Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to an adaptive adjustable welding device and a use method thereof. Background Art

[0002] ‌Welding equipment refers to the equipment required to implement the welding process, mainly including welding machines, welding process equipment and welding auxiliary tools. The main types of welding equipment are electric welders, flame welding equipment and other welding equipment. Among them, plasma arc welding refers to a fusion welding method that uses the high energy density beam of plasma arc as the welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed, small stress and deformation, stable arc and suitable for welding thin plates and box materials. It is particularly suitable for the welding of various refractory, easily oxidized and heat-sensitive metal materials.

[0003] However, the existing welding equipment has many limitations. In terms of workpiece fixation, common welding equipment mostly uses simple clamps and bolts to fix the workpiece. This fixing method is cumbersome to operate, and it is difficult to achieve precise fixation when facing irregularly shaped workpieces. During the welding process, the workpiece is very prone to displacement, which seriously affects the welding quality. When welding automotive parts with complex structures, the welding defect rate caused by loose workpiece fixation is as high as 15%-20%, which not only increases production costs, but also reduces the product qualification rate.

[0004] In the process of turning over the workpiece, most of them rely on manual operation. According to industry statistics, when traditional welding equipment manually turns over the workpiece, the average auxiliary time for each welding accounts for 30%-40% of the total welding time. This not only consumes a lot of manpower, but also greatly reduces the welding efficiency, making it difficult to meet the needs of large-scale production. At the same time, most of the existing welding equipment operates in an exposed environment. A large amount of debris and smoke will be generated during the welding process, which contains a variety of harmful components, such as inhalable particulate matter, manganese and its compounds. Although some equipment is equipped with a simple local exhaust device, the exhaust range is limited and it is impossible to effectively collect a large amount of harmful gases generated during welding. Relevant studies have shown that the probability of workers who have been in a welding smoke environment for a long time is 4-6 times higher than that of normal people to suffer from respiratory diseases, posing a serious threat to the health of workers.

[0005] With the rapid development of the manufacturing industry, the requirements for welding accuracy and efficiency are increasing day by day, and automated and intelligent welding technology has become the mainstream trend of the industry. However, the existing welding equipment has a large gap with this trend in terms of automation and environmental performance, and it is difficult to meet the stringent requirements of modern industrial production. Summary of the invention

[0006] The object of the present invention is to provide an adaptively adjustable welding device and a method for using the same, so as to solve the problem that the existing welding equipment mentioned in the above background technology needs to be manually turned over during the welding process, which greatly reduces the welding efficiency, and the existing welding equipment basically welds in an exposed environment. When the workpiece is welded, debris and smoke will be generated, which will have a certain impact on the health of the workers and cause certain harm to the workers, thereby reducing the welding speed of the workpiece and the safety factor of the welding process.

At the same time, it can rotate flexibly in the through hole of the vertical plate, and will not affect the overall compactness of the equipment and the convenience of operation due to excessive or small size.

[0011] The stroke range of the electric push rod is 200mm-500mm, which can meet the welding requirements of workpieces of different heights; its maximum thrust is 3000N, which is enough to stably push the support plate and workpiece up or down, ensuring reliability and safety in the process of adjusting the workpiece height.

[0031] A method for using an adaptable adjustable welding device comprises the following steps: S1. When it is necessary to fix the workpiece, the distance between the two clamping plates is adjusted according to the length of the workpiece, and the rotating plate is rotated. The rotating plate drives the threaded rod 1 to rotate, and the threaded rod 1 rotates on the rotating column to drive the clamping plate to move. The clamping plate is limited by the telescopic rod, and the clamping plate moves stably in a horizontal straight line. When the distance between the two clamping plates moves to an appropriate distance, the rotating plate is stopped, and then the two ends of the workpiece are respectively installed in the clamping plates, and then the top plate is rotated. The rotation of the top plate drives the threaded rod 2 to rotate. When the threaded rod 2 rotates, the clamping plate is driven to move downward, and the clamping plate gradually approaches the workpiece to clamp and fix the workpiece. When the clamping plate moves, it drives the limit plate to move, and one end of the limit plate slides in the limit groove. The clamping plate is limited and supported by the limit plate, and then the workpiece is fixed.

[0032] S2. When the workpiece needs to be rotated, move the two pull plates forward. When the pull plates move, they drive the fixed rod to move. At this time, one end of the fixed rod moves out of the fixed groove. Then rotate the rotating plate. The rotating plate drives the threaded rod to rotate. The threaded rod drives the rotating column to rotate. The rotation of the rotating column drives the clamping plate to rotate. The clamping plate fixes the workpiece and drives the workpiece to rotate. Then, the workpiece can be rotated and adjusted according to the welding requirements. When the workpiece is rotated to an appropriate angle, move the pull plate again. The pull plate moves backward to drive the fixed rod to move. Move one end of the fixed rod to the corresponding fixed groove, thereby fixing the position of the rotating column and fixing the rotation angle of the workpiece.

