[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figures 1-3, A magnetic press-fitting positioning tooling, including a conveyor 1 and a U-shaped plate 2. The U-shaped plate 2 is installed on the outer wall of the conveyor 1, and a positioning structure 3 is arranged on the inner wall of the U-shaped plate 2. By placing the workpiece on the roller shaft of the conveyor 1 and starting the conveyor 1 to transport the workpiece to the U-shaped plate 2, the positioning structure 3 includes a base 301 installed on the inner wall of the U-shaped plate 2. A first electromagnetic rod 302 is rotatably connected to the inner wall of the base 301. The roller shaft of the conveyor 1 and the first electromagnetic rod 302 are on the same horizontal plane. Both ends of the second electromagnetic rod 303 are rotatably connected to the inner wall of the base 301, and the four first electromagnetic rods 302 are evenly distributed around the base 301. When the workpiece contacts the first electromagnetic rod 302, the conveyor 1 drives the workpiece to continue moving under force.

[0029] A first rotating rod 304 is movably connected to the inner wall of the base 301. One end of the first rotating rod 304 away from the base 301 is rotatably connected to the second electromagnetic rod 303. The first electromagnetic rod 302 and the second electromagnetic rod 303 are on the same horizontal plane. The conveyor 1 and the first electromagnetic rod 302 cooperate to continue driving the workpiece to move onto the second electromagnetic rod 303. A first connecting block 305 is attached to the bottom of the first rotating rod 304. A first spring 306 is installed on the bottom wall of the first connecting block 305. One end of the first spring 306 away from the first connecting block 305 is installed with a switch 308. The top wall of the first connecting block 305 is arc-shaped, which is convenient for fitting with the first rotating rod 304. The first connecting block 305 and the first rotating rod 304 are fitted together by the elastic force of the first spring 306.

[0030] A first abutting column 307 is installed on the bottom wall of the first connecting block 305. The bottom wall of the first abutting column 307 is not in contact with the top wall of the switch 308. There is a certain distance between the bottom wall of the first abutting column 307 and the switch 308. The first abutting column 307 is located inside the first spring 306. When the workpiece moves onto the second electromagnetic rod 303, the second electromagnetic rod 303 drives the first rotating rod 304 and the first connecting block 305 to move downward under force. At this time, the first connecting block 305 drives the first spring 306 to contract, and the first abutting column 307 moves towards the switch 308 along with the first connecting block 305. After the first abutting column 307 contacts the switch 308, the second electromagnetic rod 303 and the first electromagnetic rod 302 are activated and generate strong magnetic force, magnetically connecting the workpiece to the first electromagnetic rod 302 and the second electromagnetic rod 303. When the workpiece is completed, after turning off the first electromagnetic rod 302 and the second electromagnetic rod 303, the workpiece is removed.

[0031] Refer to Figures 2-4The outer wall of the second electromagnetic rod 303 is provided with an auxiliary structure 4, and the auxiliary structure 4 includes a second rotating rod 401 rotatably connected to the end of the second electromagnetic rod 303 away from the first rotating rod 304. The size and shape of the second rotating rod 401 are the same as the size and shape of the first rotating rod 304. The outer wall of the second rotating rod 401 is movably connected to the inner wall of the base 301. The bottom wall of the second rotating rod 401 is fitted with a second connecting block 402. The shape and size of the second connecting block 402 are the same as the shape and size of the first connecting block 305. The bottom wall of the second connecting block 402 is installed with a second spring 403. The second connecting block 402 is subjected to force by the second spring 403, so that the second connecting block 402 is fitted with the second rotating rod 401. When the workpiece is subjected to force on the second electromagnetic rod 303, the second electromagnetic rod 303 drives the second rotating rod 401 and the second connecting block 402 to move downward, and the second spring 403 contracts during the movement.

[0032] One end of the second spring 403 away from the second connecting block 402 is fixedly connected to the inner wall of the base 301, and a second abutment column 404 is installed on the bottom wall of the second connecting block 402. The bottom wall of the second abutment column 404 is not in contact with the inner bottom wall of the base 301. The second abutment column 404 has a certain distance from the inner bottom wall of the base 301, and the distance is designed according to the distance generated by the first abutment column 307 pressing the switch 308 to avoid a certain offset on the left and right sides of the workpiece when force is applied.

[0033] The bottom wall of the U-shaped plate 2 is installed with table legs 5. There are two table legs 5, which are installed on both sides of the U-shaped plate 2 respectively. The bottom wall of the table legs 5 and the bottom wall of the conveyor 1 are in the same horizontal plane. The stability of the connection between the U-shaped plate 2 and the conveyor 1 is enhanced by the setting of the table legs 5.

[0034] Working principle:

[0035] The conveyor 1 is started to transport the workpiece to the U-shaped plate 2. When the workpiece contacts the first electromagnetic rod 302, the workpiece is driven by the force of the conveyor 1 to continue to move to the second electromagnetic rod 303. At this time, the workpiece is subjected to force on the second electromagnetic rod 303, driving the first rotating rod 304 and the first connecting block 305 to move downward. The first connecting block 305 drives the first spring 306 to contract, and the first abutting column 307 moves to the switch 308 position with the first connecting block 305. After the first abutting column 307 contacts the switch 308, the second electromagnetic rod 303 and the first electromagnetic rod 302 are started and generate strong magnetic force, magnetically connecting the workpiece to the first electromagnetic rod 302 and the second electromagnetic rod 303. After the workpiece reaches a specific position, the first electromagnetic rod 302 and the second electromagnetic rod 303 are automatically started to magnetically connect the workpiece, effectively avoiding the problem that the workpiece cannot be accurately fixed at a specific position, resulting in a decrease in the qualified rate of the workpiece.

[0036] When the workpiece exerts a force on the second electromagnetic rod 303, the second electromagnetic rod 303 drives the second rotating rod 401 and the second connecting block 402 to move downward. During the movement, the second spring 403 contracts. At this time, the second abutting column 404 moves downward with the second connecting block 402 and fits against the inner bottom wall of the conveyor 1, effectively preventing the workpiece from shifting left and right when a force is applied.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
