Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts assembly equipment, specifically a pressure plate device for fully automatic assembly of automotive radiators. Background Technology

[0002] Utility model patent CN218081317U discloses a pressure plate device for fully automatic assembly of automotive radiators. This device includes a pressure plate platform, a top frame, a hydraulic cylinder, a telescopic rod, a screw ring frame, screw rings, screws, a screw pan, bearings, hinge blocks, hinge frames, hinge shafts, mounting seats, mounting blocks, and a pressure plate mold. Two sets of screw rings are each screwed to a set of screws on their inner walls. The top of the screws is connected to the middle of the bottom of the screw pan. The bottom of the screws is rotatably connected to the top of the hinge blocks via bearings. Two sets of hinge blocks are movably connected inside the hinge frames via hinge shafts. The bottom of the two sets of hinge frames is connected to the left and right sides of the top of the mounting seat, respectively. The top of the pressure plate mold is connected to the bottom of the mounting blocks. The mounting blocks are detachably installed inside the mounting seat. By adjusting their angle and position, the pressure plate can be adapted to different working requirements, increasing the applicability of a single pressure plate mold.

[0003] When assembling the frame and fins of a car radiator, the traditional pressure plate device for fully automatic assembly addresses the issue that the strip-shaped fins naturally bend and deform. Because traditional pressure plate devices lack precise positioning mechanisms to address spatial orientation deviations of the fins, they cannot effectively correct for the spatial angle and positional offsets caused by bending when assembling the fins into the radiator frame mounting slot. This results in misalignment between the fins and the mounting slot, and forcibly pressing them in can cause fin deformation during the pressing process, affecting the overall assembly quality of the radiator. Therefore, we propose a pressure plate device for fully automatic assembly of car radiators. Utility Model Content

[0004] The purpose of this invention is to provide a pressure plate device for fully automatic assembly of automotive radiators, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure plate device for fully automatic assembly of automotive radiators includes an automatic assembly machine. The automatic assembly machine is equipped with an assembly platform and a hydraulic cylinder at its top. The assembly platform is provided with a pair of guide rails, and a bottom frame for placing the radiator frame is slidably connected between the two guide rails. The assembly platform is provided with a guide assembly for pre-placing the heat dissipation fins to be pressed. Above the guide assembly is a pushing assembly for pressing the heat dissipation fins. The assembly platform is also provided with a positioning assembly for positioning the radiator frame.

[0007] The guide assembly includes a plate spanning over the two guide rails and a pair of first guide posts slidably connected to the beginning and end ends of the plate. The plate has a guide groove, and the top edge of the guide groove is inclined.

[0008] The pushing assembly includes a push plate connected to the hydraulic cylinder and a stop plate located below the push plate, wherein the bottom end of the push plate is provided with a stop head;

[0009] The positioning component includes a base plate located below the bottom frame and several third guide posts slidably connected to the base plate. The top of the base plate is provided with several positioning protrusions, and the top of the positioning protrusions abuts against the fin mounting grooves on the radiator frame.

[0010] Preferably, the top of the assembly platform has a groove, and the positioning component is installed in the groove;

[0011] In this setup, the positioning component is installed in the groove, making the positioning component and the assembly platform structure more compact and not affecting the normal operation of other components.

[0012] Preferably, a pair of limiting plates are fixed on the assembly platform. The two limiting plates are respectively located below the first and last ends of the flat plate. The limiting plates are used to block and limit the downward movement of the flat plate.

[0013] In this setting, the limit plate prevents the radiator frame from being damaged when the flat plate moves downwards.

[0014] Preferably, the top end of the first guide post penetrates the flat plate and is provided with a stop post, the bottom end of the first guide post is fixedly connected to the assembly platform, and a first spring is sleeved on the bottom periphery of the first guide post, with the first spring located between the assembly platform and the flat plate;

[0015] This setting allows the tablet to return to its original position under the elastic force of the first spring after it is released from the pressure state, thus avoiding interference with the movement of the bottom frame and the heat sink frame.

[0016] Preferably, a pair of limiting posts are fixed to the top of the plate, and the limiting posts are used to block and limit the downward movement of the push plate;

[0017] In this setting, the limit post prevents the push plate from being pressed down excessively, ensuring the positional accuracy of the push assembly during the pressing process and avoiding damage to the heat sink fins or other components.

[0018] Preferably, the abutment is sleeved on the outside of the push plate, and a second guide post is fixed at both the left and right edges of the top of the abutment. The top of the second guide post penetrates the push plate and is provided with a baffle. A second spring is sleeved at the bottom periphery of the second guide post, and the second spring is located between the push plate and the abutment.

