[0006] Furthermore, the movable support assembly includes a support shell, a guide rod is fixedly installed on the outer side of the support shell in the vertical direction, a sliding sleeve is slidably connected to the guide rod in the axial direction, a movable wheel is provided inside the support shell, the movable wheel and the sliding sleeve are welded together by a connecting rod, and a through groove adapted to the connecting rod is also provided on the outer side of the support shell.

[0007] Furthermore, the drive locking assembly includes a rectangular seat, which is fixedly connected to the center position of the bottom of the support base. A storage cavity is provided in the rectangular seat corresponding to the position of the support shell. A transverse block is slidably connected in the storage cavity. A locking plug for fixed connection of the sliding sleeve is fixedly connected to the side of the transverse block near the support shell.

[0008] Furthermore, a transmission cavity is provided at the center of the rectangular base, and a screw is rotatably connected inside the storage cavity. One end of the screw passes through the transmission cavity and is fixedly connected to a driven bevel gear that cooperates with the driving bevel gear. A guide slider is fixedly connected to the outside of the transverse block, and the guide slider is slidably connected to a groove on the inner wall of the storage cavity.

[0010] Furthermore, a lifting cylinder is installed in the groove at the bottom of the rectangular base, and a lifting plate is fixedly installed on the drive end of the lifting cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the welding robot body needs to be moved, this invention controls the lifting cylinder to move the lifting plate, lifting the support and the welding robot body on it. At this time, under the action of gravity, the moving wheel drives the sliding sleeve to move vertically downward and extend to the outside of the support shell. The guide rod is used for limiting, and then the stepper motor is controlled to start, so that its output shaft drives the active bevel gear to rotate. The driven bevel gear meshing with it can drive the screw to rotate under the connection of the limiting rotating ring. The transverse block threaded to it can drive the locking block to move to one side of the support shell and insert it into the sliding sleeve through the limiting of the guide slider, forming With the moving wheels fixed, after the lifting cylinder drives the lifting plate back to its original position, the four moving wheels provide rolling support. Similarly, in the working state of the welding robot, the locking block disengages from the sliding sleeve, and the four support shells provide stable support for the support base. This mobile welding robot has a reasonable structural design and is easy to use. It adopts a retractable roller design, which can be released when it needs to be moved for easy pushing and transfer. In the working state, the rollers can be retracted to form a stable support, thereby ensuring the stability during welding and improving the welding quality of the product.

[0022] A transmission cavity 45 is provided at the center of the rectangular base 41. A screw 46 is rotatably connected in the receiving cavity 42. One end of the screw 46 passes through the transmission cavity 45 and is fixedly connected to a driven bevel gear 47 that works with the driving bevel gear 6. A guide slider 48 is fixedly connected to the outside of the transverse block 43. The guide slider 48 is slidably connected in a groove on the inner wall of the receiving cavity 42. A limiting ring 49 is fixedly connected to the surface of the screw 46 at the position between the receiving cavity 42 and the transmission cavity 45. The limiting ring 49 is movably connected to the rectangular base 41. The limiting ring 49 can prevent the screw 46 from moving axially and ensure its stability during rotation.

[0023] A lifting cylinder 410 is installed in a groove at the bottom of the rectangular base 41, and a lifting plate 411 is fixedly installed on the drive end of the lifting cylinder 410.

[0024] This mobile welding robot features a reasonable structural design and is easy to use.

In the working state, the rollers can be retracted to form a stable support, thereby ensuring the stability of welding and improving the welding quality of the product.

[0025] Working principle: When the welding robot body 2 needs to be moved, the lifting cylinder 410 is controlled to drive the lifting plate 411 to move, lifting the support 1 and the welding robot body 2 on it. At this time, under the action of gravity, the moving wheel 34 drives the sliding sleeve 33 to move vertically downward and extend to the outside of the support shell 31. The guide rod 32 is used for limiting. Then, the stepper motor 5 is controlled to start, so that its output shaft drives the active bevel gear 6 to rotate. The driven bevel gear 47 meshing with it can drive the screw 46 to connect with the limiting rotating ring 49. When the robot rotates downwards, the transverse block 43, which is threaded onto it, is limited by the guide slider 48, which can drive the locking block 44 to move towards the support sleeve 31 and insert it into the sliding sleeve 33 to fix the moving wheel 34. After the lifting cylinder 410 drives the lifting plate 411 back to its original position, the four moving wheels 34 can be used for rolling support. Similarly, when the welding robot is working, the locking block 44 is disengaged from the sliding sleeve 33, and the four support sleeves 41 can be used to achieve stable support for the support base 1.
