Description

Technical Field

[0001] This invention belongs to the field of cylindrical grinding technology, specifically relating to a grinding device for intelligent processing of surge arresters. Background Technology

[0002] Zinc oxide resistors are important components of high-voltage surge arresters, and the flatness of the two end faces of the zinc oxide resistors directly determines the performance of impulse current carrying capacity. Therefore, before the zinc oxide resistors are put into assembly and use, the two end faces must be ground to ensure that the end faces are flat.

[0003] Patent publication number CN214869181U relates to a grinding device for surge arrester production. The technical solution includes a housing, a rotating shaft on one side of the housing, one end of the rotating shaft extending to the outside of the other side of the housing, and fixing blocks on both sides of the housing. The inner ends of both fixing blocks extend into the housing, and a surge arrester body is located inside the two fixing blocks. A grinding mechanism is located inside the housing. The beneficial effects of this patent are: during grinding, it is unnecessary to fix the surge arrester body using a flexible hose, thus preventing injury to workers from the grinding device, reducing the probability of injury, and lowering labor intensity. By rotating the plate, the grinding block can move left and right while rotating around the surge arrester body, which not only improves the grinding quality of the surge arrester body but also increases grinding efficiency and reduces labor intensity.

[0004] In existing technologies, when grinding the two end faces of resistors of the same specifications, the resistors need to be removed and re-clamped, making it difficult to restore their original positions. This results in inconsistent removal amounts on both sides when grinding the other end face a second time. Furthermore, misalignment of the resistor clamping also leads to inconsistent removal amounts on both end faces. Additionally, the dust generated during grinding can cause the displacement sensor to misjudge, causing the rotating mechanism to rotate prematurely and resulting in damage to the resistors. Moreover, during the grinding process, continuous large-volume air intake and dust extraction can easily cause debris to bounce and splash. Summary of the Invention

[0005] Various embodiments of the disclosed technology relate to a grinding device for the production of intelligent surge arresters that can ensure automatic centering of the resistor sheet, thereby avoiding uneven grinding thickness at both ends of the resistor sheet due to misalignment.

[0006] According to the disclosed embodiments, a grinding device for intelligent processing of surge arresters includes a grinding table, a rotating device rotatably mounted on the inner wall of the grinding table, a mounting plate fixedly mounted on the front side of the rotating device, a support frame fixedly mounted on the front side of the mounting plate, a clamping plate slidably mounted on the front side of the mounting plate, and a centering assembly. The centering assembly includes a gear, a centering frame, a centering frame, a centering spring, a resistor, and a rotating groove. The gear is rotatably mounted on the front side of the mounting plate, the centering frame is slidably mounted on the top of the mounting plate, the centering frame slidably passes through the right side of the centering frame, the centering spring is disposed between the centering frame and the centering frame, the resistor is disposed on the top of the support frame, and the rotating groove is formed on the circumferential surface of the rotating device. The centering spring is deformed and stores force under the tension of the centering frame, and the centering frame is compressed by the reaction force of the compression centering spring to compress the resistor, thereby ensuring that the resistor is centered inside the support frame.

[0007] In some implementations, the support frame and the clamping plate are both curved, with the support frame and clamping plate having curved sides. Curved surfaces allow for better fit of the resistor. Toothed blocks are provided on the rear sides of both the clamping plate and the centering frame. A guide rail is fixedly installed on the inner wall of the grinding table, and a sliding device is slidably installed on the front side of the guide rail. The operation of the rotating device drives the mounting plate to rotate, which in turn drives the support frame to rotate, and the rotation of the support frame drives the resistor to rotate, aligning the other end face of the resistor with the grinding machine.

[0008] In some implementations, the clamping plate meshes with the gear, the centering frame meshes with the gear, the inner wall of the rotating groove is set as an inclined surface, the counterclockwise rotation of the gear will drive the centering frame to move downward, the downward movement of the centering frame will drive the centering frame to move downward, and the downward movement of the centering frame will block the end face of the resistor sheet after grinding.

[0009] In some implementations, the centering frame is used to press the resistor sheet to ensure that the resistor sheet is centered, the clamping plate is used to fix the resistor sheet, the rotating device is used to rotate the resistor sheet to facilitate grinding the other end face of the resistor sheet, and the sliding device is started to drive the grinder to the right again, and the grinder moves to the right again to grind the other end face of the resistor sheet.

