Description

A kind of robot end's flange and assembly
Technical field
The present invention relates to robotic technology field more particularly to the end flanges and end method of a kind of industrial robot Blue assembly.
Background technique
The end flange of robot can be used for connecting various types of executing agencies, and executing agency needs to receive robot Electrically, air pressure etc. controls signal to execute corresponding control command.In the prior art, generally outside the robot cabling (such as from Robot arm draws cable or hangs lead-out wire cable from aerial) to transmit signal to executing agency, there are following for external cabling Disadvantage: 1) cause robot shape not simple and beautiful enough;2) External cable is easy to wind with robot each joint, both influences The normal operation of robot, and influence the normal transmission of signal.
Due to end flange small volume, inner space is more narrow, lacks internal cabling space, to from end flange Output pipe is drawn, general way is to increase the volume of end flange, but after the volume of end flange increases, will lead to it Flexibility reduces, and energy consumption increases.
Therefore, the technological progress for promotion industrial robot goes reality how under the premise of not increasing end flange volume Now the problem of output pipe is current urgent need to resolve is drawn from end flange.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of robot end's flange, and solution lacks in the prior art Weary the technical issues of being suitable for from the end flange of robot interior cabling;The present invention also provides robot end's flange is total At solution needs to increase end flange volume in the prior art come the technical issues of meeting internal cabling requirement.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions: a kind of robot end's flange, end End flanges have the outer end face for connecting executing agency, are equipped with inside end flange adjacent and parallel in the outer end face End plate, the inner end plate of the end flange are inner face away from the end face of outer end face;End flange side is equipped with connector mounting hole, Electrical connector or pipe joint are fixedly mounted on connector mounting hole, and are protruded into inside end flange from connector mounting hole.
A kind of robot end's flange assembly, including above-mentioned robot end's flange, the inner face of end flange passes through Adapter is connected with hollow reducer;Adapter center is equipped with the cable-through hole being connected to the hollow shaft of hollow reducer;End method Being equipped between blue inner face and adapter can be by the mistake on the space and adapter between adapter and end flange inner wall The passing channel that string holes is connected;One end of cable or pipeline enters to protrude into the hollow shaft of hollow reducer, stretches out from cable-through hole, And it is protruded into the space between adapter and end flange along the passing channel, and corresponding on end flange electrically connect Head or pipe joint connection.
Further, crossed beam trunking is provided on the inner face of the end flange, crossed beam trunking extends to interior from inner face edge End face center;The connector mounting hole is several, and including the axial line not inclined hole vertical with end flange axial line;It is described Electrical connector or pipe joint are connect with the connector mounting hole on end flange using screw fastening manner.
Further, cable or pipeline are coiled in adapter side, electrical connector or pipeline connect after passing channel stretching Head is connected in the coiling section of cable or pipeline.
Further, the adapter is equipped with towards the end face of end flange in concentric locating torsion sensor Stile or outer stile;Outer stile is arranged along adapter outer edge, and crossed beam trunking penetrates through outer stile, and torsion sensor is placed in outer stile and encloses At groove in, and torsion sensor lateral surface is bonded with outer stile medial surface;The side of interior stile cable-through hole along adapter Edge setting, torsion sensor center are equipped with the location hole for being inserted into interior stile, and interior stile lateral surface is bonded with location hole inner wall.
Compared with prior art, the invention has the following advantages:
1, accommodation space is provided for cable or pipeline in the hollow shaft of hollow reducer, the hollow shaft of hollow reducer is method again The rotation center that orchid moves ensures that cable or pipeline only occur inside hollow channel in flange movement from torsion in this way. The space between occupancy end flange and hollow reducer thus is avoided that accommodate cable or pipeline, to reduce end flange Volume, while also assuring the reliability of electrical connection.
2, hollow reducer is fixed together by adapter and end flange, and electrical connector or pipe joint are fixed on end In end flanges, when hollow reducer drives end flange and executing agency rotates, electrical connector or pipe joint are also with end End flanges rotate together, and the cable or pipeline between connector or pipe joint and executing agency are also with end flange It rotates together, to keep opposing stationary relative to end flange.Since cable only occurs to keep away from reversing inside hollow channel It is exempted from and has wound end flange, this ensure that the normal transmission of the normal operation of end flange and signal.
3, connector mounting hole includes inclined hole, and inclined hole, which can satisfy, not to be increased end flange volume and come that installation length is longer to be connect Head requirement, if lengthening joint is extended vertically into end flange by connector mounting hole, it require that end flange with it is hollow There is biggish clearance space among speed reducer, the volume for increasing end flange certainly will be required.Through-hole is set as inclined hole, then sufficiently The clearance space between end flange and hollow reducer is utilized.
4, electrical connector or pipe joint are connected in the coiling section of cable or pipeline, coiling section speed reducer and flange it Between gap, the cable or pipeline that when demounting flange coils can be straightened, convenient for the peace of flange, electrical connector and pipe joint Assembly and disassembly.The present invention makes full use of the clearance space between end flange and hollow reducer by way of coiling, realizes In the case where connecting same polylinker, the volume of end flange is not increased.
5, the stile on adapter plays positioning action to torsion sensor, ensure that adapter is same with torsion sensor The heart.
