Description

Technical Field

[0001] This utility model relates to the technical field of welding torch adjustment devices, specifically a welding torch posture adjustment device for welding robots. Background Technology

[0002] When adjusting the welding torch posture, welding robots need to precisely control the spatial angle, position, and movement trajectory of the torch to ensure welding quality. The welding torch is the part that performs the welding operation during the welding process; it's a tool used for gas welding, shaped like a gun with a nozzle at the front that emits a high-temperature flame as a heat source.

[0003] Therefore, welding robots need to adjust the direction of the welding torch nozzle during the welding process, and a posture adjustment device is required.

This can cause the nozzle to collide with the equipment or the workpiece below when the adjustment device is used, resulting in damage to the nozzle and rendering it unusable. Therefore, a welding robot welding torch attitude adjustment device with a protective structure is proposed. Utility Model Content

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.

[0035] Please see Figures 1-5 This utility model provides a technical solution:

[0036] A welding robot torch posture adjustment device includes:

[0037] The lifting mechanism 3, rotating mechanism 4, and adjusting mechanism 5, used for adjusting the welding angle of the welding torch 6, are respectively located above the worktable 1; and

[0039] By setting clamping blocks 15 on both sides of the welding torch 6, and fixing the clamping blocks 15 to the adjustment mechanism 5 respectively, the welding torch 6 held between the two sets of clamping blocks 15 is driven by the adjustment mechanism 5 to adjust the angle. A protective mechanism 7 is set on the side wall of the clamping blocks 15 to protect the nozzle at the end of the welding torch 6. The nozzle is protected by the protective mechanism 7. A controller is also set on one side of the surface of the workbench 1 to control the welding torch 6, rotary motor 9, first electric telescopic rod 14, electric push rod 17, hydraulic rod 23 and second electric telescopic rod 24 involved in this application. The model can be purchased according to the actual use. The controller controls the lifting mechanism 3, rotating mechanism 4 and adjustment mechanism 5 above to adjust the posture of the welding torch 6, ensuring that the nozzle at the end of the welding torch 6 will not collide with external equipment or the workpiece below under the protection of the protective mechanism 7 during the adjustment process, so as not to cause damage to the welding torch 6.

[0040] Protective mechanism 7 includes:

[0041] A protective cover 18 is used to protect the nozzle at the end of the welding torch 6, and an electric push rod 17 is used to drive the protective cover 18 to extend and retract back and forth. The electric push rod 17 is located inside the clamping block 15.

[0042] The two sets of protective covers 18 are provided with guide rods 19 on the upper and lower sides of the electric push rod 17 on the sidewalls facing the clamping block 15. They are slidably disposed inside the clamping block 15 and are used to determine the moving direction of the protective cover 18.

[0043] Among them, an electric push rod 17 is provided inside the side wall of the two sets of clamping blocks 15. The electric push rod 17 is a Huiling Z-mod-ep-35rs-50. The working end of the electric push rod 17 extends to drive the protective cover 18 to extend. The guide rod 19 provided on the side wall of the protective cover 18 is slidably set inside the clamping block 15, so that the guide rod 19 determines the direction of the extension of the protective cover 18, ensuring the stability of the protective cover 18 when it extends. At the same time, the guide rod 19 supports the protective cover 18 when it extends, ensuring the stability of the protective cover 18 when it protects the nozzle at the end of the welding gun 6.

[0044] Adjustment mechanism 5 includes:

[0045] The lower support plate 12 is symmetrically arranged below the rotating mechanism 4.

[0050] The guide column 11 is symmetrically arranged on the top surface of the rotating frame 10, and the bottom surface of the lifting frame 8 is provided with a rotating groove, the inner wall of which is slidably connected to the end of the guide column 11.

[0051] The lifting mechanism 3 includes:

[0052] Hydraulic rod 23, which is located at the top of the movable frame 2, is used to drive the lifting frame 8 inside the movable frame 2 to move up and down;

[0053] Side protrusions 20 are located inside the first sliding grooves 22 opened on both sides of the inner wall of the lifting frame 8, and are used to guide the direction of the lifting frame 8 when it is raised or lowered.

[0054] Furthermore, by setting the rotating frame 10 to rotate under the drive of the rotating motor 9 and being positioned below the lifting frame 8, and by sliding the guide column 11 on the top surface of the rotating frame 10 onto the rotating groove on the bottom surface of the lifting frame 8 corresponding to the end of the guide column 11, the direction of rotation of the guide column 11 is restricted by the rotating groove, thereby increasing the stability of the rotating frame 10 when it is driven to rotate.

[0055] Furthermore, a hydraulic rod 23 is provided at the top of the movable frame 2, and the working end of the hydraulic rod 23 passes through the top surface of the movable frame 2 and is connected to the internal lifting frame 8, thereby realizing the adjustment of the height of the welding gun 6 held and fixed by the lower clamping block 15 by the lifting frame 8. The side protrusions 20 on both sides of the lifting frame 8 are slidably disposed inside the first sliding groove 22 opened in the inner wall of the movable frame 2, and the stability of the lifting frame 8 during lifting is limited by the first sliding groove 22.

[0056] The surface of the workbench 1 is located below the movable frame 2 and has a second slide groove 25. Inside the workbench 1, a lower connecting frame 21 is provided below the workbench 1. The movable frame 2 is located above the lower connecting frame 21. A second electric telescopic rod 24 is provided below the workbench 1 to drive the lower connecting frame 21 to move the upper movable frame 2.

[0057] The surface of the workbench 1 is symmetrically provided with guide grooves 26 on both sides of the second slide groove 25.

[0058] Finally, a lower connecting frame 21 is slidably installed below the workbench 1 via a second electric telescopic rod 24, and a movable frame 2 is installed above the lower connecting frame 21. The side wall of the lower connecting frame 21 is slidably installed inside the second sliding groove 25 opened on the surface of the workbench 1, and the ball bearings rotatably installed on the bottom surface of the guide block 27 are rotatably installed inside the guide groove 26, thereby reducing the friction between the guide block 27 and the guide groove 26 through the ball bearings.

[0059] Working principle: The worker places the welding torch 6 between two sets of clamping blocks 15. The controller controls the working end of the first electric telescopic rod 14 to extend, so that the two sets of clamping blocks 15 clamp the welding torch 6. When the welding torch 6 is in use, the protective cover 18 is close to the side wall of the clamping blocks 15. When the posture angle of the welding torch 6 needs to be adjusted, the controller controls the working end of the electric push rod 17 to extend, so that the protective cover 18 is pushed forward to the position of the nozzle at the end of the welding torch 6. At this time, the protective cover 18 protects the nozzle at the end of the welding torch 6. When the posture of the welding torch 6 is adjusted, the nozzle at the end of the welding torch 6 will not collide with external equipment or the workpiece below under the protection of the protective cover 18. In this way, the protective cover 18 protects the welding torch 6 and ensures the service life of the welding torch 6.

[0060] The controller, welding torch 6, rotary motor 9, first electric telescopic rod 14, electric push rod 17, hydraulic rod 23, and second electric telescopic rod 24 mentioned in this application are common knowledge and can be purchased and used according to actual needs, and are not within the scope of protection of this application.
