Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding device for processing reducer gears. Background Art

[0002] The gear of the reducer is one of the mechanical elements that plays a role in reducing speed in the reducer. The gear reducer that realizes transmission, speed regulation and torque amplification through the meshing of gears uses various levels of gear transmission to achieve the purpose of speed reduction. For example, a small gear drives a large gear to achieve a certain deceleration effect. If a multi-level structure is adopted, the speed can be greatly reduced. At the same time, the reducer will have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. The gear of the reducer is usually composed of gears, shafts, housings, bearings, etc. Among them, gears are the main components of the reducer gears. According to the meshing mode, gears can be divided into internal meshing gears and external meshing gears; according to the material, they can be divided into steel gears, cast iron gears, copper gears, etc. The reducer gears are the key components of the reducer. Their performance and quality directly affect the overall performance and service life of the reducer. Therefore, the processing technology of the reducer gears is particularly important.

[0034] It should be noted that the specific installation method of the control component 5 and the robot welding arm 6 in the present invention, the circuit connection method and the control method are all conventional designs, which are conventional design means of designers. The control component 5 is composed of components such as a control center, a display, a receiver and a processor. In addition, the robot welding arm 6 is composed of a robot arm body, a welding system, a control system, a visual monitoring system and auxiliary devices, etc., which are used in conjunction with the control component 5 to realize automated and precise welding operations, and the welding process can be observed in real time through the control component 5.

[0035] First, the fixing mechanism 7 is moved forward by adjusting the workbench assembly 2, and then reducer gears of different types and sizes can be installed through the fixing mechanism 7. The workbench assembly 2 is adjusted again to restore the fixing mechanism 7 with the reducer gear installed to its initial position. Then, the robot welding arm 6 is controlled by operating the control component 5 to weld the reducer gear in the fixing mechanism 7. During the welding process, the strong light generated by the welding can be shielded by the cooperation of the shading plate 2 3 and the workbench assembly 2. At the same time, the welding condition of the reducer gear can be observed at all times through the display of the control component 5.

[0036] In order to achieve the purpose of cooperating with the fixing mechanism 7 to fix the reducer gear and shield the strong light generated by welding, Figure 3 - Figure 5 As shown, a mounting groove 25 is provided in the middle of the upper end of the table 21, a U-shaped frame 22 is fixedly connected to the rear side of the middle of the lower end of the table 21, a mounting groove 24 is provided on the right side of the front side of the upper end of the table 21, a sunshade 23 is slidably connected to the inner cavity of the mounting groove 24, a tooth plate 27 is fixedly connected to the lower end of the sunshade 23, a transmission component 28 is fixedly connected to the middle of the lower end of the table 21, a transmission component 26 is fixedly connected to the front side of the middle of the lower end of the table 21, and the transmission component 26 is located on the right side of the transmission component 28, the transmission component 26 is connected to the transmission component 28 through a belt, the lower side of the outer surface of the tooth plate 27 is meshed with the transmission component 26, the lower end of the U-shaped frame 22 is fixedly connected to the support leg 1 located on the rear side of the middle, and the lower end of the table 21 is fixedly connected to the other four support legs 1.

[0037] First of all, it should be noted that the transmission component 1 26 is composed of a toothed plate, a mounting seat, and a transmission wheel, and the transmission component 2 28 is composed of a mounting seat, a threaded rod, and a transmission wheel, and the transmission wheel in the transmission component 1 26 and the transmission wheel in the transmission component 2 28 are connected by a belt, and the gear in the transmission component 1 26 is meshed with the toothed plate 1 27;

[0038] First, the fixing mechanism 7 is installed through the installation groove 25 and the transmission component 28. In the initial state, the shading plate 23 is located on the left side of the inner cavity of the installation groove 24. When the reducer gear needs to be installed through the fixing mechanism 7, the shading plate 23 is pushed to the right, so that the shading plate 23 drives the toothed plate 27 to slide to the right in the inner cavity of the installation groove 24. The toothed plate 27 slides to the right, driving the toothed disc in the transmission component 26 to rotate, and under the coordinated use of the belt, the transmission wheel in the transmission component 26 and the transmission wheel in the transmission component 28, the threaded rod in the transmission component 28 is driven to rotate, thereby driving the fixing mechanism 7 to move forward in the inner cavity of the installation groove 25. , then install the reducer gear into the fixing mechanism 7, then push the visor 1 23 to the left to restore it to its initial position, and then restore the fixing mechanism 7 with the reducer gear installed to its initial position, and finally control the robot welding arm 6 to weld the reducer gear in the fixing mechanism 7 by operating the control component 5, and block the strong light generated during the welding process through the cooperation of the visor 1 23 and the visor 2 3 to prevent damage to the eyes of the staff, and at the same time, the welding picture is displayed through the control component 5, which is convenient for the staff to observe the welding situation in real time, and finally achieves the purpose of cooperating with the fixing mechanism 7 to complete the fixation of the reducer gear and block the strong light generated by welding.

