[0002] When welding flange rings on round or oval workpieces, the existing process is to fix the workpiece with a three-jaw chuck, and then drive the three-jaw chuck to rotate to drive the workpiece to rotate, and then complete the welding process. However, due to reasons such as machining accuracy or the requirements of its own appearance, the radius of the workpiece fluctuates. Since the position of the welding gun remains fixed, the weld cannot maintain consistency with the connection with the workpiece, thus affecting the welding quality. Summary of the invention

[0003] The purpose of the present invention is to provide a flanging ring automatic welding device to improve the welding quality in view of the above problems.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is an automatic welding equipment for flanging rings, which includes a machine platform, a processing table is provided on the upper end of the machine platform, a clamping mechanism is provided on the processing table, a welding gun is provided above the clamping mechanism, and the welding gun is installed on the displacement mechanism; the clamping mechanism includes a bracket, a support is provided on the bracket, a fixed seat and a sliding seat are provided on the support, the sliding seat is provided on both sides of the fixed seat, the sliding seat and the fixed seat are distributed in a plane triangle, the sliding seat slides along the line connecting it and the fixed seat, and the fixed seat and the sliding seat are both provided with transmission wheels, and at least one transmission wheel is connected to the driving motor. The transmission wheel supports the side wall of the workpiece, and during processing, the sliding seat moves with the workpiece, and then the welding gun moves to the welding position for welding to ensure that the weld is consistent with the connection between the weld and the workpiece, thereby improving the welding quality.

[0005] Furthermore, in order to improve safety, a circle of guardrails is provided at the upper end of the machine platform outside the processing table, one side of the guardrail is open as an operating area, and a safety door for controlling the opening and closing of the operating area is provided on the guardrail.

[0006] Furthermore, the displacement mechanism includes a fixed vertical guide rail, a transverse beam is arranged on the vertical guide rail, a transverse guide rail is arranged on the transverse beam, a transverse seat is arranged on the transverse guide rail, a welding gun seat is arranged on the transverse seat, and the welding gun is installed on the welding gun seat. In this way, the welding gun can be adjusted along the radial direction of the workpiece to adapt to workpieces of different specifications; the welding gun moves up and down, which can facilitate the taking and placing of the workpiece.

[0007] Furthermore, the welding gun seat is provided with a wire feeding guide tube with an outlet facing the working area of ​​the welding gun.

[0008] Furthermore, the welding gun seat can be adjusted in height through an adjustment mechanism on the transverse seat to adapt to workpieces of different specifications and improve welding quality.

[0009] Furthermore, in order to facilitate the staff to adjust the height of the welding gun, the adjustment mechanism includes an adjustment gear, which is installed on the transverse displacement seat through a rotating shaft concentric therewith, and the adjustment gear is meshed with the vertical rack, and the lower end of the vertical rack is fixedly arranged on the welding gun seat, and the adjustment mechanism also includes a locking seat for locking the vertical rack.

[0010] Furthermore, a swing shaft is rotatably arranged on the bracket, and the support is arranged on the swing shaft. The axis of the swing shaft is in the same direction as the line connecting the two sliding seats, so that the angle of the support can be adjusted according to workpieces of different specifications, and then the angle and position of the workpiece and the welding gun can be adjusted to meet different processing requirements.

[0011] Furthermore, in order to drive the support to swing and realize self-locking at the same time, a circle of worm gear concentric with the swing shaft is provided, and a worm is rotatably provided on the bracket, and the worm and the worm wheel are matched.

[0012] Furthermore, in order to prevent the workpiece from falling and ensure that the workpiece rotates with the transmission wheel, a circle of concentric grooves is provided on the side wall of the transmission wheel.

[0013] The beneficial effects of the present invention are as follows: before welding, the workpiece is placed in the space enclosed by the fixed seat and the sliding seat, and then the sliding seat moves toward the workpiece, so that the transmission wheels on the fixed seat and the sliding seat simultaneously support the side wall of the workpiece. Then the transmission wheel drives the workpiece to rotate, and at the same time the welding gun descends to the welding position for welding; during welding, the sliding seat can move with the side wall of the workpiece, thereby ensuring that the weld and the connection between the workpiece are consistent, and improving the welding quality.

[0030] Specific working process: the operation area is opened, the staff places the workpiece 24 between the fixed seat 6 and the sliding seat 7, then one staff temporarily fixes the workpiece 24, and inserts the edge of the workpiece 24 into the slot of the transmission wheel 8 on the fixed seat 6, and then another staff operates the cylinder to move so that the sliding seat 7 moves toward the workpiece 24, so that the edge of the workpiece 24 is inserted into the slot of the transmission wheel 8 on the sliding seat 7.

[0031] After the workpiece 24 is fixed, the worm 22 is rotated to adjust the angle of the support 5 to ensure that the welding gun is aligned with the welding point of the workpiece 24, and then the drive motor 9 is turned on to drive the transmission wheel 8 to rotate, and the transmission wheel 8 drives the workpiece 24 to rotate, and at the same time the welding gun is lowered to perform welding. During the rotation of the workpiece 24, when the long axis side of the workpiece 24 contacts the transmission wheel 8, the sliding seat 7 is pushed to move toward the far end of the fixed seat 6, and when the short axis side of the workpiece 24 contacts the transmission wheel 8, under the action of the cylinder, the sliding seat 7 moves toward the near end of the fixed seat 6, thereby ensuring that the weld meets the requirements.

[0032] Embodiment 2, as Fig.10 As shown, the other structures and working processes of this embodiment are the same as those of the embodiment 1, but in this embodiment, the two sliding seats 7 move synchronously, and for this purpose, the support 5 is provided with a sliding frame 26 that moves along the adaptable guide rail 27, the adaptable guide rail 27 extends to one side of the fixed seat 6, and the adaptable guide rail 27 is arranged on the back of the support 5.
