[0002] The motorcycle exhaust pipe is an important part of the motorcycle engine system, which connects the engine cylinder and the external environment of the vehicle body. When processing and producing motorcycles, motorcycle exhaust pipe connection welding is required, which refers to connecting different parts of the exhaust pipe together by welding.

[0003] When welding a motorcycle exhaust pipe, the existing welding method is to place both ends of the exhaust pipe on a workbench and align them by hand, and then connect different parts of the exhaust pipe by welding methods such as electric welding, argon arc welding or gas shielded welding.

[0004] Since the wall of motorcycle exhaust pipe is usually thin and the area is large, the heat generated during welding can easily cause the pipe to overheat locally and deform, so the workers need to accurately control the welding points during welding. At the same time, this method requires a long time to align the two parts of the exhaust pipe, which will cause the workers to pay attention to the docking of the two exhaust pipes while welding, increasing the welding burden of the workers and affecting the subsequent welding effect.

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0027] The following describes the motorcycle parts production welding and fixing device according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 4 As shown, the motorcycle parts production welding and fixing device of the embodiment of the utility model may include a base plate 1, a plurality of pillars 2, a support plate 3, two sliding mechanisms 4, two supporting mechanisms 5 and two conveying mechanisms 6.

[0029] Among them, a plurality of pillars 2 are installed on the base plate 1 , and the support plate 3 is installed on the pillars 2 .

[0030] It can be understood that the pillars 2 are provided mainly for supporting the support plate 3 .

[0031] The support plate 3 is provided with a slot, and two sliding mechanisms 4 are mounted on the support plate 3 . The sliding mechanisms 4 include a housing 41 and a slide bar 42 .

[0032] There are tooth grooves on both sides of the bottom of the shell 41 , and two slide bars 42 are installed on the inner wall of the shell 41 . The sliding mechanism 4 is slidably connected with the slide groove 31 on the support plate 3 through the slide bars 42 .

[0033] It should be noted that the width of the support plate 3 matches the width of the housing 41, and the positions of the two slide bars 42 and the slide grooves 31 match each other, so that the housing 41 can slide freely on the surface of the support plate 3.

[0034] The two support mechanisms 5 are relatively mounted on the two sliding mechanisms 4. It should be noted that the motorcycle exhaust pipe can be fixed by the provided support mechanism 5, so as to ensure that the motorcycle exhaust pipe remains aligned during welding.

[0035] The transmission mechanism 6 is installed at the bottom of the housing 41 and is engaged and connected with the housing 41 .

[0036] It can be understood that the transmission mechanism 6 can move the housing 41 by engaging with two sides of the housing 41 .

[0037] Specifically, when it is necessary to weld the two parts of the motorcycle exhaust pipe, the two ends to be welded need to be placed on the two supporting mechanisms 5 respectively. At the same time, the pressure rod 525 is pushed upward by hand. At this time, the pressure rod 525 will drive the expansion clamp 522 to rotate toward the cross bar 521 and compress the spring 523. At this time, one end of the exhaust pipe is placed on the expansion clamp 522, and the two pressure rods 525 are slowly released. The spring 523 rebounds, so that the expansion clamp 522 fixes the inner wall of the exhaust pipe. The installation steps of the other part of the exhaust pipe are the same, thereby achieving the clamping and fixation of the motorcycle exhaust pipe.

[0038] Afterwards, the rotating motors 62 on both sides are controlled to rotate, and the rotating motors 62 will drive the first gear 61 to rotate. When the first gear 61 rotates, the second gear 68 will be driven to rotate through the linkage rod 65. The first gear 61 and the second gear 68 are respectively engaged with the two sides of the shell 41, thereby realizing the movement of the shell 41 on the surface of the support plate 3, so that the exhaust pipe components on both sides are close, thereby ensuring the stability of the motorcycle exhaust pipe during welding, reducing the burden on the hands of the staff, and improving the subsequent welding quality and effect.

[0039] Optionally, in an embodiment of the utility model, a rotation support mechanism 7 is provided on the shell 41 , and the rotation support mechanism 7 includes a thread groove 71 and a screw rod 72 , wherein the thread groove 71 is provided on the surface of the shell 41 , and the screw rod 72 and the thread groove 71 are threadedly connected.

[0040] Meanwhile, a pad support component can be installed on the screw rod 72. When the exhaust pipe is installed, the rotation of the screw rod 72 can be controlled to adjust the height of the extension of the screw rod 72 to support one side of the exhaust pipe, thereby enhancing the stability of the exhaust pipe.

