Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
The jig 100 for detecting parallelism of a sample according to an embodiment of the present application is described below with reference to the drawings. Wherein, the test sample may include a first plate 200 and a second plate 300. The jig 100 may be used to detect whether the first board body 200 and the second board body 300 are parallel. For example, the sample to be tested may be the template of a glass hot bender. That is, the jig 100 of the present application can be used to detect the parallelism of the pattern plates of a glass hot bending machine. Specifically, the pattern plate includes an upper pattern plate (i.e., the first plate body 200) and a lower pattern plate (i.e., the second plate body 300), and the jig 100 may detect whether the upper pattern plate and the lower pattern plate are parallel. Of course, the sample to be detected is not limited to this, and may be other objects requiring parallelism detection.
The jig 100 for detecting the parallelism of the sample according to the embodiment of the first aspect of the present application includes a positioning block 1, and a bottom surface of the positioning block 1 has a first reference surface. The positioning block 1 is provided with a plurality of grooves 11 with open tops. Here, it should be noted that "a plurality" in the present application means three or more, that is, at least three.
The support piece 2 and the height column 3 are arranged in each groove 11, the support piece 2 is arranged on the bottom wall of each groove 11, the height column 3 is supported on the support piece 2, the support piece 2 can be subjected to plastic deformation under the detection condition, the upper surfaces of the height columns 3 in all the grooves 11 are located in a second reference surface under the initial state of the support piece 2, and the second reference surface is parallel to the first reference surface.
In the present application, "plastic deformation is allowed" is to be broadly understood as long as the capability of plastic deformation (self-unrecoverable deformation) under the detection condition is provided. For example, glass is a brittle material at normal temperature, but glass can soften and collapse at high temperatures, and therefore glass has the ability to plastically deform at high temperatures. Thus, when the detection condition is a high temperature condition, the support member 2 may be a glass member. The "initial state" refers to a state in which the support member 2 is not plastically deformed.
In the initial configuration of the support 2, the line between the geometric centers of gravity of the upper surfaces of the plurality of height posts 3 is formed as a polygon. For example, when the number of the grooves 11 is three, the geometric centers of gravity of the upper surfaces of the height posts 3 in the three grooves 11 may enclose a triangle, and when the number of the grooves 11 is four, the geometric centers of gravity of the upper surfaces of the height posts 3 in the four grooves 11 may enclose a square or a rectangle. That is, in the initial configuration of the support 2, the geometric centers of gravity of the upper surfaces of the plurality of height posts 3 are not collinear. Thereby, a second reference surface may be defined by the upper surfaces of the plurality of height posts 3. The geometric center of gravity refers to a mathematical center of gravity, for example, the intersection point of three central lines of a triangle is the geometric center of gravity of the triangle.
When the jig 100 is used to detect the parallelism of a sample, the jig 100 may be interposed between the first plate 200 and the second plate 300 of the sample. For example, referring to fig. 7 and 8, the first plate 200 and the second plate 300 are spaced up and down, the second plate 300 may be attached to the first reference surface, and the first plate 200 may be disposed above the height post 3. During detection, the first plate body 200 may be pressed down to deform the support member 2 (for example, the support member 2 may be flattened), and then whether the first plate body 200 and the second plate body 300 are parallel or not may be determined by measuring the height difference of the plurality of height columns 3, and the position of the first plate body 200 may be adjusted by the measured height difference to make the first plate body 200 and the second plate body 300 parallel, so as to correct the parallelism of the sample.
In some embodiments of the present application, the distance between the upper surface of each height post 3 and the first reference surface may be measured to calculate the height difference of the height posts 3. For example, the height difference of the height columns 3 may be obtained by measuring the distance between the upper surface of each height column 3 and the first reference surface using a height gauge, whereby the accuracy of detection may be improved.
According to tool 100 for detecting sample depth of parallelism of this application embodiment, through set up recess 11 on locating piece 1, and set up high post 3 and can take place plastic deformation's support piece 2 under the detection condition in recess 11, from this, under the detection condition (for example under appropriate temperature), can make support piece 2 take place to warp through pushing down high post 3, and then can be through measuring support piece 2 deformation back, the depth of parallelism of sample is detected and rectified to the difference in height of a plurality of high posts 3, tool 100's simple structure and testing process are simple and convenient easy to operate, the time of detecting the sample depth of parallelism has greatly been shortened, detection efficiency is improved, and the detection degree of difficulty has been reduced.
