Description

Technical Field

[0001] This invention belongs to the field of SLA coating equipment testing technology, specifically relating to an SLA scraper surface levelness testing device and a pre-testing method for scraper levelness. Background Technology

[0002] During the sliding operation of the SLA scraper on the double-sided guide rails, the bottom surface is required to coincide with the horizontal plane. Therefore, when both ends of the scraper are mounted on the slider and the middle section is suspended in the air, the flatness of the bottom surface must reach .mm.

[0003] Currently, after the scraper is finished, the bottom of the scraper is placed directly on a level marble surface, and then a level is placed on top of the scraper to confirm that the top surface is also level. This confirms that when the top of the scraper is level, the bottom is also level.

[0004] The problem with this method of confirming levelness during installation is that when both ends of the scraper are fixed and the middle section is suspended, gravity can cause the middle section to dip, leading to a problem with the flatness of the scraper's bottom surface. After the scraper is installed on the equipment, it becomes impossible to detect the levelness of the scraper's bottom surface. Therefore, it is necessary to simulate the scraper's installation environment for testing and confirmation before installation.

[0005] Therefore, there is a need for an SLA scraper surface levelness detection device and a pre-detection method for scraper levelness to solve the problem in the existing technology that when using a level instrument, the levelness of the scraper surface can only be detected, but the bottom level cannot be detected. Summary of the Invention

[0006] The purpose of this invention is to provide an SLA scraper surface levelness detection device and a method for pre-detecting scraper levelness, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an SLA scraper surface levelness detection device, comprising a marble detection platform, guide rails fixed on both sides of the top surface of the marble detection platform, a slider movably engaged on the guide rails, a mounting plate fixed on the top surface of the slider, a placement block fixed on the top surface of the mounting plate, a first connecting ball fixed on the top surface of the placement block, a first fitting post movably connected to the first connecting ball, a first connecting rod fixed at one end of the first fitting post, a second connecting rod provided on one side of the first connecting rod, a tightening knob movably connected between the first connecting rod and the second connecting rod on opposite sides, a second fitting post fixed at one end of the second connecting rod, a second connecting ball movably connected inside the second fitting post, a connecting post fixed on the outer wall of the second connecting ball, a rotating component provided on one side of the connecting post, a dial indicator provided on the rotating component, and a pointer provided on the dial indicator.

[0008] Furthermore, the rotating assembly includes a guide post, which is fixed to one end of the connecting post. A fixing clip is fixed to one side of the outer wall of the guide post. A second tightening knob is movably connected between the inner sidewalls of the fixing clip and the sidewalls of the fixing clip that are close to each other. A third connecting ball is movably connected inside the fixing clip. A third connecting rod is fixed to the outer wall of the third connecting ball. The dial indicator is fixed to one end of the third connecting rod.

[0009] Furthermore, two leveling blocks are fixed on one side of the top surface of the marble inspection platform, and an SLA scraper body is arranged between the top surfaces of the two leveling blocks. A level is placed on the top surface of the SLA scraper body.

[0010] Furthermore, a top groove is formed on the top surface of the contour block, and an inner groove is formed on the bottom surface of the inner side wall of the top groove. Two locking blocks are movably engaged in the inner groove, and a limit post is fixed on the top surface of the locking blocks. Two locking holes are respectively formed on opposite sides of the outer side wall of the SLA scraper body.

[0011] Furthermore, the two equal-height blocks each have a first side opening at the top position of one side close to each other, and a limiting block is fixed on one side of the engaging block, the limiting block passing through the first side opening.

[0012] Furthermore, a rotating rod is movably connected inside the limiting block, and a connecting block is movably connected to one end of the two rotating rods. A fixing rod is fixed to the bottom surface of the connecting block, and a triangular frame is fixed to the bottom surface of the fixing rod.

[0013] Furthermore, two first positioning posts are fixed to one side of each of the two equal height blocks, and a stop bar is fixed to one end of each of the two first positioning posts. A T-shaped strip is movably connected to the outer wall of the two adjacent first positioning posts. A push bar is fixed to the top of the T-shaped strip near the side of the corresponding equal height block, and one end of the push bar is set at a chamfer.

