Description

Technical Field

[0001] The present invention relates to the technical field of fuel injector processing, and particularly to a local quenching device for a motorcycle fuel injector bushing. Background Art

[0002] A fuel injector is a precision device with very high processing accuracy, requiring a large dynamic flow range, strong anti-blocking and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU and precisely controls the fuel injection volume. The spray characteristics of the fuel injector include atomization particle size, oil mist distribution, oil spray direction, spray range, and diffusion cone angle, etc. These characteristics should meet the requirements of the diesel engine combustion system to enable the formation and perfect combustion of the air-fuel mixture and obtain higher power and thermal efficiency.

[0003] The fuel injector bushing is installed in the cylinder head, and a water cavity for cooling is formed between the outside and the cylinder head. The fuel injector is installed inside the fuel injector bushing, and an injector nozzle for controlling fuel injection is installed at the lower end of the fuel injector. At present, the intensification degree of diesel engines is getting higher and higher, and the thermal load of the fuel injector is also getting larger. The fuel injector nozzle has relatively strict requirements for the temperature range, generally from more than 100 degrees Celsius to about 200 degrees Celsius.

[0004] At present, the fuel injector bushing is a thin-walled cylindrical structure. When quenching it, the thin-walled short bushing has been troubled by the difficulty of large processing deformation. During the quenching process, it is very difficult to meet the technical requirements of the parts due to the large deformation, and it is easy to generate deformation when clamped by the fixture. Summary of the Invention

[0005] To achieve the above purposes, the present invention is realized through the following technical solutions: A local quenching device for a motorcycle fuel injector bushing, including a base, the base has a base for carrying the quenching component, and clamping grooves opened on both sides of the outer surface of the base. A positioning plate is fixedly connected to the middle of the top of the base;

[0006] A beam frame, and a connecting shaft is fixedly connected and slidably connected inside the beam frame. A heating column core is fixedly connected to the lower surface of the beam frame through the connecting shaft;

[0007] A cooling component, and a connecting fastener is fixedly connected to the bottom of the cooling component;

[0008] A stabilizing component, which is used for the protective support of the beam frame, and connecting blocks are fixedly connected to both ends of the stabilizing component;

[0009] A jacket component, and a sleeve hole is opened on the surface of the jacket component;

[0010] Both sides of the outer surface of the base are fixedly connected to the connecting blocks at the bottom of the stabilizing component through clamping grooves. The top of the stabilizing component is fixedly connected to the beam frame through the connecting blocks. A connecting shaft is slidably connected inside the beam frame, and a heating column core is fixedly connected to the outer surface of the connecting shaft. The middle of the top of the base is fixedly connected to the connecting fastener at the bottom of the cooling component through a positioning plate. The inner surface of the cooling component is rotationally connected to the jacket component through sleeving; the staff sleeved the bushing on the surface of the heating column core, and then started the heating equipment to heat the bushing with the heating column core. After the heating is completed, the staff controls the connecting shaft to move downward on the surface of the beam frame, so that the heating column core drives the bushing to move downward with the connecting shaft into the cooling component, and then quenches the high-temperature bushing by cooling.

[0011] Among them, the cooling component includes a cooling pool, which is fixedly connected to the positioning plate in the middle of the top of the base through a connecting fastener. A rotating shaft is rotationally connected inside the cooling pool. There are two groups of the rotating shafts, and the two groups of rotating shafts are symmetrically arranged with the beam frame as the axis. A sleeve ring is fixedly connected to the middle of the opposite surfaces of the rotating shafts. A through rod is fixedly connected to the inner surface of the sleeve ring. The connecting shaft drives the heating column core and the bushing sleeved on its surface to move downward above the cooling pool. When the staff is present, at this time, the staff pushes the side plates to both sides. The side plates and the extension plates drive the bottom through rods, sleeve rings and rotating shafts to turn outward at both ends of the cooling pool, so that the convex blocks are separated from the grooves. At the same time, the jacket component arranged in the convex blocks and the grooves is pushed up with the outward-turned side plates, so as to support under the descending bushing and facilitate pre-fixing of the bushing.

