Detailed Description

Referring to fig. 1-4, an embodiment of the present invention provides an apparatus for carding and trimming heat exchanger lodging fins, comprising a handheld end 1, a plurality of comb teeth 5, a fixed support 2, an unequal-spacing adjusting shaft 3 and a fastening limiting device. The fastening limiting device comprises a supporting bracket 7 penetrating through the fixing bracket 2, a fastening wheel 6 (the fastening wheel is clamped on the supporting bracket 7 in a clamping mode, the fastening wheel 6 is fixed on the fixing bracket 2 through the flexibility and friction force of silicon rubber, the fastening wheel 6 can rotate around the supporting bracket 7 after being clamped) and a fin limiting bracket 4, and the fin limiting bracket 4 is in threaded connection with the fastening wheel 6. The unequal-spacing adjusting shaft 3 is connected with the fixed support 2 through a shaft. The top end of the fixed bracket 2 is inserted in the handheld end 1. Wherein, broach 5 adopts ABS plastics material. The unequal-spacing adjusting shaft 3 is made of ABS plastic. The fastening wheel 6 is made of silicon rubber.

A plurality of broach 5 is installed on unequal interval adjusting shaft 3, specifically as follows: wherein, the comb teeth 5 are provided with tenons, the end parts are conical and the surfaces are smooth; the surface of the unequal-interval adjusting shaft 3 is provided with dovetail grooves with equal interval change, tenons of the comb teeth 5 are inserted into the dovetail grooves, and the comb teeth 5 can slide in the dovetail grooves. The space between the comb teeth 5 is uniformly increased or reduced by rotating the space adjusting disk at the side of the unequal space adjusting shaft 3. The method comprises the following steps: when the fin limiting support 4 is opened, the comb teeth 5 can slide along the dovetail groove on the unequal-interval adjusting shaft 3. The pitch of the comb tooth grooves of the unequal pitch adjusting shaft is different in each angular direction, as shown in fig. 5, when the unequal pitch adjusting shaft 3 is rotated, the pitch of the comb tooth dovetail grooves is gradually increased or decreased, and the purpose of comb tooth change is achieved.

When the comb teeth 5 need to be fixed, the fin limiting support 4 can be pressed downwards (when the fin limiting support is pressed downwards, the fastening wheel 6 connected with the fin limiting support 4 rotates), so that the fin limiting support 4 is pressed on the comb teeth 5 to play a role in fixing the comb teeth 5. When the distance between the comb teeth 5 needs to be adjusted, the fin limiting support 4 can be lifted (when the fin limiting support 4 is lifted, the fastening wheel 6 connected with the limiting support 4 rotates), so that the fin limiting support 4 is separated from the comb teeth 5, and the distance between the comb teeth 5 can be adjusted along with the rotation of the unequal-distance adjusting shaft 3. Fig. 2 and fig. 3 are schematic diagrams of the comb teeth 5 in different pitch states.

When the comb teeth fixing device is used, the unequal-interval adjusting shafts 3 are rotated to the intervals of the required comb teeth 5 according to the intervals of the fins of the radiator, and the fin limiting supports 4 are pressed down to ensure that the comb teeth 5 are completely fixed. Inserting the comb teeth 5 into the fin gap, and checking whether the fin gap before expansion joint of the tube and the fin meets the design requirement; after the tube and the fins are expanded, the tube and the fins are inserted into the gaps of the fins through the comb teeth 5 and are combed along the direction of the fins, and the fallen fins are subjected to straightening and shaping; greasy dirt sundries among the fins can be cleaned by replacing the long comb teeth 5, and the operation efficiency is high. Meanwhile, in order to meet the use requirement of large nonstandard radiator equipment, the equipment is in a handheld operation mode.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