[0014] Furthermore, a second side opening is provided at the bottom of one side of the T-shaped strip. Two equal-height blocks are respectively fixed with engaging toothed plates at the bottom of one side, which pass through the second side opening. Two second positioning posts are fixed on the top surface of the inner wall of the second side opening. The outer walls of the two second positioning posts are movably connected with mating teeth, which engage with the engaging toothed plates. A Z-shaped rod is fixed on one side of the mating teeth. A spring is provided on the outer wall of the second positioning post. The top end of the spring is fixed to the top surface of the inner wall of the second side opening, and the bottom end of the spring is fixed to the top surface of the mating teeth.

[0015] Furthermore, T-shaped grooves are respectively provided on the middle part of one side of the two equal height blocks close to each other, and a T-shaped block is fixed on the side of the triangular frame close to the corresponding equal height block, and the T-shaped block is movably engaged in the T-shaped groove.

[0016] This invention proposes a method for pre-detecting the levelness of an SLA scraper, which includes the following steps:

[0017] S1. Manually pull the two Z-shaped rods. The Z-shaped rods move upward, causing the mating teeth to move upward. At this time, the spring is compressed, and the mating teeth separate from the locking tooth plate. Then push the T-shaped bar. The movement of the T-shaped bar causes the push bar to move. The movement of the push bar pushes the triangular frame to move upward. The movement of the triangular frame causes the connecting block to move upward. The movement of the connecting block pushes the limit blocks on both sides to move away from each other until the distance between the two limit posts is at a suitable distance.

[0018] S2. Release the constraint on the Z-shaped rod, and the spring pushes the mating teeth so that the mating teeth engage with the locking tooth plate. At this time, the distance between the two limiting posts is fixed. Then, the four locking holes of the SLA scraper body are engaged with the four limiting posts. Then, the SLA scraper body is lowered. At this time, the SLA scraper body is between the top surfaces of the two equal height blocks, completing the positioning of the SLA scraper body.

[0019] S3. Place the level at the center of the top surface of the SLA scraper body, and then start the level. The level will detect the levelness of the SLA scraper body surface. When the levelness value of the top surface of the SLA scraper body is within 0.03mm, the top surface of the SLA scraper body is in a level state.

[0020] S4. Adjust the positions of the sliders on both sides so that they are in the corresponding positions on the SLA scraper body. Then, by rotating the first engagement post, guide post, first tightening knob, and second tightening knob on both sides respectively, make the two pointers correspond to the bottom plane of the SLA scraper body. Then, push the sliders on both sides to move the pointers and observe the changes in the dial indicator readings. When the change in the dial indicator readings on both sides is within 0.03mm, it indicates that the bottom surface of the SLA scraper body is in a horizontal state. When the measured values ​​on both the top and bottom surfaces of the SLA scraper body are within 0.03mm, it indicates that the SLA scraper body is in a horizontal state.

[0021] Compared with the prior art, the SLA scraper surface levelness detection device and the pre-detection method for scraper levelness provided by the present invention have at least the following beneficial effects:

[0022] (1) The level of the SLA scraper body surface can be detected by the level instrument. The position of the slider can be limited by the guide rail. The SLA scraper body can be supported by the level block, which facilitates the detection of the level of the SLA scraper body. The position of the dial indicator pointer can be adjusted by the cooperation of the first connecting ball, the first fitting column, the first connecting rod, the first tightening knob, the second connecting rod, the second fitting column, the second connecting ball, the guide column, the fixing clamp and the second tightening knob, so that the pointer is at the bottom of the SLA scraper body. This allows the top and bottom surfaces of the SLA scraper body to be detected separately. The SLA scraper body can be pre-tested after processing, avoiding the situation where the middle of the SLA scraper body is dented after installation, which would affect the normal use of the SLA scraper body.

