The squarer is a device for cutting parts into squares, is commonly used for cutting silicon rods of solar single crystals, and is provided with two disc sheets on a main roller 400, wherein each disc sheet is provided with a plurality of grooves. In an actual processing process, the processed main roller 400 cannot meet a preset precision requirement. Specifically, the old coating layer needs to be removed and the new coating layer needs to be coated in the machining process by using a lathe, but the disc of the main roller 400 is not protected in the machining process by using the lathe, so that the disc is damaged, that is, the size of the disc, such as the width and the diameter, is correspondingly reduced. This results in the need to use associated tools to check whether the main roller 400 is coplanar with the idler 500 during subsequent processing. When the main roller 400 and the guide wheel 500 are not coplanar, a large amount of grooves are abraded, the service life of the grooves is directly affected, and the margin of the cut silicon rod is unstable.

In the prior art, in order to control the lower limit of the margin of the cut silicon rod and prolong the service life of the main roller 400, the size of the groove needs to be increased, but this increases the processing allowance of the silicon rod, increases the loss of the silicon rod, and increases the production cost.

In view of the above technical problem, an embodiment of the present invention provides a measuring tool. Fig. 1 illustrates a schematic structural diagram of a measurement tool provided in an embodiment of the present invention, and fig. 2 illustrates a usage state diagram of the measurement tool provided in the embodiment of the present invention. Referring to fig. 1, a measurement tool provided in an embodiment of the present invention includes: main scale 100, positioning scale 200 and measuring scale 300. The positioning rule 200 is fixed to one end of the main rule 100, and the positioning rule 200 is perpendicular to the main rule 100 and symmetrically extends toward both sides of the main rule 100. The measuring scale 300 is slidably disposed on the main scale 100, the measuring scale 300 and the positioning scale 200 are disposed on the same side of the main scale 100, and the scales on the measuring scale 300 correspond to the scales on the positioning scale 200 one by one.

Referring to fig. 2, the present invention provides a measuring tool for coplanar inspection of a main roller 400 and a guide wheel 500 during cutting in a squarer, compared to the prior art. The measuring scale 300 is slidably disposed on the main scale 100, and can be adapted to the main roller 400 and the guide wheel 500 with different pitches.

Whether the main roller 400 and the guide wheel 500 are in a coplanar state or not can be judged quickly and accurately according to the sizes of the first distance and the second distance. Specifically, when the first distance is different from the second distance, there is an offset angle between idler 500 and main roller 400, that is: main roller 400 and idler 500 are not coplanar. At this time, the position of guide wheel 500 may be adjusted until main roller 400 is in a coplanar state with guide wheel 500. The measuring tool provided by the utility model has a simple structure, can quickly and accurately measure whether the main roller 400 and the guide wheel 500 are coplanar, avoids the phenomenon of uneven grinding of the groove on the main roller 400 in the process of cutting the silicon rod, and further can stabilize the edge distance of the processed square silicon rod.

The measuring scale 300 is parallel to the positioning scale 200, and can accurately determine whether the first distance is equal to the second distance.

In one possible implementation, referring to fig. 1, the positioning ruler 200 and the measuring ruler 300 are located in the same plane. In the actual use process, when the positioning ruler 200 and the measuring ruler 300 are located on the same plane on the same side, whether the main roller 400 and the guide wheel 500 are coplanar can be judged more conveniently and accurately.

In a possible implementation manner, the scales on the positioning rule 200 are distributed in a direction perpendicular to the extending direction of the main rule 100. As described above, the extending direction of the positioning rule 200 is perpendicular to the extending direction of the main rule 100. The scale distribution direction on the positioning rule 200 can be set along the edge of the positioning rule 200.

In one possible implementation, the unit scale of the positioning ruler 200 is the same as the unit scale of the measuring ruler 300. The unit scale of the positioning rule 200 is the same as that of the measuring rule 300 to quickly and clearly determine whether the first distance and the second distance are equal.

In a possible implementation, the main scale 100 has a scale provided along the extending direction of the main scale 100. The scale on main scale 100 may facilitate confirmation of the distance between main roller 400 and idler 500.

The scale 301, the positioning ruler 200 and the main ruler 100 may be made of the same material, or different materials may be used.

The scale on the scale 301 may be a concave portion or a convex portion formed on the scale 301. Of course, the scale on the scale 301 may be a scale printed on the scale 301, but is not limited thereto. The form of the scale may be selected according to the actual conditions such as the material of the scale 301, and the embodiment of the present invention is not particularly limited.

Based on fixing the measuring scale 300 on the main scale 100, it is possible to prevent the measuring scale 300 from shaking along the main scale 100 in the process of performing the coplanar measurement on the main roller 400 and the guide wheel 500, thereby affecting the accuracy of the measurement result.

In a possible implementation manner, the measuring tool may further include a limiting member.

In practical applications, the stopper is provided at the other end of the main scale 100 with respect to the positioning scale 200, and is used to limit the sliding range of the measuring scale 300 and prevent the measuring scale 300 from being separated from the main scale 100 during the sliding process. In one example, the stopper may be mounted on an end of the main scale 100 by a fastener such as a bolt or a screw, and when it is necessary to separate the measuring scale 300 from the main scale 100, the stopper may be removed from the main scale 100, so that the measuring scale 300 is separated from the main scale 100.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
