Description

Technical fields:

[0001] This utility model belongs to the technical field of motorcycle manufacturing, and specifically refers to a welding equipment for assembling and splicing motorcycle frames. Background technology:

[0002] The motorcycle frame can be considered the "skeleton" of the entire vehicle. It not only supports core components such as the engine, steering mechanism, and rear shock absorber, but also provides precise mounting positions for components such as the fuel tank, battery, and seat.

[0003] In the manufacturing process of the chassis, the chassis is first disassembled into several basic units (such as the head tube module, engine support module, rear swingarm mounting module, etc.). The tubes and plates inside each module are precisely welded to form an independent functional unit. Then, each module is precisely positioned using tooling fixtures, and the overall frame is then assembled and welded together.

[0004] For automated welding equipment, welding sparks are generated during the welding process. When these sparks fall onto the frame unit tubes, they can easily form irregular protrusions on the surface of the frame tubes, affecting the welding quality and requiring improvement. Summary of the Invention:

[0005] The purpose of this invention is to provide a welding device for assembling and splicing motorcycle frames, so as to solve the technical problems mentioned in the background art.

[0006] This utility model is implemented as follows:

[0007] A welding device for assembling and splicing motorcycle frames includes a welding robot and a welding frame. The welding frame is provided with a first clamping member and a second clamping member, which are respectively used to clamp two unit tubes. A welding station is provided between the first clamping member and the second clamping member, and the welding joints of the two end unit tubes are located at the welding station. An integrated fan is provided on the welding frame, and the air outlet of the integrated fan is away from the welding station. The integrated fan is used to blow away the sparks falling on the unit tubes.

[0008] By adopting the above technical solution, the two unit tubes that need to be connected are clamped on the first clamping member and the second clamping member respectively during the welding process. The ends of the two unit tubes are attached together, and the welding robot welds the attached part of the unit tubes. During the welding process, the integrated fan blows the sparks falling on the unit tubes away from the unit tubes, reducing the formation of protrusions on the unit tubes by the sparks, which helps to improve the welding quality.

[0009] Preferably, the angle between the axis of the integrated fan outlet and the distribution direction of the first and second clamping members is 0°-15°.

[0010] By adopting the above technical solution, the airflow can be blown a greater distance.

[0011] Preferably, the integrated fan includes a fan body disposed on the welding clamp, an air inlet pipe disposed on the fan body, and an air outlet pipe disposed on the fan body. The end of the air outlet pipe away from the fan body is opposite to the welding station, and the end of the air inlet pipe away from the fan body is facing the welding station.

[0012] By adopting the above technical solution, with the air inlet pipe facing the welding station and the air outlet pipe facing away from the welding station, the integrated fan can collect some of the sparks that fly during welding through the air inlet pipe during operation.

[0013] Preferably, the air inlet pipe includes a main pipe disposed on the fan body, a first branch pipe disposed on the main pipe, and a second branch pipe disposed on the main pipe, wherein the ends of the first branch pipe and the second branch pipe away from the fan body are parallel to the distribution direction of the first clamping member and the second clamping member.

[0014] By adopting the above technical solution, the blower can simultaneously blow the falling sparks away from both unit tubes when it is working.

[0015] Preferably, a first support frame and a second support frame are slidably connected on the welding frame. The first support frame is used to support the first branch pipe, and the second support frame is used to support the second branch pipe. The first support frame and the second support frame move towards each other and approach the welding station, so that the ends of the first branch pipe and the second branch pipe away from the fan body are located above the unit pipe. The first support frame and the second support frame move away from each other and move away, so that the first branch pipe and the second branch pipe are removed from above the unit pipe.

[0016] By adopting the above technical solution, during the welding process, the first support frame and the second support frame drive the first branch pipe and the second branch pipe to move to the welding station for measurement. During the welding process, the main body of the fan works to blow away the sparks that fall after splashing away from the unit pipe. After the welding is completed, the first support frame and the second support frame are moved away from each other, which drives the positioning first branch pipe and the second branch pipe to move away from the top of the unit pipe, making it easier to remove the unit pipe.

[0017] Preferably, the air inlet pipe is provided with a filter chamber, which is used to prevent welding slag from entering the fan body.

[0018] By adopting the above technical solution, sparks can be prevented from entering through the air inlet pipe and damaging the fan body.

[0019] Preferably, the first clamping member and the second clamping member are spaced apart, and the ends of the unit tubes that are close to each other extend out of the first clamping member and the second clamping member.

[0020] By adopting the above technical solution, it is convenient for welding robots to perform welding from various angles.