[0023] (2) By setting the locking hole and limiting post, the horizontal position of the SLA scraper body can be limited, so that when the SLA scraper body is placed on the surface of two equal height blocks, the SLA scraper body is always in the middle position of the two equal height blocks, thereby effectively reducing the adjustment range of the rotating components on both sides, making it easier to quickly adjust the rotating components on both sides, and improving the adjustment efficiency of the pointer.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Research has found that existing technologies, when using a level gauge, can only detect the levelness of the scraper surface and cannot detect the levelness of the bottom. Therefore, Embodiment 1 proposes an SLA scraper surface levelness detection device, such as... Figures 1-8As shown, the SLA scraper surface levelness detection device includes a marble detection platform 100. Guide rails 101 are fixed to both sides of the top surface of the marble detection platform 100. A slider 200 is movably engaged on the guide rails 101. A mounting plate 201 is fixed to the top surface of the slider 200. A placement block 202 is fixed to the top surface of the mounting plate 201. A first connecting ball 203 is fixed to the top surface of the placement block 202. A first fitting post 204 is movably connected to the first connecting ball 203. A first connecting rod 205 is fixed to one end of the first fitting post 204. A second connecting rod 207 is provided on one side of the first connecting rod 205. A tightening knob is movably connected between the first connecting rod 205 and the second connecting rod 207 on one side close to each other. A second fitting post 300 is fixed to one end of the second connecting rod 207. A second connecting ball 301 is movably connected inside the second fitting post 300. A connecting post 302 is fixed to the outer wall of the second connecting ball 301. A rotating assembly is provided on one side of the connecting post 302. A dial indicator 308 is provided on the rotating assembly. A pointer 309 is provided on the dial indicator 308.

[0043] As a further embodiment of the present invention, the rotating assembly includes a guide post 303, which is fixed to one end of the connecting post 302. A fixing clip 304 is fixed to one side of the outer wall of the guide post 303. A second tightening knob 305 is movably connected between the inner sidewalls of the fixing clip 304 that are close to each other. A third connecting ball 306 is movably connected inside the fixing clip 304. A third connecting rod 307 is fixed to the outer sidewall of the third connecting ball 306. The dial indicator 308 is fixed to one end of the third connecting rod 307.

[0044] The fixed clip 304 and the second tightening knob 305 are configured to fix the position of the third connecting ball 306, thereby facilitating the fixation of the dial indicator 308.

[0045] As a further embodiment of the present invention, two leveling blocks 102 are fixed on one side of the top surface of the marble inspection platform 100, and an SLA scraper body 103 is provided between the top surfaces of the two leveling blocks 102. A level 400 is placed on the top surface of the SLA scraper body 103.

[0046] By setting the contour block 102, the position of the SLA scraper body 103 can be placed, which facilitates the inspection of the SLA scraper body 103.

[0047] As a further embodiment of the present invention, the top surface of the contour block 102 is provided with a top groove 500, the bottom surface of the inner side wall of the top groove 500 is provided with an inner groove 501, two locking blocks 503 are movably engaged in the inner groove 501, the top surface of the locking blocks 503 is fixed with a limit post 502, and two locking holes 104 are respectively provided on opposite sides of the outer side wall of the SLA scraper body 103.

[0048] By using the locking block 503 and the inner groove 501, the position of the limiting post 502 can be movably limited, thus facilitating the movement of the limiting post 502.

[0049] As a further embodiment of the present invention, the two equal height blocks 102 are respectively provided with a first side opening 504 at the top position of one side close to each other, and a limiting block 505 is fixed on one side of the engaging block 503, and the limiting block 505 passes through the first side opening 504.

[0050] The first side opening 504 allows the limiting block 505 to pass through it.

