Description

Technical Field

[0001] This invention relates to the field of oil seal quality inspection technology, and in particular to an all-around dimensional laser inspection device for oil seal quality inspection. Background Technology

[0002] Oil seals (also known as sealing rings or oil seal rings) are critical components used to prevent the leakage of liquids or gases, and are widely used in various fields such as automobiles, machinery, and engineering. Quality inspection is a crucial step in the production and use of oil seals, and its main purpose is to ensure the performance, durability, and adaptability of the oil seals.

[0003] The prior art publication CN121346671A provides a device and method for measuring residual silicon thickness. This technology can effectively suppress background stray light, enhance the contrast of the internal copper pillar image, and make the processing module more accurate and reliable in determining the focus state, thereby improving measurement accuracy.

[0004] However, when inspecting oil seals using laser and video methods, the lack of separation between the workpiece and inspection equipment and the external environment in current technology allows airborne particles to scatter the laser beam, weakening the laser signal and affecting measurement accuracy. Simultaneously, dust and other particles can obstruct the camera's view, resulting in blurry images and impacting subsequent image processing and analysis. This leads to inaccurate focus determination, potentially causing inconsistencies and increased errors, ultimately reducing overall measurement precision.

[0005] In summary, the existing technology lacks a technique for spatial separation testing when inspecting the quality of oil seals. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing an all-around dimensional laser inspection device for oil seal quality inspection.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an all-around dimensional laser inspection device for oil seal quality inspection, comprising a video measuring instrument body, a laser scanner mounted on the video measuring instrument body, a fixed frame fixedly connected to the video measuring instrument body, an adjusting frame slidably fitted on the fixed frame, an adjusting mechanism slidably fitted on the adjusting frame, an isolation mechanism fixedly connected to one end of the adjusting frame, an exhaust seat fixedly connected to the isolation mechanism, and a transmission mechanism rotatably connected to the exhaust seat.

[0008] Preferably, a sealing plate is fixedly connected to the main body of the video measuring instrument, and a placement plate is provided below the sealing plate. The placement plate is rotatably connected to the main body of the video measuring instrument.

[0009] Preferably, a lead screw is rotatably connected to the inner wall of the fixed frame, a motor is fixedly connected to one end of the lead screw, the motor is fixedly connected to the inner wall of the fixed frame, and a trapezoidal block is fixedly connected to the fixed frame.

[0010] Preferably, the bottom center of the adjusting frame is rotatably connected to the lead screw, the outer wall of the bottom of the adjusting frame is slidably fitted to the inner wall of the fixed frame, and a guide rod is fixedly connected to one side of the top of the adjusting frame.

[0011] Preferably, the adjustment mechanism includes a sliding frame, with both ends of the sliding frame slidably engaged with the adjustment frame, the bottom end of the sliding frame slidably contacting the trapezoidal block, and two adjusting racks fixedly connected to the top end of the sliding frame in a symmetrical structure.

[0012] Preferably, an adjusting gear is engaged with one side of the adjusting rack, a universal joint is fixedly connected to the adjusting gear, the universal joint is rotatably connected to the adjusting frame, a push frame is fixedly connected to the other end of the universal joint, the two push frames are of different lengths, and a contact wheel is rotatably connected to the other end of the push frame.

[0013] Preferably, the isolation mechanism includes a fixed ring, which is fixedly connected to the adjusting frame. The fixed ring has two movable rings, a first movable ring and a second movable ring, slidably fitted at its upper and lower ends respectively. Each movable ring has a contact frame fixedly connected to the side of the second movable ring near the adjusting frame. The contact frame is slidably fitted through a guide rod. The two contact frames are slidably in contact with two contact wheels respectively. Multiple springs are fixedly connected in a ring structure between the first movable ring and the second movable ring. The top end of the first movable ring abuts against the bottom surface of the sealing plate, and the bottom end of the second movable ring abuts against the top surface of the placement plate. An air pump is fixedly connected through one side of the first movable ring. The fixed ring, the first movable ring, and the second movable ring are made of transparent material.

[0014] Preferably, the exhaust seat input end is fixedly connected to one side of the movable ring, and the exhaust seat output end is rotatably connected to a toothed ring, on which an L-shaped filter tube is fixedly connected by bolts.