[0010] In some implementations, a protective component and a dust collection component are also included. The protective component is used to protect the resistive element, and the dust collection component is used to capture grinding dust. The protective component includes a shielding frame, a bumper, a probe, and a return spring. The shielding frame is fixedly installed on the inner wall of the grinding table, the bumper is fixedly installed on the bottom of the sliding device, the probe is slidably installed on the inner wall of the grinding table, and the return spring is disposed between the grinding table and the probe. If the rotating device rotates prematurely, the probe will be limited by the bumper when it moves downward. The probe cannot move further downward because it is limited by the bumper, and the inability of the probe to move further downward prevents the rotating device from rotating further.

[0011] In some implementations, the top of the probe rod is set as an arc surface. Setting the top of the probe rod as an arc surface can reduce the friction when the probe rod contacts the rotating device. The anti-collision rod is used to limit the probe rod. When the probe rod contacts the rotating groove, and the sliding device drives the grinder to move to the left to reset, the grinder will be blocked by the shielding frame.

[0012] In some implementations, the dust collection assembly includes a dust collection hole, a dust collection plate, a rack, a moving frame, a linkage groove, a linkage roller, and an elastic telescopic rod. The dust collection hole is located at the bottom of the inner wall of the grinding table. The dust collection plate is rotatably mounted on the inner wall of the dust collection hole. The rack is slidably mounted on the top of the inner wall of the grinding table. The moving frame is fixedly mounted on the top of the rack. The linkage groove is located at the bottom of the probe rod. The linkage roller is rotatably mounted on the inner wall of the linkage groove. The elastic telescopic rod is fixedly mounted on the right side of the inner wall of the grinding table. When the moving frame moves to the right, it will squeeze the dust collection plate to flip to a vertical position. Flipping the dust collection plate to a vertical position increases the air intake area of ​​the dust collection hole, thereby enhancing the dust collection effect during the intervals of grinding operations.

[0013] In some implementations, a spring is provided between the suction plate and the suction hole, which can drive the suction plate to reset. The top of the moving frame is set as an inclined surface, which can reduce the friction when the moving frame contacts the linkage roller. When the linkage roller contacts the moving frame, the rack squeezes the suction plate, which can make the suction plate vibrate. When the suction plate is stuck by dust and has difficulty resetting, the free end of the elastic telescopic rod can push the rack under its own elastic force.

[0014] This invention provides a grinding device for intelligent processing of surge arresters. It has the following beneficial effects: 1. In this invention, the centering frame is compressed by the reaction force of the compression centering spring to press the resistor sheet. By having two sets of centering frames automatically press against the resistor sheet, the resistor sheet can be automatically centered and positioned, thus avoiding uneven grinding thickness at both ends of the resistor sheet caused by misalignment. The rotation of the mounting plate drives the rotation of the support frame, which in turn drives the rotation of the resistor sheet, aligning the other end of the resistor sheet with the grinding machine. The resistor sheet can be flipped and ground on both ends with only one clamping, eliminating the need for secondary disassembly and avoiding the offset of the resistor sheet caused by re-clamping, thereby improving the grinding accuracy and further avoiding uneven grinding thickness at both ends of the resistor sheet. The downward movement of the centering frame will cause the centering frame to move downward, which will block the end face of the resistor sheet after grinding. After clamping the resistor sheet, the centering frame will automatically rise to avoid this. When unloading, the centering frame will return to its original position to block the end face after grinding, allowing the worker to only grasp the circumferential surface of the resistor sheet for unloading, reducing the risk of contamination of the end face of the resistor sheet caused by gloves touching it.

[0015] 2. In this invention, when the rotating equipment rotates prematurely due to a misjudgment by the displacement sensor, the probe rod will be unable to continue moving downwards, thus preventing the rotating equipment from continuing to rotate. This locks the rotating equipment, preventing the resistor sheet from colliding with the grinder, thereby reducing damage to the resistor sheet and the equipment from impact.

[0016] 3. In this invention, when the sliding device moves the grinder to the left to reset, the grinder will be blocked by the shielding frame. The shielding frame blocks the grinding head synchronously as the grinder resets, thereby preventing workers from accidentally touching the high-temperature grinding parts when picking up materials, thus avoiding burns and improving the safety of grinding operations.

[0017] 4. In this invention, the moving frame moves to the right and squeezes the dust suction plate to flip to a vertical position. Flipping the dust suction plate to a vertical position increases the air intake area of ​​the dust suction hole, thereby enhancing the dust suction effect during the intervals of the grinding operation. By increasing the air intake area of ​​the dust suction hole when flipping the resistor, the dust suction effect can be strengthened, and the rebound of dust and debris caused by continuous high-volume suction can be avoided.

