Abstract
The utility model relates to a jig for welding a brass inner housing on a hot-galvanized outer casing of an explosion-proof blower, and the jig comprises two arc-shaped telescopic blocks, two adjusting nuts and an adjusting screw. The two adjusting nuts are fixedly connected with the inner cambered surfaces of the two arc-shaped telescopic blocks in the radial direction respectively, the directions of the internal threads of the two adjusting nuts are opposite, the directions of the external threads at the two ends of the adjusting screw are opposite, and the internal threads of the two adjusting nuts are matched with the external threads at the two ends of the adjusting screw respectively, so that the two arc-shaped telescopic blocks protrude outwards or retract inwards at the same time on the adjusting screw. The jig, with simple structure and convenient operation, can tightly clamp the brass inner housing on the inner wall of the outer casing of the explosion-proof blower by turning and rotating the jig according to the required angle and direction of rotation and screwing down the adjusting screw to enable the arc-shaped telescopic blocks at the two ends of the adjusting screw to expand and abut against the inner wall of the brass inner housing. The outer wall of the brass inner housing and the inner wall of the outer casing are contacted without clearance, which is helpful for improving the welding quality and the finished product rate of the hot-galvanized outer casing of the explosion-proof blower after welding.
Description
Technical field
The utility model relates to a kind of frock clamp, is specially adapted to the anchor clamps of hot galvanizing crust of explosion-proof fan welding brass inner sleeve.
Background technology
The brass inner sleeve of hot galvanizing crust of explosion-proof fan welding at present is to adopt support tools such as waddy, iron to withstand brass inner sleeve and blower housing, with brass inner sleeve every one week of 10～15cm spot welding, make it to be fixed on the inwall of blower housing, along the joint line that overlaps the machine shell that follows the wind in copper coin argon arc welding successively, deliver to the galvanizing workshop at last and reduce phlegm and internal heat zinc-plated.
Leave the gap between waddy, iron supporting brass inner sleeve and blower housing, welding stress is big, easily weld seam is pulled out crackle, causes the crack and plays the drum phenomenon.Follow-up pickling and clear water are washed in the process of workpiece, and a large amount of moisture content infilter in copper coin and the blower housing inwall gap from the sand, pore and the weld crack that produce.After the workpiece cleaning, leave a large amount of moisture content between copper coin and blower housing, in the time of in being dipped into 400～500 ℃ zinc solution, moisture content runs into 400～500 ℃ of zinc solutions will become water vapour, expand immediately and explode, zinc solution easily enters expanded drum in the gap of copper coin and blower housing, the serious workpiece that makes is scrapped, and slight also can become the crack with weld seam, even if zinc-plated again after doing over again, the quality of product also can not get guaranteeing, yield rate is low, increases production cost, and easily produces pernicious gas when doing over again repair welding, environmental pollution is serious, and operating personnel's safety can not get ensureing.
Summary of the invention
Use waddy, iron that interior cover is withstood on the blower housing inwall when in the welding of blower housing inwall, overlapping in the prior art in order to solve, operation inconvenience, welding stress is big, welded seal is poor, there are weld seam, crack, shortcomings such as not prison welding is solid, the purpose of this utility model provides a kind ofly is convenient to welding operation, can be seamlessly with interior cover swelling in the blower housing inwall, welding stress is little, welded seal is good, the anchor clamps of no gap, welding back, flawless hot galvanizing crust of explosion-proof fan welding brass inner sleeve.
The technical solution adopted in the utility model is: the anchor clamps of a kind of hot galvanizing crust of explosion-proof fan welding brass inner sleeve: comprise two arcs stretch piece, two adjusting nuts, an adjusting screw(rod), the intrados of two flexible pieces of arc is radially fixedly connected adjusting nut respectively, the internal thread direction of two adjusting nuts is opposite, the two ends external screw thread direction of adjusting screw(rod) is opposite, and the internal thread of two adjusting nuts cooperates with the external screw thread at adjusting screw(rod) two ends respectively to make and is radially protruding simultaneously on the flexible piece adjusting screw(rod) of two arcs or inside indentation state simultaneously.This clamp structure is simple, easy to operate, only need the rotation adjusting screw(rod) to make the arc anchor clamps break away from the blower housing inner chamber, or screw in the other direction the flexible piece of arc that adjusting screw(rod) makes the adjusting screw(rod) two ends with brass inner sleeve swelling blower housing inwall, reach the brass inner sleeve outer wall and the blower housing inwall fits tightly gapless purpose.
Further, the arc and the blower housing inner wall shape of the flexible piece of described arc are coincide, and the fan-shaped angle of the flexible piece of arc is 30 °～180 °.During clamp operation, brass inner sleeve contacts no gap with the blower housing inwall, can effectively improve welding quality, has improved the yield rate of welding back hot dip galvanizing process indirectly.
Again further, the fan-shaped angle of the flexible piece of preferred arc is 90 °, presses the fan-shaped angle of the extrados of the flexible piece of arc and can establish by factors such as brass inner sleeve size, welding requirements.On the flexible piece swelling brass inner sleeve of arc, following running-on is in the formation of blower housing inwall, following joint line is the circular arc of quarter turn, to on this, following joint line place carries out the mode of continuous welding synchronously in the same way and welds in turn, unclamp the flexible piece of arc and clamp brass inner sleeve clockwise or after being rotated counterclockwise 90 °, after welding one section in turn displacement arc anchor clamps carry out the welding of next 1/4 circular arc welding bay, finish whole circumference until welding, finish the welding operation of whole circle need only divide four times successively rotation fix to clamp brass inner sleeve and weld and get final product, cause the welding deviation when having avoided the clamping number of times too much or very few, effectively reduce welding stress, guarantee welding quality, and operating procedure is few, helps to increase work efficiency.
The utility model is simple in structure, easy to operate, tighten adjusting screw(rod) by institute's palpus direction of rotation, angle after pulling rotation, can make the extrados swelling copper sheathing inwall of the flexible piece of arc at adjusting screw(rod) two ends, reach, be convenient to welding operation the effect of brass inner sleeve swelling in the blower housing inwall, and the brass inner sleeve outer wall does not have the gap with the blower housing inwall and contacts, the welding quality height, the yield rate height more can adapt to the instructions for use under the adverse circumstances of blast protection, anti-seawater corrosion and other easy-to-rusts.
