Description
Technical Field
The invention belongs to the technical field of bundle wire detection, and particularly relates to a detection device for the stranded outer diameter of a bundle wire.
Background
In a laboratory, it is often necessary to detect and calibrate the stranded outer diameter of the bundle wires to obtain corresponding experimental data or to achieve the purpose of sampling and investigation of the current batch of bundle wires. The outer wall of a single wire is smooth, and is easy to measure by using a vernier caliper and the like, and the stranded outer diameter of a bundle wire formed by clockwise or anticlockwise stranding a plurality of wires is often extremely irregular in cross section, so that the detection is difficult. At present, if finished product detection is performed, the finished product detection can be generally replaced by an insulation inner diameter, namely, an insulation section is cut, and then a microscope is adopted to measure the insulation inner diameter. If the measurement is carried out in the production process, some of the measurement is carried out by devices such as vernier calipers, but only a certain point can be clamped, and meanwhile, the measurement data is often smaller due to the irregular shape of the wire bundles; there are also methods of directly installing on-line measuring equipment on a production line to perform on-line measurement, but the wire diameter measurement value is large due to tension. The inaccuracy of the measurement data exists in the above varieties, so that a plurality of adverse effects are brought to the normal detection flow for judging whether the current batch of the wire bundles are qualified or not in the later period; in addition, the strand wires have different twisting directions and different twisting directions, and also exist as experimental data and judging references, so that experimenters are required to further judge the strand wires by special visual observation; the whole judging process is time-consuming and labor-consuming, and for some small-diameter tows, a severe test is provided for the eyes of experimental staff, and the problem needs to be solved.
Disclosure of Invention

In order to achieve the above purpose, the present invention adopts the following technical scheme:
a detection device for bundle silk transposition external diameter, its characterized in that: the air duct restraining device comprises a base, a fan arranged on the base and an air duct with a plumb axis on an air outlet path of the fan, wherein a duct cavity of the air duct forms an air duct for restraining the air outlet direction of the fan; the wire bundling barrel is internally provided with wire bundling to be tested, the length direction of which is consistent with the axial direction of the wire bundling barrel after being straightened; the detection device also comprises a detection impeller for detecting the twisting outer diameter and/or twisting direction of the bundle wire to be detected, wherein a die hole for the bundle wire to be detected to pass through is axially formed in the hub of the detection impeller in a penetrating manner, and the aperture of the die hole is consistent with the standard twisting outer diameter of the bundle wire to be detected; a fan which is used for blowing the detection impeller and enabling the detection impeller to generate unidirectional spin and lifting actions from bottom to top is arranged under the detection impeller; the beam wind cylinder is a transparent cylinder or a cylinder body is provided with an observation window capable of observing the environment in the cylinder.
Further, an L-shaped fixing frame is arranged on the base, the bottom end of a plumb section of the fixing frame is fixed on the upper plate surface of the base, and a horizontal section of the fixing frame forms a fixing part for fixing the beam wind cylinder; and the horizontal section and the base are respectively provided with a group of clamps, so that the two ends of the bundle wire to be tested are clamped and straightened.
Furthermore, a squirrel-cage underframe is arranged on the upper plate surface of the base; the fan is positioned in the underframe and is used for exhausting air through an air hole positioned at the top end of the underframe; a group of clips are arranged at the top end of the underframe, and the arrangement positions of the clips and the arrangement positions of the wind holes are spatially avoided from each other.
Further, a through hole is formed in the horizontal section of the fixing frame, so that an air outlet of the beam air duct is formed.
Further, the underframe, the fan, the wire bundle to be detected, the detection impeller and the wire bundle wind cylinder are coaxial with each other.
Further, the hub comprises an outer hub body sleeved with each other and an inner detachable die arranged in the outer hub body, and the inner die and the outer hub body are fastened with each other through axial positioning screws arranged at the top end face of the hub.
The invention has the beneficial effects that:
1) The invention provides a special device for detecting the stranded outer diameter of the bundle wire, which solves a plurality of defects caused by the traditional online measurement or vernier caliper measurement, so that the purpose of conveniently and schematically detecting the stranded outer diameter and even the stranded direction of the bundle wire can be realized based on the existing bundle wire.
