Abstract

The invention relates to a shaft-distance-adjustable hydraulic floating roller driving device and belongs to the field of machinery. A T-shaped lead screw roller adjusting portion is installed on a drive end floating device, a reference measurement device is connected with the drive end floating device, a lifting bearing seat is fixed to the side face of the drive end floating device through a linear guide rail, spur gears III in the lifting bearing seat are meshed with spur gears I and are in rotary connection with two parallel roller seat assembly devices in the T-shaped lead screw roller adjusting portion through the spur gears I, and roller seat assemblies are in hinged connection with connecting arms. The shaft-distance-adjustable hydraulic floating roller driving device has the advantages of being novel in structure, capable of achieving all functions of a traditional roller driving device and meanwhile completely overcoming the shortcomings of the traditional roller driving device.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a driving device, which is widely used in the straightening drive of screw rods in the petroleum industry, the straightening drive of hydraulic engineering cylinder piston rods and cylinder barrels, and the straightening drive of various guide rods. Background technique [0002] The straightening machine driving device is a device that rotates and measures the workpiece during the straightening process, and it is also the mechanical reference for the workpiece rotation measurement. The driving device drives the workpiece to rotate one circle, and the displacement sensor and angle sensor feed back the runout value of the workpiece and the angle value of the workpiece rotation in real time. The control card samples at a certain sampling frequency, and corresponds the angle value and runout value at the same time to establish the measured value. Section runout-angle coordinate system. Due ...
