The first embodiment is as follows:
fig. 1 to 4 are schematic structural diagrams illustrating a magnetic force testing apparatus according to a first embodiment of the present invention. In the embodiment, a magnetic testing apparatus is provided, which includes a base plate 10, a first magnet mounting mechanism 20, a second magnet mounting mechanism 30, a push-pull mechanism 40, a detection sensing mechanism 50 and a connecting rod 60, and constitutes a basic structure of the magnetic testing apparatus for accurately testing the interaction magnetic force between two magnets. In assembling and molding the magnetic force testing device, the first magnet mounting means 20 is slidably mounted on the base plate 10, the second magnet mounting means 30 is mounted on the base plate 10, the first magnet mounting means 20 is provided with the first magnet 100, the second magnet mounting means 30 is provided with the second magnet 200 (i.e., of two different magnets to be tested, one of which is mounted on the first magnet mounting means 20 and the other of which is mounted on the second magnet mounting means 30), the second magnet mounting means 30 is disposed opposite to the first magnet mounting means 20, and the second magnet 200 is disposed opposite to the first magnet 100, so that the magnetic force action between the first magnet 100 and the second magnet 200 is realized by moving the first magnet mounting means 20 relative to the second magnet mounting means 30, that is: when the first magnet mounting mechanism 20 moves away from the second magnet mounting mechanism 30, the interaction magnetic force between the first magnet 100 and the second magnet 200 is an attraction force; when the first magnet mounting mechanism 20 moves closer to the second magnet mounting mechanism 30, the mutual magnetic force between the first magnet 100 and the second magnet 200 acts as a repulsive force. The magnetic force testing device is further assembled by mounting the push-pull mechanism 40 on the base plate 10, wherein the push-pull mechanism 40 comprises a push-pull rod 41, the push-pull rod 41 has a push-pull force application end, and the push-pull force application end drives the first magnet mounting mechanism 20 to move relative to the second magnet mounting mechanism 30, thereby realizing the movement of the first magnet mounting mechanism 20 away from or close to the second magnet mounting mechanism 30. And, when mounting the detection sensing mechanism 50, the detection sensing mechanism 50 is located at a side of the second magnet mounting mechanism 30 away from the first magnet mounting mechanism 20, wherein the detection sensing mechanism 50 includes a sensor 51 and a sensor mounting seat 52, wherein the sensor 51 is a sensor capable of testing pressure and testing tension, the sensor mounting seat 52 is fixedly mounted on the base plate 10, and then the sensor 51 is mounted on the sensor mounting seat 52. Then, by connecting the first end of the connecting rod 60 to the second magnet mounting mechanism 30 and locating the second end of the connecting rod 60 on the detecting probe of the sensor 51, when the magnetic force between the first magnet 100 and the second magnet 200 is repulsive force, the second magnet 200 drives the connecting rod 60 to follow up and abut against the detecting probe of the sensor 51, so as to test the pressure, and when the magnetic force between the first magnet 100 and the second magnet 200 is attractive force, the second magnet 200 drives the connecting rod 60 to pull the detecting probe of the sensor 51, so as to test the pulling force. This substantially completes the magnetic force testing device.
When the magnetic force testing device is used for measuring the interaction magnetic force between two magnets, the two magnets need to be fixed on the two magnet mounting mechanisms respectively, that is, the first magnet 100 is fixed on the first magnet mounting mechanism 20, and the second magnet 200 is mounted on the second magnet mounting mechanism 30. Then, the sensor 51 is reset to zero, the first magnet mounting mechanism 20 is moved relative to the second magnet mounting mechanism 30 through operation, so that the magnetic force action between the first magnet 100 and the second magnet 200 is changed, and thus, the change of the magnetic force action between the first magnet 100 and the second magnet 200 and the change of the distance between the first magnet 100 and the second magnet 200 have a functional relationship, so that the obtained functional relationship is used for calculating and representing the magnetic force action relationship between the first magnet 100 and the second magnet 200, the measurement accuracy is greatly improved, and the sensor 51 is used for directly measuring and representing the magnetic force action between the first magnet 100 and the second magnet 200, the accuracy of 0.1N can be achieved, and the measurement accuracy is greatly improved compared with the measurement accuracy of a hanging weight in the prior art. In addition, in the magnetic force testing apparatus, the second magnet mounting mechanism 30 and the sensor 51 are connected by the connecting rod 60, so that the sensor 51 and two magnets to be measured keep a considerable distance, thereby reducing the magnetic field interference of the magnet on the sensor 51 and ensuring the measurement accuracy of the sensor 51. Moreover, the magnetic force testing device is simple in design structure and low in manufacturing cost, so that the cost of measuring the magnetic force action between the two magnets is reduced.