[0051] This solution includes the following working process: When positioning the SLA scraper body 103, the two Z-shaped rods 708 are manually pulled. The Z-shaped rods 708 move upward, causing the mating teeth 707 to move upward. At this time, the spring 706 is compressed, and the mating teeth 707 separate from the engaging tooth plate 709. Then, the T-shaped bar 700 is pushed. The movement of the T-shaped bar 700 causes the pusher bar 701 to move. The movement of the pusher bar 701 pushes the triangular frame 603 upward. The upward movement of the triangular frame 603 causes the connecting block 601 to move upward. The upward movement of the connecting block 601 pushes the limit blocks 505 on both sides. Move the two limit posts 502 away from each other until the distance between them is appropriate. Then release the constraint on the Z-shaped rod 708. The spring 706 pushes the mating tooth 707 so that the mating tooth 707 engages with the engaging tooth plate 709. At this time, the distance between the two limit posts 502 is fixed. Then, the four engaging holes 104 of the SLA scraper body 103 are engaged with the four limit posts 502. Then, the SLA scraper body 103 is moved down. At this time, the SLA scraper body 103 is between the top surfaces of the two equal height blocks 102, completing the positioning of the SLA scraper body 103. When the distance between the two limiting posts 502 is reduced, pull up the Z-shaped rod 708 to separate the mating teeth 707 from the engaging tooth plate 709. Then push the two limiting posts 502 closer together. Then release the Z-shaped rod 708 to engage the mating teeth 707 with the engaging tooth plate 709. This completes the reduction of the distance between the two limiting posts 502.

[0052] When testing the levelness of the top surface of the SLA scraper body 103, first place the level 400 at the center of the top surface of the SLA scraper body 103, then start the level 400. The level 400 tests the levelness of the surface of the SLA scraper body 103. When the levelness value of the top surface of the SLA scraper body 103 is within 0.03mm, the top surface of the SLA scraper body 103 is considered to be level.

[0053] When testing the levelness of the two sides of the bottom surface of the SLA scraper body 103, first adjust the positions of the sliders 200 on both sides so that the sliders 200 are in the corresponding positions of the SLA scraper body 103. Then, by rotating the first engagement post 204, guide post 303, first tightening knob 206, and second tightening knob 305 on both sides respectively, make the two pointers 309 correspond to the bottom surface of the SLA scraper body 103. Then, push the sliders 200 on both sides to move the pointers 309 and observe the change in the value of the dial indicator 308. When the change in the value of the dial indicator 308 on both sides is within 0.03mm, it indicates that the bottom surface of the SLA scraper body 103 is in a level state. When the measured values ​​of both the top and bottom surfaces of the SLA scraper body 103 are within 0.03mm, it indicates that the SLA scraper body 103 is in a level state.

[0054] According to the above working process: the level 400 allows the levelness of the SLA scraper body 103 surface to be detected; the guide rail 101 limits the position of the slider 200; the leveling block 102 supports the SLA scraper body 103, thus facilitating the detection of the levelness of the SLA scraper body 103; and the first connecting ball 203, first locking post 204, first connecting rod 205, first tightening knob 206, second connecting rod 207, and second locking post 3... The cooperation of the second connecting ball 301, guide post 303, fixing clamp 304, and second tightening knob 305 allows the position of the pointer 309 of the dial indicator 308 to be adjusted, so that the pointer 309 is positioned on the bottom surface of the SLA scraper body 103. This allows for the separate inspection of the top and bottom surfaces of the SLA scraper body 103, enabling pre-inspection of the SLA scraper body 103 after processing. This avoids the situation where the middle of the SLA scraper body 103 is dented after installation, which would affect the normal use of the SLA scraper body 103.

[0055] By using the locking hole 104 and the limiting post 502, the horizontal position of the SLA scraper body 103 can be limited, so that when the SLA scraper body 103 is placed on the surface of the two equal height blocks 102, the SLA scraper body 103 is always in the middle position of the two equal height blocks 102, thereby effectively reducing the adjustment range of the rotating components on both sides, facilitating the rapid adjustment of the rotating components on both sides, and improving the adjustment efficiency of the pointer 309.

[0056] As a further embodiment of the present invention, a rotating rod 600 is movably connected inside the limiting block 505, and a connecting block 601 is movably connected to one end of the two rotating rods 600. A fixing rod 602 is fixed to the bottom surface of the connecting block 601, and a triangular frame 603 is fixed to the bottom surface of the fixing rod 602.

