Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a welding fixture for processing automotive pedals. Background Technology

[0002] In the precision machining process of automobile manufacturing, the welding process for automobile pedals is an extremely critical and meticulous operation. When the automobile pedal is clamped and securely fixed between the fixed claw and the moving claw for subsequent welding processing, a series of complex physical changes quietly occur.

[0003] Once the welding equipment is started, a high-intensity current instantly passes through the welding torch, releasing enormous energy in a very short time. This rapidly melts the welding rod or wire and precisely drips it onto the welding area of ​​the car's pedal. During this process, due to the thermal effect of the current and the intense chemical reaction generated during welding, a large amount of heat inevitably is generated on the surface of the car's pedal. This heat spreads rapidly across the pedal surface like a surging tide, causing the pedal's temperature to rise sharply.

[0004] As welding continues, the surface temperature of the car pedal rises steadily, reaching an extremely high level. At this point, the air around the pedal is warped and deformed by the heat. Due to the excessively high temperature, the metal material of the pedal is in a state of thermal expansion and has not yet cooled and stabilized. If the car pedal is forcibly removed from between the fixed and movable claws immediately after welding, the hot pedal could not only burn the operator's hands, causing serious injury, but also, due to the principle of thermal expansion and contraction, the sudden external force could cause the pedal to deform, affecting its dimensional accuracy and overall quality, or even rendering it unusable, resulting in wasted raw materials and increased production costs.

[0005] More importantly, to avoid the aforementioned risks, operators must wait for the car pedal to cool naturally to a safe temperature before removing it. This waiting process undoubtedly consumes a significant amount of production time, forcing the interruption of welding procedures that could otherwise be carried out efficiently. This significantly reduces the welding efficiency of the car pedal and affects the production schedule and capacity of the entire automotive production line. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a welding fixture for processing automotive pedals, which helps the pedals to cool down quickly after welding.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A welding fixture for automotive pedal processing includes a base, on which a clamping mechanism is provided. The clamping mechanism includes a fixed plate fixedly connected to the base and a telescopic assembly. The movable part of the telescopic assembly is fixedly connected to a movable plate adapted to the fixed plate. The outer walls of the fixed plate and the movable plate are provided with an air-cooling assembly facing the welding point through an angle adjustment assembly. A heat-conducting plate is fixedly provided on the working surface of the fixed plate and the movable plate. Multiple heat dissipation fins that are in direct contact with the outside are evenly arranged around the heat-conducting plate.

[0009] Preferably, the angle adjustment assembly includes a U-shaped adjustment frame, and the inner walls on both sides of the adjustment frame are rotatably connected to the side wall of the air-cooling assembly through damping bearings.

[0010] Preferably, the air-cooling component includes an air-cooling pipe, and a plurality of small air blowers are arranged inside the air-cooling pipe along its length.

[0011] Preferably, the air-cooled pipe is frustum-shaped, the size of the air inlet of the air-cooled pipe is 1.5 to 2 times the size of the air outlet, and the outer wall of the air-cooled pipe is provided with a ceramic fiber heat insulation layer.

[0012] Preferably, the telescopic component is a cylinder.

[0013] Preferably, the heat-conducting plate and the heat sink are made of copper alloy, and the heat sink is designed to be wavy.

[0014] This utility model has the following beneficial effects:

[0015] 1. Air-cooling components are installed facing the welding area to accelerate cooling airflow. In the welding fixture for automotive pedal processing, the outer walls of the fixed plate and the movable plate are equipped with air-cooling components facing the welding area via an angle adjustment assembly. After the pedal is welded, the air-cooling components can directly blow cooling airflow onto the welded area. Because the airflow acts directly on the high-temperature welding area, it can quickly remove the heat generated during welding, thereby effectively accelerating the cooling rate of the pedal after welding, reducing the time required for natural cooling, and improving production efficiency.

[0016] II. Angle Adjustment Component for Flexible Adjustment of Air-Cooling Component Angle to Ensure Cooling Effect: The angle adjustment component includes a U-shaped adjustment bracket, with its inner walls on both sides rotatably connected to the side walls of the air-cooling component via damping bearings. This design allows the angle of the air-cooling component to be flexibly adjusted according to the actual welding position and cooling requirements. When welding pedals of different shapes or positions, operators can easily adjust the air-cooling component to the optimal blowing angle, ensuring that the cooling airflow can accurately act on the welding area, maximizing the cooling effect and further improving the cooling efficiency of the pedal after welding.

