Description

Technical Field

[0001] The invention belongs to the technical field of metal plate welding, and in particular relates to a metal plate welding device and a welding method with adjustable welding distance. Background Art

[0002] Metal plate welding is a process of connecting two or more metal plates by melting or pressing. Common metal plate welding methods include: arc welding: using an electric arc to heat the metal, melt the metal and form a weld; gas shielded welding: such as argon arc welding, gas shielded welding, etc., using shielding gas (such as argon) to prevent the weld and molten pool from being oxidized by air; resistance welding: using electric current to generate heat between metal plates to melt them locally, and then pressing them together to form a weld; laser welding: using a laser beam to heat the metal to the melting point to achieve welding; plasma welding: connecting metal plates by plasma arc heating; when choosing a welding method, it is necessary to consider factors such as metal type, plate thickness, connection strength requirements and production efficiency. In addition, the welds between two metal plates of different material thicknesses are also different. Thicker metal plates may require wider welds to ensure sufficient welding strength, while thinner metal plates can use finer welds. Therefore, when welding metal plates, it is necessary to strictly follow the relevant process specifications and operating procedures to ensure that the welding quality meets the requirements.

[0003] The existing method of welding two metal plates is usually manual or mechanical equipment. The former is more flexible in operation, and the staff can weld two metal plates of different thicknesses according to their own skills and estimate the welding distance. However, when welding a large number of metal plates, the efficiency is low and the manual estimation accuracy is not high, resulting in the inability to guarantee the welding quality. The latter uses a robotic arm for welding, which has high accuracy, but can only weld one group of metal plates at a time. When a large number of metal plates need to be welded within a specified time limit, multiple robotic arms are required, resulting in high welding costs. Summary of the invention

[0012] The cam is connected with the second end of the hydraulic cylinder to move the hydraulic cylinder to move upwards, and the cam is connected with the second end of the hydraulic cylinder to move the hydraulic cylinder to move upwards, so that the cam can move upwards and downwards.

[0013] Through the above technical scheme, when taking materials from multiple metal plate bodies, the cylinder is started, and the cylinder piston contracts to drive the movable plate to rise, so that the movable plate pushes multiple limit pins, and with the cooperation of the corresponding limit grooves, it drives the two material taking frames of each group to move toward each other, and move to the specified distance according to the thickness of the metal plate body and the type of material, and then starts the first hydraulic cylinder, so that the first hydraulic cylinder piston pushes the first connecting frame, which drives the entire material taking mechanism to move downward, and then drives the multiple first electromagnets to move downward, so that the multiple first electromagnets are fitted with the top of the corresponding metal plate body and magnetically attracted to the corresponding metal plate body, and then moved to the position just above the fixing mechanism through the material transfer mechanism, so that multiple groups of metal plate bodies can be magnetically attracted at one time, and then multiple groups of metal plate bodies can be welded at one time, and when taking materials, the distance between the two magnetically attracted metal plate bodies is the final weld distance, and no subsequent adjustment is required, and the work efficiency is high.

[0015] Through the above technical solution, when a metal plate body is placed in the fixing mechanism, the second motor is started, and the second motor drives the screw to rotate by rotating the output shaft, thereby driving the nut seat to move, and then driving the fixing mechanism to move. During the movement, the welding mechanism performs welding at the same time, and when it moves to the other end, the welding of multiple metal plate bodies is completed.

[0016] Furthermore, the fixing mechanism includes a first rotating shaft rotatably connected to the center of the second concave frame, the outer wall of the first rotating shaft is provided with a plurality of bidirectional thread grooves, the center of the second concave frame and the two side positions close to the first rotating shaft are fixedly connected with first limiting rods, one end of the first rotating shaft is fixedly connected with a first turntable, the rear end of the outer wall of the first turntable is fixedly connected with a first pointer, the front end of the second concave frame is provided with a first scale, the outer wall of the first rotating shaft is provided with a plurality of groups of evenly distributed first movable seats, the plurality of groups of the first movable seats are respectively threadedly connected with the corresponding bidirectional thread grooves, the plurality of groups of the first movable seats are slidably connected with the two first limiting rods, the tops of the plurality of groups of the first movable seats are fixedly connected with positioning seats, and the tops of the plurality of positioning seats are fixedly installed with two second electromagnets.

