Description

Technical Field

[0001] This utility model relates to the field of automotive gasket manufacturing technology, specifically to an automotive gasket surface roughness detection device. Background Technology

[0002] In the automotive manufacturing industry, surface roughness is a key quality indicator affecting the sealing performance, friction characteristics, and service life of automotive gaskets. Accurate detection of this parameter is crucial for ensuring product reliability. Existing automotive gasket surface roughness testing technologies mainly fall into two categories: contact and non-contact. Contact testing, represented by stylus profilometers, uses a diamond stylus to scan the surface and record displacement changes, accurately obtaining core parameters such as Ra and Rz. Non-contact testing encompasses optical interferometry, laser scanning, and other methods, utilizing photoelectric conversion principles to achieve non-destructive measurement and adapting to gaskets with various surface characteristics. These technologies are widely used in the quality control stages of automotive parts production, providing reliable data support for optimizing gasket processing techniques.

[0003] In existing technologies, the lack of a clamp spacing adjustment component means the device can only be fixed for shims within a specific diameter range. If different sized shims need to be inspected, the machine must be stopped and the matching special clamps manually replaced, failing to meet the demands of modern manufacturing for multi-variety, flexible production. Furthermore, the lack of a clamping and flipping component means the inspection process must be completely interrupted after inspecting the first side. Operators must manually loosen the clamps, remove the shim, flip it by feel, then put it back into the clamps, roughly align it, and finally re-clamp it. This process is time-consuming and labor-intensive, resulting in extremely low inspection efficiency and failing to meet the pace requirements of modern production. Additionally, existing technologies can only inspect a single fixed position on the shim. To inspect other points, operators must manually loosen the clamps and move the shim, a crude and imprecise method that cannot achieve precise point control, leading to incomplete and unreliable inspection data. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an automotive gasket surface roughness detection device, which solves the technical problems of existing technology that can only be used for gaskets with a specific diameter range. Once gaskets of different sizes need to be detected, the machine must be stopped and the matching special fixture must be manually replaced. After the first side is detected, the detection process must be completely interrupted and the gasket must be flipped over, resulting in low work efficiency. The device can only detect a fixed position on the gasket and cannot achieve precise point control.

[0005] According to one aspect, at least one embodiment of the present invention provides an automotive gasket surface roughness detection device, comprising: A base, the top of which is fixedly connected to a controller; A clamp spacing adjustment assembly is provided at the top center of the base. The clamp spacing adjustment assembly is used to adjust the distance between the left and right clamps to accommodate automotive gaskets of different diameters. The flip clamping assembly consists of two components, with the left and right flip clamping assemblies respectively positioned on opposite sides of the clamp spacing adjustment assembly. The flip clamping assembly is used to clamp and fix the automotive gasket, and can also flip the clamped automotive gasket. A positioning component is disposed on the upper surface of the base. The positioning component is used to adjust the height of the roughness tester and to adjust the position of the clamped automotive gasket in the left and right directions.

[0006] For example, in at least one embodiment of the present invention, an automotive gasket surface roughness testing device is provided, wherein the clamp spacing adjustment assembly includes a fixed frame, a rotating shaft is rotatably connected to the inner bottom wall of the fixed frame, a gear is fixedly connected to the top of the rotating shaft, and racks symmetrical about its center are meshed on both the front and rear sides of the gear. A left-right oriented slide rail is fixedly connected to the inner bottom wall of the fixed frame, and two left-right symmetrical moving blocks are slidably connected to the outer wall of the slide rail. A cylinder is fixedly connected to the right side of the fixed frame, and the telescopic end of the cylinder penetrates into the interior of the fixed frame and is fixedly connected to the right moving block.

[0007] For example, in a vehicle gasket surface roughness detection device provided in at least one embodiment of the present invention, the right-side moving block is fixedly connected to the rear rack, the left-side moving block is fixedly connected to the front rack, the top of both the left and right moving blocks is fixedly connected to a side plate, the bottom of the fixing frame is fixedly connected to a slider, and the controller is electrically connected to the cylinder.

