Description

[0002] The background technology of large-scale chain welding equipment can be traced back to the limitations of manual or semi-automatic welding methods in traditional chain manufacturing processes. Early chain production mainly relied on arc welding or resistance welding technology. Although these methods can meet general strength requirements, they will lead to problems such as difficult production operations and low production efficiency when welding large-diameter chains.

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example 1: like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 9As shown, a welding device for processing ring chains includes a workbench 10, and a flash welder 22 is provided on the upper end surface of the workbench 10. The flash welder 22 is an ordinary flash welding device, which is a prior art and can perform high-strength and rapid welding of ring chains. The welding base of the flash welder 22 is provided with an arc groove for supporting the chain links of the ring chain. The sliding welding end of the flash welder 22 is also provided with an arc groove plate. When welding each chain link, a downward pressure and fixed clamping of the chain link will be formed.

[0021] The two sides of the flash welding machine 22 are slidably provided with a sliding frame 11, and one end face of each sliding frame 11 is provided with a square hole 12, and a turntable 13 is rotatably provided inside each square hole 12, and one end face of each turntable 13 is provided with a cross through hole 15. Since the two ends of the chain will be stretched during welding, it is convenient to weld the chain. At this time, every two adjacent chain links will present a horizontal state and a vertical state. The shape of the cross through hole 15 is convenient for the horizontal passage of multiple chain links. A sliding clamp 16 is slidably provided inside the four long grooves of each cross through hole 15, and a clamping roller 17 is rotatably provided inside each sliding clamp 16. The outer circumference of each clamping roller 17 is provided with an annular arc groove that can better fit the outer circumference of the chain link. Second slide grooves 44 are provided on both sides of the sliding clamp 16 inside the cross through hole 15, and a second slider 45 is slidably provided inside each second slide groove 44. Each second slider 45 is The first spring 18 is arranged between the two guide rails 16 and the cross hole 15 so that the chain links 16 can slide freely in the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15. When the chain links 16 are welded, the first spring 18 is arranged between the two guide rails 16 and the cross hole 15

[0022] Further, such as Figure 1 、 Figure 7 and Figure 8As shown, the outer circumference of each turntable 13 is provided with a gear ring 14, and a transmission gear 19 is rotatably provided on one side of each gear ring 14 inside the sliding frame 11. Each transmission gear 19 is meshed with its adjacent gear ring 14, and a telescopic transmission rod 20 is connected between the two transmission gears 19. The telescopic transmission rod 20 is a prior art, and its length can be adjusted according to the distance between the two sliding frames 11, so that the two turntables 13 rotate synchronously, ensuring that the welding part of each chain entering the flash welder 22 can remain in a vertical state, thereby improving the accuracy and efficiency of welding. A motor 21 is provided on the side wall of the sliding frame 11 on one side of the transmission gear 19. The motor 21 provides driving force for the rotation of the transmission gear 19. A plurality of support rollers 43 are provided in a ring shape on both sides of each gear ring 14 on the outside of the turntable 13. A support frame is provided on the outside of each support roller 43. Each support frame is fixedly connected to the inner side wall of its adjacent square hole 12. The plurality of support rollers 43 are rotatably abutted against the outer cylindrical surface of the adjacent turntable 13 to ensure stable rotation of the turntable 13. At the same time, the plurality of support rollers 43 can also form a center positioning for the turntable 13 when it rotates inside the square hole 12.

[0023] Further, such as Figure 3As shown, one side of each sliding frame 11 is provided with a chain winding assembly on the lower end surface of the workbench 10, and each chain winding assembly includes a winding roller 27 rotatably arranged on the lower end surface of the workbench 10, and a connecting rope 28 is wound and connected inside each winding roller 27, and a hook 29 is provided at the end of each connecting rope 28, and each hook 29 is mutually engaged with the end link of the chain. A rebound reel 46 is provided on one side of the winding roller 27 at one end of the chain welding tail, and the elastic winding end of the rebound reel 46 is fixedly connected to one side of the winding roller 27, and a driving motor is provided on one side of the winding roller 27 at one end of the chain welding head to drive the winding roller 27 to rotate. The interior of the rebound reel 46 includes components such as a coil spring shaft, and the shaft is fixedly connected to the side wall of the adjacent winding roller 27. When the chain welding is performed, the coil spring inside the rebound reel 46 will form an elastic tension on the winding roller 27 adjacent to it through its own elastic tension. The winding and rotation of the wound connecting rope 28 causes the connecting rope 28 to pull the tail of the chain to be welded through the hook 29, while the other end of the chain is pulled and fixed by a combination of another winding roller 27, the connecting rope 28 and the hook 29, thereby forming a tension on the entire chain, ensuring the stability of the chain link during welding, and when the chain link is continuously welded, the driving motor will drive the winding roller 27 connected to it to rotate, thereby winding the connecting rope 28 and driving one end of the chain to move horizontally. The driving motor has the characteristics of precise rotation and self-locking. Under the control of the intelligent controller of the equipment, the winding length of each time can be controlled according to the length of each link, thereby realizing continuous welding of the chain, and when welding a longer chain, the initial chain can also be wound on the winding roller 27 on one side of the rebound winder 46, and the chain after welding can be wound on the winding roller 27 on the other side, forming automatic welding of the chain.