[0019] In this setting, the area of ​​the heat sink fins pressed by the pressing component is increased, so that the heat sink fins in a bent state can be accurately pressed, and when the hydraulic cylinder drives the pressing component to reset, the abutment plate can be reset under the action of the second spring.

[0020] Preferably, the top end of the third guide post penetrates the seat plate and is provided with a stop block, the bottom end of the third guide post is fixedly connected to the assembly platform and a third spring is sleeved on its periphery, and the third spring is located between the seat plate and the assembly platform;

[0021] In this configuration, the base plate, under the elastic force of the third spring, always presses upward against the radiator frame. The positioning protrusions tightly abut against the fin mounting slots, achieving precise positioning of the radiator frame.

[0022] Preferably, the abutment, the guide groove, and the positioning protrusion located at the rightmost end are on the same vertical plane;

[0023] In this setting, the direction of the force applied during the pressing of the push assembly is consistent with the direction of the heat sink fins and the heat sink frame, so that the heat sink fins can be smoothly pressed into the fin mounting slots of the heat sink frame.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This fully automatic assembly press plate device for automotive radiators uses an inclined slot in the guide assembly to actively correct the spatial orientation deviation of the heat dissipation fins caused by their own bending, based on the principle of inclined plane guidance. During the assembly process, the inclined slot guides the fins to gradually adjust their angle and position. In conjunction with the positioning protrusion on the positioning assembly, the positioning protrusion, the radiator frame mounting groove and the heat dissipation fins are aligned on the same vertical plane, achieving alignment of the three and effectively preventing misalignment between the heat dissipation fins and the radiator frame fin mounting groove during press-fitting.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0042] Please see Figures 1-8An automatic pressure plate device for assembling automotive radiators includes an automatic assembly machine 100, an assembly platform 110 on the automatic assembly machine 100, a hydraulic cylinder 120 at the top of the automatic assembly machine 100, a pair of guide rails 111 on the assembly platform 110, and a base frame 130 for placing the radiator frame 200 slidably connected between the two guide rails 111. The base frame 130 has a positioning groove for positioning the radiator frame 200 to facilitate the placement of the radiator frame 200. The sliding connection between the guide rails 111 and the base frame 130 facilitates the placement and position adjustment of the radiator frame 200. A guide assembly 400 for pre-placing the heat dissipation fins 300 to be pressed is provided on the assembly platform 110, a pressing assembly 500 for pressing the heat dissipation fins 300 is provided above the guide assembly 400, and a positioning assembly 600 for positioning the radiator frame 200 is provided on the assembly platform 110.

[0043] like Figures 1-4 As shown, in this utility model, the guide assembly 400 includes a flat plate 410 spanning above two guide rails 111 and a pair of first guide posts 420 slidably connected to the two ends of the flat plate 410. The top of the first guide post 420 passes through the flat plate 410 and is provided with a stop post. The bottom of the first guide post 420 is fixedly connected to the assembly platform 110. A first spring 421 is sleeved on the outer periphery of the bottom of the first guide post 420. The first spring 421 is located between the assembly platform 110 and the flat plate 410. The first guide post 420 cooperates with the first spring 421 so that the flat plate 410 can be released from the compressed state and reset upward under the elastic force of the first spring 421, preventing the flat plate 410 from interfering with the movement of the bottom frame 130 driving the radiator frame 200. A pair of limiting plates 140 are fixed on the assembly platform 110. The two limiting plates 140 are located below the beginning and end of the flat plate 410, respectively. The limiting plates 140 are used to block and limit the downward movement of the flat plate 410, so as to prevent the flat plate 410 from damaging the heat sink frame 200 when it moves downward.

[0044] like Figure 4 As shown, specifically, a guide groove 411 is provided on the plate 410. The top edge of the guide groove 411 is inclined. The inclined groove structure of the guide groove 411 can actively correct the bending heat dissipation fins 300 with spatial orientation deviation by using the inclined plane guiding principle, and guide the fins to gradually adjust their angle and position so that they can be accurately aligned with the fin mounting groove of the heat sink frame 200.

