Technical Field
[0001] This utility model relates to the field of radiator technology, specifically to a metal pad assembly device for automotive radiators. Background Technology
[0002] In automotive cooling systems, the radiator, as a core heat dissipation component, directly affects the engine's operational stability through its sealing performance. The assembly quality of the metal gasket and the damping pad is a crucial factor in ensuring the radiator's seal. The metal gasket must be precisely pressed into place to ensure a proper fit between the sealing surfaces, while the damping pad must be stably embedded in the mounting holes to buffer vibrations. The assembly precision of both directly affects the radiator's lifespan, placing stringent requirements on the integration and precision of the assembly process.
[0003] After reviewing the latest relevant equipment, this application believes that the existing equipment for assembling metal pads and shock absorbers has obvious limitations: the installation of shock absorbers and the pressing of metal pads are usually carried out separately by two separate machines, resulting in large equipment size, lack of integrated design, low degree of integration, and large equipment footprint. Therefore, this application proposes another technical solution to address this problem. Utility Model Content

It integrates the rubber ring pressing and metal pad pressing mechanisms, reducing equipment size and cost. The controller precisely controls the stroke of the metal pad pressing cylinder, flexibly adapting to the pressing depth. It solves the problem that the installation of shock absorber pads and the pressing of metal pads are carried out separately by two separate devices, resulting in a large equipment size. The integration level also reduces the equipment's footprint.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal pad assembly device for an automotive radiator, comprising a press-fit assembly mechanism, wherein the press-fit assembly mechanism includes a mounting plate, a start button is provided on the top of the mounting plate, and a mounting bracket is connected to the top of the mounting plate;

[0008] To achieve the above technical solution, the controller is used for control, the positioning fixture works with the fixing claw to firmly clamp the heat sink body, and the controller coordinates the actions of each mechanism to achieve precise and synchronized assembly.
[0009] In one embodiment of this utility model, the lower pressure plate is located directly above the rubber ring pressing mechanism, and their positions are corresponding.
[0010] To achieve the above technical solution, the lower pressure plate and the rubber ring pressing mechanism are precisely aligned, ensuring that the metal pad is coaxial with the shock-absorbing pad during pressing, avoiding misalignment caused by offset, and significantly improving the accuracy and sealing of radiator component assembly.
[0011] In one embodiment of this utility model, the controller is electrically connected to both the rubber ring pressing mechanism and the metal pad pressing cylinder.
[0012] To achieve the above technical solution, the controller links the two through electrical signals, realizing precise timing matching between the pressing of the rubber ring and the pressing of the metal pad, avoiding action conflicts, ensuring a smooth and orderly assembly process, and significantly improving the coordination and precision of radiator assembly.
[0013] In one embodiment of this utility model, a mounting hole is provided on the outer side of the radiator body, and the mounting hole can be connected to a metal pad and a shock-absorbing pad.
[0014] The above technical solution ensures that the mounting holes are compatible with both metal pads and shock-absorbing pads, establishes a consistent assembly benchmark, reduces equipment debugging procedures, guarantees the coaxiality of both during installation, and improves the assembly accuracy and efficiency of the radiator.
[0015] In one embodiment of this utility model, the top of the positioning fixture is provided with a mounting groove that is adapted to the heat sink body, and the heat sink body is connected to the positioning fixture through the mounting groove.
[0016] The above technical solution ensures that the mounting slot and the radiator body are precisely matched, guaranteeing that they are stable and without displacement during assembly. This provides a consistent reference for pressing in the rubber ring and pressing in the metal pad, effectively improving the assembly positioning accuracy and the fit of the parts.
[0017] In one embodiment of this utility model, a through groove is provided on the top of the mounting bracket, and the metal pad press-fit cylinder is connected to the mounting bracket through the through groove.
[0018] The above technical solution ensures precise alignment between the lower pressure plate and the rubber ring pressing mechanism, thereby improving the stability and reliability of the pressing action.
[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0020] This automotive radiator metal pad assembly equipment uses positioning fixtures to lock the radiator in place, preventing assembly misalignment. The integrated rubber ring pressing and metal pad pressing mechanisms reduce equipment size and cost. The controller precisely controls the stroke of the metal pad pressing cylinder, flexibly adapting to the pressing depth. During pressing, the elastic structure retracts synchronously to avoid damaging the shock-absorbing pad. The automated linkage of multiple mechanisms enables seamless connection of the two-part assembly, ensuring that the metal pad is pressed in place while reducing the damage rate of parts, significantly improving the radiator assembly accuracy, consistency, and production efficiency.

