Description
Technical Field
[0001] This utility model relates to the field of welding clamping technology for the production of tricycle frame head tubes, specifically a welding device for the production of tricycle frame head tubes. Background Technology
[0002] The welding of the head tube in the tricycle frame is a crucial step in frame manufacturing, primarily involving the reliable connection of the head tube to other tubing (such as the main tube and lower tube). This welding process typically employs gas metal arc welding (GMAW), such as CO2 gas shielded welding or mixed gas shielded welding. In practice, the head tube and related tubing must be precisely positioned and fixed on specialized fixtures to ensure that the relative positions and angles between components meet design requirements. Appropriate beveling must be prepared at the welding points based on the material thickness and joint type to facilitate penetration and weld formation. The welding process requires continuous weld beads, performing full-circumference welding or fillet welds of specified lengths along the joint to achieve metallurgical bonding and form a permanent connection. The selection of welding parameters must comprehensively consider the base material, thickness, and joint type to ensure penetration and weld quality while controlling welding heat input to reduce welding deformation. This welding process has a decisive impact on the overall structural strength, rigidity, and dimensional accuracy of the frame.
[0003] Existing welding equipment clamping devices typically clamp the workpiece on the upper side of the base, which can easily result in a small exposed area of the workpiece, requiring it to be removed for welding of another part. Moreover, since the workpieces may vary in size, traditional devices mostly require manual clamping based on experience, which can easily lead to poor fit between each connector, resulting in misalignment gaps and other issues that affect the practical effect of the device.

[0012] Compared with the prior art, this utility model provides a welding equipment for the production of tricycle frame head tubes, which has the following beneficial effects: The positioning support mechanism is used to clamp pipes of different models. The mechanism centers the round pipe with a centering plate and clamps it with bolts, thereby preventing it from deviating from the optimal clamping position and causing gaps when it is used with other fixed clamping components, thus improving welding accuracy. At the same time, the mechanism fully exposes the welding surface by suspending the pipe, which improves welding efficiency.
[0013] The locking mechanism is used to clamp the workpiece with the positioning support mechanism. After the positioning support mechanism has positioned the workpiece, the mechanism uses a pusher to bring the workpiece close to the support tube, and with the help of rollers, gradually reduces the range of movement of the workpiece, forcing its notch to fit with the support tube. The positioning operation is simple and the clamping stability is strong. Attached Figure Description