[0012] Preferably, an extension plate is fixedly connected to the top of the through rod, a side plate is fixedly connected to the upper surface of the extension plate, a groove is fixedly connected to the outer surface of the side plate, and a convex block is movably connected to the inner surface of the groove. After the bushing moves downward and contacts the jacket component, the staff pushes the side plates inward. The side plates and the extension plates drive the bottom through rods, sleeve rings and rotating shafts to turn inward at both ends of the cooling pool, so that the convex blocks are engaged with the grooves. At the same time, the jacket component arranged in the convex blocks and the grooves contracts inward with the inward-turned side plates to clamp the bushing to maintain the stability during quenching. Then, the staff injects water into the cooling pool according to the part of the bushing that needs to be quenched, so as to perform local quenching on the bushing.

[0013] Preferably, there are two groups of the jacket components, and the two groups of the jacket components are symmetrically arranged with the beam frame as the center. The jacket component includes a rotating rod, and the rotating rods are respectively fixedly connected between the opposite surfaces of the convex blocks and the grooves. A circular connecting plate is sleeved on the outer surface of the rotating rod. The rotating rods respectively fix the circular connecting plates between the opposite surfaces of the convex blocks and the grooves. By the staff rotating the rotating shaft to change the position between the convex blocks and the grooves, the bushing is fixed.

[0014] Preferably, an extension rod is fixedly connected to the outer surface of the circular connection plate, a triangular sticker frame is fixedly connected to the lower surface of the circular connection plate, a connecting rod is fixedly connected between the opposite surfaces of the triangular sticker frame, and the triangular sticker frame is fixedly connected to the circular connection plate through the extension rod. When the rotating shaft turns outwards, the circular connection plate and the limiting plate are jacked upwards. At this time, the descending bushing is placed above the two limiting plates. As the staff pushes the rotating shaft inwards, the circular connection plate and the limiting plate turn inwards. Since the limiting plate is located below the bushing, after turning, the circular connection plate is displaced above the bushing, so that the bushing is limited between multiple triangular sticker frames. Then, the staff controls the connecting shaft to move upwards, so that the heating column core is separated from the bushing, and the bushing is clamped in the triangular sticker frame, so as to facilitate the cooling quenching of the bushing.

[0015] Preferably, a limiting plate is fixedly connected to the surface of the end of the extension rod far away from the circular connection plate, and the upper surface of the limiting plate is fixedly connected to the triangular sticker frame through the extension rod.

[0016] Preferably, the triangular sticker frame includes a buckle, the buckle is fixedly connected to the surfaces of the circular connection plate and the limiting plate, a sticker plate is fixedly connected to the outer surface of the buckle, an external connection plate is fixedly connected to the outer surface of the sticker plate, and the external connection plates are fixedly connected through a connecting rod between the opposite surfaces. The bushing is a thin-walled cylindrical structure. When the circular connection plate and the limiting plate turn over and clamp the bushing, the radian on the surface of the cylindrical bushing fits with the V-shaped plate. The V-shaped plate moves inwards with the turning circular connection plate and the limiting plate. At this time, the V-shaped plate and the bushing are extruded, so that the V-shaped plate generates displacement so that the cavity formed between the V-shaped plates fits with the bushing, changes the bushing fixing method, prevents the bushing from falling off, avoids the deformation of the bushing caused by the fixture during quenching, and makes the contact area between the bushing and the liquid in the cooling pool more uniform when the bushing is cooled.

[0017] Preferably, a triangular plate is fixedly connected to the outer surface of the sticker plate, a V-shaped plate is fixedly connected to the outer surface of the triangular plate, and the V-shaped plate is adapted to the bushing.

[0018] Preferably, the stabilizing assembly includes a fixing frame, the fixing frame is fixedly connected to the clamping grooves on both sides of the outer surface of the base, a support frame is fixedly connected to the inside of the fixing frame, a bearing block is fixedly connected to the inside of the support frame, and a cross bar penetrates through the bearing block.

[0019] Preferably, the support frame includes a square plate, the square plate is fixedly connected to the base and the beam frame respectively through connecting blocks, a support seat is fixedly connected to the surface of the square plate, clamping plates are fixedly connected to both sides of the outer surface of the support seat, and the support seat is fixedly connected to both ends of the bearing block. The support frame supports on both sides of the beam frame and mounts the beam frame above the cooling assembly. The bent plates and the through blocks connected to both sides of the support seat connect the beam frame and the base to maintain the stability when the bushing descends.

[0020] Preferably, a card slot is formed on the surface of the card board, a through block is fixedly connected inside the card slot, a bent plate is fixedly connected to the surface of the through block, and a cross bar is fixedly connected between the opposite surfaces of the bent plate and a bearing block.

