Description

Technical Field

[0001] The invention relates to the technical field of ferrite detection equipment, and in particular to a strength detection equipment for embedded simulated injection molding of ferrite magnetic rings. Background Art

[0002] Ferrite rings are parts that can suppress electromagnetic interference, mainly including nickel-zinc ferrite rings and manganese-zinc ferrite rings. These two types of rings have strict distinctions for using different frequencies. Nickel-zinc ferrite rings are suitable for suppressing electromagnetic interference in high-frequency bands; manganese-zinc ferrite rings are suitable for suppressing electromagnetic interference in low-frequency bands.

[0003] At present, the higher the magnetic permeability of ferrite, the greater the impedance at low frequency and the smaller the impedance at high frequency. Different processes can be selected to manufacture magnetic rings according to different requirements. Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, and the impedance of the magnetic ring increases sharply when the signal frequency increases.

[0004] However, current ferrite magnetic ring finished products often need to be injection-molded with compatible plastic accessories inside the ferrite magnetic ring to facilitate the use of the ferrite magnetic ring finished products. However, the pressure intensity during injection molding can easily affect the ferrite magnetic ring finished products. Excessive pressure can easily cause the ferrite magnetic ring finished products to break, which is not conducive to the normal use of the ferrite magnetic ring finished products.

[0031] Specifically, by providing a simulated injection molding component, when in use, the device is moved to the interior of the ferrite magnetic ring product through a moving mechanism, and a water flow delivery system is provided, and the water flow for simulating injection molding enters the delivery pipe 4 through the water inlet pipe 18, and then enters the water bag 5 through the connecting pipe 19, so that the water bag 5 squeezes the inner wall of the ferrite magnetic ring product, thereby simulating the pressure during injection molding. At the same time, a detection mechanism is used to detect the inner wall of the ferrite magnetic ring product, so as to determine the damage of the inner wall of the ferrite magnetic ring product. The use is very simple and convenient, and there is no need to experiment the ferrite magnetic ring product through special injection molding, thereby improving the detection efficiency.

[0032] In this embodiment, the moving mechanism includes a connecting block 2, a reinforcement rod, a mounting ring 3, a mounting cylinder 6, a roller 7, a base 8, a fixed block 1 9, a fixed block 2 10, a clamping block 13, a telescopic rod 12, a spring 11, a clamping block 13, a spring 2 14, a stretching rod 15 and a clamping ball 16.

The spring 11 is movably arranged on the mounting cylinder 6. The inside of the tube 6, and one end of the telescopic rod 12 located inside the installation tube 6 is clamped with a spring 11, the other end of the connecting rod 17 is fixedly connected to the reinforcement rod, the fixed block 19 and the fixed block 2 are respectively fixedly installed on the outer walls of both sides of the base 8, the two ends of the roller 7 are respectively movably inserted into the inside of the two side walls of the base 8, the inside of the fixed block 2 10 is provided with a through groove, one end of the stretching rod 15 is fixedly connected to the clamping block 13, the stretching rod 15 is movably inserted into the inside of the fixed block 19 and the fixed block, the other end of the stretching rod 15 is fixedly connected to the clamping ball 16, the spring 2 14 is movably sleeved on the outside of the stretching rod 15, and the spring 2 14 is located on the inner side of the fixed block 19 and the fixed block 2 10.

[0033] Specifically, when in use, the mounting rod 1 is pushed, so that the roller 7 extends into the interior of the finished ferrite magnetic ring, and then the telescopic rod 12, under the action of the spring, makes the roller 7 contact with the inner wall of the finished ferrite magnetic ring, so that it is convenient for it to roll and move inside the finished ferrite magnetic ring, so that the mounting rod 1 is used in the center, which is beneficial for the simulated injection molding component to detect the interior of the finished ferrite magnetic ring, and the force is more uniform. At the same time, when it needs to be fixed, the clamping block 13 can be rotated, so that the stretching rod 15 drives the clamping ball 16 to clamp with the inner wall of the finished ferrite magnetic ring under the action of the spring 14, so that the device can stay stably in the finished ferrite magnetic ring, thereby making the use of the simulated injection molding component more stable.

[0034] The detection mechanism includes a motor 24, a rotating shaft 25, an eccentric wheel 26, a limiting ring 27, a connecting column 28, a telescopic column 29, a detection probe 30, a limiting plate 31 and a spring three 32. One end of the motor 24 and the connecting column 28 are both fixedly connected to the fixed plate two 22, the output end of the motor 24 is fixedly connected to the rotating shaft 25, the eccentric wheel 26 is fixedly connected to the other end of the rotating shaft 25, the other end of the connecting column 28 is fixedly connected to the limiting ring 27, the telescopic column 29 is movably inserted into the interior of the limiting ring 27, one end of the telescopic column 29 is fixedly connected to the detection probe 30, and the other end of the telescopic column 29 is fixedly connected to the limiting round block, the spring three 32 is movably sleeved on the outside of the telescopic column 29 and is located between the limiting round block and the limiting ring 27, and the limiting plate 31 is fixedly sleeved on the outside of the telescopic column 29 and is located on the outside of the limiting ring 27.

[0035] Specifically, the device has an external power supply that provides electrical energy for the device, and an external controller is connected to the device. The controller is electrically connected to the water flow conveying system, the motor 24, and the detection probe 30. When in use, the switch of the motor 24 is turned on, so that the rotating shaft 25 drives the eccentric wheel 26 to rotate, and then the eccentric wheel 26 can push the telescopic rod 12 to extend and move outward, so that the detection probe 30 contacts the inside of the ferrite magnetic ring product, thereby detecting the inner wall of the ferrite magnetic ring product. The detection probe 30 can use a probe detector (profilometer), so that it can be used to detect the simulated part of the simulated injection molding component.

[0036] In summary, compared with the prior art, the ferrite magnetic ring embedded simulated injection molding strength detection equipment has at least the following beneficial effects: by providing a simulated injection molding component, when in use, the device is moved to the inside of the ferrite magnetic ring finished product by a moving mechanism, and a water flow delivery system is provided, and the water flow for simulating injection molding enters the delivery pipe 4 through the water inlet pipe 18, and then enters the water bag 5 through the connecting pipe 19, so that the water bag 5 squeezes the inner wall of the ferrite magnetic ring finished product, thereby simulating the pressure during injection molding. At the same time, a detection mechanism is used to detect the inner wall of the ferrite magnetic ring finished product, so as to determine the damage of the inner wall of the ferrite magnetic ring finished product. It is very simple and convenient to use, and there is no need to experiment on the ferrite magnetic ring finished product through special injection molding, thereby improving the detection efficiency. When not in use, the water flow can be recovered, and the use efficiency is high.
