Description

Technical Field

[0001] The utility model relates to the technical field of magnetic material production devices, in particular to a magnetic steel magnetic flux detection device. Background Art

[0002] Magnets are made of several hard and strong metals, such as iron, aluminum, nickel, cobalt, etc., and sometimes copper, niobium, and tantalum. They are used to make super-hard permanent magnet alloys. The metal components are different, the magnetic properties are different, and the uses are also different. The magnetic flux is a physical quantity that describes the distribution of the magnetic field. The magnetic flux is the magnetic strength of the magnet. Then, through the magnetic flux detection device, the size of the magnetic flux can be achieved, that is, the magnetic size of the magnet can be understood, so that the use of the magnet can be known.

[0003] Generally speaking, objects with magnetism can have electromagnetic induction, and electromagnetic induction means that a conductor placed in a changing magnetic flux will generate an electromotive force. This is the result of electromagnetic induction, so the magnetic flux can be detected.

[0004] Chinese patent authorization announcement number: CN217007647U, authorization announcement date July 19, 2022, discloses a permanent magnet magnetic flux detection device, including: a base, the support feet at the bottom of which are placed horizontally on the ground, and an instrument body for displaying the magnetic flux value is fixedly installed on the upper surface of the base, and a socket is fixedly embedded on the base, and the top of the socket and the upper surface of the base are located in the same plane; it also includes: an outer cylinder, which is vertically attached to the top of the base, and the bottom of the outer cylinder is fixedly penetrated with symmetrically distributed connecting terminals, and the two connecting terminals are respectively slidably inserted in the connecting holes of the socket, and the socket is connected to the instrument body through a wire; a guide frame, which is symmetrically attached to both sides of the outer cylinder, the bottom end of the guide frame is vertically installed on the top of the base, and the inner sides of the two guide frames are respectively attached with vertical guide blocks, and the guide blocks are fixedly installed on the side walls of the outer cylinder. The shortcoming of this technical solution is that when performing magnetic flux detection, the permanent magnet is directly placed in the placement slot on the top of the outer cylinder and is left stationary. In this way, the magnetic flux induced by electromagnetic induction will be a fixed value. Since the induction of magnetic flux will be affected by the thickness of the magnetic steel, the width of the magnetic steel, and the size of the chamfer of the magnetic steel, the numerical value obtained in this way is more comprehensive.

[0005] In summary, the detection can be performed while the magnet is rotating to meet the condition of a conductor placed in a changing magnetic flux, so that the detection result of the magnetic flux is more comprehensive. Utility Model Content

[0027] First, place the outer cylinder 3 and the instrument body 2 on the top surface of the supporting plate 1. The instrument body 2 here can be connected to the top surface of the supporting plate 1 by using screws and screw holes. Of course, the top surface of the supporting plate 1 must be provided with screw grooves, and the instrument body 2 is provided with screw holes, so that the screws can be controlled to pass through the screw holes and be threadedly connected with the screw grooves on the supporting plate 1. The connection between the outer cylinder 3 and the supporting plate 1 requires the cooperation of the guide frame 13 and the guide block 14. Here, the plurality of guide frames 13 on the top surface of the support plate 1 correspond to the plurality of guide blocks 14 installed on the outer cylinder 3, and the plurality of guide blocks 14 are symmetrically distributed with the outer cylinder 3 as the center. Therefore, when controlling the outer cylinder 3, the guide blocks 14 can be inserted into the slots 12 on the guide frames 13 corresponding to the positions thereof. The slots 12 are provided with through holes 10, and the storage cylinders 6 are installed at the through holes 10. The storage cylinders 6 are connected with the slots 12 through the through holes 10. A pull rod 7 is installed in the storage cylinder 6, and a card block 11 is installed at the front end of the pull rod 7. The card block 11 matches the card slot on the guide block 14. The rear end of the pull rod 7 is installed with the force plate 5, and the limiting disc 9 and spring 8 mounted on the pull rod 7 are placed between the block 11 and the force plate 5. Not only that, the diameter of the limiting disc 9 is larger than the diameter of the through hole 10, and the limiting disc 9 is connected to the storage tube 6 through the spring 8. In this way, controlling the force plate 5 is to push the pull rod 7, that is, to push the block 11, until the block 11 is inserted into the slot, and with the elastic effect of the spring 8, the block 11 is stably limited in the slot. In other words, this is the control operation, and the work of installing the outer tube 3 on the supporting plate 1 is performed. Not only that, the socket 19 is also placed on the supporting plate 1, and the induction coil 16 on the outer cylinder 3 is electrically connected to 18, so the electrical connection with the socket 19 can be done naturally. By connecting the wire 17, it is electrically connected to the single-chip microcomputer of the instrument body 2. The single-chip microcomputer is naturally electrically connected to the instrument body 2. In this way, the installation of the instrument body 2, the outer cylinder 3 and the supporting plate 1 is completed, that is, the magnetic flux detection of the magnet can be carried out.

