Rotation mechanism

Abstract

The invention discloses a rotation mechanism. The rotation mechanism comprises a bearing base, a rotary disc rotationally arranged on the bearing base, a drive device used for driving the rotary discto rotate around the center axis of the rotary disc, a plurality of clamping devices circumferentially arranged around the center axis of the rotary disc and jointly used for clamping workpieces, anda plurality of adjusting devices corresponding to the multiple clamping devices in a one-to-one manner. The clamping devices are arranged on the rotary disc through the corresponding adjusting devices, and the adjusting devices are used for guiding the corresponding clamping devices to move in the radial direction of the rotary disc. Each clamping device comprises a supporting base and further comprises a first clamping arm, a second clamping arm, a swinging rod, a connecting rod and an inserting piece, all of which are fixed to the supporting base. According to the rotation mechanism, the direction of the workpieces can be adjusted, meanwhile, the structure of the clamping devices is simple, air cylinders do not need to be adopted, and cost can be better reduced.

Description

technical field [0001] The invention relates to a rotating mechanism. Background technique [0002] During the workpiece welding process, the workpiece is jointly clamped by several clamping devices, and the several clamping devices are fixed on the bearing seat. However, when the workpiece is welded, different positions of the workpiece need to be welded, but at present, the orientation of the workpiece cannot be adjusted, which brings a lot of inconvenience to the welding operation; moreover, the existing clamping device includes a first clamping arm, a second The clamping arm, the first clamping arm and the second clamping arm are all driven by an air cylinder, so that the first clamping arm and the second clamping arm approach or move away from each other, which is convenient for clamping or loosening the workpiece. However, since the existing clamping device includes two cylinders, it needs to be equipped with an air distribution device, so that the cost of the clampin...

Problems solved by technology

However, when the workpiece is welded, different positions of the workpiece need to be welded, but at present, the orientation of the workpiece cannot be adjusted, which brings a lot of inconvenience to the welding operation; moreover, the existing clamping device includes a first clamping arm, a second The clamping arm, the first clamping arm and the second clamping arm are both driven by the air cylinder, so that the first clamping arm and the second clamping arm are close to or far away from each other, which is convenient for clamping the workpiece or loosening the workpiece

However, because the existing clamping device includes two cylinders, it needs to be equipped with an air distribution device, resulting in high cost of the clamping device, which is far from meeting industrial needs
