[0035] In the related art, there is a technical problem that using a drill bit to drill samples from pig iron is inconvenient to use. The embodiment of the present application provides a positioning tool, which can at least solve the above technical problem to a certain extent.

[0036] For ease of understanding, here is provided Figure 1 , Figure 1 The schematic diagram of the structure of the pig iron in some embodiments or some embodiments is shown, and reference is made to Figure 1 , the pig iron 100 may be in block form, Figure 1The circle on the pig iron 100 is the sampling position. The size of the pig iron 100 is different, and the sampling position and size on the pig iron 100 are also different. The present application can be used for effective fixation to reduce the possible slip between the pig iron 100 and the drill bit.

[0037] Figure 2 A simplified schematic diagram of the structure of a positioning tool in some embodiments or certain embodiments is shown. Figure 3 shows a schematic diagram of the structure of a workbench in some embodiments or certain embodiments, Figure 4 FIG. 1 shows a schematic diagram of a local structure of a positioning tool in some embodiments or some embodiments, referring to FIG. Figure 2 to Figure 4 The present application provides a positioning tool that can be used to position pig iron 100, including a workbench 1 and at least two clamping bodies 2, a rotating part 3, a limiting part 4 and a fixing part 5. The workbench 1 is provided with at least two slide grooves 11 that are parallel and pass through the workbench 1.

[0038] The clamp body 2 is placed on the workbench 1 and is used to cooperate with the adjacent clamp body 2 to position the pig iron 100 .

[0039] The rotating member 3 is threadedly inserted into the corresponding clamp body 2 and extends into the sliding groove 11 .

[0040] The limiting member 4 is located in the slide groove 11 and is threadably matched with the rotating member 3 so as to abut against the slide groove 11 .

[0041] The fixing member 5 is threadedly sleeved on the rotating member 3 and is used to limit the rotational freedom of the rotating member 3 and the clamp body 2 .

[0042] In the positioning tool, at least two chute grooves 11 are arranged in parallel and pass through the workbench 1 on the workbench 1, at least two clamp bodies 2 are placed on the workbench 1, and the two adjacent clamp bodies 2 can cooperate to clamp and position the pig iron 100, and then the rotating member 3 is threadedly inserted into the corresponding clamp body 2 and extends into the chute groove 11, and the limiter 4 located in the chute groove 11 is threadedly matched with the rotating member 3. The rotating member 3 is rotated relative to the clamp body 2, and the rotating member 3 drives the limiter 4 to rotate until the limiter 4 and the chute groove 11 are against each other, and the rotating member 3 is subjected to resistance, and there is an interaction force between the chute groove 11, the clamp body 2 where the chute groove 11 is located, and the limiter 4, and then the fixing member 5 is threadedly sleeved on the rotating member 3 to limit the rotational freedom of the rotating member 3 and the clamp body 2, and play a positioning role for the rotating member 3, the limiter 4 and the clamp body 2. The position of the clamp body 2 is fixed, so the pig iron 100 can be stably clamped and positioned, and the position of the clamp body 2 can be adjusted by the position of the rotating member 3 and the limit member 4 relative to the slide slot 11, so as to clamp and position the pig iron 100 of different sizes, and then sample the pig iron 100 after positioning and test the sample, and the clamp body 2 can be removed after sampling. The positioning tool can reduce the safety hazard caused by the slippage between the pig iron 100 of different sizes and the drill bit, and the overall operation is convenient and will not affect other uses of the workbench 1, and the sampling efficiency of the pig iron 100 can be improved.

[0043] Compared with the method in which the pig iron 100 has an irregular size or shape and needs to be manually fixed on a lathe or a platform, the clamping and positioning of the pig iron 100 by the clamp body 2 is more stable and quick, which can shorten the time required for sampling and improve the sampling efficiency.

[0044] In some embodiments, the slide groove 11 is a T-shaped groove, and along the width direction of the slide groove 11 , the maximum width value of the limiting member 4 is located between two width values ​​of the T-shaped groove.

[0045] The slide groove 11 is a T-shaped groove, and the maximum width value of the limit member 4 is between the two width values ​​of the T-shaped groove. The limit member 4 can be located in the bottom of the T-shaped groove with a larger width. The limit member 4 can abut against the T-shaped groove in the width direction and the height direction of the T-shaped groove to play a limiting role, which can improve the positioning effect of the limit member 4, the rotating member 3 and the clamping body 2.

[0046] It should be noted that the two width values ​​of the T-slot are two different width values ​​of the T-slot in the width direction.

[0047] In some embodiments, the limiting member 4 is block-shaped or plate-shaped, and the rotating member 3 is a columnar structure with threads.

[0048] The block-shaped or plate-shaped limiting member 4 cooperates with the T-slot to achieve a better limiting effect. The rotating member 3 is a columnar structure with threads, which facilitates the insertion and cooperation between the rotating member 3, the clamp body 2 and the limiting member 4, and also facilitates the overall production.

[0049] In some embodiments, the slide groove 11 may also be a rectangular groove or a dovetail groove, the stopper 4 may also be a dovetail protrusion, and the rotating member 3 may be a bolt or a stud, so as to realize the limit between the stopper 4 and the rotating member 3, and the disassembly and assembly between the rotating member 3, the clamp body 2 and the workbench 1. This application does not limit this.

