[0002] Brush wire, also known as copper brush wire, is a soft connecting wire used for connecting motors, electrical appliances and instrument lines. Due to the material characteristics of copper wire, its surface needs to be polished before it is used in actual production to remove the oxide film formed by chemical reaction when the surface is exposed to the air, so that the conductivity of the copper wire remains in the best state.

[0003] The Chinese utility model patent with publication number CN216298872U discloses a wire core grinding device for electric brush wire processing, including a base plate, a wire-releasing mechanism is arranged at the left end of the top of the base plate, a grinding mechanism is arranged in the middle of the top of the base plate, and a winding mechanism is arranged at the right end of the top of the base plate. The grinding mechanism includes a mounting seat, a grinding tube is installed on the mounting seat, a countersunk hole is arranged on the outer wall of the grinding tube, a mounting groove is arranged on the inner wall of the grinding tube, a fixing block is arranged in the mounting groove, a spring is arranged at one end of the fixing block, a fixing seat is arranged at one end of the spring, a grinding seat is inserted at one end of the fixing seat, a contoured curved surface is arranged at one end of the grinding seat, and grinding sandpaper is arranged on the contoured curved surface. By using multiple sandpaper sheets to replace the traditional sandpaper tube, and pasting the sandpaper sheets on the grinding seat in the grinding mechanism that is easy to disassemble and assemble, when replacing the sandpaper, only the grinding seat needs to be pulled out, and then the sandpaper is replaced and then directly inserted into the grinding mechanism, so the replacement is very convenient.

[0004] However, the above utility model still has some shortcomings:

[0005] During the use of the utility model, the wire core needs to pass through the middle of the four grinding seats, and the grinding sandpaper is pressed against the surface of the wire core under the action of the spring, and then the wire core is wound up by the winding wheel, and the winding movement of the wire core and the grinding sandpaper generate friction to grind the surface of the wire core. During each grinding, only one wire core can pass between the four grinding seats, which results in limited grinding efficiency of the wire core.

This is to grind the surface of the wire core along the axial direction of the wire core. This results in the wire core surface in the gap between every two adjacent grinding seats being unable to be effectively grinded, thereby reducing the grinding effect of the wire core surface.

[0034] Specifically, the side close to the axis of the grinding cylinder 81 is the inner side, and the side away from the axis of the grinding cylinder 81 is the outer side;

[0035] The setting of the universal wheel 2 facilitates the movement and transportation of the entire device; the wire core 13 passes through the limiting hole 12 on the right side mounting block 6, then passes between the inner grinding component 7 and the outer grinding component 8, and finally passes through the limiting hole 12 on the left side mounting block 6, and the oxide on the surface of the wire core 13 is polished by the inner grinding component 7 and the outer grinding component 8;

[0036] The driving assembly 9 is used to control the relative rotation of the inner grinding assembly 7 and the outer grinding assembly 8, and utilizes the friction force of the inner grinding assembly 7 and the outer grinding assembly 8 on the surface of the wire core 13 to make the wire core 13 rotate inside the inner grinding assembly 7 and the outer grinding assembly 8. At the same time, the wire core 13 is gradually pulled out from the inner grinding assembly 7 and the outer grinding assembly 8, so as to achieve the grinding of the surface of the wire core 13 along the axial direction of the grinding cylinder 81 and along the radial direction of the grinding cylinder 81, thereby improving the grinding effect of the wire core 13.

[0037] In addition, a plurality of limiting holes 12 are provided on the mounting block 6, which can ensure that a corresponding number of wire cores 13 pass through between the inner grinding component 7 and the outer grinding component 8, so that a plurality of wire cores 13 can be ground simultaneously, thereby improving the grinding efficiency.

[0038] Furthermore, the inner grinding component 7 includes a grinding column 71 , both ends of which are rotatably mounted on the mounting block 6 via connecting columns 72 , and a grinding sandpaper 73 is bonded to the side wall of the grinding column 71 .

[0039] Specifically, one end of the connecting column 72 is fixedly connected to the end surface of the polishing column 71, and the other end thereof is rotatably mounted on the mounting block 6; the polishing sandpaper 1 73 is bonded to the outer wall of the polishing column 71 by double-sided adhesive, and when the polishing column 71 rotates, the polishing sandpaper 1 73 is synchronously driven to rotate to polish the wire core 13;

[0040] The sliding base 3 drives the fixed plate 10, the placement base 11 and the grinding cylinder 81 to move horizontally on the main base 1, that is, the grinding cylinder 81 can move horizontally on the outside of the grinding column 71, which is convenient for the operator to replace the grinding sandpaper 73 adhered to the outer wall of the grinding column 71.

