Description

Technical Field

[0001] This invention relates to the field of welding robot technology, and in particular to an automatic electrode shell assembly welding robot. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). To adapt to different applications, the mechanical interface of the robot's last axis is usually a connecting flange, which can be used to attach different tools or end effectors. Welding robots are industrial robots with welding clamps or welding (cutting) guns attached to the flange of the last axis, enabling them to perform welding, cutting, or thermal spraying. Electrode shells need to be welded and installed by welding robots during the production process. The electrode shell is composed of ribs and arc plates. When welding the motor shell, the user needs to manually load the electrode shell. The user fixes it using a fixing device carried on the upper part of the welding robot. However, the fixing device squeezes the two ends of the electrode shell during fixing, which can easily cause damage to the two ends of the electrode shell due to excessive tightening. At the same time, looseness when the user fixes the electrode shell with the fixing device can easily cause the electrode shell to shift in position during welding, reducing the practicality of the electrode shell installation and affecting the working efficiency of the welding robot. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, an automatic electrode shell assembly welding robot is provided.

[0004] The specific technical solution is as follows:

[0005] Design an automated electrode shell assembly welding robot, including a lower base welding slide, a mounting base, and a fixing device. The robot body is mounted on one side of the lower base welding slide. A welding carriage is movably connected to the side of the lower base welding slide away from the robot body. A drive motor is fixedly connected to the upper end of the welding carriage, and a welding turntable is movably connected to one end of the drive motor. The mounting base is fixedly connected to the upper end of the lower base welding slide. A right stiffener auxiliary mounting platform is provided on the upper end of the mounting base, and the right stiffener auxiliary mounting platform is close to the welding turntable. A clamp is fitted to one side of the lower base welding slide, and a left stiffening plate auxiliary installation platform is fixedly connected to the side of the lower base welding slide that is away from the mounting base. A movable welding clamp is provided on the side of the left stiffening plate auxiliary installation platform that corresponds to the welding turntable. The fixing device includes a connecting column, which is welded to the side of the welding cart that is close to the welding turntable. Two baffles are provided at the upper end of the connecting column. An adjustment cavity is opened on the corresponding side of the two baffles. The inner wall of the adjustment cavity is provided with a soft pad. An extension motor is fixedly connected to one side of one of the baffles.

[0006] Preferably, the two baffles are slidably connected to the upper end of the connecting column, the upper end of the connecting column is provided with a plurality of threaded grooves, and the plurality of threaded grooves are evenly arranged, and the upper end of the other baffle is provided with a downward limiting groove, and the inner wall of the limiting groove is provided with a threaded post that cooperates with the threaded groove.

[0007] Preferably, the soft pad is fitted and connected to the inner wall of the adjustment cavity, and a supporting elastic element is fixedly connected to one end of the soft pad located on the inner wall of the adjustment cavity. The end of the supporting elastic element away from the soft pad is fixedly connected to the inner wall of the adjustment cavity, and the soft pad is fixedly connected to the inner wall of the adjustment cavity through the supporting elastic element.

[0008] Preferably, the threaded post is threaded through the upper end of the limiting groove and extends to the inner wall of the threaded groove, and the threaded post is located in close contact with the inner wall of the threaded groove.

[0009] Preferably, the right stiffener plate auxiliary installation platform is slidably connected to the upper end of the mounting base, and a telescopic servo motor is fixedly connected to the side of the right stiffener plate auxiliary installation platform that is close to the mounting base. The end of the telescopic servo motor that is away from the right stiffener plate auxiliary installation platform is fixedly connected to the side of the telescopic servo motor, and the side of the right stiffener plate auxiliary installation platform that is away from the telescopic servo motor is close to the connecting column.

[0010] Preferably, the lower end of the movable welding clamp is fixedly connected to a limiting seat, one side of the limiting seat is fitted into one end of the left stiffening plate auxiliary installation platform, and a connecting cylinder is fixedly connected to the side of the movable welding clamp close to the limiting seat. The movable welding clamp is fitted into the side of the left stiffening plate auxiliary installation platform corresponding to the welding turntable through the limiting seat.

[0011] Preferably, the lower base welding slide is fixedly connected to the side of the robot body corresponding to the lower base welding slide via a connecting seat, and the length of the connecting seat is adapted to the length of the lower base welding slide.