[0017] 3. Multiple small air blowers are installed within the air-cooling assembly to enhance the cooling airflow intensity: Multiple small air blowers are installed along the length of the air-cooling pipes in the air-cooling assembly. The simultaneous operation of multiple air blowers generates a more powerful cooling airflow. Compared to a single blower, this design significantly increases the airflow rate and velocity, allowing more cool air to quickly reach the welding area, carrying away more heat and thus more effectively reducing the pedal temperature, accelerating the cooling process, and ensuring that the welded pedal quickly reaches a safe operating temperature.

[0018] IV. Special Shape and Insulation Design of the Air-Cooling Pipe for Optimized Cooling Performance: The air-cooling pipe is frustum-shaped, with the inlet size being 1.5-2 times the outlet size. This special shape design helps to increase airflow pressure and velocity. As airflow enters the air-cooling pipe from the inlet, the airflow is compressed due to the gradually narrowing pipe diameter, resulting in a stronger airflow at the outlet and enhancing the cooling effect. Simultaneously, the outer wall of the air-cooling pipe is equipped with a ceramic fiber insulation layer, which prevents the air-cooling pipe from overheating due to heat generated by the internal fan and the high-temperature external environment during operation. This ensures that the air-cooling pipe maintains a low temperature, thereby guaranteeing a lower temperature of the blown-out airflow and further improving cooling efficiency.

[0019] V. The heat-conducting plate and heat sink work together to rapidly conduct and dissipate welding heat: A heat-conducting plate is fixedly installed on the working surface of both the fixed and movable plates. Multiple heat sinks, which are in direct contact with the outside environment, are evenly distributed around the heat-conducting plate. During welding, the heat-conducting plate rapidly conducts the heat generated during welding from the pedal to itself, while the heat sinks, with their large surface area, fully contact the outside air, quickly dissipating the heat conducted by the heat-conducting plate into the surrounding environment. This combination of heat conduction and dissipation effectively reduces the temperature of the pedal welding area, assisting the air-cooling components to achieve rapid pedal cooling. This ensures that the pedal cools down quickly after welding, reducing the adverse effects of high temperatures on the pedal material properties.

[0020] VI. The heat-conducting plate and heat sink are made of copper alloy and designed in a corrugated shape to improve heat dissipation efficiency: The heat-conducting plate and heat sink are made of copper alloy, which has excellent thermal conductivity, enabling rapid heat transfer from the pedal to the heat sink. Simultaneously, the corrugated shape of the heat sink increases the contact area between the heat sink and the air, allowing heat to dissipate more quickly. Compared to flat heat sinks, corrugated heat sinks provide a larger heat dissipation area in the same space, significantly improving heat dissipation efficiency, further accelerating the cooling speed after pedal welding, and enhancing the overall cooling performance of the welding fixture.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, a welding fixture for processing automotive pedals includes a base 1, on which a clamping mechanism is provided. The clamping mechanism includes a fixed plate 201 fixedly connected to the base 1 and a telescopic component 202. The movable part of the telescopic component 202 is fixedly connected to a movable plate 203 adapted to the fixed plate 201. The outer walls of the fixed plate 201 and the movable plate 203 are provided with air-cooling components facing the welding point through an angle adjustment component. A heat-conducting plate 301 is fixedly provided on the working surface of the fixed plate 201 and the movable plate 203. Multiple heat sinks 302 that are in direct contact with the outside are evenly arranged around the heat-conducting plate 301.

[0027] like Figure 1As shown, the clamping mechanism consists of a fixed plate 201 and a movable plate 203. The fixed plate 201 is fixedly connected to the base 1, and the movable plate 203 is fixedly connected to the movable part of the telescopic assembly 202. Before welding, the movable plate 203 is moved towards the fixed plate 201 by controlling the telescopic assembly 202 (e.g., a cylinder), thereby clamping the car pedal between the fixed plate 201 and the movable plate 203, ensuring the pedal remains stable during welding and preventing shaking from affecting the welding quality. Air-cooling components facing the welding area are installed on the outer walls of the fixed plate 201 and the movable plate 203 via angle adjustment components. After the pedal welding is completed, the air-cooling components are activated (e.g., a small blower 502 inside the air-cooling pipe 501 starts operating), generating a cooling airflow that blows directly onto the welding area. The cooling airflow can quickly remove the large amount of heat generated during welding, reducing the temperature of the welding area and achieving a preliminary rapid cooling effect. Meanwhile, the angle adjustment component (such as the U-shaped adjustment bracket 401 in conjunction with the damping bearing 402) can flexibly adjust the angle of the air-cooling component, enabling it to accurately align with pedals of different shapes and welding positions, ensuring that the cooling airflow always effectively acts on the welding area. A heat-conducting plate 301 is fixedly installed on the working surfaces of the fixed plate 201 and the movable plate 203. Multiple heat sinks 302, which are in direct contact with the outside environment, are evenly distributed around the heat-conducting plate 301. During the welding process, the heat-conducting plate 301 utilizes its excellent thermal conductivity to quickly conduct the heat generated at the pedal welding area to the entire heat-conducting plate 301. Subsequently, the heat sinks 302, with their large surface area, fully contact the outside air, quickly dissipating the heat conducted from the heat-conducting plate 301 into the surrounding environment. This combination of heat conduction and dissipation can continuously reduce the temperature of the pedal welding area, assisting the air-cooling component in completing the pedal cooling process, ensuring that the pedal cools down quickly after welding, reducing the impact of high temperatures on the pedal material properties, and improving welding quality and the finished product quality of the pedal.

