Description

Technical Field

[0001] The invention belongs to the technical field of welding robots, in particular to an industrial welding robot. Background Art

[0002] As a common processing method in modern manufacturing, welding technology is widely used in steel structure, automobile manufacturing, shipbuilding, machinery and equipment manufacturing and other industries. With the continuous development of technology and the improvement of automation level, welding robots, as efficient equipment to replace manual welding, have been increasingly put into industrial production. Traditional manual welding has a harsh working environment, high work intensity, and is easily affected by human factors, resulting in fluctuations in welding quality. The use of welding robots can not only improve the working environment and reduce labor intensity, but also provide stable and consistent welding quality.

[0003] Chinese patent CN109807509A discloses an industrial welding robot, which can make welding accuracy more accurate through the function of a supporting device, and can change the welding angle through the function of an adjusting device, so as to achieve multi-angle operation. However, when performing steel welding work, in order to ensure that there is no problem of steel dislocation and separation during the welding process, the steel needs to be fixed and set to ensure that the strength of the finished steel is large enough. If the welded steel needs to maintain a certain deflection angle, the points in the fixed state cannot effectively clamp and fix the steel, and the steel is heavy, and it is difficult to repeatedly adjust the steel manually, so it is necessary to design a more convenient welding equipment. Summary of the invention

[0006] The deflection device includes a guide bottom ring, and sliding shells are symmetrically arranged on the left and right sides of the outer surface of the guide bottom ring. The bottom sliding connection of the inner wall of the sliding shell is connected to a limiting suction cup.

[0007] Furthermore, the welding equipment includes a parallel sliding plate, and limiting spring belts are evenly arranged on the sides of the parallel sliding plate. A pressure push rod is slidably connected to the axis of the inner wall of the parallel sliding plate, and a spring washer is sleeved on the outer surface of the pressure push rod. The bottom end of the pressure push rod is fixedly connected to a welding end, and monitoring cameras are evenly arranged on the lower part of the outer surface of the pressure push rod.

[0008] Furthermore, the outer surface of the parallel sliding plate is slidably connected to the inner cavity of the limiting rotating plate through a transfer groove, one end of the limiting spring belt is fixedly connected to the side of the parallel sliding plate, and the other end of the limiting spring belt is fixedly connected to the inner cavity of the limiting rotating plate through the transfer groove. The bottom end of the spring washer is fixedly connected to the upper surface of the parallel sliding plate, and a guide bottom ring and sliding shells on both sides are provided in the middle of the fixed base and the middle of the limiting rotating plate to ensure that the upper and lower sides of the welding plate can perform clamping and limiting work.

[0009] Furthermore, the number of the deflection devices is two, the lower surface of the guide bottom ring is fixedly connected to the upper surface of the induction disk, the lower surface of the sliding shell is slidably connected to the outer surface of the guide bottom ring through a slot, the inner cavity of the sliding shell is provided with a welded steel bar, the top of the limit suction cup and the outer surface of the welded steel bar are mutually squeezed, and the inner wall of the deflection clamp is clamped with the outer surface of the sliding shell. The bottom end of the deflection clamp is rotatably connected to the upper surface of the fixed base through a rotating groove, the outer surface of the induction disk is fixedly connected to the middle of the inner cavity of the fixed base, the upper surface of the induction disk is evenly provided with scale grooves, and the outer surface of the deflection clamp is slidably connected to the upper surface of the induction disk through the scale grooves.

[0010] Furthermore, the buffer stopper comprises an axis base, arc-shaped sliding shells are symmetrically arranged on both sides of the inner cavity of the axis base, a compression spring is fixedly connected to the inner wall of the arc-shaped sliding shell, and a pressure-sensitive column is fixedly connected to one end of the compression spring away from the arc-shaped sliding shell. The bottom end of the axis base is fixedly connected to the middle part of the upper surface of the guide bottom ring, and the upper and lower ends of the pressure-sensitive column are fixedly connected to the inner cavity of the axis base through a fixed plug rod, and one end of the arc-shaped sliding shell away from the pressure-sensitive column extends to the outside of the axis base through a through-notch, and the outer surface of the arc-shaped sliding shell is slidably connected to the inner wall of the axis base through the through-notch.

