Description

Technical Field

[0001] The utility model relates to the technical field of magnet pole detection, in particular to a magnet pole detection tooling. Background Art

[0002] Magnets are one of the basic components commonly used in various mechanical equipment. In the production and manufacturing process of magnets, a magnetic conductor needs to be processed first, and then the magnetic conductor is magnetized by a magnetizer to make it a magnet. After the magnet is produced, in order to facilitate users to distinguish the two poles of the magnet, some manufacturers will design a mark on one or both poles of the magnet for distinction. At the same time, it is necessary to detect the magnetic force of the magnet before leaving the factory to exclude some magnets with incomplete magnetization. This requires the use of detection tooling.

[0003] In the existing technology, the detection tooling generally manually approaches the magnet part to be detected to the magnet block, and judges whether the magnetic pole direction of the magnet is correct based on the principle of "like poles repel, opposite poles attract". This method is more troublesome to operate and not intuitive enough. Moreover, when judging the magnetic force, it depends on the feeling to judge, there is a certain error, and it is difficult to distinguish the magnetic force of the magnet.

[0004] Based on this, in order to solve the above-mentioned technical defects, a magnet pole detection tooling is proposed. Content of the Utility Model

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a magnet pole detection tooling.

[0006] The technical solution is as follows: A magnet pole detection tooling includes a frame body, a partition board, a threaded rod, a guide rod, a first spring, a magnet block, a pointer, a measuring scale and a prompting component. There are two frame bodies in total, and the two frame bodies are symmetrically distributed and adhered to each other. Partition boards are connected to the sides of the two frame bodies close to each other. A guide rod is connected to the rear side of the right frame body, and the left frame body is slidably connected to the guide rod. A threaded rod is threadedly connected between the rear sides of the right frame body and the left frame body. By rotating the threaded rod, the distance between the two frame bodies can be adjusted. Magnet blocks are slidably connected inside both frame bodies, and first springs are connected between the magnet blocks and the inside of the frame bodies on the same side. Pointers are connected to the tops of the two magnet blocks, and measuring scales are connected to the rear sides of the tops of the two frame bodies. A prompting component is arranged on the frame body.

[0007] Optionally, the magnet part to be detected can be placed between the two partition boards.

[0008] Optionally, the front sides of the two partition boards are in an eight-shaped state.

[0009] Optionally, the magnetic poles are marked on the top surfaces of the two magnet blocks, and the N-pole surfaces of the two magnet blocks are in positions close to each other, while the S-pole surfaces are in positions far from each other.

[0010] Optionally, the prompting component includes fixing blocks, switches, indicator lights, a controller, and auxiliary components. Fixing blocks are connected to the tops of the partition plates. Switches are slidably connected inside the fixing blocks. Indicator lights are connected to the front sides of the frames. The controller is installed on the front side of the right frame. The indicator lights and the switches are electrically connected to the controller. An auxiliary component is provided on the magnet block.

[0011] Optionally, the auxiliary component includes a second spring and a top block. Top blocks are connected to the tops of the magnet blocks. Second springs are connected between the switches and the interiors of the fixing blocks on the same side. The top blocks are in contact and cooperation with the switches on the same side.

[0012] The beneficial effects of the present utility model are as follows: 1. By placing the magnet piece between the two partition plates, according to the principle of like poles attracting and unlike poles repelling of the magnet piece, the magnet blocks on the side of unlike poles repelling will move outward to detect the N pole surface and S pole surface of the magnet piece, and the operation is simple and fast.

[0013] 2.

Detailed Embodiment

[0019] The following is only the preferred embodiment of the present utility model, and it does not limit the protection scope of the present utility model accordingly.

