Description

Technical Field

[0001] The utility model relates to the technical field of fin tube threading positioning, in particular to an auxiliary device for positioning fin tube threading of a heat exchanger. Background Art

[0002] A fin is a metal sheet with relatively strong thermal conductivity added to the surface of a heat exchange device that needs heat transfer. Its main function is to increase the heat exchange surface area of the heat exchange device, thereby improving the heat exchange efficiency.

[0003] However, in the prior art, when positioning the fin tube threading of the existing heat exchanger, it mainly relies on manual judgment for insertion. Personnel mainly manually insert through on a fixed frame without a specific standard to rely on. This easily leads to errors, and the inaccurate standard will affect the product quality. Moreover, the handling and lifting of this heat exchanger also bring inconvenience to the operation of personnel. Summary of the Utility Model

[0004] The utility model provides an auxiliary device for positioning fin tube threading of a heat exchanger, which solves the structural technical problems that the manual insertion by personnel without a structure for auxiliary positioning affects the product quality and the handling and lifting of the heat exchanger are inconvenient.

Four first hydraulic expansion rods are arranged on the top of the bottom plate. A base is arranged between the tops of the four first hydraulic expansion rods. Four second hydraulic expansion rods are fixed at the four corners of the top of the bottom plate. The top of the bottom plate is connected with two support seats through the four second hydraulic expansion rods. A positioning auxiliary component is arranged between the opposite sides of each support seat.

[0006] The beneficial effects of the utility model are: The bottom plate mainly plays a role in facilitating support. The first hydraulic expansion rod can facilitate the up and down repeated movement of the base. The base can support the heat exchanger to rise. The second hydraulic expansion rod can drive the support seat to move up and down repeatedly. The support seat can support the positioning auxiliary component. The positioning auxiliary component can facilitate clamping and fixing the heat exchanger.

[0007] Based on the above technical solutions, the utility model can be further improved as follows.

[0008] Further, the positioning auxiliary component includes two sliding columns, and the two sliding columns are arranged between the opposite sides of the two support seats.

[0009] The beneficial effect of adopting the above further solution is: The sliding column can facilitate fixing and limiting the movement track of the moving plate, and is convenient for its horizontal repeated movement.

[0010] Further, a third hydraulic expansion link is provided near the other two sides on the opposite side of each of the support bases.

[0011] The beneficial effect of adopting the above further scheme is that the third hydraulic expansion link can facilitate the lateral repeated movement of the limit moving plate.

[0012] Further, a limit moving plate is connected to the opposite sides of the two support bases through four third hydraulic expansion links.

[0013] The beneficial effect of adopting the above further scheme is that the limit moving plate can clamp and fix both sides of the heat exchanger.

[0014] Further, a positioning port area is provided on one side of each of the limit moving plates.

[0015] The beneficial effect of adopting the above further scheme is that the positioning port area can facilitate the auxiliary personnel to position the positional relationship of both sides of the insertion, which brings convenience to the operation of the personnel.

[0016] Further, two moving round holes are provided near the top on one side of each of the limit moving plates.

[0017] The beneficial effect of adopting the above further scheme is that the moving round holes can facilitate the sliding column to pass through.

[0018] Beneficial effects: By using the first hydraulic expansion link, the base can lift the heat exchanger. By using the second hydraulic expansion link, the support base can be lowered, so that the positioning and auxiliary assembly can clamp and fix the heat exchanger, and then rise for insertion and positioning. In this way, a standard structure can be provided for the personnel operation, and errors can be prevented as much as possible, ensuring the precise standard and product quality. The up and down movement and clamping and fixing also bring convenience to the operation of the personnel.
