Abstract

The utility model discloses a stepped rectangular rail pair and its application on the beam part of the gantry type boring-milling machine. The upper rail front end surface and the lower rail front end surface of the stepped rectangular rail pair as the main rail are not in the same plane, a series of steps are formed between the upper rail and the lower rail, an elevation is provided between the connection line between the gravity centers of the upper rail and the lower rail and the vertical plane; the rail structure of the sliding board engaged with the main rail corresponds to the main rail, thus the stepped rectangular rail pair is formed. The plane of the sliding board suspension ram type boring and milling head is perpendicular to the workbench. The beam part of the gantry type boring and milling head having the stepped rectangular rail pair can be completed by ordinary process for the rail machining in the manufacturing process, and great manufacturability is obtained in the aspects of machining and assembling. After mounting of the ram type boring and milling head parts, component force along the close adhering surface is provided, the trend of generating forward inclination during the working of the boring and milling head is avoided, and the stability of geometrical precision is improved for the machine tool.

Description

A kind of stepped rectangular guideway pair
Technical field
The utility model relates to the guide rail structure of a kind of machining equipment and lathe, particularly relates to a kind of stepped rectangular guideway pair.Described stepped rectangular guideway pair not only can be used for the beam part of plane milling and boring machine, and can be used in other machine tool.
Background technology
The fromer rail of the common beam guideway of plane milling and boring machine (guide rail of boring and milling head outer is installed), the front end face of its upper and lower guide rail is same plane, and perpendicular to work top, its advantage is: the manufacturability of processing this beam guideway is better, the depth of parallelism requirement of its front end face and its reverse side (guide pass that matches with column) can reach by the general technology method.Shortcoming is the lathe less stable, because the crossbeam fromer rail need be hung slide carriage and ram type boring and milling head outer, ram type boring and milling head outer profile is longer, and it is heavier, the vibration that produces when the work machining has the boring and milling head outer of making to produce the trend that leans forward, thereby influences geometric precision of machine tool.
The utility model content
After being installed, the ram type boring and milling head outer should keep geometric precision of machine tool stability for solving above-mentioned guideway, reach this guideway again and have the favorable manufacturability problem aspect processing and the assembling, the utility model provides a kind of stepped rectangular guideway the secondary and application on plane milling and boring machine.
A kind of stepped rectangular guideway described in the utility model, form by main body guide rail and slide carriage, upper rail front end face that described stepped rectangular guideway is the main body guide rail and lower guideway front end face be not or not same plane, upper rail and lower guideway form certain stepped, and the line of upper rail and the stressed center of gravity of lower guideway forms certain elevation angle with vertical plane.
As a kind of improvement of the present utility model, described stepped rectangular guideway is applied on the plane milling and boring machine beam part, the guide rail structure and the beam guideway of the slide carriage that matches with beam guideway are corresponding, thereby form stepped rectangular guideway pair, hang the plane of ram type boring and milling head outer on the slide carriage then perpendicular to work top.
The plane milling and boring machine of above-mentioned stepped rectangular guideway pair is housed, and the guide rail processing in manufacture process can adopt common technology mode and metering system to finish, and has favorable manufacturability.
Beam part with plane milling and boring machine of above-mentioned stepped rectangular guideway, because the upper rail and the lower guideway of beam guideway form certain ladder, the line of the stressed center of gravity of its upper and lower guide rail is an elevation angle, after boring and milling head outer is installed, has the component that is close to binding face, what produced when having avoided the work of ram type boring and milling head outer leaning forward component and the ram type boring and milling head outer that the causes trend that leans forward, and has improved the stability of geometric precision of machine tool.
Described stepped rectangular guideway pair can be widely used in machine tool.The utility model is applied on the plane milling and boring machine beam part especially.

The specific embodiment
Embodiment 1:
As shown in Figure 1, a kind of stepped rectangular guideway described in the utility model is paid by crossbeam (8) and slide carriage (6) and is formed.Crossbeam (8) has upper rail (1) and lower guideway (9), the front end face (B) of upper rail (1) and the front end of lower guideway (9) and (D) at intervals to form its upper rail (1) and lower guideway (9) is stepped rectangular guideway.
The part that described slide carriage (6) matches with crossbeam (8) is processed into upper rail (1) and the corresponding structure of lower guideway (9) with crossbeam (8).
Its slide carriage plane (E) that boring and milling head outer (10) is installed of described slide carriage (6) is vertical plane (perpendicular to a work top).
Crossbeam (8) cooperates with the corresponding guideway of slide carriage (6), adjusts by panel (7); Crossbeam (8) is connected with slide carriage (6), uses nut (2) that pressing plate (3) is tightened, with nut (5) pressing plate (4) tightened respectively.
Ram type boring and milling head outer parts (10) by bolted on the slide carriage plane of slide carriage (6) (E).
Crossbeam (8) with ram type plane milling and boring machine of described stepped rectangular guideway, slide carriage (6) and ram type boring and milling head outer parts (10), when the machining part, operation before and after work stage is done on the one hand, boring and milling head outer is done vertical up-or-down movement along ram on the other hand, the vibration force that produces owing to cutting workpiece, the component that ram type boring and milling head outer (10) has generation to lean forward, because crossbeam (8) has the stepped rectangular guideway version of upper rail (1) and lower guideway (9), the installation of the line of the stressed center of gravity of the stressed center of gravity of upper rail (1) and lower guideway (9) and ram type boring and milling head outer (10) and formed the elevation angle of ram type boring and milling head outer (10), what produced when having avoided ram type boring and milling head outer (10) work leaning forward component and the ram type boring and milling head outer that the causes trend that leans forward, and has improved the stability of geometric precision of machine tool.
