Referring to fig. 12 and 13, after the heat dissipation pipes 1 and the heat dissipation bands 2 are placed, the pressing and positioning mechanism 8 is inserted into the supporting screw 7, and then the pressing and positioning mechanism 8 is rotated to arrange the excessively dislocated heat dissipation bands 2 and press the heat dissipation pipes 1 and the heat dissipation bands 2.
Then, the opening positioning piece 6 and the positioning frame 5 are detached from the bottom plate, the sealing heads 3 are inserted into the openings 31 of the heat dissipation belt 2 one by one, and the heat dissipation pipe 1 and the heat dissipation belt 2 which are in the process of being compressed are bundled by iron wires.
After the bundling is finished, the pressing and positioning mechanism 8 is detached;
and finally, taking down the bundled heat dissipation core body, and carrying out the welding process of the next working procedure.
In addition, it is preferable that the bottom plate 4 of the present invention is provided with a second groove 42 having a ring shape, and after the pressing and positioning mechanism 8 presses the radiating pipe 1 and the radiating band 2, the lower end of the arranging portion 845 of the tensioning member 848 enters into the second groove 42, which is beneficial: the interference between the tensioning part 848 and the upper end face of the base plate 4 when the pressing and positioning mechanism 8 is pressed can be avoided, so that the pressing effect is not good.
Meanwhile, the bottom plate 4 of the invention is provided with an iron wire through slot 43, and when the heat dissipation core body is bound, the iron wire passes through the bottom end of the heat dissipation core body through the iron wire through slot 43.
In summary, the invention provides a positioning tool for assembling a core body of a radiator, which comprises a bottom plate; the positioning frame is of a cylindrical frame structure and is detachably arranged on the bottom plate; the opening positioning pieces are symmetrically provided with two groups, and each opening positioning piece comprises an installation seat and a positioning plate with a positioning groove arranged therein; the positioning plate is longitudinally vertical to the mounting seat; the positioning plate is arranged at an angle of 30-75 degrees with one side edge of the mounting seat; the mounting seat is detachably mounted on the bottom plate; the supporting screw rod is movably arranged in the center of the bottom plate through an inserting structure; the supporting screw rod is provided with a first thread in a middle preset area; the pressing and positioning mechanism comprises a rotation driving assembly, a pressing assembly and a concentric positioning assembly; the concentric positioning assembly comprises a plurality of tensioning pieces annularly arranged below the pressing and positioning mechanism; under the rotation of the rotation driving component, the vertical movement of the pressing and positioning mechanism is realized, and meanwhile, the tensioning piece is driven to move outwards or inwards.
