Machining method of high-precision sealing hole

Abstract

The invention belongs to the field of valve machining, particularly relates to a machining method of a high-precision sealing hole. The following scheme is now put forward aiming at the problems that an existing sealing hole machining method is single and rough, the use requirement is difficult to meet, sealing holes with different sizes cannot be machined on the same machining line, and the machining efficiency is low. The method comprises the steps that S1, a valve element is placed on a machining table, a clamp is used for fixing the position of the valve element, a perforating machine is erected on a Y-axis guide rail, the Y-axis guide rail is laid on an X-axis guide rail, and position adjustment of the perforating machine can be achieved. According to the sealing hole machining method, different use requirements can be met, sealing holes of different sizes can be machined on the same machining line, the machining efficiency is high, dust and impurities can be restrained and collected in the punching and grinding process, and the situation that the machining environment is affected by dust and chippings in the machining process is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of valve processing, in particular to a processing method for a high-precision sealing hole. Background technique [0002] The three-way valve is suitable for automobiles, instrumentation and other industries. It is used to control the flow direction of the medium in the pipeline. The pneumatic three-way valve is remade from an ordinary three-way ball valve. The valve body at the outlet, the valve core with a through hole and rotatable in the valve body, the valve stem fixedly connected with the valve core, the gear fixedly connected with the valve stem, the rack meshed with the gear, and the When the three-way ball valve is in the normal position, the sealing hole of the valve core is connected with the inlet and an outlet of the valve body, and when the flow direction of the medium in the pipeline needs to be switched, the rack is driven by the cylinder. The drive gear rotates at a certain angle, thereby ...

[0002] The three-way valve is suitable for automobiles, instrumentation and other industries. It is used to control the flow direction of the medium in the pipeline. The pneumatic three-way valve is remade from an ordinary three-way ball valve. The valve body at the outlet, the valve core with a through hole and rotatable in the valve body, the valve stem fixedly connected with the valve core, the gear fixedly connected with the valve stem, the rack meshed with the gear, and the When the three-way ball valve is in the normal position, the sealing hole of the valve core is connected with the inlet and an outlet of the valve body, and when the flow direction of the medium in the pipeline needs to be switched, the rack is driven by the cylinder. The drive gear rotates at a certain angle, thereby driving the rotation of the valve stem fixedly connected with the gear, and then making the valve core fixedly connected with the valve stem rotate at a certain angle to close the original outlet and make the valve core seal the hole It becomes connected with the inlet of the valve body and another outlet. However, the existing sealing hole processing method is single and rough, which is difficult to meet the needs of use, and different sealing hole sizes cannot be processed on the same processing line, and the processing efficiency is low.