[0021] The outstanding advantages of this utility model compared to the prior art are:

[0022] 1. In the welding process, this utility model uses an integrated fan to blow away the sparks falling onto the unit tube, reducing the formation of protrusions on the unit tube by the sparks, which helps to improve the welding quality;

[0023] 2. In this utility model, the air inlet pipe faces the welding station and the air outlet pipe faces away from the welding station. During the operation of the integrated fan, some of the sparks that fly during welding can be absorbed through the air inlet pipe.

[0024] 3. In the welding process of this utility model, the first support frame and the second support frame drive the first branch pipe and the second branch pipe to move to the welding station for measurement. During the welding process, the main body of the fan works to blow away the sparks that fall after the spatter. After the welding is completed, the first support frame and the second support frame are moved away from each other, which drives the positioning first branch pipe and the second branch pipe to move away from the top of the unit pipe, so as to facilitate the removal of the unit pipe.

[0031] The present invention will be further described below with reference to specific embodiments:

[0032] This application discloses a welding device for assembling and splicing motorcycle frames. See also... Figure 1 and Figure 2 The system includes a welding robot 1 and a welding frame 2, both of which are supported on the ground. The welding frame 2 is equipped with a first clamping member 3 and a second clamping member 4, which are spaced apart and distributed horizontally. The distribution direction of the first clamping member 3 and the second clamping member 4 is parallel to the length direction of the welding frame 2. The first clamping member 3 and the second clamping member 4 are used to clamp unit tubes. A welding station 7 is provided between the first clamping member 3 and the second clamping member 4. The ends of the clamped unit tubes that are close to each other extend out of the first clamping member 3 and the second clamping member 4, so that the connection of the unit tubes is located within the welding station 7. The welding robot 1 welds the unit tubes within the welding station 7.

[0033] See Figure 1 and Figure 2 The first clamping component 3 includes a first support part 31 and a first clamping part 32. The first support part 31 is fixed to the welding frame 2 by screws and nuts. The first clamping part 32 and the first support part 31 are spliced ​​together to form a first clamping station 33 adapted to the unit tube to be welded. The first clamping part 32 is a hydraulic plate or a pneumatic pressure plate. The second clamping part 42 includes a second support part 41 and a second clamping part 42. The connection method between the second support part 41 and the welding frame 2 is the same as that of the first support part 31. The second clamping part 42 and the first support part 31 are spliced ​​together to form a second clamping station 43. The second clamping part 42 is a hydraulic plate or a pneumatic pressure plate.

[0034] During welding, the two unit tubes to be welded are clamped and fixed by the first clamping part 32 and the second clamping part 42 respectively. Then, the welding robot 1 welds the ends of the unit tubes in the welding station 7. After welding is completed, the first clamping part 32 and the second clamping part 42 release the unit tube and remove the welded unit tube. When it is necessary to weld the unit tube in another basic unit, the screws and nuts are removed and the corresponding other set of first clamping parts 3 and second clamping parts 4 are installed.

[0035] See Figure 2 and Figure 3An integrated fan 5 is installed on the welding frame 2. The integrated fan 5 includes a fan body 51, an inlet pipe 52, and an outlet pipe 53. The fan body 51 is fixed to the welding frame 2 and is located below the first clamping part 32 and the second clamping part 42. The fan body 51 is provided with an outlet 511 and an inlet 512, which are located at opposite ends of the fan body 51. One end of the inlet pipe 52 and the outlet pipe 53 are fixedly connected to the fan body 51. The inlet pipe 52 is located on the side of the fan body 51 closest to the inlet 512. The end of the inlet pipe 52 away from the fan body 51 is fixedly connected to the welding frame 2. The end of the inlet pipe 52 away from the fan body 51 is located below the welding station 7. When the fan body 51 is working, some of the sparks that splash from the welding station 7 enter the inlet pipe 52.

[0036] See Figure 4 and Figure 5 A filter chamber 6 is fixed to the air inlet duct 52. The filter chamber 6 protrudes from the air inlet duct 52 and is fixed to the welding frame 2. The filter chamber 6 is used to collect sparks drawn into the air inlet duct 52. The filter chamber 6 includes a slag storage box 61 and a filter plate 62. The slag storage box 61 is located outside the air inlet duct 52, and one end of the slag storage box 61 is connected to the air inlet duct 52. The slag storage box 61 is welded to the air inlet duct 52. The filter plate 62 is located inside the air inlet duct 52 and is inclined downward along the direction close to the slag storage box 61. The filter chamber 6 is used to prevent sparks entering the air inlet duct 52 from entering the fan body 51 and causing damage to the fan body 51.

