Specific implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1-5 , an embodiment provided by the present utility model: It includes a correction box 1. A placing groove 2 is opened inside the correction box 1. A circular groove 3 is opened at the bottom of the inner wall of the placing groove 2. Two groups of clamping plates 4 are arranged inside the placing groove 2. A moving component 5 is arranged in the placing groove 2. A limit component 6 is arranged on the front side of the correction box 1;

[0032] The moving component 5 is used to drive the two sets of clamping plates 4 to move inward or outward simultaneously, so as to limit the position of the welding torch. The limiting component 6 is used to assist in correcting and limiting the welding torch. When the robot welding torch needs to be corrected after use, the bottom of the robot welding torch can be placed inside the placing groove 2 at this time. At this time, under the action of the self-gravity of the robot welding torch, the moving component 5 will drive the clamping plate 4 to move inward, so as to correct the robot welding torch. At this time, the front side of the robot welding torch will be on the front side of the correction box 1. At this time, under the action of the limiting component 6, the robot welding torch will be limited, thereby improving the accuracy during the correction of the robot welding torch.

[0033] Referring to Figures 1-5 , the moving component 5 includes a disc 51. Both sides of the disc 51 are rotatably installed with first connecting rods 52. The front side of the first connecting rod 52 is fixedly installed with a connecting rod 53. The front end of the connecting rod 53 is fixedly installed with a second connecting rod 54. The top of the second connecting rod 54 and the bottom of the clamping plate 4 are rotatably installed. Through the mutual cooperation of the disc 51, the first connecting rod 52, the connecting rod 53 and the second connecting rod 54, when the bottom of the robot welding torch contacts the top of the disc 51, at this time, due to the self-gravity of the robot welding torch, the disc 51 will move downward. The disc 51 moving downward drives the first connecting rod 52 to gradually change from an inclined state to a vertical state. At this time, the first connecting rod 52 will drive the connecting rod 53 to rotate. The connecting rod 53 rotating drives the second connecting rod 54 to rotate. The second connecting rod 54 rotating drives the clamping plate 4 to move inward to limit and correct the robot welding torch. The back of the connecting rod 53 penetrates to the back of the first connecting rod 52. A bearing seat 55 is rotatably installed on the surface of the connecting rod 53. The outside of the bearing seat 55 and the inside of the correction box 1 are fixedly installed. Through the setting of the bearing seat 55, the connecting rod 53 can be limited, and the stability of the connecting rod 53 during rotation can also be improved. The front side and the back side of the clamping plate 4 are both fixedly installed with limiting blocks 56. Limiting grooves 57 are opened on the front side and the back side of the inner wall of the correction box 1. The limiting blocks 56 and the limiting grooves 57 are slidably installed. Through the mutual cooperation of the limiting blocks 56 and the limiting grooves 57, the clamping plate 4 can be limited to prevent the clamping plate 4 from shaking during movement, resulting in the clamping plate 4 being unable to move linearly to correct the robot welding torch. The bottom of the disc 51 is fixedly installed with a round rod 58. The bottom of the round rod 58 penetrates into the inside of the round groove 3. A spring 59 is fixedly installed at the bottom of the inner wall of the round groove 3. The top of the spring 59 and the bottom of the round rod 58 are fixedly installed. Through the mutual cooperation of the round rod 58 and the spring 59, when the robot welding torch presses down the disc 51, it will drive the round rod 58 into the round groove 3. At this time, the round rod 58 will compress the spring 59. When the robot welding torch and the disc 51 are separated, at this time, under the action of the spring 59, the disc 51, the first connecting rod 52, the second connecting rod 54 and the clamping plate 4 will be reset for the next use.

[0034] Referring to Figures 1-5, the limiting component 6 includes a limiting sleeve 61. The back surface of the limiting sleeve 61 is fixedly installed on the front side of the correction box 1. A limiting rod 62 is slidably installed inside the limiting sleeve 61. A rotating wheel 63 is rotatably installed on the inner side of the limiting rod 62. Through the mutual cooperation of the limiting sleeve 61, the limiting rod 62 and the rotating wheel 63, when the limiting rod 62 is pushed inward, the rotating wheel 63 can be driven to move inward. When the surface of the rotating wheel 63 contacts the robotic welding torch, at this time, the rotating wheel 63 can not only limit the robotic welding torch, but also correct the robotic welding torch. A tension spring 64 is arranged inside the limiting sleeve 61. Both ends of the tension spring 64 are fixedly installed on the inner side of the limiting rod 62. Through the arrangement of the tension spring 64, the limiting rod 62 can always bear the pulling force of the tension spring 64, so that the effect of correcting the robotic welding torch by the rotating wheel 63 is better.

[0035] Working principle: When the robotic welding torch needs to be corrected after use, the bottom of the robotic welding torch can be placed inside the placement groove 2 at this time. When the bottom of the robotic welding torch contacts the top of the disc 51, the disc 51 will move downward due to the gravity of the robotic welding torch itself. The downward movement of the disc 51 drives the round rod 58 to move downward. The downward movement of the round rod 58 drives the first connecting rod 52 to gradually change from an inclined state to a vertical state. At this time, the first connecting rod 52 drives the connecting rod 53 to rotate. The rotation of the connecting rod 53 drives the second connecting rod 54 to rotate. The rotation of the second connecting rod 54 drives the clamp plate 4 to move inward to correct the robotic welding torch. Then, under the action of the tension spring 64, the limiting rod 62 and the rotating wheel 63 will move inward. When the surface of the rotating wheel 63 contacts the robotic welding torch, at this time, the rotating wheel 63 can not only limit the robotic welding torch, but also assist in correcting the robotic welding torch.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