[0028] like Figure 1 As shown, the angle adjustment assembly includes a U-shaped adjustment frame 401, with its inner walls on both sides rotatably connected to the side walls of the air-cooling assembly via damping bearings 402. The angle adjustment assembly is composed of a U-shaped adjustment frame 401, with its inner walls on both sides rotatably connected to the side walls of the air-cooling assembly via damping bearings 402. When it is necessary to adjust the blowing angle of the air-cooling assembly, the operator can manually apply external force to rotate the air-cooling assembly around the damping bearings 402. The damping bearings 402 have certain damping characteristics, providing appropriate resistance during the rotation of the air-cooling assembly, allowing the air-cooling assembly to remain stably stationary after rotating to the desired angle, without changing the angle due to slight shaking. In this way, the air-cooling assembly can flexibly adjust the blowing direction according to the welding position and shape of the pedal, ensuring that the cooling airflow can accurately act on the welding area and improve the cooling effect.

[0029] like Figures 1 to 2As shown, the air-cooling assembly includes an air-cooling pipe 501, within which multiple small air blowers 502 are arranged along its length. When the air blowers 502 are activated, the motor drives the fan blades to rotate at high speed, creating airflow within the air-cooling pipe 501. The simultaneous operation of multiple air blowers 502 generates a large flow rate and velocity of cooling airflow. This airflow is directly directed at the welded pedal area, carrying away the heat generated during welding and achieving rapid cooling of the pedal.

[0030] like Figures 1 to 2 As shown, the air-cooled pipe 501 is frustum-shaped, and the inlet size of the air-cooled pipe 501 is 1.5-2 times the outlet size. The outer wall of the air-cooled pipe 501 is equipped with a ceramic fiber insulation layer. The air-cooled pipe 501 is designed in a frustum shape, and the inlet size is 1.5-2 times the outlet size. When airflow enters the air-cooled pipe 501 from the inlet, the pipe diameter gradually decreases, and according to fluid dynamics principles, the airflow is compressed, increasing its velocity. At the outlet, the airflow is ejected at a higher velocity, enhancing the impact of the cooling airflow on the welding area, more effectively removing heat, and improving cooling efficiency. The outer wall of the air-cooled pipe 501 is equipped with a ceramic fiber insulation layer. During the operation of the air-cooled assembly, the internal air blower 502 may generate some heat, and the welding environment may also be affected by high temperatures. The ceramic fiber insulation layer has good thermal insulation performance, which can prevent external heat from being transferred to the interior of the air-cooled pipe 501, and at the same time prevent the heat generated inside the air-cooled pipe 501 due to the operation of the fan from being transferred to the outgoing airflow, ensuring that the temperature of the outgoing airflow is low, thereby ensuring the cooling effect.

[0031] The telescopic component 202 is designed as a cylinder, which is a mature technology and easy to control.

[0032] like Figure 1 As shown, the heat-conducting plate 301 and the heat sink 302 are made of copper alloy, with the heat sink 302 having a wavy shape. Copper alloy has excellent thermal conductivity. During the welding process, a large amount of heat is generated at the pedal welding area. The heat-conducting plate 301 can quickly conduct this heat from the pedal to itself, rapidly reducing the temperature of the pedal welding area and minimizing the impact of high temperatures on the pedal material properties. The wavy shape of the heat sink 302 increases the contact area between the heat sink 302 and the air. After the heat-conducting plate 301 conducts heat to the heat sink 302, the heat sink 302, with its large surface area, fully exchanges heat with the surrounding air, quickly dissipating the heat into the air. The wavy design allows air to flow more smoothly around the heat sink 302, further improving heat dissipation efficiency and assisting the air-cooling components in completing the pedal cooling process.

[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
