[0029] Combine the following Figure 1-6 The present invention is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front, and back directions mentioned below are the same as Figure 1 The view direction is consistent in front, back, left, right, up and down directions. Figure 1 The directions shown are consistent with the front, back, left, right, up and down directions of the device of the present invention when viewed from the front.

[0030] See also Figure 1-6The present invention provides an embodiment: a multi-angle grinding device for silicon steel coil core, comprising an outer mold shell 10 and an outer mold shell 2 11, wherein the arc-shaped ends of the outer mold shell 10 and the outer mold shell 2 11 are hinged, and the straight plate ends of the outer mold shell 10 and the outer mold shell 2 11 are detachably connected, so that the outer mold shell 10 and the outer mold shell 2 11 form an outer mold shell, which can cover the silicon steel coil core 5. When in use, only the A end needs to be opened to wrap the core column of the silicon steel coil core 5. A long slide groove 14 is provided at the straight plate end of the outer mold shell 2 11, and a cylindrical portion 17 is installed in the long slide groove 14. The cylindrical portion 1 7 is rotatably connected with a rotating inner core 18, and a flexible shaft 12 is fixedly connected to the rotating inner core 18. The end of the flexible shaft 12 extending outside is connected to the output end of the motor 19 through a connector, wherein the connector is a quick-release transmission connector, which can be a coupling, to ensure that the flexible shaft 12 and the motor 19 can be quickly released. The flexible shaft 12 can be bent at will and change its shape or direction without losing functionality. At the same time, a number of cylindrical quartz grinding wheels 30 are distributed and installed on the flexible shaft 12. The number of cylindrical quartz grinding wheels 30 is determined according to the grinding surface 6 on the surface of the silicon steel coil core 5, referring to Figure 5 , it can be seen that there are nine grinding surfaces 6. At this time, nine cylindrical quartz grinding wheels 30 need to be installed on the flexible shaft 12, and each cylindrical quartz grinding wheel 30 corresponds to a grinding surface 6. At this time, the flexible shaft 12 is inside the outer mold shell formed by the outer mold shell 10 and the outer mold shell 2 11, as an inner mold. Due to the characteristics of the flexible shaft 12, the flexible shaft 12 can fit on the core column of the silicon steel coil core 5 and bend around the shape of the core column. After the flexible shaft 12 wraps the core column, since the total length of the flexible shaft 12 is fixed, it is possible to judge whether the silicon steel coil core 5 is qualified according to a position of the C end of the tail of the flexible shaft 12, thereby realizing a detection of the silicon steel coil core 5. After the flexible shaft 12 wraps the silicon steel coil core 5, the cylindrical quartz grinding wheel 30 also fits between the corresponding grinding surfaces 6, and the cylindrical quartz grinding wheel 30 is used to grind each grinding surface 6 of the silicon steel coil core 5;

[0031] It is worth mentioning that in order to effectively ensure stability and uniformity during grinding, in the present embodiment, strip holes 13 are respectively provided on the outer mold shell 10 and the outer mold shell 2 11, wherein the positions of the strip holes 13 correspond to the cylindrical quartz grinding wheels 30 respectively, and a strip hole 13 is provided at a certain interval, and a stabilizing mechanism 40 is respectively installed in each of the strip holes 13, and the stabilizing mechanism 40 includes a connecting portion 41, and side plates 44 are respectively fixedly installed on both sides of the connecting portion 41, and two ceramic rollers 45 are rotatably connected between the two side plates 44, and the two ceramic rollers 45 are symmetrically distributed about the center line of the connecting portion 41, so that the two ceramic rollers 45 abut against the corresponding cylindrical quartz grinding wheels 30 to press the cylindrical quartz grinding wheels 30, while maintaining the overall stability of the flexible shaft 12, which can effectively avoid the grinding process. The flexible shaft 12 is unstable, and the connecting part 41 is installed in each of the strip holes 13 in an adjustable manner, wherein a rivet nut 42 is installed on the connecting part 41, and the tail end of the rivet nut 42 passes through the mounting hole in the connecting part 41, and is rotatably connected to the connecting part 41, exposing the friction pattern of the rivet nut 42 near the head end, and at the same time, a bolt 43 is used to pass through the strip hole 13 from the outside, and then threadedly connected to the threaded hole at the head end of the rivet nut 42, wherein a gasket 46 is also sleeved on the bolt 43, and the gasket 46 abuts against the edge of the outer side of the strip hole 13, so that it can be loosened by rotating the bolt 43, and then the position can be slidably adjusted along the strip hole 13 without loosening the bolt 43. The rivet nut 42 can be rotated from the inside to fine-tune the distance between the ceramic roller 45 and the cylindrical quartz grinding wheel 30.

