[0002] Special-shaped glass cover plates have been widely used in life, such as various utensils, handicrafts, digital product casings, etc. In the design and manufacturing process of glass cover plates, due to the requirements of product parameters, it is often necessary to measure the size of the glass cover plate, such as important parameters such as the surface arc length and perimeter. However, common measuring jigs such as tape measures and calipers are not well applicable to the curved surface measurement of special-shaped glass cover plates.

This measurement method often has a large measurement error due to insufficient fitting degree. In addition, when measuring the perimeter, it is often difficult to take points and measure because there is no effective clamping device for the curved surface of the special-shaped glass cover.

[0030] When the operator is inspecting the arc length dimension of the special-shaped glass cover plate, after fixing the special-shaped glass 3, the operator slowly rolls along the upper surface of the special-shaped glass 3 by toggling the arc length measuring device 6, and the arc length measuring roller 604 contacts the surface of the special-shaped glass 3.

A stud 101 is fixedly connected to one side wall of the caliper 10. A guide slider 102 is fixedly connected to one end of the stud 101. An adjusting knob 103 is sleeved on the outer wall of the stud 101. A clamping knob 104 is movably connected to the side wall of the caliper 10 adjacent to the stud 101. The clamping knob 104 is coaxially connected to a gear three 105. A gear four 106 is meshed with the outer wall of the gear three 105. The gear four 106 is coaxially connected to a clamp head 107. The clamp head 107 is spherical and made of rubber. A tray 108 is fixedly connected to the bottom end of the caliper 10. The clamp head 107 is located above the tray 108.

[0032] When the operator measures the surface arc length of the special-shaped glass 3, first move the adjusting slider 901 to a general position on the upper surface of the base 1, then place the special-shaped glass 3 above the tray 108 at the bottom end of the caliper 10. Then, according to the measured size of the special-shaped glass 3, the operator adjusts the clamping knob 104 to clamp the special-shaped glass 3, adjusts the height of the caliper 10 through the adjusting knob 103, and adjusts the position of the clamping rod 9 on the upper surface of the base 1 through the set screw 902 and fixes it, so as to ensure the stability and firmness of the special-shaped glass 3 during the measurement process.

[0033] As Figure 1-6 As shown in the figure, guide grooves 701 are respectively provided on the upper and lower surfaces of the perimeter measurer 7. A rotating shaft 702 is slidably connected to the inner wall of the guide groove 701. A small spring 703 is movably connected inside the guide groove 701. The bottom end of the small spring 703 abuts against the perimeter measurer 7, and the top end of the small spring 703 abuts against the rotating shaft 702. A perimeter scale 704 is fixedly connected to the upper surface of the perimeter measurer 7. A perimeter measuring roller 705 is sleeved on the outer wall of the rotating shaft 702. The perimeter measuring roller 705 is made of frosted material. A gear five 706 is coaxially fixedly connected to the bottom end of the perimeter measuring roller 705. A gear six 707 is meshed with the outer wall of the gear five 706. A perimeter pointer 708 is coaxially fixedly connected to the gear six 707. The perimeter pointer 708 is rotatably connected inside the perimeter scale 704. The suction cup 2 is internally provided with an air pipe 201. An air pump 202 is fixedly connected to the outer wall of the suction cup 2. The input port of the air pump 202 is fixedly connected to the air pipe 201. The bottom end of the suction cup 2 is fixedly connected to the output shaft of the driving motor 4 through a bearing. The driving motor 4 is fixedly connected to the lower surface of the base 1.

[0034] When the operator measures the perimeter of the special-shaped glass 3, first adjust the above-mentioned adjusting clamping rod 9 to retract to a suitable position, then adsorb the special-shaped glass 3 on the upper surface of the suction cup 2, and extract the air inside the suction cup 2 through the air pump 202 and the air pipe 201, so that the special-shaped glass 3 is tightly adsorbed on the upper surface of the suction cup 2. Then, clamp the perimeter measuring device 7 on the side wall of the special-shaped glass 3. Due to the elastic force of the small spring 703, the perimeter measuring roller 705 will be in close contact with the outer wall of the special-shaped glass 3. The operator starts the driving motor 4. During the slow rotation of the driving motor 4, the suction cup 2 fixed to the output end of the driving motor 4 drives the special-shaped glass 3 to rotate slowly. At this time, the perimeter measuring roller 705 in close fit with it rotates around the rotating shaft 702. During the rotation process, the fifth gear 706 coaxially connected to the perimeter measuring roller 705 starts to rotate slowly, driving the meshing sixth gear 707 to start rotating. The rotating distance is reflected on the perimeter scale 704 through the perimeter pointer 708. After the driving motor 4 rotates one week, the perimeter value can be read out.

