The grabbing mechanism can achieve the result that one clamping action can realize the laminated sheet positioning in the workpiece, thereby compared with other structural modes, in the whole process of grabbing, positioning, transmission and emptying, the grabbing mechanism saves a plurality of redundant working procedures, has novel design on the structure, and also simplifies the complex structure so as to realize miniaturizationand improve the efficiency of the mechanism.
Description
Technical field:
The utility model relates to a kind of grasping mechanism of grasping laminating workpiece, relate in particular to a kind ofly can grasp flexibly, the disposable grasping mechanism that moves stacked workpiece.
Background technology:
At present, in the automatic production assembling process of industrialization, can run into the workpiece of setting up jointly by lamination stack, as the stator lasmination of motor.In some cases, these laminations often will insert the rivet (as straight body rivet) of matched in clearance before riveted joint, with this preparation as subsequent processing (riveting molding).Because the matched in clearance of mobility between each lamination and straight body rivet causes the deformability of whole work-piece and the possibility that rivet slides and falls.Just because of this phenomenon, can bring all difficulties to clamping, location, the transmission of this type of workpiece.
At this type of situation, the applicant is devoted to research and design in this respect always, in the process of constantly bringing forth new ideas, has invented the grasping mechanism that the lamination that can realize in the workpiece and rivet are located simultaneously.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of grasping mechanism of grasping laminating workpiece is provided, this grasping mechanism can reach once and to clamp the result that action can realize that lamination location in the workpiece or lamination and rivet are located simultaneously, like this in the overall process of extracting, location, transmission, blowing, contrast other frame mode, saved some " unnecessary operations ", simplified complicated structure again.Thereby can realize miniaturization and improve mechanical efficient.
The technical scheme that the utility model solves prior art is: a kind of grasping mechanism of grasping laminating workpiece, comprise bearing, by the cylinder of bearing support, the grabbing device that is connected with cylinder, this grasping mechanism is installed on the mobile machine arm, stacked workpiece is laminated by some blocks of thin laminations, wherein grabbing device is that a cover can be realized the disposable clamping assembly of finishing extracting, location, transmission, neat blowing four big functions of stacked workpiece, and this clamping assembly comprises:
---connect the movable claw that the cylinder output is provided with the vertical cylinder direction of action, the position of corresponding stacked workpiece bottom of movable claw and middle and upper part is respectively equipped with at least 2 boss;
---rest base is in the fixed arm that is extended with a vertical cylinder direction of action, and fixed arm is provided with the middle boss of corresponding movable claw in the side of facing movament pawl, and middle boss is corresponding to the pit between each boss of movable claw; Fixed arm is provided with the elasticity reset device of corresponding movable claw boss quantity in middle boss upper and lower sides, this elasticity reset device points to movable claw one end by the bolt that penetrates fixed arm, bolt and is connected with a sideboard, is socketed between sideboard and the fixed arm by a back-moving spring, the adjusting nut that is fastened to the bolt other end and forms, regulates bolt and can make sideboard fair in non-stress state and middle boss plane;
Boss on the movable claw, elasticity reset device and middle boss form at least 2 pairs of shearing idols to stacked workpiece, when cylinder inwardly bounces back, drive movable claw and press to stacked workpiece, the lamination of the boss compressing correspondence position on the movable claw promotes corresponding sideboard, the bottom of stacked workpiece and middle and upper part lamination are in compress positioning states, this moment, workpiece was done to move and each lamination can not come off; After workpiece moved to assigned address, cylinder outwards promoted movable claw, and the boss on the movable claw disappears to the active force of lamination, and the lamination of sideboard dislocation before inciting somebody to action under the effect of back-moving spring simultaneously pushes back neat position.
As the further description to the aforementioned techniques scheme: described stacked workpiece is provided with vertical through hole, inserts the rivet of matched in clearance in the through hole; The boss protrusion height of described movable claw is a bit larger tham the gap size of rivet between the lamination through hole; Sideboard is a bit larger tham the gap size of rivet between the lamination through hole in the distance between non-stress state and the fixed arm;
When cylinder inwardly bounces back, drive movable claw and press to stacked workpiece, the lamination of the boss compressing correspondence position on the movable claw promotes corresponding sideboard, rivet also is subjected at least 2 pairs of shearing idols simultaneously, the bottom of stacked workpiece and middle and upper part lamination are in compress positioning states, this moment, workpiece was done to move and each lamination and rivet can not come off; After workpiece moved to assigned address, cylinder outwards promoted movable claw, and the boss on the movable claw disappears to the active force of lamination, and the lamination of sideboard dislocation before inciting somebody to action under the effect of back-moving spring simultaneously pushes back neat position.
As further describing again the aforementioned techniques scheme: the boss on the movable claw is 2, the lamination of the stacked workpiece of a correspondence bottom, the lamination corresponding to stacked workpiece top; Correspondence is provided with 2 cover elasticity reset devices on fixed arm.
Certainly, in the utility model, a platform, the platform that bearing one side also is extended with corresponding movable claw is provided with the pit with the claw coupling of movable claw.Can add rivet for the lamination of stacked workpiece is the lamination riveted joint one integral body, strengthens the steadiness between the whole lamination.
Operation principle of the present utility model is: drive movable claw and press to stacked workpiece when cylinder inwardly bounces back, the boss of movable claw contacts with the lamination of stacked workpiece and exerts pressure stacked workpiece is moved to the same direction of movable claw at this moment, stacked workpiece movement also drives moving of rivet, thereby whole stacked workpiece is moved.Meanwhile, the stacked workpiece that moves acts on the last sideboard and following sideboard of middle boss, and then compression reseting spring moves to the same direction of movable claw.On the other hand, the part that middle boss face contacts with stacked workpiece will produce a reaction force to the right.Therefore, it is many to the shearing idol that whole clamping always is shaped as, and causes lamination and rivet in the stacked workpiece to form a relatively-stationary integral body, so just reached the purpose that clamps and locate, and realizes required workpiece transportation.Similarly, when grasping mechanism arrives the station that stacked workpiece is discharged in transmission, cylinder outwards advances movable claw, above-mentioned active force is disappeared, go up simultaneously sideboard and following sideboard under the effect of back-moving spring, it is fair mutually to be reset to the face of middle boss, at this moment, clamps assembly and opens fully.Certainly, in the utility model, this grasping mechanism can move up under the control of other auxiliary bodies, makes the translation of some distances then, enters the next do action that grasps.
Grasping mechanism of the present utility model can reach once and to clamp the result that action can realize that lamination in the workpiece and rivet are located simultaneously, like this in the overall process of extracting, location, transmission, blowing, contrast other frame mode, some " unnecessary operations " have been saved, novel on the structure, simplified complicated structure again.Thereby can realize miniaturization and improve mechanical efficient.
