Description

Technical Field

[0001] The invention relates to the technical field of electric welding machine brackets, in particular to an adjustable bracket for an electric welding machine. Background Art

[0002] In the actual processing of special-shaped parts, welding work is often involved. Welding is widely used as a strong connection process. For example, in the manufacturing of oil cylinders, welding work is required between the cylinder body and the oil port of the oil cylinder. Because the cylindrical structure of the oil cylinder is arc-shaped on the outside, the oil port welding needs to ensure accuracy to avoid leakage. When welding with an electric welder, a bracket is required to clamp the oil cylinder and the oil port to ensure stable welding. At the same time, the welding gun head of the electric welder also needs to ensure welding stability. The current adjustable bracket of the electric welder is not convenient for adjusting the weld seam for the oil port. Most of them directly stick the oil port to the cylinder body, and the welding firmness is not good. At the same time, it is not convenient to enhance the welding penetration through negative pressure, and the welding depth is not enough. At the same time, the welding of the oil port is not convenient for welding path detection, and subsequent detection station detection is required. If problems are found, it is not convenient to deal with them in time, which affects the processing efficiency.

The welding rotating member 2 can be used to realize comprehensive welding work around the oil port, and at the same time At the same time, the lifting and positioning member 3 of the present structure utilizes its own liftable structure, cooperates with the positioning tube 3011 to pass through the oil port and insert into the oil port hole of the oil cylinder to realize the positioning work, thereby ensuring the installation accuracy of the oil port.

The structure is more reasonable, and the accuracy and quality of the oil port welding can be ensured. The protective ring 305 is used to prevent welding slag from splashing in the weld.

[0041] like Figure 6 to Figure 7As shown, the weld locating member 4 includes a pressing locating ring 401 fixedly sleeved on the locating cylinder 3011, and a ring magnet 402 is fixedly embedded at the bottom of the pressing locating ring 401; a bolt connecting plate 403 is fixedly installed on the side of the pressing locating ring 401, and a threaded hole is provided on the bolt connecting plate 403; a positioning bolt 404 is threadedly connected to the threaded hole on the bolt connecting plate 403; a hand wheel is provided at the end of the positioning bolt 404; the pressing locating ring 401 is used to press the oil port to fit the oil cylinder.

On the other hand, the The weld locating piece 4 can locate the oil port, and can cooperate with the lifting locating piece 3 to quickly adjust the size of the welding seam between the oil port and the oil cylinder. The adjustment is flexible and accurate, which ensures the firmness of subsequent welding and avoids the oil port being directly attached to the oil cylinder for welding, resulting in insufficient firmness of the external connection.

After welding is completed, the welding uniformity of the welding path can be checked to avoid excessive welding or welding that is too thin and thus reduce the firmness. The structure is more reasonable, the detection method is mature and efficient, and problems can be dealt with in a timely manner when they are found. There is no need for subsequent tedious quality inspection and other work. The welding support arm 201 can be rotated around the outside of the oil port to perform welding work by hand-holding.

[0043] The working principle provided by the present invention is that, firstly, the structure is installed on the ground by passing bolts through the four through holes provided on the support plate 101, the oil cylinder barrel is placed between the two clamping blocks 104, and the two clamping blocks 104 are driven to clamp the oil cylinder barrel by rotating the clamping screw 103, and then the oil port is placed on the oil cylinder barrel. Under the pull of the positioning tension spring 306, the positioning cylinder 3011 can be inserted into the oil port and the oil port hole on the oil cylinder for positioning. When the subsequent welding work is carried out, the negative pressure suction fan 303 can be started to use the negative pressure suction hole 302 for suction to improve the welding efficiency. Penetration effect, after the welding of the welding machine is completed, the lifting slide column 301 can be pulled to remove the positioning cylinder 3011 from the oil port, and then the oil port of the oil cylinder can be disassembled. Under the pull of the positioning tension spring 306, the positioning ring 401 is pressed down, and the oil port is adsorbed by the annular magnet 402. At this time, the oil port is close to the oil cylinder under pressure, and the positioning oil port can be squeezed by tightening the positioning bolt 404. By rotating the weld adjustment bolt 304, the weld adjustment bolt 304 can drive the lifting slide column 301 to lift and adjust, and the lifting slide column 301 can drive the oil port lifting adjustment and the weld between the oil cylinder The size of the seam is simple and flexible to operate. At the same time, after the oil port weld is positioned, the welding gun head 603 is used for spot welding. Finally, the weld adjustment bolt 304 can be rotated and removed to release the oil port positioning. The annular magnet 402 is used to absorb the upper edge of the oil port for positioning. The magnetic connection does not affect the subsequent welding support arm 201 to perform welding around the outer periphery of the oil port. At the same time, the welding accuracy can be ensured. The welding adapter rod 601 can be pulled by rotating the adapter tension spring 502 to pull elastically, and the welding gun head 603 on the welding adapter rod 601 can be pulled by cooperating with the seam tension spring 6011. The weld can be aligned for adaptation. As the welding support arm 201 is rotated, the welding positioning column 602 can be guided in the weld so that the welding gun head 603 can be aligned with the weld. After welding is completed, the welding support arm 201 can be pushed to rotate one circle. At this time, the detection column 702 can be attached to the weld. If the weld is not connected at the beginning and the end or is uneven, its surface will be uneven. At this time, the detection column 702 will be attached to the weld to detect the rapid changes in the unevenness. After detection by the linear displacement sensor 703, the controller 203 can control the alarm light 202 to light up and alarm.
