An automatic clamping and positioning device for positive tee welding

Abstract

The invention relates to an automatic clamping and positioning device for tee joint welding. The automatic clamping and positioning device comprises a branch pipe conveyor and a main pipe rotating device, wherein the branch pipe conveyor comprises a belt conveyor, a distance sensor is arranged in the middle of the belt conveyor, detection via holes are uniformly arranged on the belt conveyor and right above the distance sensor, a row of first air cylinders corresponding to the detection via holes are arranged on the belt conveyor along the operation direction of the belt conveyor, support plates are fixed at the upper ends of the first air cylinders, the right sides of the support plates are provided with circular through holes, and branch pipe fixing rings coaxial with the circular through holes are arranged on the circular through hole. Branch pipes and a main pipe can be clamped and fitted together by specific equipment, the number of the used devices is decreased, and integrated degree and assembly efficiency of the branch pipes and the main pipe are improved. Since lateral supports are fixed on the belt conveyor, the lateral supports and the belt conveyor are in close fit, oscillating claws can clamp the main pipe with less error, and success rate of the oscillating claws rotating the main pipe is increased.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment of positive tees, in particular to an automatic clamping and positioning device for welding of positive tees. Background technique [0002] Tee pipes, especially positive tee pipes, are widely used in pipe networks for conveying liquids and gases, and are often used to change the flow direction of fluids. The commonly used materials are cast iron, cast steel, cast copper, cast aluminum, plastic, glass, etc., and are generally used in one piece The forming method ensures the tightness of the tee pipe. However, the production of pipes by casting or injection molding requires a large amount of equipment and complex production processes, so the production cost is high and the production efficiency is low. For most tee pipes that do not have strict sealing requirements, more welding should be used. The way of using profiles to process positive tees can reduce equipment usage, reduce pr...

Problems solved by technology

However, the production of pipes by casting or injection molding requires a large amount of equipment and complex production processes, so the production cost is high and the production efficiency is low. For most tee pipes that do not have strict sealing requirements, more welding should be used. The way of using profiles to process positive tees can reduce equipment usage, reduce processing difficulty, save production costs, improve processing efficiency, and meet modern simple and efficient production requirements.
