[0028] Furthermore, in order to reduce the friction between the arc ring 1 404 and the arc ring 2 406 and the rectangular rod 12 and the round rod 13, the surfaces of the arc ring 1 404 and the arc ring 2 406 are set to be smooth.

[0029] Furthermore, in order to increase the stability and wear resistance of the slide post 6 in clamping the small circular ring 10 and the large circular ring 11 , a rubber sleeve is provided at a portion of each slide post 6 that contacts the small circular ring 10 and the large circular ring 11 .

[0030] The working steps of this embodiment are: The following rotations are from front to back, from top to bottom, and from right to left. When in use, first place the environmentally friendly furniture production welding device at the required position; The operator connects an external power supply to all parts that need to be powered by electricity, connects an external air pump to the vertical pipe 305, and connects an external welding robot to the lower part of the base frame 1. When welding the round table tripod, the operator places the small ring 10 on several sliding columns 6 on the left, and the small ring 10 is close to the right side of the left turntable 5 to control the operation of the left expansion component. The telescopic part of the electric push rod 201 contracts, driving the round block 202 and the five connecting rods 203 to move to the right. During the movement, the five connecting rods 203 will push the five sliding columns 6 on the left to move to the outside of the turntable 5 in the linear slide 5001. During this process, the connecting rod 203 adaptively rotates around the connection point with the round block 202 and the sliding column 6. , and when the five slide posts 6 on the left turntable 5 are in contact with the inner ring surface of the small circular ring 10, the five slide posts 6 on the left turntable 5 tightly fix the small circular ring 10, that is, at this time, the small circular ring 10 is tightly clamped on the five slide posts 6 on the left, and at this time, as the telescopic part of the left electric push rod 1 201 continues to drive the round block 202 and the five connecting rods 203 to move to the right, the spring telescopic column 204 on the left connecting rod 203 will be forced to compress, and then the large circular ring 11 will be placed on the several slide posts 6 of the right turntable 5, and the small circular ring 10 will be close to the left side of the right turntable 5, and then the right expansion component will be controlled to run, and the five slide posts 6 on the right will slide in the linear slide groove 5001 to clamp the large circular ring 11; Next, the two power components are controlled to operate synchronously. Taking the power component on the left as an example, the electric slider 102 moves to the right on the electric slide rail 101. The two electric sliders 102 drive the mounting plate 103, the motor 104, the disc 3, the cylinder 4, the turntable 5, the expansion component, the slide column 6, the cone 7, the receiving plate 8, the push block 9 and the suction component to move to the right together, and the small ring 10 is moved to the specified position. At the same time, the power component on the right also operates synchronously, and the large ring 11 is also moved to the specified position. Then, the two suction components are controlled to operate synchronously. Taking the suction component on the left as an example, the external air pump is controlled to start Start, and transport gas into the annular hollow tube 303 through the vertical pipe 305. The gas enters the receiving plate 8 through the connecting pipe 302, and the plurality of push blocks 9 are connected to the inside of the receiving plate 8, and the gas will also enter the plurality of push blocks 9. With the continuous transportation of gas, the air pressure in the receiving plate 8 gradually increases, which will push all the push blocks 9 to move outward on the receiving plate 8. After all the push blocks 9 move to the outermost side of the receiving plate 8, the air pump is controlled to stop transporting gas, and the suction component on the right also runs synchronously under the action of the air pump, so that the plurality of push blocks 9 on the right receiving plate 8 move to the outermost side; At the same time, the telescopic parts of the four electric push rods 3 405 are controlled to be pushed out, driving the two arc rings 2 406 to move forward, and the two arc rings 2 406 are moved to the specified position, and then the output shafts of the two motors 104 are controlled to rotate clockwise, driving the disc 3, the cylinder 4, the turntable 5, the expansion assembly, the sliding column 6, the cone 7, the receiving plate 8, the push block 9, the sealing ring 301, the connecting pipe 302, the annular hollow tube 303, the small circular ring 10, the large circular ring 11 and the placed rectangular rod 12 to rotate clockwise together. At this time, the operator places the twelve rectangular rods 12 on the top of the two receiving plates 8 in sequence, that is, the twelve rectangular rods 12 are placed in the slots 9001 of the two push blocks 9 on the same axis in sequence, and controls the external welding robot to weld the connection between the small circular ring 10, the large circular ring 11 and the rectangular rod 12, until the small circular ring 10, the large circular ring 11 and all the rectangular rods 12 are welded together, and then the output shafts of the two motors 104 are controlled to stop rotating, as shown in FIG. Figure 8 As shown, in this way, the small circular ring 10, the large circular ring 11 and the rectangular rod 12 are manually placed on the device, and the device is used to fix them. When necessary, the small circular ring 10, the large circular ring 11 and the rectangular rod 12 are driven to rotate, and then the external welding robot is controlled to automatically weld the spliced ​​round table tripod 1, so that the production of the round table tripod 1 is replaced by the automatic device instead of the manual production. This not only improves the production efficiency of the round table tripod 1, saves a lot of manpower, and is different from manual welding, but also reduces the number of defective products in the production process of the round table tripod 1; When the rectangular rod 12 rotates from the upper part of the receiving plate 8 to the lower part of the receiving plate 8, it will contact the two arc rings 406. The two arc rings 406 restrict the rotating rectangular rod 12 to prevent the rectangular rod 12 from being separated from the small ring 10 and the large ring 11 during the rotation, thereby affecting the welding quality.