[0037] See Figure 2 and Figure 3The air outlet duct 53 is located on the side of the fan body 51 near the air outlet 511. The air outlet duct 53 includes a main duct 531, a first branch duct 532, and a second branch duct 533. The main duct 531 is fixedly connected to the fan body 51. One end of the first branch duct 532 and the second branch duct 533 are fixed to the main duct 531. The first branch duct 532 and the second branch duct 533 are interconnected through the main duct 531. The first branch duct 532 and the second branch duct 533 are connected to the air outlet 511 through the main duct 531. The diameter of the first branch duct 532 and the second branch duct 533 is smaller than the diameter of the air inlet duct 52. The end of the first branch duct 532 and the second branch duct 533 away from the fan body 51 each includes an air guide block 535. The air guide block 535 has several interconnected air outlet channels 536, and each air outlet channel 536 is connected to the first branch 532 or the second branch duct 533. During welding, several air outlet channels 536 are positioned away from the welding station 7. The angle between the axis of the air outlet channel 536 and the distribution direction of the first support 31 and the second support 41 is 0°-15°. In this embodiment, the angle is 0°. The axis of the air outlet channel 536 is parallel to the distribution direction of the first support 31 and the second support 41. The ends of the several air outlet channels 536 away from the air outlet 511 are arranged around the unit pipe. The air guide block 535 installed on the first branch pipe 532 is located above the first support 31, and the air guide block 535 installed on the second branch pipe 533 is located above the second support 41.

[0038] After the first support part 31 and the second support part 41 are installed and fixed to the welding frame 2, the first clamping station 33 and the second clamping station 43 are located above the corresponding first support part 31 and the second support part 41, and the first support part 31 and the second support part 41 are inclinedly supported on the welding frame 2.

[0039] A first support frame 21 and a second support frame 22 are slidably connected to the welding frame 2. The first support frame 21 is located on the side of the welding station 7 near the first support part 31, and the second support frame 22 is located on the side of the welding station 7 near the second support part 41. The first support frame 21 is located above the first support part 31, and the second support frame 22 is located above the second support part 41. The sliding direction of the first support frame 21 and the second support frame 22 is parallel to the distribution direction of the first support part 31 and the second support part 41. The first support frame 21 is fixedly connected to the first branch pipe 532, and the second support frame 22 is fixedly connected to the second branch pipe 533. The movement of the first support frame 21 and the second support frame 22 causes the air guide blocks 535 on the first branch pipe 532 and the second branch pipe 533 to move closer to or further away from each other.

[0040] After clamping the unit tube, the first support frame 21 and the second support frame 22 move towards each other, causing the ends of the first branch pipe 532 and the second branch pipe 533 away from the fan body 51 to move closer to the welding station 7, so that the air guide block 535 is located above the first clamping station 33 and the second clamping station 43 respectively. The welding robot 1 welds the connection in the welding station 7. The fan body 51 works to make the airflow in the welding station 7 flow into the air inlet pipe 52, so that some of the sparks generated during the welding process enter the air inlet pipe 52 with the airflow. The sparks that do not enter the air inlet pipe 52 splash. The air at the first branch pipe 532 and the second branch pipe 533 is blown out from the air outlet channel 536, increasing the air velocity on the surface of the unit tube, dissipating heat from the unit tube located outside the welding station 7, and helping to blow away the sparks that are about to fall on the unit tube.

[0041] After welding is completed, the first support frame 21 and the second support frame 22 drive the ends of the first branch pipe 532 and the second branch pipe 533 away from the motor body to move away from the welding station 7, so that the air guide pipe and the welding frame 2 move away from the first clamping station 33 and the second clamping station 43, so that the first clamping part 32 and the second clamping part 42 can release the unit pipe and make it easier to remove the welded unit pipe.

[0042] The implementation principle of this application embodiment is as follows: During the actual welding process, after the unit tube is clamped and fixed, the first support frame 21 and the second support move the air guide block 535 to move above the first clamping station 33 and the second clamping station 43. The fan body 51 is started, and the welding robot 1 welds the unit tube. During the welding process, the air inlet pipe 52 near the welding station 7 collects some of the sparks, and the first branch pipe 532 and the second branch pipe 533 near the surface of the unit tube blow the sparks falling on the unit tube away from the unit tube, reducing the number of sparks falling on the surface of the unit tube and forming protrusions, which is beneficial to improving the welding quality.

[0043] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
