Description

Technical Field

[0001] The invention belongs to the field of welding equipment, and in particular relates to automobile welding equipment for reducing thermal attenuation of a vehicle body. Background Art

[0002] Welding, also known as fusion or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. The use of welding equipment provides convenience for the connection between workpieces.

[0003] In the existing body welding process, long-term welding often leads to unstable welding power, resulting in excessively high temperature at the welding site. When heat accumulates at the welding site, the molecular microstructure of the welded product material changes and the composition segregates, leading to thermal attenuation of the product. The occurrence of thermal attenuation during welding will reduce the welding strength, reduce the weld quality, and be accompanied by some welding defects. Summary of the invention

[0004] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides an automobile welding device which can reduce the thermal decay of the vehicle body.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: an automobile welding equipment for reducing thermal attenuation of a vehicle body, comprising a main body, a guide assembly arranged on the main body, a welding assembly and a pressing plate slidably arranged on the main body, the guide assembly is slidably provided with a support plate, and the pressing plate can slide toward the support plate, and is characterized in that the main body is also fixedly connected with an air guide plate located below the welding assembly and evenly distributed along the sliding direction of the support plate, the main body is provided with a water cooling pipe embedded in the air guide plate, the main body is also fixedly connected with an air intake plate, the air intake plate is provided with an air intake duct, and the air intake plate is provided with an air outlet nozzle connected to the air intake duct, the air guide plate has an air guide wall on the side close to the air intake plate, the air guide wall is an arc wall recessed toward the inside of the air guide plate, and the air outlet direction of the air outlet nozzle is toward the air guide wall.

[0006] When in use, the support plate is slidably arranged on the guide assembly, so the support plate is moved out of the interior of the main body by sliding the support plate, so that the product to be welded is placed on the support plate, and the product to be welded is brought into the main body by the sliding support plate. Since the pressing plate is slidably arranged on the main body, after the product is brought into the main body by the support plate, the product is clamped between the pressing plate and the support plate by the pressing plate, and then the welding work is completed by the welding assembly. Since a plurality of air guide plates are fixedly connected to the main body, and the air guide plates are located below the welding assembly, and since an air intake plate is also fixedly connected to the main body, the air flow is passed through the air intake pipe, and the air flow is blown out through the air outlet nozzle. Since the air outlet direction of the air outlet nozzle is toward the air guide wall of the air guide plate, specifically, the air guide wall is an arc wall that is concave toward the air guide plate, the air flow blown from the air outlet nozzle is blown on the arc wall, so that the air flow is guided upward, so that the air flow is blown onto the product and the welding assembly, so that the welding temperature of the product and the welding assembly during the welding process is reduced. Moreover, since the main body is also provided with a water cooling pipe embedded in the air guide plate, the water cooling pipe can be passed through the air outlet nozzle. The setting of the water-cooling pipe ensures that the airflow blown out from the air outlet nozzle will exchange heat with the water-cooled plate after it blows onto the air guide wall, thereby first reducing the temperature of the airflow. When the airflow is guided by the air guide wall to the welding product and welding assembly, the temperature difference between the gas and the welding product and welding assembly is increased, thereby further achieving rapid cooling. At the same time, the airflow is evenly distributed along the sliding direction of the support plate through the air guide plate, thereby expanding the area of ​​the air guide plate guiding the airflow, so that the airflow is more comprehensively and evenly guided toward the temperature of the welding product and welding assembly, thereby avoiding the phenomenon of thermal attenuation that is easy to occur after long-term welding of the welding product and welding assembly.

[0007] In the above-mentioned automobile welding equipment for reducing thermal attenuation of vehicle body, a mounting groove for embedding water cooling pipe is provided on one side wall of the air guide plate away from the air guide wall, and the mounting groove is provided along the peripheral curve of the side wall of the air guide plate.

[0008] By setting the installation groove, the cold water pipe is embedded in the air guide plate, so that the position of the cold water pipe is fixed. Since the installation groove is opened along the surrounding curve of the side wall of the air guide plate, specifically in the shape of the upper half of the "convex" character, the water-cooling pipe is fixed more stably and the cooling of the cold water pipe is maximized, thereby maximizing the temperature difference between the air guide plate and the outside world, thereby further allowing the airflow to pass through the air guide plate to blow to the welding products and welding components for rapid cooling.

