variable pitch device

Abstract

The application relates to the technical field of automation production, in particular to a variable distance device. The variable distance device comprises a supporting assembly, a plurality of load assemblies, a plurality of first pushing pieces, a plurality of second pushing pieces, two fixed limit pieces and a driving assembly. Each load assembly comprises a load piece for carrying workpieces, the load piece is slidingly connected to the supporting assembly, the plurality of first pushing pieces are arranged at one side of the load piece at intervals, the plurality of second pushing pieces are arranged at the other side of the load piece at intervals, the plurality of first pushing pieces and the plurality of second pushing pieces are arranged in a staggered manner respectively, and the two fixed limit pieces are arranged at two ends of the load piece respectively. The driving assembly is connected to the supporting assembly and is drivingly connected with the plurality of load assemblies. The driving assembly is configured to drive the plurality of load assemblies to reciprocate between a first position and a second position, so as to drive the plurality of workpieces to move away from or close to each other. The variable distance device can change the distance of the plurality of workpieces and position the workpieces, has a simple structure, low production cost and high work efficiency.
