Description

Technical Field

[0001] This application relates to the field of anti-collision beam processing, and in particular to an anti-collision beam roll welding device. Background Technology

[0002] Anti-collision beams, also known as anti-collision steel beams, are an important component of the passive safety structure of automobiles.

[0003] Existing crash beams (such as) Figure 1 As shown, steel plate 1 is bent and then welded to both ends to form a groove 2 in the middle to provide stress relief for the deformation of the anti-collision beam. To facilitate welding, the welding position of the anti-collision beam is usually set in the groove 2. The welding roller is inserted into the groove 2 and the two ends of steel plate 1 are welded and fixed by the welding roller. However, the width of the groove 2 is different when producing different models of anti-collision beams. When the width of the groove 2 is smaller than the width of the welding roller, the welding roller cannot be properly inserted into the groove 2. Summary of the Invention

[0004] To facilitate the welding of anti-collision beams with different groove widths, this application provides an anti-collision beam roll welding device.

[0005] The anti-collision beam welding device provided in this application adopts the following technical solution: A collision avoidance beam welding device includes a body with a receiving platform and a receiving mechanism mounted on the platform. The receiving mechanism is used to receive bent steel plates. A welding roller is mounted above the receiving mechanism on the body and is rotatably mounted on the body. The welding roller includes a body part and a welding part. The body part is rotatably mounted on the body, and the welding part is detachably sleeved outside the body part. The welding part is composed of several arc rings connected end to end. A fixing component is provided between the arc rings and the body part. The fixing component includes a rod and a slot. There are several rods, which are respectively fixed on several arc rings. The slots are opened around the body part corresponding to the arc rings, and the rods are inserted and fixed in the slots.

[0006] By adopting the above technical solution, and by replacing the welding parts with different thicknesses, the welding device can be adapted to grooves of different widths, thus facilitating the welding of anti-collision beams with different groove widths; compared with directly replacing the welding rollers, replacing the welding parts can save costs; the arc ring can be directly installed on the main body without disassembling the main body to fit the welding parts, which facilitates the disassembly and assembly of the welding parts; the arc ring can be fixed on the main body by using a plug rod and a slot, which facilitates the installation of the arc ring.

[0007] Optionally, an anti-detachment component is provided between the insertion rod and the main body. The anti-detachment component includes an anti-detachment rod and an anti-detachment groove. The anti-detachment rod is slidably disposed within the main body, and the anti-detachment groove is formed on the side wall of the insertion rod. The anti-detachment rod is inserted into the anti-detachment groove by sliding.

[0008] By adopting the above technical solution, the anti-detachment component can prevent the insertion rod from detaching from the slot after the arc ring is installed, thereby reducing the probability of the arc ring falling off.

[0009] Optionally, a drive ring is installed on the main body, and the drive ring is rotatably disposed on the main body, driving the anti-detachment rod to slide.

[0010] By adopting the above technical solution, the drive ring can be set up to facilitate the simultaneous sliding insertion of all anti-detachment rods into the anti-detachment groove.

[0011] Optionally, a reinforcing assembly is provided between the connection point of the adjacent arc rings and the main body. The reinforcing assembly includes a drive rod, a reinforcing rod, and a reinforcing groove. The drive rod is slidably disposed within the main body. The reinforcing rod is fixed on the drive rod. Two reinforcing rods are fixed on the drive rod. There are two reinforcing grooves, which are respectively opened on the adjacent arc rings. The drive rod slides to drive the two reinforcing rods to be inserted into the two reinforcing grooves respectively.

[0012] By adopting the above technical solution, the reinforcement components can strengthen the connection between the connected arc rings, thereby reducing the probability that the gap between the arc rings will widen and affect the welding.

[0013] Optionally, a plurality of wedge-shaped blocks are fixed on the drive ring, the drive rod abuts against the wedge-shaped surface of the wedge-shaped blocks, and the anti-disengagement rod abuts against the horizontal surface of the wedge-shaped blocks.

[0014] By adopting the above technical solution, the wedge block can drive the reinforcing rod through the wedge surface and the anti-detachment rod through the plane, which facilitates the driving of the reinforcing rod and the anti-detachment rod.

[0015] Optionally, a return spring is provided between the reinforcing rod and the main body, the return spring driving the reinforcing rod to slide towards the center of the main body, and an elastic member is provided between the anti-disengagement rod and the main body, the elastic force of the elastic member driving the anti-disengagement rod to slide away from the slot.

