[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] , This kind of welding equipment for automobile parts clamps the automobile parts by means of a clamping clamp, and aligns the welding part of the automobile parts with the arc center point of the adjusting plate, then the telescopic rod contracts to allow the clamping ring to enter the cross groove, at which time the telescopic rod and the clamping clamp are fixed, and the welding angle between the two automobile parts can be adjusted by loosening the pressure ring 2 and sliding the adjusting roller 1 along the groove 3, and since the welding center point is located during installation, it is very convenient to adjust the angle, thereby improving the welding flexibility of the equipment.

[0016] , This kind of welding equipment for automobile parts, through the design of the clamping ring and the cross groove, initially, the clamping clamp and the telescopic rod can rotate relative to each other, so that when clamping automobile parts of different shapes, by adjusting the angle of the clamping clamp, the tail end of the automobile part can still be clamped after aligning the arc center point of the adjustment plate at the welding point. After clamping, the clamping ring is adjusted by adjusting the angle to re-engage the telescopic rod, and the telescopic rod is contracted to enter the cross groove, thereby completing the locking of the clamping clamp. In this way, the equipment can clamp automobile parts of various shapes, thereby increasing the types of welding of the equipment.

[0017] This kind of welding equipment for automobile parts drives the rotating drum 2 to rotate by starting the motor 1, and the rotating drum 1 rotates through the belt connection, and finally drives the rotating fan to rotate. After the welding is completed, the welding position is blown from the back side. On the one hand, it can quickly cool the welding point, and on the other hand, the welding residue will also be blown away by the rotating fan, thereby cleaning the welding slag and improving the cooling effect and cleaning effect of the device.

[0018] This kind of welding equipment for automobile parts can only flip downward with the welding point as the center through the design of the adjustment plate. In this way, the welding slag on the lower side will automatically fall off under the action of gravity during the welding process. The welding slag on the upper side of the welding point can also be well removed by the wind force of the rotating fan because the height of the walls on both sides of the welding point is relatively small, thereby improving the effect of the device in cleaning welding slag.

[0019] This kind of welding equipment for automobile parts, through the connection of shaft column two, shaft column three and connecting column, makes the welding mechanisms on the upper and lower sides rotate under the action of motor one, and in the process of the connecting plate rotating with the connecting column as the axis, the welding column plate and the side rollers are driven to perform parallel circular motion with the connecting column as the axis, so that the welding heads on the upper and lower sides reach the welding point at the same time, and the welding point is welded synchronously on the upper and lower sides, thereby improving the welding efficiency of the device.

[0020] , a welding device for automobile parts, when the welding head contacts the automobile parts, it will weld them, so by adjusting the rotation speed of the welding column plate and the rotation speed of the motor two, when the forward speed of the moving block is equal to the movement speed of the welding column plate, the telescopic column controls the welding head to just contact the welding point, so that the welding point can be distributed in a point shape, when the telescopic column controls the welding head to drop to a position beyond the welding point, when the welding head contacts the automobile parts, it will be welded, under the action of spring one, the welding head will stay in a longer position on the automobile parts, so that the welding point is strip-shaped, and by adjusting the position of the upper and lower discs, the distribution of the upper and lower welding points can also be adjusted, which greatly improves the adjustability and diversity of the welding of the device.

The snap ring 420 is adapted to the cross groove 417.

[0043] Working principle:

[0044] The first step: clamp the automobile parts with the clamping clamp 415, and align the welding part of the automobile parts with the arc center point of the adjustment plate 407, then the telescopic rod 418 is contracted to make the clamping ring 420 enter the cross groove 417, at this time, the telescopic rod 418 and the clamping clamp 415 are fixed, and the welding angle between the two automobile parts can be adjusted by loosening the pressure ring 2 414 and sliding the adjustment roller 1 410 along the groove 3 409. Since the welding center point is located during installation, it is very convenient to adjust the angle, thereby improving the welding flexibility of the equipment.

[0045] Step 2: Through the design of the retaining ring 420 and the cross groove 417, initially, the clamping clamp 415 and the telescopic rod 418 can rotate relative to each other, so that when clamping automobile parts of different shapes, by adjusting the angle of the clamping clamp 415, the tail end of the automobile part can still be clamped after aligning the arc center point of the adjustment plate 407 at the welding point. After clamping, the retaining ring 420 is adjusted in angle to re-engage the telescopic rod 418, and the telescopic rod 418 is contracted to enter the cross groove 417, thereby completing the locking of the clamping clamp 415. In this way, the device can clamp automobile parts of various shapes, thereby increasing the types of welding of the device.

[0046] Step 3: The motor 1 207 is started to drive the drum 2 209 to rotate, and the belt 205 is used to connect the drum 1 203, and finally the fan 204 is driven to rotate. After welding is completed, the welding position is blown from the back side. On the one hand, the welding point can be quickly cooled, and on the other hand, the welding residue will also be blown away by the fan 204, thereby cleaning the welding slag and improving the cooling effect and cleaning effect of the device.

[0047] Step 4: Through the design of the adjustment plate 407, the automobile parts on both sides can only be turned downward with the welding point as the center. In this way, the welding slag on the lower side will automatically fall off under the action of gravity during the welding process. The welding slag on the upper side of the welding point can also be well removed by the wind force of the rotating fan 204 due to the small height of the walls on both sides of the welding point, thereby improving the effect of the device in cleaning welding slag.

[0048] Step 5: Through the connection between shaft column 208, shaft column 312 and connecting column 318, the welding mechanisms 3 on the upper and lower sides are rotated under the action of motor 1 207. In the process of the connecting plate 317 rotating with the connecting column 318 as the axis, the welding column plate 301 and the side roller 302 are driven to perform parallel circular motion with the connecting column 318 as the axis, so that the welding heads 316 on the upper and lower sides reach the welding point at the same time, and the welding point is synchronously welded on the upper and lower sides, thereby improving the welding efficiency of the device.

[0049] Step 6: When the welding head 316 contacts the automotive parts, it will be welded. By adjusting the rotation speed of the welding column plate 301 and the rotation speed of the motor 2 403, when the forward speed of the moving block 406 is equivalent to the movement speed of the welding column plate 301, the telescopic column 315 controls the welding head 316 to just contact the welding point, so that the welding point can be distributed in a point shape. When the telescopic column 315 controls the welding head 316 to drop to a position beyond the welding point, the welding head 316 will be welded when it contacts the automotive parts. Under the action of the spring 1 314, the welding head 316 will stay in a longer position on the automotive parts, so that the welding point is strip-shaped. In addition, by adjusting the position of the upper and lower discs 306, the distribution of the upper and lower welding points can also be adjusted, which greatly improves the adjustability and diversity of the device welding.