[0035] Working principle: The overall structure of the device can be used to measure the arc length and circumference of the shaped glass cover. When measuring the arc length, first place the shaped glass 3 on the clamping rod 9, tighten the shaped glass 3 through a pair of clamping rods 9, and then push the arc length measuring device 6 along the bracket to a certain section, and start to push the arc length measuring device 6 to slowly roll on the upper surface of the shaped glass 3. After the entire upper surface of the shaped glass 3 is rolled, the arc length value can be read. When measuring the circumference of the shaped glass 3, the suction cup 2 is used to tightly adsorb the lower surface of the shaped glass 3, and the side wall of the shaped glass 3 is sleeved in the circumference measuring device 7, and then the driving motor 4 is started to slowly rotate the shaped glass 3. After one circle of rotation, the circumference value can be read from the circumference measuring device 7. The operator When detecting the arc length dimension of the special-shaped glass cover plate, after fixing the special-shaped glass 3, the arc length measuring device 6 is toggled to slowly roll along the upper surface of the special-shaped glass 3, and the arc length measuring roller 604 contacts the surface of the special-shaped glass 3. Under the elastic force of the spring 601, the arc length measuring roller 604 always fits tightly with the surface of the special-shaped glass 3. During the rolling process, the guide block 602 at the top of the arc field measuring device 7 slides along the guide groove 502 inside the bracket 5, thereby ensuring the straightness when measuring the arc length. During the measurement process, the arc length measuring roller 604 rolls to drive the gear 1 605 to rotate, and the gear 2 606 meshing with it rotates synchronously, so that the number of rotations is reflected on the arc length scale 603 through the arc length pointer 607, and the surface arc length measurement of the special-shaped glass 3 is completed. When the operator detects the surface arc length of the special-shaped glass 3, he first adjusts the slider 901 on the upper surface of the base 1 to an approximate position, and then places the special-shaped glass 3 on the tray 108 at the bottom of the caliper 10. Then, according to the measured size of the special-shaped glass 3, the operator adjusts the clamping knob 104 to clamp the special-shaped glass 3, adjusts the height of the caliper 10 by adjusting the knob 103, adjusts the position of the clamping rod 9 on the upper surface of the base 1 by the set screw 902, and fixes it, so as to ensure the stability and fastening of the special-shaped glass 3 during the measurement process. When measuring the circumference of the special-shaped glass 3, the operator first adjusts the above-mentioned adjustment clamping rod 9 to retreat to a suitable position, and then adsorbs the special-shaped glass 3 on the upper surface of the suction cup 2, and uses the air pump 202 and the air pipe to adjust the special-shaped glass 3. 201 extracts the air inside the suction cup 2 so that the shaped glass 3 is tightly adsorbed on the upper surface of the suction cup 2, and then the circumference measuring device 7 is clamped on the side wall of the shaped glass 3. Through the elastic force of the small spring 703, the circumference measuring roller 705 will be in close contact with the outer wall of the shaped glass 3. The operator starts the driving motor 4. During the slow rotation of the driving motor 4, the suction cup 2 fixed to the output end of the driving motor 4 drives the shaped glass 3 to rotate slowly. At this time, the circumference measuring roller 705 tightly fitted therewith rotates around the rotating shaft 702. During the rotation, the gear five 706 coaxially connected to the circumference measuring roller 705 starts to rotate slowly, driving the gear six 707 meshing therewith to start rotating. The rotation distance is reflected on the circumference dial 704 through the circumference pointer 708.After the drive motor 4 rotates one full circle, the perimeter value can be read out.
