Four-coordinate automatic loading-unloading robot

Abstract

The invention relates to a four-coordinate automatic loading-unloading robot, comprising an upright column and cross beam unit, a robot body unit and a swing unit, wherein the upright column and cross beam unit comprises three upright columns and a cross beam; the cross beam is fixedly arranged on the upright columns through screws; a linear guide rail is arranged on the cross beam; the robot body unit comprises a sliding pillow, an X-way motor, a crank arm, a crank arm leg and a crank arm motor; the sliding pillow is arranged on the linear guide rail; the swing unit comprises a nut side motor, a nut side speed reducer, a nut, a spline nut side motor, a spline nut side speed reducer, a spline nut, a ball screw spline shaft and a small arm; under the combined action of the nut side motor and the spline nut side motor, power is transmitted to the nut and the spline nut through a nut side synchronous belt and a spline nut side synchronous belt, so that the ball screw spline shaft moves. By applying the four-coordinate robot, the rapid loading and unloading of a machine tool can be realized; therefore the clamping precision is improved, the production period is shortened, the efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of four-coordinate robots for loading and unloading, in particular to a four-coordinate robot capable of realizing automatic clamping of workpieces and fully automating loading and unloading of machine tools. Background technique [0002] In the prior art, during the processing of the workpiece by the CNC machine tool, it is necessary to load and unload the machine tool. Because the workpiece needs to be clamped many times, most of them currently use manual clamping. However, manual clamping not only has low precision, but also affects The processing quality is high, and the labor cost is high, the efficiency is low, and the production cycle is long. [0003] In view of the above-mentioned defects, the author of the present invention has finally obtained this creation through long-term research and practice. Contents of the invention [0004] The object of the present invention is to provide a four-coordinate autom...
