Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing tooling technology, and in particular to a radiator core flaring tooling. Background Technology

[0002] Radiators are key components in heat exchange systems, and the quality of their manufacturing process directly affects product performance. Among these processes, flaring the radiator core tube openings is a crucial step in ensuring a tight connection with the manifold. Various flaring fixtures are widely used in the industry. These fixtures are maturely designed and can reliably and stably fix the flaring gears on the spindle, achieving precision machining of the tube openings through rotation. This makes a significant contribution to ensuring the quality and consistency of radiator products. Traditional fixing methods typically employ bolt fastening or integrated welding. The advantages of this design are its simple structure, strong connection rigidity, and effective torque transmission under normal operating conditions, ensuring machining accuracy. However, in actual high-frequency, high-volume production processes, metal debris such as aluminum inevitably adheres to and accumulates on the teeth of the flaring gears. If not cleaned promptly, this will affect the flaring quality of subsequent products. For fixtures using traditional fixing methods, the disassembly and reassembly processes for cleaning and maintenance often require additional tools and are time-consuming.

[0003] Therefore, this application provides a heat sink core flaring tool to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a radiator core flaring fixture, which aims to solve the problem that the flaring gear of the existing flaring fixture is inconvenient to disassemble, resulting in long cleaning and maintenance time, affecting production efficiency and product quality.

[0005] To achieve the above objectives, this application provides the following technical solution: a radiator core flaring tooling, comprising a double-layer hollow spindle, wherein the double-layer hollow spindle comprises an outer rod coaxially arranged and an inner rod rotatable within the outer rod; The flared gear is detachably mounted on the double-layer hollow spindle; A locking and unlocking mechanism is used to lock or unlock the flared gear onto or from the double-layered hollow spindle. The locking and unlocking mechanisms include: Positioning holes are drilled on the outer rod; Limiting holes are provided on the inner rod; A set of limiting plates that can pass through positioning holes and limiting holes to lock the flared gear; The inner wall of the limiting hole of the inner rod is provided with a first inclined surface, and the limiting plate is provided with a second inclined surface that cooperates with the first inclined surface; When the inner rod is rotated, the first and second inclined surfaces interact to generate thrust, which pushes the limit plate outward, thereby initiating the unlocking action. This enables tool-free quick disassembly and assembly, greatly improving maintenance efficiency.

[0006] Preferably, the inner wall of the positioning hole of the outer rod is provided with a third inclined surface for guiding the limiting plate to disengage, and a plane is provided on the side opposite to the third inclined surface for bearing the processing force in the locked state, which takes into account both reliable bearing during operation and smooth guidance during disassembly.

[0007] Preferably, the limiting plate is also connected to a guide plate to form a U-shaped or gate-shaped structure, and a pre-tightening spring is provided to apply a pre-tightening force to the limiting plate to keep it in the locked position, so that the locking part is more stable in the operation and can effectively prevent accidental loosening.

[0008] Preferably, a connecting plate is fixed on the flared gear, the connecting plate has a through hole for the limiting plate to pass through, and the connecting plate has a guide groove for installing the guide plate; and one end of the inner rod is connected to a rotating handle, and the other end of the inner rod is connected to an end cap.

[0009] Preferably, the end cap and the outer rod are threaded together, and the end cap and the inner rod are rotatably connected. A torsion spring is provided at the connection, wherein the torsion spring provides a restoring force for the rotation of the inner rod, making the locking more secure.

[0010] Preferably, the inner rod has a hollow structure with fluid channels inside that can be used to transport coolant or lubricant, which can realize internal cooling function, help improve the machining quality of the workpiece and extend the tooling life.

[0011] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a wedge-shaped drive mechanism consisting of the first inclined surface of the inner rod and the second inclined surface of the limiting plate is set up to enable quick disassembly and assembly of the flared gear. Compared with the existing technology that requires tools for disassembly and fixing, the unlocking process does not require any external tools, the operation steps are simplified, and the downtime caused by cleaning and maintenance is significantly shortened, thereby improving the overall operating efficiency of the production line.

