Изобретение относитс к станкостроению .FIELD: machine tool industry.
Известны цилиндрические направл ющие дл металлорежущего станка, включающие установленные на станине станка параллельно друг другу цилиндрические скалки, на которых установлен с возможностью перемещени на опорах суппорт, причем один конец каждой скалки жестко закреплен на станине 1.Cylindrical guides for a metal cutting machine are known, including cylindrical rolling pins installed parallel to each other on a machine bed, on which a support is mounted for movement on supports, with one end of each rolling pin being rigidly fixed on frame 1.
Недостатком известных направл ющий вл етс то, что скалки с обеих сторон жестко закреплены в станине станка, это не позвол ет компенсировать их тепловое удлинение и, как следствие, ведет к снижению точности станка.A disadvantage of the known guide is that the rolling pins on both sides are rigidly fixed in the frame of the machine, this does not allow compensating for their thermal elongation and, as a result, leads to a decrease in the accuracy of the machine.
Цель изобретени - повьшение точности станка путем обеспечени компенсаций теплового удлинени направл ющих.The purpose of the invention is to increase the accuracy of the machine by compensating for the thermal elongation of the guides.
Дл достижени поставленной цели второй конец каждой скалки закреплен на станине с помощью двух мембран, жестко прикрепленных с одной стороны к станине, а с другой - к скалке, при этом между мембранами установлена распорна втулка.To achieve this goal, the second end of each rolling pin is fixed on the frame by means of two membranes rigidly attached on one side to the frame, and on the other to the rolling pin, with a spacer installed between the membranes.
На фиг. 1 показано крепление цилиндрических направл ющих скалок к станине; на фиг. 2 - разрез А-А фиг. 1; на фиг. 3 - узел I фиг. 1; на фиг. 4 - узел II фиг. 1; на фиг. 5 - разрез Б-Б фиг. 4.FIG. 1 shows the attachment of cylindrical guide skalok to the frame; in fig. 2 - section A-A of FIG. one; in fig. 3 - node I of FIG. one; in fig. 4 - node II of FIG. one; in fig. 5 is a section BB of FIG. four.
К левой части станины 1 присоединены крбнШтёйнЫ-Клеммы 2 и 3. В отверсти х кронштейнов закреплены концы цилиндрических направл ющих скалок 4 и 5. Жесткое крепление скалок осуществл етс клеммами-зажимами при помощи винтов 6. К правой части станины прикреплены кронштейны 7 и 8. Сквозь отверсти этих кронштейнов пропущены вторые концы скалок 4The left part of the frame 1 is attached to the armatureSteel-terminals 2 and 3. The ends of the cylindrical guide skalons 4 and 5 are fixed in the holes of the brackets. The fixed attachment of the skalok is carried out using clamp terminals with screws 6. The brackets 7 and 8 are attached to the right part of the frame. Through the holes of these brackets missed the second ends of the skalok 4
и 5, каждь1й из которых несет по две дисковые Металлические мембраны 9. разделенные распОрйой втулкой 10 и ст нутые в осевом направлении винтом И через обеспечивающую посто нный нат г пружину 12.and 5, each of which bears two disk Metallic membranes 9 each. Separated by a separate sleeve 10 and axially mounted with an And screw through a spring 12 providing a constant tension.
Мембраны 9 выполнены с отверсти ми дл йовышений их осевой податливости и крей тс к торцам кронштейнов винтами 13. Рассто йие между мембранами определ етс расчетно, исход из услови обеспечени The membranes 9 are made with openings to increase their axial compliance and the ridge to the ends of the brackets with screws 13. The distance between the membranes is determined by calculation, based on the condition
минимальных изгибных деформаций от нагрузок в рабочем пролете скалки.minimum bending deformations from loads in the working span of the rolling pin.
При перемещении рабочего органа, например суппорта, по скалкам 4 и 5 описанное выше крепление скалок обеспечиваетWhen moving the working body, such as a caliper, on rolling pins 4 and 5, the above described rolling pin provides
высокую жесткость системы на изгиб, соответствующее схеме нагружени трехопорной двухпролетной неразрезной балки с одним закрепленным (в опоре на левом кронштейне) концом, температурное удлинение скалок, возникающее в процессе работы , компенсируетс путем осевого смещени правых концов скалок за счет прогиба мембран 9, посредством которых скалки 4 и 5 креп тс к правым кронштейнам 7 и 8.high bending system stiffness corresponding to the loading pattern of a three-support double-span continuous beam with one fixed end (in support on the left bracket), the temperature elongation of the rollers arising during operation is compensated for by axial displacement of the right ends of the rollers due to deflection of the membranes 9, by means of which the rolling pin 4 and 5 are fastened to the right brackets 7 and 8.
