[0002] Street lights refer to lamps that provide lighting functions for roads, and generally refer to lamps within the scope of road lighting in traffic lighting. Street lights are widely used in various places where lighting is required. The higher street light pole connectors require a circular sleeve-shaped fixing part combined with a flange to achieve a split fixed connection of multiple street light pole connectors, so the circular sleeve-shaped connecting part and the flange need to be welded and fixed; An automatic welding production line device for street lamp pole flanges described in a patent application with announcement number CN217551513U relates to the technical field of welding equipment manufacturing, and includes a frame and a welding gun.

[0003] At present, when welding the cylindrical lamp pole connector of the connector type to the inner wall of the flange, manual welding is usually used, which is inefficient. During automatic welding, a large amount of metal particles and impurities in the workshop will adhere to the flange and the lamp pole connector due to transportation on the production line, resulting in a large number of impurity particles at the junction welding between the flange and the lamp pole connector, affecting the welding quality of subsequent automatic welding. Summary of the invention

[0006] Preferably, a threaded column is fixedly connected to the bottom of the fixed disk, a sliding sleeve is threadedly connected to the outer wall of the threaded column, a square groove is formed on the outer wall of the sliding sleeve, and the fixed disk is electrically connected to the sliding block.

[0007] Preferably, a correction head is fixedly connected to the bottom of the sliding sleeve, and the correction head is a truncated cone structure. A spring A is fixedly connected to the top of the sliding sleeve, and the top of the spring A is fixedly connected to the bottom of the fixed disk.

[0008] Preferably, the thread lead angle between the outer wall of the threaded column and the inner wall of the sliding sleeve is greater than forty-five degrees, and the outer wall of the sliding sleeve is fixedly connected to a fixing plate.

[0009] Preferably, a telescopic rod A is fixedly connected to the bottom of the fixed plate, and a push plate A is fixedly connected to the bottom of the telescopic rod A.

[0010] Preferably, a rubber block is fixedly connected to the bottom of the push plate A, a spring B is fixedly connected to the top of the push plate A, and the top of the spring B is fixedly connected to the bottom of the fixed plate.

[0011] Preferably, an auxiliary mechanism is provided at the bottom of the fixed plate, and the auxiliary mechanism includes a second sliding block, the top of the second sliding block is slidably connected to the bottom of the fixed ring, the outer wall of the second sliding block is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to the bottom of the sliding block, and the bottom of the second sliding block is hinged with a telescopic rod B through a hinge block.

[0012] Preferably, one end of the telescopic rod B is hinged to a push plate B through another hinge block, and one side of the push plate B is fixedly connected to a brush strip.

[0013] The present invention provides an automatic welding production line for street lamp pole flanges, which has the following beneficial effects: 1. The present invention sets a welding mechanism. As the elevator pushes the lifting block down, the fixed plate is driven down. When welding with the welding head, the correction head will first be inserted into the middle of the lamp pole connecting part, and the inclined surface of the outer wall of the correction head will push the inner wall of the lamp pole connecting part to align the lamp pole connecting part and the flange below, so that the lamp pole connecting part and the flange are centered at the center position of the correction head and the sliding sleeve, maintaining the same center of the circle. Therefore, when the subsequent welding head descends to the specified position, precise automatic welding can be performed on the fixed ring to prevent the misalignment problem caused by automatic rotation welding.

[0014] 2. The present invention sets a welding mechanism to centrifugally rotate the metal particles and impurities on the outer wall of the lamp pole connector to be welded, and throw them off the sliding sleeve. After that, as the threaded column is completely immersed in the sliding sleeve, the welding head stops descending until it descends to the designated welding point. The spring A deforms to keep the sliding sleeve pushing the push plate A to squeeze the lamp pole connector, thereby realizing fully automatic and stable rotation welding. At the same time, the process of clamping and tightening the flange is simultaneously used to throw off the metal particles and impurities on the outer wall of the flange and the lamp pole connector, thereby avoiding the influence of impurities on the welding accuracy and stability of the annular welding and improving the welding quality.

