[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 5 As shown, this utility model discloses a glass inspection fixture, including a main body 1 and a positioning block 2. The main body 1 is provided with a detection space 11 and a plurality of positioning platforms 12 surrounding the detection space 11. The upper surface 121 of each positioning platform 12 is of equal height. The positioning block 2 is provided with a support leg 21 that abuts against the end face of the positioning platform 12 away from the detection space 11. The positioning block 2 is provided with a positioning surface 23 that abuts against the upper surface 121. The positioning block 2 is provided with a through hole 22.

[0018] Working principle: During testing, the glass 8 is first positioned in the testing space 11. Then, the operator inserts the probe of a dial indicator or micrometer through the perforation 22 on the positioning block 2 and fixes it in place. The support 21 of the positioning block 2 is then directly abutted against a positioning platform 12 set around the testing space 11 on the main body 1, and the positioning surface 23 is attached to the upper surface 121 of the corresponding positioning block 2. This allows for quick and accurate positioning of the inspection tool at the testing point, enabling measurement. After testing at a point, the same set of positioning blocks 2 (along with the inspection tool on them) is moved to another positioning platform 12 on the main body 1 for abutment and positioning, allowing measurement at the next point. This cycle is repeated, utilizing the shared positioning platform 12 and the movable positioning blocks 2. Without the need for an independent support for each testing point, the testing of all specified dimensions of the glass 8 can be completed efficiently.

[0019] It is worth noting that different shapes of positioning blocks 2 are selected and assembled with inspection tools to meet different measurement requirements. For example... Figure 6As shown, when inspecting the surface profile of glass 8, an L-shaped positioning block 2 can be used to place the probe of the inspection tool on the surface of glass 8. Figure 7 As shown, when inspecting the edge profile of the glass 8, a rectangular positioning block 2 can be used to place the probe of the inspection tool on the edge of the glass 8.

[0020] In some implementations, please refer to Figure 3 As shown, a barrier 13 is provided on the main body 1, which encloses the main body 1 to form a detection space 11. The barrier 13 has a clearance opening 131 at the corresponding positioning platform 12. The detection space 11 is formed by the barrier 13 according to the contour shape of the glass 8. At the same time, the clearance opening 131 ensures that the probe of the inspection tool can pass through the barrier 13 and extend into the detection space 11 to contact the edge of the glass 8.

[0021] It is worth noting that when inspecting batches of glass 8, the edge profile of glass 8 is checked using go / no-go gauges. Therefore, a gap should be left between the enclosure 13 and the edge of glass 8 for go / no-go gauge inspection. Generally, a 3mm gap should be left between the enclosure 13 and the edge of the standard glass. Of course, the specific value of this gap is determined based on the dimensions of the go and no-go ends of the go / no-go gauge.

[0022] During operation, first insert the go end of the go gauge into the gap between the enclosure 13 and the glass 8, and let it slide smoothly along the glass contour for more than one revolution; if the sliding is obstructed, the glass edge contour does not meet the requirements. If the go end slides smoothly, then try to insert the stop end into the gap and move it along the glass contour for more than one revolution; if the stop end can be inserted, it is also determined that the glass edge contour does not meet the requirements.

[0023] In some implementations, please refer to Figure 8 As shown, the edge of the detection space 11 is provided with positioning pins 3 along its own contour. The positioning pins 3 abut against the edge of the glass 8, which helps the operator to quickly position the glass 8 within the detection space 11.

[0024] It is worth noting that, please refer to Figure 8 As shown, the glass inspection fixture also includes a mounting base 4, on which the positioning pin 3 is detachably mounted. The positioning pin 3 is installed in a detachable manner, allowing for periodic replacement and preventing deformation of the positioning pin 3 due to prolonged use, which could affect the positioning accuracy of the glass 8 in the inspection space 11. The connection between the positioning pin 3 and the mounting base 4 can be a threaded connection or an interference fit insertion method.

