Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically to a grooving device and method for processing fuel injection pump gears. Background Technology

[0002] The fuel injection pump is the "heart" of a diesel engine, responsible for converting low-pressure diesel fuel into high-pressure fuel and supplying it to the injectors of each cylinder according to the timing, quantity, and sequence. It determines power, fuel consumption, and emissions. The fuel injection pump gear is an important component of the fuel injection pump. The fuel injection pump gear, also known as the fuel injection pump drive gear, is the core transmission component in the diesel engine fuel system responsible for transmitting power and ensuring fuel injection timing. It is usually located in the engine gear chamber and connects the crankshaft or camshaft to the fuel injection pump camshaft.

[0003] Publication No. CN112388072A discloses a grooving device for gear manufacturing, comprising a housing and gears. A first groove is formed on the surface of the housing. A slider is slidably connected inside the housing within the first groove. A first push block is fixedly connected to the bottom end of the slider. Drive shafts are arranged on both sides of the first push block. A first spring is fixedly connected to the surface of the first push block, and a first long rod is fixedly connected to the end of the first spring away from the first push block. This grooving device for gear manufacturing, by pressing a button on the surface of a tool changer, connects a metal ball at the bottom of the button to a metal block, disconnecting the current flowing through the electromorphic fluid, causing the electromorphic fluid to solidify into a liquid. By rotating the tool changer, a second push block on the inner gear surface disengages from a third groove on the outer gear surface.

[0004] Although the aforementioned applications and prior art allow for the selection of suitable cutting tools on the surface of the tool changing device, when grooving the fuel injection pump gear using the aforementioned applications and prior art, the gear vibrates during the subsequent grooving process when supported by the support rod, thus affecting the forming quality. Furthermore, when using the clamping mechanism to support the center of the gear, a large amount of debris is generated during the gear's processing. Even after processing, a small amount of debris remains attached. When the gear is on top of the debris, the gear shifts off the surface of the clamping mechanism, resulting in inconsistent grooving positions. Moreover, after clamping the gear with the clamping mechanism, the gear will still shift or jump on the surface of the clamping mechanism during the subsequent grooving process, thus affecting the processing quality. Therefore, this invention proposes a grooving device and method for processing fuel injection pump gears. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a grooving device and method for machining fuel injection pump gears. It offers advantages such as stable support, prevention of tilting, and prevention of bouncing. This solves the problems of the aforementioned applications and existing technologies, where, when grooving fuel injection pump gears, the gear vibrates during subsequent grooving due to the support rod, affecting the forming quality. Furthermore, when using a clamping mechanism to support the center of the gear, a large amount of debris is generated during machining, and even after processing, some debris remains. When the gear is on top of the debris, it shifts off-center from the surface of the clamping mechanism, resulting in inconsistent grooving positions. Moreover, even after clamping the gear, it still shifts or bounces on the surface of the clamping mechanism during subsequent grooving, further affecting the machining quality.

[0006] (II) Technical Solution To achieve the aforementioned objectives of stable support, prevention of tilting, and prevention of skewing, the present invention provides the following technical solution: a grooving device for machining fuel injection pump gears, comprising: a machining box and a grooving mechanism disposed inside the machining box. A guide table is fixedly connected inside the processing box, the grooving mechanism is slidably connected to the surface of the guide table, a support cylinder is fixedly connected inside the processing box, and a control panel is provided on the surface of the processing box; A limiting component is disposed inside the processing box to limit and support the gear to be slotted. The limiting component includes a fixed cylinder fixedly connected inside the processing box and three sliding arc plates slidably connected inside the processing box. A sliding disk is slidably connected inside the fixed cylinder. A tension rod is fixedly connected to the top of the sliding disk. Several hinge blocks are fixedly connected to the surface of the tension rod and the surface of the three sliding arc plates. The hinge blocks are connected to each other by connecting strips. An anti-tilting component is installed inside the processing box to prevent the wheel from tilting on the surface of the sliding arc plate when the limiting component supports the wheel; An anti-deviation component is installed inside the processing box to prevent the gear from shifting or jumping on the surface of the limiting component when the grooving mechanism grooves the gear.

[0007] Furthermore, the limiting component also includes two mounting cylinders fixedly connected inside the processing box. The two mounting cylinders are connected to the fixed cylinder through a first connecting pipe. A first pressure relief valve is provided on the surface of the first connecting pipe. An air inlet pipe is fixedly connected to the surface of each of the two mounting cylinders.