According to some embodiments of the present application, the positioning block 1 is provided with a plurality of through channels 12, the plurality of through channels 12 correspond to the plurality of grooves 11 one-to-one, one end of each through channel 12 (for example, the upper end of the through channel 12 in fig. 4) extends to the bottom wall of the corresponding through groove 11 to form a first communication port 121, and the other end of each through channel 12 (for example, the lower end of the through channel 12 in fig. 4) extends to the bottom surface of the positioning block 1 to form a second communication port 122. Therefore, after the parallelism of the sample is detected, the deformed support piece 2 can be ejected out through the through channel 12 by means of a tool, so that the support piece 2 is separated from the bottom wall of the groove 11, the support piece 2 can be conveniently taken out, and the jig 100 can be conveniently reused.
Optionally, the through channel 12 extends in a vertical direction. Thereby, the resistance of the tool to passing through the through passage 12 can be reduced, facilitating the tool to pass out of the first communication port 121 to eject the support member 2.
According to some embodiments of the present application, the support 2 is formed in an initial state in a spherical, ellipsoidal, cylindrical, rectangular parallelepiped, square or irregular shape. Therefore, the support piece 2 is easy to be flattened and deformed, and has a simple structure and convenient processing.
According to some embodiments of the present application, a portion of the orthographic projection of the support 2 on the bottom wall of the recess 11 covers the first communication opening 121. That is, the area of the orthographic projection of the support member 2 on the bottom wall is larger than the sectional area of the first communication port 121. Therefore, the support member 2 can be prevented from completely falling into the through channel 12, and the accuracy of the detection result of the jig 100 is ensured. At the same time, after the deformation of the support 2, it is ensured that the first communication opening 121 is covered by the support 2, thereby facilitating the ejection of the deformed support 2 by a tool through the through passage 12.
According to some embodiments of the application, the first reference plane extends in a horizontal direction. It will be appreciated that a part of the bottom surface of the positioning block 1 may be configured as the first reference surface, and the entire bottom surface of the positioning block 1 may be configured as the first reference surface.
In the detection process, when the first plate 200 is pressed down, in order to ensure the accuracy of the detection result, an external force extending along the normal line of the first plate 200 may be applied to the first plate 200. The first reference surface is set to be a plane extending in the horizontal direction, and an external force extending in the vertical direction may be applied to the first plate body 200 at the time of detection. Therefore, the direction of the external force can be conveniently controlled, and the accuracy of the detection result is improved.

In some embodiments of the present application, the positioning block 1 is a mold steel piece or a graphite piece. The structural strength of the die steel is high, the material cost is low, the positioning block 1 is set to be a die steel piece, the structural strength of the positioning block 1 can be improved, and the material cost is reduced. The graphite has good high-temperature resistance, and the positioning block 1 is set as a graphite piece, so that the applicable temperature range of the positioning block 1 can be enlarged, and the application range of the jig 100 can be enlarged.
In some embodiments of the present application, the height post 3 is a piece of mold steel or graphite. The structural strength of the die steel is high, the material cost is low, the height column 3 is set to be a die steel piece, the structural strength of the height column 3 can be improved, and the material cost is reduced. The graphite has good high temperature resistance, and the height column 3 is set as a graphite piece, so that the applicable temperature range of the height column 3 can be enlarged, and the application range of the jig 100 can be enlarged.
According to some embodiments of the present application, the support 2 is a plasticine, plastic, metal or glass piece. Wherein the plasticine and the plastic can generate plastic deformation under the action of external force at normal temperature. Metals and glass can be plastically deformed at high temperatures under the action of external forces. The user can select the material of the supporting member 2 according to the detection condition of the jig 100.
According to the method for detecting the parallelism of the sample, which is provided by the embodiment of the second aspect of the present application, the sample comprises the first plate body 200 and the second plate body 300, and the method for detecting the parallelism of the sample comprises the following steps:
s10: moving down the first plate 200 to make the first plate 200 contact with the upper surface of the height post 3;
s20: pressing down the first plate 200 plastically deforms the support member 2;
s30: the height difference of the height posts 3 is measured.
Specifically, during the detection process, the first board 200 may be gradually moved downward, and when the first board 200 contacts with the upper surface of the height post 3, the first board 200 is pressed downward, and the supporting post is gradually flattened along with the gradual movement downward of the first board 200. And then the parallelism of the sample can be judged by measuring the height difference of the height column 3. In some embodiments of the present application, the distance between the upper surface of each height post 3 and the first reference surface may be measured to calculate the height difference of the height posts 3.
The whole detection process can be carried out at normal temperature or high temperature. For example, in the actual detection process, the actual use environment of the sample can be simulated, and the parallelism of the sample can be detected. Therefore, detection errors can be reduced, and the accuracy of detection results can be improved.
