Disclosure of utility model
In order to solve the defects in the prior art, the utility model provides the lamp post overhauling door frame correction device which has higher correction speed and can effectively prevent the long side of the door frame from deforming.
In order to achieve the object of the utility model, the following scheme is adopted:
a lamp post overhaul door frame correction device, comprising: the pair of parallel and interval support bars, and the spaced width is less than the length of door frame minor face, and the top surface of two support bars is in the coplanar, and the top of support bar is equipped with vertical decurrent hydraulic means, is equipped with a pair of side shield that are parallel to each other between its and the hydraulic means, and the side shield is on a parallel with the support bar, and the distance between the side shield is adjustable.
The utility model has the beneficial effects that:
1. Through controlling hydraulic means's stroke, alright accurate control is to the correction degree of door frame, effectively reduces the process of repeated comparison test dress, improves production efficiency.
2. When in correction, the two side baffles are respectively contacted with the outer walls of the two long sides of the door frame to limit the long sides of the door frame, so that the long sides of the door frame are prevented from outwards protruding and deforming during correction.
