Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In order to achieve the above-mentioned purpose of the invention, the utility model provides

[0039] A double-end surface grinder for magnet processing and grinding, comprising:

[0040] A gantry support 8 and a base 7 at the bottom of the gantry support 8;

[0041] The sliding frame 2 is inserted into the interior of the gantry bracket 8, and sliding components are provided at the connection between the two ends of the sliding frame 2 and the gantry bracket 8;

[0042] A power control cabinet 5 is installed on the right side of the gantry bracket 8, and the power control cabinet 5 is installed and connected to the gantry bracket 8 through the bracket 4;

[0043] A grinding motor 3 is sleeved and fixed at the middle position of the sliding frame 2, and one end of the grinding motor 3 is drivingly connected to a grinding wheel 11;

[0044] The grinding motor 3 and the dust collecting mechanism 6 are both electrically connected to the power control cabinet 5. When working, the power is turned on, and the grinding motor 3 starts to rotate, and then drives the grinding wheel 11 to rotate through the transmission shaft to grind the magnet raw material;

[0045] A clamping mechanism 10 is provided at a middle position inside the gantry support 8 .

[0046] In this technical solution, preferably

[0047] The clamping mechanism 10 includes a rubber pad 12, a clamping portion 13, a clamping screw 14, a clamping handwheel 15 and a clamping support frame 16. One end of the clamping support frame 16 is fixedly connected to the gantry support 8, and the other end is located at the middle position of the gantry support 8. A threaded tube is provided at one end located at the middle position of the gantry support 8. The clamping screw 14 is inserted into the threaded tube. The clamping handwheel 15 is connected to one end of the clamping screw 14. The other unit of the clamping screw 14 is connected to the clamping portion 13 on the inner side of the clamping support frame 16. The rubber pad 12 is connected to the arc-shaped inner groove of the clamping portion 13.

[0048] There are two clamping mechanisms 10, and the clamping parts 13 in the two clamping mechanisms 10 are correspondingly arranged to form an arc clamp;

[0049] When working, first turn the clamping hand wheel 15 to screw and rotate the clamping screw 14 and the threaded tube of the clamping support frame 16, so that the clamping screw 14 moves outward, so that the positions of the clamping parts 13 on the two clamping support frames 16 are all moved outward, increasing the distance between the two clamping parts 13, and then place the magnetic workpiece to be polished in the middle of the two clamping parts 13, and then reversely rotate the clamping hand wheel 15 again, so that the two clamping parts 13 move closer to the middle, and then contact the magnetic workpiece, and clamp the magnetic workpiece in the middle of the two clamping parts 13, and because the clamping screw 14 and the threaded tube of the clamping support frame 16 are in close contact, the clamping screw 14 will not loosen after clamping without the rotation of the clamping hand wheel 15. And because the inner arc position of the two clamping parts 13 is provided with rubber pads 12, the rubber pads 12 are used to contact the magnetic workpiece during clamping to prevent the metal clamping part 13 from causing damage to the magnetic workpiece;

[0050] In this technical solution, preferably

[0051] A lifting screw 9 is inserted into the upper end of the gantry bracket 8, and a bearing is provided at the connection between the lifting screw 9 and the gantry bracket 8. The lifting screw 9 rotates relative to the bearing, and the lifting screw 9 is connected to the transmission rod of the sliding frame 2; a threaded sleeve is provided at the connection between the sliding frame 2 and the lifting screw 9, and the threaded sleeve is sleeved on the outside of the lifting screw 9, and a lifting handwheel 1 is provided on the top of the lifting screw 9. The two sliding frames 2 are respectively sleeved with the upper and lower ends of the lifting screw 9 through threaded sleeves. There are threads in the threaded sleeves on the two sliding frames 2, and the internal threads of the two threaded sleeves are in opposite directions;

