Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the application.
A 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 and second plates 200 and 300 are parallel. For example, the sample to be tested may be a template of a glass heat bender. That is, the jig 100 of the present application may be used to detect parallelism of a template of a glass heat bender. Specifically, the jig 100 may detect whether the upper and lower templates (i.e., the first and second plate bodies 200 and 300) are parallel. Of course, the sample to be detected is not limited thereto, and may be other objects requiring parallelism detection.
The jig 100 for detecting parallelism of a sample according to the embodiment of the first aspect of the application includes a positioning block 1, wherein 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, "a plurality of" in the present application means three or more, that is, at least three.
Each groove 11 is internally provided with a support 2 and a height column 3, the support 2 is arranged on the bottom wall of the groove 11, the height column 3 is supported on the support 2, under the detection condition, the support 2 can be plastically deformed, and in the initial form of the support 2, the upper surfaces of the height columns 3 in all the grooves 11 are positioned in a second reference plane, and the second reference plane is parallel to the first reference plane.
In the present application, "plastic deformation" is to be understood in a broad sense as long as it has the ability to undergo plastic deformation (deformation that is not self-restorable) under the detection conditions. For example, glass is a brittle material at normal temperature, but glass can soften and collapse at high temperature, and therefore, glass has a plastic deformation capability at high temperature. Thus, when the detection condition is a high temperature condition, the support 2 may be a glass member. The "initial state" refers to a state when the support 2 is not plastically deformed.
In the initial form 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 grooves 11 are 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 grooves 11 are 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 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 plane may be defined by the upper surfaces of the plurality of height posts 3. Wherein the geometric center of gravity refers to the mathematical center of gravity, e.g., the intersection of the three centerlines of the triangle is the geometric center of gravity of the triangle.
When the jig 100 is used to detect parallelism of a sample, the jig 100 may be sandwiched between the first and second plates 200 and 300 of the sample. For example, referring to fig. 7 and 8, the first plate 200 and the second plate 300 are disposed at an upper and lower interval, the second plate 300 may be attached to the first reference surface, and the first plate 200 may be disposed above the elevation column 3. In the detection process, the first plate 200 can be pressed down to deform the supporting member 2 (for example, the supporting member 2 can be flattened), then the height difference of the plurality of height posts 3 is measured to determine whether the first plate 200 and the second plate 300 are parallel, and the position of the first plate 200 can be adjusted through the measured height difference to enable the first plate 200 and the second plate 300 to be parallel, so that the parallelism of the sample is corrected.
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 posts 3 may be obtained by measuring the distance between the upper surface of each height post 3 and the first reference surface using a height gauge, whereby the accuracy of detection may be improved.
According to the jig 100 for detecting parallelism of a sample, according to the embodiment of the application, the groove 11 is formed in the positioning block 1, the height column 3 and the support 2 which can be plastically deformed under the detection condition are arranged in the groove 11, so that the support 2 can be deformed under the detection condition (for example, at a proper temperature) by pressing down the height column 3, and then the parallelism of the sample can be detected and corrected by measuring the height difference of the plurality of height columns 3 after the support 2 is deformed, the structure of the jig 100 is simple, the detection process is simple and easy to operate, the time for detecting the parallelism of the sample is greatly shortened, the detection efficiency is improved, and the detection difficulty is reduced.
According to some embodiments of the present application, the positioning block 1 is provided with a plurality of through channels 12, the through channels 12 are in one-to-one correspondence with the grooves 11, one end of the through channel 12 (for example, an upper end of the through channel 12 in fig. 4) extends to a bottom wall of the through groove 11 to form a first communication opening 121, and the other end of the through channel 12 (for example, a lower end of the through channel 12 in fig. 4) extends to a bottom surface of the through positioning block 1 to form a second communication opening 122. Therefore, after the parallelism of the sample is detected, the deformed support piece 2 can be ejected out by means of a tool through the through channel 12, so that the support piece 2 is separated from the bottom wall of the groove 11, and the support piece 2 can be conveniently taken out, thereby being convenient for reusing the jig 100.
Alternatively, the through passage 12 extends in the vertical direction. Thereby, the resistance of the tool passing through the through passage 12 can be reduced, facilitating the tool to pass out from the first communication port 121 to jack up the support 2.
According to some embodiments of the present application, the support 2 is formed in an initial state in a spherical, ellipsoidal, cylindrical, rectangular, square or irregular shape. Thus, the supporting piece 2 is easy to be flattened and deformed, and has simple structure and convenient processing.
