Description

Technical Field

[0001] The invention relates to the technical field of glass measurement, and in particular to a go / no-go gauge device and a detection method for glass residual thickness detection. Background Art

[0002] Glass has good transparency and high strength after tempering, so it plays an irreplaceable role in various existing display cabinets. Many display cabinets made of glass splicing require glass of different thicknesses to be processed into a certain angle and then spliced. In order to prevent the appearance of sharp edges, the processed glass must have a certain residual thickness and the back edges must have a certain small chamfer, such as Figure 1 As shown. The accuracy of the residual thickness directly affects the dimensional accuracy of the display cabinet after splicing, so the measurement of the residual thickness is very important. Due to the refraction and reflection of light by glass, it is very difficult to grasp the edges where the two sides intersect when measuring the residual thickness with a conventional caliper, or the foot is stuck on the inclined surface, resulting in inaccurate measurement values ​​and greatly reduced measurement accuracy. For products in large batches, it is easy for inspection personnel to have visual fatigue, making it difficult to quickly determine whether the residual thickness of large batches of glass is qualified. Summary of the invention

Through the mutual cooperation of the fixed clamping foot 1, the fixed plate 2, the adjusting screw 3, the movable clamping foot 4 and the angle fitting plate 5, the go / no-go gauge device can be adjusted to a go gauge or a no-go gauge, which greatly saves the equipment cost. Through the coordinated use of the go gauge and the no-go gauge, it can be quickly determined whether the residual thickness test of a large number of glass is qualified.

[0032] In this embodiment, the fixed clamping foot 1 includes a first positioning surface 101 and a second positioning surface 102. The first positioning surface 101 and the second positioning surface 102 are perpendicular to each other. The intersection line of the first positioning surface 101 and the second positioning surface 102 is a positioning edge line 103. The positioning edge line 103 is used to support the angle bonding plate 5. The first positioning surface 101 is perpendicular to the moving direction of the movable clamping foot 4.

[0033] In this embodiment, a third positioning surface 501 is provided on the angle laminating plate 5 .

[0034] In this embodiment, the fixed clamping foot 1 further includes a T-shaped slot 104 , and the movable clamping foot 4 is slidably connected to the T-shaped slot 104 .

[0035] In this embodiment, two locking nuts 10 are threadedly connected to the adjusting screw 3 . The two locking nuts 10 are respectively located on the left and right sides of the fixing plate 2 . The locking nuts 10 are used to lock the adjusting screw 3 on the fixing plate 2 .

[0036] In this embodiment, a third adjusting nut 11 and a fourth adjusting nut 12 are threadedly connected to the adjusting screw rod 7 , and the third adjusting nut 11 and the fourth adjusting nut 12 are respectively located at the upper and lower sides of the rotating seat 6 .

[0037] In this embodiment, one end of the angle fitting plate 5 is hinged to the movable clamping foot 4 through a positioning pin 13 , and the other end of the angle fitting plate 5 is hinged to the adjusting screw rod 7 through a rotating pin 14 .

[0038] In this embodiment, the movable clamping foot 4 is a transverse T-shaped structure.

[0039] Qualified testing method for residual thickness of glass: Take two sets of the device of the present invention, one set is defined as a through gauge, and the other set is defined as a stop gauge. Set the standard residual thickness of the glass to be tested to G, with an upper deviation value of Es and a lower deviation value of Ei. Put the first positioning surface 101 of the fixed clamping foot 1 of the two sets of devices tightly against the back surface of the glass 01 to be tested, and the second positioning surface 102 of the fixed clamping foot 1 tightly against the top surface of the glass 01 to be tested. By rotating the first adjusting nut 8, the second adjusting nut 9, the third adjusting nut 11 and the fourth adjusting nut 12, the third positioning surface 501 of the angle fitting plate 5 is matched with the inclined surface of the glass 01 to be tested. After adjustment, rotate the loosened third adjusting nut 11 or the fourth adjusting nut 12 to lock the adjusting screw 7. Remove the glass 01 to be tested, rotate the first adjustment nut 8 and the second adjustment nut 9, adjust the movable clamping foot 4 to drive the angle fitting plate 5 to move leftward, so that the third positioning surface 501 of the angle fitting plate 5 is against the positioning edge 103 of the fixed clamping foot 1, and lock the loosened first adjustment nut 8. Use a vernier caliper or micrometer to measure the distance between the two surfaces on the fixed clamping foot 1 and the movable clamping foot 4, such as Figure 4 As shown. Record the reading of the vernier caliper or micrometer at this time. The reading of the go gauge is At, and the reading of the no-go gauge is Az. Loosen the second adjusting nut 9 on the go gauge, rotate the first adjusting nut 8 on the go gauge, and when the distance between the two surfaces on the fixed clamping foot 1 and the movable clamping foot 4 on the go gauge is measured by a vernier caliper or micrometer and the value is At+G+Es, tighten the second adjusting nut 9 on the go gauge. At this time, the go gauge is adjusted. Loosen the second adjusting nut 9 on the no-go gauge, rotate the first adjusting nut 8 on the no-go gauge, and when the distance between the two surfaces on the fixed clamping foot 1 and the movable clamping foot 4 on the no-go gauge is measured by a vernier caliper or micrometer and the value is Az+G+Ei, tighten the second adjusting nut 9 on the no-go gauge. At this time, the no-go gauge is adjusted. The first positioning surface 101 of the fixed foot 1 of the through and stop gauges is pressed against the back of the glass 01 to be tested, and the second positioning surface 102 of the fixed foot 1 is pressed against the top surface of the glass 01 to be tested. If there is a gap a between the inclined surface of the glass 01 to be tested and the third positioning surface 501 of the angle fitting plate 5 on the stop gauge when the stop gauge is used, Figure 5 As shown, or when a through gauge is used, there is a gap b between the second positioning surface 102 of the fixed clamping foot 1 on the through gauge and the tested glass 01. Figure 6As shown, the inspected glass can be directly judged as unqualified. If neither of the above two situations occurs, the inspected glass can be judged as qualified.

[0040] The present invention can also use a go gauge and a feeler gauge for inspection. After adjusting the go gauge as described above, the thickness of the feeler gauge is selected according to |Es-Ei|*Sinθ, and the angle θ is as follows: Figure 1 As shown in FIG. 1 , the first positioning surface 101 of the fixed foot 1 of the through gauge is pressed against the back of the glass 01 to be tested, and the second positioning surface 102 of the fixed foot 1 is pressed against the top surface of the glass 01 to be tested. If the top surface of the glass 01 to be tested and the second positioning surface 102 of the fixed foot 1 on the through gauge cannot be pressed against each other, and there is a gap b, the tested glass is directly judged to be unqualified. Figure 6 When the first positioning surface 101 of the fixed foot 1 of the through gauge is in close contact with the back of the glass 01 to be tested, and the second positioning surface 102 of the fixed foot 1 is in close contact with the top surface of the glass 01 to be tested, there is a gap c between the inclined surface of the glass 01 to be tested and the third positioning surface 501 of the angle fitting plate 5 on the through gauge, use the selected feeler gauge 15 to fill the gap. If it cannot pass, the glass to be tested is qualified; if it can pass, the glass to be tested is unqualified. Figure 7 shown.