[0052] During operation, the motor 3 starts to rotate at high speed after being started, driving the two grinding wheels 11 to rotate at high speed. Since the magnetic workpiece has been clamped and fixed in the middle of the two clamping mechanisms 10 and is located in the middle position of the two grinding wheels 11, the two sliding frames 2 are respectively sleeved with the upper and lower ends of the lifting screw 9 through threaded sleeves, and the threaded sleeves on the two sliding frames 2 are threaded, and the internal threads of the two threaded sleeves are in opposite directions. Therefore, when the lifting screw 9 is driven to rotate by the lifting handwheel 1, since the upper end of the lifting screw 9 is connected to the gantry bracket 8 through a bearing, the lifting screw 9 can only rotate and cannot be located. At this time, the two sliding frames 2 sleeved on the lifting screw 9 through the threaded sleeve begin to move up and down under the rotation of the lifting screw 9. Since the internal threads of the two threaded sleeves are in opposite directions, when the lifting screw 9 rotates, the two threaded sleeves will move in opposite directions and move toward the clamping mechanism 10 at the middle position at the same time. When the grinding wheel 11 contacts the clamping mechanism When the magnetic workpiece is clamped inside the structure 10, the high-speed rotating grinding wheel 11 grinds the surface of the magnetic workpiece. During the grinding process, the lifting hand wheel 1 can continue to be rotated so that the grinding wheel 11 continues to approach the magnetic workpiece. After the grinding is completed, the lifting hand wheel 1 is reversed to make the two grinding wheels 11 move outward in opposite directions respectively, and then the clamping hand wheel 15 is reversed to move the two clamping parts 13 outward to take out the polished magnetic workpiece. If only one side of the magnetic workpiece needs to be polished, it is necessary to move it upward a little when placing the magnetic workpiece. At this time, the upper workpiece protrudes more from the clamping part 13, so when the two grinding wheels 11 are close to each other, the upper grinding wheel 11 will first contact with the upper surface of the workpiece for grinding, while the lower grinding wheel 11 cannot contact with the lower surface of the workpiece, thereby realizing single-sided grinding. The two grinding wheels 11 are controlled simultaneously by a lifting screw 9 for double-sided grinding, which is more efficient and can be rotated and adjusted at any time according to the lifting screw 9.

[0053] In this technical solution, further, preferably

[0054] There are two sliding frames 2, and both ends of the two sliding frames 2 are connected to the gantry bracket 8 through a sliding assembly; the sliding assembly includes a sliding groove 21, a sliding block 22 and a sliding ball 23, the sliding groove 21 is located inside the connection between the gantry bracket 8 and the sliding frame 2, and the sliding block 22 is inserted into the sliding groove 21, and the sliding block 22 and the inner wall contact surface of the sliding groove 21 are embedded with sliding balls 23, and the sliding balls 23 can roll. When the sliding frame 2 moves up and down, the sliding blocks 22 arranged at both ends thereof move up and down in the sliding grooves 21 of the gantry brackets 8 on both sides, and because the sliding blocks 22 and the inner wall contact surface of the sliding groove 21 are embedded with sliding balls 23, the sliding balls 23 can roll, so when moving, the rolling of the sliding balls 23 is utilized to make the contact surface smoother and the sliding smoother, so that when performing grinding adjustment, the adjustment is more convenient and the accuracy is higher;

[0055] In the present technical solution, further, a dust collecting mechanism 6 is preferably provided on the right side of the gantry bracket 8 and located on the base 7 .

[0056] The dust collecting mechanism 6 includes a dust collecting box 17, an induced draft fan 18, a filter 19, an air outlet 20 and an induced draft duct 24. The induced draft fan 18 is arranged inside the dust collecting box 17, and the air outlet 20 is arranged on one side of the dust collecting box 17 and located on the right side of the induced draft fan 18. The filter 19 is arranged on the other side of the induced draft fan 18 inside the dust collecting box 17. The induced draft duct 24 is connected to the dust collecting box 17, and the other end of the induced draft duct 24 is plugged into the gantry bracket 8, and the position corresponds to the clamping mechanism 10. When grinding, the dust will be broken. At this time, the induced draft fan 18 will generate wind absorption, and absorb the debris generated during grinding into the dust box 17 through the induced draft duct 24, and the induced draft fan 18 is provided with a filter 19 for protection, so the inhaled debris will not enter the interior of the induced draft fan 18. In the later stage, it is only necessary to open the dust box 17 regularly to take out and clean the collected debris, and the integrated mechanism 6 is used to absorb and collect the grinding debris, so as to avoid the debris from floating around and causing environmental pollution, making the equipment more environmentally friendly.

[0057] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