[0021] The present invention provides a local quenching device for a motorcycle fuel injector bushing. It has the following beneficial effects:

[0022] First, in this local quenching device for the motorcycle fuel injector bushing, the connecting shaft drives the heating column core and the bushing sleeved on its surface to descend above the cooling pool. When the staff is present, at this time, the staff will push the side plates to both sides. The side plates and the extension plates drive the bottom through rods, collar rings and rotating shafts to turn outward at both ends of the cooling pool, so that the convex blocks are separated from the grooves. At the same time, the clamping sleeve components arranged in the convex blocks and the grooves are lifted upward along with the outward-turned side plates, so as to support under the descending bushing and facilitate pre-fixing of the bushing.

[0023] Second, in this local quenching device for the motorcycle fuel injector bushing, after the bushing descends and contacts the clamping sleeve components, the staff pushes the side plates inward. The side plates and the extension plates drive the bottom through rods, collar rings and rotating shafts to turn inward at both ends of the cooling pool, so that the convex blocks are engaged with the grooves. At the same time, the clamping sleeve components arranged in the convex blocks and the grooves contract inward along with the inward-turned side plates to clamp the bushing and maintain the stability during quenching. Then, the staff injects water into the cooling pool according to the parts of the bushing that need to be quenched, so as to perform local quenching on the bushing.

[0024] Third, in this local quenching device for the motorcycle fuel injector bushing, when the rotating shaft turns outward, the round connecting plate and the limiting plate are lifted upward. At this time, the descending bushing is placed above the two limiting plates. As the staff pushes the rotating shaft inward, the round connecting plate and the limiting plate turn inward. Since the limiting plate is located below the bushing, after turning, the round connecting plate is displaced above the bushing, so that the bushing is limited between multiple triangular sticker frames. Then, the staff controls the connecting shaft to ascend, so that the heating column core is separated from the bushing, and the bushing is clamped in the triangular sticker frames, so as to facilitate cooling and quenching of the bushing.

[0025] Fourth, in this local quenching device for the motorcycle fuel injector bushing, since the bushing is a thin-walled cylindrical structure, when the round connecting plate and the limiting plate turn and clamp the bushing, the arc on the surface of the cylindrical bushing fits with the V-shaped plate. The V-shaped plate displaces inward along with the turning round connecting plate and limiting plate. At this time, the V-shaped plate is extruded by the bushing, so that the V-shaped plate is displaced to make the cavity formed between the V-shaped plates fit with the bushing, changing the bushing fixing method, preventing the bushing from falling off, avoiding deformation of the bushing caused by the fixture during quenching, and making the contact area between the bushing and the liquid in the cooling pool more uniform when the bushing is cooled.

[0026] V. The local quenching equipment for the motorcycle fuel injector bushing is supported on both sides of the beam frame through a support frame, and the beam frame is erected above the cooling component. The bent plates connected to both sides of the support seat and the through blocks connect the beam frame to the base to maintain the stability when the bushing descends.

The staff sleeved the bushing on the surface of the heating column core 6, and then started the heating device to heat the bushing with the heating column core 6. After the heating was completed, the staff controlled the connecting shaft 5 to move downward on the surface of the beam frame 1, so that the heating column core 6 drove the bushing to move downward with the connecting shaft 5 into the cooling assembly 3, and then quenched the high-temperature bushing by cooling.

[0044] Preferably, the stabilizing assembly 2 includes a fixing frame 23, the fixing frame 23 is fixedly connected in the clamping grooves on both sides of the outer surface of the base 4, a support frame 24 is fixedly connected inside the fixing frame 23, a bearing block 21 is fixedly connected inside the support frame 24, and a cross bar 22 penetrates through the bearing block 21.

[0045] Preferably, the support frame 24 includes a square plate 246 which is fixedly connected to the base 4 and the beam frame 1 respectively through connecting blocks.

