By setting the sealing box 1, the partition 2, the sealing plate 3, the box cover 5, the positioning box 6, the sliding plate 7, the compression springs 8, the movable plate 9 and the concave pressing plate 10, the electromagnetic permanent magnet chuck body 4 can be pressed and limited, so that the electromagnetic permanent magnet chuck body 4 is closely attached to the sealing plate 3, achieving the sealing of the partition 2. By setting the pressure gauge 11 and the air extraction component 12, the bottom of the inner cavity of the sealing box 1 can be evacuated, so as to achieve the detection of the sealing performance of the electromagnetic permanent magnet chuck body 4. By setting the above structure, the detection bench has the advantage of being convenient to use during use, solving the problem that the original detection bench was not convenient to use during use, thus avoiding affecting the detection results.

[0022] Specifically, the air extraction component 12 includes a vacuum pump 121, the vacuum pump 121 is fixedly connected to the connection part with the sealing box 1 through a support plate, an air extraction pipe 122 is communicated with the right side of the vacuum pump 121, the right side of the air extraction pipe 122 is communicated with the sealing box 1, and an exhaust pipe 123 is communicated with the top of the vacuum pump 121. By setting the vacuum pump 121, the air extraction pipe 122 and the exhaust pipe 123, it is convenient to evacuate the bottom of the inner cavity of the sealing box 1.

[0023] Specifically, a sealing gasket 15 is fixedly connected to the outer surface of the box cover 5, and the outer surface of the sealing gasket 15 is closely attached to the connection part with the sealing box 1. By setting the sealing gasket 15, the connection part between the box cover 5 and the sealing box 1 can be sealed.

[0024] Specifically, rubber pads 16 are fixedly connected to the left and right sides of the bottom of the concave pressing plate 10, and the outer surface of the rubber pads 16 is closely attached to the connection part with the electromagnetic permanent magnet chuck body 4.

By providing the air release valve, it is convenient for the air at the bottom of the inner cavity of the sealing box 1 to enter. By providing the handle, it is convenient to move the box cover 5.

[0028] During use, place the electro-permanent magnetic chuck body 4 on the top of the sealing plate 3. Then, move the handle so that the handle drives the box cover 5 to be placed on the top of the sealing box 1. At the same time, the screw rod 13 passes through the box cover 5 and extends to the top of the box cover 5. Then, sequentially rotate and move the limit nut 14 so that the limit nut 14 threadedly rotates and moves on the outer surface of the screw rod 13 to be closely fitted with the connection of the box cover 5, making the connection between the box cover 5, the sealing gasket 15 and the sealing box 1 closely fitted, thereby sealing the connection between the box cover 5 and the sealing box 1. While the box cover 5 moves downward, the electro-permanent magnetic chuck body 4 presses the concave pressing plate 10 to move, so that the concave pressing plate 10 drives the movable plate 9 to move, and the movable plate 9 drives the sliding plate 7 to slide on the inner surface of the slideway 17 to press the compression spring 8.
