Abstract
The utility model proposes small-bore welding clamp.Left pincers with right pincers the structural member being Steel Sheet, left pincers handle and right pincers are connected middle part and shaft clearance, left pincers are provided with circlip with right pincers the axle two ends in outside, axle is wound with torsionspring, torsionspring both sides support arm be against respectively left pincers with right pincers on some positions of inner side, left pincers handle and right pincers form a semi-enclosed circular contour jointly upper inner, left pincers have operation window on the steel plate outside the semiclosed circular contour with right pincers handle, the left pincers handle on operation window top and right pincers are top attachment weld clearance gauge, weld seam clearance gauge extend into left pincers inboard with the semiclosed circular contour of right pincers handle.Two pipes can be aligned by this device, and ensure weld size, can adjust the concordant degree of pipe, clamping is reliable, has easy to operate, and speed of application is fast, and not by space constraint, welding quality high, favourablely promotes the use of.
Description
Technical field:
The utility model relates to pipeline construction tooling fixture field, is specifically related to small-bore welding clamp.
Background technology:
At present, in pipeline construction, when position welding such as high-density tube row, pipeline, trenches, need two pipes to align during weld seam counterpart and retain fixing gap to ensure welding quality, the place of narrow space or light bad, the occasion such as tube welding amount is large, with the naked eye hand touches to grasp the alignment of pipe to tube work, the gap of groove is difficult to guarantee, cause the pipe mismatch that two relative, weld seam thin and thick differs, and washes away cause tube wall thinning after welding through air water, reduces the service life of pipe.
Utility model content:
In order to solve the problem, the utility model is intended to propose a kind of small-bore welding clamp.
The technical solution of the utility model is: small-bore welding clamp, comprise left pincers handle and right pincers handle, left pincers with right pincers the structural member being Steel Sheet, left pincers handle and right pincers are connected middle part and shaft clearance, left pincers are provided with circlip with right pincers the axle two ends in outside, axle is wound with torsionspring, torsionspring both sides support arm be against respectively left pincers with right pincers on some positions of inner side, left pincers handle and right pincers form a semi-enclosed circular contour jointly upper inner, left pincers have operation window on the steel plate outside the semiclosed circular contour with right pincers handle, the left pincers handle on operation window top and right pincers are top attachment weld clearance gauge, weld seam clearance gauge extend into left pincers inboard with the semiclosed circular contour of right pincers handle.
The utility model has following beneficial effect: two pipes can be aligned by this device, and ensure weld size, can adjust the concordant degree of pipe, clamping is reliable, and have easy to operate, speed of application is fast, not by space constraint, welding quality high, favourablely promotes the use of.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is top views of accompanying drawing 1.
The left pincers handle of 1-in figure, 2-operation window, 3-weld seam clearance gauge, the right pincers handle of 4-, 5-torsionspring, 6-axle, 7-circlip.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2, small-bore welding clamp, comprise left pincers 1 and right pincers 4, left pincers are the structural member of Steel Sheet 1 and right pincers 4, left pincers are connected with axle 6 matched in clearance with right pincers 1 in the middle part of 4, left pincers are provided with circlip 71 and right pincers axle 6 two ends outside 4, axle 6 is wound with torsionspring 5, torsionspring 5 both sides support arm be against respectively left pincers 1 and right pincers on the some positions inside 4, left pincers form a semi-enclosed circular contour 1 and right pincers jointly 4 upper inner, left pincers have operation window 21 and right pincers on the steel plate outside the semiclosed circular contour of 4, the left pincers on operation window 2 top 1 and right pincers 4 top attachment weld clearance gauges 3, weld seam clearance gauge 3 extend into left pincers 1 and right pincers the semiclosed circular contour of 4 is inboard.
Two pipes can be aligned by this device, weld seam clearance gauge ensures weld size, and operation window is used for observing and welding, can adjust the concordant degree of pipe, clamping is reliable, and have easy to operate, speed of application is fast, not by space constraint, welding quality high, favourablely promotes the use of.
