Embodiment Construction
[0025] See figure 1 — Figure 4 , the invention is a fixture for welding and positioning micro-diameter thin-walled tubes of heat exchangers. It mainly includes movable fixture 1, partition plate 2, and fixed fixture 3 parts. The positional relationship between them is: the partition plate 2 is inserted into the transverse groove of the movable fixture 1, and the semicircular holes at both ends are paired and coupled; then the movable fixture 1 is installed on the section of the fixed fixture 3 and fixed by upper and lower screws.
[0026] When the fixture is working, firstly, the second row of micro-diameter thin-walled tubes are passed through a series of circular holes in the middle of the partition plate 2, and then the first row of micro-diameter thin-walled tubes are placed in a series of semicircular holes in the fixing fixture 3, Then let the partition plate 2 cooperate with the fixing fixture 3, so that a series of semicircular holes of the parts are coupled and pai...
