Description

Technical Field

[0001] The utility model relates to the technical field of magnet testing, in particular to a magnet suction force testing device. Background Technique

[0002] Magnets with specific strengths are required in devices such as speakers, sensors, and magnetic separators. To evaluate whether a magnet is suitable for specific industrial applications, such as magnetic fixtures and magnetic filters, a magnet suction force testing device is needed to perform the suction force test of the magnet, so as to ensure its magnetic performance and effectiveness in actual applications.

[0003] The prior art has the following deficiencies: In the prior art, the application number is 201420289420.1, which proposes a magnet suction force testing device for testing the magnet suction force of a product. The magnet suction force testing device includes: a base; a back plate vertically established on the base; a test base and a fixing plate arranged on the test base. The test base is arranged on the upper plane of the base, and the fixing plate is arranged on the test base for placing the product to be tested; a tensiometer, which is arranged on the back plate in parallel and can slide up and down through a lead screw; a suction force test seat and a suction force test iron sheet arranged on the suction force test seat. The suction force test seat is connected to the lower end of the tensiometer; a test control system is arranged in the base, and the test control system is connected to the lead screw and the tensiometer for controlling the action of the lead screw and reading the test results of the tensiometer. The utility model has the advantages of high test efficiency, good test effect, and effective reduction of labor costs.

[0004] When the above device is used, a test base and a fixing plate are used to place the magnet to be tested. The magnet to be tested is only fixed by the fixing plate, and the specific fixing structure is not clear, which cannot ensure the stability of the magnet with a large suction force itself during the test. At the same time, since the contact area between the magnet to be tested and the output end structure of the tensiometer during the test will affect the specific test value, the suction force on different surfaces of the magnet to be tested is different. If it is necessary to test the suction force on different surfaces of the magnet to be tested, it is inconvenient to perform multi-directional tests. Content of the Utility Model

[0027] Specifically, through the support rods 2, the stability of the top plate 3 can be supported.

[0028] In this embodiment, the bracket 6 is fixedly installed on the top of the top plate 3 and corresponds to the installation opening 4. There are two groups of cylinders 7 fixedly installed on the top of the bracket 6;

[0029] Specifically, through the bracket 6, the installation of the cylinder 7 can be facilitated.

[0030] In this embodiment, the connecting piece 5 is sleeved and fixedly installed on the top of the tensiometer 8. The adsorption plate 9 is fixedly installed at the output end of the tensiometer 8. Four groups of connecting rods 10 are obliquely connected to the upper surface of the adsorption plate 9.

[0031] Specifically, through the tensiometer 8, the magnet suction force can be displayed in the form of tension. Through the adsorption plate 9, it is convenient to contact and adsorb the magnet to be tested.

[0032] In this embodiment, the connecting piece 5 is adapted to the installation opening 4. The connecting piece 5 is located in the installation opening 4. The output end of the cylinder 7 passes through the bracket 6 and is fixedly connected to the top of the connecting piece 5;

[0038] The working principle and usage process of the present utility model: During actual use, the overall device is placed in a suitable position through the bottom plate 1. The magnet to be tested is placed between the two threaded rods 13. By turning the threaded rod 13, the threaded rod 13 is pushed inwards until the tightening member 1302 abuts against both sides of the magnet to be tested, thereby stably clamping the magnet to be tested. The anti-slip pad 1303 can increase the friction between the magnet to be tested and the tightening member 1302, and ensure the stability of the magnet clamping. Then, control the output end of the air cylinder 7 to descend, driving the tensiometer 8 to descend until the adsorption plate 9 contacts the upward surface of the magnet to be tested clamped between the two threaded rods 13 and generates magnetic adsorption. Adjust the tensiometer 8 to the peak hold mode and zero the value. Continuously lift the tensiometer 8 through the air cylinder 7 until the adsorption plate 9 disengages from the magnet to be tested between the two threaded rods 13. At this time, the peak value of the tensile force recorded on the tensiometer 8 is the highest tensile force generated before the adsorption plate 9 disengages from the magnet to be tested, thereby obtaining the highest suction force on one side of the magnet to be tested. If it is necessary to test the suction force on different surfaces of the magnet, the magnet to be tested can be directly rotated when the tensiometer 8 is lifted. The bearings 1301 at the ends of the two threaded rods 13 can ensure flexible rotation. Just place the side of the magnet to be tested facing upwards corresponding to the adsorption plate 9, or it can also be rotated through the bearing 1301 after changing the orientation of the magnet to be tested in the same way as above, and multi-directional testing of the magnet can be carried out.
