Technical Field
[0001] This application relates to the technical field of testing fixtures for automotive light shields, and in particular to a testing fixture for a light shield. Background Technology
[0002] Light-blocking strips are widely used in numerous optical devices, electronic equipment, and the automotive industry. Their quality and performance directly affect the normal operation and effectiveness of these devices. During the production process, various performance tests are required to ensure that light-blocking strips meet quality standards. Automotive light-blocking strips are irregular parts with a pivot; to improve the accuracy of these parts, manufacturers use projectors to measure their dimensions.
[0003] Regarding the aforementioned technologies, it has been found that traditional factories mostly use projectors for inspection. In reality, after manufacturers send the produced light-blocking strips to users, users also need to measure the size of the light-blocking strips. Usually, users do not have projectors and cannot measure the size of the light-blocking strips more effectively through simple measurement methods, which is an area that needs improvement. Utility Model Content
[0004] To enable easy and convenient testing of automotive light-blocking strips, this application provides a testing fixture for light-blocking strips.
[0005] The testing fixture for a light-blocking strip provided in this application adopts the following technical solution:
[0006] A testing fixture for a light-blocking strip includes a testing base, which comprises a base plate, a first side plate, and a second side plate. The first and second side plates are vertically mounted on opposite sides of the base plate and are integrally formed. An adjustable solenoid frame is horizontally mounted in the first side plate, and a first clamping frame is mounted in the adjustable solenoid frame. The first clamping frame is threadedly connected to the adjustable solenoid frame. A second clamping frame corresponding to the first clamping frame is horizontally mounted in the second side plate. A vertical pressure frame that can slide back and forth is also provided on the base plate.
[0007] By adopting the above technical solution, the test stand uses an integrated base plate, first side plate, and second side plate structure, ensuring the overall stability and strength of the test stand and guaranteeing the stability of the light-blocking strip during testing. The threaded connection design of the adjustable solenoid frame and the first clamping frame allows the first clamping frame to be flexibly adjusted according to the length of the light-blocking strip, facilitating the clamping of light-blocking strips of different lengths. The second clamping frame corresponds to the first clamping frame, providing support and fixation for the light-blocking strip from the other side, improving the fixation effect. The vertical pressure frame can slide back and forth, allowing it to abut against the side wall corresponding to the light-blocking strip, ensuring the light-blocking strip is in a stable vertical state, facilitating the operator's inspection of the light-blocking strip's dimensions.
[0008] Optionally, the upper surface of the base plate is provided with a guide groove for sliding installation of the vertical pressure frame, the first side plate is provided with a first horizontal groove for installation of the adjustable screw tube frame, and the second side plate is provided with a second horizontal groove for installation of the second clamping frame.
[0009] By adopting the above technical solution, the guide groove on the base plate provides precise guidance for the sliding of the vertical pressure frame, ensuring the smoothness and accuracy of the vertical pressure frame's sliding. The first horizontal groove and the second horizontal groove provide suitable positions for the installation of the adjustable solenoid frame and the second clamping frame, respectively, making the installation of each component more stable and improving the overall performance of the testing fixture.
[0010] Optionally, the adjustable solenoid bracket includes a first auxiliary bearing and a threaded tube. The outer ring of the first auxiliary bearing is engaged and fixed in a first horizontal groove, and the threaded tube is installed in the first auxiliary bearing and fixed to the inner ring of the first auxiliary bearing.
[0011] By adopting the above technical solution, the first auxiliary bearing in the adjustable solenoid frame can ensure that the workpiece can be flexibly rotated and adjusted after clamping, thus facilitating the easy rotation of the light-blocking strip to be inspected to a vertical position for height measurement.

[0018] Optionally, the second clamping frame includes a second auxiliary bearing and a stepped support rod, wherein the second auxiliary bearing is fixedly installed in the second horizontal groove and is sleeved and fixed on the stepped support rod.
[0019] By adopting the above technical solution, the second auxiliary bearing in the second clamping frame allows the stepped support rod to rotate flexibly, enabling better clamping of the other end of the light-blocking strip and improving the support effect of the light-blocking strip. The second auxiliary bearing is fixedly installed in the second horizontal groove, ensuring the installation stability of the second clamping frame and facilitating the flexible flipping of the light-blocking strip after clamping.
