[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1~Figure 5 As shown, this embodiment proposes a track welding robot, including

[0029] A welding robot body 1, wherein a chassis 2 is disposed at the lower end of the welding robot body 1;

[0030] A driving assembly 3, wherein the driving assembly 3 is arranged at the bottom of the chassis 2;

[0031] A limit assembly 4, the limit assembly 4 is connected to the lower end of the chassis 2;

[0032] The driving assembly 3 includes a limiting track 3-1, which is mounted on the outside of the chassis 2. An inner cavity groove 3-2 is arranged in the limiting track 3-1. A sliding plate is connected to the lower end of the chassis 2. The sliding plate is embedded in the inner cavity groove 3-2. A sliding groove is opened on the sliding plate. A wheel axle 3-3 is arranged in the sliding groove. A limiting sliding wheel 3-4 is mounted on the wheel axle 3-3. The limiting sliding wheel 3-4 and the wheel axle 3-3 are movably mounted through a bearing. A connecting frame 3-5 is arranged at the bottom of the sliding plate. A driving shaft 3-6 is inserted and connected to the connecting frame 3-5. Moving wheels 3-7 are arranged at opposite ends of the driving shaft 3-6.

[0033] In this embodiment, the limiting sliding wheel 3-4 and the moving wheel 3-7 in the driving component 3 move in the limiting track 3-1, and the moving wheel 3-7 moves on the bottom surface of the inner cavity groove 3-2. The driving shaft 3-6 movably inserts the moving wheel 3-7, so that the moving wheel 3-7 is driven by the driving shaft 3-6 to rotate, thereby realizing the movement of the welding robot body 1 in the limiting track 3-1.

[0034] Specifically, the side wall of the connecting frame 3-5 is provided with an output motor 3-8, and the output end of the output motor 3-8 is connected to the moving wheel 3-7.

[0035] In this embodiment, the output motor 3-8 drives the drive shaft 3-6 to rotate, and the drive shaft 3-6 drives the moving wheel 3-7 to rotate, thereby realizing the power for the sliding plate to move in the limiting track 3-1.

[0036] Furthermore, the limit assembly 4 includes an anti-collision plate 4-1, which is arranged on the opposite side walls of the inner cavity groove 3-2, an indicator light 4-2 is arranged on the anti-collision plate 4-1, a push switch 4-3 is arranged on the side wall of the anti-collision plate 4-1, a buffer spring 4-4 ​​is arranged on the side wall of the anti-collision plate 4-1, a contact plate 4-5 is arranged at the end of the buffer spring 4-4, and a contact protrusion 4-6 is arranged on the back of the contact plate 4-5, and the contact protrusion 4-6 corresponds to the position between the push switch 4-3.

[0037] In this embodiment, the buffer spring 4-4 ​​on the anti-collision plate 4-1 is used for buffering during collision. When the sliding disk moves onto the contact plate 4-5, it presses on the push switch 4-3 through the contact protrusion 4-6. At this time, the push switch 4-3 is closed and the indicator light 4-2 lights up. The welding robot body 1 will only press on the contact plate 4-5 when the travel distance exceeds the range of movement. This structure is to prevent errors when the output motor 3-8 drives the welding robot body to move.

[0038] Furthermore, connecting plates 5 are provided on opposite side walls of the limiting track 3 - 1 , and bolt holes 6 are formed on the connecting plates 5 .

[0041] In this embodiment, the limiting strip 7 is used to limit the sliding plate so that the sliding plate cannot be bumped, and the limiting sliding wheels 3 - 4 are pressed against the inner top of the limiting strip 7 .

[0042] Furthermore, the indicator light 4-2 is powered by a lithium battery, the contact protrusion 4-6 presses the push switch 4-3, there are multiple connecting plates 5, and several connecting plates 5 are evenly distributed on the opposite side walls of the limiting track 3-1, and the connecting frame 3-5 and the driving shaft 3-6 are connected through a bearing.

[0043] When the welding robot body 1 needs to move, the output motor 3-8 drives the drive shaft 3-6 to rotate, and the drive shaft 3-6 drives the moving wheel 3-7 to move in the limit track 3-1, and the limit sliding wheel 3-4 contacts the limit bar 7 for limiting. When the output motor 3-8 drives the welding robot body to move and an error occurs that exceeds the range of movement, the sliding disk moves to the contact plate 4-5 and presses on the push switch 4-3 through the contact protrusion 4-6. At this time, the push switch 4-3 is closed and the indicator light 4-2 lights up.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
