Referring to fig. 1, 2 and 3, the embodiment of the present disclosure provides a measuring device including a fixing member 20 and a measuring member 10. Along the first direction, the fixing part 20 and the measuring part 10 are oppositely arranged, the measuring part 10 comprises a first seat body 11 and a plurality of propping heads 12, the first seat body 11 is provided with a plurality of through holes 113, and the propping heads 12 penetrate through the through holes 113 in a one-to-one correspondence manner.

The measuring device of the embodiment of the disclosure can be used for measuring the arc-shaped glass 30, wherein the middle part of the arc-shaped glass 30 is a plane, and at least one side of the edge of the arc-shaped glass is an arc surface.

The fixing member 20 is used to fix the curved glass 30.

The first direction may be a direction shown by a Z-axis in the drawing, and the first direction may also be a vertical direction.

The abutting head 12 is arranged through the through hole 113 in a penetrating way, so that the abutting head 12 is movably connected to the first seat body 11, and the abutting head 12 and the through hole 113 can be in sliding fit.

The first housing 11 may be movable in a first direction such that a distance between the abutment head 12 and the arc glass 30 can be adjusted, and in particular, the measuring device may further include a cylinder or a rail, a fixed end of the cylinder being connected to the fixing member 20, and a telescopic end of the cylinder being connected to the first housing 11 such that the first housing 11 can be movable in the first direction. The guide rail may be provided to the fixing member 20 and extend in the first direction, and the first housing 11 may be slidably coupled to the guide rail.

The measuring part 10 is used for measuring the arc-shaped glass 30, specifically, in the initial state, the positions of the abutment heads 12 relative to the first housing 11 may be uniform, such as the distances between the sides of the plurality of abutment heads 12 away from the fixing part 20 and the sides of the first housing 11 away from the fixing part 20 may be uniform. The first seat 11 is moved in the first direction until the abutting heads 12 abut against the surface of the arc glass 30, and the first seat 11 is further moved, because the surface flatness of the arc glass 30 is different, so that the positions of the plurality of abutting heads 12 relative to the first seat 11 are also different, by measuring the position change of the abutting heads 12 relative to the first seat 11, on the one hand, the flatness of the arc glass 30 can be measured, for example, in the plurality of abutting heads 12 corresponding to the measured flatness, if the position change of all the abutting heads 12 relative to the first seat 11 is consistent, the flatness of the arc glass 30 meets the requirement, and if the position change of part of the abutting heads 12 relative to the first seat 11 is different from the other abutting heads 12, the flatness of the arc glass 30 does not meet the requirement. On the other hand, the arc height of the arc-shaped part of the arc-shaped glass 30 can be measured, namely, the moving distance of the abutting head 12 corresponding to the measured arc height relative to the first seat body 11 is the arc height of the contact part of the abutting head 12 and the arc-shaped part.

Under the action of the measuring part 10, flatness measurement of the arc glass 30 and arc height measurement of the arc portion of the arc glass 30 can be simultaneously performed, and measurement efficiency is improved.

The first abutment head 121 is in a straight shape at one end near the fixing member 20 so that the first abutment head 121 can measure the arc height of the highest point of the arc-shaped portion of the arc-shaped glass 30. The contact between the dial indicator and the workpiece is point-surface contact, so that the arc height of the highest point of the arc part can be measured only if the spherical head of the dial indicator is aligned with the highest point of the arc part, and the projection of the arc part on the straight-line end of the first abutting head 121 is ensured to be in the range of the straight-line end only when the first abutting head 121 is in operation.

cold forging the end of the first abutment head 121 to form a flat shape;

cutting and trimming the flat end of the first abutment head 121;

the flat end of the first abutment head 121 is polished smooth.

By the method, the first abutting head 121 can form a linear structure, materials are saved, compared with the fact that the linear end obtained by directly cutting the first abutting head 121 into a flat shape is longer, the longer the linear end of the first abutting head 121 is, the easier the projection of the arc-shaped part on the linear end of the first abutting head 121 falls into the range of the linear end, adjustment of the position of the arc-shaped glass 30 during arc height measurement is reduced, and measurement efficiency is improved.

The pointed end of the second abutment head 122 may be formed by machining:

a plurality of grooves are cut in the second abutment head 122 around the circumference of the second abutment head 122, the grooves extending in the axial direction of the second abutment head 122 to the tip of the second abutment head 122, and the depth of the grooves being greater nearer to the tip of the second abutment head 122 in the axial direction of the second abutment head 122, the plurality of grooves being disposed around the circumference of the second abutment head 122.

And (3) polishing the side walls between the adjacent grooves, and reducing the height of the side walls.
