Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically a tooling for calibrating the welding angle of a motorcycle handlebar stem. Background Technology

[0002] The handlebar stem is a core safety component connecting the handlebars and the frame seat tube. Its welding angle directly determines the handlebar steering characteristics, riding stability, and handling safety. According to industry standards, the welding angle error between the handlebar stem and the frame seat tube must be controlled within ±0.5°. Otherwise, it may lead to risks such as "steering deviation" and "straight-line deviation" while riding, and in severe cases, cause safety accidents. As the motorcycle manufacturing industry upgrades towards "high precision and high safety," and as consumers' requirements for riding experience increase, the welding quality of the handlebar stem (especially the angle accuracy) has become a core aspect of overall vehicle quality control.

[0003] Meanwhile, a welding fixture with application number CN201220539601.6 is described. It consists of two columns with a diameter 0.1mm to 0.4mm smaller than the flange bolt hole diameter. The length of the columns is equal to that of the pipe fitting. A horizontal plate is mounted on the top of the two columns. The length of the horizontal plate is equal to the distance between the centers of the diagonal bolt holes of the flange. The beneficial effect of this utility model is that when welding the flange to the steel pipe and calibrating whether the bolt holes of the flanges at both ends are aligned, the fixture can be directly inserted into the bolt holes of the flanges on both sides, which can well ensure the alignment of the upper and lower flange bolt holes and ensure the welding quality of the pipe fitting.

[0004] However, the following problems were found in the implementation of the relevant technology: it lacks precise angle adjustment and quantitative display functions, and its fixed angle positioning structure cannot adapt to the angle differences of different workpieces. If the specifications are changed, the tooling needs to be replaced as a whole or complex debugging needs to be carried out, which is difficult to meet the needs of flexible production. Moreover, its angle calibration depends on the operator to manually measure with an angle ruler and level, which has a large reading error and requires repeated adjustment and multiple measurements. This is not only inefficient, but also causes poor angle consistency in batch production due to human judgment differences, which can easily lead to batch scrap.

[0005] To address this, we propose a tooling for calibrating the welding angle of motorcycle handlebar stems. Utility Model Content

[0027] Furthermore, the fixed plate 13 is provided with a threaded hole, the adjusting bolt 14 is threadedly connected to the threaded hole, and the other end of the adjusting bolt 14 is fixedly connected to the control block 15.

[0028] It is worth noting that the base plate 1 is provided with a slot 18, and a placement block 19 is slidably connected in the slot 18.

[0029] It is worth noting that the placement block 19 is provided with a slot for fixing another welded part inside the placement block 19.

The position of the placement block 19 is adjusted in conjunction with the second scale 20 to accurately position the welded part. Then, the motor 4 on the mounting base 3 rotates the rotating rod 5, which drives the rotating plate 6 to rotate, thereby adjusting the angle of the rotating plate 6. The angle of the rotating plate 6 is precisely displayed by the pointer 16 sliding within the annular groove 17. Then, another welded part is placed between the fixed retaining ring 9 and the movable retaining ring 12. The adjusting bolt 14 is rotated by the control block 15. The adjusting bolt 14 moves during rotation due to the action of the thread. During the movement of the adjusting bolt 14, the movable retaining ring 12 is pushed closer to the fixed retaining ring 9, thereby clamping and fixing the welded part through the movable retaining ring 12 and the fixed retaining ring 9, thus completing the fixing and positioning of the two welded parts.
