[0002] With the continuous development of science and technology, the power industry has also made rapid progress. Therefore, the application of lightning protection for electrical equipment has become more and more common, which has led to more applications for lightning arresters. Lightning arrester: an electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-up time, and often limit the follow-up amplitude. There are many types of lightning arresters, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, fully insulated composite jacket metal oxide arresters, and removable arresters. The main types of lightning arresters include tube-type lightning arresters, valve-type lightning arresters, and zinc oxide lightning arresters. The main working principles of each type of lightning arrester are different, but their working essence is the same, all of which are to protect communication cables and communication equipment from damage. With the increasing application of lightning arresters, metal rods need to be polished during the production and processing of lightning arresters, so a grinder is needed for polishing.

[0003] At present, when a metal rod grinder is grinding, the large contact area between the grinding teeth and the metal rod makes it difficult to discharge the grinding chips, causing the grinding chips to accumulate together. At the same time, the grinding area is prone to be filled with a large amount of dust and chips, which is inconvenient to reduce dust. This not only affects the air quality, but also causes the workers to inhale it into their bodies, affecting their health. Summary of the invention

At this time, the grinding chips are moved into the square tube under the guidance of the trapezoidal groove and finally fall into the dust collecting box. The grinding chips are collected and disposed of in time.

[0005] The reinforcing assembly includes a supporting plate, the outer surface of which is fixedly connected to the inner surface of the dust collecting box by screws, a U-shaped notch is provided at the bottom of the outer surface of the supporting plate, and a pressing protrusion is fixedly connected to the outer surface of the supporting plate and close to the U-shaped notch, and the dust collecting box is supported by the supporting plate, so that the dust collecting box itself has high strength, is less affected by external forces, and is not prone to skewing; At the same time, by staggered arrangement of the pressing protrusions and the U-shaped notches, the interaction between the pressing protrusions, the U-shaped notches and the auxiliary modules can be utilized to promote the collection of wear chips, and the interaction between the structures can be fully utilized to connect the structures together.

[0006] Preferably, a rectangular opening is provided at the center of the top of the dust collecting box, and the square tube passes through the rectangular opening. A strip extension edge is fixedly connected to the top of the inner surface of the dust collecting box and close to the rectangular opening. Two strip extension edges are provided, and the two strip extension edges are symmetrically arranged along the rectangular opening. The two symmetrical strip extension edges can be used to seal the rectangular opening to reduce the outflow of grinding chips and debris. The material of the strip extension edge is set to rubber material, which has good flexibility and is easy to deform, thereby facilitating the movement of the square tube. A slag discharge port is provided on the outer surface of the dust collecting box and close to one end of the Z-shaped pallet.

When the output end of the hydraulic rod pushes the square tube to move linearly, the auxiliary module as a whole also moves together. With the continuous movement, the ball is pushed by the pressing protrusion, so that the zigzag swing rod drives the percussion hammer to rotate counterclockwise, and the right-angle elastic strip is compressed. When the ball is separated from the pressing protrusion, the driving force disappears, and under the elastic force of the right-angle elastic strip, the zigzag swing rod drives the knocking hammer to rotate clockwise to reset. At this time, the top of the knocking hammer knocks on the inner wall of the square tube, and then under the action of vibration, the falling of the grinding chips can be accelerated, which promotes the collection of the grinding chips.

[0009] Preferably, one end of the right-angle elastic strip away from the zigzag swing rod is fixedly connected to the inner surface of the square tube, so as to compress the right-angle elastic strip when the zigzag swing rod is rotated to adjust the angle. The inner surface of the square tube is provided with a rotation groove which is compatible with the top of the zigzag swing rod, so as to facilitate the rotation of the zigzag swing rod to adjust the angle.

