A kind of active swing arm of high-speed parallel manipulator
The utility model relates to the active swing arm of a kind of robot, particularly a kind of high-speed parallel manipulator.
At present, existing high-speed parallel manipulator generally comprises organic frame, moving platform, is connected in the many groups swing arm between frame and moving platform and is fixed on the servomotor for driving swing arm to swing in frame, and every group of swing arm comprises that an active swing arm and is articulated with the initiatively driven swing arm of swing arm end.Active swing arm of the prior art is generally solid construction, and weight is heavier, causes manipulator very flexible when whipping, consumes energy high.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, provide a kind of can weight reduction, make manipulator more flexible when whipping, and the active swing arm of the better high-speed parallel manipulator of intensity.
The utility model adopts following technical scheme:
An active swing arm, its one end is connected in drive unit, the hinged driven swing arm of the other end, includes arm body, this arm body is hollow structure.
Further, described arm body one end is formed for the first connector of connecting drive device, and the other end is formed for the second connector of hinged driven swing arm.
Further, the arm body between described the first connector and the second connector is hollow structure.
Further, between the two side of described arm body hollow space, be connected with reinforcement.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: initiatively the arm body of swing arm is hollow structure, and be connected with reinforcement between the two side of arm body hollow space, can weight reduction, make manipulator more flexible when whipping, and intensity is better.

The specific embodiment
Below by the specific embodiment, the utility model will be further described.
With reference to Fig. 1, the active swing arm of a kind of high-speed parallel manipulator of the present utility model, includes arm body 1, and this arm body 1 is hollow structure.Described arm body 1 one end is formed for the first connector 2 of connecting drive device, and the other end is formed for the second connector 3 of hinged driven swing arm, and the arm body 1 between described the first connector 2 and the second connector 3 is hollow structure.Between the two side of described arm body 1 hollow space, be connected with reinforcement 4.
Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
