Folding brake hold-down mechanism.
Thus the technical scheme adopted by the utility model is
Including compression beam, compression beam upper end two sides are symmetrically arranged with several compressed oil cylinders, the piston of the compressed oil cylinder
Bar lower end is connect with compression beam, and the compressed oil cylinder is fixedly mounted on the rack, and the compression beam lower end is equipped with hemming die, described
The rear end face two sides of compression beam are symmetrically arranged with several linear guides, and the fixing piece of linear guide is fixedly connected with rack, compression beam
Rear end face among position be equipped with compensation device, the compensation device include servomotor, gear reducer, shaft coupling, eccentric shaft and
Compensating line guide rail, compensating line guide rail are mounted on the intermediate position of compression beam horizontal direction, the fixing piece of compensating line guide rail
By connecting plate and eccentric axis connection, servo motor drives speed reducer, and the output shaft of speed reducer is connected by shaft coupling and eccentric shaft
It connects, eccentric shaft both ends are cased with bearing respectively, and bearing is mounted in connection frame, and the connection frame is fixedly connected with rack, each pressure
Director valve is equipped at the oil inlet of locking oil cylinder.
As a further improvement of the above technical scheme, the rear end face of the compressed oil cylinder is equipped with fixed plate, the fixation
Plate is fixedly connected by bolt with rack.
As a further improvement of the above technical scheme, the linear guide and compensating line guide rail are that ball straight line is led
Rail.
As a further improvement of the above technical scheme, the bearing is radial bearing.
The utility model has the advantages that:
The utility model is simple and compact for structure, and integral rigidity is strong, passes through multiple compressed oil cylinders and uses smaller fulcrum spacing,
The deflection deformation between compression beam connecting fulcrum can be effectively suppressed, improve the uniformity of pressing force, can according to workpiece flanging length into
The pressure of the different compressed oil cylinders of row, avoids unnecessary energy consumption, compensation device can compensate intermediate deformation forward or backward
Amount offsets compression beam horizontal distortion amount, to guarantee workpiece straightness.