[0015] Preferably, the transmission mechanism includes an impeller, which is rotatably connected to the inner wall of the exhaust seat. A worm is fixedly connected to the bottom end of the impeller, and a worm wheel is meshed and driven on one side of the worm. The worm wheel is rotatably connected to the outer wall of the exhaust seat via a pin, and a transmission gear is fixedly connected to one end of the worm wheel. The transmission gear meshes and drives with a gear ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting up an isolation mechanism in conjunction with a sealing plate and a placement plate, the oil seal and measurement structure can be separated from the outside world when the video measuring instrument and laser scanner measure the oil seal on the placement plate. This effectively isolates the external microparticles and dust, reduces the scattering of the laser signal during propagation, and improves the consistency of measurement results due to the reduction of environmental interference. This reduces the need for repeated testing, saves time and human resources, and can significantly improve the accuracy, efficiency, and stability of the video measuring instrument and laser scanner in oil seal quality inspection. By installing an exhaust seat and transmission mechanism on the isolation mechanism, after the isolation space is formed, the air pump injects filtered air from the outside into the isolation space to exhaust the air containing particulate matter inside, keeping the measurement environment clean, thereby improving the accuracy and reliability of laser and video detection. The air is filtered through the L-shaped filter tube on the exhaust seat. At the same time, when the high-pressure air passes through the exhaust seat, it drives the impeller, which in turn drives the L-shaped filter tube to rotate, ensuring its filtration efficiency. This makes the omnidirectional laser detection device for oil seal quality inspection help create a safer working environment during the exhaust and filtration process, reducing the health impact of airborne particulate matter on operators and ensuring the safety and comfort of the working environment. By installing a lead screw within the fixed frame, the isolation mechanism can move laterally, allowing users to quickly replace the oil seal under test, reducing replacement time and improving work efficiency. Simultaneously, as the lead screw drives the isolation mechanism to move laterally, the trapezoidal block, adjusting mechanism, and spring enable the automatic extension and retraction of movable rings one and two within the isolation mechanism, forming an isolation space. This reduces the need for manual intervention, especially in achieving the automatic extension and retraction of the movable rings, significantly reducing the time and effort required for manual adjustment. This greatly enhances the flexibility, accuracy, and efficiency of the omnidirectional laser inspection device for oil seal quality testing. Attached Figure Description

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-8 The illustrated omnidirectional dimensional laser inspection device for oil seal quality inspection includes a video measuring instrument body 1, a laser scanner 2 mounted on the video measuring instrument body 1, a fixed frame 3 fixedly connected to the video measuring instrument body 1, an adjusting frame 4 slidably mounted on the fixed frame 3, an adjusting mechanism 5 slidably mounted on the adjusting frame 4, an isolation mechanism 6 fixedly connected to one end of the adjusting frame 4, an exhaust seat 7 fixedly connected to the isolation mechanism 6, and a transmission mechanism 8 rotatably connected to the exhaust seat 7.

[0021] Among them, the laser scanner 2 uses a semiconductor laser source to adapt to the all-round size detection of oil seals of different specifications; the overall structure adopts a modular design and the components are firmly connected.

[0022] By setting up the isolation mechanism 6 in conjunction with the sealing plate 101 and the placement plate 102, the oil seal and the measuring structure can be separated from the outside world when the video measuring instrument body 1 and the laser scanner 2 measure the oil seal on the placement plate 102. This effectively isolates the external microparticles and dust, reduces the scattering of the laser signal during propagation, and improves the consistency of the measurement results due to the reduction of environmental interference. This reduces the need for repeated testing, saves time and human resources, and can significantly improve the accuracy, efficiency, and stability of the video measuring instrument body 1 and the laser scanner 2 in oil seal quality inspection.

[0023] like Figure 3 As shown, a sealing plate 101 is fixedly connected to the main body 1 of the video measuring instrument, and a placement plate 102 is provided below the sealing plate 101. The placement plate 102 is rotatably connected to the main body 1 of the video measuring instrument.