[0016] By adopting the above technical solution, the return spring can work with the wedge block to reset the reinforcing rod, and the elastic element can work with the wedge block to reset the anti-disengagement rod.

[0017] Optionally, the drive ring is embedded in the body portion, and a lever is fixed on the drive ring, the lever being flush with the side wall of the body portion.

[0018] By adopting the above technical solution, the setting of the paddle can easily drive the drive ring to rotate. At the same time, the paddle, which is flush with the main body, reduces the influence of the paddle on the rotation of the main body and also reduces the probability of external force driving the gripper.

[0019] Optionally, a stabilizing component is provided between adjacent arc rings. The stabilizing component includes a stabilizing plug and an anti-detachment plug. The stabilizing plug is slidably disposed at the end of one of the arc rings and is inserted into or detached from the other arc ring by sliding. The anti-detachment plug is slidably disposed at the end of the other arc ring and is inserted into the stabilizing plug by sliding.

[0020] By adopting the above technical solution, the setting of the stabilizing component can improve the stability of adjacent arc rings and reduce the probability of arc rings falling off and affecting the roll welding.

[0021] Optionally, the two reinforcing rods on the drive rod are of different lengths, one long and one short. The longer reinforcing rod is inserted into one arc ring to drive the stabilizing block to slide into the other arc ring, and the shorter reinforcing rod is inserted into the other arc ring to drive the anti-detachment slider to slide into the stabilizing block.

[0022] By adopting the above technical solution, the use of the reinforcement rod in conjunction with the stabilizing component can be achieved by triggering the use of the stabilizing component while using the reinforcement component, thus achieving the stabilizing effect of the stabilizing component without affecting normal disassembly and assembly.

[0023] Optionally, the receiving mechanism includes a base plate and side plates. The base plate is fixed on the receiving platform. There are two side plates, which are respectively arranged on both sides of the base plate along its length. Ball bearings are embedded in both the side of the base plate facing the welding roller and the side of the two side plates facing each other.

[0024] By adopting the above technical solution, the anti-collision beam is supported by the base plate and guided by two side plates, making the conveying of the anti-collision beam smoother. The setting of the ball bearings can reduce the friction generated during the conveying of the anti-collision beam and reduce the friction loss of the anti-collision beam during the conveying process.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By replacing the welding parts with different thicknesses, the welding device can be adapted to grooves of different widths, thus facilitating the welding of anti-collision beams with different groove widths; compared to directly replacing the welding rollers, replacing the welding parts can save costs. The arc ring can be directly installed on the main body without disassembling the main body and then fitting the welding part, which facilitates the assembly and disassembly of the welding part. The arc ring can be directly installed on the main body without disassembling the main body and then fitting the welding part, which facilitates the assembly and disassembly of the welding part. The anti-detachment component can prevent the insert from coming out of the slot after the arc ring is installed, thereby reducing the probability of the arc ring falling off. The reinforcement components can strengthen the connection between adjacent arc rings, thereby reducing the probability that the gap between the arc rings will widen and affect the welding. The anti-collision beam is supported by a base plate and guided by two side plates, making the conveying of the anti-collision beam smoother. The ball bearings reduce the friction generated during the conveying of the anti-collision beam and reduce friction loss during the conveying process. Attached Figure Description

Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] This application discloses a crash beam welding device, referring to... Figure 2 and Figure 3 The system includes a rectangular machine body 3 placed on the ground, a receiving platform 4 on the machine body 3, a receiving mechanism 5 mounted on the receiving platform 4, the receiving mechanism 5 being used to receive the bent steel plate 1, a lead screw slide 6 mounted above the receiving mechanism 5 on the machine body 3, an installation platform 7 sliding on the lead screw slide 6, and welding rollers 8 mounted on the installation platform 7. Both the receiving platform 4 and the welding rollers 8 are connected to a power source to supply current, and the bent steel plate 1 is welded through the resistance heating effect. The welding rollers 8 are rotatably mounted on the installation platform 7. The welding roller 8 is rotatably mounted on the machine body 3 via the mounting platform 7 and the lead screw slide 6. The welding roller 8 includes a main body 81 and a welding part 82. The main body 81 is rotatably mounted on the mounting platform 7 and rotates by being mounted on the machine body 3. The welding part 82 is detachably sleeved on the outside of the main body 81. By replacing the welding part 82 with different thicknesses, the welding device can be adapted to grooves 2 of different widths, thereby facilitating the welding of anti-collision beams with different groove widths. Compared with directly replacing the welding roller 8, replacing the welding part 82 can save costs.

