Microporous extrusion grinding machine tool

Abstract

The invention discloses a microporous extrusion grinding machine tool. The microporous extrusion grinding machine tool comprises a frame, an abrasive barrel, a suction system, a filtering system, an oil switching system and a clamp assembly, wherein the frame comprises a power part and an operating part; one side of the power part is provided with a door; one side of the operating part is providedwith an opening; the suction system comprises a large servo electric cylinder, a suction cylinder and a solenoid valve VI; the large servo electric cylinder is installed in the power part; the top end portion of a piston rod of the large servo electric cylinder is fixedly connected to a piston; the suction cylinder is fixedly connected to the top of the large servo electric cylinder; a sealing member is arranged between the suction cylinder and the large servo electric cylinder; the piston of the end portion of the large servo electric cylinder is slidably connected to the inner wall of the suction cylinder; the solenoid valve VI is fixedly connected to the suction cylinder; and the solenoid valve VI is connected to an inner cavity of the suction cylinder through a pipe. BY means of the microporous extrusion grinding machine tool, two micro holes can be machined on one device at the same time, and with no need of changing multiple devices, so that the time and labor are saved, and thework efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of micropore processing equipment, in particular to a micropore extrusion grinding machine tool. Background technique [0002] The common rail injector is a key component in the common rail system of the diesel engine, and the key technology that the common rail injector needs to solve is how to control and accurately control the fuel injection quantity, so that the spray characteristics of the common rail injector conform to the combustion system of the diesel engine. Require. In this process, the valve sleeve in the common rail injector plays an important role. [0003] Such as figure 1 As shown, the two ends of the valve sleeve 60 are respectively a valve stem 61 and a baffle, and its overall longitudinal section is in the shape of a "T". The bottom end of the valve rod 61 is provided with a middle hole 65 , the side of the valve rod 61 is provided with a Z hole 64 passing through the middle hole 65 , ...

Problems solved by technology

[0005] However, the traditional micro-hole extrusion grinding machine can only process a single micro-hole at a time, and there are two micro-holes on the valve sleeve. When processing the valve sleeve, it is necessary to use one device to process the A hole, and then change another device. Processing the Z hole is time-consuming and labor-intensive, and the work efficiency is extremely low
