[0002] The components of magnets are iron, cobalt, nickel and other atoms. The internal structure of the atoms is quite special and they have magnetic moments. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals.

[0003] For example, a ring magnet detection tool with publication number CN213532344U has the following problems: 1. In order to prevent the detection table from tipping over during operation, it is necessary to use a metal detection table to increase its weight to prevent it from tipping over. However, when the magnet is placed in the fixed groove during operation, the magnet is easy to contact with the side wall and bottom wall of the fixed groove over a large area and be magnetically fixed. At the same time, the distance between the outer wall of the magnet and the inner wall of the fixed groove is limited, which makes it difficult for people to take the magnet out of the fixed groove; 2. The arc-shaped clamping plate is pushed only by the expansion force of the spring, which makes the arc-shaped clamping plate unstable and easy to shake under external influences, making it difficult for the two sets of arc-shaped clamping plates to lock the magnet in the fixed groove, thereby affecting the processing effect of the magnet. Summary of the invention

[0004] The purpose of the present invention is to provide a magnet detection tool.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A magnet detection tool comprises a detection table, wherein a circular fixing groove for accommodating a magnet is provided on the top of the detection table:

[0007] An operating cavity is provided in the detection table below the fixed groove, wherein a circular hole communicating with the operating cavity is provided in the middle of the bottom of the fixed groove, and sliding openings communicating with the operating cavity are provided at the bottom of the fixed groove on both sides of the circular hole, and a circular seat is provided at the bottom of the fixed groove, wherein an electric push rod passing through the circular hole and connected to the circular seat is provided in the operating cavity, and four groups of fan-shaped notches are radially provided on the outer side wall of the circular seat, and an arc-shaped plate with a top passing through the corresponding fan-shaped notches is provided in the sliding opening, wherein positive and negative screw rods passing through the bottom ends of the two groups of arc-shaped plates are provided in the operating cavity, and the positive and negative screw rods are driven by motor I;

[0008] A circle of suction channels is arranged around the side wall of the circular seat and located between the four groups of fan-shaped notches, wherein suction holes connected to the suction channels are evenly arranged on the top surface of the circular seat, and the suction channels are connected to the vacuum pump through a pipeline, and a strip groove is also arranged on the top surface of the circular seat and located between the multiple groups of suction holes, wherein a rotating shaft driven by motor II is arranged in the strip groove, and multiple groups of push rods are arranged on the rotating shaft.

[0009] Preferably, a rubber cushion layer is provided on the top surface of the circular seat.

[0010] Preferably, the top end of the arc-shaped plate is lower than the horizontal plane of the top end of the fixing groove, wherein a groove for accommodating the pressure sensor is provided on one end surface of the arc-shaped plate.

[0011] Preferably, the bottom end of the pipe passes downward through a circular hole opening.

[0012] Preferably, a screw tube threadedly connected to the forward and reverse screw rods is provided on the arc plate, wherein bearings for fixing the ends of the forward and reverse screw rods are provided on the side walls of the operating chamber, and the motor I is arranged in the operating chamber, wherein a gear is provided on the output shaft of the motor I, and a gear ring meshing with the gear is provided on the forward and reverse screw rods.

[0014] Preferably, the length of the push rod is greater than the distance between the rotating shaft and the top end of the circular seat.

[0015] The beneficial effect of the present invention is that the present invention achieves the purpose of clamping and fixing the magnet by mechanically driving the arc plate to move so as to facilitate its subsequent processing, so as to make the magnet not easy to move so as to improve its processing efficiency and effect, wherein the contact area between the magnet and the circular seat is reduced by the fan-shaped notch, and the arc-shaped plate is used to clamp and fix the magnet to prevent it from contacting the inner wall of the fixed groove, thereby preventing the magnet from contacting the above-mentioned components over a large area and magnetically fixing it, which makes it difficult for people to remove the magnet from the fixed groove. When the magnet needs to be removed, the arc-shaped plate moves outward to release the magnet, and the electric push rod drives the circular seat to move upward. Then, when the circular seat slides out of the fixed groove, the air intake channel is deflated at this time, and people can grab the bottom edge of the magnet through the fan-shaped notch and then remove it from the circular seat. Of course, the motor II can also drive the rotating shaft to drive the push rod to slide out of the strip groove, thereby lifting the magnet up or tilting it, reducing the contact area between it and the end face of the circular seat, so that people can remove the magnet easily.

