Description

Technical Field

[0002] The front fork is located at the front of the electric vehicle's structure. Its upper end connects to the handlebars, its frame mates with the head tube, and its lower end mates with the front axle, forming the electric vehicle's steering system. Rotating the handlebars and front fork changes the direction of the front wheel, thus guiding the electric vehicle and controlling its movement. The front fork is a crucial component for the comfort of an electric vehicle. During the production of the front fork's seat tube, it needs to be welded, and during welding, it must be clamped and fixed in place using a clamping device.

[0003] Existing electric vehicle front fork riser welding devices typically involve clamping the electric vehicle front fork riser with a clamping workpiece, and then fine-tuning its positioning again after clamping. This increases the time required for clamping and positioning before welding the electric vehicle front fork riser, seriously affecting welding efficiency. Utility Model Content

[0026] In this embodiment: During use, the fork's open end is inserted into two first placement cylinders 4 respectively. Then, multiple first clamping plates 5 move in opposite directions to clamp and fix the fork. Next, one end of the seat tube is inserted into a second placement cylinder 7. Then, two second clamping plates 8 move in opposite directions to clamp and fix the seat tube. Then, a first mounting block 3 and a second mounting block 6 move in opposite directions, causing the clamped and fixed fork and seat tube to move closer together and abut against each other. Because the center points of the two first placement cylinders 4 and the first...
