[0018] like Figure 1-Figure 8 A multi-axis robotic arm welding robot is shown, comprising a base 1 and a welding robot 2 installed at the upper rear edge of the base 1. Since welding by the welding robot 2 is a prior art and has been widely used, it is not described in detail here. Two outer positioning arc plates 7 are respectively arranged near the middle of the upper end of the base 1. Two positioning ears 16 extend from the front ends of the two outer positioning arc plates 7. The positioning ears 16 play a role in positioning the front and rear positions of the bracket seat 39. A support column is installed at the front end of the upper end of the base 1. 19, two inner positioning arc plates 24 are slidably installed at the rear end of the carrier column 19, and the outer positioning arc plate 7 and the inner positioning arc plate 24 are designed according to the surface curvature of the bracket seat 39, so that when the subsequent outer positioning arc plate 7 and the inner positioning arc plate 24 are attached to the bracket seat 39, they can fully contact with it to accurately position and fix it. The two inner positioning arc plates 24 are located between the two outer positioning arc plates 7, and a pushing member is provided at the front edge of the upper end of the base 1. Three arc seats 13 are provided in a circular array above the two outer positioning arc plates 7, and the pushing member is provided at the upper front edge of the base 1. The arc seat 13 is connected to the arc seat 13, and the arc seat 13 is designed according to the curvature of the inner surface of the bracket ring 40, so that when the top is supported later, the arc seat 13 can fully contact the bracket ring 40. A hole-fixing column 14 extends from the middle of one of the arc seats 13. The hole-fixing column 14 is designed according to the size of the mounting hole on the bracket ring 40, so that when the hole-fixing column 14 is inserted into the mounting hole on the bracket ring 40, the two can fit tightly, thereby accurately positioning the bracket ring 40. The outer surface of the carrier column 19 is elastically installed with a pull sleeve 23, and the two sides of the pull sleeve 23 are connected to the two inner fixing blocks. An H-shaped frame 17 is connected between the positioning arc plates 24. The shifting sleeve 23 can drive the H-shaped frame 17 to move to push the inner positioning arc plates 24, so that the two inner positioning arc plates 24 can be synchronously extended to both sides to be fixed on the inner sides of the bracket seat 39. A bridge frame 22 extends from the upper end of the shifting sleeve 23, and the bridge frame 22 plays a connecting role. A shifting rod 5 is fixedly installed in the middle of the side of the bridge frame 22, and the pushing member is attached to the end of the shifting rod 5. The shifting rod 5 can be driven by the pushing sleeve 35 to drive the shifting sleeve 23 to slide on the carrier column 19.

[0019] A No. 1 frame ear 18 is extended from both sides of the pull sleeve 23, and one end of the H-shaped frame 17 is rotatably connected to the No. 1 frame ear 18. A No. 2 frame ear 27 is extended from the middle of the opposite surfaces of the two inner positioning arc plates 24. The No. 1 frame ear 18 and the No. 2 frame ear 27 both serve to facilitate the connection of the H-shaped frame 17, and the other end of the H-shaped frame 17 is rotatably connected to the No. 2 frame ear 27.

[0020] A fixing plate 6 is fixedly installed at the front edge of the lower end of the supporting column 19, and the end of the fixing plate 6 is fixed to the base 1. The fixing plate 6 supports and fixes the supporting column 19. A spring body 20 is embedded inside the front end of the supporting column 19, and a spring cap 21 is embedded at the end of the spring body 20. The spring body 20 can push the spring cap 21 to reset the moved sleeve 23, and the end of the bridge 22 is fixed to the spring cap 21.

[0021] Two guide shells 25 are symmetrically embedded in the rear end of the support column 19, and two guide frames 26 are slidably installed inside the guide shells 25. The cooperation between the guide shells 25 and the guide frames 26 serves to guide the inner positioning arc plate 24. The two guide frames 26 extend from both ends of the guide shells 25 respectively, and the ends of the guide frames 26 are fixed to the inner positioning arc plate 24.

[0022] The pushing member includes a stand 3 fixedly mounted at the front edge of the upper end of the base 1, a threaded column 10 is rotatably mounted on the end of the stand 3, and the stand 3 plays a role in carrying the threaded column 10, a threaded sleeve 36 is screwed on the outer surface of the threaded sleeve 10, and an inclined frame 37 is rotatably mounted on the rear end of the threaded sleeve 36, and the threaded column 10 can drive the threaded sleeve 36 to move, thereby driving the inclined frame 37 to move, and a push sleeve 35 is connected to the end of the inclined frame 37, and a ring body 11 is slidably connected to the rear of the push sleeve 35, and the inclined frame 37 plays a role in pushing the push sleeve 35, and a synchronous frame 4 is connected to the push sleeve 35, and a dial ring 8 is inlaid at one end of the synchronous frame 4, and the synchronous frame 4 can push the lever 5 under the drive of the push sleeve 35, and the dial ring 8 fits with the end of the lever 5, and the dial ring 8 can increase the contact surface with the lever 5, so as to facilitate pushing the lever 5, and three positioning columns 12 are arranged in an annular array at the rear end of the ring body 11, and the positioning columns 12 play a role in positioning the front and rear positions of the bracket ring 40.

