Abstract
The utility model provides a screw wafting structure. Multiple screws can be effectively prevented from being blown into a designated conveying passage simultaneously, blockage of the passage is avoided, and normality in operation of an automatic screw striking machine is guaranteed. The screw wafting structure is characterized by comprising a fixing seat provided with a screw access through hole connected with a screw moving groove, rotatable elastic shifting claws are arranged on two sides of the screw access through hole respectively, one end of each elastic shifting claw corresponds to the screw moving groove while the other end of each elastic shifting claw is connected with a connecting rod in connection with an air cylinder piston rod, and a blowing device is arranged at the upper end of the screw access through hole.
Description
Technical field
The utility model relates to the manufacturing field of mechanics of communication core component, is specially a kind of screw and blows structure.
Background technology
There is a large amount of screws to fix on the communication cartridge, accomplishes to occur leaking by manual work and twist the unequal problem of the power of screwing; And production efficiency is lower; Adopt automatic screw fixing machine, screw is to rely on the method for blowing to be blown into screw in the transfer passage of appointment, but can only be blown into a screw in the transfer passage of appointment at every turn; Because the fugitiveness of blowing; Might have in the transfer passage that many screws are blown into appointment simultaneously, the obstruction of passage occur, influence the normal operation of automatic screw fixing machine.
Summary of the invention
To the problems referred to above, the utility model provides a kind of screw to blow structure, can prevent effectively that many screws are blown in the transfer passage of appointment simultaneously, has avoided the obstruction of passage, has guaranteed the normal operation of automatic screw fixing machine.
Its technical scheme is such, and a kind of screw blows structure, it is characterized in that: it comprises permanent seat; Said permanent seat is provided with screw discrepancy through hole, and said screw discrepancy through hole connects the screw movement slots, and said screw discrepancy through hole is respectively arranged with rotating resilient fingers on the both sides; The corresponding said screw movement slots of one end of said resilient fingers; The other end connects connecting rod, and said connecting rod connects cylinder piston rod, and said screw discrepancy through hole upper end is provided with blowning installation.
It is further characterized in that: said cylinder is fixed on the said permanent seat; Said resilient fingers connects through pin respectively.
In the said structure of the utility model, because permanent seat is provided with screw discrepancy through hole, screw discrepancy through hole connects the screw movement slots; Screw discrepancy through hole is respectively arranged with rotating resilient fingers on the both sides; The corresponding screw movement slots of one end of resilient fingers, the other end connects connecting rod, and connecting rod connects cylinder piston rod; Screw discrepancy through hole upper end is provided with blowning installation; Thereby the motion drivening rod through piston rod drives screw in back that resilient fingers grasps preparatory acceptance air blowing screw, when blowning installation blows preparatory acceptance air blowing screw, has stoped the screw of back to get in the screw discrepancy through hole.
Description of drawings
Fig. 1 blows the front view of structure for the utility model screw;
Fig. 2 is the upward view of Fig. 1;
The front view when resilient fingers that Fig. 3 blows structure for the utility model screw is closed up.
The specific embodiment
See Fig. 1, Fig. 2, a kind of work piece positioning locking structure of Fig. 3; It comprises permanent seat 1, and permanent seat is provided with screw discrepancy through hole 2, and screw discrepancy through hole 2 connects screw movement slots 3; Screw discrepancy through hole is provided with rotating resilient fingers 4-1,4-2 through pin 12-1,12-2 respectively on 2 both sides; The corresponding said screw movement slots 3 of the end of resilient fingers 4-1,4-2, the other end connects connecting rod 5, and connecting rod 5 connects cylinder piston rod 6; Cylinder 9 is fixed on the permanent seat 1, and screw discrepancy through hole 2 upper ends are provided with blowning installation 7.
The principle of work of the utility model work piece positioning locking structure is described in conjunction with Fig. 1, Fig. 2:
The orderly screw of arrangement is delivered on the screw movement slots 3, when first screw 8 moves to screw discrepancy through hole 2 upper ends, through control system; Cylinder 9 work; Thereby the motion drivening rod of cylinder piston rod 65 drive resilient fingers 4-1,4-2 grasp a screw 10 of first screw 8 back, have stoped the screw of back to get in the screw discrepancy through hole 2, blow out first screw 8 screw from dropping out mouth 11; Get in the transfer passage of appointment; Prevent that effectively many screws are blown in the transfer passage of appointment simultaneously, avoided the obstruction of passage, guaranteed the normal operation of automatic screw fixing machine.
Claims (3)