[0033] S3. When the workpiece needs to be moved upward, the electric push rod is started, and the output shaft of the electric push rod drives the support plate to move. When the support plate moves, it drives one end of the clamping plate to slide in the clamping groove. The support plate is auxiliary supported by the clamping plate. The support plate moves upward and drives the vertical plate to move. The vertical plate drives the rotating column to move upward, and then drives the workpiece to move upward. When the workpiece is moved upward to a position that conflicts with the welding equipment body, the electric push rod is closed.

[0034] S4. When the workpiece needs to be welded, start the motor and the welding equipment body. The motor drives the reciprocating screw to rotate. The reciprocating screw drives the slide to move when it rotates. The slide moves and drives the bracket to move. The bracket drives the welding equipment body to move. Then, the welding equipment body can move slowly while welding the workpiece evenly. When the slide moves, it drives the slide plate to slide on the slide rod. The slide plate is limited and supported by the movement of the slide plate. Then, the workpiece can be fully welded.

[0035] S5. When smoke appears during welding of workpieces, start the fan. The smoke generated during welding of the welding equipment body is absorbed by the smoke pipe, and then enters the annular pipe through the smoke pipe. The smoke generated can be accurately absorbed through the annular arrangement of several smoke pipes, and then enters the connecting pipe through the annular pipe, and then enters the exhaust pipe, and is discharged to the outside after being filtered by the activated carbon filter plate.

[0036] S6. When the activated carbon filter plate needs to be disassembled and replaced, loosen the bolts, move the tail end of the bolts away from the exhaust pipe, and then move the installation cylinder horizontally, one end of the installation cylinder gradually moves away from the exhaust pipe, and then the installation cylinder can be removed to replace or clean the activated carbon filter plate on the installation cylinder, which is convenient to operate and simple in structure.

[0037] S7. When the collection frame needs to be removed, welding debris will be generated during the welding process of the welding equipment body. The debris will fall into the collection frame due to its own gravity. When the debris in the collection frame accumulates to a certain extent, grab the handle and move the collection frame upward. When the collection frame moves upward, it drives the pin to move upward. At this time, the bottom end of the pin gradually moves out of the slot, and then the collection frame can be removed to clean the debris in the collection frame.

With the function of a plurality of fixing grooves, one end of the fixing rod can be conveniently extended into the fixing groove at any time to fix the rotation angle of the rotating column. Combined with the function of the pull plate, it is convenient for the staff to move the fixing rod by moving the pull plate, and the operation is convenient. The adaptive adjustable welding equipment and the use method thereof are provided with a mounting tube, bolts and an activated carbon filter plate, and utilize the function of the activated carbon filter plate at one end of the exhaust pipe to filter and clean the odor in the absorbed flue gas, thereby preventing the flue gas from spreading into the air and causing air pollution. Combined with the function of the mounting tube and the bolts, the activated carbon filter plate is threadedly fixed on the exhaust pipe, and it is also convenient to loosen the bolts at any time in the later stage to disassemble and replace the activated carbon filter plate; The adaptive adjustable welding equipment and the use method thereof are provided with a second fixing plate, a reciprocating screw and a motor, and the reciprocating screw is rotated and fixed at the rear side by utilizing the function of the second fixing plate, and combined with the function of the threaded installation of the slide seat, the reciprocating screw is rotated when the motor is started, and the bracket drives the welding equipment body to move back and forth left and right under the function of the slide seat, so as to reciprocate and weld the workpiece, thereby ensuring the solidity of the workpiece welding, saving time and labor, and being convenient to operate; According to actual tests, compared with traditional welding equipment, the welding efficiency of the welding equipment of the present invention is improved by 30% under the same workpiece and welding process. When welding Q235 steel plates of the same specifications with a thickness of 5mm and a length of 1000mm, the traditional manual arc welding equipment takes 30 minutes to complete the welding, while the present equipment only takes 21 minutes, which greatly shortens the welding time and improves production efficiency. As for the fume absorption effect, the fan has an air volume of 500m³ / h. Together with the annular tube and the smoke pipe, it can effectively absorb more than 90% of the total fume generated during welding. Through the detection of professional testing equipment, when using this equipment for welding operations, the concentration of harmful gases in the working environment is lower than the daily average concentration limit of 0.15mg / m³ for inhalable particulate matter (PM10) and manganese and its compounds (MnO 2 The maximum allowable concentration is 0.1mg / m³, which effectively protects the health of workers.
