Description

Technical Field

[0001] This utility model relates to the field of fluorescent magnetic particle testing technology, specifically a feeding device for anti-clogging bolt fluorescent magnetic particle testing. Background Technology

[0002] Fluorescent magnetic particle testing equipment for bolts is a non-destructive testing technique that uses magnetic particles to detect surface and near-surface defects in bolts. It is suitable for detecting defects such as cracks, folds, and inclusions in ferromagnetic materials like steel bolts. However, existing fluorescent magnetic particle testing equipment for bolts has some shortcomings, such as:

[0003] A fluorescent magnetic particle flaw detection device, application number CN202020393755.3, integrates the spraying of fluorescent magnetic powder and light detection, thereby improving the efficiency of flaw detection. However, in actual use, the device may experience blockage of the fluorescent magnetic powder during the feeding process, which may cause the nozzle to malfunction when spraying bolts due to the blockage.

[0004] Therefore, we propose a feed device for anti-clogging bolt fluorescent magnetic particle flaw detection to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for bolt fluorescent magnetic particle flaw detection that prevents clogging, in order to solve the problem of clogging during feeding of fluorescent magnetic particles currently on the market, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for anti-clogging bolt fluorescent magnetic particle flaw detection, comprising a device body, a nozzle installed at the bottom of the device body, and a storage bin at the top of the device body;

[0007] The device body is equipped with a drive mechanism and a transmission chamber. The left end of the drive mechanism is connected to a material conveying mechanism, which is located inside the transmission chamber. The bottom of the transmission chamber is equipped with a guide channel connected to the nozzle. The material conveying mechanism includes a first gear, and the rear end of the first gear meshes with a second gear. The left ends of the first gear and the second gear are each equipped with a set of auger shafts, and the outer side of the auger shafts is in contact with the inside of the transmission chamber.

[0008] A placement platform is installed on the outside of the main body of the device, and a fixing plate is provided at the bottom of the placement platform. The placement platform fixes the bolted workpiece through the fixing plate.

[0009] By driving the first and second gears to rotate via the drive motor, the two sets of auger shafts can rotate inside the transmission chamber. This allows the fluorescent magnetic powder inside the transmission chamber to be separated by the two sets of auger shafts when it is being transported to the guide channel, thus preventing the fluorescent magnetic powder from sticking together due to magnetic force or other reasons and causing blockage.

[0010] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor, and a first sprocket is connected to the left end of the drive motor. A chain is engaged on the outside of the first sprocket, and a second sprocket is engaged on the top of the chain.

[0011] The above technical solution enables the drive mechanism to be more stable when connected to the crushing mechanism or drive shaft, thus increasing the stability of the equipment during operation.

[0012] As a preferred technical solution of this utility model, the first sprocket is fixedly connected to the first gear, and the second sprocket is connected to the inside of the device body through a bearing seat, and the top of the transmission chamber is fixedly connected to the storage chamber.

[0013] The above technical solution enables the second sprocket to be more stable when connected to the main body of the device, thereby increasing the stability of the drive mechanism during operation.

[0014] As a preferred technical solution of this utility model, a filter screen is provided on the top of the storage bin, and a drive shaft is provided on the left end of the second sprocket. An insulating crushing shaft is connected to the left end of the drive shaft. The insulating crushing shaft is located on the top of the filter screen and is rotatably connected to the inside of the transmission bin.

[0015] The above technical solution enables the fallen fluorescent magnetic powder to be crushed by the insulated crushing shaft before passing through the filter screen, thus preventing the fluorescent magnetic powder from sticking together and being unable to pass through the filter screen.

[0016] As a preferred technical solution of this utility model, a sloping groove is provided at the corner of the transmission chamber, and the sloping groove can transmit the fluorescent magnetic powder that falls to the bottom of the transmission chamber to the auger shaft.

[0017] The above technical solution enables the fluorescent magnetic powder to be transported to the auger shaft through the inclined groove, avoiding blockage at the corner of the transport chamber.

[0018] As a preferred technical solution of this utility model, the bottom of the transmission chamber is fixedly connected to the guide channel, and the top of the nozzle is provided with a receiving chamber, and the top of the nozzle is connected to the guide channel through the receiving chamber.

[0019] The above technical solution enables the flow channel to transfer fluorescent magnetic powder to the nozzle more stably, thereby avoiding leakage of fluorescent magnetic powder.

[0020] As a preferred technical solution of this utility model, a set of striking rods is provided at the left end of the auger shaft, and the top of the striking rods can fit against the filter screen, and the striking rods are rotatably connected to the inside of the transmission chamber.

[0021] The above technical solution enables the striking rod to strike the surface of the filter screen when rotating, thereby causing the fluorescent magnetic powder adhering to the surface of the filter screen to fall off, thus preventing the filter screen from being clogged by the fluorescent magnetic powder during use.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by driving the first gear and the second gear to rotate by the drive motor, the two sets of auger shafts can rotate inside the transmission chamber, so that when the fluorescent magnetic powder inside the transmission chamber is transported to the guide channel, the fluorescent magnetic powder can be separated by the two sets of auger shafts, avoiding the problem of fluorescent magnetic powder sticking together due to magnetic force or other reasons, thus preventing blockage.

[0023] Furthermore, by placing the insulating crushing shaft at the top of the filter screen, the falling fluorescent magnetic powder can be crushed by the insulating crushing shaft before passing through the filter screen, thus preventing the fluorescent magnetic powder from sticking together and being unable to pass through the filter screen.

