Precisely position the silo

Abstract

The invention discloses an accurate positioning storage bin. The accurate positioning storage bin comprises a storage bin frame, workpiece lifting mechanisms and a workpiece horizontal rotary conveying mechanism; the workpiece horizontal rotary conveying mechanism comprises a first motor which is arranged on the storage bin frame, a rotary disc which is connected with a first motor rotor and workpiece loading mechanisms which are arranged along the peripheral direction of the rotary disc at equal intervals; and two sets of workpiece lifting mechanisms are arranged and are distributed opposite to the two sets of workpiece loading mechanisms, and each workpiece lifting mechanism comprises a clamping jaw for conveying workpieces on the workpiece loading mechanisms and a drive device for driving the clamping jaw to lift and descend. According to the accurate positioning storage bin, the first motor drives the rotary disc so as to drive the workpiece loading mechanisms to rotate horizontally, so that the transmission error existing in conventional storage bin chain wheel and chain transmission is eliminated, the repeat positioning precision along the horizontal direction is high, and a manipulator of processing equipment can accurately take and store materials; and moreover, a plurality of workpiece loading mechanisms can be arranged on the same rotary disc, the loading capacity of the storage bin is large and the storage bin occupies a small area.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a workpiece loading, conveying and positioning device. Background technique [0002] At present, the traditional and common silos include flat friction plate silos and multi-station silos. [0003] The plane friction plate type silo uses a motor to drive the sprocket, and the sprocket drives the friction plate chain to realize the horizontal transportation of the workpiece. Together to achieve vertical transport. At the same time, the workpiece is positioned on the working line by the sensor. [0004] The traditional multi-station silo also uses the motor to drive the sprocket, the sprocket drives the chain, and the chain drives the workpiece pallet fixed on it to realize the horizontal transportation of the workpiece. After the workpiece is transported to the machine tool or the material grabbing point of the manipulator, A motor drives the supporting rod to lift the workpiece to realiz...