[0018] 5. In this invention, the rack pushes the dust suction plate, which can cause the dust suction plate to vibrate. The vibration generated when the dust suction plate flips can automatically shake off the accumulated dust and remove it in time, thereby reducing the long-term accumulation of dust and clogging of the suction hole. Moreover, when the dust suction plate is stuck and difficult to reset due to dust, the free end of the elastic telescopic rod can help the dust suction plate to return to its tilted state, ensuring that the dust suction plate flips smoothly.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] Please see Figure 1 - Figure 6One embodiment of the present invention includes a grinding table 1, a rotating device 2 rotatably mounted on the inner wall of the grinding table 1, a mounting plate 3 fixedly mounted on the front side of the rotating device 2, a support frame 4 fixedly mounted on the front side of the mounting plate 3, and a clamping plate 5 slidably mounted on the front side of the mounting plate 3. It also includes a centering assembly; the centering assembly includes a gear 6, a centering frame 7, a centering frame 8, a centering spring 9, a resistance element 10, and a rotating groove 11. The gear 6 is rotatably mounted on the front side of the mounting plate 3, the centering frame 7 is slidably mounted on the top of the mounting plate 3, and the centering frame 8 slidably penetrates through it. On the right side of the centering frame 7, the centering spring 9 is set between the centering frame 7 and the centering frame 8. The resistance sheet 10 is set on the top of the support frame 4. The rotating groove 11 is opened on the circumference of the rotating device 2. By automatically pressing the resistance sheet 10 against the two sets of centering frames 8, the resistance sheet 10 can be squeezed and automatically centered, thereby avoiding uneven grinding thickness at both ends of the resistance sheet 10 due to misalignment. There are two sets of centering frames 8 and centering springs 9. The elastic coefficient of the centering spring 9 is much greater than the weight of the resistance sheet 10 itself, and the elastic coefficients of the two sets of centering springs 9 are the same.

[0023] The support frame 4 is curved on the side near the resistor 10, and the clamping plate 5 is also curved on the side near the resistor 10. By making the support frame 4 and the clamping plate 5 curved, the resistor 10 can be better fitted. The clamping plate 5 and the centering frame 7 are both provided with toothed blocks on their rear sides. The inner wall of the grinding table 1 is fixedly installed with a guide rail 121, and a sliding device 122 is slidably installed on the front side of the guide rail 121. The operation of the rotating device 2 drives the mounting plate 3 to rotate, the mounting plate 3 to rotate, and the support frame 4 to rotate, so that the other end face of the resistor 10 is aligned with the grinding machine. The resistor 10 can be flipped and the double end face grinding can be completed by clamping only once. There is no need for secondary disassembly and assembly, and the offset of the resistor 10 caused by re-clamping is avoided, thereby improving the grinding accuracy and further avoiding uneven grinding thickness at both ends of the resistor 10.

[0024] The clamping plate 5 meshes with the gear 6, the centering frame 7 meshes with the gear 6, and the inner wall of the rotating groove 11 is set as an inclined surface. The counterclockwise rotation of the gear 6 will drive the centering frame 7 to move downward. The downward movement of the centering frame 7 will drive the centering frame 8 to move downward. The downward movement of the centering frame 8 will block the end face of the resistor sheet 10 after grinding. When unloading, the centering frame 8 will reset to block the end face after grinding, so that the worker can only grasp the circumferential surface of the resistor sheet 10 for unloading, reducing the contamination of the end face of the resistor sheet 10 caused by hand touching the ground end face.

[0025] The centering frame 8 is used to press the resistor sheet 10 to ensure that the resistor sheet 10 is centered. The clamping plate 5 is used to fix the resistor sheet 10. The rotating device 2 is used to rotate the resistor sheet 10 to facilitate grinding the other end face of the resistor sheet 10. The sliding device 122 is started to drive the grinder to the right again. The grinder moves to the right again to grind the other end face of the resistor sheet 10.

