Valve plate valve opening trimming device

Abstract

The invention belongs to the technical field of the manufacturing of a valve, and in particular relates to a valve plate valve opening trimming device. The valve plate valve opening trimming device comprises a worktable, two trimming mechanisms and a tightening mechanism, wherein the trimming mechanisms and the tightening mechanism are respectively fixed on the worktable, the two trimming mechanisms are respectively fixed on the worktable, the tightening mechanism is arranged between the two trimming mechanisms, each trimming mechanism mainly consists of a first motor, a second motor, a transmission case, a reduction box and milling cutters, the first motor is arranged on the upper part of the reduction box, the output end of the first motor is connected with the input end of the reduction box through the transmission case, a slide plate is fixedly arranged on the bottom of the reduction box, the slide plate is in sliding fit with a slide rail which is fixed on the worktable, the bottom of the slide plate is provided with a lead screw sleeve, and the lead screw sleeve is matched with a lead screw. The two milling cutters can be used for simultaneously shaping a left hole and a right hole of a valve plate in the left direction and the right direction, the milling cutters can be replaced only by releasing a triangular chuck after the shaping, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of valve manufacture, and in particular relates to a device for trimming valve holes on a valve plate. Background technique [0002] The valve is mainly composed of a valve body, a valve plate and a valve seat. The valve seat is installed in the valve body, and the valve plate is installed in the valve seat. The valve plate has some burrs on the valve hole used to install the valve stem after forming. If it is not removed, it will affect the installation of the valve stem. In the prior art, the valve hole on the valve plate is repaired by fixing the valve plate first, and then The valve hole is drilled and milled with a milling cutter, and the other surface is processed after cleaning one surface. This working method is slow and needs to fix the valve plate twice. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, a...

The valve plate has some burrs on the valve hole used to install the valve stem after forming. If it is not removed, it will affect the installation of the valve stem. In the prior art, the valve hole on the valve plate is repaired by fixing the valve plate first, and then The valve hole is drilled and milled with a milling cutter, and after one surface is cleaned, the other surface is processed. This kind of working method is slow, and the valve plate needs to be fixed twice.
