Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing and welding, and in particular to a rapid positioning welding device for aluminum profile processing and a use method thereof. Background Art

[0002] In modern industry and construction, aluminum profiles are widely used due to their light weight, high strength, good corrosion resistance and machinability. However, in order to build more complex structures and meet specific usage requirements, medium and long aluminum profiles are usually connected. Traditional aluminum profile connection methods include bolt connection and riveting. Bolts usually increase the weight and cost of the structure and are prone to loosening after long-term use; riveting can easily damage the surface of the aluminum profile, affecting its appearance and corrosion resistance.

[0003] With the continuous development of welding technology, welding, as an efficient, strong and structural integrity-maintaining connection method, has gradually been applied to the connection of aluminum profiles.

[0004] Since aluminum reacts easily with oxygen in the air, it will quickly form a dense oxide film with a high melting point. This oxide film will hinder the fusion of the filler metal and the base metal, causing defects such as slag inclusion and lack of fusion in the weld, which will have a serious impact on the welding quality. In view of this, aluminum profiles usually need to be welded in a welding chamber when welding;

[0005] The airflow in the aluminum profile welding chamber needs to be relatively stable. Currently, before welding two sections of medium-long aluminum profiles, they need to be butted outside the welding chamber before being transported to the chamber for welding. Since the size of the medium-long aluminum profiles is relatively long, the ends are prone to unstable butt joint during transportation. In order to ensure the accuracy of welding, after the butt joint outside the chamber and transportation are completed, the butt joint effect must be observed, which is not only cumbersome and time-consuming, but also affects the welding efficiency of the aluminum profiles to a certain extent.

[0006] In view of this, we propose a rapid positioning welding device for aluminum profile processing and a method of using the same. Summary of the invention

[0007] The object of the present invention is to provide a rapid positioning welding device for aluminum profile processing and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned object, one of the objects of the present invention is to provide a rapid positioning welding device for aluminum profile processing, comprising a welding box body, the welding box body is supported by a bottom frame, one end of the welding box body is connected to a feeding platform, the feeding platform and the welding box body are separated by an outer baffle plate, a welding bin is formed between the outer baffle plate and the welding box body, a welding head support is installed on the top of the inner cavity of the welding bin, and a welding rod head for welding the aluminum profile body is installed on the welding head support near the middle of the welding bin;

[0012] As a further improvement of the technical solution, the docking mechanism includes an adjustment groove opened inside the welding box, and the adjustment groove is located at the bottom of the welding bin, and two groups of conical gear groups are rotatably arranged inside the adjustment groove, and the two conical gear groups are symmetrically installed, and the two conical gear groups are connected by a connecting shaft, and the end of one of the conical gear groups is connected to an extension shaft;

[0013] The tops of the two conical gear groups are fixedly connected with rotating rods, the two rotating rods are in a folded state, and the other ends of the two rotating rods are located inside the welding bin, the ends of the two rotating rods away from the conical gear groups are movably connected with movable rods, and the other ends of the two movable rods are respectively connected to the bottoms of the two placing plates, and the ends of the two placing plates are connected with side end limit assemblies, which can cause the placing plates to be in a horizontal state during the conveying process.

[0014] As a further improvement of the technical solution, the side end limit assembly includes two slide grooves opened on the inner wall of the welding bin, both of the slide grooves extend to the side wall of the feeding platform, and telescopic rod groups are slidably provided inside the two slide grooves, and both of the telescopic rod groups are composed of an inner rod and an outer rod, and one end of the inner rod away from the outer rod is clamped and slid on the inner wall of the slide groove, and the side of the outer rod away from the inner rod is fixedly connected to the surface of the placement plate;

[0015] Two grooves are provided at the bottom of one end of the two placement plates close to the shrinkage cavity, and a connecting block is slidably provided inside the groove. One end of the connecting block extending out of the groove is fixedly connected to the bonding plate, and the ends of the adjacent bonding plates are in a bonding state.

[0017] As a further improvement of the technical solution, one end of the two placement plates close to the shrinkage cavity is fixedly connected to a side pad, and the two side pads are made of elastic material.

