Description

Technical Field

[0001] This invention relates to a dual-drive top milling device for a micro control valve core for a common rail injector, belonging to the technical field of common rail injectors. Background Technology

[0002] A common rail injector is a key component in the fuel injection system of an internal combustion engine. It achieves a stable fuel pressure supply and precisely controls injection timing and quantity through high-pressure common rail technology. This device drives the injection process via a solenoid valve, solving the consistency problem of traditional injectors under pressure fluctuations.

[0003] In order to achieve the highest response speed with the lowest energy consumption within an extremely limited space, thereby precisely controlling the enormous fuel pressure and ultimately meeting the demands of modern diesel engines for ultra-high pressure, high frequency, and high precision fuel injection, the control valve core inside the common rail injector is developing towards miniaturization, which also brings great difficulties to the manufacturing process.

[0004] To address this, a dual-drive top milling device with a micro control valve core for common rail injectors is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a dual-drive top milling device for a micro control valve core for a common rail injector, to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of the present invention is implemented as follows: A dual-drive top-grinding device for a micro control valve core of a common rail injector includes a processing table, a rotating table fixedly connected to the top of the processing table, a fixed chuck movably connected to the right side of the rotating table, a placement slot provided inside the processing table, a moving mechanism provided inside the placement slot, the moving mechanism including a moving plate, a screw and a rotating motor, the bottom of the rotating motor fixedly connected to the inside of the placement slot, the front side of the screw fixedly connected to the output end of the rotating motor, the rear side of the screw movably connected to the inside of the placement slot, and the internal thread of the moving plate connected to the surface of the screw.

[0007] More preferably, the surface of the processing table is provided with a sliding groove, and the surface of the moving plate is movably connected to the interior of the sliding groove.

[0008] More preferably, a protective plate is fixedly connected to the top of the processing table, a connecting plate is movably connected inside the protective plate, and a water spray pipe is fixedly connected inside the processing table.

[0009] More preferably, the protective plate has a connecting groove inside, and the surface of the connecting plate is movably connected to the inside of the connecting groove.

[0010] More preferably, a handle is fixedly connected to the front side of the connecting plate, and an observation window is provided on the front side of the connecting plate.

[0011] More preferably, a rotary motor is fixedly connected to the front side of the movable plate, and a grinding disc is movably connected to the output end of the rotary motor.

[0012] More preferably, a fixing rod is movably connected to the top of the grinding disc, and the bottom of the fixing rod extends through to the bottom of the grinding disc.

[0013] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0014] I. This invention utilizes a moving mechanism. When adjusting the grinding position of a part, a rotating motor drives a screw to rotate, which in turn moves a moving plate back and forth. This allows workers to easily adjust the grinding position and precisely control the grinding accuracy of the part. A sliding groove ensures the moving plate follows a predetermined path, preventing it from exceeding its travel range and damaging the equipment. A protective plate isolates the part and protects workers by pulling the connecting plate during equipment use.

[0015] Second, this invention uses a connecting groove, so that when the connecting plate moves, it moves according to the movement trajectory provided by the connecting groove, which makes it convenient for workers to pull and use the connecting plate. By setting a handle and an observation window, workers can observe through the observation window during use, which makes it convenient to check the work progress in a timely manner. By setting a rotary motor and a grinding disc, the rotary motor drives the grinding disc to rotate, and the surface of the grinding disc grinds the surface of the parts, which makes it convenient for workers to process.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-3 As shown, this embodiment of the invention provides a dual-drive top-grinding device for a micro control valve core of a common rail injector, including a processing table 1, a rotating table 2 fixedly connected to the top of the processing table 1, a fixed chuck 3 movably connected to the right side of the rotating table 2, a placement groove 4 opened inside the processing table 1, a moving mechanism 5 arranged inside the placement groove 4, the moving mechanism 5 including a moving plate 501, a screw 502 and a rotating motor 503, the bottom of the rotating motor 503 fixedly connected to the inside of the placement groove 4, the front side of the screw 502 fixedly connected to the output end of the rotating motor 503, the rear side of the screw 502 movably connected to the inside of the placement groove 4, the inside of the moving plate 501 threadedly connected to the surface of the screw 502, a sliding groove 6 opened on the surface of the processing table 1, the surface of the moving plate 501 movably connected to the inside of the sliding groove 6, a protective plate 7 fixedly connected to the top of the processing table 1, a connecting plate 15 movably connected inside the protective plate 7, and a water spray pipe 8 fixedly connected inside the processing table 1.

[0028] When adjusting the grinding position of the parts using the moving mechanism 5, the rotating motor 503 drives the screw 502 to rotate, and the screw 502 drives the moving plate 501 to move back and forth, making it convenient for the staff to adjust the grinding position and accurately control the grinding precision of the parts. The sliding groove 6 allows the moving plate 501 to move along the trajectory provided by the sliding groove 6, preventing the moving plate 501 from exceeding its stroke and causing damage to the equipment. The protective plate 7 isolates the parts and protects the staff by pulling the connecting plate 15 when using the equipment.

[0029] Example 2

[0030] like Figure 4-5 As shown, in one embodiment, the protective plate 7 has a connecting groove 9 inside, the surface of the connecting plate 15 is movably connected to the inside of the connecting groove 9, the front side of the connecting plate 15 is fixedly connected to a handle 10, the front side of the connecting plate 15 has an observation window 11, the front side of the connecting plate 15 is fixedly connected to a rotary motor 12, the output end of the rotary motor 12 is movably connected to a grinding disc 13, the top of the grinding disc 13 is movably connected to a fixing rod 14, and the bottom of the fixing rod 14 extends through to the bottom of the grinding disc 13.

[0031] The connecting plate 15 moves along the trajectory provided by the connecting groove 9, making it easy for workers to pull and use the connecting plate 15. The handle 10 and the observation window 11 allow workers to observe the work progress in a timely manner. The rotary motor 12 drives the grinding disc 13 to rotate, and the surface of the grinding disc 13 polishes the surface of the parts, making it easy for workers to process.

[0032] In operation, the present invention works as follows: First, the parts are fixed by the fixed chuck 3. The connecting plate 15 is pulled to the left, and the connecting plate 15 is inserted into the connecting groove 9 when it moves to the left. After that, the rotary motor 12 is started, and the rotary motor 12 drives the grinding disc 13 to rotate. During the rotation of the grinding disc 13, the rotary motor 503 is started, and the rotary motor 503 drives the screw 502 to rotate. The screw 502 drives the moving plate 501 to move forward, so that the grinding disc 13 contacts the surface of the parts for grinding. When the operator replaces the grinding disc 13, the fixed rod 14 is pulled upward to disengage the fixed rod 14 from the interior of the grinding disc 13. At this time, the grinding disc 13 can be disassembled and replaced.

[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
