Description
Technical field
The utility model belongs to foundry goods lab-size equipment, particularly a kind of pressure test universal latch clamping tool.
Background technology
In high pressure aluminium alloy casting industry, each foundry goods will carry out the hydraulic testing and air-tight test, traditional way is manually to utilize bolt, nut, pad that thick and heavy test cover plate is fixed on the flange of each foundry goods, the fastening bolt of Kong Douxu on each flange, sometimes because bolt strained inequality causes leakage, also need again fasteningly, and have certain difficulty in cover plate lifting and assembling process, and easily scratch tested foundry goods.In addition, because the hole reference circle on foundry goods is in different size, just need the different cover plate of preparation, make experiment work very complicated, work efficiency is also low, wasting manpower and material resources.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, easy to operate, the pressure test universal latch clamping tool of increasing work efficiency.
The technical scheme that the utility model technical solution problem adopts is: pressure test universal latch clamping tool comprises base, general cover plate, hydraulic jack, top board, be characterized on base the even distance of circumferential edges 120 degree be welded and fixed three above threaded ladder column, on the connection of thread step above three ladder columns, install general cover plate, at the center of general cover plate fixing dress hydraulic jack, above hydraulic jack, the thread segment of ladder column installs top board, the screw threads for fastening of set nut and packing ring and ladder column for top board, testpieces is loaded in three ladder columns above base, below the connection universal cover plate of top.
The beneficial effects of the utility model are: pressure test universal latch clamping tool is simple in structure, can be to testpieces fast-holding, and coverplate stress is even, test effect is good, increase work efficiency, avoid the scuffing of testpieces, reduce people the duplication of labour, use manpower and material resources sparingly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is pressure test universal latch clamping tool structural drawing.
In figure, 1-set nut; 2-packing ring; 3-top board; 4-hydraulic jack; 5-general cover plate; 6-ladder column; 6-1-screw thread; 7-testpieces; 8-base.
Embodiment
Embodiment, with reference to accompanying drawing 1, pressure test universal latch clamping tool is to be welded and fixed three ladder columns 6 in the circular base 8 upper edge place even distances of 120 degree, on ladder column 6, be provided with screw thread 6-1, on the step of the screw thread 6-1 above three ladder columns 6, install general cover plate 5, at the center of general cover plate 5 fixing dress hydraulic jack 4.Above hydraulic jack 4, the screw thread 6-1 section of ladder column 6 installs top board 3, top board 3 use set nuts 1 and packing ring 2 are fastening with the screw thread 6-1 of ladder column 6, testpieces 7 is loaded in base 8 three ladder columns 6 above, below the top connection universal cover plate 5 of testpieces 7.
The course of work of pressure test universal latch clamping tool is: the testpieces 7 that assembles sealing ring is positioned over to the center on base 8 according to flange excircle mark by testpieces 7, general cover plate 5 is positioned on another end face of flange, lifting jack 4 is positioned over to general cover plate 5 centers, top, top board 3 is positioned over to lifting jack 4 tops by screw thread 6-1 location, with set nut 1 and packing ring 2 lockings, regulate lifting jack 4 that testpieces 7 is compressed, get final product pressure test.
