Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe manufacturing technology, and in particular to a welding support device for the production of automotive exhaust corrugated pipes. Background Technology

[0002] The main functions of using corrugated pipes in automotive exhaust systems include vibration and noise reduction, ease of installation, and extending the lifespan of the exhaust muffler system. The corrugated pipe is installed in the exhaust pipe between the engine exhaust manifold and the muffler, making the entire exhaust system flexibly connected, thus achieving the functions of vibration and noise reduction, ease of installation, and extending the lifespan of the exhaust muffler system.

[0003] To facilitate the installation of automotive exhaust bellows, flanges need to be welded and fixed at both ends of the bellows. To ensure that the mounting holes of the flanges at both ends correspond and facilitate connection with the flanges at the ends of the pipe, the flanges at the ends of the bellows need to be effectively positioned. During the welding process, the coaxiality of the flanges and the bellows needs to be ensured. Therefore, during the welding process, while ensuring effective clamping, the inside of the bellows needs to be supported, and the supported bellows needs to be coaxial with the flanges. Existing clamping equipment supports the bottom of the bellows, which not only results in poor coaxiality but also easily causes the bellows to sag at both ends, thus affecting the welding dimensions and welding quality. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a welding support device for the production of automotive exhaust bellows.

[0005] This utility model is achieved through the following technical solution:

[0006] A welding support device for producing automotive exhaust bellows includes a rotating shaft, a backing plate, a bellows, a flange, a clamping plate, a clamping knob, an inner support mechanism, a control knob, a control sleeve, and a limiting pin. The backing plate is fixedly mounted on the surface of the rotating shaft, the inner support mechanism is fixedly mounted on the surface of the rotating shaft, the bellows is sleeved outside the inner support mechanism, the flange is located at both ends of the bellows, the clamping plate is sleeved on the surface of the rotating shaft, the clamping knob and the control knob are threadedly connected to one end of the rotating shaft, the control sleeve is fixedly mounted inside the control knob, and the limiting pin is fixedly mounted inside the backing plate and the clamping plate.

[0007] In a preferred embodiment of this utility model, the inner support mechanism includes a mounting base, a retaining shaft, a sliding shaft, a cross brace, an inner support bar, and a slider. The mounting base is fixed to the surface of the rotating shaft. The retaining shaft and the sliding shaft are movably connected to the mounting base. The bottom of the cross brace is movably connected to the retaining shaft and the sliding shaft, respectively. The inner support bar is movably connected to the top of the cross brace. The slider is movably connected to the end of the sliding shaft.

[0008] The internal support mechanism mainly supports the inside of the bellows. By controlling the knob, pressure is applied to the control sleeve, causing the slider to move under pressure and lift the cross bracing, so that the internal support bar contacts the inside of the control sleeve, achieving an effective support effect.

[0009] In a preferred embodiment of this utility model, a groove is provided at the bottom of the slider, and the bottom of the slider is engaged with the top of the mounting base;

[0010] The slider is secured at the top of the mounting base, ensuring both the pressure applied by the control sleeve and the control effect on the sliding shaft.

[0011] In a preferred embodiment of the present invention, the mounting base is provided with a sliding hole that cooperates with the sliding shaft, the bottom of the inner support bar is provided with a connecting piece that cooperates with the cross support rod, and the top of the inner support bar contacts the inner side of the corrugated pipe.

[0012] In a preferred embodiment of this utility model, the limiting pin is fastened in the mounting hole on the surface of the flange, and the flange and the bellows are clamped between the backing plate and the clamping plate.

[0013] In a preferred embodiment of the present invention, one end of the rotating shaft is threaded, a limit strip is provided inside the clamping plate, and a guide groove that cooperates with the rotating shaft is provided on the surface of the rotating shaft.

[0014] The guide groove on the rotating shaft surface ensures the installation angle of the clamping plate, thereby ensuring that the installation positions of the backing plate and the inner limit pins of the clamping plate correspond, and thus ensuring that the welding positions of the flanges at both ends of the bellows correspond.

