Description
Technical field
The present invention relates to a kind of burnishing device that polishing is carried out on power capacitor oil filler point seals at soldering surface.
Background technology
Power capacitor is a kind of electrical equipment that is widely used in power system.For capacitor, the problem of oil filler point seal closure seals at flatness becomes the key factor that influences the product appearance quality.Because what sealing surface adopted is the soldering sealing, the shell base material of capacitor is a stainless steel, though warded off tin in seals at before the welding; During welding, it is uneven that the scolding tin surface still can the edge occur, defectives such as list edge, scolding tin accumulation; Therefore, also need to carry out smooth processing after welding finishes, and the mode of carrying out smooth processing at present is to use and frustrates cutter and it is frustrated flat to weld; This method labour intensity is big, and efficient is low.
Summary of the invention
The technical problem that the present invention will solve is to the deficiency that exists in the prior art, and a kind of simple in structure, the burnishing device that is used for power capacitor oil filler point seals at that can effectively increase work efficiency and reduce labor intensity of operating staff is provided.
The burnishing device that is used for power capacitor oil filler point seals at of the present invention comprises splined shaft, is set in polishing blade, cutting force adjusting device and positioner on the splined shaft, and one can drive the power set that splined shaft rotates, wherein,
The two ends of said splined shaft are optical axis, and mid portion is followed successively by helicitic texture and spline structure from top to bottom;
Said polishing blade comprises the knife rest of bar shape and on knife rest, is several cutter heads of circumferential array; Described knife rest and cutter head are structure as a whole; The diameter of a circle that described several cutter heads surround is a bit larger tham the bore of power capacitor oil filler point seal closure; Offer the spline that matches with splined shaft upper spline structure on the knife rest, described polishing blade is set in the spline structure part of splined shaft;
Said cutting force adjusting device comprises the nut that is installed on the helicitic texture place of splined shaft on the spring that places on the knife rest, spring end cap, the spring end cap;
Said positioner is for to be installed on the locating piece on the optical axis of splined shaft bottom through bearing, and the profile of this locating piece bottom shape and power capacitor oil filler point seal closure is corresponding, and the top of said bearing and bottom above back-up ring respectively are spacing with following back-up ring.
In the technique scheme, described power set are generally selected electric hand drill for use, and the output shaft of this electric hand drill is connected with the optical axis on splined shaft top.The preferred rotating speed adjustable electric hand drill that adopts is realized low rate start, improves the stability of whole device.
In order spring to be positioned further improve the steadiness of whole device on the polishing blade knife rest, can on the surface on knife rest top, offer an annular groove, said spring bottom is placed in this annular groove.
The cutter head of said polishing blade is generally 2～5, and preferred 3, their equi-spaced apart arrangements in a circumferential direction.
Compared with prior art, the advantage of device according to the invention is:
1, drives the splined shaft rotation through power set; Splined shaft drives and is set in the structural polishing blade rotation of its upper spline; In the rotary course of polishing blade; The blade place of polishing blade cutter head promptly accomplishes polishes, wipes off the list edge on power capacitor oil filler point seals at soldering surface etc., and then accomplishes the smooth processing that weld is carried out.
2, to act on the cutting force on soldering surface be adjustable (length that changes spring through nut realizes) to polishing blade; Regulating the cutting force that the back polishing blade acts on soldering surface is exactly the elastic force of spring; Polishing blade does not damage capacitor case with regard to only processing is polished, wipeed off to the list edge on capacitor oil filler point seals at soldering surface etc. like this.
3, because whole smooth processing procedure drives by power set, operating personnel only need be close to the locating piece of burnishing device on the seal closure and get final product with the control direction, thereby greatly reduce the labour intensity of this operation, have also improved operating efficiency simultaneously.
4, through this device oil filler point sealing weld solder side is polished smooth processing, improved the capacitor presentation quality greatly.