[0018] As a further improvement of the present technical solution, the outer baffle includes a slide of a fixed plate, the fixed plate is connected to the inner wall of the welding box, one end of the slide slides inside the fixed plate, the lower end outer wall of the slide is provided with an inclined corner, and a sweeping strip is fixedly connected to the bottom of the slide.

[0019] The second object of the present invention is to provide a method for operating the above-mentioned rapid positioning welding device for aluminum profile processing, comprising the following method steps:

[0020] S1. First, place two aluminum profile bodies that need to be welded together in the two placement plates at the top of the feeding platform, and fit two sides of the aluminum profile bodies with the inner wall of the placement bin and the surface of the positioning clamping assembly;

[0021] S2. Then, the motor is started to drive the extension shaft fixedly connected to the output shaft of the motor to rotate, thereby driving one of the conical gear sets to rotate. Since the two conical gear sets are connected via a connecting shaft, the two rotating rods connected to the top ends of the two conical gear sets will start in opposite directions at the same speed.

[0022] S3. When the two rotating rods drive the two placing plates from the upper end of the feeding platform into the welding chamber, the two aluminum profile bodies are pushed and squeezed by each other to drive the positioning clamping assembly to clamp and fix the aluminum profile body, and at the same time, the two placing plates are maintained at an angle with the help of the telescopic rod group;

[0023] S4. When the two rotating rods drive the placing plates to rotate to the maximum, the two placing plates are located at the bottom of the welding head support. At this time, the ends of the two placing plates are fitted together, and the aluminum profile bodies located inside the two placing plates are also fitted together, so that the aluminum profile bodies can be quickly positioned and docked during the transportation process;

[0024] S5. Then the welding rod head is used to weld the joints of the two aluminum profile bodies. After welding, the two placement plates are transported out of the welding bin by the docking mechanism again. During the transportation process, the two placement plates slide and separate, which will apply thrust to the welded aluminum profile body, so that the aluminum profile body can also be used to detect the welding effect when it is output.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the quick positioning welding device for aluminum profile processing and the use method thereof, an outer baffle is arranged between the welding box and the feeding platform, so that a space environment with relatively stable airflow is constructed in the welding chamber, which can reduce the interference of external airflow on the inside of the welding chamber, create more stable conditions for welding work, and thus ensure the welding quality and effect;

[0027] 2. In the quick positioning welding device for aluminum profile processing and the use method thereof, the placing mechanism located at the top of the feeding platform can be used to store two aluminum profile bodies that need to be welded. At the same time, combined with the docking mechanism arranged at the bottom of the inner cavity of the welding bin, the placing mechanism with the aluminum profile body placed can be transported to the welding bin for welding. During the transportation process, the ends of the two aluminum profile bodies are butted and fitted, and the positioning and clamping components located inside the placing mechanism are squeezed. When the placing mechanism slides to the bottom of the welding rod head, the two aluminum profile bodies are in a state of stable placement and the ends are fitted, thereby achieving the effect of quickly positioning and clamping the two aluminum profile bodies;

[0028] 3. In the quick positioning welding device for aluminum profile processing and the use method thereof, when the placing mechanism is driven by the docking mechanism to be transported into the welding chamber, it will pass through the bottom end of the outer baffle during transportation, thereby driving the outer baffle to retract. In the process of the placing mechanism passing through the bottom of the outer baffle, the outer baffle can scrape and clean the aluminum profile body inside the placing mechanism. After the welding work is completed, when the placing mechanism relies on the docking mechanism to output the aluminum profile to the outside again, it will pass through the bottom of the outer baffle again. At this time, the outer baffle can clean the surface after welding, further ensuring the surface quality and cleanliness of the aluminum profile.

[0029] 4. In the rapid positioning welding device for aluminum profile processing and its use method, after the two aluminum profiles are welded through the welding rod head, when the docking mechanism drives the placing mechanism to transport the aluminum profile out of the welding bin, along with the movement of the placing mechanism, an outward pulling force will be applied to the aluminum profile inside the placing mechanism, thereby enabling auxiliary detection of the effectiveness of the welding of the aluminum profile body.

