Description
Technical Field
The utility model relates to a coupling processing technology field specifically is a processingequipment of special pipe joint multi-angle insurance hole for aviation.
Background
A large number of special-shaped pipeline structures exist in the aerospace engine, and the special-shaped pipe joint is a connecting tool between pipelines and is a connecting point which can be disassembled and assembled between an original piece and the pipelines, and plays an indispensable important role in the special-shaped pipeline structures. In order to prevent the connection part of the special-shaped pipe joint from loosening in the working process, most aviation special-shaped pipe joints are structurally provided with a fuse hole, and a fuse is bound on a workpiece after passing through the fuse hole and is used for locking and loosening prevention between the connection parts of the special-shaped pipe joints.
The existing special pipe joints have various forms, including a special pipe joint shown in fig. 1 and 2, which comprises a left joint, a right joint and a third joint positioned between the left joint and the right joint; the safety hole is only arranged on the left joint or the right joint in general, the included angle between the front projection of the safety hole and the vertical direction is an angle A, the included angle between the safety hole and the upper edge of the twisted surface of the special-shaped pipe joint plate is an angle B at the section A-A, the processing difficulty of the safety hole is that the relative position of the safety hole and the special-shaped pipe joint must meet the regulations of the angle A and the angle B at the same time, and the specific angle of the angle A and the angle B is determined according to the specific application scene of the special-shaped pipe joint.
At present, most of aviation enterprises in China generally adopt the following processing methods in the processing process of the special-shaped pipe joint safety hole: as shown in fig. 3, the special-shaped pipe joint is placed on the inclined top surface of the base of the processing device, the section of the pipe orifice of the left joint (or the right joint) of the pipe joint is positioned with the upper surface of the screwing surface of the plate by three positioning pins a, and the special-shaped pipe joint is pressed by a pressing block b parallel to the inclined top surface of the base, so that the special-shaped pipe joint is fixed on the traditional processing device; then the processing device is placed on a bench drill, and the drill is assisted by a traditional drill jig to position so as to drill the special-shaped pipe joint.
The above conventional processing method has the following drawbacks:
1. the positioning mode is three positioning pins, the contact surface of the positioning pins and the special-shaped pipe joint is limited, the special-shaped pipe joint is easy to be obliquely installed during clamping, and the angle and the size of a safety hole of the special-shaped pipe joint are out of tolerance due to unreliable positioning;
2. because the position of the positioning pin is fixed, when the special-shaped pipe joints are switched, if the sizes of the special-shaped pipe joints are different, the positioning pin is easy to interfere with the clamping of the special-shaped pipe joints, and the clamp is not strong in universality;
3. the drill jig fixes the hole diameter, the wall thickness and the like of the part, so that the universality is not strong.
Therefore, in order to ensure that the special-shaped pipe joints with various sizes can be accurately machined on one set of machining device, the clamp which can be conveniently assembled and disassembled and can flexibly adjust parts so as to be suitable for the special-shaped pipe joint safety hole drilling with various sizes is particularly important.
SUMMERY OF THE UTILITY MODEL