[0012] This invention provides convenient conditions for high-frequency cleaning and maintenance of flared gears, enabling them to maintain a clean working state for a long time. This effectively avoids quality problems such as flaring size deviation or inner wall scratches that may be caused by the accumulation of metal debris, thereby ensuring the long-term stability and consistency of product quality in mass production.

[0013] In this invention, the main components of the locking and unlocking mechanism are integrated inside the double-layer hollow main shaft, and the external structure is simpler and more regular, avoiding potential safety hazards caused by exposed components. The torsion spring set between the end cover and the inner rod provides a reliable reset preload force for the inner rod, making the locking state clearer and more stable, simplifying operation judgment, and further improving the overall operation performance and safety of the device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] refer to Figure 1-6The diagram shows a radiator core flaring fixture. The main structure of the fixture includes a double-layer hollow spindle 10 and a flared gear 20 detachably mounted on the spindle. The double-layer hollow spindle 10 is designed to enable quick assembly and disassembly. It consists of a fixed outer rod 12 and an inner rod 15 that can rotate coaxially inside the outer rod 12. This relative rotation capability is key to driving the unlocking action. For ease of manual operation, one end of the inner rod 15 is connected to a rotating handle 14 as a fixed working component. The other end of the inner rod 15 is rotatably connected to an end cap 11, and a torsion spring is provided at the connection to provide preload force for the inner rod, so as to better fix the flared gear 20. The end cap 11 and the outer rod 12 are connected by threads. A connecting plate 21 is fixed on the flared gear 20. The function of the connecting plate 21 is to provide a stable and sufficiently large mounting base, and it has a guide groove 22 for the locking component to pass through.

[0019] As one embodiment of this invention, a locking and unlocking mechanism is provided to facilitate quick assembly and disassembly of the flared gear. This mechanism consists of a U-shaped or gate-shaped locking element and a corresponding slot. The locking element comprises a limiting plate 24 and a guide plate 23 connected to it. The presence of the guide plate 23 ensures the stability of the locking element's posture during insertion and removal, preventing jamming. Furthermore, the connecting plate 21 has a guide groove 22 adapted to the guide plate 23. The outer rod 12 has a positioning hole 13, the inner wall of which is designed as a surface with dual functions: one side is a flat surface, its function being to bear the main working force during flaring to ensure the rigidity of the lock; the other side is a third inclined surface, its function being to provide a smooth guiding ramp during disassembly. The inner rod 15 has a limiting hole 16 corresponding to the positioning hole 13, and its inner wall has a first inclined surface for driving unlocking. The first inclined surface and the second inclined surface on the side wall of the limiting plate 24 form a key wedge mechanism, which functions to convert the rotational motion of the inner rod 15 into a radial pushing force on the limiting plate 24. In addition, the mechanism also includes a preload spring 25, which functions to provide a continuous preload in the locked state to prevent accidental loosening due to equipment vibration or other reasons.

[0020] As one embodiment of this invention, and further as a preferred improvement of this invention, the inner rod 15 can be designed as a hollow tubular structure, and the fluid channel formed inside it can be used to deliver coolant or lubricant to the flared gear 20 during the processing, thereby further improving the processing quality and extending the service life of the tooling.

[0021] The working principle of this practical device is as follows: During installation, the U-shaped locking piece is first passed through the through hole on the flared gear 20. Then, the connecting plate 21 is installed onto the flared gear 20, fixing the U-shaped locking piece in place. Subsequently, the limiting plate 24 of the U-shaped locking piece passes through the positioning hole 13 and the limiting hole 16. Under the action of the pre-tension spring 25, the limiting plate 24 is pushed in and locked within the limiting hole 16, completing the locking. When disassembly is required, the rotating handle 14 is turned, and the first inclined surface of the inner rod 15 pushes the second inclined surface of the limiting plate 24, forcing it to move radially out of the limiting hole 16. Then, the operator can easily pull out the locking piece completely along the third inclined surface of the positioning hole 13. Through the above design, tool-free quick disassembly and assembly of the flared gear is achieved, making the operation extremely simple and fast, greatly improving the efficiency of maintenance and tooling replacement on the production line.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
