Valve plane sealing face grinding tool

Abstract

The invention relates to the field of valve techniques and provides a valve plane sealing face grinding tool. The valve plane sealing face grinding tool comprises a main shell (1), a spring (2), an eccentric sleeve (3), an eccentric shaft (9) and a grinding disc assembly body (21), the main shell (1) is mounted on a machine tool main shaft hole, and a machine tool main shaft is utilized to rotate so as to drive the whole grinding tool to make rotating movement. By controlling the compression amount of the spring (2), acting force of the spring (2) acts on grinding workpieces, and control of normal force of grinding of the grinding head assembly body (21) over the workpieces is achieved. By adoption of the double-eccentric structure of the eccentric shaft (9) and the eccentric sleeve (3), adjustment of the eccentric volume of the grinding disc assembly body is achieved. Through circular conical surface design of an adjustable disc (12) in the grinding disc assembly body (21), the effect that the grinding disc assembly body (21) has the universal adjusting function in the grinding process is achieved. By changing the compression amount of the spring (2), adjusting the eccentric volume of the grinding disc assembly body (21) or replacing grinding heads of other sizes, the valve plane sealing face grinding tool can be suitable for grinding over the diversified grinding workpieces. The valve plane sealing face grinding tool has the beneficial effects that universality is high, the grinding time is saved, and the grinding efficiency and quality are improved.

Description

technical field [0001] The invention relates to a process device for grinding the flat sealing surface of a valve, which is especially suitable for grinding different types of valves and valve sealing surfaces of different sizes and specifications. Background technique [0002] At present, most of the grinding of the flat sealing surface of the valve is manual grinding, and some simple manual grinding tools can meet the requirements of the valve. However, the grinding efficiency is low, and people with different experience will grind planes of different quality, and the qualified rate cannot be guaranteed, resulting in a relatively large difference in the thickness of each valve sealing surface. Manual grinding and simple grinding tools cannot accurately control the grinding pressure, the diameter of the grinding disc assembly, and the grinding quality cannot be guaranteed.

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the inability of the existing grinding tools to adjust the grinding pressure and the lack of the diameter of the grinding disc assembly, the invention provides a grinding tool, which can not only adjust the pressure when the sealing surface is ground, but also conveniently adjust the assembly of the grinding disc. The effect size of the body diameter, and accurately record the data value of the downforce and the eccentric diameter of the grinding disc assembly