[0041] Furthermore, the external grinding assembly 8 includes a plurality of arc blocks 82, which are evenly distributed in the grinding cylinder 81. The grinding cylinder 81 is rotatably connected to the placement base 11. A threaded rod 87 is rotatably connected to the outer wall of the arc block 82. The threaded rod 87 is screwed to the side wall of the grinding cylinder 81. A limiting rod 88 is fixedly connected to the outer wall of the arc block 82. The limiting rod 88 penetrates the side wall of the grinding cylinder 81. The limiting rod 88 is arranged along the axial direction of the grinding cylinder 81 and parallel to the threaded rod 87.

[0042] Specifically, the axis direction of the threaded rod 87 and the axis direction of the grinding cylinder 81 are perpendicular to each other; the rotation of the threaded rod 87 can drive the arc block 82 to move along the radial direction of the grinding cylinder 81, so that the wire cores 13 of different diameters pass through the grinding sandpaper 1 73 and the grinding sandpaper 2 86; the setting of the limit rod 88 is used to limit the rotation of the arc block 82;

[0043] In addition, the threaded rod 87 is used to adjust the distance between the axis line of the arc block 82 and the grinding cylinder 81. Compared with the elastic member, it can prevent the wire core 13 from being stuck in the gap between two adjacent arc blocks 82 when the grinding cylinder 81 and the grinding column 71 rotate relative to each other, thereby affecting the grinding efficiency and even damaging the wire core 13.

[0044] Furthermore, each arc block 82 has a T-shaped arc groove 83 on its inner side wall, a T-shaped arc block 84 is slidably installed in the T-shaped arc groove 83 , an arc plate 85 is fixedly connected to the T-shaped arc block 84 , and a grinding sandpaper 86 is bonded to the arc surface of the arc plate 85 .

[0045] Specifically, the second sandpaper 86 is adhered to the arc surface of the arc plate 85 by double-sided tape, and the T-shaped arc block 84 is slidably inserted into the T-shaped arc groove 83, so that the arc plate 85 can be removed and the second sandpaper 86 can be replaced.

[0046] Furthermore, the driving assembly 9 includes a motor 91, which is installed on the sliding base 3. The output shaft end of the motor 91 is connected to a thin rod 92, which passes through the fixed plate 10, and the key shaft on the outer wall of the thin rod 92 is connected to a thick rod 93, which is rotatably installed on the mounting plate 5 on the right.

[0047] Furthermore, gears 94 are sleeved and mounted on the outer side walls of the thin rod 92 and the grinding cylinder 81 , and the two gears 94 are meshed with each other.

[0048] Furthermore, rotating wheels 95 are sleeved and installed on the outer side walls of the thick rod 93 and the right connecting column 72 , and the two rotating wheels 95 are both transmission-connected to the belt 96 .

[0049] Specifically, when the motor 91 controls the thin rod 92 and the corresponding gear 94 to rotate, the other gear 94 will drive the grinding cylinder 81 to rotate in the opposite direction; at the same time, the thin rod 92 drives the thick rod 93 and the corresponding rotating wheel 95 to rotate in the same direction through the key slot, and drives the other rotating wheel 95 and the connecting column 72 and the grinding column 71 to rotate in the same direction through the transmission of the belt 96, thereby realizing the synchronous reverse rotation between the grinding column 71 and the grinding cylinder 81 to grind the wire core 13.

[0050] Working principle and use process of the utility model: After the utility model is installed, the wire core 13 passes through the limiting hole 12 on the right side of the mounting block 6, then passes between the inner grinding component 7 and the outer grinding component 8, and finally passes through the limiting hole 12 on the left side of the mounting block 6, and each limiting hole 12 is provided with a wire core 13;

[0051] The motor 91 controls the thin rod 92 and the corresponding gear 94 to rotate, and the other gear 94 drives the grinding cylinder 81 to rotate in the opposite direction. At the same time, the thin rod 92 drives the thick rod 93 and the corresponding rotating wheel 95 to rotate in the same direction through the key slot, and drives the other rotating wheel 95 and the connecting column 72 and the grinding column 71 to rotate in the same direction through the transmission of the belt 96, so as to realize the synchronous reverse rotation between the grinding column 71 and the grinding cylinder 81.

[0052] The grinding column 71 drives the grinding sandpaper 1 73 to rotate, and the grinding cylinder 81 drives the grinding sandpaper 2 86 to rotate, and the friction between the grinding sandpaper and the wire core 13 is used to make the wire core 13 rotate between the grinding sandpapers. At the same time, the wire core 13 is gradually pulled out from between the grinding sandpapers, so that the surface of the wire core 13 is ground along the axial direction of the grinding cylinder 81 and along the radial direction of the grinding cylinder 81, thereby improving the grinding effect of the wire core 13.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
