Description

Technical Field

[0002] Silicon steel sheet core is an iron-silicon alloy formed by adding a small amount of silicon to pure iron. This type of core has the highest saturation magnetic induction value of 20000Gs; due to their good magnetic and electrical properties, easy mass production, low price, and small mechanical stress, they are widely used in the power electronics industry, such as power transformers, distribution transformers, current transformers and other cores. Silicon steel sheets have good toughness and can be punched, cut and processed. They can be made into laminated or wound ring cores. In actual use, the outer surface of the silicon steel sheet core needs to be polished to reduce wear and tear during use to improve performance. However, during the long-term polishing process, the polishing material will wear and fail to fully contact the workpiece. Therefore, a compensation mechanism is required to move the polishing material when the polishing material is worn to ensure contact with the workpiece.

Compared with the current electromagnet processing polishing device, the present invention is provided with a compensation mechanism.

On the other hand, the compensation mechanism can make the cooling plate arranged inside the transmission chamber.

DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Embodiment 1: A compensation mechanism for a polishing device for electromagnet machining, such as Figure 1-Figure 11As shown, it includes a support table 1, a workpiece 2 and a polishing table 10, wherein a polishing wheel 11 is rotatably connected to the top of the polishing table 10, a U-shaped tube 20 and a sliding rheostat 30 are fixedly connected inside the polishing table 10, a push rod 21 is slidably connected to one end of the U-shaped tube 20, an arc-shaped nozzle 22 is fixedly connected to one end of the push rod 21, a jet pump 55 is fixedly connected to one side of the arc-shaped nozzle 22 through a pipeline, an extrusion rod 18 is slidably connected to the other end of the U-shaped tube 20, a spring 19 is fixedly connected to the extrusion rod 18 and one end of the polishing table 10, a narrow groove 23 is fixedly connected to one side of the U-shaped tube 20, the U-shaped tube 20 and the narrow groove 23 are filled with non-conductive hydraulic oil, a strong magnet 24 is slidably connected to the narrow groove 23, and a narrow groove 23 is fixedly connected to the narrow groove 23. A magnet slide 25 is fixedly connected to the outside of the narrow groove 23, and a strong magnet 27 is slidably connected inside the magnet slide 25. The strong magnet 1 24 and the strong magnet 27 are attracted to each other. A rotating support rod 26 is fixedly connected to one side of the magnet slide 25, and an adjustment lever 28 is rotatably connected to one end of the rotating support rod 26. One end of the adjustment lever 28 is movably connected to the strong magnet 27, and the other end of the adjustment lever 28 is movably connected to a sliding paddle 29. One end of the sliding paddle 29 is slidably connected to the inside of the sliding rheostat 30. A polishing motor 13 is fixedly connected to one side of the polishing table 10, and a guide wheel 54 is rotatably connected to one side of the polishing table 10. The polishing wheel 11, the guide wheel 54 and the power output end of the polishing motor 13 are transmission-connected. When polishing is performed, the polishing wheel 11 rotates at the bottom to polish the workpiece 2 at the top. During polishing, the paint pump 55 starts to work and sprays gas from the upper end of the narrow arc-shaped nozzle 22. The reaction force when the gas is sprayed and contacts the polishing wheel 11 causes the arc-shaped nozzle 22 and the push rod 21 to move downward and squeeze the spring 19. Since the U-shaped tube is filled with hydraulic oil, when the radius of the polishing wheel 11 is reduced due to long-term polishing, the gap between the polishing wheel 11 and the arc-shaped nozzle 22 increases, and the reaction force caused by the gas jet is reduced. Therefore, the push rod 21 will move upward under the squeezing of the squeezing rod 18. At the same time, the strong magnet 24 will be pushed downward. The narrow groove 23 is narrower inside than other parts of the U-tube. Therefore, when the moving distance of the strong magnet 1 24 is greater than the upward moving distance of the push rod 21, when the strong magnet 1 24 moves downward, it will drive the strong magnet 2 27 on one side to move downward together. When the strong magnet 27 moves downward, it can drive the adjustment lever 28 to rotate. The adjustment lever 28 with different lengths of the power arm and the resistance arm can further amplify the stroke, and drive the sliding paddle 29 on the other side to move upward to change the resistance of the sliding rheostat 30. Therefore, when the diameter of the polishing wheel 11 becomes smaller due to wear, the output power of the sliding rheostat 30 can be increased, and the polishing wheel 11 can be controlled to move upward so that the polishing wheel 11 is close to the workpiece 2 for grinding.

