Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger fin installation equipment, and particularly relates to a clamping device for heat exchanger fins. Background Art

[0002] Heat exchanger fins play a crucial role in finned heat exchangers. They increase the heat transfer surface area to improve the heat transfer efficiency of the heat exchanger.

[0003] During the installation of heat exchanger fins, a clamping device is required to successively move each heat exchanger fin to the corresponding mounting rack one by one. In order to enable the clamping device to pick up the heat exchanger fins more precisely, guiding holes are usually provided on the heat exchanger fins, and positioning studs corresponding to the guiding holes are usually provided on the clamping device.

[0004] However, the positioning studs usually need to penetrate through the heat exchanger fins through the guiding holes, and the positioning studs will extend out a relatively long length. When the position interval between adjacent heat exchanger fins on the mounting rack is short, the positioning studs are very likely to interfere with the previous heat exchanger fin, affecting the normal installation of the heat exchanger fins.

[0005] Therefore, further improvement is needed. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a clamping device for heat exchanger fins, which can adapt to the installation requirements of heat exchanger fins with a short installation spacing and improve the applicability of the device.

[0007] The purpose of the utility model is achieved as follows:

[0008] A clamping device for heat exchanger fins includes a guiding part corresponding to the guiding holes of the heat exchanger fins and a fin picking part capable of grasping the heat exchanger fins. The guiding part includes a first guiding column, and the first guiding column is connected with a guiding column driving device. The first guiding column can extend outwards or be received inwards through the guiding column driving device.

[0009] As a specific scheme, the end of the first guiding column capable of extending outwards is provided with a guiding inclined surface, and the radial width of the guiding inclined surface decreases along the extending direction of the first guiding column.

[0010] As a specific scheme, a second guiding column is sleeved outside the first guiding column. The first guiding column and the second guiding column are concentrically arranged and are slidably connected to each other.

[0011] As a specific scheme, a first limiting convex step is provided on the first guiding column, and a second limiting convex step corresponding to the first limiting convex step is provided on the second guiding column. When the first guiding column is received inwards relative to the second guiding column, the first limiting convex step abuts against the second limiting convex step.

[0012] As a specific solution, the first guiding column and the guiding column driving device are detachably connected to each other and fixed by a locking device.

[0013] As a specific solution, the sheet taking part is in the shape of a suction cup, and a negative pressure generating device is connected to one end of the sheet taking part facing away from the heat exchanger fins.

[0014] As a specific solution, the clamping device for the heat exchanger fins further includes a mounting main board. Each sheet taking part and two guiding parts form a sheet taking assembly, and a number of groups of sheet taking assemblies are distributed on the mounting main board.

[0015] As a specific solution, a number of mounting parts are provided on the mounting main board. A set of sheet taking assemblies is provided on each mounting part. Avoidance grooves are provided at positions on the mounting main board corresponding to adjacent mounting parts, and the lower side of the avoidance groove is in an open shape.

[0016] As a specific solution, the mounting main board is connected with a lifting mechanism, and the mounting main board can move back and forth vertically through the lifting mechanism.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The first guiding column can protrude outwards when the sheet taking part takes the heat exchanger fins, so as to improve the installation accuracy. The first guiding column can also be retracted inwards when installing the heat exchanger fins, avoiding interference between the first guiding column and adjacent heat exchanger fins, so that the clamping device can adapt to the installation requirements of heat exchanger fins with a short installation distance, and improve the applicability of the equipment.

[0024] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0025] See Figures 1 - 5, The clamping device for the heat exchanger fins includes a guiding part 2 corresponding to the guiding holes 11 of the heat exchanger fins 1 and a picking part 3 capable of grasping the heat exchanger fins 1. The guiding part 2 includes a first guiding column 22, and the first guiding column 22 is connected with a guiding column driving device 4. The first guiding column 22 can extend outwards or be retracted inwards through the guiding column driving device 4. When picking up the heat exchanger fins 1, the guiding part 2 will extend out and insert into the guiding holes 11 of the heat exchanger fins 1, and then the picking part 3 starts to work and fixes the heat exchanger fins 1.

[0026] The first guiding column 22 can extend outwards when the picking part 3 picks up the heat exchanger fins 1 to improve the installation accuracy. The first guiding column 22 can also be retracted inwards when installing the heat exchanger fins 1 to avoid interference between the first guiding column 22 and the adjacent heat exchanger fins 1, so that the clamping device can adapt to the installation requirements of heat exchanger fins 1 with a shorter installation spacing and improve the applicability of the device.