[0017] Through the above technical scheme, before welding, the staff calculates the weld between the two metal plate bodies according to the thickness and material type of the metal plate bodies, and rotates the first turntable to drive the first pointer to point to the specified first scale position. The rotation of the first turntable drives the first shaft to rotate, and the rotation of the first shaft drives the multiple groups of first movable seats to move, so that the two first movable seats in each group move toward each other. Since the multiple groups of first movable seats are evenly distributed, the moving distances are also the same. The first scale position finally pointed to by the first pointer is the distance finally adjusted by the multiple groups of positioning seats, and then the weld distance between the two metal plate bodies. Metal plate bodies of different thicknesses and materials can be welded. After welding a batch of metal plate bodies of different specifications, it is only necessary to stop the machine for adjustment, and then the next batch of metal plate bodies of different specifications can be welded. It is not only simple to operate, but also highly functional.

[0018] Furthermore, the welding mechanism includes a mounting bracket fixedly connected to the top center of the support frame, the front and rear ends of one side of the mounting bracket are fixedly connected to a fourth slide rail, a second hydraulic cylinder is fixedly installed at the top center of the mounting bracket, the bottom end of the second hydraulic cylinder piston is fixedly connected to the second connecting bracket, the front and rear ends of one side of the second connecting bracket are fixedly connected to a fifth slide bar, a second rotating shaft is rotatably connected between the front and rear ends of the second connecting bracket, a plurality of external threads are provided on the outer wall of the second rotating shaft, a second limiting rod is fixedly connected to the center of the second connecting bracket and the two sides close to the second rotating shaft, a second turntable is fixedly connected to the front end of the second rotating shaft, a second pointer is fixedly connected to the rear end of the outer wall of the second turntable, a second scale is provided at the front end of the second connecting bracket, a plurality of evenly distributed second movable seats are provided on the outer wall of the second rotating shaft, and a welding gun is fixedly installed on one side of the plurality of second movable seats.

[0019] Through the above technical scheme, according to the thickness of the metal plate body and the type of material, the welding gun needs to be adjusted to the position directly above the weld between the two metal plate bodies. By rotating the second turntable, the second pointer is driven to point to the specified second scale position. The rotation of the second turntable drives the second shaft to rotate, and the rotation of the second shaft drives the multiple second movable seats to move. Since the multiple second movable seats are evenly distributed, the moving distances are also the same, which in turn drives the corresponding welding guns to move. The second scale position finally pointed to by the second pointer is the distance finally adjusted by the multiple welding guns, and then the position directly above the weld between the two metal plate bodies. The staff needs to adjust the position of the welding gun according to the metal plate bodies of different thicknesses and different materials, so as to facilitate precise welding of the metal plate bodies.

[0020] Furthermore, the plurality of second movable seats are respectively threadedly connected to the corresponding external threads, and the plurality of second movable seats are all slidably connected to the second limiting rod.

[0021] Through the above technical solution, when a metal plate body is placed in the fixing mechanism and moves to the bottom of multiple welding guns, the second hydraulic cylinder is started, and the second hydraulic cylinder drives the second connecting frame to move downward through the piston, thereby driving the multiple welding guns to move downward to the specified position. When the fixing mechanism drives the corresponding metal plate body to move, the multiple welding guns weld the corresponding two metal plate bodies. When the fixing mechanism moves to the other end, the welding of the multiple metal plate bodies is completed.

