Description
Technical Field
The utility model relates to an electrical engineering material quality detection device especially relates to a special fixture towards single perpendicular burning of wire and cable.
Background
The wire and cable is a wire product for transmitting electricity, magnetic energy and information and realizing electromagnetic energy conversion, is widely applied to national production and life, has a key effect on the safety of national production and life, and is one of the most important detection means for the safety of the wire and cable in the prior art in a vertical combustion experiment of a single wire and cable.
According to the current national standard, before the flame vertical spreading test of a single insulated wire and cable is started, a sample is straightened, fixed on two horizontal brackets by using a proper copper wire and vertically placed in a test metal cover for testing. In an actual test site, the wire and cable are wound into a bundle when leaving a factory, have a certain radian and curvature, are not easy to straighten before the test, are not clamped on a clamp of an instrument and can be bent due to the properties of the material such as the plastic elasticity of the wire and cable, and the length of a test object is difficult to determine in a bent state; the clamp of the instrument can move up and down, back and forth, the screw needs to be screwed up manually during clamping, repeated measurement and adjustment on the instrument are needed to achieve the specification of the position of the sample in the standard, and the test time is delayed. Therefore, the special fixture for vertical combustion of a single wire and cable is researched, the length fixing and straightening before the wire and cable test are facilitated, the detection efficiency is improved, and the special fixture has important significance.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a special fixture towards single perpendicular burning of wire and cable, this anchor clamps can realize wire and cable's fixed length and alignment work before experimental fast, reduce manual operation step time, improve test efficiency.
The purpose of the utility model is realized through the following technical scheme:
a special clamp facing to vertical combustion of a single wire and a single cable comprises a fixed-length supporting straight rod (101), an alignment fixing clamp (102), an alignment movable clamp (103) and a fixed-length fixing knob (104); the fixed-length supporting straight rod (101) is connected with the straightening fixing clamp (102); the straightening movable clamp (103) is in clearance fit with the fixed-length supporting straight rod (101) through the shaft hole and can slide up and down on the fixed-length supporting straight rod (101) to clamp the tail end of the cable and realize straightening; the fixed-length fixing knob (104) is connected with the straightening fixing clamp (102), the straightening movable clamp (103) is fixed at the designated position of the fixed-length supporting straight rod (101) through rotating fixed length, and the fixed length of the electric wire and the electric cable is realized through the straightening movable clamp (103).
Compared with the prior art, the utility model discloses an advantage can have as follows to one or more embodiments:
can once only accomplish fixed length and correction work before the perpendicular burning of wire and cable experiment, special fixture is rational in infrastructure, the practicality is strong, the flexibility is good, because fixed length and correction that the winding packing that dispatches from the factory of wire and cable caused are inconvenient when effectively solving current wire and cable perpendicular burning experiment, reduce manual operation step time, improve test efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1, the special fixture for vertical combustion of single electric wire and cable has an integral structure, which comprises a fixed-length supporting straight rod 101, an alignment fixing clamp 102, an alignment movable clamp 103 and a fixed-length fixing knob 104; the fixed-length supporting straight rod 101 is connected with the straightening fixing clamp 102; the straightening movable clamp 103 is in clearance fit with the fixed-length supporting straight rod 101 through the shaft hole, can slide up and down on the fixed-length supporting straight rod 101, and is used for clamping the tail end of the cable and realizing straightening; the fixed-length fixing knob 104 is connected with the straightening fixing clamp 102, and the straightening movable clamp 103 is fixed at the designated position of the fixed-length supporting straight rod 101 by rotating fixed length, so that the fixed length of the electric wire and the electric cable is realized by the fixed-length fixing knob and the straightening movable clamp 103.
The fixed length straight supporting rod 101 is provided with length scales.
The working process of the embodiment is as follows:
①, selecting the needed test length scale on the fixed length support straight rod, ② adjusting the clamp, moving the alignment movable clamp to the corresponding scale, rotating the fixed length fixing knob to fix the position of the alignment movable clamp, ③ clamping the sample, cutting the tested wire and cable with the length larger than the needed test length as the sample, clamping one end of the tested wire and cable at the position 5cm away from the fixed length support straight rod by the alignment fixed clamp, straightening the sample along the direction of the support straight rod, clamping the other end of the tested wire and cable at the position 5cm away from the fixed length support straight rod by the alignment movable clamp, cutting the redundant sample, ④ testing, clamping the clamp in the testing device, and carrying out the test.
Although the embodiments of the present invention have been described above, the description is only for the convenience of understanding the present invention, and the present invention is not limited thereto. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
