Abstract
The invention provides a central part needle cylinder fixing device of a polyester capacitor winding machine, wherein the central part needle cylinder fixing device comprises a bolt and a nut, wherein the bolt penetrates through a rack of the winding machine and a needle cylinder main body; the nut is screwed to the bolt and is used for fixing the rack of the winding machine and the needle cylinder main body; the nut is provided with at least one splicing groove which penetrates through the outer side wall and inner side wall of the nut; and the splicing groove is internally provided with a splicing sheet which is spliced with a thread on the bolt. The needle cylinder can be firmly fixed on the polyester capacitor winding machine, and has less possibility of dropping off; the influence on the manufacturing accuracy of a polyester capacitor is avoided; the rejection rate of the polyester capacitor is reduced; and the working efficiency is improved.
Description
Technical field
The present invention relates to polyester electric capacity manufacture field, be specifically related to the central part syringe fixing device of polyester electric capacity up-coiler.
Background technique
The permittivity of polyester electric capacity is higher, and volume is little, and capacity is big, and stability is better, and the suitable shunt capacitance of doing is used in individual various direct currents or the moving circuit of medium and low frequency.The precision of polyester electric capacity, loss angle, insulation resistance, temperature characteristic, reliability and index such as conform all are superior to electrochemical capacitor, these two kinds of electric capacity of ceramic disc capacitor.Polyester electric capacity is done electrode with two metal foils, is clipped in as thin as a wafer in the insulating medium, is rolled into cylindrical or flat cylindricality fuse, and medium is a terylene.In the manufacture process of polyester electric capacity, need use polyester electric capacity up-coiler; The central part of polyester electric capacity up-coiler is provided with the syringe that metal foil or metal needle are provided, and utilizes screw that syringe is fixed on the central part of polyester electric capacity up-coiler usually, because polyester electric capacity up-coiler can produce vibration in the course of the work; Screw also can and then unclamp from screw hole along with vibration; Make that fixing of syringe is not firm, and then influence the accuracy of manufacturing of polyester electric capacity, cause the scrappage of polyester electric capacity to raise; Then need the workman to carry out craft to screw, reduced working efficiency in order to fix.
Summary of the invention
Technical problem to be solved by this invention is to provide the central part syringe fixing device of polyester electric capacity up-coiler; Can make the syringe firm fixation on polyester electric capacity up-coiler; Be difficult for dropping; Avoid the accuracy of manufacturing of polyester electric capacity is exerted an influence, reduce the scrappage of polyester electric capacity, increase work efficiency.
For solving above-mentioned existing technical problem; The present invention adopts following scheme: the central part syringe fixing device of polyester electric capacity up-coiler; Comprise the bolt of cross-under on up-coiler frame and syringe main body, be screwed in the nut that is used for fixing up-coiler frame and syringe main body on the bolt; Said nut is provided with at least one inserting groove that runs through nut outer side wall and madial wall, be provided with in the said inserting groove with bolt on the screw thread insert-connecting plate of pegging graft.
As preferably, said inserting groove adopts and is symmetricly set on two on the nut, and said insert-connecting plate adopts two, and correspondence is plugged in the inserting groove.Prevented that effectively nut and bolt from relatively rotating, made between syringe and the polyester electric capacity up-coiler fixed.
As preferably, the inboard that is positioned at nut on the said bolt is provided with packing ring.Protected the surface of connected piece not abraded by nut effectively, disperseed the pressure of nut connected piece.
As preferably, said insert-connecting plate adopts copper structure.Easily manufactured, be difficult for distortion.
Beneficial effect:
The present invention adopts technique scheme that the central part syringe fixing device of polyester electric capacity up-coiler is provided, and makes the syringe firm fixation on polyester electric capacity up-coiler, is difficult for dropping; Avoided the accuracy of manufacturing of polyester electric capacity is exerted an influence; Reduced the scrappage of polyester electric capacity, since fixed between nut and the bolt, be difficult for unclamping; Need not the craft that the workman carries out after nut unclamps again and screw, improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; The central part syringe fixing device of polyester electric capacity up-coiler; Comprise the bolt 3 of cross-under on up-coiler frame 1 and syringe main body 2, be screwed in the nut 4 that is used for fixing up-coiler frame 1 and syringe main body 2 on the bolt 3; Said nut 4 is provided with at least one inserting groove 5 that runs through nut 4 outer side walls and madial wall, be provided with in the said inserting groove 5 with bolt 3 on the screw thread insert-connecting plate 6 of pegging graft.Said inserting groove 5 adopts and is symmetricly set on two on the nut 4, and said insert-connecting plate 6 adopts two, and correspondence is plugged in the inserting groove 5.The inboard that is positioned at nut 4 on the said bolt 3 is provided with packing ring 7.Said insert-connecting plate 6 adopts copper structure.
During actual the use, after nut 4 is tightened, insert-connecting plate 6 is inserted in the inserting groove 5; Get final product with the screw thread grafting on the bolt 3, prevented that effectively nut 4 and bolt 3 from relatively rotating, and makes the syringe firm fixation on polyester electric capacity up-coiler; Be difficult for dropping, avoided the accuracy of manufacturing of polyester electric capacity is exerted an influence, reduced the scrappage of polyester electric capacity; Because it is fixed between nut 4 and the bolt 3; Be difficult for unclamping, need not the craft that the workman carries out after nut 4 unclamps again and screw, improved working efficiency.
