Description

Technical Field

[0001] This application relates to the field of common rail technology for fuel, and in particular to a feeding mechanism for common rail processing. Background Technology

[0002] The common rail fuel system is a crucial component of an automotive engine's fuel injection system. It stores fuel at high pressure in the fuel rail, precisely controlling the injectors to inject fuel into the cylinders, thereby improving engine power, reducing fuel consumption, and lowering emissions. The feeding mechanism for common rail machining is responsible for accurately and stably transporting raw materials or semi-finished products to the machining station during the common rail production process. The feeding mechanism provides fundamental support for common rail machining, ensuring the accuracy and efficiency of workpiece transport, and directly impacting the machining quality and production efficiency of the common rail system. A search revealed Chinese patent publication number CN211638433U, which discloses a guiding device for processing a common rail fuel pipe. The device includes a base, a support plate, a limiting groove, a push rod motor, a guide plate, a connecting plate, a groove, a telescopic rod, a clamping plate, a spring, and guide holes. The support plate is fixed to the center of the top of the base. The top of the support plate has symmetrically arranged limiting grooves. A guide plate is located directly above the support plate. Push rod motors are fixed to the four corners of the top of the base. The output shaft of the push rod motor is fixedly connected to the bottom of the connecting plate. The bottom of the guide plate has symmetrically arranged grooves directly above the limiting grooves. The surface of the guide plate has guide grooves equidistantly spaced above the limiting grooves. There are four sets of guide grooves. Drilling the common rail fuel pipe through the guide holes can save time adjusting the position during drilling, improving the processing efficiency. Furthermore, drilling the common rail fuel pipe through the guide holes can prevent the drill bit from shifting during drilling, improving processing accuracy. In existing technologies, some common rail machining feeding mechanisms lack a dedicated cleaning mechanism after completing the common rail grinding process, resulting in metal shavings remaining in the surface gaps and internal channels of the common rail. These shavings are difficult to remove naturally and can easily scratch the workpiece, clog fuel lines or injection ports, affecting the quality and lifespan of the common rail, potentially interfering with engine operation, causing fuel system malfunctions, and creating safety hazards. Utility Model Content

[0003] The purpose of this application is to provide a feeding mechanism for common rail fuel processing, which aims to improve the problem of residual metal shavings in the common rail fuel of automobiles due to the lack of a cleaning mechanism in some existing devices after grinding.

[0004] The feeding mechanism for common rail fuel processing provided in this application adopts the following technical solution: a feeding mechanism for common rail fuel processing includes a support block, a cleaning mechanism is fixedly connected to the front side of the support block, a fixing mechanism is fixedly connected to the inside of the support block, and a common rail fuel body is slidably connected to the front side of the support block. The cleaning mechanism includes two fixed blocks. The rear sides of the two fixed blocks are fixedly connected to the front side of the support block. Multiple side spray holes are fixedly connected to the adjacent sides of the two fixed blocks. A water supply pipe is fixedly connected inside the distant sides of the two fixed blocks. Two pressure cylinders are fixedly connected to the front side of the support block. A water washer is fixedly connected to the bottom of the pressure cylinder. An air washing assembly is fixedly connected inside the distant sides of the two fixed blocks. Through the above technical solution: the support block combined with the fixing mechanism can stably limit the position of the common rail fuel body, ensuring accurate feeding. In the cleaning mechanism, the side spray holes and water supply pipes of the fixing block and the water washer driven by the cylinder work together to achieve water washing, and the air washing component supplements the air washing, which can thoroughly clean the common rail fuel, reduce interference from processing impurities, and improve processing quality and subsequent performance.

[0005] Preferably, the fixing mechanism includes a rotary cylinder, the outside of which is fixedly connected to the inside of the support block, a pressure rod is fixedly connected to the drive end of the rotary cylinder, and a rubber pad is fixedly connected to the side of the pressure rod near the support block. By adopting the above technical solution, the driving force provided by the rotary cylinder fixed inside the support block can drive the pressure rod to rotate precisely, enabling rapid fixing and loosening of the common rail fuel body, thus improving operational efficiency. Simultaneously, the rubber pad on one side of the pressure rod prevents direct contact between the pressure rod and the common rail fuel body, effectively preventing scratches on the workpiece surface and ensuring the appearance and quality of the processed common rail fuel system.

