Description

Technical Field

[0001] The invention relates to the technical field of electromagnet detection, and in particular to an electromagnet suction detection device used in electromagnet production. Background Art

[0002] Before, an electromagnet is a device that generates electromagnetism when electricity is supplied. A conductive winding matching its power is wound around the outside of the iron core. This coil with current flowing through it has magnetism like a magnet. It is also called an electromagnet. In the process of measuring the performance of an electromagnet, the suction value of the electromagnet needs to be measured.

[0003] During measurement, the electromagnet is energized and the iron block is adsorbed on the electromagnet. Then, the traction measuring mechanism applies a separation force to the iron block to overcome the electromagnetic suction force so as to separate the iron block from the electromagnet. The suction force is measured by the pressure (tension) sensor. However, during measurement, only the sensor data can be read by the computer, and it is impossible to intuitively judge whether the electromagnet suction force is qualified.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 4 The present invention provides an electromagnet suction force detection device for electromagnet production, comprising:

[0033] A load-bearing frame, a balancing base 23 is installed at the bottom of the load-bearing frame;

[0034] A fixing frame 1, wherein the fixing frame 1 is fixed on the top of the supporting frame;

[0035] A force-applying frame, which is vertically slidably connected to the fixed frame 1, on which a linear loading assembly is mounted, and the top of the linear loading assembly is fixedly connected to the top of the force-applying frame;

[0036] The equivalent force detection mechanism includes a pressure-resistant cylinder 2 fixedly connected to the bottom of the force-applying frame, a pull rod 3 is vertically slidably connected to the bottom of the pressure-resistant cylinder 2, a piston 4 is fixedly connected to one end of the pull rod 3 located in the pressure-resistant cylinder 2, a connecting block 25 is fixedly connected to the bottom end of the pull rod 3, a pressure-stabilizing assembly is arranged at the top of the pressure-resistant cylinder 2, and a buffer assembly is installed on the top wall inside the pressure-resistant cylinder 2;

[0037] A fixing fixture, the fixing fixture is fixed to the bottom of the supporting frame, the electromagnet is fixed to the fixing fixture, and the electromagnet is magnetically connected to the connecting block 25;

[0038] A gas pressure sensor is installed in the pressure-resistant cylinder 2 , and the gas pressure sensor is located between the piston 4 and the bottom of the pressure-resistant cylinder 2 . The gas pressure sensor is electrically connected to the terminal controller.

[0039] The controller can be set according to the specific use environment, for example, it can be a single chip microcomputer or controlled by PLC, ARM (Advanced RISC Machine: high-end reduced instruction set machine), FPGA (Field-Programmable Gate Array: Field Programmable Gate Array) and other methods, which are not specifically limited in this embodiment;

[0040] When the present invention is working, the electromagnet is fixed to the bottom of the supporting frame by a fixing clamp, and the linear loading component horizontally controls the force frame to descend, and the force frame drives the pressure-resistant cylinder 2 to descend, and the connecting block 25 at the bottom of the pressure-resistant cylinder 2 is magnetically attracted to the magnet. At this time, air is inflated between the piston 4 and the bottom of the pressure-resistant cylinder 2. When the pressure reaches a certain threshold, it stops, and the linear loading component applies a loading force in a linear direction to pull the pressure-resistant cylinder 2 upward, and a relative movement is generated between the pressure-resistant cylinder 2 and the piston 4, thereby compressing the internal gas. The change in the internal gas is detected by a gas pressure sensor, and the value is transmitted to the terminal controller. The terminal controller summarizes the data and forms a pressure change curve until the electromagnet is separated from the connecting block 25, and the suction force detection is completed.

[0041] The present invention obtains the suction value through the change of gas pressure in the pressure-resistant cylinder 2. When the electromagnet is separated from the connecting block 25, the gas pressure value in the pressure-resistant cylinder 2 is the maximum suction value, so that the suction of the electromagnet can be intuitively obtained.

[0042] A further optimized solution is that the supporting frame includes a top plate 5 and a bottom plate 6, a plurality of screws 7 are fixedly connected between the top plate 5 and the bottom plate 6, the screws 7 are vertically arranged between the top plate 5 and the bottom plate 6, a balancing base 23 is fixedly connected to the bottom end of the screw 7, a spacer is arranged between the top plate 5 and the bottom plate 6, and the fixing frame 1 is fixedly connected to the top surface of the top plate 5.

[0043] A further optimized solution is that the force frame includes an upper pad 8 and a lower pad 9. The upper pad 8 is located above the fixed frame 1, and the lower pad 9 is located below the top plate 5. A plurality of sliding rods 10 are fixedly connected between the upper pad 8 and the lower pad 9. The sliding rods 10 pass through the top plate 5 and are slidably connected to the top plate 5. The pressure-resistant cylinder 2 is fixed to the bottom surface of the lower pad 9.

