Abstract
The utility model discloses an auxiliary fixture for brazing of a multi-flow-channel nozzle. The auxiliary fixture for the brazing of the multi-flow-channel nozzle comprises a fixture base (8), a fixture pressing plate (10), a fixture compression nut (11) and a fixture compression bolt (13). The lower portion of the fixture compression bolt (13) is fixedly arranged on the fixture base (8). The fixture pressing plate (10) and the fixture compression nut (11) are sequentially sleeved on the upper portion of the fixture compression bolt (13) from inside to outside. An end cover (2) which is used as a welded piece and a vortex machine (4) are arranged between the fixture base (8) and the fixture pressing plate (10) in a coaxial mode according to an assembly relationship which is that end surfaces are contacted in a matched mode, and the axial direction of the end cover (2) and the vortex machine (4) is parallel to the axial direction of the fixture compression bolt (13). The auxiliary fixture for the brazing of the multi-flow-channel nozzle is simple in structure, convenient to use and operate, and good in technical effect.
Description
Technical field
The utility model relates to soldering with auxiliary clamp structural design and applied technical field, and spout soldering auxiliary clamp in a kind of multithread road is provided especially.
Background technology
In the prior art, multithread road spout is the internal layer spout of the large-scale nozzle of combustion machine, is made up of vortice that has 12 wheel blades and end cap, and the wheel blade of vortice adopts soldering to be connected with end cap by designing requirement.The original method for welding of this spout be single part by the design drawing dimensioned, do not consider the change direction of joint clearance of brazing, gap; Measure the size of end cap and vortice bottom when vortice and end cap combination assembling with height gauge, after being of the required size, position with argon arc welding; Be coated with an amount of paste solder at the place to be welded of assembly wheel blade and end cap periphery before the soldering, carry out vacuum brazing at last.
People urgently wish to obtain a kind of good auxiliary clamp of technique effect that can use in multithread road spout brazing process, so that guarantee welding effect.
The utility model content
Order of the present utility model provides the good multithread road spout soldering auxiliary clamp of a kind of technique effect.
A kind of multithread road spout soldering auxiliary clamp, the clamping and positioning operation of welded part multithread road spout being carried out assist in the process of brazing operation; Being constructed as follows of welded part multithread road spout: end cap 2, whirlpool device 4, wherein: end cap 2 is arranged in whirlpool device 4 tops and the two is in contact with one another in coaxial mode; It is characterized in that: described multithread road spout soldering being constructed as follows: clamp base 8, anchor clamps pressing plate 10, anchor clamps clamp nut 11, anchor clamps hold-down bolt 13 with auxiliary clamp; Wherein:
The bottom fixed and arranged of anchor clamps hold-down bolt 13 is on clamp base 8, and anchor clamps pressing plate 10, anchor clamps clamp nut 11 are set in the top of hold-down bolt 13 successively from inside to outside; Cooperate the assembly relation of contact to be arranged between clamp base 8 and the anchor clamps pressing plate 10 as the end cap 2 of welded part and whirlpool device 4 according to coaxial and axial end, and its two axially and the axially parallel of anchor clamps hold-down bolt 13.
Described anchor clamps pressing plate 10 specifically is three pressing plates of " Y " font structure of five equilibrium along the circumferential direction, and it is provided with three pressure heads, is reserved with the gap of being convenient to welding operation between adjacent two pressure heads.
Multithread described in the utility model road spout soldering is simple in structure with auxiliary clamp, uses easy to operately, and technique effect is good.
