Description

Technical Field

[0001] This invention relates to the field of precision machining technology for automotive parts, specifically to precision machining equipment and processing technology for automotive parts. Background Technology

[0002] Automotive parts processing can be divided into various methods, including stamping, milling, planing, grinding, fitting, and casting. Stamping uses a press and dies to apply external force to sheet metal, causing it to undergo plastic deformation or separation to obtain the desired shape. Milling mainly cuts materials such as copper, iron, aluminum alloy, stainless steel, and Teflon to form small and complex parts. Planing, grinding, and fitting are mainly used to perform finishing operations such as deburring and trimming on the outer layer of automotive parts after production.

[0003] For cylindrical parts in automobiles, such as brake lines, intake manifolds, exhaust pipes, fuel injectors, and piston inner walls, where a high degree of smoothness of the inner wall is required, the above-mentioned methods cannot be used for precision machining. In this case, an abrasive flow polisher is needed. The abrasive flow polisher continuously feeds abrasive materials that are not easily soluble in water into the corresponding parts through extrusion to complete the polishing process of parts with high requirements for the smoothness of the inner wall.

[0004] However, the abrasive flow grinders currently in use have the following main problems when precision machining automotive parts: 1. Abrasive residue will remain in the worktable, which is not only inconvenient to clean, but also inconvenient to continue grinding automotive parts. Moreover, in order to improve the utilization rate of abrasive, it will be reused many times, but the grinding effect will be reduced after repeated use.

[0005] 2. Traditional methods of polishing automotive parts require separating the parts for deburring. This necessitates manual removal of the parts, repositioning them, and waiting for them to be polished before moving on to the next part. This method of finishing cannot integrate a production line for deburring automotive parts, resulting in extremely low overall efficiency in removing burrs.

[0006] 3. Traditional abrasive grinding methods may result in some abrasive adhering to the inner surface of automotive parts. In such cases, operators need to collect the ground automotive parts and send them to a cleaning machine for cleaning. During the back-and-forth handling and cleaning process, the abrasive may condense on the inner surface of the automotive parts due to temperature changes, affecting the use of the automotive parts.

[0007] Therefore, the present invention provides a precision machining equipment and process for automotive parts to solve the problems existing in the precision machining of automotive parts. Summary of the Invention

At the same time, through the screening of the screening mechanism, the manual operation of removing automotive parts, adjusting the position of automotive parts, and removing automotive parts after polishing is no longer required. The production line for deburring automotive parts is integrated, which greatly improves the efficiency of removing burrs from automotive parts.

[0033] 3.

[0053] In this embodiment, any cylindrical automotive part that can be placed in the loading groove of the loading plate is acceptable. The automotive part selected in this embodiment is a fuel injector, but it is not limited to fuel injectors.

[0054] Please see Figure 1 A precision machining equipment for automotive parts includes a machine body 1, support rods 2 fixedly installed at the four corners of the machine body 1, protective plates 3 fixedly installed on the front and rear side walls of the machine body 1, and a grinding mechanism 4 provided on the upper surface of the machine body 1.

[0055] Please see Figure 2-6The grinding mechanism 4 includes a pressing part 40 that is slidably disposed between four support rods 2. A grinding part 41 is fixedly installed at the center of the pressing part 40, and the grinding part 41 passes through the pressing part 40 and moves up and down with the pressing part 40.

[0056] A moving mechanism 5 for continuously delivering fuel injectors 524 is fixedly installed between the pressing part 40 and the body 1.

[0057] Please see Figure 2 or Figure 7-11 The moving mechanism 5 includes a moving part 50 disposed at the front end of the body 1. The moving part 50 is provided with a limiting part 51 for moving the fuel injector 524. The upper surface of the limiting part 51 is provided with a loading part 52 for receiving the fuel injector 524.

[0058] A screening mechanism 6 is provided on the left side of the moving mechanism 5 to provide screening for the fuel injector 524.

