Description

Technical Field

[0001] The present invention belongs to the technical field related to orbital welding, and more specifically, particularly relates to an orbital welding robot for optimizing welding paths. Background Art

[0002] Welding robots are industrial robots used for automatic welding. Welding robots are widely used in welding operations that are repetitive, monotonous, and require long hours of work, or welding operations in high-risk and harsh environments. They can improve the labor intensity of workers, reduce the requirements for workers' operating skills, and significantly improve labor productivity, stabilize and improve the quality of welding. However, the orbital welding robots in the prior art have the following defects:

[0003] 1. In the prior art, when the welding robot body in the orbital welding robot performs linear motion on the guide rail, the welding robot body and the guide rail are usually in contact through moving wheels, so that the welding robot body performs linear motion on the guide rail. However, the limiting and fixing function in the orbital welding robot does not have a limiting and guiding function for the guide rail, so that the welding robot body shakes during the movement, which can easily cause the welding robot body to detach from the guide rail, posing certain safety hazards.

[0004] 2. In the prior art, the stability of the orbital welding robot is poor. Since there is no limiting and fixing function between the guide rail and the welding robot body, the welding robot body moves on the guide rail, making it difficult to quickly position the welding robot body, thereby affecting the precise positioning of the welding robot body when it moves to the welding position, thereby affecting the welding effect of the welding robot body.

[0005] 3. In the prior art, the limiting and fixing components in the orbital welding robot have poor limiting and fixing effects between the welding robot body and the guide rail. The clamping and fixing direction between the limiting and fixing components and the guide rail is single, and it is difficult to clamp and fix the guide rail in multiple directions. As a result, the welding robot body is prone to shaking during the welding process, thereby affecting the welding effect of the welding robot body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The track welding robot of the present invention optimizes the welding path. Through the arrangement of two fixed frames, a rotating shaft, a first roller and two slide grooves, the movement of the shell drives the movement of the two fixed frames, and the two fixed frames drive the movement of the two rotating shafts and the first rollers; the outer sides of the two first rollers are respectively in frictional contact with the inner sides of the two slide grooves to cooperate with the movement of the two first rollers, so that the two first rollers rotate and the two first rollers are respectively located in the two slide grooves, so that the shell moves smoothly and linearly on the guide rail, and the shell is prevented from being separated from the guide rail. Then, through the arrangement of four first elastic members, a second push rod, a pressure plate and a rubber plate, the elastic forces of the four first elastic members act on the four second push rods respectively, so that the two pairs of second push rods are close to each other, and the two pairs of second push rods are close to each other, driving the two pairs of pressure plates and rubber plates close to each other, so that the two pairs of rubber plates are respectively in sliding contact with the two sides of the guide rail, optimizing the welding path, and avoiding the shaking of the shell during the movement of the guide rail.

[0021] The invention provides a track welding robot for optimizing welding paths with a limited position fixing component. Through the arrangement of the movable plate, the first wear-resistant plate, the hollow elastic member, the first push rod and the second wear-resistant plate in the limited position fixing component, the movable plate continues to move downward to cooperate with the first wear-resistant plate to be held stationary by the guide rail, thereby squeezing and deforming the plurality of hollow elastic members, so that the solutions in the plurality of hollow elastic members enter the interior of the movable plate through the plurality of connecting ports. The solution inside the movable plate pushes the two first push rods away from each other, and the two first push rods move away from each other, driving the two second wear-resistant plates away from each other, so that the two second wear-resistant plates are respectively in contact with the inner side walls of the shell, so that the two second wear-resistant plates are respectively in sliding contact with the inner side walls of the shell, thereby enabling the movable plate to be limited and fixed, and the lower side of the first wear-resistant plate is in frictional contact with the upper side of the guide rail, which is beneficial to preventing the shell from being displaced on the guide rail.

Through the arrangement of the second guide block, the third push rod, the moving frame, the third wear-resistant plate, the push plate and the second elastic member, the two second sliding rods approach each other and drive the two pairs of second guide blocks approach each other. The contact surface between one end of the third push rod and the second guide block is an inclined surface. Each pair of second guide blocks moves and guides to push the two third push rods away from each other. Every two third push rods move away from each other and drive the two push plates move away from each other. Every two push plates move away from each other and push the two second elastic members and the moving frame away from each other. Every two moving frames move away from each other and drive the two third wear-resistant plates move away from each other. Every two third wear-resistant plates move away from each other and respectively make frictional contact with the upper and lower sides of the slide groove, which is beneficial to increase the friction between the shell and the guide rail. Through the arrangement of the second T-shaped push rod and the fourth wear-resistant plate, the contact surface between one end of the second T-shaped push rod and one end of the push plate is an inclined surface, and every two push plates are far away from each other, so that the two pairs of second T-shaped push rods are close to each other, and the two pairs of second T-shaped push rods approach each other, driving the two fourth wear-resistant plates to approach each other, so that the two pairs of fourth wear-resistant plates are in friction contact with the inner sides of the two slide grooves respectively, which is beneficial to further increase the friction between the shell and the guide rail, and can clamp and limit the guide rail in multiple directions through the limit fixing component, so as to avoid shaking of the welding robot body during welding.

[0047] Preferably, see Attachment Figure 3 The driving assembly includes a fixed plate 15, which is fixed in the middle of the housing 10. A rotating shaft 16 is rotatably provided at one end of the fixed plate 15. A second roller 17 is fixedly provided on the outer side of the lower end of the rotating shaft 16. The outer side of the second roller 17 is in friction contact with the inner side of the slide groove 53.

