Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to a radiator processing device, especially a radiator pipe-insertion fixture. Background Technology

[0002] In existing technologies, some heat sinks employ a structure with fins mounted on copper tubes, and a tube-threading device is used to connect the copper tubes and fins. During processing, the device uses a cam mechanism to cause a connecting plate to reciprocate up and down. A fixing device is located on the side of the connecting plate, which secures the copper tube and positions it perpendicular to the fins, thus allowing the fins to be threaded through. However, this method can only thread one fin at a time, resulting in low threading efficiency and high energy consumption. Summary of the Invention

[0003] The purpose of this utility model is to provide a radiator tube-insertion fixture, which aims to solve the technical problem of low tube-insertion efficiency in existing tube-insertion fixtures.

[0004] This utility model discloses a radiator tube-insertion fixture, comprising a base plate. At least two support bars are spaced apart along the length of the base plate. A positioning plate is provided on the support bars. A positioning groove is provided on the upper surface of the positioning plate. A pressing device is provided above the positioning plate. The pressing device includes a lifting drive device. The power output end of the lifting drive device is connected to a mounting plate. Two vertical plates are vertically connected to the lower side of the mounting plate. A pressure plate is vertically connected to the lower side of the vertical plates. The pressure plate is parallel to the bottom surface of the positioning groove. Several through holes are spaced apart on the pressure plate. A positioning pin is provided downward on the left and right sides of the front part of the pressure plate and the left part of the pressure plate. The lower end of any positioning pin is provided with an arc surface, a conical surface, or a spherical surface.

[0005] Furthermore, the mounting plate is provided with mounting holes for connection to the lifting drive device.

[0006] Furthermore, the support bar has a cross-section in the shape of a right trapezoid, with both the upper and lower bases of the trapezoid perpendicular to the substrate.

[0007] Compared with the prior art, the advantages of this utility model are positive and obvious. This utility model provides a radiator tube-insertion fixture with a simple structure and convenient operation, enabling multiple fins to be inserted into copper tubes at once, greatly improving work efficiency, reducing manual labor intensity, and lowering energy consumption.

[0011] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0012] like Figures 1-3 As shown, a radiator tube-insertion fixture of this utility model includes a base plate 1. At least two support bars 2 are spaced apart along the length of the upper side of the base plate 1. A positioning plate 3 is provided on the support bars 2. A positioning groove 4 is provided in the upper surface of the positioning plate 3. A pressing device is provided above the positioning plate 3. The pressing device includes a lifting drive device (not shown in the figure). The power output end of the lifting drive device is connected to a mounting plate 5. Two vertical plates 6 are vertically connected to the lower side of the mounting plate 5. A pressure plate 7 is vertically connected to the lower side of the vertical plates 6. The pressure plate 7 is parallel to the bottom surface of the positioning groove 4. A number of through holes 8 are spaced apart on the pressure plate 7. A positioning pin 9 is provided downward on the left and right sides of the front part of the pressure plate 7 and the left part of the pressure plate 7. The lower end 10 of any positioning pin 9 is provided with an arc surface, a conical surface, or a spherical surface.

[0013] Furthermore, the mounting plate 5 is provided with mounting holes for connection to the lifting drive device.

[0014] Furthermore, the support bar 2 has a cross-section in the shape of a right trapezoid, with both the upper and lower bases of the right trapezoid perpendicular to the base plate 1.

[0015] Specifically, the lifting drive device and other components in this embodiment all adopt well-known solutions in the prior art, which are already known to those skilled in the art and will not be described in detail here.

[0016] The working principle of this embodiment:

[0017] This utility model is used for the insertion of fins 13 and copper pipes 12. The positioning groove 4 is adapted to the radiator base plate 11. During operation, the assembled radiator base plate 11 and copper pipes 12 are placed in the positioning groove 4. First, multiple fins 13, such as five, are neatly placed on the upper side of the copper pipes 12. The gap between the fins 12 is maintained by sleeves, which are fixed on the upper side of the openings of the fins 12. At this time, the bottommost fin 13 is fitted onto the upper end of the copper pipe 12 but has not yet been inserted. Then, the lifting drive device is activated. The lifting drive device drives the pressure plate 6 to move down through the mounting plate 5 and the vertical plate 6. The fins 13 are moved down by the pressure of the pressure plate 6 and are sequentially fitted into the copper pipes 12, with an interference fit. Multiple through holes 8 on the pressure plate 7 are also fitted into each copper pipe 12 until the fins 13 are pressed into the bottom of the copper pipes 12. The lifting drive device drives the pressure plate 6 to rise. Then, multiple fins 13 are placed on the upper side of the copper pipes 12, and the insertion is carried out in the same way as above. During the pressing process, the positioning pin 9 can align the fins 13 through the arc surface, preventing the upper and lower fins 13 from being misaligned.

[0018] The fins 13, copper pipes 12, and radiator base plate 11 can be parallel or inclined without restriction.

[0019] This utility model provides a radiator tube insertion fixture with a simple structure and convenient operation. It allows multiple fins 13 to be inserted into the copper tube 12 at once, which greatly improves work efficiency, reduces manual labor intensity, and lowers energy consumption.