[0008] For example, in at least one embodiment of the present invention, an automotive gasket surface roughness detection device includes a flip-clamping assembly comprising a motor, which is fixedly connected to a side plate via a motor mounting bracket. The output shaft of the motor extends through the side plate to the side near the automotive gasket and is fixedly connected to a flip plate. A second motor is fixedly connected to the top of the flip plate, and the output shaft of the second motor extends through the bottom of the flip plate and is fixedly connected to a rotating rod. Connecting rods are rotatably connected to both ends of the rotating rod. A cross slide rail is fixedly connected to the side of the flip plate away from the side plate. Cross sliders that slide slidably with the outer wall of the cross slide rail are rotatably connected to the sides of the two connecting rods that are far from each other. Clamping blocks are fixedly connected to the sides of the two cross sliders that are close to the automotive gasket.

[0009] For example, in a car gasket surface roughness detection device provided in at least one embodiment of the present invention, rubber protective pads are fixedly connected to the sides of the two clamping blocks that are close to each other, and the controller is electrically connected to motor one and motor two respectively.

[0010] For example, in a vehicle gasket surface roughness detection device provided in at least one embodiment of the present invention, the positioning component includes a rectangular groove, which is opened on the top of the base and runs in a left-right direction. A lead screw is rotatably connected inside the rectangular groove. A motor is fixedly connected to the left side of the base. The output shaft of the motor passes through the inside of the rectangular groove and is fixedly connected to the lead screw. The outer wall of the lead screw is threadedly connected to a slider, and the outer wall of the slider is slidably connected to the inner wall of the rectangular groove.

[0011] For example, in at least one embodiment of the present invention, a surface roughness testing device for automotive gaskets is provided, wherein a fixed frame is fixedly connected to the top rear side of the base, an electric telescopic rod is fixedly connected to the top of the fixed frame, two left-right symmetrical slide rails are fixedly connected to the front side of the fixed frame, the telescopic end of the electric telescopic rod passes through the inner top wall of the slide rails and is fixedly connected to a lifting block that is slidably connected to the outer wall of the two slide rails, and a roughness tester is fixedly connected to the front side of the lifting block.

[0012] For example, in at least one embodiment of the present invention, an automotive gasket surface roughness detection device is provided, wherein the controller is electrically connected to a motor, an electric telescopic rod, and a roughness detector.

[0013] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the adjustable clamp spacing component allows a single testing device to quickly adapt to and clamp automotive gaskets of different diameters. Whether the gasket is small or large, switching can be completed simply by adjusting the spacing via the controller. This avoids the need to design and manufacture a customized testing fixture for each gasket specification, greatly improving the equipment's versatility and reducing equipment investment costs for users facing multi-variety, small-batch production. The flip-clamping component allows the operator to clamp the gasket only once, and the device automatically flips it to present the front and back surfaces of the gasket to the roughness tester above. This eliminates the tedious steps of manually removing, flipping, re-clamping, and aligning the gasket after the initial test, improving equipment efficiency. The positioning component allows the roughness tester to make precise adjustments in height and lateral directions. This enables the probe of the roughness tester to accurately contact and measure any specific point on the gasket, such as the working sealing surface or edge areas, ensuring that the collected data accurately and comprehensively reflects the surface quality of the entire gasket and avoiding misjudgments caused by a single testing point.

[0023] like Figure 1 As shown, it illustrates a device for detecting the surface roughness of automotive gaskets according to an embodiment of the present invention, comprising: Base 1, with controller 10 fixedly connected to the top of base 1; The clamp spacing adjustment component 2 is located at the top center of the base 1. The clamp spacing adjustment component 2 is used to adjust the distance between the left and right clamps in order to accommodate automotive gaskets of different diameters. The flip clamping assembly 3 consists of two components, with the left and right flip clamping assemblies 3 respectively positioned on opposite sides of the clamp spacing adjustment assembly 2. The flip clamping assembly 3 is used to clamp and fix the automotive gasket, and can also flip the clamped automotive gasket. Positioning component 4 is disposed on the upper surface of base 1. Positioning component 4 is used to adjust the height of the roughness tester and adjust the position of the clamped automotive gasket in the left and right directions.

[0024] In some embodiments, the base 1 is a rectangular platform made of aluminum alloy, which provides stable support. A controller 10 is fixedly connected to the top of the base 1. The controller 10 is a Siemens S7-1200 PLC programmable logic controller, which is used to coordinate the operation of the entire device. The controller 10 is connected to various electrical components through cables to realize electrical control.