[0059] Please see Figure 2 and Figure 12-15 The sieving mechanism 6 includes a rotating part 60 located on the left side of the machine body 1; a coaxial part 61 is provided inside the rotating part 60, and the coaxial part 61 cooperates with the loading part 52 to position the loading part 52 for easy loading of the fuel injector 524; a sieving part 62 is rotatably installed at the center of the rotating part 60, and a guide part 63 is fixedly installed on the upper surface of the sieving part 62, and the right end of the guide part 63 cooperates with the upper surface of the loading part 52 directly below it.

[0060] Please see Figure 12-15 The rotating part 60 includes a fixed housing 601, a rotating motor 602, a guide plate 603, a spool gear ring 604, and a sleeve 605. The fixed housing 601 is located on the left side of the machine body 1. The guide plate 603 is mounted inside the fixed housing 601 via bearings. The guide plate 603 has an I-shaped structure. The upper outer wall of the guide plate 603 is provided with a vortex-shaped protrusion, and the lower outer outer wall of the guide plate 603 is provided with a gear ring. The sleeve 605 is rotatably mounted outside the guide plate 603. The spool gear ring 604 is fixedly mounted on the outer wall of the sleeve 605. The rotating motor 602 is fixedly mounted inside the fixed housing 601 via a motor base. The output shaft of the rotating motor 602 is equipped with a bevel gear that meshes with the gear ring 604 and the gear ring on the outer wall of the guide plate 603.

[0061] See Figure 15The coaxial part 61 includes a reel 611, a top block cylinder 612, and a pressing cylinder 613. The top block cylinder 612 is fixedly installed inside the fixed housing 601 on the side opposite to the rotating motor 602. The output end of the top block cylinder 612 is rotatably mounted on the reel 611 via a support. The pressing cylinder 613 is fixedly installed on the upper end of the reel 611. The inner wall of the pressing cylinder 613 is provided with rubber protrusions to increase friction. The outer wall of the reel 611 and the outer wall of the reel gear ring 604 are rotatably connected to a rubber rope.

[0062] Please see Figure 2 , 12 and Figure 14 The sieving section 62 includes a fixed cylindrical ring 621, magnet blocks 622, a guide rotating cylinder 623, and a pulling strip 624. The fixed cylindrical ring 621 is located at the upper end of the fixed outer shell 601 directly above the rotating section 60, and the fixed cylindrical ring 621 is located outside the rotating section 60. The fixed cylindrical ring 621 is rotatably connected to the sleeve 605. A number of magnet blocks 622 are evenly arranged in a spiral manner along the circumferential direction on the inner wall of the fixed cylindrical ring 621. The upper end of the sleeve 605 is provided with a guide rotating cylinder 623 fitted inside the fixed cylindrical ring 621. The inner circumferential wall of the guide rotating cylinder 623 is evenly arranged with a pulling strip 624 that pushes the fuel injector 524 to move.

[0063] See Figure 12 and Figure 13 The flow guiding part 63 includes a flow guiding slide 631, a limiting block 632, and a stop bar 633. The flow guiding slide 631 is fixedly installed inside the fixed cylindrical ring 621 by a support frame, and the flow guiding slide 631 is attached to the tension strip 624 of the guide rotating cylinder 623. The limiting block 632 corresponding to the center position of the fuel injector 524 is fixedly installed inside the flow guiding slide 631. The stop bar 633 is rotatably connected to the outlet of the flow guiding slide 631 by a torsion spring, and the stop bar 633 is used in conjunction with the loading part 52.

