Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a sampling device for bonded NdFeB magnetic powder. Background Technology

[0002] Bonded NdFeB is a type of synthetic magnet. Bonded NdFeB magnetic powder refers to a type of hard magnetic single-domain particle. Bonded NdFeB magnetic powder is a magnet made by mixing a certain amount of bonded NdFeB magnetic powder with a certain proportion of binder and then molding it according to a certain molding process. Bonded magnets have high dimensional accuracy and can be made into relatively complex magnetic components. They also have the characteristics of one-time molding and multi-pole orientation. In order to check the quality of bonded NdFeB magnetic powder, workers usually use a sampling device to take samples of the bonded NdFeB magnetic powder and then test the quality.

[0003] The patent titled "A Low-Oxygen Sampling Device for Micro-Sintered NdFeB Magnetic Powder" (patent application number: 201720942884.1) discloses a low-oxygen sampling device for micro-sintered NdFeB magnetic powder, belonging to the field of powder metallurgy technology. It includes a sampling device and a sample container. The sampling device is hollow, forming a receiving cavity. The sampling device is connected to a nitrogen filling pipe and a nitrogen outlet pipe. The nitrogen filling pipe and the nitrogen outlet pipe are connected to the receiving cavity. The sampling device has a side opening. A sleeve is installed on the side opening. A stainless steel telescopic tube is installed on the inner wall of the sampling device. The sample container is fixedly installed at the bottom end of the stainless steel telescopic tube. This technical solution achieves quantitative control of the oxygen content in the sampling environment, accurate positioning of the sampling location, reduces material waste, simplifies the workflow, accelerates sampling speed, saves manpower and resources, and improves work efficiency.

[0004] In the above-mentioned case, because the stainless steel telescopic tube is fixedly connected to the sample container, it is not easy to detach the sample container from the stainless steel telescopic tube when it needs to be replaced, which brings inconvenience to the disassembly and replacement of the sample container. Furthermore, when the sample container is used to sample magnetic powder, it needs to be inserted into the interior of the magnetic powder, causing magnetic powder to accumulate on the top of the sample container and the top of the outer sealing sleeve when it is removed. This requires cleaning of the accumulated magnetic powder, resulting in time-consuming and labor-intensive problems and making magnetic powder sampling operations inconvenient. Therefore, it is necessary to propose a bonded NdFeB magnetic powder sampling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sampler for bonded NdFeB magnetic powder, which solves the problems mentioned in the background art. Because the stainless steel telescopic tube is fixedly connected to the sample container, it is difficult to easily remove the sample container when it needs to be replaced, thus causing inconvenience in disassembling and replacing the sample container. Furthermore, when the sample container is sampling magnetic powder, it needs to be inserted into the magnetic powder, causing magnetic powder to accumulate on the top of the sample container and the top of the outer sealing sleeve when the sample container is removed. This requires cleaning of the accumulated magnetic powder, resulting in time-consuming and labor-intensive processes, and thus causing inconvenience in the magnetic powder sampling operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampler for bonded NdFeB magnetic powder, comprising:

[0007] Stainless steel telescopic pipe;

[0008] A fixing plate, the top of which is fixedly connected to the bottom end of the stainless steel telescopic tube;

The side of the limiting plate is fixedly connected to one end of the spring. The bottom of the connecting block is fixedly connected to the top of the sample container body, and a limiting groove is opened inside the connecting block. The limiting groove is inserted into the limiting block.

[0013] Preferably, the outer side of the limiting plate is slidably connected to the inner side of the limiting frame, the other end of the spring away from the limiting plate is fixedly connected to the side of the inner cavity of the limiting frame, and the inner side of the spring is slidably connected to the outer side of the limiting block.

[0014] The fixing plate has an internal mounting groove, which is inserted into the connecting block.

[0015] Preferably, a flow guide is slidably connected to the outside of the stainless steel telescopic tube, and a second magnet is fixedly connected to the inner wall of the flow guide.

[0019] Preferably, the top of the sample container body is provided with a discharge port.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. By setting up the installation components, when disassembling and replacing the main body of the sample container, simply pull the limiting block to separate the limiting block from the limiting groove opened inside the connecting block, and the main body of the sample container can be quickly disassembled and replaced. Moreover, since the top of the main body of the sample container has a discharge port, the magnetic powder sampled inside the disassembled sample container can be quickly poured out through the discharge port, avoiding the problem of inconvenient material discharge caused by relying solely on the sampling hole to pour the magnetic powder, thus bringing convenience to the use of the device.

[0022] 2. By setting up a flow guide, the magnetic powder can be guided during the sampling process of the sample container body, avoiding the accumulation of magnetic powder on the top of the sample container body, which would otherwise require cleaning by workers, thus improving the efficiency of magnetic powder sampling. At the same time, since the first magnet and the second magnet are attracted to each other, the first magnet can be used to limit and fix the flow guide, bringing convenience to the use of the flow guide.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figures 1-6 The device shown is a bonded NdFeB magnetic powder sampling device, comprising:

[0032] Stainless steel telescopic pipe 1; its telescopic function can be flexibly adjusted according to the sampling depth requirements, making it convenient to perform sampling operations at different height positions, thus improving the flexibility and applicability of sampling.

