Technical Field

[0001] This utility model belongs to the field of double-layer plate resistance welding positioning technology, specifically an automated welding device. Background Technology

[0002] Automotive double-layer heat insulation panels are structural components used for heat insulation and sound insulation in automobiles. They are usually composed of two layers of plates of different materials or thicknesses. Their main functions include heat insulation, sound insulation, and protection of components. Common double-layer heat insulation panel materials include aluminum alloys and aluminum foil composite materials, which are lightweight, have good heat insulation performance, and strong reflectivity.

[0003] In conventional double-layer plate welding positioning fixtures, the positioning mechanism is usually fixed on the base and cannot be moved. This results in the inability to flexibly install and position plates of different specifications and sizes for production. The disassembly and assembly of the mechanism requires manual intervention after production stops, which consumes a lot of production time and personnel working time, resulting in low production efficiency and ineffective quality assurance. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an automated welding device that can adapt to double-layer plates of different specifications. This utility model solves the problem of inability to achieve flexible installation and positioning in production with plates of different sizes, as well as the low efficiency, high risk of errors, and high production quality assurance risks associated with manual disassembly and installation. It also improves the adaptability of the device to upper-layer plate materials of different sizes and adds precise positioning and clamping structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated welding device, including a worktable, a first set of servo components fixedly mounted on the top surface of the worktable, the first set of servo components including a fixed frame, and the fixed frame being fixedly connected to the worktable, a servo motor fixedly mounted on the outer side of the right side of the fixed frame, a forward threaded shaft fixedly mounted at the end of the main shaft of the servo motor, a reverse threaded shaft fixedly mounted on the other side of the forward threaded shaft, and the reverse threaded shaft being rotatably connected to another fixed frame, a threaded sleeve slidably mounted on the outer side of the reverse threaded shaft, a second sliding frame fixedly mounted on the outer side of the threaded sleeve, another threaded sleeve threadedly connected to the outer side of the forward threaded shaft, and a first sliding frame fixedly mounted on the outer side of the other threaded sleeve.

[0006] Preferably, a second set of servos is fixedly installed on the top surface of the second sliding frame, and multiple support frames are fixedly installed on the top surface of the second set of servos. A double-layer plate body is attached to the top surface of the support frames.

[0007] Preferably, a third set of servos is fixedly installed on the top surface of the first sliding frame, and another support frame is fixedly installed on the top surface of the first sliding frame.

[0008] Preferably, a cylinder is fixedly installed on the outer side of the support frame, and a pressure block is fixedly installed on the top surface of the cylinder, and the pressure block slides inside the support frame.

[0009] Preferably, a balance shaft is provided through the interior of the pressure block, and the balance shaft is fixedly connected to the support frame.

[0010] Preferably, a fixed shaft is slidably arranged inside the support frame, and a spring is sleeved on the outside of the fixed shaft. One side of the spring is fixedly connected to the support frame, and a flat plate is fixedly arranged on the other side of the spring. The flat plate is fixedly connected to the fixed shaft. It is difficult to straighten the double-layer plate body when it is placed manually.

[0012] Preferably, the bottom surface of the workbench is fixedly provided with multiple support legs, and multiple rectangular holes are opened on the outer side of the support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a servo motor to drive the forward threaded shaft and the reverse threaded shaft to rotate. The reverse threaded shaft drives multiple threaded sleeves on the outside to move. The two threaded sleeves drive the first sliding frame and the second sliding frame to move respectively, thereby driving the second set of servo motors and the third set of servo motors at the top to move. The second set of servo motors and the third set of servo motors operate in the same way as the first set of servo motors. In this way, the positioning structure of the device can be adjusted according to the size of the double-layer plate material, so as to achieve more accurate positioning. At the same time, a clamping structure is added to ensure that the problem of inaccurate welding point position is avoided.

[0015] 2. This utility model uses multiple flat plates inside the support frame to straighten the double-layer plate body. Since it is difficult to straighten the double-layer plate body manually, if the support frame is moved to straighten it, it is easy to crush it if the force is not controlled properly. By placing the double-layer plate body in the middle of the flat plate, the flat plate is pushed by the spring on the outside of the fixed shaft, which can naturally straighten the double-layer plate body.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5As shown, this utility model provides an automated welding device, including a workbench 1. A first set of servo components 2 is fixedly mounted on the top surface of the workbench 1. The first set of servo components 2 includes a fixed frame 201, which is fixedly connected to the workbench 1. A servo motor 202 is fixedly mounted on the outer side of the right fixed frame 201. A forward threaded shaft 203 is fixedly mounted at the end of the spindle of the servo motor 202. A reverse threaded shaft 204 is fixedly mounted on the other side of the forward threaded shaft 203 and is rotatably connected to another fixed frame 201. A threaded sleeve 205 is slidably mounted on the outer side of the reverse threaded shaft 204. A second sliding bracket 207 is fixedly installed on the side. Another threaded sleeve 205 is threadedly connected to the outer side of the forward threaded shaft 203. A first sliding bracket 206 is fixedly installed on the outer side of the other threaded sleeve 205. The forward threaded shaft 203 and the reverse threaded shaft 204 are driven to rotate by the servo motor 202. The reverse threaded shaft 204 drives the multiple outer threaded sleeves 205 to move. The two threaded sleeves 205 respectively drive the first sliding bracket 206 and the second sliding bracket 207 to move. In this way, the positioning structure of the device can be adjusted according to the size of the double-layer plate material, so as to achieve more accurate positioning and avoid the problem of inaccurate welding point position.