[0009] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, the air guide plates are staggeredly distributed in a direction from an air guide plate close to an air intake plate to a direction away from the air intake plate.

[0010] By staggeredly distributing the air guide plates in a direction from an air guide plate close to an air inlet plate to an air guide plate away from the air inlet plate, the distribution area of ​​the air guide plates is further expanded, thereby further expanding the cooling area of ​​the welding products and welding components blown by the guided airflow, thereby more comprehensively reducing the temperature of the welding products and welding components, and preventing thermal attenuation from occurring easily.

[0011] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, the guide assembly includes a sliding rod fixedly connected to a main body and a limiting buckle buckled on one end of the sliding rod and fixedly connected to the main body, and a sliding groove matching with the sliding rod is provided on the support plate, the sliding groove is roughly in an inverted "U" shape, and the sliding rod has a limiting portion at one end away from the limiting buckle.

[0012] Through the inverted "U"-shaped slide groove and the matching slide rod, the radial and circumferential directions of the support plate are limited, so that the support plate can stably achieve axial sliding on the slide rod, and then through the setting of the limiting part and the limiting buckle, when the support plate slides between the limiting part and the limiting buckle, the axial sliding of the support plate can be limited by abutting against the limiting part or the limiting buckle.

[0013] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, a plurality of slots are provided on a side wall of the support plate facing the pressing plate, and shock absorbing blocks inserted into the slots are provided on the support plate.

[0014] By setting up a shock-absorbing block and a plurality of slots, specifically, the shock-absorbing block is made of rubber material, so that after the welding product is placed on the shock-absorbing block of the pallet and clamped by the pressure plate, the welding product is more stable during the welding process, and the shock-absorbing block can be adjusted to be inserted into different slots according to the size of welding products of different sizes, thereby adjusting the position of the shock-absorbing block on the pallet to match welding products of different sizes.

[0015] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, a handle is provided on one side wall of the support plate.

[0016] The setting of the handle makes it easier to drag the pallet during work.

[0017] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, a telescopic rod capable of extending toward the support plate is provided on the main body, and one end of the telescopic rod close to the support plate is fixedly connected to the pressing plate.

[0018] Specifically, the pressing plate and the supporting plate can clamp the welding product on the supporting plate by extending and retracting the telescopic rod.

[0019] In the above-mentioned automobile welding equipment for reducing thermal attenuation of the vehicle body, the cross-section of the support plate along the sliding direction of the pressing plate is "L"-shaped, and a clearance cavity is formed between the support plate and the main body, and the air intake plate is located in the clearance cavity.

[0020] By setting the concession cavity, the installation positions of the air intake plate and the support plate on the main body are made more compact, thereby further expanding the cooling area, thereby improving the cooling efficiency and avoiding thermal attenuation.

[0021] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, the welding assembly includes a bracket rod fixedly connected to the main body, a sliding rod slidably arranged on the bracket rod, and a welding gun head slidably arranged on the sliding rod, the bracket rod is provided with a threaded rod 1 that passes through one end of the sliding rod, a driving motor 1 connected to the threaded rod 1 is fixedly connected on one side of the bracket rod, and a sliding groove for inserting the other end of the sliding rod is provided on the bracket rod, the sliding rod includes a sliding portion, a sliding block connected to one end of the sliding portion and inserted into the sliding groove and matched with the sliding groove, and a matching portion connected to the other end of the sliding portion and penetrated by the threaded rod 1 and matched with the threaded rod 1, a threaded rod 2 is provided on the sliding portion of the sliding rod, a helical gear 1 is fixedly connected to one end of the threaded rod 2, and a helical gear 2 meshing with the helical gear 1 is also provided on the sliding portion, a driving motor 2 connected to the helical gear 2 is provided on one side of the sliding rod, and the welding gun head has a connecting portion that is penetrated by the threaded rod 2 and matched with the threaded rod 2.

