Single-shaft driver

Abstract

The invention discloses a single-shaft driver. The single-shaft driver comprises a base. A sliding block is arranged on the base. Dust-proof strips are arranged between the two sides of the sliding block and the base. Sliding block outer circulators are arranged at the front end and the rear end of the sliding block. End dust-proof iron pieces and end dust-proof pieces are sequentially arranged onthe outer sides of the two sliding block outer circulators. Sliding block inner circulators are arranged on the inner sides of the sliding block outer circulators. A reverser stop piece is arranged in the bottom of the sliding block. A first lead screw reverser is arranged in the reverser stop piece. Second lead screw reversers are arranged on the inner sides of the sliding block inner circulators. The single-shaft driver is simple in structure, external circulation is replaced with internal circulation to achieve ball circulation through the reversers, the radial size is small, and the rigidity is good; and the return distance to a rollerway is short, so that the friction loss is small; the single-shaft driver is suitable for high-sensitivity and high-precision transmission, and processing the circulating path of the main sliding block is made easy; the reversers are modularized, so that the universality of modules is greatly improved, and the cost is reduced; meanwhile, the production efficiency of the modules is greatly improved; and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of automatic processing workpiece positioning equipment, in particular to a single-axis driver. Background technique [0002] At present, most of the circulation methods of modules on the market are external circulation (bend pipe circulation). (1) The volume of external circulation products is relatively large and noisy; (2) The assembly efficiency of external circulation is low and the precision of parts is high; (3) External circulation The cycle will wear and compress the elbow during the cycle, which will reduce the life of the elbow. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a kind of uniaxial drive, comprise base, slide block is arranged on the described base, all are provided with dustproof strip between slide block two sides and base, slide block Slider outer circulators are installed at the front and rear ...
