[0028] The grinding mechanism includes a driving motor 1001, which is fixedly connected to the center position of the upper end of the motor base 4. A driving shaft 1002 is fixedly connected to the right side of the driving motor 1001. One side of the driving shaft 1002 is slidably connected to the grinding box 7. A groove 1003 is provided at the right end of the driving shaft 1002. Driven by the motor base 4, the driving shaft 1002 on the driving motor 1001 can slide back and forth while rotating on the inner wall of the grinding box 7.

[0029] By setting the driving shaft 1002, when the motor seat 4 slides on the slide rod 6, the motor seat 4 drives the driving motor 1001 to move, and the driving motor 1001 drives the driving shaft 1002 to slide on the inner wall of the grinding box 7 while rotating, so as to achieve the purpose of grinding the iron core in sequence.

[0030] A first positioning rod 1004 is slidably connected to one side of the driving shaft 1002, and the first positioning rod 1004 is perpendicular to the driving shaft 1002.

[0031] By setting the first limiting block 1005, the external grinding rod 1006 drives the first positioning rod 1004 to slide on the inner wall of the driving shaft 1002. When the bottom of the first positioning rod 1004 contacts the inner wall of the driving shaft 1002, under the action of the first limiting block 1005, the first positioning rod 1004 is prevented from falling off from the inside of the groove 1003, thereby achieving the purpose of limiting the first positioning rod 1004 to slide only on the inner wall of the driving shaft 1002.

[0032] A first knob 1009 is slidably connected to the top of the outer polishing rod 1006, and a circle of anti-slip sleeve is fixedly connected to the outer side of the first knob 1009. A first screw 1010 is fixedly connected to the bottom of the first knob 1009. The outer side of the first screw 1010 is slidably connected to the outer polishing rod 1006, and the bottom of the first screw 1010 is threadedly connected to a first screw sleeve 1011. The first screw 1010 passes through the outer polishing rod 1006 and is threadedly connected to the first screw sleeve 1011. One side of the first screw sleeve 1011 is fixedly connected to the driving shaft 1002. Driven by the first knob 1009, the first screw 1010 drives the first positioning rod 1004 on the outer polishing rod 1006 to slide on the inner wall of the driving shaft 1002.

[0033] By setting the first screw 1010 and rotating the first knob 1009, the first knob 1009 drives the first screw 1010 to rotate in the first screw sleeve 1011. Under the action of the first screw 1010, the first positioning rod 1004 on the external grinding rod 1006 slides on the inner wall of the driving shaft 1002, changing the distance between the external grinding plate 1007 on the external grinding rod 1006 and the outer side of the iron core 1008, thereby achieving the purpose of grinding the outer side of the iron core of different specifications.

[0034] A second positioning rod 1012 is slidably connected to one side of the outer grinding rod 1006, and the second positioning rod 1012 is perpendicular to the outer grinding rod 1006. A second limiting block 1013 is fixedly connected to the upper end of the second positioning rod 1012, and an inner grinding rod 1014 is fixedly connected to the lower end of the second positioning rod 1012, and the inner grinding rod 1014 is perpendicular to the second positioning rod 1012. An inner grinding plate 1015 is fixedly connected to one side of the inner grinding rod 1014, and the upper end of the inner grinding plate 1015 is in contact with the iron core 1008, and the upper end of the inner grinding plate 1015 is in complete contact with the inner wall of the iron core 1008.

[0035] By setting the second positioning rod 1012 and the inner grinding plate 1015, driven by the second knob 1018, the second screw 1017 rotates inside the second screw sleeve 1016, and under the action of the second screw 1017, the second positioning rod 1012 slides on the outer grinding rod 1006, thereby changing the distance between the inner grinding rod 1014 and the outer grinding rod 1006, thereby changing the distance between the inner grinding plate 1015 on the inner grinding rod 1014 and the inner wall of the iron core 1008, thereby achieving the purpose of grinding the inner wall of the iron core of different specifications.

[0036] A second screw sleeve 1016 is fixedly connected to the top of the inner polishing rod 1014, and the internal thread of the second screw sleeve 1016 is connected to the second screw rod 1017, the upper end of the second screw rod 1017 is slidably connected to the outer polishing rod 1006, and the upper end of the second screw rod 1017 is fixedly connected to the second knob 1018, and the bottom of the second knob 1018 is slidably connected to the outer polishing rod 1006. Driven by the second knob 1018, the second screw rod 1017 drives the second positioning rod 1012 on the inner polishing rod 1014 to slide on the outer polishing rod 1006.