[0024] The sealing plate 101 is made of aluminum alloy with a polished bottom surface, and fits and seals with the movable ring 602. The placement plate 102 is a high-precision rotating platform made of stainless steel with a nitrided surface, which can drive the oil seal to rotate 360° to achieve all-round dimensional inspection.

[0025] like Figure 4 As shown, a lead screw 301 is rotatably connected to the inner wall of the fixed frame 3, and a motor 302 is fixedly connected to one end of the lead screw 301. The motor 302 is fixedly connected to the inner wall of the fixed frame 3, and a trapezoidal block 303 is fixedly connected to the fixed frame 3.

[0026] The fixed frame 3 is welded from high-strength steel, which is rigid and can effectively absorb operating vibrations to ensure smooth sliding of the adjustment frame 4; the motor 302 is a servo motor; the trapezoidal block 303 is made of alloy steel with a polished surface to ensure smooth triggering of the adjustment mechanism 5.

[0027] like Figure 4 As shown, the bottom center of the adjusting frame 4 is rotatably connected to the lead screw 301, the outer wall of the bottom of the adjusting frame 4 is slidably fitted to the inner wall of the fixed frame 3, and a guide rod 401 is fixedly connected to one side of the top of the adjusting frame 4.

[0028] The adjustment frame 4 is made of aluminum alloy, which is lightweight and strong, and slides smoothly without deviation from the inner wall of the fixed frame 3; the guide rod 401 is made of stainless steel and plays a precise guiding role for the contact frame 604.

[0029] like Figure 5As shown, the adjustment mechanism 5 includes a sliding frame 501. Both ends of the sliding frame 501 are slidably engaged with the adjustment frame 4, and the bottom end of the sliding frame 501 is in slidable contact with the trapezoidal block 303. Two adjusting racks 502 are fixedly connected to the top of the sliding frame 501 in a symmetrical structure. The sliding frame 501 is made of engineering plastic and slides flexibly.

[0030] An adjusting gear 503 is provided on one side of the adjusting rack 502 for meshing transmission. A universal joint 504 is fixedly connected to the adjusting gear 503. The universal joint 504 is rotatably connected to the adjusting frame 4. A push frame 505 is fixedly connected to the other end of the universal joint 504. The two push frames 505 have different lengths. A contact wheel 506 is rotatably connected to the other end of the push frame 505.

[0031] The contact wheel 506 is made of polyurethane with a smooth surface. It slides in contact with the contact frame 604 without jamming or wear. The contact wheel 506 has high rotational precision, ensuring uniform pushing force.

[0032] like Figure 6 As shown, the isolation mechanism 6 includes a fixed ring 601, which is fixedly connected to the adjusting frame 4. The fixed ring 601 has two movable rings 602 and 603 slidably fitted at its upper and lower ends, respectively. Contact frames 604 are fixedly connected to the side of each movable ring 602 and 603 near the adjusting frame 4. The contact frames 604 are slidably fitted through the guide rod 401. The two contact frames 604 are slidably in contact with two contact wheels 506. Multiple springs 605 are fixedly connected in a ring structure between the movable rings 602 and 603. The top of the movable ring 602 abuts against the bottom surface of the sealing plate 101, and the bottom of the movable ring 603 abuts against the top surface of the placement plate 102. An air pump 606 is fixedly connected through one side of the movable ring 602. The fixed ring 601, movable ring 602, and movable ring 603 are made of transparent material.

[0033] The fixed ring 601, movable ring 1 602, and movable ring 2 603 are made of high-transmittance acrylic material, which is impact-resistant and not easily scratched. The inner wall is treated with anti-static material to prevent dust adsorption. The ends of movable ring 1 602 and movable ring 2 603 are equipped with rubber sealing gaskets to fit and seal with the sealing plate 101 and the placement plate 102. The spring 605 is a stainless steel compression spring, which can drive movable ring 1 602 and movable ring 2 603 to reset. The air pump 606 is a high-pressure air pump, and the exhaust inlet is equipped with a high-efficiency filter to ensure that the air injected into the isolation space is clean.

