Description

Technical Field

[0001] The utility model relates to the technical field of automotive radiator pressing, in particular to an aluminum-plastic automotive radiator pressing device. Background Art

[0002] An automotive radiator consists of three parts: an inlet chamber, an outlet chamber, and a radiator core. The coolant flows inside the radiator core, and air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat dissipated by the coolant. During the pressing process of the automotive radiator, it is necessary to align the two ends of the radiator core with the hole positions on the inlet chamber and the outlet chamber respectively, and then press-fit the guard plate, the inlet chamber, the outlet chamber, and the radiator core simultaneously by applying pressure from all around. However, the existing pressing devices have overly complex structures, with each side being driven by an independent driving mechanism respectively, resulting in high energy consumption.

[0003] In the technical solution disclosed in the Chinese patent with the authorization announcement number CN216504816U, the lateral pressing mechanism can tightly compact the radiator core to prevent the radiator core from shifting during the pressing process with the main plate, thus affecting the pressing accuracy of the radiator; the double-sided comb tooth mechanism can adjust the spacing of the fins of the radiator core to prevent the assembly quality of the radiator from being affected due to uneven arrangement of the fins; the main plate pressing mechanism can press-fit the radiator main plate to both sides of the radiator core, eliminating the cumbersome manual assembly, saving time and effort, and effectively improving the assembly efficiency and quality of the radiator.

[0004] However, this device still has deficiencies: the lateral pressing mechanism and the main plate pressing mechanism in this device need to be driven by two sets of independent driving mechanisms, resulting in still relatively high energy consumption, and when this device presses radiators of different sizes, the parameter settings of each driving structure are troublesome. Content of the Utility Model

Detailed Description of the Invention

[0024] Embodiment 1

[0025] As Figures 1 - 4As shown in the figure, a press-fitting device for an aluminum-plastic automotive radiator proposed by the present utility model includes a base 1, a telescopic plate 11, a driving assembly, an adjusting assembly, and a limiting mechanism. Two clamping plates 10 are symmetrically and slidably arranged on the base 1. The telescopic plate 11 is symmetrically arranged between the two clamping plates 10 on both sides and is perpendicular to the clamping plates 10. The two ends of the telescopic plate 11 are respectively slidably connected to the corresponding clamping plates 10 on both sides. Two chutes A with openings downward are symmetrically arranged on the clamping plates 10. On the side where the two clamping plates 10 are close to each other, two limiting grooves 1001 are symmetrically arranged on each side. Each limiting groove 1001 is communicated with the corresponding chute A on the same side. A slider A9 is slidably connected in each chute respectively. The two ends of the two groups of telescopic plates 11 are respectively inserted into the limiting grooves 1001 on the corresponding side and connected to the slider A9 on the corresponding side. The driving assembly is connected to the base 1 and simultaneously drives the two clamping plates 10 and the telescopic plate 11 to approach or move away from each other. The driving assembly includes a carriage 6 and a two-way module A7. Two groups of turntables 2 are symmetrically arranged on the base 1. Each group of turntables 2 includes two. A limiting hole 201 is arranged on each turntable 2, and the limiting holes 201 on the two turntables 2 in a group are symmetric about the axis between the two turntables 2 on both sides. Two carriages 6 are symmetrically arranged in the base 1 and are slidable thereon. A transverse groove is arranged on the carriage 6. Two pins 8 are symmetrically and slidably arranged in each transverse groove respectively. Each pin 8 is inserted into the limiting hole 201 on the corresponding side and is slidably connected to its inner wall. Each pin 8 is inserted into the slider A9 on the corresponding side and is rotatably connected thereto. The two-way module A7 is arranged in the base 1, and the two carriages 6 on both sides are respectively connected to the two sliders of the two-way module A7. The adjusting assembly is connected to the base 1 and includes two groups of motors 4. Each turntable 2 is rotatably connected to the base 1, and an external gear ring 3 is coaxially connected to the outer part of each turntable 2. The external gear rings 3 on the two turntables 2 in the same group are meshed with each other. The motor 4 is connected to the base 1, and the output end of each motor 4 is coaxially connected to a gear 5 respectively. The two gears 5 are respectively meshed with the external gear ring 3 on the corresponding side. A controller is arranged in the base 1, and the controller is connected to control the two motors 4 on both sides so that the two motors 4 have the same rotational speed in the working state. The adjusting assembly adjusts the telescopic ratio of the two clamping plates 10 and the two telescopic plates 11 on both sides in the working state to press-fit radiators of different sizes. The limiting mechanism is connected to the base 1 and is located between the two clamping plates 10 on both sides. The limiting mechanism limits the fins of the radiator core in the working state. The limiting mechanism includes a plurality of clamping frames 12. The clamping frames 12 are evenly distributed, and the clamping frame 12 is a U-shaped frame. The groove of the U-shaped frame is radially perpendicular to the clamping plate 10.

