Description

Technical Field

[0001] This utility model relates to the technical field of heat sink processing equipment, and in particular to a heat sink vacuum suction cup clamping device. Background Technology

[0002] A radiator is a device that dissipates heat generated during equipment operation through heat conduction, convection, and other methods. It is widely used in equipment that requires temperature control, such as computers and car engines. Its core function is to reduce the performance degradation or damage of equipment due to overheating and to ensure stable operation of the equipment.

[0003] During the manufacturing process of the radiator, materials such as aluminum profiles and copper plates are selected according to design requirements. The materials are cut to the specified dimensions using a cutting machine, and then deburred and polished. The metal plates are stamped into fin shapes using a stamping die. The base is milled, turned, or CNC machined and fixed during processing to increase machining accuracy. The fins and base are connected using processes such as high-frequency welding and vacuum brazing. The product meets heat dissipation performance standards by passing airtightness tests, thermal resistance tests, and mechanical strength tests.

[0004] Traditional clamping devices often have fixed suction cup spacing or require manual adjustment of each one. When dealing with heat sinks of different sizes, it is necessary to replace the entire set of clamps or spend a lot of time manually adjusting them, resulting in low changeover efficiency.

When dealing with heat sinks of different sizes, it is necessary to replace the entire set of clamps or spend a lot of time manually adjusting them, resulting in low changeover efficiency.

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the limitations of the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a radiator vacuum suction cup clamping device, including a processing table; the surface of the processing table is provided with multiple sliding grooves; a slider is slidably connected to the middle of the sliding groove; a linkage rod is rotatably connected to the middle of the slider; a hydraulic cylinder is provided below the processing table; an installation ring is fixedly connected to the output end of the hydraulic cylinder; the installation ring is rotatably connected to the end of the linkage rod; a pipe runs through the middle of the slider; a suction cup is fixedly connected to the top of the pipe; the hydraulic cylinder drives the linkage rod to move the slider in the sliding groove, which can flexibly adjust the distance between the multiple suction cups to adapt to radiator plates of different sizes, reduce changeover time and cost, and increase clamping versatility. At the same time, the suction cups are connected to a vacuum pump through the pipe, and the negative pressure is used to tightly adsorb the radiator plate, reducing plate deformation caused by uneven clamping force and increasing processing accuracy.

[0008] In one embodiment of this utility model, a protective plate is fixedly connected to the top of the processing table; a movable plate is hinged to the top of the processing table; multiple buckles are fixedly connected to one side of the movable plate; a slot is opened on one side of the protective plate; a stop post is fixedly connected to the middle of the slot; the movable plate can be quickly flipped by hinged arrangement, and the buckles can be inserted into the slot and fixed by the stop post to form a closed or semi-closed protective area on the top of the processing table, reducing the splashing of debris, coolant or scrap material generated during processing and increasing operational safety.

[0009] In one embodiment of this utility model, a set of elastic cloth is fixedly connected to the middle of the slide groove; the elastic cloth is fixedly connected to the end of the slider; by tightly filling the gap between the slide groove and the slider with the elastic cloth, a barrier is formed, reducing the intrusion of cutting fluid and debris, reducing the wear and corrosion of internal components, reducing the frequency and cost of equipment maintenance, increasing the life of the slider, and the seepage of cutting fluid into the gap will cause uneven sliding resistance of the slider, resulting in jamming or displacement, thus increasing the processing quality.

[0010] In one embodiment of this utility model, a damping telescopic rod is fixedly connected to the top of the output end of the hydraulic cylinder; the damping telescopic rod is set between the hydraulic cylinder and the processing table; by setting a damping telescopic rod at the top of the output end of the hydraulic cylinder, it can retract to absorb the impact force, reduce the direct collision between the hydraulic cylinder and the processing table, reduce the wear or deformation of components such as the hydraulic cylinder and the mounting ring, and at the same time reduce the workpiece displacement caused by vibration of the processing table, and increase the stability of the connection structure.

[0013] In one embodiment of this utility model, multiple suction cups are provided; by providing multiple suction cups, the adsorption force can be dispersed, and different areas of the bottom of the heat sink can be covered by multiple points of contact, so that the workpiece is subjected to uniform force as a whole, closely adhering to the adsorption surface, reducing the risk of displacement caused by insufficient adsorption at a single point, and increasing the processing accuracy.

