Description
Technical Field
[0001] This utility model belongs to the field of precision optical surface inspection technology, specifically an automatic adjustment platform and a universal connection device for various inspection fixtures. Background Technology
[0002] The UA3P coordinate measuring machine is an ultra-high precision 3D measuring device launched by Panasonic, designed for fields such as optics, automotive, and consumer electronics, enabling nanometer-level precision inspection. Its core technology employs a three-way laser interferometry method to locate the XYZ axis coordinates with 0.3 nanometer resolution. Combined with a miniature air slider and laser focusing system, it ensures a constant measurement force of 0.15-0.30 mN, avoiding contact deformation. The device supports 70-degree tilt measurement with an accuracy of ±0.10 μm, covering a measurement range from 30 mm to 500 mm, and can inspect complex components such as aspherical lenses and freeform surface molds. The latest UA3P-4000C model integrates a non-contact camera unit and a 7-axis robot, achieving automated pick-and-place and edge detection, improving efficiency by 4 times. On the software side, the PIZA system supports Zernike analysis, eccentricity assessment, and data meshing processing, and is compatible with CAD model import and NC path planning, meeting the needs of the entire precision manufacturing process. It is widely used in nanometer-level quality control of smartphone periscopes, automotive HUDs, and VR optical components.
[0003] The UA3P platform has a fixed structure, and when changing fixtures, the fixture must be manually "sinked" into the platform's groove. This process requires operators to maintain extremely high concentration during alignment; even slight carelessness can result in collisions with the platform's precision guide rails, probes, or sensors, with a single repair cost exceeding 200,000 yuan. Each fixture change requires 2-3 minutes of focused operation (including cleaning, alignment, and placement of the test object for calibration). Prolonged periods of high concentration can easily lead to operator fatigue, and fixtures are changed at least 30 times per day.
[0004] Under current technological conditions, different test products require fixtures with custom-made bases, which not only leads to redundant inventory but also results in extremely low changeover efficiency.
[0005] Therefore, this utility model provides an automatic adjustment platform that is universally compatible with various testing fixtures. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The utility model provides a universal connecting device for an automatic adjustment platform and various testing fixtures, including a connecting plate; the top of the connecting plate has multiple mounting holes, the middle of the connecting plate has a first positioning groove, the middle of the first positioning groove has a second positioning groove, and one side of the first and second positioning grooves is connected to a placement groove. The placement groove is formed on the surface of the first and second positioning grooves, and the middle of the second positioning groove has a through hole communicating with the second positioning groove. A fixing component is provided on one side of the through hole. During operation, the connecting plate is placed on the automatic adjustment platform and fixed through the mounting holes. Any surface-type testing fixture is pushed into the placement groove. The fixture is placed on the connecting plate so that it fits into the first or second positioning groove. It is then reinforced by the fixing component. The detection device on the automatic adjustment platform is then activated to detect the fixture. After the detection is completed, the fixture on the connecting plate is replaced. The previous fixture is removed, and the new fixture is placed on the connecting plate. After operating the fixing component, the fixture is pushed to fit into the first or second positioning groove. By setting the connecting plate, mounting holes, first positioning groove, second positioning groove, placement groove, and through hole, the installation and replacement of fixtures are facilitated. This can effectively reduce the probe wear rate on the automatic adjustment platform by 75%, realize the rapid switching of various detection fixtures, reduce the difficulty of operation, and thus improve the detection efficiency.
[0008] Preferably, the fixing component includes a bracket provided on one side of the through hole. The bracket is fixedly connected to the placement groove. A screw is threadedly connected to the middle of the bracket, and a push block is fixedly connected to one end of the screw. During operation, after the fixture is placed on the connecting plate, the screw is rotated to push the push block closer to the fixture. The push block then pushes the fixture to fit more closely to the edge of the first or second positioning groove. The push block cooperates with the first or second positioning groove to achieve a stable effect on the fixture, reducing the possibility of the fixture shaking during testing, which could lead to errors in the fixture's testing results, or the fixture colliding with the probe of the automatic adjustment platform and damaging the probe. By setting the bracket, screw, and push block, the fixture placed on the connecting plate is further reinforced, reducing the possibility of the fixture shaking during testing.
