Abstract

The utility model relates to guide rails for a machine tool, which comprise rolling guiding moving guide rails installed on slide surfaces of both sides of a machine tool body and a big trailing board, and on slide surfaces of both sides of the big trailing board and an upper trailing board. Each of the rolling guiding moving guide rails is composed of a fixed guide rail and a rolling guide rail. Two pairs of fixed guide rails are respectively fixed to both sides of the upper plane of the machine tool body, and to both sides of the upper plane of the big trailing board. The two pairs of rolling guide rails are respectively fixed to both sides of the plane of the inner bottom of the big trailing board, and to both sides of the plane of the inner bottom of the upper trailing board. One of the rolling guide rails is fixed, and other one of the rolling guide rails is adjustable. Obliquely inlaid strips are arranged between the adjustable rolling guide rail and the plane of the inner bottom of the big trailing board, and between the adjustable rolling guide rail and the plane of the inner bottom of the upper trailing board. The big trailing board and the upper trailing board are provided with adjusting screws corresponding to the obliquely inlaid strips. The utility model has the advantages of easy adjustment, time saving, high adjusting precision and long service life.

Description

A kind of guide rail of lathe

Technical field

The utility model relates to a kind of parts of lathe, particularly a kind of guide rail of lathe.

Background technology

In the prior art, the lathe bed of lathe is provided with guide rail, vertically moves for saddle, and saddle is provided with guide rail, keeps supplying planker and laterally moves.Usually guide rail and lathe bed or saddle are that integrally casting processes, and after using a period of time, guide rail can wear and tear, and causes machining accuracy error to occur, and heavy wear also can make lathe use.If it is very big to repair difficulty, the production of using producer is brought influence.

No. 02260472.3 patent disclosure of China a kind of " roll guiding machine tool guideway ", the both sides sliding surface of its fuselage guide rail and saddle, saddle and last planker is provided with the rolling friction part, this rolling friction part comprises 2 fixing fixed guides, article 2, be provided with rolling element in the rolling guide that slides of relative fixed guide rail, the every pair of rolling guide and fixed guide by the relative isolation of retainer.Its rolling guide is fixed, and another is adjustable, connects into adjustable gaps by set screw and connects, and it is fastening by screw to regulate the back.It utilizes set screw to connect into the adjustable gaps connection, the adjusting in gap is realized by set screw, each set screw is difficult to consistent to the adjusting pressure of rolling guide when causing adjusting, friction to this rolling guide is also inhomogeneous, influence its serviceability and service life, need during adjusting slowly to regulate, consuming time many, weak effect.

Summary of the invention

The purpose of this utility model is to provide a kind of guide rail of lathe, and it can adjust the position of rolling guide easily.

The purpose of this utility model is achieved in that the guide rail of lathe comprises the rolling guiding moving guide rail on the both sides sliding surface that is installed in lathe bed and saddle, saddle and last planker, it is made up of fixed guide and rolling guide, and two pairs of fixed guides are separately fixed at both sides, plane on plane on the lathe bed, the saddle; Two pairs of rolling guides are separately fixed at baseplane in the saddle, go up both sides, baseplane in the planker; Wherein a rolling guide is fixed, another rolling guide is adjustable, it is characterized in that baseplane in adjustable rolling guide and the saddle, go up in the planker and be provided with oblique panel between the baseplane, saddle, go up planker and be provided with and the oblique corresponding set screw of panel.

The utility model adjustable rail plate and saddle inner plane, on be provided with oblique panel between the planker inner plane, saddle, last planker are provided with and the oblique corresponding set screw of panel, utilize oblique panel to regulate the gap of rolling guide, degree of regulation height, rigidity height, life-span are long, utilize set screw to regulate oblique panel, can reach degree of regulation fast, easy to adjust, save time.

Description of drawings

Fig. 1: the utility model most preferred embodiment structural representation.

Fig. 2: the oblique panel of the utility model most preferred embodiment and the assembly structure figure of set screw.

The specific embodiment

In conjunction with above-mentioned accompanying drawing the utility model is elaborated.

According to machine tool guideway shown in Figure 1, comprise the rolling guiding moving guide rail (8,9) on the both sides sliding surface that is installed in lathe bed (1) and saddle (4), saddle (4) and last planker (7), it is made up of fixed guide (8) and rolling guide (9), 2 pairs of fixed guides (8) are separately fixed at lathe bed (1), and upward plane, saddle (4) are gone up the plane, upward planker (7) is gone up the both sides, plane, and 2 pairs of rolling guides (9) are separately fixed at the interior baseplane of saddle (4), go up both sides, the interior baseplane of planker (7); Wherein 1 rolling guide is fixed, another rolling guide is adjustable, be provided with oblique panel (2,6) between adjustable rolling guide (9) and the interior baseplane of saddle (4), the last interior baseplane of planker (7), saddle (4), last planker (7) are provided with and the oblique corresponding set screw (3,5) of panel (2,6).Tiltedly the inclined-plane of panel (2,6) matches with saddle (4), last planker (7), and tiltedly match with rail plate in the plane of panel (2,6).When regulating, directly rotate set screw (3,5), can regulate oblique panel (2,6) and move forward and backward, because the ramp effect of oblique panel (2,6) has changed the position of oblique panel (2,6), thereby realize adjusting easily the position of rolling guide (9).

Claims

1, a kind of guide rail of lathe, comprise the rolling guiding moving guide rail (8,9) on the both sides sliding surface that is installed in lathe bed (1) and saddle (4), saddle (4) and last planker (7), it is made up of fixed guide (8) and rolling guide (9), two pairs of fixed guides (8) are separately fixed at lathe bed (1) and go up upward both sides, plane of plane, saddle (4), and two pairs of rolling guides (9) are separately fixed at the interior baseplane of saddle (4), go up both sides, the interior baseplane of planker (7); Wherein a rolling guide is fixed, another rolling guide is adjustable, it is characterized in that being provided with oblique panel (2,6) between adjustable rolling guide (9) and the interior baseplane of saddle (4), the last interior baseplane of planker (7), saddle (4), last planker (7) are provided with and the oblique corresponding set screw of panel (2,6) (3,5).
