Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, and in particular to a welding device with flaw detection function. Background Technology

[0002] In the field of welding robot technology, welding devices with flaw detection capabilities refer to equipment that integrates welding operations with flaw detection. They utilize welding robots to perform the welding operation and flaw detection sensors to monitor the welded areas in real time, ensuring welding quality. Such devices are widely used in aerospace, automotive manufacturing, and other fields with high welding precision requirements, enabling integrated welding and quality inspection operations.

[0003] However, in practical use, existing welding devices with flaw detection functions have some shortcomings:

[0004] On the one hand, the flaw detection sensors of traditional devices lack effective protective structures and are easily affected by factors such as spattered weld slag and high temperature during the welding process, which can lead to damage to the flaw detection sensors or a decrease in detection accuracy.

[0005] On the other hand, the large amount of fumes generated during the welding process cannot be discharged in time, which not only pollutes the working environment, but may also affect the detection effect of the flaw detection sensor and the working accuracy of the welding head. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a welding device with flaw detection function, which overcomes the shortcomings of the prior art and effectively solves the problem of lack of effective protective structure and inability to discharge fumes in a timely manner.

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

[0008] A welding device with flaw detection function includes a mounting frame. A welding robot is mounted on the top outer wall of the mounting frame, and a connecting seat is provided on the outer wall of one end of the welding robot. A welding head is installed through the inner wall of the connecting seat, and a mounting plate is fixedly connected to the outer wall of the welding head. A protective frame is welded to one side of the outer wall of the mounting plate, and a flaw detection sensor is fixedly connected to the inner wall of the protective frame by screws. A protective plate is hinged to one side of the outer wall of the protective frame, and a cylinder is hinged between the protective plate and the protective frame.

[0009] A smoking pipe is provided on one side of the protective frame, and a smoking tube is fixedly connected to the outer wall of one end of the smoking pipe.

[0010] Preferably, the welding robot includes a single-axis motor fixedly connected to the top outer wall of the mounting frame by screws, a dual-axis motor mounted on the output shaft of the single-axis motor, and a first arm mounted on the output shaft of the dual-axis motor.

[0011] Preferably, the welding robot further includes a three-axis motor mounted on the outer wall of one end of the first arm, a four-axis motor mounted on the outer wall of the three-axis motor, a second arm mounted on the outer wall of the four-axis motor, and a five-axis motor mounted on the outer wall of one side of the second arm, with the connecting seat fixedly connected to the output shaft of the five-axis motor.

[0012] Preferably, a baffle is welded to one outer wall of the mounting plate.

[0013] Preferably, a fixing sleeve is fixedly connected to the outer wall of the smoking tube, and a connecting column is welded between the fixing sleeve and the mounting plate.

[0014] Preferably, a support platform is welded to the top outer wall of the mounting bracket, and a PLC controller is fixedly connected to the top outer wall of the support platform by screws.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The welding device with flaw detection function designed in this paper has a protective structure consisting of a mounting plate, a protective frame, a protective plate and a cylinder. When welding is performed, the cylinder drives the protective plate to open, exposing the flaw detection sensor for detection. After welding is completed, the protective plate closes, which can effectively prevent the damage of welding slag and high temperature to the flaw detection sensor. This solves the problem of lack of protection and easy damage of the flaw detection sensor in traditional devices, and ensures the accuracy of flaw detection and the service life of the sensor.

[0017] 2. The welding device with flaw detection function designed in this paper utilizes a fume treatment system consisting of a fume extraction bucket, a fume extraction pipe, a fixing sleeve, and a connecting column. The fume extraction bucket collects fumes near the welding area and discharges them through the fume extraction pipe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: A welding device with flaw detection function includes a mounting frame 1. A welding robot 2 is mounted on the top outer wall of the mounting frame 1. A connecting seat 3 is provided on the outer wall of one end of the welding robot 2. A welding head 4 is installed through the inner wall of the connecting seat 3. A mounting plate 5 is fixedly connected to the outer wall of the welding head 4. A protective frame 6 is welded to one side of the outer wall of the mounting plate 5. A flaw detection sensor 7 is fixedly connected to the inner wall of the protective frame 6 by screws. A protective plate 8 is hinged to one side of the outer wall of the protective frame 6. A cylinder 9 is hinged between the protective plate 8 and the protective frame 6.