[0064] In the specific operation, a certain amount of fuel injector 524 to be polished is first poured into the inside of the guide cylinder 623. Then, the rotating motor 602 is started. The rotating motor 602 drives the guide plate 603 and the sleeve 605 to rotate. At the same time, the rotating sleeve 605 drives the guide cylinder 623 to rotate. During the rotation, the vortex protrusion on the guide plate 603 provides friction to the fuel injector 524. The fuel injector 524 is pushed outward on the guide plate 603 according to the rotation of the vortex protrusion until the vortex protrusion of the guide plate 603 pushes the fuel injector 524 close to the inner wall of the guide cylinder 623. At this time, the magnet block 622 of the fixing ring 621 will just attract one fuel injector 524 to the inner wall of the guide cylinder 623.

[0065] After the fuel injector 524 is attracted, the pull bar 624 of the guide drum 623 will push the attracted fuel injector 524 to rotate. During this process, the fuel injector 524 will always be attracted to the guide drum 623 by the magnet 622. As the guide drum 623 rotates, the fuel injector 524 will move upward according to the spirally arranged magnet 622 until the pull bar 624 moves the attracted fuel injector 524 to the left end of the guide slide 631. At this time, the limiting block 632 in the guide slide 631 screens and adjusts the position of the incoming fuel injector 524. The limiting block 632 will contact the fuel injector 524 first. The narrow edge of the fuel injector 524 will slide in smoothly. If it comes into contact with the wide edge of the fuel injector 524, it will be squeezed out. Only when the wide edge of the fuel injector 524 is facing upward can it follow the pull bar 624 into the guide slide 631 and move upward in the guide slide 631 with the rotation of the guide cylinder 623. When the fuel injector 524 reaches the highest point of the guide slide 631, the attraction force of the magnet block 622 disappears. Then the fuel injector 524 will slide to the stop lever 633 with the guide slide 631. The stop lever 633 blocks the fuel injector 524 and concentrates the fuel injector 524 on the right side of the guide slide 631.

[0066] Please see Figure 7-9 The transfer unit 50 includes a double-sided slide rail 501, a conveyor belt 502, and an arc-shaped pusher block 503. The double-sided slide rail 501 is mounted on the top of the machine body 1 by a bracket. The beginning and end of the double-sided slide rail 501 are connected by a flip slide rail 53 on the right side. Limiting slide rails are provided on the inner walls of both the double-sided slide rail 501 and the flip slide rail 53. The conveyor belt 502 is fixedly installed on the lower side of the double-sided slide rail 501 away from the machine body 1. Arc-shaped pushers 503 are evenly distributed on the surface of the conveyor belt 502, and the arc-shaped pushers 503 are located at the center of the double-sided slide rail 501.

[0067] Please see Figure 9-10 The limiting part 51 includes a movable block plate 511, a cylindrical column 512, a bearing cylinder 513, and a movable small plate 514. The interior of the limiting slide is filled with several adjacent movable small plates 514, and several movable block plates 511 are equally spaced inside the limiting slide. The movable block plates 511 are mounted on the movable small plates 514. The bearing cylinder 513 is fixedly installed at the center of the movable block plate 511. The bearing cylinder 513 consists of an inner ring and an outer ring, and its inner ring can rotate relative to the outer ring. The inner side wall of the inner ring of the bearing cylinder 513 has a groove. The outer wall of the cylindrical column 512 is slidably connected to the interior of the bearing cylinder 513 by means of a protrusion. The lower end of the cylindrical column 512 cooperates with the arc-shaped push block 503.

[0068] Please see Figure 2 , 10-11, the loading section 52 includes a loading plate 521, a circular extrusion block 522, a loading groove 523 and an oil injector 524. The loading plate 521 is fixedly installed on the upper surface of the cylinder 512. Several loading grooves 523 are opened in the circumferential direction inside the loading plate 521, and the loading grooves 523 are provided through the loading plate 521. Several circular extrusion blocks 522 are fixedly installed on the upper surface of the loading plate 521 and above the loading grooves 523. The oil injector 524 is placed inside the loading groove 523.

