Throat liner machining equipment

Abstract

The invention relates to throat liner machining equipment. The throat liner machining equipment comprises a numerically-controlled machine tool, wherein the numerically-controlled machine tool comprises a saddle; a backing plate is arranged on the upper surface of the saddle; a first fixture and a second fixture are connected and arranged on the backing plate; the second fixture comprises a second fixed support seat; a rotating table is rotationally connected to one side facing the first fixture, of the second fixed support seat, and a clamping element is arranged on the rotating table; the first fixture comprises a first fixed support seat; an ejection rod capable of stretching out towards the direction of the second fixture to eject the end surface of one end departing from the second fixture, of a workpiece, is arranged on the first fixed support seat; during machining, one end of the workpiece is fixed on the clamping element, and the other end of the workpiece is tightly ejected through the ejection rod, thus vibration between a spindle of the numerically-controlled machine tool and the workpiece is reduced, and clamping damages to a drilling part of the workpiece are also avoided; and by using the numerically-controlled machine tool, accuracy during machining is ensured, in addition, the workpiece is driven to transversally move and rotate through the transversal movement carried out through the backing plate and the rotation of the rotating table, and accuracy control is facilitated, thus the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of throat lining processing, and more specifically, relates to a throat lining processing equipment. Background technique [0002] Throat lining is the lining material of the throat of the solid rocket motor nozzle. There are multiple through holes inside it. When the rocket is launched, the gas is ejected through the throat of the nozzle to generate thrust. It has very high requirements; most of the throat lining materials currently used are carbon rods. During processing, due to the need to process more through holes on the carbon rods, the carbon rods need to be turned over manually. The production efficiency of the conventional clamping method is low. It is easy to damage the outer surface of the carbon rod, and at the same time, the main shaft vibrates greatly during drilling, which may easily cause the drill bit to break and cause the product to be scrapped.