[0025] The welding robot 2 is mounted on top of the mounting frame 1. The spatial position of the welding head 4 and the flaw detection sensor 7 is adjusted by the movement of the multi-axis motor and the arm. The connecting seat 3 is used to install the welding head 4. The welding head 4 performs welding operations. The mounting plate 5 is used to install components such as the protective frame 6. The flaw detection sensor 7 is fixed inside the protective frame 6 with screws to provide installation space for the sensor. The protective plate 8 is hinged to one side of the protective frame 6 and is driven to open and close by the cylinder 9 to protect the flaw detection sensor 7.

[0026] In this embodiment, a protective structure consisting of mounting plate 5, protective frame 6, protective plate 8 and cylinder 9 is provided. When welding is performed, cylinder 9 drives protective plate 8 to unfold, exposing flaw detection sensor 7 for detection. After welding is completed, protective plate 8 is closed, which can effectively block welding slag splash and high temperature from damaging flaw detection sensor 7. This solves the problem of lack of protection and easy damage to flaw detection sensor 7 in traditional devices, and ensures the accuracy of flaw detection and the service life of sensor.

[0027] In the second embodiment, a smoking pipe 10 is provided on one side of the protective frame 6, and a smoking pipe 11 is fixedly connected to the outer wall of one end of the smoking pipe 10. A fixing sleeve 13 is fixedly connected to the outer wall of the smoking pipe 11, and a connecting column 14 is welded between the fixing sleeve 13 and the mounting plate 5.

[0028] The smoking pipe 10 is used to collect the smoke and dust generated during the welding process. The smoking pipe 11 is connected to the smoking pipe 10 to discharge the smoke and dust. The fixing sleeve 13 is fixed to the outer wall of the smoking pipe 11 and welded to the mounting plate 5 through the connecting column 14 to ensure the installation stability of the smoking pipe 11.

[0029] In this embodiment, a fume treatment system consisting of a fume hood 10, a fume pipe 11, a fixing sleeve 13, and a connecting column 14 is used. The fume hood 10 collects fumes near the welding area and discharges them through the fume pipe 11. The fixing sleeve 13 and the connecting column 14 ensure the stable installation of the fume pipe 11. This solves the problem that fumes cannot be discharged in time in traditional devices, improves the working environment, and avoids interference from fumes on flaw detection and welding operations.

[0030] The welding robot 2 includes a single-axis motor 21 fixedly connected to the top outer wall of the mounting frame 1 by screws, a dual-axis motor 22 mounted on the output shaft of the single-axis motor 21, and a first arm 23 mounted on the output shaft of the dual-axis motor 22. The welding robot 2 also includes a three-axis motor 24 mounted on the outer wall of one end of the first arm 23, a four-axis motor 25 mounted on the outer wall of the three-axis motor 24, a second arm 26 mounted on the outer wall of the four-axis motor 25, and a five-axis motor 27 mounted on the outer wall of one side of the second arm 26. The connecting seat 3 is fixedly connected to the output shaft of the five-axis motor 27.

[0031] Multi-axis motors, such as single-axis motor 21 and dual-axis motor 22, work together to drive the first boom 23 and the second boom 26 to move, thereby enabling multi-angle adjustment of the welding head 4.

[0032] A baffle 12 is welded to one side of the outer wall of the mounting plate 5.

[0033] The baffle 12 is used to block welding slag splashes and protect the mounting plate 5 and surrounding components.

[0034] A support platform 15 is welded to the top outer wall of the mounting bracket 1, and a PLC controller 16 is fixedly connected to the top outer wall of the support platform 15 by screws.

[0035] The PLC controller 16 is used to control the operation of the entire device and realize the automated control of processes such as welding, flaw detection, and fume treatment.

[0036] Working principle: When in use, the PLC controller 16 starts the welding robot 2, and the single-axis motor 21, dual-axis motor 22 and other multi-axis motors work together to drive the first arm 23 and the second arm 26 to move the welding head 4 and the protective frame 6 to the position to be welded.

[0037] Welding head 4 begins welding, and simultaneously, cylinder 9 drives protective plate 8 to unfold, exposing flaw detection sensor 7. Flaw detection sensor 7 monitors the welding area in real time and feeds the data back to PLC controller 16. Fumes generated during welding are collected by fume hood 10 and discharged through fume hood 11. During welding, cylinder 9 drives protective plate 8 to close, and protective frame 6 and baffle 12 prevent weld spatter from splashing, protecting flaw detection sensor 7 and welding head 4.

[0038] When the welding angle needs to be adjusted, the multi-axis motor drives the boom to move, and the five-axis motor 27 drives the connecting seat 3 to rotate, so as to realize the spatial position and angle adjustment of the welding head 4 and the flaw detection sensor 7 to adapt to the welding and flaw detection needs of different workpieces.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
