[0022] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] See also Figures 1 to 8 As shown, the utility model is a fixing mechanism for facilitating magnet cutting, comprising a fixing device 1, the fixing device 1 comprising a fixed base plate 2, a fixed upper plate 3 placed on the fixed base plate 2, and a plurality of positioning blocks 4 arranged on the fixed base plate 2; the positioning blocks 4 protrude from the upper surface of the fixed base plate 2, the positioning blocks 4 are movably connected to the fixed base plate 2, and a plurality of positioning blocks 4 are arranged on the fixed base plate 2 to form a limiting groove 5, which accommodates the fixed upper plate 3.

[0024] Specifically, the positioning block 4 is provided with a first connecting portion 401. The first connecting portion 401 is located on the portion of the positioning block 4 that protrudes from the upper surface of the fixed base plate 2. The first connecting portion 401 contacts the side of the fixed upper plate 3, and the fixed upper plate 3 is fixed within the limiting groove 5 via the first connecting portion 401. In this embodiment, the magnet is fixed to the fixed upper plate 3 by glue; the first connecting portion 401 is a meshing connection between a gear and a rack. The gear is mounted on one end of a torsion member, and twisting the torsion member drives a push rod mounted with a matching rack. In actual use, a technician twists the torsion member to drive the push rod back outside the limiting groove 5, places the fixed upper plate 3 with the magnet fixed in the limiting groove 5, and then twists the torsion members provided on multiple positioning blocks 4 in sequence to drive the push rod against the side of the fixed upper plate 3, thereby securing the fixed upper plate 3. In this embodiment, the first connecting portion 401 can also be a rotational connection combination of a threaded hole and a screw rod. During actual use, the technician first places the fixed upper plate 3 with the magnet fixed thereon into the limiting groove 5 , and then rotates the screw rod through the threaded hole to abut against the side surface of the fixed upper plate 3 , thereby fixing the fixed upper plate 3 .

[0025] In this embodiment, the first connecting portion 401 can also be a spring button structure. In actual use, the technician first places the fixed upper plate 3 fixed with the magnet in the limiting groove 5, and the technician presses the first button 4011 while the first button 4011 squeezes the metal spring 4013, and the first button 4011 indirectly pushes out the ejector rod 4016. The technician withdraws the pressure on the first button 4011, and the first spring 4014 pushes the ejector rod 4016 back in the opposite direction. At this time, the metal spring 4013 is stuck in the buckle position, causing the ejector rod 4016 to protrude out of the positioning block 4 and contact the fixed upper plate 3. The side of plate 3 cannot move, so the upper plate 3 is fixed; when the technician needs to remove the fixed upper plate 3, the technician first presses the second button 4012. While pressing the second button 4012, the second button 4012 squeezes the metal spring 4013. Under the buffering protection of the second spring 4015, the metal spring 4013 leaves the buckle position. At the same time, the push rod 4016 retracts the positioning block 4 under the push of the first spring 4014, completing the resetting of the spring button, and the technician then removes the fixed upper plate 3.

[0026] In this embodiment, the length of the fixed upper plate 3 is no greater than the length of the limiting slot 5, and the width of the fixed upper plate 3 is no greater than the width of the limiting slot 5. In actual production, if the length of the fixed upper plate 3 is greater than the length of the limiting slot 5 or the width of the fixed upper plate 3 is greater than the width of the limiting slot 5, the fixed upper plate 3 will interfere with the positioning block 4, and the fixed upper plate 3 cannot be fixed.

[0027] Specifically, the fixed base plate 2 includes a first base plate 201, which is provided with a clearance groove 203. The clearance groove 203 is located on the side of the first base plate 201. The clearance groove 203 cooperates with the external mounting seat. The clearance groove 203 accommodates the external mounting seat for controlling the movement of the fixed base plate 2. In this embodiment, there are four clearance grooves 203, two of which are symmetrically located on both sides of the first base plate 201. The clearance grooves 203 are provided with through holes with a diameter of 10 mm. The through holes are used to cooperate with the external mounting seat, and the external mounting seat is an M8 screw. During actual production, technicians use M8 screws to cooperate with the through holes in the clearance grooves 203. The M8 screws pass through the through holes to securely connect to the external base, thereby fixing the fixed base plate 2 to the external base.