[0024] 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.
[0025] Please see Figure 1-2 The metal pad assembly equipment for an automotive radiator in this embodiment includes a press-fit assembly mechanism, which includes a mounting plate. A start button 2 is provided on the top of the mounting plate, and a mounting bracket 3 is connected to the top of the mounting plate.
[0026] In this embodiment, a rubber ring pressing mechanism 4 is connected to the top of the mounting plate, a positioning fixture 5 is connected to the top of the rubber ring pressing mechanism 4, a metal pad pressing cylinder 6 is connected to the top of the mounting frame 3, a through groove is provided on the top of the mounting frame 3, and the metal pad pressing cylinder 6 is connected to the mounting frame 3 through the through groove to ensure that the lower pressing plate 7 and the rubber ring pressing mechanism 4 are accurately aligned, thereby improving the stability and reliability of the pressing action. The lower pressing plate 7 is provided at the output end of the metal pad pressing cylinder 6.
[0027] The lower pressure plate 7 is located directly above the rubber ring pressing mechanism 4, and their positions are corresponding. The lower pressure plate 7 and the rubber ring pressing mechanism 4 are precisely aligned to ensure that the metal pad is coaxial with the shock-absorbing pad during pressing, avoiding misalignment caused by offset, and significantly improving the accuracy and sealing of the radiator parts assembly. A controller 8 is provided on one side of the mounting bracket 3. The controller 8 is electrically connected to the rubber ring pressing mechanism 4 and the metal pad pressing cylinder 6 respectively. The controller 8 links the two through electrical signals to achieve precise timing matching of rubber ring pressing and metal pad pressing, avoiding action conflicts and significantly improving the coordination and accuracy of radiator assembly.
[0028] In this embodiment, the top of the positioning fixture 5 is provided with a heat sink body 9, and the top of the mounting plate is connected with a fixing claw 101. The controller 8 is used for control. The positioning fixture 5, together with the fixing claw 101, firmly clamps the heat sink body 9. The top of the positioning fixture 5 is provided with an installation groove that matches the heat sink body 9. The heat sink body 9 is connected to the positioning fixture 5 through the installation groove. The installation groove and the heat sink body 9 are precisely matched to ensure that it is stable and without displacement during the assembly process. This provides a consistent reference for pressing in the rubber ring and pressing in the metal pad, effectively improving the assembly positioning accuracy and the fit of the parts.
[0029] The radiator body 9 has mounting holes on its outer side. These mounting holes can connect metal pads and shock-absorbing pads. The mounting holes are uniformly compatible with both metal pads and shock-absorbing pads, establishing a consistent assembly benchmark, reducing equipment debugging procedures, ensuring the coaxiality of the two during installation, and improving the assembly accuracy and efficiency of the radiator. The controller 8 coordinates the actions of each mechanism to achieve precise and synchronized assembly.
[0030] The working principle of the above embodiments is as follows:
[0031] This automotive radiator metal pad assembly equipment precisely fits the radiator body 9 through the mounting groove on the top of the positioning fixture 5. The rubber ring pressing mechanism 4 and the metal pad pressing cylinder 6 are integrated into the same mounting bracket 3 and mounting plate. During the pressing process, the metal pad pressing cylinder 6 drives the lower pressing plate 7 to move. Its matching elastic telescopic structure is realized through cylinder stroke control and mechanism adaptation. It automatically retracts when pressing the metal pad to avoid bumping the assembled shock-absorbing pad, effectively reducing the damage rate of parts. The controller 8 synchronously links the rubber ring pressing mechanism 4 and the pressing cylinder, which can precisely control the stroke of the metal pad pressing cylinder 6 and flexibly adjust the pressing depth of the metal pad to ensure that the metal pad is completely embedded in the mounting hole of the radiator body 9, ensuring assembly consistency. The lower pressing plate 7 and the rubber ring pressing mechanism 4 are precisely aligned. The start button 2 simplifies the operation process. The full-process automation reduces human intervention errors and realizes the integration of shock-absorbing pad pressing and metal pad assembly, which greatly reduces the space occupied by the equipment and reduces the equipment procurement and maintenance costs.