[0022] A welding method of a metal plate welding device with adjustable welding distance, comprising the following specific steps:

[0023] Step 1: The staff places multiple metal plate bodies on one side of the top of the conveying roller assembly, and the conveying roller assembly conveys the multiple metal plate bodies to the other side and fits them with the baffle bar to achieve positioning;

[0024] Step 2: Calculate the weld between the two metal plate bodies according to the thickness and material type of the metal plate bodies, rotate the first turntable, and drive the first pointer to point to the specified first scale position. The rotation of the first turntable drives the first shaft to rotate, and the rotation of the first shaft drives the multiple groups of first movable seats to move, so that the two first movable seats in each group move toward each other. Since the multiple groups of first movable seats are evenly distributed, the moving distance is also the same. The first scale position finally pointed to by the first pointer is the distance finally adjusted by the multiple groups of positioning seats, and then the weld distance between the two metal plate bodies;

[0025] Step 3: According to the thickness of the metal plate body and the type of material, the welding gun needs to be adjusted to the position just above the weld between the two metal plate bodies. The second turntable is rotated to drive the second pointer to point to the specified second scale position. The rotation of the second turntable drives the second shaft to rotate. The rotation of the second shaft drives the multiple second movable seats to move. Since the multiple second movable seats are evenly distributed, the moving distances are also the same, which in turn drives the corresponding welding guns to move. The second scale position finally pointed to by the second pointer is the distance finally adjusted by the multiple welding guns, and then the position just above the weld between the two metal plate bodies.

[0026] Step 4: After adjusting the equipment, start the first motor, the output shaft of the first motor rotates to drive the gear to rotate, so that the gear meshes and rotates on the rack, and under the cooperation of multiple pulleys and corresponding slide rails, the movable frame is driven to move to the upper position of multiple metal plate bodies, and the cylinder is started. The cylinder piston contracts to drive the movable plate to rise, so that the movable plate pushes multiple limit pins, and under the cooperation of the corresponding limit slots, it drives the two material picking racks of each group to move toward each other, and according to the thickness of the metal plate body and the type of material, it moves to the specified distance, and then starts the first hydraulic cylinder, so that the first hydraulic cylinder piston pushes the first connecting rack, which drives the entire material picking mechanism to move downward, and then drives the multiple first electromagnets to move downward, so that the multiple first electromagnets are attached to the top of the corresponding metal plate body, and are magnetically attracted to the corresponding metal plate body, and then move to the position directly above the multiple positioning seats through the material transfer mechanism, and then place the multiple metal plate bodies in the corresponding positioning seats through the material picking mechanism;

[0027] Step 5: When metal plate bodies are placed in multiple positioning seats, start multiple second electromagnets to magnetically fix the corresponding metal plate bodies, and then start the second motor. The second motor drives the screw to rotate through the output shaft, thereby driving the nut seat to move, and then driving the multiple positioning seats to move. At this time, start the second hydraulic cylinder, and the second hydraulic cylinder drives the second connecting frame to move downward through the piston, thereby driving the multiple welding guns to move downward to the specified position. When the multiple positioning seats drive the corresponding metal plate bodies to move, the multiple welding guns weld the corresponding two metal plate bodies;

[0028] Step 6: When the multiple positioning seats are moved to the other end, the welding of the multiple metal plate bodies is completed, and the staff removes the welded metal plate bodies.

[0029] The beneficial effects of the present invention are as follows: (1) The present invention can position and fix metal plate bodies of different thicknesses and materials by designing a fixing mechanism and a welding mechanism, and then weld them. After welding a batch of metal plate bodies of different specifications, it only needs to stop the machine for adjustment, and then the next batch of metal plate bodies of different specifications can be welded. It is not only simple to operate, but also highly functional. (2) The present invention can magnetically attract multiple groups of metal plate bodies at one time by designing a material picking mechanism, and then weld multiple groups of metal plate bodies at one time. The welding efficiency is high. When picking up the materials, the distance between the two metal plate bodies that are magnetically attracted is the final weld distance, and no subsequent adjustment is required, thereby reducing the processing steps and improving work efficiency.

At this time, the second hydraulic cylinder 703 is started. The second hydraulic cylinder 703 drives the second connecting frame 704 to move downward through the piston, and then drives the plurality of welding guns 713 to move downward to the designated position. When the plurality of positioning seats 608 drives the corresponding metal plate bodies 8 to move, the plurality of welding guns 713 weld the corresponding two metal plate bodies 8.
