TECHNICAL FIELD

[0001] The present application relates to the technical field of valve machining, in particular to a valve end face machining machine tool. BACKGROUND

[0002] With the development of society, as the core component of the fluid control system, the valve is widely used in many industrial fields such as petroleum, chemical industry, water conservancy, and power, and the machining precision of the end face directly determines the sealing performance and service life of the valve. The valve end face needs to be closely attached to the pipe flange or other components. If the flatness error, perpendicularity deviation or surface roughness of the end face exceeds the standard, it will cause fluid leakage, not only causing resource waste, but also possibly causing safety accidents.

[0003] However, the existing valve end face machining machine tool generally needs manual correction when clamping and fixing the valve. The main reason is that the structures of different types of valves are quite different, and the existing clamping mechanism is designed with fixed size and cannot adapt to valves of different specifications, resulting in problems such as the end face not being perpendicular to the machining tool and the center axis deviating from the machining reference line after the valve is placed on the machining table.

[0034] Then, control the external high-pressure gas supply equipment to input high-pressure gas into the gas distribution pipe one 906, and the high-pressure gas is evenly distributed to the three mounting cavities one 902 of the two T-shaped frames 901 through the gas outlet end of the gas distribution pipe one 906, and the high-pressure gas forms an outward thrust in the mounting cavity one 902, pushing the connecting rod 903 to slide outward along the inner wall of the mounting cavity one 902, and the connecting rod 903 synchronously drives the front end of the correction block 904 to extend out, and the three correction blocks 904 of the two T-shaped frames 901 correspond to different pipelines of the valve respectively, and apply uniform extrusion force from the left and right sides of the pipeline, so as to automatically adjust the valve to a vertical state with the bearing plate 1, if the valve initially exists inclination, a certain side correction block 904 will first contact the valve and apply a thrust, until the valve is balanced in each direction, and the position is accurately corrected.

[0035] Then, keep the gas supply state of the gas distribution pipe one 906, and at the same time, control the external gas supply equipment to input high-pressure gas into the gas distribution pipe two 911, and the high-pressure gas enters the gas guide cavity of the two mounting blocks 907 through the gas outlet end of the gas distribution pipe two 911, and the gas guide cavity evenly distributes the high-pressure gas to the plurality of mounting cavities two 908, and the high-pressure gas pushes the fixed column 909 to slide outward along the cavity wall in the mounting cavity two 908, and the plurality of fixed columns 909 of the two mounting blocks 907 synchronously extend out, and apply clamping force from the left and right outer walls of the valve, so as to firmly fix the valve on the slide table of the lead screw guide slide table three 8.

[0037] If there are rust, oil stains or impurities on the valve end face, the end face needs to be cleaned first. The valve is moved backward by the lead screw guide rail sliding table three 8, so that the end face to be processed moves to the cleaning disc 12 position.

[0038] Then, control the lead screw guide rail sliding table two 4 to drive the mounting frame 5 to slowly descend, so that the cutting edge of the milling cutter disc 603 gradually contacts the valve end face to be processed. The driving shaft one 602 drives the milling cutter disc 603 to rotate at high speed. The cutting edge on the edge of the milling cutter disc 603 mills the valve end face.