[0034] like Figure 7 As shown, the input end of the exhaust seat 7 is fixedly connected to one side of the movable ring 603, and the output end of the exhaust seat 7 is rotatably connected to a toothed ring 701. An L-shaped filter tube 702 is fixedly connected to the toothed ring 701 by bolts.

[0035] The exhaust seat 7 is made of aluminum alloy, and the L-shaped filter tube 702 can be quickly disassembled and replaced with bolts, making maintenance convenient.

[0036] like Figure 8 As shown, the transmission mechanism 8 includes an impeller 801, which is rotatably connected to the inner wall of the exhaust seat 7. A worm 802 is fixedly connected to the bottom end of the impeller 801. A worm wheel 803 is meshed and driven on one side of the worm 802. The worm wheel 803 is rotatably connected to the outer wall of the exhaust seat 7 via a pin. A transmission gear 804 is fixedly connected to one end of the worm wheel 803. The transmission gear 804 meshes and drives the ring gear 701.

[0037] The impeller 801 is made of aluminum alloy and the blades have an arc-shaped structure. It can rotate at high speed under the drive of high-pressure air. The worm 802 and worm wheel 803 are made of alloy steel and can drive the toothed ring 701 and L-shaped filter tube 702 to rotate, so that the filter surface of the L-shaped filter tube 702 is evenly stressed, avoiding local blockage and ensuring stable filtration efficiency.

[0038] Working principle: The oil seal to be tested is placed on the placement plate 102. Then, the motor 302 is started by the controller to rotate, driving the adjusting frame 4 to move the isolation mechanism 6 towards the testing area. When the bottom end of the sliding frame 501 slides along the inclined surface of the trapezoidal block 303, the inclined surface thrust of the trapezoidal block 303 drives one side of the sliding frame 501 to move, thereby driving the two sets of adjusting racks 502 at the top to move synchronously. The adjusting racks 502 mesh with the adjusting gears 503, driving the two adjusting gears 503 to rotate, through the universal joint... The joint 504, pusher 505, and contact wheel 506 push the contact frame 604 to slide along the guide rod 401; the contact frame 604 drives the first movable ring 602 to extend upward and the second movable ring 603 to extend downward, and the spring 605 is stretched until the rubber pad at the top of the first movable ring 602 is in contact with the bottom surface of the sealing plate 101 and the rubber pad at the bottom of the second movable ring 603 is in contact with the top surface of the placement plate 102, forming a closed isolation space; the motor 302 stops running, the adjusting frame 4 locks in position, and the automatic sealing is completed.

[0039] Start the air pump 606. The air pump 606 filters the outside air through the high-efficiency filter at the air inlet and injects it into the isolation space, creating a slight positive pressure in the isolation space. The high-pressure air pushes the air containing particulate matter in the isolation space to be discharged through the exhaust seat 7. When the air flows through the exhaust seat 7, it drives the impeller 801 to rotate at high speed. The impeller 801 drives the worm gear 802 to rotate. Through the meshing of the worm gear 803, the transmission gear 804 and the gear ring 701, the L-shaped filter tube 702 is driven to rotate, intercepting residual particulate matter and discharging clean air to the workshop.

[0040] The video measuring instrument body 1 and laser scanner 2 are activated. The laser scanner 2 emits a laser signal to detect the dimensions of the oil seal. The placement plate 102 drives the oil seal to rotate slowly 360°, realizing the detection of the inner and outer diameters, thickness, concentricity, and other dimensions of the oil seal. The video measuring instrument body 1 simultaneously acquires images of the oil seal, which complements the laser measurement data to improve the detection accuracy. During the detection process, the isolation space is kept clean to avoid dust particles interfering with the laser signal, ensuring the accuracy of the measurement data. The detection results are transmitted to the controller in real time for automatic recording and analysis.

[0041] After a single oil seal is tested, the air pump 606 stops working, the motor 302 drives the adjusting frame 4 to move away from the testing area, the sliding frame 501 moves along the inclined surface of the trapezoidal block 303, the adjusting mechanism 5 resets, the spring 605 contracts, and the movable ring 1 602 and movable ring 2 603 return to their positions, thus releasing the isolation space; the tested oil seal is taken out, the next oil seal to be tested is placed in, and the above steps are repeated to achieve batch continuous testing.