[0048] Preferably, see Attachment Figure 3 A stepper motor 19 is fixed on the upper inner side of the housing 10, a first gear 18 is fixed on the outer upper end of the rotating shaft 16, a second gear 20 is fixed on the outer output end of the stepper motor 19, the outer side of the first gear 18 is meshed with the outer side of the second gear 20, and a ring member 21 is fixed on the outer upper part of the rotating shaft 16, and the ring member 21 slides in a ring shape at one end of the inner part of the fixed plate 15.

[0049] Specific use of the present invention:

[0050] When the welding robot body 11 moves on the guide rail 14, the staff controls the drive assembly to start through the control box 12, and the stepper motor 19 starts to drive the second gear 20 to rotate, and the outer side of the second gear 20 is meshed with the outer side of the first gear 18, so that the second gear 20 rotates and drives the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 drives the second roller 17 to rotate, and the outer side of the second roller 17 is in friction contact with the inner side of the slide groove 53, so that the second roller 17 rotates and drives the housing 10 to move linearly on the guide rail 14. Among them, the rotation of the rotating shaft 16 drives the ring member 21 to slide in a ring inside one end of the fixed plate 15. Therefore, the rotating shaft 16 is vertically limited by the ring member 21.

[0051] At the same time, when the housing 10 moves on the guide rail 14, the movement of the housing 10 drives the two fixed frames 29 to move, and the two fixed frames 29 drive the two rotating shafts 39 and the first rollers 40 to move. The outer sides of the two first rollers 40 are respectively in frictional contact with the inner sides of the two slide grooves 53 to cooperate with the movement of the two first rollers 40, so that the two first rollers 40 rotate and the two first rollers 40 are respectively located in the two slide grooves 53, so that the housing 10 can move smoothly and linearly on the guide rail 14, and prevent the housing 10 from being separated from the guide rail 14. Then, the elastic forces of the four first elastic members 37 act on the four second push rods 34 respectively, so that the two pairs of second push rods 34 approach each other, and the two pairs of second push rods 34 approach each other, driving the two pairs of pressure plates 35 and rubber plates 36 to approach each other, so that the two pairs of rubber plates 36 are respectively in sliding contact with the two sides of the guide rail 14, and the shaking of the housing 10 during the movement of the guide rail 14 is prevented.

[0052] When the welding robot body 11 is performing welding work, the staff controls the fixed limit assembly to start through the control box 12, and the electric telescopic rod 22 extends to drive the movable plate 23 to move downward. The movable plate 23 moves downward to drive several hollow elastic parts 25 and the first wear-resistant plate 24 to move downward. The first wear-resistant plate 24 moves downward and contacts the upper side of the guide rail 14. At this time, the movable plate 23 continues to move downward and cooperates with the first wear-resistant plate 24 to be held immovable by the guide rail 14, thereby squeezing and deforming the plurality of hollow elastic parts 25, so that the solution in the plurality of hollow elastic parts 25 enters the interior of the movable plate 23 through the plurality of connecting ports 28, and the solution inside the movable plate 23 pushes the two first push rods 26 away from each other, and the two first push rods 26 move away from each other, driving the two second wear-resistant plates 27 away from each other, so that the two second wear-resistant plates 27 are respectively in contact with the inner side walls of the shell 10, so that the two second wear-resistant plates 27 are respectively in sliding contact with the inner side walls of the shell 10, so as to limit and fix the movable plate 23, and make the lower side of the first wear-resistant plate 24 frictionally contact with the upper side of the guide rail 14, which is beneficial to prevent the shell 10 from being displaced on the guide rail 14.

[0053] Next, the moving plate 23 moves downward to drive the two first slide bars 32 and the two first piston plates 31 to move downward. The two first piston plates 31 move downward to squeeze the solutions in the two cylinders 30 into the two fixed frames 29 respectively. The solutions in the two fixed frames 29 push the two second piston plates 41 to approach each other. The two second piston plates 41 approach each other to drive the two second slide bars 42 to approach each other. The two second slide bars 42 approach each other to drive the two pairs of first guide blocks 43 to approach each other. The contact surface between one end of the first T-shaped push rod 38 and the first guide block 43 is an inclined surface, so that each pair of first guide blocks 43 moves to push the two first T-shaped push rods 38 away from each other, and each two first T-shaped push rods 38 move away from each other to squeeze the two first elastic members 37 to generate elastic force. At this time, the elastic forces further generated by the four first elastic members 37 act on the four second push rods 34 respectively, so that the two pairs of second push rods 34 move closer to each other, so as to increase the friction between the two pairs of rubber plates 36 and the two side walls of the guide rail 14, which is beneficial to the limiting and fixing effect between the housing 10 and the guide rail 14. Among them, the two second slide bars 42 move closer to each other to drive the two arc-shaped wear-resistant plates 45 to move closer to each other, so that the inner sides of the two arc-shaped wear-resistant plates 45 are respectively in friction contact with the outer sides of the two first rollers 40, which is beneficial to the limiting and fixing effect of the two first rollers 40.

[0054] Then, the two second sliding rods 42 approach each other, driving the two pairs of second guide blocks 44 to approach each other. Through the inclined contact surface between one end of the third push rod 46 and the second guide block 44, each pair of second guide blocks 44 moves and guides the two third push rods 46 away from each other. Every two third push rods 46 move away from each other, driving the two push plates 51 away from each other. Every two push plates 51 move away from each other and push the two second elastic members 52 and the moving frame 47 away from each other. Every two moving frames 47 move away from each other and drive the two third wear-resistant plates 48 away from each other. Every two third wear-resistant plates 48 move away from each other and make frictional contact with the upper and lower sides of the slide groove 53 respectively, which is beneficial to increase the friction between the shell 10 and the guide rail 14.