[0009] Preferably, the first and second positioning grooves have two movable grooves in their middle sections. A movable plate is slidably connected to the middle of each movable groove. A slider is fixedly connected to one end of the movable plate. A spring is fixedly connected to the bottom of the slider. A fixed plate is fixedly connected to the bottom of the spring. The fixed plate is fixedly connected to a connecting plate. A sleeve is provided on the outside of the spring. The sleeve is fixedly connected to the fixed plate. The movable plate, slider, and sleeve are slidably connected. A groove is formed in the middle of the fixed plate. A rope is slidably connected to the middle of the groove. The rope is slidably connected to the connecting plate. One end of the rope is fixedly connected to the slider, and the other end of the rope is fixedly connected to the push block. During operation, the movable plate... Initially, the fixture is positioned above the connecting plate. When the fixture is placed on the connecting plate, it first contacts the movable plate. The push block, driven by the screw, moves closer to the fixture, simultaneously causing the rope to slide. The rope pulls the slider within the slider, and the movable plate slides down within the movable groove, allowing the fixture to be placed into the first or second positioning groove. During this process, the rope continuously pulls the slider, keeping the spring compressed. After the test is completed, when changing the fixture, the screw is first rotated to release the push block's grip on the fixture. As the push block moves, it causes the rope to slide, reducing the tension on the slider. The spring rebounds, pushing the slider and movable plate upwards, causing the fixture to pop out for easy removal and replacement. This speeds up fixture replacement efficiency.
[0010] Preferably, the movable plate is provided with multiple balls on both sides, the balls are rotatably connected to the sleeve, and the balls are in corresponding contact with the movable plate. During operation, the balls increase the lubrication between the movable plate and the sleeve, reducing the situation of jamming caused by excessive friction.
[0011] Preferably, a sponge block is provided on one side of the ball bearing. The sponge block is fixedly connected to the sleeve and is in corresponding contact with the movable plate. During operation, when the movable plate slides in and out of the slot of the sleeve, the sponge block wipes the movable plate. At the same time, the sponge block can fill the gap between the movable plate and the sleeve, reducing the possibility of impurities entering the gap and increasing friction.
[0012] Preferably, two blocks are fixedly connected to the top of the movable plate. The blocks correspond to the first positioning groove and the second positioning groove, respectively. A protective pad is provided on one side of the block. The protective pad is fixedly connected to the movable plate. During operation, the blocks correspond to the positions of the first positioning groove and the second positioning groove. When the fixture is placed on the movable plate, the blocks limit the fixture to reduce the possibility of the fixture slipping or tilting. The protective pad protects the fixture.
[0013] The beneficial effects of this utility model are as follows: 1. The automatic adjustment platform and the universal connection device for various testing fixtures described in this utility model, by setting a connecting plate, mounting holes, a first positioning groove, a second positioning groove, a placement groove, and a through hole, facilitates the installation and replacement of fixtures, effectively reduces the probe wear rate on the automatic adjustment platform by 75%, realizes rapid switching of various testing fixtures, reduces the difficulty of operation, and thus improves the testing efficiency.
[0014] 2. The automatic adjustment platform and the universal connection device for various testing fixtures described in this utility model further reinforces the fixtures placed on the connection plate by setting up brackets, screws and push blocks, thereby reducing the shaking of the fixtures during the testing process.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1 to 2As shown in the embodiment of this utility model, a universal connection device for an automatic adjustment platform and various testing fixtures includes a connecting plate 1. The top of the connecting plate 1 has multiple mounting holes 11. A first positioning groove 12 is formed in the middle of the connecting plate 1. A second positioning groove 13 is formed in the middle of the first positioning groove 12. A placement groove 14 is connected to one side of the first positioning groove 12 and the second positioning groove 13. The placement groove 14 is formed on the surface of the first positioning groove 12 and the second positioning groove 13. A through hole 15 is formed in the middle of the second positioning groove 13, communicating with the second positioning groove 13. A fixing component is provided on one side of the through hole 15. During operation, the connecting plate 1 is placed on the automatic adjustment platform and fixed through the mounting holes 11. Any surface-shaped testing fixture is pushed into the placement groove 14 and placed... On the connecting plate 1, the fixture is made to fit with the first positioning groove 12 or the second positioning groove 13. It is reinforced by the fixing component and the first positioning groove 12 or the second positioning groove 13. Then, the detection device on the automatic adjustment platform is started to detect the fixture. After the detection is completed, the fixture on the connecting plate 1 is replaced. After the previous fixture is removed, the new fixture is placed on the connecting plate 1. After operating the fixing component, the fixture is pushed to fit with the first positioning groove 12 or the second positioning groove 13. By setting the connecting plate 1, the mounting hole 11, the first positioning groove 12, the second positioning groove 13, the placement groove 14, and the through hole 15, the installation and replacement of the fixture are convenient. It can effectively reduce the probe wear rate on the automatic adjustment platform by 75%, realize the rapid switching of multiple detection fixtures, reduce the operation difficulty, and thus improve the detection efficiency.