[0044] The upper pad 8 and the lower pad 9 are respectively located on the upper and lower sides of the top plate 5. The cooperation between the upper pad 8, the lower pad 9 and the slide rod 10 can enable the entire force frame to slide vertically to ensure the stability of the force, while increasing the load and avoiding damage to the device.

[0045] In a further optimized solution, the linear loading assembly includes a hydraulic cylinder 11 fixedly connected to the fixed frame 1, and the top of the hydraulic cylinder 11 is fixedly connected to the bottom surface of the upper pad 8. The loading in the linear direction is achieved by the hydraulic cylinder 11 to ensure the stability of the loading.

[0046] A further optimized solution is provided, in which the fixing fixture comprises a three-claw bracket 12, and a support platform 13 is fixedly connected to the bottom of the middle position of the three-claw bracket 12, and the support platform 13 is fixedly connected to the top surface of the base plate 6, and a mounting groove is opened in the middle of the bottom surface of the base plate 6, and a mounting platform 14 is vertically slidably connected in the mounting groove, and the support platform 13 and the mounting platform 14 are coaxially arranged, and a hydraulic push rod 15 is fixedly connected to the bottom surface of the support platform 13, and the bottom end of the hydraulic push rod 15 is fixedly connected to the mounting platform 14, and the three ends of the three-claw bracket 12 are respectively rotatably connected to the clamping assembly, and the bottom surface of the clamping assembly is respectively rotatably connected to the support arm 16, and the end of the support arm 16 is rotatably connected to the support rod 17, and the support rod 17 passes through the mounting groove and is rotatably connected to the top surface of the mounting platform 14, and an angle is set between the axis of the support rod 17 and the top surface of the mounting platform 14.

[0047] The mounting platform 14 is pushed downward by the hydraulic push rod 15, and the mounting platform 14 drives the support rod 17 and the support arm 16 to move. The bidirectional hydraulic telescopic rod 18 is pushed inward by the support arm 16, and the positioning rod 19 contacts the outer wall of the electromagnet and positions the electromagnet through the positioning notch 20 to ensure the stability of the positioning.

[0048] A further optimized solution is that the clamping assembly includes a bidirectional hydraulic telescopic rod 18 rotatably connected to the end of the three-claw bracket 12, the support arm 16 is rotatably connected to the bottom of the bidirectional hydraulic telescopic rod 18, and the two ends of the bidirectional hydraulic telescopic rod 18 are respectively fixedly connected with positioning rods 19, and a positioning notch 20 is provided on the side surface of the top end of the positioning rod 19, and the positioning notch 20 is clamped with the top edge of the electromagnet.

[0049] In this embodiment, the relative position of the positioning rod 19 is controlled by the bidirectional hydraulic telescopic rod 18, so that different positions of the edge of the magnet can be positioned to ensure that the electromagnet can be fixed on the fixture.

[0050] According to a further optimized solution, the pressure stabilizing assembly includes a pressure stabilizing valve 21. An air hole is provided at the top of the pressure-resistant cylinder 2, and the pressure stabilizing valve 21 is installed in the air hole.

[0051] According to a further optimized solution, the buffer assembly includes a buffer airbag 22 fixedly connected to the pressure-resistant cylinder 2 , and the buffer airbag 22 is arranged corresponding to the piston 4 .

[0052] When the suction limit is reached, the connecting block 25 and the electromagnet will separate. At the same time, due to the high gas pressure in the pressure-resistant cylinder 2, a large instantaneous reverse thrust will be generated on the piston 4. Therefore, a buffer airbag 22 is provided to avoid damage to the piston 4. At the same time, the pressure-stabilizing valve 21 needs to set a pressure threshold, so that during the reverse extrusion of the piston 4, a certain gas buffering effect will be formed between the top of the piston 4 and the top of the pressure-resistant cavity, thereby preventing the piston 4 from directly hitting the top of the pressure-resistant cylinder 2 and causing damage.

[0053] According to a further optimization scheme, a vertical sliding hole is provided at the bottom end of the pressure-resistant cylinder body 2, the pull rod 3 is slidably connected in the sliding hole, a sealing rubber ring 24 is provided between the outer wall of the pull rod 3 and the sliding hole, and the sealing rubber ring 24 is fixed on the inner wall of the sliding hole.

[0054] In the present embodiment, the provision of the sealing rubber ring 24 can ensure the sealing property inside the pressure-resistant cylinder 2. It should be noted that, in the actual working process, friction will be generated between the pull rod 3 and the sealing rubber ring 24 and between the piston 4 and the inner wall of the pressure-resistant cylinder 2. Therefore, in the present embodiment, it is necessary to use a sealing rubber ring 24 with a known friction coefficient to slide relative to the pressure-resistant cylinder 2 and the pull rod 3. In this way, the friction force can be calculated, and then the gas pressure value inside the pressure-resistant cylinder 2 and the friction force are added together to calculate the actual suction value.

[0055] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0056] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
