Description
Technical field
The utility model relates to a kind of transformer production processing unit (plant), is specifically related to a kind of draw drum fixture.
Background technology
Transformer is one of nucleus equipment of power network, therefore requires very high to the safety and stability of transformer, not only requires that transformer electric property is reliable, simultaneously mechanical stability, anti-short circuit capability also should be more reliable.The safety and stability of transformer is mainly manifested in the manufacture process control of coil, requires that high and low pressure coil electromagnetism balances, axial turn-to-turn closely, be evenly distributed.Therefore require coil-winding process, radial direction will roll tightly, axial close-packed arrays.Coil-winding process is installed on actinobacillus device by the draw drum being wound with enamelled wire, the iron core of enamelled wire to be spooled is arranged on tensioning apparatus, tensioning apparatus rotates to be wound around enamelled wire, and the hand-held enamelled wire of workman adjusts winding position to ensure tight to turn-to-turn of coil axes.
Although existing pay off rack can meet the unwrapping wire requirement of enamelled wire to a certain extent, but it still also exists following technical problem in actual use procedure, due to the shaft hole diameter size disunity of different draw drums, and the roller bearing diameter of actinobacillus device is unified, although the axis hole two ends of draw drum by fastening nuts on roller bearing, but when the axis hole of draw drum is greater than roller bearing diameter, draw drum is meeting and roller bearing generation relative motion under the tearing of enamelled wire, thus cause draw drum to be beated around roller bearing, workman is caused to be difficult to coiling enamelled wire accurately on the one hand, the tensioning Chengdu of enamelled wire is caused constantly to change on the other hand, thus affect the quality of coiling.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, can clamp draw drum and increase the fixture with draw drum contact-making surface.
Draw drum fixture in this programme, include the roller bearing passed for draw drum, roller bearing is fixed on support, described roller bearing is also provided with one with the sleeve of roller bearing threaded engagement, described sleeve is embedded in the axis hole of draw drum, the rubber stopper of a taper is provided with between sleeve and axis hole, described sleeve is through the central shaft of rubber stopper, and be provided with the first bulge loop withstanding on rubber stopper tip, the extruding nut that the other end of sleeve is provided with external screw thread and coordinates with external screw thread, is provided with metallic gasket between bottom described extruding nut and rubber stopper.
The draw drum fixture of this programme is adopted to have following advantage: due to sleeve and roller bearing threaded engagement, and sleeve is provided with rubber stopper, the tip of rubber stopper is extruded by the first bulge loop, the bottom of rubber stopper is extruded by metallic gasket and extruding nut, overall structure is fairly simple, first the axis hole of draw drum is set on roller bearing during use, then be connected with roller bearing by sleeve, the axis hole of the rubber stopper extruding draw drum on sleeve, then rotary squeezing nut is continued, make rubber stopper dilatancy under the stop of the first bulge loop, thus increase the contact area with draw drum axis hole, increase contact friction force, thus both clamped draw drum and have and can not cause damage to draw drum.
Preferably, the sidewall of described extruding nut is provided with the first throw rod, and it is more convenient and strength-saving that such arranging can make to extrude pulling of nut, avoids being equipped with extra spanner.
Preferably, described sleeve is provided with the second bulge loop preventing extruding nut from coming off, the sidewall of the second bulge loop is provided with the second throw rod, arranging like this can make when tightening or loosening extruding nut, extruding nut can not fall down, in addition, arranging of the second throw rod can allow the dismounting of sleeve more convenient, without the need to being equipped with extra spanner.
Preferably, the sidewall of described rubber stopper is provided with interconnective extruding bulge loop, and such arranging can make rubber stopper more easy in the process of crimp, and the contact area of extruding bulge loop and draw drum axis hole is larger.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment draw drum fixture.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises, roller bearing 1, sleeve 2, rubber stopper 3, the first bulge loop 4, extruding nut 5, second bulge loop 6, second throw rod 7, first throw rod 8, metallic gasket 9.
The draw drum fixture of embodiment is as shown in Figure 1: include the roller bearing 1 passed for draw drum, the outer surface of roller bearing 1 is provided with screw thread, roller bearing 1 is fixed on support, roller bearing 1 is also provided with one with the sleeve 2 of roller bearing 1 threaded engagement, sleeve 2 is metal structure, sleeve 2 is embedded in the axis hole of draw drum, the rubber stopper 3 of a taper is provided with between sleeve 2 and axis hole, the sidewall of rubber stopper 3 is provided with interconnective extruding bulge loop, rubber stopper can be made so more easy in the process of crimp, distortion contact area that is rear and draw drum axis hole is larger, sleeve 2 is through the central shaft of rubber stopper 3, and the first bulge loop 4 that withstands on rubber stopper 3 tip is set in end, first bulge loop 4 can replace with the nut of a welding or double nut, the extruding nut 5 that the other end of sleeve 2 is provided with external screw thread and coordinates with external screw thread, this one end of sleeve 2 also should arrange the second bulge loop 6 preventing extruding nut 5 from coming off, second bulge loop 6 also can adopt a nut be welded on sleeve 2 to replace, the sidewall of the second bulge loop 6 is provided with the second throw rod 7, to make when tightening or loosening extruding nut 5, extruding nut 5 can not fall down, arranging of second throw rod 7 can allow the dismounting of sleeve 2 more convenient, the sidewall of extruding nut 5 is provided with the first throw rod 8, more convenient and strength-saving to make extruding pulling of nut 5, in addition also metallic gasket 9 should be mounted with between extruding bottom nut 5 and rubber stopper 3, rubber stopper 3 is destroyed to avoid directly extruding nut 5.
The draw drum fixture of this programme is work like this: be first set on roller bearing 1 by the axis hole of draw drum, then be connected with roller bearing 1 by sleeve 2, rubber stopper 3 on sleeve 2 is dilatancy under the extruding extruding nut 5 and the first bulge loop 4, thus increase and contact with the extruding of draw drum axis hole, thus increase contact friction force, avoid draw drum and roller bearing 1 to shake or mutually slide.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection range of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection range that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
