[0002] The front triangle frame of existing bicycle comprises left support bar, right support bar and head tube, and one end of its left support bar and right support bar is close to, and is welded on the head tube, and the other end of left support bar and right support bar There are front claws formed, and slots are formed on the front claws. When the front tripod is assembled, the left support rod, right support rod and head pipe are generally placed on the horizontal workbench, and the left support rod and the head pipe are positioned first so that the left support rod and the One end of the right support rod is close to each other and welded to the head pipe by spot welding. When welding, each part needs to be fixed by hand, and the left and right support rods are pressed by hand or other tools. There is no special positioning device and pressing device, when spot welding is positioned, improper force will cause the left support rod, right support rod or head pipe to deviate, thereby welding the wrong position, affecting product quality, making it difficult to operate and reducing production efficiency

The invention discloses a pressure rod adjustment device of a bicycle front tripod assembling die, relating to the technical field of bicycle manufacture equipment. The pressure rod adjustment device comprises a fixed block, wherein a support plate is fixed above the fixed block, a through groove is formed in the support plate, an adjusting bolt passes through the through groove and is in threaded connection onto a connection rod so as to fix the connection rod on the support plate, a pressure rod is fixed onto the connection rod, and a pressure block is fixed to the end of the pressure rod. When a bicycle front tripod is assembled, the pressure rod adjustment device can be used for pressing a left support rod and a right support rod to prevent the two support rods from deviating, and can cooperate with other positioning devices of the bicycle front tripod to prevent the bicycle front tripod from deviating during spot welding positioning, thereby enhancing product quality, lowering operation difficulty and improving production efficiency.
