[0006]
Another example is disclosed in Japanese Patent Publication No. 54-32888. The cross linear bearing disclosed in this publication is provided with a guide groove in which a guide base is fitted on the upper and lower surfaces of the bearing body in a direction crossing each other, and one guide guide is provided on the inner surface of the guide groove. The grooves that make up the four load rails are complemented with the rolling grooves of the load balls that have been cut off on the base, and the grooves that form the return rails of the unloaded balls are cut on both sides of the grooves.

It is. Similarly, an XY table composed of cross linear bearings in the XY directions is disclosed in Japanese Patent Publication No. 4-72084.
[0007]
Japanese Patent Publication No. 57-40372 discloses a cross linear bearing unit. The cross linear bearing unit is configured to accurately position the slidable body by linearly sliding the slidable body in the vertical direction and the horizontal direction.
[0008]
[Problems to be solved by the invention]
However, in the conventional cross linear bearing unit, in order to make the movement on a two-dimensional plane, for example, as shown in FIG. 7, on one slider 1B, 1B sliding on the track bodies 2B, 2B. A bracket or an intermediate table 26 is attached, another track body 2A, 2A is fixed to the intermediate table 26, and another slider 1A, 1A that slides on the track body 2A, 2A is provided. As described above, the conventional cross linear bearing unit requires an intermediate member such as the intermediate table 26 and the bracket. Therefore, an accumulated error occurs due to the intermediate member interposed, and high-precision mounting is difficult. The number of parts increases, the weight of the moving body increases, the inertial force increases, and the response also decreases. In addition, when the two orbital bodies 2A and 2B are orthogonal to each other, how the other orbital body 2B can be set and fixed at a right angle with respect to the one orbital body 2A. In addition, when an attachment member such as an intermediate member is fixed to another part with a bolt or the like, there is also a problem that the fixing portion is loosened due to vibration or the like generated by high-speed operation of the apparatus.
[0009]
Further, as cross linear bearings that do not use a table or a bracket, those disclosed in the above-mentioned publications are known, but these cross linear bearings are rails that extend across one bearing body (slider). A guide base (track rail) is provided and relates to relative movement in the horizontal direction, that is, in the XY direction (see Japanese Patent Publication No. 54-32888 and Japanese Patent Publication No. 4-72084). However, since these cross linear bearings are formed with guide grooves on the upper and lower sides of the slider, another track rail can be two-dimensionally moved relative to the fixed track rail. The casing that slides on the rail is not two-dimensionally planarly moved, and a support member such as a chuck cannot be provided on the casing itself. That is, the cross linear bearing has a structure in which a slide base is fixed on a pair of rails, and the other pair of rails moves integrally on one rail. Accordingly, each of the other rails cannot be moved independently. For example, even if a support member or the like is provided on each of the other rails, the respective support members cannot cooperate to grip an article. It is a structure.
[0010]
An object of the present invention is preferably applied to a relatively small apparatus such as an assembly robot, an industrial robot, a semiconductor manufacturing apparatus, an inspection apparatus, or a machine tool, and moves an object two-dimensionally from a certain position. At the same time, the intermediate table, bracket, etc. used in the prior art are not required, and at least a pair of track bodies and one slider are used to reduce the number of parts and to minimize the cumulative error between multiple parts. The weight of the moving body is reduced to reduce the weight, the inertial force is reduced to enable high-accuracy relative movement on the plane where the pair of track bodies cross each other, and a predetermined 90 ° orthogonal between the track bodies The object is to provide a composite rolling guide unit that can set the angle with high precision and can cope with high precision, high speed, small size, and light weight.