[0057] The rotating rod 600 and connecting block 601 allow the limiting blocks 505 on both sides to move closer or further apart, thereby causing the two limiting posts 502 to move closer or further apart. The triangular frame 603 allows the pushing bar 701 to push the triangular frame 603, which in turn moves the triangular frame 603 upward.

[0058] As a further embodiment of the present invention, two first positioning posts 702 are fixed to one side of the two equal height blocks 102 respectively. A stop bar 703 is fixed to one end of the two first positioning posts 702. A T-shaped strip 700 is movably connected to the outer wall of the two adjacent first positioning posts 702. A push bar 701 is fixed to the top of the T-shaped strip 700 near the side of the corresponding equal height block 102. One end of the push bar 701 is set at a chamfer.

[0059] The first positioning post 702 is set so that the position of the T-shaped strip 700 can be movably limited. The pusher 701 is set so that when the pusher 701 moves, it can push the triangular frame 603 upward, thereby causing the two limiting posts 502 to move away from each other, so as to position the SLA scraper body 103 of different widths.

[0060] As a further embodiment of the present invention, a second side opening 704 is provided at the bottom of one side of the T-shaped strip 700. Two equal-height blocks 102 are respectively fixed with engaging tooth plates 709 at the bottom of one side close to each other. The engaging tooth plates 709 pass through the second side opening 704. Two second positioning posts 705 are fixed on the top surface of the inner side wall of the second side opening 704. The outer side walls of the two second positioning posts 705 are movably connected with mating teeth 707. The mating teeth 707 engage with the engaging tooth plates 709. A Z-shaped rod 708 is fixed on one side of the mating teeth 707. A spring 706 is provided on the outer side wall of the second positioning posts 705. The top end of the spring 706 is fixed to the top surface of the inner side wall of the second side opening 704, and the bottom end of the spring 706 is fixed to the top surface of the mating teeth 707.

[0061] The mating teeth 707 and spring 706 are designed to engage with the engaging tooth plate 709, thereby fixing the position of the T-shaped strip 700.

[0062] As a further embodiment of the present invention, the two equal height blocks 102 are provided with T-shaped grooves 604 on the middle part of one side of each other, and the triangular frame 603 is fixed with a T-shaped block 605 near the side of the corresponding equal height block 102, and the T-shaped block 605 is movably engaged in the T-shaped groove 604.

[0063] The T-slot 604 and T-block 605 are designed to allow the position of the triangular frame 603 to be flexibly restricted.

[0064] Example 2:

[0065] Based on Example 1, further research revealed that the steps might be unclear without further explanation. Therefore, Example 2 proposes a pre-detection method for the levelness of an SLA scraper, which includes the following steps:

[0066] S1. By manually pulling the two Z-shaped rods 708, the Z-shaped rods 708 move upward, causing the mating teeth 707 to move upward. At this time, the spring 706 is compressed, and the mating teeth 707 separate from the engaging tooth plate 709. Then, push the T-shaped bar 700. The movement of the T-shaped bar 700 causes the push bar 701 to move. The movement of the push bar 701 pushes the triangular frame 603 to move upward. The movement of the triangular frame 603 causes the connecting block 601 to move upward. The movement of the connecting block 601 pushes the limit blocks 505 on both sides to move away from each other until the distance between the two limit posts 502 is at a suitable distance.

[0067] S2. Release the constraint on the Z-shaped rod 708. The spring 706 pushes the mating tooth 707, so that the mating tooth 707 engages with the engaging tooth plate 709. At this time, the distance between the two limiting posts 502 is fixed. Then, the four engaging holes 104 of the SLA scraper body 103 are engaged with the four limiting posts 502. Then, the SLA scraper body 103 is moved down. At this time, the SLA scraper body 103 is between the top surfaces of the two equal height blocks 102, completing the positioning of the SLA scraper body 103.

