Description

Technical Field

[0001] This utility model relates to a glass curvature measuring device, belonging to the field of glass curvature measuring equipment. Background Technology

[0002] Glass curvature is the maximum deviation of the glass surface from an ideal plane, calculated using the formula: Curvature = h / L, where h represents the arch height and L represents the chord length. Glass curvature is a crucial parameter for assessing glass manufacturing quality, directly affecting its optical and mechanical properties. Therefore, curvature measurement is typically performed after glass production. Traditional glass curvature measurement usually involves first placing the glass flat on a standard horizontal platform in its natural state (without external force) to ensure no additional pressure causes deformation. Then, a feeler gauge is used to measure the gap between the glass's center point or the point of maximum curvature and the platform (i.e., the maximum arch height h). Finally, the chord length (L) corresponding to the arch height is selected along the curvature direction to calculate the glass curvature. Because this process requires repeated trials using feeler gauges of varying thicknesses, it is cumbersome and inefficient.

[0003] To address this, Chinese utility model patent CN219328409U discloses a glass curvature measuring device. While the aforementioned prior art conveniently achieves the measurement of glass curvature, it still has the following drawbacks: First, when the glass is naturally placed on a table, if the glass area is large and the weight is heavy, the glass is prone to deformation due to its own weight, thus affecting the accuracy of the measurement results; second, after the glass is placed, the dial indicator cannot move back and forth, so only one position of the glass can be measured. If other positions of the glass need to be measured, the glass needs to be moved and repositioned, making the operation cumbersome. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a glass curvature measuring device with more accurate measurement results and more convenient measurement operation.

[0005] The glass curvature measuring device of this utility model includes a base. Two guide pillars and multiple support grooves are fixedly connected to the top of the base. The two guide pillars are located on the left and right sides of the base, respectively. Each support groove is located between the two guide pillars. A crossbeam is fixedly connected between the tops of the two guide pillars. Upper and lower sliding sleeves are slidably fitted on each of the two guide pillars. A mounting plate is fixedly connected between the two upper sliding sleeves. Multiple slots corresponding to the support grooves are fixedly connected on the mounting plate. Locking components are connected between the two lower sliding sleeves and the two guide pillars. A guide shaft is fixedly connected between the two lower sliding sleeves. A slider is slidably fitted on the guide shaft. A dial indicator mounting base is fixedly connected to the slider. A dial indicator is detachably mounted on the dial indicator mounting base.

[0006] Furthermore, magnets are connected to the top of the mounting plate and the bottom of the crossbeam.

[0007] Furthermore, the locking component is a set screw threaded onto the side wall of the lower sleeve, with the inner end of the set screw penetrating the side wall of the lower sleeve and abutting against the guide post.

[0008] Furthermore, both the support groove and the card slot have chamfered edges at their ports.

[0009] Furthermore, a protective pad is installed inside the support groove.

[0010] Furthermore, the guide shaft is a regular polygon, and the slider has a regular polygonal sliding hole that matches the guide shaft.

[0011] Furthermore, the guide shaft is a regular hexagon.

[0012] Working principle and process:

[0013] In use, place the lower edge of the glass to be tested into each support groove, then pull down the mounting plate to disengage it from the magnetic attraction of the crossbeam. Continue pulling down the mounting plate to engage the slots with the upper edge of the glass. With the cooperation of the support grooves and the slots, the glass is stably placed. Then, install the dial indicator on the dial indicator mounting base and place the dial indicator probe against the glass. By sliding the slider left and right, the dial indicator can be moved left and right to measure the maximum and minimum values, thus calculating the curvature of the glass. To measure the curvature at different locations, the height of the sliding sleeve can be adjusted by adjusting the set screw, thereby adjusting the height of the dial indicator to measure the curvature at different locations on the glass.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The glass curvature measuring device of this invention places the glass vertically, thereby preventing the glass from deforming due to its own weight and effectively ensuring the accuracy of curvature measurement; the height of the dial indicator can be adjusted, so that the curvature at different positions of the glass can be measured without moving the glass, making the operation simple and convenient.

[0023] like Figures 1 to 4 As shown, the glass curvature measuring device of this utility model includes a base 1. Two guide pillars 4 and multiple support grooves 2 are fixedly connected to the top of the base 1. The two guide pillars 4 are located on the left and right sides of the base 1, respectively. Each support groove 2 is located between the two guide pillars 4. A crossbeam 10 is fixedly connected between the tops of the two guide pillars 4. Upper sliding sleeves 7 and lower sliding sleeves 6 are slidably fitted on each of the two guide pillars 4. A mounting plate 11 is fixedly connected between the two upper sliding sleeves 7. Multiple slots 8 corresponding to the support grooves 2 are fixedly connected on the mounting plate 11. Locking components are connected between the two lower sliding sleeves 6 and the two guide pillars 4. A guide shaft 12 is fixedly connected between the two lower sliding sleeves 6. A slider 15 is slidably fitted on the guide shaft 12. A dial indicator mounting base 13 is fixedly connected to the slider 15. A dial indicator 14 is detachably installed on the dial indicator mounting base 13.

[0024] In use, place the lower edge of the glass 3 to be tested into each support groove 2, and then pull down the mounting plate 11 so that each slot 8 is locked into the upper edge of the glass 3. With the cooperation of each support groove 2 and slot 8, the glass 3 is stably placed. Then, install the dial indicator 14 on the dial indicator mounting base 13 and make the probe of the dial indicator 14 rest against the glass 3. By sliding the slider 15 left and right, the dial indicator 14 can be moved left and right, so as to measure the maximum and minimum values ​​of the dial indicator and calculate the curvature of the glass 3. If the curvature at different positions is to be tested, the height of the sliding sleeve 6 can be adjusted by the locking component, so as to adjust the height position of the dial indicator 14 and realize the curvature measurement at different positions of the glass 3.

[0027] Furthermore, magnets 9 are connected to the top of the mounting plate 11 and the bottom of the crossbeam 10 respectively. Before placing the glass 3, the mounting plate 11 can be attached to the crossbeam 10 to facilitate the placement of the glass 3.

[0028] Furthermore, the locking component is a set screw 5 threaded onto the side wall of the sliding sleeve 6. The inner end of the set screw 5 penetrates the side wall of the sliding sleeve 6 and abuts against the guide post 4. The sliding sleeve 6 can be moved and locked by rotating the set screw 5, which is simple in structure and easy to operate.

[0029] Furthermore, both the support groove 2 and the slot 8 have chamfers 16 at their ports to facilitate the insertion of the glass 3 into the support groove 2 or the slot 8.

[0030] Furthermore, a protective pad 17 is installed inside the support groove 2, which can effectively prevent the edge of the glass 3 from being worn and play a protective role.

[0031] Furthermore, the guide shaft 12 is a regular polygon, preferably a regular hexagon, and the slider 15 has a regular polygonal sliding hole that matches the guide shaft 12. This ensures that the slider 15 slides smoothly while preventing it from rotating.
