The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Consult Fig. 1 to Fig. 2, a kind of coreless wire coil precise winding machine comprises bus cable device and Winder; Described Winder comprises drum 5, fixing device 6 and actuating device 7, and actuating device 7 drives by the drum 5 after fixing device 6 clampings and rotates; Described drum 5 is provided with the taper shaft core 50 that can rise, and second flange 52 of its less side in taper shaft core cross section and 50 detachable connections of taper shaft core.After the finished product wire rod was finished processing, fixing device 6 unclamped drum 5, and drum 5 can be dismantled, and made it to separate with the finished product wire rod.The finished product wire rod can be given subsequent user through shrink-wrap, need not to take the dish tool, saves production cost and the use cost of follow-up support.
Describe the structure of drum 5 below in detail, consult Fig. 3 to Fig. 5, the described taper shaft core 50 that rises is made up of cylindrical central sleeve 500, connecting rod 501 and three blocks of cone plates 502; Cylindrical central sleeve 500 is captiveed joint with first flange 51; First flange 51, second flange 52 are provided with orientational cone-shaped surface (510,520), the cone plate 502 corresponding orientational cone-shaped surfaces (5020,5021) that are provided with; Cone plate 502 flexibly connects by two connecting rods 501 and cylindrical central sleeve 500, pieces together the taper coiling face of taper shaft core 50; Its orientational cone-shaped surface (5020,5021)) corresponding orientational cone-shaped surface (510,520) with first flange 51, second flange 52 cooperates the moving sets that forms the energy slide relative.First flange 51 and second flange 52 are respectively equipped with position-limited trough (511,521), and under the general assembly state, the two ends of cone plate 12 embed in the corresponding position-limited trough (511,521).
Present embodiment, first flange 51, taper shaft core 50 and second flange 52 are connected by screw rod 53, and the described screw rod 53 corresponding nuts 54 that pass first flange 51, taper shaft core 50 and be arranged on second flange 52 are connected.Described nut 54 is provided with stop spring 540 for the aligning nut, and the two ends of this spring 540 offset with the outer ring 541 and the inner ring 542 of aligning nut respectively.By aligning nut 54 is set, has improved the setting accuracy of first flange 51, taper shaft core 50 and second flange 52, but also simplified the assembly difficulty of drum.
As preferred embodiment, also be provided with aligning thrust bearing 55, this bearing 55 is arranged between the bottom surface of screw rod mounting hole 512 of the nut of described screw rod 54 and first flange 51.Under the effect of aligning thrust bearing 55, reduced and tightened screw rod 53 needed moments of torsion, alleviate manipulation strength; Match with aligning nut 54 on the other hand, realize accurate in locating.
Cylindrical central sleeve 50 and second flange, 52 corresponding locating dowel pin 503 and the knock holees 522 of being provided with.When assembling, cone axis core 50 and second flange, 52 Primary Location make things convenient for next step installation like this.
Also be provided with extension spring 56, the two ends of this extension spring 56 are connected with cylindrical central sleeve 50 with cone plate 502 respectively.When drum split, the extension spring 56 pulling cone plates 502 and first flange 51 were subjected to displacement, and make cone axis core 50 reduced diameter, and the finished product wire rod is separated with cone axis core 50.
It is as follows that the utility model splits structural analysis: first flange 51 by 8 connecting rods 501 with three independently cone plate 502 be connected, wherein first flange 51 contacts by the conical surface with cone plate 502 and can form the moving sets that slides up and down.When the drum receipts expire wire product, unclamp screw rod 53, sling first flange 51 and taper shaft core 50, cone plate 502 is subjected to displacement with first flange 51 down because of deadweight and the effect of stretching spring 56, cone axis core 50 reduced diameter of cone plate 502 combinations, cone axis core 50 separates with the wire rod and second flange 52.
In drum when combination,, the position pin 503 of cone axis core 50 by cylindrical central sleeve 500 cooperates the location with the knock hole 522 of second flange 52; Three blocks of cone plates 12 cooperate the taper coiling face that pieces together the taper shaft core by orientational cone-shaped surface, and further utilize the location ring shaped slot 521 of second flange 52 spacing, guarantee drum overall dimensions and precision; Tightening screw rod 53 at last gets final product.
