Description
Technical field
The utility model belongs to high voltage electrical apparatus technical field, is specifically related to a kind of high-pressure composite sleeve and machining tool thereof.
Background technology
In high voltage electrical apparatus technical field, high voltage source is passed through wall by high-voltage wall bushing exactly, guides outdoor into or guide outdoor into by indoor by indoor, or passes through the device that shell wall carries out high voltage source guiding inside and outside high-voltage switch gear or transformer.
Fig. 1 to Fig. 3 shows a kind of traditional high-voltage wall bushing, and wherein Fig. 1 is a kind of perspective view of conventional high-tension wall bushing; To be high-voltage wall bushing shown in Fig. 1 increase a kind of perspective view after climbing insulating barrier removing to Fig. 2; Fig. 3 removes the decomposing schematic representation increasing the high-voltage wall bushing after climbing insulating barrier shown in Fig. 2.See Fig. 1 to Fig. 3, traditional wall bushing comprises conducting rod (1), be around in the inner insulating layer (2) at conducting rod (1) middle part, be arranged on the metal adpting flange (3) on inner insulating layer (2) outer wall and be set in that inner insulating layer (2) is upper and external insulation layer (4) is climbed in the increasing being positioned at described adpting flange (3) two ends, and described increasing is climbed external insulation layer (4) and is provided with increasing and climbs full skirt (42) and ring (43) is climbed in increasing.Traditional high-voltage wall bushing is in order to be fixed on inner insulating layer outer wall by metal adpting flange, need on inner insulating layer outer wall, mill out external screw thread (2-1), also internal thread groove (3-1) to be set on metal adpting flange inwall, then being spirally connected by metal adpting flange is fixed on inner insulating layer, then at the junction coated with conductive glue of inner insulating layer and metal adpting flange.This conventional high-tension sleeve pipe has following shortcoming: after (1) mills out screw thread on inner insulating layer outer wall, destroy the mechanical structure of its outer wall, reduce its mechanical strength and insulation property, and owing to being provided with rough thread groove, as easy as rolling off a log generation corona also causes a stroke sudden strain of a muscle electric discharge, damages bushing.(2) because needs mill out screw thread on inner insulating layer outer wall, this operation needs the groove first milling away nearly half length on inner insulating layer outer wall, and then external screw thread is milled out on remaining inner insulating layer outer wall, in this operation, need the layer milled away compared with weight, cause serious waste, this operation wastes time and energy simultaneously, and machining accuracy and difficulty higher, thus improve manufacturing cost.
And also have another structure of patent disclosure at present, the patent No. is: the utility model patent of 201010005902.6 discloses a kind of wall bushing, be arrange special gum box on the inwall of flange, carry out gluing after putting, glue top needs certain hour admittedly, and can not any displacement be carried out, in gel process, flange is easily subjected to displacement, the program trouble that this mode is processed, long processing time, and locate be inaccurate when connection.
Utility model content
The purpose of this utility model is, provides that a kind of cost is low, process time is short, the high-pressure composite sleeve of accurate positioning and machining tool thereof.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-pressure composite sleeve, comprise inner insulating layer, flange, flange inner wall is provided with draw-in groove, and draw-in groove is absorbed in the outer wall of inner insulating layer.
This is arranged on inner insulating layer and does not arrange any processing or extra auxiliary bindiny mechanism, do not change, just utilize the draw-in groove of flange, be absorbed in inner insulating layer outer wall, time is very short, and cost is very low, do not need two road processing or auxiliary materials, greatly save money, manpower, time cost, this physical connection structure can better ensure the performance of original parts, and meet the degree of fixation of very high strength simultaneously, anti-pressure ability also improves greatly, the process being connected to transport and storage with glue all can be subject to temperature, humidity, the impact of the various factorss such as the intensity of pressure, structure of the present utility model does not then have such problem.
Of the present utility modelly to be set to further: described draw-in groove is one or more in thread groove, salient point, groove.
This arranges the form listing several draw-in groove, but the object of draw-in groove is absorbed in the outer wall of inner insulating layer, therefore various projection or depression draw-in groove all right, various shape can meet utility model object of the present utility model, have more than and be limited to this one or more that enumerate, and various combination draw-in groove are set.
Of the present utility modelly to be set to further: a kind of geometrical clamp, comprise base, pressing mold, base is provided with and is provided with first indent with flange adaptation with second indent of flange adaptation, pressing mold, and first indent is corresponding with second indent, form one with the clip of flange adaptation.
This arrange in geometrical clamp utilize indent on base and pressing mold to process flange, upper-lower compacting can make flange generation deformation, pressure is utilized to be pressed in the outer wall of inner insulating layer by draw-in groove, the structure of this geometrical clamp is simple, cost is low, and location is also accurate, the time of processing is very short, and the Production Time of instrument is also very short.
Of the present utility modelly to be set to further: respectively establish three locating convex blocks in the both sides of base, to form positioning seat in Chinese character pin-shaped arrangement, the side of pressing mold and positioning seat adaptation, be stuck in positioning seat.
This is provided with the positioning seat of a Chinese character pin-shaped arrangement, so when base and pressing mold compress simultaneously, location is just very accurate, this location structure, not only accurate positioning, and make simple, with the simplest structure, complete the purpose of this utility model, reduce cost, and further increase the accuracy of location.