[0011] Furthermore, the drainage device includes a docking bellows, the top of the inner cavity of the docking bellows is evenly provided with suction grooves, and the docking bellows can continuously perform suction work from above through the suction grooves. An extended outer shaft is fixedly connected to the axis of the upper surface of the docking bellows, and parallel frames are symmetrically arranged on both sides of the top of the extended outer shaft. Parallel searchlights are evenly arranged on the top of the parallel frames, and the parallel searchlights are directly opposite to the sides of the welded steel bars, and the top of the parallel frames is flush with the middle of the welded steel bars.

[0012] Furthermore, the outer surface of the docking bellows is fixedly connected to the axis of the inner wall of the induction disk, the outer surface of the parallel frame plate is fixedly connected to the middle of the outer surface of the axis base on the side away from the extended outer axis, and the outer surface of the parallel searchlight is fixedly connected to the top of the parallel frame plate through a slot.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. When using a welding robot to weld two sections of steel, if the welded steel needs to maintain a certain deflection angle, the fixed point cannot effectively clamp and fix the steel, and the steel is heavy, so it is difficult to adjust the steel repeatedly manually. The device can fix the two sections of steel bars through the sliding shells on both sides. Since the sliding shell can deflect around the guide bottom ring under the action of the deflection clamp, the device can freely change the angle between the welding points of the steel bars while fixing the steel bars, and accurately control the angle of the steel bars on both sides through the scale grooves of the induction disk, thereby quickly realizing the angle welding of the steel bars, avoiding the problem of difficulty in repeatedly adjusting the steel, and improving welding efficiency and welding accuracy.

[0015] 2. When the welding equipment of the device is used to spot weld the clamped welding steel bars, since the parallel slide can slide freely inside the transfer trough and the internal welding points are monitored by the monitoring camera, the strong light generated by welding will not hurt the eyes of the operator, and the welding end always remains perpendicular to the parallel slide, and the clamped welding steel bar can remain parallel to the limit turn plate under the adjustment of the limit suction cup, so the welding end is always perpendicular to the welding steel bar, thereby ensuring that the landing point of the welding end will never be tilted with the weld, ensuring that the solder can act completely on the weld, and improving the fixing effect of the welding.

[0016] 3. In the process of the sliding shells on both sides performing deflection and sliding movement around the guide bottom ring, in order to prevent the deflection clamping plate from causing the sliding shell to collide, a buffer stopper is set in the middle of the guide bottom ring to prevent the sliding shell from contacting each other, and before the side of the sliding shell contacts and collides with the outer surface of the axis base, the arc-shaped sliding shells on both sides will first be squeezed by the sliding shell and shrink toward the inside of the axis base, and then the pressure-sensitive column in the middle is pressed by the compression spring to trigger the pressure-sensitive column to prevent the deflection clamping plate from continuing to deflect, thereby playing a blocking role and avoiding the problem of overload of the bottom wheel motor caused by continuous movement of the deflection clamping plate.

[0017] 4. When welding, the docking bellows located below absorbs the sparks and toxic fumes generated by welding downwards through the suction grooves to avoid spreading to the outside and polluting the production environment, thereby ensuring green production. Since the parallel frames on both sides are symmetrically arranged on both sides of the sliding shell, and the sliding shell cannot move to the position of the buffer stopper, the upper and lower limit suction cups can monitor the actual state of the steel bar through the parallel searchlight of the parallel welding steel bar when clamping the welding steel bar, thereby avoiding the problem of the steel bar tilting and the inability to weld smoothly.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: an industrial welding robot comprises a container 1 when welding two sections of steel. The container 1 comprises a fixed base 11. The back of the fixed base 11 is rotatably connected with a joint rotating rod 12. The outer surface of the joint rotating rod 12 is rotatably connected with a limited rotating plate 13 on a side away from the fixed base 11. When the limited rotating plate 13 and the fixed base 11 are clamped and closed, the limited rotating plate 13 and the fixed base 11 remain parallel to each other. A transfer groove 14 is provided in the inner cavity of the limited rotating plate 13, and a welding device 2 is arranged inside the transfer groove 14; an induction plate 15 is arranged in the middle of the inner wall of the fixed base 11, a drainage device 4 is arranged in the middle of the inner wall of the induction plate 15, a deflection device 3 is arranged on the upper surface of the induction plate 15, and a deflection clamping plate 17 is symmetrically arranged on the outer surface of the induction plate 15 through the rotating groove. Under the action of the active rotating wheel, the bottom end of the deflection clamping plate 17 can rotate and slide around the induction plate 15 along the circular groove of the fixed base 11;

