[0033] In the description of the embodiments, "several", "plurality" and "multiple" represent at least 2. It can be any number such as 2, 3, 4, 5, 6, 7, 8, 9, and even more than 9.

[0034] Example 1

[0035] The utility model discloses a testing tool for exploring the electrophoresis quality of sheet metal gaps, such as Figures 1 to 4 As shown, it includes a tool body 1, a sheet metal test piece 2, a gasket 3 and a limiter 4; the limiter 4 is connected to the tool body 1, and the distance between the limiter 4 and the tool body 1 is adjustable.

[0036] The tooling body 1 is used to install the sheet metal specimen 2, the gasket 3 and the limiter 4. The sheet metal specimen 2 and the gasket 3 can be stacked and placed on the top surface of the tooling body 1 or in the groove formed by the tooling body 1. The limiter 4 is used to limit the position of the sheet metal specimen 2 and the gasket 3 to facilitate the electrophoresis test. By selecting gaskets 3 of different thicknesses or increasing or decreasing the number of gaskets 3, different gaps can be formed between adjacent sheet metal specimens 2. Correspondingly, the spacing between the limiter 4 and the tooling body 1 is adjustable, so that the limiter 4 can fix the position of the sheet metal specimen 2 and the gasket 3 well.

[0037] Before exploring the electrophoresis quality of the sheet metal gap, multiple sheet metal specimens 2 are placed between the limiter 4 and the tooling body 1, and gaskets 3 are set between adjacent sheet metal specimens 2. By selecting gaskets 3 of different thicknesses or increasing or decreasing the gaskets 3, a gap with a desired width is formed between adjacent sheet metal specimens 2, and the size of the gap is adjusted; then the spacing between the limiter 4 and the tooling body 1 is adjusted, such as Figures 1 to 3 As shown, the limiting member 4 and the tooling body 1 can abut against the surface of the sheet metal specimen 2 on the outside, thereby clamping and fixing the multiple sheet metal specimens 2, so that the positions of the multiple sheet metal specimens 2 remain stable during the exploration process.

[0038] When investigating the electrophoretic quality of the sheet metal gap, the test tooling is placed in the electrophoretic tank for electrophoresis, and after the electrophoresis is completed, the sheet metal specimen 2 is removed from between the limit piece 4 and the tooling body 1. By observing the surface of the sheet metal specimen 2, the electrophoretic quality of the sheet metal gap is investigated.

[0039] The utility model can simulate sheet metal structures with different gaps through the cooperation of the tooling body 1, the gasket 3, the limiter 4 and the sheet metal test piece 2, which is convenient for combination with actual use and meets the exploration needs of different sheet metal gaps.

[0040] The sheet metal specimen 2 may be a plate-like structure, preferably a square plate-like structure.

[0041] In one or more embodiments, the tool body 1 includes a bottom plate 11 and two side plates 12 , the two side plates 12 are respectively connected to two sides of the bottom plate 11 , and the distance between the stopper 4 and the bottom plate 11 is adjustable. At this time, the bottom plate 11 and the two side plates 12 cooperate to form a placement groove 13, and the cross-sectional shape of the placement groove 13 is configured to be similar to the shape of the sheet metal specimen 2. When the sheet metal specimen 2 slides into the placement groove 13, the inner side surfaces of the two side plates 12 can abut the two side edges of the sheet metal specimen 2, thereby limiting the lateral movement of the sheet metal specimen 2 and reducing the relative movement between the sheet metal specimens 2, which plays a role in controlling variables and improving test reliability; at the same time, the bottom plate 11 can cooperate with the limiting member 4 to squeeze the sheet metal specimen 2 between the two, so that the sheet metal specimen 2 and the gasket 3 are in close contact; at the same time, at this time, no shielding members are set on both sides of the tooling body 1, so that the corresponding two sides of the gap of the sheet metal specimen 2 in the placement groove 13 can be exposed to the outside, which can facilitate the electrophoresis liquid to enter the gap of the sheet metal specimen 2, improve the speed of electrophoresis, and shorten the test cycle.

[0042] The tool body 1 formed by the bottom plate 11 and the two side plates 12 may be U-shaped or H-shaped.

[0043] In one or more embodiments, the tooling body 1 also includes a locking member, which can apply opposite forces to the two side panels 12, so that the two side panels 12 can deform towards each other or have a tendency to deform, thereby clamping the sheet metal specimen 2 between the two side panels 12, ensuring that the inner sides of the two side panels 12 can abut against the two side edges of the sheet metal specimen 2, thereby ensuring the effect of limiting the movement of the sheet metal specimen 2.

[0044] The locking member may be a structure of bolts and nuts. Figures 2 to 4 As shown, locking through holes are opened on the side panels 12, and the locking through holes on the two side panels 12 correspond to each other one by one; the locking member includes a locking screw 51 and a locking nut 52 that are threadedly connected, and the locking screw 51 passes through the corresponding locking through holes on the two side panels 12, and the two side panels 12 are located between the head of the locking screw 51 and the locking nut 52. When the locking nut 52 is tightened on the locking screw 51, the head of the locking screw 51 and the locking nut 52 can apply opposite extrusion forces to the two side panels 12, thereby causing the two side panels 12 to deform towards each other or have a tendency to deform.

