Singly refer to clamp turning manipulator
Technical field
The present invention relates to the manipulator of hollow round column shape workpiece in a kind of gripping, in particular for wheel industry wheel rim loading and unloading work, singly refer to clamp turning manipulator.
Background technology
At present, the existing manipulator for gripping wheel rim is all to adopt two or more fingers, by hinge or gear, connects, and in the mode of holding tightly, carries wheel rim, carries out lathe loading and unloading work.But, this mode complex structure, volume is large, and high to lathe space requirement, the scope of application is little.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of turning manipulator that singly refers to clamp is provided, this manipulator not only can be realized accurate location and the quick fetching of wheel rim, and compact conformation, take up room little.
For realizing above-mentioned technical purpose, scheme provided by the invention is: a kind ofly singly refer to clamp turning manipulator, comprise the support that is provided with finger, one end and the returning face plate of described support are hinged; One end and the support of upset cylinder are hinged, and its other end and returning face plate are hinged; One end and the returning face plate of clamping cylinder are hinged, and its other end is hinged with finger; Mounting frame for sensor is set on returning face plate, on this mounting frame for sensor, approach switch is set.
And, on described support, with the rear of returning face plate hinged place, limited block is set.
And, on the face that the bottom of described returning face plate contacts with workpiece, lanyard is set.
The invention has the beneficial effects as follows, compact conformation, takes up room little, and power is simple, and gripping efficiency is high, and accurate positioning picks and places rapidly.

The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
The present embodiment provides a kind of turning manipulator that singly refers to clamp, and comprises the support that is provided with finger, and as depicted in figs. 1 and 2, one end of support 9 and returning face plate 4 are hinged, and one end and the support 9 of upset cylinder 8 are hinged, and its other end and returning face plate 4 are hinged; One end of clamping cylinder 7 and returning face plate 4 are hinged, and its other end is hinged with finger 1; Mounting frame for sensor 3 is set on returning face plate 4, on this mounting frame for sensor 3, approach switch 2 is set; On support 9, with the rear of returning face plate 4 hinged places, limited block 6 is set, lanyard 5 is arranged on returning face plate 4 bottoms.Lanyard 5 can adopt elastomeric material, the collision of workpiece can reduce work time to manipulator, and two can strengthen the friction between manipulator and workpiece, play the effect of stablizing workpiece in transportation.
During work, after wheel rim is located in raceway, clamping cylinder 7 action, points 1 clamping work pieces, and approach switch 2 detects after finger 1 clamping work pieces, 8 actions of upset cylinder, will point 1 and wheel rim overturn together 90 °, send in lathe.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement or distortion, these improvement or distortion also should be considered as protection scope of the present invention.