[0025] In order to solve the problem of the longitudinal and lateral movement of the polishing wheel 11 during grinding; Figure 1-Figure 11As shown, a transverse slide rail 6 is fixedly connected above the support platform 1, an electric slider 7 is slidably connected above the transverse slide rail 6, an arc-shaped nozzle screw 8 is fixedly connected above the electric slider 7, one side of the arc-shaped nozzle screw 8 is transmission-connected with an electric nut 9, one end of the electric nut 9 is fixedly connected to the polishing table 10, and one end of the sliding rheostat 30 is electrically connected to the electric nut 9; During grinding, the electric slider 7 can drive the polishing wheel 11 to move horizontally to adjust its own position to grind different positions of the workpiece 2. The sliding rheostat 30 is electrically connected to the control circuit of the electric nut 9. When the output power of the sliding rheostat 30 increases, the electric nut 9 can be controlled to move upward to make the polishing wheel 11 close to the workpiece 2.

[0026] In order to solve the problem of clamping and fixing the workpiece 2 during processing; Figure 1-Figure 11 As shown, a clamping telescopic rod 3 is fixedly connected to the top of the support platform 1, a transmission rod 37 is fixedly connected to the movable end of the clamping telescopic rod 3, one end of the clamping rod 34 is rotatably connected to a rotating shaft 41, one end of the rotating shaft 41 is fixedly connected to a clamping plate 42, one end of the clamping plate 42 is fixedly connected to the workpiece 2, and one side of the workpiece 2 is movably connected to the polishing wheel 11; the clamping telescopic rod 3 is a double-headed telescopic rod, which can drive the clamping plates 42 on both sides to move inward when contracted to clamp both sides of the workpiece 2; One side of the clamping rod 34 is fixedly connected to a rotating motor 35, one side of the clamping telescopic rod 3 is rotatably connected to a transmission tube 36, one side of the transmission tube 36 is slidably connected to a transmission rod 37, one end of the transmission rod 37 is fixedly connected to a transmission gear 38, one end of the transmission gear 38 is fixedly connected to a transmission wheel 1 39, the other end of the transmission gear 38 is transmission-connected to the power output end of the rotating motor 35, one end of the transmission gear 38 is transmission-connected to a transmission wheel 2 40, one end of the transmission wheel 2 40 is fixedly connected to a rotating shaft 41, and the other end of the transmission wheel 2 40 is rotationally connected to the clamping rod 34; After the clamping is completed, the rotating motor 35 works and can simultaneously drive the rotating shafts 41 on both sides to rotate through the transmission tube 36 and the transmission rod 37, so that the workpiece 2 can rotate itself while the polishing wheel 11 is grinding, making the polishing effect more uniform.

[0027] In order to solve the problem of a lot of dust during polishing; Figure 1-Figure 11 As shown, a dust box 12 is fixedly connected to one side of the polishing table 10, a scraper 14 is fixedly connected to one side of the dust box 12, one side of the scraper 14 is movably connected to the polishing wheel 11, a dust suction head 15 is fixedly connected to one side of the dust box 12, one side of the dust suction head 15 is fixedly connected to an air pump 4 through a pipeline, and an air pump 55 is fixedly connected above the air pump 4; The scraper 14 can scrape off large debris, the dust box 12 can be used to collect dust generated during grinding, and the vacuum pump 4 can suck dust from one side to prevent dust from spreading.

[0028] In order to solve the problem that high-speed rotation during polishing causes excessive temperature and affects the polishing effect; Figure 1-Figure 11 As shown, one side of the polishing table 10 is fixedly connected to a water spray bracket 31, one side of the water spray bracket 31 is rotatably connected to a rotating bracket 17, the other side of the water spray bracket 31 is fixedly connected to a water spray pipe 16, one side of the rotating bracket 17 is rotatably connected to an extrusion wheel 32, one side of the water spray pipe 16 is fixedly connected to a nozzle 33 and the other side is fixedly connected to a water tank 5, one side of the polishing wheel 11 is transmission-connected to the rotating bracket 17, when the rotating bracket 17 rotates with the polishing wheel, the extrusion wheel 32 on one side will squeeze the water spray pipe 16 in turn, squeeze out the internal liquid and spray it on the contact point between the polishing wheel 11 and the workpiece 2, which can control the water spraying amount while cooling and reducing dust.