[0024] Further, such as Figure 1 and Figure 3As shown, a first supporting roller 42 is provided on the side wall of the workbench 10 on one side of each winding roller 27, and each first supporting roller 42 is rotatably abutted with its adjacent connecting rope 28. The setting of the first supporting roller 42 plays a guiding and transmission role for the connecting rope 28 and the chain link during the chain welding process, preventing friction between the chain or the connecting rope 28 and the workbench 10, and a rotating rod 30 is rotatably provided on the side wall of the sliding frame 11 on one side of each first supporting roller 42, and a first supporting roller 31 is rotatably provided inside each rotating rod 30, and the outside of each rotating rod 30 is rotatably provided on the sliding frame 11. A rotating seat is fixedly provided on the side walls, and each rotating seat is fixed to the rotating rod 30 by bolts. The rotating rod 30 and the first supporting roller 31 play a supporting and guiding role in the process of welding the ring chain, forming a leveling effect for the horizontal movement of the ring chain between the two first supporting rollers 31, so that when the ring chain enters between the multiple sliding clamps 16 after passing through the support and guidance of the rotating rod 30 and the first supporting roller 31, it can ensure that the multiple chain links are always in the center of the cross through hole 15, ensuring that each subsequent chain link can maintain a horizontal state when entering the flash welder 22 for welding, thereby improving the accuracy of the ring chain welding.

[0025] Further, such as Figure 3 and Figure 5 As shown, a pressure sensor 23 is provided inside each first spring 18 on the inner bottom surface of the cross through hole 15, and a second spring 24 is provided between the pressure sensing end of each pressure sensor 23 and the sliding clamp 16. The pressure sensor 23 is a common pressure sensor. During the chain welding process, when the chain link moves to the welding position in the flash welder 22, a downward pressure structure will be formed inside the flash welder 22 to press down on the chain link. Due to the elastic stretching effect of the chain winding assembly on the two ends of the chain, the flash welder 22 will press down on the chain link. The pressure will drive the chains on both sides of the flash welder 22 to form a downward tilt stretching of the clamping chain between each two opposing clamping rollers 17, thereby causing the chains to squeeze the clamping roller 17 located below, causing the clamping roller 17 to drive the sliding clamping member 16 to move slightly vertically downward. The downward movement of the sliding clamping member 16 will squeeze the second spring 24. The compression of the second spring 24 will squeeze the output end of the pressure sensor 23. On the contrary, the clamping roller 17 located above will move vertically downward under the elastic action of the first spring 18. At this time, the clamping roller 17 drives the sliding clamping member 16 to move downward, so that the second spring 24 connected to the sliding clamping member 16 is subjected to the pressure of the sliding clamping member 16, thereby reducing the pressure on the output end of the pressure sensor 23 on the side of the second spring 24, thereby reducing the pressure on the output end of the pressure sensor 23 on the side of the second spring 24, thereby knowing whether the chain link has completed effective limit fixation inside the flash welder 22 through the pressure change on the two relative pressure sensors 23. When welding is completed, the flash welder 22 will release the downward pressure on the chain link, and the elastic pressure on the two relative pressure sensors 23 and the adjacent second spring 24 will change in the opposite direction, thereby knowing that the welding of the single chain link is completed, and the winding roller 27 is driven by the motor on one side of the winding roller 27 to rotate to form a horizontal movement of the endless chain, which is convenient for welding the next chain link. A plurality of first slide grooves 37 are provided below each sliding frame 11 on the upper end surface of the workbench 10, and a first slider 39 is slidably provided inside each first slide groove 37. Each first slider 39 is fixedly connected to the lower end surface of its adjacent sliding frame 11. A screw 38 is rotatably provided inside one of the first slide grooves 37, and each screw 38 is threadedly connected to its adjacent first slider 39. Guide rods 40 are provided inside the remaining first slide grooves 37, and each guide rod 40 is slidably connected to its adjacent first slider 39. A driving motor for driving the screw 38 to rotate is provided on one side of each screw 38. The screw 38 is driven to rotate by the driving motor, and the rotation of the screw 38 drives the sliding frame 11 to move horizontally on the upper end surface of the workbench 10.