[0048] Example 1

[0049] See also Figure 1 and Figure 4As shown, the purpose of this embodiment is to provide a fast positioning welding device for aluminum profile processing, including a welding box 1, the welding box 1 is supported by a base frame 11, one end of the welding box 1 is connected to a feeding platform 13, the feeding platform 13 and the welding box 1 are separated by an outer baffle 14, a welding bin 12 is formed between the outer baffle 14 and the welding box 1, a welding head support 15 is installed on the top of the inner cavity of the welding bin 12, and a welding rod head 16 for welding the aluminum profile body 10 is installed on the welding head support 15 near the middle of the welding bin 12, and a placing mechanism 2 is arranged on the upper end of the feeding platform 13, and the placing mechanism 2 can place the two The welding bin 12 is provided with a docking mechanism 3 at the bottom of the inner cavity, and one end of the docking mechanism 3 extends out of the welding bin 12 and is movably connected with the bottom of the placing mechanism 2. The docking mechanism 3 can drive the placing mechanism 2 to slide into the welding bin 12. The placing mechanism 2 includes a positioning and clamping assembly 20 located therein. When the docking mechanism 3 drives the placing mechanism 2 to slide into the welding bin 12, the positioning and clamping assembly 20 can quickly clamp and position the two aluminum profile bodies 10 that need to be welded. At the same time, the placing mechanism 2 can also assist the two aluminum profile bodies 10 to perform end-to-end butt-jointing.

[0050] The working principle of the welding rod head 16 is as follows: the welding position and conditions are determined by a preset program or sensor, and the control system starts the welding power supply to provide appropriate current and voltage, so that the welding head generates a high-temperature arc to melt the material locally, and at the same time, a protective gas is sprayed to prevent oxidation and impurities.

[0051] When two aluminum profile bodies 10 need to be welded, they need to be stored. In view of this, the specific structure of the placing mechanism 2 is disclosed in combination with the above content. The placing mechanism 2 includes two placing plates 22. The two placing plates 22 are located above the feeding platform 13. Placement bins 25 are provided inside the two placing plates 22. A shrinkage cavity 24 is formed between the two placing plates 22. A docking port 23 is provided on one side of the two placing plates 22 close to the shrinkage cavity 24. The positioning clamping assembly 20 is located at the end of the placing bin 25 away from the docking port 23.

[0052] Combination Figure 2 and Figure 4 As shown, the starting positions of the two placing plates 22 are located above the feeding platform 13, and a shrinkage cavity 24 is formed between the two placing plates 22. The aluminum profile body 10 is in a strip shape, and the two aluminum profile bodies 10 that need to be welded are respectively placed in the placing bins 25 in the two placing plates 22. When the medium and long aluminum profile body 10 is placed inside the placing plate 22, its end can extend out of the docking port 23, so as to achieve the effect of supporting the two aluminum profiles.

[0053] When the two aluminum profile bodies 10 are placed inside the placement bin 25, the two aluminum profile bodies 10 are located at the top of the feeding platform 13. When the two aluminum profile bodies 10 are welded, the two aluminum profile bodies 10 need to be transported to the inside of the welding bin 12. Therefore, the specific structure of the docking mechanism 3 is disclosed in combination with the above structure. The docking mechanism 3 includes an adjustment groove 31 opened inside the welding box 1, and the adjustment groove 31 is located at the bottom of the welding bin 12. Two groups of conical gear groups 32 are rotatably provided inside the adjustment groove 31. The two conical gear groups 32 are symmetrically installed. The two conical gear groups 32 are connected by a connecting shaft 33, and the end of one of the conical gear groups 32 is connected to an extension shaft 36.

[0054] The tops of the two conical tooth groups 32 are fixedly connected with rotating rods 34, the two rotating rods 34 are in a folded state, and the other ends of the two rotating rods 34 are located inside the welding bin 12, and the ends of the two rotating rods 34 away from the conical tooth groups 32 are movably connected with movable rods 35, and the other ends of the two movable rods 35 are respectively connected to the bottoms of the two placing plates 22, and the ends of the two placing plates 22 are connected with side end limit assemblies 30, which can cause the placing plates 22 to be in a horizontal state during the conveying process.