[0015] The beneficial effects of this utility model are:

[0016] This welding support equipment for producing automotive exhaust bellows clamps and fixes the flanges to be welded at both ends of the bellows, effectively ensuring that the mounting holes of the flanges at both ends correspond, and provides effective support inside the bellows, increasing the support area of ​​the inner wall of the bellows, ensuring the straightness of the bellows, and ensuring the coaxiality of the bellows and the flanges at both ends, thereby improving product quality and ensuring welding effect.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0023] like Figure 1-4 The welding support equipment for producing automotive exhaust bellows shown includes a rotating shaft 1, a backing plate 2, a bellows 3, a flange 4, a clamping plate 5, a clamping knob 6, an inner support mechanism 7, a control knob 8, a control sleeve 9, and a limiting pin 10. The backing plate 2 is fixedly mounted on the surface of the rotating shaft 1, the inner support mechanism 7 is fixedly mounted on the surface of the rotating shaft 1, the bellows 3 is sleeved on the outside of the inner support mechanism 7, the flange 4 is located at both ends of the bellows 3, the clamping plate 5 is sleeved on the surface of the rotating shaft 1, the clamping knob 6 and the control knob 8 are threadedly connected to one end of the rotating shaft 1, the control sleeve 9 is fixedly mounted inside the control knob 8, and the limiting pin 10 is fixedly mounted inside the backing plate 2 and the clamping plate 5.

[0024] Specifically, the inner support mechanism 7 includes a mounting base 71, a retaining shaft 72, a sliding shaft 73, a cross brace 74, an inner support bar 75, and a slider 76. The mounting base 71 is fixed to the surface of the rotating shaft 1. The retaining shaft 72 and the sliding shaft 73 are movably connected to the mounting base 71. The bottom of the cross brace 74 is movably connected to the retaining shaft 72 and the sliding shaft 73, respectively. The inner support bar 75 is movably connected to the top of the cross brace 74. The slider 76 is movably connected to the end of the sliding shaft 73. A groove is provided at the bottom of the slider 76. The part is mounted on the top of the mounting base 71. The mounting base 71 has a sliding hole that mates with the sliding shaft 73. The bottom of the inner support bar 75 has a connecting piece that mates with the cross support rod 74. The top of the inner support bar 75 contacts the inner side of the bellows 3. The limiting pin 10 is mounted in the mounting hole on the surface of the flange 4. The flange 4 and the bellows 3 are clamped between the backing plate 2 and the clamping plate 5. One end of the rotating shaft 1 has a thread. The clamping plate 5 has a limiting strip inside. The surface of the rotating shaft 1 has a guide groove that mates with it.

[0025] In this embodiment, firstly, a flange 4 is fitted onto the surface of the rotating shaft 1, so that its outer side is in contact with the backing plate 2. The limiting pin 10 is locked in the mounting hole on the surface of the flange 4. Then, the bellows 3 is fitted onto the outside of the inner support mechanism 7, and the control knob 8 is rotated. The control knob 8 moves inward according to the thread on the surface of the rotating shaft 1, thereby causing the control sleeve 9 to press the slider 76. The control sleeve 9 ensures that all sliders 76 of the inner support mechanism 7 are pressed synchronously, thereby causing the slider 76 to slide on the top of the mounting base 71, thereby causing the sliding shaft 73 to slide in the groove, and then the cross support rod 74 is raised, pushing the inner support bar 75 against the inner wall of the bellows 3, thereby achieving the effect of supporting the bellows 3.

[0026] Furthermore, after another flange 4 is fitted onto the surface of the rotating shaft 1, the clamping plate 5 is fitted onto the surface of the rotating shaft 1. The retaining strip on the inner side of the clamping plate 5 is engaged in the guide groove on the surface of the rotating shaft 1, thereby ensuring the positioning of the clamping plate 5. After the flange 4 is engaged on the surface of the limiting nail 10 on the inner side of the clamping plate 5, it can correspond to the flange 4 on the inner side of the backing plate 2. Then, tighten the clamping knob 6 to apply pressure to the outer side of the clamping plate 5, thereby protecting the flange 4 and effectively clamping it at both ends of the bellows 3, which facilitates the welding work. During the welding process, the motor drives the rotating shaft 1 to rotate slowly, thereby automatically switching the welding position and ensuring the welding quality.

[0027] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