[0026] It should be noted that the distance between the two sliding frames 11 needs to be adaptively adjusted according to the length of a single chain when the chain is welded. Figure 3 As shown in the figure, when the chain inside the flash welder 22 is welded, the single chain link inside each turntable 13 should be clamped up and down by the two clamping rollers 17 in the vertical direction, so as to ensure that when the flash welder 22 presses down on the welding chain, the chain clamped by the two clamping rollers 17 can press down the clamping rollers 17 in contact with it, thereby completing the welding state of the chain being fixed.

[0027] Further, such as Figure 7As shown, an arc-shaped fixing plate 25 is provided on the side wall of the turntable 13 between every two adjacent sliding clamps 16, and a high-definition camera 26 is provided on the inner arc surface of each arc-shaped fixing plate 25. Multiple high-definition cameras 26 form a 360-degree monitoring of the elastic telescopic rod of the ring chain, and the welding gap of the ring chain is determined by the built-in data analysis system of the equipment, so as to mark the gap position of the ring chain entering the inner part of the turntable 13. When each ring chain moves to the welding position of the flash welder 22, the welding port of the ring chain is marked. At the beginning of welding, each welding position of the ring chain passing through multiple high-definition cameras 26 will be marked. After the welding of each ring chain is completed, the next ring chain will move to the inside of the flash welder 22, and the electric Machine 21, so that the output end of the motor 21 drives the transmission gear 19 to rotate, and the transmission gear 19 drives the turntable 13 to rotate by engaging with the gear ring 14. Under the connecting action of the telescopic transmission rod 20 on the two transmission gears 19, the two transmission gears 19 rotate synchronously, thereby driving the two turntables 13 to rotate synchronously, so that the ring chain entering the flash welder 22 is rotated and adjusted until the ring chain is in a vertical state and the welding port is at the top. It should be noted here that the motor 21 is an existing motor with high output power, so as to ensure the starting pressure. The motor 21 drives the transmission gear 19 and the turntable 13 to rotate, and each rotation angle is a multiple of 90 degrees, so as to ensure the vertical state of the single ring chain inside the flash welder 22.

[0028] Further, such as Figure 1 As shown, a protective cover 41 is rotatably provided on the outside of the two sliding frames 11 on the upper end surface of the workbench 10. The rotating setting of the protective cover 41 can shield and protect the high-temperature debris splashed by the welding when the chain is welded, and the rotation of the protective cover 41 facilitates the maintenance of the equipment and the observation of the working progress of the chain inside the equipment. A plurality of support rods 47 are provided on one side of the protective cover 41 on the upper end surface of the workbench 10. The setting of the plurality of support rods 47 forms a support and fixation for one end of the protective cover 41.

[0029] Example 2: On the basis of the first embodiment, a further embodiment is made, such as Figure 1 and Figure 6As shown, a rotating plate 32 is rotatably provided on one side wall of each sliding clamping member 16 inside the turntable 13 near the rebound reel 46 side, and a rust removing wheel 33 is rotatably provided on the lower end surface of each rotating plate 32, and a driving motor is fixedly provided above each rust removing wheel 33 on the upper end surface of the rotating plate 32. A pulley is provided on the output end of the driving motor and on the side wall of the rust removing wheel 33. The driving motor and its adjacent rust removing wheel 33 are driven by a belt. A water-absorbing sponge 34 is provided on one side of each rust removing wheel 33 on the lower end surface of the rotating plate 32, and a liquid storage tank 35 is provided above each water-absorbing sponge 34 on the upper end surface of the rotating plate 32. Rust remover is provided inside the liquid storage tank 35, and each liquid storage tank 35 transports rust remover to the adjacent water-absorbing sponge 34 through a hose. When the chain passes through the first turntable 13, the upper and lower end surfaces of the chain links first contact the water-absorbing sponge 34, and then frictionally contact the rust removing wheel 33. The rust removing wheel 33 and the water-absorbing sponge 34 are used to polish the rust removing agent on the outer surface of each chain.

[0030] Finally, it should be noted that the welding equipment for chain processing of the present invention has common mechanical installation and connection methods or related positions of various structures, and the control systems for the movement of various internal structures also adopt conventional electrical control systems. As long as they can achieve their beneficial effects, they can be implemented; the motor 21, pressure sensor 23, rebound winder 46, high-definition camera 26 and related motors and controllers in the welding equipment for chain processing of the present invention are all purchased on the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, and there is no need for technical personnel in this field to pay creative labor.