DETAILED DESCRIPTION

[0019] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0020] A magnet detection tool comprises a detection platform 1, wherein a circular fixing groove 2 for accommodating a magnet is provided on the top of the detection platform 1:

[0021] An operating cavity 3 is provided in the detection table 1 below the fixing groove 2, wherein a circular hole 4 communicating with the operating cavity 3 is provided in the middle of the bottom of the fixing groove 2, and sliding openings 5 ​​communicating with the operating cavity 3 are provided at the bottom of the fixing groove 2 on both sides of the circular hole 4, a circular seat 6 is provided at the bottom of the fixing groove 2, and a rubber cushion layer is provided on the top surface of the circular seat 6, wherein an electric push rod 7 passing through the circular hole 4 and connected to the circular seat 6 is provided in the operating cavity 3, and four groups of fan-shaped notches 8 are radially provided on the outer side wall of the circular seat 6;

[0022] The sliding opening 5 is provided with an arc plate 9 whose top passes through the corresponding fan-shaped notch 8, wherein the operating chamber 3 is provided with a forward and reverse screw rod 10 passing through the bottom ends of the two groups of arc plates 9, and the forward and reverse screw rod 10 is driven by a motor I11;

[0023] A circle of suction channels 12 is arranged around the side wall of the circular seat 6 and is located between the four groups of fan-shaped notches 8, wherein suction holes 13 connected to the suction channels 12 are evenly arranged on the top surface of the circular seat 6, and the suction channels 12 are connected to the vacuum pump through a pipe 14, and the bottom end of the pipe 14 passes downward through the circular hole 4 opening, and a strip groove 15 is also arranged on the top surface of the circular seat 6 and is located between the multiple groups of suction holes 13, wherein a rotating shaft 16 driven by a motor II17 is arranged in the strip groove 15, and multiple groups of push rods 18 are arranged on the rotating shaft 16, and the length of the push rods 18 is greater than the distance between the rotating shaft 16 and the top of the circular seat 6.

[0024] In this embodiment, the top of the arc plate 9 is lower than the horizontal plane of the top of the fixing groove 2 , wherein a groove for accommodating the pressure sensor 19 is provided on one end surface of the arc plate 9 .

[0025] In this embodiment, a screw tube threadedly connected to the forward and reverse screw rods 10 is arranged on the arc plate 9, wherein bearings for fixing the ends of the forward and reverse screw rods 10 are arranged on the side walls of the operating chamber 3, and the motor I11 is arranged in the operating chamber 3, wherein a gear is arranged on the output shaft of the motor I11, and a gear ring meshing with the gear is arranged on the forward and reverse screw rods 10.

[0026] like Figure 2 As shown, the motor II17 is arranged in one group of the fan-shaped notches 8, wherein the motor II17 is located in the fan-shaped notch 8 between the upper and lower ends of the circular seat 6. The motor II17 does not extend to the outer sides of the upper and lower ends of the circular seat 6.

[0027] Then, when in use, the electric push rod drives the circular seat to move upward in the fixed groove to move to the outer side of the top, so that it is convenient for people to place the magnet in the middle area of ​​the top of the circular seat, and then the electric push rod drives the circular seat to reset downward to drive the magnet to slide into the fixed groove. At this time, the magnet on the circular seat is located between the multiple groups of arc plates, and then the motor I drives the positive and negative screw rods to rotate in the screw tubes on the corresponding arc plates to drive the arc plates to slide in the sliding opening and the fan-shaped notch, and then clamp the magnet on the circular seat, so as to achieve the purpose of clamping and fixing the magnet by mechanically driving the arc plate to move so as to facilitate its subsequent processing, so as to make the magnet not easy to move to improve its processing efficiency and effect;

[0028] At the same time, the vacuum pump draws vacuum through the pipe 14, the air suction channel 12 and the air suction hole 13, thereby adsorbing and fixing the magnet on the circular seat 6. It should be noted that at this time, the air suction hole 13 is blocked and covered by the bottom end surface of the magnet. Since the magnet is adsorbed and fixed on the circular seat 6 by vacuuming at this time, the probability of the magnet sliding off the circular seat 6 is reduced;

[0029] In the above process, the contact area between the magnet and the circular seat 6 is reduced by the fan-shaped notch 8, and the arc-shaped plate 9 is used to clamp the fixed magnet to prevent it from contacting the inner wall of the fixed groove 2, thereby preventing the magnet from contacting the above components over a large area and being magnetically fixed, which makes it difficult for people to remove the magnet from the fixed groove 2;

[0030] When the magnet needs to be taken out, the arc plate 9 moves outward to release the magnet, and the electric push rod 7 drives the circular seat 6 to move upward. Since the magnet is adsorbed on the circular seat 6 by vacuuming, the circular seat 6 will not slip when the magnet moves upward. Then, when the circular seat 6 slides out of the fixed groove 2, the air suction channel 12 is deflated at this time, and people can grab the bottom edge of the magnet through the fan-shaped notch 8 and then remove it from the circular seat 6. Of course, the motor II17 can also drive the rotating shaft 16 to drive the push rod 18 to slide out of the strip groove 15, and then lift the magnet up and suspend it in the air or tilt it up, reducing the contact area between it and the end face of the circular seat 6, so that people can remove the magnet and prevent people from not being able to grab the magnet well from the fan-shaped notch 8. When the magnet is tilted, the above problem is just solved, making it easy for people to grab the edge of the magnet while reducing the magnetic contact area between it and the circular seat 6.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