[0012] Preferably, there are two clamps, which are symmetrically arranged at both ends of the welding turntable, and the upper ends of the two clamps are fixedly connected to the bodies of hydraulic cylinders.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] 1. The servo motor pushes the rib plate to move towards the distance between the baffles. At this time, one side of the soft pad and both ends of the rib plate approach each other. The extension motor pushes one of the baffles forward, and the soft pad and the two sides of the rib plate come into contact and wrap around each other to limit the movement. The contact surface between the rib plate and the soft pad generates relative pressure, and the elastic element itself contracts under the force. The elastic element provides elastic support to the side closer to the soft pad, increasing the stability of the limiting position between the soft pad and the rib plate. In addition, the elastic element itself generates a reaction force on the side of the soft pad and the rib plate that is close together, which... The stiffening plate acts as a buffer, increasing the adaptive force between the soft pad and the contact surface of the stiffening plate, reducing the contact gap between the stiffening plate and the soft pad, and thus improving the flexibility of fixing the stiffening plate within the device. This achieves high efficiency in the installation of the stiffening plate and enhances the protective performance during installation. Under the action of the fixing device, the correct position of the stiffening plate is ensured. At this time, the clamp extends to clamp the stiffening plate and the arc plate. The moving welding clamp moves laterally under the drive of the connecting cylinder to complete the pre-tack welding of the stiffening plate and the arc plate, thereby improving the automatic welding efficiency of the device and facilitating the high efficiency of automatic assembly welding of the electrode shell.

[0015] 2. By setting up baffles in conjunction with threaded posts and threaded grooves, before moving the rib plate, the user rotates the threaded post upwards on the inner wall of the threaded groove, causing the baffle at the upper end of the connecting post to loosen. At this time, the user moves and adjusts the baffle at the upper end of the connecting post. The distance between the two baffles is changed according to the size of the rib plate, thus flexibly adjusting the distance between the two baffles. Once adjusted to a suitable position, the baffle is fixed by the threaded post and threaded groove, facilitating quick fixation of the adjusted position. The threaded fixing method is simple and convenient, easy for the user to operate, and reduces the difficulty of adjustment. At the same time, the baffle distance is freely adjustable, improving the device's ability to install and use rib plates of different sizes, enhancing the device's practicality, and increasing the efficiency of electrode shell assembly welding.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0027] Reference Figure 1-6An automatic electrode shell assembly welding robot includes a lower base welding slide 1, a mounting base 2, and a fixing device 3. A robot body 12 is mounted on one side of the lower base welding slide 1. A welding carriage 13 is movably connected to the side of the lower base welding slide 1 away from the robot body 12. A drive motor 15 is fixedly connected to the upper end of the welding carriage 13, and a welding turntable 14 is movably connected to one end of the drive motor 15. The mounting base 2 is fixedly connected to the upper end of the lower base welding slide 1. A right stiffener auxiliary mounting platform 22 is provided on the upper end of the mounting base 2, and the right stiffener auxiliary mounting platform 22 is fitted into the side of the welding turntable 14 closest to it. A clamp 24 is connected to the lower base welding slide 1, which is fixedly connected to the side away from the mounting base 2. A left stiffening plate auxiliary mounting platform 23 is fixedly connected to the side of the left stiffening plate auxiliary mounting platform 23 corresponding to the welding turntable 14. A movable welding clamp 26 is provided on the side of the left stiffening plate auxiliary mounting platform 23 corresponding to the welding turntable 14. The fixing device 3 includes a connecting column 31, which is welded to the side of the welding cart 13 close to the welding turntable 14. Two baffles 32 are provided at the upper end of the connecting column 31. An adjustment cavity 37 is opened on the side of the two baffles 32 corresponding to each other. A soft pad 39 is provided on the inner wall of the adjustment cavity 37. An extension motor 36 is fixedly connected to one side of one of the baffles 32.

[0028] By setting up the robot body 12 in conjunction with the left and right rib plate auxiliary installation platforms 23 and 22, the robot body 12 suctions the rib plate and places it above the left and right rib plate auxiliary installation platforms 23 and 22 for auxiliary installation. The telescopic servo motor 21 pushes the rib plate to move towards the distance between the baffles 32. At this time, one side of the soft pad 39 and the two ends of the rib plate approach each other. The extension motor 36 pushes one of the baffles 32 forward, and the soft pad 39 and the two sides of the rib plate come into contact and wrap around and limit it. The contact surface between the rib plate and one side of the soft pad 39 generates relative compression force. The elastic element 38 itself is subjected to force and relatively contracts. The elastic element 38 provides elastic support to the side close to the soft pad 39, increasing the stability of the soft pad 39 and the rib plate limit. The elastic element 38 itself provides elastic support to the soft pad 39. 9 generates a reaction force on the side close to the stiffener, which buffers the stiffener, increases the adaptive force between the soft pad 39 and the stiffener, reduces the contact gap between the stiffener and the soft pad 39, and thus improves the flexibility of the stiffener in the device, achieving high efficiency in the installation of the stiffener and enhancing the protective performance during installation. The robot body 12 picks up the arc plate and brings the arc surface of the arc plate close to the side of the welding turntable 14. The lower folded edge of the arc plate contacts the stiffener surface. The telescopic servo motor 21 pushes the stiffener back into the position between the baffles 32. Under the action of the fixing device 3, the correct position of the stiffener is ensured. At this time, the clamp 24 extends to clamp the stiffener and the arc plate. The moving welding clamp 26 moves laterally under the drive of the connecting cylinder 28 to complete the pre-spot welding of the stiffener and the arc plate, thereby improving the automatic welding efficiency of the device and facilitating the high efficiency of the electrode shell in automatic combination welding.