[0028] Next, pay attention to the structural shape of the magnetic steel, and then put the magnetic steel into the slot through the slot of the storage slot 4 on the outer cylinder 3. The slot is placed at the top of the outer cylinder 3, and the bottom of the slot is placed at the bottom of the outer cylinder 3, which prevents the magnetic steel from escaping from the storage slot 4, thereby smoothly carrying out the magnetic flux detection work.

[0029] After the magnet is placed, the induction coil 16 in the storage slot 4 is immediately sensed, thereby performing electromagnetic induction. The induction coil 16 here is placed at the top of the support column 15, and a number of sockets need to be placed between the induction coil 16 and the slot, so that the insertion rod 20 at the socket can be controlled to limit the magnet, and the magnetic flux detection work can be carried out smoothly.

[0030] The plug rod 20 is installed at the jack, and the front end of the plug rod 20 is installed with a connecting block 26.

The rear end of the plug rod 20 passes through the jack and is placed at the outer end of the outer cylinder 3, and is installed with a limit plate 21. Then, the soft clamping block 23 connected to the plug rod 20 can be moved by the control of the limit plate 21. Of course, the diameter of the limit plate 21 is larger than the diameter of the jack, which can prevent the plug rod 20 from being completely inserted into the storage slot 4, thereby affecting the detection of the magnetic flux of the magnetic steel. The soft clamping blocks 23 corresponding to the position here all move toward the magnetic steel, which can clamp the magnetic steel, and under the elastic effect of the compression spring 25, the elastic effect of the soft clamping block 23, no matter what shape the magnetic steel is, it can be stably limited, so as to detect the magnetic flux.

[0031] Next, the magnetic steel needs to be rotated, so that the electromagnetic induction can produce different results due to the different factors such as the magnetic steel thickness, magnetic steel width and magnetic steel chamfer size. The limit plate 21 here can rotate the soft clamp 23, that is, the magnetic steel is rotated, and the result obtained in this way is to make the magnetic flux detection result more comprehensive. In order to facilitate the smooth rotation of the plug rod 20, a rolling bearing can be installed at the jack, so that the plug rod 20 is connected to the inner ring of the rolling bearing, and the outer ring of the rolling bearing is connected to the outer cylinder. In this way, the magnetic flux detection performed by the rotation of the magnetic steel achieves the purpose of installing a device that can drive the magnetic steel to rotate for detection.

[0032] It should be noted that the operation of the meter body 2 here requires the power supply electrically connected to the switch to be provided with electricity, that is, the meter body 2 needs to be electrically connected to the switch.

[0033] The support plate 1, the outer cylinder 3, the support column 15, the plug rod 20, the hard clamp block 24 and the connection hard block 26 are all made of hard plastic materials that can be insulators, which is not only convenient for operation to complete the magnetic flux detection of the magnetic steel, but also the insulation will not have an adverse effect on the detection work. The soft clamp block 23 can be made of soft rubber, which not only has good insulation, but also is convenient for clamping and limiting magnetic steels of various shapes.