[0069] In actual operation, when the fixed fuel injector 524 is moved to a new position, the conveyor belt 502 will rotate with the arc-shaped pusher 503. At the same time, when the arc-shaped pusher 503 contacts the cylinder 512, it will push the cylinder 512 to the left. At this time, the cylinder 512 will move to the left with the moving block 511 above it in the limiting slide.

[0070] The conveyor belt 502 will cooperate with the cylindrical column 512 through the arc-shaped pusher 503 to push the moving block 511 to move within the double slide rails 501. At the same time, it will cooperate with the moving small plate 514 that is closely attached to it, so that the moving small plate 514 is also pushed within the double slide rails 501. By squeezing and pushing the moving block 511 in front, the moving block 511 inside the entire limiting slide rail will complete the return motion.

[0071] When the moving block 511, carrying the loading plate 521, moves to the right side of the guide slide 631, it stops moving intermittently. Then, the top block cylinder 612 is activated, which pushes the spool 611 upward. At the same time, the spool 611 moves the extrusion cylinder 613 upward. When the extrusion cylinder 613 contacts the lower end of the cylinder 512, the extrusion cylinder 613 pushes the cylinder 512 upward. The cylinder 512 moves upward through the protrusion in the groove of the bearing cylinder 513 until it can no longer move upward. Then, the cylinder 512 is inserted into the extrusion cylinder 613.

[0072] Since the loading plate 521 is currently positioned below the stop lever 633, the spool 611 rotates along with the spool gear ring 604. Simultaneously, the spool 611 drives the cylinder 512 inside the extrusion cylinder 613 to rotate within the bearing cylinder 513 of the moving block plate 511. The cylinder 512 also drives the loading plate 521 to rotate. As the loading plate 521 rotates, the circular extrusion block 522 contacts the lower end of the stop lever 633, pushing the stop lever 633 aside and causing an oil injector 524 to fall out. The oil injector 524 will then... The nozzle 524 falls into the loading groove 523. At the same time, the stop lever 633 returns to its original position quickly under the action of the torsion spring. Then, the next circular extrusion block 522 on the same loading plate 521 will quickly replace it. Then, during the rotation, the stop lever 633 is triggered again, so that the next nozzle 524 falls directly into the current loading groove 523. The operation is repeated until the loading grooves 523 in the loading plate 521 are all filled with nozzles 524. Then, the top block cylinder 612 is activated in reverse, so that the cylinder 512 is disengaged from the extrusion cylinder 613.

[0073] Then the conveyor belt 502 is restarted to complete the filling work of the loading groove 523 in the next loading plate 521. The screening mechanism 6 and the moving mechanism 5 work together to solve the problem that the grinding of parts in the traditional way needs to be done separately. At the same time, through the screening of the screening mechanism 6, it is no longer necessary to manually take out the parts, adjust the position of the parts, and take out the parts after grinding, thus saving process steps.

[0074] Please see Figure 3-4 The pressing part 40 includes a cylinder 401, a hydraulic rod 402, a blowing frame 403, and a blower 404. The upper surfaces of the four support rods 2 are all fixedly mounted with inverted cylinders 401. The output end of the cylinder 401 is fixedly sleeved with a hydraulic rod 402. The lower surface of the hydraulic rod 402 is fixedly connected to the four corners of the upper surface of the blowing frame 403. The blowing frame 403 is arranged between the four support rods 2. The blower 404 is fixedly mounted on the upper surface of the blowing frame 403 and between two hydraulic rods 402.

[0075] Please see Figure 4-6 The grinding section 41 includes a storage cylinder 411, a feeding pipe 412, a circular pressing block 413, a baffle 414, a recovery bin 415, and a suction pipe 416. The storage cylinder 411 is fixedly installed at the center of the blowing frame 403. The feeding pipe 412 is threadedly connected to the upper surface of the storage cylinder 411. The circular pressing block 413 is fixedly sleeved at the lower end of the storage cylinder 411. The baffle 414 is slidably connected to the inside of the storage cylinder 411 through a telescopic hydraulic rod. The circular pressing block 413 is provided with circular holes that correspond one-to-one with the circular extrusion blocks 522 on the loading plate 521. The recovery bin 415 is fixedly installed at the lower end of the machine body 1 and below the blowing frame 403. The suction pipe 416 is fixedly connected to the center of the lower end of the recovery bin 415.