[0045] like Figure 1 , Figure 2 and Figure 5As shown, the pushing assembly 500 further includes a push plate 510 connected to the hydraulic cylinder 120 and a stop plate 520 located below the push plate 510. The bottom end of the push plate 510 is provided with a stop head 511. The stop plate 520 is sleeved on the outside of the push plate 510, with the bottom end of the stop plate 520 flush with the bottom end of the stop head 511. Second guide posts 521 are fixed to the left and right edges of the top of the stop plate 520. The top of the second guide post 521 penetrates the push plate 510 and is provided with a baffle. A second spring 522 is sleeved on the bottom periphery of the second guide post 521. The second spring 522 is located between the push plate 510 and the stop plate 520. When the hydraulic cylinder 120 pushes the push plate 510 downwards, the push plate 510 drives the stop plate 520. The pusher assembly 500 moves towards the heat dissipation fins 300 placed in the guide groove 411. The abutment plate 520 increases the area of ​​the pusher assembly 500 pressing the heat dissipation fins 300, allowing the bent heat dissipation fins 300 to still be accurately pressed by the pusher assembly 500, thus smoothly pressing the heat dissipation fins 300 into the guide groove 411. As the pusher assembly 500 continues to move downward and the abutment plate 520 abuts against the top of the plate 410, the pusher plate 510 can continue to push the abutment head 511 downward, so that the abutment head 511 is inserted into the guide groove 411. At this time, the heat dissipation fins 300 in the guide groove 411 will be pressed into the fin mounting groove of the radiator frame 200, completing the installation of the radiator frame 200. When the hydraulic cylinder 120 drives the pusher assembly 500 upward to reset, the abutment plate 520 will reset under the action of the second spring 522.

[0046] like Figure 4 As shown, in addition, a pair of limiting posts 412 are fixed at the top of the plate 410. The limiting posts 412 are used to block and limit the downward movement of the push plate 510. The limiting posts 412 can prevent the push plate 510 from being pressed down too much, ensure the position accuracy of the pressing assembly 500 during the pressing process, and avoid damage to the heat sink fins 300 or other components due to excessive pressing.

[0047] like Figure 1 and Figure 6As shown, it is worth noting that the top of the assembly platform 110 has a groove 112, and the positioning component 600 is installed in the groove 112. The positioning component 600 includes a base plate 610 located below the base frame 130 and several third guide posts 620 slidably connected to the base plate 610. The top of the base plate 610 is provided with several positioning protrusions 611, the top of which abuts against the fin mounting groove on the radiator frame 200. The top of the third guide posts 620 penetrates the base plate 610 and is provided with a stop. The bottom of the third guide posts 620 is fixedly connected to the assembly platform 110 and a third spring 621 is sleeved on its periphery. The third spring 621 is located between the base plate 610 and the assembly platform 110. Under the elastic force of the third spring 621, the base plate 610 can always press against the radiator frame 200 upwards. Thus, when the base frame 130 is pushed to move the radiator frame 200, the positioning protrusions 611 abut against the fin mounting groove of the radiator frame 200, thereby achieving precise positioning of the radiator frame 200.

[0048] like Figure 2 As shown, it is worth noting that the positions of the abutment 511, the guide groove 411, and the positioning protrusion 611 at the far right are on the same vertical plane, ensuring that the direction of the force exerted by the pressing assembly 500 during pressing is consistent with the direction of the heat dissipation fins 300 and the heat sink frame 200, so that the heat dissipation fins 300 can be smoothly pressed into the fin mounting groove of the heat sink frame 200.

[0049] In this embodiment, the pressure plate device for fully automatic assembly of automotive radiators is used as follows: First, the radiator frame 200 is placed on the base frame 130. Using the sliding connection between the guide rail 111 and the base frame 130, the radiator frame 200 is pushed below the guide assembly 400. At this time, under the elastic force of the third spring 621, the seat plate 610 in the positioning assembly 600 abuts tightly against the fin mounting groove on the radiator frame 200 through the positioning protrusion 611, achieving precise positioning of the radiator frame 200. Next, the radiator fins 300 to be pressed are pre-placed in the guide groove 411 of the guide assembly 400. Then, the hydraulic cylinder 120 is activated, causing the hydraulic cylinder 120 to push the push plate 510 downwards. The push plate 510 drives the abutment plate 520 towards the placement... The heat dissipation fins 300 move in the guide groove 411. Then, as the push plate 510 moves downward, the abutment plate 520 increases the pressing area, so that the bent heat dissipation fins 300 are accurately pressed. When the abutment plate 520 abuts against the top of the plate 410, the push plate 510 continues to push the abutment 511, pressing the heat dissipation fins 300 into the fin mounting groove of the radiator frame 200. Finally, the hydraulic cylinder 120 drives the pushing assembly 500 to reset, the abutment plate 520 resets under the action of the second spring 522, and the plate 410 resets upward under the action of the first spring 421, completing one heat dissipation fin 300 installation. Through multiple pushes of the bottom frame 130 and activation of the hydraulic cylinder 120, the assembly of multiple heat dissipation fins 300 is completed.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
