Description

Technical Field

[0001] This utility model relates to the technical field of fuel injector body assembly processing, and in particular to a tooling for processing oblique flat internal threads in fuel injector body assemblies. Background Technology

[0002] Fuel injectors are crucial components in modern automotive engines. Patents such as CN104653374B (disclosed a split-type fuel injector body) and CN105065164B (disclosed a guide rod structure electronically controlled fuel injector) illustrate this. The fuel injector body assembly is a key component of the fuel injector; simply put, it's a valve, a precision assembly that controls fuel intake. During production, the fuel injector body assembly requires thread machining. This is typically achieved using an internal thread machining device disclosed in patent CN117564379A and an internal thread machining machine disclosed in patent CN218533080U.

[0003] However, during use, it was found that the existing internal thread processing equipment has a relatively simple structure, which is inconvenient for automatic feeding and unloading. Furthermore, when processing oblique flat internal threads, the tapping tool and the injector body assembly are in close contact, making it inconvenient to cool down the contact area between the tapping tool and the injector body assembly, resulting in poor practicality. Therefore, a tooling for processing oblique flat internal threads on the injector body assembly is needed to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tooling for machining the slanted internal thread of an injector body assembly. The injector body assembly is placed on a conveying mechanism and conveyed from right to left. Simultaneously, a cooling mechanism cools the injector body assembly. A clamping mechanism then clamps the injector body assembly and moves it to a tapping position. The injector body assembly is then machined with a slanted flat internal thread at the tapping position. Finally, the machined injector body assembly is discharged through the clamping mechanism, thereby improving the practicality of the equipment.

[0005] This utility model discloses a tooling for machining oblique flat internal threads on an injector body assembly, including a tapping mechanism; it also includes a conveying mechanism, a clamping mechanism, and a cooling mechanism, all of which are mounted on the tapping mechanism;

[0006] The conveying mechanism conveys the injector body assembly, the cooling mechanism cools the injector body assembly, the clamping mechanism limits the injector body assembly, and the tapping mechanism performs oblique flat internal thread processing on the injector body assembly.

[0007] The injector body assembly is placed on the conveying mechanism and transported from right to left. At the same time, the injector body assembly is cooled by the cooling mechanism. Then, the injector body assembly is clamped by the clamping mechanism and moved to the tapping position. The injector body assembly is then machined with a slanted flat internal thread through the tapping position. Finally, the machined injector body assembly is discharged by the clamping mechanism, thereby improving the practicality of the equipment.

[0008] Preferably, the tapping mechanism includes a worktable, a guide column, a slider, a support frame, a first hydraulic cylinder, a first motor, a rotary chuck, and a slanted flat internal thread tapping tool. The guide column and the first hydraulic cylinder are both mounted on the top of the worktable. The slider is slidably mounted on the guide column, and the support frame is fixedly mounted on the slider. The top end of the first hydraulic cylinder is connected to the bottom end of the slider. The first motor is mounted on the support frame, the rotary chuck is mounted on the output shaft of the first motor, and the slanted flat internal thread tapping tool is mounted on the rotary chuck. By retracting the first hydraulic cylinder, the slider slides downward along the guide column. By activating the first motor, the slanted flat internal thread tapping tool is driven to rotate, allowing the rotating slanted flat internal thread tapping tool to perform slanted flat internal thread machining on the injector body assembly, thereby improving the practicality of the equipment.

[0009] Preferably, the clamping mechanism includes a rotating shaft, a second motor, multiple sets of electric chucks, and multiple sets of springs. The worktable has an internal chamber and a pre-drilled opening at its top. The rotating shaft is rotatably mounted on the top of the worktable, and the second motor is fixedly mounted on the top of the worktable, with its output shaft connected to the front end of the rotating shaft. A rotating connecting line is located at the rear end of the rotating shaft. Multiple sets of electric chucks are mounted on the rotating shaft, and multiple sets of springs are respectively mounted in the middle of the multiple sets of electric chucks. Connecting the rotating connecting line to a power source and turning on the second motor drives the rotating shaft to rotate, moving one set of electric chucks directly below the rotating shaft. A set of injector body parts is conveyed to the middle of the bottom electric chuck by the conveying mechanism, and the spring at the bottom is compressed. Then the electric chuck clamps the injector body parts, and the second motor drives the rotating shaft to rotate, moving the injector body parts above the rotating shaft. The rotating slanted flat internal thread tapping tool performs slanted flat internal thread processing on the injector body parts. Then the rotating shaft continues to rotate, and the electric chuck releases the injector body parts. The elasticity of the spring ejects the injector body parts, completing the material discharge. Then the above steps are repeated to process other injector body parts, thereby improving the practicality of the equipment.

