Description

Technical Field

[0001] This invention relates to the field of welding positioning technology, and in particular to a welding positioning device for fire-fighting equipment. Background Technology

[0002] The base of a fire extinguisher is a thin-walled, frustum-shaped metal shell structure, narrower at the top and wider at the bottom. It is typically formed by rolling thin steel plates and then welding them longitudinally. In existing longitudinal seam welding processes, due to the taper of the frustum shell and its relatively poor overall rigidity, it is difficult to position the workpiece before welding. Traditional welding involves manually holding the workpiece, which can easily cause deformation, resulting in uneven seam gaps and misalignment. This not only affects the quality of the weld but also easily leads to welding deformation, causing a decrease in the roundness and dimensional accuracy of the shell.

[0003] Meanwhile, most of the existing auxiliary welding fixtures are integral fixed structures that fit tightly to the shape of the truncated cone shell. After the workpiece is welded, it is easy for it to shrink and stick to the mold due to cooling, which causes obvious problems such as inconvenience in unloading and difficulty in removing the parts. Manual assistance is often required to knock it off the mold, which not only results in high labor intensity and low work efficiency, but also easily causes the shell to be bumped and deformed, affecting the subsequent assembly accuracy with the fire extinguisher cylinder and the product qualification rate.

A positioning rod is fixedly connected to the gear. The outer wall of the positioning rod is smooth and abuts against the inner wall of the frustum-shaped cylindrical component.

[0010] Preferably, an electric actuator is fixedly connected to the other end of the universal joint A. The electric actuator is rotatably connected to the inner wall of the rotating seat. An adjusting wheel is fixedly connected to the outer end of the electric actuator. The adjusting wheel meshes with an arc-shaped rack for transmission. The bottom end of the movable frame extends through the inner wall of the rotating seat to the outside and is fixedly connected to a transmission ring. A movable ring is rotatably connected to the outer wall of the transmission ring. A sloping groove plate is fixedly connected to one side of the movable ring.

[0011] Preferably, the auxiliary positioning mechanism includes a sliding frame, which is slidably coupled to the inner wall of the flipping seat, and a contact shaft is rotatably connected to one end of the sliding frame, which is slidably in contact with the inner wall of the inclined slot plate.

[0012] Preferably, a universal joint B is rotatably connected to the sliding frame, a sponge roller is fixedly connected to the top of the universal joint B, the sponge roller is in frictional contact with the outer wall of the frustum-shaped cylindrical part, and a transmission wheel is fixedly connected to the bottom of the universal joint B, the transmission wheel is engaged with the annular rack for transmission.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a cylindrical positioning mechanism, when welding a frustum-shaped cylindrical part, multiple rotating positioning rods are used to guide the gap of the frustum-shaped cylindrical part to the welding position, which can significantly improve welding accuracy, reduce plate deformation, improve welding quality and efficiency, adapt to the complex shape of frustum-shaped plates, and greatly improve the effect and reliability of welding frustum-shaped cylindrical parts.

[0016] 2. By setting up an auxiliary positioning mechanism, before arc welding the frustum-shaped cylindrical part, the rotating seat drives the frustum-shaped cylindrical part to rotate, which in turn drives the sponge roller to rotate. The sponge roller assists in rolling the outer wall of the frustum-shaped cylindrical part, which can assist in the rotation and repositioning of the frustum-shaped cylindrical part, reduce the interference of manual operation, realize automation and precision, and ultimately improve production efficiency and product quality.

[0017] 3. By setting up a combination design of flipping seat, conical guide block and spring, the accuracy, stability and safety of receiving frustum-shaped cylindrical parts can be effectively improved. The automated operation not only improves production efficiency and reduces manual intervention, but also protects the welded plates and avoids damage and impact. The buffering effect of the spring reduces the impact during the falling process and ensures that the plates make stable contact, which further improves the receiving quality and makes the receiving process of frustum-shaped cylindrical parts more efficient.

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1-8 The fire-fighting equipment welding and positioning device shown includes a processing base 1, a welding mechanism 2 mounted on the processing base 1, two fixed frames 3 fixedly connected to the processing base 1, a tilting base 4 rotatably connected between the two fixed frames 3, a rotating base 5 rotatably connected to the tilting base 4, a cylindrical part positioning mechanism 6 rotatably connected inside the rotating base 5, an auxiliary positioning mechanism 7 slidably fitted on one side of the tilting base 4, a base 8 fixedly connected below the processing base 1, and a material receiving seat 9 slidably fitted on the base 8. The welding mechanism 2 adopts automatic and semi-automatic arc welding methods, integrating a welding power source, welding torch, and wire feeding assembly, which will not be described in detail.