[0025] like Figure 2 As shown, this invention illustrates a clamp spacing adjustment assembly 2 in another embodiment of the present invention. The clamp spacing adjustment assembly 2 includes a fixed frame 20. A rotating shaft 21 is rotatably connected to the inner bottom wall of the fixed frame 20. A gear 22 is fixedly connected to the top of the rotating shaft 21. A rack 23 symmetrical about its center is meshed on both the front and rear sides of the gear 22. A left-right oriented slide rail 27 is fixedly connected to the inner bottom wall of the fixed frame 20. Two left-right symmetrical moving blocks 25 are slidably connected to the outer wall of the slide rail 27. A cylinder 24 is fixedly connected to the right side of the fixed frame 20. The telescopic end of the cylinder 24 extends into the interior of the fixed frame 20 and is fixedly connected to the right moving block 25.

[0026] The right moving block 25 is fixedly connected to the rear rack 23, the left moving block 25 is fixedly connected to the front rack 23, the top of both left and right moving blocks 25 is fixedly connected to the side plate 26, the bottom of the fixed frame 20 is fixedly connected to the slider 28, and the controller 10 is electrically connected to the cylinder 24.

[0027] In some examples, the clamp spacing adjustment component 2 is located at the top center of the base 1 to adjust the spacing between the two flip clamping components 3. The fixing frame 20 is fixed to the base 1 by bolts, and a rotating shaft 21 is rotatably connected to its inner bottom wall. A gear 22 is fixedly connected to the top of the rotating shaft 21. Racks 23 are meshed on both the front and rear sides of the gear 22. The two racks 23 are symmetrically arranged about the center of the gear 22. A left-right sliding rail 27 is fixedly connected to the inner bottom wall of the fixing frame 20. Two left-right symmetrical moving blocks 25 are slidably connected to the outer wall of the sliding rail 27. A cylinder 24 is fixedly connected to the right side of the fixing frame 20. The cylinder 24 is a double-acting cylinder of the SMCCXS series. Its telescopic end extends into the interior of the fixing frame 20 and is fixedly connected to the right moving block 25. When the cylinder 24 extends or retracts, it pushes... The right moving block 25 slides along the slide rail 27 and is fixedly connected to the rear rack 23. The left moving block 25 is fixedly connected to the front rack 23. Therefore, the action of the cylinder 24 is transmitted to the rack 23 through the moving block 25, so that the two racks 23 move synchronously towards or away from each other, thereby driving the gear 22 to rotate. The rotation of the gear 22 further coordinates the movement of the rack 23, ensuring that the two moving blocks 25 move synchronously. The top of both the left and right moving blocks 25 is fixedly connected to the side plate 26, which is used to install the flipping clamping assembly 3. The bottom of the fixed frame 20 is fixedly connected to the slider 28, which cooperates with the positioning assembly 4 to realize the overall left and right movement. The controller 10 is electrically connected to the cylinder 24. The controller 10 can programmably control the extension and retraction of the cylinder 24 to precisely adjust the clamping distance.

[0028] During operation, the operator first places the car gasket to be inspected between the two left and right flipping clamping components 3, roughly in the center position. The controller 10 issues a command to activate the cylinder 24 in the clamp spacing adjustment component 2. The extension or retraction rod of the cylinder 24 pushes the right-side moving block 25 to slide along the slide rail 27. The right-side moving block 25 drives the rear rack 23 to move. Through the transmission of the gear 22 meshing with it, the front rack 23 is forced to move in the opposite direction synchronously, thereby driving the left-side moving block 25 to move synchronously towards or away from each other. The movement of the two moving blocks 25 drives the top side plate 26 and the entire assembly mounted on it. The flip-grip assembly 3 moves together until the movement trajectories of the two pairs of gripping blocks 37 are aligned with the edge of the automotive gasket. At this point, the spacing adjustment is complete to accommodate gaskets of different diameters. In this embodiment, the clamp spacing adjustment assembly 2 enables a single detection device to quickly adapt to and clamp automotive gaskets of different diameters. Whether it is a small gasket or a large gasket, the switching can be completed simply by adjusting the spacing through the controller. This avoids the need to design and manufacture a customized detection fixture for each type of gasket, greatly improving the versatility of the equipment and reducing the equipment investment cost for users when facing multi-variety, small-batch production.

