Elastic rolling support roller device and guide method of assembled heavy single-acting oil cylinder plunger

Abstract

The invention discloses an elastic rolling support roller device. The elastic rolling support roller device comprises a base, shaft frames, elastic support rollers and lead screws, wherein the base is a box structure symmetrical about center; the upper end surface of the box structure is concavely arched; support roller adjusting holes are symmetrically formed at the two sides of the upper end of the box structure; the center axle extension lines of the support roller adjusting holes are intersected at the inner side of the concavely arched shape; the shaft frames are arranged in the support roller adjusting holes, and are cylinders; the upper ends of the shaft frames are U-shaped grooves communicated from front to back, and the lower ends are hollow cylinders; the elastic support rollers are arranged in the U-shaped grooves, and consist of roller frames with metal materials and roller surfaces cast on the surfaces of the roller frames and with elasticity and nonmetal materials; the roller frames are hollow cylinders; support roller shafts are coaxially arranged at the hollow parts in the elastic support rollers; the two ends of the support roller shafts are respectively fixed on two side groove surfaces of the U-shaped grooves; and the lead screws are cylindrical, are arranged in the hollow parts of the cylinders at the lower ends of the shaft frames, and are fixed on the base.

Description

technical field [0001] The invention belongs to the technical field of heavy machinery manufacturing, and in particular relates to an elastic rolling idler device and a guiding method for assembling a plunger of a heavy single-acting oil cylinder. Background technique [0002] It is known that in mechanical manufacturing, the assembly of the plunger and the cylinder body of a heavy-duty single-acting oil cylinder is a difficult assembly work, and the difficulty is mainly caused by the structural size and weight of the plunger. [0003] Heavy duty single acting cylinders such as figure 1 As shown, it is mainly composed of cylinder block 1, plunger 2, guide copper sleeve 3, sealing ring 4, cylinder head 5, dustproof ring 6, bolt 7 and gasket 8, etc. The outer circle of the guide copper sleeve 3 and the inner hole of the cylinder body 1 are generally a transition fit or a small interference fit, while the inner hole of the guide copper sleeve 3 and the outer circle of the plun...
