Description

Technical Field

[0001] This utility model relates to the field of iron core testing technology, specifically a batch-processable iron core product testing device. Background Technology

[0002] The iron core is the core component of a transformer, and it is generally made up of a large number of silicon steel sheets stacked together. During the operation of the transformer, eddy currents are generated inside the iron core, which leads to a decrease in equipment efficiency. The magnitude of the eddy currents in the iron core is affected by the thickness of the iron core. Therefore, it is necessary to test the stacking thickness of the iron core products to determine the quality of the iron core.

[0003] Traditionally, the thickness of the iron core stack is manually inspected. During manual inspection, the inspection tool needs to be placed against the side of the iron core. However, the silicon steel sheets on the iron core are only stacked. Therefore, during the inspection process, the silicon steel sheets are easily touched and shifted, requiring them to be restored. This results in low inspection efficiency and low accuracy. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of low testing efficiency in existing technologies and to provide a batch testing device for iron core products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a batch-processable iron core product testing device, comprising a base, on which a transverse through slot is formed, and two left-right distributed conveyor rollers are movably connected within the slot, with a conveyor belt fitted around the outer side of the two conveyor rollers. A motor is fixedly connected to the front side of the base, and the output shaft of the motor extends into the slot and is fixedly connected to a transmission wheel. The transmission wheel is intermittently connected to the adjacent conveyor roller. A U-shaped bracket is connected to the top of the base, and the bracket is erected above the slot and perpendicular to the conveyor belt. A positioning plate is provided below the bracket, and a cylinder is fixedly connected to the top of the bracket, with the telescopic end of the cylinder extending to the bottom of the bracket and fixedly connected to the positioning plate. A pressure sensor and an infrared rangefinder are fixedly connected to the positioning plate, with the infrared rangefinder's emission port facing vertically downwards. A display and a controller are fixedly connected to the bottom of the positioning plate and to the front side of the base.

[0006] As described above, a cross-shaped grooved wheel is fixedly connected to one end of the conveying roller near the drive wheel, and the grooved wheel is provided with sliding grooves along the cross direction. A fixed rod is fixedly connected to the drive wheel, and the fixed rod is inserted into the adjacent sliding groove.

[0007] As described above, the positioning plate consists of a fixed plate and a movable plate. The fixed plate is fixedly connected to the telescopic end of the cylinder. A groove is provided at the bottom of the fixed plate, and the movable plate is located in the groove. A spring is fixedly connected between the movable plate and the fixed plate.

[0008] As described above, the pressure sensor is fixedly connected to the inner wall of the top of the fixed plate, the infrared rangefinder is embedded in the movable plate and located at the end, and the emission port of the infrared rangefinder is flush with the bottom surface of the movable plate.

[0009] As described above, linear guide rails are fixedly connected to the inner walls of both the front and rear sides of the bracket, and sliders are slidably connected to the linear guide rails. The two ends of the fixed plate are fixedly connected to the adjacent sliders.

[0010] As described above, the top of the fixed plate has two openings, and a T-shaped limiting rod is inserted into each of the two openings. The limiting rod is fixedly connected to the movable plate.

[0011] Compared with existing technologies, this batch-processing iron core product testing device has the following advantages: This utility model uses a conveyor belt to transport iron cores, and a cylinder pushes a positioning plate to contact the iron core from above for calibration. Then, an infrared rangefinder is used for measurement, thereby realizing the automatic detection of the stacked thickness of the iron cores. During this process, only the iron cores are subjected to pressure from top to bottom, thus avoiding the displacement of silicon steel sheets and improving the efficiency and accuracy of product testing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution for a batch-processable iron core product testing device: A batch-processable iron core product testing device includes a base 1, on which a transverse through slot is opened. Two left and right distributed conveyor rollers 7 are movably connected in the slot, and a conveyor belt 2 is sleeved on the outside of the two conveyor rollers 7. A motor 5 is fixedly connected to the front side of the base 1, and the output shaft of the motor 5 extends into the slot and is fixedly connected to a transmission wheel 9. The transmission wheel 9 is intermittently connected to the adjacent conveyor roller 7. A gate-shaped bracket 3 is connected to the top of the base 1. The bracket 3 is mounted above the slot and is perpendicular to the conveyor belt 2. A positioning plate is provided below the bracket 3. A cylinder 4 is fixedly connected to the top of the bracket 3, and the telescopic end of the cylinder 4 extends to the bottom of the bracket 3 and is fixedly connected to the positioning plate. A pressure sensor 10 and an infrared rangefinder 18 are fixedly connected to the positioning plate, and the emission port of the infrared rangefinder 18 faces vertically downward. A display 6 and a controller 16 are fixedly connected to the bottom of the positioning plate and to the front side of the base 1.

