Abstract

The invention provides a ball linear precise transverse moving platform. The platform comprises a ball guide rail mechanism, an ejector block (13), an ejector rod base (14) and a micrometer head (15). The ball guide rail mechanism comprises a concave guide rail base (2), a convex sliding groove (1), a plurality of cylindrical shafts (10), a first holder (21), a second holder (12), a first tension spring nail (3), a second tension spring nail (7), a tension spring (4) and a plurality of balls (11); the convex sliding groove (1) is located above the concave guide rail base (2), rectangular grooves (18) are formed in the middle positions of a third rectangular groove (16) and a fourth rectangular groove (17), and the first holder (21) and the second holder (12) are inserted in the rectangular grooves (18); cylindrical shafts (10) are placed on the two sides of each of the first holder and the second holder, and the first tension spring nail (3) and the second tension spring nail (7) are arranged at the two ends of the rectangular channel, and are sleeved with the two ends of the tension spring (4).

Description

technical field [0001] The invention relates to the technical field of mechanical precision instruments and meters, in particular to a ball linear precision translation platform. Background technique [0002] At present, in precision mechanical design and mechanical manufacturing, the improvement of the movement accuracy of instruments and meters mainly depends on the processing accuracy of the instruments and meters themselves and the new and reasonable design structure. Among them, the guide rail mechanism is an important part of the linear precision translation stage, and its composition forms are various. Among them, the common guide rail forms are mainly divided into two categories: sliding guide rail mechanism and ball guide rail mechanism. [0003] Such as Figure 1-3 As shown, the common sliding guide rail mechanisms are mainly divided into dovetail guide rails, right-angle H-type guide rails and cylindrical surface guide rails. This type of guide rail mechanism ma...