[0014] In one embodiment of this utility model, the water outlet is triangular in shape. The inverted triangular water outlet can guide the cutting fluid to gather towards the center of the bottom of the tank by using the inclined surface, reducing the residence time in the tank and reducing local liquid accumulation caused by slow flow rate. At the same time, the inverted triangular structure makes it difficult for impurities to adhere to the surface of the tank, and they will be discharged along with the cutting fluid when it flows, reducing residue and reducing cleaning difficulty.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The radiator vacuum suction cup clamping device described in this utility model uses a hydraulic cylinder to drive a linkage rod to move a slider within a groove.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 4 As shown, this utility model discloses a vacuum suction cup clamping device for a radiator, comprising a processing table 1; the surface of the processing table 1 is provided with multiple sliding grooves 11; a slider 12 is slidably connected to the middle of the sliding groove 11; a linkage rod 13 is rotatably connected to the middle of the slider 12; a hydraulic cylinder 14 is provided below the processing table 1; an installation ring 15 is fixedly connected to the output end of the hydraulic cylinder 14; the installation ring 15 is rotatably connected to the end of the linkage rod 13; a pipe 16 passes through the middle of the slider 12; a suction cup 17 is fixedly connected to the top of the pipe 16; during operation, the bottom of the pipe 16 is connected to a vacuum pump, the bottom of the hydraulic cylinder 14 is fixedly connected to the ground, and the output end of the hydraulic cylinder 14 is controlled to extend and retract, and the installation ring 15... Pushing the linkage rod 13 causes the slider 12 to slide in the middle of the slide groove 11. Adjusting the distance between multiple suction cups 17 adapts to radiator plates of different sizes. Placing the radiator plate on top of the suction cups 17, starting the vacuum pump creates negative pressure between the suction cups 17 and the plate for adsorption. Then, it is processed. The linkage rod 13 is driven by the hydraulic cylinder 14 to move the slider 12 in the slide groove 11. The distance between multiple suction cups 17 can be flexibly adjusted to adapt to radiator plates of different sizes, reducing changeover time and cost, and increasing clamping versatility. At the same time, the suction cups 17 are connected to the vacuum pump through the pipe 16, using negative pressure to tightly adsorb the radiator plate, reducing plate deformation caused by uneven clamping force and increasing processing accuracy.

[0027] Reference Figure 1 and Figure 5 As shown, a protective plate 2 is fixedly connected to the top of the processing table 1; a movable plate 21 is hinged to the top of the processing table 1; multiple buckles 22 are fixedly connected to one side of the movable plate 21; a slot 23 is opened on one side of the protective plate 2; a stop post 24 is fixedly connected to the middle of the slot 23; during operation, when processing the radiator plate, the movable plate 21 is flipped so that the buckles 22 are inserted into the slot 23. When a set of buckles 22 contacts the stop post 24, the buckles 22 elastically deform towards both sides of the stop post 24, and the stop post 24 locks a set of buckles 22 for fixation. The movable plate 21 can be quickly flipped through the hinged setting. With the buckles 22 inserted into the slot 23 and fixed by the stop post 24, a closed or semi-closed protective area can be formed on the top of the processing table 1, reducing the splashing of debris, coolant or scrap material generated during processing and increasing operational safety.

[0028] Reference Figures 1 to 2As shown, a set of elastic cloth 3 is fixedly connected to the middle of the slide groove 11; the elastic cloth 3 is fixedly connected to the end of the slider 12; during operation, when processing the radiator plate, the set of elastic cloth 3 fills the gap between the slider 12 and the slide groove 11, reducing the entry of cutting fluid into the slide groove 11. By tightly filling the gap between the slide groove 11 and the slider 12 with elastic cloth 3, a barrier is formed, reducing the intrusion of cutting fluid and debris, reducing the wear and corrosion of internal components, reducing the frequency and cost of equipment maintenance, and increasing the life of the slider 12. Cutting fluid seeping into the gap will cause uneven sliding resistance of the slider 12, resulting in jamming or displacement, thus increasing the processing quality.

[0029] Reference Figures 3 to 4 As shown, a damping telescopic rod 4 is fixedly connected to the top of the output end of the hydraulic cylinder 14; the damping telescopic rod 4 is set between the hydraulic cylinder 14 and the processing table 1; during operation, when the output end of the hydraulic cylinder 14 extends or retracts, the end of the damping telescopic rod 4 retracts to absorb the impact force generated by the output end of the hydraulic cylinder 14, reducing the collision between the output end of the hydraulic cylinder 14 and the top of the processing table 1. By setting the damping telescopic rod 4 at the top of the output end of the hydraulic cylinder 14, it can retract itself to absorb the impact force, reduce the direct collision between the hydraulic cylinder 14 and the processing table 1, reduce the wear or deformation of components such as the hydraulic cylinder 14 and the mounting ring 15, and at the same time reduce the workpiece displacement caused by vibration of the processing table 1, increasing the stability of the connection structure.

