Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-6, a glass surface curvature measurer comprises a fixed ruler 1 and an electronic dial indicator 2, wherein a mounting groove 3 is vertically arranged at the central position of the upper end of the fixed ruler 1, a measuring rod 201 fixedly mounted at the lower end of the electronic dial indicator 2 is inserted into the mounting groove 3 and fixedly mounted through a fixing component 4, a measuring head 202 is arranged at the lower end of the measuring rod 201, a mounting hole 5 is arranged at the lower side of the fixed ruler 1, the mounting hole 5 and the mounting groove 3 are coaxially arranged, a supporting plate 6 is arranged on the inner side wall of the upper end of the mounting hole 5, a probe 7 is movably mounted in the mounting hole 5, the upper end of the probe 7 is connected with the lower end of the measuring head 202, a spring 8 is mounted between the lower side of the supporting plate 6 and the upper end of the probe;

the upper end of probe 7 is provided with recess 9, and gauge head 202 and recess 9 inside clearance fit, the lateral wall of probe 7 are close to the lower extreme position and run through to be provided with first screw 10 in the recess 9, and first screw 10 internally mounted has first screw 11, and the rubber pad is installed to the end of first screw 11.

The fixing component 4 comprises a fixing hole 401, the fixing hole 401 is arranged on the front side of the fixed ruler 1 and penetrates through the mounting groove 3, a second screw hole 402 is formed in the side wall of the measuring rod 201, a second screw 403 is installed in the fixing hole 401, and the second screw 403 is in threaded assembly with the second screw hole 402.

The working principle is as follows: when the curvature of the surface of the glass needs to be measured, the glass is vertically placed, then a detection person holds the fixed ruler 1 by hand, the lower side edge of the fixed ruler 1 is tightly attached to the surface of the glass, the probe 7 at the lower end of the fixed ruler 1 can be extruded into the mounting hole 5 at the moment, the probe 7 is in contact with the surface of the glass, the probe 7 at the moment can drive the measuring head 202 and the measuring rod 201 to move upwards, a first numerical value can appear on the display screen of the electronic dial indicator 2 at the moment, then the detection person pushes the fixed ruler 1 along the surface of the glass, so that the fixed ruler 1 slides on the surface of the glass, and if the surface of the glass is flat enough, the number on the display screen of the electronic dial indicator 2 does not change and is the same as the first numerical value;

if the glass surface is not flat, because the downside of fixed ruler 1 is straight all the time, the gap will appear between the downside edge of fixed ruler 1 and the glass like this, probe 7 at this moment under spring 8's effect, also can appear small removal downwards, probe 7 will drive gauge head 202 and measuring staff 201 and move downwards, the figure on the display screen of electronic percentage table 2 at this moment changes, the second numerical value appears, the change of notice numerical value, just can obtain the change of glass surface crookedness, through subtracting little numerical value with big numerical value, just can obtain the numerical value of crookedness.

When installing electronic percentage table 2, with the vertical installation of gauge rod 201 and gauge head 202 in the inside of mounting groove 3, then through putting into second screw 403 in fixed orifices 401, align second screw 403 with second screw 402 the back, screw up fixedly for gauge rod 201 is tightly fixed inside mounting groove 3.

When the probe 7 and the measuring head 202 are installed, the measuring head 202 is inserted into the groove 9, then the first screw 11 is placed into the first screw hole 10, the first screw 11 is tightly fixed on the measuring head 202 after being screwed, and the rubber pad enables the combination to be more tight.

If the electronic dial indicator 2 is damaged or the precision is not high, when the electronic dial indicator 2 needs to be maintained, the electronic dial indicator 2 can be conveniently detached from the fixed ruler 1, and the whole electronic dial indicator 2 can be taken out from the fixed ruler 1 only by taking the first screw 11 and the second screw 403 down.