[0011] Preferably, the movable plate comprises a right-angle baffle, the top of the right-angle baffle is fixedly connected to the output end of the cylinder, the outer surface of the servo motor is fixedly connected to the outer surface of the right-angle baffle, the output end of the servo motor passes through the right-angle baffle, the edge of the outer surface of the right-angle baffle is fixedly connected to a filling strip, the outer surface of the filling strip is rollingly connected to a ball, and the output end of the servo motor is rotated so that the metal rod is driven to rotate quickly, thereby facilitating the grinding of the metal rod; At the same time, the extension and contraction of the output end of the cylinder is utilized to drive the movable plate as a whole to move upward and downward. At this time, the metal rod is driven to move up and down, and the height of the metal rod is adjusted.

[0012] When the filling strip is inserted into the Z-shaped pallet that is symmetrical on both sides, the interaction force between the structures can be used to make the right-angle baffle support the servo motor more stable and less likely to shake; At the same time, the right-angle baffle will block the slag discharge port, making it difficult for the grinding chips in the dust collecting box to float out.

[0013] Preferably, the balls are evenly distributed on the outer surface of the filling strip, and the balls can roll, using rolling friction to reduce frictional resistance, so that the right-angle baffle moves up and down smoothly. The outer surface of the filling strip is provided with rolling grooves adapted to the balls to facilitate the rolling of the balls.

[0014] Preferably, an anti-sway component is provided on the outer surface of the frame and on a side away from the clamping mechanism, and the anti-sway component includes a sliding plate, the outer surface of the sliding plate is slidably connected to the outer surface of the frame, and an electric telescopic rod is fixedly connected to the central position of the outer surface of the sliding plate, the output end of the electric telescopic rod passes through the sliding plate, and the output end of the electric telescopic rod is rotatably connected to a universal ball, and an end of the universal ball away from the electric telescopic rod is fixedly connected to a support cover, which can drive the electric telescopic rod to slide upward with the sliding plate, and make the support cover flush with the clamping chuck, and use the extension of the electric telescopic rod to push the support cover to the left side, at this time, the support cover covers the end of the metal rod away from the clamping chuck, and then supports the metal rod, so that the axis of the metal rod can rotate on the horizontal line, and the metal rod rotates smoothly, so that the metal rod is not easy to swing at will when it rotates quickly; At the same time, the support cover is conical, and its diameter gradually increases from right to left, which can adapt to metal rods of different diameters and has strong adaptability.

[0015] Preferably, the outer surface of the frame is provided with a sliding groove matched with the outer surface of the sliding plate, and the support cover is configured to be conical.

[0016] The present invention provides a metal rod grinding machine, which has the following beneficial effects: 1. The metal rod grinding machine uses two limit plates that are symmetrical along the square tube and have a V-shaped opening to limit the metal rod to be ground, and is not prone to offset. The square tube can be driven to move back and forth in a straight line through the extension and contraction of the output end of the hydraulic rod. At this time, the grinding teeth grind the metal rod steadily. At the same time, the outer surface of the grinding teeth is a plane, so that the grinding teeth and the metal rod are in line contact, which reduces the contact area, is not prone to accumulation of wear debris, and is not prone to scratches on the surface of the metal rod, thereby achieving a good grinding effect.

[0017] 2. In this metal rod grinding machine, when the grinding chips fall into the trapezoidal groove, the rapid rotation of the metal rod will generate a rotating airflow on the surface of the metal rod. At this time, the grinding chips are moved into the square tube under the guidance of the trapezoidal groove by the blowing of the airflow and finally fall into the dust collecting box, so that the grinding chips are collected in time and the grinding chips and debris are disposed of in time.

[0018] 3. The metal rod grinder supports the dust collecting box by supporting the flat plate, so that the dust collecting box itself has high strength, reduces the influence of external force, and is not easy to be skewed. At the same time, the pressing protrusions and the U-shaped notches are arranged alternately, and the interaction between the pressing protrusions, the U-shaped notches and the auxiliary modules can be utilized to promote the collection of grinding chips.

