Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] In the embodiment, the electromagnetic chuck type automobile part positioning device comprises a base 100 and an electromagnetic chuck body 200 mounted on the top of the base 100. Figures 1-4 As shown in the figure, the positioning mechanism 300 further comprises an abutting block 330 arranged below the positioning block 320.

[0022] As shown in the figure, the positioning mechanism 300 further comprises an abutting block 330 arranged below the positioning block 320. Figure 3 As shown in the figure, the positioning mechanism 300 further comprises an abutting block 330 arranged below the positioning block 320.

[0023] When the special-shaped part is positioned, it can be placed on the electromagnetic chuck body 200 in the appropriate position, and then the electromagnetic chuck body 200 is operated to preliminarily magnetically fix the special-shaped part. Then the user can adjust the transverse position and longitudinal position of the folding rod 310 to drive the positioning block 320 to press the appropriate position of the upper surface of the special-shaped part. When the positioning block 320 contacts the surface of the special-shaped part, the second semicircular plate 322 will preliminarily adapt to the shape of the surface of the special-shaped part. Then the second semicircular plate 322 that is in contact with the second semicircular plate 322 will press the first semicircular plate 321 to adapt to the movement of the first semicircular plate 321. In this way, the adhesion effect between the positioning process and the following part surface is improved, thereby improving the positioning stability and reducing the accidental shaking phenomenon during positioning. After the pressing operation is completed, the user can use the contact block 330 to contact and fix the lower surface of the special-shaped part. Through the upper pressing and lower contact, the auxiliary fixing during the operation of the electromagnetic chuck body 200 is completed.

[0024] Even if the electromagnetic chuck body 200 is powered off and damaged accidentally, the positioning block 320 and the contact block 330 can still position the special-shaped part, reducing the phenomenon of instant loss of control of the special-shaped part.

[0025] As shown in Figure 1 , Figure 2 and Figure 3 , one end of the folding rod 310 penetrates and is slidingly connected with the vertical rod 311. The bottom end of the vertical rod 311 is provided with a piston plate 312. The outer side of the piston plate 312 is provided with a piston tube 313 which is slidingly connected with the piston plate 312. The piston tube 313 is provided with a horizontal tube 314. The outer side of the horizontal tube 314 is provided with a valve 315.

[0026] The user can pull the folding rod 310 up and down to drive the piston plate 312 to move inside the piston tube 313. When the folding rod 310 is in place, the user can close the valve 315 to prevent the gas inside the piston tube 313 from flowing to the outside through the horizontal tube 314, thereby locking the piston plate 312, ensuring the stability of the folding rod 310 and the positioning block 320. When the positioning needs to be cancelled, the valve 315 is opened, and then the folding rod 310 is removed.

[0027] As shown in Figure 1 , Figure 2 and Figure 3 , the outer side of the piston tube 313 is provided with a lead screw 316 through a hinge seat. The outer side of the lead screw 316 is provided with a threaded tube 317 which is threadedly connected with the lead screw 316. The threaded tube 317 and the contact block 330 are provided with balls therebetween. The folding rod 310 and the positioning block 320 are also provided with balls therebetween.

[0029] When the positioning block 320 completes the pressing work, the user can move the threaded pipe 317 to the appropriate angle, and then rotate the threaded pipe 317 to drive the resisting block 330 to abut against the outside surface of the special-shaped part, so as to complete the auxiliary positioning with the positioning block 320.

[0030] As shown in Figure 1 The top of the electromagnetic chuck body 200 is provided with two protective boxes 210, the inside of the protective box 210 is provided with an electric push rod 211, one end of the electric push rod 211 is fixedly connected with the outside of the piston pipe 313, one end of the piston pipe 313 is slidably connected to the inside of the protective box 210, and the materials of the protective box 210, the lead screw 316 and the threaded pipe 317 are all aluminum alloy.

[0031] The protective box 210, the lead screw 316 and the threaded pipe 317 made of aluminum alloy are used to reduce the influence of the electromagnetic on the electric push rod 211, the lead screw 316 and the threaded pipe 317.

[0032] The user can drive the electric push rod 211 to drive the piston pipe 313 to move to the machining area, and flexibly adjust according to the size of the part and the to-be-positioned area.

[0033] As shown in Figure 1 and Figure 2 The folding rod 310 and the vertical rod 311 are connected by bolts, and a group of butt joints are formed in the folding rod 310.

[0034] After the user adjusts the position of the folding rod 310 according to the size of the part, the user can connect the butt joint of the corresponding position by bolts to ensure the stability of the folding rod 310.
