Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] like Figure 1-3 As shown, a two-wheeled electric vehicle frame welding fixture proposed in an embodiment of the utility model comprises a fixture body 1 of two symmetrical parts, the fixture body 1 comprises a frame 2, a foot cup 3 is provided at the bottom of the frame 2, a servo motor 4 is installed on the frame 2, an active chain plate 6 is fixedly connected to the output end of the servo motor 4, a chain belt 8 is meshed and transmitted on the active chain plate 6, a driven chain plate 7 is meshed and transmitted on the chain belt 8, a screw rod 9 is fixedly connected at the center of the driven chain plate 7, the screw rod 9 is rotatably mounted on a bearing seat 10, a screw block 11 is threadedly connected to the screw rod 9, a mounting plate 13 is fixed on the top of the screw block 11, a hole is provided on the mounting plate 13, the mounting plate 13 is fastened to the fixture plate 14 by bolts, a connecting block 12 is fixedly connected to the side of the mounting plate 13, a guide block 15 is fixedly connected to the bottom of the connecting block 12, and the guide block 15 is engaged and slid on the guide rail 16;

[0030] The clamp body 1 has two symmetrical parts: ensuring that the frame can be fixed and clamped evenly from both sides, ensuring the balance and stability of the clamping.

[0031] The foot cup 3 at the bottom of the frame 2: The foot cup 3 is threadedly connected to the frame 2 and is further fastened by bolts. The height and levelness can be adjusted so that the fixture can be stably placed on the workbench during operation.

[0032] The transmission system of the servo motor 4, the active chain plate 6, the chain belt 8 and the driven chain plate 7 realizes the transmission of power and provides precise drive for the adjustment of the clamp.

[0033] The screw rod 9 rotatably mounted on the bearing seat 10 and the screw block 11 threadedly connected thereto convert the rotational motion into linear motion, thereby driving the fixture plate 14 to adjust its position.

[0034] T-shaped fixture plate 14 with mounting holes: The T-shaped design increases the contact area and the stability of the clamping, and the mounting holes facilitate flexible adjustment and fixation according to the shapes and sizes of different frame components. The rounded corner design at the end of the fixture plate 14 reduces possible scratches and damages to the frame components.

[0035] The connecting block 12, the guide block 15 and the guide rail 16 ensure the linearity and stability of the mounting plate 13 and the fixture plate 14 during movement, and prevent deviation and shaking.

[0036] The shield 5 on the side of the frame 2 protects the transmission components, prevents external debris from interfering with the transmission, and also ensures the safety of the operator.

[0037] Working principle:

[0038] When the frame of the two-wheeled electric vehicle needs to be welded, the frame components are placed between the two fixture plates 14. The servo motor 4 is started, and the output end of the servo motor 4 drives the active chain plate 6 to rotate. The active chain plate 6 drives the driven chain plate 7 to rotate through the chain belt 8.

[0039] Since the driven chain plate 7 is fixedly connected to the screw rod 9 , the rotation of the driven chain plate 7 drives the screw rod 9 to rotate in the bearing seat 10 .

[0040] The rotation of the screw rod 9 causes the screw block 11 threadedly connected thereto to produce a linear motion. The mounting plate 13 on the top of the screw block 11 moves accordingly, driving the clamp plate 14 to clamp and fix the frame components for subsequent welding work.

[0041] During the movement, the guide block 15 at the bottom of the connecting block 12 on the side of the mounting plate 13 slides along the guide rail 16 to ensure smooth and linear movement, thereby achieving accurate position adjustment and fixation of the frame components.

[0042] In this way, during the welding process, the frame components can be stably and accurately fixed in the required position to ensure the quality and accuracy of the welding.

[0043] like Figure 2 As shown, in some embodiments, the foot cup 3 is threadedly connected to the frame 2, and the threaded bolts on the foot cup 3 are fastened to the frame 2; the threaded connection allows the foot cup 3 to rotate and extend relative to the frame 2 within a certain range, so that the overall height of the clamp can be easily adjusted to adapt to different working planes and operating requirements.

[0044] like Figure 2As shown, in some embodiments, there are two bearing seats 10, and the bearing seats 10 are installed on the top of the frame 2; the two bearing seats 10 can share the load of the screw 9 more evenly, ensuring that the forces at both ends of the screw 9 are balanced when rotating, reducing deformation or wear caused by uneven force on one side, thereby improving the rotation stability and service life of the screw 9.

[0045] like Figure 1 As shown, in some embodiments, the fixture plate 14 is a T-shaped plate, and a plurality of mounting holes are arranged on the fixture plate 14; the T-shaped design increases the contact area between the fixture plate 14 and the frame component, can provide more stable support and clamping, and reduce the shaking of the frame component during the welding process; the provision of multiple mounting holes enables the fixture plate 14 to adapt to frame components of different shapes and sizes. The appropriate fixture plate 14 can be selected to fix the frame component according to actual needs, which increases the versatility of the fixture.

[0046] like Figure 1 As shown, in some embodiments, the end of the clamp plate 14 is designed with rounded corners; when it contacts the frame component, it will not cause scratches or indentations on the surface, thereby ensuring the quality and appearance of the frame component.

[0047] like Figure 3 As shown, in some embodiments, there are two guide rails 16, which are respectively arranged on both sides of the top of the frame 2; the two guide rails 16 can guide the movement of the mounting plate 13 and the components thereon in a balanced manner to ensure a smooth movement process without tilting or offsetting.

[0048] like Figure 1 As shown, in some embodiments, a guard 5 is provided on the side of the frame 2, and the guard 5 protects the active chain plate 6, the driven chain plate 7 and the chain belt 8; it prevents the operator from accidentally contacting the high-speed running chain plate and the chain belt 8 during work, thereby avoiding personal injury.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