[0029] like Figures 3-4 As shown, this invention illustrates a flip-grip assembly 3 in another embodiment. The flip-grip assembly 3 includes a motor 30, which is fixedly connected to a side plate 26 via a motor mounting bracket. The output shaft of the motor 30 extends through the side plate 26 near the car gasket and is fixedly connected to a flip plate 31. A motor 32 is fixedly connected to the top of the flip plate 31. The output shaft of the motor 32 extends through the bottom of the flip plate 31 and is fixedly connected to a rotating rod 33. Connecting rods 34 are rotatably connected to both ends of the rotating rod 33. A cross slide rail 36 is fixedly connected to the side of the flip plate 31 away from the side plate 26. Cross sliders 35 that slide on the outer wall of the cross slide rail 36 are rotatably connected to the sides of the two connecting rods 34 that are far from each other. Clamping blocks 37 are fixedly connected to the sides of the two cross sliders 35 near the car gasket.

[0030] Rubber protective pads are fixedly connected to the sides of the two clamping blocks 37 that are close to each other. The controller 10 is electrically connected to motor 1 30 and motor 2 32 respectively.

[0031] In some examples, there are two flip-grip assemblies 3, mounted on the left and right side plates 26 respectively. Motor 1 30 is a Panasonic A6 series servo motor, fixedly connected to the side plate 26 via a motor mounting bracket. The output shaft of motor 1 30 passes through the side plate 26 near the automotive gasket and is fixedly connected to a flip plate 31. When motor 1 30 operates, it drives the flip plate 31 to rotate, thereby flipping the entire gripping mechanism. Motor 2 32, also a Panasonic A6 series servo motor, is fixedly connected to the top of the flip plate 31. The output shaft of motor 2 32 passes through the bottom of the flip plate 31 and is fixedly connected to a rotating rod 33. Connecting rods 34 are rotatably connected to both ends of the rotating rod 33. A cross slide rail 36 is fixedly connected to the side of the flip plate 31 away from the side plate 26. Two connecting rods 34 are rotatably connected to cross sliders 35 on opposite sides. The cross sliders 35 are slidably connected to the outer wall of the cross slide rail 36. Clamping blocks 37 are fixedly connected to the sides of the front and rear cross sliders 35 near the car gasket. Rubber protective pads are fixedly connected to the clamping surfaces of the clamping blocks 37 to prevent scratching the surface of the car gasket. When the second motor 32 is running, it drives the rotating rod 33 to rotate, which pushes the cross sliders 35 to slide along the cross slide rail 36 through the connecting rod 34, causing the front and rear clamping blocks 37 to move towards or away from each other, thereby clamping or releasing the car gasket. The controller 10 is electrically connected to the first motor 30 and the second motor 32 respectively. The controller 10 can control the clamping force and the flip angle. For example, during testing, the first motor 30 can drive the gasket to flip 180 degrees to test the other side of the surface.

[0032] When it is necessary to clamp, fix, and flip the car gasket, under the control of the controller 10, the two motors 32 on the flipping clamping assembly 3 start simultaneously. The motor 32 drives the rotating rod 33 to rotate, and the rotating rod 33 pushes the two connecting rods 34, causing the cross sliders 35 at the ends of the connecting rods 34 to slide along the cross slide rail 36 towards the center of the gasket. The two cross sliders 35 drive the clamping blocks 37 on them to move closer synchronously, firmly clamping the car gasket from both front and rear directions. The rubber protective pads on the clamping blocks 37 prevent scratching the surface of the gasket. When it is necessary to inspect the other side of the gasket, the controller 10 starts the motor 30, and the motor 30 drives the flipping plate 31 and... The entire clamping mechanism mounted on it includes a motor 32, a rotating rod 33, a clamping block 37, and the clamped automotive gasket, which rotate together. It can typically rotate 180 degrees. This flipping action will make the gasket surface that was originally facing forward face backward, or change its angle, so that the roughness tester 47 can perform the test. In this embodiment, with the setting of the flipping clamping component 3, the operator only needs to perform one clamping operation. The device can automatically present the front and back surfaces of the gasket to the roughness tester above through the flipping action. This eliminates the series of tedious steps that need to be manually removed, flipped, re-clamped, and aligned after the first test, thus improving the working efficiency of the equipment.

[0033] like Figure 5 As shown, the positioning component 4 in another embodiment of the present invention is illustrated. The positioning component 4 includes a rectangular groove 40, which is opened on the top of the base 1 and runs in a left-right direction. A lead screw 41 is rotatably connected inside the rectangular groove 40. A motor 42 is fixedly connected to the left side of the base 1. The output shaft of the motor 42 passes through the interior of the rectangular groove 40 and is fixedly connected to the lead screw 41. The outer wall of the lead screw 41 is threadedly connected to the slider 28, and the outer wall of the slider 28 is slidably connected to the inner wall of the rectangular groove 40.