[0033] The top of the fixing plate 2 is fixedly connected to the bottom end of the stainless steel telescopic pipe 1; its top is fixedly connected to the bottom end of the stainless steel telescopic pipe 1, which serves to connect and support other components, and ensure the structural stability and reliability of the entire device.

[0034] The sample container body 3 is located at the bottom of the fixed plate 2; it is used to hold the magnetic powder sample that has been taken out.

[0035] The mounting components are located on top of the fixing plate 2, allowing the sample container body 3 to be easily installed and disassembled, facilitating cleaning, replacement, or maintenance of the sample container body 3.

[0036] The mounting components include a limiting frame 4, a limiting block 5, a limiting plate 6, a spring 7, and a connecting block 10. The outside of the limiting block 5 is slidably connected to the inside of the limiting frame 4, and the outside of the limiting block 5 is fixedly connected to the inside of the limiting plate 6. The side of the limiting plate 6 is fixedly connected to one end of the spring 7. The bottom of the connecting block 10 is fixedly connected to the top of the sample container body 3, and a limiting groove 13 is provided inside the connecting block 10. The limiting groove 13 is inserted into the limiting block 5. The outside of the limiting plate 6 is slidably connected to the inside of the limiting frame 4. The other end of the spring 7 away from the limiting plate 6 is fixedly connected to the side of the inner cavity of the limiting frame 4, and the inside of the spring 7 is slidably connected to the outside of the limiting block 5. An installation groove 14 is provided inside the fixing plate 2, and the installation groove 14 is inserted into the connecting block 10. When it is necessary to disassemble the sample container body 3, simply pull the limiting block 5 to separate the limiting block 5 from the limiting groove 13 inside the connecting block 10, and then pull the sample container body 3 downward to separate the connecting block 10 from the mounting groove 14 inside the fixing plate 2. This allows for quick disassembly and replacement of the sample container body 3, thus facilitating the use of the device.

[0037] In addition, a flow guide shroud 11 is slidably connected to the outside of the stainless steel telescopic tube 1, and a second magnet 12 is fixedly connected to the inner wall of the flow guide shroud 11. A movable block 8 is slidably connected to the inside of the limiting block 5, and a first magnet 9 is fixedly connected to the end of the movable block 8 away from the limiting block 5. The first magnet 9 and the second magnet 12 attract each other. During the sampling of magnetic powder by the sample container body 3, the flow guide shroud 11 can be used to guide the magnetic powder, avoiding the accumulation of magnetic powder on the top of the sample container body 3, which would require subsequent cleaning by workers, thus improving the efficiency of magnetic powder sampling. At the same time, since the first magnet 9 and the second magnet 12 attract each other, the first magnet 9 can be used to conveniently limit and fix the flow guide shroud 11, bringing convenience to the use of the flow guide shroud 11. The movable block 8 can extend into the interior of the limiting block 5, making it easy for the limiting block 5 to separate from the limiting groove 13 opened inside the connecting block 10.

[0038] Finally, a sampling hole 15 is provided on the outside of the sample container body 3, and a cone head 16 is fixedly connected to the bottom of the sample container body 3.

The height of the rubber sealing sleeve 17 is greater than the height of the sampling hole 15, and the top of the rubber sealing sleeve 17 is a sloping surface. A discharge port 18 is provided on the top of the sample container body 3. After sampling, the rubber sealing sleeve 17 can be lowered to seal the sampling hole 15, preventing magnetic powder from leaking out of the sampling hole 15. At the same time, since the top of the rubber sealing sleeve 17 is a sloping surface, it can guide the magnetic powder and prevent accumulation. Moreover, the magnetic powder sampled from inside the disassembled sample container body 3 can be quickly poured out through the discharge port 18, avoiding the problem of inconvenient discharge caused by relying solely on the sampling hole 15 to pour the magnetic powder, thus bringing convenience to the use of the device.

[0039] Working principle: When magnetic powder needs to be sampled, the sample container body 3 can be inserted into the magnetic powder bucket. After reaching the required sampling position, the stainless steel telescopic tube 1 is rotated to allow the magnetic powder to enter the sampling hole 15. After sampling, the rubber sealing sleeve 17 can be lowered to seal the sampling hole 15, preventing magnetic powder from leaking out. During the sampling process, the flow guide 11 can be used to guide the magnetic powder, preventing it from accumulating on the top of the sample container body 3 and requiring subsequent cleaning by workers, thus improving the efficiency of magnetic powder sampling. At the same time, since the first magnet 9 and the second magnet 12 are attracted to each other, the first magnet 9 can be used to facilitate the flow guide 11. The limiting and fixing mechanism facilitates the use of the flow guide shroud 11. When it is necessary to disassemble the sample container body 3, simply pull the limiting block 5 to separate the limiting block 5 from the limiting groove 13 inside the connecting block 10, and then pull the sample container body 3 downward to separate the connecting block 10 from the mounting groove 14 inside the fixing plate 2. This allows for quick disassembly and replacement of the sample container body 3, thus facilitating the use of the device. Furthermore, the magnetic powder sampled from inside the disassembled sample container body 3 can be quickly poured out through the discharge port 18, avoiding the problem of inconvenient material discharge caused by relying solely on the sampling hole 15 to pour the magnetic powder. This further facilitates the use of the device.