[0047] Second embodiment, on the basis of the first embodiment, please refer to Figures 5 - 6 As shown, the cooling assembly 3 includes a cooling pool 35 which is fixedly connected to the positioning plate at the middle of the top of the base 4 through a connecting fastener. A rotating shaft 33 is rotatably connected to the inside of the cooling pool 35. There are two groups of the rotating shafts 33 which are symmetrically arranged with the beam frame 1 as the axis. A collar 37 is fixedly connected to the middle of the opposite surfaces of the rotating shafts 33. A through rod 32 is fixedly connected to the inner surface of the collar 37. The connecting shaft 5 drives the heating column core 6 and the bushing sleeved on its surface to descend above the cooling pool 35. When the staff is present, at this time, the staff will push the side plates 31 outwards. The side plates 31 and the extension plates 38 drive the bottom through rods 32, collars 37 and rotating shafts 33 to turn outwards at both ends of the cooling pool 35, so that the convex blocks 34 are separated from the grooves 36. At the same time, the clamping sleeve assemblies 7 arranged in the convex blocks 34 and the grooves 36 are jacked upwards along with the outwards-turning side plates 31, so as to support under the descending bushing and facilitate the pre-fixing of the bushing.

[0048] Preferably, an extension plate 38 is fixedly connected to the top of the through rod 32. Side plates 31 are fixedly connected to the upper surface of the extension plate 38. Grooves 36 are fixedly connected to the outer surfaces of the side plates 31. Convex blocks 34 are movably connected to the inner surfaces of the grooves 36. After the bushing descends and contacts the clamping sleeve assembly 7, the staff pushes the side plates 31 inwards. The side plates 31 and the extension plates 38 drive the bottom through rods 32, collars 37 and rotating shafts 33 to turn inwards at both ends of the cooling pool 35, so that the convex blocks 34 are fitted into the grooves 36. At the same time, the clamping sleeve assemblies 7 arranged in the convex blocks 34 and the grooves 36 contract inwards along with the inwards-turning side plates 31 to clamp the bushing and maintain the stability during quenching. Then, the staff injects water into the cooling pool 35 according to the parts of the bushing that need to be quenched, so as to perform local quenching on the bushing.

[0049] Third Embodiment. On the basis of the first and second embodiments, please refer to Figures 7 - 9 As shown, preferably, there are two sets of the jacket assemblies 7, and the two sets of the jacket assemblies 7 are symmetrically arranged with the beam frame 1 as the center. The jacket assembly 7 includes a rotating rod 71, and the rotating rod 71 is fixedly connected between the opposite surfaces of the convex block 34 and the groove 36 respectively. A circular connecting plate 72 is sleeved on the outer surface of the rotating rod 71. The rotating rod 71 fixes the circular connecting plate 72 between the opposite surfaces of the convex block 34 and the groove 36 respectively. By the operator rotating the rotating shaft 33 to change the position between the convex block 34 and the groove 36, the bushing is fixed.

[0050] Preferably, an extension rod 74 is fixedly connected to the outer surface of the circular connecting plate 72, a triangular sticker frame 73 is fixedly connected to the lower surface of the circular connecting plate 72, a connecting rod 76 is fixedly connected between the opposite surfaces of the triangular sticker frame 73, and the triangular sticker frame 73 is fixedly connected to the circular connecting plate 72 through the extension rod 74. When the rotating shaft 33 is turned outwards, the circular connecting plate 72 and the limiting plate 75 are jacked upwards. At this time, the descending bushing is placed above the two limiting plates 75. As the operator pushes the rotating shaft 33 inwards, the circular connecting plate 72 and the limiting plate 75 are turned inwards. Since the limiting plate 75 is located below the bushing, after turning, the circular connecting plate 72 is displaced above the bushing, so that the bushing is limited between multiple triangular sticker frames 73. Then the operator controls the connecting shaft 5 to move upwards, so that the heating column core 6 is separated from the bushing, and the bushing is clamped in the triangular sticker frames 73, facilitating the cooling quenching of the bushing.

[0051] Preferably, a limiting plate 75 is fixedly connected to the surface of the extension rod 74 away from the circular connecting plate 72, and the upper surface of the limiting plate 75 is fixedly connected to the triangular sticker frame 73 through the extension rod 74.

[0052] Preferably, the triangular sticker frame 73 includes a buckle 731, the buckle 731 is fixedly connected to the surfaces of the circular connecting plate 72 and the limiting plate 75, a sticker plate 735 is fixedly connected to the outer surface of the buckle 731, an external connecting plate 732 is fixedly connected to the outer surface of the sticker plate 735, and the external connecting plates 732 are fixedly connected through the connecting rod 76 between the opposite surfaces. The bushing is a thin-walled cylindrical structure. When the circular connecting plate 72 and the limiting plate 75 are turned to clamp the bushing, the arc on the surface of the cylindrical bushing fits with the V-shaped plate 734. The V-shaped plate 734 is displaced inwards as the turning circular connecting plate 72 and the limiting plate 75. At this time, the V-shaped plate 734 is squeezed by the bushing, so that the V-shaped plate 734 is displaced to facilitate the cavity formed between the V-shaped plates 734 to fit with the bushing, changing the bushing fixing method, preventing the bushing from falling off, avoiding the deformation of the bushing caused by the fixture during quenching, and making the contact area between the bushing and the liquid in the cooling pool 35 more uniform when the bushing is cooled.