[0019] Fourth, the metal rod grinding machine, as it continues to move, causes the ball to be pushed by the pressing protrusion, and then the zigzag swing rod drives the knocking hammer to rotate counterclockwise. When the pushing force on the ball disappears, and under the elastic force of the right-angle elastic strip, the zigzag swing rod drives the knocking hammer to rotate clockwise to reset. At this time, the top end of the knocking hammer knocks the inner wall of the square tube, and then under the action of vibration, the falling of the grinding chips can be accelerated, which promotes the collection of the grinding chips.

[0020] 5. The metal rod grinding machine clamps one end of the metal rod by a clamping chuck, and rotates the output end of the servo motor so that the metal rod is driven to rotate rapidly, thereby facilitating the grinding of the metal rod. At the same time, the extension and contraction of the output end of the cylinder is utilized to drive the movable plate as a whole to move upward and downward. At this time, the metal rod is driven to move up and down, and the height of the metal rod is adjusted.

[0021] 6. The metal rod grinding machine uses a right-angle baffle to drive the filling bar to move downward. When the filling bar is inserted into the symmetrical Z-shaped clamping plates on both sides, the interaction force between the structures can make the right-angle baffle support the servo motor more stable and less likely to shake. At the same time, the right-angle baffle will block the slag discharge port, making it difficult for the grinding chips in the dust collecting box to float out.

[0022] 7. The metal rod grinding machine utilizes the extension of the electric telescopic rod to push the support cover to the left, thereby supporting the metal rod, so that the axis of the metal rod can rotate on the horizontal line, and the metal rod rotates smoothly, so that the metal rod is not easy to swing at will when it rotates quickly. At the same time, the support cover is conical, and the diameter gradually increases from right to left, which can adapt to metal rods of different diameters and has strong adaptability.

The square tube 33 passes through the rectangular opening 310. A strip extending edge 311 is fixedly connected to the top of the inner surface of the dust collecting box 31 and close to the rectangular opening 310. The material of the strip extending edge 311 is set to be rubber material, which has good flexibility and is easy to deform, thereby facilitating the movement of the square tube 33. A slag discharge port 312 is provided on the outer surface of the dust collecting box 31 and close to one end of the Z-shaped clamping plate 39. The limiting plate 34 is symmetrical along the square tube 33, and the limiting plate 34 is inclined to form a V-shaped opening, which can limit the metal rod to be polished and is not prone to deviation. The square tube 33 can be driven to move back and forth in a straight line by extending and contracting the output end of the hydraulic rod 32. At this time, the grinding teeth 35 can grind the metal rod steadily. At the same time, the outer surface of the grinding tooth 35 is set to be flat and inclined, so that the grinding tooth 35 and the metal rod are in line contact, which reduces the contact area and is not easy to cause accumulation of grinding chips; When the grinding teeth 35 are grinding the metal rod, the grinding chips generated by the grinding will fall into the trapezoidal groove 36, and the rapid rotation of the metal rod will cause a rotating airflow to be generated on the surface of the metal rod. At this time, the grinding chips are moved into the square tube 33 by the blowing of the airflow and under the guidance of the trapezoidal groove 36, and finally fall into the dust collecting box 31, so that the grinding chips are collected in time.

[0027] The reinforcing assembly 37 includes a supporting plate 371, the outer surface of which is fixedly connected to the inner surface of the dust collecting box 31 by screws, a U-shaped notch 372 is provided at the bottom of the outer surface of the supporting plate 371, and a pressing protrusion 373 is fixedly connected to the outer surface of the supporting plate 371 and close to the U-shaped notch 372. The two ends of the supporting plate 371 are fixed to the inner wall of the dust collecting box 31, thereby supporting the dust collecting box 31, so that the dust collecting box 31 itself has high strength; At the same time, by staggered arrangement of the pressing protrusions 373 and the U-shaped notches 372 , the interaction between the pressing protrusions 373 , the U-shaped notches 372 and the auxiliary modules 38 can be utilized to promote the collection of wear debris.