[0006] Preferably, the air washing assembly includes two drive cylinders, the rear sides of the two drive cylinders are fixedly connected to the front side of the support block, the drive ends of the two drive cylinders are fixedly connected to the inside of the fixed block, a plurality of slide rails are fixedly connected to the front side of the support block, the outside of the slide rails are slidably connected to the inside of the fixed block, two air pipes are fixedly connected to the front side of the support block, a mounting block is fixedly connected to the top of the fixed block, and an air jet head is fixedly connected to the inside of the mounting block; By adopting the above technical solution, the drive cylinder can drive the fixed block to slide stably along the slide rail, facilitating the adjustment of the jet nozzle spacing according to the position of the common rail fuel body, thus improving cleaning adaptability. Air supply through the air pipe, passing through the jet nozzle, ensures precise jetting, and, combined with sliding adjustment, can thoroughly remove impurities from the workpiece, supplementing the cleaning effect of water washing, reducing processing interference, and further ensuring the processing quality and subsequent stability of the common rail fuel system.

[0007] Preferably, the common rail fuel body includes a common rail fuel housing, the common rail fuel housing is fixedly connected to the outside of a plurality of injection ports, and a central through hole is formed inside the top side of the common rail fuel housing; By adopting the above technical solution, the common rail housing serves as the basic carrier, stably supporting all components. Multiple externally fixed injection ports enable uniform and precise fuel injection, ensuring fuel supply efficiency; the central through-hole inside the top side facilitates fuel flow and subsequent processing and assembly. The overall structure not only meets the core usage requirements of the common rail system but also provides convenience for processing and installation, helping to improve the operating performance of the fuel system.

[0008] Preferably, the fixing block has a sliding groove inside, and the slide rail is slidably connected to the inside of the sliding groove. By adopting the above technical solution, the slide rail on the front side of the support block forms a precise sliding fit, which not only provides stable guidance for the movement of the fixed block, avoiding deviation that would affect the jet position accuracy of the air washing component, but also reduces frictional loss during sliding, extending the service life of the components. At the same time, the stable sliding structure ensures smooth adjustment of the fixed block during air washing, helping to improve the cleaning effect and processing efficiency of the fuel common rail body.

[0009] Preferably, the bottom of the jet head has an air outlet, and the mounting block is an L-shaped block; By adopting the above technical solution, the jet nozzle at the bottom of the jet head allows the airflow to act more precisely on the area of ​​the common rail fuel body to be cleaned, avoiding airflow dispersion and reducing the cleaning effect; the mounting block adopts an L-shaped structure, which can flexibly adapt to the installation position of the fixing block and the jet head, ensuring a stable connection between the two, and rationally planning the spatial layout to avoid component interference, helping the air washing component to complete the cleaning operation stably and efficiently, and ensuring the processing quality of the common rail fuel.

[0010] Preferably, the rubber pad has anti-slip teeth on its outer surface, and the anti-slip teeth are in contact with the outer surface of the common rail fuel body; By adopting the above technical solution, the anti-slip teeth on the outside of the rubber pad fit snugly against the outside of the common rail fuel body, significantly increasing the friction between them. This prevents the common rail fuel from shifting due to vibration during processing or cleaning, ensuring positioning stability. Simultaneously, the rubber material itself can buffer the pressure of the pressure bar, and the anti-slip tooth design enhances the fixing effect without damaging the workpiece surface, balancing fixing reliability and product integrity, and helping to improve processing accuracy.

[0011] Preferably, the front side of the support block is provided with a placement groove, and the outer side of the common rail fuel body is in contact with the inner wall of the placement groove; By adopting the above technical solution, the placement groove on the front side of the support block fits snugly against the exterior of the common rail fuel body, which can initially position the workpiece and prevent it from shaking randomly, laying the foundation for the stable fixation of the subsequent fixing mechanism. At the same time, the snug structure can distribute the force on the workpiece, reduce local pressure damage during processing or cleaning, and also help to calibrate the workpiece position, improve the accuracy of feeding and processing, and ensure a smooth overall processing flow.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the common rail body is cleaned by a cleaning mechanism. Multiple side spray holes fixed inside the fixing block enable the device to accommodate various types of common rails. After cleaning, the air washing assembly fixed to the front of the support block discharges the residual water inside the common rail body through air washing. The above structure ultimately improves the finished quality of the common rail.

[0013] 2. In this utility model, the rotary cylinder fixed inside the support block is activated, which drives the pressure rod fixed at the drive end of the rotary cylinder to rotate, so that the rubber pad fixed on the side near the support block comes into contact with the fuel common rail body. The anti-slip teeth set on the side near the fuel common rail body assist in positioning the fuel common rail body, providing assistance for fixing the fuel common rail body, thereby improving the production efficiency of the fuel common rail.

