Clamp for heating and ventilation pipe welding

Abstract

The invention discloses a clamp for heating and ventilation pipe welding, and relates to the technical field of heating and ventilation production. The clamp solves the problems that operation is troublesome due to the fact that an existing pipeline welding clamp can only be used in welding of straight pipes, pipelines at other angles are difficult to clamp and weld, and meanwhile manual operationis needed during butt joint, and the welding quality is poor due to the fact that the butt joint requirement is difficult to meet due to low pipeline butt joint precision. The clamp comprises a mounting base, wherein the right side of the upper portion of the mounting base is rotationally connected with a set of swinging seats, and the upper portion of the left side of the mounting base is slidably connected with a set of seam closing sliding piece; and the rear portions of the swinging seats are hinged with a set of swinging connecting rods. According to the clamp for heating and ventilationpipe welding, automatic butt joint action on the pipelines can be achieved, meanwhile, splicing and welding between the pipelines at different mounting angles can be achieved, and the pipelines can be rotated so that the splicing angle of the pipelines can be adjusted, and the splicing precision is higher; and meanwhile, a straight pipe can be welded and rotated at the same time, so that the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of HVAC production, in particular to a fixture for welding HVAC pipes. Background technique [0002] The main functions of HVAC include: heating, ventilation and air conditioning. The comprehensive abbreviation of these three functions is HVAC. In the process of HVAC production and construction, pipes need to be welded as needed. During the welding process of HVAC pipelines, it is generally necessary to use pipeline clamps to fix the pipelines and then weld them. [0003] For example, application number: CN201810551176.4 The present invention provides a welding fixture for heating and ventilation pipelines on the construction site. The welding fixtures are two sets, which are placed on both sides of the weld to be welded and used in conjunction with each other. The welding fixtures include: clamps, clamps Head, bracket, adjustment sleeve and welding torch fixing piece, the welding torch fixing piece is arra...