[0039] Embodiment 2, based on embodiment 1, completes the fixing of reducer gears of different types and sizes, such as Figure 6 and Figure 7 As shown, the fixing mechanism 7 includes a U-shaped frame 71, a sliding sleeve 79 is fixedly connected to the middle part of the lower end of the U-shaped frame 71, a left-right symmetrical roller plate 77 is provided at the lower end of the U-shaped frame 71, four supporting columns 73 are fixedly connected to the bottom wall of the inner cavity of the U-shaped frame 71, and the upper ends of the four supporting columns 73 are commonly fixedly connected to a clamping assembly 74, an electric telescopic rod 78 is fixedly connected to the middle part of the bottom wall of the inner cavity of the U-shaped frame 71, and the output end of the electric telescopic rod 78 is fixedly connected to the supporting assembly 72, a mounting plate 76 is fixedly connected to the right side of the front wall of the inner cavity of the U-shaped frame 71, and a driving component 75 is fixedly connected to the rear end of the mounting plate 76, the upper side of the driving component 75 is meshed with the front part of the upper side of the clamping assembly 74, the outer surface of the sliding sleeve 79 is slidably connected to the inner cavity of the mounting groove 25, the inner cavity of the sliding sleeve 79 is meshed with the outer surface of the transmission component 28, and the lower sides of the outer surfaces of the two roller plates 77 are commonly fitted with the middle part of the upper end of the table 21.

[0040] It should be noted that the specific installation method, circuit connection method and control method of the driving component 2 75 and the electric telescopic rod 78 in the present invention are all conventional designs, which are conventional design means of designers. The driving component 2 75 and the electric telescopic rod 78 are both controlled by the control component 5 and cooperate with each other to complete the welding work of the reducer gear. In addition, the driving component 2 75 is composed of a motor, a limiter, and a gear plate. The function of the limiter is to lock the motor when the motor is not rotating, so that it cannot rotate due to external force, thereby ultimately limiting the rotation of the clamping assembly 74.

[0041] First, when the threaded rod in the transmission component 28 rotates, the sliding sleeve 79 will slide forward in the inner cavity of the installation groove 25, while driving the U-shaped frame 271 to move together, and the two roller plates 77 will roll forward on the upper end of the table 21 to a suitable position, and then the driving component 275 will be controlled to rotate by the operation control component 5. The rotation of the driving component 275 can drive the clamping component 74 to fix the reducer gears of different models and sizes, and when the reducer gear is small and the clamping component 74 cannot be fixed, the electric telescopic rod 78 can also drive the support component 72 to move vertically upward and pass through the middle of the clamping component 74 to clamp and fix the smaller reducer gear. In addition, in some special cases, the clamping and fixing of the reducer gear can be completed by the clamping of the clamping component 74 and the support of the support component 72, so that the device has three clamping and fixing methods, which makes the device more applicable and ultimately achieves the purpose of fixing reducer gears of different types and sizes.

[0042] Further explanation, such as Figure 8 As shown, the clamping assembly 74 includes a mounting plate 741, and four sliding grooves 1 742 are provided in a circular array on the upper end of the mounting plate 741. Four mounting grooves 3 743 are provided in a circular array on the upper end of the mounting plate 741. The four sliding grooves 1 742 are staggered with the four mounting grooves 3 743. The inner cavities of the four mounting grooves 3 743 are all slidably connected with clamping blocks 746. The upper ends of the four clamping blocks 746 are fixedly connected with sliding columns 745 on the sides away from each other. The outer surfaces of the four sliding columns 745 and the inner cavities of the four sliding grooves 1 742 are jointly provided with a rotating group 744. The lower end of the mounting plate 741 is fixedly connected to the upper ends of the four support columns 73.

[0043] In detail, when the driving component 2 75 rotates, it will drive the rotating group 744 to rotate on the outer surface of the four sliding columns 745 and the inner cavity of the four sliding grooves 1 742, and with the cooperation of the four sliding columns 745, it will drive the four clamping blocks 746 to slide toward the center of the mounting plate 741 in the inner cavity of the four mounting grooves 3 743 respectively, and the four clamping blocks 746 sliding in opposite directions are used to clamp and fix the reducer gears of different types and sizes, and when the driving component 2 75 rotates in the opposite phase, the four clamping blocks 746 will release the clamping of the reducer gears.

[0044] Further explanation, such as Fig. 9 As shown, the rotating group 744 includes a rotating disk 7441, and four arc grooves 7443 are opened in a circular array at the upper end of the rotating disk 7441, and four sliders 2 7444 are fixedly connected to the circular array at the lower end of the rotating group 744, and an arc rack 7442 is fixedly connected to the right front side of the outer surface of the rotating group 744, and the inner cavities of the four arc grooves 7443 are respectively slidably connected to the outer surfaces of four sliding columns 745, and the outer surfaces of the four sliders 2 7444 are respectively slidably connected to the inner cavities of four sliding grooves 1 742.