[0019] like Figures 1 to 3 As shown, the fixing assembly includes a bracket 2 provided on one side of the through hole 15. The bracket 2 is fixedly connected to the placement groove 14. A screw 21 is threadedly connected to the middle of the bracket 2. A push block 22 is fixedly connected to one end of the screw 21. During operation, after the fixture is placed on the connecting plate 1, the screw 21 is rotated to push the push block 22 closer to the fixture. The push block 22 then pushes the fixture to fit more closely to the edge of the first positioning groove 12 or the second positioning groove 13. The push block 22 cooperates with the first positioning groove 12 or the second positioning groove 13 to achieve a stable effect on the fixture, reducing the possibility of the fixture shaking during testing, which could lead to errors in the fixture testing results, or the fixture colliding with the probe of the automatic adjustment platform and causing damage to the probe. By setting the bracket 2, screw 21, and push block 22, the fixture placed on the connecting plate 1 is further reinforced, reducing the possibility of the fixture shaking during testing.
[0020] like Figures 1 to 4As shown, two movable grooves 3 are formed in the middle of the first positioning groove 12 and the second positioning groove 13. A movable plate 31 is slidably connected to the middle of the movable groove 3. A slider 32 is fixedly connected to one end of the movable plate 31. A spring 33 is fixedly connected to the bottom of the slider 32. A fixed plate 34 is fixedly connected to the bottom of the spring 33. The fixed plate 34 is fixedly connected to the connecting plate 1. A sleeve 35 is provided on the outside of the spring 33. The sleeve 35 is fixedly connected to the fixed plate 34. The movable plate 31, the slider 32 and the sleeve 35 are slidably connected. A groove 36 is formed in the middle of the fixed plate 34. A rope 37 is slidably connected to the middle of the groove 36. The rope 37 is slidably connected to the connecting plate 1. One end of the rope 37 is fixedly connected to the slider 32. The other end of the rope 37 is fixedly connected to the push block 22. During operation... Initially, the movable plate 31 is above the connecting plate 1. When the fixture is placed on the connecting plate 1, it first contacts the movable plate 31. The push block 22 moves closer to the fixture under the drive of the screw 21, while simultaneously driving the rope 37 to slide. The rope 37 pulls the slider 32 to slide within the slider 32, and the movable plate 31 slides down within the movable groove 3, allowing the fixture to be placed in the first positioning groove 12 or the second positioning groove 13. During this process, the rope 37 continuously pulls the slider 32, keeping the spring 33 compressed. After the test is completed, when changing the fixture, first rotate the screw 21 to loosen the push block 22's grip on the fixture. When the push block 22 moves, it drives the rope 37 to slide, reducing the tension on the slider 32. The spring 33 rebounds, pushing the slider 32 and the movable plate 31 upward, causing the fixture to pop out, making it easier to pick up and replace the fixture. This can speed up the fixture replacement efficiency.
[0021] like Figures 1 to 4 As shown, multiple balls 4 are provided on both sides of the movable plate 31. The balls 4 are rotatably connected to the sleeve 35. The balls 4 are in corresponding contact with the movable plate 31. During operation, the balls 4 increase the lubrication of the contact between the movable plate 31 and the sleeve 35, reducing the situation of jamming caused by excessive friction.
