For realizing the technical scheme that the purpose of this utility model adopts be:
Utilize vertical material stretch test machine to complete a clamping device for wire rope rupture test, comprise wedge-shaped jaw, the first grip block and the second grip block, after described the first grip block and the combination of the second grip block, match with described wedge-shaped jaw, the side that described the first grip block is relative with the second grip block is respectively arranged with the first groove and the second groove that xsect is circular arc, described the first groove is identical with the casting portion of sample with the shape after the second groove combination, after described the first groove and the second groove combination, clamp the casting portion of described sample, the position corresponding with the wire rope portion of described sample, outside of the first groove of described the first grip block is provided with the 3rd groove that xsect is circular arc, the position corresponding with the wire rope portion of described sample, outside of the second groove of described the second grip block is provided with the 4th groove that xsect is circular arc, after described the 3rd groove and the 4th groove combination, it is columniform through hole, described the first grip block is fixedly connected with described wedge-shaped jaw with fastening bolt by outer baffle respectively with the second grip block, interior docking port between described the first grip block and the second grip block and outer docking port stagger mutually and are parallel to each other.
The diameter of described through hole is greater than the diameter of described sample wire rope portion.
Described the first grip block is installed with fender with the second grip block with the end of the corresponding side of described sample casting portion.
Described the first grip block and the second grip block front are provided with the bolt hole for mounting knob.
The angle of closing between described the first grip block and the second grip block is 40 °.
Described the first grip block is fixedly connected with described fender with set bolt by web joint respectively with the second grip block.
Compared with prior art, the beneficial effects of the utility model are:
1, clamping device of the present utility model is by the structural design of two grip blocks, can meet the needs that the rear sample of major diameter steel wire rope casting is installed, and, while making to clamp sample, opening size sample just can being installed in less scope of support jaw, has overcome the little shortcoming of vertical cupping machine jaw size, is convenient to again adjust intuitively the position of casting sample, can load and unload fast test specimen, make vertical cupping machine can carry out the rupture test of large-specification wire rope.
2, clamping device of the present utility model is provided with the cylindrical hole structure by two groove combination two grip block inner sides, and the diameter of this through hole is greater than the diameter of wire rope portion, this structural design avoided adding on the one hand and held casting sample after steel wire contact with the direct of grip block, avoid due to the impact of the friction directly contacting on test findings, result is more reliable.Increase on the other hand the height of grip block stiff end, increased the friction force between wedge shape end face and the wedge-shaped jaw of grip block.
Accompanying drawing explanation
Figure 1 shows that the utility model utilizes vertical material stretch test machine to complete the schematic diagram of the clamping device of wire rope rupture test;
Figure 2 shows that the vertical view after the first grip block and the combination of the second grip block.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model utilize vertical material stretch test machine complete wire rope rupture test clamping device schematic diagram as depicted in figs. 1 and 2, comprise wedge-shaped jaw 1, the first grip block 2 and the second grip block 3, after described the first grip block 2 and the second grip block 3 combinations, match with described wedge-shaped jaw 1.The angle of closing between described the first grip block 2 and the second grip block 3 is preferably 40 °.Described the first grip block 2 side relative with the second grip block 3 is respectively arranged with the first groove 4 and the second groove 5 that xsect is circular arc, shape after described the first groove 4 and the second groove 5 combinations is identical with the casting portion 7 of sample, the casting portion 7 of the described sample of clamping after described the first groove 4 and the second groove 5 combinations, the position corresponding with 8 places of wire rope portion of described sample, the outside of the first groove 4 of described the first grip block 2 is provided with the 3rd groove 9 that xsect is circular arc, the position corresponding with 8 places of wire rope portion of described sample, the outside of the second groove 5 of described the second grip block 3 is provided with the 4th groove 10 that xsect is circular arc, after described the 3rd groove and the 4th groove combination, it is columniform through hole 6, described the first grip block 2 is fixedly connected with described wedge-shaped jaw 1 with fastening bolt 13 by outer baffle 12 respectively with the second grip block 3, interior docking port 14 between described the first grip block 2 and the second grip block and outer docking port 15 stagger mutually and are parallel to each other.