[0015] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4This application will be described in further detail below.

[0016] Reference Figure 1 , Figure 3 The present invention provides an embodiment of a common rail fuel processing feeding mechanism, comprising a support block 1, which is the basic component of the entire feeding mechanism and serves to support, fix and provide sliding space. A cleaning mechanism 2 is fixedly connected to the front side of the support block 1, which cleans the common rail fuel body 5 by water washing and air washing. A fixing mechanism 4 is fixedly connected inside the support block 1 to ensure that the common rail fuel body 5 does not shift during cleaning or other processing. The common rail fuel body 5 is slidably connected inside the front side of the support block 1. The common rail fuel body 5 is the core part of the feeding mechanism and is responsible for the storage and supply of fuel. Specifically, the fuel common rail body 5 enters the front side of the support block 1 and slides along its interior to a preset position; the fixing mechanism 4 is activated to fix the fuel common rail body 5; then the cleaning mechanism 2 operates to clean the fuel common rail body 5; after cleaning, the fixing mechanism 4 is released, and the fuel common rail body 5 slides out from the front side of the support block 1, completing one feeding and related processing procedure.

[0017] The cleaning mechanism 2 includes two fixed blocks 21. As one of the core components of the cleaning mechanism 2, the fixed blocks 21 play a role in fixing and guiding. The rear sides of the two fixed blocks 21 are fixedly connected to the front side of the support block 1. Multiple side spray holes 22 are fixedly connected to the adjacent sides of the two fixed blocks 21. The side spray holes 22 are distributed on the adjacent sides of the fixed blocks 21 and their function is to spray water evenly to achieve the effect of initial cleaning of the surface of the fuel common rail body 5. Water supply pipes 23 are fixedly connected inside the distant sides of the two fixed blocks 21. The function of the water supply pipes 23 is to connect the water source from the support block 1 to the fixed blocks 21. The design of the water pipe must ensure smooth water flow and prevent leakage. Two pressure cylinders 24 are fixedly connected to the front side of the support block 1. A water washer 25 is fixedly connected to the bottom of the pressure cylinder 24. The pressure cylinder 24 is used to drive the water washer 25 to move to a suitable position to ensure that the water washer 25 can fully contact the surface of the fuel common rail body 5. An air washing assembly 3 is fixedly connected inside the two fixed blocks 21 on the far side. After the water washing is completed, the air washing assembly 3 uses high-pressure gas to clean the water or impurities on the surface of the fuel common rail body 5 to ensure thorough cleaning. Specifically, during the operation of the cleaning mechanism 2, water is first supplied to the interior of the fixed block 21 through the water supply pipe 23. The water flows out through the side spray hole 22 on the side of the fixed block 21 to perform a preliminary water wash on the fuel common rail body 5. At the same time, the pressure cylinder 24 is started, and its drive end drives the water washer 25 to move to a suitable position to further wash the fuel common rail body 5. During or after the water washing process, the air washing component 3 starts to operate, working together with the water washing action of the side spray hole 22 and the water washer 25 to complete the cleaning operation of the fuel common rail body 5.

[0018] The air washing assembly 3 includes two drive cylinders 32. The drive cylinders 32 drive the piston to move by compressed air, thereby adjusting the position of the fixed block 21. The rear sides of the two drive cylinders 32 are fixedly connected to the front side of the support block 1. The drive ends of the two drive cylinders 32 are fixedly connected to the inside of the fixed block 21. Multiple slide rails 31 are fixedly connected to the front side of the support block 1. The outside of the slide rails 31 is slidably connected to the inside of the fixed block 21. Two air pipes 33 are fixedly connected to the front side of the support block 1. An mounting block 34 is fixedly connected to the top of the fixed block 21. An air jet head 35 is fixedly connected to the inside of the mounting block 34. The air jet head 35 blows compressed air onto the surface of the fuel common rail body 5 through the air jet port at its bottom to perform air washing. A sliding groove is opened inside the fixed block 21. The slide rails 31 and the sliding groove are mainly to ensure that the fixed block 21 can move smoothly along a specific trajectory during the air washing process. The outside of the slide rails 31 is slidably connected to the inside of the sliding groove. An air jet port is opened inside the bottom of the air jet head 35. The mounting block 34 is an L-shaped block. Specifically, when the gas washing assembly 3 is in operation, the drive cylinder 32 is started, which drives the fixed block 21 to slide along the sliding groove on the slide rail 31 to adjust its position. After the position is determined, the air pipe 33 delivers gas to the mounting block 34, which is then sprayed out from the bottom of the jet nozzle 35 inside the L-shaped mounting block 34 to perform gas washing on the fuel common rail body 5. During this period, the position of the fixed block 21 can be adjusted again by the drive cylinder 32 to complete the full gas washing.

