Heavy-duty linear guidance system for injection molding machines, includes system of support blocks for selective control of rotational degrees of freedom and compliance

摘要

The support structure (2) is itself supported rigidly in the loading direction (G) on three bearing blocks (4.1, 4.2) carried on bearings, to follow different guide tracks (1.1, 1.2). Support structure has rotational degrees of freedom (a, b, c). Further support is provided in two directions at right angles to the direction of loading (G) and the longitudinal track direction (x). Further blocks (4.3) accommodate loading (G) compliantly and permit movement in the remaining degrees of freedom (a, b, c, y) on the guide tracks. Both of the first blocks (4.1) are carried on the same guide rail (1.1). The three blocks (4.1, 4.2) with high rigidity in the loading direction (G), are constructed for height adjustment. The three blocks (4.1, 4.2) which are highly rigid in the direction of loading, have limited movement in this direction. Guide tracks (1) are adjustable relative to each other.
