Welding fork for stand pipe of motorcycle

Abstract

The invention discloses a welding fork for a stand pipe of a motorcycle. A bracket is arranged on a first positioning plate; a suspension section is arranged at the top of the bracket; a first positioning through slot is arranged at the top of the suspension section; a positioning block and a stand plate are fixed on a second positioning plate; a second positioning through slot is arranged on thetop surface of the positioning block; the second positioning through slot is arranged right below the first positioning through slot; a third positioning plate is fixed at the top of the stand plate;a quick chuck is arranged at the upper end of the third positioning plate; a connecting rod of the quick chuck is connected with the upper end of a guide post; a first positioning seat is arranged atthe lower end of the guide post; a second positioning seat is arranged right below the first positioning seat; and the second positioning seat is fixed on the second positioning plate. by the weldingfork, a direction lock block, a direction stop block and the stand post can be simultaneously positioned; on one hand, the accuracy of the positions of a scutcheon hole, the direction lock block and the direction stop block can be guaranteed; and on the other hand, the working procedures are effectively reduced, the operation is simple and convenient, and the welding efficiency is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to welding fixtures for motorcycle standpipes. Background technique [0002] The seat tube is located at the very front of the motorcycle frame and is used to pass through the steering column. A direction lock block and a direction limit block are respectively welded on the upper and lower ends of the motorcycle standpipe, so as to lock the front of the motorcycle when the motorcycle is parked and prevent it from being stolen. A label hole is provided under the direction lock block for installing a label. [0003] At present, when each motorcycle manufacturer welds the vehicle frame, it needs to position the direction locking block and the direction limiting block respectively by means of two toolings, so that the direction locking block and the direction limiting block can be welded on the standpipe. Using two tooling for positioning is not only complicated in proces...

AI Technical Summary

Problems solved by technology

The positioning of two tooling is not only complicated in process, cumbersome in operation, low in efficiency, but also difficult in alignment, and it is difficult to ensure the accuracy of the installation position of the direction lock block or the direction limit block

The sign hole on the riser is usually drilled with a hand drill after the frame of the whole vehicle is welded. Because the frame is not well positioned, it is easy to swing when drilling. On the one hand, it will increase the difficulty of drilling. It will cause inaccurate hole positions of the signage holes, making it difficult to meet the requirements of consistent production
