Abstract
The utility model discloses a rotary working arm, which comprises a first arm, a second arm, a third arm, a first arm oil cylinder and a second arm oil cylinder, wherein a slewing gear is arranged between the second arm and the third arm; the slewing gear comprises a connection frame, a rotary hydraulic motor and a rotary support, wherein one end of the connection frame is respectively connected with the second arm oil cylinder and the second arm by hinge pins; the other end of the connection frame is connected with the outer ring of the rotary support; the inner ring of the rotary support is connected with the third arm by a bolt; and the rotary hydraulic motor is fixedly arranged in the connection frame by a bolt and is meshed with the inner teeth of the rotary support. According to the rotary working arm disclosed by the utility model, a hydraulic motor gear rotation device is additionally arranged on the basis of the traditional working arm, the 360-degree rotary function of the three arms is realized, and accessories, such as a hydraulic hammer, hydraulic shears and a hydraulic clamp connected with the three arms, can work within the 360-degree stereoscopic range so as to enlarge the working range and improve the working efficiency.
Description
Technical field
The utility model relates to a kind of rotary working arm equipment, is applicable to distance type robot or digging machine.
Background technology
Working arm mechanism is mainly used on robot or the digging machine, can effectively increase operating radius.But when platform is motionless, the movement locus of conventional operation arm can only be on a face, can't satisfy the demands in some particular job occasion, influenced operating efficiency, as shown in Figure 3, be connected if working arm is directly cut with hydraulic pressure, it can only shear object in a direction so, and object can not be put neatly in real work.If so working arm can realize that 3 D stereo rotatablely moves, will increase work efficiency largely.In addition, in the patent of ZL2010102656623, multifunctional universal quick coupler and working arm are used, make the accessory that is connected on the multifunctional universal quick coupler possess spinfunction, but because multifunctional universal quick coupler can not bear excessive shock loading, so the accessory that hydraulic hammer etc. has a shock loading just can not be connected use with multifunctional universal quick coupler.
Summary of the invention
Problem to be solved in the utility model provides a kind of rotary working arm, and multiple accessories such as it can be cut with hydraulic hammer, hydraulic pressure, hydraulic tongs are connected, and make accessory can realize 360 ° of comprehensive work.
A kind of rotary working arm of the utility model, comprise an arm, two arms, three arms, an arm oil cylinder, two arm oil cylinders, it is characterized in that: between two arms and three arms, be provided with a slewing equipment, slewing equipment comprises link, rotary fluid motor, revolution support, one end of link is connected with two arm oil cylinders, two arms by bearing pin respectively, and the outer ring that the other end supports by screw and revolution links to each other; The inner ring that revolution is supported is connected with three arms by screw; Rotary fluid motor is screwed in link inside, and it is meshed with the internal tooth that revolution is supported.
The utility model is to increase a hydraulic motor gear whirligig on the basis of conventional operation arm, has realized 360 ° of spinfunctions of three arms, and accessories such as the hydraulic hammer, the hydraulic pressure that are connected with three arms are cut, hydraulic tongs can be worked in 360 ° of three-dimensional scopes.The utility model can make accessory adjust to an appropriate orientation job, thereby enlarge working range according to shape and the position rotary work arm of accessory striking point when operation like this, has improved operating efficiency.

Fig. 2 is the enlarged diagram at A place among Fig. 1;
Fig. 3 is the cutaway view along B-B line among Fig. 2;
Fig. 4 is the use schematic diagram of work on hand arm.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
From Fig. 1, Fig. 2 as can be known, a kind of rotary working arm of the utility model, comprise an arm 1, two arms 2, three arms 3, an arm oil cylinder 12, two arm oil cylinders 10, be provided with a whirligig between two arms 2 and three arms 3, whirligig comprises link 6, rotary fluid motor 7, revolution support 8; One end of link 6 is connected with two arm oil cylinders 10, two arms 2 by bearing pin 4,5, and the other end links to each other by the outer ring of screw 9 and revolution support 8; The inner ring of revolution support 8 is connected with three arms 3 by screw 11; Rotary fluid motor 7 usefulness screws 13 are fixed on link 6 inside, and it is meshed with the internal tooth of revolution support 8.
Under normal conditions, robot or digging machine body realize the Telescopic of working arm for an arm oil cylinder 12, two arm oil cylinders, 10 feed flows: when giving rotary fluid motor 7 feed flows, rotary fluid motor 7 begins to rotate, because the tooth of rotary fluid motor 7 supports the engagement of 8 internal tooths with revolution, therefore the rotation of 8 inner rings is supported in revolution, and does not rotate revolution support 8 outer rings, because revolution is supported 8 inner ring and is connected with three arms 3, so 360 ° of stereo rotating that realized three arms 3 and be connected in the work accessory on three arms 3 are moved.
Rotary working arm is to have increased by one group of hydraulic motor and revolution supporting mechanism between two arms and three arms, realize spinfunction, the impulsive force that this engagement system can be born than the turbine and worm engagement of multifunctional universal quick coupler is big, and the shock loading in hydraulic hammer when work can not be applied directly in the mechanism yet, so it can connect accessories such as hydraulic hammer, hydraulic pressure are cut, hydraulic tongs.
The utility model is compared with original technology has following advantage: rotary working arm can be according to the position of operating point, by the rotary work arm work accessory is adjusted to a suitable position, more effectively three-dimensional strike, enlarged working range, made and operate also convenient, hommization.