[0029] Furthermore, two baffles 32 are slidably connected to the upper end of the connecting post 31. The upper end of the connecting post 31 is provided with a number of threaded grooves 34, and the number of threaded grooves 34 are evenly arranged. The upper end of the other baffle 32 is provided with a downward limiting groove 33, and the inner wall of the limiting groove 33 is provided with a threaded post 35 that cooperates with the threaded groove 34.

[0030] By setting baffle 32 in conjunction with threaded post 35 and threaded groove 34, before moving the rib plate, the user rotates the threaded post 35 upward on the inner wall of the threaded groove 34, causing the baffle 32 to loosen at the upper end of the connecting post 31. At this time, the user moves and adjusts the baffle 32 at the upper end of the connecting post 31. The distance between the two baffles 32 is changed according to the size of the rib plate, thus flexibly adjusting the distance between the two baffles 32. When adjusted to a suitable position, the threaded post 35 and threaded groove 34 are threaded and fixed, which facilitates quick fixation of the adjusted position of the baffle 32. The threaded fixing method is simple and convenient, easy for the user to operate, and reduces the difficulty of adjustment. At the same time, the distance of the baffle 32 is freely adjustable, which improves the installation and use of rib plates of different sizes, enhances the practicality of the device, and increases the welding efficiency of the electrode shell assembly.

[0031] Furthermore, the soft pad 39 is fitted and connected to the inner wall of the adjustment cavity 37. One end of the soft pad 39 located on the inner wall of the adjustment cavity 37 is fixedly connected to a supporting elastic element 38. The end of the supporting elastic element 38 away from the soft pad 39 is fixedly connected to the inner wall of the adjustment cavity 37. The soft pad 39 is fixedly connected to the inner wall of the adjustment cavity 37 through the supporting elastic element 38.

[0032] The telescopic servo motor 21 pushes the rib plate to move towards the distance between the baffles 32. At this time, one side of the soft pad 39 and both ends of the rib plate approach each other. The extension motor 36 pushes one of the baffles 32 forward. The soft pad 39 and both sides of the rib plate come into contact and wrap around and limit its movement. The contact surface between the rib plate and one side of the soft pad 39 generates relative pressure. The elastic element 38 itself contracts under the force of the elastic force. The elastic element 38 provides elastic support to the side close to the soft pad 39, increasing the stability of the limiting position of the soft pad 39 and the rib plate, and supporting... The elastic element 38 generates a reaction force on the side of the soft pad 39 that is close to the stiffener, which buffers the stiffener, increases the self-adaptive force on the contact surface between the soft pad 39 and the stiffener, reduces the contact gap between the stiffener and the soft pad 39, and thus increases the flexibility of the stiffener in fixing within the device, increases the stability of the stiffener during installation, and avoids damage caused by excessive tightness during fixing or displacement during welding due to excessive looseness of the stiffener. This improves the flexibility of the stiffener in fixing within the device and increases the welding quality of the stiffener.

[0033] Furthermore, the threaded post 35 is threaded through the upper end of the limiting groove 33 and extends to the inner wall of the threaded groove 34. The threaded post 35 is tightly fitted to the inner wall of the threaded groove 34. The threaded fixing method is simple and convenient, reducing the difficulty of user adjustment. According to the user's manual adjustment, it is convenient to adjust the position accurately, so that the baffle 32 is fixed stably at the upper end of the connecting post 31. By adjusting the position of one baffle 32 above the connecting post 31, the relative movement of the baffle 32 can be quick. The other baffle 32 is extended by the extension motor 36 so that the distance between the two baffles 32 is wrapped and limited by the rib plate.

[0034] Furthermore, the right stiffener plate auxiliary installation platform 22 is slidably connected to the upper end of the mounting base 2. A telescopic servo motor 21 is fixedly connected to the side of the right stiffener plate auxiliary installation platform 22 that is close to the mounting base 2. The end of the telescopic servo motor 21 that is away from the right stiffener plate auxiliary installation platform 22 is fixedly connected to the side of the telescopic servo motor 21. The side of the right stiffener plate auxiliary installation platform 22 that is away from the telescopic servo motor 21 is close to the connecting column 31. The telescopic servo motor 21 is a driving element that keeps the device driven.

