Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, in particular to a flapping electromagnet. Background Art

[0002] The flapping electromagnet is composed of three parts: a coil, an iron core, and a terminal. The iron core can concentrate the magnetic field of the coil, enhance the magnetic field strength and magnetic effect. The coil winds multiple turns of wire around the iron core and is energized to generate a magnetic field through the current. When the current is passed into the coil, the charges on the coil start to move and are subjected to forces, and the coil generates a magnetic field. The iron core will concentrate the magnetic field together to form a stronger magnetic field. At this time, the iron block on the iron core will be attracted by the electromagnetic force, enabling the operation of the electromagnet, which is applicable to occasions such as controlling conveyor belts, grippers, disk drives, electromagnetic guns, electromagnetic locks, etc. that require a strong magnetic effect.

[0003] However, in the prior art, most of the support points of the flapping rod of the flapping electromagnet are fixed. During use, only the top limit point can be adjusted to control the flapping rotation angle, but the distance between the flapping rod and the iron core cannot be adjusted, resulting in inconvenience in adjusting the position and movement range of the flapping rod during flapping when in use, and reducing the applicable range of the flapping electromagnet in practical applications. Summary of the Utility Model

A first screw rod is fixed to the outside of each slider, and a first clamping block is threadedly sleeved on one end of the first screw rod extending to the outside of the supporting side plate. Both the two sliders and the first screw rods are slidably connected inside an upper adjustment groove formed in the upper part of the supporting side plate.

[0010] Preferably, a second screw rod is fixed to one side of the lower connecting plate close to the supporting side plate, and the second screw rod is slidably inserted into a lower adjustment groove formed in the lower part of the supporting side plate.

[0026] As Figures 1-4As shown in the figure, the present utility model provides a flapping electromagnet, which includes an electromagnet coil 1, an electromagnet housing 2 and an iron core 3. A flapping rod 4 is arranged above the iron core 3. A supporting side plate 5 is fixed to the side of the electromagnet housing 2. The flapping rod 4 is rotatably connected inside the supporting side plate 5. One end of the flapping rod 4 passing through to the outside of the supporting side plate 5 is fixed with a spring 12 at the bottom surface, and a lower connecting plate 10 is fixed to the bottom surface of the spring 12. A guide rod 11 is fixed to the top surface of the lower connecting plate 10, and the guide rod 11 is slidably inserted inside the spring 12. Both the flapping rod 4 and the lower connecting plate 10 are adjustably connected to the supporting side plate 5. A fixing plate 6 is fixed to the side surface of the supporting side plate 5 above the flapping rod 4, and an adjusting screw 7 is threadedly sleeved at one end of the fixing plate 6 away from the supporting side plate 5. A limiting ball 9 is fixed to one end of the adjusting screw 7 passing through to the lower part of the fixing plate 6.

[0027] The following specifically describes the specific settings and functions of this embodiment: A protective cover 20 is sleeved outside the flapping rod 4 and the limiting ball 9 for protecting the iron core 3 and the flapping rod 4. The protective cover 20 is detachably fixed to the top surface of the electromagnet housing 2 to protect the iron core 3 and the flapping rod 4. Positioning fixing blocks 21 are fixed to the middle parts of the lower sides of both side surfaces of the protective cover 20, and another positioning fixing block 21 is fixed to the top surface of the electromagnet housing 2 on both sides of the positioning fixing block 21 for limiting the positioning fixing block 21 on the protective cover 20 to ensure that the protective cover 20 can be aligned and installed on the top surface of the electromagnet housing 2 and is convenient for detachable fixing. The positioning fixing blocks 21 on the electromagnet housing 2 and the protective cover 20 are fixed by bolts. An insertion hole is opened at the lower part of one side of the protective cover 20 away from the supporting side plate 5. Threaded holes matching with the bolts are opened inside each positioning fixing block 21. A connecting head 8 is fixed to the top surface of the end of the flapping rod 4 away from the supporting side plate 5 for connecting the movable end. The length of the flapping rod 4 is greater than the maximum length between the supporting side plate 5 and the iron core 3 to ensure that after the flapping rod 4 is adjusted, it can still fall on the iron core 3 after the electromagnet housing 2 is powered on.

[0028] Embodiment 2

[0029] As Figures 1-4 shown, rotating shafts 13 are fixed to both ends of the flapping rod 4 extending into the supporting side plate 5, and sliding blocks 14 are rotatably sleeved on the rotating shafts 13. A screw rod one 15 is fixed to the outside of each sliding block 14, and a clamping block one 16 is threadedly sleeved at one end of the screw rod one 15 extending to the outside of the supporting side plate 5. The two sliding blocks 14 and the screw rod one 15 are all slidably connected inside an upper adjusting groove 17 opened at the upper part of the supporting side plate 5. A screw rod two 18 is fixed to one side of the lower connecting plate 10 close to the supporting side plate 5, and the screw rod two 18 is slidably inserted inside a lower adjusting groove 22 opened at the lower part of the supporting side plate 5. A clamping block two 19 is threadedly sleeved at one end of the screw rod two 18 extending to the outside of the supporting side plate 5.

[0030] The effect achieved by the entire embodiment is that the lower connecting plate 10 is set in an inverted "L" shape, and the widths of the lower connecting plate 10 and the second clamping block 19 are both greater than the width from the lower adjusting groove 22, which facilitates the cooperation between the lower connecting plate 10 and the second clamping block 19 to clamp and fix the supporting side plate 5. The second screw 18 is set in a horizontally placed "T" shape to prevent the second clamping block 19 from separating from the second screw 18. Each slider 14 is set in a horizontally placed "convex" shape, so that the slider 14 can cooperate with the first clamping block 16 to clamp the side of the supporting side plate 5. A rotating hole for cooperating with the rotating shaft 13 is provided inside each slider 14. The two first screws 15 are set in a horizontally placed "T" shape to prevent the first clamping block 16 from separating from the first screw 15.

[0031] The usage method and working principle of this device: When an electromagnet is needed, first adjust the position of the beating rod 4 according to the usage requirements. During adjustment, turn the two first clamping blocks 16 to release the clamping and fixing of the supporting side plate 5 by the first clamping blocks 16, and then the beating rod 4 can be pulled up and down to adjust the distance between the beating rod 4 and the iron core 3. During adjustment, turn the lower second clamping block 19, and the clamping and fixing of the supporting side plate 5 by the second clamping block 19 can be released, and then the lower connecting plate 10 can be driven to move accordingly. After adjusting the position of the beating rod 4, turn the two first clamping blocks 16 to make the first clamping blocks 16 clamp and fix the supporting side plate 5 again. Then pull the lower connecting plate 10 to adjust the tensile strength of the spring 12. After adjustment, turn the second clamping block 19 to clamp and fix the supporting side plate 5 again. Turn the adjusting screw 7 to drive the limiting ball 9 to move up and down, and the rotatable range of the beating rod 4 during beating can be controlled. When connecting the movable end, screw the movable end into the connecting head 8 for fixation and pass through the insertion hole. Finally, align the positioning and fixing blocks 21 on both sides of the protective cover 20 and snap them into the positioning and fixing blocks 21 on the top surface of the electromagnet housing 2, and fix them with bolts.