[0076] Please see Figure 6 The feeding unit 42 includes a feeding cylinder 421, a first water pump 422, a stirring motor 423, a paddle 424, and a second water pump 425. The feeding cylinder 421 is fixedly installed on the surface of the protective plate 3 on the front side of the machine body 1. The first water pump 422 is fixedly installed on the front surface of the feeding cylinder 421, and the extraction end of the first water pump 422 is fixedly connected to the front end of the suction pipe 416. The stirring motor 423 is fixedly installed at the center of the lower surface of the feeding cylinder 421. The output end of 423 is fixedly fitted with a rotating drum that penetrates the feeding cylinder 421, and the rotating drum has several holes and slots on the side near the bottom layer of the feeding cylinder 421. Several blades 424 are evenly distributed on the surface of the rotating drum connected to the stirring motor 423. A second water pump 425 is fixedly installed on the upper surface of the feeding cylinder 421, and the upper end of the second water pump 425 is fixedly connected to the front end of the feeding pipe 412. The extraction end of the second water pump 425 is rotatably connected to the rotating drum of the stirring motor 423.

[0077] When the loading plate 521 filled with fuel injectors 524 moves to the position directly below the circular pressure block 413, the conveyor belt 502 stops conveying, and the cylinder 401 is activated, causing the cylinder 401 to press down the blowing frame 403 with the four hydraulic rods 402 until the storage cylinder 411 with the circular pressure block 413 is just stuck on the loading plate 521 filled with fuel injectors 524. Then the cylinder 401 is closed, and the blower 404, the first water pump 422, the second water pump 425 and the stirring motor 423 are started at the same time. At this time, the second water pump 425 will draw the abrasive from the hole groove of the inner cylinder of the feeding cylinder 421 upward and discharge it into the storage cylinder 411 through the feeding pipe 412.

[0078] Simultaneously, when the abrasive fills the storage cylinder 411, the baffle 414 is opened by the squeezing action, allowing the abrasive to flow through the round hole at the top of the circular extrusion block 522 into the fuel injector 524 and then continue to flow into the recovery chamber 415. During the flow of the abrasive, the inner wall of the fuel injector 524 is polished and deburred. After the abrasive flows out from the loading groove 523, it will fall into the recovery chamber 415. The blower 404 will provide air pressure to the blowing frame 403, so that the fallen abrasive is fully blown into the recovery chamber 415 by the air pressure.

[0079] The abrasive material recycled inside the recycling bin 415 is drawn out by the first water pump 422 through the suction pipe 416 and discharged into the feeding cylinder 421. At this time, the stirring motor 423 stirs the new and old abrasive materials through the rotating drum and the blades 424. Then, the above operation is repeated to complete the grinding of the abrasive material on the nozzle 524. After the abrasive material has passed the nozzle 524 for a specified time, the cylinder 401 is started in reverse, and the material blowing frame 403 lifts the storage cylinder 411 to release the loading plate 521 with the nozzle 524 after grinding. The grinding is then carried by the conveyor belt 502. The fuel injector 524 continues to move, and after releasing the loading plate 521, the feeding of abrasive stops. The baffle 414 is reset by the telescopic hydraulic rod to complete the sealing of the abrasive inside the storage cylinder 411. The grinding mechanism 4 can blow down the abrasive that leaks onto the machine body 1 and the recovery bin 415, making it convenient for subsequent use. By recycling and mixing new and old abrasive, the problem of reduced abrasive grinding degree caused by repeated grinding is avoided. This can effectively improve the dimensional accuracy of automotive parts while reducing grinding costs, thereby increasing the wear resistance and service life of automotive parts.

