[0019] Example:

[0020] See also Figure 1-Figure 8 The present invention provides a technical solution: a water receiving tray welding positioning device for 6G water purifier processing, comprising: The operating body 1 includes a chassis 11, a positioning plate 12 that fits the outer surface of the outer bottom shell is fixedly connected to the top of the chassis 11, and a tooling seat 13 that can be used to place the external support legs is rotatably connected to the chassis 11 through a mounting hole 111 provided inside the chassis 11; The lifting part 2 includes a lifting rod 21, the top of which is fixedly connected to a lifting plate 22 that fits the lower surface of the outer bottom shell, and the top of the inner wall of the chassis 11 is fixedly connected to a sleeve 23 that slides on the outer surface of the lifting rod 21. The bottom of the chassis 11 is provided with a correction piece 3 that can be used to adjust the position of the lifting rod 21; A placement hole 131 that fits with the external support leg is opened on the upper surface of the tooling seat 13 , and a laser generator 4 is nested and installed inside the tooling seat 13 .

[0021] The outer surface of the positioning plate 12 is designed as a curved surface, and a tooth plate 132 is fixedly connected to the bottom of the tooling seat 13 .

[0022] The teeth of multiple sets of tooth plates 132 are meshed with a rack 133, and the top of the inner wall of the chassis 11 is fixedly connected to a servo unit 112 which is transmission-connected to the rack 133 through a bracket. The bottom end of the lifting rod 21 adopts a conical design, and the bottom end of the lifting rod 21 passes through the chassis 11 and extends to the outside.

[0023] A return spring 231 is fixedly connected to the bottom of the inner wall of the sleeve 23 . The return spring 231 is sleeved on the outer circumferential surface of the lifting rod 21 . The top of the return spring 231 is fixedly connected to the lower surface of the lifting plate 22 . A semicircular groove 211 is opened on the outer circumferential surface of the lifting rod 21 .

[0024] The correction part 3 includes an external block 31, the top of the external block 31 is fixedly connected to the bottom of the chassis 11, the external block 31 is slidably connected to a slider 33 through a slide rail 32 opened inside it, the outer surface of the slider 33 is provided with a strong spring 34 connected to the inside of the external block 31, the inside of the slider 33 is rotatably connected to an adjustment rod 35, and the outer surface of the circumference of the adjustment rod 35 is sleeved with a clamping rod 36 that fits with the inner wall of the semicircular clamping groove 211.

[0025] The central axis of the adjusting rod 35 does not coincide with the central axis of the clamping rod 36 . The adjusting rod 35 is slidably connected to a smooth rod 37 through a sliding hole provided inside the adjusting rod 35 . A counterweight ball 38 is fixedly connected to the outer end of the smooth rod 37 .

[0026] refer to Figure 1-8 Some vertical water trays are equipped with support legs to support the weight of the entire water tray and maintain stability. The bottom shell and the support legs are usually fixed by welding, which requires workers to hold a welding gun for welding. Since the support leg welding lacks positioning tooling (marking is used for positioning), the support legs are offset during the welding process. At the same time, there are four groups of support legs, which require workers to weld one by one, resulting in low overall efficiency and unfavorable to the automated production rhythm. In order to overcome the above-mentioned defects, the present invention designs a water receiving tray welding positioning device for 6G water purifier processing.

[0027] The bottom shell and supporting legs are loaded separately (including positioning adjustment): Initially, the worker places the supporting legs to be welded in the placement holes 131 of the tooling seat 13. The inner wall of the placement holes 131 fits tightly against the outer surface of the supporting legs, which can accommodate four groups of supporting legs at one time, and the tops of the supporting legs are slightly higher than the laser generator 4. Working principle of the laser generator 4: In the laser welding process, the laser is used as a heat source. The principle is to convert the laser beam into a laser beam through a converter, and then irradiate it on the surface of the workpiece to be welded. When the laser beam contacts the surface of the workpiece, a high-energy heat source is generated and the surface is melted, which is different from conventional "filler welding". Therefore, laser welding requires the welded parts to fit tightly together. Generally, a clamp is used to apply pressure to fit the two welded parts together (the present invention uses the gravity of the bottom shell to fit it tightly against the top of the supporting leg). The tight fit of the welded parts can ensure the welding quality. Next, slide the bottom shell downward along the arc surface of the positioning plate 12 (the arc surface makes it easy to quickly put the bottom shell in). The bottom shell slides downward along the outer surface of the positioning plate 12 due to its own gravity. The positioning plate 12 can limit its four sides. The bottom shell falls to the upper surface of the lifting plate 22 of the lifting part 2. The upper surface of the lifting plate 22 fits with the lower surface of the bottom shell, and the bottom shell is corrected to be horizontal to ensure that during subsequent welding, the lower surface of the bottom shell can fit tightly with the four sets of support legs to be welded.

