Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and particularly relates to a flatness detection device for silicon steel sheets of a DC brushless iron core. Background Technique

[0002] During the production process, problems such as uneven stacking and deviation may occur when stacking silicon steel sheets. These problems will cause the flatness of the silicon steel sheets to decrease. For a DC brushless iron core, if the flatness does not meet the standard, it will lead to an increase in iron core loss, a decrease in motor efficiency, and may even cause problems such as noise and vibration.

[0003] However, it is very difficult to clearly and timely detect the flatness of silicon steel sheets only by the naked eye. Most of the existing detections are carried out by a measuring scale or a level, but this detection method has low detection efficiency and is difficult to meet the production requirements of industrialization. At the same time, it is inconvenient to position the silicon steel sheets during detection, and detection errors are likely to occur.

[0004] Therefore, those skilled in the art have provided a flatness detection device for silicon steel sheets of a DC brushless iron core to solve the problems mentioned in the above prior art. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 , the embodiments provided by the present utility model:

[0024] The embodiment of the present application discloses a device for detecting the flatness of a DC brushless iron core silicon steel sheet, including a mounting plate 1. One side of the top of the mounting plate 1 is fixedly connected by bolts to a fixing plate 2. One side of the fixing plate 2 is fixedly connected by bolts to a top plate 3. A through groove is opened at the top of the top plate 3. A detection mechanism is arranged at the bottom of the top plate 3. The detection mechanism includes a detection component and a moving component. The detection component includes an electronic pressure sensor 4 arranged inside the mounting plate 1 and the top plate 3. A pressing roller 5 is fixedly assembled at the bottom of the electronic pressure sensor 4. A display device 41 that cooperates with the electronic pressure sensor 4 is fixedly assembled on the surface of the fixing plate 2. The moving component is located at the top of the electronic pressure sensor 4. A clamping mechanism is arranged at the middle part of the top of the mounting plate 1.

[0025] As a technical optimization scheme of the present utility model, the display device 41 includes a PLC controller, and the display device 41 is electrically connected to the electronic pressure sensor 4 through a wire. When the pressing roller 5 is in contact with the surface of the silicon steel sheet, the display device 41 will display the pressure value. If the value changes during the rolling process of the pressing roller 5 on the surface of the silicon steel sheet, it can reflect that the surface of the silicon steel sheet is in an uneven state.

[0026] The moving component includes a motor 6 fixedly assembled on one side of the top of the top plate 3. The output shaft of the motor 6 is fixedly connected by a coupling to a lead screw 7. A movable block 8 is threadedly connected to the surface of the lead screw 7. The bottom of the movable block 8 penetrates through the through groove and is fixedly assembled with a lifting component.

[0027] As a technical optimization solution of the present utility model, an internal thread for cooperating with the lead screw 7 is provided in the inner cavity of the movable block 8. Therefore, when the lead screw 7 rotates, it can drive the movable block 8 to move, so that the pressing roller 5 rolls on the surface of the silicon steel sheet.

[0028] The lifting assembly includes an electric push rod 9 fixedly assembled at the bottom of the movable block 8, and the electric push rod 9 is fixedly assembled at the top of the electronic pressure sensor 4.

[0029] As a technical optimization solution of the present utility model, the electric push rod 9 can drive the electronic pressure sensor 4 and the pressing roller 5 to lift and fit on the surface of the silicon steel sheet, and the user can make corresponding adjustments according to the thickness of the silicon steel sheet.

[0030] The clamping mechanism includes a placement table 10 fixedly connected to the middle part of the top of the mounting plate 1 by bolts. L-shaped plates 11 are fixedly connected to the front and back of the top of the mounting plate 1 by bolts. Threaded rods 12 are threadedly connected to the tops of the L-shaped plates 11. Clamping plates 13 are rotatably connected to the bottoms of the threaded rods 12 through bearings. Handles 14 are fixedly connected to the tops of the threaded rods 12 by bolts. A limiting assembly is arranged on the outer side of the clamping plate 13.

[0031] As a technical optimization solution of the present utility model, the handle 14 can increase the contact area of the threaded rod 12, so as to facilitate the user to rotate the threaded rod 12, thereby controlling the clamping plate 13 to fix the silicon steel sheet.

[0032] The limiting assembly includes limiting blocks 15 fixedly connected to both ends of the outer side of the clamping plate 13 by bolts, and limiting grooves 16 for cooperating with the limiting blocks 15 are provided on the inner walls of the L-shaped plates 11.

[0033] As a technical optimization solution of the present utility model, the cooperation of the limiting block 15 and the limiting groove 16 can play a role in limiting and supporting the clamping plate 13, thereby improving the clamping effect of the clamping plate 13.

[0034] Anti-slip pads 17 are bonded to the bottoms of the clamping plates 13, and the thickness of the anti-slip pads 17 is 8MM - 12MM.

[0035] As a technical optimization solution of the present utility model, the anti-slip pad 17 is made of rubber material, which can increase the friction force, thereby preventing the silicon steel sheet from shifting during detection.

[0036] Sliders 18 are fixedly connected to the front and back of the movable block 8 by bolts. Slide rods 19 are slidably connected to the inner cavities of the sliders 18, and the slide rods 19 are fixedly connected to the surface of the fixed plate 2 by bolts.

[0037] As a technical optimization solution of the present utility model, the movable block 8 is limited and supported by the slider 18 and the slide bar 19, so as to ensure that the movable block 8 can move stably under the rotation of the lead screw 7.

[0038] Working principle: The user places the silicon steel sheet on the top of the placement table 10, and then rotates the handle 14 to make the threaded rod 12 rotate, so that the clamping plate 13 moves and fixes the silicon steel sheet, thereby preventing the silicon steel sheet from shifting during detection. Then, the user makes the pressing roller 5 fit on the surface of the silicon steel sheet through the electric push rod 9, and the pressure value is displayed on the display device 41. Then, the user rotates the lead screw 7 through the motor 6, so that the movable block 8 drives the pressing roller 5 to roll on the surface of the silicon steel sheet. At this time, if the pressure value on the display device 41 changes, it can be preliminarily determined that the flatness of the silicon steel sheet is insufficient. Compared with the prior art, the detection efficiency can be improved, and the industrial production requirements can be met.

[0039] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