[0068] S3. Place the level 400 at the center of the top surface of the SLA scraper body 103, and then start the level 400. The level 400 will detect the levelness of the surface of the SLA scraper body 103. When the levelness value of the top surface of the SLA scraper body 103 is within 0.03mm, the top surface of the SLA scraper body 103 is in a level state.

[0069] S4. Adjust the positions of the sliders 200 on both sides so that they are in the corresponding positions on the SLA scraper body 103. Then, by rotating the first engagement post 204, guide post 303, first tightening knob 206, and second tightening knob 305 on both sides respectively, make the two pointers 309 correspond to the bottom plane of the SLA scraper body 103. Then, push the sliders 200 on both sides to move the pointers 309 and observe the change in the value of the dial indicator 308. When the change in the value of the dial indicator 308 on both sides is within 0.03mm, it indicates that the bottom surface of the SLA scraper body 103 is in a horizontal state. When the measured values ​​of the top and bottom surfaces of the SLA scraper body 103 are both within 0.03mm, it indicates that the SLA scraper body 103 is in a horizontal state.

[0070] In summary: When positioning the SLA scraper body 103, the two Z-shaped rods 708 are manually pulled. The Z-shaped rods 708 move upward, causing the mating teeth 707 to move upward. At this time, the spring 706 is compressed, and the mating teeth 707 separate from the engaging tooth plate 709. Then, the T-shaped bar 700 is pushed. The movement of the T-shaped bar 700 causes the pusher bar 701 to move. The movement of the pusher bar 701 pushes the triangular frame 603 upward. The upward movement of the triangular frame 603 causes the connecting block 601 to move upward. The upward movement of the connecting block 601 pushes the limit blocks 505 on both sides away from each other. Once the distance between the two limiting posts 502 is at a suitable distance, the constraint on the Z-shaped rod 708 is released, and the spring 706 pushes the mating tooth 707, causing the mating tooth 707 to engage with the engaging tooth plate 709. At this time, the distance between the two limiting posts 502 is fixed. Then, the four engaging holes 104 of the SLA scraper body 103 are engaged with the four limiting posts 502. Then, the SLA scraper body 103 is lowered. At this time, the SLA scraper body 103 is between the top surfaces of the two equal-height blocks 102, completing the positioning of the SLA scraper body 103. When the distance between the two limiting posts 502 is reduced, pull up the Z-shaped rod 708 to separate the mating teeth 707 from the engaging tooth plate 709. Then push the two limiting posts 502 closer together. Then release the Z-shaped rod 708 to engage the mating teeth 707 with the engaging tooth plate 709. This completes the reduction of the distance between the two limiting posts 502.

[0071] When testing the levelness of the top surface of the SLA scraper body 103, first place the level 400 at the center of the top surface of the SLA scraper body 103, then start the level 400. The level 400 tests the levelness of the surface of the SLA scraper body 103. When the levelness value of the top surface of the SLA scraper body 103 is within 0.03mm, the top surface of the SLA scraper body 103 is considered to be level.

[0072] When testing the levelness of the two sides of the bottom surface of the SLA scraper body 103, first adjust the positions of the sliders 200 on both sides so that the sliders 200 are in the corresponding positions of the SLA scraper body 103. Then, by rotating the first engagement post 204, guide post 303, first tightening knob 206, and second tightening knob 305 on both sides respectively, make the two pointers 309 correspond to the bottom surface of the SLA scraper body 103. Then, push the sliders 200 on both sides to move the pointers 309 and observe the change in the value of the dial indicator 308. When the change in the value of the dial indicator 308 on both sides is within 0.03mm, it indicates that the bottom surface of the SLA scraper body 103 is in a level state. When the measured values ​​of both the top and bottom surfaces of the SLA scraper body 103 are within 0.03mm, it indicates that the SLA scraper body 103 is in a level state.

[0073] The first tightening knob 206, the second tightening knob 305, the dial indicator 308, and the level 400 can all be purchased from the market. They are mature technologies in this field and have been fully disclosed, so they will not be described again in the instruction manual.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
