Car frame front tube shaping device

Abstract

The invention relates to a car frame front tube shaping device, which comprises a base, a car frame positioning assembly and a car frame front tube shaping assembly, wherein the car frame positioningassembly and the car frame front tube shaping assembly are arranged on the base. The car frame front tube shaping assembly comprises an integral deviation correction mechanism, a front tube torsion deviation correction mechanism and a front tube correction detection mechanism, the integral deviation correction mechanism comprises a first servo electric cylinder, a front tube shaping layer board, aguide rail, a torsion deviation plate, a torsion deviation base and a torsion deviation plate locking oil cylinder, the guide rail and the torsion deviation base are both arranged on the base, the front tube shaping layer board is slidably matched with the guide rail, a top rod of the first servo electric cylinder is fixedly connected with the front tube shaping layer board, the torsion deviationplate is rotatably connected with the torsion deviation base through a bearing, a locking hole is formed in the torsion deviation plate, the torsion deviation plate locking oil cylinder is installedon the torsion deviation base and driven, and a piston rod of the torsion deviation plate locking oil cylinder can be inserted in or detached from the locking hole of the torsion deviation plate. According to the car frame front tube shaping device, closed-loop correction can be formed, thus correction accuracy is high, and the correction efficiency is also high.

Description

technical field [0001] The invention relates to a shaping device, in particular to a motorcycle frame front pipe shaping device. Background technique [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, and the overall deviation is required to be controlled within ±0.5mm. Therefore, it is necessary to reshape the welded 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...

[0002] The existing motorcycle frame is a welded part, and the front tube and tail of the frame are easily deformed after welding.

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
