Abstract

The utility model provides a numerical control punch AB station guide sleeve including a striking head, a gasket, a spring, a stop ring and a pin, and further including an outer cover for protecting a screw. The outer cover is arranged between the gasket and the stop ring. The numerical control punch AB station guide sleeve is additionally provided with the outer cover to protect the spring on the numerical control punch, and to prevent the fragments of a damaged spring from falling to the punch die machining parts to result in unnecessary safety hidden troubles.

Description

Numerical control press AB station guide pin bushing

Technical field

The utility model belongs to the numerical control punch die technical field, is specifically related to a kind of numerical control press AB station guide pin bushing of fast demountable drift.

Background technology

At present; Up-to-the-minute numerical control press AB station guide pin bushing is not only in elastic force that keeps product and bullet speed; And it goes back easy accessibility, but this numerical control press AB station guide pin bushing is because spring structure is exposed outside, when spring fragment when damaging can drop to the punching machine mold working position; Cause potential safety hazard, so be badly in need of now improving.

Summary of the invention

To the problems referred to above, the purpose of the utility model is to propose a kind of spring fragment when damaging that prevents can drop to the numerical control press AB station guide pin bushing that the punching machine mold working position causes potential safety hazard.

A kind of numerical control press AB station guide pin bushing, it comprises: attacking head, packing ring, screw, spring, stop ring and pin, also be provided with one be used to protect screw outer cover, said outer cover is spirally connected and is located between said packing ring and the stop ring.

Said attacking head integral body is one " T " structure, and downside is one to extending below up big and down small tapered configuration, and said attacking head top platform is provided with the gap, and the both sides, gap of said attacking head are respectively equipped with screwed hole, interlocking screw in the said screwed hole; Said packing ring is fixed on the downside tapered configuration of attacking head, and said packing ring upper end overhead is in the screw lower end; Said washer underside is provided with the spring that is socketed on the attacking head downside tapered configuration, and said spring upper end overhead is in washer underside.

Said spring lower end overhead is at the stop ring upside, and said stop ring screw fastening is connected on attacking head downside tapered configuration lower end, and said stop ring middle part is provided with through hole, wears pin in the said through hole.

The utility model has the following advantages owing to take above technical scheme:

A kind of numerical control press AB of the utility model station guide pin bushing has been set up outer cover, has protected the spring on the numerical control press, and has prevented that spring fragment when damaging from can drop to the punching machine mold working position, caused unnecessary potential safety hazard.

Description of drawings

Fig. 1 is the overall structure sketch map of a kind of numerical control press AB of the utility model station guide pin bushing.

Fig. 2 is another overall structure sketch map of a kind of numerical control press AB of the utility model station guide pin bushing.

The specific embodiment

Below in conjunction with accompanying drawing and instance the utility model is carried out detailed description.

As depicted in figs. 1 and 2; Be the overall structure sketch map of a kind of numerical control press AB of the utility model station guide pin bushing, comprise attacking head 1, packing ring 2, screw 3, spring 4, outer cover 5, stop ring 6 and pin 7 that said attacking head 1 integral body is one " T " structure; Downside is one to extending below up big and down small tapered configuration; Attacking head 1 top platform is provided with

gap

11, and 11 both sides, gap of attacking head 1 are respectively equipped with screwed hole 12, interlocking screw 3 in the screwed hole 12; Said packing ring 2 is fixed on the downside tapered configuration of attacking head 1, and packing ring 2 upper end overheads are in screw 3 lower ends; Said packing ring 2 downsides are provided with the spring 4 that is socketed on the attacking head 1 downside tapered configuration; Said spring 4 upper end overheads are at packing ring 2 downsides; Make packing ring 2 move up through spring 4, make the gap 11 at attacking head 1 top dwindle, and drift is locked at attacking head 1 top; Said spring 4 lower end overheads are at stop ring 6 upsides, and stop ring 6 screw fastenings are connected on attacking head 1 downside tapered configuration lower end, and stop ring 6 middle parts are provided with through hole, wear pin 7 in the through hole, make stop ring 6 be fixed on attacking head 1 downside tapered configuration lower end.

Be spirally connected between said packing ring 2 and the stop ring 6 and be provided with outer cover 5, cover screw 3 outsides, externally protect screw 3.

In the use, when needs dismounting drift, down twist both sides screw 3, lower gasket 2 is backed down in screw 3 lower ends, and the gap 11 of attacking head 1 flicks, and can unclamp drift.

The utility model only carries out illustrative with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of the utility model technical scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