[0019] Reference Figure 2 , Figure 4The fixing mechanism 4 includes a rotary cylinder 41, which is externally fixedly connected to the inside of the support block 1. A pressure rod 42 is fixedly connected to the drive end of the rotary cylinder 41. The rotary cylinder 41 and the pressure rod 42 work by rotating to move the pressure rod 42, thereby pressing the common rail fuel body 5. A rubber pad 43 is provided on one side of the pressure rod 42. The pressing action ensures that the common rail fuel body 5 does not shift during operation. The side of the pressure rod 42 closest to the support block 1 is fixedly connected to the rubber pad 43. The rubber pad 43 is used to achieve stable fixation of the common rail fuel body 5 by contacting its outer surface. The rubber pad 43 has anti-slip teeth on its outer surface. The anti-slip teeth can enhance the friction with the surface of the common rail fuel body 5 and prevent slippage. The anti-slip teeth fit snugly against the outer surface of the common rail fuel body 5. Specifically, when the fixing mechanism 4 is in operation, the rotary cylinder 41 inside the support block 1 starts first, and its drive end drives the pressure rod 42 to rotate towards the fuel common rail body 5. As the pressure rod 42 rotates, the rubber pad 43 on one side of the pressure rod 42 gradually approaches the fuel common rail body 5 until the anti-slip teeth on the outside of the rubber pad 43 are completely in contact with the outside of the fuel common rail body 5, thereby fixing the fuel common rail body 5. When it is necessary to release the fixation, the rotary cylinder 41 drives the pressure rod 42 to rotate in the opposite direction, causing the rubber pad 43 to separate from the fuel common rail body 5.

[0020] The common rail fuel body 5 includes a common rail fuel housing 51, which is the external structure of the common rail fuel body 5. It has high strength and corrosion resistance to withstand long-term erosion of fuel. Multiple injection ports 52 are fixedly connected to the outside of the common rail fuel housing 51. The injection ports 52 are multiple openings on the common rail fuel housing 51 for injecting fuel into different combustion units. A central through hole 53 is opened inside the top side of the common rail fuel housing 51. The central through hole 53 is a hole opened on the top side of the common rail fuel housing 51 for the entry and exit of liquid or gas to ensure smooth flow of fuel in the common rail body. A placement groove is provided on the front side of the support block 1. The outside of the common rail fuel body 5 is in contact with the inner wall of the placement groove. Specifically, during the operation of the device, the fuel common rail body 5 with the fuel common rail housing 51 is first placed in the placement groove on the front side of the support block 1, so that the outside of the fuel common rail body 5 is in contact with the inner wall of the placement groove. During the placement process, the multiple injection ports 52 on the outside of the fuel common rail housing 51 and the central through hole 53 on the top side enter the preset position together with the body. After the fuel common rail body 5 is stable in the placement groove, it can enter the subsequent processing steps such as fixing and cleaning.

[0021] The implementation principle of this application embodiment is as follows: the fuel common rail body 5 is placed into the feeding groove opened inside the support block 1, and then the rotary cylinder 41 fixed inside the support block 1 is started. The rotary cylinder 41 drives the pressure rod 42 fixed at the drive end of the rotary cylinder 41 to rotate, so that the anti-slip ring on the side of the pressure rod 42 near the fuel common rail body 5 fits against the outside of the fuel common rail body 5. The rubber material of the rubber pad 43 and the anti-slip teeth set on the side near the fuel common rail body 5 restrict the fuel common rail body 5, thereby facilitating the fixation of the fuel common rail body 5. During cleaning, the water spray pipe fixed to the top front side of the support block 1 and the multiple side water spray holes 22 fixed to the left and right ends of the front side of the support block 1 via the mounting block 34 spray water into the central through hole 53 on the top of the common rail fuel body 5 and the spray nozzle 52 on the outside. The side water spray holes 22 are numerous and can accommodate various models of common rail fuel. After rinsing, the drive cylinder 32 moves the jet nozzle of the jet head 35, which is fixed above the mounting block 34 via the air pipe 33 bracket, to directly above the common rail fuel body 5. The rapid flow of gas cleans the residual water droplets inside the common rail fuel body 5.

[0022] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