[0026] In this embodiment, first, the distance between the two telescopic plates 11 on both sides is adjusted according to the size of the radiator. At this time, the motors 4 on both sides are started first. The motors 4 on both sides drive the corresponding gears 5 to rotate respectively, and then drive one side of the turntable 2 to rotate through the gears 5. The other turntable 2 rotates synchronously under the meshing drive of the external tooth ring 3. The rotation directions of the two turntables 2 on both sides in the two groups of turntables 2 are opposite, so that the opening angle of the limiting holes 201 changes. Subsequently, the fins of the radiator core are clamped on the clamping frame 12, and then guard plates are placed on both sides of the radiator core in the direction parallel to the fins. Then, an inlet chamber and an outlet chamber are placed at both ends of the radiator core respectively. The two-way module A7 is started, and the two-way module A7 drives the two sliding frames 6 to approach synchronously. At this time, the pin shaft 8 slides in the limiting holes 201 and the transverse grooves on the sliding frames 6, thereby driving the sliding block A9 to slide. The sliding of the sliding block A9 drives the two telescopic plates 11 to approach and contract with each other. That is, at this time, while the two clamping plates 10 approach each other, the two telescopic plates 11 approach each other. The two clamping plates 10 abut from the ends where the inlet chamber and the outlet chamber are far away from each other, and the two telescopic plates 11 abut from the sides where the two guard plates are far away from each other. That is, the pressing of the radiator is completed at one time.

[0027] Embodiment 2

[0028] As Figure 1 and Figure 4 shown, a pressing device for an aluminum-plastic automotive radiator proposed by the present utility model further includes a distance adjustment component compared with Embodiment 1. The distance adjustment component is connected to the base 1 and synchronously drives and connects each clamping frame 12 to adjust the distance between adjacent two clamping frames 12 at equal intervals. The distance adjustment component includes a scissor-type telescopic frame 13 and a two-way module B15. Each connecting rod end transfer part of the scissor-type telescopic frame 13 is connected with a positioning pin respectively. The bottom of the clamping frame 12 is provided with a chute B opening downward. Each positioning pin is respectively inserted into the chute B at the bottom of the corresponding side clamping frame 12 and is slidably connected with its inner wall. The bottoms of the clamping frames 12 at both ends are respectively connected with a sliding block B14. The two-way module B15 is located in the base 1, and the two sliding seats of the two-way module B15 are respectively connected with the corresponding side sliding blocks B14.

[0029] In this embodiment, when placing the radiator core, first, according to the distance between the fins of the radiator chip, the two-way module B15 is started. The two-way module B15 drives the two sliding blocks B14 on both sides to approach. At this time, all the clamping frames 12 contract or move away at equal intervals under the drive of the scissor-type telescopic frame 15. Subsequently, the bottoms of the fins in the radiator core are respectively clamped into the corresponding side clamping frames 12, and the positions of the fins are accurately positioned by using the clamping frames 12 to prevent the fins from shifting during the pressing process and ensure that the fins are arranged neatly.

[0030] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
