Detailed implementation manners

[0029] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0030] Example 1, referring to Figure 1 - Figure 4 , which is the first embodiment of the present invention, provides a multi-station automatic welding robot for the housing of a generator set. This device includes: an operating table unit 100, a fixing unit 200, and a welding unit 300.

[0031] Among them, the operation table unit 100 includes an operation table 101; The fixing unit 200 includes a fixing component 201 arranged on the top of the operation table 101; The welding unit 300 includes an automatic robotic arm component 301 arranged at the bottom of the operation table 101, a connecting component 302 arranged at the output end of the automatic robotic arm component 301, a welding component 303 rotatably arranged at the bottom of the connecting component 302, a supporting component 304 arranged on the outer diameter of the welding component 303, and a working position switching component 305 arranged on the supporting component 304. The working position switching component 305 cooperates with the fixing component 201. When welding the generator housing, the operator places the housings to be welded at both ends inside the fixing component 201 on the top of the operation table 101. With the drive of the fixing component 201, the housings to be welded are clamped and fixed. After the fixing is completed, the automatic robotic arm component 301 starts to work and adjusts its position, so that the connecting component 302 extends, and the connecting component 302 rotates to adjust the angle, enabling the welding component 303 to extend into the generator housing to be welded. After the welding component 303 extends into the generator housing, the welding component 303 drives the supporting component 304 to move, causing the supporting component 304 to expand in all directions, so that the supporting component 304 is supported and fixed inside the generator housing. After the supporting component 304 is supported and fixed, the working position switching component 305 cooperates with the welding component 303 to start adjusting the welding position and welding angle. After the position and angle adjustment are completed, the working position switching component 305 disengages from the connection with the welding component 303, and the welding component 303 starts to drive to perform multi-angle welding inside the generator housing.

[0032] During use, when welding the generator housing, the operator places the housings to be welded at both ends inside the fixing component 201 on the top of the operating table 101. Driven by the fixing component 201, the housings to be welded are clamped and fixed. After the fixing is completed, the automated robotic arm component 301 starts to work and adjusts its position, so that the connecting component 302 extends, and the connecting component 302 rotates to adjust the angle, enabling the welding component 303 to extend into the generator housing to be welded. After the welding component 303 extends into the generator housing, the welding component 303 drives the support component 304 to move, causing the support component 304 to expand in all directions, so that the support component 304 is supported and fixed inside the generator housing. After the support component 304 is supported and fixed, the station switching component 305 cooperates with the welding component 303 to start adjusting the welding position and welding angle. After the position and angle adjustment are completed, the station switching component 305 disengages from the connection of the welding component 303, and the welding component 303 starts to drive to perform multi-angle welding inside the generator housing, solving the problems in the traditional welding method, such as time-consuming and laborious welding due to narrow space and harsh environment, difficulty in achieving circular welding, and inability to adjust the welding direction and angle, improving the welding quality and efficiency, reducing the labor cost, enhancing the production efficiency, and avoiding the situation where the welding operation space is narrow, the environment is harsh, it is difficult to achieve circular welds and the direction and angle cannot be adjusted, which affects the quality and efficiency.

[0033] Embodiment 2, referring to Figure 1 - Figure 8 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the fixing component 201 includes a driving member 2011 arranged on the top of the operating table 101, a moving member 2012 movably arranged inside the driving member 2011, a fixing clamp ring 2013 arranged on the moving member 2012, and a friction pad 2014 arranged on the inner wall of the fixing clamp ring 2013. Compared with Embodiment 1, further, the automated robotic arm assembly 301 includes a connecting rod 3011 disposed at the bottom of the operating table 101, a first fixing block 3012 disposed at one end of the connecting rod 3011, a base 3013 disposed on top of the first fixing block 3012, a driving part 3014 disposed on top of the base 3013, a first linkage rod 3015 disposed on the driving part 3014, and a connecting shaft 3016 disposed at the other end of the first linkage rod 3015. The connecting assembly 302 includes an adjusting shaft 3021 rotatably disposed at the bottom of the connecting shaft 3016, a rotating member 3022 rotatably disposed on the adjusting shaft 3021, a first connecting plate 3023 disposed at one end of the rotating member 3022, a support rod 3024 disposed at the other end of the first connecting plate 3023, and a second connecting plate 3025 disposed at the other end of the support rod 3024. The second connecting plate 3025 penetrates and is rotatably connected to the welding assembly 303. When internally welding the generator housing, the generator housings to be welded on both sides are respectively placed inside the fixing rings 2013 on both sides. Then, the driving member 2011 is driven to make the moving member 2012 drive the fixing rings 2013 to move and start clamping and fixing the generator housings inside the fixing rings 2013. At the same time, the friction pads 2014 inside the fixing rings 2013 can increase the fixing friction force on the generator housings. And after the fixing rings 2013 complete the fixing of the generator housings, the driving part 3014 on top of the first fixing block 3012 and the base 3013 is driven to make the first linkage rod 3015 start to move and adjust its position, so that the connecting assembly 302 and the welding assembly 303 extend into the generator housing to be welded, preparing for the subsequent welding of the generator and ensuring the subsequent welding process.

