Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger production equipment, in particular to an automatic positioning device for heat exchanger fins. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, so that the fluid temperature reaches the specified process indicators to meet the needs of process conditions. A heat exchanger is mainly composed of heat exchange tubes and fins. When producing heat exchangers, a large number of fins need to be installed on the heat exchange tubes, and the spacing between each fin needs to be equal. In order to improve processing efficiency and ensure positioning accuracy, providing an automatic positioning device for heat exchanger fins is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides an automatic positioning device for heat exchanger fins, which solves the technical problems of low efficiency and low positioning accuracy when installing fins on heat exchange tubes in the existing technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic positioning device for heat exchanger fins, comprising a base plate, a boss fixedly provided on the base plate, a positioning rod fixedly provided at the center of the boss, a pair of side plates provided on both sides of the boss, and a plurality of fin positioning assemblies mirror-imaged on the pair of side plates;

[0005] The fin positioning assembly includes an opening on the side panel, in which a support plate is hinged via an axis. The support plate is divided into a first state, a second state, and a third state according to the inclination angle. When the support plate is in the first state, it will not contact the fins sliding on the heat exchange tube. When the support plate is in the second state and the third state, it can support the fins on the heat exchange tube. When the support plate is in the third state, it can place the support plate above it in the second state.

[0006] Preferably, the support plate is in the first state in its natural state, and is in the third state after one end of the support plate is pressed down by the fin, and the lowermost support plate cannot be in the first state.

[0007] Preferably, a support rod is fixedly provided below one end of the support plate on the outer side of the side plate. When the support plate is in the third state, the support rod on the upper support plate can be pushed to make the upper support plate in the second state. A support block is fixedly provided in the opening, and the support plate can be in the third state when it contacts the support block.

[0008] Preferably, the lower end of the support rod is spherical.

[0009] Preferably, a fixing block is fixedly provided on the outer side below the side plate, and the support rod on the lowermost supporting plate can contact the fixing block.

[0010] The utility model provides an automatic positioning device for heat exchanger fins, which has the following beneficial effects: by inserting the heat exchange tube on the positioning rod, the heat exchange tube can be made parallel to a pair of side plates, and the fin is inserted into the outside of the heat exchange tube from above and can contact the lowest support plate after free drop. The lowest support plate can be in the third state after lifting the fin. At this time, the upper support plate can be in the second state under the action of the support rod, and inserting the fin again can make it in the third state. Similarly, multiple fins can be inserted into the heat exchange tube, and the spacing between each fin is guaranteed by the support plate, thereby realizing automatic positioning, improving production efficiency, and ensuring positioning accuracy.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] See also Figure 1-2 The utility model provides a technical solution: an automatic positioning device for heat exchanger fins, comprising a base plate 1, a boss 2 fixedly provided on the base plate 1, a positioning rod 3 fixedly provided at the center of the boss 2, a heat exchange tube can be fixed on the boss 2 by inserting it on the positioning rod 3, a pair of side plates 4 are provided on both sides of the boss 2 on the base plate 1, and a plurality of fin positioning components are mirror-imaged on the pair of side plates 4;

[0016] The fin positioning assembly includes an opening 5 on the side panel 4, and a support plate 6 is hinged in the opening 5 through an axis. The support plate 6 is divided into a first state a1, a second state a2, and a third state a3 according to the inclination angle. When the support plate 6 is in the first state a1, it will not contact the fins sliding on the heat exchange tube. When the support plate 6 is in the second state a2 and the third state a3, it can support the fins on the heat exchange tube. When the support plate 6 is in the third state a3, the support plate 6 above it can be in the second state a2.
