Description

technical field [0001] The invention relates to a turntable flame welding machine. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Different metals and workpieces with different structures require corresponding welding processes and equipment to carry out welding. As a traditional craft and technology in the manufacturing industry, welding technology has developed very rapidly in industrial applications in recent years. Welding can be divided into manual welding, semi-automatic welding, and automatic welding according to the degree of automation; among them, manual welding is manual welding with a welding torch; semi-automatic welding usually refers to the welding torch is fixed, the workpiece is rotated, and the workpiece needs to be clamped manually; automatic welding is mostly manipu...

Problems solved by technology

The set conveying track is used to transport the welding workpiece, and the conveying station on the conveying track fixes the welding workpiece, prevents the welding workpiece from deviating from the direction during conveying, and ensures the accuracy and stability of the welding workpiece conveying; the first driver drives the rotary table to rotate, Make the welding workpiece on the conveying station smoothly enter the processing station, and then fix it with the processing fixture on the processing station. After fixing, use the first driver to drive the processing station to rotate to the position of the welding torch. The correlation between the sensor and the induction switch is used for positioning to ensure that the processing station can be accurately stopped at the welding torch, the welding position of the welding workpiece is accurate, the error is reduced, the welding quality is improved, and multi-station welding is realized through multiple processing stations. Operation, can weld multiple processing materials at the same time or step by step to improve the working efficiency of the welding machine; the rotating device on the processing station drives the rotation of the welding workpiece to achieve continuous, high-quality, multi-directional welding of the welding workpiece, welding The surface is wide, and when the welding is finished or when welding at a fixed point, the locking device can lock the rotating device, so that the welding workpiece is not easy to move during fixed welding, ensuring the stability and accuracy of welding and improving safety The fixed fixture set is used to fasten the welding workpiece, and can also be changed according to the actual size of the welding workpiece, thereby expanding the scope of use of the fixture; the angle adjustment mechanism allows the welding torch and wire feeding gun to move up and down, left and right, and the adjustment range It solves the shortcomings of welding torch and wire feeding gun with fixed, single and non-adjustable strokes. It is easy to adjust and expands the welding range; the set wire feeding device effectively ensures the cleanliness of the welding wire, and straightens the welding wire to ensure the quality of the welding wire , improve wire feeding stability and welding quality, make wire feeding accurate, prevent welding wire from shifting during welding, save wire feeding time, and avoid waste; the second sensor is used to sense whether the welding station is installed on the conveying station. Workpieces, to prevent missing welding workpieces on the conveying station, resulting in a waste of time, resources and manpower, the transmitter in the second sensor sends out a signal, and the receiver receives the signal sent by the transmitter, when the conveying station is transported to the launcher by the conveying track When between the transmitter and the receiver, if there is a welding workpiece on the conveying station, the signal sent by the transmitter will be blocked by the welding workpiece, and the receiver will not receive the signal, so it will send the information to the first driver, and the first driver will drive the rotary table to rotate , rotate the processing station to the output end of the conveying track, so that the welding workpiece on the conveying station can accurately enter the processing station, and fix the welding workpiece through the processing fixture to avoid the deviation of the welding workpiece; if the conveying station does not If there is a welding workpiece, the signal sent by the transmitter can be successfully received by the receiver, and the receiver will send the information to the driver, so that the driver stops working, no need to pick up the workpiece, save working energy, avoid welding errors, and lack of welding during welding Artifact happens
