Abstract

The utility model relates to a movable worktable comprising three rolling guide rails. Because the width of the movable worktable with three rolling guide rails is the width of the distance of a guide rail more than the movable worktable with two rolling guide rails, and the rails are the guide rails, the width of the movable worktable is increased, the heavy load, the high efficiency and the precision are achieved, and a significant guarantee is provided for the development of a numerical control machine. The movable worktable is formed by connecting a sliding base, a sliding table and the guide rails; the rolling guide rails are connected with a rolling sliding block and the sliding table perpendicular to the upper surfaces, and the lower surfaces are connected with the sliding base perpendicular to the lower surfaces; the three rolling guide rails are parallel to one another and are perpendicularly arranged between the sliding base and the sliding table; the guide rails on two sides are used for positioning guide, and the middle guide rail is used for floating support rather than the positioning guide; the distances among the three guide rails can be either equal or unequal; the rolling guide rails can adopt either ball type or roller type; and the sliding table and the sliding base can be either steel pieces or iron castings.

Description

Article three, the travelling table formed of rolling guide

Technical field: the utility model relates to the travelling table that a kind of three rolling guides are formed, and specifically being provides a kind of high-power, heavy cut, high accuracy, high efficiency travelling table for Digit Control Machine Tool.

Technical background: present machine tool, what the travelling table of Digit Control Machine Tool was general all is two guide rails, it also all is rail plate that three guide rails of minority are arranged, distance between the former two guide rails is inversely proportional to loading capacity, and the big more carrying of distance is just light more, has therefore restricted travelling table and has developed to the large-scale heavy duty direction, though the latter can be a large-scale heavy duty, but owing to it is that rail plate has restricted at a high speed, efficient direction develops, thereby becomes the bottleneck that development large-scale heavy duty, accurate direction develop.

Content of the present utility model: provide the travelling table that a kind of three rolling guides are formed, since three guide rails than the travelling table of two guide rails increased a guide rail apart from width, it is rolling linear guide in addition, increased the width of travelling table, realized heavily loaded, efficient and accurate.For the development of Digit Control Machine Tool provides important guarantee.

Its technical scheme is: it is formed by connecting by slide, guide rail, slide unit, the rolling slide rail with link to each other perpendicular to top rolling slide block, slide unit, link to each other below with perpendicular to following slide, three rolling guides are parallel to each other and vertically place between slide and the slide unit.The quantity of the rolling slide block on the rolling slide rail is decided on the length of travelling table, but must not be less than two, and the distance between three rolling guides is decided on the width of travelling table, but the distance between three rolling guides equates.Slide and slide unit can be steel parts, also can be ironcastings, and rolling guide can be a ball-type, also can be roller-types.The guide rail on both sides is positioning and guidings, and middle guide rail then is a floating support, rather than positioning and guiding.

Because having adopted such scheme, its executing agency all is some common components and parts, and simple in structure, be easy to realize, and remarkable in economical benefits.

Among the figure, 1, slide, 2, slide unit, 3, rolling slide rail, 4, rolling slide block

The specific embodiment: roll among the figure slide rail (3) with perpendicular to top rolling slide block (4), slide unit (2) links to each other, below with link to each other perpendicular to following slide (1), three rolling guides (3) are parallel to each other and vertically place between slide (1) and the slide unit (2).Rolling slide rail (3) is gone up the quantity of rolling slide block (4) and is decided on the length of travelling table, but minimumly must not be less than two.Article three, the distance between the rolling guide is decided on the width of travelling table, but the distance between three rolling guides equates, also can be unequal.Slide (1) can be a steel part with slide unit (2), also can be ironcasting, and rolling guide can be a ball-type, also can be roller-type.The guide rail on both sides is positioning and guidings, and middle guide rail then is a floating support, rather than positioning and guiding.

Claims