[0026] In this embodiment, when the following is in operation: a linear motor is installed on the front side of the mounting plate 3 and the output end of the linear motor is fixedly connected to the clamping plate 5; a grinder is installed on the front side of the sliding device 122; a dust collection device is installed inside the grinding table 1; when the cylindrical resistor sheet 10 to be ground is placed on the top of the support frame 4, the resistor sheet 10 will contact the centering frame 8 and squeeze the centering frame 8; the centering frame 8 moves to the right under the pressure of the resistor sheet 10 and pulls the centering spring 9; the centering spring 9 deforms and stores force under the pull of the centering frame 8; and the centering frame 8 is squeezed by the reaction force of the centering spring 9 to squeeze the resistor sheet 10, thereby ensuring that the resistor sheet 10 is in the center position inside the support frame 4; after the resistor sheet 10 is centered, the linear motor is started to operate, and the linear motor operation drives the clamping plate 5 to move downward; When clamping plate 5 moves downward, it contacts and clamps resistor 10. Simultaneously, the downward movement of clamping plate 5 compresses gear 6, causing gear 6 to rotate clockwise. This clockwise rotation drives centering frame 7 to move upward, which in turn drives centering frame 8 to move upward. Centering frame 8 then disengages from resistor 10. Once centering frame 8 is out of contact with resistor 10, sliding device 122 is activated to move the grinder to the right. The grinder then contacts the left side of resistor 10 and grinds the end face of resistor 10. After grinding the left end face of resistor 10, sliding device 122 is activated to move the grinder to the left to reset. Once the grinder has reset, rotating device 2 rotates mounting plate 3, which in turn rotates support frame 4. Support frame 4 then rotates resistor 10, aligning the other end face of resistor 10 with the grinder. After the other end face of the resistor 10 is aligned with the grinder, the sliding device 122 is started to move the grinder to the right again. The grinder moves to the right again to grind the other end face of the resistor 10. Thus, the two end faces of the resistor 10 can be ground without removing the resistor 10. After the grinding of the two end faces of the resistor 10 is completed, the rotating device 2 drives the mounting plate 3 to rotate in the opposite direction to reset. The rotation of the mounting plate 3 drives the support frame 4 to rotate. The rotation of the support frame 4 drives the resistor 10 to rotate to reset. After the resistor 10 is rotated to reset, the linear motor drives the clamping plate 5 to move upward to disengage from the resistor 10. At the same time, the upward movement of the clamping plate 5 will squeeze the gear 6 to generate counterclockwise rotation. The counterclockwise rotation of the gear 6 will drive the centering frame 7 to move downward. The downward movement of the centering frame 7 will cause the centering frame 8 to move downward. The downward movement of the centering frame 8 will block the end face of the resistor 10 after grinding, so that the worker can only hold the circumferential surface of the resistor 10 for feeding, thus preventing the worker from touching the end face of the resistor 10 and causing contamination. After grinding, the worker needs to wear gloves to remove the resistor 10. The rotating device 2 is equipped with a signal receiving module, and the sliding device 122 is equipped with a displacement sensor. The displacement sensor is equipped with a signal transmitting module. After the sliding device 122 is reset, it will send a reset signal to the signal receiving module through the signal transmitting module. After receiving the reset signal, the signal receiving module will drive the rotating device 2 to rotate.

[0027] Please see Figure 1 - Figure 7 Based on the above embodiments, another embodiment of the present invention further includes a protective component and a dust collection component. The protective component is used to protect the resistor sheet 10, and the dust collection component is used to capture grinding dust. The protective component includes a shielding frame 123, a collision prevention rod 124, a detection rod 125, and a return spring 126. The shielding frame 123 is fixedly installed on the inner wall of the grinding table 1, the collision prevention rod 124 is fixedly installed on the bottom of the sliding device 122, the detection rod 125 is slidably installed on the inner wall of the grinding table 1, and the return spring 126 is disposed between the grinding table 1 and the detection rod 125. The detection rod 125 will be unable to move further downward, preventing the rotating device 2 from continuing to rotate, thereby locking the rotating device 2 and preventing the resistor sheet 10 from colliding with the grinding machine, thereby reducing the damage to the resistor sheet 10 and the equipment from collisions.

[0028] The top of the probe rod 125 is set as an arc surface. By setting the top of the probe rod 125 as an arc surface, the friction force when the probe rod 125 contacts the rotating device 2 can be reduced. The anti-collision rod 124 is used to limit the probe rod 125. When the probe rod 125 contacts the rotating groove 11, the sliding device 122 drives the grinder to move to the left to reset. The grinder will be blocked by the shielding frame 123. The shielding frame 123 blocks the grinding head synchronously with the grinder reset, thereby preventing workers from accidentally touching the high-temperature grinding parts when picking up materials, thus avoiding burns and improving the safety of grinding operations.