[0080] Please see Figure 16 The cleaning mechanism 7 includes a water tank 701, a third water pump 702, an arc-shaped cleaning cylinder 703, and high-pressure nozzles 704. The water tank 701 is located on the right side of the machine body 1 and below the flip slide 53. The arc-shaped cleaning cylinder 703 is installed at the upper end of the water tank 701 and is located directly above the flip slide 53. Multiple high-pressure nozzles 704 are installed on the inner side of the arc-shaped cleaning cylinder 703. The third water pump 702 is installed at the upper end of the water tank 701 via a bracket. The water outlet of the third water pump 702 is connected to the multiple high-pressure nozzles 704, and the water inlet of the third water pump 702 is located inside the water tank 701.

[0081] When the loading plate 521 with the oil nozzle 524 moves on the flip slide 53 after grinding, water is sprayed out through the high-pressure nozzle 704 by the third water pump 702 to wash the abrasive adhering to the oil nozzle 524 and the abrasive on the loading plate 521, and to facilitate the oil nozzle 524 to be poured into the water tank 701.

[0082] After rinsing, the loading plate 521 continues to move to transport the next set of fuel injectors 524. The rinsing method can prevent abrasive from condensing on the inside of the fuel injectors 524, and at the same time, it can achieve the purpose of automatically collecting the deburred fuel injectors 524.

[0083] When specifically processing the burrs inside the fuel injector 524: S1: Sorting automotive parts: Pour a certain amount of fuel injector 524 into the sieving section 62, start the rotating motor 602, and after the rotating section 60 and the sieving section 62 work together, the fuel injector 524 is guided to the guide section 63. The sieving section 62 is used to limit the position of the fuel injector 524. After the fuel injector 524 is limited, the rotating section 60 will sort and transport the fuel injector 524 into the interior of the guide section 63 according to a certain placement position.

[0084] S2: Automotive parts collection and assembly: The start conveyor belt 502 moves the loading plate 521 along the double slide rails 501 to the right side of the guide slide rail 631 and stops moving. At this time, the top block cylinder 612 is started, and the coaxial part 61 is used to lift the loading plate 521 and rotate it. Through the cooperation of the loading part 52 and the guide part 63, the loading groove 523 in the loading plate 521 is filled with fuel injectors 524. After the fuel injectors 524 are filled, the top block cylinder 612 is started in reverse, so that the coaxial part 61 is disengaged from the loading part 52.

[0085] S3: Moving grouped automotive parts: Start the conveyor belt 502 to rotate the arc-shaped pusher 503, and push the loading part 52 forward through the arc-shaped pusher 503. Through the moving block plate 511 and the closely fitted moving small plate 514, the moving block plate 511 moves the upper loading plate 521 along the double side slides 501, and stops when the loading part 52 moves to the circular pressure block 413 of the grinding mechanism 4.

[0086] S4: Grinding automotive parts: At this time, the loading plate 521 is directly below the circular pressure block 413. The starting cylinder 401 uses the pressing part 40 to hold the loading plate 521 in place. Then, the blower 404, the first water pump 422, the second water pump 425, and the stirring motor 423 are started. The feeding part 42 provides abrasive to the pressing part 40. The pressing part 40 passes the abrasive into the grinding part 41. The feeding part 42 will continuously mix the new and old abrasive and continuously supply material to complete the grinding of the fuel injector 524 in the loading plate 521.

[0087] S5: Cleaning and collection of automotive parts: When the conveyor belt 502 is restarted and the polished loading section 52 is moved along the double slide rails 501 to the tilting slide rail 53, the third water pump 702 is started and water is sprayed through the high-pressure nozzle 704 to wash the abrasive adhering to the loading section 52. The fuel injector 524 will also be poured into the water tank 701. After rinsing is completed, the loading section 52 completes the transport of the fuel injector 524.