[0045] In detail, when the driving component 2 75 rotates and with the cooperation of the arc-shaped rack 7442, the rotating disk 7441 will drive the four sliders 2 7444 to rotate in the inner cavities of the four sliding grooves 1 742 respectively, and the inner cavities of the four arc-shaped grooves 7443 will slide on the outer surfaces of the four sliding columns 745 respectively, and finally drive the four clamping blocks 746 to slide away from or towards each other at the same time.

[0046] In order to achieve the purpose of clamping and fixing the smaller reducer gears, such as Fig.10 As shown, the support assembly 72 includes a sleeve 721, and three mounting grooves 5 729 are provided in a circular array on the upper end of the sleeve 721. The inner cavities of the three mounting grooves 5 729 are all slidably connected with the sliding group 722, and the inner cavities of the three mounting grooves 5 729 are fixedly connected with the sliding block 1 728 on both side walls of the inner cavities away from each other. Three mounting grooves 4 724 are provided in a circular array on the bottom wall of the inner cavity of the sleeve 721. The inner cavities of the three mounting grooves 4 724 are all rotatably connected with the rotating gear columns 723. The outer surfaces of the three rotating gear columns 723 are meshingly connected with the ring gear 726. The outer surface of the ring gear 726 is rotatably connected to the inner cavity of the sleeve 721. A driving component 1 727 is fixedly connected to the front middle part of the bottom wall of the inner cavity of the sleeve 721. The output end of the driving component 1 727 is connected to the rotating component 725 through belt winding, and the outer surface of the rotating component 725 is meshingly connected with the ring gear 726.

[0047] It should be noted that the specific installation method of the driving component 727, the connection method of the circuit and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the driving component 727 is controlled by the control component 5. In addition, the driving component 727 is composed of a motor and a transmission wheel group, and the rotating component 725 is composed of a gear plate and a transmission wheel. The transmission wheel in the rotating component 725 is connected to the transmission wheel in the driving component 727 through a belt, and the rotating component 725 is rotatably connected to the front side of the inner cavity of the sleeve 721.

[0048] First, the electric telescopic rod 78 drives the sleeve disc 721 to move vertically upward and pass through the inner cavities of the mounting disc 741 and the rotating disc 7441 to a suitable position, and then the driving component 1 727 is controlled and used in conjunction with the belt to make the rotating component 725 rotate in the inner cavity of the sleeve disc 721, and the rotation of the rotating component 725 drives the gear ring 726 to rotate in the inner cavity of the sleeve disc 721, and then the rotation of the gear ring 726 further drives the three rotating gear columns 723 to rotate together in the inner cavities of the mounting groove 4 724, thereby making the three sliding groups 722 slide towards each other or away from each other in the inner cavities of the three mounting grooves 5 729 at the same time, and each of the inner cavities of the mounting groove 5 729 is fixedly installed with a slider 1 728 on both sides of the inner wall, which is used to limit The sliding range of the sliding group 722 prevents the sliding group 722 from escaping from the inner cavity of the mounting groove five 729. Through the mutual sliding of the three sliding groups 722, the arc surfaces of the three sliding groups 722 that are close to each other are clamped to the smaller reduction gear, or the inner cavity of the smaller reduction gear is supported by the vertical arc surfaces of the three sliding groups 722, and the lower end of the smaller reduction gear is supported by the horizontal upper ends of the three sliding groups 722, thereby finally completing the purpose of clamping and fixing the smaller reduction gear. In addition, under special circumstances, when it is necessary to cooperate with the clamping assembly 74 to clamp and fix the reduction gear, the bottom of the reduction gear is supported by the vertical or horizontal upper ends of the three sliding groups 722, thereby completing the purpose of clamping and fixing the reduction gear under special circumstances.

[0049] Further explanation, such as Fig.11 As shown, the three sliding groups 722 all include an L-shaped support block 7221, and the side ends of the three L-shaped support blocks 7221 that are close to each other are each provided with a slide groove 7222, and the lower ends of the three L-shaped support blocks 7221 are each provided with a groove 7223, and the side walls of the inner cavities of the three grooves 7223 are fixedly connected with a tooth plate 2 7224, and the lower side of the outer surface of the L-shaped support block 7221 on the same side is slidably connected to the inner cavity of the mounting groove 5 729, and the inner cavities of the two slide grooves 7222 on the same side are respectively slidably connected to the outer surfaces of the two sliding blocks 1 728, and the outer surfaces of the three tooth plates 2 7224 are respectively meshed with the outer surfaces of the three rotating gear columns 723.

[0050] In detail, when the three rotating gear columns 723 rotate at the same time, the tooth plate 2 7224 on the same side will be driven to move, and with the cooperation of the slider 1 728 and the slide groove 7222, the three L-shaped support blocks 7221 will move away from or towards each other in the inner cavities of the three mounting grooves 5 729 respectively, and the smaller reducer gear can be clamped and fixed by the sides of the three L-shaped support blocks 7221 that are close to each other in the vertical direction, or the inner diameter of the smaller reducer gear can be supported by the sides of the three L-shaped support blocks 7221 that are away from each other in the vertical direction, so as to achieve the purpose of fixing the smaller reducer gear and facilitating welding.
