The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
The utility model mechanical arm, comprise the base that series connection is integrated successively, shoulder joint part, elbow joint part and arm gripping portion, also be included as the power set of the power that the each several part of described mechanical arm provides, wherein said base is provided with universal wheel, described arm gripping portion is provided with LED lamp and camera, described arm grabbing device comprises a steering wheel, the gear of described servo driving, two crawl finger structures that described gear connects, and connect two spring assemblies that capture finger structures.
The present embodiment mechanical arm, comprise the base 1 that series connection is integrated successively, shoulder joint part 2, elbow joint part 3 and arm gripping portion 4, also be included as the power set of the power that the each several part of described mechanical arm provides, wherein said base is provided with universal wheel (not shown), described arm gripping portion is provided with LED lamp and camera, described arm grabbing device comprises a steering wheel 41, the gear 42 of described servo driving, two crawl finger structures 43 that described gear connects, and connect two spring assemblies 44 that capture finger structures.Described camera is that described arm grabbing device is monitored in real time when carrying out operation, the standby lighting when light that described LED lamp can be used for operating environment is bright not.
Further, the hydraulic motor of the power set of described base for driving by hydraulic pump, and control turning to of described base and start and stop by three-dimensional four way solenoid valve.
Further, described shoulder joint drives by hydraulic cylinder.
Further, elbow joint part can realize the rotation within the scope of positive and negative 45 degree, the both sides of described elbow joint are provided with elbow joint drive unit, described drive unit comprises power section and control section, wherein said power section is the linear motion device that is arranged on elbow joint both sides, comprises a dc motor (not shown), and described dc motor is by worm screw 21 and worm gear 22, the line box 23 that described worm gear connects, the circuit 24 in described line box is connected with described elbow joint; Fast control section comprises steering wheel 51, is arranged on two circular discs structures 52,53 and gear 54 on steering wheel central shaft, and the potentiometer 55 of described gear and motor is connected.
When mechanical arm operation, steering wheel signal end is received signal, relay normally open contact in power supply of dc motor control circuit is closed, power supply of dc motor is connected, two dc motor electric currents flow to contrary, to adapt to the auto-lock function of worm and gear, steering wheel receives the angle that control signal turns to appointment, drive central shaft to rotate simultaneously, circular discs structure circular discs structure and gear are installed on central shaft, they rotate together, gear drives the potentiometer being connected in motor speed adjusting module to rotate simultaneously, with this, change the size that speed adjusting module is exported to dc motor electric current.
When elbow joint need to change the direction of motion, such as the rotation from downward changes rotation upwards into, now steering wheel receives after control signal, by original clockwise rotating, change into and rotate counterclockwise, two circular discs structure motion directions change thereupon, under two circular discs structures, be distributed with two double-point double-throw switch, four spatial relation is, if two dish structures are positioned on the horizontal plane of a space coordinates, the alignment of two double-point double-throw switch, it first is stirred in the orthographic projection of the axis of position in two circular discs structures.Connecting rod is connecting the cap of stirring of two double-point double-throw switch, and bar locking cap is positioned at the center of two double-point double-throw switch length mid point connecting lines.After two dish structure motion directions change into counterclockwise, stir two double-point double-throw switch, the sense of current of two dc motors also makes a change thereupon simultaneously, and final elbow joint rotation direction changes.The stainless steel substrates being embedded in circular discs structure is crescent, the effect of this structure when it is bent on different directions needed power be different, if this crescent is reduced to a part of circular arc of a circle, the power needing while bending in the direction to there being the center of circle to disperse is outwardly larger, otherwise less, utilize this specific character to realize the control to double-point double-throw switch.In the control of drive unit, adopted steering wheel structure, object is for simplified structure, reduces cost.
If the dc motor in elbow joint part-structure is wanted to obtain larger moment output, volume is also larger, and one of object that shoulder joint part hydraulic cylinder is set is exactly to make up this shortcoming, so that mechanical arm can be picked up larger load.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
