[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle and is equipped with a motor, controller, battery, handlebars, brake handles and other operating components and a display instrument system.

[0003] Whether an electric bicycle is firm and safe has a great relationship with the quality of the vehicle bracket. The vehicle bracket is composed of multiple parts, including the head tube, beam tube and many small parts, which are welded together. However, the base for welding the existing electric bicycle bracket does not have any fixing mechanism. During welding, the processing components are easy to shift, resulting in unstable welding quality. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a welding clamping tool for an electric vehicle bracket.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is an axially-coupled device for translating a plurality of moving parts into and out of the two guide wheels, and the moving parts are connected to the respective guide wheels via a plurality of threaded connections. The moving parts are connected to the respective guide wheels via a plurality of threaded connections. The moving parts are connected to the respective guide wheels via a plurality of threaded connections.

[0007] Preferably, two guide grooves are provided on the inner wall of the bottom of the base, and two guide blocks are slidably installed in the two guide grooves respectively.

[0008] Preferably, the sleeve and the screw rod are movably sleeved with a same spring, and two ends of the spring are respectively fixedly mounted on the sides of the clamping plate and the fixing plate that are close to each other.

[0009] Preferably, a driven bevel gear located between two fixed plates is fixedly sleeved on the sleeve, and the driven bevel gear is meshed with the driving bevel gear.

[0010] Preferably, a hinged seat is fixedly mounted on one side of the base close to the rotating wheel, and a fixed block is rotatably mounted on the hinged seat.

[0011] Preferably, a plurality of fixing grooves are evenly and equidistantly formed on the side wall of the rotating wheel, and the fixing grooves are matched with the fixing blocks.

[0012] In the utility model, the electric vehicle bracket welding clamping tool is used by placing the processing device on the top of the base, rotating the rotating wheel, driving the power shaft fixedly connected to the rotating wheel to rotate, and then driving the active bevel gear fixedly sleeved on one end of the power shaft to rotate. Since the active bevel gear and the driven bevel gear are meshed, the driven bevel gear can be driven to rotate. Since the driven bevel gear is fixedly sleeved on the sleeve, the sleeve can be driven to rotate. Due to the setting of the guide block and the guide groove, the splint can only move horizontally along the guide groove, and then the screw rod fixedly connected to the splint can only It can move horizontally, because the two screws are respectively threadedly installed at the two ends of the sleeve, and the two screw threads are set in opposite directions, so as the sleeve rotates, it can drive the two screws to move horizontally and approach each other, thereby driving the two clamps to approach each other and compressing the two springs. When the two clamps clamp the processing device, stop rotating the wheel, and then rotate the fixed block counterclockwise so that the fixed block is inserted into the fixed groove, thereby limiting the rotation of the wheel. At the same time, the setting of the rubber pad can effectively prevent the processing device from sliding, and then complete the clamping and fixing of the processing device. The utility model has a compact structure, a reasonable design, and is easy to operate. It can clamp and fix the processing device. At the same time, the rubber pad can effectively prevent the processing device from sliding, ensure the stability of the welding quality, and is convenient for people to use.

The top ends of the two splints 8 extend to the top of the base 3. The top ends of the two splints 8 that are close to each other are fixedly installed with rubber pads 9. The setting of the rubber pads 9 can play an anti-skid role. The bottom ends of the two splints 8 are fixedly installed with guide blocks 10. A mounting hole 13 is provided on one side of the base 3. A power shaft 14 is rotatably installed in the mounting hole 13. One end of the power shaft 14 extends to the outside of the base 3 and is fixedly installed with a rotating wheel 15. The other end of the power shaft 14 extends into the base 3 and is fixedly sleeved with an active bevel gear 16. By rotating the rotating wheel 15, the active bevel gear 16 can be driven to rotate through the power shaft 14.

[0019] In the utility model, two guide grooves 11 are provided on the inner wall of the bottom of the base 3 , and two guide blocks 10 are respectively slidably installed in the two guide grooves 11 . The two guide blocks 10 can slide horizontally along the two guide grooves 11 .

[0020] In the utility model, the same spring 12 is movably sleeved on the sleeve 6 and the screw rod 7, and the two ends of the spring 12 are respectively fixedly mounted on the side where the clamping plate 8 and the fixed plate 4 are close to each other. The setting of the spring 12 can make the clamping plate 8 return to the initial position when no force is applied.

[0021] In the present invention, a driven bevel gear 17 located between two fixed plates 4 is fixedly sleeved on the sleeve 6, and the driven bevel gear 17 is meshed with the active bevel gear 16. The active bevel gear 16 rotates to drive the driven bevel gear 17 to rotate, thereby rotating the sleeve 6.

[0022] In the utility model, a hinge seat 18 is fixedly installed on one side of the base 3 close to the rotating wheel 15 , and a fixing block 19 is rotatably installed on the hinge seat 18 , and the fixing block 19 can rotate around the hinge seat 18 as the center.