[0050] In some embodiments, the clamp body 2 is provided with a connected supporting portion 21 and a limiting portion 22, the supporting portion 21 is placed on the workbench 1, the limiting portion 22 is located on one side of the workbench 1, and both the supporting portion 21 and the limiting portion 22 are provided with a threaded hole 23 for threaded cooperation with the rotating member 3.

[0051] The support part 21 of the clamp body 2 is placed on the workbench 1, and the limit part 22 is located on one side of the workbench 1. The support part 21 can move to a certain extent relative to the workbench 1. When the support part 21 moves to a certain range, the limit part 22 can also abut against the side of the workbench 1, thereby increasing the clamping and positioning effect of the pig iron 100 and improving the sampling efficiency of the pig iron 100. The threaded hole 23 of the support part 21 is threadedly matched with the rotating part 3, and the rotating part 3 can be inserted, and the rotating part 3 is then inserted into the slide groove 11 to cooperate with the limit part 4. The threaded hole 23 of the limit part 22 can also be used for the rotating part 3 to be inserted into the slide groove 11 from one side of the workbench 1, thereby extending the service life of the clamp body 2.

[0052] In some embodiments, the threaded hole 23 located at the limiting portion 22 is opposite to the end of the slide slot 11. This facilitates the insertion of the rotating member 3 into the slide slot 11 from one end of the slide slot 11, which is beneficial to improving the sampling efficiency.

[0053] In some embodiments, the workbench 1 is in a cube shape, and the clamp body 2 is an L-shaped plate, and one surface of the L-shaped plate is placed on the workbench 1 .

[0054] The cube-shaped workbench 1 is convenient for placing the pig iron 100, and one surface of the L-shaped plate is placed on the workbench 1 to facilitate placing the clamp body 2 and supporting the pig iron 100.

[0055] In some embodiments, the L-shaped plate can be divided into two parts by its bending part, and the two parts can be respectively configured as the support part 21 and the limit part 22. The clamp body 2 can also be set as a disc shape, and the clamp body 2 can be a block or plate structure placed as a whole on the workbench 1. This application does not limit this.

[0056] In some embodiments, the fixing member 5 includes a nut body 51 and at least two control parts 52 . The nut body 51 is threadedly sleeved on the rotating member 3 , and the at least two control parts 52 are connected to the side of the nut body 51 in a surrounding manner.

[0057] The fixing member 5 includes a nut body 51, which can be easily matched with the rotating member 3. The control part 52 surrounds the nut body 51 and is connected to the side of the nut body 51, which can increase the operable space of the nut body 51, so that the nut body 51 can rotate relative to the rotating member 3, thereby improving the positioning efficiency of the clamping body 2 and improving the sampling efficiency of the pig iron 100.

[0058] In some embodiments, the control portion 52 is plate-shaped, and the control portion 52 extends to a side away from the clamp body 2. The control portion 52 extends to a side away from the clamp body 2, which can increase the operable space of the nut body 51, so that the nut body 51 rotates relative to the rotating member 3, improves the positioning efficiency of the clamp body 2, and improves the sampling efficiency of the pig iron 100.

[0059] In some embodiments, the control portion 52 may also be configured to be in a strip or rod shape, etc., and this application does not impose any limitation on this.

[0061] Positioning tool as before.

[0062] The sampling drill 10 is used for drilling pig iron 100 placed on a positioning tool to drill a sample from the pig iron 100.

[0063] The sampling member 20 is used for contacting with the sample to separate the sample from the pig iron 100 .

[0064] The structure of the positioning tool and its corresponding technical effects can be referred to above, and will not be repeated here. The drill bit and the sampling piece 20 can facilitate the drilling of the pig iron 100 and the acquisition of samples.

[0065] In some embodiments, the sampling member 20 is used to contact and adsorb the sample to separate the sample from the pig iron 100. The adsorption effect is good and the integrity of the sample can be maintained, which is beneficial to improving the sampling and detection efficiency of the sample.

[0066] In some embodiments, the sampling member 20 may be a magnet, or a suction cup, or a device with a magnet or a suction cup. The sampling member 20 may also be a clamp or other structure, which is not limited in the present application.

[0067] In some embodiments, the sampling drill bit 10 and the workbench 1 in the positioning tool can be respectively the drill bit and the workbench 1 in a vertical drilling machine, so as to facilitate the sampling operation.

[0068] In some embodiments, a vertical drilling machine is commonly used in machinery manufacturing and repair factories to process holes in medium and small workpieces. Before the operation, the position of the workpiece on the workbench 1 must be adjusted so that the center line of the processed hole is aligned with the tool axis. During processing, the workpiece is fixed, and the spindle rotates in the sleeve and feeds axially with the sleeve. The workbench 1 and the spindle box can be adjusted along the column guide rail to accommodate workpieces of different heights. In the metallurgical industry, sampling of pig iron 100 is a key process before steelmaking, and a vertical drilling machine is required. The drilling machine is used to open multiple holes on the surface of the pig iron 100. During the drilling process, magnets and sampling paper are used to collect the drilled iron filings to provide samples for the subsequent process and detect the component content in the sample.
