Description

Technical Field

[0001] The present invention relates to the technical field of welding, and more specifically, to an industrial welding robot with a collision protection component. Background Art

[0002] A welding robot mainly consists of a base, a rotating motor, a rotating shaft, a large arm rod, a small arm rod, and a welding head. The base supports the entire system, and the rotating motor drives the rotating shaft to make the robot rotate. One end of the large arm rod is connected to the base, and the other end is connected to the small arm rod, driving the small arm rod and the welding head to perform multi-dimensional movements. The welding head melts the welding wire by generating a high-temperature arc to form a weld seam with the base material. Some models are equipped with a gas protection system to prevent oxidation. This equipment is used in fields such as automobile manufacturing and ship engineering to achieve efficient welding operations through a preset program.

[0003] With the increasing demand for welding of complex structural parts in the industrial manufacturing field, especially in welding scenarios of enclosed cavities with narrow access channels such as automobile fuel tanks and pressure vessels, when the welding arm of a traditional welding robot works in a confined space, its rigid structure is prone to collide with the cavity wall. At the same time, when the welding torch needs to work in a narrow channel, limited by the size of the robot body, it often cannot directly reach the welding position.

[0004] Based on this, the present invention provides an industrial welding robot with a collision protection component. Summary of the Invention

[0005] In order to solve the problems raised in the above background art, the present invention provides an industrial welding robot with a collision protection component, which realizes linear welding operations in a narrow enclosed space, solves the movement limitations of traditional welding arms in a confined environment, enables the welding torch to independently extend and move along a predetermined trajectory within the cavity, not only maintains the control of the welding path but also avoids the risk of interference between the overall mechanism and the cavity wall.

[0006] The technical solution adopted by the industrial welding robot with a collision protection component provided by the present invention is as follows:

[0007] An industrial welding robot with a collision protection component, including a welding robot, further comprising an adjustment bracket arranged on the welding robot; a welding torch arranged on the adjustment bracket; wherein, the adjustment bracket includes a turntable arranged on the front movable arm of the welding robot; a U-shaped seat arranged at the bottom of the turntable through a connecting piece; an assembly block slidably arranged on the side of the U-shaped seat, and the welding torch is arranged on the side of the assembly block; a rotating plate rotatably arranged on the inner wall of the U-shaped seat, and a driving member for driving the rotating plate to rotate is arranged on the side of the U-shaped seat; a first electric push rod arranged on the top of the rotating plate; the output end of the first electric push rod is connected with a socket, and a plug matched with the socket is arranged on the side of the assembly block, and both the socket and the plug are made of magnets and can be adsorbed and fixed; a magnetic strip block arranged on the side of the U-shaped seat for adsorbing and fixing the assembly block.

[0008] Preferably, the assembly block includes a fixed block and a movable block. A sliding groove is formed on the side of the U-shaped seat, the fixed block is slidably arranged in the sliding groove, and the movable block is movably arranged on the side of the fixed block through a reciprocating component.

[0009] Preferably, the reciprocating component includes a reciprocating rod slidably arranged inside the fixed block. The side end of the reciprocating rod is arranged outside the fixed block, and the movable block is fixedly arranged at the side end of the reciprocating rod. A driving member for driving the driving gear to rotate is arranged inside the fixed block, and two driven gears are symmetrically meshed on the outside of the driving gear. Half-tooth gears are arranged on the tops of the driven gears. When one half-tooth gear meshes with the reciprocating rod, the other half-tooth gear is separated from the reciprocating rod.

[0010] Preferably, a notch is formed on the side of the fixed block, a rotating shaft is rotatably arranged inside the notch, a connecting plate is fixedly arranged on the side of the rotating shaft, a mounting sleeve is rotatably arranged on the side of the connecting plate, and the welding torch is arranged inside the mounting sleeve.

[0011] Preferably, both the rotating shaft and the mounting sleeve are equipped with driving members for driving the welding torch to adjust the angle.

