Description

The material grasping manipulator of three dimensions operation

Technical field:

The utility model relates generally to a kind of mechanical field, relate in particular to the material grasping manipulator of a kind of three dimensions operation, as safety, carry tube-shaped material on the full-automatic assembly line in various solar water heater factory, automobile component factory and the household electrical appliance factory fast, accurately.

Technical background:

The manipulator that uses on the general automation assembly line all is cantilevered, generally have only two positions during grabbing workpiece: pick up from a station and be put into another station, what grasp if desired is the words of the bigger tubular article of diameter, this structure is because of realizing open and close function in a big way, so can't grasp.And manufacturer when running into the bigger tubular article workpiece of this diameter unique way that can usefulness use a dead lift exactly, if the space on the production line allows manually to carry back and forth workpiece, and workpiece is less again, though this kind of a dead lift method is feasible, can bring confusion to be difficult to management to the production scene, also easy defective work piece, if workpiece too greatly and heavier again, not only labour intensity is big, wastes time and energy, inefficiency, and only can't realize producing in batches with a dead lift.

The utility model content:

The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of material grasping manipulator of three dimensions operation is provided, can difformity and the size cylindrical workpiece safe and reliable be transported to another one or several position from an appointed positions, save the space to greatest extent, save manpower, satisfy the production requirement of automatic production line.

The utility model is achieved through the following technical solutions:

A kind of material grasping manipulator of three dimensions operation, include two columns, it is characterized in that: be installed with crossbeam on the described column, one end of described crossbeam is installed with motor, the other end of described crossbeam is installed with sprocket wheel, be connected by chain drive between described sprocket wheel and the motor, described crossbeam middle part is slidingly fitted with mobile adjustable shelf, and be stuck in by clamp on the chain of crossbeam top opposite position, described moving active plate middle part is separately installed with the lifting cylinder, the piston rod of described lifting cylinder is downward, and the piston-rod lower end that promotes cylinder is fixedly connected with up and down, described up and down two ends are separately installed with the clamping cylinder, the piston rod that clamps cylinder stretches out laterally, on the piston rod of clamping cylinder two clamp jaws down are installed, holding workpiece between the described clamp jaw, the clamping face of described clamp jaw is respectively arcwall face.

The material grasping manipulator of described three dimensions operation is characterized in that on the described crossbeam bar-shaped trough being arranged, and described mobile adjustable shelf is positioned at the top of bar-shaped trough, and mobile adjustable shelf promotes piston rod left and right moving in bar-shaped trough of cylinder when crossbeam slides.

The utility model adopts the bridge type manipulator, pass through programmable controller controls, what not only span can be done is bigger, be applicable to that workpiece in a big way grasps, manipulator adopts with grasping and put down workpiece in the optional position of crossbeam after the corresponding electrical equipment control simultaneously, and the stroke up and down of grabbing workpiece can be regulated arbitrarily, after only need choosing suitable cylinder stroke during work and changing the material folding pawl of required form and length, can grasp the tube shape component of various diameters and length and width, the contact-making surface of clamp jaw and workpiece is designed to arcwall face respectively, has avoided in the extracting process damage to workpiece.

The utlity model has compact conformation, simple, control realizes easily, adaptive capacity is strong, be suitable for face width, characteristics such as safe and reliable, can difformity and the size cylindrical workpiece safe and reliable be transported to another one or several position from an appointed positions, satisfy the production requirement of automatic production line.

Description of drawings:

Fig. 1 is the utility model structural representation.

The specific embodiment:

A kind of material grasping manipulator of three dimensions operation, include two columns 13, be installed with crossbeam 9 on two columns 13, one end of described crossbeam 9 is installed with motor 4, the other end of described crossbeam 9 is installed with sprocket wheel 5, be connected by chain 6 between described sprocket wheel 5 and the motor 4, there is bar-shaped trough at described crossbeam 9 middle parts, the bar-shaped trough top of crossbeam 9 is slidingly fitted with mobile adjustable shelf 8, mobile adjustable shelf 8 is stuck on the chain 6 of crossbeam 9 top opposite positions by clamp 7, described moving active plate 8 middle parts are separately installed with and promote cylinder 1, the piston rod of described lifting cylinder 1 is downward and stretch out outside the crossbeam downwards from bar-shaped trough, piston-rod lower end is fixedly connected with up and down 12, described up and down 12 two ends are separately installed with and clamp cylinder 3, clamp on cylinder 3 piston rods and are installed with movable clamping jaws 11 respectively, and moving respectively of described clamp jaw 11 drives by clamping cylinder 3, holding workpiece 2 between the described clamp jaw 11, and the clamping face of clamp jaw 11 is respectively arcwall face.

During work, at first in the I of position, after cylinder 1 ejects and drives up and down 12 position that drops to workpiece 2 places, cylinder 3 signal closes, clamp jaw 11 is held workpiece 2 tightly, workpiece is mentioned in cylinder 1 withdrawal.Motor 4 begins action and drives sprocket wheel 5, chain 6 rotations; Chain 6 usefulness clamps 7 are stuck on mobile adjustable shelf 8, and chain drags the reciprocating action on crossbeam 9 of mobile adjustable shelf 8, and mobile adjustable shelf 8 moves behind the II of position, and cylinder 1 ejects; Drop to for up and down 8 on the processing stations 10, open after cylinder 3 gets signal; After putting down workpiece 2, cylinder 1 withdrawal; Rise for up and down 12; Manufacturing procedure on the wait station 10 is finished.Provide signal after operation is finished, after cylinder 1 ejected up and down 12 descending putting in place of drive once more, cylinder 3 drove the clamp jaw closures; Hold workpiece 2 tightly; Repeat above-mentioned action workpiece is transported to position III.
