Description

Technical Field

[0001] This utility model relates to a disassembly tool, specifically a diesel engine injector disassembly device. Background Technology

[0002] As the core component of the diesel engine combustion chamber, the performance of the diesel engine injector directly affects the normal operation of the diesel engine. In order to ensure the good operation of the diesel engine during daily use, it is necessary to regularly inspect, maintain and repair the diesel engine injector, which inevitably involves the disassembly of the diesel engine injector.

[0003] Currently, when disassembling diesel engine injectors, it is usually necessary to use a disassembly device to remove the diesel engine injector from the diesel engine. The existing disassembly device is a pry bar. When using a pry bar to remove a diesel engine injector, because the space around the diesel engine injector is extremely narrow, it is necessary to first remove the components on the diesel engine that are connected to the diesel engine injector and the components that affect the operating range of the pry bar. Then, the pry bar is used to pry the injector holder on the diesel engine injector until the diesel engine injector is pried off the diesel engine. However, using a pry bar to remove diesel engine injectors requires a large operating space. Therefore, before removing the injectors, it's usually necessary to disassemble numerous components around them, such as the intake manifold, exhaust manifold, valve cover, injector wiring harness, high-pressure fuel lines, valve rocker arm assembly, bridge pipe, and components within the pry bar's operating range, including the air conditioning pump belt, air conditioning pump, air conditioning pump mount, external wiring harness, coolant inlet pipe, and turbocharger intake manifold. This makes disassembling the injectors both time-consuming and labor-intensive, increasing the operator's workload and impacting efficiency. Furthermore, using a pry bar makes it difficult to align the force direction with the injector's removal direction, making operation extremely strenuous. The pry bar is also prone to slipping off the pry point, potentially damaging the injector and injuring the operator, seriously affecting safety. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a diesel engine injector disassembly device, thereby reducing labor intensity, improving disassembly efficiency, and enhancing safety during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a diesel engine injector disassembly device, comprising a claw mechanism capable of being locked at the bottom of the injector holder in the diesel engine injector, a guide rod mechanism detachably connected to the claw mechanism via a connecting mechanism, a sliding hammer mechanism slidably connected to the guide rod mechanism, and a limiting block detachably connected to the upper end of the guide rod mechanism for limiting the sliding hammer mechanism.

[0006] As a limitation of this utility model, the claw mechanism includes two hollow semi-cylindrical components with semi-annular grooves on their outer walls. The two hollow semi-cylindrical components are pressed together by elastic locking rings fitted on the two semi-annular grooves to form a hollow cylindrical component. A limiting sleeve for preventing the two hollow semi-cylindrical components from separating is fitted on the outer side of the hollow cylindrical component. An L-shaped claw is fixed at the relative position of the bottom of each of the two hollow semi-cylindrical components. The two L-shaped claws cooperate with each other to lock into the bottom of the injector holder in the diesel engine injector.

[0007] As a further limitation of this utility model, the hollow semi-cylindrical component located on the same side of the two hollow semi-cylindrical components and the two L-shaped claws are integrally formed with the L-shaped claws.

[0008] As a further limitation of this utility model, the connecting mechanism includes a dumbbell-shaped component that is detachably connected to the upper end of the hollow cylindrical component.

[0009] As a further limitation of this utility model, the guide rod mechanism includes a threaded rod threadedly connected to the connecting mechanism, a bottom nut threadedly connected to the threaded rod and pressing against the bottom surface of the connecting mechanism, a top nut threadedly connected to the threaded rod and pressing against the top surface of the connecting mechanism, and a guide rod body coaxially fixed to the top of the threaded rod.

[0010] As another limitation of this utility model, the sliding hammer mechanism includes a sliding block sleeved on the outside of the guide rod mechanism, which can slide along the length direction of the guide rod mechanism.

[0011] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0012] (1) This utility model is provided with a claw mechanism, a connecting mechanism, a guide rod mechanism, a sliding hammer mechanism, and a limiting block. The claw mechanism can be locked at the bottom of the injector holder in the diesel engine injector. When using this utility model, first lock the claw mechanism at the bottom of the injector holder and make the guide rod mechanism vertical. Then, hold the sliding hammer mechanism and repeatedly strike the limiting block. When the sliding hammer mechanism strikes the limiting block, it can generate an upward impact force on the limiting block. At this time, the claw mechanism can pull the diesel engine injector upward. After striking the limiting block multiple times, the diesel engine injector can be removed from the diesel engine. When using this utility model, only a small operating space is required. Usually, only a few components around the diesel engine injector need to be removed. This utility model can be used to complete the disassembly of the diesel engine injector. In addition, this utility model can apply a vertical upward pulling force to the diesel engine injector. The direction of the force is consistent with the direction of the force required to remove the diesel engine injector. It saves time and effort and can effectively reduce the labor intensity of the operator and improve the disassembly efficiency. Furthermore, this invention offers high safety, is less likely to damage diesel engine injectors or injure operators, and effectively improves the safety of its use.

[0013] (2) In this utility model, the claw mechanism, connecting mechanism, guide rod mechanism, sliding hammer mechanism and limiting block are detachably connected together. If the utility model is damaged after long-term use, the damaged components can be replaced separately, which can reduce the cost of use.

[0014] (3) The structural design of the claw mechanism, the connecting mechanism and the guide rod mechanism in this utility model is reasonable and ingenious. The claw mechanism adopts a structure combining two hollow semi-cylindrical components, an elastic locking ring, a limiting sleeve and two L-shaped claws. The connecting mechanism is a dumbbell-shaped component. The claw mechanism and the guide rod mechanism can be detachably connected together through the dumbbell-shaped component. The structure of the claw mechanism, the connecting mechanism and the guide rod mechanism is simple, the manufacturing cost is low and the assembly is convenient. When in use, the claw mechanism can be easily and quickly locked at the bottom of the injector holder in the diesel engine injector, which can effectively improve the convenience and practicality of this utility model.