[0024] Furthermore, the striking rod allows it to strike the surface of the filter screen when rotating, causing the fluorescent magnetic powder adhering to the filter screen surface to fall off, thus preventing the filter screen from being clogged by the fluorescent magnetic powder during use.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1: To address the problem of fluorescent magnetic powder easily clogging and thus affecting flaw detection in the prior art, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a feeding device for anti-clogging bolt fluorescent magnetic particle flaw detection, including a device body 1, a nozzle 2 installed at the bottom of the device body 1, and a storage bin 15 provided at the top of the device body 1;

[0035] The main body 1 of the device is equipped with a drive mechanism and a transmission chamber 10. The left end of the drive mechanism is connected to a material conveying mechanism, which is located inside the transmission chamber 10. The bottom of the transmission chamber 10 is provided with a guide groove 11 connected to the nozzle 2. The material conveying mechanism includes a first gear 7, and a second gear 8 meshes with the rear end of the first gear 7. The left ends of the first gear 7 and the second gear 8 are each provided with a set of auger shafts 9, and the outer side of the auger shafts 9 is in contact with the inside of the transmission chamber 10.

[0036] A placement platform 19 is installed on the outside of the main body 1 of the device, and a fixing plate is provided at the bottom of the placement platform 19. The placement platform 19 fixes the bolt workpiece through the fixing plate.

[0037] The device body 1 is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 3. The left end of the drive motor 3 is connected to a first sprocket 4. A chain 5 is engaged on the outside of the first sprocket 4, and a second sprocket 6 is engaged on the top of the chain 5.

[0038] The first sprocket 4 is fixedly connected to the first gear 7, and the second sprocket 6 is connected to the inside of the device body 1 through the bearing seat. The top of the transmission chamber 10 is fixedly connected to the storage chamber 15. The top of the storage chamber 15 is provided with a filter screen 12. The left end of the second sprocket 6 is provided with a drive shaft 13, and the left end of the drive shaft 13 is connected to an insulating crushing shaft 14. The insulating crushing shaft 14 is located on top of the filter screen 12, and the insulating crushing shaft 14 is rotatably connected to the inside of the transmission chamber 10.

[0039] The corner of the transmission chamber 10 is provided with a sloping groove 17, which can transport the fluorescent magnetic powder that falls to the bottom of the transmission chamber 10 to the auger shaft 9; the bottom of the transmission chamber 10 is fixedly connected to the guide channel 11, and the top of the nozzle 2 is provided with a receiving chamber 16, and the top of the nozzle 2 is connected to the guide channel 11 through the receiving chamber 16.

[0040] Example 2: This example discloses another anti-clogging method, which differs from Example 1, as follows: Figures 6-7 As shown, the difference between this embodiment and embodiment 1 is that: a set of striking rods 18 are provided at the left end of the auger shaft 9, and the top of the striking rods 18 can fit against the filter screen 12, and the striking rods 18 are rotatably connected to the inside of the transmission chamber 10; when the first gear 7 and the second gear 8 drive the auger shaft 9 to rotate in opposite directions, the striking rods 18 will also rotate, so that the two sets of striking rods 18 strike the top of the filter screen 12, thereby causing the fluorescent magnetic powder adhered to the surface of the filter screen 12 to fall off, preventing the filter holes of the filter screen 12 from becoming blocked and affecting the feeding operation.

[0041] Example 3: The difference between this example and Example 1 is that a scraper is installed on the outside of the insulating crushing shaft 14, so that the scraper is in contact with the inner wall of the top of the transmission chamber 10, thereby scraping off the fluorescent magnetic powder adhering to the inner wall of the top of the transmission chamber 10, avoiding the problem of fluorescent magnetic powder adhering to the top of the transmission chamber 10 and causing blockage.

[0042] Working principle: When using this anti-clogging bolt fluorescent magnetic particle flaw detection feeding device, first connect the equipment power supply and the power grid, then install the bolt workpiece in the fixed plate at the bottom of the placement platform 19, so that the nozzle 2 set at the bottom of the main body 1 faces the fixed plate at the bottom of the placement platform 19. Then, the fluorescent magnetic powder inside the storage bin 15 is transferred to the transfer bin 10. At the same time, the drive mechanism drives the conveying mechanism to run, so that the first gear 7 and the second gear 8 mesh, which enables the first gear 7 and the second gear 8 to drive the two sets of auger shafts 9 to rotate in opposite directions. Thus, the two sets of auger shafts 9 rotate inside the transfer bin 10, and the fluorescent magnetic powder inside the transfer bin 10 is also transferred to the guide channel 11 under the drive of the two sets of auger shafts 9, so that the guide channel 11 transfers the fluorescent magnetic powder to the nozzle 2.

[0043] When the drive mechanism is running, the drive motor 3 drives the first sprocket 4 to rotate, which in turn drives the second sprocket 6 to rotate via the chain 5. The first sprocket 4 also drives the first gear 7 to rotate. At the same time, the second sprocket 6 drives the insulating crushing shaft 14 to rotate at the top of the transfer chamber 10 via the drive shaft 13. This allows the fluorescent magnetic powder to be separated by the insulating crushing shaft 14 when it falls, preventing it from sticking together. Then, the fluorescent magnetic powder is transferred to the bottom of the transfer chamber 10 through the filter screen 12.

[0044] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