[0010] Preferably, the conveying mechanism includes multiple sets of drive shafts, a plate conveyor belt, multiple sets of support seats, a third motor, and a feeding mechanism. The multiple sets of drive shafts are rotatably mounted on the worktable. The plate conveyor belt is fitted onto the multiple sets of drive shafts and has multiple sets of drainage holes and multiple sets of first through holes. The multiple sets of support seats are mounted on the plate conveyor belt and each set of support seats has a second through hole, which overlaps with multiple sets of first through holes on the worktable. The third motor is fixedly mounted on the worktable, and its output shaft is connected to the front end of one set of drive shafts. The feeding mechanism is installed in the worktable. When the third motor is turned on, the plate conveyor belt is driven by the multiple sets of drive shafts. The operator then places the injector body assembly in the support seat, and the plate conveyor belt transports the injector body assembly to the top of the feeding mechanism. The feeding mechanism then pushes the injector body assembly into the electric chuck, thereby improving the practicality of the equipment.

[0011] Preferably, the feeding mechanism includes a second hydraulic cylinder, a feeding column, and a buffer pad. The second hydraulic cylinder is installed inside the workbench, and the buffer pad is installed on top of the second hydraulic cylinder via the feeding column. By extending the second hydraulic cylinder, the feeding column passes through the perforations of the plate conveyor belt and the support seat, pushing the injector body assembly in the support seat into the electric chuck. Then, the second hydraulic cylinder retracts, resetting the buffer pad, and the plate conveyor belt continues to run, conveying other injector body assemblies, thereby improving the practicality of the equipment.

[0012] Preferably, the cooling mechanism includes a cooling chamber, a thermoelectric cooling plate, a circulating pump, a water spray pipe, and multiple sets of nozzles. The cooling chamber and the circulating pump are both installed at the rear end of the workbench, with the drain outlet of the circulating pump communicating with the interior of the cooling chamber and the suction inlet of the circulating pump extending to the bottom of the workbench. The thermoelectric cooling plate is installed on the cooling chamber, with its cooling end extending into the interior of the cooling chamber and its heat dissipation end located on the outside of the cooling chamber, and a radiator provided on the heat dissipation end. One end of the water spray pipe communicates with the interior of the cooling chamber, and the other end extends into the interior of the workbench. Multiple sets of nozzles... All nozzles are installed on the water spray pipes, and multiple sets of nozzles are located above the plate conveyor belt. Coolant is poured into the workbench, the circulation pump is turned on, and the coolant in the workbench is discharged into the cooling tank, filling the cooling tank completely. The coolant is cooled by a semiconductor cooling plate, and then the cooled coolant enters the water spray pipe through the continuous operation of the circulation pump. The cooled coolant is then sprayed out by multiple sets of nozzles to cool the injector body assembly in multiple support seats, thereby reducing the temperature rise when the oblique flat internal thread tapping tool taps the injector body assembly, thus improving the practicality of the equipment.

[0013] Preferably, a material rack is provided at the left end of the workbench; the material rack supports the box body, allowing the box body to store the spring-loaded injector body assembly, thereby improving the practicality of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the injector body assembly is placed on the conveying mechanism, and the injector body assembly is conveyed from right to left by the conveying mechanism. At the same time, the injector body assembly is cooled by the cooling mechanism. Then, the injector body assembly is clamped by the clamping mechanism and moved to the tapping position. The injector body assembly is then machined with a slanted flat internal thread by the tapping position. Finally, the machined injector body assembly is discharged by the clamping mechanism, thereby improving the practicality of the equipment. Attached Figure Description