[0022] Specifically, the threaded rod 1 is driven to rotate by the driving motor 1. Since the sliding rod has a matching portion that matches the threaded rod 1, after the threaded rod 1 rotates, the reciprocating sliding movement of the sliding rod can be realized, thereby driving the welding gun head to realize reciprocating sliding in this direction together. Since the sliding portion of the sliding rod is provided with a threaded rod 2, and one end of the threaded rod 2 is fixedly connected with a bevel gear 1, the sliding portion is also provided with a bevel gear 2 that meshes with the bevel gear 1, and one side of the sliding rod is provided with a driving motor 2 connected with the bevel gear 2, therefore, by driving the driving motor 2, the bevel gear 2 is driven to rotate, the bevel gear 2 drives the bevel gear 1 to rotate, and the bevel gear 1 drives the threaded rod 2 to rotate. At the same time, since the welding gun head has a connecting portion that is penetrated by the threaded rod 2 and matches with the threaded rod 2, when the threaded rod 2 rotates, the reciprocating sliding movement of the welding gun head on the sliding rod can be realized, thereby driving the driving motor 1 and the driving motor 2 respectively, so that the welding gun head can realize horizontal and longitudinal sliding on the main body, thereby meeting the welding work at different positions of the welding product.

[0023] In the above-mentioned automobile welding equipment for reducing thermal attenuation of a vehicle body, the bracket rod has a yield portion on one side along the sliding direction of the sliding rod and close to the second driving motor, and a yield space is formed below the yield portion for the second driving motor to pass through.

[0024] By setting the让位部 (retaining part), the interference between the driving motor two and the support rod during the sliding process of the sliding rod is avoided, thereby expanding the sliding space of the sliding rod and greatly improving the applicability of the automotive welding equipment for reducing the heat attenuation of the vehicle body.

[0025] Compared with the prior art, the automotive welding equipment for reducing the heat attenuation of the vehicle body has the following advantages:

[0026] 1. Through the setting of the water-cooled pipe, after the air flow blown out from the air outlet nozzle blows onto the air guide wall, it will exchange heat with the water-cooled plate, first reducing the temperature of the air flow. When the air flow is diverted by the air guide wall to the welding product and the welding assembly, the temperature difference between the gas and the welding product and the welding assembly is increased to further achieve rapid cooling.

[0027] 2. Through the diffusion distribution of the air guide plate, the area for guiding the air flow by the air guide plate is expanded, enabling more comprehensive and uniform guidance of the air flow towards the temperature of the welding product and the welding assembly, thereby avoiding the phenomenon of heat attenuation that is likely to occur after the welding product and the welding assembly are welded for a long time.

[0028] 3. Through the setting of the installation groove in the shape of the upper half of a "convex" character, while making the water-cooled pipe more stable, the cooling of the cold water pipe is maximized, thereby maximizing the temperature difference between the air guide plate and the outside world, and further enabling the air flow to be blown onto the welding product and the welding assembly through the air guide plate for rapid cooling.

[0029] By setting the让位腔 (retaining cavity), the installation positions of the air inlet plate and the support plate on the main body are made more compact, thereby further expanding the cooling area, improving the cooling efficiency, and avoiding heat attenuation.

Since the air outlet direction of the air outlet nozzle 8 is toward the air guide wall 9a of the air guide plate 9, specifically, the air guide wall 9a is an arc wall recessed into the air guide plate 9, the air flow blown out from the air outlet nozzle 8 is blown on the arc wall, so that the air flow is guided upward, so that the air flow is blown onto the product and the welding assembly 3, thereby reducing the welding temperature of the product and the welding assembly 3 during the welding process, and since the main body 1 is also provided with a water cooling pipe 10 embedded in the air guide plate 9, specifically, the water cooling pipe 10 has an inlet The water inlet and the water outlet, the water inlet are connected to the water supply equipment, and the water outlet is connected to the water tank.

Through the setting of the water cooling pipe 10, the air flow blown out from the air outlet nozzle 8 will be blown onto the air guide wall 9a, and will exchange heat with the water cooling plate, first reducing the temperature of the air flow. When the air flow is guided to the welding product and the welding component 3 by the air guide wall 9a, the temperature difference between the gas and the welding product and the welding component 3 is increased to further achieve rapid cooling. At the same time, the air guide plate 9 is evenly distributed along the sliding direction of the support plate 5, which expands the area of ​​the air guide plate 9 to guide the air flow, so that the air flow is more comprehensively and evenly guided toward the temperature of the welding product and the welding component 3, thereby avoiding the phenomenon of thermal attenuation that is easy to occur after the welding product and the welding component 3 are welded for a long time.
