Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to tooling fixtures, especially a support fixture for assembling heat sinks of cooler tube bundles. Background Technology

[0002] Cooler fin installation refers to the process of mounting heat sink fins onto the cooler tube bundle. During installation, the heat sink fins are first placed in the positioning bracket, and then the fins are expanded and secured. However, in existing technology, before the heat sink fins are firmly fixed in the positioning bracket, the fins are thin, flexible, and vary in length, resulting in insufficient support at the bottom. This leads to bending and deformation of the heat sink fins, resulting in poor product quality and low production efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide a support fixture for assembling heat sinks in a cooler tube bundle. This support fixture aims to solve the technical problem that heat sinks are prone to bending and deformation during the assembly process in the prior art.

[0004] This utility model discloses a support fixture for assembling heat sinks in a cooler tube bundle. It includes a first connecting device, a second connecting device, and a base. The first and second connecting devices are symmetrically arranged. Each device includes a horizontal plate, with a vertical plate vertically connected to its lower side. A soft pad is provided on the lower surface of the horizontal plate and the inner surface of the vertical plate. The lower side of the vertical plate is connected to the upper end of a connecting rod, and the lower end of the connecting rod is connected to the upper end of a bolt. A nut and a washer are connected to the bolt, with the washer located above the nut. The base is mounted on the two washers. A groove is provided on each end face of the base, and the grooves at both ends of the base are respectively engaged with the two bolts. A support plate is mounted on the base, located between the two bolts.

[0005] Furthermore, the soft pad is a rubber pad.

[0006] Furthermore, both the horizontal and vertical plates are made of carbon steel plates with a thickness of 5mm.

[0007] Compared with existing technologies, this invention offers positive and significant advantages. First, the first and second connecting devices are hoisted onto both sides of the positioning seat, with the lower surface of the horizontal plate contacting the upper surface of the positioning seat for hoisting support. A soft pad prevents friction with the positioning seat. Then, a base is installed between the two bolts, and a support plate is placed on the base. Next, the heat sink is placed into the positioning seat, supported by the support plate. The support plate provides good rigidity, reducing bending deformation of the heat sink and thus improving production quality and efficiency. After the heat sink is placed, it is expanded and fixed. Once the expansion and fixing are complete, the fixture can be disassembled. Attached Figure Description

[0010] 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.

[0011] like Figure 1-Figure 2 As shown, a support fixture for assembling heat sinks of a cooler tube bundle according to the present invention includes a first connecting device 1, a second connecting device 2, and a base 3. The first connecting device 1 and the second connecting device 2 are symmetrically arranged. Each of the first connecting device 1 and the second connecting device 2 includes a horizontal plate 5. A vertical plate 6 is vertically connected to the lower side of the horizontal plate 5. A soft pad 12 is provided on the lower surface of the horizontal plate 5 and the inner side of the vertical plate 6. The lower side of the vertical plate 6 is connected to the upper end of a connecting rod 7. The lower end of the connecting rod 7 is connected to the upper end of a bolt 8. A nut 9 and a washer 10 are connected to the bolt 8. The washer 10 is located on the upper side of the nut 9. The base 3 is set on the two washers 10. A groove 11 is provided on each end face of the base 3. The grooves 11 at both ends of the base 3 are respectively engaged with the two bolts 8. A support plate 4 is provided on the base 3 and is located between the two bolts 8.

[0012] Furthermore, the soft pad 12 is a rubber pad.

[0013] Furthermore, both the horizontal plate 5 and the vertical plate 6 are made of carbon steel plates with a thickness of 5mm.

[0014] Specifically, in this embodiment, the bolt 8, nut 9, washer 10, rubber pad, carbon steel plate, etc., 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.

[0015] The working principle of this embodiment:

[0016] During operation, the first connecting device 1 and the second connecting device 2 are first hoisted onto both sides of the positioning seat (not shown in the figure). The lower surface of the horizontal plate 5 contacts the upper surface of the positioning seat, providing hoisting support. The soft pad 12 prevents rubbing against the positioning seat. Then, the base 3 is installed between the two bolts 8, and the support plate 4 is placed on the base 3. Next, the heat sink is placed in the positioning seat, supported by the support plate 4. The support plate 4 has good rigidity, reducing bending deformation of the heat sink and thus improving production quality and efficiency. After the heat sink is placed, it is expanded and fixed. After expansion and fixing, the fixture can be disassembled.

[0017] The 5mm thick carbon steel plate is high in hardness and rigidity, and not easily deformed. The shim 10 supports the base 3 and the support plate 4. The nut 9 can adjust the height of the shim 10, thereby adjusting the height of the support plate 4.