[0055] See also Figure 3 , Figure 4 Combined with Figure 7 After the two aluminum profile bodies 10 are placed, the motor is started to drive the extension shaft 36 fixedly connected to the output shaft of the motor to rotate, thereby driving one of the conical gear sets 32 to rotate in the adjustment groove 31. Since the two conical gear sets 32 are connected by the connecting shaft 33, when one of the conical gear sets 32 rotates, the other conical gear set 32 ​​can be driven to rotate synchronously, so that the two rotating rods 34 can rotate synchronously in the opposite direction, driving the two placement plates 22 to slide synchronously into the welding chamber 12;

[0056] It should be disclosed that: the conical tooth group 32 is composed of two conical teeth meshing and connected. The tooth shape and arrangement of the two conical tooth groups 32 are the same. The two conical tooth groups 32 are connected by a connecting shaft 33. When the two conical tooth groups 32 rotate synchronously, the two rotating rods 34 can be driven to rotate in the opposite direction. This is because one conical tooth group 32 rotates in a specific direction when subjected to a driving force, and through the transmission of the connecting shaft 33, the other conical tooth group 32 will produce an opposite rotation direction due to the matching tooth shape and connection relationship, thereby realizing the reverse rotation of the two conical tooth groups 32, so that the two rotating rods 34 can rotate synchronously in the opposite direction, driving the two placing plates 22 to slide in the opposite direction and fit together.

[0057] Since the conical gear set 32 ​​drives the rotating rod 34 to rotate and adjust the position, and the end of the rotating rod 34 away from the conical gear set 32 ​​is movably connected to the placement plate 22 through the movable rod 35, when the rotating rod 34 is started, it is easy to drive the placement plate 22 to change its angle, thereby affecting the positioning of the aluminum profile body 10. Therefore, in combination with the above structure, the side end limit assembly 30 is disclosed, and the side end limit assembly 30 includes two slide grooves 302 opened on the inner wall of the welding bin 12, and the two slide grooves 302 both extend to the side wall of the feeding platform 13, and the inside of the two slide grooves 302 is slidably provided with a telescopic rod set 301, and the two telescopic rod sets 301 are composed of an inner rod 3011 and an outer rod 3012. The end of the inner rod 3011 away from the outer rod 3012 is clamped and slid on the inner wall of the slide groove 302, and the side of the outer rod 3012 away from the inner rod 3011 is fixedly connected to the surface of the placement plate 22;

[0058] Two grooves 304 are provided at the bottom of one end of the two placement plates 22 close to the shrinkage cavity 24. A connecting block 305 is slidably provided inside the groove 304. One end of the connecting block 305 extends out of the groove 304 and is fixedly connected to the bonding plate 303. The ends of adjacent bonding plates 303 are in a bonding state.

[0059] according to Figure 4 , Figure 6 and Figure 8 As shown, the end of the placement plate 22 away from the docking port 23 is fixedly connected with an outer rod 3012, and the inner rod 3011 is provided for sliding inside the outer rod 3012, and the side of the inner rod 3011 away from the outer rod 3012 is snap-fitted and slid in the slide groove 302 opened on the inner wall of the welding bin 12. When the placement plate 22 slides toward the inside of the welding bin 12 driven by the docking mechanism 3, it can drive the telescopic rod group 301 to slide synchronously. Since the telescopic rod group 301 is composed of the inner rod 3011 and the outer rod 3012, and the inner rod 3011 and the outer rod 3012 can only slide linearly, the placement plate 22 moves linearly during the movement, and the opening angle of the docking port 23 does not change.

[0060] On the contrary, when the placing plate 22 slides toward the feeding platform 13 , the telescopic rod group 301 can still assist the placing plate 22 to achieve a uniform angle.

[0061] After the two aluminum profile bodies 10 are placed in the two placement bins 25 respectively, the placement plate 22 can be driven by the docking mechanism 3 to enter the interior of the welding bin 12. Taking into account the stability of the two aluminum profile bodies 10 in the placement bin 25, in view of this, the specific structure of the positioning and clamping assembly 20 is disclosed in combination with the above structure. The positioning and clamping assembly 20 includes a push plate 201 sliding in the placement bin 25, and the push plate 201 divides the placement bin 25 into a temporary storage groove 206 and an extrusion bin 207. The extrusion bin 207 is equipped with an elastic member 205 and an extrusion bag 204. The inner wall of one side of the temporary storage groove 206 is fixedly connected with a side bag 202. The side bag 202 and the extrusion bag 204 are installed on the same side, and the side bag 202 and the extrusion bag 204 are connected by a connecting pipe 203.

