Abstract

The utility model provides a fixture for the circumferential multiple equal dividing and positioning of a super-long rod guide element, and discloses a fixture for precisely positioning circumferential guide elements of various large mechanical rod sleeve type parts. The fixture for the circumferential multiple equal dividing and positioning of the super-long rod guide element consists of a guide sleeve fixture and a guide column fixture, wherein the guide sleeve fixture comprises a cylindrical pipe body; at least three prisms which are equally divided and further axially arranged are arranged outside the cylindrical pipe body; the prisms are integrally arranged with the cylindrical pipe body; the prisms coincide with guide grooves of a guide sleeve; the guide column fixture comprises a round ring body; at least three recesses which are evenly distributed and further axially arranged are arranged on the inner side of the round ring body; and the recesses coincide with guide edges of a guide column. The guide sleeve and the guide column which are produced through two fixtures have good coupling effect; after the guide sleeve and the guide column are coupled, no clearance exists between the guide sleeve and the guide column; during movement, no mechanical collision is generated; the guiding is stable; and the element damages caused by the mechanical collision are prevented.

Description

The overlength rod guidance is to the many five equilibriums of element circumference location built-up jig

Technical field

The utility model discloses a kind of pinpoint anchor clamps of all kinds of big machinery bar cover parts circumference director elements that are used for.

Background technology

At present, director element adds man-hour, realizes that through location structure location structure is made up of guiding rib on the guide pillar and the guide groove on the guide pin bushing between the guide pin bushing of combination and the guide pillar each other; Prior art is relatively more difficult to the five equilibrium processing of guiding rib and guide groove, and its machining accuracy is poor, and working (machining) efficiency is low, and peripheral clearance is inhomogeneous during coupling, produces mechanical collision during motion, causes guiding unstable, and director element is fragile.

Summary of the invention

The utility model provides a kind of overlength rod guidance to the many five equilibriums of element circumference location built-up jig; Purpose is to solve existing director element location difficulty; Positioning accuracy is poor, working (machining) efficiency is low, and peripheral clearance is inhomogeneous during coupling, produces mechanical collision during motion; Cause guiding unstable, the flimsy problem of director element.

The utility model is made up of guide pin bushing anchor clamps and guide pillar anchor clamps; Said guide pin bushing anchor clamps comprise cylindrical tube; At least three that divide equally and axial arranged rib bodies are set outside said cylindrical tube, and said rib body and cylindrical tube are wholely set, and the guide groove of said rib body and guide pin bushing coincide; Said guide pillar anchor clamps comprise torus, are uniformly distributed with and axial arranged groove at least three of the inboard settings of said torus, and the guiding rib of said groove and guide pillar coincide.

The utility model is used for the circumference of five equilibrium director element; Promptly adopt the circumference of branch guide pin bushings such as guide pin bushing anchor clamps and the guide groove body is set at each equally divided position; It is external that each guide groove body is engaged in each rib, and the guide groove body is welded on the madial wall of cylindrical tube of guide pin bushing, so promptly accomplishes five equilibrium, the processing of guide pin bushing; Equally, adopt the circumference of branch guide pillar such as guide pillar anchor clamps, and the guiding rib is set in the groove of each five equilibrium, then directive wheel is welded on the lateral wall of cylindrical tube of guide pillar, so promptly accomplish five equilibrium, the processing of guide pillar; The above-mentioned mode of accomplishing five equilibrium, processing director element through anchor clamps, processing is simple, and efficient is high.

When guide pin bushing anchor clamps of the utility model and guide pillar anchor clamps use, be installed on the frock, effective through guide pin bushing and guide pillar coupling that two anchor clamps are produced; There is not the gap after the coupling between the two; Can not produce mechanical collision during motion, guiding is stable, the component wear of having avoided mechanical collision to cause.

Fig. 1 is the structural representation of the guide pillar anchor clamps of the utility model;

Fig. 2 is the structural representation of the guide pin bushing anchor clamps of the utility model.

Among the figure, 1, the guide pin bushing anchor clamps, 2, the guide pillar anchor clamps, 3, the rib body, 4, groove, 5, cylindrical tube, 6, torus, 7, guide pin bushing, 8, guide pillar, 9, guiding rib, 10, the guide groove body.

The specific embodiment

Like Fig. 1, shown in 2; This overlength rod guidance is to the many five equilibriums of element circumference location built-up jig; Be made up of guide pin bushing anchor clamps 1 and guide pillar anchor clamps 2, guide pin bushing anchor clamps 1 comprise cylindrical tube 5, and at least three that divide equally and axial arranged rib bodies 3 are set outside cylindrical tube 5; Rib body 3 is wholely set with cylindrical tube 5, and rib body 3 coincide with the guide groove of guide pin bushing 7; Guide pillar anchor clamps 2 comprise torus 6, are uniformly distributed with and axial arranged groove 4 in torus 6 at least three of inboard settings, and groove 4 coincide with the guiding rib 9 of guide pillar 8.

Claims

1. the overlength rod guidance is to the many five equilibriums of element circumference location built-up jig; It is characterized in that forming by guide pin bushing anchor clamps and guide pillar anchor clamps; Said guide pin bushing anchor clamps comprise cylindrical tube; At least three that divide equally and axial arranged rib bodies are set outside said cylindrical tube, and said rib body and cylindrical tube are wholely set, and the guide groove of said rib body and guide pin bushing coincide; Said guide pillar anchor clamps comprise torus, are uniformly distributed with and axial arranged groove at least three of the inboard settings of said torus, and the guiding rib of said groove and guide pillar coincide.
