitted by the illumination lamp 10 passes through the light aperture 20 and evenly illuminates the surface of the gasket sample. The elastic specimen clips 22 located on both sides of the light aperture 20 use their own elastic deformation force to press and fix the automotive gasket on the stage 11 from both sides, preventing it from moving during observation. After the light passes through the sample, it is captured by the objective lens 12. The image is captured, magnified, and finally formed for the operator to observe through eyepiece 13. This mode is suitable for rapid and stable detection of features such as the planar crystal phase and porosity of the gasket. In this embodiment, with the gasket planar fixing component 2, when the gasket needs to be observed in a conventional planar manner, the operator only needs to place the gasket at the designated position on the stage, and the elastic specimen clamp can instantly press and fix it. This "place and fix" method eliminates the tedious screw tightening or adjustment steps, greatly shortens the clamping time of a single sample, and is very suitable for scenarios on the production line that require rapid and batch testing.
[0037] When microscopic observation of the edge or cross-section of an automotive gasket at a specific angle is required, the rotating clamping assembly 3 is used. First, motor 2 38 is started, driving the worm gear 39 to rotate. The worm gear 39 drives the two meshing sector worm wheels 311 to swing towards or away from each other. The swinging of the sector worm wheels 311 drives the rotating rod 1 312 on them to move. Through the parallelogram structure composed of the L-shaped fixed rod 310, rotating rod 1 312, bent rod 313, and rotating rod 2 314, the swinging of the sector worm wheels 311 is converted into the parallel opening and closing motion of the two bent rods 313. As the two bent rods 313 move towards each other, the fixed rod... The anti-slip rubber pads 316 on the pad contact and clamp the car gasket from both sides. During this process, the pressure sensor 315 monitors the clamping force on the gasket in real time and feeds the signal back to the second motor 38. When the clamping force reaches the preset safety value, the system controls the second motor 38 to stop operating, achieving flexible clamping and avoiding damage to the precision gasket sample due to excessive clamping force. After the gasket is stably clamped, the first motor 32 is started. The output shaft of the first motor 32 drives the toothed pulley 33 to rotate. The toothed pulley 33 transmits power to the second toothed pulley 34 through the synchronous toothed belt 35, thereby driving the rotating column 36 to rotate. Due to the hollow cylinder The entire clamping structure, including the L-shaped fixing rod 310, the sector worm gear 311, and the bending rod 313, is fixedly connected to the toothed pulley 34. Therefore, the entire clamping mechanism will rotate as a whole around the rotating column 36. The motor 32, as a servo motor with a self-locking function, can be precisely controlled and locked at any angle. This allows the operator to adjust the edge or cross-section of the automotive gasket to the optimal observation angle so that the objective lens 12 and eyepiece 13 can observe its microstructure most clearly. When the rotating clamping assembly 3 is not needed, the L-shaped rotating plate 31 can be manually rotated to drive the clamping components to rotate. To avoid affecting the use of the gasket plane fixing component 2, in this embodiment, the gasket can be precisely rotated and fixed at any observation angle by the set rotation clamping component 3. This allows the operator to no longer be limited to observing the flat surface of the gasket, but to specifically align and observe the edges (such as burrs, wear) and cross-sections (such as coating thickness, internal grain flow direction, heat treatment effect) of the gasket. By adjusting to the optimal angle, the microstructure of these key parts can be revealed more clearly, and unprecedented three-dimensional structural information can be obtained, which is crucial for analyzing the sealing performance, fatigue strength and process integrity of the gasket.