[0062] See also Figure 2 and Figure 5 The inside of the placement bin 25 is equipped with a push plate 201 through an elastic member 205. When the aluminum profile body 10 is placed, two sides of the aluminum profile body 10 are fitted with the push plate 201 and the side away from the side bag 202. The end of the aluminum profile body 10 away from the push plate 201 extends out of the docking port 23. With the reverse rotation of the two rotating rods 34, the two placement plates 22 are driven to rotate in the reverse direction into the welding bin 12. Since the two placement plates 22 have the same initial state and rotate in the opposite direction at the same speed, the two placement plates 22 will get closer and closer, driving the two The ends of the aluminum profile body 10 are fitted together and close to each other. When the two placing plates 22 are close to each other, the shrinkage cavity 24 is reduced. The two aluminum profile bodies 10 push each other, so that the push plate 201 slides toward the extrusion bin 207 to squeeze the extrusion bag 204. The gas in the extrusion bag 204 can be transmitted to the inside of the side bag 202 through the connecting pipe 203. The side bag 202 approaches the aluminum profile body 10. At this time, three sides of the aluminum profile body 10 are clamped, and the other side is fitted with another aluminum profile body 10, achieving the effect of clamping and docking the aluminum profile body 10.

[0063] The aluminum profile body 10 is first bonded at both ends, and then positioned and docked during the transportation process. This method is faster and more efficient than the current common operation process of first docking one end and then fixing it before transportation. It can save time and processes, reduce operating steps, improve production efficiency, and reduce the risk of errors and mistakes caused by step-by-step operations, thereby optimizing the transportation and docking process of the aluminum profile as a whole.

[0064] After the two aluminum profile bodies 10 are welded, the two aluminum profile bodies 10 are combined into one. At this time, the motor is started in reverse to make the two rotating rods 34 rotate at the same speed in the direction of the feeding platform 13. In this process, the two originally fitted placement plates 22 will slide apart. During the sliding period, a thrust will be applied to the welded aluminum profile body 10. If the welding effect of the aluminum profile body 10 is good, the aluminum profile body 10 can overcome the clamping force it is subjected to, so that the two placement plates 22 slide on the surface of the aluminum profile body 10, driving the middle part of the aluminum profile body 10 to be located in the contraction cavity 24, and the push plate 201 fitted at the end of the aluminum profile body 10 will slide toward the docking port 23 due to the loss of driving force, thereby driving the extrusion bag 204 to stretch and pumping the gas in the side bag 202. When the placement plate 22 returns to the top of the feeding platform 13, the welded aluminum profile body 10 is no longer clamped around it, and it can be taken out quickly and easily. If the welding effect of the aluminum profile body 10 is not good, the thrust applied to the aluminum profile body 10 will cause the aluminum profile body 10 to break when the placement plate 22 slides out of the welding chamber 12. It can be seen that while the welded aluminum profile body 10 is output, the welding strength of the aluminum profile body 10 can also be tested.

[0065] When the two placing plates 22 are moved to the bottom of the welding rod head 16 with the help of the docking mechanism 3, the ends of the two placing plates 22 are in contact with each other. In view of the fact that the direct contact and friction between the two placing plates 22 are likely to cause damage to their ends, in order to reduce the damage caused by the contact and friction between the two placing plates 22, the two placing plates 22 are fixedly connected to one end close to the shrinkage cavity 24 with a side pad 21, and both side pads 21 are made of elastic material.

[0066] The improvements are: See Figure 8 As shown, a side pad 21 is fixedly connected to the outer wall of one end of the placement plate 22 close to the contraction cavity 24. The side pad 21 is preferably made of elastic rubber material, so that when the two placement plates 22 are moved to an aligned state with the welding rod head 16, the two side pads 21 can replace the placement plates 22 for fitting, effectively reducing the friction caused by the direct fitting of the two placement plates 22.

