Abstract
A vertical post composite guide rail structure of a vertical machining centre matches with a vertical post so that the vertical post can move on a body of a machine tool. The vertical post composite guide rail structure is characterized in that a sliding guide rail working surface and a rolling guide rail working surface are arranged in parallel on one lateral side of the vertical post corresponding to a guide rail of the body of the machine tool. A sliding guide rail and a rolling guide rail are respectively arranged on the sliding guide rail working surface and the rolling guide rail working surface of the vertical post corresponding to the guide rail of the body of the machine tool. The sliding guide rail and the sliding guide rail working surface of the vertical post form a sliding pair. The sliding guide rail working surface of the vertical post is installed in the rolling guide rail of the body of the machine tool in sliding mode through a linear sliding rail block. The vertical post composite guide rail structure adopts a composite guide rail combined by the sliding guide rail and the rolling guide rail, is capable of maintaining high feed speed by matching between the rolling guide rail and the linear sliding rail block when the machine tool is in a state of fast feed or light cut, meets the requirement of the machine tool for high speed operation. When the machine tool is in a state of heavy cut, the sliding guide rail serves as a main bearing surface of stress, and bearing capacity of the sliding guide rail is enlarged so that the vertical post composite guide rail structure meets the requirement of the machine tool for heavy cut.
Description
Technical field
The utility model relates to machine tooling equipment, particularly vertical machining centre column composite guide rail structure.
Background technology
Along with the high speed development of the high speed development of China's economic, particularly high-speed railway, large-scale wind electricity equipment, homemade big aircraft project, large ocean equipment and auto manufacturing and engineering machinery, the demand of high-precision vertical machining centre is strengthened day by day.
Column is as the vitals of vertical machining centre, the sliding pair that its guide rail is made up of two relative movement part faying faces.Guide rail is the important kinematic pair of lathe, determines rigidity, precision and the precision stability of lathe to a great extent, is one of greatest factor that guarantees machine finish.
The guide rail that modern Digit Control Machine Tool uses mainly contains three kinds: rail plate, rolling guide, hydrostatic slideway.
Rail plate has simple in structure, and the guide pass bearing capacity is big, and advantages such as good rigidity are subjected to extensive use at present, but in order to guarantee the gap between guide pass, needs artificial scraping, and workload is big; Through operation for a long time, the gap can increase, and can lower guiding accuracy simultaneously.
Rolling guide has the motion light and flexible, and dynamic and static coefficient of friction difference is little, is not prone to creeping phenomenon during low speed, but because contact-making surface is some contact or line contact, and shock resistance is poor, contact stress is big, requires very high to guide rail and rolling element.
The hydrostatic slideway advantage is obvious, but its complex structure needs a cover oil supply system, and is high to the cleannes requirement of lubricating oil, whole cost height, maintenance difficult.
Summary of the invention
The purpose of this utility model is to design a kind of vertical machining centre column composite guide rail structure, adopts the composite guide rails of rail plate and rolling guide combination, possesses the characteristic of high speed, high-mechanic, satisfy modern machine to speed and performance demands.
For achieving the above object, the technical solution adopted in the utility model is:
Vertical machining centre column composite guide rail structure can move on bed piece to cooperate column, it is characterized in that, rail plate working face and rolling guide working face be arranged in parallel on the side of the corresponding bed piece upper rail of described column; The rail plate working face and the rolling guide working face of the corresponding column of the guide rail on the described bed piece are provided with rail plate and rolling guide respectively; Described rail plate and column rail plate working face are formed sliding pair; Described column rolling guide working face is slidedly arranged on rolling guide on the lathe bed by the linear slide rail piece.
Further, described rail plate and rolling guide be arranged in parallel respectively at least two, and accordingly, corresponding rail plate working face and rolling guide working face be arranged in parallel on the described column.
The positive integer that described rail plate and rolling guide are provided with two or two respectively doubly, and parallel respectively being symmetrical arranged on the lathe bed, accordingly, parallel corresponding rail plate working face and the rolling guide working face of being symmetrical arranged on the described column.
In addition, described rolling guide is a roller line rail.
Described rail plate adopts steel guide rail, is the hardened steel guide rail below, is laminating steel guide rail above.
Advantage of the present utility model is:
1) the secondary composite guide rails that adopts linear guides and hard rail combination of the utility model column feeding guide rail;
2) composite guide rails effect face width, bearing capacity is big, the rigidity height; The secondary friction mode of original friction mode that change of composite guide rails for rolling and sliding and mutually combine, frictional force reduces, and the guide precision retentivity is good;
3) the composite guide rails dynamic response is fast, and no creeping phenomenon has not only improved the dynamic property of lathe, and has improved the machining accuracy of lathe.

Fig. 1 is the structural representation of the novel embodiment of this reality.
Fig. 2 is the novel guide rail structure A of this a reality portion enlarged diagram.
The specific embodiment
Referring to Fig. 1, Fig. 2, vertical machining centre column composite guide rail structure of the present utility model, can be in bed piece 1 motion with cooperation column 2, rail plate working face 21 and rolling guide working face 22 be arranged in parallel on the side of described column 2 corresponding bed piece 1 upper rails; The rail plate working face 21 and the rolling guide working face 22 of the corresponding column 2 of the guide rail on the described bed piece 2 are provided with rail plate 3 and rolling guide 4 respectively; Described rail plate 3 is formed sliding pair with column rail plate working face; Described column 2 rolling guide working faces 22 are slidedly arranged on rolling guide 3 on the lathe bed 1 by linear slide rail piece 5.
In the present embodiment, described rail plate 3 is symmetrical arranged two with rolling guide 4 is parallel respectively, and accordingly, corresponding rail plate working face and rolling guide working face be arranged in parallel on the described column 2.
In addition, described rolling guide is a roller line rail.Described rail plate adopts steel guide rail, is the hardened steel guide rail below, is laminating steel guide rail above.
When lathe is in fast feed or light cut, be slidedly arranged on rolling guide 3 on the lathe bed 1 by column 2 rolling guide working faces 22 by linear slide rail piece 5, can keep very high feed speed, satisfy the requirement of lathe high speed.
When lathe was in heavy cut, column rail plate working face 21 cooperated rail plate 3 as stressed main supporting surface, and bearing capacity strengthens, and satisfies the requirement of lathe heavy cut.
The utility model utilizes rail plate and the compound guide rail pattern of rolling guide, not only can satisfy at a high speed but also can realize the heavy duty cutting, and both cooperatively interact, and make machine tool capability be in optimum state.