[0035] Reference Figure 2 , Figure 3 and Figure 4The welding part 82 is composed of several arc rings 821 connected end to end. In this embodiment, four welding parts 82 are provided, and the four welding parts 82 are connected end to end to form a ring-shaped welding part 82. The welding parts 82 can be assembled without disassembling the main body 81 and then fitting the welding parts 82. By directly attaching and detaching the multiple arc rings 821 on the main body 81, the assembly and disassembly of the welding parts 82 are facilitated. A fixing component 9 is provided between the arc rings 821 and the main body 81. The fixing component 9 includes... The device includes a rod 91 and a slot 92. There are several rods 91. In this embodiment, four rods 91 are provided corresponding to the arc rings 821. The four rods 91 are fixed on the four arc rings 821 respectively. The slots 92 are evenly opened around the body part 81 corresponding to the arc rings 821. In this embodiment, four slots 92 are opened. The rods 91 are inserted and fixed in the slots 92. By using the rods 91 and the slots 92, the arc rings 821 can be fixed on the body part 81, which facilitates the installation of the arc rings 821.

[0036] Reference Figure 2 , Figure 3 and Figure 4 An anti-detachment component 10 is provided between the insertion rod 91 and the main body 81. The anti-detachment component 10 includes an anti-detachment rod 101 and an anti-detachment groove 102. The anti-detachment rod 101 is slidably disposed within the main body 81, and the anti-detachment groove 102 is formed on the side wall of the insertion rod 91. The anti-detachment rod 101 is inserted into the anti-detachment groove 102 by sliding. The anti-detachment component 10 can prevent the insertion rod 91 from disengaging from the slot 92 after the arc ring 821 is installed, thereby reducing the probability of the arc ring 821 falling off. A drive ring 11 is installed on the main body 81 and is rotatably disposed within the main body 81. The anti-detachment component 10 has four wedge blocks 12 fixedly installed. One side plane of the wedge block 12 abuts against the anti-detachment rod 101. The anti-detachment rod 101 is slidably inserted into the anti-detachment groove 102 by the rotation of the drive ring 11. An elastic member 13 is provided between the anti-detachment rod 101 and the main body 81. The elastic member 13 is a compression spring. The elastic force of the elastic member 13 drives the anti-detachment rod 101 to slide away from the slot 92. When the drive ring 11 rotates and drives the wedge block 12 away from the anti-detachment rod 101, the anti-detachment rod 101 slides away from the anti-detachment groove 102 under the elastic force of the elastic member 13.

[0037] Reference Figure 2 , Figure 3 and Figure 5A reinforcing assembly 14 is provided between the connection point of adjacent arc rings 821 and the main body 81. In this embodiment, there are four arc rings 821 and four connection points of adjacent arc rings 821, corresponding to four sets of reinforcing assemblies 14. The reinforcing assembly 14 includes a drive rod 141, reinforcing rods 142, and reinforcing grooves 143. The drive rod 141 is slidably disposed within the main body 81, and the reinforcing rods 142 are fixedly disposed on the drive rod 141. Two reinforcing rods 142 are fixedly disposed on the drive rod 141. There are two reinforcing grooves 143, which are respectively opened on adjacent arc rings 821. The sliding of the drive rod 141 drives the two reinforcing rods 142 to be inserted into the two reinforcing grooves respectively. Inside 143, several wedge-shaped blocks 12 on the drive ring 11 are arranged corresponding to the drive rod 141. One end of the drive rod 141 abuts against the wedge-shaped surface of the wedge-shaped block 12. When the drive ring 11 rotates, it drives the anti-detachment rod 101 to insert into the anti-detachment groove 102. At the same time, the wedge-shaped surface on the wedge-shaped block 12 drives the reinforcing rod 142 to insert into the reinforcing groove 143. A return spring 15 is provided between the reinforcing rod 142 and the main body 81. The return spring 15 drives the reinforcing rod 142 to slide towards the center of the main body 81. When the drive ring 11 rotates until the anti-detachment rod 101 is disengaged from the anti-detachment groove 102, the elastic force of the return spring 15 drives the reinforcing rod 142 to disengage from the reinforcing groove 143.