[0015] 3. The present invention sets up a welding mechanism, which can not only rotate to throw out the granular impurities, but also continuously rub against the brush bar to sweep out the remaining particles between the flange and the lamp pole connector. At the same time, the inner wall of the lamp pole connector and the flange rotate in real time, so that the swept particles and impurities are thrown outward and away from the part to be welded, thereby reducing the problems of welding accuracy and quality degradation.

[0016] 4. The present invention sets a welding mechanism. As the hinge block continues to descend, the push plate B is pushed close to the flange by the hinge, thereby pressing against the flange. The telescopic rod B is pushed to contract by the hinge, so that the built-in spring in the telescopic rod B is compressed, so that the push plate B maintains the position of the junction of the flange and the lamp pole connector through the brush strip, thereby maintaining the cleaning force on the flange.

[0017] 5. The present invention sets a welding mechanism so that when it contacts the brush strip on the push plate B, it will not be deformed. At the same time, the push plate B absorbs heat and cools the welding position, and the brush strip sweeps away the welding slag at the welding position. After the welding is completed, when the fixed plate is lifted, the elastic force of the spring A pushes the sliding sleeve and the threaded column apart, so that the sliding sleeve drives the flange and the lamp pole connector to rotate again, and the cleaned welding slag is automatically thrown away by the centrifuge, thereby completing the automatic cleaning of the welding slag after welding and the real-time cooling of the welding position.

DETAILED DESCRIPTION

[0020] Example 1: Please refer to Figure 1-4The present invention provides a technical solution: an automatic welding production line for a street lamp pole flange, comprising a welding production line 1, a conveyor chain 5 is arranged in the welding production line 1, a fixed platform 2 is fixedly connected to the top of the welding production line 1, a lifter 7 is fixedly connected to the top of the fixed platform 2, a lifting block 8 is fixedly connected to the output end of the lifter 7, a placing platform 6 is fixedly connected to one side of the lifting block 8, a bearing plate 9 is fixedly connected to the top of the placing platform 6, and a welding mechanism 3 is arranged above the bearing plate 9; The welding mechanism 3 comprises: A fixed plate 301, the top of the fixed plate 301 is fixedly connected to the bottom of the lifting block 8, a fixed ring 302 is fixedly connected to the bottom of the fixed plate 301, the fixed plate 301 is a circular plate-shaped structure, the fixed ring 302 is an annular plate-shaped structure, a sliding block 303 is slidably connected to the bottom of the fixed ring 302, and the fixed plate 301 is used to control the sliding block 303 to make it slide and rotate on the fixed ring 302; The welding head 304 is L-shaped, the top of the welding head 304 is fixedly connected to the bottom of the sliding block 303, and the welding head 304 is used to be driven by the sliding block 303 to perform a circular motion to weld the junction between the flange and the lamp pole connector.

[0021] When in use, the lamp pole connector of the street lamp is put on the flange and then placed on the bearing plate 9. The conveyor chain 5 is controlled by starting the welding production line 1 to move the placement table 6 to the bottom of the fixed table 2, and then the lifting block 8 is controlled by the lift 7 to lift and lower, so that the welding head 304 under the lifting block 8 is aligned with the interface between the flange and the lamp pole connector. Then, the fixed plate 301 is started to control the sliding block 303 on the fixed ring 302 to rotate on the fixed ring 302, so that the welding head 304 performs a slow welding method of rotating and welding, thereby completing the automatic welding of the lamp pole connector and the flange. Example 2: Please refer to Figure 1-13 On the basis of the first embodiment, the present invention provides a technical solution, wherein a threaded column 305 is fixedly connected to the bottom of the fixed disk 301, a sliding sleeve 306 is threadedly connected to the outer wall of the threaded column 305, a square groove is provided on the outer wall of the sliding sleeve 306, and the fixed disk 301 is electrically connected to the sliding block 303.

[0022] A correction head 308 is fixedly connected to the bottom of the sliding sleeve 306 , and the correction head 308 is a truncated cone structure. A spring A307 is fixedly connected to the top of the sliding sleeve 306 , and the top of the spring A307 is fixedly connected to the bottom of the fixed disk 301 .

