Description

Technical Field

[0001] This application relates to the field of grating testing, and in particular to grating moving test fixtures. Background Technology

[0002] An optical device consisting of a large number of parallel slits of equal width and spacing is called a grating. Commonly used gratings are made by etching a large number of parallel grooves on a glass plate. The grooves are opaque, while the smooth parts between two grooves are transparent, which is equivalent to a slit. Gratings combine digital technology with traditional printing techniques to display different special effects on specially made films. Grating testing requires a platform and has certain requirements for the horizontal and vertical alignment of the testing environment.

[0003] Currently, existing grating testing devices have different wiring terminals for different gratings, which makes measurement inconvenient, grating fixing inconvenient, operation and use inconvenient, and has a limited range of applications. Utility Model Content

[0004] To address the issues of inconvenient measurement, inconvenient grating fixation, inconvenient operation and use, and limited applicability, this application provides a grating moving test fixture.

[0005] The grating moving test frame provided in this application adopts the following technical solution:

[0006] A grating moving test frame includes a frame body. A control box is installed at the bottom of one side of the frame body. A clamping structure for holding the grating is slidably connected to the outer wall of one side of the frame body. The clamping structure includes an L-shaped base. A locking screw is threaded to one end of the base. One end of the locking screw extends into the interior of the base and is movably connected to a movable clamping plate. A fixed clamping plate is provided at the other end of the base. The base is recessed inward to form a groove. A locking mechanism is provided between the frame body and the clamping structure.

[0007] By adopting the above technical solution, the grating to be tested can be quickly fixed, which facilitates the next step of the operation.

[0008] Preferably, there are two frames, one of which has a laser emitter at its top and the other has a target plate corresponding to the laser emitter at its top.

[0009] By adopting the above technical solution, a laser emitter is used to emit a laser towards the target plate for position correction of the target center, so that the positions of the two frames can be accurately aligned.

[0010] Preferably, the outer wall of the control box is provided with multiple wired control interfaces for connecting gratings of different specifications.

[0011] By adopting the above technical solution, this device can meet the interface wiring requirements of gratings of different specifications, thus increasing its applicability.

[0012] Preferably, the locking mechanism includes a pressing block located inside the groove. The upper and lower ends of the frame are provided with through adjustment slots. A connecting rod is fixedly connected to one outer wall of the pressing block. One end of the connecting rod passes through the adjustment slot and extends to the other side of the frame. An arc-shaped locking plate is rotatably connected to one side wall of the connecting rod. A spring is rotatably connected to the side wall of the locking plate away from the connecting rod, and the end of the spring away from the locking plate is rotatably connected to the side wall of the connecting rod. A limit block is fixedly connected to the outer wall of the connecting rod by bolts.

[0013] By adopting the above technical solution, the base and frame can be fixed quickly, improving the ease of operation of the device.

[0014] Preferably, both the movable clamping plate and the fixed clamping plate have sponges bonded to their opposite sides to protect the grating during clamping, and a gap is left between the movable clamping plate and the clamping block.

[0015] By adopting the above technical solution, the sponge can protect the grating during clamping, thus facilitating the movement of the movable clamping plate along the inside of the groove.

[0016] Preferably, the limiting block and the locking plate are located on the same side of the connecting rod, and the angle formed between the limiting block and the connecting rod is between 30 and 50 degrees.

[0017] By adopting the above technical solution, the design of the limiting block can abut against the locking plate when the base does not need to be fixed, thereby facilitating the movement of the base when the pressing block is not in a pressing state.

[0018] Preferably, the spring, the limiting block, the locking plate, and the connecting rod are arranged sequentially away from the frame, and an anti-slip pad is provided at the end of the locking plate away from the connecting rod.

[0019] By adopting the above technical solution, it can be ensured that the base is fixed under the tension of the spring.

[0020] Preferably, the bottom of the frame is provided with a base and a chassis, the bottom end of the frame is fixedly connected to the top end of the chassis, rollers are installed at the four corners of the bottom of the base, the chassis is located above the top of the base, and bolts are respectively provided between the four corners of the chassis and the base, the top end of the bolt extends to the top of the chassis and is threaded with a first adjusting nut, and a second adjusting nut is also threadedly connected to the bolt in the middle section between the base and the chassis.

[0021] By adopting the above technical solution, the horizontal control requirements of the chassis can be achieved by rotating the first adjusting nut and the second adjusting nut.

[0022] Preferably, the base has a through hole for the connecting rod to pass through, and the through hole corresponds to the position of the adjustment groove.

[0023] By adopting the above technical solution, the connecting rod can move up and down along the adjustment groove.

[0024] Preferably, a level is provided at the middle of the top plane of the chassis, and scale lines are also provided on the frame.

[0025] By adopting the above technical solution, the position of the bubble in the level can be observed, making it convenient to adjust the level of the chassis.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. First, emit a laser towards the target plate using a laser emitter. Adjust the position of the frame so that the laser can be aligned with the target center, thus ensuring that the two frames are accurately aligned and guaranteeing the accuracy of the grating test. Place one grating between two bases on the same side and then tighten the adjusting screw to fix the grating. Then place the other grating between two bases on another frame. Connect the wiring terminals of different gratings to the corresponding specification wired control interface. Use a test probe to measure between the two gratings, thereby increasing its applicability.

[0028] 2. With the help of the base that can move up and down along the frame, the distance between the two bases can be adjusted to meet the clamping and fixing needs of gratings of different sizes. When the base is moved to the appropriate position, by rotating the locking plate, the locking plate can be tightly attached to the frame under the tension of the spring. This causes the connecting rod to pull the pressure block closer to the frame and onto the bottom of the groove. When it is necessary to loosen, simply pry the locking plate away from the frame. This allows for quick fixing of the base and facilitates the operation of the device.

