Description
Technical field
The structure-design technique field of robot is the utility model is related to, espespecially one kind changes rifle disk.
Background technology
Robot tool exchanging device is mainly dimeric, is divided into tool side and main body side.Main body side is general
Robot end is fixed on, tool side connection uses instrument, and main body side changes different uses by clamping and release tool side
Instrument.Generally in actual use, a main body side can correspond to two sets or cover tool side to reach the mesh of replacing instrument more
's.
Instrument exchanging decice clamping and release at present are realized steel ball clamping and release using piston rod and retaining ring, are such as schemed
1st, shown in 2, main body side is mainly by main board 10, gear pad 11, piston (piston cap 12 and piston rod 13), flange 14 and steel ball
30 compositions, tool side is made up of tool palette 20 and retaining ring 21.Main board 10, gear pad 11, piston cap 12 and flange
14 constitute two closed cavitys 15 and 16, and tool palette 20 and retaining ring 21 constitute the locking mechanism of tool side.
As shown in Figure 1, 2, there is a series of steel ball contact area on piston rod 13, when main body side and tool side do not clamp,
Steel ball 30 is usually remained in these contact areas.Steel ball contact area on piston rod 13 includes three kinds of contact surfaces：It can not press from both sides
Tight contact surface, safety anti-releasing contact surface and clamped contact face.These three contact surfaces mainly have two functions：Clamping function and anti-
De- function.
When main body side needs to couple with tool side, air pressure enters out of cavity 15, promotes piston from released position to folder
Tight position is (as shown in Figure 2) mobile, steel ball process can not clamp successively contact surface and safety anti-releasing contact surface, is clamped when reaching
During contact surface, steel ball contacts with the locking mechanism of tool side simultaneously, completes the clamping of main body side and tool side.When air pressure is not enough to
Supporting piston or air pressure are temporarily interrupted or when prolonged stoppages, and safety anti-releasing contact surface is contacted with steel ball and help agent side
Keep clamping with tool side.Safety anti-releasing contact surface it is temporary transient prevent piston and its contact surface to be directly shed to from clamped position
Released position.
The safety anti-releasing surface of piston rod is a cylindrical groove, axis of the groove curved surface parallel to piston rod.
Therefore, the axial force for making piston rod from clamped position to released position will not be produced.But in some cases, such as by strong
When violent shock moves, impacts either other external force, piston may be moved to released position from anticreep contact surface.Also, existing
Instrument exchanging decice in, its released position and clamped position are very close, this also cause piston be easy to from clamped position move
Move to released position.
Therefore, the applicant, which is directed to providing, a kind of new changes rifle disk.
