Abstract

Predmetom vynálezu je uloženie matice pohybových skrutiek v saniach, ktoré zabezpečuje požadovaná súososť matice a skrutky. Matice pohybových skrutiek sú v bežnej praxi; pevne spojené so saňami či zosrkutkované alebo ; i Zalisované alebo vytvořené priamo v teleše saní. ; Nevýhodou tohoto spósobu je, že je nutno presne ·! s lícovat vedenie saní. Táto nevýhoda sa ešte vypukle jšie prejavuje, ked je jednou skrutkou pohybo- vaných viac ako jedny saně. ; Túto nevýhodu odstraňuje uloženie matice po; dTa vynálezu ktorého podstata spočívá v tom, že í v přesúom otvore telesa saní, ktorého os je kolmá ' na směr pohybu saní, je uložená matica o menších rozmeroch ako je přesný otvor, obmedzená v smete osi závitu dvoma rovnoběžnými plochami, právej príložky a lávej príložky, obe tvaru valcovej ; úseče, ktorých rozměr je v smere osi závitu matice i i lícovaný s maticou do přesného otvoru bez vole. Příklad konštrukčného riešenia podía vynálezu je znázorněný na pripojenom výkrese, kde obr. 1 představuje pozdížny rez uložením matice v sa- iach a obr. 2 představuje priečny rez uložením matice. Do telesa saní 2 je zhotovený přesný válcový otvor 1, ktorého os je kolmá na směr pohybu saní. Db tohoto otvoru sa vloží matica 3 taká, aby mala vo všetkých smeroch kolmých na os skrutky 7 primeránú volu a čelá vytvořené dvomi presne rovnoběžnými plochami 4. V smere osi závitu sa otvor vyplní dvoma příložkami, pravou priložkou 5 a Tavou priložkou 6, v podobě válcových úsečí, zalícovanými s maticou 3 s minimálnou volbu v smere osi skrutky 7. Tbto usporiadanie je nenáročné na výrobu a nepožaduje přesné lícovanie vedenia saní, lebo matica sa na skrutke sama ústředí vo všetkých smeroch kolmách na pmer pohybu saní a prenáša pohyb na saně vyvodeňý závitom skrutky bez vole. Výhoda tohoto riešenia sa obzvlášť prejaví na stroji, kde je jednou skrutkou pohybovaných viac saní.

An example of a construction according to the invention is shown in the attached drawing, wherein FIG. 1 shows a longitudinal section through the mounting of the nut in the figures, and FIG. 2 is a cross-sectional view of a nut mounting. A precision cylindrical opening 1 is formed in the carriage body 2, the axis of which is perpendicular to the direction of movement of the carriage. A nut 3 is inserted Db of this opening so that it has an adequate steer and face in all directions perpendicular to the screw axis 7 formed by two precisely parallel surfaces 4. In the direction of the thread axis, the hole is filled with two shims, a right attachment 5 and a Tava enclosure 6, in the form cylindrical segments, aligned with nut 3, with a minimum choice in the axis of the screw 7. This arrangement is not demanding in production and does not require precise fitting of the carriage because the nut itself in the head center in all directions perpendicular to the carriage movement and carries the movement to the carriage driven threaded bolts without dude. The advantage of this solution is especially evident in the machine where more than one carriage is moved by one screw. (Movement, eg on vices, or differential movement).

Description

; Predmetom vynálezu je uloženie matice pohybových skrutiek v saniach, ktoré zabezpečuje požadovánu súososť matice a skrutky.; It is an object of the present invention to provide a nut of a motion screw in a carriage which provides the required alignment of the nut and the screw.

Matice pohybových skrutiek sú v bežnej praxi' pevne spojené so saňami či zosrkutkované alebo ; i žalisóvané alebo vytvořené priamo v teleše saní. ; Nevýhodou tohoto spósobu je, že je nutno presne ·! 1 lícovat vedenie saní.

OBJECTS and FIG.

2 is a cross-sectional view of a nut fit.

A precision cylindrical bore 1 is made into the slide body 2, the axis of which is perpendicular to the direction of movement of the slide. Db of this hole is inserted nut 3 such that it has adequate water in all directions perpendicular to the axis of the screw 7 and the faces formed by two exactly parallel faces 4. In the direction of the thread axis, the hole is filled with two tabs, right side 5 and cylindrical sections flush with nut 3 with minimum selection in the direction of the screw axis 7.

This arrangement is easy to manufacture and does not require precise alignment of the slide guide, since the nut on the bolt itself headers in all directions perpendicular to the slide movement and transmits the movement on the slide resulting from the bolt-free bolt thread. The advantage of this solution is particularly evident on a machine where more than one slide is moved by one screw. (Movement symmetrical eg on vices or differential motion).

BACKGROUND OF THE INVENTION a slide (2) whose axis is perpendicular to the direction of movement of the slide (2), is a nut (3) of smaller dimensions than the precision bore (1), limited in the thread axis direction by two parallel faces (4) and a left cylindrical segment shaped fitting (6), the dimension of which is in the direction of the thread axis of the nut (3) aligned with the nut (3) into the precision bore (1) without clearance. ^!
