Description

A kind of manipulator grasping mechanism of full automatic spring coiling machine

Technical field:

The utility model belongs to a kind of spring processing device that is used for mattress production, is specifically related to the material grasping device of the feeding mechanical hand on a kind of full automatic spring coiling machine.

Background technology:

The production of traditional double volute spring is finished by three process, first procedure is that spring, the second operation work of producing not knotting by special spring coiling machine are by special knot tying machine both ends of the spring to be tied a knot, then by manually spring rows is put well, three process is that the spring after the knotting is heat-treated.The material that the per pass operation processes in existing apparatus has plenty of manual transmission to the transmission of next procedure, the automatic feeding complex structure that has, and the action of pick-and-place material is unreliable, and inefficiency has influenced automatic feeding function.

Summary of the invention:

The technical problems to be solved in the utility model provides a kind of manipulator grasping mechanism that can fast, reliably finish the full automatic spring coiling machine of material grasping blowing action.

The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with tubulose arm connecting rod (9), it is characterized in that: the slide bar (5) that back-moving spring (8) are housed vertically passes arm connecting rod (9) with being slidingly matched, slide bar rear end and power part are in transmission connection, described arm connecting rod (9) front end is fixed with mechanical finger (11), the mechanical finger front end has and refers to hook slot (11h), accompany movingly therebetween and refer to hook (13), refer to that hook rear end and slide bar (5) are hinged, the pilot pin (14) of crosswise fixed on mechanical finger passes the oblique gathering sill (13c) that refers to that hook (13) upward is provided with movingly, and the mechanical finger front end also is provided with and the spring clamping slot (11e) that refers to hook slot (11h) approximate vertical.

Operation principle of the present utility model is: the slot (11e) of mechanical finger (11) front end is used for clamp springs (15), generally, the finger hook (13) that is contained in the finger hook slot (11h) vertical with spring clamping slot (11e) hooks spring (referring to Fig. 3 a) backward under the effect of back-moving spring (8), this moment, manipulator can be delivered to next processing stations with the clamp springs that hooks, when slide bar (5) under the promotion of rear end power part during to front slide, the finger hook (13) hinged with the slide bar front end also travels forward, the pilot pin (14) that is fixed on the mechanical finger acts on the oblique guide groove (13c) that refers on the hook, make and refer to oblique the opening of hook (13), decontrol spring (referring to Fig. 3 d), but this moment retracting spring, after putting into new spring in this state, the power of slide bar (5) rear end discharges, slide bar resets under the effect of back-moving spring (8) backward, refer to that hook (13) retreats thereupon, and under the effect of pilot pin (14), close up (a) referring to Fig. 3 to central axis, again hook the spring (15) that is clamped in the mechanical finger front end slot (11e), manipulator can be delivered to new processing stations with the clamp springs that hooks.

The utility model can cooperate the wind spring of full automatic spring coiling machine, knotting, other different institutions such as heat treatment coordinates to finish each operation of wind spring processing: the knotting station is delivered in rolled spring taking-up tied a knot, to play the spring that finishes again delivers to heat treatment mechanism and heat-treats, with the spring marshalling, can improve the operating efficiency that wind spring is produced greatly at last.The utility model also has rational in infrastructure, quick, the reliable advantage of material grasping.