According to some embodiments of the application, a portion of the orthographic projection of the support 2 on the bottom wall of the recess 11 is overlaid on 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 piece 2 can be prevented from falling into the through channel 12 completely, and the accuracy of the detection result of the jig 100 is ensured. Meanwhile, after the support member 2 is deformed, it is ensured that the first communication port 121 is covered by the support member 2, thereby facilitating the ejection of the deformed support member 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 portion of the bottom surface of the positioning block 1 may be configured as the first reference surface, or the entire bottom surface of the positioning block 1 may be configured as the first reference surface.
In the inspection process, when the first plate 200 is pressed down, an external force extending along the normal line of the first plate 200 may be applied to the first plate 200 in order to ensure the accuracy of the inspection result. The first reference surface is provided as 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 is convenient to control, and the accuracy of the detection result is improved.
In some embodiments of the present application, the positioning block 1 is formed in a square or rectangular parallelepiped shape. Simple structure and convenient processing.
In some embodiments of the application, the positioning block 1 is a die steel piece or a graphite piece. The die steel has high structural strength and low material cost, and the positioning block 1 is arranged as a die steel piece, so that 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 arranged 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 application, the height column 3 is a die steel piece or a graphite piece. The die steel has high structural strength and low material cost, and the height column 3 is arranged as a die steel part, so that the structural strength of the height column 3 can be improved, and the material cost is reduced. The high temperature resistance of graphite is good, and the height column 3 is set to be 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 application, the support 2 is a plasticine, plastic, metal or glass piece. Wherein, the plasticine and the plastic can be plastically deformed under the action of external force at normal temperature. Metals and glass can undergo plastic deformation under the influence of external forces at high temperatures. The user can reasonably select the material of the supporting member 2 according to the detection condition of the jig 100.
According to the method for detecting parallelism of a sample according to the embodiment of the second aspect of the present application, the sample includes a first plate 200 and a second plate 300, and the method for detecting parallelism of the sample includes the steps of:
s10: moving the first plate 200 downward to bring the first plate 200 into contact with the upper surface of the elevation column 3;
s20: depressing the first plate 200 to plastically deform the support 2;
s30: the difference in height of the height column 3 is measured.
Specifically, during the detection process, the first plate 200 may be gradually moved down, and when the first plate 200 contacts the upper surface of the height column 3, the first plate 200 is pressed down, and the support column will be gradually flattened as the first plate 200 gradually moves down. 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 at 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, the detection error can be reduced, and the accuracy of the detection result can be improved.
It will be appreciated that when the actual environment of use of the sample is at a high temperature, the sample parallelism can be measured at normal temperature as well. Therefore, the detection difficulty can be reduced, the detection efficiency is improved, and the detection time consumption is shortened.
According to the method for detecting the parallelism of the sample, the groove 11 is formed in the positioning block 1, the height column 3 and the supporting piece 2 which can be subjected to plastic deformation under the detection condition are arranged in the groove 11, so that the supporting piece 2 can be deformed by pressing down the height column 3, the parallelism of the sample can be detected and corrected by measuring the height difference of the plurality of height columns 3 after the supporting piece 2 is deformed, the structure of the jig 100 is simple, the detection process is simple and convenient, the operation is easy, the time for detecting the parallelism of the sample is greatly shortened, the detection efficiency is improved, and the detection difficulty is reduced.

s40: the position of the first plate 200 is adjusted according to the height difference so that the first plate 200 is parallel to the second plate 300. Therefore, the parallelism of the sample can be conveniently and rapidly corrected.
According to some embodiments of the application, in step S30, the difference in height of the height column 3 is measured using a height gauge. Thereby, the accuracy of detection can be improved.
According to some embodiments of the present application, the first plate 200 is provided with a plurality of fixing holes, where the plurality of fixing holes are in one-to-one correspondence with the plurality of height columns 3, and in step S10, at least a portion of the central axes of the fixing holes are coincident with the central axes of the height columns 3 corresponding thereto. Wherein, the fixing hole can be penetrated with a fixing member, and the first plate 200 is fixed on the device with the sample through the fixing member.
Specifically, the central axes of some of the fixing holes may coincide with the central axes of the height posts 3 corresponding thereto, or the central axes of all of the fixing holes may coincide with the central axes of the height posts 3 corresponding thereto. Therefore, after the height difference of the height column 3 is measured, the fixing piece in the fixing hole can be adjusted according to the height condition of the height column 3 corresponding to the fixing hole so as to adjust the position of the first plate body 200, so that the first plate body 200 is parallel to the second plate body 300, the accuracy of correcting the parallelism of the sample is improved, the parallelism of the correction sample is reduced, the correction efficiency is improved, and the correction time is further shortened.