[0015] (4) The hollow semi-cylindrical component and L-shaped claw in this utility model are integrally formed, which can effectively improve the structural strength and service life of this utility model.

[0016] In summary, this utility model has a reasonable structure, low manufacturing cost, is convenient to use, and is highly practical. It requires only a small operating space, typically only needing to disassemble a few components around the diesel engine injector to complete the disassembly. Furthermore, this utility model can apply a vertically upward pulling force to the diesel engine injector, with the direction of the force matching the direction required to remove the injector, saving time and effort, effectively reducing the labor intensity of operators and improving disassembly efficiency. In addition, this utility model is highly safe to use, unlikely to damage the diesel engine injector or injure the operator, effectively improving the safety of its use. This utility model is suitable for use when it is necessary to disassemble diesel engine injectors. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0024] Example 1: A diesel engine injector disassembly device

[0025] like Figure 1 , Figure 2As shown, this embodiment includes a claw mechanism that can be locked at the bottom of the injector holder 13 in the diesel engine injector, a guide rod mechanism that is detachably connected to the claw mechanism via a connecting mechanism, a sliding hammer mechanism 10 that is slidably connected to the guide rod mechanism, and a limiting block 11 that is detachably connected to the upper end of the guide rod mechanism for limiting the sliding hammer mechanism 10.

[0026] The chuck mechanism includes two hollow semi-cylindrical components 1 with semi-annular grooves 12 on the upper side of their outer walls. The two hollow semi-cylindrical components 1 are pressed together by elastic locking rings 3 fitted on the two semi-annular grooves 12 to form a hollow cylindrical component. A limiting sleeve 9 is fitted on the outer side of the hollow cylindrical component to prevent the two hollow semi-cylindrical components 1 from separating. An L-shaped chuck 2 is fixed at the relative position of the bottom of each of the two hollow semi-cylindrical components 1. The two L-shaped chucks 2 cooperate with each other to be locked at the bottom of the injector holder 13 in the diesel engine injector. Among the two hollow semi-cylindrical components 1 and the two L-shaped chucks 2, the hollow semi-cylindrical component 1 on the same side is integrally formed with the L-shaped chuck 2. It is necessary to ensure that when the two hollow semi-cylindrical components 1 are pressed together, the cavity between the two hollow semi-cylindrical components 1 and the two L-shaped chucks 2 can accommodate the part above the injector holder 13 in the diesel engine injector and the injector holder 13. Specifically, in this embodiment, the elastic locking ring 3 adopts an existing wire snap ring, which is a ring-shaped structure with an opening made of spring steel. It relies on its own elasticity to lock into the two semi-annular grooves 12. The cavity in the hollow semi-cylindrical component 1 includes a first semi-cylindrical cavity and a second semi-cylindrical cavity connected to the bottom of the first semi-cylindrical cavity. The size of the second semi-cylindrical cavity is larger than the size of the first semi-cylindrical cavity. When the two hollow semi-cylindrical components 1 are pressed together, the two first semi-cylindrical cavities form the first cylindrical cavity, and the two second semi-cylindrical cavities form the second cylindrical cavity. The L-shaped claw 2 includes a first arc-shaped plate and a second arc-shaped plate vertically fixed to the bottom of the first arc-shaped plate, wherein both the first arc-shaped plate and the second arc-shaped plate are quarter-circular arc plates. It should be noted that a relatively large force is required to separate the limiting sleeve 9 from the hollow cylindrical component.

[0027] The connecting mechanism includes a dumbbell-shaped component 4 detachably connected to the upper end of the hollow cylindrical component. Specifically, in this embodiment, the dumbbell-shaped component 4 includes two opposing disks and a connecting cylinder fixed between the two disks. The cross-sectional dimension of the connecting cylinder is smaller than that of the disks, and the connecting cylinder is inserted into the first cylindrical cavity.

[0028] The guide rod mechanism includes a threaded rod 5 threaded to the connecting mechanism, a bottom nut 6 threaded to the threaded rod 5 pressing against the bottom surface of the connecting mechanism, a top nut 7 threaded to the threaded rod 5 pressing against the top surface of the connecting mechanism, and a guide rod body 8 coaxially fixed to the top of the threaded rod 5. A limiting block 11 is threaded to the top of the guide rod body 8.

[0029] The sliding hammer mechanism 10 includes a sliding block sleeved on the outside of the guide rod mechanism, which can slide along the length direction of the guide rod mechanism, wherein the sliding block is a hollow cylindrical slider.

[0030] When using this embodiment, as Figure 3 As shown, the limiting sleeve 9 and the sliding hammer mechanism 10 are moved upward to expose the chuck mechanism, opening the chuck mechanism to the width of the diesel engine injector's maximum diameter, as shown. Figure 4 As shown, the diesel engine injector is slid downwards until the two L-shaped claws 2 in the claw mechanism are locked at the bottom of the injector holder 13 in the diesel engine injector. Then, the limiting sleeve 9 is placed on the outside of the hollow cylindrical component. Then, the sliding hammer mechanism 10 is held and repeatedly strikes the limiting block 11. When the sliding hammer mechanism 10 strikes the limiting block 11, it can generate an upward impact force on the limiting block 11. At this time, the claw mechanism can pull the diesel engine injector upward. After striking the limiting block 11 multiple times, the diesel engine injector can be removed from the diesel engine.

[0031] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