[0030] Reference Figures 1 to 2 As shown, a sealing lip 5 is fixedly attached to the top of the suction cup 17; the sealing lip 5 is annular; during operation, the sealing lip 5 contacts the bottom of the heat sink plate, and forms a sealing barrier with the bottom of the plate by its own elastic deformation, reducing gas leakage or external impurities from entering the suction cup 17. By setting the sealing lip 5 on the suction cup 17, the gap between the suction cup 17 and the heat sink plate can be filled, reducing the risk of the suction cup 17 losing negative pressure due to gas leakage, weakening the suction force, or even causing the workpiece to fall off, increasing the suction force of the suction cup 17, and improving the stability of the workpiece fixation.

[0031] As shown in the figure, a water outlet groove 6 is provided on the surface of the processing table 1; a water outlet nozzle 61 is fixedly connected to one side of the processing table 1; the water outlet nozzle 61 and the water outlet groove 6 are connected; during operation, a water tank is set below the water outlet nozzle 61. When processing the heat sink plate, the cutting fluid used will collect in the middle of the water outlet groove 6, flow out from the water outlet nozzle 61, and return to the water tank for recycling. By collecting the cutting fluid scattered during the processing through the water outlet groove 6 and returning it to the water tank through the water outlet nozzle 61 for recycling, the frequency of cutting fluid replenishment can be reduced, the cost of consumable procurement can be reduced, and the risk of pollution to the external environment can be reduced, keeping the surface of the processing table 1 clean.

[0032] As shown in the figure, there are multiple suction cups 17. By setting multiple suction cups 17, the adsorption force can be dispersed, and different areas of the bottom of the heat sink can be covered by multiple points of contact, so that the workpiece is subjected to uniform force and closely adheres to the adsorption surface, reducing the risk of displacement caused by insufficient adsorption at a single point and increasing the processing accuracy.

[0033] As shown in the figure, the water outlet 6 is triangular in shape. The inverted triangular shape of the water outlet 6 can guide the cutting fluid to gather towards the center of the bottom of the tank by using the inclined surface, reducing the residence time in the tank and reducing local liquid accumulation caused by slow flow rate. At the same time, the inverted triangular structure makes it difficult for impurities to adhere to the inner surface of the tank. They will be discharged along with the cutting fluid when it flows, reducing residue and reducing cleaning difficulty.

[0034] Working principle: The bottom of pipe 16 is connected to the vacuum pump, and the bottom of hydraulic cylinder 14 is fixed to the ground. The output end of hydraulic cylinder 14 is controlled to extend and retract. The mounting ring 15 pushes the linkage rod 13 to make the slider 12 slide in the middle of the slide groove 11. The distance between multiple suction cups 17 is adjusted to accommodate radiator plates of different sizes. The radiator plate is placed on top of the suction cups 17, and the vacuum pump is started to create negative pressure adsorption between the suction cups 17 and the plate. Then, it is processed. When processing the radiator plate, the movable plate 21 is flipped so that the buckle 22 is inserted into the slot 23. When a set of buckles 22 contacts the stop post 24, the buckles 22 elastically deform to both sides of the stop post 24, and the stop post 24 locks a set of buckles 22 for fixation. During the processing of the radiator plate, a set of elastic cloth 3 fills the gap between the slider 12 and the slide groove 11 to reduce the entry of cutting fluid into the slide groove 11. When the output end of the hydraulic cylinder 14 extends and retracts, the end of the damping telescopic rod 4 retracts to absorb the impact force generated by the output end of the hydraulic cylinder 14 and reduce the collision between the output end of the hydraulic cylinder 14 and the top of the processing table 1. The sealing lip 5 contacts the bottom of the radiator plate and forms a sealing barrier with the bottom of the plate by its own elastic deformation, reducing gas leakage or external impurities entering the suction cup 17. A water tank is set below the water outlet 61. When processing the radiator plate, the cutting fluid used will gather in the middle of the water outlet groove 6, flow out from the water outlet 61, and return to the water tank for recycling.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
