Background technology
Six-joint robot is free in three dimensions to carry out activity, it is possible to carries out quickly and accurately carrying, weld, a large amount of repetitive works such as spraying.In traditional industry manufacture field, the work such as carrying, welding is substantially main by manually completing, and there is labor intensity more, uninteresting, work under bad environment big, consuming time, easily causes the problems such as pollution.Manual operation is difficult to make technique reach concordance so that quality is not easily controlled, thus the cost of enterprise can be increased.Therefore, in these areas, be pole need robot quickly and accurately material to be carried, install, weld, the operation such as spraying.
But existing six-joint robot is in actual use, there is also problems, specific to six-joint robot main manifestations in the following areas: 1) structure bulky, the six-joint robot overall load ability being declines;2) cabling is mixed and disorderly, and cable is short for service life;3) integral rigidity is low, self load bearing ability.
Utility model content
The purpose of this utility model is to provide a kind of big arm configuration of industrial six-joint robot, it possesses reasonable in design, cabling is clear, the advantage that deadweight is relatively light and rigidity is big, adopts the big arm configuration of industrial six-joint robot of the present utility model can strengthen its rigidity while alleviating large arm own wt so that it is weight capacity strengthens, additionally, double; two large arm structural designs that the application adopts so that the second axle installing port and machine power transmission channels are arranged apart, can extend the service life of cable.
For solving himself heaviness of the big arm configuration of six-joint robot in prior art, rigidity is low, cable arrangement is numerous and diverse, the technical problem that service life is short, the one big arm configuration of industrial six-joint robot that this utility model provides, including the left large arm beam be arrangeding in parallel and right large arm beam, the rear end of left large arm beam and right large arm beam is all fixing with the second axle connecting portion to be connected, left large arm beam and right large arm beam are the bathtub construction of outward opening and are provided with the 3rd spindle motor installation case in both rear ends, install case inner chamber respectively with left large arm beam, the flute profile position connection of right large arm beam forms " U " word moulding cavity, the front end of left large arm beam adopts circular arc and offers the 3rd axle power pass-through in its groove bottom wall, the front end of right large arm beam adopts circular arc and offers the 3rd axle installing port in its groove bottom wall;Second axle connecting portion is between the rearward end of left large arm beam and right large arm beam, second axle connecting portion offers inner chamber, the inner chamber of the second axle connecting portion connects with installing box cavity, the rear end of the second axle connecting portion adopts circular arc close and offer the second axle installing port to the left, the rear end of the second axle connecting portion adopts circular arc close and be provided with the second axle mounting flange on the right side of it, and the second axle connecting portion and left large arm beam or right large arm beam be arranged in parallel.
Further, a kind of big arm configuration of industrial six-joint robot of this utility model, wherein, the connecting portion installing case and the front end face between left large arm beam and right large arm beam and sidewall is provided with arc-shaped concave.
A kind of big arm configuration of industrial six-joint robot of this utility model is compared with prior art, have the advantage that this utility model adopts arm structure design, this structure makes cable transmission channels and machine power transmission channels be spaced from each other, structure is arranged clear, extend cable service life, it addition, the design installing case makes the connection between each parts more compact, integral rigidity improves, and weight capacity effectively strengthens.
Below in conjunction with detailed description of the invention shown in accompanying drawing, a kind of big arm configuration of industrial six-joint robot of this utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is a kind of industrial six-joint robot big arm configuration one orientation of this utility model schematic diagram;
Fig. 2 is a kind of industrial six-joint robot big arm configuration another kind orientation of this utility model schematic diagram.
Wherein: 1, left large arm beam;2, right large arm beam;3, the second axle connecting portion;4, case is installed;5, the 3rd axle power pass-through;6, the 3rd axle installing port;7, the second axle installing port;8, the second axle mounting flange;9, arc-shaped concave.
Detailed description of the invention
Firstly the need of what illustrate it is; left and right described in this utility model application, front and back and above-below direction are all with left large arm beam and right large arm beam from the second axle connecting portion to the 3rd axle power pass-through or the 3rd axle installing port for dead ahead to being as the criterion; and its regulation simply conveniently carried out for statement, it is not offered as the restriction that the scope that is claimed of this utility model patent application is carried out.
nullAs depicted in figs. 1 and 2,A kind of big arm configuration of industrial six-joint robot of this utility model,Including the parallel left large arm beam 1 being provided with and right large arm beam 2,The rear end of left large arm beam 1 and right large arm beam 2 is all fixing with the second axle connecting portion 3 to be connected,Left large arm beam 1 and right large arm beam 2 are the bathtub construction of outward opening and are provided with the 3rd spindle motor installation case 4 in both rear ends,Install case 4 inner chamber respectively with left large arm beam 1、The flute profile position connection of right large arm beam 2 forms " U " word moulding cavity,The front end of left large arm beam 1 adopts circular arc and offers the 3rd axle power pass-through 5 in its groove bottom wall,The front end of right large arm beam 2 adopts circular arc and offers the 3rd axle installing port 6 in its groove bottom wall,By arm structure design, cable transmission channels and machine power transmission channels are spaced from each other,Structure is arranged clear,Extend cable service life,Additionally,The design installing case 4 makes the connection between each parts more compact,Integral rigidity improves,Weight capacity strengthens;Second axle connecting portion 3 is between the rearward end of left large arm beam 1 and right large arm beam 2, second axle connecting portion 3 offers inner chamber, the inner chamber of the second axle connecting portion 3 and installation case 4 inner space, the 3rd spindle motor and end-equipment cable wiring it is easy to by this setting, the rear end of the second axle connecting portion 3 adopts circular arc close and offer the second axle installing port 7 to the left, the rear end of the second axle connecting portion 3 adopts circular arc close and be provided with the second axle mounting flange 8 on the right side of it, and the second axle connecting portion 3 and left large arm beam 1 or right large arm beam 2 be arranged in parallel.
As further prioritization scheme, the connecting portion installing case 4 and the front end face between left large arm beam 1 and right large arm beam 2 and sidewall is provided with arc-shaped concave 9, this is provided with so that the free space of end-equipment expands, and arc-shaped concave 9 slow down stress concentration phenomenon, extends service life of equipment.
Above example is only the description that preferred implementation of the present utility model is carried out; not this utility model is claimed the restriction that scope carries out; under the premise without departing from this utility model design principle and spirit; the various forms of deformation that this area engineers and technicians make according to the technical solution of the utility model, all should fall in the protection domain that claims of the present utility model are determined.
