Description

Air conditioner heat exchanger welding jig

Technical Field

The utility model relates to an air conditioner spare part technical field especially relates to an air conditioner heat exchanger welding jig.

Background

The heat exchanger mounting panel need with the heat exchange tube with the brazing welding together, in order to guarantee its welding quality, adopt a base, put mounting panel and heat exchange tube on the base, artifical iron wire with the mounting panel and heat exchange tube tie up send brazing furnace to brazing together, because in the stove in-process of brazing, receive the part that high temperature made brazed and produce the inflation, for this reason, the elasticity that requires the iron wire to tie up heat exchanger mounting panel and heat exchange tube will be suitable, it is not firm to weld when too loose, too tight then probably causes the damage because of thermal energy deformation, it is many to consume man-hour, low in production efficiency.

Disclosure of Invention

The utility model aims at solving the technical problem and providing an air conditioner heat exchanger welding jig.

In order to realize the technical purpose, reach foretell technical requirement, the utility model discloses the technical scheme who adopts is: the utility model provides an air conditioner heat exchanger welding jig, includes base, crosspiece, its characterized in that: the left end and the right end of the upper surface of the base are welded with bottom plates, and the middle part of the base is welded with a plurality of crosspieces; u-shaped groove plates are fastened on the front side and the rear side of the bottom plate through screws, a baffle shaft is arranged on each U-shaped groove plate, a spring, a pressing plate and a limiting pin are sequentially arranged on the baffle shaft in the U-shaped groove of each U-shaped groove plate from outside to inside, and the limiting pin is also arranged on the baffle shaft outside each U-shaped groove plate; and a transverse pin is arranged on the limit pin.

Preferably: the baffle is arranged on the end surface of the inner side of the baffle shaft.

Preferably: and a moving distance is arranged between the baffle on the baffle shaft and the U-shaped groove plate.

FIG. 1 is a schematic front view of the present invention;

fig. 2 is a schematic top view of the present invention;

FIG. 3 is an enlarged view of portion A of FIG. 1;

in the figure: 1. a base; 2. a crosspiece; 3, U-shaped groove plates; 4. a base plate; 5. a spring; 6. a spacing pin; 7. pressing a plate; 8. a transverse pin; 9. a blocking shaft; 10. and a baffle plate.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the figure: the utility model provides an air conditioner heat exchanger welding jig, includes base 1, crosspiece 2, its characterized in that: the left end and the right end of the upper surface of the base 1 are welded with bottom plates 4, and the middle part of the base 1 is welded with a plurality of crosspieces 2; the U-shaped groove plates 3 are fastened on the front side and the rear side of the bottom plate 4 through screws, the blocking shafts 9 are arranged on the U-shaped groove plates 3, springs 5, pressing plates 7 and limiting pins 6 are sequentially arranged on the blocking shafts 9 in U-shaped grooves of the U-shaped groove plates 3 from outside to inside, and the limiting pins 6 are also arranged on the blocking shafts 9 on the outer sides of the U-shaped groove plates 3; and the limiting pin 6 is provided with a transverse pin 8. The baffle 10 is arranged on the end surface of the inner side of the baffle shaft 9. And a moving distance is arranged between the upper baffle of the baffle shaft 9 and the U-shaped groove plate 3. The U-shaped groove plate 3 is provided with a long groove.

During specific implementation, a heat exchanger to be welded and a heat exchange tube are placed on a base, the heat exchange tube on the left side is just contacted with a baffle on the left side, at the moment, a spring is in an out-of-work state, or the heat exchange tube is not contacted with the baffle, but the gap is smaller than 1mm, otherwise, a heat exchanger mounting plate and the heat exchange tube are welded firmly; when the heat exchange tube is just contacted with the baffle or the gap is smaller than 1mm, the heat expansion during brazing is absorbed by the spring, and the parts cannot deform and damage. For heat exchangers with different specifications, a baffle shaft matched with the heat exchangers can be selected, the positions of two limiting pin holes on the baffle shaft are different, and the position of a baffle plate can be changed; or adjusting the position of the U-shaped groove plate.

The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