[0034] During use, when internally welding the generator housing, the generator housings to be welded on both sides are respectively placed inside the fixing rings 2013 on both sides. Then, the driving member 2011 is driven to make the moving member 2012 drive the fixing rings 2013 to move and start clamping and fixing the generator housings inside the fixing rings 2013. At the same time, the friction pads 2014 inside the fixing rings 2013 can increase the fixing friction force on the generator housings. And after the fixing rings 2013 complete the fixing of the generator housings, the driving part 3014 on top of the first fixing block 3012 and the base 3013 is driven to make the first linkage rod 3015 start to move and adjust its position, so that the connecting assembly 302 and the welding assembly 303 extend into the generator housing to be welded, preparing for the subsequent welding of the generator and ensuring the subsequent welding process, improving the welding quality and efficiency, reducing the labor cost, enhancing the production efficiency, and avoiding the problems of narrow welding operation space, harsh environment, difficulty in achieving circumferential welds and non-adjustable direction angles, which affect the quality and efficiency and increase the labor cost.

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 3, reference Figure 1 - Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a welding assembly 303 includes a motor 3031 arranged on a connecting plate 3023, a transmission rod 3032 arranged at the output end of the motor 3031, a rotating part 3036 arranged at the other end of the transmission rod 3032, a rotating rod 3037 rotatably arranged inside the rotating part 3036, a bevel gear 3038 arranged on the outer diameter of the rotating rod 3037, and a movable welding head 3039 arranged at the other end of the bevel gear 3038, a thread groove 3033 is arranged on the outer diameter of the transmission rod 3032, an annular groove 3034 is arranged at one end of the thread groove 3033, and the annular groove 3034 is also arranged on the outer diameter of the transmission rod 3032, an arc guide block 3035 is arranged inside the annular groove 3034, and the arc guide block 3035 cooperates with the support assembly 304, after the position adjustment of the automated robotic arm assembly 301 is completed, the adjustment shaft 303 is adjusted. After 021 and rotating member 3022 extend into the generator housing, the motor 3031 on the connecting plate 1 3023 and the connecting plate 2 3025 drives the transmission rod 3032 to rotate. While the transmission rod 3032 rotates, the fixed block 2 3042 inside the moving ring 3041 on the outer diameter of the transmission rod 3032 begins to move with the rotation of the thread groove 3033. At the same time, during the movement of the moving ring 3041, the rotating shaft 3043 and the linkage rod 2 3044 begin to rotate and adjust their positions, so that the rotating push rod 3045 begins to expand outward along the inside of the fixed disk 3046, so that the rotating push rod 3045 can be expanded to support and fix inside the generator housing, and when the rotating push rod 3045 is completely expanded, the fixed block 2 3042 inside the moving ring 3041 slides from the inside of the thread groove 3033 into the inside of the annular groove 3034 to ensure preparation for subsequent rotation welding.

