[0002] like Figure 15 As shown, the scraper conveyor chain includes chain links and scrapers. The scrapers are symmetrically welded to one end of each chain link. Currently, welding is mainly done manually. To improve efficiency, operators often weld directly without fixing the scrapers, leading to deformation during welding and resulting in significant deviations in the final dimensional position of the scrapers, affecting practical use. Furthermore, the conventional fixing method is an elbow clamp, which is inconvenient to operate. Since the scrapers need to be welded on both sides, after ordinary welding, the chain links and scrapers need to be manually flipped and then re-fixed to prevent welding deformation. The existing manual welding method is generally inefficient and inconsistent. Utility Model Content

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 15 As shown, a scraper conveyor chain welding device includes a positioner 1, a welding base plate 2, positioning pins 4, a clamping device 3, and a positioning device 6. The positioner 1 is equipped with a rotating frame 11, which is a frame structure. The welding base plate 2 is fixed on the rotating frame 11 and has several welding grooves 21. The positioning pins 4 are fixed on the welding base plate 2 and are arranged along one side of the scraper 92. The positioning pins 4 are used to position the scraper 92. The clamping device 3 and the positioning device 6 are both fixed on the welding base plate 2, and the clamping device 3 is located on both sides of the positioning device 6 to clamp the scraper 92 on both sides. The positioning device 6 is located on one side of the welding grooves 21 and is used to position the chain links 91 so that the scraper 92 is symmetrically located on both sides of the chain links 91.

[0031] The positioning device 6 positions the chain link 91, and then the scraper 92 is positioned on both sides of the chain link 91 by the positioning pin 4. The scraper 92 is then fixed by the clamping device 3. The position of the scraper 92 will not change during welding. After one side of the scraper 92 is welded, the positioner 1 flips the welding base plate 2 so that the other side of the scraper 92 faces upward. The other side of the scraper 92 is then welded through the welding groove 21. Welding can be completed in one clamping, which greatly reduces the clamping time and improves the welding efficiency. In addition, the scraper 92 can be effectively fixed and positioned throughout the welding process, which effectively reduces the impact of welding, improves the consistency of the finished product, and improves the quality of the product.

[0032] The positioning device 6 is provided with two clamping devices 3 on both sides. The two clamping devices 3 are fixed from both ends of the scraper 92, so that the scraper 92 is not easily deformed.

[0033] To facilitate the fixing of the positioning pin 4, the welding base plate 2 is provided with several first fixing holes 22. The first fixing holes 22 are stepped holes. The positioning pin 4 is inserted into the shoulder of the hole inside the first fixing hole 22. The bottom of the positioning pin 4 is provided with a threaded hole. The positioning screw is inserted into the first fixing hole 22 and connected to the threaded hole. The positioning screw fixes the positioning pin 4 and prevents the positioning pin 4 from falling off.

[0034] The positioning device 6 includes a fixed positioning seat 65, a movable positioning seat 61, a connecting pin 62, a connecting positioning seat 64, and a positioning pin 66. The fixed positioning seat 65 is installed at the bottom of the welding base plate 2 and is located below the welding groove 21. The top of the fixed positioning seat 65 is symmetrically provided with two first positioning holes 653, which communicate with the welding groove 21. The two ends of the movable positioning seat 61 match the chain grooves 911 of the chain link 91. The two ends of the movable positioning seat 61 are used to insert into the chain grooves 911 of the chain link 91. The two ends of the movable positioning seat 61 are symmetrically provided with two second positioning holes 612. The center of the bottom of the movable positioning seat 61 is provided with a third positioning pin. Positioning hole 611; connecting pin 62 is movably inserted into the second positioning hole 612 and the upper chain hole 912 of the chain link 91, so that the chain link 91 is connected to both ends of the movable positioning seat 61, which facilitates the insertion of the chain link 91 and the removal of the finished product; connecting positioning seat 64 is fixed on the top of the welding base plate 2 and is located between two adjacent welding grooves 21. The top of the connecting positioning seat 64 is provided with a positioning slot 641, and the movable positioning seat 61 is movably inserted into the positioning slot 641; positioning pin 66 is fixed at the bottom of the positioning slot 641 and is movably inserted into the third positioning hole 611. The positioning pin 66 and the positioning slot 641 cooperate to realize the positioning of the movable fixed seat.

[0035] The positioning device 6 facilitates the insertion and positioning of the chain link 91. The symmetrical arrangement of the structure allows one positioning device 6 to position two chain links 91, improving the efficiency of welding preparation, and making full use of the clamping device 3, reducing the number of clamping cylinders 32, and improving the utilization rate of the clamping device 3.

[0036] To facilitate the installation and removal of the movable positioning seat 61, a handle 63 is installed on the top of the movable positioning assembly.

[0037] To prevent the connecting pin 62 from falling off and to facilitate positioning, a limiting ring is provided at one end of the connecting pin 62. The limiting ring abuts against one end of the chain link 91 to prevent the connecting pin 62 from moving axially.

[0038] To facilitate the machining of the first positioning hole 653, the fixed positioning seat 65 includes a first positioning seat 651 and a first positioning plate 652. Two first positioning holes 653 are symmetrically provided on one side of the first positioning seat 651. The first positioning plate 652 is fixed to the side of the first positioning seat 651 by screws to achieve side closure of the two first positioning holes 653.

[0039] The clamping device 3 includes a clamping cylinder 32, a clamping rod 31, and clamping blocks. The clamping cylinder 32 is fixed to the bottom of the welding base plate 2. The piston rod of the clamping cylinder 32 passes through the welding base plate 2 and is connected to the clamping rod 31. The clamping rod 31 is located at the top of the welding base plate 2 and above the scraper 92. The clamping blocks are symmetrically fixed at both ends of the clamping rod 31. The clamping blocks are also arranged opposite to the scraper 92 to press the scraper 92 against the welding base plate 2.

[0040] During operation, the positioner 1 rotates the welding base plate 2 to a horizontal position with the top of the welding base plate 2 facing upwards. The piston rod of the clamping cylinder 32 is extended. The operator first inserts both ends of the movable positioning seat 61 into the chain groove 911 of the chain link 91, and then inserts the connecting pin 62 into the upper chain hole 912 of the chain link 91 and the second positioning hole 612 of the movable positioning seat 61. The two chain links 91 are lifted by the handle 63, and then the chain links 91 are inserted into the first positioning hole 653 of the fixed positioning seat 65 through the welding groove 21. The movable positioning seat 61 is first inserted into the positioning slot 641, and then the third positioning hole 611 is inserted into the positioning pin 66 until the movable positioning seat 61 reaches the bottom of the positioning slot 641, and the two chain links 91 are positioned. Next, the scraper 92 is placed on the welding base plate 2, with one side of the scraper 92 abutting against the positioning pin 4 and the end of the scraper 92 abutting against the side of the chain link 91. Then, the clamping cylinder 32 is activated, and the piston rod of the clamping cylinder 32 retracts. The clamping rod 31 presses the scraper 92 onto the welding base plate 2 through the clamping block, thus fixing the scraper 92. During welding, the welding gun is driven by a robotic arm or welding is performed manually. After the scrapers 92 on the top of the welding base plate 2 are all welded to the chain link 91, the positioner 1 rotates the welding base plate 2 180° so that the bottom of the welding base plate 2 faces upward. The other side of the scraper 92 is then welded through the welding groove 21, thereby achieving the welding of the two welding bevels at the end of the scraper 92.

[0041] Positioner 1 can be set to an angle as needed. Positioner 1 is an existing mature product.