[0008] Furthermore, the anti-tilt assembly includes a sliding plate slidably connected inside two mounting cylinders and several guide rods fixedly connected inside the processing box. A lifting rod is fixedly connected to the top of the sliding plate, and a support arc block is fixedly connected to the top of the lifting rod. A first spring is fixedly connected between the top of the sliding plate and the inside of the mounting cylinder, and a pull rope is fixedly connected to the bottom of the sliding plate.

[0009] Furthermore, the anti-tilt assembly includes two baffles slidably connected inside the processing box. The processing box has a sliding groove inside. A second spring is fixedly connected between one side of the two baffles and the inner wall of the sliding groove. The end of the pull rope away from the slide plate is fixedly connected to the side of the baffle plate near the second spring.

[0010] Furthermore, the anti-deviation component includes a drive disc fixedly connected inside the processing box. The drive disc is connected to the fixed cylinder through a second connecting pipe. The surface of the second connecting pipe is provided with a second pressure relief valve and a solenoid valve. The second connecting pipe is connected to the drive disc through a third connecting pipe.

[0011] Furthermore, the anti-deviation assembly also includes two irregularly shaped toothed plates slidably connected inside the processing box, a drive rod rotatably connected inside the drive disk, a number of drive plates fixedly connected to the surface of the drive rod and inside the drive disk, and a drive gear fixedly connected to the surface of the drive rod and at the top of the drive disk, the drive gear meshing with the two irregularly shaped toothed plates for transmission.

[0012] Furthermore, a fixing box is fixedly connected to the top of each of the two irregular toothed plates. A telescopic rod is fixedly connected inside the fixing box. A return spring is provided inside the telescopic rod. An extrusion block is slidably connected inside the fixing box. An extrusion strip is fixedly connected to one side of the extrusion block. A limiting plate is fixedly connected to the end of the extrusion strip away from the extrusion block. Several limiting teeth are fixedly connected inside the limiting plate.

[0013] Furthermore, two vibrating cylinders are fixedly connected to the top of the limiting plate, and a squeezing plate is slidably connected inside each of the two vibrating cylinders. A squeezing rod is fixedly connected to the bottom of the squeezing plate, and a rubber pad is fixedly connected to the bottom of the squeezing rod. A connecting frame is fixedly connected to the top of the squeezing plate. The fixed box is connected to the two vibrating cylinders through an infusion tube, which extends into the interior of the connecting frame.

[0014] Furthermore, the fixed box is slidably connected inside the processing box, and the middle of the extrusion block and the fixed box is provided with extrusion liquid. The part of the infusion tube located between the connecting frame and the jumping cylinder can be extended and retracted.

[0015] The present invention also provides a grooving method for machining fuel injection pump gears, which specifically includes the following steps: Step 1: Connect the external air source to the air intake pipe, and then place the gear to be processed on the surface of the support cylinder; Step 2: The air source drives the anti-tilt component to operate, so that the anti-tilt component lifts the gear to be processed, thereby preventing debris inside the processing box from affecting the stability of the gear to be processed. Step 3: After the anti-tilt component lifts the gear, the anti-tilt component synchronously drives the limit component, so that the limit component supports and limits the gear. Step 4: After the limiting component limits the gear, the limiting component synchronously drives the anti-deviation component, so that the anti-deviation component fixes the surface and top of the gear, thereby preventing the gear from shifting and jumping during the grooving process. Step 5: After the guide table moves the grooving mechanism to the designated position, the grooving mechanism performs grooving on the gear.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a grooving device and method for machining fuel injection pump gears, which has the following beneficial effects: 1. The grooving device and method for machining fuel injection pump gears utilizes a limiting component to connect the air intake pipe of an external air source. The gear is then placed on the surface of a support cylinder, and air enters the interior of the mounting cylinder through the air intake pipe. When the threshold of the first pressure relief valve is reached, the air inside the mounting cylinder enters the interior of the fixed cylinder through the first connecting pipe, causing the air to drive the sliding disc to rise inside the fixed cylinder. This, in turn, causes the sliding disc to drive the hinge block to rise via a tension rod. During the rising process, the hinge block drives the sliding arc plate to slide inside the machining box via a connecting strip, allowing the sliding arc plate to expand and support the center hole of the gear, thereby achieving a stable support effect.

