[0002] Welding robots are mechanical devices that use robotic arms to perform welding work instead of manual labor. They are characterized by high work efficiency and can also avoid the chance of accidents that may occur during manual welding. Before using a welding robot, it needs to be transported to the predetermined position on the processing line.

[0004] This device, equipped with a rotating air intake hood and an extraction mechanism, extracts fumes and sparks, reducing spark splashing and fume dispersion, thus increasing the convenience of subsequent processing. However, this device cannot transport the welding robot, which prevents the welding robot from welding workpieces at a distance. Utility Model Content

A lead screw is rotatably connected to the right side of the first fixed plate, and a first limiting rod is symmetrically fixedly connected to the right side of the first fixed plate. A movable seat is threaded onto the surface of the lead screw, and support rollers are fixedly connected at equal intervals to the bottom of the movable seat.

[0008] Preferably, the movable seat has a hole on its left side that matches the first limiting rod, and the movable seat is slidably connected to the surface of the first limiting rod through the hole. The first limiting rod limits the movable seat, so that the movable seat moves left and right as the lead screw rotates.

The tops of the four fixing rods are fixedly connected to a fixed seat. A rectangular limiting ring is fixedly connected to the top of the fixed seat.

[0012] Preferably, the bottom of the fixed frame is fixedly connected to the top of the movable seat.

[0013] Compared with the prior art, this utility model provides a conveying auxiliary device for a welding robot, which has the following beneficial effects: The conveying auxiliary device of this welding robot has a conveying mechanism in which a first servo motor drives a lead screw to rotate, which, together with a first limit rod, limits the movement of the moving seat, enabling the moving seat to move smoothly and accurately from side to side. At the same time, the support rollers at the bottom of the moving seat contact the top of the base, further enhancing the stability of the moving seat during movement, ensuring a smooth and reliable conveying process, and reducing the impact of shaking or deviation on the welding work.

[0014] The conveying auxiliary device of this welding robot employs a bidirectional lead screw drive design for its fixing mechanism. A second servo motor drives the bidirectional lead screw to rotate, and under the limitation of a second limit rod, the two moving blocks can move towards each other. The moving blocks drive the L-block and the limit frame to move via a sliding column, thereby achieving rapid and stable clamping of the welding robot. The rubber pads on the inner wall of the limit frame not only increase the friction with the welding robot and prevent it from slipping, but also provide cushioning and protection, avoiding damage to the surface of the welding robot during clamping.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides the following technical solution: Example

[0020] Please see Figure 1-4 This utility model provides a technical solution: a conveying auxiliary device for a welding robot, including a base 1, fixing pins 2 are equidistantly arranged on the left and right sides of the top of the base 1, a conveying mechanism 3 is arranged on the top of the base 1, and a fixing mechanism 4 is arranged on the top of the conveying mechanism 3. The conveying mechanism 3 includes a first fixed plate 31 and a second fixed plate 32. The first fixed plate 31 and the second fixed plate 32 are symmetrically fixed to the top of the base 1. A lead screw 33 is rotatably connected to the right side of the first fixed plate 31. A first limiting rod 34 is symmetrically fixed to the front and back of the right side of the first fixed plate 31. A movable seat 35 is threaded to the surface of the lead screw 33. Support rollers 36 are fixedly connected at equal intervals to the bottom of the movable seat 35. A first servo motor 37 is fixedly connected to the right side of the second fixed plate 32.

[0021] The right end of the lead screw 33 is rotatably connected to the output end of the first servo motor 37, the right end of the first limit rod 34 is fixedly connected to the left side of the second fixed plate 32, and the surface of the support roller 36 is in contact with the top of the base 1 to support the moving seat 35.

[0022] The movable seat 35 has a hole on its left side that matches the first limiting rod 34. The movable seat 35 is slidably connected to the surface of the first limiting rod 34 through the hole. The first limiting rod 34 limits the movable seat 35, so that the movable seat 35 moves left and right as the lead screw 33 rotates. Example

[0023] Please see Figure 5-6 Furthermore, based on Embodiment 1, a fixing mechanism 4 is obtained.

[0024] The fixing mechanism 4 includes fixing rods 41, which are symmetrically fixed to the top of the movable seat 35. The top of the four fixing rods 41 is fixedly connected to a fixed seat 42. A rectangular limiting ring 43 is fixedly connected to the top of the fixed seat 42. A fixing frame 44 is fixedly connected to the bottom of the fixed seat 42. A two-way screw rod 45 is rotatably connected to the front and rear sides of the inner wall of the fixed frame 44. A second limiting rod 49 is symmetrically fixed to the front and rear sides of the inner wall of the fixed frame 44. A movable block 46 is symmetrically threaded to the front and rear of the two-way screw rod 45. A second servo motor 48 is fixedly connected to the front of the fixed frame 44. A sliding column 47 is symmetrically fixed to one side of the two movable blocks 46. An L-block 411 is fixedly connected to the other end of the sliding column 47. A limiting frame 412 is fixedly connected to the other end of the L-block 411. A rubber pad 413 is fixedly connected to the inner wall of the limiting frame 412.

[0025] The output end of the second servo motor 48 is fixedly connected to the front end of the bidirectional lead screw 45. The two moving blocks 46 have holes on one side that match the second limiting rod 49. The two moving blocks 46 are slidably connected to the surface of the second limiting rod 49 through the holes. The second limiting rod 49 limits the two moving blocks 46, so that the two moving blocks 46 move towards each other as the bidirectional lead screw 45 rotates.

[0026] The fixed frame 44 has grooves on the front and rear sides that match the sliding column 47, and the surface of the sliding column 47 is slidably connected to the groove.

[0027] The bottom of the fixed frame 44 is fixedly connected to the top of the movable base 35.

[0028] In actual operation, when this device is used, during the transmission process, after the first servo motor 37 is started, its output end drives the lead screw 33 to rotate. Since the moving seat 35 is threadedly connected to the lead screw 33, and under the limiting action of the first limiting rod 34, the moving seat 35 cannot rotate synchronously with the lead screw 33. It can only move smoothly in the left and right directions along the lead screw 33 and the first limiting rod 34. At the same time, the support roller 36 at the bottom of the moving seat 35 contacts the top of the base 1, providing effective support for the moving seat 35, reducing frictional resistance during the movement, and ensuring that the moving seat 35 can stably and smoothly drive the top fixing mechanism 4 and the welding robot to the designated welding position. During the fixing process, the robot to be welded is placed inside the rectangular limiting ring 43 on the top of the fixing base 42. The rectangular limiting ring 43 first plays a preliminary limiting role for the welding robot to prevent large displacement of the welding robot. Subsequently, the second servo motor 48 is started, and its output end drives the bidirectional lead screw 45 to rotate. Under the limitation of the second limiting rod 49, the two moving blocks 46 threadedly connected to the bidirectional lead screw 45 can only move in opposite directions along the second limiting rod 49. When the moving blocks 46 move, the sliding column 47 on one side drives the L block 411 and the limiting frame 412 to move synchronously, so that the two limiting frames 412 gradually approach and clamp the welding robot. The rubber pad 413 on the inner wall of the limiting frame 412 can not only increase the friction between the welding robot and improve the fixing firmness, but also avoid damage to the surface of the welding robot during the clamping process, thereby achieving reliable fixing of the welding robot.
