The working process and principle of the invention are as follows:
firstly, the press fitting joint 43 is located at an initial position, the feeding seat 65 is located below the gap 9, the air cylinder 64 extends out, the feeding seat 65 moves upwards to the front end of the press fitting joint 43, then the press fitting joint 43 is driven by the hydraulic cylinder to move forwards for a short distance, the press fitting joint 43 is inserted into a heat exchange tube, namely, the position shown in fig. 3, the heat exchange tube is positioned by the press fitting joint 43 at the moment (the cross section of the press fitting joint 43 is in a T shape) and cannot fall off, then the air cylinder 64 retracts, the hydraulic rod 42 is started and drives the press fitting joint 43 to drive the heat exchange tube to continue moving forwards until the heat exchange tube is pressed into a through hole in a tube plate, the driving gear wheel drives the second gear wheel 73 to rotate in the process, and the expansion mechanism 5 and the feeding mechanism 6 work in the process as follows:
and (5) an expansion mechanism: the second gear 73 drives the first driven rack 72 to move towards the direction opposite to the moving direction of the heat exchange tube until the first driven rack reaches the limit position, namely the expansion mechanism 5 is positioned at one end far away from the fixed tool 1;
a feeding mechanism 6: the second gear 73 drives the third gear 81 to rotate, the third gear 81 drives the second driven gear 73 to move, the moving direction of the second driven rack 82 is perpendicular to the moving direction of the heat exchange tube, and the second driven rack 82 drives the sliding block 84 to move to a material taking station through the connecting piece 83 to take materials. Considering that the driven rack gear two 82 still displaces when the press fitting joint 43 is inserted into the heat exchange tube, a moving groove 621 with a length larger than that of the sliding block 84 is arranged at the bottom of the sliding seat three 62, in the process from the time of inserting the press fitting joint 43 into the heat exchange tube to the time of inserting the press fitting joint into the heat exchange tube completely, the sliding block 84 moves from the left end to the right end of the moving groove 621, the sliding seat three 62 does not move yet, the air cylinder 64 retracts to move the feeding seat 65 downwards, then the press fitting joint 43 moves forwards continuously, and the sliding block 84 can drive the sliding seat three 62 and the feeding seat 65 to move towards the material taking station.
Secondly, after the press fitting is completed, the hydraulic rod 42 retracts until the initial position is reached, and the working processes of the expansion mechanism 5 and the feeding mechanism 6 in the process are as follows:
and (5) an expansion mechanism: the second gear 73 drives the first driven rack 72 to move towards the opposite direction of the moving direction of the heat exchange tube, namely, in the process of moving towards the tube plate, the sliding sleeve 562 is firstly contacted with the tube plate, along with the continuous forward movement of the expansion head 55, the sliding sleeve 562 is pressed on the end surface of the tube plate until reaching the limit position, the expansion head 55 at the moment is positioned in the heat exchange tube, and the driving motor 54 is started to expand and connect the heat exchange tube;
a feeding mechanism 6: the second gear 73 drives the third gear 81 to rotate, the third gear 81 drives the second driven gear 73 to move, the moving direction of the second driven rack 82 is perpendicular to the moving direction of the heat exchange tube, the second driven rack 82 drives the sliding block 84 to move to the press-fitting station through the connecting piece 83, and the sliding block 84 is located at the left end of the moving groove 621 at the moment. Then, the cylinder 64 is extended, and the heat exchange pipe is fed to the front end of the press fitting 43 by the feed shoe 65.
The steps are repeated, and the processes of press fitting, expanded joint and feeding of the heat exchange tube can be continuously completed.
In this embodiment, the processing position of the expansion mechanism 5 is located at the third rear of the press-fitting position, and in the initial stage, that is, when no heat exchange tube can be expanded, the expansion mechanism 5 is in an empty state, and the operation is not affected, and since the outer diameter of the expansion head 55 is smaller than the diameter of the through hole in the tube plate, the through hole in the tube plate is not affected. Further, since the discharge of the material into the feeding base 65 can be stopped after the press-fitting is completed, the press-fitting mechanism 4 continues its operation, but the press-fitting result is not generated.
In the embodiment, only the assembling equipment of the heat exchange tubes on the upper and lower rings of the tube plate is shown, and for the inner ring part, the height of the press-fitting mechanism 4 and the specific position of the expansion mechanism 5 can be changed, so that the assembling of the inner ring heat exchange tubes can be realized.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