[0029] The dust collection assembly includes a dust collection hole 131, a dust collection plate 132, a rack 133, a moving frame 134, a linkage groove 135, a linkage roller 136, and an elastic telescopic rod 137. The dust collection hole 131 is located at the bottom of the inner wall of the grinding table 1. The dust collection plate 132 is rotatably mounted on the inner wall of the dust collection hole 131. The rack 133 is slidably mounted on the top of the inner wall of the grinding table 1. The moving frame 134 is fixedly mounted on the top of the rack 133. The linkage groove 135 is located at the bottom of the probe rod 125. The linkage roller 136 is rotatably mounted on the inner wall of the linkage groove 135. The elastic telescopic rod 137 is fixedly mounted on the right side of the inner wall of the grinding table 1. The dust collection effect is enhanced during the intervals of the grinding operation. By flipping the resistor 10, the air intake area of ​​the dust collection hole 131 is increased, which can enhance the dust collection effect and prevent dust and debris from rebounding due to continuous high-volume suction.

[0030] A spring is provided between the suction plate 132 and the suction hole 131. The spring can drive the suction plate 132 to reset. The top of the moving frame 134 is set as an incline. The incline of the top of the moving frame 134 can reduce the friction when the moving frame 134 contacts the linkage roller 136. When the linkage roller 136 contacts the moving frame 134, the rack 133 squeezes the suction plate 132, which can make the suction plate 132 vibrate. The vibration generated when the suction plate 132 flips can automatically shake off the accumulated dust and remove it in time, thereby reducing the long-term accumulation of dust and clogging of the suction hole 131. When the suction plate 132 is stuck and difficult to reset due to dust, the free end of the elastic telescopic rod 137 can push the rack 133 under its own elastic force. Moreover, when the suction plate 132 is stuck and difficult to reset due to dust, the free end of the elastic telescopic rod 137 can assist the suction plate 132 to restore the tilted state, ensuring that the suction plate 132 flips smoothly.

[0031] In this embodiment, during operation: the rotating device 2 rotates and squeezes the probe rod 125 through the rotating groove 11. The probe rod 125 moves downward under the pressure of the rotating device 2. The downward movement of the probe rod 125 squeezes the reset spring 126. The reset spring 126 deforms and stores force under the pressure of the probe rod 125. If the displacement sensor misjudges due to excessive dust, the rotating device 2 will rotate prematurely. At this time, the sliding device 122 will not return to the initial position to the left. The premature rotation of the rotating device 2 will cause the probe rod 125 to be limited by the anti-collision rod 124 when it moves downward. The probe rod 125 cannot continue to move downward due to the limitation of the anti-collision rod 124. The probe rod 125 cannot move further downward, so the rotating device 2 cannot continue to rotate. The rotating device 2 cannot continue to rotate, thus avoiding the collision between the resistor 10 or the centering frame 7 and the grinder. At the same time, when the sliding device 122 moves the grinder to the left to reset, the grinder will be blocked by the shielding frame 123, thus preventing workers from accidentally touching the grinder and getting burned when picking up materials.

[0032] The dust collection equipment is always on during the grinding operation. When the rotating equipment 2 rotates, the probe rod 125 moves downward, which will drive the linkage roller 136 to move downward. The linkage roller 136 moves downward and contacts the inclined surface of the moving frame 134 and squeezes the inclined surface of the moving frame 134. The moving frame 134 moves to the right due to the squeeze of the linkage roller 136. The movement of the moving frame 134 to the right will squeeze the dust collection plate 132 to flip to a vertical state. Flipping the suction plate 132 to a vertical position increases the air intake area of ​​the suction hole 131, enhancing the suction effect during the intervals of grinding operations. This prevents debris from rebounding and splashing due to continuous large-volume air intake. Simultaneously, the rack 133 pressing the suction plate 132 causes it to vibrate, allowing dust accumulated on the top of the suction plate 132 to be sucked into the suction device when the suction plate 132 is flipped. Furthermore, the rack 133 moving to the right compresses the free end of the elastic telescopic rod 137, causing it to retract. The retracted free end of the elastic telescopic rod 137 stores force, so that when the suction plate 132 is stuck and difficult to reset due to dust, the free end of the elastic telescopic rod 137 can push the rack 133 under its own elastic force, assisting the suction plate 132 in restoring its tilted state.

[0033] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