[0023] The thread lead angle between the outer wall of the threaded column 305 and the inner wall of the sliding sleeve 306 is greater than forty-five degrees, and the outer wall of the sliding sleeve 306 is fixedly connected to a fixing plate 309 .

[0024] A telescopic rod A310 is fixedly connected to the bottom of the fixed plate 309, and a push plate A311 is fixedly connected to the bottom of the telescopic rod A310.

[0025] A rubber block 313 is fixedly connected to the bottom of the push plate A311 , a spring B312 is fixedly connected to the top of the push plate A311 , and the top of the spring B312 is fixedly connected to the bottom of the fixed plate 309 .

[0026] The bottom of the placement table 6 and the conveyor chain 5 are supported by the horizontal plate in the welding production line 1, so they will not sink or shake during welding, but at the same time the conveyor chain 5 can drive the placement table 6 to move and convey the objects above; As the lifter 7 pushes the lift block 8 down and drives the fixed plate 301 down, when the welding head 304 is used for welding, the correction head 308 will first be inserted into the middle of the lamp pole connector, and the inclined surface of the outer wall of the correction head 308 will push the inner wall of the lamp pole connector to align the lamp pole connector with the flange below, so that the lamp pole connector and the flange are centered at the center of the correction head 308 and the sliding sleeve 306, and the same center is maintained. Therefore, when the subsequent welding head 304 is lowered to the specified position, it can automatically rotate on the fixing ring 302 for accurate automatic welding, thereby preventing the misalignment problem in automatic rotation welding; After the correction head 308 is inserted into the lamp pole connector, as the fixed plate 301 continues to descend, the correction head 308 will abut against the bearing plate 9 below. As the fixed plate 301 pushes the threaded column 305 to continue to descend, the correction head 308 cannot move at this time, so the threaded column 305 will slide and descend on the inner wall of the sliding sleeve 306. The outer wall of the threaded column 305 is threadedly connected to the inner wall of the sliding sleeve 306 through a thread. The lead angle of the thread is greater than 45 degrees, so the friction force of rotation is small. Therefore, when the threaded column 305 descends vertically on the inner wall of the sliding sleeve 306, the sliding sleeve 306 will rotate. When the correction head 308 and the sliding sleeve 306 enter the inner wall of the lamp pole connector, the lamp pole connector and the flange position will be pushed into alignment through the inclined surface of the correction head 308, and then the push plate A311 will start to contact with the edge of the top of the lamp pole connector. As the correction head 308 continues to descend and pushes the sliding sleeve 306 to start rotating using the thread, it will also drive the fixed plate 309, the telescopic rod A310 and the push plate A311 to rotate synchronously. The push plate A311 uses the rubber block 313 with greater friction at the bottom to firmly fix the lamp pole connector, so that the lamp pole connector is pressed and rotates synchronously with the rotation of the sliding sleeve 306. When the threaded column 305 quickly enters the sliding sleeve 306, it will drive the sliding sleeve 309 to rotate synchronously. 6 is rotated rapidly, so that the inner wall of the lamp pole connector and the bearing plate 9 at the bottom are also rotated at the same time, and the metal particles and impurities on the outer wall of the lamp pole connector that are about to be welded are centrifugally rotated and thrown away from the sliding sleeve 306. After that, as the threaded column 305 is completely immersed in the sliding sleeve 306, the welding head 304 stops descending until it descends to the designated welding point. The spring A307 deforms to keep the sliding sleeve 306 pushing the push plate A311 to squeeze the lamp pole connector, realizing full-automatic stable rotation welding. At the same time, the process of clamping and tightening the flange is also used to simultaneously throw away the metal particles and impurities on the flange and the outer wall of the lamp pole connector, avoiding the influence of impurities on the welding accuracy and stability of the annular welding, and also improving the welding quality. The push plate A311 maintains the pressing effect on the top of the lamp pole connector by the deformation of the spring B312. The telescopic rod A310 can be telescoped after the sliding sleeve 306 enters the inner wall of the lamp pole connector and the push plate A311 can be lifted and lowered in the vertical direction. Example 3: Please refer to Figure 1-16 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution, an auxiliary mechanism 4 is provided at the bottom of the fixed disk 301, the auxiliary mechanism 4 includes a second sliding block 406, the top of the second sliding block 406 is slidably connected to the bottom of the fixed ring 302, the outer wall of the second sliding block 406 is fixedly connected to a connecting rod 401, one end of the connecting rod 401 is fixedly connected to the bottom of the sliding block 303, and the bottom of the second sliding block 406 is hinged with a telescopic rod B403 through a hinge block 402.

