Description

Technical Field

[0001] This invention relates to the field of insulator processing technology, and in particular to an insulator skirt trimming and trimming equipment and method. Background Technology

[0002] After composite insulators are vulcanized in a mold, flash will form on the outer edge of their silicone rubber sheds along the mold parting line. Currently, the removal of flash mainly relies on manual scraping with knives, or grinding and trimming with grinding wheels, wire wheels, or other polishing equipment.

[0003] Manual scraping is inefficient, involves uneven force, and makes it difficult to maintain a consistent scraping amount. It easily leaves cuts of varying depths on the edge of the skirt, and prolonged operation can lead to fatigue. When grinding is applied to highly elastic silicone rubber, the edge of the skirt deforms under grinding pressure, which can easily result in burrs, frayed edges, and localized overheating, damaging the surface quality of the skirt. In addition, the boundary between the burr and the skirt body is difficult to identify precisely visually, and during operation, it is easy to incompletely remove the burr or over-cut and damage the skirt body. The removed burr chips adhere to the tool and the skirt surface, making cleaning time-consuming.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an insulator skirt trimming equipment and its processing method. Summary of the Invention

The upper cabinet doors are connected to the upper cabinet via hinges, and a controller is fixedly installed on the side wall of the upper cabinet.

[0015] A processing method for trimming the burrs on insulator skirts includes the following steps: S1. The insulator body is sleeved on the outside of the bearing column. The seventh motor is started. The seventh motor drives the rotating column and the arc block to rotate through the third rotating rod. The sliding column slides along the arc groove and the slide rail through groove, driving the slider and the second card plate to move along the slide groove, so that the second card plate extends out from the side opening and internally supports and fixes the insulator body. S2. Start the rotary control motor, which drives the support plate and bearing column to rotate through the first base frame, thereby driving the insulator body to rotate; start the linear motor, which drives the trimming sleeve to rise and fall through the lead screw; start the fourth motor, which drives the connecting plate and the line laser contour sensor to rotate close to the insulator body through the first rotating rod, and scans the insulator body and its flash to obtain the contour and three-dimensional graphics. S3. Start the first motor, and through the meshing of the second gear with the first gear, drive the bushing, connecting pipe and nozzle to rotate out of the first side mounting cavity, so that the nozzle is located above the edge of the insulator body skirt; open the control valve, and the liquid nitrogen in the liquid nitrogen storage tank is sprayed through the output pipe, input hose, connecting pipe and nozzle to the edge for deep cooling. S4. Start the sixth motor, which drives the L-shaped bracket and the roller to rotate out of the fourth side mounting cavity through the second rotating rod, the second connecting block and the side fixing rod; start the fifth motor to drive the roller to rotate, so that the roller rotates in the opposite direction to the insulator body, and cuts off the flash; when the roller retracts, the scraper ring slides along the roller through the third electric push rod and the first clamping plate to scrape off the attached flash. S5. Start the third motor, which drives the first electric push rod, U-shaped frame, and cylindrical roller to rotate out of the second side mounting cavity through the first transmission shaft and the first connecting block; start the first electric push rod to make the annular cutter and cylindrical roller fit against the edge of the insulator body skirt; start the second motor to make the cylindrical roller rotate in the opposite direction to the insulator body, and the annular cutter cuts off the remaining burrs on the edge of the skirt; after the trimming is completed, let the U-shaped frame enter the second side mounting cavity, release the positioning of the top plate by the second electric push rod, and rotate the output shaft of the second motor counterclockwise to drive the top plate and the chip pusher plate to rotate to scrape off the residual burrs; S6. Start the vacuum cleaner and suck up the burrs and debris through the suction pipe and dust cover.

[0016] The above technical solution has the following beneficial effects: 1. This invention uses a laser contour sensor in the scanning component to scan the insulator body and its flash and obtain the contour and three-dimensional graphics. It can accurately locate the flash position and boundary, providing an alignment basis for deep cooling, rolling and trimming operations, which helps to avoid damage to the umbrella skirt body due to incomplete flash removal or excessive cutting.

[0017] 2. This invention uses a cryogenic component to spray liquid nitrogen onto the flash to make it cryogenically embrittled, and then the roller cutter in the roller cutting component cuts and tears the embrittled flash from the root. This can avoid the stretching deformation and pulling that occurs when directly cutting the high elasticity silicone rubber flash, which helps to ensure the edge of the umbrella skirt is neat and avoids damage to the umbrella skirt body.

[0018] 3. The present invention, through the cooperation of the scraping ring and the first clamping plate in the rolling cutter assembly, scrapes off the burrs attached to the outside of the rolling cutter when the rolling cutter is retracted. This can prevent the burrs from adhering to the surface of the rolling cutter and affecting the continuous cutting, which is conducive to maintaining the cutting effect and the cleanliness of the cutting tool. The annular cutter in the trimming assembly cuts off the small burrs remaining after rolling cut, and scrapes off the residual burrs with the help of the chip pusher plate. This can finely trim the edge of the umbrella skirt, which is conducive to ensuring the integrity of the trimming and the uniformity of the edge of the umbrella skirt.