[0017] 2. The grooving device and method for machining the fuel injection pump gear, through the combined use of the limiting component and the anti-tilting component, when air enters the interior of the mounting cylinder through the air intake pipe, the air drives the lifting rod to rise inside the mounting cylinder through the sliding plate, causing the lifting rod to drive the support arc block to rise. During the rising process, the sliding plate pulls the blocking plate through the pull rope, so that the blocking plate does not obstruct the rise of the support arc block. During the rising process, the support arc block lifts the gear, so that there are no foreign objects on the contact surface between the support arc block and the gear, thereby keeping the gear in a horizontal state, thus achieving the effect of preventing tilting.

[0018] 3. The grooving device and method for machining fuel injection pump gears utilizes a combination of a limiting component and an anti-deviation component. When the air inside the fixed cylinder reaches the threshold of the second pressure relief valve, the air enters the drive disc through the second connecting pipe. This air drives the drive rod to rotate via the drive plate. The drive rod, in turn, drives two irregularly shaped toothed plates to move via the drive gear. The moving toothed plates then move the fixed box. As the fixed box moves, the extrusion block drives the extrusion strip and the limiting disc to move, causing the limiting teeth inside the limiting disc to engage with the teeth on the gear surface. With the continuous movement of the fixed box, the limiting disc, via the extrusion strip, drives the extrusion block to move inside the fixed box. This causes the extrusion block to deliver the extrusion fluid inside the fixed box to the inside of the jumping cylinder via a delivery pipe. The extrusion fluid then drives the extrusion rod and the rubber pad to move via the extrusion disc, thus supporting the top of the gear. Therefore, when the grooving mechanism grooves the gear, the gear will not deviate or jump, achieving the effect of preventing deviation and jumping.

