Abstract

The invention relates to a clamping tool for grinding the end surface of a gland sealing ring of a steam turbine, comprising a bending plate, wherein a U-shaped pressing plate is horizontally fixed at one side on the plane of the bending plate by a rotary handle I; a pressing head is fixed on the lower part of the closed end of the U-shaped pressing plate by a wing-shaped screw; a guide groove vertical to the U-shaped pressing plate is arranged outside the closed end of the U-shaped pressing plate on the bending plate; a supporting block and a rotary supporting block are arranged in the guide groove in sequence from top to bottom; and an inclined block is arranged at one side on the plane of the bending plate opposite to the U-shaped pressing plate. The clamping tool has the characteristics that the clamping is convenient, gland steam rings with different diameters can be ground, the centrality of the end surface of the gland steam ring can be guaranteed, the grinding amount can be mastered accurately and the like.

Description

[0001] technical field [0002] The invention relates to a clamping tool, in particular to a clamping tool for grinding the end face of a steam turbine seal ring. Background technique [0003] At present, the end face of the steam seal ring needs to be precisely ground during the machining process of the steam turbine to ensure that the upper and lower half seal rings maintain a certain gap during installation, and it is necessary to ensure that the end face of the seal ring is centered during grinding. Some domestic manufacturers grind the steam seal ring mainly by clamping the steam seal ring on the vise for manual grinding and de-measurement. Although it is simple and easy to operate, it is difficult to ensure the centripetality of the end face of the seal ring when the amount of grinding is slightly large, and it is difficult to accurately grasp the amount of grinding. Contents of the invention [0004] The purpose of the present invention is to overcome the above-men...