[0032] It is also worth mentioning that, in order to facilitate the installation of the drive source or the replacement of different drive sources, in the present embodiment, a quick-release assembly 20 is fixedly installed on the straight plate end of the outer mold shell 10, wherein the quick-release assembly 20 includes a horizontal bar 21 fixedly installed on the outer mold shell 10, and an arc-shaped clamping plate 22 is fixedly connected to the horizontal bar 21, and a threaded cap 25 is connected to the top of the arc-shaped clamping plate 22, and an arc-shaped clamping plate 23 is hinged to the bottom of the arc-shaped clamping plate 22, and a threaded shaft 24 is fixedly installed on the top of the arc-shaped clamping plate 23, and the threaded shaft 24 can be threadedly connected to the threaded cap 25, and a pinching plate 26 is fixedly connected to the outer end face of the threaded shaft 24, and friction grooves are distributed on the pinching plate 26, and the motor 19 is installed between the arc-shaped clamping plate 22 and the arc-shaped clamping plate 23, and quick opening or locking can be achieved by rotating the threaded shaft 24.

[0033] It should be noted that in order to further facilitate the detection of the size of the silicon steel coil core 5 using the flexible shaft 12, in the present embodiment, a mounting plate 16 is slidably installed in the long slide groove 14, and a stabilizing mechanism 40 is fixedly installed on the mounting plate 16. At the same time, a size scale is marked on the outer edge of the long slide groove 14, so that the tail end C of the flexible shaft 12 is clamped between the two ceramic rollers 45 to ensure that the tail end C of the flexible shaft 12 is in the position between the two ceramic rollers 45. At this time, the size scale corresponding to the position of the mounting plate 16 can be observed, so that it is possible to effectively observe whether the size of the silicon steel coil core 5 meets the standard, thereby effectively improving the grinding efficiency and grinding accuracy.

[0034] It should also be noted that a retaining spring 31 is installed at both side end surfaces of each cylindrical quartz grinding wheel 30 , so as to effectively ensure the position of the cylindrical quartz grinding wheel 30 and prevent the cylindrical quartz grinding wheel 30 from sliding horizontally.

[0035] In addition, in one embodiment, handles 15 are fixedly installed on the outer end faces of the outer mold shell 10 and the outer mold shell 2 11, and each of the handles 15 is respectively close to the straight plate ends of the outer mold shell 10 and the outer mold shell 2 11. At the same time, rubber pads can be put on the handles 15 for shock absorption, so that workers can hold the handles 15 with both hands, thereby driving the equipment to grind the silicon steel coil core 5.

[0036] In the initial state, the straight plate ends A of the outer mold shell 10 and the outer mold shell 2 11 are not fixedly connected, and the flexible shaft 12 and the motor 19 are not connected, and the flexible shaft 12 is also in an open state.

[0037] When the silicon steel coil core 5 needs to be polished, first use the gantry to lift the silicon steel coil core 5, and then use the opened outer mold shell 10 and the outer mold shell 2 11 to wrap the core column part of the silicon steel coil core 5, then fix the straight plate end A, and then connect the flexible shaft 12 to the motor 19, and then pull the flexible shaft 12 around the core column to fit it, so that each of the cylindrical quartz grinding wheels 30 is tightly attached to the polishing surface 6, and finally install the tail end C of the flexible shaft 12 in the stabilizing mechanism 40 located on the mounting plate 16, slide the mounting plate 16 to tighten the flexible shaft 12, so that the size of the steel coil core 5 can be intuitively seen through the scale on the outer edge of the long slide groove 14, so as to preliminarily judge whether the steel coil core 5 is qualified, and then polish it again, after sliding the mounting plate 16 to tighten the flexible shaft 12, observe whether each of the cylindrical quartz grinding wheels 30 is in line with the corresponding The ceramic rollers 45 are in contact with each other, and no adjustment is made to allow the ceramic rollers 45 to fully contact the cylindrical quartz grinding wheel 30. At this time, the motor 19 is started to drive the flexible shaft 12 to rotate, thereby driving each cylindrical quartz grinding wheel 30 to grind the grinding surface 6. The ceramic rollers 45 are used to stabilize the flexible shaft 12 to ensure the uniformity of grinding. At the same time, the worker holds the handle 15 and evenly moves around the silicon steel coil core 5 to grind it, so that the silicon steel coil core 5 can be quickly grinded, which greatly improves the grinding efficiency. Compared with the traditional manual use of an angle grinder to grind each surface, it not only improves the grinding efficiency, but also improves the grinding quality and the grinding uniformity. At the same time, the size of the silicon steel coil core 5 can be preliminarily detected and judged to see whether it meets the specifications, which greatly improves the work efficiency and the factory quality of the silicon steel coil core 5.

[0038] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited to it. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope defined in the claims.