[0045] In one or more embodiments, considering that the electrophoresis quality of the gap between the sheet metal test piece 2 is different when the sheet metal test piece 2 is placed horizontally and vertically in the electrophoresis tank, the test fixture can be provided with two mounting modes, horizontal hanging and vertical hanging, so as to explore the electrophoresis quality of the sheet metal gap under different mounting modes. Specifically, the side plate 12 is provided with a horizontal hanging matching portion and a vertical hanging matching portion, and the horizontal hanging matching portion can suspend the fixture body 1 and make the sheet metal test piece 2 in the fixture body 1 horizontal, such as Figure 5 As shown; the vertical hanging matching portion can hang the tooling body 1 and make the sheet metal test piece 2 in the tooling body 1 vertical, such as Figure 6 shown.

[0046] Among them, the horizontal hanging matching part and the vertical hanging matching part can be matching structures adapted to the test site hanging device. Specifically, the test site hanging device is usually a plurality of hooks. At this time, the horizontal hanging matching part includes a first hanging hole 121, and each side plate 12 is provided with two first hanging holes 121 spaced apart in a direction parallel to the bottom plate 11. All the first hanging holes 121 on the two side plates 12 are hooked by a plurality of hooks, so that the bottom plate 11 is in a horizontal state. At this time, the sheet metal specimen 2 placed on the bottom plate 11 is also in a horizontal state; the vertical hanging matching part includes two second hanging holes 122, and each side plate 12 is provided with two second hanging holes 122 spaced apart in a direction perpendicular to the bottom plate 11. All the first hanging holes 121 on the two side plates 12 are hooked by a plurality of hooks, so that the bottom plate 11 is in a horizontal state. At this time, the sheet metal specimen 2 placed on the bottom plate 11 is also in a horizontal state.

[0047] Among them, Figure 1 , Figure 5 and Figure 6 As shown, one of the first hanging holes 121 and one of the second hanging holes 122 can be the same hole.

[0048] In one or more embodiments, the distance between the stopper 4 and the tool body 1 is adjustable, such as Figures 1 to 4 As shown, the tool body 1 may be provided with a mounting rod 6, the mounting rod 6 is a screw rod, and the limit member 4 is a nut adapted to the mounting rod 6. The limit member 4 is rotated on the mounting rod 6 so that the limit member 4 can be connected to different axial positions of the mounting rod 6, thereby achieving an adjustable distance between the limit member 4 and the tool body 1, so that the limit member 4 and the tool body 1 can abut against the surface of the sheet metal specimen 2 at the outermost side, thereby clamping and fixing multiple sheet metal specimens 2.

[0049] When the tool body 1 includes a bottom plate 11 , one end of the mounting rod 6 is connected to the bottom plate 11 , and the mounting rod 6 and the bottom plate 11 are perpendicular to each other.

[0050] Furthermore, the sheet metal specimen 2 has a through hole adapted to the mounting rod 6, and the mounting rod 6 passes through the sheet metal specimen 2 from the through hole of the sheet metal specimen 2. At this time, the mounting rod 6 can also limit the movement of the sheet metal specimen 2, while ensuring that the limit member 4 can contact the sheet metal specimen 2.

[0051] Furthermore, the gasket 3 has a through hole adapted to the mounting rod 6, thereby enabling the mounting rod 6 to pass through the sheet metal specimen 2 and the gasket 3 at the same time. At this time, the gasket 3 is always located between adjacent sheet metal specimens 2 under the restriction of the mounting rod 6, thereby ensuring the required gap between the sheet metal specimens 2 and preventing the gasket 3 from slipping out from between adjacent sheet metal specimens 2 and affecting observation.

[0052] The gasket 3 may be a larger structure that is mounted on multiple mounting rods 6 at the same time. In this case, only one gasket 3 is required between adjacent sheet metal specimens 2. It may also be a smaller structure that can only be mounted on a single mounting rod 6, such as Figure 4 As shown, at this time, a plurality of gaskets 3 can be arranged between adjacent sheet metal specimens 2, and the adjacent sheet metal specimens 2 can be supported by the plurality of gaskets 3. At this time, the gaskets 3 can be precision gaskets 3.

[0053] The number of mounting rods 6 can be one, two, three, or even more, preferably at least four, and the four mounting rods 6 correspond to the four corners of the sheet metal specimen 2. In the case where the sheet metal specimen 2 has through holes adapted to the mounting rods 6, through holes are respectively opened at the four corners of the sheet metal specimen 2, so that the four mounting rods 6 can respectively pass through the through holes at different corners of the sheet metal specimen 2. By clamping and fixing the sheet metal specimen 2 with nuts on at least four mounting rods 6, the possibility of the sheet metal specimen 2 tilting and causing the spacing to change can be effectively reduced, thereby improving the stability of the test process.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