[0029] like Figure 3 As shown, one end of one of the fixed frames 3 is fixedly connected to a motor A301, the output end of the motor A301 is fixedly connected to the flipping seat 4, and two arc-shaped racks 302 are fixedly connected to the fixed frame 3.

[0030] like Figure 4 As shown, a motor B401 is fixedly connected to one end of the flip base 4, and the output end of the motor B401 is fixedly connected to the rotating base 5.

[0031] like Figure 5As shown, a frustum-shaped cylindrical component 501 is placed on the rotating seat 5, and an annular rack 502 is fixedly connected to the outside of the rotating seat 5. The rotating seat 5 is driven to rotate one revolution by the motor B401, so that the rotating seat 5 can drive the frustum-shaped cylindrical component 501 to rotate. At this time, the annular rack 502 on the rotating seat 5 will drive the transmission wheel 705 to rotate, so that the transmission wheel 705 drives the sponge roller 704 connected to the universal joint B703 to rotate.

[0032] like Figure 6 As shown, the cylindrical positioning mechanism 6 includes a universal joint A601. A reciprocating screw 602 is fixedly connected to one end of the universal joint A601. The reciprocating screw 602 is rotatably connected to the inner wall of the rotating seat 5. A movable frame 603 is slidably fitted on the outer wall of the reciprocating screw 602. Multiple transmission racks 604 are fixedly connected to the movable frame 603. A gear 605 is meshed on one side of the transmission racks 604. The gear 605 is rotatably connected to the inner wall of the rotating seat 5. A positioning rod 606 is fixedly connected to the gear 605. The outer wall of the positioning rod 606 is smooth. The outer wall of the positioning rod 606 abuts against the inner wall of the frustum-shaped cylindrical part 501. The smooth design of the outer wall of the positioning rod 606 ensures that it does not interfere with the automatic rotation of the frustum-shaped cylindrical part 501, so as to facilitate the adjustment of the position of the gap to be welded.

[0033] The other end of the universal joint A601 is fixedly connected to an electric actuator 607. The electric actuator 607 is rotatably connected to the inner wall of the rotating seat 5. The outer end of the electric actuator 607 is fixedly connected to an adjusting wheel 608. The adjusting wheel 608 is meshed with the arc-shaped rack 302 for transmission. The bottom end of the movable frame 603 extends through the inner wall of the rotating seat 5 to the outside and is fixedly connected to a transmission ring 609. The outer wall of the transmission ring 609 is rotatably connected to a moving ring 610. A sloping groove plate 611 is fixedly connected to one side of the moving ring 610. Under the action of the arc-shaped rack 302, the meshing adjusting wheel 608 will rotate, causing the adjusting wheel 608 to drive the universal joint A601 connected to the electric push rod 607 to rotate, so that the universal joint A601 can drive the connected reciprocating screw 602 to rotate, so that the reciprocating screw 602 can drive the movable frame 603 to move. At this time, the movable frame 603 will drive multiple transmission racks 604 to move, and the transmission racks 604 will drive the gear 605 to rotate, so that the gear 605 will drive the connected positioning rod 606 to rotate.

[0034] By setting up the cylindrical part positioning mechanism 6, when welding the frustum-shaped cylindrical part 501 is required, multiple rotating positioning rods 606 are used to stably guide and position the frustum-shaped cylindrical part 501, which can significantly improve welding accuracy, reduce plate deformation, adapt to the complex shape of the frustum-shaped plate, and greatly improve the welding effect and reliability of the frustum-shaped cylindrical part 501.

[0035] like Figure 7As shown, the auxiliary positioning mechanism 7 includes a sliding frame 701, which is slidably engaged with the inner wall of the flipping seat 4. One end of the sliding frame 701 is rotatably connected to a contact shaft 702, which is slidably in contact with the inner wall of the inclined groove plate 611.