[0041] In one embodiment of the present invention, Figure 3 As shown, the transmission mechanism 6 may include a first gear 61 , a rotating motor 62 , a support plate 63 , a first mounting column 64 , a linkage rod 65 , a bearing ring 66 , a second mounting column 67 and a second gear 68 .

[0042] The first gear 61 and the second gear 68 are connected via a linkage rod 65 , and the first gear 61 and the second gear 68 are meshedly connected with two sides of the bottom of the housing 41 , respectively.

[0043] It is understandable that the linkage rod 65 can link the rotation state of the first gear 61 and the second gear 68 to keep the two gears in a synchronous rotation state, thereby being able to simultaneously perform meshing movement on both sides of the housing 41 .

[0044] The bearing ring 66 is installed in the middle of the linkage rod 65 .

[0045] It should be noted that in order to maintain the balance between the two gears, the connection between the two gears needs to be supported. The bearing ring 66 provided does not affect the rotation of the linkage rod 65. At the same time, supporting the bearing ring 66 can achieve support for one side of the second gear 68, thereby enabling the first gear 61 and the second gear 68 to remain on the same horizontal line.

[0046] The output shaft of the rotating motor 62 is connected to the center of the first gear 61 , and the supporting plate 63 is installed at the bottom of the rotating motor 62 .

[0047] It should be noted that, in order to enable the two sliding mechanisms 4 to move relatively, when the two rotating motors 62 are installed, the output shafts of the two rotating motors 62 need to rotate in opposite directions.

[0048] The first mounting column 64 is mounted on the bottom of the support plate 63 , and the second mounting column 67 is mounted on the bottom of the bearing ring 66 .

[0049] It can be understood that the rotating motor 62 can be supported by the first mounting column 64, and the linkage shaft can be supported by the second mounting column 67.

[0050] In one embodiment of the present invention, Figure 4 As shown, the supporting mechanism 5 may include a first support rod 51 , a clamping assembly 52 and a second support rod 53 .

[0051] The first support rod 51 is in an "L" shape.

[0052] As a possible situation, a push rod motor may be provided at the bottom of the first support rod 51 to adjust the height of the first support rod 51 .

[0053] The applicant's consideration for this situation is that the connecting parts on both sides of the motorcycle exhaust pipe are not straight-cylindrical, so there may be a height difference in the spliced ​​parts of the exhaust pipe after clamping it. At this time, the height of the first support rod 51 can be controlled by the push rod motor so that the two parts to be welded are at the same height.

[0054] The clamping assembly 52 is installed on one side of the first support rod 51 , and the second support rod 53 is installed on the other side of the clamping assembly 52 .

[0055] It can be understood that the second support rod 53 is used to support the exhaust pipe to prevent the exhaust pipe from falling due to an incomplete clamping step.

[0056] In one embodiment of the present invention, Figure 4 As shown, the clamping assembly 52 may include a cross bar 521 , an expansion clamp 522 , a spring 523 , a rotation shaft 524 and a pressure rod 525 .

[0057] Among them, the cross bar 521 is installed between the first support bar 51 and the second support bar 53, multiple expansion clamps 522 are rotatably connected to the cross bar 521 through the rotating shaft 524, the spring 523 is installed between the expansion clamp 522 and the cross bar 521, and the pressure rod 525 is installed on one side of the expansion clamp 522.

[0058] It should be noted that the component uses the elastic force of the spring 523 to open the expansion clip 522, thereby supporting the inner wall of the exhaust pipe. When designing the expansion clip 522, an arc can be set on the surface of the expansion clip 522 to fit the shape of the exhaust pipe, and a buffer sheet (such as a sponge sheet, etc.) can be installed on the surface of the expansion clip 522 to reduce the elastic force of the spring 523.

[0059] At the same time, when the expansion clamp 522 is expanded outward by the spring 523, the pressure rods 525 on both sides of the expansion clamp 522 are close to each other, so the distance between the pressure rods 525 will be smaller than the diameter of the exhaust pipe, which will not affect the clamping of the exhaust pipe.

[0060] In summary, the motorcycle parts production welding and fixing device of the embodiment of the utility model can clamp the two ends of the motorcycle exhaust pipe, ensure the stability of the motorcycle exhaust pipe during welding, reduce the burden on the hands of the workers, and improve the subsequent welding quality and effect.
