Description

Technical Field

[0001] This utility model relates to the field of welding torch holder technology, specifically a welding torch holder for welding robots. Background Technology

[0002] In modern industrial production, welding robots are widely used in various fields due to their efficient and stable welding performance. As a key component of welding robots, the performance of the welding torch holder directly affects the positioning accuracy, welding stability, and welding quality of the welding torch. The main function of the welding torch holder is to securely mount the welding torch on the robot arm and to enable precise adjustment of the welding torch position and angle according to welding requirements.

[0003] A search revealed a patent, CN219561923U, which discloses a welding torch holder for a welding robot. The holder includes a base, a fixing device, and a welding torch body. An adjustment device is mounted above the base, and the fixing device is mounted above the adjustment device. The welding torch body is installed inside the fixing device. The adjustment device includes a bearing, a telescopic cylinder, and a telescopic rod. A bearing is mounted on the left side above the base, and the telescopic cylinder is mounted above the bearing. A telescopic rod is installed inside the telescopic cylinder, and a first rotating shaft is mounted above the telescopic rod. The first rotating shaft is connected to the fixing device. A connecting rod is mounted on the right side of the outer wall of the telescopic cylinder, and a support rod is mounted on the right side of the connecting rod. A second rotating shaft is mounted above the support rod. This invention facilitates adjustment of the welding nozzle height and welding orientation to meet different welding needs and improves the applicability of the device.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents use mounting brackets and bolts to limit and fix the welding torch of the welding robot, and a telescopic rod to adjust the welding angle of the welding torch. However, in reality, when using welding robots for welding, the welding areas that need to be welded are quite extensive. The aforementioned comparative documents use a telescopic rod to adjust the angle of the welding torch in one direction, which reduces the welding range of the welding torch. Therefore, there is an urgent need in the art to improve the welding torch fixing bracket to overcome the shortcomings of the prior art. Utility Model Content

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1-7 A welding torch holder for a welding robot includes a connecting frame 1 for connecting to the welding robot and a welding torch head 8 for welding. A rotating plate 2 is rotatably connected to the side of the connecting frame 1 away from the welding robot. A fixing seat 3 is fixedly installed on the side of the rotating plate 2 away from the connecting frame 1. A rotatable rotating ball 4 is embedded in the side of the fixing seat 3 away from the rotating plate 2. A rotating groove 5 adapted to the rotating ball 4 is provided on one side of the fixing seat 3. A portion of the rotating ball 4 protrudes from the rotating groove 5, and two symmetrical first fixing plates 6 are fixedly installed on its side. The welding torch head 8 is located between the two first fixing plates 6. A telescopic device 7 with a telescopic effect is rotatably connected between the first fixing plates 6 and the rotating plate 2. A drive mechanism for driving the rotating plate 2 to rotate is provided on one side of the connecting frame 1. The drive motor 9 is provided on one side of the connecting frame 1, and a controller 10 for controlling the drive motor 9 and the telescopic device 7 is provided on one side of the connecting frame 1. A ring gear 11 is fixedly installed on the side of the rotating plate 2 and snapped onto the side of the connecting frame 1. A gear 12 that meshes with the ring gear 11 is fixedly installed on the output end of the drive motor 9. A first adjusting threaded rod 13 is threaded through and threadedly connected to the first fixed plate 6. A first clamping block 14 that is adapted to the welding gun head 8 is rotatably connected to the end of the first adjusting threaded rod 13. A first limiting nut 15 is threadedly connected to the side of the first adjusting threaded rod 13. A welding wire 16 is provided at one end of the welding gun head 8. A first wiring port 17 adapted to the welding wire 16 is opened on the rotating plate 2, the fixed seat 3, the rotating ball 4 and the connecting frame 1. An anti-slip pad 25 is provided on one side of the first clamping block 14.

