Arc-shaped opening correcting tool

Abstract

The invention discloses an arc-shaped opening correcting tool. The tool comprises a reference seat, a support and a rolling wheel, wherein the reference seat is provided with a profiling curved surface matched with an arc-shaped opening of a workpiece; the support is connected to the reference seat; and the rolling wheel is arranged in the bending center direction of the profiling curved surface, the rolling wheel is provided with an eccentric driving shaft, the driving shaft is installed on the support through a bearing, and the rolling wheel can rotate around the driving shaft and is matched with the profiling curved surface to roll a workpiece located between the reference base and the rolling wheel. The reference seat adopts a profiling design and is equivalent to an original curved surface reference of an opening part, comparison can be performed during repair, and the effect is clear. And during repairing, a plate does not need to be knocked, the extension condition cannot be generated, and the thinning risk of the plate is effectively reduced. The stress is uniform in the rolling process, the forming effect is good, undesirable problems such as pits are avoided, and the repairing quality is effectively improved. The tool is convenient to use, deformed parts can be repaired by directly driving the rolling wheel through the driving shaft after installation, and the efficiency is very high.

Description

technical field [0001] The invention is used in the field of automobile maintenance tools, and in particular relates to an arc opening correction tool. Background technique [0002] The opening of the trunk of the car is the main location for the installation of waterproof rubber strips. The opening is made of a single-layer steel plate (about 0.6-0.7mm, the plate is thin and easy to deform), and the processing process will be affected by external factors. Deformation (such as deformation after collision, etc.). The opening is uneven, and water leakage will occur when the waterproof rubber strip is installed (the rubber strip does not fit, and the sealing is poor), so the flatness requirement of this position is very high. Once the deformation occurs at the corner, it is more difficult to repair (there is a curved surface at the corner, and it is difficult to correct the curved parts), and it cannot be repaired according to the current existing methods.