[0034] A fixed frame 43 is fixedly connected to the top rear side of the base 1. An electric telescopic rod 44 is fixedly connected to the top of the fixed frame 43. Two left-right symmetrical slide rails 45 are fixedly connected to the front side of the fixed frame 43. The telescopic end of the electric telescopic rod 44 passes through the inner top wall of the slide rail 45 and is fixedly connected to a lifting block 46 that slides and connects to the outer wall of the two slide rails 45. A roughness detector 47 is fixedly connected to the front side of the lifting block 46.

[0035] The controller 10 is electrically connected to the motor 42, the electric telescopic rod 44, and the roughness tester 47.

[0036] In some examples, the positioning component 4 is set on the upper surface of the base 1 to adjust the height and left and right position of the roughness tester 47. The rectangular groove 40 is opened on the top of the base 1 and runs left and right. The inside of the rectangular groove 40 is rotatably connected to the lead screw 41. The left side of the base 1 is fixedly connected to the motor 3 42. The motor 3 42 is a Panasonic A6 series servo motor. Its output shaft passes through the inside of the rectangular groove 40 and is fixedly connected to the lead screw 41. The outer wall of the lead screw 41 is threadedly connected to the slider 28 of the clamping distance adjustment component 2. The outer wall of the slider 28 is slidably connected to the inner wall of the rectangular groove 40. When the motor 3 42 runs, it drives the lead screw 41 to rotate, causing the slider 28 to move left and right along the rectangular groove 40, thereby driving the entire clamping distance adjustment component 2 and the flip clamping component 3 to move left and right, realizing the left and right position adjustment of the automotive gasket.

[0037] In some examples, a fixed frame 43 is fixedly connected to the top rear side of the base 1, and an electric telescopic rod 44 is fixedly connected to the top of the fixed frame 43. The electric telescopic rod 44 is a LINAKLA36 series electric push rod. Two symmetrical slide rails 45 are fixedly connected to the front side of the fixed frame 43. The telescopic end of the electric telescopic rod 44 extends through the inner top wall of the slide rails 45 and is fixedly connected to a lifting block 46. The lifting block 46 is slidably connected to the outer wall of the two slide rails 45. A roughness detector 47 is fixedly connected to the front side of the lifting block 46. The roughness detector 47 is a roughness detector... Using the Mitutoyo SJ-410 series surface roughness measuring instrument, when the electric telescopic rod 44 extends or retracts, it drives the lifting block 46 to move up and down along the slide rail 45, thereby adjusting the height of the roughness measuring instrument 47 so that it contacts the surface of the pad. The controller 10 is electrically connected to the motor 42, the electric telescopic rod 44 and the roughness measuring instrument 47 respectively. Through the controller 10, the left and right position and height of the roughness measuring instrument 47 can be programmably controlled to ensure the accuracy of the detection point. The roughness measuring instrument 47 feeds back the measurement data to the controller 10 for recording or display.

[0038] When positioning is required, controller 10 activates motor 3 42 in positioning assembly 4. Motor 3 42 drives lead screw 41 to rotate. Slider 28, threadedly connected to lead screw 41, moves the entire clamping spacing adjustment assembly 2 and the clamped automotive gasket left and right along rectangular groove 40, moving the area of ​​the gasket to be inspected to the vicinity of roughness tester 47. Then, controller 10 activates electric telescopic rod 44. The telescopic end of electric telescopic rod 44 pushes lifting block 46 downward, causing it to descend smoothly along slide rail 2 45 until the probe of roughness tester 47 makes slight contact with the surface of the automotive gasket to be measured and reaches the preset measurement pressure. Roughness tester 47 is then triggered and begins to scan and measure the roughness of the gasket surface. The measurement data is transmitted in real time. The data is transmitted to the controller 10 or the host computer for recording and processing. After all tests are completed, the electric telescopic rod 44 lifts the roughness tester 47 away from the gasket surface, the motor 32 rotates in the opposite direction, driving the clamping block 37 to release the car gasket, and the cylinder 24 actuates to return the clamp to the initial spacing. The operator can then remove the tested car gasket. In this embodiment, the positioning component 4 allows the roughness tester to be precisely adjusted in height and left and right directions. This allows the probe of the roughness tester 47 to accurately contact and measure any specific point on the gasket, such as the working sealing surface, edge area, etc., ensuring that the collected data can truly and comprehensively reflect the surface quality of the entire gasket and avoid misjudgment caused by a single test point.