[0036] A universal joint B703 is rotatably connected to the sliding frame 701. A sponge roller 704 is fixedly connected to the top of the universal joint B703, and the sponge roller 704 is in frictional contact with the outer wall of the frustum-shaped cylindrical component 501. A transmission wheel 705 is fixedly connected to the bottom of the universal joint B703, and the transmission wheel 705 meshes with the ring rack 502 for transmission. When the movable frame 603 moves, it drives the connected transmission ring 609 to move. At this time, the transmission ring 609 drives the moving ring 610 to move, and then the moving ring 610 drives the connected inclined plate 611 to move, so that the inclined groove on the inclined plate 611 can drive the sliding frame 701 connected to the contact shaft 702 to move, so that the sponge roller 704 on the sliding frame 701 contacts the outer wall of the frustum-shaped cylindrical component 501.

[0037] like Figure 8 As shown, a conical guide block 901 is fixedly connected to the receiving base 9, and a slide 902 is provided below the receiving base 9. Multiple springs 903 are fixedly connected to the slide 902, and the other end of the springs 903 is fixedly connected to the receiving base 9. Multiple guide rods 905 are fixedly connected to the bottom end of the receiving base 9. The guide rods 905 and the slide 902 are slidably engaged. Multiple track wheels 904 are rotatably connected to the bottom end of the slide 902. The track wheels 904 are slidably contacted with the track 801 opened on the base 8.

[0038] Working principle: When welding is required on the frustum-shaped cylindrical part 501, the small end of the opening of the frustum-shaped cylindrical part 501 is first inserted into the outside of the cylindrical part positioning mechanism 6.

[0039] Then, the motor A301 drives the tilting seat 4 to rotate, so that the frustum-shaped cylindrical part 501 is in a vertical state. At this time, under the action of the arc rack 302, the meshing adjusting wheel 608 will rotate, which will drive the universal joint A601 connected to the electric push rod 607 to rotate, so that the universal joint A601 can drive the connected reciprocating screw 602 to rotate, which will drive the movable frame 603 to move. At this time, the movable frame 603 will drive multiple transmission racks 604 to move, which will drive the gear 605 to rotate, which will drive the connected positioning rod 606 to rotate and press against the inner wall of the frustum-shaped cylindrical part 501 to achieve positioning of the frustum-shaped cylindrical part 501.

[0040] At the same time, when the movable frame 603 moves, it will drive the connected transmission ring 609 to move. At this time, the transmission ring 609 will drive the moving ring 610 to move, and then the moving ring 610 will drive the connected inclined plate 611 to move, so that the inclined groove on the inclined plate 611 can drive the sliding frame 701 connected to the contact shaft 702 to move, so that the sponge roller 704 on the sliding frame 701 contacts the outer wall of the frustum-shaped cylinder 501.

[0041] Before welding the outer wall of the frustum-shaped cylindrical component 501, the electric actuator 607 drives the adjusting wheel 608 to retract, and then the motor B401 drives the connected rotating seat 5 to rotate one revolution, so that the rotating seat 5 can drive the frustum-shaped cylindrical component 501 to rotate. At this time, the annular rack 502 on the rotating seat 5 will drive the transmission wheel 705 to rotate, so that the transmission wheel 705 drives the sponge roller 704 connected to the universal joint B703 to rotate, so that the sponge roller 704 can assist in positioning the outer wall of the frustum-shaped cylindrical component 501, so that the frustum-shaped cylindrical component 501 is rotated and adjusted to align the gap with the welding mechanism 2.

[0042] Then, the welding mechanism 2 is used to perform gap welding on the frustum-shaped cylindrical part 501. After welding is completed, the electric push rod 607 drives the adjusting wheel 608 to move out and reset. At this time, when the motor A301 drives the flipping seat 4 to rotate, the frustum-shaped cylindrical part 501 will rotate to the lower side. At this time, the adjusting wheel 608 will mesh with the arc-shaped rack 302 on the lower side, which will drive the positioning rod 606 to rotate and reset. At this time, the frustum-shaped cylindrical part 501 is unrestricted and will fall automatically.

[0043] Then, the falling frustum-shaped cylindrical component 501 is guided by the conical guide block 901 on the receiving seat 9, so that the frustum-shaped cylindrical component 501 falls onto the receiving seat 9. When a certain amount of frustum-shaped cylindrical components 501 are stacked on the receiving seat 9, the slide 902 can be pulled out to facilitate the removal of the welded frustum-shaped cylindrical component 501.
