a UA3P positioning and measuring table is used for measuring a glass mold and comprises a limiting table body, a positioning hole for positioning the limiting table body and a limiting edge; the limiting edge is used for positioning a processing jig of the glass mold and is arranged on the top edge of the limiting table body. In this scheme, changed the mode of measuring alone the mould, realized keeping the mould to measure in processing tool, when can quick center location, avoided the problem of many times tool setting.

Preferably, the cross section of the limiting table body is an axisymmetric figure.

Preferably, the limiting table body is of a boss structure, and the positioning holes are formed in two sides of the boss structure. The boss structure is used for heightening the measuring table, and the height can be determined according to the height of an object to be measured, so that the distance between the object to be measured and the probe balance point is shortened.

Preferably, the limiting table body is of a square boss structure, the limiting edges are three limiting edges which are respectively arranged on the three edges of the square boss structure and used for positioning the glass processing jig from three directions, and one direction which is not limited is the starting moving direction for pushing the glass processing jig.

Preferably, in order to realize light weight, the boss structure is a hollow shell, and the requirement of UA3P as an ultrahigh-precision measuring instrument on the weight of the placing table is met.

Preferably, the number of the positioning holes is two, and the two positioning holes are symmetrically arranged on the boss structure.

Preferably, the material of the positioning and measuring table is stainless steel.

Preferably, the measuring center of the UA3P is located on the symmetry axis of the axisymmetric pattern, so that the measuring center and the center of the object to be measured can coincide more quickly.

Compared with the prior art, one or more of the technical schemes can achieve at least one of the following beneficial effects:

this location survey table can be rapidly with determinand center and measurement center coincidence, the convenient location of measuring for the determinand need not take off from the processing tool completely, avoids tool setting once more, shortens process time, has improved greatly and has measured and mended machining efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, the present embodiment provides a UA3P positioning measuring station. The positioning and measuring table is used for measuring a glass mold, and as a specific implementation manner, the present embodiment takes the mold core measurement of the glass mold as an example.

The positioning and measuring table comprises a limiting table body 2, a positioning hole 1 for positioning the limiting table body 2 and a limiting edge 3. The limiting edge is used for positioning a processing jig of the glass mold and is arranged on the top edge of the limiting table body.

The cross section of the limiting table body 2 is an axisymmetric figure, and the measuring center of the UA3P is positioned on the symmetric axis of the axisymmetric figure. In a preferred embodiment, the limiting table body 2 is a square boss structure, and the top surface of the limiting table body is square. The height of the position-limiting table body 2 of the present embodiment is 5mm.

The positioning holes 1 are arranged on two sides of the boss structure. More specifically, the locating hole is two, and the symmetry sets up in the both sides edge of boss structure. The positioning hole 1 avoids the convex part of the boss structure.

The design of the boss structure reduces the volume and the weight while shortening the distance between the object to be detected and the probe balance point of the UA3P.

The limiting edges 3 are three limiting edges and are respectively arranged on the three square edges to limit the three directions.

The boss structure in this embodiment is a hollow housing to further achieve light weight.

In this embodiment, the positioning and measuring table is made of stainless steel.

The working principle of the embodiment is as follows:

the UA3P positioning and measuring table is placed on the UA3P placing table, the measuring center of the UA3P is located on a symmetry axis of the cross section of the positioning and measuring table, and the measuring table is fixed by a screw penetrating through the positioning hole 1. After the ultra-precise aspheric surface processing equipment processes the mold core, the mold core in the processing jig sucker does not need to be taken down, the sucker with the mold core is directly pushed to the limiting edge from the position of the limiting edge 3 which is not enclosed until the sucker is contacted with the limiting edges in three directions, namely, the sucker is limited to a position, so that the center of the sucker is coincided with the measuring center, and the mold core to be measured is coincided with the measuring center. After measurement, if correction processing is needed, the sucker with the mold insert is loaded into the ultra-precise aspheric surface processing equipment without re-aligning the tool.

The location survey meter of this embodiment design can match the current platform of placing of UA3P, need not to carry out the major change to current, will fix a position the survey meter and place the platform in can. The center of the object to be measured can be rapidly coincided with the measuring center, the problem of repeated tool setting caused by completely taking down the mold core from the jig in the prior art is solved, and the device has the advantages of small size, light weight, low cost and detachability.

It should be understood that the above-mentioned embodiments are only examples for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection of the claims of the present invention.