[0038] Reference Figure 2 and Figure 3 The drive ring 11 is embedded in the body part 81, and a lever 16 is fixed on the drive ring 11. The lever 16 is flush with the side wall of the body part 81. The lever 16 can easily drive the drive ring 11 to rotate. At the same time, the lever 16, which is flush with the body part 81, reduces the influence of the lever 16 on the rotation of the body part 81 and also reduces the probability of external force driving the gripper.

[0039] Reference Figure 3 and Figure 5A stabilizing component 21 is provided between adjacent arc rings 821. The stabilizing component 21 includes a stabilizing insert 211 and an anti-detachment insert 212. The stabilizing insert 211 is slidably disposed at the end of one arc ring 821, and the stabilizing insert 211 is inserted into or detached from the other arc ring 821 by sliding. The anti-detachment insert 212 is slidably disposed at the end of the other arc ring 821, and the anti-detachment insert 212 is inserted into the stabilizing insert 211 by sliding. The setting of the stabilizing component 21 can improve the stability of adjacent arc rings 821 and reduce the probability of the arc rings 821 detaching at the connection point and affecting the roll welding. Two reinforcing rods 142 on the drive rod 141 are of different lengths, one long and one short. The longer reinforcing rod 142 is inserted into one arc ring 821 to drive the stabilizing insert 211 to slide into the other arc ring 821. Inside the arc ring 821, a slope is provided on the stabilizing insert 211. The reinforcing rod 142 drives the stabilizing insert 211 to slide by abutting against the slope. The short reinforcing rod 142 is inserted into another arc ring 821, which drives the anti-detachment slider to slide into the stabilizing insert 211. Elastic elements 13 are provided between the stabilizing insert 211 and the arc ring 821, and between the anti-detachment insert 212 and the arc ring 821. The elastic elements 13 drive the stabilizing insert 211 to slide away from the other arc ring 821, and the elastic elements 13 drive the anti-detachment insert 212 to detach from the stabilizing insert 211. By using the reinforcing rod 142 in conjunction with the stabilizing component 21, the use of the reinforcing component 14 is triggered at the same time as the use of the stabilizing component 21, so as to achieve the stabilizing effect of the stabilizing component 21 without affecting normal disassembly and assembly.

[0040] Reference Figure 2 The receiving mechanism 5 includes a base plate 51 and side plates 52. The base plate 51 is fixed on the receiving platform 4. There are two side plates 52, which are slidably disposed on both sides of the base plate 51 along its length. Ball bearings 17 are embedded in both the side of the base plate 51 facing the welding roller 8 and the side of the two side plates 52 facing each other. A receiving roller 18 is rotatably disposed at the center of the base plate 51. The anti-collision beam is supported by the base plate 51 and guided by the two side plates 52, making the conveying of the anti-collision beam smoother. The ball bearings 17 can reduce the friction generated during the conveying of the anti-collision beam and reduce the frictional loss of the anti-collision beam during the conveying process. In this embodiment... Both the receiving roller 18 and the welding roller 8 are made of missile material. In this embodiment, the receiving mechanism 5 and the welding roller 8 are made of copper material. A T-shaped sliding groove 19 is provided on the base plate 51, and a T-shaped sliding block 20 is fixed on the side plate 52. The sliding block 20 is slidably set in the sliding groove 19. Bolts are bolted to the sliding block 20, and the bolts pass through the sliding block 20. Tightening the bolts makes the bolts abut against the bottom of the sliding groove 19 to fix the side plate 52. Loosening the bolts allows the side plate 52 to slide and adjust on the base plate 51. By adjusting the distance between the two side plates 52, it can be adapted to anti-collision beams of different sizes.

[0041] The implementation principle of this application embodiment is as follows: Adjust the side plate 52 according to the size of the anti-collision beam formed by bending the steel plate 1, and then install a welding part 82 of appropriate thickness on the main body 81 according to the size of the anti-collision beam groove 2. When installing the welding part 82, insert the arc ring 821 into the main body 81 in sequence and connect the ends of the arc ring 821 to form an annular welding part 82, and fit it on the outside of the main body 81. Then, move the lever 16 to make the drive ring 11 rotate. The drive ring 11 drives the anti-detachment rod 101 to insert into the anti-detachment groove 102 through the wedge block 12, and simultaneously drives the reinforcing rod 142 to insert into the reinforcing groove 143 so that the welding part 82 is reinforced and installed on the main body 81. Then, adjust the height of the welding roller 8 to a suitable position, and then send the bent steel plate 1 into the machine body 3 for roll welding to complete the welding of the anti-collision beam.