[0020] Optionally, the vertical pressure frame includes a movable seat and a positioning vertical piece. The movable seat has sliders integrally formed at both ends that cooperate with the guide groove, and the upper surface of the movable seat is evenly provided with a plurality of insertion holes. The lower end of the positioning vertical piece is inserted and fixed in the insertion holes.
[0021] By adopting the above technical solution, the movable seat of the vertical pressure frame achieves forward and backward sliding of the vertical pressure frame through the cooperation of the slider and the guide groove. The insertion holes on the movable seat facilitate the installation and removal of the positioning vertical pieces. Operators can select the appropriate number and position of positioning vertical pieces according to the specific situation of the light-blocking strip to more accurately fix the light-blocking strip vertically.
[0022] In summary, this application includes at least one of the following beneficial technical effects: The integrated design of the test fixture and the reasonable installation method of each component ensure the structural stability of the entire test fixture, enabling it to withstand various forces during the testing process and reducing testing errors caused by fixture shaking.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a testing fixture for a light-blocking strip. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a testing fixture for a light-blocking strip includes a testing base 1. The testing base 1 includes a base plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are respectively vertically installed on both sides of the base plate 11, and the base plate 11, the first side plate 12, and the second side plate 13 are integrally formed. An adjustable solenoid frame 2 is horizontally installed in the first side plate 12, and a first clamping frame 3 is installed in the adjustable solenoid frame 2. The first clamping frame 3 is threadedly connected to the adjustable solenoid frame 2. A second clamping frame 4 corresponding to the first clamping frame 3 is horizontally installed in the second side plate 13. A vertical pressure frame 5 that can slide back and forth is also provided on the base plate 11. The testing base 1 adopts an integrally formed base plate 11, first side plate 12, and second side plate 13 structure, which ensures the overall stability and strength of the testing base 1 and can withstand the stability of clamping the light-blocking strip during the testing process. The threaded connection design of the adjustable screw tube bracket 2 and the first clamping bracket 3 allows the first clamping bracket 3 to be flexibly adjusted according to the length of the light-blocking strip, facilitating the clamping of light-blocking strips of different lengths. The second clamping bracket 4 corresponds to the first clamping bracket 3, providing support and fixation for the light-blocking strip from the other side, improving the fixing effect of the light-blocking strip. The vertical pressure bracket 5 can slide back and forth, allowing it to abut against the corresponding side wall of the light-blocking strip, ensuring the light-blocking strip is in a stable vertical state, facilitating the inspection of the light-blocking strip's dimensions by staff. The upper end face of the base plate 11 has a guide groove 111 for the sliding installation of the vertical pressure bracket 5, the first side plate 12 has a first horizontal groove for the installation of the adjustable screw tube bracket 2, and the second side plate 13 has a second horizontal groove for the installation of the second clamping bracket 4. The guide groove 111 on the base plate 11 provides precise guidance for the sliding of the vertical pressure bracket 5, ensuring the smoothness and accuracy of the sliding of the vertical pressure bracket 5. The first and second horizontal slots provide suitable positions for the installation of the adjustable solenoid bracket 2 and the second clamping bracket 4, respectively, making the installation of each component more stable and improving the overall performance of the testing fixture. An auxiliary outer plate 14 is fixedly installed on the outer surface of the first side plate 12. A support sleeve 141 for supporting the long screw 31 is provided on the inner surface of the auxiliary outer plate 14, and the support sleeve 141 is integrally formed with the auxiliary outer plate 14. The support sleeve 141 on the auxiliary outer plate 14 provides auxiliary support for the long screw 31, reducing bending deformation of the long screw 31 under stress and improving its stability and service life. At the same time, the integral formation of the support sleeve 141 with the auxiliary outer plate 14 ensures the strength and stability of the support structure.
