Description

Technical Field

[0001] The invention specifically relates to the technical field of cylinder head fuel injection nozzle hole processing, in particular to a diesel engine cylinder head fuel injection nozzle hole processing technology. Background Art

[0002] The fuel injection nozzle hole is an important part of the diesel engine cylinder head, which is used to inject fuel into the cylinder for combustion; its processing quality directly affects the performance and reliability of the diesel engine;

[0003] At present, the conventional injection nozzle holes are processed by laser, electric spark and machining. However, the conventional processing method achieves stability during processing by supporting the injection nozzle, but this will cause damage to the surface of the injection nozzle, causing the injection nozzle to leak during use. In addition, the conventional clamping device can only clamp one workpiece during processing, so the workpiece needs to be frequently disassembled and installed during processing, and continuous processing cannot be effectively achieved, which will result in low work efficiency.

[0004] Chinese patent application number CN202321346512.4 discloses a diesel cylinder head injector hole processing device, comprising a base, a hydraulic rod is fixed on the upper surface of the base, a positioning plate is fixed on the upper surface of the base and located on the side of the hydraulic rod, and the positioning plate is L-shaped, and both sides of the outer wall of the positioning plate are provided with a slide groove, and both sides of the outer wall of the positioning plate are slidably installed with an annular sleeve through the slide groove, and the inside of the two annular sleeves is penetrated by an air pipe;

[0005] Although the structure in the above patent can realize the processing of the injector hole, the injector in the above patent needs to be loaded and clamped manually, and the spacing is adjusted by rotating the two clamping plates through the forward and reverse threads. Then the user places the injector on the upper part of the inside of the two clamping plates, and then rotates the second threaded rod to clamp and fix the position through the injector. Although the fixing effect can be achieved, it cannot effectively ensure that the position of the workpiece is the same each time during the fixing process, so the position of the workpiece needs to be adjusted, which makes the working efficiency of the equipment in the above patent low, and the workpiece plate in the above patent can only clamp one workpiece, so it is necessary to frequently replace the processed workpiece with the workpiece to be processed, and the continuous work effect cannot be effectively achieved.

[0069] Furthermore, after the placement is completed, the push rod of the electric push cylinder 8 installed on the inclined surface of the mounting block 7 drives the extension rod 116 to move along the L-shaped groove 111 provided on the fixed plate 110, so that the extension rod 116 drives the movable rod 113 to move upward through the U-shaped frame 114, and the movable rod 113 drives the movable frame 35 and the top block 33 to move upward, and the edge of the top block 33 contacts the two inner support blocks 31, so that the two inner support blocks 31 can effectively support the injector 5 internally, thereby ensuring the stability of the injector 5 during processing;

[0076] By adopting the above technical solution, the processed injector 5 is rotated to one side of the baffle 6 installed on the workbench 1 through the rotation of the turntable 30, and the baffle 6 blocks the extension rod 116, so that the extension rod 116 moves downward. When the extension rod 116 moves downward, the U-shaped frame 114 drives the movable rod 113 and the movable frame 35 to separate the top block 33 from the two inner support blocks 31, so that the two inner support blocks 31 release the injector 5, and automatic unloading is achieved through the mechanical clamp 10.

[0077] The working principle of the present invention is as follows: when in use, the fuel injector 5 is automatically placed at the top of the rotating ring 32 by the mechanical clamp 10, and the first rotating wheel 93 and the second rotating wheel 94 are synchronously rotated by the driving motor 2 to rotate the two matching wheels 91, so as to rotate the fuel injector 5 to be processed to the bottom of the clamp 47, and the top spray hole of the fuel injector 5 is processed by the drill bit.

[0079] After the placement is completed, the push rod of the electric push cylinder 8 installed on the inclined surface of the mounting block 7 drives the extension rod 116 to move along the L-shaped groove 111 opened on the fixed plate 110, so that the extension rod 116 drives the movable rod 113 to move upward through the U-shaped frame 114, and the movable rod 113 drives the movable frame 35 and the top block 33 to move upward, and the edge of the top block 33 contacts the two inner support blocks 31, so that the two inner support blocks 31 can effectively support the fuel injector 5 internally, thereby ensuring the stability of the fuel injector 5 during processing;

[0080] The driven rotating wheel 99 is driven to rotate by the driving motor 2, so that the two matching wheels 91 drive the first rotating wheel 93 and the second rotating wheel 94 to rotate in opposite directions. Since the diameter of the first driving gear 96 is larger than the diameter of the driven gear 34, the rotating ring 32 drives the nozzle 5 to rotate at a speed greater than the speed of the main rotating shaft 97 driving the rotating disk 30. In this way, the processing quality of the nozzle 5 spray hole is effectively guaranteed during processing.

[0081] By rotating the turntable 30, the fuel injector 5 is rotated to the bottom of the cartridge 47, and the stepping motor 44 drives the second driving gear 42 to mesh with the tooth plate 43, so that the tooth plate 43 drives the mounting frame 46 and the cartridge 47 to move up and down along the guide rod 45, so that the cartridge 47 drives the drill to process the fuel injection hole on the top of the fuel injector 5;

[0082] The processed fuel injector 5 is rotated to one side of the baffle 6 installed on the workbench 1 through the rotation of the turntable 30, and the baffle 6 blocks the extension rod 116, so that the extension rod 116 moves downward. When the extension rod 116 moves downward, the U-shaped frame 114 drives the movable rod 113 and the movable frame 35 to separate the top block 33 from the two inner support blocks 31, so that the two inner support blocks 31 release the fuel injector 5, and the mechanical clamp 10 realizes automatic unloading;
