Description

Guide mould for rolling bearing

The utility model relates to a kind of column member for motion provides guiding, and the rolling bearing guided mode of guiding usefulness particularly is provided for cutter for same during the parts with holes of machining high-precision.

The cutter that is processed as of parts high accurate hole leads, known employing be that one or more fixed guide pin bushing is fitted in guided mode on the refining template (as drill jig, reaming mould, hinge mould etc.), though it can satisfy the general orientation requirement, but when cutter rotates, serious between cutter and the guide pin bushing owing to circumferentially rubbing, cause the very fast forfeiture of guided mode guiding accuracy, therefore cutter has also aggravated wearing and tearing; For addressing this problem, occurred on refining template scarf again and had one or more whirligigs (to slide or the axis of rolling is made supporting, guide pin bushing be embedded in the supporting endoporus on) guided mode, when cutter rotates, driving guide pin bushing rotates synchronously, solved the problem of above-mentioned existence, yet having what holes just need join what whirligigs on the processed parts supports, this in application, compare the former seem very uneconomical, especially a lot of and pitch of holes of hole count is hour on processed parts, because himself structure is cun bigger to the greatest extent, cause after its combination pitch of holes much larger than the pitch of holes of work piece, thereby make it to use several nothings may, these are the known guided mode of this two class and deposit so far main cause just; This two classes guided mode since guide pin bushing or whirligig all be fitted on fixing each hole of template of centre-to-centre spacing, so can only a mould one usefulness, a mould one preface, be difficult to accomplish generalization.

The purpose of this utility model is to provide a kind of for machine adds the rolling bearing guided mode that cutter leads, and it can solve the difficult problem of one module multiple usages, the many prefaces of a mould.

The purpose of this utility model is achieved in that it is by on a template, layout also constitutes with the fixing one or more guided mode unit of mechanical system, the guided mode unit is made up of lasso and hollow roller, identical and the internal diameter of external diameter (being used for guiding) is different respectively organizes roller and is in lasso and intersects the uniform and roller of five equilibrium and radially reach and circumferentially all be tight contact condition, because the roller internal diameter kind of adorning is counted difference in the lasso of guided mode unit, and roller can be done circumferentially to move to adjust required orientation along the lasso raceway, so it is identical to adapt to hole group switching centre circular diameter, and the aperture difference, the guiding of the various parts processing that five equilibrium is different needs, and can adapt to the requirement that hole group multiple operation is processed, thereby play one module multiple usages, the effect of the many prefaces of one mould; The subsidiary assembly of changing in guided mode unit, even with different inner rings and the inner assembly of roller composition and the outer ring interworking of guided mode unit, perhaps with different outer rings and the outer assembly of roller composition and the inner ring interworking of guided mode unit, it is different then can to form the guided mode center circle diameter, the roller internal diameter and plant that number, roller number have nothing in common with each other in addition to planting new guided mode unit, its scope of application is further enlarged, add that guided mode unit layout on template is various, cause unitized purpose to be achieved.Before guided mode comes into operation, at first use cubing and proofread and correct, adjust the centre-to-centre spacing between each guided mode unit, need not to adjust for the layout person of joining between the guided mode unit, by self external diameter assurance, after the adjustment, a lasso is fixed tightly on the template with mechanical systems such as end face compress, thereby each guided mode whole unit position is located, rotate the non-orientation that tightens up the lasso driven roller and make it to go to requirement of guided mode unit then, the alignment pin that at least one and peripheral parts are affixed insert wouldn't endoporus as the roller of guiding in, so far setting finishes, and can come into operation.The ferrule arrangement of guided mode unit (is used for assembling for having breach, last several roller is to clamp-on in the breach corresponding position of inside and outside lasso) folk art term limit structure ring-type physical member, also can adopt the physical member of the two rib structures that have breach and the various flange of tool, flange-type, perhaps adopt the sub-assembly that press-fits of not notched single block border physical member and various flange, flange-type stamping parts, at this moment flange, flange except that be used for the connecting, locate of template and peripheral parts, the effect of a rib of having held concurrently.Lasso raceway and roller outer diameter are straight edge line, also can select any design of the practicality combination of drop centre type, middle convex, arc slope type certainly for use.

The utility model is highly versatile not only, and when the particular topology that adopts the guided mode unit, alignment placement as shown in Figure 4, can reach the stepless adjustable purpose of capable row roller pilot hole spacing, and the circumferential layout of the guided mode unit shown in the accompanying drawing 5 can realize that roller pilot hole group switching centre circular diameter is stepless adjustable; Again because in each guided mode unit, adjacent two roller centre are apart from only being subjected to the restriction of roller wall thickness except that the internal diameter as guiding, so processing is led when being specially adapted to pitch of holes than gadget, these all known guided modes are difficult to realize.In addition, the roller internal diameter of this guided mode unit is when guiding, when cutter rotates, drive the roller original position and do synchronous rotation, and drive the circumferentially rotation of non-fastening lasso do, do not rub so have circumferentially between cutter and roller internal diameter, thereby can prolong the service life of guided mode, hold concurrently and to improve by the durability of guiding element; As previously mentioned, roller radially reaches in lasso and circumferentially all is tight contact condition, be that the zero clearance contacts to positional precision during with high supporting rigidity promptly when requiring ultra-high conducting, when requiring high guiding positional precision with the superelevation supporting rigidity is that little interference contacts, when guiding positional precision and supporting rigidity are contacting at random of microgap when normally requiring, this design itself, except that can satisfying the requirement of guiding rigidity, the guiding positional precision only is subjected to the influence of several simple constituent part manufacturings and assembly precision, can reduce to greatest extent as known guided mode because of forming the bigger accumulated error source that link causes more, so guiding positional precision height.
