Safe position-limiting mechanism for automatic rotary table conveying device

Abstract

The invention relates to a safe position-limiting mechanism for an automatic rotary table conveying device. The safe position-limiting mechanism for the automatic rotary table conveying device comprises a stopper arranged on a rotary table roller way, and a pressing plate arranged on a conveying roller way, wherein the stopper comprises two sleeves arranged on a bottom plate of the rotary table roller way; support rods are inserted into the two sleeves; one ends of the two support rods are connected with the bottom plate of the rotary table roller way through springs; the other ends of the twosupport rods are connected with the bottom part of one long strip-shaped stopper block; the top part of the stopper block is located above the rotary table roller way so as to stop a workpiece; the bottom part of the stopper block is connected with one end of a connecting rod; a rolling wheel seat and a rolling wheel are arranged at the other end, penetrating through the bottom plate of the rotary table roller way, of the connecting rod; two sections of inclined surfaces with opposite inclined directions are arranged at the bottom end of the pressing plate; the pressing plate is located on arotation path of the rolling wheel rotating along with the rotary table roller way, so that the rolling wheel contacts one section of the two sections of inclined surfaces and rolls along the inclinedsurface so as to drive the stopper block to move downwards, and the top part of the stopper block is located under the rotary table roller way; and through the elastic acting forces of the springs, the stopper block is reset after the rolling wheel and the pressing plate are separated.

Description

technical field [0001] The invention relates to the field of automatic turntable conveying equipment, in particular to a safety limit mechanism for an automatic turntable conveying device. Background technique [0002] With the improvement of the level of automated production in modern industry, in order to improve production efficiency and reduce labor intensity, automated conveyor lines have been widely used. The roller conveyor system is connected to realize the automatic production and transportation of workpieces; [0003] In the automatic conveying line, when the workpiece needs to change the conveying direction, it is necessary to install a turntable conveying device between the two sections of rollers in the conveying line. The workpiece is first sent to the turntable roller installed on the turntable conveying device, and then on the turntable roller Stay and turn with the roller table of the turntable, and then send it from the roller table of the turntable to the...
