Abstract
The utility model discloses a kind of for plasma electrode soldering fixture, comprise fixture cover and pad, fixture overlaps cylindrically hollow structure, the bottom barrel of fixture cover offers multiple arcuate recess, forms teeth portion between adjacent arcuate groove; Gasket surface arranges a ring annular groove, and annular groove and described fixture overlap external diameter and match, the groove clamping on the fixture cover teeth portion of bottom and pad.This fixture ensure electrode body substantially vertically place, thus ensure solder and electrode body coaxial.And fixture is single main body, structure is simple, and brazed portions is exposed in a vacuum furnace as far as possible, thus can fully be heated, and avoids heat radiation to be blocked and causes fusing insufficient.Every one deck gripper shoe can arrange multiple fixture, enhance productivity as much as possible, be applicable to mass production.
Description
Technical field
The utility model relates to field of fixtures, particularly relates to a kind of plasma electrode soldering fixture.
Background technology
Plasma cutting electrode mainly adopts the connection completed in two ways between electrode body and hafnium particle, i.e. interference press-fit and braze welding type on the market now.During interference press-fit connects, the size of the magnitude of interference is not easily controlled, and the standard that magnitude of interference size is imperfect yet calculates.Braze welding type plasma cutting process technology is with regard to effect aspect close to laser cutting, but cost is well below laser cutting, makes braze welding type plasma cutting technique obtain abundant development in each enterprise.And fixture is absolutely necessary when plasma electrode manufactures instrument, current braze welding type plasma cutting electrode needs special positioning fixture to locate joint clearance of brazing, and complex operation, plasma cutting electrode assembling unit structure is complicated.
A kind of fixture is disclosed in patent document CN102430827A, this fixture is made up of upper plate, lower plate and four support bars, and upper plate is provided with fixing hole and several locating holes of 4 fixed support bars, the upper surface of described lower plate is plane, place a plasma cutting electrode sub-assembly assembled in each locating hole, electrode assembly is just being seated in the fixture of bottom for horizontal plane and is carrying out soldering.There is following shortcoming in this fixture and method: 1) because electrode assembly is just being put into vacuum drying oven, this mode hafnium filament upper end must increase briquetting, to help hafnium filament pressure fully to weld with copper sheathing seat by external force, briquetting and fixture upper gap too little, causing after expanded by heating and deadly to lose efficacy, too large briquetting is easily crooked to be made hafnium filament eccentric and makes product failure; 2) this clamp structure upper and lower plates can stop the heating efficiency (block radiation heat) of vacuum drying oven, and the heat time, short then solder wire was non-fusible, or melted insufficient, easily formed cavity in joint; Time length can cause brazing filler metal erosion, generates more frangible compounds etc. in joint, even occurs crackle, affects the performance of joint, also wastes electricity simultaneously, strengthens production cost; 3) due to the method fixture and additional briquette structure complexity, cannot mass production.Seem extremely be necessary so design a kind of special fixture.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of plasma electrode soldering fixture, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
Plasma electrode soldering fixture, comprise fixture cover and pad, described fixture overlaps cylindrically hollow structure, and the internal diameter of fixture cover and the external diameter of electrode body match, the bottom barrel of described fixture cover offers multiple arcuate recess, between adjacent arcuate groove, forms teeth portion; Described gasket surface arranges a ring annular groove, and annular groove and described fixture overlap external diameter and match, the groove clamping on the fixture cover teeth portion of bottom and pad.
Preferably, described pad is ceramic gasket.
During welding, first by electrode body soldering hole upward, solder and hafnium particle are loaded in the soldering hole of electrode body successively from bottom to top, the electrode assembly assembled is inverted in this fixture, solder nose end is near pad, fixture cover fixed electrode main body, then by fixture horizontal positioned on the supporting plate, put into vacuum drying oven and carry out soldering.This fixture ensure electrode body substantially vertically place, thus ensure solder and electrode body coaxial.And fixture is single main body, structure is simple, and brazed portions is exposed in a vacuum furnace as far as possible, thus can fully be heated, and avoids heat radiation to be blocked and causes fusing insufficient.Every one deck gripper shoe can arrange multiple fixture, enhance productivity as much as possible, be applicable to mass production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pad;
Fig. 3 is the side view of Fig. 2;
In figure: 1 is fixture cover, 2 is pad, and 3 is arcuate recess, and 4 is teeth portion, and 5 is groove.
Detailed description of the invention
A kind of plasma electrode soldering fixture as Figure 1-3, comprise fixture cover 1 and pad 2, described fixture cover 1 cylindrically hollow structure, the described fixture cover internal diameter of 1 and the external diameter of electrode body match, the bottom barrel of described fixture cover 1 offers multiple arcuate recess 3, between adjacent arcuate groove 3, forms teeth portion 4; Described pad 2 surface arranges a ring annular groove 5, and annular groove 5 and described fixture overlap 1 external diameter and match, and fixture overlaps the teeth portion 4 of 1 bottom and groove 5 clamping on pad 2.Described pad 2 is ceramic gasket.
The utility model structure is simple, during welding, first by electrode body soldering hole upward, solder and hafnium particle are loaded in the soldering hole of electrode body successively from bottom to top, be inverted into by the electrode assembly assembled in this fixture, solder nose end is near pad, and fixture overlaps fixed electrode main body, again by fixture horizontal positioned on the supporting plate, put into vacuum drying oven and carry out soldering.This fixture ensure electrode body substantially vertically place, thus ensure solder and electrode body coaxial.And fixture is single main body, and brazed portions is exposed in a vacuum furnace as far as possible, thus can fully be heated, avoid heat radiation to be blocked and cause fusing insufficient.Every one deck gripper shoe can arrange multiple fixture, enhance productivity as much as possible, be applicable to mass production.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model, every according in technical spirit of the present utility model to any simple modification, equivalent variations that above embodiment is done, all fall within protection domain of the present utility model.