[0028] The deflection device 3 includes a guide bottom ring 31, and a sliding shell 32 is symmetrically arranged on the left and right sides of the outer surface of the guide bottom ring 31. The bottom sliding connection of the inner wall of the sliding shell 32 is provided with a limiting suction cup 33. Under the action of the bottom end connecting rod, the limiting suction cup 33 can be pushed toward one side of the bonding welding component to perform adsorption, clamping and limiting work. The front and rear sides of the outer surface of the sliding shell 32 are symmetrically arranged with docking rods 34, and the front and rear sides of the upper surface of the guide bottom ring 31 are symmetrically arranged with buffer stops 35.

[0029] The welding equipment 2 includes a parallel sliding plate 21, and a limiting spring belt 22 is evenly arranged on the side of the parallel sliding plate 21. A pressure push rod 23 is slidably connected to the axis of the inner wall of the parallel sliding plate 21. A spring washer 24 is sleeved on the outer surface of the pressure push rod 23. The bottom end of the pressure push rod 23 is fixedly connected to a welding end 25, and a monitoring camera 26 is evenly arranged on the lower part of the outer surface of the pressure push rod 23.

[0030] The outer surface of the parallel sliding plate 21 is slidably connected to the inner cavity of the limiting rotating plate 13 through the transfer groove 14, one end of the limiting spring belt 22 is fixedly connected to the side of the parallel sliding plate 21, and the other end of the limiting spring belt 22 is fixedly connected to the inner cavity of the limiting rotating plate 13 through the transfer groove 14. The bottom end of the spring washer 24 is fixedly connected to the upper surface of the parallel sliding plate 21. A guide bottom ring 31 and sliding shells 32 on both sides are provided in the middle of the fixed base 11 and the middle of the limiting rotating plate 13 to ensure that the upper and lower sides of the welding plate can perform clamping and limiting work.

[0031] There are two deflection devices 3. The lower surface of the guide bottom ring 31 is fixedly connected to the upper surface of the induction disc 15. The lower surface of the sliding shell 32 is slidably connected to the outer surface of the guide bottom ring 31 through a slot. The inner cavity of the sliding shell 32 is provided with a welded steel bar 5. The top of the limit suction cup 33 and the outer surface of the welded steel bar 5 are mutually pressed. The inner wall of the deflection clamping plate 17 is clamped with the outer surface of the sliding shell 32. The bottom end of the deflection clamping plate 17 is rotatably connected to the upper surface of the fixed base 11 through a rotating groove. The outer surface of the induction disc 15 is fixedly connected to the middle of the inner cavity of the fixed base 11. The upper surface of the induction disc 15 is evenly provided with scale grooves 16. The outer surface of the deflection clamping plate 17 is slidably connected to the upper surface of the induction disc 15 through the scale grooves 16.

[0032] After rotating and opening the limit rotating plate 13, place the two sections of steel bars to be welded in the sliding shells 32 on both sides, and then cover the limit rotating plate 13 on the fixed base 11. At this time, the sliding shells 32 on the upper and lower sides are merged together through the docking rods 34, and the outer surface of the steel bar is covered. The outer surface of the steel bar is initially clamped and limited by the internal limit suction cup 33. Since the other end of the steel bar extends to the outside of the device, the welding points of the steel bars on both sides can be merged together by pushing the steel bar, and then the steel bar is fixed and clamped by the limit suction cup 33, ready for welding.

[0033] Directly above, the relevant robotic arm drives the parallel slide 21 to move parallel to the transfer groove 14 of the limit turn plate 13 by pulling the pressure push rod 23, adjusts the actual landing point of the welding end 25, and then presses the pressure push rod 23 downward to make the welding end 25 perform hot welding on the welding point of the steel bar. The monitoring camera 26 on the side is used for calibration to monitor the welding work of the steel bar. After welding is completed, the pressure push rod 23 is released. At this time, under the elastic force of the limit spring belt 22 and the spring washer 24, the welding equipment 2 as a whole automatically resets.