[0032] The specific implementation method in this embodiment: The welding gun head 8 is a prior art technology, mainly used for welding. The connecting frame 1 is connected and installed to the end of a welding robot arm using existing fasteners. When installing the welding gun head 8, the fixed position of the welding gun head 8 is placed between two first clamping blocks 14. By rotating the two first adjusting threaded rods 13, which are threadedly connected to the first fixing plate 6, the rotation of the first adjusting threaded rods 13 drives the first clamping blocks 14 to move. The two first clamping blocks 14 clamp and fix the welding gun head 8, and the anti-slip pad 25 on one side of the first clamping block 14 provides an anti-slip effect, improving the stability after clamping and fixing the welding gun head 8. Then, the first limiting nut 15 is tightened to limit and fix the position of the first adjusting threaded rod 13. When welding is required, it is used in conjunction with existing welding... The robot arm moves to weld the workpiece via the welding torch head 8. If the welding angle of the welding torch head 8 needs to be adjusted during the welding process, the telescopic device 7 is activated. The telescopic end of the telescopic device 7 drives the first fixed plate 6 to shift. The first fixed plate 6 drives the rotating ball 4 to rotate in the rotating groove 5. The two ends of the telescopic device 7 are respectively rotatably connected to the sides of the rotating plate 2 and the first fixed plate 6. In conjunction with the activation of the drive motor 9, the output end of the drive motor 9 drives the gear 12 to rotate. When the gear 12 rotates, it drives the ring gear 11 to rotate. The ring gear 11 drives the rotating plate 2 to rotate, thus completing the adjustment of the welding torch head 8 at various angles and improving the welding range of the welding torch head 8. The first wiring port 17 is used for the wiring of the welding wire 16. It is worth noting that the aforementioned drive motor 9 is a forward and reverse motor, which can prevent the welding wire 16 or other connecting wires from getting tangled during the rotation of the rotating plate 2.

[0033] Example 2

[0034] Please see Figures 1-3 and Figure 7 This embodiment includes the above embodiment, and further includes: a movable plate 18 is provided above the rotating plate 2, and a second cable routing port 24 adapted to the first cable routing port 17 is provided through the movable plate 18. A plurality of elastic members 19 are provided between the movable plate 18 and the rotating plate 2. A positioning unit for positioning the welding wire 16 is provided on one side of the movable plate 18 and the inner top wall of the connecting frame 1. The positioning unit includes a plurality of second fixing plates 20 respectively installed on one side of the movable plate 18 and the inner top wall of the connecting frame 1. A second adjusting threaded rod 21 is threaded through and threadedly connected to the second fixing plate 20. A second clamping block 22 adapted to the welding wire 16 is rotatably connected to one end of the second adjusting threaded rod 21. A second limiting nut 23 is threadedly connected to the side of the second adjusting threaded rod 21. A plurality of guide rods 26 penetrating the movable plate 18 are fixedly installed on the upper part of the rotating plate 2. The elastic members 19 are sleeved on the side of the guide rods 26.

[0035] In this embodiment, the welding torch head 8 rotates, causing the welding wire 16 to move. The rotating sphere 4 is a non-perfect sphere, which, in conjunction with the first wiring port 17 and the second wiring port 24, provides clearance for the welding wire 16. By rotating the second adjusting threaded rod 21, the second clamping block 22 moves, and the two second clamping blocks 22 position and clamp the welding wire 16. Then, the second limiting nut 23 is tightened to limit and fix the position of the second adjusting threaded rod 21. In addition, the welding wire 16 between the positioning unit on the inner top wall of the connecting frame 1 and the positioning unit on the moving plate 18 has a reserved length for movement. When the welding torch head 8 deflects, it will pull the welding wire 16 downward, and the moving plate 18 will move accordingly. The movable plate 18 slides along the sides of several guide rods 26, compressing the elastic element 19, which is specifically a spring. The guide rods 26 limit the movable plate 18 and prevent radial deformation of the elastic element 19. When the welding torch head 8 returns to a perpendicular position to the rotating plate 2, the elastic force of the elastic element 19 pushes the movable plate 18 upward, and the welding wire 16 located in the first wiring port 17 moves upward accordingly, preventing the section of the welding wire 16 located in the first wiring port 17 from getting tangled. If the welding wire 16 gets tangled in the first wiring port 17, the rotating ball 4 will not be able to rotate. It is worth noting that the elastic element 19 is selected with a spring with an appropriate elastic coefficient according to the actual situation, ensuring that it will not cause damage to the welding torch head 8 and the welding wire 16.
