Description
Technical field
The utility model relates to tube plate structure spare vacuum electron beam to braze anchor clamps that are used for vacuum electron beam to braze.
Background technology
Vacuum electron beam to braze is one of special processing technology of getting up of development in recent years, it is the novel solder technology of a kind of integrated electronics Shu Jiagong and vacuum brazing advantage, compare with vacuum brazing, electron beam to braze has the energy density height, but local heat helps guaranteeing the advantage of radiating tube intensity and part combination property.Part for this tube plate structure of radiator adopts electron beam to braze more, during its welding, no special fixture only depends on flat support part bottom, the tube plate structure that adopts this kind mode to weld, because treating faying face does not have the temperature protection measure, occur part easily and be heated the face cracking; Metallic vapour pollutes pipe, influences the mechanical performance of part, and distortion appears in part, connects precision and can not get guaranteeing, has a strong impact on the quality of electron beam to braze.
Summary of the invention: the purpose of this utility model provide a kind of when vacuum electron beam to braze tube plate structure spare the uniform vacuum electron beam to braze anchor clamps in heating surface temperature field.Technical solution of the present utility model is, anchor clamps are made up of chassis 1, shielding cylinder 2 and insulation hoop 3, have the locating slot 4 of fixed mask tube 2 on the chassis 1, and the centre on chassis is a positioning boss 5, the outside of locating slot 4 is three screwed holes 6 of distribution evenly, both sides fixed armrest 7; Shielding cylinder 2 is located in the locating slot 4, and the top of shielding cylinder 2 is provided with the insulation hoop of being made up of asbestos and stainless steel material 3, and insulation hoop 3 is the semicircle of two band ears, drives locating hole 8 on the ear.The utility model is based on the universal electronic beam device, binding isotherm research and technology test result, successfully solved the core technology problem that electron beam to braze faces-heating surface temperature field homogeneity question, guaranteed the repeatability of product quality, given full play to the sharpest edges of electron beam to braze technology, this clamp structure is simple, is easy to processing, do not need complicated transmission device, can realize the condition of technological requirement.These anchor clamps have played protective effect to the position of workpiece non brazing in the assembling, location that realize workpiece.The utility model can be according to the size and the electron beam scanning scope of rotary table in the vacuum chamber, determine the size of anchor clamps, the size and the shape of the shielding cylinder of anchor clamps and insulation hoop can change according to the size and the shape of radiator, and the shape on chassis and size also can change arbitrarily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation on the utility model chassis;
Fig. 3 is the top view of Fig. 2;
Fig. 4 is the utility model insulation hoop schematic diagram;
Fig. 5 is the utility model shielding cylinder schematic diagram.
The specific embodiment
Anchor clamps are made up of chassis 1, shielding cylinder 2 and insulation hoop 3 three parts.
Among Fig. 1, The One On The Chassis locating slot 4 is fixed together chassis 1 and shielding cylinder 2 and keeps concentric, will be incubated with bolt 10 and bind round 3 and be connected with welded part 9 corresponding sites, is being connected of welded part 9 and chassis 1 that positioning boss 5 by 1 middle part, chassis guarantees.Even three supporting seat holes 6 that distribute on the circumference on chassis 1, and by carrying bolt 11 supports.During work anchor clamps are fixed on the rotary table of vacuum chamber, workbench drives the anchor clamps rotation in rotating process.
Among Fig. 2, chassis 1 material is stainless steel 1Cr18Ni9Ti, drives locating slot 4 on the chassis 1, and has processed positioning boss 5, and locating slot 4 is for fixed mask tube 2, and positioning boss 5 is by the weldering part for fixing.1 both sides, chassis are fixed with handrail 7, are convenient to the carrying of whole anchor clamps and part.3 each screwed hole 6 are arranged at 1 bottom, chassis, can be by the level of bolt 11 alignment jigs.Support, the positioning action to part and other anchor clamps played on chassis 1 in whole clamper component.
Among Fig. 4, insulation hoop 3 materials are stainless steel 1Cr18Ni9Ti, between insulation hoop 3 and the part 9 certain clearance are arranged, and fill asbestos at gap location, to reach the effect of insulation.3 pairs of braze surface of insulation hoop have played insulation effect, prevent scattering and disappearing of heat, reduce the loss of energy.
Among Fig. 5, shielding cylinder 2 materials are stainless steel 1Cr18Ni9Ti, in the process of soldering, shielding cylinder 2 are installed in the outside of welded part 9, prevent from that metallic vapour is smoked to be coated on the welded part 9.
With the soldering radiator is example, according to the size and the electron beam scanning scope of rotary table in the vacuum chamber, determines the size of disk; radiator need be fixed on the chassis; and with shielding cylinder and insulation hoop the non brazing position is protected, then, it is fixed on the rotary table.By the rotation of workbench, drive the anchor clamps that link to each other with the workbench main shaft and rotate.The size and the shape of shielding cylinder and insulation hoop can change according to the size and the shape of radiator.The shape on chassis and size can change arbitrarily.Compare with vacuum brazing, electron beam to braze belongs to local heat, can guarantee the intensity of radiating tube and the combination property of part, and soldering and temperature retention time weak point, can obviously improve working (machining) efficiency, reduces welding cost.