[0027] One end of the telescopic rod B403 is hinged to a push plate B404 through another hinge block 402, and one side of the push plate B404 is fixedly connected to a brush strip 405.

[0028] When the push plate A311 presses against the lamp pole connector and drives the lamp pole connector to rotate through the bearing plate 9 below, the right angle position where the lamp pole connector and the flange meet will continuously contact the brush strip 405 on the push plate B404 as it rotates, and while rotating to throw out the particle impurities, the swept particles and impurities are also thrown out while the inner wall of the lamp pole connector and the flange rotate in real time, so as to keep them away from the part to be welded, thereby reducing the problem of welding accuracy and quality degradation; When the fixed plate 301 descends, the fixed ring 302 and the second sliding block 406 are driven to descend synchronously, and the hinge block 402, the telescopic rod B403 and the push plate B404 are pushed down, and the push plate B404 contacts the surface of the flange, and as the hinge block 402 continues to descend, the push plate B404 is pushed close to the flange by the hinge, so as to resist the flange, and the telescopic rod B403 is pushed to shrink by the hinge, so that the built-in spring in the telescopic rod B403 is compressed, so that the push plate B404 maintains the position of pushing the junction of the flange and the lamp pole connector through the brush strip 405, and maintains the cleaning force on the flange; A torsion spring is arranged in the hinge block 402 at the top of the telescopic rod B403. The torsion spring will make the telescopic rod B403 not be in a vertical state when the telescopic rod B403 and the push plate B404 are lowered by gravity, but keep a certain angle toward the sliding sleeve 306. Therefore, when the push plate B404 descends and contacts the lowered flange, the telescopic rod B403 and the push plate B404 will be pushed to move toward the flange and the lamp pole connection piece through the hinge block 402 as the fixed plate 301 descends. After the fixed disk 301 descends and pushes the welding head 304 to the specified position and stops, the push plate A311 keeps pushing the flange, and as the sliding block 303 drives the welding head 304 to rotate circumferentially on the fixed ring 302 for welding, the connecting rod 401 moves synchronously with the hinge block 402, so that when the welding head 304 rotates while welding, the push plate B404 also keeps rotating while cleaning and wiping, and after the welding head 304 rotates and welds one circle and returns to its original position, the push plate B404 will also clean the position after welding and cool it down, and the push plate B404 is located opposite to the welding head 304, and the welding head 304 will not contact the push plate until it rotates half a circle after welding. The push plate 301 contacts the push plate B404, so that there is enough time for the welding position to harden and cool, and when it contacts the brush strip 405 on the push plate B404, it will not deform. At the same time, the welding position is also cooled by the push plate B404, and the welding slag at the welding position is swept away by the brush strip 405. After the welding is completed, when the fixed plate 301 is lifted, the elastic force of the spring A307 pushes the sliding sleeve 306 and the threaded column 305 apart, so that the sliding sleeve 306 drives the flange and the lamp pole connector to rotate again, and the cleaned welding slag is automatically thrown away with the centrifugal force, thereby completing the automatic cleaning of the welding slag after welding and the real-time cooling of the welding position; After the welding is completed, the conveyor chain 5 is controlled by starting the welding production line 1 to convey the placement tables 6 in the two conveyor chains 5 to the next processing position, so as to perform automatic welding of the street lamp pole connector and the flange.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