[0020] According to the overall structure of the device, when in use, the device is connected to an external power source, and the iron core product is transported onto the conveyor belt 2. The motor 5 is started, and the motor 5 drives the transmission wheel 9 to rotate, which in turn drives the conveyor roller 7 to rotate intermittently, thereby conveying the iron core product to the bottom of the positioning plate. Then, the cylinder 4 is started, and the cylinder 4 pushes the positioning plate down, so that the positioning plate abuts against the top surface of the iron core. At this time, pressure is generated between the positioning plate and the iron core, and the pressure sensor 10 generates a sensing signal that is fed back to the controller 16. Then, the controller 16 starts the infrared rangefinder 18 to detect the height of the iron core, thereby obtaining the iron core stacking thickness data, which is displayed on the display 6 for easy recording.

[0021] like Figure 2 As shown, a cross-shaped grooved wheel 8 is fixedly connected to one end of the conveyor roller 7 near the drive wheel 9, and grooves are provided on the grooved wheel 8 along the cross direction. A fixing rod 15 is fixedly connected to the drive wheel 9, and the fixing rod 15 is inserted into the adjacent groove.

[0022] The transmission wheel 9 is driven by motor 5 to rotate, which in turn drives the fixed rod 15 to rotate. The rotation of the fixed rod 15 causes the groove wheel 8 to rotate intermittently through the chute, which in turn drives the conveyor belt 2 to move intermittently, transporting the iron core product to the bottom of the positioning plate for testing.

[0023] like Figure 2 , 3 As shown, the positioning plate consists of a fixed plate 13 and a movable plate 12. The fixed plate 13 is fixedly connected to the telescopic end of the cylinder 4. A groove is provided at the bottom of the fixed plate 13, and the movable plate 12 is located in the groove. A spring 11 is fixedly connected between the movable plate 12 and the fixed plate 13. The pressure sensor 10 is fixedly connected to the inner wall of the top of the fixed plate 13. The infrared rangefinder 18 is embedded in the movable plate 12 and located at the end. The emission port of the infrared rangefinder 18 is flush with the bottom surface of the movable plate 12.

[0024] The positioning plate is formed by the fixed plate 13, the movable plate 12 and the spring 11. When the cylinder 4 pushes the positioning plate down, the movable plate 12 first contacts the iron core. The groove at the bottom of the fixed plate 13 and the spring 11 provide a buffer space for the movable plate 12 to contact the iron core, preventing excessive pressure on the iron core and damage. By making the emitter of the infrared rangefinder 18 flush with the bottom surface of the movable plate 12, the emitter of the infrared rangefinder 18 is made flush with the top surface of the iron core, improving the measurement accuracy.

[0025] like Figure 3 As shown, linear guide rails 17 are fixedly connected to the inner walls of the front and rear sides of the bracket 3, and sliders are slidably connected to the linear guide rails 17. The two ends of the fixing plate 13 are fixedly connected to the adjacent sliders.

[0026] The linear guide 17 limits the lifting and lowering of the fixed plate 13 to prevent the fixed plate 13 from shifting, and the linear guide 17 facilitates the smooth lifting and lowering of the movable plate 12.

[0027] like Figure 4 As shown, the top of the fixed plate 13 has two openings, and a T-shaped limiting rod 14 is inserted into each of the two openings. The limiting rod 14 is fixedly connected to the movable plate 12.

[0028] The movable plate 12 and the fixed plate 13 are connected by the limiting rod 14 to prevent the movable plate 12 from falling off the limiting plate.

[0029] Working principle: When in use, connect the device to an external power source and transport the iron core product onto the conveyor belt 2. Start the motor 5 to intermittently transport the product to the bottom of the positioning plate. Then, start the cylinder 4, which pushes the positioning plate down so that the movable plate 12 abuts against the top surface of the iron core and compresses the spring 11. This causes the movable plate 12 to press against the pressure sensor 10. The pressure sensor 10 generates a sensing signal that is fed back to the controller 16. Then, the controller 16 starts the infrared rangefinder 18 to detect the height of the iron core, thereby obtaining the stacking thickness data of the iron core, which is displayed on the display 6 for easy recording.