[0031] When the welding of the round table tripod is completed, the external air pump is controlled to extract the gas in the receiving plate 8 through the vertical pipe 305, the annular hollow pipe 303 and the connecting pipe 302, so that all the push blocks 9 move toward the center of the receiving plate 8, so that all the push blocks 9 are separated from the rectangular rod 12, and then the telescopic parts of the two electric push rods 201 are controlled to be pushed out, driving the connected parts to move, so that all the slide columns 6 move toward the center of the turntable 5 in the linear slide groove 5001, and no longer clamp the small circular ring 10 and the large circular ring 11, and then the two power components are controlled to run synchronously, driving the connected parts to reset and move away from the welded round table tripod. At this time, the two arc rings 406 are below the welded round table tripod, and the welded round table tripod is supported by the two arc rings 406. After the operator takes away the welded round table tripod, the telescopic parts of all the electric push rods 405 are controlled to shrink, driving the connected parts to reset.

[0032] When welding the round table tripod two, the operator first places the two small rings 10 on the left and right sliding columns 6 respectively, and the small rings 10 are fitted with the sides of the turntable 5, and then controls the two expansion components to operate, driving a number of sliding columns 6 to move around on the turntable 5 to clamp the two small rings 10, and then controls the two power components to operate synchronously, and drives the connected components and the two small rings 10 to move to opposite sides through the electric slider 102. After the two small rings 10 move to the specified position, that is, just the spacing of the round rods 13, the electric slider 102 is controlled to stop moving, and then the output shafts of the two motors 104 are controlled to rotate clockwise. The operator places all the round rods 13 in the grooves 8001 of the two receiving plates 8 on the same axis in turn, and then controls the external welding robot to weld the connection between the two small rings 10 and the placed round rods 13. After the two small rings 10 and all the round rods 13 are welded together, the output shafts of the two motors 104 are controlled to stop rotating. Fig. 9 As shown, two small circular rings 10 and all round rods 13 are manually placed on the device, and the device is used to fix them. When necessary, the small circular rings 10 and all round rods 13 are driven to rotate, and then the external welding robot is controlled to automatically weld the spliced ​​round table tripod two, so that the production of the round table tripod two is replaced by the automatic device instead of the manual production. This not only improves the production efficiency of the round table tripod two, saves a lot of manpower, and is different from manual welding, but also reduces the number of defective products in the production process of the round table tripod two; During the process of the round rod 13 rotating from the upper part of the receiving plate 8 to the lower part of the receiving plate 8, it will also contact the two arc rings 404. The two arc rings 404 restrict the rotating round rod 13 to prevent the round rod 13 from detaching from the small ring 10 during the rotation process, affecting the welding quality of the subsequent welding assembly.

[0033] When the welding of the round table tripod two is completed, the telescopic parts of the two electric push rods 201 are controlled to be pushed out, driving the connected parts to move, allowing all the slide columns 6 to move toward the center of the turntable 5 in the linear slide groove 5001, and no longer clamping the two small circular rings 10, and then the two power components are controlled to run synchronously to drive the connected parts to reset, so that the welded round table tripod two is separated from the two receiving plates 8. At this time, the two arc rings 404 are located below the welded round table tripod two, and the welded round table tripod two is supported by the two arc rings 404. After the operator takes away the welded round table tripod two, the telescopic parts of all the electric push rods 402 are controlled to shrink, driving the connected parts to reset.

[0034] It should be noted that the device can adapt to two different round table tripods. When necessary, there is no need to modify the device or replace accessories. The production type can be switched at will, achieving an integrated multi-purpose effect and greatly saving production costs.