[0037] The inner wall of the grinding box 7 is fixedly connected with a feed plate 11, which is provided in two and respectively located below the feed hopper 8 and above the driving shaft 1002. A feed channel is formed between the two feed plates 11, and two limit grooves 12 are provided inside each feed plate 11. The limit groove 12 is internally rotatably connected with a limit rod 13, which is provided in two and respectively located at the upper and lower ends of the limit groove 12. A limit belt 14 is slidably connected to one side of the limit rod 13, and a plurality of limit blocks 15 are fixedly connected to one side of the limit belt 14. Each group of limit belts 14 has a limit block 15 on it. The two limit blocks 15 clamp an iron core 1008, the inner wall of the polishing box 7 is fixedly connected to an inclined plate 16, one side of the inclined plate 16 is fixedly connected to a discharge plate 17, and the discharge plate 17 is provided with two and respectively located on both sides of the inclined plate 16, one side of the discharge plate 17 is fixedly connected to the polishing box 7, the two discharge plates 17 and the inclined plate 16 at the bottom form a discharge channel, when the polished lever falls onto the inclined plate 16, under the restriction of the two discharge plates 17, the iron core 1008 slides along the inclined plate 16 into the discharge hopper 9, and the lower end of the inclined plate 16 is fixedly connected to the discharge hopper 9.

[0038] By setting the feed plate 11 and the limit block 15, a feed channel is formed between the feed plates 11 on both sides of the iron core 1008. When the iron core 1008 enters the feed channel from the feed hopper 8, the limit block 15 on the feed plate 11 sorts each iron core 1008 to avoid too many iron cores 1008 piling up and causing jamming. Under the action of the iron core 1008's own gravity, each iron core 1008 clamped between the two limit blocks 15 enters the clamping roller 27 at the bottom in turn to wait for grinding, thereby achieving the purpose of automatically sorting the iron cores in turn. It should be noted that a person skilled in the art can add a driving mechanism, such as a driving motor, to the end of the limit rod 13 to control the movement of the limit block 15.

[0039] A baffle 18 is rotatably connected to one side of the feed plate 11, and the upper end of the baffle 18 is rotatably connected to the feed plate 11 through a rotating shaft. The baffle 18 is set at a certain inclination, and a connecting seat 19 is fixedly connected to the bottom of the baffle 18. A connecting block 20 is rotatably connected inside the connecting seat 19, and a telescopic rod 21 is fixedly connected to the center position of the right end of the connecting block 20. One side of the telescopic rod 21 is slidably connected to the inner wall of the polishing box 7, and one end of the telescopic rod 21 is fixedly connected to a telescopic motor 22, and one side of the telescopic motor 22 is fixedly connected to the inner wall of the polishing box 7. The connecting block 20 and the connecting seat 19 are movably connected together through a rotating shaft.

[0040] By setting the baffle 18 and starting the telescopic motor 22, the telescopic motor 22 drives the telescopic rod 21 to move to the left, and the telescopic rod 21 drives the connecting block 20 to move. Under the action of the connecting block 20, the connecting seat 19 rotates around the connecting block 20 and moves to the left, so that the bottom of the baffle 18 and the inner wall of the grinding box 7 form a larger angle. The size of the angle is controlled according to the length of the iron core 1008, so that the iron core 1008 enters the interior of the clamping roller 27 in turn, thereby achieving the purpose of collecting the iron cores 1008 of different sizes.

[0041] The inner wall of the polishing box 7 is fixedly connected with a support rod 23, which is arranged in two groups and respectively located on both sides of the iron core 1008, each group of support rods 23 includes two support rods 23 and respectively located at the left and right ends of the iron core 1008, one end of each group of support rods 23 is fixedly connected with two support rings 24, and a rotating rod 25 is rotatably connected inside the support ring 24 of each group of support rods 23, and the rotating rod 25 and the support rod 23 are perpendicular to each other, and a rotating motor 26 is fixedly connected to the center position of one end of the rotating rod 25, and one side of the rotating motor 26 is fixedly connected to the polishing box 7, and two clamping rollers 27 are fixedly connected to the outer side of each rotating rod 25, and the clamping rollers 27 at the same position of each rotating rod 25 fix the iron core 1008.

[0042] By setting the clamping rollers 27 and controlling the starting sequence of the two sets of rotating motors 26, the clamping rollers 27 are staggered with each other, thereby changing the gap between the two sets of clamping rollers 27 on both sides of the iron core 1008, so that iron cores 1008 of various sizes can be fixed between the clamping rollers 27, thereby achieving the purpose of fixing iron cores 1008 of different sizes.

