DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] As shown in Figure 1 and Figure 2 , a verticality detector for positioning L-shaped plate, comprising air floating guide rail 1 and air floating platform 2, air floating platform 2 is connected on air floating guide rail 1, both ends of air floating guide rail 1 are connected with baffle 3, opposite sides of baffle 3 are connected with L-shaped positioning plate 4, one side of L-shaped positioning plate 4 is provided with laser level 9, laser level 9 is connected on air floating guide rail 1; horizontal reference can be provided by laser level 9, which can assist in determining that L-shaped positioning plate 4 is installed in horizontal direction, so as to avoid measurement error caused by poor parallelism. The bottom of L-shaped positioning plate 4 is connected with first distance measuring sensor 5; first distance measuring sensor 5 measures the distance of workpiece placed on air floating platform 2, so as to ensure the verticality of workpiece and horizontal reference.

[0032] As shown in Figure 3 and Figure 4As shown, a positioning plate 6 is connected to the air-float platform 2, and a measuring bracket 11 is connected to the positioning plate 6. The measuring bracket 11 is U-shaped and is perpendicular to the positioning plate 6. A second distance sensor 7 is connected to the top inner side of the measuring bracket 11. The positioning plate 6 is detachably connected to the air-float platform 2. The measuring bracket 11 is connected to the positioning plate 6 via a lifting block 10, which slides longitudinally with the positioning plate 6. The workpiece whose verticality needs to be tested is then placed on the L-shaped positioning plate 4 of the air-float platform 2. The L-shaped positioning plate 4 provides initial positioning of the workpiece. Then, based on the actual dimensions of the workpiece, the height of the measuring bracket 11 is changed by adjusting the lifting block 10 to slide longitudinally along the positioning plate 6, thereby ensuring that the inner bottom side of the measuring bracket 11 is in contact with the workpiece. The measuring bracket 11 includes a lower component 12, a connecting component 13, and an upper component 14. The lower component 12 is connected to the lifting block 10, and the upper component 14 is connected to the lower component 12 via the connecting component 13. Both the lower component 12 and the upper component 14 are slidably connected to the connecting component 13.

The upper component 14 is slidably connected to the connecting component 13, and the positioning bolts 15 fix the position of the upper component 14, placing the second distance sensor 7 on the measuring bracket 11 at a suitable height. The air-floating platform 2 is then slidably connected to the air-floating guide rail 1, causing the air-floating platform 2 to drive the second distance sensor 7 to measure the distance to the corresponding position on the workpiece, obtaining the distance value between the workpiece and the position of the measuring bracket 11 in the vertical direction. The distance data measured by the first distance sensor 5 and the second distance sensor 7 are then transmitted to a connected data processing system for analysis and processing, ultimately yielding the overall verticality detection result of the workpiece. An anti-friction pad 16 is connected to the inner bottom of the lower component 12. This can prevent the workpiece being tested from contacting the lower component 12, reduce friction, avoid scratching the workpiece being tested, and also reduce wear on the lower component 12, which is conducive to the long-term stable use of the instrument and maintaining measurement accuracy.

Both the first distance measuring sensor 5 and the air-bearing guide rail 1 use the air-bearing guide rail 1 as the reference surface, and the flatness of the surface of the air-bearing guide rail 1 is less than 0.01mm. This provides a precise reference surface for subsequent measurements, reduces measurement errors, and makes the measurement results more accurate. At the same time, the air-bearing platform 2 can smoothly slide and connect to the air-bearing guide rail 1.

[0034] The working process of this utility model is as follows:

[0035] Firstly, the workpiece to be detected for perpendicularity is placed on the L-shaped positioning plate 4 of the air floating platform 2, the workpiece is preliminarily positioned through the L-shaped positioning plate 4, then the height position of the measuring support 11 is changed by adjusting the lifting block 10 to slide along the positioning plate 6 according to the actual situation such as the size of the workpiece, then the bottom inner side of the measuring support 11 is attached to the workpiece, then the upper assembly 14 is slidingly connected with the connecting assembly 13, then the positioning bolt 15 fixes the position of the upper assembly 14, so that the second distance measuring sensor 7 on the measuring support 11 is at a suitable height, then the air floating platform 2 is slidingly connected on the air floating guide rail 1, then the air floating platform 2 drives the second distance measuring sensor 7 to measure the distance of the corresponding position on the workpiece, and the distance value of the workpiece in the vertical direction to the position where the measuring support 11 is located is obtained.

[0036] Meanwhile, the first distance measuring sensor 5 at the bottom of the L-shaped positioning plate 4 measures the distance of the workpiece placed on the air floating platform 2, so as to ensure the perpendicularity of the workpiece to the horizontal reference. Then the distance data measured by the first distance measuring sensor 5 and the second distance measuring sensor 7 is transmitted to the data processing system connected therewith, then the data is analyzed and processed, and finally the perpendicularity detection result of the whole workpiece is obtained.
