Description

Quick disassembly body based on T type part

Technical Field

The utility model relates to an unmanned aerial vehicle field auxiliary assembly, in particular to quick disassembly body based on T type part for quick dismantlement of unmanned aerial vehicle mechanical arm portion structure.

Background

In the 21 st century science and technology era, the pace of science and technology is accelerated, the economic development is promoted to a greater extent, the unmanned aerial vehicle gradually develops to the civil industry from early military application after the development of nearly one century, the civil popularization is realized to a certain extent, the market of the unmanned aerial vehicle in China is in the stage of rapid growth, and the unmanned aerial vehicle enterprise, which is the first in the Xinjiang, pushes the development of the unmanned aerial vehicle to the wave. However, the current market for unmanned aerial vehicles is dominated by aerial photography and has fewer applications in industry, particularly in emergency rescue and aerial maintenance. In order to realize the application in the fields of rescue, air overhaul and the like, the application of the mechanical arm to the unmanned aerial vehicle has become an industry trend.

The current trade is gradually towards the mechanized assembly formula that realizes mechanical structure to developing, does not appear comparatively ripe to the module that devices such as unmanned aerial vehicle arm end effector support quick dismantlement or the instrument of carrying out relevant work yet, and mechanical structure's dismantlement often will lean on the manpower to dismantle manually. However, due to the complicated structure and assembly procedure of the end effector of the mechanical arm and other devices, the disassembly operation is complicated and the workload is large, which increases unnecessary workload and seriously affects the working efficiency of the application.

Disclosure of Invention

In order to overcome the defect of the prior art, the utility model aims to provide a quick disassembly body based on T type part has solved and has now changed too much complicacy to unmanned aerial vehicle arm end effector, increases unnecessary work load, improves work efficiency's problem.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

a quick disassembling mechanism based on T-shaped parts comprises a frame type base III, wherein a group of J-shaped parts II are symmetrically fixed in the middle of the base III through an A screw hole 6 by using a tooth bar, a columnar bulge 5 on each J-shaped part II is used for fixing one end of a spring 12, and the other end of each spring 12 is propped against the inner wall 7 of the base III; d screw hole 10 on base III connects apron IV, make whole detaching mechanism form a box body, be provided with notch 13 on the apron IV, notch 13 supplies T type part I to impress the box body, slotted hole 11 on the T type part I when barb 1 on the J type part II is connected and is pressed in, J type part II's last handle 3 is outside the box body, J type part II's inclined plane 4 touches with T type part I's lower inclined plane mutually, manipulator or other accessories are connected to T type part I's plane 2, other accessories on the unmanned aerial vehicle are connected to B screw hole 8 and C screw hole 9 on the base III.

The T-shaped part I can rotate clockwise around the central axis of the notch 13 within the range of 0-90 degrees.

J type part II can be around 6 axis clockwise rotations in A screw hole, and rotation range is 0-50 degrees.

Compared with the prior art, the beneficial effects of the utility model are that: based on T type part I carries out quick dismantlement to unmanned aerial vehicle arm end effector, simplifies and dismantles the step, greatly reduces the artifical work load of dismantling the arm of changing, improves application efficiency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a quick disassembly body based on T type part, includes frame type base III, at base III's middle part, utilizes the tooth stick symmetry to be fixed with a set of J type part II through A screw hole 6, and the equal one end of fixed spring 12 of the column arch 5 on every J type part II, the inner wall 7 of base III is all withstood to the other end of spring 12.

Referring to fig. 2, a D-screw hole 10 on the base III is connected with a cover plate IV, so that the whole dismounting mechanism forms a box body, a notch 13 is arranged on the cover plate IV, and the notch 13 is used for pressing the T-shaped part I into the box body and limiting the T-shaped part.

Referring to fig. 1 and 3, a barb 1 on a J-shaped part II is connected with a slotted hole 11 on a T-shaped part I when being pressed in, a plane 2 of the T-shaped part I is connected with a manipulator or other accessories, and an upper handle 3 of the J-shaped part II is arranged outside a box body and used for manually pressing the J-shaped part II; the inclined plane 4 of J type part II touches with T type part I's lower inclined plane 14 mutually, supports two J type parts II from top to bottom, treats that T type part rotation 90 back J type part goes up cylinder 5 fixed spring 12 and rebounds it, and barb 1 inserts the draw-in groove and need not manual the stirring of people on the T type part I. Other accessories on the unmanned aerial vehicle are connected to B screw hole 8 and C screw hole 9 on the base III.

Referring to fig. 4, the working principle of the present invention is:

when the installation, T type part I passes notch 13 on the apron IV, and downwards, inclined plane 14 and the contact of inclined plane 4 on the J type part II on the T type part I, promote J type part II and be partial to both sides, treat to press forward 90 when the bottom and rotate T type part I, because its body both ends and notch 13 edge offset, accomplish its spacing on forward direction of rotation. Meanwhile, the elliptic bottom of the T-shaped part I is fixed by the chassis III and the cover plate IV in the in-out direction, and the limiting of the T-shaped part I in the in-out direction is completed. The J-shaped element II is rebounded by the compressed spring 12, so that the barb 1 is inserted into the slotted hole 11 at the bottom of the T-shaped element, and the limiting of the barb in the reverse rotation direction is completed.

When dismantling, stir two J type part II for barb 1 loosens, reverse 90 rotation T type part I, J type part II is pushed to both sides once more this moment, vacates the rotation path, pulls out it again, makes the mechanical part of installation T type part I break away from, accomplishes quick dismantlement. At this point the J-shaped part II is sprung back by the spring 12 to await the next installation.
