[0002] The existing motorcycle frame is a welded part, and the front tube and tail of the frame are easily deformed after welding. In order to ensure that the frame can meet the safety requirements, that is, the front tube has high torsion accuracy requirements, and the torsion accuracy Control within ±0.3mm, the overall deviation is required to be controlled within ±0.5mm, the overall height accuracy of the tail of the frame is required to be controlled within ±1.0mm, and the height difference between the left and right sides of the tail is required to be controlled within ±0.5mm. Shaping the frame

The existing frame shaping device has a horizontal structure. The upper and lower ends of the front tube of the frame are measured by a static mechanical linear gauge to obtain the error between the actual measured value and the set reference value. The oil cylinder is used as the correction power to correct the error first. The head tube is twisted, and the overall deviation of the front tube is corrected. At the same time, the response sensitivity of the traditional oil cylinder is low, and the action has a certain slowness. There is a situation where the shaping is not in place, making the correction accuracy poor