[0029] When the present embodiment is in use, the electric slider 7 can drive the polishing wheel 11 to move laterally to adjust its position to polish different positions of the workpiece 2 during polishing; During polishing, the polishing wheel 11 rotates downward to polish the workpiece 2 above. During polishing, the paint pump 55 starts to work and sprays gas from the upper end of the narrow arc-shaped nozzle 22. The reaction force when the gas is sprayed and contacts the polishing wheel 11 causes the arc-shaped nozzle 22 and the push rod 21 to move downward and squeeze the spring 19. Since the U-shaped tube is filled with hydraulic oil, when the radius of the polishing wheel 11 is reduced due to long-term polishing, the gap between the polishing wheel 11 and the arc-shaped nozzle 22 increases, and the reaction force caused by the gas jet is reduced. Therefore, the push rod 21 will move upward under the squeezing of the squeezing rod 18. At the same time, the strong magnet 24 will be pushed downward. Since the narrow groove 23 is narrower than other parts of the U-tube, When the moving distance of the strong magnet 1 24 is greater than the upward moving distance of the push rod 21, the strong magnet 1 24 will drive the strong magnet 2 27 on one side to move downward together when it moves downward. When the strong magnet 27 moves downward, it can drive the adjustment lever 28 to rotate. The adjustment lever 28 with different lengths of the power arm and the resistance arm can further amplify the stroke, and drive the sliding paddle 29 on the other side to move upward to change the resistance of the sliding rheostat 30. Therefore, when the diameter of the polishing wheel 11 is reduced due to wear, the output power of the sliding rheostat 30 can be increased. The sliding rheostat 30 is electrically connected to the control circuit of the electric nut 9. When the output power of the sliding rheostat 30 increases, the electric nut 9 can be controlled to move upward to make the polishing wheel 11 close to the workpiece 2. The clamping telescopic rod 3 is a double-headed telescopic rod, which can drive the clamping plates 42 on both sides to move inward when contracted to clamp the two sides of the workpiece 2. After the clamping is completed, the rotating motor 35 works and can simultaneously drive the rotating shafts 41 on both sides to rotate through the transmission tube 36 and the transmission rod 37, so that the workpiece 2 can rotate itself when the polishing wheel 11 is polishing, so that the polishing effect is more uniform; When the rotating bracket 17 rotates with the polishing wheel, the extrusion wheel 32 on one side will squeeze the water spray pipe 16 in turn, squeeze out the internal liquid and spray it on the contact point between the polishing wheel 11 and the workpiece 2, which can cool down and reduce dust while controlling the amount of water spraying. The scraper 14 can scrape off large debris, the dust box 12 can be used to collect dust generated during grinding, and the vacuum pump 4 can suck dust from one side to prevent dust diffusion, which can effectively prevent overheating and dust diffusion.

[0030] Embodiment 2: A polishing device for electromagnet processing, such as Figure 1-Figure 11 As shown, in order to solve the problem that the middle silicon steel sheet will slide relative to each other after clamping the two sides when fixing the laminated annular core; this embodiment makes the following improvements on the basis of embodiment 1: one side of the rotating shaft 41 is slidably connected to an internal support plate 44, and a spring 2 45 is fixedly connected to the internal support plate 44 and one side of the rotating shaft 41, and one side of the internal support plate 44 is fixedly connected to an internal support rod 50, and a plurality of translation grooves 47 are opened around the internal support plate 44, and one end of the internal support rod 50 is slidably connected to a transverse sleeve 46, and one side of the transverse sleeve 46 is rotatably connected to a connecting rod 49, and one side of the connecting rod 49 is rotatably connected to an internal support plate 48, and one side of the internal support plate 48 is slidably connected to the translation groove 47, and a spring 3 53 is fixedly connected between the transverse sleeve 46 and the internal support rod 50; When the clamping telescopic rod 3 is retracted, the lateral sleeves 46 at both ends extend into the interior of the workpiece 2 and squeeze each other, so that the lateral sleeve 46 slides relative to the internal support rod 50. During the sliding, the inner support plate 48 is moved outward through the connecting rod 49 to support the interior of the workpiece 2 to prevent the silicon steel sheet located on the inner side from sliding downward. The second spring 45 can provide a buffer to prevent the inner support plate 48 from contacting the interior of the workpiece 2 and being unable to move when the clamping plate 42 has not yet contacted one side of the workpiece 2. One side of the lateral sleeve 46 is fixedly connected with a connecting boss 51, and the other side of the lateral sleeve 46 is provided with a connecting groove 52. When the lateral sleeves 46 on both sides are in contact, the connecting boss 51 is inserted into the connecting groove 52 to prevent the lateral sleeves 46 at both ends from rotating inconsistently.

[0031] In order to further prevent the problem of silicon steel sheet temperature rising during grinding; Figure 1-Figure 11 As shown, a cooling fin 43 is rotatably connected to one side of the clamping plate 42 , and the cooling fin 43 is preferably a semiconductor cooling fin. The cooling side faces the clamping plate 42 , and the temperature of the inner workpiece 2 can be reduced through the clamping plate 42 .

Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
