The clamping mechanical hand of resultant motion track
Technical field: the invention belongs to transfer robot field, is specifically related to a kind of resultant motion track clamping mechanical hand.
Background technology: clamping mechanical hand, because replacing manually, enhance productivity, is widely used in automated production.But the clamping mechanical hand great majority of production application rely on multi-axis servo motor to drive ball screw synthesis to realize its motor function at present, and shortcoming is: one, machine driving and electrical equipment control complexity, easily breaks down; Two, productive temp is slow; Three, owing to adopting multi-axis servo motor and precision drive parts, manufacturing cost and maintenance cost high.
Summary of the invention: object of the present invention is exactly the clamping mechanical hand proposing a kind of resultant motion track, to solve existing for background technology: machine driving and electrical equipment control complexity, easily breaks down; Productive temp is slow; Manufacturing cost and maintenance cost are very high.
Technical scheme of the present invention is: a kind of resultant motion track clamping mechanical hand, it is characterized in that: carriage center is provided with rack shaft in hole, cylinder piston rod on the lower end of rack shaft and support is connected, pedestal upper end face is provided with gear-box, gear-box inner chamber is arranged with two gear shafts, the front end of each gear shaft is equipped with wheel and rack axle and connects, each gear the tip of the axis is equipped with disk, gear-box drive end bearing bracket is equipped with skewed slot with disk correspondence position, be provided with slide block in each skewed slot, slip front face is connected with corresponding jaw; Slide block rear end face is provided with chute, is provided with pulley in chute, and pulley and disk are connected, and is provided with pin in jaw front end.
The invention has the beneficial effects as follows: owing to have employed technique scheme, rack shaft is pulled to move up and down by cylinder, two gear shafts symmetrical in driven gear case rotate, by the pulley on disk, band movable slider slides in skewed slot, drive jaw action, realize two jaws and move up and down and synthesize with the action of horizontal folding, play and promote and clamp, fall and open the effect synchronously carried out.There is reliable in action, productive temp be fast, efficiency is high, the advantage of low cost of manufacture.
Accompanying drawing illustrates: be described in further details technical scheme of the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention.

Detailed description of the invention: with reference to figure 1-Fig. 3.A kind of resultant motion track clamping mechanical hand, rack shaft 2 is provided with in support 1 centre bore, cylinder 3 piston rod on the lower end of rack shaft 2 and support is connected, support 1 upper surface is provided with gear-box 4, gear-box 4 inner chamber is arranged with two gear shafts 6, the front end of each gear shaft 6 is equipped with gear 5 and is connected with rack shaft 2, the end of each gear shaft 6 is equipped with disk 7, gear-box 4 drive end bearing bracket is equipped with skewed slot 10 with disk 7 correspondence position, be provided with slide block 11 in each skewed slot 10, slide block 11 front end face is connected with corresponding jaw 9; Slide block 11 rear end face is provided with chute 12, is provided with pulley 8 in chute 12, and pulley 8 and disk 7 are connected, and are provided with pin 13 in jaw 9 front end.
Operation principle: cylinder 3 piston rod stretches; rack shaft 2 is pulled to move up and down; rack shaft 2 drives two gear shafts 6 to rotate; drive the pulley 8 on corresponding disk 7 to rotate, slide block 11 is slided according to the track preset in skewed slot 10; jaw 9 is driven to move; realize two jaws 9 to move up and down and synthesize with the action of horizontal folding, play and promote and clamping, fall and open the effect synchronously carried out.
