Description

Technical Field

[0001] This utility model relates to the field of muffler welding and processing technology, and in particular to a muffler clamping auxiliary welding device. Background Technology

[0002] The muffler is one of the key components of a motorcycle. It relies on structures such as abrupt changes in the cross-section of the pipe or the side resonance cavity to change the path of the exhaust airflow or absorb sound wave energy to reduce the noise generated by the engine and exhaust system, thereby reducing noise pollution to the surrounding environment and improving riding comfort.

[0003] Once the muffler is manufactured, such as Figure 1 As shown, to prevent cracks and holes from appearing in the muffler due to rust, impact, or aging during use, which could lead to increased exhaust noise or air leakage, a protective layer is often wrapped around the surface of the muffler to isolate it from external corrosion and extend its lifespan. During assembly, the protective layer is typically bent and welded into a specified cylindrical structure, and then the muffler is installed into this cylindrical structure. Because the inner diameter of the protective layer is almost the same as the outer diameter of the muffler, assembly is relatively difficult and inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a muffler clamping auxiliary welding device, which solves the problem of difficulty in assembling the muffler and protective layer in existing technologies.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] A muffler clamping auxiliary welding device for installing a protective layer onto the muffler body, comprising:

[0007] Base plate;

[0008] Fixed plate, fixedly installed on the base plate;

[0009] A movable plate, slidably mounted on the base plate, corresponds to the fixed plate to form a mounting cavity for installing the muffler body and protective layer; and

[0010] The driving component, located on the base plate and connected to the movable plate, is used to bring the movable plate closer to the fixed plate so that the protective layer is subjected to force and wraps around the muffler body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In contrast to traditional processes that require pre-bending and welding the protective layer into a cylindrical shape before forcibly fitting it into the muffler, this solution pre-bends the protective layer to further wrap around the muffler body. A driving component then pushes a moving plate to compress the protective layer, ensuring that the muffler body and the protective layer are tightly positioned within the mounting cavity formed by the fixed and moving plates. Finally, a welding machine is used to weld the two ends of the protective layer, quickly and completely wrapping the protective layer around the muffler body and effectively improving the assembly efficiency.

[0014] The driver is located on the base plate;

[0016] Preferably, the top of the fixing plate is provided with a threaded seat, and the threaded seat is threadedly connected to a screw, the end of which penetrates into the mounting cavity and abuts against the protective layer.

[0017] Preferably, the two sides of the fixing plate are bent outward to form the mounting part, and the base plate is bolted to a pressing plate, which presses against the mounting part.

[0018] Preferably, the base plate is bolted to a support plate, which abuts against the fixed plate.

[0019] Preferably, the support plate is provided with reinforcing ribs.

[0020] Preferably, the base plate is provided with a slide rail, and the bottom of the movable plate is provided with a slider, which slides along the slide rail.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] This utility model embodiment proposes a muffler clamping auxiliary welding device for installing the protective layer 2 onto the muffler body 1, comprising:

[0028] Base plate 10;

[0029] Fixed plate 3 is fixedly installed on base plate 10;

[0030] The movable plate 4 is slidably disposed on the base plate 10 and corresponds to the fixed plate 3 to form a mounting cavity for mounting the muffler body 1 and the protective layer 2; and

[0031] A driving component is provided on the base plate 10 and connected to the movable plate 4. It is used to bring the movable plate 4 close to the fixed plate 3 so that the protective layer 2 is subjected to force and wrapped around the muffler body 1.

[0032] In the embodiments of this utility model, such as Figure 1 As shown, after the muffler body 1 and the protective layer 2 are assembled, the two ends of the protective layer 2 are just right. Finally, the two ends are fixedly connected by welding. The welding method can be manual welding or robotic arm welding.

[0033] In the initial assembly stage, the fixed plate 3 and the movable plate 4 are initially separated, and the distance between them is greater than the outer diameter of the muffler body 1. The protective layer 2 is initially a flat plate structure, mainly made of flexible metal materials such as stainless steel or aluminum alloy. Before using the protective layer 2, it can be pre-bent to the outer arc shape of the muffler body 1, so that the protective layer 2 wraps around the muffler body 1 and fits it as closely as possible. However, because the protective layer 2 has a certain degree of elasticity, even if the protective layer 2 is included on the muffler body 1 as much as possible, there will still be a certain height difference or gap between the two ends of the protective layer 2. Therefore, the structure of both is first placed in the arc groove of the fixed plate 3, with the inner arc of the fixed plate 3 corresponding to the inner arc of the muffler body 1. The driving component moves the movable plate 4 closer to the fixed plate 3, so that the movable plate 4 presses the protective layer 2 and the muffler body 1, thereby making the end of the protective layer 2 close to the movable plate 4 gradually move closer to the other end. Finally, welding is performed.