[0067] Considering that the two placing plates 22 will pass through the bottom end of the outer baffle plate 14 when sliding from the feeding platform 13 to the interior of the welding bin 12, and when entering the interior of the welding bin 12, the outer baffle plate 14 needs to be pushed open. Therefore, in order to further enhance the pushing effect of the outer baffle plate 14, the outer baffle plate 14 includes a slide 142 of a fixed plate 141, the fixed plate 141 is connected to the inner wall of the welding box 1, one end of the slide 142 slides inside the fixed plate 141, the lower end outer wall of the slide 142 is provided with an inclined corner 4, and the bottom of the slide 142 is fixedly connected with a sweeping strip 143.

[0068] The improvement lies in: combining Figure 7 As shown, the fixed plate 141 and the slide 142 connected thereto by the spring member can separate the welding bin 12 from the feeding platform 13. When the placing plate 22 slides into the welding bin 12, as the placing plate 22 slides, the slide 142 can be pushed to retract into the fixed plate 141. At the same time, the surface of the aluminum profile body 10 located inside the placing plate 22 can be swept with the help of the sweeping strip 143 installed at the bottom of the slide 142. On the contrary, when the welded aluminum profile body 10 passes through the outer baffle plate 14 again, the slide 142 is pushed back into the fixed plate 141 again. The sweeping strip 143 can clean the surface of the welded aluminum profile, further ensuring the surface quality and cleanliness of the aluminum profile. When the placing plate 22 is away from the outer baffle plate 14, the slide 142 loses its driving force and is driven to the original position with the help of the spring member.

[0069] Among them, the outer wall of the lower end of the slide 142 is provided with an inclined corner 4, which can assist the placement plate 22 or the aluminum profile body 10 to facilitate the pushing of the slide 142, thereby improving the storage effect of the aluminum profile body 10. A circulation hole is opened in the middle of the slide 142, which does not affect the airflow inside the welding bin 12 and is convenient for the staff to check the welding process.

[0070] It should be noted that the total length of the welded aluminum profile body 10 in this application needs to be slightly smaller than the total length of the two placement chambers 25 added together.

[0071] Example 2

[0072] This embodiment is based on the content provided in Embodiment 1, and aims to provide a method for using a rapid positioning welding device for aluminum profile processing, and the specific steps are as follows:

[0073] S1. First, place two aluminum profile bodies 10 to be welded together in the two placement plates 22 at the top of the feeding platform 13, and fit two sides of the aluminum profile body 10 with the inner wall of the placement bin 25 and the surface of the positioning clamping assembly 20;

[0074] S2. Then, the motor is started to drive the extension shaft 36 fixedly connected to the output shaft of the motor to rotate, thereby driving one of the conical gear sets 32 to rotate. Since the two conical gear sets 32 are connected via the connecting shaft 33, the two rotating rods 34 connected to the top ends of the two conical gear sets 32 will start in the same speed and in opposite directions.

[0075] S3. When the two rotating rods 34 drive the two placing plates 22 from the upper end of the feeding platform 13 into the welding chamber 12, the two aluminum profile bodies 10 are pushed and squeezed by each other, driving the positioning clamping assembly 20 to clamp and fix the aluminum profile body 10, and at the same time, the two placing plates 22 are maintained at an angle by means of the telescopic rod group 301;

[0076] S4. When the two rotating rods 34 drive the placing plates 22 to rotate to the maximum, the two placing plates 22 are located at the bottom of the welding head support 15. At this time, the ends of the two placing plates 22 are in contact with each other, and the aluminum profile body 10 located inside the two placing plates 22 is also in contact with each other, so that the aluminum profile body 10 can be quickly positioned and docked during the transportation process;

[0077] S5. Then, the welding rod head 16 is used to weld the fitting parts of the two aluminum profile bodies 10. After welding, the docking mechanism 3 is used again to transport the two placement plates 22 out of the welding bin 12. During the transportation process, the two placement plates 22 slide and separate, which will apply thrust to the welded aluminum profile body 10, so that the aluminum profile body 10 can also be used to detect the welding effect when it is output.

[0078] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
