Abstract
A kind of aluminium welding tank body air tight test frock, it includes cover plate, semi-ring clip, attachment bolt, sealing nut, nut, sealing ring, pull bar and guide ring, it is characterized in that: between upper and lower cover plate, be provided with pull bar and guide ring, sealed by sealing ring between upper cover plate and pull bar, side cover plate is provided with semi-ring clip and sealing ring, is fixed by attachment bolt and nut between casting tank body and side cover plate.The utility model has the advantage that this kind of part tooling can realize casting class tank body air-tight test before welding in assembling uses, ensure the air-tightness of integral solder tank body, more conventional traditional handicraft, carry out air tight test after welding, stop to do over again reprocess phenomenon because of what casting tank body gas leakage caused, reduce production cost.
Description
Technical field
The utility model relates to air tight test frock technical field, the air tight test frock of particularly a kind of aluminium welded tank.
Background technology
Owing to Shells of High Voltage Switches part needs to carry out air tight test to each part, Fig. 1 is at manufactured parts processed, this part two ends are casting tank body, middle for rolling wrought aluminium plate, tradition air tight test flow process is carried out after integral solder finishing, but due to the unstability of casting quality, cause inspection qualification rate low, need to block two ends casting tank body, reprocess, greatly reduce productivity ratio.Therefore seek to design the frock carrying out air tight test to two ends casting tank body before welding, the air-tightness to ensure postwelding part is qualified.
Content of the invention
The purpose of this utility model is to provide a kind of technical process rationally, and constant product quality is good, the high aluminium welding tank body air tight test frock of production efficiency.
The utility model is realized in, it includes cover plate, semi-ring clip, attachment bolt, sealing nut, nut, sealing ring, pull bar and guide ring, it is characterized in that: between upper and lower cover plate, be provided with pull bar and guide ring, sealed by sealing ring between upper cover plate and pull bar, side cover plate is provided with semi-ring clip and sealing ring, is fixed by attachment bolt and nut between casting tank body and side cover plate.
The utility model has the advantage that this kind of part tooling can realize casting class tank body air-tight test before welding in assembling uses, ensure the air-tightness of integral solder tank body, more conventional traditional handicraft, carry out air tight test after welding, stop to do over again reprocess phenomenon because of what casting tank body gas leakage caused, reduce production cost.
Brief description
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of aluminium welded tank air tight test frock.
Detailed description of the invention
As shown in Figure 1, this aluminium welding tank body air tight test frock includes upper cover plate 1,, lower cover the 2nd, side cover plate the 3rd, semi-ring clip the 4th, attachment bolt the 5th, sealing nut the 6th, nut the 7th, sealing ring the 8th, sealing ring 9, pull bar the 10th, guide ring the 11st, sealing ring 12 and casting tank body 13, it is provided with pull bar 10 and guide ring 11 between upper cover plate the 1st, lower cover 2, sealed by sealing ring 12 between upper cover plate 1 and pull bar 10, side cover plate is provided with semi-ring clip 4 and sealing ring 8, passes through attachment bolt 5 between casting tank body 13 and side cover plate 3 and nut 7 is fixed.
Upside before casting tank body 13 welding is roughing flange, and downside is bevel for welding, clamps sealing by the air tight test frock of aluminium welded tank to its overall carrying out.Inclined-plane, bevel for welding position seals, and utilizes groove contour localization, and ensures the fineness of seal request.Side roughing flange seal, flange surface non-bolt hole, clamp sealing frock with semi-ring clip 4.After frock assembling completes, inflatable interface is injected sulfur hexafluoride gas in tank body, then puts into tank body in sulphur hexafluoride leak detection equipment, detected whether gas leak phenomenon.If any gas leak phenomenon, special gas leak location device is used to detect concrete leak source position.