[0028] Next, the bottom shell is pressed downward manually, driving the bottom shell to slide downward along the outer surface of the positioning plate 12, driving the lifting plate 22 to slide downward (the return spring 231 is further compressed to undergo elastic deformation), driving the lifting rod 21 to slide downward along the inside of the sleeve 23, and the bottom end of the lifting rod 21 passes through the chassis 11 and slides downward. The bottom end of the lifting rod 21 adopts a conical design, and the bottom end of the lifting rod 21 slides into between the adjacent clamping rods 36 of the correction member 3, and generates a thrust on the clamping rod 36, driving the two groups of clamping rods 36 to separate from each other, driving the slider 33 to slide along the inner wall of the external block 31, and the strong spring 34 undergoes elastic deformation until the lower surface of the bottom shell contacts the support legs to be welded. At this time, the two groups of clamping rods 36 are respectively clamped into the corresponding semicircular clamping grooves 211, and then the two groups of clamping rods 36 limit the lifting rod 21, which is convenient for rapid welding of the bottom shell and the four groups of support legs to be welded.

[0029] The present application needs to emphasize that, in order to facilitate the rapid combination of the two groups of clamping rods 36 and the semicircular clamping grooves 211, initially, the smooth rod 37 on the correction member 3 is subjected to the force of the counterweight ball 38, and the smooth rod 37 is in an "outward tilt state", driving the adjustment rod 35 to rotate around the inside of the slider 33, driving the clamping rod 36 to rotate upward (the central axis of the adjustment rod 35 does not coincide with the central axis of the clamping rod 36), and after the clamping rod 36 is displaced upward for a short distance, the lifting rod 21 moving downward can make the clamping rod 36 quickly combine with the semicircular clamping groove 211. At the same time, the bottom shell that is released from the pressing is subjected to the elastic force of the reset spring 231, driving the lifting rod 21 to "extremely short displacement" upward along the inside of the sleeve 23, driving the lifting plate 22 and the bottom shell to "extremely short displacement" synchronously upward, and then the clamping rod 36 limits it. The bottom shell that is "extremely short displacement" upward will form a certain gap between the supporting leg to be welded, which cannot meet the requirements of laser welding. The present application can further correct the position of the bottom shell to ensure that the bottom shell and the supporting leg to be welded fit tightly. Manually pull the smooth rod 37 to slide along the inside of the adjusting rod 35. Using the "lever principle", the counterweight ball 38 drives the smooth rod 37 from the "outward tilted state" to the "inward tilted state", driving the adjusting rod 35 to rotate around the inside of the slider 33, and driving the clamping rod 36 to rotate downward in line with the inner wall of the semicircular clamping groove 211 (the central axis of the adjusting rod 35 does not coincide with the central axis of the clamping rod 36). The clamping rod 36 drives the lifting rod 21 to move downward a short distance until the upper surface of the lifting plate 22 is lower than the upper end of the supporting leg. At this time, the bottom shell is affected by its own gravity, and the lower surface of the bottom shell is tightly fitted with the upper end of the supporting leg to be welded, completing the correction.

[0030] The bottom shell and the supporting legs are welded uniformly: When the lower surface of the bottom shell is tightly fitted with the upper end of the supporting leg to be welded, the servo unit 112 is started, and its output end drives the rack 133 for conveying, driving the toothed plate 132 to rotate, driving the four groups of tooling seats 13 to rotate synchronously around the inside of the chassis 11, driving the four groups of laser generators 4 to rotate synchronously, and the emitting unit of the laser generator 4 rotates in a circle along the junction of the bottom shell and the supporting leg. Then the laser generator 4 is started, and the four groups of supporting legs can be welded synchronously. At the same time, the bottom shell and the four groups of supporting legs have been automatically calibrated in advance, which greatly improves the welding accuracy and speed.

[0031] Synchronous cutting of the bottom shell and the supporting legs: When the four groups of supporting legs are welded to the bottom shell, in order to facilitate the rapid removal of the welded bottom shell, the present application can be quickly achieved with the help of the lifting rod 21 and the reset spring 231. The adjusting rod 35 is pulled outward with both hands to quickly separate, driving the slider 33 to slide along the inner wall of the slide rail 32, driving the clamping rod 36 to quickly disengage from the semicircular clamping groove 211, and the limit on the lifting rod 21 disappears. The lifting rod 21 is acted upon by the elastic force of the reset spring 231, driving the lifting plate 22 and the welded bottom shell to move rapidly upward until the welded bottom shell is separated from the positioning plate 12, and then it can be quickly removed and the next group of welding can be carried out.
