Abstract
The utility model discloses a clamping device for a welded stud tensile test. The clamping device comprises a bottom plate and round steel fixedly connected with the bottom plate, wherein pressure plates and the bottom plate are fixedly connected through a bolt and a nut. Two planes of the pressure plates and the bottom plate are tightly contacted with the upper and lower planes of a test piece, respectively. Two pressure plates are respectively located on two sides of a weld joint. A manufacturing process device unit and system provided by the technical scheme have the advantages that firstly, the bottom plate and round steel are arranged, so that a downlink mechanism of a universal tester in test can conveniently clamp one end of a weldment; secondarily, the bottom plate is connected with the pressure plates through double-screw bolts and bolts, so that the clamping distance can be conveniently adjusted, thereby better clamping different weldments; finally, two pressure plates are arranged, so that the contact area of the pressure plates and the test piece can be conveniently adjusted, thereby reducing the slippery risk in the test process to the maximum extent.
Description
Technical field
The utility model relates to technical field of processing equipment, particularly a kind of welding screw tension test clamp device.
Background technology
At present, tension test is the reduction of area of measuring by the tension test of thickness of slab direction, and anti-lamellar tearing performance and the metallurgical imperfection of check, evaluation steel plate, be a very important technical parameter.Because the thickness of steel plate is not enough to directly be processed into tensile sample, therefore must be in connection extension, the two ends of sample, this part work just relates to the problem of welding.What adopt the earliest is arc welding, but this method heat input is inhomogeneous, and welding heat affected zone is large, and concentricity is also poor, seldom uses.Use now comparatively generally friction welding (FW), the method is to utilize the workpiece contact end face heat that phase mutual friction produces in relative rotary motion to make end reach thermoplasticity state, then a kind of solid-pase welding process that upset is realized rapidly, welding region is more even, and welding productivity is high.But this welding method is difficult to weld on-circular cross-section workpiece, welding machine one-time investment is larger, while only having production lot enough large, just can reach object cheaply.And that the maximum feature of this test is measured few frequency is exactly high, this can not embody the advantage of friction welding (FW).
At present welding technology is needed to tension test, obtain rank and diameter according to different weldments, select adaptive tension tester or universal testing machine.In ordinary test, require weldment can not move or slippage, if produce slippage, by causing the inaccurate of test figure, also cannot measure exactly accordingly.And some weldment is unfavorable for tension test, so, be necessary to design a kind of welding screw tension test clamp device.
Utility model content
In order to address the above problem, a kind of welding screw tension test clamp device is now provided, concrete technical scheme is as follows:
A kind of welding screw tension test clamp device, wherein, described clamp device includes base plate and the round steel being fixedly connected with base plate, and pressing plate is fixed and is connected by screw bolt and nut with base plate.
A kind of welding screw tension test clamp device, wherein, two planes of pressing plate and base plate are carried out upper and lower two plane close contacts with test specimen respectively.
A kind of welding screw tension test clamp device, wherein, described pressing plate is two, lays respectively at the both sides of weld seam.
Compared with prior art, a kind of manufacturing process device unit and system that technique scheme provides have the following advantages: by base plate round steel is set, in test, the descending mechanism of general-purpose testing machine can clamp one end of weldment very easily.Secondly, by double-screw bolt bolt connecting bottom board and pressing plate, clamping distance can be regulated easily, good clamping can be realized to different weldments.Finally, by two block pressur plates are set, can regulate easily the contact area of pressing plate and test specimen, reduce to greatest extent the risk of slippage in process of the test.

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of welding screw tension test clamp device structural representation providing in the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
1-threaded stud; 2-weld seam; 3-test specimen; 4-pressing plate; 5-base plate; 6-round steel; 7-bolt; 8-nut
As shown in Figure 1, the utility model arc stud welding tension test clamp device comprises base plate 5, round steel 6, pressing plate 4, screw bolt 7 and nut 8, the round steel 6 that base plate 5 is fixedly connected with base plate, pressing plate 4 is fixed and is connected by bolt 7 and nut 8 with base plate 5, pressing plate 4 is two, lay respectively at the both sides of weld seam 2, can regulate easily the contact area of pressing plate and test specimen, reduce to greatest extent the risk of slippage in process of the test.
This device is simple for production, easy to operate, and dependable performance more can be reused, and can apply the tension test with the welding screw of different size different materials.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