[0028] Specifically, the fixed base plate 2 also includes a second base plate 202, which protrudes from the upper surface of the first base plate 201. The first base plate 201 and the second base plate 202 are fixedly connected. A symmetrical first step 204 is formed on both sides of the fixed base plate 2, and the first step 204 reveals a clearance groove 203. In this embodiment, the maximum cross-sectional area of the first base plate 201 is greater than the maximum cross-sectional area of the second base plate 202. The length of the first base plate 201 is 460 mm, and the width of the first base plate 201 is 220 mm; the length of the second base plate 202 is 460 mm, and the width of the second base plate 202 is 160 mm. The fixed base plate 2 can be removed or installed. An Allen wrench is used during the removal or installation of the fixed base plate 2 to avoid interference with the first base plate 201. In actual use: the Allen wrench enters the clearance groove 203 and engages the hexagon of the screw rod installed in the through hole of the clearance groove 203. Turning the Allen wrench can move the screw rod, thereby achieving installation or removal of the fixed base plate 2.

[0029] In this embodiment, the maximum cross-sectional area of the first substrate 201 can also be equal to the maximum cross-sectional area of the second substrate 202. The length of the first substrate 201 is 460 mm, and the width of the first substrate 201 is 220 mm; the length of the second substrate 202 is 460 mm, and the width of the second substrate 202 is 220 mm. Four through-grooves 2021 are provided on the second substrate 202. The four through-grooves 2021 are respectively located above the four air-avoidance grooves 203, and the through-grooves 2021 reveal the air-avoidance grooves 203. In actual use: the hexagonal wrench passes through the through-grooves 2021 and enters the air-avoidance groove 203, and clamps the hexagonal socket of the screw rod that is installed in conjunction with the through-hole of the air-avoidance groove 203. The screw rod can be moved by turning the hexagonal wrench, thereby achieving the installation or disassembly of the fixed substrate 2.

[0030] Specifically, the fixed upper plate 3 includes a first upper plate 301 and a second upper plate 302 fixedly connected to the first upper plate 301. The upper surface of the second upper plate 302 is fixedly connected to the magnet. The first upper plate 301 protrudes and is arranged on the lower surface of the second upper plate 302. A symmetrical second step 303 is formed on both sides of the fixed upper plate 3 to form a stepped structure. In this embodiment, the fixed upper plate 3 is a marble plate, the dimensions of the second upper plate 302 are 460 mm in length and 220 mm in width, the dimensions of the first upper plate 301 are 460 mm in length and 180 mm in width, the overall thickness of the fixed upper plate 3 is 22 mm, and the magnets are glued to the fixed upper plate 3 with glue; in actual use: if the fixed upper plate 3 has no stepped structure, the technician will carry the fixed upper plate 3 filled with magnets to the fixed base plate 2, and the technician's fingers will be on the surface of the first upper plate 301, which may easily cause accidents of crushing fingers; if the fixed upper plate 3 is provided with a second step 303, the technician can use the second step 303 as a force-bearing position for carrying, and the second step 303 can accommodate the technician's fingers to avoid accidents of crushing fingers.

[0031] Specifically, the upper surface of the second upper plate 302 is recessed with diversion channels 402. These channels are recessed into the second upper plate 302 and are used to drain coolant. The diversion channels 402 extend through opposing sides of the second upper plate 302. Multiple diversion channels 402 are arranged in a rectangular array on the second upper plate 302. In this embodiment, the diversion channels 402 are 3 mm wide and 3 mm deep, with a 5 mm distance between adjacent diversion channels 402. In actual use, during the magnet cutting process, coolant flows across the magnet surface, enters the second upper plate 302, and then exits the second upper plate 302 through the diversion channels 402.

[0032] Specifically, the second upper plate 302 is further provided with a positioning channel 403 . The positioning channel 403 is located on opposite sides of the second upper plate 302 , and the positioning channel 403 accommodates the first connecting portion 401 .
