Description

[0001] The utility model relates to the technical field of superconducting wire production, in particular to a length measuring device for superconducting wires. Background Art

[0002] Superconducting wires are made of superconducting materials and can carry high-density currents under strong magnetic fields.

[0003] During the weaving production process of superconducting wires, the same type of superconducting wire is usually produced continuously at one time through production equipment to improve work efficiency.

[0033] In the utility model, the larger the diameters of the clamping wheel 18 and the measuring wheel 22 connected at the ends of the first connecting rod 16 and the second connecting rod 26, the shorter the lengths of the first connecting rod 16 and the second connecting rod 26; the surface of each first connecting rod 16 and the second connecting rod 26 is respectively provided with a first positioning hole 17 and a second positioning hole 27, and the surfaces of the positioning plate 8 and the side plate 5 are provided with through holes at positions corresponding to the first positioning holes 17 and the second positioning holes 27, and the corresponding first positioning holes 17 and the through holes and the second positioning holes 27 and the through holes are fixedly connected by positioning pins.

[0035] In the present invention, the connection between the first telescopic rod 15 and the positioning plate 8 and the connection between the second telescopic rod 25 and the side plate 5 are both provided with a size adjustment knob 21.

The display screen 9 integrates a CPU processing module, and according to the different rotation numbers of the measuring wheel 22 with different diameters measured by the counting sensor 10, the length of the superconducting wire with different diameters after passing through the length measuring mechanism 14 and the clamping mechanism 13 is calculated, thereby completing the length measurement of the superconducting wire.

[0038] In the present invention, moving wheels 28 are arranged at the four corners of the bottom of the bottom plate 1 .

[0039] Embodiment: The length measuring mechanism 14 and the pressing mechanism 13 as well as the guiding mechanism and the limiting mechanism are selected with corresponding sizes according to the diameter size of the superconducting wire. Taking the superconducting wire with the minimum diameter size that the device can meet as an example, when in use, the superconducting wire is first passed through the limiting groove 24 between the guide rollers 7 of corresponding sizes and on the surface of the limiting roller 12 from right to left, and then the length measuring mechanism 14 and the clamping mechanism 13 are adjusted. When adjusting, the corresponding first positioning hole 17 and the positioning pins between the through hole and the second positioning hole 27 and the through hole are first removed, and then the measuring wheel 22 and the clamping wheel 18 that match the diameter size of the superconducting wire are adjusted by the size adjustment knob 21 to rotate to the side close to each other, and the first connecting rod 16 and the second connecting rod 26 are fixed by the positioning pins in conjunction with the first positioning hole 17 and the second positioning hole 27, and then the positions of the measuring wheel 22 and the clamping wheel 18 that match the diameter size of the superconducting wire are fixed, and at the same time, the second telescopic rod 25 connected to the length measuring mechanism 14 is telescoped to the longest state, that is, the three-stage telescopic structure is fully extended, and the first telescopic rod 15 connected to the clamping mechanism 13 is retracted to the shortest state, that is, the three-stage telescopic structure is fully retracted. At this time, the measuring wheel 22 on the length measuring mechanism 14 and the pressing wheel 18 on the pressing mechanism 13 are in the same straight line in the longitudinal direction, and are in the same straight line with the smallest limiting groove 24 in the transverse direction, which can ensure that the superconducting wire can pass between the measuring wheel 22 and the pressing wheel 18 after passing through the smallest limiting groove 24, and then pass between the limiting groove 24 on the surface of the limiting roller 12 symmetrically arranged on the left and right sides of the side plate 5 and the guide roller 7. At the same time, the annular protrusion 23 on the surface of the measuring wheel 22 and the pressing groove 19 on the surface of the pressing wheel 18 are connected with each other, which can not only press the superconducting wire, but also transport the superconducting wire forward from right to left. And during the rotation of the measuring wheel 22, the counting sensor 10 counts the number of revolutions of the measuring wheel 22 and sends the number to the display screen 9 through an electrical connection. The display screen 9 has an integrated CPU processing module, which calculates the lengths of superconducting wires of different diameters after passing through the length measuring mechanism 14 and the clamping mechanism 13 according to the different number of revolutions of the measuring wheels 22 of different diameters, thereby completing the length measurement of the superconducting wire.

[0040] When adjusting the measuring wheel 22 and the clamping wheel 18 according to the different diameters of the superconducting wire, it is not only necessary to adjust the measuring wheel 22 and the clamping wheel 18 that match the diameter of the superconducting wire to rotate to the side close to each other through the size adjustment knob 21, but also necessary to adjust the second telescopic rod 25 and the first telescopic rod 15 connecting the measuring wheel 22 and the clamping wheel 18 according to the positions of different limit grooves 24. The following four situations are met during adjustment: one: the second telescopic rod 25 connected to the length measuring mechanism 14 is telescoped to the longest state, that is, the three-stage telescopic structure is fully extended, and the first telescopic rod 15 connected to the clamping mechanism 13 is retracted to the shortest state, that is, the three-stage telescopic structure is fully retracted; two: the length measuring mechanism 14 is connected The second telescopic rod 25 of the embodiment is in the second telescopic state, that is, the second section of the three-stage telescopic structure is fully extended, and the first telescopic rod 15 connected to the clamping mechanism 13 is in the first telescopic state, that is, the first section of the three-stage telescopic structure is fully extended; three: the second telescopic rod 25 connected to the length measuring mechanism 14 is in the first telescopic state, that is, the first section of the three-stage telescopic structure is fully extended, and the first telescopic rod 15 connected to the clamping mechanism 13 is in the second telescopic state, that is, the second section of the three-stage telescopic structure is fully extended; four: the second telescopic rod 25 connected to the length measuring mechanism 14 is retracted to the shortest state, that is, the three-stage telescopic structure is fully retracted, and the first telescopic rod 15 connected to the clamping mechanism 13 is retracted to the longest state, that is, the three-stage telescopic structure is fully extended. The first telescopic rod 15 and the second telescopic rod 25 are both three-stage telescopic structures, and the length of each stage of the telescopic structure is the same as the length between adjacent limit slots 24, so after adjustment, the four situations can correspond to limit slots 24 of different sizes respectively.
