Description

Technical Field

[0001] The present application relates to the technical field of magnetic steel performance detection, and in particular to a magnetic steel performance detection device. Background Art

[0002] Magnets generally refer to aluminum-nickel-cobalt alloys. 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 magnetic alloys, which are mainly used in various sensors, instruments, electronics, electromechanical, medical, teaching, automobiles, aviation, military technology and other fields. Alnico magnets are the oldest type of magnets and are known as natural magnets. Although it is the oldest, its excellent adaptability to high temperatures makes it still one of the most important magnets.

[0003] With the development of society, the application of magnets is becoming more and more extensive, from high-tech products to the simplest packaging magnets. Currently, the most widely used are neodymium iron boron strong magnets and ferrite magnets. Components made of magnetic steel need to be tested for their magnetism. The current testing method mostly uses the tensile force that can be withstood during adsorption for testing. During the test, a handheld tensile tester is required for testing. During the test, the tester is prone to tilt, resulting in inconvenience in testing. For this reason, we propose a magnetic steel performance testing device. Utility Model Content

[0004] The purpose of the present invention is to provide a magnetic steel performance detection device to solve the problems raised in the above background technology.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] The cam is secured to the upper edge of the chassis and is secured to a central position within the chassis by a secure coupling between the cam and the chassis.

[0007] Preferably, two sliding openings are provided on the upper surface of the support plate, and two sliding rods are fixedly connected to the outer surface of the push-pull dynamometer, and the top end of each sliding rod passes through the sliding opening and extends to the top of the support plate.

[0008] Preferably, two groups of fixing holes are opened on one side of the support plate, and the support plate is connected to the casing by screws.

[0009] Preferably, a sliding groove is provided on the inner wall of the housing, and two sliders are slidably connected inside the sliding groove, and one end of each slider is connected to the sliding sleeve.

[0010] Preferably, a drive motor is fixedly mounted on the right side of the housing, and an output end of the drive motor is connected to one end of the forward and reverse threaded rod.

[0011] Preferably, a handle is fixedly connected to one side surface of the support plate, and two sets of support legs are fixedly connected to the bottom surface of the housing.

[0012] Preferably, a panel is mounted on the front of the housing by screws, and a control switch is fixedly mounted on the front of the panel.

[0013] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0014] First, by setting two fixing clamps on the casing, the fixing frame is connected to the connecting plate in the casing, and the positive and negative threaded rods are driven by the driving motor to rotate, so that the positive and negative threaded rods act on the two sliding sleeve threads, the spacing between the two fixing clamps can be adjusted, and the magnet is placed between the two fixing clamps. A pressure plate is set inside the fixing clamp, and the rotating wheel drives the screw rod to act on the screw sleeve thread, so that the pressure plate presses and fixes the magnet, thereby ensuring the stability of the magnet during detection.

[0015] Secondly, a push-pull force gauge is set on the top of the casing and an iron plate is set at the bottom of the push-pull force gauge to facilitate the adsorption of the iron plate on the magnet. The push-pull force gauge is driven to rise by the electric push rod on the support plate. The two sliding rods cooperate with the push-pull force gauge to enable the push-pull force gauge to detect the pulling force when the iron plate is separated from the magnet, thereby facilitating the detection of the magnetism of the magnet.