[0012] Preferably, the turntable is rotatably arranged on the front movable arm of the welding robot.

[0013] Preferably, the connecting piece is a second electric push rod.

[0014] Preferably, a collision prevention grid is further arranged on the periphery of the welding robot, and the collision prevention grid is in a C-shaped structure.

[0015] In summary, the present invention has the following beneficial technical effects:

[0016] 1. The adjustment bracket is inserted into the enclosed workpiece with a narrow access passage by a welding robot. Then, the driving member drives the rotating plate to rotate, so that the socket on the first electric push rod aligns with the plug on the assembly block. Next, the first electric push rod extends to insert the socket onto the plug, and the socket and the plug are magnetically adsorbed. Then, the first electric push rod pushes the assembly block to move and separate from the U-shaped seat. Thus, the assembly block drives the welding torch to move in the chamber for linear welding. Through this design, linear welding operation in a narrow enclosed space is achieved, solving the movement limitation of traditional welding arms in a closed environment, enabling the welding torch to independently extend and move along a predetermined trajectory in the chamber, maintaining the control of the welding path while avoiding the interference risk between the overall mechanism and the chamber wall.

[0017] 2. When the welding torch is linearly moving for work, the driving member can also drive the driving gear to rotate, causing the two driven gears to rotate. Thus, the two half-toothed gears rotate, and the reciprocating rod reciprocates back and forth in the fixed block. As a result, the welding torch can perform reciprocating welding back and forth, achieving single-sided double-pass welding. Through this design, double-pass welding coverage of a single weld area is realized, improving the filling rate of the weld cross-sectional area, effectively eliminating defects such as lack of penetration and insufficient fusion depth. At the same time, the interlocking structure formed by the double-pass welds significantly enhances the fatigue strength of the joint surface.

[0018] 3. The rotating shaft drives the connecting plate and the mounting sleeve to rotate, enabling the welding torch to perform welding operations on a circular track.

[0031] Embodiment 1

[0032] The embodiment of the present invention discloses an industrial welding robot with a collision protection component. Referring to Figures 1 to 4 , an industrial welding robot with a collision protection component includes a welding robot 1, an adjusting bracket 3 and a welding torch 2; the adjusting bracket 3 is arranged on the welding robot 1; the welding torch 2 is arranged on the adjusting bracket 3.

[0033] As Figure 1 shown, it further includes an anti-collision grid frame 4 arranged on the periphery of the welding robot 1. The anti-collision grid frame 4 is in a U-shaped structure. By arranging the anti-collision grid frame 4, during the operation of the welding robot 1, the anti-collision grid frame 4 can provide collision protection for it, avoiding external objects from colliding with the welding robot 1 during operation.

[0034] Among them, the adjusting bracket 3 includes a turntable 30, a U-shaped seat 31, an assembly block 32, a rotating plate 33, an electric push rod one 34 and a magnetic strip block 37.

[0035] The turntable 30 is arranged on the front movable arm of the welding robot 1; the U-shaped seat 31 is arranged at the bottom of the turntable 30 through a connecting piece; the assembly block 32 is slidably arranged on the side of the U-shaped seat 31, and the welding torch 2 is arranged on the side of the assembly block 32; the rotating plate 33 is rotatably arranged on the inner wall of the U-shaped seat 31, and a driving part for driving the rotating plate 33 to rotate is arranged on the side of the U-shaped seat 31; the first electric push rod 34 is arranged on the top of the rotating plate 33; the output end of the first electric push rod 34 is connected with a socket 35, and a plug 36 which is matched with the socket 35 is arranged on the side of the assembly block 32, and both the socket 35 and the plug 36 are made of magnets and can be adsorbed and fixed; a magnetic strip block 37 is arranged on the side of the U-shaped seat 31 for adsorbing and fixing the assembly block 32.

