Optimally, be separately installed with one piece of liner in the inner side of described left mechanical finger and right mechanical finger, the hemispherical shape of middle part for caving inward of described liner.The frictional force of mechanical finger when gripping objects can be increased by described liner, thus play increase chucking power, prevent the effect of object landing.
Optimally, described robot carriage is T-shaped block structure, and described drive motors is bolted on robot carriage.Here robot carriage being designed to T-type structure is conveniently install two mechanical fingers, and particularly both sides, T-shaped piece of top can be connected with mechanical finger very easily, can reduce installation operation easier like this.
Optimally, described left mechanical finger is connected with left branching rod, right mechanical finger is connected with right pole, described left mechanical finger is rotatably connected by left branching rod and straight pin, and described right mechanical finger is rotatably connected by right pole and straight pin; Described left branching rod is identical with the length of right pole.
Relative to prior art, the utility model has following beneficial effect:
1, robot arm of the present utility model adopts the linked manner of ring flange and connecting rod drive separating of two mechanical fingers opened and close, the flexibility of equipment manipulation can not only be improved like this, the clamping dynamics of arm can also be strengthened, improve stability when arm uses.
2, control simply, fault rate is lower, is conducive to ensureing the sustainability of producing, and then improves production efficiency.
3, easy maintenance, owing to being all detachable connection between all parts, like this when some component failure, only need be changed, so also significantly be reduced the cost of maintenance.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model describes a kind of robot arm, and it comprises robot carriage 1, and described robot carriage 1 is T-shaped block structure, and robot carriage 1 is provided with multiple installing hole.Be provided with a drive motors 2 at the back side of described robot carriage 1, described drive motors 2 is bolted on robot carriage 1.Here drive motors 2 have employed existing motor device, can select micromachine in the market.Rotatingly in the front of described robot carriage 1 be provided with a ring flange 3, the output shaft of described drive motors 2 is connected with ring flange 3 through after robot carriage 1; When drive motors 2 works, drive motors 2 will drive ring flange 3 synchronous axial system.Described ring flange 3 is provided with a connecting rod 4, and one end of described connecting rod 4 is connected with ring flange 3 by bearing pin 5, and the other end and the straight pin 6 be arranged on robot carriage 1 of connecting rod 4 are rotatably connected.Described straight pin 6 is slidably arranged in the chute 7 in the middle part of robot carriage 1, and described chute 7 is vertically arranged, and straight pin 6 can slide up and down in chute 7.Described straight pin 6 is also connected with left mechanical finger 8 and right mechanical finger 9, described left mechanical finger 8 and right mechanical finger 9 are also rotatably connected with the upper end of robot carriage 1 respectively by the rotating shaft 10 of correspondence, when mounted, described left mechanical finger 8 and right mechanical finger 9 are symmetrical arranged, between described left mechanical finger 8 and right mechanical finger 9, be also connected with a spring 11, the chucking power of manipulator can be strengthened by spring 11.
See Fig. 1, be separately installed with one piece of liner 12 in the inner side of described left mechanical finger 8 and right mechanical finger 9, the hemispherical shape of middle part for caving inward of described liner 12.Here liner 12 can adopt quality of rubber materials, can increase the frictional force between gripping object and manipulator by the effect of liner 12.See Fig. 1 and Fig. 2, described left mechanical finger 8 is connected with left branching rod 13, right mechanical finger 9 is connected with right pole 14, and described left mechanical finger 8 is rotatably connected by left branching rod 13 and straight pin 6, and described right mechanical finger 9 is rotatably connected with straight pin 6 by right pole 14; Described left branching rod 13 is identical with the length of right pole 14.Here can strengthen the interlock flexibility of two mechanical fingers by arranging left and right pole, making it be not easy to block, rotating more simultaneously.
Operation principle: when using robot arm of the present utility model, start drive motors 2, drive ring flange 3 rotates by drive motors 2, the connecting rod 4 be connected with ring flange 3 is pushed, connecting rod 4 promotes left branching rod 13 and right pole 14 again respectively, and then drives left mechanical finger 8 and right mechanical finger 9 to produce movement forward or backward; Because left mechanical finger 8 is connected with robot carriage 1 respectively by rotating shaft 10 with right mechanical finger 9, therefore left mechanical finger 8 and right mechanical finger 9 are by respectively around respective axis of rotation, the clamp port that left like this mechanical finger 8 and right mechanical finger 9 form just defines and opens or closed action, and under the pulling of spring 11, by tight for parts to be processed clamping, the dynamics of its clamping determined by the power output of drive motors 2.
