Accurate positioning combined clamp used for guide pipe type part welding

Abstract

The invention discloses an accurate positioning combined clamp used for guide pipe type part welding. The accurate positioning combined clamp comprises a first guide pipe and a second guide pipe, the first guide pipe comprises a first channel and a first end opening, and the second guide pipe comprises a second channel and a second end opening. The accurate positioning combined clamp used for guide pipe type part welding further comprises a connecting ring, a limiting ring and a positioning ring, an annular clamping groove is located in the position close to the end opening of the first guide pipe, the positioning ring cooperates with the annular clamping groove and comprises an annular outer side wall, one annular end and the other annular end, the position, close to one annular end, of the annular outer side wall of the positioning ring stretches into the second channel and is fixedly connected with the inner side wall of the second channel, and the other annular end of the positioning ring is connected with the annular clamping groove in a clamped manner. Technical prejudice existing in the prior art is overcome, existing deformation hidden dangers are reduced, and the clamp for welding achieves the use effect of protection when the first guide pipe and the second guide pipe are used for a long time after being welded and connected.

Description

technical field [0001] The invention relates to a precise positioning combined fixture for welding conduit parts, and belongs to the technical field of welding processing of conduit parts. Background technique [0002] The welding of conduit parts involves the positioning of two conduits, that is, the positioning of the first conduit and the second conduit. The technical bias in the prior art is that the positioning of the first conduit and the second conduit during welding is Clamping the outer wall of the first conduit and the second conduit for positioning, on the one hand causes the clamp to clamp the first conduit and the second conduit respectively, requiring the use of clamping tools, the structure is relatively complicated, and there is a problem with the first conduit and the second conduit The hidden danger of clip deformation, and the outer wall is usually welded during welding. If the inner wall of the first conduit and the second conduit are used in a complicate...

[0002] The welding of conduit parts involves the positioning of two conduits, that is, the positioning of the first conduit and the second conduit. The technical bias in the prior art is that the positioning of the first conduit and the second conduit during welding is Clamping the outer wall of the first conduit and the second conduit for positioning, on the one hand causes the clamp to clamp the first conduit and the second conduit respectively, requiring the use of clamping tools, the structure is relatively complicated, and there is a problem with the first conduit and the second conduit The hidden danger of clip deformation, and the outer wall is usually welded during welding. If the inner wall of the first conduit and the second conduit are used in a complicated environment, the welding of this outer wall will not be better for the inner wall of the first conduit and the second conduit. The use effect of protection cannot be achieved by using the clamp for welding to play a protective use effect when the first conduit and the second conduit are welded and connected for a long time