[0034] In some other embodiments, such as Figure 2As shown, the inner arc of the movable plate 4 near its top first contacts the end of the protective layer 2 wrapped around the muffler body 1. During the movement of the movable plate 4, a circumferential force is applied to the protective layer 2 through the contact of the movable plate 4, allowing the protective layer 2 to fit more tightly against the outside of the muffler body 1, preventing holes between the protective layer 2 and the muffler body 1. The aforementioned driving component can be adjusted by telescopic means, such as hydraulic, electric, or pneumatic rods, or by threaded transmission, such as a lead screw.

[0035] Based on the above scheme, in order to ensure the transmission stability of the moving plate 4, such as Figure 2 As shown, the driving component includes:

[0036] Driver 9 is located on base plate 10;

[0037] The transmission screw 901 is located at the output end of the driver 9, and the moving plate 4 is provided with a connecting block 401. The transmission screw 901 is threadedly connected to the connecting block 401.

[0038] Specifically, when adjusting the movable plate 4, the driver 9 is activated, causing the output shaft of the driver 9 to rotate the transmission screw 901, thereby causing the connecting block 401 to move along the axis of the transmission screw 901. In turn, the connecting block 401 drives the movable plate 4 to move closer to or away from the fixed plate 3, thus implementing the clamping installation of the protective layer 2.

[0039] Before clamping installation, it is necessary to ensure that the end of the protective layer 2, which is located at the position of the fixing plate 3, is fixed. Therefore, if Figure 2 As shown, the top of the fixing plate 3 is provided with a threaded seat 301, and a screw 302 is threadedly connected to the threaded seat 301. The end of the screw 302 penetrates into the mounting cavity and abuts against the protective layer 2. When the muffler body 1 carrying the protective layer 2 enters the arc-shaped groove of the fixing plate 3, the screw 302 is rotated, causing it to descend on the threaded seat 301, thereby abutting the end of the screw 302 against the protective layer 2. This ensures that the position of this end of the protective layer 2 will not move, that is, it will not be displaced by the clamping of the moving plate 4, thus ensuring the accuracy of the connection between the two ends of the protective layer 2. Specifically, in some embodiments, such as Figure 2 As shown in the dotted line at the bottom of the threaded seat 301, in order to prevent the screw 302 from directly pressing the protective layer 2 and causing it to deform locally, a pressing plate is slidably connected in the fixed plate 3. The screw 302 is rotatably connected to the pressing plate. The movement of the screw 302 causes the pressing plate to press against the protective layer 2, which not only ensures stability but also prevents point-type local deformation.

[0040] Specifically, such as Figure 1As shown, the two sides of the fixing plate 3 are bent outward to form the mounting part 303. The base plate 10 is bolted to a pressing plate 5, which presses against the mounting part 303. By pressing the pressing plate 5 into the mounting part 303, the fixing plate 3 can be quickly fixed to the base plate 10. The fixing plate 3 can be quickly replaced for different welding processes of the muffler body 1. At the same time, the base plate 10 is bolted to a support plate 6, which abuts against the fixing plate 3. By abutting against the axis of the transmission screw 901, the stability of the fixing plate 3 can be enhanced, preventing it from moving during clamping. Moreover, the support plate 6 is provided with reinforcing ribs 601 and has an L-shaped structure, which can ensure the structural stability of the support plate 6 and prevent structural deformation.

[0041] Specifically, such as Figure 1 As shown, the base plate 10 is provided with a slide rail 7, and the bottom of the movable plate 4 is provided with a slider 701. The slider 701 is slidably mounted on the slide rail 7. With the cooperation of the slide rail 7 and the slider 701, the movement path of the movable plate 4 can be restricted, which not only facilitates the transmission of the transmission screw 901, but also reduces the pressure on the transmission screw 901. At the same time, the fixed plate 3 is fixedly provided with a limiting rod 8, and the movable plate 4 is slidably mounted on the limiting rod 8. The limiting rod 8 further restricts the movement path of the movable plate 4. When the movable plate 4 is driven by the driving component, the slider 701 is prevented from being subjected to an upward force on the slide rail 7, ensuring the cooperation relationship between the components.

[0042] In this solution, the traditional distributed assembly (pre-bending protective layer → sleeve → welding) is optimized to be completed simultaneously, allowing the protective layer 2 to be initially in a semi-formed state, thereby facilitating the assembly between the muffler body 1 and the protective layer 2.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
