Intermittent rotating mechanism for workbench

Abstract

The invention provides an intermittent rotating mechanism for a workbench and belongs to the technical field of machining. The intermittent rotating mechanism for the workbench comprises an output shaft, the workbench, positioning assemblies, a pin wheel, pin rollers, a mobile cam, a guide rod, a sliding block and a drive oil cylinder, wherein the output shaft is vertically and rotationally arranged on a bearing plate; the workbench is arranged at the upper end of the output shaft in a concentric mode; the pin wheel is arranged at the lower end of the output shaft in a concentric mode; the pin rollers are arranged on the pin wheel at equal intervals in an equal circumference mode; the sliding block is arranged on the guide rod in a mode that the sliding block can slide leftwards and rightwards, and the sliding block is fixedly connected with the mobile cam; a drive cylinder body of the drive oil cylinder is fixedly installed on a left support; the right end of a drive piston rod is connected with the sliding block; positioning grooves of the positioning assemblies are formed below the workbench at equal intervals; a positioning air cylinder comprises a positioning cylinder body and a positioning piston rod; the positioning cylinder body is fixed to the bearing plate; and a positioning ring is arranged at the upper end of the positioning piston rod. By means of the intermittent rotating mechanism for the workbench, intermittent rotation of the workbench is achieved, and the workbench can be positioned accurately through the positioning assemblies.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an intermittent turning mechanism of a worktable. Background technique [0002] The shutter wheel is a strong elastic grinding disc, which is made of plastic or fiber mesh cover and emery cloth sheets. It is mainly used for grinding and polishing in industrial production, specifically for rust removal, paint removal, deburring and grinding of various types of metal and non-metal materials in shipbuilding, automobiles, aviation, machinery, instruments, bridges and construction industries and furniture. welds. In the automatic production of the louver, the chassis of the louver is placed on the station plate on the slewing mechanism, and is transported to the corresponding station with the rotation of the slewing mechanism. According to the production process of the louver, the louver With the rotation of the slewing mechanism, the chassis of the chassis passes through the gl...

Problems solved by technology

In the automatic production of the louver, the chassis of the louver is placed on the station plate on the slewing mechanism, and is transported to the corresponding station with the rotation of the slewing mechanism. According to the production process of the louver, the louver With the rotation of the slewing mechanism, the chassis of the chassis passes through the gluing station for gluing, the cutting and arranging station for blade arranging, and the shaping station for shaping the blades on the chassis, and finally outputs the finished product; the station plate on the slewing mechanism When rotating to the corresponding station, the slewing mechanism stops rotating and positions the station, so that the station equipment can be produced and processed accurately, while the slewing mechanism in the prior art controls the servo motor to stop rotating to perform station positioning. Impossible to accurately locate the station, resulting in poor consistency of the louvers and quality cannot be guaranteed
