Embodiment 1

[0030] see Figure 1-8 As shown, a welding tool for vertical pressure tank heads of the present invention includes a limit adjustment platen 1, a welding frame 2 and a support frame 3, the upper surface of the limit adjustment platen 1 and the two welding frames 2 and several support frames 3 are clamped, and the welding frame 2 and the support frame 3 are slidingly matched with the limit adjustment platen 1; the welding frame 2 and the support frame 3 are fixed with the limit adjustment platen 1 by bolts ; wherein the two welding frames 2 can be fixedly installed, but in actual work, according to the specifications and dimensions of the pressure tank, one side of the welding frame 2 needs to be fixedly installed, and the other side is adjusted with the size of the pressure tank. The distance between the two then fixed;

[0031] The surface of the welding frame 2 is sleeved with a clamping shaft 201, and the clamping shaft 201 is slidably matched with the welding frame 2, and...

Embodiment 2

[0039] It should be further explained that, in the present invention, the drive motors 206 mounted on the surface of the two soldering frames 2 work independently of each other, and only drive and control the rotational speed of the welding sleeve 202; When the stopper 2023 contacts, the welding torch 2022 is lifted to a certain height, breaks away from the welding seam, and forms a breakpoint at the welded part; In the process of lifting and resetting, all solder joints are finally connected into welding wires, and the welding work can be completed.

Abstract

The invention discloses a welding tool for the head of a vertical pressure tank and relates to the technical field of pressure tank production. The invention comprises a position-limiting adjustment platen, a welding frame and a supporting frame. A clamping shaft is arranged inside the welding frame, and a clamping cover is provided on the surface thereof. The stopper on the surface of the position rod is in contact with the support block on the surface of the clamping cover. The invention controls the distance between the welding torch and the head by setting the clamping cover and the welding sleeve, and uses the contact between the support block on the surface of the clamping cover and the stopper on the surface of the limit rod, and completes the welding work by means of continuous and intermittent electric welding. , which can avoid the distortion and irregularity of the welding seam caused by the shaking of the welding torch or equipment during a continuous welding process, and make the welding work more stable and balanced as a whole; among them, the number of even-numbered blocks and the odd-numbered number of support blocks Repeated contact and separation can displace diagonal welding after diagonal spot welding, and finally connect the welding spots into welds to complete welding.

Description

technical field [0001] The invention belongs to the technical field of pressure tank production, and in particular relates to a welding tool for a vertical pressure tank head. Background technique [0002] The pressure tank is an important equipment in the closed water circulation system, and its quality directly affects the working efficiency of the closed water cycle; the pressure tank includes the tank body and the head, and the head and the tank body are fixed by welding; and because the head It has a certain arc structure itself, and the connection structure between it and the tank body is arc-shaped. For example, in the head welding processing tool of a liquid ammonia tank disclosed in the Chinese invention patent (CN108453458A), a welding robot is used to weld the arc-shaped Although the welding robot can work stably under the control of the program, this continuous welding method often causes irregular weld distortion due to the vibration of the equipment or the work...