[0026] Specifically, a second set of servo 5 is fixedly installed on the top surface of the second sliding frame 207, and multiple support frames 7 are fixedly installed on the top surface of the second set of servo 5. The double-layer plate body 14 is attached to the top surface of the support frame 7. The support frame 7 is used to place the double-layer plate body 14 and support it.

[0027] Furthermore, a third set of servo 6 is fixedly installed on the top surface of the first sliding frame 206, and another support frame 7 is fixedly installed on the top surface of the first sliding frame 206. The distance between the third set of servo 6 and the top support frame 7 of the second set of servo 5 is adjusted by the first set of servo components 2. The second set of servo 5 and the third set of servo 6 then run, thereby adjusting the distance between their top support frames 7.

[0028] Furthermore, a cylinder 8 is fixedly installed on the outer side of the support frame 7, and a pressure block 9 is fixedly installed on the top surface of the cylinder 8. The pressure block 9 slides inside the support frame 7, and the double-layer plate body 14 can be pressed and fixed by the pressure block 9.

[0029] It is worth noting that a balance shaft 10 is installed through the inside of the pressure block 9, and the balance shaft 10 is fixedly connected to the support frame 7. The balance shaft 10 can ensure the balance of the pressure block 9 when it moves.

[0030] It is worth noting that a fixed shaft 12 is slidably installed inside the support frame 7, and a spring 13 is sleeved on the outside of the fixed shaft 12. One side of the spring 13 is fixedly connected to the support frame 7, and a flat plate 11 is fixedly installed on the other side of the spring 13. The flat plate 11 is also fixedly connected to the fixed shaft 12. Since it is difficult to straighten the double-layer plate body 14 when it is manually placed, if the support frame 7 is moved to straighten it, it is easy to crush it if the force is not properly controlled. By placing the double-layer plate body 14 in the middle of the flat plate 11, the flat plate 11 is pushed by the spring 13 on the outside of the fixed shaft 12, which can naturally straighten the double-layer plate body 14.

[0031] It is worth mentioning that a slide rail 3 is fixedly installed on the top surface of the fixed frame 201, and a slider 4 is slidably installed on the outer side of the slide rail 3. The slider 4 is fixedly connected to the second sliding frame 207. The structure of the first sliding frame 206 is the same. The slide rail 3 and the slider 4 can increase the smoothness of sliding.

[0032] It is worth emphasizing that the bottom surface of the workbench 1 is fixedly equipped with multiple support feet 15, and multiple rectangular holes are opened on the outer side of the support feet 15. The entire device can be fixed to the ground through the support feet 15 to maintain its stability.

[0033] Among them, the servo motor 203 and the air top 8 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0034] Working principle:

[0035] When using the automated welding device, firstly, the workbench 1 is fixed to the ground using support feet 15. Then, according to the length of the length and width adjustment device of the double-layer plate body 14, the length is first adjusted using the first set of servo components 2 on the top surface of the workbench 1. The servo motor 202 on the outside of the fixing frame 201 is turned on. The servo motor 202 drives the forward threaded shaft 203 and the reverse threaded shaft 204 to rotate. The reverse threaded shaft 204 drives multiple threaded sleeves 205 on the outside to move. The two threaded sleeves 205 respectively drive the first sliding frame 206 and the second sliding frame 207 to move, thereby driving the second set of servo 5 and the third set of servo 6 on the top to move. The slide rail 3 and the slider 4 can increase the smoothness of its movement. Then, the length of the support frame 7 on the top surface of the third set of servo 6 and the second set of servo 5 is adjusted. Its operating structure is the same as that of the first set of servo components 2. Then, the double-layer plate is... The main body 14 is placed on the top surface of the support frame 7. Then, the switch of the cylinder 8 is turned on, and the cylinder 8 drives the pressure block 9 to move, thereby fixing the double-layer plate main body 14. The balance shaft 10 can increase the balance when the pressure block 9 moves. Since it is difficult to straighten the double-layer plate main body 14 manually, if the support frame 7 is moved to straighten it, it is easy to crush it if the force is not controlled properly. The double-layer plate main body 14 is placed in the middle of the flat plate 11. The flat plate 11 is pushed by the spring 13 on the outside of the fixed shaft 12, which can naturally straighten the double-layer plate main body 14. This utility model solves the problem of not being able to achieve flexible installation and positioning production when facing plates of different specifications and sizes, as well as the low efficiency of manual disassembly and installation, the easy to install incorrectly, and the high risk of production quality assurance. At the same time, it improves the adaptability of the device to upper plate materials of different sizes and adds a precise positioning and pressing structure.