[0022] like Figures 1 to 4 As shown, a sponge block 5 is provided on one side of the ball bearing 4. The sponge block 5 is fixedly connected to the sleeve 35. The sponge block 5 is in corresponding contact with the movable plate 31. During operation, when the movable plate 31 slides in and out of the slot of the sleeve 35, the sponge block 5 wipes the movable plate 31. At the same time, the sponge block 5 can fill the gap between the movable plate 31 and the sleeve 35, reducing the situation where impurities enter the gap and increase the friction.
[0023] like Figures 1 to 5As shown, two blocks 6 are fixedly connected to the top of the movable plate 31. The blocks 6 correspond to the first positioning groove 12 and the second positioning groove 13 respectively. A protective pad 61 is provided on one side of the blocks 6. The protective pad 61 is fixedly connected to the movable plate 31. During operation, the blocks 6 correspond to the positions of the first positioning groove 12 and the second positioning groove 13. When the fixture is placed on the movable plate 31, the blocks 6 limit the fixture to reduce the possibility of the fixture slipping or tilting. The protective pad 61 protects the fixture.
[0024] Working principle: Place the connecting plate 1 on the automatic adjustment platform and install it through the mounting holes 11. Push any face shape detection fixture from the placement slot 14 onto the connecting plate 1, so that the fixture fits into the first positioning slot 12 or the second positioning slot 13. Reinforce it by using the fixing components to work with the first positioning slot 12 or the second positioning slot 13. Then, start the detection device on the automatic adjustment platform to detect the fixture. After the detection is completed, replace the fixture on the connecting plate 1. Remove the previous fixture and place the new fixture on the connecting plate 1. After operating the fixing components, push the fixture to fit into the first positioning slot 12 or the second positioning slot 13. This is achieved by setting the connecting plate 1, mounting holes 11, first positioning slot 12, second positioning slot 13, and placement slot 14. The slot 14 and through hole 15 facilitate fixture installation and replacement, effectively reducing probe wear rate on the automatic adjustment platform by 75%, enabling rapid switching between various testing fixtures, reducing operational difficulty, and thus improving testing efficiency. After the fixture is placed on the connecting plate 1, rotating the screw 21 pushes the push block 22 closer to the fixture. The push block 22 then pushes the fixture closer to the edge of the first positioning slot 12 or the second positioning slot 13. The push block 22 cooperates with the first positioning slot 12 or the second positioning slot 13 to achieve a stable fixture, reducing fixture shaking during testing, which could lead to errors in the fixture's testing results, or damage to the probes due to collisions between the fixture and the probes on the automatic adjustment platform. By setting the bracket 2, screw 21, and push block 22 to stabilize the fixture placed on the connecting plate 1, the fixture is effectively stabilized. The fixture on the connecting plate 1 is further reinforced to reduce wobbling during testing. The movable plate 31 is initially positioned above the connecting plate 1. When the fixture is placed on the connecting plate 1, it first contacts the movable plate 31. Driven by the screw 21, the push block 22 moves closer to the fixture, simultaneously causing the rope 37 to slide. The rope 37 pulls the slider 32, causing it to slide within the slider 32. The movable plate 31 slides down within the movable groove 3, allowing the fixture to be placed into the first positioning groove 12 or the second positioning groove 13. During this process, the rope 37 continuously pulls the slider 32, keeping the spring 33 compressed. After testing, when changing the fixture, the screw 21 is first rotated to release the push block 22's grip on the fixture. As the push block 22 moves, it causes the rope 37 to slide, reducing the pressure on the slider. The tension of 32 and the rebound of spring 33 push the slider 32 and movable plate 31 upward, causing the fixture to pop out, making it easier to pick up and replace the fixture. This can speed up the fixture replacement efficiency. The ball bearing 4 increases the lubrication of the contact between the movable plate 31 and the sleeve 35, reducing the situation of jamming caused by excessive friction. When the movable plate 31 slides in and out of the slot of the sleeve 35, the sponge block 5 wipes the movable plate 31. At the same time, the sponge block 5 can fill the gap between the movable plate 31 and the sleeve 35, reducing the situation of impurities entering the gap and increasing friction. The stop block 6 corresponds to the position of the first positioning groove 12 and the second positioning groove 13. When the fixture is placed on the movable plate 31, the stop block 6 limits the fixture and reduces the situation of the fixture slipping and tilting. The protective pad 61 protects the fixture.