[0034] If the two ends of the steel bars to be welded need to maintain a certain angle, after the limiting suction cup 33 preliminarily clamps and limits the steel bars, the deflection clamps 17 on both sides are deflected around the scale groove 16 under the action of the bottom roller. At this time, the deflection clamp 17 will drive the sliding shell 32 at the corresponding position to deflect the sliding shell 32 around the guide bottom ring 31. Since the deflection clamp 17 rotates around the scale groove 16 on the sensing disk 15, the angle between the deflection clamps 17 on both sides can be determined through the point position of the scale groove 16 on the sensing disk 15, thereby indirectly measuring the angle between the steel bars on both sides. After determining the angle of the steel bars, fixation and clamping are performed, and the above-mentioned welding work can be performed.

[0035] Example 2, please refer to Figure 6-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, if toxic smoke is generated during welding, and the steel is prone to tilting and the operator cannot observe it with the naked eye, the buffer stopper 35 includes a shaft base 351, arc-shaped sliding shells 353 are symmetrically arranged on both sides of the inner cavity of the shaft base 351, and the inner wall of the arc-shaped sliding shell 353 is fixedly connected with a compression spring 354, and one end of the compression spring 354 away from the arc-shaped sliding shell 353 is fixedly connected with a pressure-sensitive column 352. The bottom end of the shaft base 351 is fixedly connected to the middle of the upper surface of the guide bottom ring 31, and the upper and lower ends of the pressure-sensitive column 352 are fixedly connected to the inner cavity of the shaft base 351 through a fixed plug rod, and one end of the arc-shaped sliding shell 353 away from the pressure-sensitive column 352 extends to the outside of the shaft base 351 through a through notch, and the outer surface of the arc-shaped sliding shell 353 is slidably connected to the inner wall of the shaft base 351 through the through notch.

[0036] The drainage device 4 includes a docking bellows 41, and the top of the inner cavity of the docking bellows 41 is evenly provided with suction grooves 42. The docking bellows 41 can continuously perform suction work from above through the suction grooves 42. An extended outer shaft 43 is fixedly connected to the axis center of the upper surface of the docking bellows 41. Parallel frames 44 are symmetrically arranged on both sides of the top of the extended outer shaft 43. Parallel searchlights 45 are evenly arranged on the top of the parallel frames 44. The parallel searchlights 45 are directly opposite to the side of the welded steel bar 5, and the top of the parallel frames 44 is flush with the middle of the welded steel bar 5.

[0037] The outer surface of the docking bellows 41 is fixedly connected to the axis of the inner wall of the induction disk 15, the outer surface of the parallel frame plate 44 is fixedly connected to the middle of the outer surface of the axis base 351 on the side away from the extended outer axis 43, and the outer surface of the parallel searchlight 45 is fixedly connected to the top of the parallel frame plate 44 through a slot.

[0038] In the process of the sliding shells 32 on both sides performing deflection and sliding movement around the guide bottom ring 31, in order to prevent the deflection clamp 17 from causing the sliding shell 32 to collide, a buffer stopper 35 is set in the middle of the guide bottom ring 31 to prevent the sliding shell 32 from contacting, and before the side of the sliding shell 32 contacts and collides with the outer surface of the axial base 351, the arc-shaped sliding shells 353 on both sides will first be squeezed by the sliding shell 32. Force, shrink toward the inside of the axial base 351, and then press the middle pressure-sensitive column 352 through the compression spring 354 to trigger the pressure-sensitive column 352 to prevent the deflection clamp 17 from continuing to deflect.

[0039] When welding is in progress, the docking bellows 41 located below absorbs the sparks and toxic fumes generated by welding downwards through the suction grooves 42 to prevent them from spreading to the outside. Since the parallel frames 44 on both sides are symmetrically arranged on both sides of the sliding shell 32, and the sliding shell 32 cannot move to the position where the buffer stopper 35 is located, the upper and lower limit suction cups 33 can monitor the actual state of the steel bar through the parallel searchlight 45 parallel to the welding steel bar 5 when clamping the welding steel bar 5.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