[0019] 4. The present invention uses a vacuum cleaner in the suction component to instantly remove burrs and debris through the suction pipe and the burr cover, which can avoid debris accumulation, entanglement and secondary pollution, and help maintain a clean processing environment and ensure continuous and stable processing.

[0020] 5. The present invention uses the second clamping plate in the bearing component to extend from the side opening to internally support and fix the insulator body, and uses a rotation control motor to drive its rotation, which can achieve stable clamping and constant speed rotation. Moreover, the internal support method does not clamp the outer edge of the umbrella skirt, which is beneficial to protect the surface of the umbrella skirt. Attached Figure Description

[0027] The working principle is as follows: The first motor 208 is started, and its output shaft drives the second gear 213 to rotate.

The embrittled burr is cut off from the root, avoiding damage to the edge of the umbrella skirt caused by directly tearing off the entire burr from the root when it is too large. When the roller cutter 711 completes the cutting and retracts into the fourth side mounting cavity 701, one end of the scraper ring 716 is inserted into the slot 713 of the first clamping plate 712. The third electric push rod 704 is started to drive the first clamping plate 712 to move, so that the scraper ring 716 slides along the outside of the roller cutter 711 to scrape off the burr debris attached to the surface of the roller cutter 711 and keep the roller cutter 711 clean.

[0037] The working principle is as follows: When the vacuum cleaner 4 is started, the vacuum cleaner 4 forms a negative pressure in the trimming area through the suction pipe 401 and the dust collection hood 403, which sucks in and collects the burrs generated by shearing, tearing and splitting; the inner side of the dust collection hood 403 is connected to the fixing ring 406 through multiple support rods 404, and the inner side of the fixing ring 406 is rotatably connected to the support plate 405, which supports the bearing column 8 and the insulator body 807; the rotary control motor 409 is started, and the output shaft of the rotary control motor 409 drives the support plate 405 to rotate relative to the fixing ring 406 through the first base frame 407, thereby driving the bearing column 8 and the insulator body 807 to rotate; the conductive slip ring 410 supplies power to the rotating components such as the seventh motor 812 that rotate with the support plate 405.

The insulator body (807) is sleeved on the outside of the bearing column (8), and the seventh motor (812) is started. The seventh motor (812) drives the rotating column (808) and the arc block (809) to rotate through the third rotating rod (803). The sliding column (811) slides along the arc groove (810) and the slide rail through groove (802), driving the slider (805) and the second clamping plate (806) to move along the slide groove (801), so that the second clamping plate (806) extends out from the side opening (804) and internally supports and fixes the insulator body (807). S2. Start the rotary control motor (409), which drives the support plate (405) and the bearing column (8) to rotate through the first base frame (407), thereby driving the insulator body (807) to rotate; start the linear motor (305), which drives the trimming sleeve (3) to rise and fall through the lead screw (303); start the fourth motor (603), which drives the connecting plate (604) and the line laser contour sensor (605) to rotate close to the insulator body (807) through the first rotating rod (606), and scans the insulator body (807) and its flash to obtain the contour and three-dimensional graphics; S3. Start the first motor (208), which meshes with the first gear (211) through the second gear (213), driving the bushing (210), connecting pipe (206) and nozzle (209) to rotate out of the first side mounting cavity (205), so that the nozzle (209) is located above the edge of the shed of the insulator body (807); open the control valve (202), and the liquid nitrogen in the liquid nitrogen storage tank (2) is sprayed through the output pipe (201), input hose (203), connecting pipe (206) and nozzle (209) to the edge for deep cooling; S4. Start the sixth motor (718), and drive the L-shaped bracket (709) and the roller (711) to rotate out of the fourth side mounting cavity (701) through the second rotating rod (705), the second connecting block (706) and the side fixing rod (708); start the fifth motor (710) to drive the roller (711) to rotate, so that the roller (711) and the insulator body (807) rotate in opposite directions, and cut off the flash; when the roller (711) is retracted, the scraper ring (716) is driven to slide along the roller (711) through the third electric push rod (704) and the first clamping plate (712) to scrape off the attached flash; S5. Start the third motor (511), which drives the first electric push rod (506), U-shaped frame (507) and cylindrical roller (510) out of the second side mounting cavity (501) through the first transmission shaft (503) and the first connecting block (504); start the first electric push rod (506) to make the annular cutter (509) and cylindrical roller (510) fit against the edge of the umbrella skirt of the insulator body (807); start the second motor (508) to make the cylindrical roller (510) and the insulator body (807) rotate in opposite directions, and the annular cutter (509) cuts the remaining burrs on the edge of the umbrella skirt; after the trimming is completed, make the U-shaped frame (507) enter the second side mounting cavity (501), the second electric push rod (514) releases the positioning of the top plate (512), and the output shaft of the second motor (508) rotates counterclockwise to drive the top plate (512) and the chip pusher plate (513) to rotate to scrape off the remaining burrs; S6. Start the vacuum cleaner (4) and suck up the burrs through the suction pipe (401) and the dust collection cover (403).