[0035] Furthermore, a limiting seat 27 is fixedly connected to the lower end of the movable welding clamp 26. One side of the limiting seat 27 is fitted and connected to one end of the left stiffening plate auxiliary installation platform 23. A connecting cylinder 28 is fixedly connected to the side of the movable welding clamp 26 that is close to the limiting seat 27. The movable welding clamp 26 is fitted and connected to the side of the left stiffening plate auxiliary installation platform 23 corresponding to the welding turntable 14 through the limiting seat 27. The robot body 12 picks up the arc plate and brings the arc surface of the arc plate close to the side of the welding turntable 14. The lower folded edge of the arc plate contacts the stiffening plate surface. The telescopic servo motor 21 drives the arc plate to contact the stiffening plate surface. The stiffener plate is pushed back into position between the baffles 32. Under the action of the fixing device 3, the correct position of the stiffener plate is ensured. At this time, the clamp 24 extends to clamp the stiffener plate and the arc plate. The moving welding clamp 26 moves laterally under the drive of the connecting cylinder 28 to complete the pre-tack welding of the stiffener plate and the arc plate. The moving welding clamp 26 returns to its original position, the clamp 24 is released and returns to its original position, the fixing device 3 returns to its original position, the welding carriage turntable rotates an angle, and the above actions are repeated to assemble the stiffener plate and the arc plate, thereby improving the automatic welding efficiency of this device and facilitating the high efficiency of automatic assembly welding of the electrode shell.

[0036] Furthermore, the lower base welding slide 1 is fixedly connected to the robot body 12 on the side corresponding to it by a connecting seat 25, the length of which is adapted to the length of the lower base welding slide 1.

[0037] Furthermore, there are two clamps 24, which are symmetrically arranged at both ends of the welding turntable 14. The upper ends of the two clamps 24 are fixedly connected to the hydraulic cylinder body 29. The two clamps 24 simultaneously clamp the arc plate and the stiffening plate, keeping the arc plate and the stiffening plate on the same horizontal plane, thereby improving the welding quality of the combined device.

[0038] Working Principle: When using this device, the robot body 12, in conjunction with the left rib plate auxiliary installation platform 23 and the right rib plate auxiliary installation platform 22, suctions the rib plate and places it above the left and right rib plate auxiliary installation platforms 23 and 22 for auxiliary installation. The telescopic servo motor 21 pushes the rib plate to move towards the distance between the baffles 32. At this time, one side of the soft pad 39 and the two ends of the rib plate approach each other. The extension motor 36 pushes one of the baffles 32 forward, and the soft pad 39 and the two sides of the rib plate come into contact and wrap around each other to limit the movement. The contact surface between the rib plate and one side of the soft pad 39 generates relative pressure, and the elastic support member 38 contracts under the force. The elastic support member 38 provides elastic support to the side close to the soft pad 39, increasing the stability of the soft pad 39 and the rib plate limitation. The elastic support member 38 itself is elastic. The force generates a reaction force on the side of the soft pad 39 that is close to the rib plate, which buffers the rib plate, increases the adaptive force of the contact surface between the soft pad 39 and the rib plate, reduces the contact gap between the rib plate and the soft pad 39, and thus increases the flexibility of fixing the rib plate in the device, achieving the high efficiency of the device for rib plate installation and improving the protective performance of the rib plate during installation. The robot body 12 picks up the arc plate and brings the arc surface of the arc plate close to the side of the welding turntable 14. The lower folded edge of the arc plate contacts the surface of the rib plate. The telescopic servo motor 21 pushes the rib plate back into the position between the baffles 32. Under the action of the fixing device 3, the correct position of the rib plate is ensured. At this time, the clamp 24 extends to clamp the rib plate and the arc plate. The moving welding clamp 26 moves laterally under the drive of the connecting cylinder 28 to complete the pre-spot welding of the rib plate and the arc plate, thereby improving the automatic welding efficiency of the device and facilitating the high efficiency of the electrode shell in automatic combination welding.

[0039] By setting baffle 32 in conjunction with threaded post 35 and threaded groove 34, before moving the rib plate, the user rotates the threaded post 35 upward on the inner wall of the threaded groove 34, causing the baffle 32 to loosen at the upper end of the connecting post 31. At this time, the user moves and adjusts the baffle 32 at the upper end of the connecting post 31. The distance between the two baffles 32 is changed according to the size of the rib plate, thus flexibly adjusting the distance between the two baffles 32. When adjusted to a suitable position, the threaded post 35 and threaded groove 34 are threaded and fixed, which facilitates quick fixation of the adjusted position of the baffle 32. The threaded fixing method is simple and convenient, easy for the user to operate, and reduces the difficulty of adjustment. At the same time, the distance of the baffle 32 is freely adjustable, which improves the installation and use of rib plates of different sizes, enhances the practicality of the device, and increases the welding efficiency of the electrode shell assembly.
