Abstract
The utility model relates to a spot-welding electrode for a honeycomb exchange component, which mainly solves the problem that a honeycomb cell cracks due to rigid contact of the conventional spot-welding electrode and the surface of a honeycomb. The spot-welding electrode is characterized in that a rubber block (2) is fixedly arranged at the top of the electrode (5) through a copper piece (1), the lower edge of the copper piece (1) is contacted with an outer wall of the electrode (5), and the copper piece (1) is fixedly arranged outside the electrode (5) through a fastening bolt (4). Compressing deformation of the electrode contacted with the honeycomb structure can be avoided due to the rigid contact of the spot-welding electrode and the surface of the honeycomb, and the honeycomb cell during spot welding of the honeycomb is prevented from cracking.
Description
Technical field
The utility model relates to aerospace field, and a kind of specifically aircraft engine low-pressure turbine honeycomb that the sector honeycomb changes repair work of obturaging that is used for is changed the part spot-wedling electrode.
Background technology
In the aircraft engine low-pressure turbine was obturaged the sector honeycomb, the nickel based metal honeycomb was changed the tack-weld of part and part base solid, was different from the spot welding that common metal thin-wall structure connects.Common metal structure spot welding requires the spot welding position to reach sufficiently high bonding strength, and needs to guarantee the tearing strength of spot welding bonding strength greater than the thin-wall metal matrix through tear strength test.And the tack-weld of nickel based metal honeycomb; Requirement is with the spot-wedling electrode thrust of trying one's best little and the little discharge current of trying one's best; Making the formation of slightly discharging between metal beehive and the part base solid temporary fixed; Eliminate the gap between honeycomb and the piece surface,, realize that the capillary of brazing solder is sprawled so that in the follow-up vacuum brazing process; Also require to act on the downforce of spot-wedling electrode simultaneously, must not cause honeycomb to change the areal deformation of part and the cracking of cellular unit lattice.And existing spot-wedling electrode may make honeycomb compress distortion owing to contact for rigidity with the honeycomb surface, causes cellular unit bridge cracking.
Summary of the invention
[0003], rigidity causes the deficiency of cellular unit lattice cracking for contacting in order to overcome existing spot-wedling electrode and honeycomb surface; The utility model provides a kind of honeycomb to change the part spot-wedling electrode; This spot-wedling electrode contacts for meat property with the honeycomb surface; That can avoid electrode pair honeycomb when contact compresses distortion, the cellular unit lattice cracking when preventing honeycomb spot welding.
The technical scheme of the utility model is: a kind of honeycomb is changed the part spot-wedling electrode, comprises electrode, and described top of electrodes is fixed with block rubber through copper sheet, and described copper sheet lower edge contacts with the electrode outer wall, and through fastening bolt copper sheet is fixed on the electrode outside.
The outside of described copper sheet and electrode contact site is provided with cushion block, and fastening bolt passes cushion block and electrode is pressed on the electrode outside with cushion block.
The utlity model has following beneficial effect: owing to take such scheme; Top of electrodes is fixed with block rubber through copper sheet, and by fastening bolt copper sheet is fixed on the electrode outer wall, during honeycomb spot welding; Copper sheet is realized the conducting function of electrode; Inner elastic caoutchouc can improve the applying with the honeycomb surface, increases contact area, improves honeycomb spot welding effect; The flexibility on simultaneity electrode and honeycomb surface contact, compresses distortion in the time of can avoiding the contact of electrode pair honeycomb, and the cellular unit lattice in the time of can also preventing honeycomb spot welding ftracture.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1-copper sheet among the figure, 2-block rubber, 3-cushion block, 4-fastening bolt, 5-electrode.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, a kind of honeycomb is changed the part spot-wedling electrode, comprises electrode 5, and in order to make copper sheet 1 fixation, the sidewall at electrode 5 middle parts is provided with groove.Described electrode 5 tops are fixed with block rubber 2 through copper sheet 1; Copper sheet 1 is pressed in block rubber 2 tops; Described copper sheet 1 lower edge contacts with electrode 5 outer walls, and the edge of copper sheet 1 is located in the groove on electrode 5 sidewalls, and through fastening bolt 4 copper sheet 1 is fixed on electrode 5 outsides.More reliable for copper sheet 1 is contacted with electrode 5, described copper sheet 1 can be provided with cushion block 3 with the outside of electrode 5 contacts site, and described cushion block 3 is two, and after fastening bolt 4 passed cushion block 3 and electrode 5, the nut of screwing was pressed on electrode 5 outsides with cushion block 3.Copper sheet 1 edge is fixed between cushion block 3 and the electrode 5, makes copper sheet 1 and electrode 5 fit tightr.
During honeycomb spot welding, copper sheet 1 is realized the conducting function of electrode 5, and the elastic block rubber 2 of inner core can improve the applying with the honeycomb surface, increases contact area, improves honeycomb spot welding effect; Simultaneously electrode is fitted with the flexibility on honeycomb surface, compresses distortion in the time of can avoiding the contact of electrode pair honeycomb, and the cellular unit lattice in the time of can also preventing honeycomb spot welding ftracture.
