Description

Technical Field

[0001] The present invention relates to the technical field of safety welding devices, and particularly relates to an adjustable safety welding device for the frame of a two-wheeled electric vehicle that is convenient to use. Background Art

[0002] With the improvement of environmental awareness and the increasing demand for convenient means of transportation, the use of two-wheeled electric vehicles is becoming more and more widespread. During the production process of two-wheeled electric vehicles, the welding of the frame is one of the key links. The quality of the frame welding directly affects the safety and service life of the electric vehicle.

[0003] When welding the frame of a two-wheeled electric vehicle, it is necessary to weld multiple positions on the main members of the frame of the two-wheeled electric vehicle, and then extend to the welding positions of the welded parts for re-welding. Usually, the operator needs to move to multiple positions for welding, and then take the auxiliary fixing mechanism to completely fit the workpiece to be welded on the welding surface of the main member of the frame of the two-wheeled electric vehicle. At this time, it is necessary to take the auxiliary fixing mechanism multiple times, which takes a lot of time. Moreover, some welding positions on the main member of the frame of the two-wheeled electric vehicle are not convenient for the operator to weld, and it is necessary to remove and re-fix the main member of the frame of the two-wheeled electric vehicle in a new state for welding. The above existing problems result in not very high efficiency when welding the frame of a two-wheeled electric vehicle.

[0004] In order to improve the welding efficiency of the frame of a two-wheeled electric vehicle, an adjustable safety welding device for the frame of a two-wheeled electric vehicle has been designed, which can adjust the position of the fixed frame of the two-wheeled electric vehicle, so that multiple welding positions of the frame of the two-wheeled electric vehicle can be moved to a determined position. Cooperating with the mechanism for fixing the workpiece to be welded, it is convenient to completely fit the welding surface of the frame of the two-wheeled electric vehicle and the welding surface of the workpiece to be welded, which is convenient for efficient welding. Summary of the Invention

The present invention provides an adjustable safety welding device for the frame of a two-wheeled electric vehicle, which can adjust the position of the fixed frame of the two-wheeled electric vehicle, so that multiple welding positions of the frame of the two-wheeled electric vehicle can be moved to a determined position. Cooperating with the mechanism for fixing the workpiece to be welded, it is convenient to completely fit the welding surface of the frame of the two-wheeled electric vehicle and the welding surface of the workpiece to be welded, which is convenient for efficient welding.

Start the second motor 37 to drive the first spline shaft 31, the spline bar 40, and the second spline bushing 32 to rotate, causing the connecting rod 17 to move up and down, thereby driving the main rod of the two-wheeled electric vehicle frame to move up and down, and adjusting the height of the main rod of the two-wheeled electric vehicle frame. Start and extend the electric telescopic member 28 so that the third spline bushing 38 moves upward, causing the spline bar 40 to be in a limited sliding connection within the first spline bushing 25. At this time, start the second motor 37 to drive the first spline bushing 25, the second bevel gear 12, the first bevel gear 11, the two rotating sleeves 19, and the third C-shaped plate 14 to rotate, causing the main rod of the two-wheeled electric vehicle frame to rotate back and forth to adjust the angle. It should be noted that at this time, the disc plate 16 will not move under the action of its own gravity and the friction force of the connecting rod 17. On the basis of the extension of the electric telescopic member 28, continue to extend it so that the mating plug post 26 is inserted into the mating round hole 24. At this time, start the second motor 37 again to make the main rod of the two-wheeled electric vehicle frame rotate horizontally by an angle, so that the welding position of the main rod of the two-wheeled electric vehicle frame moves to the required front position, and then start the first motor 5 to move the required welding position of the main rod of the two-wheeled electric vehicle frame to the required position. At this time, according to the shape of the welding position, place the workpiece to be welded at the second C-shaped plate 8 and fix it. Rotate the first extrusion threaded push rod 3 to make the welding position of the workpiece to be welded completely fit the required welding position of the main rod of the two-wheeled electric vehicle frame, and perform automatic welding or manual welding through the two welding mechanisms. And so on, so that multiple welding positions required on the two-wheeled electric vehicle frame are all welded at a determined position, and can be well fitted with the workpiece to be welded, facilitating efficient welding.
