Abstract
The invention discloses a polygonal roller pin guide mechanism. The polygonal roller pin guide mechanism comprises a guide post and a guide sleeve. The cross section of the guide post is polygonal. The cross section of an inner hole of the guide sleeve is of a polygonal structure matched with the guide post. The polygonal roller pin guide mechanism further comprises a polygonal support which is arranged between the guide post and the guide sleeve in a sleeving mode and corresponds to the shape of the guide post. A plurality of roller pins rolling in the direction of a central shaft of the guide post are arranged on each side face of the support. The roller pins abut against the outer side face of the guide post and the inner side face of the guide sleeve in a rotational mode. The polygonal roller pin guide mechanism has the advantages of being high in guide precision and long in service life.
Description
Technical field
The present invention relates to a kind of guiding mechanism, particularly relate to that a kind of guiding accuracy is high, the polygon needle roller guiding mechanism of long service life.
Background technology
On existing stamping machine, usually can arrange a guiding mechanism on punch die, this guiding mechanism generally comprises circular guide pillar and and is socketed on circular guide pin bushing outside guide pillar, and two all realize guiding by relative sliding; When punch die is to product punching press, avoid punch die to offset in the process moved down by the guiding of this guiding mechanism, thus ensure the accuracy of punch die location; Existing guiding mechanism can meet common punching production requirement substantially.
But, in lithium battery processing, copper thickness in lithium battery is thin, very high to requirement on machining accuracy, burr can not be produced in trimming or punch process, otherwise easily make lithium battery short circuit or blast, if use existing guiding mechanism to produce, because the guide pillar of existing guiding mechanism is lower with the precision coordinated between guide pin bushing, also be enough to produce copper sheet have a strong impact on to the minor shifts produced during copper sheet trimming, thus cause produced lithium battery finished product to be failed, therefore, the guiding accuracy of existing guiding mechanism can not meet some production requirement.In addition, the guide pillar of existing guiding mechanism and guide pin bushing are sliding frictions, can produce wearing and tearing, reduction of service life.
Summary of the invention
The object of the present invention is to provide that a kind of guiding accuracy is high, the polygon needle roller guiding mechanism of long service life.
To achieve these goals, polygon needle roller guiding mechanism provided by the invention, comprises guide pillar and guide pin bushing, and the cross section of described guide pillar is polygon, and the cross section of the endoporus of described guide pin bushing is in the polygonized structure coordinated with described guide pillar; Described polygon needle roller guiding mechanism also comprises and is sheathed on polygon support between described guide pillar and guide pin bushing and corresponding with the shape of described guide pillar, each side of described support is equipped with the needle roller of some central axis directions along described guide pillar rolling, and described needle roller rollably contacts at the lateral surface of described guide pillar and the medial surface of described guide pin bushing.
Compared with prior art, because the present invention is by being arranged to polygonized structure by described guide pillar and described guide pin bushing, thus limit described guide pillar and the circumference of described guide pin bushing when being socketed is rotated, and then make it can only lead along the central axis direction of described guide pillar; And, by arranging a polygonal support between described guide pillar and guide pin bushing, each side of described support is made to be provided with needle roller, the rolling of described needle roller and described guide pillar and guide pin bushing is utilized to conflict, thus described guide pillar and guide pin bushing both can have been made to realize relative motion, described guide pillar and described guide pin bushing generation sliding friction can be prevented again, avoid occurring wearing and tearing; In addition, owing to not producing any gap between described needle roller and described guide pillar and guide pin bushing, therefore, can avoid the relatively described guide pin bushing of described guide pillar that small swing occurs, affect guiding accuracy.Thus, the guiding accuracy of whole polygon needle roller guiding mechanism is high, long service life.
Preferably, each side opening of described support is provided with some grooves, and described needle roller is arranged in described groove.
Particularly, two relative sidewalls of described groove are arc-shaped, and described needle roller is embedded in described groove.
Particularly, described groove arranges along the central axis direction of described guide pillar.
Preferably, the limit number of described guide pillar is 4,6 or 8.

Detailed description of the invention
For describing technology contents of the present invention, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
As shown in Figures 1 to 4, the polygon needle roller guiding mechanism 100 of the present invention comprises guide pillar 1 and guide pin bushing 2, and the cross section of described guide pillar 1 is polygonized structure, and the limit number of described guide pillar 1 can be 4,6 or 8, and the quantity that the present embodiment adopts is 6.The cross section of the endoporus 21 of described guide pin bushing 2 is in the polygonized structure coordinated with described guide pillar 1; Described polygon needle roller guiding mechanism 100 also comprises and is sheathed on polygon support 3 between described guide pillar 1 and guide pin bushing 2 and corresponding with the shape of described guide pillar 1, and each side of described support 3 is equipped with the needle roller 4 that some central axis directions along described guide pillar 1 roll; Particularly, each side of described support 3 all offers some grooves 31, and described groove 31 is arranged in a row along the central axis direction of described guide pillar 1.Two relative sidewalls of described groove 31 are convex structure 31a, and described needle roller 4 to be embedded in described groove 31 and can to roll in described groove 31; When described support 3 is socketed between described guide pillar 1 and described guide pin bushing 2, described needle roller 4 rollably contacts at the lateral surface of described guide pillar 1 and the medial surface of described guide pin bushing 2.
Compared with prior art, because the present invention is by being arranged to polygonized structure by described guide pillar 1 and described guide pin bushing 2, thus limits described guide pillar 1 and rotate with the circumference of described guide pin bushing 2 when being socketed, and then make it can only lead along the central axis direction of described guide pillar 1; And, by arranging a polygonal support 3 between described guide pillar 1 and guide pin bushing 2, each side of described support 3 is made to be provided with needle roller 4, described needle roller 4 is utilized to conflict with the rolling of described guide pillar 1 and guide pin bushing 2, thus described guide pillar 1 and guide pin bushing 2 both can have been made to realize relative motion, can prevent again described guide pillar 1 from described guide pin bushing 2, sliding friction occurring, avoid occurring wearing and tearing; In addition, owing to not producing any gap between described needle roller 4 and described guide pillar 1 and guide pin bushing 2, therefore, can avoid the relatively described guide pin bushing 2 of described guide pillar 1 that small swing occurs, affect guiding accuracy.Thus, the guiding accuracy of whole described polygon needle roller guiding mechanism 100 is high, long service life.
Above disclosedly be only preferred embodiments of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