[0029] 3. With the help of the set chassis and the level, first adjusting nut and second adjusting nut set on the chassis, the horizontal control requirements of the chassis can be achieved by rotating the first adjusting nut and the second adjusting nut and observing the position of the bubble in the level, which in turn facilitates the vertical adjustment of the frame and the adjustment of the position of the grating fixed on the frame.

[0035] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0036] Reference Figure 1-2 This application discloses a grating moving test frame, including two frames 1. A control box 2 is provided on the bottom side of one side of the frame 1. Multiple wired control interfaces 11 for connecting gratings of different specifications are provided on the outer wall of the control box 2. The inside of the control box 2 is also provided with a storage cavity for storing long cables and test rods. A laser emitter 3 is provided at the top of one frame 1, and a target plate 4 corresponding to the laser emitter 3 is provided at the top of the other frame 1, which facilitates the alignment and adjustment between the two frames 1.

[0037] A clamping structure 5 for holding the grating is slidably connected to one outer wall of the frame 1. The clamping structure 5 includes an L-shaped base 51. One end of the base 51 is threaded with a locking screw 52. One end of the locking screw 52 extends into the interior of the base 51 and is movably connected to a movable clamping plate 53. The other end of the base 51 is provided with a fixed clamping plate 54. The base 51 is recessed inward to form a groove 55. The frame 1 is also provided with a scale line 9 for observing the position of the base 51. A locking mechanism is also provided between the frame 1 and the clamping structure 5.

[0038] Reference Figure 2-3The locking mechanism includes a pressing block 12 located inside the groove 55. The upper and lower ends of the frame 1 are both provided with through-hole adjustment slots 10. A connecting rod 13 is fixedly connected to one outer wall of the pressing block 12. One end of the connecting rod 13 passes through the adjustment slot 10 and extends to the other side of the frame 1. An arc-shaped locking plate 14 is rotatably connected to the side wall of one end of the connecting rod 13. A spring 15 is rotatably connected to the side wall of the locking plate 14 away from the connecting rod 13, and the spring 15 is away from the locking plate 14. One end of the limit block 16 is rotatably connected to the side wall of the connecting rod 13. The limit block 16 is fixedly connected to the outer wall of the connecting rod 13 by bolts. The limit block 16 and the locking plate 14 are located on the same side of the connecting rod 13, and the angle formed between the limit block 16 and the connecting rod 13 is between 30 and 50 degrees. The design of the limit block 16 allows it to abut against the locking plate 14 when the base 51 does not need to be fixed, so that the pressing block 12 can facilitate the movement of the base 51 in the non-pressing state.

[0039] Reference Figure 3 Both the movable clamp 53 and the fixed clamp 54 have sponges 56 glued to their opposite sides to protect the grating during clamping. There is a gap between the movable clamp 53 and the clamping block 12, so that the movable clamp 53 can move along the inside of the groove 55, thereby changing the distance between the movable clamp 53 and the fixed clamp 54, which makes it easier to fix the grating.

[0040] Reference Figure 3 The connection positions of spring 15, limit block 16, locking plate 14 and connecting rod 13 are arranged in sequence away from the frame 1. The end of locking plate 14 away from connecting rod 13 is provided with anti-slip pad, so as to ensure that the base 51 is fixed under the tension of spring 15.

[0041] Reference Figure 4 The frame 1 has a base 7 and a chassis 18 at its bottom. The bottom of the frame 1 is fixedly connected to the top of the chassis 18. Rollers 8 are installed at the four corners of the bottom of the base 7. The chassis 18 is located above the top of the base 7, and bolts are installed between the four corners of the chassis 18 and the base 7. The top of the bolts extends to the top of the chassis 18 and is threaded with a first adjusting nut 17. A second adjusting nut is also threaded on the bolt in the middle section between the base 7 and the chassis 18. A level is installed in the middle of the top plane of the chassis 18. By rotating the first adjusting nut 17 and the second adjusting nut and observing the position of the bubble in the level, the level control requirements of the chassis 18 can be achieved.

[0042] Reference Figure 1-3 The base 51 has a through hole for the connecting rod 13 to pass through, and the through hole corresponds to the position of the adjustment groove 10, so that the connecting rod 13 can move up and down along the adjustment groove 10.

[0043] The implementation principle of this utility model is as follows: First, a laser is emitted from the laser emitter 3 towards the target plate 4. The position of the frame 1 is adjusted so that the laser can be aligned with the target center, thereby ensuring that the two frames 1 are accurately aligned and guaranteeing the accuracy of the grating test. One grating is placed between two bases 51 on the same side, and then the grating is fixed by tightening the adjusting screw 52. Then, another grating is placed between two bases 51 on another frame 1. The wiring terminals of different gratings are connected to the corresponding specification wired control interface 11, thereby increasing its applicability. A test rod is used between the two gratings for testing. Measurement is performed using a base 51 that can move up and down along the frame 1, allowing adjustment of the distance between the two bases 51 to accommodate different sizes of grating clamps. When the base 51 is moved to the appropriate position, rotating the locking plate 14, under the tension of the spring 15, allows the locking plate 14 to be tightly attached to the frame 1. This causes the connecting rod 13 to pull the pressing block 12 toward the frame 1 and onto the bottom of the groove 55. When it is necessary to loosen the clamp, simply pry the locking plate 14 away from the frame 1, thus quickly fixing the base 51 and facilitating the operation of the device.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
