Embodiment Construction

[0028] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0029] Such as Figure 1-8 As shown, a device for machining the circumferential oblique hole of the nozzle nut of an aero-engine includes a base 1, a V-shaped support 2, a drilling mold 3 and a compression nut 4. The upper surface of the base 1 is an inclined plane, and the V-shaped support 2. It is fixedly installed on the upper surface of the base 1; the V-shaped support 2 has a V-shaped groove, and the direction of the notch is upward along the slope of the base 1. The drilling template 3 is placed on the base 1, and one side of the drilling template 3 is embedded in the V-shaped In the V-shaped groove of the support 2; the drilling mold 3 is cylindrical, and an inner cavity 33 suitable for the part 10 to be processed is provided inside, and a circle is opened on the upper surface of the drilling mold 3 corresponding to the posi...

Abstract

A device for machining a circumferential inclined hole of a nozzle nut of an aero-engine comprises a base, a V-shaped support, a drill jig and a compression nut. The upper surface of the base is an inclined plane, and the V-shaped support is fixedly installed on the upper surface of the base; and during installation, a to-be-machined part is placed in an inner cavity, then the compression nut is screwed into the inner cavity from the bottom of the inner cavity, and the to-be-machined part tightly abuts against the interior of the inner cavity. Through the implementation of the device, the portion wherein the inclined hole needs to be machined is changed to be subjected to straight hole machining of a conventional machine tool, the situation that a five-axis machining center needs to be adopted for machining is avoided through the device, part machining can be achieved through a common drilling machine and a bench drill, the part machining cost is reduced, and meanwhile, the frequent alignment and tool setting time for machining a thread locking hole is saved; and the first part does not need to be adjusted after being debugged and machined to be qualified, clamping is convenient and rapid, the production efficiency of the part is improved, the production cost of the part is reduced, and the production benefits of enterprises are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a device for machining an oblique hole in the circumferential direction of an aeroengine nozzle nut. Background technique [0002] Such as Figure 9-11 As shown, a circle of inclined holes is arranged on the inclined surface of the nozzle nut used for aero-engines during design. The processing parameters of the inclined holes are mainly composed of hole diameter, angle and circumferential positioning dimensions. A circle of oblique holes in the cloth needs to be processed in a five-axis machining center by means of alignment and tool setting. This method requires high equipment, the parts are large in batches, high in quantity, and the equipment takes a long time, resulting in high cost of parts and cost-effectiveness. Difference. Therefore, there is an urgent need to provide a device specially used for machining the oblique hole, so as to realize the m...