When the output end of the hydraulic rod 32 pushes the square tube 33 to move linearly, the entire auxiliary module 38 also moves together, and the ball 382 is in contact with the outer surface of the pressing protrusion 373, and as it continues to move, the ball 382 is pushed by the pressing protrusion 373, so that the zigzag swing rod 381 drives the percussion hammer 384 to rotate counterclockwise, and the right-angle elastic strip 383 is compressed; When the ball 382 is separated from the pressing protrusion 373, the ball 382 is at the position of the U-shaped notch 372, and the driving force disappears. Under the elastic force of the right-angle elastic strip 383, the zigzag swing rod 381 drives the knocking hammer 384 to rotate clockwise for reset. At this time, the top end of the knocking hammer 384 knocks on the inner wall of the square tube 33, and the falling of the grinding chips can be accelerated under the action of vibration.

[0030] One end of the right-angle elastic strip 383 away from the zigzag swing rod 381 is fixedly connected to the inner surface of the square tube 33, so that the right-angle elastic strip 383 can be compressed when the zigzag swing rod 381 is rotated to adjust the angle. The inner surface of the square tube 33 is provided with a rotation groove that is compatible with the top of the zigzag swing rod 381, so that the zigzag swing rod 381 can be rotated to adjust the angle.

[0031] The second embodiment, as Figure 1-Figure 9 As shown, based on the first embodiment: A clamping mechanism 5, which is used to adjust the height of the metal rod and clamp and fix it, and a connecting plate 6 installed and fixed on the outer surface of the clamping mechanism 5; The outer surface of the clamping mechanism 5 is mounted and fixed to the top position of the outer surface of the frame 1 through the connecting plate 6; The clamping mechanism 5 includes a cylinder 51, the outer surface of the cylinder 51 is fixedly connected to the top of the frame 1 through a connecting plate 6, the output end of the cylinder 51 is fixedly connected to a moving plate 52, the outer surface of the moving plate 52 is fixedly mounted with a servo motor 53, the output end of the servo motor 53 is fixedly connected to a clamping chuck 54, one end of the metal rod is clamped by the clamping chuck 54, and the output end of the servo motor 53 is rotated, so that the metal rod is driven to rotate quickly, thereby facilitating the grinding of the metal rod; At the same time, the extension and contraction of the output end of the cylinder 51 is utilized to drive the movable plate 52 to move upward and downward as a whole.

[0032] The movable plate 52 includes a right-angle baffle 521, the top of which is fixedly connected to the output end of the cylinder 51, the outer surface of the servo motor 53 is fixedly connected to the outer surface of the right-angle baffle 521, the output end of the servo motor 53 passes through the right-angle baffle 521, the outer surface edge of the right-angle baffle 521 is fixedly connected with a filling strip 522, and the outer surface of the filling strip 522 is rollingly connected with a ball 523. When the output end of the cylinder 51 is extended, the right-angle baffle 521 is pushed downward, and at this time, the right-angle baffle 521 drives the filling strip 522 to move downward together. When the filling strip 522 is inserted into the Z-shaped card plates 39 symmetrical on both sides, the interaction force between the structures can be used to make the right-angle baffle 521 support the servo motor 53 more stable and less prone to shaking; At the same time, the right-angle baffle 521 blocks the slag discharge port 312, so that the grinding chips in the dust collecting box 31 are not easy to float out.

[0033] The balls 523 are evenly distributed on the outer surface of the filling strip 522. The balls 523 can roll and use rolling friction to reduce friction resistance, so that the right-angle baffle 521 can move up and down smoothly. The outer surface of the filling strip 522 is provided with rolling grooves that are compatible with the balls 523 to facilitate the rolling of the balls 523.

