As preferably, the length of two rhizoid thick sticks is equal, and the ring that walks corresponding to two handgrips is symmetrical about the tie point of two rhizoid thick sticks.
As preferably, described leading screw is parallel with crossbeam.
As preferably, two rhizoid thick sticks are all fixed on crossbeam side by bearing block away from the two ends of junction, and wherein a rhizoid thick stick is connected with servo motor transmission.
As preferably, the upper end of described handgrip is slidably connected by slide block and crossbeam, described in the ring that walks be fixedly connected with slide block.
As preferably, described servomotor is controlled by PLC.
The invention has the beneficial effects as follows, this novel adjustable robot gripper adopts single servomotor to drive, the distance adjustment of handgrip is realized with the leading screw that two hand of spirals are contrary, compared to prior art, decrease the use of a servomotor, decrease the production cost of product, improve the competitiveness of product, also mitigate the overall weight of device, add the maximum weight that device captures material, improve operating efficiency.

Fig. 2 is the structural representation of the bar that walks of novel adjustable robot gripper of the present invention;
In figure: 1. crossbeam, 2. fixed head, 3. servomotor, 4. walk bar, 5. handgrip, and 6. walk ring hand, 7. bearing block, 8. slide block, 41. leading screws.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1-2, a kind of novel adjustable robot gripper, comprise coupling assembling and grabbing assembly, described grabbing assembly is arranged on below coupling assembling, described coupling assembling comprises two crossbeams 1 arranged in parallel, fixed head 2 is provided with above described two crossbeams 1, described fixed head 2 two ends are fixedly connected with two crossbeams 1 respectively, driven unit is provided with between two crossbeams 1, the bar 4 that walks that described driven unit comprises servomotor 3 and is in transmission connection with servomotor 3, the described bar 4 that walks comprises two and is fixedly connected with and the contrary leading screw 41 of hand of spiral, the axis of two rhizoid thick sticks 41 on the same line, described grabbing assembly comprises two symmetrically arranged handgrips 5, upper end and the crossbeam 1 of described handgrip 5 are slidably connected, two handgrips 5 are in transmission connection respectively by walk ring 6 and two rhizoid thick sticks 41.
As preferably, the length of two rhizoid thick sticks 41 is equal, and the ring 6 that walks corresponding to two handgrips 5 is symmetrical about the tie point of two rhizoid thick sticks 41.
As preferably, described leading screw 41 is parallel with crossbeam 1.
As preferably, two rhizoid thick sticks 41 are all fixed on crossbeam 1 side by bearing block 7 away from the two ends of junction, and wherein a rhizoid thick stick 41 is in transmission connection with servomotor 3.
As preferably, the upper end of described handgrip 5 is slidably connected by slide block 8 and crossbeam 1, described in the ring 6 that walks be fixedly connected with slide block 8.
As preferably, described servomotor 3 is controlled by PLC.
Under the control of PLC, the corresponding rotation of servomotor 3, and under the rotary actuation of servomotor 3, two rhizoid thick sticks 41 all with the rotating shaft rotating in same direction of servomotor 3, because the hand of spiral of two rhizoid thick sticks 41 is contrary, so two rhizoid thick sticks 41 drive two walk ring 6 along in opposite directions or rightabout move, thus realize distance between two handgrips 5 and reduce or increase.
In normal technology thinking, want driving two handgrips 5 to move along on the contrary or in opposite directions direction, the technical scheme adopted carries out transmission with the leading screw 41 that two servomotors 3 drive two hand of spirals contrary, if only adopt a servomotor 3, then will wherein fix by a lobe handgrip 5, realized increase or the reduction of the spacing of two lobe handgrips 5 again by the movement of an other lobe handgrip 5, the efficiency of such action is not high yet.
Compared with prior art, this novel adjustable robot gripper adopts single servomotor 3 to drive, the distance adjustment of handgrip is realized with the leading screw 41 that two hand of spirals are contrary, compared to prior art, decrease the use of a servomotor 3, decrease the production cost of product, improve the competitiveness of product, also mitigate the overall weight of device, add the maximum weight that device captures material, improve operating efficiency.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
