Description

Technical Field

[0001] The utility model belongs to the technical field of metallographic inspection, and particularly relates to a leveling jig for a slicing observation surface. Background Art

[0002] When conducting incoming inspection on FPC / PCB and product failure analysis, a large number of metallographic slices need to be made for observation and analysis of the cut surface. The slicing grinding process mostly uses manual grinding, which cannot ensure uniform force, resulting in non-parallel upper and lower surfaces of the slice. During metallographic observation, the cut surface is inclined with respect to the microscope lens surface, and the metallographic image appears clear on one side and blurred on the other side, so that the entire sample cannot be observed simultaneously. In the process of preparing metallographic slices by most engineers and technicians, the above situation will occur. To make the entire metallographic image clear, the main current solution is to place a piece of paper under the metallographic slice and adjust the metallographic slice to make its surface as parallel as possible to the microscope lens surface before the metallographic image can be adjusted clearly. However, during the process of leveling with a piece of paper, it is necessary to repeatedly debug until the observation surface of the sample is flat, resulting in an extended test time and reduced experimental efficiency. How to quickly level the cut surface to improve the efficiency of metallographic slice analysis is an urgent problem in this field. Summary of the Utility Model

[0006] Specifically, the plurality of threaded holes are evenly distributed in the circumferential direction of the fixing seat.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] The terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more than two.

[0021] Referring to Figures 1-3 , the present utility model provides a leveling jig for a sliced observation surface, which includes a leveling member 1 and a fixed seat 2; the leveling member 1 is provided with a horizontal working surface 101; the fixed seat 2 is arranged on the horizontal working surface 101 of the leveling member 1; a through chamber 201 for accommodating a slice is formed in the fixed seat 2, and one end of the chamber 201 is connected to the horizontal working surface 101; a plurality of locking members for fixing the slice in the through chamber 201 are arranged on the fixed seat 2. During use, the cut surface of the metallographic slice 4, that is, the surface to be observed, is placed downward on the horizontal working surface 101 of the leveling member 1, and the fixed seat 2 is sleeved on the metallographic slice 4 so that the metallographic slice 4 is located in the chamber 201 of the fixed seat 2. The designed height of the fixed seat 2 is preferably higher than the thickness of the metallographic slice 4. Then, the fixed seat 2 and the metallographic slice 4 are simultaneously pressed by hand or other means so that the observation surface of the metallographic slice 4 is closely attached to the horizontal working surface 101. After ensuring that its surface is as parallel to the horizontal working surface 101 as possible, the metallographic slice 4 is fixed in the chamber 201 through the locking members to keep its current state. Finally, the fixed seat 2 is turned over so that the observation surface of the metallographic slice 4 faces upward and is placed under a metallographic microscope for metallographic analysis. At this time, the cut surface of the slice is substantially parallel to the lower end surface of the sleeve, thereby ensuring that the cut surface of the slice is parallel to the end surface of the lens and the image is clear.

[0022] The metallographic slice 4 is generally circular. Therefore, the fixed seat 2 can be selected as a hollow cylindrical structure such as a bushing, and the size is determined according to the metallographic slice 4. The leveling member 1 can be selected as a flat plate or a workbench according to actual needs as long as it has a horizontal operation table surface.

[0023] Further, a plurality of threaded holes communicating with the chamber 201 are formed on the side wall of the fixed seat 2; the locking member includes a fixing bolt 3 matching with the threaded holes; the fixing bolt 3 is movably connected to the fixed seat 2 through the threaded holes. After the metallographic slice 4 is installed in place, one end of the fixing bolt 3 is inserted into the threaded hole and the fixing bolt 3 is screwed so that its end face extends into the chamber 201 and contacts the side wall of the slice. The slice is fixed in the chamber 201 by applying force to the side wall of the slice through a plurality of fixing bolts 3.

[0024] Preferably, the plurality of threaded holes are evenly distributed in the circumferential direction of the fixed seat 2 to ensure that the slice is evenly stressed and does not shift.

[0025] In a refined embodiment, the slicing observation surface leveling jig further includes a connecting member; the fixed seat 2 is detachably mounted on the leveling member 1 through the connecting member. During use, the fixed seat 2 can be fixed on the leveling member 1 through the connecting member, and then the metallographic slice 4 is placed in the chamber 201 of the fixed seat 2 for adjustment. After the slice is adjusted in place, the restriction of the connecting member on the fixed seat 2 is released, and the fixed seat 2 is flipped. The connecting member can be selected according to the actual situation, which can realize the detachable connection between the fixed seat 2 and the leveling member 1, and ensure that the fixed seat 2 is fixed on the horizontal working surface 101 of the leveling member during the leveling process without deviation.

[0026] Since manually pressing the slice is time-consuming and laborious and may affect the fitting accuracy, in an optimized embodiment, the slicing observation surface leveling jig further includes a pressing plate assembly for making the observation surface of the slice adhere to the horizontal working surface 101 of the leveling member 1. During use, the cutting surface of the metallographic slice 4 is placed downward on the horizontal working surface 101 of the leveling member 1, and the fixed seat 2 is used to enclose the metallographic slice 4 so that the metallographic slice 4 is located in the chamber 201 of the fixed seat 2. Then the pressing plate assembly is started to press the metallographic slice 4 downward, so that the observation surface of the metallographic slice 4 closely adheres to the horizontal working surface 101, saving labor loss.

[0027] Specifically, the pressing plate assembly includes a lifting device and a pressing plate; the pressing plate is installed at the lifting end of the lifting device, and the size of the pressing plate is smaller than the cross-sectional size of the through chamber 201. During use, the lifting device is arranged near the fixed seat 2 so that the pressing plate is located above the fixed seat 2. After the metallographic slice 4 is placed in the chamber 201 of the fixed seat 2, the lifting device is started to make the pressing plate move downward and enter the chamber 201 to press the slice tightly. The metallographic slice 4 is fixed in the chamber 201 through a locking member, and then the pressing plate rises and leaves the fixed seat 2, and the fixed seat 2 is flipped so that the observation surface of the metallographic slice 4 faces upward and is placed under a metallurgical microscope for metallurgical analysis.

[0028] Preferably, a buffer pad is provided on the pressing surface where the pressing plate contacts the slice. On the one hand, it prevents the slice from being broken due to the force applied by the pressing plate. On the other hand, the buffer pad can disperse the uneven force caused by the uneven cutting surface of the slice when the pressing plate presses down, making the cutting surface of the slice more closely adhere to the horizontal working surface 101 of the leveling member 1. The buffer pad can be selected as a rubber buffer pad or other elastic buffer pads according to needs.

[0029] In summary, the slicing observation surface leveling jig provided by the present utility model has a simple structure and convenient operation, is applicable to the analysis of metallographic slices 4, can quickly adjust the metallographic slices 4 to make their surfaces as parallel as possible to the microscope lens surface, improves the clarity of the entire metallographic image, reduces the difficulty of the leveling work, and improves the efficiency of the metallographic slice 4 analysis.

[0030] The above examples are only illustrative of the present utility model and do not constitute a limitation on the scope of protection of the present utility model. Any design identical or similar to the present utility model falls within the scope of protection of the present utility model.