When one end of the rectangular rod 12 and the round rod 13 is slightly bent, the operator cannot put the rectangular rod 12 or the round rod 13 into the groove 8001 or the slot 9001. The bent rectangular rod 12 or the round rod 13 needs to be replaced with a new one or manually corrected with a correction device before it can be put into the groove 8001 or the slot 9001. This takes a long time and has low work efficiency. Therefore, when the operator fixes the two small rings 10 and finds that one end of one of the round rods 13 is slightly bent to the left or right during the process of placing the round rods 13 and cannot be placed in the groove 8001, the operator manually grabs the slide plate 82 or the positioning block 83 that receives the round rod 13 and slides it in the arc-shaped slide groove 8002, so that the slide plate 82 or the positioning block 83 moves in the direction of the bending of the round rod 13, and forces the elastic cloth 84 to stretch accordingly, so that the slightly bent round rod 13 can be placed in the slide plate 82 or the positioning block 83. The first limit block 502 and the second limit block 503 are placed in the groove 8001 of the block 83. After the round rod 13 is placed on the slide plate 82 or the positioning block 83 in the arc-shaped slide groove 8002, the telescopic parts of the two electric push rods 504 are controlled to contract, driving the slide bar 501, the limit block 1 502, the limit block 2 503 and the arc block 505 to move toward the center of the cone 7. During the movement, the four limit blocks 1 502 and the two limit blocks 2 503 will contact the three slide plates 82 and the four positioning blocks 83, forcing the three slide plates 82 and the four positioning blocks 83 to move in the arc-shaped slide groove 8002. The bent round rod 13 is corrected by sliding three slide groove plates 82 and four positioning blocks 83 until the four limit blocks 1 502 and the two limit blocks 2 503 contact the outer surface of the shell 81. The three slide groove plates 82 and the four positioning blocks 83 in the arc-shaped slide groove 8002 will automatically restore to completely correct the bent round rod 13, making it convenient for the subsequent welding robot to weld it on the two small rings 10. In this way, the operator does not need to replace the slightly bent round rod 13, which saves a lot of time and improves work efficiency.

[0039] When one end of the round rod 13 is slightly bent upward or downward, one end of the round rod 13 can be placed in the groove 8001 of the slide plate 82 or the positioning block 83, and only half of the other end of the round rod 13 is in the groove 8001 of the slide plate 82 or the positioning block 83. At this time, if the round rod 13 is rotated to the welding position and welded by a welding robot, the welding of the round rod 13 at this position will cause non-standard welding of the round rod 13, thereby affecting the quality of the entire round table tripod. When the round rod 13 is rotating, one end of it is tilted upward, it will be restricted by the two arc rings 404. While preventing it from falling off, the tilted end of the round rod 13 is squeezed back into the groove 8001 of the slide plate 82 or the positioning block 83, so that the round rod 13 remains in a normal state until it is rotated to the welding position for welding, thereby ensuring the welding quality of the round rod 13.

[0040] When all the round rods 13 are welded to the two small circular rings 10, the telescopic parts of all the electric push rods 504 are controlled to be pushed out, driving the connected parts to move, and no longer restricting the slide plate 82 and the positioning block 83, so that it is convenient for the subsequent manual placement of the bent round rods 13 in the grooves 8001 of the slide plate 82 and the positioning block 83.

[0041] It should be noted that the bending correction steps of the rectangular rod 12 can be carried out by referring to the bending correction steps of the round rod 13 , so that the bent rectangular rod 12 can be restored and welded to the small circular ring 10 and the large circular ring 11 .

[0042] Since the welding robot will generate a large amount of smoke during the welding process, and the smoke diffuses in the air, it will cause air pollution, and artificial inhalation of a large amount of polluted air will endanger the health of the human body. Therefore, when the welding robot is working, the external exhaust device is controlled to open, and the gas in the hollow arc ring 1 404 and the arc ring 2 406 is extracted through the air intake pipe 1 40401 and the air intake pipe 2 40601, so that the several circular holes 1 40402 of the arc ring 1 404 and the several circular holes 2 40602 of the arc ring 2 406 are Suction is generated. At this time, because arc ring 1 404 and arc ring 2 406 play a limiting and supporting role when welding round table leg 1 and round table leg 2, and are located not far from the welding position, when the welding robot is welding, suction is generated through several circular holes 1 40402 and several circular holes 2 40602 to remove the fume generated by the welding robot during welding work, so as to perform environmentally friendly welding operations and avoid a large amount of fume generated by continuous welding work from escaping into the air, causing air pollution and affecting the health of the workers.