In the first embodiment, the magnetic force testing apparatus further includes a shielding case 70 capable of shielding the magnetic field. The shield cover 70 is covered on the bottom plate 10 to form a shield space, the detection sensing mechanism 50 is entirely located in the shield space, and the second end of the connecting rod 60 passes through the shield cover 70 and then is arranged on the detection probe of the sensor 51. In this way, the magnetic fields generated by the two magnets with test are shielded by the shielding case 70, so that the influence of the magnetic field on the magnetic field interference of the sensor 51 is weakened, and the second magnet mounting mechanism 30 and the sensor 51 are connected by the transfer of the connecting rod 60, so that the magnetic field interference of the magnetic field on the sensor 51 is weakened to the minimum degree, and the accuracy of the sensor 51 in testing the magnetic force action between the first magnet 100 and the second magnet 200 is ensured.
In order to further reduce the interference effect of the magnetic fields generated by the first and second magnets 100 and 200 on the sensor 51, all the components of the magnetic force testing apparatus are made of non-magnetic materials.
Specifically, the first magnet mounting mechanism 20 includes a magnet mounting base 21 and a clamping jaw (not shown), the magnet mounting base 21 is slidably mounted on the base plate 10, the clamping jaw is mounted on the magnet mounting base 21, the first magnet 100 is clamped and fixed by the clamping jaw, and the push-pull force application end of the push-pull rod 41 drives the magnet mounting base 21 to move relative to the second magnet mounting mechanism 30. Correspondingly, the magnetic force testing device further comprises a guide straight rail 80, the guide straight rail 80 is fixedly installed on the base plate 10, and the magnet installation seat 21 is connected to the guide straight rail 80 in a sliding manner. Further, the first magnet mounting mechanism 20 further comprises a mounting base 22 and a sliding block 23, the magnet mounting base 21 is fixedly mounted on one side mounting surface of the mounting base 22, and the sliding block 23 is connected on the other side mounting surface of the mounting base 22, which is far away from the magnet mounting base 21, that is, the sliding block 23 moves along the guide straight rail 80 to realize the relative movement between the first magnet mounting mechanism 20 and the second magnet mounting mechanism 30. Moreover, two guide straight rails 80 are arranged, so that in the relative movement process between the first magnet installation mechanism 20 and the second magnet installation mechanism 30, the two guide straight rails 80 and the sliding block 23 can interact with each other to ensure that the first magnet installation mechanism 20 does not turn on one side, and the fixed and accurate position of the first magnet installation mechanism 20 is ensured.
In the first embodiment, it is preferable that the second magnet mounting mechanism 30 has the same structure as the first magnet mounting mechanism 20, and the specific assembly process of the second magnet mounting mechanism 30 refers to the first magnet mounting mechanism 20, and thus, the detailed description thereof is omitted. When the second magnet mounting mechanism 30 is assembled and tested, generally, the position on the guide straight rail 80 where the second magnet mounting mechanism 30 moves is related to the length of the selected connecting rod 60, and when the length of the selected connecting rod 60 is determined, the second magnet mounting mechanism 30 correspondingly moves to the determined position on the guide straight rail 80, and then the mounting base 22 of the second magnet mounting mechanism 30 is fixed with the base plate 10.
As shown in fig. 1 to 4, the push-pull rod 41 of the first embodiment is a lead screw, so the push-pull mechanism 40 further includes a lead screw nut bracket 42, the lead screw nut bracket 42 is fixedly mounted on the base plate 10, and the lead screw is connected to the lead screw nut bracket 42 in a fitting manner, so that when the lead screw rotates relative to the lead screw nut bracket 42, the push-pull force application end of the lead screw linearly moves relative to the lead screw nut bracket 42 along the axis of the lead screw (the push-pull force application end is close to or far from the lead screw nut bracket 42). And, the other end of the screw rod opposite to the push-pull force application end is a connection end, and the connection end is equipped with a hand wheel 43. In the process of testing, after the first magnet 100 and the second magnet 200 are mounted, the hand wheel 43 is manually rotated to drive the lead screw to rotate, and the lead screw moves linearly relative to the lead screw nut bracket 42, so as to drive the first magnet mounting mechanism 20 to move away from or close to the second magnet mounting mechanism 30.
In the testing process, the distance between the first magnet 100 and the second magnet 200 needs to be changed for multiple times to perform testing, so that multiple groups of data are obtained, and then a magnetic interaction curve graph of the two magnets is drawn, and a function equation is obtained. In order to prevent the first magnet mounting mechanism 20 from suddenly changing the relative distance with respect to the second magnet mounting mechanism 30 to affect the test after each change of the relative distance between the first magnet 100 and the second magnet 200, the magnetic testing apparatus further comprises an axial positioning clamp 90, the axial positioning clamp 90 is fixedly connected to the side of the first magnet mounting mechanism 20 away from the second magnet mounting mechanism 30, and after each change of the relative distance between the first magnet 100 and the second magnet 200, the axial positioning clamp 90 is used to clamp and position the push-pull rod (i.e., clamp and position the lead screw) to prevent the lead screw from suddenly acting on external force to drive the first magnet mounting mechanism 20 to change the mutual distance with respect to the second magnet mounting mechanism 30.