[0053] Preferably, a triangular plate 733 is fixedly connected to the outer surface of the sticker plate 735, and a V-shaped plate 734 is fixedly connected to the outer surface of the triangular plate 733. The V-shaped plate 734 is adapted to the bushing.

[0054] During use, the worker sleeved the bushing on the surface of the heating column core 6, and then started the heating device to heat the bushing with the heating column core 6. After the heating was completed, the worker controlled the connecting shaft 5 to move downward on the surface of the beam frame 1, so that the heating column core 6 drove the bushing to move downward with the connecting shaft 5 into the cooling assembly 3, and then quenched the high-temperature bushing by cooling.

[0055] The connecting shaft 5 drives the heating column core 6 and the bushing sleeved on its surface to move downward above the cooling pool 35. When the worker is present, at this time, the worker pushes the side plates 31 to both sides. The side plates 31 and the extension plates 38 drive the bottom through rods 32, collar 37 and rotating shafts 33 to turn outward at both ends of the cooling pool 35, so that the convex blocks 34 are separated from the grooves 36. At the same time, the jacket assemblies 7 arranged in the convex blocks 34 and the grooves 36 are lifted upward with the outwardly turned side plates 31, so as to support under the descending bushing and facilitate pre-fixing of the bushing.

[0056] After the bushing moves downward and contacts the jacket assembly 7, the worker pushes the side plates 31 inward. The side plates 31 and the extension plates 38 drive the bottom through rods 32, collar 37 and rotating shafts 33 to turn inward at both ends of the cooling pool 35, so that the convex blocks 34 are engaged with the grooves 36. At the same time, the jacket assemblies 7 arranged in the convex blocks 34 and the grooves 36 contract inward with the inwardly turned side plates 31 to clamp the bushing to maintain stability during quenching. Then, the worker injects water into the cooling pool 35 according to the part of the bushing that needs to be quenched, so as to perform local quenching on the bushing.

[0057] The rotating rods 71 respectively fix the round connection plates 72 between the opposite surfaces of the convex blocks 34 and the grooves 36. The worker rotates the rotating shaft 33 to change the position between the convex blocks 34 and the grooves 36 to fix the bushing.

[0058] When the rotating shaft 33 turns outward, the round connection plate 72 and the limit plate 75 are lifted upward. At this time, the descending bushing is placed above the two limit plates 75. As the worker pushes the rotating shaft 33 inward, the round connection plate 72 and the limit plate 75 turn inward. Since the limit plate 75 is located below the bushing, after turning, the round connection plate 72 is displaced above the bushing, so that the bushing is limited between multiple triangular sticker frames 73. Then, the worker controls the connecting shaft 5 to move upward, so that the heating column core 6 is separated from the bushing, and the bushing is clamped in the triangular sticker frames 73, so as to facilitate cooling and quenching of the bushing.

[0059] The bushing is a thin-walled cylindrical structure. When the circular connecting plate 72 and the limiting plate 75 flip and clamp the bushing, the radian of the surface of the cylindrical bushing fits with the V-shaped plate 734. The V-shaped plate 734 displaces inwardly along with the flipping circular connecting plate 72 and the limiting plate 75. At this time, the V-shaped plate 734 squeezes the bushing, causing the V-shaped plate 734 to displace so that the cavity formed between the V-shaped plates 734 fits with the bushing, changing the fixing method of the bushing, preventing the bushing from falling off, avoiding deformation of the bushing caused by the fixture during quenching, and making the contact area between the bushing and the liquid in the cooling pool 35 more uniform when the bushing cools down.

[0060] The support frame 24 supports on both sides of the beam frame 1 and mounts the beam frame 1 above the cooling assembly 3. The bent plates 241 and the inserting blocks 243 connected to both sides of the support seat 244 connect the beam frame 1 and the base 4 to maintain the stability when the bushing descends.

[0061] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the scope of protection of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
