Abstract
The invention discloses a swing arm capable of lifting, which comprises a base and vertical columns fixed on the base, wherein swing arms are fixed on the vertical columns; the swing arms can lift relative to the vertical columns; ball screws are arranged in the vertical columns; motors are connected with upper ends of the ball screws; leading screw nuts are arranged on the ball screws; the leading screw nuts are connected with the swing arms through connection seats. The swing arm capable of lifting solves the problem that in the prior art, swing arms of a welding robot mounted a workpiece inconveniently, is convenient for the mounting and detachment of the workpiece by arranging the swing arms used for fixing the workpiece to be a lifting structure, and therefore lowers the tooling difficulty.
Description
Technical field
The present invention relates to a kind of liftable swing arm, belonged to the robotic welding technology field.
Background technology
Construction machinery industry adopted artificial welding mostly in the past, and labour intensity is large, and welding quality can not be guaranteed.Began in recent years to adopt in a large number welding robot to replace the common laborer to weld, the cost that also improved yield reducation when having improved quality.In the robotic welding technology field, existing swing arm for fixing workpiece to be welded is normally highly fixing for convenient welding, for some large volumes, heavy weight workpiece, need to be fixed to certain height workpiece is too high, fixedly difficulty is large, and dismounting is also inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides a kind of liftable swing arm, by being arranged to liftable structure for the swing arm of fixation workpiece, is convenient to loading and the dismounting of workpiece.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of liftable swing arm comprises base and the column that is fixed on the described base, is fixed with swing arm on the described column, and described swing arm is with respect to described column liftable.
Aforesaid a kind of liftable swing arm is characterized in that: be provided with ball-screw in the described column, the upper end of described ball-screw is connected with motor, is provided with feed screw nut on the described ball-screw, and described feed screw nut is connected with described swing arm by Connection Block.
Aforesaid a kind of liftable swing arm is characterized in that: described swing arm is L-type.
Aforesaid a kind of liftable swing arm is characterized in that: described base is U-shaped.
Aforesaid a kind of liftable swing arm is characterized in that: also be provided with reductor between described motor and the ball-screw.
The invention has the beneficial effects as follows:
1, is arranged to liftable structure by the swing arm that is used for fixation workpiece, is convenient to loading and the dismounting of workpiece, reduced the frock difficulty;
2, swing arm is designed to L-type, is convenient to the installation and removal of workpiece, and has increased the soldering angle of robot when welding;
3, by base designs is become U-shaped, increased the reduction scope of swing arm, be convenient to the installation and removal of workpiece.
Description of drawings
Fig. 1 is the front view of a kind of liftable swing arm of the present invention;
Fig. 2 is the side view of a kind of liftable swing arm of the present invention;
Fig. 3 is the structural representation of the column of a kind of liftable swing arm of the present invention.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of liftable swing arm comprises base 1 and the column 2 that is fixed on the described base 1, is fixed with swing arm 3 on the described column 2, and described swing arm 3 is with respect to described column 2 liftables.Be arranged to liftable structure by the swing arm 2 that is used for fixation workpiece, be convenient to loading and the dismounting of workpiece, reduced the frock difficulty.
Be provided with ball-screw 23 in the column 2, the upper end of described ball-screw 23 is connected with motor 21, be provided with feed screw nut 24 on the described ball-screw 23, described feed screw nut 24 is connected with described swing arm 3 by Connection Block 25, drive the rotation of ball-screw 23 by the rotation of motor 21, move up and down at ball-screw 23 thereby drive feed screw nut 24, by moving up and down of Connection Block 25 final realization swing arms 3.
Swing arm 3 is L-type, is convenient to the installation and removal of workpiece, and has increased the soldering angle of robot when welding.
Base 1 is U-shaped, has increased the reduction scope of swing arm, is convenient to the installation and removal of workpiece.
Also be provided with reductor 22 between motor 21 and the ball-screw 23, the mode that drives ball-screw 23 by motor 21 and reductor 22 can make moving up and down of swing arm 3 more stable.
In sum, a kind of liftable swing arm provided by the invention by being arranged to liftable structure for the swing arm of fixation workpiece, is convenient to loading and the dismounting of workpiece.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