[0037] Compared with Embodiment 2, further, the support component 304 includes a moving ring 3041 slidably disposed on the outer diameter of the transmission rod 3032, a linkage rod two 3044 rotatably disposed inside the moving ring 3041, and a rotating push rod 3045 rotatably disposed at the other end of the linkage rod two 3044. A fixed block two 3042 is disposed inside the moving ring 3041, and the fixed block two 3042 is slidably connected to the thread groove 3033. One end of the connecting plate two 3025 is provided with a fixed disk 3046, and the fixed disk 3046 is slidably connected to the rotating push rod 3045. The station switching component 305 includes an electric push rod 3051 disposed inside the connecting plate two 3025, a moving clamping plate 3052 disposed at the output end of the electric push rod 3051, and a bevel gear two 3053 disposed on the moving clamping plate 3052, and the bevel gear two 3053 is slidably connected to the rotating portion 3036. After the rotating push rod 3045 completes the support and fixation, the electric push rod 3051 on the connecting plate two 3025 starts to drive the moving clamping plate 3052 and the bevel gear two 3053 to move along the outer diameter of the rotating portion 3036, so that the bevel gear two 3053 can be in contact connection with the bevel gear one 3038. Then, the motor 3031 drives the transmission rod 3032 to drive the rotating portion 3036 to rotate. During the rotation of the rotating portion 3036, the bevel gear one 3038 on the rotating rod 3037 meshes with the bevel gear two 3053, so that the bevel gear one 3038 drives the rotating rod 3037 and the moving welding head 3039 to rotate to start adjusting the welding position and welding angle. After the adjustment is completed, the electric push rod 3051 drives the bevel gear two 3053 to disengage from the bevel gear one 3038, so that the bevel gear one 3038 and the moving welding head 3039 complete the position adjustment and start rotating welding inside the generator housing under the drive of the motor 3031. After the welding is completed, the motor 3031 rotates in the reverse direction, so that the fixed block two 3042 inside the annular groove 3034 is reversely extruded and guided by the arc-shaped guide block 3035, so that the fixed block two 3042 returns from the inside of the annular groove 3034 to the inside of the thread groove 3033 again and moves along the transmission rod 3032, so that the rotating push rod 3045 retracts again, so as to release the fixation inside the generator housing, and thus can move out from the inside of the welded generator housing, so that the welding is completed.

[0038] During use, after the position adjustment of the automated robotic arm assembly 301 is completed, the adjustment shaft 3021 and the rotating member 3022 are extended into the interior of the generator housing, and the motor 3031 on the connecting plate 1 3023 and the connecting plate 2 3025 drives the transmission rod 3032 to rotate. While the transmission rod 3032 rotates, the fixed block 2 3042 inside the moving ring 3041 on the outer diameter of the transmission rod 3032 begins to move with the rotation of the thread groove 3033. At the same time, during the movement of the moving ring 3041, the rotating shaft 3043 and the linkage rod 2 3044 begin to rotate and adjust the position, so that the rotating push rod 3045 begins to expand outward along the inside of the fixed disk 3046, so that the rotating push rod 3045 can be expanded to support and fix inside the generator housing, and when the rotating push rod 3045 is completely expanded, the fixed block 2 3042 inside the moving ring 3041 slides from the inside of the thread groove 3033 into the inside of the annular groove 3034 to ensure preparation for subsequent rotation welding.

[0039] After the rotating push rod 3045 completes the support and fixation, the electric push rod 3051 on the connecting plate 2 3025 starts to drive the moving card plate 3052 and the bevel gear 2 3053 to move along the outer diameter of the rotating part 3036, so that the bevel gear 2 3053 can be in contact with the bevel gear 1 3038, and then the motor 3031 drives the transmission rod 3032 to rotate with the rotating part 3036. During the rotation of the rotating part 3036, the bevel gear 1 3038 on the rotating rod 3037 is meshed with the bevel gear 2 3053, so that the bevel gear 1 3038 rotates with the rotating rod 3037 and the moving welding head 3039 to start adjusting the welding position and welding angle, so that the bevel gear 1 3038 can be adjusted by 360 degrees in a multi-station rotation along the bevel gear 2 3053, so that the welding head 3039 can be rotated. 039 completes the multi-angle welding work, and after the adjustment is completed, the electric push rod 3051 drives the bevel gear 2 3053 to disengage from the bevel gear 1 3038, so that the bevel gear 1 3038 and the mobile welding head 3039 complete the position adjustment, and start the rotation welding inside the generator housing under the drive of the motor 3031. After the welding is completed, the motor 3031 rotates in the opposite direction, so that the fixed block 2 3042 inside the annular groove 3034 is reversely extruded and guided by the arc-shaped guide block 3035, so that the fixed block 2 3042 returns from the inside of the annular groove 3034 to the inside of the threaded groove 3033, and moves along the transmission rod 3032, so that the rotating push rod 3045 retracts again, so that the fixation on the inside of the generator housing is released, so that it can be moved out from the inside of the generator housing after welding, so that the welding is completed.