[0032] Reference Figure 3As shown, the adjustable solenoid frame 2 includes a first auxiliary bearing 21 and a threaded tube 22. The outer ring of the first auxiliary bearing 21 is engaged and fixed in a first horizontal groove. The threaded tube 22 is installed in the first auxiliary bearing 21 and is fixed to the inner ring of the first auxiliary bearing 21. The first auxiliary bearing 21 in the adjustable solenoid frame 2 ensures that the workpiece can be flexibly rotated and adjusted after clamping, thus facilitating the vertical height measurement of the light-blocking strip to be inspected. Simultaneously, the engagement and fixation of the outer ring of the first auxiliary bearing 21 in the first horizontal groove ensures the installation stability of the adjustable solenoid frame 2.
[0033] Reference Figure 2 As shown, the first clamping frame 3 includes a long screw 31 and a locking nut 32. The long screw 31 is threaded into the threaded tube 22, and both ends of the long screw 31 extend out of the threaded tube 22. The locking nut 32 is threaded onto the long screw 31. The long screw 31 of the first clamping frame 3 is threaded into the threaded tube 22. By rotating the long screw 31, the first clamping frame 3 can move left and right, thereby adjusting the clamping force on the light-blocking strip. The locking nut 32 can be locked after the long screw 31 is adjusted to a suitable position to prevent the long screw 31 from loosening during the test, ensuring the fixing effect of the light-blocking strip. At the same time, it is convenient to prevent loosening when rotating through the first auxiliary bearing 21 after clamping the light-blocking strip. An operating handle 311 is installed on the outer end of the long screw 31. The operating handle 311 is fixedly connected to the long screw 31, and several anti-slip grooves 312 are formed on the outer surface of the operating handle 311. The operating handle 311 at the outer end of the long screw 31 facilitates the operator's rotation of the long screw 31, improving operational convenience. The anti-slip groove 312 on the outer surface of the operating handle 311 increases the friction between the hand and the operating handle 311, preventing hand slippage during operation and further improving operational safety and accuracy.
[0034] Reference Figure 4 As shown, the second clamping frame 4 includes a second auxiliary bearing 41 and a stepped support rod 42. The second auxiliary bearing 41 is fixedly installed in the second horizontal groove and is sleeved and fixed on the stepped support rod 42. The second auxiliary bearing 41 in the second clamping frame 4 allows the stepped support rod 42 to rotate flexibly, enabling better clamping of the other end of the light-blocking strip and improving the support effect of the light-blocking strip. The fixed installation of the second auxiliary bearing 41 in the second horizontal groove ensures the installation stability of the second clamping frame 4 and facilitates flexible flipping of the light-blocking strip after clamping.
[0035] Reference Figure 5As shown, the vertical pressure frame 5 includes a movable base 51 and a positioning vertical piece 52. The movable base 51 has integrally formed sliders 511 at both ends that mate with guide grooves 111. The upper surface of the movable base 51 has several evenly spaced insertion holes 512, and the lower end of the positioning vertical piece 52 is inserted and fixed into these insertion holes 512. The movable base 51 of the vertical pressure frame 5 achieves forward and backward sliding through the cooperation of the sliders 511 and guide grooves 111. The insertion holes 512 on the movable base 51 facilitate the installation and removal of the positioning vertical piece 52. Operators can select appropriate positions to install the positioning vertical piece 52 according to the specific conditions of the light-blocking strip, allowing for more precise vertical fixation of the light-blocking strip.
[0036] The implementation principle of a test fixture for a light-blocking strip according to an embodiment of this application is as follows: When using this test fixture, the light-blocking strip is first placed between the first clamping frame 3 and the second clamping frame 4. The position of the first clamping frame 3 is adjusted by rotating the operating handle 311 so that it clamps the light-blocking strip together with the second clamping frame 4. Then, the locking nut 32 is used to lock it. Next, according to the position and shape of the light-blocking strip, the vertical pressure frame 5 is slid to a suitable position, and the positioning vertical piece 52 is inserted into the appropriate insertion hole 512. The operator abuts the positioning vertical piece 52 against the side wall of the light-blocking strip to position the light-blocking strip. Then, the height of the highest point of the light-blocking strip is measured with a height gauge. If the height is within the specified tolerance range, it indicates that the size of the part is qualified.
[0037] 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.
