Stop grinding device

Abstract

The invention relates to a stopper grinding device, comprising a base, an installation cavity is arranged in the middle of the base, an upper chamber and a lower chamber are formed in the middle of the installation cavity by isolation rings, a rotating motor is fixed on the top of the bottom plate through fixing screws, and the rotating motor The rotating shaft is set vertically, and the upper end surface of the base is located on both sides of the upper chamber, and two clamping devices are arranged symmetrically. The upper chamber is provided with a rotating tray and a fixed plate in sequence from bottom to top, and an end surface grinding round table is arranged in the middle of the upper end of the fixed plate. , the upper end of the end face grinding round table is provided with a bevel grinding round table, the lower end of the rotating tray is also provided with a ring of gear tooth structure, and the peripheral surface of the base is also provided with a stop bar. The stop bar of the present invention can cooperate with the tooth structure to realize the stop, so that the rotating tray will not rotate freely when loading and unloading the valve seat, which can avoid the situation of over-grinding caused by the stop not being timely, and ensures the sealing accuracy of the grinding surface and dimensional accuracy.

Description

technical field [0001] The invention relates to a grinding device, which belongs to the technical field of mechanical processing, and more specifically, the invention relates to a stop grinding device. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Valves generally include a valve body, a sealing cover, a valve seat, a valve core (disc) and a valve stem, which constitute a fluid-tight structure as a whole. Among them, the valve seat is a removable surface part in the valve, which ...
