This invention discloses a long-stroke, narrow-body automatic welding torch and an automatic welding equipment for expansion joint embedded parts, belonging to the field of automatic welding technology. The automatic welding torch includes a long, narrow housing, a drive mechanism, a transmission mechanism, a welding torch execution component, and a position detection component. These components are arranged side-by-side along the width of the housing, achieving a narrow body and long stroke design. Combined with an insulation structure and precise position detection, it ensures operational safety and positioning accuracy. The welding equipment includes a welding device, an automatic feeding mechanism, a discharging component, and a stud feeding mechanism. The welding device is equipped with at least two of the aforementioned automatic welding torches. The feeding, stud feeding, and discharging mechanisms respectively achieve stable transport of the embedded parts by their own weight, isolated lifting of individual studs, and automatic unloading of finished products. This invention achieves fully automated operation, enabling simultaneous stud picking and time-sharing welding with multiple torches. It solves the problems of low efficiency, poor quality, and material jamming / deviation associated with traditional equipment, improving welding efficiency and product consistency, and is suitable for large-scale mass production.

This utility model relates to the field of welding equipment technology, specifically to an ultrasonic battery frame welding device with multiple welding heads. It includes a frame, a top plate connected to the upper part of the frame, and several cylinders mounted on the top plate. A connecting frame is fixedly connected to each cylinder, and a mounting box is driven to the lower end of the piston rod of each cylinder. A mounting ring is fixedly connected to the lower part of the mounting box. This utility model uses multiple cylinders to drive multiple welding heads to work synchronously, enabling simultaneous welding of different parts of the new energy vehicle battery frame. This significantly shortens the welding cycle, improves production efficiency, and is suitable for large-scale mass production. Through the clutch control of the lifting insulating rod and the power socket, the welding head only activates the cooling element when not welding, avoiding energy loss during the welding process and effectively reducing the temperature of the welding head.

This application provides a tooling fixture for welding the duct of an axial flow fan, including a base with a fixing ring in the middle. The base and the fixing ring are connected by a slide rail, a slider is mounted on the slide rail, and an integrally formed abutment plate is provided on the top end face of the slider. A pressure block is provided on the slider for cooperating with it, and a tooling fixture for clamping the duct body is provided on the top end face of the pressure block. This utility model, by adding multiple tooling fixtures that cooperate with the abutment plate and pressure block, achieves clamping of the duct body from multiple positions, effectively preventing displacement during welding, significantly improving welding quality, and resulting in higher weld consistency.

The application belongs to the field of industrial automation, and relates to a servo spot welding control method of an industrial robot based on an integrated control system.The method comprises the following steps: moving a robot body loaded with servo spot welding tongs to a predetermined welding starting position of a workpiece through a robot controller; controlling electrodes of the welding tongs to move towards the workpiece until it is considered that the electrodes of the welding tongs successfully contact the workpiece; controlling the electrodes of the welding tongs to contact the workpiece and apply a target welding pressure, calculating a measured plate thickness and comparing the measured plate thickness with a preset expected plate thickness, and sending a welding start signal to a spot welding machine when the comparison result meets a preset threshold condition; and after receiving a welding completion signal, controlling an output torque of a servo motor to be zero, and controlling the electrodes of the welding tongs to open to an end position at a preset second speed.The application can accurately control welding pressure, welding position and timing of servo spot welding tongs, can prevent poor welding spots caused by excessive gaps between workpieces or positioning errors, and improves welding quality and efficiency.