[0043] The working principle of this embodiment is as follows: the iron core 1008 is placed into the feed hopper 8, and the iron core 1008 falls on the limit block 15 on the feed plate 11. Each iron core 1008 is limited inside the upper and lower limit blocks 15. Under the action of gravity, the iron core 1008 falls along the feed channel onto the clamping roller 27 at the bottom of the feed plate 11, and the rotating motor 26 is started. The rotating motor 26 drives the rotating rod 25 to rotate inside the support ring 24 on the support rod 23, and the rotating rod 25 drives the clamping roller 27 to rotate. The two sets of clamping rollers 27 drive one iron core 1008 to move downward; When the center of one end of the iron core 1008 moves to the center position of the driving shaft 1002, the rotating motor 26 is turned off, the switch of the hydraulic press 2 is started, the hydraulic press 2 drives the hydraulic rod 3 to move rightward, the hydraulic rod 3 drives the sliding sleeve 5 on the motor seat 4 to slide on the sliding rod 6, and the motor seat 4 drives the driving motor 1001 to slide on the inner wall of the grinding box 7; When the grinding sheet at the right end of the driving shaft 1002 contacts the steel pipe 1008, the switch of the hydraulic press 2 is turned off, and the first knob 1009 is rotated. The first knob 1009 drives the first screw 1010 to rotate inside the outer grinding rod 1006 and the first screw sleeve 1011. Under the action of the first screw sleeve 1011, the first positioning rod 1004 on the outer grinding rod 1006 slides on the inner wall of the driving shaft 1002. When the outer grinding rod 1006 drives the outer grinding sheet 1007 to contact the outer side of the iron core 1008, the first knob 1009 is stopped from rotating, and the second knob 1018 is rotated. The second knob 1018 drives the second screw 1017 to rotate inside the outer grinding rod 1006 and the second screw sleeve 1016. Under the action of the second screw sleeve 1016, the second screw rod 1017 drives the inner grinding rod 1014 and the second positioning rod 1012 to move upward. When the inner grinding sheet 1015 on the inner grinding rod 1014 contacts the inner wall of the iron core 1008, stop rotating the knob. Under the clamping of the outer grinding sheet 1007 and the inner grinding sheet 1015, the annular section of the iron core 1008 is fixed. Then, start the drive motor 1001. The drive motor 1001 drives the drive shaft 1002 to rotate on the inner wall of the polishing box 7. The drive shaft 1002 drives the outer grinding sheet 1007 and the inner grinding sheet 1015 to polish the outer side and inner wall of the iron core 1008, so as to achieve the purpose of polishing iron cores of different specifications.

[0044] When the size of the inserted iron core 1008 is too small, the telescopic motor 22 is started, and the telescopic motor 22 drives the telescopic rod 21 to slide on the inner wall of the grinding box 7, and the telescopic drive connects the block 20 to move to the left, and the connects the block 20 drives the connective seat 19 to rotate around the center of the rotating shaft on the connective block 20 while moving to the left, and the connective seat 19 drives the baffle 18 to rotate around the rotating shaft on the baffle 18, so that the length in the feeding channel becomes shorter, thereby arranging the shorter iron core 1008 into a straight line. It should be noted that the rotation amplitude of the baffle 18 is small. The technical scheme is used to adjust the iron core 1008 with a small difference in length. First, start the switch of one of the rotating motors 26 to reduce the gap between the two sets of clamping rollers 27 until it is the same as the diameter of the iron core 1008, and then start the switch of the other rotating motor 26 to ensure that the smaller size of the iron core 1008 can be fixed between the two sets of clamping rollers 27, so as to achieve the purpose of fixing the iron cores 1008 of different sizes.

[0045] After the iron core 1008 is polished, the rotating motor 26 is started, and the rotating motor 26 drives the clamping roller 27 to rotate. The iron core 1008 in the clamping roller 27 falls down, passes through the discharge channel between the discharge plate 17 and the inclined plate 16, and rolls into the discharge hopper 9.

[0046] This scheme can add another embodiment, that is, the first knob 1009 and the second knob 1018 are replaced with a small motor for driving the first screw 1010 and the second screw 1017 to rotate, so as to increase the clamping force of the outer grinding plate 1007 and the inner grinding plate 1015 on the iron core 1008. In the above technical scheme, the rotation of the first screw 1010 and the second screw 1017 is achieved by rotating the first knob 1009 and the second knob 1018. Replacing them with a small motor can not only increase the clamping force of the outer grinding plate 1007 and the inner grinding plate 1015 on the iron core 1008, but also realize automatic control and improve the accuracy of grinding the iron core 1008.

[0047] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 6 A fixed sleeve 28 is fixedly connected to one side of the polishing box 7 , and the interior of the fixed sleeve 28 is slidably connected to the driving shaft 1002 , and the driving shaft 1002 can rotate freely inside the fixed sleeve 28 .

[0048] The working principle of this embodiment is as follows: when the driving motor 1001 drives the driving shaft 1002 to slide on the inner wall of the polishing box 7, due to the excessive length of the driving shaft 1002 and the small contact area with the inner wall of the polishing box 7, it is easy to cause the driving shaft 1002 to swing left and right when rotating. This problem can be solved by providing a fixed sleeve 28. By providing the fixed sleeve 28, when the driving motor 1001 drives the driving shaft 1002 to slide on the inner wall of the polishing box 7, the driving shaft 1002 slides inside the fixed sleeve 28. The fixed sleeve 28 increases the contact area between the driving shaft 1002 and the inner wall of the polishing box 7, and stabilizes one side of the driving shaft 1002 inside the fixed sleeve 28, thereby avoiding the problem of the driving shaft 1002 swinging left and right when rotating, thereby achieving the purpose of stabilizing the driving shaft 1002 to slide on the inner wall of the polishing box 7.
