The application guarantees the machining precision, effectively improves the debugging efficiency, reduces the labor consumption and raw material waste, effectively reduces the energy consumption, is energy-saving and environment-friendly, and guarantees the machining quality.

The utility model relates to the technical field of electric vehicle production, in particular to a fixing device which is used for fixing a vertical pipe, a handle pipe and a shoulder cover of an upper fork of an electric vehicle during welding and comprises a support, a clamping mechanism, a first positioning mechanism, a second positioning mechanism and a power mechanism. The clamping mechanism is arranged at the bottom end of the support and can rotate along the axis of the clamping mechanism so that the vertical pipe can be fixed to the support. The top end of the vertical pipe is inserted into a middle hole of the shoulder cover, and the first positioning mechanism is arranged on the side wall of the support and used for limiting the position of the shoulder cover. A handle pipe is arranged on the side, away from the vertical pipe, of the shoulder cover, the second positioning mechanism and the first positioning mechanism are arranged on the support in parallel, and the output end of the power mechanism is in transmission connection with the second positioning mechanism so as to drive the second positioning mechanism to move in the length direction and the height direction of the support and limit the position of the handle pipe. According to the fixing device, the production precision of the upper fork can be guaranteed, secondary manual correction is not needed, and therefore the labor cost is reduced.

The utility model discloses a bending device for U-shaped buckle production, which comprises a working table, a portal frame is erected on the working table, a horizontally arranged rotating seat is rotatably arranged on the working table, and the rotating seat is connected with a rotating driving mechanism; a supporting column which is vertically and upwards arranged, penetrates through the center of the rotating base and is coaxial with the rotating base is fixedly arranged on the workbench, and a fixing mold used for limiting and guiding the metal strip from one side of the metal strip is arranged at the top of the supporting column. A bending mechanism which can be far away from and close to the fixed mold, is used for being matched with the fixed mold and is used for bending the metal strip from the other side of the metal strip under the rotating action of the rotating seat to form a U-shaped buckle is arranged on the rotating seat; the portal frame is provided with a clamping mechanism which can be far away from and close to the workbench so as to clamp the metal strip from one end of the metal strip. The device is high in production efficiency and machining precision and wide in application range.
