Embodiment 1

[0080] The present embodiment provides a kind of device that is used for aircraft skin drilling, and it comprises:

[0081] A large arm part with multiple degrees of freedom, a support connection seat, a small arm part with multiple degrees of freedom and a suction cup part;

[0082] The end of the big arm part is fixed on the first side of the support connection base, and the small arm part and the suction cup part are independently installed on the second side of the support connection base;

[0083] The big arm part can drive the support connection seat to move to the working area of ​​the aircraft skin, and the support connection seat is fixed relative to the skin by means of the suction cup of the suction cup part. Drill holes at multiple locations in the work area.

[0084] The supporting connection seat in this embodiment may be a plate-like structure.

[0085] For example, the suction cup part may include: at least one set of suction cup assemblies; figure 1 Shown a...

Embodiment 2

[0091] Such as figure 1 As shown, the boom part in this embodiment has five degrees of freedom. Specifically, the boom part includes a base (2), a rotating joint one (3), a screw drive one (4), a parallelogram mechanism one ( 5), two rotating joints (6), two screw drives (7), two parallelogram mechanisms (8), three rotating joints (9), a total of 5 degrees of freedom, the arm part can move on the guide rail (1) .

[0092] figure 1 Parallelogram mechanism one (5) in the structure is connected with the base (2) through the rotary joint one (3), and can perform relative rotation to form the first degree of freedom;

[0093] Lead screw drive 1 (4) is located at the diagonal of parallelogram mechanism 1 (5), and can perform stretching motion to make parallelogram mechanism 1 (5) change shape, forming a second degree of freedom;

[0094] The first parallelogram mechanism (5) is connected with the second parallelogram mechanism (8) through the second rotating joint (6), and can pe...

Abstract

The invention provides a device used for aircraft skin drilling. The device comprises a large arm part with multiple degrees of freedom, a supporting connecting base, a small arm part with multiple degrees of freedom and a sucking disc part, wherein the large arm part can slide along a guide rail; the tail end of the large arm part is fixedly arranged on the first side surface of the supporting connecting base; the small arm part and the sucking disc part are independently mounted on the second side surface of the supporting connecting base; the large arm part can drive the supporting connecting base to move to a working region of aircraft skin; the supporting connecting base is fixed relative to the skin by virtue of a sucking disc of the sucking disc part; and the small arm part drills on a plurality of positions of the working region. Compared with existing skin drilling equipment, the device provided by the invention is more suitable for a complex surface of aircraft skin, has greater drilling space and greater flexibility.

Description

technical field [0001] The invention relates to the field of industrial manipulators, in particular to a device for drilling aircraft skins. Background technique [0002] Manipulators are devices that can replace humans to complete various operating functions. With the development of science and technology, manipulators are used in various fields, especially in the drilling of aircraft skins; the traditional way of making holes is manual pneumatic drilling, and human factors are inevitable. The precision of the hole is not high, and the quality of the hole is greatly improved by using a manipulator instead of manual work. [0003] The aircraft skin drilling devices in the prior art are all used. The industrial manipulator loads the end effector to drill holes. The stiffness of the industrial manipulator itself is relatively poor, and the working space in this state is relatively small. Flexible, larger working range aircraft skin drilling device.