[0023] A three-sided frame 28 is embedded in the interior of the ring body 11, and the opposite surfaces of the three arc seats 13 are fixedly installed with a seat frame 15. The three-sided frame 28 serves to guide the seat frame 15, and the seat frame 15 slides through the interior of the three-sided frame 28. The end of the seat frame 15 is rotatably installed with an expansion frame 30, and the seat frame 15 serves to carry the arc seat 13. The end of the expansion frame 30 is rotatably installed with a groove seat 31, and the groove seat 31 serves to facilitate the connection of the expansion frame 30. The end of the groove seat 31 is fixed to the rear part of the outer surface of the push sleeve 35. The push sleeve 35 can drive the expansion frame 30 to move, so as to push the three seat frames 15 at the same time, so that the three arc seats 13 can move outward synchronously to support and fix the inner wall of the bracket ring 40, so that the bracket ring 40 can be close to the upper end of the bracket seat 39.

[0024] The front end of the push sleeve 35 is inlaid with a socket 34, and the end of the inclined frame 37 is rotatably installed inside the socket 34. The socket 34 serves to facilitate the connection of the inclined frame 37. The interior of the three-side frame 28 is inlaid with a limiting column 29, and the seat frame 15 is slidably installed on the outer surface of the limiting column 29. The limiting column 29 serves to prevent the seat frame 15 and the three-side frame 28 from separating. The other end of the synchronous frame 4 is inlaid with a connecting ring 33, and the connecting ring 33 is inlaid on the front surface of the outer surface of the push sleeve 35. The connecting ring 33 serves to fix the synchronous frame 4 and the push sleeve 35 together.

[0025] A boss 32 extends from the middle of the front end of the three-sided frame 28, and a push sleeve 35 is slidably mounted on the outer surface of the boss 32. The boss 32 guides the push sleeve 35. A fixing rod 9 extends from the lower front end of the ring body 11. The end of the fixing rod 9 is fixed to the stand 3, and the fixing rod 9 fixes the ring body 11. The synchronous frame 4 is slidably mounted on the outer surface of the fixing rod 9. A guide ridge 38 is embedded through the upper end of the stand 3. The front end of the threaded sleeve 36 is slidably mounted on the outer surface of the guide ridge 38. The guide ridge 38 can ensure that the threaded sleeve 36 will not rotate synchronously when the threaded column 10 rotates.

[0026] During welding, the bracket seat 39 is pushed horizontally between the two outer positioning arc plates 7 on the ground seat 1. At this time, the two outer positioning arc plates 7 are attached to the two sides of the bracket seat 39, and the positioning ears 16 are attached to the front end of the bracket seat 39 to position the bracket seat 39. Then, the bracket ring 40 is sleeved on the outer side of the three arc seats 13. At this time, the positioning column 12 is pressed against the front end of the bracket ring 40. At the same time, the mounting hole on the bracket ring 40 corresponds to the hole fixing column 14. Then, the threaded column 10 is rotated, and the inclined frame 37 is driven to move through the threaded sleeve 36 to push the push sleeve 35, so that the expansion frame 30 on the push sleeve 35 can move, so as to push the three seat frames 15 at the same time, so that the three arc seats 13 can be moved outward synchronously to support and fix the inner wall of the bracket ring 40, so that the bracket ring 40 can be tightly attached to the upper end of the bracket seat 39. At this time, the hole fixing column 14 is inserted into the mounting hole on the bracket ring 40 to accurately position the bracket ring 40 on the bracket seat 39, so that when the subsequent welding robot 2 welds the two into an integral bracket, the mounting hole on the bracket is in the correct position to meet the subsequent installation requirements. At the same time, the above-mentioned push sleeve 35 will also push the lever 5 through the synchronous frame 4 during the movement, so that the push sleeve 23 can slide on the carrier column 19, thereby driving the H-shaped frame 17 to move, so as to push the inner positioning arc plate 24, so that the two inner positioning arc plates 24 can be synchronously extended to both sides to be fixed on the inner sides of the bracket seat 39, thereby fixing the bracket seat 39 and the bracket ring 40 at the same time, and then the welding robot 2 can be used to weld the connection between the bracket seat 39 and the bracket ring 40 to make a complete bracket.
