DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in 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 in 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.

[0017] Example: Figure 1-4 As shown, the utility model provides a robot production welding device, including a base 1, two groups of symmetrically distributed support seats 11 are fixedly installed on the top of the base 1, and a first rotating shaft 12 is rotatably installed on the top of each group of support seats 11, and a conveyor belt 13 is provided on the outer movable sleeve of the first rotating shaft 12. A plurality of evenly distributed placement tables 14 are fixedly installed on the outer surface of the conveyor belt 13, and a fixing component 15 is provided on each placement table 14. A welding gun 16 is provided on the top of the conveyor belt 13, and a cooling box 17 is provided on the outside of the conveyor belt 13. The cooling box 17 is located on one side of the welding gun 16, and a gear 3 is fixedly installed on the outside of one of the first rotating shafts 12, a support frame 31 is fixedly installed at the top edge of the base 1, and a fixed seat 32 is fixedly pressed at the top edge of the support frame 31, and a second rotating shaft 33 is rotatably installed on the top of the fixed seat 32, and the second rotating shaft 33 is rotatably inserted in the corresponding support seat 11, and a half-face gear 34 used in conjunction with the gear 3 is fixedly installed on the outside of the second rotating shaft 33.

[0018] A base plate 4 is fixedly installed between the two groups of support seats 11, and a protective cover 41 is fixedly installed on the top of the base plate 4. The protective cover 41 is located outside the welding gun 16 and the conveyor belt 13, and the protective cover 41 is located in the middle position of the base plate 4. By setting the protective cover 41, sparks generated during welding of parts can be prevented from splashing onto the workers and causing injuries to the workers.

[0019] A cooling motor 5 is fixedly installed on the top of the cooling box 17, and a cooling fan 51 is fixedly installed on the driving end of the cooling motor 5. By setting the cooling motor 5, when the cooling motor 5 is started, the cooling fan 51 is driven to rotate, thereby blowing cold air to the welded parts in the cooling box 17 to cool the welded parts.

[0020] The fixing assembly 15 includes a double-headed screw 6 with opposite threads at both ends, the outer side of the double-headed screw 6 is threadedly connected with two symmetrically distributed movable plates 61, the top of the movable plate 61 is fixedly installed with a clamping plate 62, the outer rotating sleeve of the double-headed screw 6 is provided with two symmetrically distributed fixed blocks 63, and an empty groove 64 is opened in the middle of the top of the placement table 14, and the two fixed blocks 63 are fixed in the empty groove 64. By setting up the fixing assembly 15, when the double-headed screw 6 is rotated by the rotating wheel, the threaded connection between the double-headed screw 6 and the movable plate 62 drives the clamping plate 61 to move toward the middle to clamp the parts or to move to both sides to release the parts.

[0021] Two symmetrically distributed trapezoidal blocks 7 are fixedly installed at the bottom edge of each splint 62, and two symmetrically distributed trapezoidal grooves 71 are opened at the top of each placement table 14. The trapezoidal blocks 7 are slidably engaged in the corresponding trapezoidal grooves 71. By setting the trapezoidal blocks 7 and the trapezoidal grooves 71, the splint 62 is more stable when moving to the middle or to both sides. At the same time, the splint 62 is limited to prevent it from rotating with the rotation of the double-headed screw 6.

[0022] A motor 35 is fixedly mounted on the top of the support frame 31 , and a driving end of the motor 35 is fixed to the end of the second rotating shaft 33 . By setting the motor 35 , when the motor 35 is started, the second rotating shaft 33 is driven to rotate, thereby driving the half-face gear 34 to rotate.

[0023] Working principle: In actual use, the parts to be welded are placed on the placement table 14 on the right side of the protective cover 41, and then the parts to be welded are fixed by the fixing component 15, and then the motor 35 is started to drive the second rotating shaft 33 to rotate, thereby driving the half-face gear 34 to rotate, and then when the half-face gear 34 is meshed with the gear 3, the first rotating shaft 12 is driven to rotate, thereby driving the conveyor belt 13 to rotate, and the parts to be welded are transported. When the half-face gear 34 is not meshed with the gear 3, the parts to be welded are located in the protective cover 41 below the welding gun 16, and then the parts are welded by the welding gun 16, and then when the half-face gear 34 is meshed with the gear 3 again, the welded and unwelded parts are transported, and then when the half-face gear 34 is not meshed with the gear 3 again, the welded parts are transported to the cooling box 17, and the unwelded parts are transported to the protective cover 41. At the same time, the unwelded parts are placed on the placement table 14 on the right side of the protective cover 41, and then welding cooling is performed;

[0024] Then, when the cooled parts are transferred to the right side of the protective cover 41, the cooled parts are replaced with unwelded parts, and the operation is repeated.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