In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 5 A grooving device for machining fuel injection pump gears includes: a machining box 1 and a grooving mechanism 121 disposed inside the machining box 1. The guide table 12 is fixedly connected inside the processing box 1. The grooving mechanism 121 is slidably connected to the surface of the guide table 12. The support cylinder 13 is fixedly connected inside the processing box 1. The control panel 11 is provided on the surface of the processing box 1. Limiting component 2 is installed inside the processing box 1 and is used to limit and support the gear to be slotted; The anti-tilting component 3 is installed inside the processing box 1 to prevent the wheel from tilting on the surface of the sliding arc plate 23 when the limiting component 2 supports the wheel. Anti-deviation component 4 is installed inside the processing box 1 to prevent the gear from shifting and jumping on the surface of the limiting component 2 when the grooving mechanism 121 grooves the gear. When it is necessary to slot the gear, connect the external air source to the limiting component 2, then place the gear on the surface of the support cylinder 13, support the center hole of the gear through the limiting component 2, and then move the grooving mechanism 121 to the designated position through the guide table 12, and perform grooving on the gear through the grooving mechanism 121. For a specific embodiment two, please refer to Figures 1 to 10 Based on the grooving device for machining fuel injection pump gears provided in Specific Embodiment 1, this embodiment provides a further technical solution: The anti-tilt assembly 3 includes a sliding plate 31 slidably connected inside two mounting cylinders 21 and several guide rods 32 fixedly connected inside the processing box 1. A lifting rod 311 is fixedly connected to the top of the sliding plate 31, and a support arc block 312 is fixedly connected to the top of the lifting rod 311. A first spring 313 is fixedly connected between the top of the sliding plate 31 and the interior of the mounting cylinder 21. A pull rope 314 is fixedly connected to the bottom of the sliding plate 31. The anti-tilt assembly 3 includes two baffle plates 33 slidably connected inside the processing box 1. The interior of the processing box 1 has a sliding... The sliding groove has a second spring 331 fixedly connected between one side of the two baffles 33 and the inner wall of the sliding groove. The end of the pull rope 314 away from the slide plate 31 is fixedly connected to the side of the baffle 33 near the second spring 331. The limiting assembly 2 includes two mounting cylinders 21 fixedly connected inside the processing box 1. The two mounting cylinders 21 are connected to the fixed cylinder 22 through a first connecting pipe 211. A first pressure relief valve 212 is provided on the surface of the first connecting pipe 211. An air inlet pipe 213 is fixedly connected to the surface of each of the two mounting cylinders 21. It should be noted that both the inner and outer bottom ends of the mounting cylinder 21 are provided with sealing materials. Therefore, when gas enters the interior of the mounting cylinder 21, the gas will not leak from the opening at the inner bottom end of the mounting cylinder 21. A scraper is fixedly connected to the top end of the baffle plate 33. When the baffle plate 33 moves, the scraper on the top of the baffle plate 33 can scrape off foreign objects at the bottom of the gear. When the support arc block 312 rises, the baffle plate 33 will not obstruct the rise of the support arc block 312. When it is necessary to prevent the gear from tilting on the surface of the limiting component 2, when the outside air is connected through the air inlet pipe 213, the outside air enters the interior of the mounting cylinder 21 through the air inlet pipe 213. The air drives the lifting rod 311 to rise inside the mounting cylinder 21 through the sliding plate 31, so that the lifting rod 311 drives the support arc block 312 to rise. During the rising process, the sliding plate 31 pulls the baffle plate 33 through the pull rope 314, so that the baffle plate 33 does not block the rise of the support arc block 312. During the rising process, the support arc block 312 lifts the gear, so that there are no foreign objects on the contact surface between the support arc block 312 and the gear, thereby keeping the gear in a horizontal state. Therefore, when the limiting component 2 supports the gear, the gear is always in a horizontal state. For a specific embodiment three, please refer to Figures 1 to 10 Based on the grooving device for machining fuel injection pump gears provided in Specific Embodiment 2, this embodiment provides a further technical solution: The limiting component 2 also includes a fixed cylinder 22 fixedly connected inside the processing box 1 and three sliding arc plates 23 slidably connected inside the processing box 1. A sliding disk 221 is slidably connected inside the fixed cylinder 22. A tension rod 222 is fixedly connected to the top of the sliding disk 221. Several hinge blocks 231 are fixedly connected to the surface of the tension rod 222 and the surface of the three sliding arc plates 23. The several hinge blocks 231 are connected to each other by connecting strips 232. It should be noted that a rotating gear is fixedly connected to the surface of the tension rod 222, a drive motor is fixedly connected inside the processing box 1, a rotating rod is fixedly connected to the output end of the drive motor, a rotating gear is fixedly connected to the surface of the rotating rod, the rotating gear meshes with the rotating gear, and the rotating gear and the rotating gear are always meshed when the tension rod 222 rises. When the gear needs to be supported and limited, air enters the interior of the mounting cylinder 21 through the air inlet pipe 213. When the threshold of the first pressure relief valve 212 is reached, the air inside the mounting cylinder 21 enters the interior of the fixed cylinder 22 through the first connecting pipe 211, causing the air to drive the sliding disc 221 to rise inside the fixed cylinder 22. This causes the sliding disc 221 to drive the hinge block 231 to rise through the tension rod 222. During the rising process, the hinge block 231 drives the sliding arc plate 23 to slide inside the processing box 1 through the connecting strip 232, so that the sliding arc plate 23 supports the center hole of the gear by expanding. