[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 As shown, in the embodiment of the utility model, a magnetic grinding sample clamp device for a belt grinding machine includes a magnetic seat body 1, a magnetic cover body 2 and a rotating handle 3. In this embodiment, the two sides of the magnetic seat body 1 are mainly magnetic iron parts, and a non-magnetic aluminum part is embedded between the two magnetic iron parts to form the magnetic seat body 1. The magnetic seat body 1 is rotatably connected to a magnet block 11, and a rotating handle 12 is clamped on the magnet block 11;

[0023] The magnetic cover body 2 is arranged on the magnetic seat body 1, and the rotating handle 12 is rotatably connected in the magnetic cover body 2;

[0024] A rotating handle 3, which is arranged on the rotating handle 12;

[0025] When the rotating handle 12 is rotated by the rotating handle 3, the position of the magnet block 11 inside the magnetic seat body 1 is changed until the N pole and the S pole of the magnet block 11 are rotated to the position of the non-magnetic conductive part in the magnetic seat body 1 (i.e., the loose position), the magnetic force lines of the N pole and the S pole of the magnet block 11 form a closed circuit through the magnetic conductive parts on both sides, and have no adsorption force on the steel sample; when the N pole and the S pole of the magnet block 11 are rotated by the rotating handle to face the magnetic conductive iron parts on both sides of the magnetic seat body 1 respectively (i.e., the adsorption position), due to the isolation of the non-magnetic conductive parts, the magnetic force lines of the N pole of the magnet block 11 cannot effectively reach the S pole. At this time, when the steel sample approaches the magnetic seat body 1, the magnetic force lines of the N pole and the S pole of the magnet block 11 form a closed circuit through the steel sample, and the steel sample is tightly adsorbed;

[0026] By rotating the handle 3 in real time, the rotating handle 12 is rotated to change the position of the magnet block 11 inside the magnetic seat body 1 to the adsorption position, so that the bottom of the magnetic seat body 1 can adsorb and fix the sample parts in real time. After the adsorption is completed, the staff will fix the entire sample fixture above the sanding belt of the grinder to grind the sample parts fixed below it. After the grinding is completed, the sample fixture is removed as a whole, and the rotating handle 12 on the magnetic cover body 2 is rotated again to change the position of the magnet block 11 inside the magnetic seat body 1 to a loose position. The device uses the principle of magnetic adsorption to firmly clamp the workpiece at the bottom of the magnetic seat body 1, simplifies the operation process of sample fixing, and is convenient to operate when replacing the sample. The sample can be tightly adsorbed on the bottom of the magnetic seat body by using the principle of magnetic adsorption, which avoids the sample being ground on the sanding belt of the grinder for too long, and the sample parts clamped on the fixture are easy to loosen, and the sample falls off.

[0027] In one embodiment, see Figure 1 and Figure 3 As shown, the rotating handle 12 includes a mounting column 121 and a clamping portion 122. The mounting column 121 is rotatably connected in the magnetic cover body 2. A rotating handle 3 is provided on the mounting column 121. The bottom of the mounting column 121 is fixedly connected with a clamping portion 122. The clamping portion 122 is clamped on the magnet block 11. The magnet block 11 is provided with a clamping groove matching the size of the clamping portion 122. The clamping portion 122 is clamped in the magnet block 11, which is convenient for the entire staff to rotate the mounting column 121 on the magnetic cover body 2 and drive the magnet block 11 to rotate in the mounting base body 1 through the clamping portion 122, thereby facilitating the magnetic base body 1 to absorb or loosen the sample at its bottom.

[0028] In one embodiment, see Figure 1 and Figure 2 As shown, the magnetic cover body 2 is connected to the magnetic base body 1 through a plurality of screws. Specifically, the magnetic cover body 2 and the magnetic base body 1 are connected through screws, which facilitates the disassembly and installation of the magnetic cover body 2.

[0029] In one embodiment, see Figure 1 and Figure 2 As shown, two identification plates 4 are also provided on the magnetic cover body 2. The two identification plates 4 respectively record the start position and the close position, so that the staff can easily identify whether the magnetic clamp is in the open state or the closed state.

[0030] In one embodiment, see Figure 1 and Figure 3 As shown, the rotating handle 3 is provided with anti-slip grooves 31 to facilitate the operator to rotate the rotating handle 12.

[0031] In one embodiment, see Figure 1 and Figure 3 As shown, a threaded hole 32 is provided on the rotating handle 3, and the rotating handle 3 is detachably connected to the rotating handle 12. The rotating handle 3 and the rotating handle 12 are connected by threads, which is convenient for disassembly and installation.
