Abstract

The invention discloses a machine grinding disc tool. The tool comprises a spindle connector used for mechanical connection of a machine tool spindle, a compressing structure used for mechanical connection of the spindle connector and a grinding disc used for mechanical connection of the compressing structure. The compressing structure comprises an intermediate plate. An axial cavity is formed in the middle of the intermediate plate. One end of the cavity is opened in the axial direction of the intermediate plate. The opening position is movably connected with a spring sleeve. A first spring is arranged in the cavity in the axial direction of the intermediate plate. The first spring abuts against the spring sleeve in the axial direction of the intermediate plate. The first spring stretches to apply pressure to the spring sleeve, and the end, facing the grinding disc, of the spring sleeve is connected with a ball journal. A ball journal cavity matched with the ball journal in shape and size is formed in the top of the grinding disc. The ball journal is movably arranged in the ball journal cavity. According to the machine grinding disc tool, the flexible grinding design principle is adopted; and through the core structure of the ball journal and the spring and the structural design of a movable butting shaft in the circumferential direction, the end face of the grinding disc can be perfectly attached to the surface of a workpiece in the machining process, and grinding is more uniform and consistent.

Description

technical field

[0001] The invention relates to a processing tool, in particular to a grinding disc tool for a machine. Background technique

[0002] The high-temperature stack roof is an independent component of the pressure vessel. In terms of machining, there are many machining contents and high precision requirements. Its final machining must be carried out after the final heat treatment, and the processing includes the sealing surface of the top cover, 8 nozzles of the material radiation supervision tube, 6 nozzles of the absorbing ball drive shell, 1 nozzle of the control rod shell, and 3 feeding nozzles , 1 manhole seat, 76 main bolt holes, 4 pin holes. Among them, the machining accuracy of the sealing surface of the control rod nozzle flange is extremely high, which is a key point in the machining of the top cover.

[0003] The flange surface of the control rod shell nozzle is circular, and the overall surfacing material is stainless steel. The flange size is Ο†3662...
