Description

Technical Field

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

[0002] The components of a magnet are atoms such as iron, cobalt, nickel, etc. The internal structure of its atoms is relatively special and it has a magnetic moment itself. A magnet can generate a magnetic field, has the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals, and has the property that like magnetic poles repel each other and unlike magnetic poles attract each other. When producing a magnet, a magnetization step will be carried out, and most factories are completed by manual operation. During the magnetization process, there are phenomena of missed magnetization or insufficient magnetization amount. After the magnet is magnetized, the magnet combination is inside the product. Before the product leaves the factory, magnetic detection needs to be carried out to ensure the quality of the product.

[0003] In the existing detection equipment, a magnetic detection machine needs to be used to detect the magnetism of the magnet. After the detection, data analysis and transmission are also required. The detection takes a long time. For the already produced magnetic products, most only need to detect the magnetic strength. If it cannot be carried out quickly, the production efficiency of the product will be delayed. And for some employees with insufficient professional level, there are also problems of operation errors when using the detection machine, which affects the detection quality.

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

[0005] In order to overcome the above-mentioned disadvantages, the utility model provides a magnet magnetic detection device.

[0006] A magnet magnetic detection device includes a connecting cylinder, a fixed sleeve, a second magnet, a connecting block, a sliding rod, a compression spring and a prompting component. The bottom of the connecting cylinder is connected with the fixed sleeve. The sliding rods are symmetrically connected inside the connecting cylinder. The lower sides of the sliding rods are all slidably connected with the connecting blocks. A second magnet is connected between the two connecting blocks. Compression springs are connected between the two connecting blocks and the inner top of the connecting cylinder. The compression springs are sleeved on the sliding rods. A prompting component is arranged on the connecting cylinder.

[0007] Further explanation, the prompting component includes a first prompting block, a second prompting block, a reset spring, an inclined block and a top block. A display groove is opened in the middle of the top of the connecting cylinder. The first prompting block is slidably connected at a position close to the display groove inside the top of the connecting cylinder. The second prompting block is connected to the rear side of the first prompting block. The second prompting block is slidably connected to the inside of the connecting cylinder, and initially the second prompting block is aligned with the display groove. A reset spring is connected between the first prompting block and the inside of the connecting cylinder. The top block is connected to the top of the second magnet. The inclined block is connected to the bottom of the first prompting block. The top block can contact the inclined block when moving upward.

[0008] Further explanation: The first prompt block and the second prompt block have different colors. The color of the second prompt block is red, and the color of the first prompt block is green. When aligned with the display slot, the movement state of the second magnet can be known by checking the color displayed on the display slot.

[0009] Further explanation: The detection device further includes a first magnet. The first magnet is connected inside the fixed sleeve. The fixed sleeve isolates the first magnet from the second magnet, and there is no magnetic relationship between the first magnet and the second magnet.

[0010] Further explanation: The detection device further includes a grip. The grip is connected to the rear side of the connecting cylinder.

[0011] Further explanation: The detection device further includes a transparent block.

[0012] The beneficial effects of the present utility model are as follows: 1. Hold the device against the measured part. When the magnetism of the measured part is qualified, due to the repulsive force between the measured part and the second magnet, the second magnet can drive the top block to move upward and push the inclined block, so that the first prompt block is displayed on the display slot, and it can be directly known whether the magnetism of the measured part is qualified. The operation is simple and fast.

[0013] 2. The first prompt block and the second prompt block have different colors. When the magnetism of the measured part is insufficient, the second prompt block remains in the state displayed on the display slot. By checking the transparent block, the movement of the second magnet can also be understood, and then the magnetism strength of the measured part can be known. Description of the Drawings

Detailed Embodiment

[0018] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but not to limit the present utility model.