Specifically, during actual operation, under the premise that the wire to be detected is straightened in the wire bundling barrel, the detection impeller sleeved on the wire to be detected and provided with the standard die hole rotates through the air blowing from bottom to top of the fan, so that the spin-up action is generated, and the aim of conveniently judging the twisting outer diameter and the twisting direction of the current wire to be detected is finally achieved. The judging method comprises the following steps: when both the twisting outer diameter and the twisting direction meet the standards, the detection impeller can smoothly rotate and rise. When the twisting outer diameter meets the standard and the twisting direction is not, the rotation of the impeller is detected to have obvious jerk and slow rise. When the twisting outer diameter does not meet the standard, the detection impeller cannot rise. Obviously, the whole flow can be observed through the beam air duct, the steps are clear, the detection efficiency is extremely high, and the method is particularly beneficial to sampling investigation occasions in a laboratory.

Detailed Description
For ease of understanding, the specific implementation of the present invention, as well as the workflow, is further described herein with reference to FIGS. 1-2:
the specific implementation structure of the invention is shown with reference to fig. 1-2, and the main structure of the invention comprises a base 10, a fixing frame 50, a beam wind barrel 30, a fan 20, a clamping 60 and a detection impeller 40. Wherein:
the base 10 and the fixing frame 50 are combined to form an external fixing frame for realizing reliable fixing of the fan 20, the clamping 60 and the beam duct 30. In actual assembly, referring to fig. 1, a fixing frame 50 extends vertically upward from the base 10, and a beam duct 30 with a vertically arranged axis is suspended from a horizontal section of the fixing frame 50. The bottom opening of the beam wind barrel 30 is opposite to the squirrel-cage underframe 11 on the upper plate surface of the base 10. The fan 20 is arranged in the underframe 11, and wind generated by the fan at the fan 20 can enter the beam wind cylinder 30 along the wind hole 12 at the top end surface of the underframe 11, so that the uniform lifting function of the detection impeller 40 is achieved.
The outer shape of the sensing impeller 40 is shown with reference to fig. 2, which is in fact a single-turn impeller configuration, including hubs and blades. In operation, the hub is divided into an inner mold 41a and an outer hub 41b so that the inner mold 41a can be replaced adaptively according to the standard stranded outer diameter of the current wire harness to be tested. After the inner mold 41a is selected, the inner mold 41a is inserted and fixed to the outer hub 41b by the axial set screw 41c as shown in fig. 2.
When the detecting impeller 40 goes up along the straightened wire harness, the detecting impeller 40 generates spin; the spinning action not only can be used for detecting whether the twisting direction of the wire bundle a to be detected is reasonable, but also can synchronously achieve the purpose of carrying out standardized detection on the outer diameter of the wire bundle a to be detected in a self-balancing and comprehensive mode when spinning in the same direction with the twisting direction. In other words, when the bundle wire is manufactured, the wires have irregularities in the circumferential direction due to the tightness degree after the wires are twisted, which is one of the main factors that cause the difference in the measurement results in the bipolar differentiation; by detecting the spin of the impeller 40, the wire bundle a to be detected can be measured circumferentially and axially without dead angles, and the detection effect is excellent.
The detecting impeller 40 can be divided into a forward rotating impeller and a reverse rotating impeller during actual operation so as to match the S direction and the Z direction of the bundle wire a to be detected; thus, when the rotation direction of the detecting impeller 40 is opposite to the twisting direction of the bundle wire a to be detected, a visual frustration is naturally generated. In practice, the detection impeller 40 of the present invention employs a spin-up from bottom to top, rather than a self-weight-down structure, and is considered to avoid the influence of the self weight of the detection impeller 40 on the detection result as much as possible. The wind lifting of the fan 20 has the characteristics of softness, uniform speed and controllability, and meanwhile, even if the detecting impeller 40 is slightly blocked in the middle, the detecting impeller is extremely easy to be observed by naked eyes through the beam wind barrel 30; compared with uncertainty of gravity falling and difficulty in observability caused by instant descending, the wind power lifting method provided by the invention has the advantages that the experimental efficiency, the detection accuracy and the operation stability can meet the experimental requirements.
In addition, the wire bundle a to be measured is necessarily tight, whether in the conventional or the measuring mode of the invention. The clamping device adopts the clamping device 60 to clamp the bundle wire a to be detected at two ends, and ensures the straightness of the bundle wire a to be detected in the detection process in a mode of tightening and then clamping; the clip 60 may be a commercially available wire clip or the like, and will not be described in detail herein.
