Description

Roll-over type mechanical arm

Technical field

The utility model relates to the manipulator that is used for food packing machine and field of pharmaceutical machinery, relates in particular to a kind of roll-over type mechanical arm.

Background technology

Current, roll-over type mechanical arm has obtained utilization at large in food packing machine and field of pharmaceutical machinery.Notification number is the Chinese patent literature of CN201257664Y, a kind of roll-over type mechanical arm is disclosed, the upset of this manipulator is by the tooth bar and the turning gear engagement that is fixedly connected on the left pawl rotating shaft that are installed in the upset control cam control moving linearly on the master arm, make rack drives turning gear Rotate 180 degree, thereby realize the inversion of bottle.Yet above-mentioned turning manipulator is because of introducing upset control cam, and difficulty of processing, structure are complicated, cost is also higher thereby increased.Moreover the cooperation of rack-and-pinion need could be worked under the lubricating oil environment usually better, rack-and-pinion is exposed in the working environment can produces to pollute, and is unsuitable for being used in the working environment that cleanliness factor has relatively high expectations.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple and compact for structure, with low cost, roll-over type mechanical arm that applicability is strong is provided.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of roll-over type mechanical arm, comprise master arm, slave arm and a pair of jaw that can overturn synchronously, be equiped with the wobble component that is used to drive the master arm swing on the described master arm, described master arm rear end is connected by gear pair with the slave arm rear end, the described a pair of jaw that can overturn synchronously is divided on master arm and the slave arm, is equiped with the rotary drive that can drive the jaw upset at least one the jaw.

Described rotary drive is rotary cylinder or rotary oil cylinder or rotating servo motor.

In the described a pair of jaw, one is formed with draw-in groove, and another part is formed with the Ka Tai that cooperates with described draw-in groove, and described Ka Tai placed in the described draw-in groove when a pair of jaw was closed.

Be provided with the fastening spring that can order about master arm and slave arm auto-closing between described master arm and the slave arm.

Compared with prior art, advantage of the present utility model is:

Roll-over type mechanical arm of the present utility model, directly at jaw installing rotary drive, a pair of jaw that the upset power that provides by rotary drive can drive on it overturns synchronously, and is simple and compact for structure, with low cost; Simultaneously, the output revolving shaft of rotary drive is only made circular motion, and does not make stretching motion, and the fluid of rotary drive inside can not flow out and pollute working environment, so roll-over type mechanical arm of the present utility model goes in the working environment that cleanliness factor has relatively high expectations, the scope of application is wider.

The specific embodiment

Fig. 1 to Fig. 4 shows a kind of roll-over type mechanical arm embodiment of the present utility model, this roll-over type mechanical arm comprises master arm 1, slave arm 2 and a pair of jaw that can overturn synchronously 6, be equiped with the wobble component 4 that is used to drive master arm 1 swing on the master arm 1, master arm 1 rear end is connected by gear pair 7 with slave arm 2 rear ends, the a pair of jaw that can overturn synchronously 6 is divided on master arm 1 and the slave arm 2, is equiped with the rotary drive 5 that can drive jaw 6 upsets at least one the jaw 6.When wobble component 4 drove master arm 1 swing, master arm 1 drove slave arm 2 by gear pair 7 and swings synchronously, and master arm 1 and slave arm 2 drive a pair of jaw 6 and open.The a pair of jaw 6 that the upset power that provides by rotary drive 5 can drive on it overturns synchronously, and is simple and compact for structure, with low cost; Simultaneously, the output revolving shaft of rotary drive 5 is only made circular motion, and does not make stretching motion, and the fluid of rotary drive 5 inside can not flow out and pollute working environment, so roll-over type mechanical arm of the present utility model goes in the working environment that cleanliness factor has relatively high expectations, the scope of application is wider.

Rotary drive 5 is rotary cylinder or rotary oil cylinder or rotating servo motor, in the present embodiment, selects rotary cylinder for use.In order better to reduce cost, in the present embodiment, rotary drive 5 only is installed on the jaw 6 of slave arm 2, and in a pair of jaw 6, one be set as have draw-in groove 61, another part is set as and has the card platform 63 that cooperates with draw-in groove 61, card platform 63 placed in the draw-in groove 61 when a pair of jaw 6 was closed, the jaw 6 that makes this part that rotary drive 5 is installed cooperates with another part jaw 6, reach two jaws 6 purpose of upset synchronously, in other embodiments, rotary drive 5 also can be replaced by slave arm 2 and be located on the master arm 1, or master arm 1 and slave arm 2 are installed rotary drive 5 simultaneously.When master arm 1 and slave arm 2 are installed rotary drive 5 simultaneously, on the jaw 6 draw-in groove 61 and Ka Tai 63 can be set, only need to guarantee that the rotary drive 5 simultaneously synchronous Equidirectional overturnings of going up separately get final product.In the present embodiment, wobble component 4 comprises swing arm 41 and is located at the rolling bearing 43 of swing arm 41 1 ends, and swing arm 41 and master arm 1 are packed on the non-circular shaft 9 by the non-circular hole of offering on separately 8 respectively; Be provided with the fastening spring 3 that can order about master arm 1 and slave arm 2 auto-closings between master arm 1 and the slave arm 2.

Operation principle: master arm 1 produces swing under the driving of wobble component 4, master arm 1 is swung synchronously by gear pair 7 drive slave arms 2 simultaneously, master arm 1 and slave arm 2 relative opening, fastening spring 3 and drive a pair of jaw 6 and open simultaneously stretches, with the clamping of bottle neck, fastening spring 3 is replied the steady bottle of back folder by jaw 6.Follow rotary drive 5 outputting rotary powers, turn over turnback to drive connected jaw 6,, make two jaws 6 be able to common upset because of two jaws 6 cooperate by draw-in groove 61 and Ka Tai 63, the upset of bottle is finished towards just exchanging in the bottleneck that is held bottle and the bottle end.

Above-mentioned is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model.Any those of ordinary skill in the art, under the situation that does not break away from the technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solutions of the utility model, all should drop in the scope of technical solutions of the utility model protection any simple modification, equivalent variations and modification that above embodiment did according to the utility model technical spirit.
