[0014] S1. This device is connected to a conventional automated production line or structure through a rack assembly. The rack assembly is the general carrier for placing all devices and structures of the present invention. All workpiece welding debugging and operation procedures can be directly controlled by a tablet control computer. The emergency stop device realizes emergency stop when the operation is abnormal. The three-color light is displayed in different colors according to the real-time status of the device. When the device is operating, the grating can prevent objects or human bodies from accidentally touching it to avoid production accidents. The welding part fixing fixture in this device is a replaceable fixture, that is, different tooling schemes are implemented for different products. The two sides of the upper frame are hollow structures, which are convenient for access to the automated transportation and fixation of the workpiece. After the welded parts are transported to the welded parts support plate, they are fixed from top to bottom by connecting to other automated equipment;

[0015] S2. Considering that the thickness of some high-strength steel weldments is relatively thick, if the temperature around the weld does not meet the requirements during the welding process, the processing yield rate will be directly reduced. The welding part of the workpiece is preheated by the heating component. At this time, the linear module is started, and the preheating device is transported to the weld of the workpiece for heating. Among them, the linear module is mainly used in two places in this device, one is the linear movement of the preheating device, and the other is the linear movement of the welding device. The number of uses is that the preheating device uses one set of linear modules, and the welding device uses two sets of linear modules. What is specifically embodied in the drawings and abstract drawings of the specification is one set of linear modules of the welding device, which does not mean that the present invention has only one linear module, but takes the linear module pointed out as an example to explain. When the motor A is started, its output shaft drives the screw shaft A to rotate through the coupling A, and the screw shaft A drives the connecting block A to move along the axis through the screw screw block A. When the connecting block A moves, the preheating device is driven to follow the movement through the upper support plate. When the preheating device moves, its upper support plate moves along the guide shaft of the lower frame, so as to ensure Maintaining its stability, the linear module stops running after the preheating device moves to the welding part, and then starts the motor B. When its output shaft rotates, it drives shaft A to rotate through coupling B, and shaft A drives the cam to rotate. When the cam rotates, it drives the diamond connecting rod to rotate through pulleys and pivot A. When the diamond connecting rod rotates, it drives shaft B to rotate along the lower support shaft plate A, lower support shaft plate B, and lower support shaft plate C. When the diamond connecting rod rotates, it drives connecting rod A to move downward through pivot B. Connecting rod A drives connecting block B to move downward through pivot C. Connecting block B drives heating module A to move downward through the connecting rod. At the same time, when the diamond connecting rod rotates, it drives connecting rod B to push upward. Connecting rod B drives push rod A to push upward along guide shaft seat C and guide shaft seat D through pivot D. Push rod A drives heating module B to push upward through the heating module fixing plate. At this time, heating module A and heating module B clamp the weld of the welding part up and down, and then heat it. When the temperature of the weld of the welding part detected by heating module A and heating module B reaches the welding requirement, the preheating device is reset, and then the linear module at the preheating device is reset;

[0016] S3, then start the linear module for the welding device, move the welding device to the working range of the welding part, start the motor C, when its output shaft rotates, it drives the screw shaft B to rotate through the coupling C, when the screw shaft B rotates, it drives the connecting block C to move linearly through the screw screw block B, when the connecting block C moves, it drives the drag chain A to move through the drag chain bracket A, when the connecting block D moves, it drives the welding assembly to move horizontally through the connecting block D, when the motor D is started, its output shaft drives the screw shaft C to rotate through the coupling D, when the screw shaft C rotates, it drives the welding assembly fixed bracket to move up and down through the screw screw block C, when the welding assembly fixed bracket moves, it drives the welding assembly to move up and down, and drives the welding assembly through the above-mentioned structure and function. The welding assembly is moved to the operation origin of the welded part, and the welding operation is performed through the preset program of the tablet control computer. When the motor E is started, its output shaft drives the screw shaft D to rotate through the coupling E. When the screw shaft D rotates, the mounting plate is driven to move linearly along the arrangement direction of the screw shaft D through the screw screw block D. When the mounting plate moves, the drag chain B is driven to follow the movement through the drag chain connecting plate. When the mounting plate moves, the visual sensor component is driven to follow the movement through the bracket A and bracket B. The working stroke of the screw shaft D meets the observation requirements of the visual sensor component in the frame assembly. During the operation, the visual sensor device is used to observe, record and analyze the welded parts during the welding operation, which plays a key role in preventing and stopping the generation of defective parts.

It can realize fully automated welding of welding workpieces and has the conditions for intelligent processing of welded parts; 2. It can preheat the weld seam of welded parts; 3. The fixture can be replaced quickly, the structure is simple, the types of processed parts are many, and the device has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

Considering that some high-strength steel welded parts are relatively thick, if the temperature around the weld does not meet the requirements during the welding process, the processing yield will be directly reduced. The welding part of the workpiece is preheated by the heating component. At this time, the linear module (2) is started, and the preheating device (3) is transported to the weld of the workpiece for heating. Among them, the linear module (2) is mainly used in two places in this device, one is the linear movement of the preheating device (3), and the other is the linear movement of the welding device (4).
