Abstract

The invention discloses a self-adaptive clamping device for steel pipe welding, and relates to the technical field of welding equipment. The self-adaptive clamping device for steel pipe welding comprises a base, accommodating ring frames, a clamping device body and a control device; the base is provided with the two accommodating ring frames; inner grooves are formed in the inner walls of the accommodating ring frames; the clamping device body is mounted in the inner grooves; the tops of the accommodating ring frames are in an arc shape; and outer semicircular grooves are formed in the tops of the accommodating ring frames. According to the self-adaptive clamping device for steel pipe welding, two steel pipes needing to be welded are inserted into the accommodating ring frames, an anti-clamping device is controlled by a control device to clamp the steel pipes in the accommodating ring frames so as to finish maximum-area fitting to the arc-surface steel pipes during clamping; and in addition, the two steel pipes can be rotated in the original positions by shifting the control device to move along the outer semicircular grooves, so that the problem that the working surfaces which are not welded are gradually welded under the condition that a clamp is not loosened is solved to reduce the tedious steps of people in the welding process.

Description

technical field

[0001] The invention relates to the technical field of welding equipment, in particular to an adaptive clamping device for steel pipe welding. Background technique

[0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics.

[0003] As a device for cooperation in the welding process, the welding auxiliary device is currently widely used in various fields. However, due to the arc shape of the pipe, there are problems such as incompatibility with pipes of various sizes and the inability to adjust the welding gap. It is because the clamp used to clamp the pipe is larger than the diameter of the pipe before clamping, and the gap between the surface of the pipe cutter and the surface of the pipe cutter after the complete fit is relatively large, so that the fixed position of the pipe when it receives part of the external force Devia...