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the grooving device for machining fuel injection pump gears provided in Specific Embodiment 3, this embodiment provides a further technical solution: The anti-deviation assembly 4 includes a drive disc 41 fixedly connected inside the processing box 1. The drive disc 41 is connected to the fixed cylinder 22 via a second connecting pipe 223. A second pressure relief valve 224 and a solenoid valve 225 are provided on the surface of the second connecting pipe 223. The second connecting pipe 223 is connected to the drive disc 41 via a third connecting pipe 411. The anti-deviation assembly 4 also includes two irregularly shaped toothed plates 42 slidably connected inside the processing box 1. A drive rod 412 is rotatably connected inside the drive disc 41. Several drive plates 413 are fixedly connected to the surface of the drive rod 412 and located inside the drive disc 41. A drive gear 414 is fixedly connected to the surface of the drive plate 41 and located on the top of the drive plate 41. The drive gear 414 meshes with two irregular toothed plates 42 for transmission. A fixed box 43 is fixedly connected to the top of each of the two irregular toothed plates 42. A telescopic rod 431 is fixedly connected inside the fixed box 43. A return spring is provided inside the telescopic rod 431. A pressing block 432 is slidably connected inside the fixed box 43. A pressing strip 433 is fixedly connected to one side of the pressing block 432. A limiting plate 434 is fixedly connected to the end of the pressing strip 433 away from the pressing block 432. A number of limiting teeth 435 are fixedly connected inside the limiting plate 434. When it is necessary to prevent the gear from shifting during the grooving process, when the air inside the fixed cylinder 22 reaches the threshold of the second pressure relief valve 224, the air inside the fixed cylinder 22 enters the drive disc 41 through the second connecting pipe 223, causing the air to drive the drive rod 412 to rotate through the drive plate 413. When the drive rod 412 rotates, it drives the two irregular tooth plates 42 to move through the drive gear 414. When the irregular tooth plates 42 move, they drive the fixed box 43 to move. When the fixed box 43 moves, it drives the extrusion strip 433 and the limiting disc 434 to move through the extrusion block 432. This causes the limiting teeth 435 inside the limiting disc 434 to engage with the teeth on the surface of the gear. Since the limiting teeth 435 engage with the teeth on the surface of the gear, when the grooving mechanism 121 grooves the gear, the gear will not shift or rotate on the surface of the sliding arc plate 23, thus ensuring the quality of the grooving. For a specific implementation example, please refer to Implementation Example 5. Figures 1 to 16 Based on the grooving device for machining fuel injection pump gears provided in Specific Embodiment 4, this embodiment provides a further technical solution: Two vibrating cylinders 44 are fixedly connected to the top of the limiting plate 434. Squeezing plates 441 are slidably connected inside the two vibrating cylinders 44. Squeezing rods 442 are fixedly connected to the bottom of the squeezing plates 441. Rubber pads 443 are fixedly connected to the bottom of the squeezing rods 442. A connecting frame 444 is fixedly connected to the top of the squeezing plates 441. The fixed box 43 is connected to the two vibrating cylinders 44 through an infusion tube 445. The infusion tube 445 extends into the interior of the connecting frame 444. The fixed box 43 is slidably connected inside the processing box 1. Squeezing liquid is provided in the middle of the squeezing block 432 and the fixed box 43. The part of the infusion tube 445 located between the connecting frame 444 and the vibrating cylinders 44 can be extended and retracted. It should be noted that by opening the solenoid valve 225, one end of the second connecting pipe 223 is closed, allowing air inside the second connecting pipe 223 to enter the drive disc 41 through the third connecting pipe 411. This air then drives the drive rod 412 to reverse direction via the drive plate 413, thereby restoring the fixed box 43 to its initial state. Therefore, when the drive motor starts, the limit teeth 435 and the rubber pad 443 will not obstruct the rotation of the gears. Furthermore, a third spring is fixedly connected between the top of the extrusion disc 441 and the inner wall of the jumping cylinder 44. (See attached instruction manual.) Figure 7 The middle extrusion rod 442 is in the extended state; When it is necessary to prevent the gear from jumping during the grooving process, as the fixed box 43 moves continuously, the limiting plate 434 drives the extrusion block 432 to move inside the fixed box 43 through the extrusion bar 433. This causes the extrusion block 432 to transport the extrusion fluid inside the fixed box 43 to the inside of the jumping cylinder 44 through the infusion pipe 445. The extrusion fluid then drives the extrusion rod 442 and the rubber pad 443 to move through the extrusion plate 441. This causes the rubber pad 443 to support the top of the gear. As a result, when the grooving mechanism 121 grooves the gear, the gear will not jump, thus ensuring the quality of the grooving. In a specific embodiment six, the present invention also provides a grooving method for machining fuel injection pump gears, which specifically includes the following steps: Step 1: Connect the external air source to the air intake pipe 213, and then place the gear to be processed on the surface of the support cylinder 13; Step 2: The air source drives the anti-tilt component 3 to operate, so that the anti-tilt component 3 lifts the gear to be processed, thereby preventing the inside of the processing box 1 from containing debris that affects the stability of the gear to be processed. Step 3: After the anti-tilt component 3 lifts the gear, the anti-tilt component 3 synchronously drives the limiting component 2, so that the limiting component 2 supports and limits the gear. Step 4: After the limiting component 2 limits the gear, the limiting component 2 synchronously drives the anti-deviation component 4, so that the anti-deviation component 4 fixes the surface and top of the gear, thereby preventing the gear from shifting and jumping during the grooving process. Step 5: After the guide table 12 moves the grooving mechanism 121 to the designated position, the grooving mechanism 121 performs grooving on the gear.