[0019] Embodiment: A magnet magnetic detection device, as Figures 1-3 shown, includes a connecting cylinder 1, a fixing sleeve 2, a second magnet 4, a connecting block 5, a sliding rod 6, a compression spring 7 and a prompting component. The bottom of the connecting cylinder 1 is connected to the fixing sleeve 2. The sliding rods 6 are symmetrically welded to the left and right inside the connecting cylinder 1. The lower sides of the sliding rods 6 are all connected to the connecting block 5 in a sliding manner. A second magnet 4 is connected between the two connecting blocks 5. Compression springs 7 are connected between the two connecting blocks 5 and the inner top of the connecting cylinder 1. The compression springs 7 are sleeved on the sliding rods 6. A prompting component is provided on the connecting cylinder 1.

[0020] As Figures 1-3 shown, the prompting component includes a first prompting block 9, a second prompting block 10, a reset spring 11, an inclined block 12 and a top block 13. A display groove 91 is opened in the middle of the top of the connecting cylinder 1. The first prompting block 9 is connected to the inner top of the connecting cylinder 1 near the display groove 91 in a sliding manner. The second prompting block 10 is connected to the rear side of the first prompting block 9. The second prompting block 10 is slidably connected to the inside of the connecting cylinder 1. The first prompting block 9 and the second prompting block 10 have different colors. The color of the second prompting block 10 is red, and the color of the first prompting block 9 is green. When aligned with the display groove 91, the moving state of the second magnet 4 can be known by checking the color displayed on the display groove 91. A reset spring 11 is connected between the first prompting block 9 and the inside of the connecting cylinder 1. The top block 13 is connected to the top of the second magnet 4. The inclined block 12 is connected to the bottom of the first prompting block 9. The upward movement of the top block 13 can contact the inclined block 12, thereby pushing the inclined block 12 to move backward.

[0021] As Figures 1-3 shown, the detection device further includes a first magnet 3, a grip 8 and a transparent block 14. The first magnet 3 is connected inside the fixing sleeve 2. The fixing sleeve 2 isolates the first magnet 3 from the second magnet 4. There is no magnetic relationship between the first magnet 3 and the second magnet 4. The grip 8 is connected to the rear side of the connecting cylinder 1. The transparent block 14 is connected to the middle of the front side of the connecting cylinder 1, and the movement of the second magnet 4 can be viewed.

[0022] When using this device to magnetically detect magnetic parts or products, hold the grip 8 with your hand and place the connecting cylinder 1 on the object to be measured. Since the contact magnetic poles of the first magnet 3 and the object to be measured are different, the first magnet 3 will magnetically adsorb to the object to be measured, thereby stabilizing the connecting cylinder 1. When the connecting cylinder 1 is attached to the object to be measured, the second magnet 4 approaches the object to be measured. The magnetic pole of the second magnet 4 is the same as that of the object to be measured, and a mutual repulsion effect will occur. The mutual repulsion force will cause the second magnet 4 and the connecting block 5 to move upward, thereby driving the top block 13 to move upward and compressing the compression spring 7. The magnitude of the mutual repulsion force is related to the magnetism of the object to be measured. The stronger the magnetism, the greater the mutual repulsion force. If the magnetism of the object to be measured is qualified, the upward movement of the top block 13 will contact the inclined block 12, thereby pushing the inclined block 12 to move backward, driving the first prompt block 9 and the second prompt block 10 to move backward. The second prompt block 10 is not aligned with the display slot 91, while the first prompt block 9 is aligned with the display slot 91. At this time, the green first prompt block 9 can be seen from the display slot 91, indicating that the magnetism of the object to be measured is qualified. When the magnetism is weak or there is no magnetism, no magnetic field will be generated, and there will be no repulsion between the object to be measured and the second magnet 4. The inclined block 12 will not be pushed, and the state shown by the red second prompt block 10 will be maintained on the display slot 91, indicating that the magnetism of the object to be measured is unqualified. The movement of the second magnet 4 can also be known by checking the transparent block 14. After the test is completed, remove the connecting cylinder 1 from the object to be measured. The first magnet 3 no longer adsorbs the object to be measured, and the magnetic field of the second magnet 4 also disappears. The connecting block 5 will drive the second magnet 4 and the top block 13 to move downward and reset under the reset action of the compression spring 7. The magnetic detection work can be completed according to the above operations, and the operation is simple and easy to understand.

[0023] It should be understood that the above description is only for illustrative purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