[0027] Furthermore, a guiding inclined surface 221 is provided at one end of the first guiding column 22 that can extend outwards. The radial width of the guiding inclined surface 221 decreases along the extending direction of the first guiding column 22. The first guiding column 22 can pass through the guiding holes 11 of the heat exchanger fins 1 more smoothly during the extending process, and at the same time, the position of the heat exchanger fins 1 can be finely adjusted by using the guiding inclined surface 221.

[0028] Furthermore, a second guiding column 21 is sleeved outside the first guiding column 22. The first guiding column 22 and the second guiding column 21 are concentrically arranged and slidably connected to each other. The second guiding column 21 can continue to play a role in limiting the heat exchanger fins 1 after the first guiding column 22 is retracted, and the positions of the first guiding column 22 and the second guiding column 21 are relatively overlapped, which can save the space position of the device.

[0029] Furthermore, a first limiting convex step 222 is provided on the first guiding column 22, and a second limiting convex step 211 corresponding to the first limiting convex step 222 is provided on the second guiding column 21. When the first guiding column 22 is retracted inwards relative to the second guiding column 21, the first limiting convex step 222 abuts against the second limiting convex step 211, improving the accuracy when the first guiding column 22 is retracted inwards.

[0030] Furthermore, the first guiding column 22 and the guiding column driving device 4 are detachably connected and fixed through a locking device 5, which is convenient for users to replace different first guiding columns 22 according to the actual situation. At the same time, the second guiding column 21 cooperating with the first guiding column 22 can also be replaced, so that the device can adapt to more different production needs and improve the adaptability of the device.

[0031] Furthermore, the picking part 3 is in the shape of a suction cup. A negative pressure generating device 6 is connected to the end of the picking part 3 facing away from the heat exchanger fins 1, so that the picking part 3 can easily take out and fix the heat exchanger fins 1.

[0032] Further, the clamping device for heat exchanger fins further includes a mounting main board 7. Each sheet-taking part 3 and two guiding parts 2 are combined to form a sheet-taking assembly. A number of groups of component-taking assemblies are distributed on the mounting main board 7, which can fix and position different positions on the heat exchanger fins 1, thereby further improving the stability and accuracy of installing the heat exchanger fins 1.

[0033] Further, a number of mounting parts 71 are provided on the mounting main board 7. A set of component-taking assemblies is provided on each mounting part 71. Avoidance grooves 72 are provided at the positions between adjacent mounting parts 71 on the mounting main board 7. The lower side of the avoidance grooves 72 is open. The bracket 9 for installing and fixing the heat exchanger fins 1 usually has a clamping structure 91 that protrudes upward for clamping the heat exchanger fins 1. The avoidance grooves 72 can enable the mounting main board 7 to pass through the clamping structure 91 smoothly, so that the heat exchanger fins 1 can be installed and fixed at the bottom of the bracket 9, thereby improving the stability of installing the heat exchanger fins 1.

[0034] Further, the mounting main board 7 is connected with a lifting mechanism 8. The mounting main board 7 can move back and forth vertically through the lifting mechanism 8, so that the mounting main board 7 can complete the effect of installing the heat exchanger fins 1 and resetting.

[0035] The working process of the present utility model is as follows:

[0036] The rack for placing the heat exchanger fins 1 is moved to a position close to the mounting main board 7. The first guiding column 22 extends outwards and passes through the guiding hole 11 of the heat exchanger fins 1. At the same time, the negative pressure generating device 6 makes the position of the sheet-taking part 3 generate negative pressure to suck and hold the heat exchanger fins 1 tightly.

[0037] The mounting main board 7 moves downward to move the heat exchanger fins 1 to the lower bracket 9. Before the first guiding column 22 comes into contact with the adjacent heat exchanger fin above, the first guiding column 22 retracts inwards to avoid interference with the adjacent heat exchanger fin above.

[0038] The avoidance grooves 72 correspond to the clamping structures 91 that protrude upward on the bracket 9. The mounting main board 7 moves downward until the heat exchanger fins 1 are moved to the preset installation position. The negative pressure generating device 6 stops generating negative pressure, the sheet-taking part 3 releases the heat exchanger fins 1, and the bracket 9 moves forward and drives the already installed heat exchanger fins 1 to separate from the sheet-taking part 3 and the guiding part 2.

[0039] The above embodiments are only the preferred solutions of the present utility model, and the present utility model may also have other implementation solutions. Those skilled in the art can also make equivalent deformations or replacements without departing from the spirit of the present utility model, and these equivalent deformations or replacements are all included within the scope set by the claims of this application.
