Rolling ring type positioner

Abstract

The invention provides a rolling ring type positioner, and relates to the technical field of welding equipment. The rolling ring type positioner comprises a basic rack, a turning over rack is slidably connected into an arc-shaped groove in the top end of the basic rack, a turning over driving mechanism used for driving the turning over rack to slide along the arc-shaped groove is arranged on one side of the basic rack, the turning over rack comprises a bottom plate and a side plate which are perpendicular to each other, an electric chuck used for clamping a tool core shaft of a workpiece is connected to the bottom plate of the turnover rack in a sliding mode, and a rotation driving mechanism used for enabling the electric chuck to rotate is arranged at the bottom end of the electric chuck. According to the rolling ring type positioner, the workpiece is turned in place over through clamping and turning over, the workpiece is rotated by applying reasonable rotating torque, the welding technology or other preparation technologies are finally achieved, single-side large-torque output is adopted during the turning over, it is guaranteed that the output torque is enough, the turning over is smooth, slipping is avoided in the rotating process, and the welding quality and the operation efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a rolling ring positioner. Background technique [0002] In the prior art, the welding of the pipe joint or the flange of the end is usually hoisted and placed on the roller frame, and the linear speed required for welding is provided by the rotation of the roller frame. The workpiece itself has a certain weight, and if it is placed directly on the roller frame horizontally, it is inevitable that the roundness deviation of the workpiece is too large. cause welding defects. Man-hours are spent on human operations. Especially for cylinder welding with relatively high requirements, the degree of manual participation in the production process is even greater. Late fixes caused by defects will also increase. Contents of the invention [0003] The purpose of the present invention is to provide a rolling ring positioner, aiming to solve the inevitable problems in the pri...