[0039] The working principle and usage process of this utility model are as follows: During operation, the operator first places the car gasket to be tested between the two left and right flipping clamping components 3, approximately in the center position. The controller 10 issues a command to activate the cylinder 24 in the clamp spacing adjustment component 2. The extension or retraction rod of the cylinder 24 pushes the right-side moving block 25 to slide along the slide rail 27. The right-side moving block 25 drives the rear rack 23 to move. Through the transmission of the gear 22 meshing with it, the front rack 23 is forced to move in the opposite direction synchronously, thereby driving the left-side moving block 25 to move synchronously towards or away from each other. The movement of the two moving blocks 25 on the left and right sides drives the top side plate 26 to... The entire flip-grip assembly 3 mounted on it moves together until the movement trajectories of the two pairs of clamping blocks 37 are aligned with the edge of the automotive gasket. At this point, the spacing adjustment is complete to accommodate gaskets of different diameters. In this embodiment, the clamp spacing adjustment assembly 2 enables a single detection device to quickly adapt to and clamp automotive gaskets of different diameters. Whether it is a small gasket or a large gasket, the switching can be completed simply by adjusting the spacing through the controller. This avoids the need to design and manufacture a customized detection fixture for each type of gasket, greatly improving the versatility of the equipment and reducing the equipment investment cost for users when facing multi-variety, small-batch production.

[0040] When it is necessary to clamp, fix, and flip the car gasket, under the control of the controller 10, the two motors 32 on the flipping clamping assembly 3 start simultaneously. The motor 32 drives the rotating rod 33 to rotate, and the rotating rod 33 pushes the two connecting rods 34, causing the cross sliders 35 at the ends of the connecting rods 34 to slide along the cross slide rail 36 towards the center of the gasket. The two cross sliders 35 drive the clamping blocks 37 on them to move closer synchronously, firmly clamping the car gasket from both front and rear directions. The rubber protective pads on the clamping blocks 37 prevent scratching the surface of the gasket. When it is necessary to inspect the other side of the gasket, the controller 10 starts the motor 30, and the motor 30 drives the flipping plate 31 and... The entire clamping mechanism mounted on it includes a motor 32, a rotating rod 33, a clamping block 37, and the clamped automotive gasket, which rotate together. It can typically rotate 180 degrees. This flipping action will make the gasket surface that was originally facing forward face backward, or change its angle, so that the roughness tester 47 can perform the test. In this embodiment, with the setting of the flipping clamping component 3, the operator only needs to perform one clamping operation. The device can automatically present the front and back surfaces of the gasket to the roughness tester above through the flipping action. This eliminates the series of tedious steps that need to be manually removed, flipped, re-clamped, and aligned after the first test, thus improving the working efficiency of the equipment.

[0041] When positioning is required, controller 10 activates motor 3 42 in positioning assembly 4. Motor 3 42 drives lead screw 41 to rotate. Slider 28, threadedly connected to lead screw 41, moves the entire clamping spacing adjustment assembly 2 and the clamped automotive gasket left and right along rectangular groove 40, moving the area of ​​the gasket to be inspected to the vicinity of roughness tester 47. Then, controller 10 activates electric telescopic rod 44. The telescopic end of electric telescopic rod 44 pushes lifting block 46 downward, causing it to descend smoothly along slide rail 2 45 until the probe of roughness tester 47 makes slight contact with the surface of the automotive gasket to be measured and reaches the preset measurement pressure. Roughness tester 47 is then triggered and begins to scan and measure the roughness of the gasket surface. The measurement data is transmitted in real time. The data is transmitted to the controller 10 or the host computer for recording and processing. After all tests are completed, the electric telescopic rod 44 lifts the roughness tester 47 away from the gasket surface, the motor 32 rotates in the opposite direction, driving the clamping block 37 to release the car gasket, and the cylinder 24 actuates to return the clamp to the initial spacing. The operator can then remove the tested car gasket. In this embodiment, the positioning component 4 allows the roughness tester to be precisely adjusted in height and left and right directions. This allows the probe of the roughness tester 47 to accurately contact and measure any specific point on the gasket, such as the working sealing surface, edge area, etc., ensuring that the collected data can truly and comprehensively reflect the surface quality of the entire gasket and avoid misjudgment caused by a single test point.