[0020] Embodiment: A magnet pole detection tooling, as Figures 1-4As shown in the figure, it includes a housing 1, a partition 101, a threaded rod 2, a guide rod 3, a first spring 4, a magnet block 5, a pointer 6, a measuring scale 7 and a prompting component. There are two housings 1 in total. The two housings 1 are symmetrically distributed and in contact with each other. On one side of the two housings 1 close to each other, there is a partition 101 for placing magnet parts. The front sides of the two partitions 101 are in a shape of an inverted V, which is conducive to placing the magnet part to be measured. A guide rod 3 is welded to the rear side of the right housing 1, and the left housing 1 is slidably connected to the guide rod 3. A threaded rod 2 is threadedly connected between the rear sides of the right housing 1 and the left housing 1. By rotating the threaded rod 2, the distance between the two housings 1 can be adjusted. Inside the two housings 1, there is a magnet block 5 slidably connected. Between the magnet block 5 and the inside of the housing 1 on the same side, there is a first spring 4 connected. On the top surfaces of the two magnet blocks 5, the magnetic poles are marked, and the N-pole surfaces of the two magnet blocks 5 are in a position close to each other, while the S-pole surfaces are in a position away from each other. On the top of the two magnet blocks 5, there is a pointer 6 connected. On the rear sides of the tops of the two housings 1, there is a measuring scale 7 connected. The pointer 6 points to the scale on the measuring scale 7. On the housing 1, there is a prompting component for prompting the detection result.

[0021] As Figure 1 and Figure 4 shown in the figure, the prompting component includes a fixed block 8, a switch 9, an indicator light 12, a controller 21, a second spring 10 and a top block 11. Fixed blocks 8 are welded to the tops of the partitions 101. Inside the fixed blocks 8, there is a switch 9 slidably connected. On the front sides of the housings 1, there is an indicator light 12 connected by bolts. On the front side of the right housing 1, there is a controller 21 installed by bolts. The indicator light 12 and the switch 9 are both electrically connected to the controller 21. There is an auxiliary component on the magnet block 5. On the top of the magnet block 5, there is a top block 11 welded. Between the switch 9 and the inside of the fixed block 8 on the same side, there is a second spring 10 connected. The top blocks 11 are in contact and cooperation with the switches 9 on the same side.

[0022] When detecting the magnetic poles of a magnet component, place the magnet component between the two partition plates 101. The magnet blocks 5 are close to the two magnet blocks 5. According to the principle that like poles of magnets repel each other and opposite poles attract each other, when the magnet component is placed between the two partition plates 101, the S pole and N pole of the magnet block 5 are respectively close to the N poles of the two magnet blocks 5. When the N pole of the magnet component is close to the N pole of one of the magnet blocks 5, due to the mutual repulsion of the magnetic fields, the magnet block 5 and the magnet component will push each other away, showing the characteristic of like poles repelling each other. When the S pole of the magnet component is close to the N pole of one of the magnet blocks 5, due to the opposite directions of the magnetic fields, they will attract each other, showing the characteristic of opposite poles attracting each other. The magnet block 5 close to the N pole of the magnet component will be pushed to move outward, compressing the first spring 4. The magnet block 5 drives the top block 11 to move outward. Initially, the second spring 10 is in a compressed state. When the top block 11 moves outward and no longer presses the switch 9, the switch 9 will move outward due to the reset of the second spring 10, and the controller 21 will control the indicator light 12 on the corresponding side to light up. At this time, it can be known which side of the magnet component is the N pole and which side is the S pole. The indicator light 12 can play an indicating role. When the magnet block 5 moves outward, it will also drive the pointer 6 to move outward. The pointer 6 will point to the scale on the measuring ruler 7, and the mutual repulsion force between the magnet component and the magnet block 5 can be known. The stronger the magnetism of the magnet component, the greater the mutual repulsion force. And the closer the distance between the magnet component and the magnet block 5, the greater the mutual repulsion force will also be. Thus, the magnetic force of the magnet component can be known, which is beneficial for detection. After the detection is completed, mark the magnet component. After the magnet component is taken out and away from the two magnet blocks 5, the mutually repelling magnet blocks 5 will move inward and reset under the reset of the first spring 4, and then drive the top block 11 to move and reset. The top block 11 will press the switch 9, compressing the second spring 10. The controller 21 will then control the indicator light 12 to turn off. The reset of the magnet block 5 also drives the pointer 6 to move and reset. When using this device, the distance between the two partition plates 101 can be adjusted by adjusting the distance between the two frames 1. Press the right frame 1 and rotate the threaded rod 2, then the left frame 1 can be driven to move outward, and the distance between the two frames 1 can be increased to facilitate placing magnet components of different sizes in the gap between the partition plates 101, increasing the flexibility of use. Reverse the threaded rod 2, then the left frame 1 can be made to move inward, shortening the distance between the two frames 1.

[0023] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