[0025] In some implementations, please refer to Figure 9 As shown, the edge of the detection space 11 is provided with support columns 5 along its own contour. The support columns 5 are used to support the glass 8 below to ensure the stability of the glass 8 within the detection space 11.

[0026] In some implementations, please refer to Figure 9 As shown, the glass inspection fixture also includes clamps 6, which have grippers that move toward the support surface of the support column 5. The clamps 6 can fix the glass 8 within the inspection space 11, preventing the glass 8 from moving during the inspection process.

[0027] In some implementations, please refer to Figures 11 to 13 As shown, the clamp 6 includes a clamp base 61, a clamp bar 62, a fixing pin 63, and a spring 64. The clamp base 61 has a pin hole 611 and a limiting groove 612 on its top surface. One end of the clamp bar 62 is located in the limiting groove 612, and the other end of the clamp bar 62 has a pressing block 621 for pressing against the surface of the glass 8. One end of the fixing pin 63 passes through the clamp bar 62 and is interference-fitted with the pin hole 611, allowing the clamp bar 62 to move in and out of the limiting groove 612 along the length of the fixing pin 63. The other end of the fixing pin 63 has a limiting cap 631. The spring 64 is sleeved on the fixing pin 63 and is compressed between the limiting cap 631 and the clamp bar 62. During use, because the spring 64 is compressed between the limiting cap 631 and the clamp bar 62, the pressing block 621 on the clamp bar 62 is pressed against the surface of the glass 8 under the action of the spring force of the spring 64. When it is necessary to remove the glass 8, the clamp 62 is lifted along the length of the fixing pin 63 to further compress the spring 64, thereby allowing the clamp 62 to exit the limiting groove 612. Then, the clamp 62 can be rotated with the fixing pin 63 as the rotating axis, thereby moving the pressure block 621 away from the glass 8.

[0028] It is worth noting that when supporting glass 8 with a certain curvature, the supporting surface of the support column 5 can be set as an arc surface, which helps the support column 5 support the glass 8. When supporting glass 8 with a small curvature or a flat surface, the supporting surface of the support column 5 can be set as a plane, which helps the support column 5 support the glass 8.

[0029] In some implementations, please refer to Figure 10 As shown, the glass inspection tool also includes a zeroing block 7, which has a second positioning surface 71 that abuts against the support leg 21. The zeroing block 7 is provided with a zeroing part 72, one end of the zeroing part 72 facing the second positioning surface 71 being a first zeroing surface 721, and the other end of the zeroing part 72 away from the zeroing block 7 being a second zeroing surface 722. Before inspection, when inspecting the surface contour of the glass 8, the inspection tool is used as follows... Figure 4 As shown, the positioning block 2 is assembled, and then the support leg 21 of the positioning block 2 is placed against the second positioning surface 71 of the zeroing block 7, and the positioning surface 23 is placed against the surface of the zeroing block 7 where the zeroing part 72 is provided, so that the probe of the inspection tool is placed against the second zeroing surface 722 for zeroing. When inspecting the edge line contour of the glass 8, the inspection tool is used as shown. Figure 5The positioning block 2 is assembled, and then the support 21 of the positioning block 2 is placed against the second positioning surface 71 of the zeroing block 7, and the positioning surface 23 is placed against the surface of the zeroing block 7 where the zeroing part 72 is provided, so that the probe of the inspection tool is placed against the first zeroing surface 721 for zeroing. Zeroing the inspection tool before testing can ensure the accuracy of subsequent inspection.

[0030] In some implementations, please refer to Figure 1 As shown, the testing space 11 is provided with a mounting slot 111 that is compatible with the zero-calibration block 7. The zero-calibration block 7 can be stored in the testing space 11 through the mounting slot 111 for easy management and use.

[0031] In some implementations, please refer to Figure 1 As shown, the inspection space 11 is equipped with a clamp 112 for holding inspection tools. The clamp 112 can store the inspection tools in the inspection space 11 for easy management and use.

[0032] It is worth noting that the clamp 112 is a device that uses spring force to hold objects, such as spring clamps or spring pliers.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
