[0016] The following further describes the present application in detail with reference to the attached Figures 1 - 3 drawings.

[0017] The embodiment of the present application discloses a material positioning structure for a surface grinding machine, including a grinding machine body 1, an electromagnetic chuck 2 is arranged on the grinding machine body 1, a metal seat 3 is placed on the upper surface of the electromagnetic chuck 2, a cylindrical groove 4 is opened at the center of the metal seat 3, a cylinder 5 is arranged inside the cylindrical groove 4, a slider 7 is fixedly connected to the middle of the outer surface of the cylinder 5, a chute 10 adapted to the slider 7 is opened on the surface of the metal seat 3, the slider 7 can move up and down inside the chute 10, a bolt 6 is inserted into the slider 7, the bolt 6 is arranged along the radial direction of the cylinder 5, and one end of the bolt 6 penetrates through the side wall of the cylinder 5 and extends into the inside of the cylinder 5.

[0018] Furthermore, multiple groups of the slider 7, the chute 10, and the bolt 6 are provided, and the slider 7, the chute 10, and the bolt 6 are all distributed in a circular array with the cylinder 5 as the axis.

[0019] In this embodiment, when machining a cylindrical part, the worker places the workpiece inside the cylinder 5 and positions the cylinder 5 in the middle of the workpiece. Then, the bolts 6 are tightened in sequence so that the bolts 6 abut against the outer surface of the workpiece to fix the workpiece. Next, the metal seat 3, the cylinder 5, and the workpiece are placed on the upper surface of the electromagnetic chuck 2. Due to the action of its own gravity, the metal seat 3 moves relative to the slider 7, the cylinder 5, and the workpiece. The lower surfaces of the metal seat 3 and the workpiece are in contact with the electromagnetic chuck 2, thereby increasing the adsorption area to prevent the workpiece from tipping over during grinding. After one end of the workpiece is machined, it is only necessary to remove the metal seat 3, the cylinder 5, and the workpiece from the electromagnetic chuck 2, then turn over the metal seat 3, the cylinder 5, and the workpiece so that the other end of the workpiece faces upward, and then place them on the electromagnetic chuck 2 again. Similarly, due to the action of its own gravity, the metal seat 3 moves downward to contact the electromagnetic chuck 2, strengthening the stability of the workpiece.

[0020] Further, guide rods 8 are inserted on both sides of the slider 7. The guide rods 8 are fixedly installed inside the chute 10, and the guide rods 8 are parallel to the moving direction of the slider 7. Springs 9 are sleeved on the surfaces of the guide rods 8. One end of each spring 9 is fixedly connected to the slider 7, and the other end of each spring 9 is fixedly connected to the inner surface of the chute 10.

[0021] Further, the two groups of guide rods 8 on the slider 7 are arranged symmetrically with respect to the axis of the bolt 6.

[0022] In this embodiment, by providing the springs 9, the slider 7 and the cylinder 5 can be supported to prevent the slider 7 and the cylinder 5 from shaking and colliding with the metal seat 3 during the transportation or transfer of the metal seat 3, resulting in damage to the metal seat 3, the slider 7, and the cylinder 5.

[0023] Further, multiple sets of anti-slip lines are provided on the upper surface of the electromagnetic chuck 2. The anti-slip lines can increase the roughness of the surface of the electromagnetic chuck 2, thereby further improving the stability of the workpiece when it is located on the upper surface of the electromagnetic chuck 2.