[0036] The adjustment bracket 3 is inserted into a sealed workpiece with a narrow access passage (such as a fuel tank cavity, etc.) through the welding robot 1, and then the driving part drives the rotating plate 33 to rotate, so that the socket 35 on the first electric push rod 34 is aligned with the plug 36 on the assembly block 32. Then the first electric push rod 34 extends so that the socket 35 is inserted into the plug 36, and the socket 35 and the plug 36 are magnetically adsorbed. Then the first electric push rod 34 pushes the assembly block 32 to move away from the U-shaped seat 31. Thus, the welding torch 2 driven by the assembly block 32 moves in the chamber for linear welding.

[0037] Through this design, linear welding operation in a narrow and sealed space is realized, the movement limitation of the traditional welding arm in a sealed environment is solved, and the welding torch 2 can independently extend and move along a predetermined track in the chamber, which not only maintains the control of the welding path but also avoids the interference risk between the overall mechanism and the chamber wall.

[0038] Specifically, the turntable 30 is rotatably arranged on the front movable arm of the welding robot 1. This design can increase the flexibility of the welding torch 2.

[0039] Specifically, the connecting piece is the second electric push rod 38, and the position of the welding torch 2 can also be adjusted through the second electric push rod 38.

[0040] Embodiment 2

[0041] This embodiment is further optimized on the basis of the above-mentioned Embodiment 1. The same parts as the foregoing technical solutions will not be described herein again. For example Figure 5 And Figure 6 As shown, in order to better implement the present invention, the following setting method is particularly adopted. In this embodiment, the assembly block 32 includes a fixed block 320 and a movable block 321. A sliding groove 322 is formed on the side of the U-shaped seat 31, the fixed block 320 is slidably arranged in the sliding groove 322, and the movable block 321 is movably arranged on the side of the fixed block 320 through a reciprocating assembly.

[0042] Such as Figure 7 And Figure 8As shown in the figure, the reciprocating component includes a reciprocating rod 323 slidably arranged inside the fixed block 320. The side end of the reciprocating rod 323 is arranged outside the fixed block 320, and the moving block 321 is fixedly arranged at the side end of the reciprocating rod 323. A driving gear 324 is rotatably arranged inside the fixed block 320, and a driving member for driving the driving gear 324 to rotate is arranged inside the fixed block 320. Two driven gears 325 are symmetrically meshed on the outside of the driving gear 324, and half-tooth gears 326 are arranged on the tops of the driven gears 325. When one half-tooth gear 326 meshes with the reciprocating rod 323, the other half-tooth gear 326 is separated from the reciprocating rod 323.

[0043] Specifically, when the welding torch 2 linearly moves for work, the driving member can also drive the driving gear 324 to rotate, so that the two driven gears 325 rotate. Thus, the two half-tooth gears 326 rotate, so that the reciprocating rod 323 reciprocates back and forth inside the fixed block 320. Thereby, the welding torch 2 can perform reciprocating welding back and forth, realizing single-sided double-pass welding. Through this design, double-pass welding coverage of a single weld area is achieved, the filling rate of the weld cross-sectional area is improved, and defects such as lack of penetration and insufficient fusion depth are effectively eliminated. At the same time, the interlocking structure formed by the double-pass welds greatly enhances the fatigue strength of the bonding surface.

A connecting plate 327 is fixedly arranged on the side surface of the rotating shaft. An installation sleeve 328 is rotatably arranged on the side surface of the connecting plate 327. The welding torch 2 is arranged inside the installation sleeve 328.

[0046] For example Figure 5 And Figure 6 As shown in the figure, both the rotating shaft and the installation sleeve 328 are equipped with driving members for driving the welding torch 2 to perform angle adjustment.

[0047] Specifically, by driving the connecting plate 327 to rotate and the installation sleeve 328 to rotate through the rotating shaft, the welding torch 2 can perform welding operations on an annular track.