[0034] The third embodiment, as Figure 8-Figure 10 As shown, based on the second embodiment: An anti-sway component 7 is provided on the outer surface of the frame 1 and on the side away from the clamping mechanism 5. The anti-sway component 7 includes a sliding plate 71. The outer surface of the sliding plate 71 is slidably connected to the outer surface of the frame 1. An electric telescopic rod 72 is fixedly connected to the central position of the outer surface of the sliding plate 71. The output end of the electric telescopic rod 72 passes through the sliding plate 71. The output end of the electric telescopic rod 72 is rotatably connected to a universal ball 73. The end of the universal ball 73 away from the electric telescopic rod 72 is fixedly connected to a support cover 74. The sliding plate 71 can drive the electric telescopic rod 72 to slide upward, and make the support cover 74 flush with the clamping chuck 54. The extension of the electric telescopic rod 72 is used to push the support cover 74 to the left. At this time, the support cover 74 covers the end of the metal rod away from the clamping chuck 54, thereby supporting the metal rod, so that the axis of the metal rod can rotate on the horizontal line, and the metal rod rotates smoothly.

[0035] The outer surface of the frame 1 is provided with a sliding groove matched with the outer surface of the sliding plate 71 to facilitate the sliding of the sliding plate 71, and the support cover 74 is set to be conical.

[0036] When in use, first clamp one end of the metal rod to be polished by the clamping chuck 54, then drive the electric telescopic rod 72 to slide upward by the sliding plate 71, and make the support cover 74 flush with the clamping chuck 54, and use the extension of the electric telescopic rod 72 to push the support cover 74 to the left, at this time, the support cover 74 covers the end of the metal rod away from the clamping chuck 54, thereby supporting the metal rod; At this time, the servo motor 53 is turned on to work, so that the output end of the servo motor 53 drives the clamping chuck 54 to rotate, so that the metal rod is driven to rotate quickly, and at the same time, the output end of the cylinder 51 is extended to drive the moving plate 52 to move downward as a whole. At this time, the metal rod is driven to move downward, the height of the metal rod is adjusted, and the surface of the metal rod is brought into contact with the surface of the grinding tooth 35; And by utilizing the extension of the output end of the cylinder 51, the right-angle baffle 521 is pushed downward, and at this time, the right-angle baffle 521 drives the filling bar 522 to move downward together. When the filling bar 522 is inserted into the Z-shaped clamping plate 39 symmetrical on both sides, the interaction force between the structures can be utilized to make the right-angle baffle 521 support the servo motor 53 more stable and less prone to shaking. At the same time, the right-angle baffle 521 will block the slag discharge port 312; At this time, the hydraulic rod 32 is turned on to work, and the output end of the hydraulic rod 32 is extended to drive the square tube 33 to move, so that the metal rod can be ground by the linear movement of the grinding teeth 35. At the same time, the outer surface of the grinding teeth 35 is set to be flat and inclined, so that the grinding teeth 35 and the metal rod are in line contact, which reduces the contact area and is not easy to cause accumulation of grinding chips; When the grinding teeth 35 grind the metal rod, the grinding debris generated by the grinding will fall into the trapezoidal groove 36, and the rapid rotation of the metal rod will generate a rotating airflow on the surface of the metal rod. At this time, the grinding debris will move into the square tube 33 under the guidance of the trapezoidal groove 36 by the blowing of the airflow, and finally fall into the dust collecting box 31, so that the grinding debris can be collected in time. The ball 382 is in contact with the outer surface of the pressing protrusion 373, and as it continues to move, the ball 382 is pushed by the pressing protrusion 373, so that the zigzag swing rod 381 drives the knocking hammer 384 to rotate counterclockwise, and the right-angle elastic strip 383 is compressed. When the ball 382 is separated from the pressing protrusion 373, the ball 382 is at the position of the U-shaped notch 372, and the pushing force disappears. Under the elastic force of the right-angle elastic strip 383, the zigzag swing rod 381 drives the knocking hammer 384 to rotate clockwise to reset. At this time, the top end of the knocking hammer 384 knocks the inner wall of the square tube 33, and the falling of the grinding chips can be accelerated under the action of vibration. When the grinding is completed, the output end of the cylinder 51 can be contracted to lift the movable plate 52 as a whole, and the metal rod can be removed, and the grinding debris in the dust collecting box 31 can be discharged at the slag discharge port 312.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
